FIG. 1 is a perspective view showing a schematic overall structure of a storage tank and a buffer support structure of the present invention, and FIG. 2 is a sectional view of the storage tank and the buffer support structure of the present invention as viewed from an upper surface.

1 and 2, the storage tank 100 and the buffer support structure of the present invention include a storage tank 100 in which a storage object is stored, and a storage tank 100 surrounding the side surface of the storage tank 100 And a lower frame 220 positioned at a lower end of the side frame 210 to support a lower end surface of the storage tank 100 and spaced apart from the ground at a predetermined height, A plurality of inner brackets 410 dispersed on the outer surface of the storage tank 100 and having at least one insertion hole 411 formed on one surface thereof and a plurality of inner brackets 410 dispersedly disposed on the inner surface of the side frame 210, A plurality of outer brackets 420 formed with one or more insertion holes 411 and a plurality of outer brackets 420 interposed between the inner brackets 410 and the outer brackets 420. Both ends are inserted into the insertion holes 411, And a coupling bar 430 that absorbs impact And buffering means (400).

First, the storage tank 100 is a storage object to be stored therein. Here, the object to be stored refers to a liquid or a gas, a solid material with good particles, and the like, for example, oil, gas or powdered sugar. They are characterized by the fact that they have no specific shape but they are bulky and can be stored in any form if they have space. Storing the storage object inside the storage tank 100 is referred to as a storage tank 100. The material of the storage tank 100 is preferably made of a steel or alloy material capable of holding its weight and pressure even if the storage object is filled in Do.

Here, the storage tank 100 includes a storage unit 110 for forming an internal space capable of storing a storage object in detail, and an inlet port through the upper end of the storage unit 110 so that the storage object can be inserted into the internal space And a discharge unit 130 having a discharge pipe extending from a lower end of the storage unit 110 to discharge a stored object stored in the internal space to the outside.

That is, a storage unit 110 in which a sufficient internal space is formed and a charging port penetrating through the upper end of the storage unit 110 are formed to put a storage object into the internal space of the storage unit 110, And a discharge pipe extending from the lower end of the storage unit 110 is formed for discharging the stored object to the outside. In particular, it is also possible to form a ventilating hole, which can be used when discharging the air originally present in the internal space at the time of charging, or when injecting two or more kinds of storage objects into the internal space. In addition, a separate cover may be further attached to the periphery of the inlet and the vent to cover the penetrated portion, if necessary, and a separate fixing portion may be provided on the surface of the storage portion 110 so that the cover can be fixed It is also possible to further form. In addition, in the case of the discharge pipe, it is possible to additionally include a valve, a stopper or the like in order to prevent indiscriminate discharge.

Next, the support structure 200 includes a side frame 210 surrounding the side surface of the storage tank 100, and a lower frame 210 positioned at the lower end of the side frame 210 to support the lower end surface of the storage tank 100, And a lower frame 220 spaced apart by a predetermined height. In other words, the support structure 200 is used as a kind of frame to support and fix the outer surface of the storage tank 100.

The lower frame 220 supports the lower end surface of the storage tank 100 and separates the lower end surface of the storage tank 100 from the ground by a predetermined height so as to prevent moisture from the ground, So that it can be protected. The side frame 210 surrounds the side surface of the storage tank 100 and prevents the storage tank 100 from collapsing or lying down in a lateral direction when an impact is received.

And further includes an upper frame 230 positioned at the upper end of the side frame 210 to cover a part of the upper surface of the storage tank 100. [ That is, the upper frame 230 is formed with a step formed at each corner of the upper frame 230, so that the upper frame 230 holds the upper surface of the storage tank 100. This is because, in the event of a severe rocking or impact, the upper surface of the storage tank 100 can be prevented from being separated from the support structure 200 only in addition to the lower surface or the side surface. The inner bracket 410 is dispersedly disposed on the upper surface of the storage tank 100 and the outer bracket 420 and the inner bracket 420 410 can be absorbed through the coupling bar 430 inserted into the insertion hole 411. [ This is the same as the above-described structure, but is formed only in the upper frame 230, so that detailed description will be omitted.

Even if strong vibration or impact is applied to the storage tank 100 or the support structure 200 even with such a configuration, the storage tank 100 or the support structure 200 may be damaged or broken by resonance or shaking due to vibration There is a disadvantage that it is difficult to prevent such a problem. And may further include a separate buffer means 400 positioned between the storage tank 100 and the support structure 200 to absorb the impact.

The structure of the buffer means 400 is as follows. A plurality of inner brackets 410 dispersed on the outer surface of the storage tank 100 and having at least one insertion hole 411 formed on one surface thereof and a plurality of inner brackets 410 dispersedly disposed on the inner surface of the side frame 210, A plurality of outer brackets 420 formed with at least one insertion hole 411 and a plurality of outer brackets 420 interposed between the inner brackets 410 and the outer brackets 420. Both ends are inserted into the insertion holes 411, And a coupling bar 430 for absorbing the fluid.

First, both the inner bracket 410 and the outer bracket 420 are identical in appearance and configuration but are divided according to their attachment positions. An inner bracket 410 dispersed on the outer surface of the storage tank 100 and an outer bracket 420 dispersed on the inner surface of the side frame 210. [ The bracket is characterized in that at least one insertion hole 411 is formed on one side thereof. The insertion hole 411 is formed such that the inner bracket 410 and the outer bracket 420 are inserted into the storage tank 100 or the side frame 210 in the direction opposite to each other.

The inner bracket 410 and the outer bracket 420 may have a rectangular parallelepiped shape and may have a shape such as an "a" or a "c" which surrounds an edge. Further, various shapes such as a hemisphere shape or a cylindrical shape Of course, may be applied. However, for convenience of explanation, the brackets having a "C" shape are mainly described in the drawings.

And a coupling bar 430 installed between the inner bracket 410 and the outer bracket 420 and having both ends inserted into the insertion hole 411 to absorb the impact. The coupling bar 430 is basically a spring that is a spring that can be relaxed and contracted. Further, the coupling bar 430 can be formed by attaching a housing through a spring or by attaching a separate rod or the like. Both ends of the coupling bar 430 are fitted to the insertion hole 411 formed in the inner bracket 410 and the outer bracket 420 to connect the inner bracket 410 and the outer bracket 420 do. For this reason, it is needless to say that the joining bar 430 should be formed of a material having sufficient durability to absorb impact from external force according to the environmental conditions in which the storage tank 100 is located.

In addition to the above-described configuration, the coupling bar 430 may include a hinge between the spring and the spring and may be coupled through a hinge. In this case, the desired position may be freely connected from a desired position, The effect of absorbing the impact can be obtained more flexibly.

The storage tank 100 and the inner bracket 410, the coupling bar 430, the outer bracket 420 and the side frame 210 are coupled to each other. And the coupling bar 430 is positioned between the support structure 200 and the storage tank 100 and is coupled with the coupling bar 430 through the coupling bar 430. [ It is easy to come up with stadiums such as boxing and professional wrestling. The stadiums used in boxing, professional wrestling, etc. have a field where the actual competition takes place, a ring formed along the border of the field, And a joint which connects the corner of the ring and the column, respectively. In the boxing or professional wrestling competition, there are many incidents to hit the ring, and there is a technique to utilize the recoil of the ring, so that the stadium must be designed to withstand a considerable impact. And is applied to the buffer support structure of the storage tank 100.

However, since the impact is not always transmitted in the same direction, there is a need to include a means capable of supporting the impact and a means capable of dispersing the impact in various directions or accepting impact from various directions.

FIG. 3 is a side view showing one embodiment of the inner bracket and the outer bracket, and FIG. 4 is a side view showing another embodiment of the inner bracket and the outer bracket.

3 and 4, one side of the inner bracket 410 and the outer bracket 420 further includes a convexly protruding part 412, and the protruding part 412 includes at least one flat One side of the flat surface 413 includes the insertion hole 411 in which a thread is formed on the side where the embedded side is embedded and protruded from both ends of the coupling bar 430 to form a flat surface 413 are formed to be able to be attached and detached via a thread.

That is, the inner bracket 410 and the outer bracket 420 form a convexly protruding part 412. This is seen as a hemispherical shape when viewed from the outside. When the hemispherical shape is applied, the joining bar 430 can be fitted into the joining bar 430 at a more various angle than in the case of forming the insertion hole 411 in the simple plane. In addition, the protruding part 412 is provided with at least one flat surface 413, and one side of the flat surface 413 includes an insertion hole 411 in which a threaded side is formed in the recessed side. That is, if the flat surface 413 is formed at various angles and positions, one insertion hole 411 is formed in the flat surface 413, so that even if one inner bracket 410 and the outer bracket 420 are used, It becomes possible to hold the insertion hole 411 at an angle and position. If a pentagon and a hexagon constituting the surface of the soccer ball are regarded as one flat surface 413 and an insertion hole 411 is formed for each flat surface 413, It will be understood that the insertion hole 411 is formed at various angles and positions.

The coupling bar 430 can be detached from the flat surface 413 by forming a thread corresponding to the thread of the insertion hole 411 along the outer circumferential surface protruding from both ends of the coupling bar 430, So that the coupling bar 430 can absorb and mitigate the impact through the built-in spring without falling out from the insertion hole 411 even in a severe impact.

The protruding part 412 is then raised from at least one of the outer surface of the storage tank 100 and the inner surface of the side frame 210 to facilitate angle adjustment. The protruding part 412 may form a polyhedral structure in which a plurality of flat surfaces 413 are formed at different slopes. A plurality of flat surfaces 413 extending at various slopes are formed on the polyhedral structure, and one of the slopes of the various flat surfaces 413 can be selected and used as needed.

 And is further connected to the storage tank 100 and the side frame 210 through a support 440 which is raised from the inner surface of the side frame 210 and is less elastic than the protruding part 412. This is because the protruding part 412 is shaped like a mushroom and is connected via a support 440 having a small elastic modulus, so that the support 440 can absorb the impact additionally, The inner bracket 410 and the outer bracket 420 can be formed more advanced than the case including only the conventional protruding part 412. [

Fig. 5 is a cross-sectional view showing a supporting base on which a buffer layer is formed.

Referring to FIG. 5, a buffer layer 450 laminated with a soft foam material is further formed in the inner space of the support 440 to buffer vibrations applied from the outside. This buffer layer 450 also has the effect of preventing the protruding part 412 from being damaged or deformed from the impact. As a more robust structure, it is also possible to form a hexagonal columnar honeycomb structure between the buffer layers 450, or to add a separate interior material.

Referring again to FIGS. 3 and 4, the storage tank 100 and the side frame 210 are formed with a predetermined depth on one surface thereof. The inner surface of the storage tank 100 and the side frame 210 are provided with a rotation groove The support base 440 further includes a coupling protrusion 441 protruding from a position corresponding to the rotation groove 211 and coupled with the rotation groove 211 via a thread formed on the protruding outer circumferential surface do.

In this configuration, the inner bracket 410 and the outer bracket 420 can be rotated from the storage tank 100 and the side frame 210, So that the impact received by the motor 420 is sufficiently reduced. More specifically, if the coupling bar 430 is simply fixed to the inner bracket 410 and the outer bracket 420 and the storage tank 100 and the side frame 210, even if the spring is embedded, The spring has a limitation in absorbing the force due to the impact. The inner bracket 410 and the outer bracket 420 are rotated without being fixed to the storage tank 100 and the side frame 210 so that the inner bracket 410 and the outer bracket 420 are formed on the protruding part 412 of the inner bracket 410 and the outer bracket 420 The insertion hole 411 can be rotated together to move within a predetermined range so that the spring of the coupling bar 430 is partially relaxed so that a higher impact amount can be absorbed. Therefore, if the support base 440 is configured to be rotatable from the storage tank 100 and the side frame 210, the inner bracket 410 and the outer bracket 420 are rotated to have the same effect as described above. That is, the storage tank 100 and the side frame 210 are provided with rotation grooves 211 formed on the inner circumferential surface thereof with projections formed on the support table 440 at positions corresponding to the rotation grooves 211, And a coupling protrusion 441 is formed to be coupled with the rotation groove 211 through the thread. That is, since the coupling protrusions 441 are threadedly engaged with the rotation grooves 211, the inner brackets 410 and the outer brackets 420 are rotated as necessary.

With this configuration, a phenomenon in which the coupling bar 430 is pushed or broken by a strong impact can be remarkably reduced compared to the conventional art, and the rotation of the inner bracket 410 and the outer bracket 420 is utilized, 411 are not formed in the same direction in all directions, the inner bracket 410 and the outer bracket 420 can be rotated and moved to a desired position.

In addition, it is possible to reduce the formation of unnecessary insertion holes 411 through the rotation structure, and the coupling bar 430 can be configured to hold a higher impact amount according to the above description. However, , There may occur a situation in which the amount of the impact is sufficiently large that the coupling bar 430 can hold. In this case, it is necessary that the inner bracket 410 and the outer bracket 420 are fixed without being rotated from the storage tank 100 and the side frame 210. In this case, therefore, it is necessary to further form a separate fixing means.

A coupling plate 431 including at least one through hole 432 is formed at one end of the support frame 440 and a through hole 432 is formed through one side of the storage tank 100 and the side frame 210, The inner bracket 410 and the outer bracket 420 penetrate through the through hole 432 and are inserted into the fixing groove 212. The fixing groove 212 is formed at a position corresponding to the hole 432, And is coupled to either the storage tank 100 or the side frame 210 via a fastener 414 that is fixed to the side frame 210.

The coupling plate 431 is bent and extended at the end of the support 440, and is formed as a ring-like plate like a straw hat. One or more through holes 432 are formed in the coupling plate 431. One side of the storage tank 100 and the side frame 210 is further provided with a fixing groove 212 which is embedded at a position corresponding to the through hole 432 and in which an inner circumferential surface is threaded. The through holes 432 of the engaging plate 431 formed on the inner bracket 410 and the outer bracket 420 are aligned with the fixing grooves 212 of the storage tank 100 and the side frame 210, A fastener 414, which is a locking means such as a nut, or the like, it is no longer rotated, and the joining bar 430 is stably inserted and fixed.

As described above, the construction and function of the buffer support structure of the storage tank according to the present invention are described in the above description and drawings, but the description of the present invention is not limited to the above description and drawings, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention.
