In addition, as shown in FIG. 6 , both ends of the band shape are bent to protect the cable 130 drawn out from the cable release hole 11 at a certain point of the moving bar 50 , so that approximately “┏┓” A protective frame 60 having a shape is installed and provided.

The shock-up shock bar 70 is provided with a pair of members with both ends coupled to both sides of the protrusion 42 of the moving member 40 and the protrusion 58 provided on the lower side of the moving bar 50 . is configured, and is provided to prevent arbitrary flow of the moving bar 50 while being operated by an external force exceeding a certain value while being parallel to each other with the pair of moving bars 50 .

At this time, as the moving member 40 to which one end of the pair of shock absorbers 70 is fixed is selectively raised or lowered between the upper plate 20 and the lower plate 22, the shock absorber 70 The available load can be varied. Since the configuration and operation of the shock absorber 70 is a known technique in the art, a more detailed description will be omitted.

In the second frame 30, in a state in which a pair of side plates 32 having a substantially right-angled triangular shape are arranged to be spaced apart from each other by a predetermined interval, along the inclined surface of the second frame 30, an approximately square plate-shaped inclined plate 34 is fixedly coupled, A rotation shaft 33 fixedly coupled to the other end of the pair of moving bars 50 is installed and configured through the coupling hole 32a formed at the upper vertex of the pair of side plates 32 .

In addition, a lower cover installation hole 32b to which an end of the lower cover 82 is coupled is formed at a point adjacent to one vertex of the lower end of the pair of side plates 32, and the lower cover of the outer surface of each side plate 32 In the vicinity of the installation hole (32b), a guide groove (35) serving as a stopper to limit the movement range of the lower cover (82) interlocked with the moving bar (50) is formed in a stepped shape.

In addition, a corner member 36 is covered at a certain point on the upper side of the second frame 30 adjacent to the upper vertex portion of the pair of side plates 32, and the lower corner cover 37 is covered on the lower corner portion. done so as to

And, as shown in FIGS. 7 and 8A and 8B , the second frame 30 is fixedly coupled to the upper side of the manipulation panel side connector 210 , so that the corresponding manipulation panel 200 is moved to the second It is configured to maintain a suspended state on the lower side of the frame 30. At this time, a height adjusting screw 39 whose fastening depth is adjusted through a predetermined hexagon wrench is fastened to each corner of the upper surface of the manipulation panel side connector 210. In addition, a height adjustment groove 38 is formed in a concave shape in a shape corresponding to the head of the height adjustment screw 39 on the lower surface of the second frame 30 .

Accordingly, by selectively adjusting the height of the height adjustment screw 39 to adjust the insertion depth into the height adjustment groove 38, the operation panel is installed via the operation panel side connector 210 ( 200) can be adjusted.

In a state in which a pair of moving bars 50 and shock-up shock absorbers 70 are installed between the first frame 10 and the second frame 30, the first frame 10 and the second frame 30 ) between each other, the upper cover 80 and the lower cover 82, each of which has a "┏┓" shape or a "┗┛" shape, is installed, and the lift arm is configured to form an appearance of a substantially rectangular bar shape. do.

At this time, between the periphery of the lower cover installation holes 14b and 32b of the first frame 10 and the second frame 20 and the inner wall surface of the lower cover 82, a hole is perforated in the center of a substantially disc shape. The plastic tension auxiliary members 14c and 32c are inserted and provided.

When the operation panel 200 associated with the lift arm is raised or lowered, an arbitrary recoil is generated due to the characteristics of the shock-up shock absorber 70, and the operation panel 200 deviates from the position the operator wants to stop. There is a risk of soaring upward or falling, and by inserting the tension auxiliary members 14c and 32c made of the plastic material to provide a cushioning function, it is possible to solve the above-described problems.

Next, the operation of the present invention made as described above will be described with reference to the drawings.

That is, as shown in FIG. 9 , in a state in which one end of the lift arm associated with a predetermined equipment side has a rotatable structure, the other end of the lift arm associated with the operation panel 200 of the equipment is inclined at a certain level by an external force. As it rises or descends so as to have a , the height of the operation panel 200 can be adjusted in an optimal state according to the working environment.

At this time, the available load required to raise or lower the operation panel 200 is selectively raised or lowered by the movable member 40 serving as a tension bolt using a predetermined tool, so that the pair of shock-up shock absorbers ( The position of one end of the 70) can be varied as it rises or descends in conjunction, and through this, it is possible to optimize the available load according to the usage environment of the corresponding operation panel 200 .

In addition, the operating angle range of the lift arm formed according to the rising or falling of the other end from the horizontal state of the lift arm is determined by the angle adjusting screw 56 mounted on the angle adjusting bracket 54 of the moving bar 50 . It can be adjusted through operation.

That is, as the angle adjusting screw 56 is selectively moved forward and backward through a predetermined tool, the end side of the angle adjusting screw 56 to which the plastic cap 57 is fastened and the first frame 10 ) or the position where the second frame 30 abuts is adjusted, the lifting or lowering position of the lift arm can be limited.

In an embodiment of the present invention, it is preferable that the angle formed by the lift arm according to the rise and fall of the other end of the lift arm is adjustable within a range of 40°, respectively, based on the horizontal state.

In addition, when the lift arm is operated, a space in which the inside is exposed is generated around the upper cover 80 and the lower cover 83 assembled with the first frame 10 and the second frame 30, As the area of the corresponding space is changed according to the operation of the lift arm, a problem may occur that foreign substances are arbitrarily introduced into the lift arm through the corresponding space. For this purpose, by mounting the upper cover 18, the lower cover 19, the corner cover 36, and the lower corner cover 37 in the corresponding space, arbitrary inflow of foreign substances into the lift arm can be prevented. .

In addition, guide grooves 16 and 35 for performing a stopper function are formed on the outer surfaces of the side plates 14 and 32 of the first frame 10 and the second frame 20 corresponding to both ends of the lower cover 82 . As a result, when the other end of the lift arm is raised or lowered, excessive rise or fall outside the set angle range can be suppressed.

Therefore, through the lift arm for the operation panel having a height adjustment function in the present invention, the operator can adjust the height of the operation panel 200 provided on one side of the predetermined equipment according to the use environment through the lift arm having a specific structure. It can be easily adjusted, and through this, the operator can perform work more efficiently in an optimal environment.
