Description

Installation structure of fall-proof LED display

technical field

The invention relates to the technical field of LED display screens, in particular to an installation structure of an LED display screen that can prevent falling.

Background technique

When installing the LED display, its safety, reliability and ease of maintenance should be considered.

There are two main ways to install the known LED display module. The first one is: the light panel module that fixes the LED display screen is installed with screws, the bottom case is provided with a nut, and the box is provided with allowable screws. Through the through hole, the light panel module is fixed from the back of the box by screws.

FIG. 5( a ) is a partial schematic diagram of the installation structure of the drop-proof LED display screen, FIG. 5( b ) is a schematic diagram of the first restriction pin 41 , and FIG. 5( c ) is a schematic diagram of the installation cover plate 13 , please refer to FIG. 5 (a), FIG. 5(b), FIG. 5(c), and with continued reference to FIG. 4, the following describes the installation structure of the drop-proof LED display screen that prevents the light panel module 20 from falling through the first restricting portion 40. illustrate.

As mentioned above, the first restricting portion 40 includes the first restricting pin 41 , the light panel module 20 is provided with the first accommodating portion 21 , and the first restricting pin 41 is slidably inserted into the first accommodating portion 21 or slidably removed from the first accommodating portion 21 . Section 21 retracts. The first restricting pin 41 may be slidably mounted on the box body 10 by any known means. After the light panel module 20 is installed on the box body 10 , the first accommodating portion 21 is opposite to the first restricting pin 41 in the Y direction. In an optional embodiment, the box body 10 is provided with a first guide portion 113 , and the first restriction pin 41 is at least partially disposed in the first guide portion 113 and is slidable in the first guide portion 113 . Specifically, the first guide portion 113 may be a first guide hole provided through the side wall 11b of the first support column 11 , that is, the first guide hole serving as the first guide portion 113 communicates with the first mounting hole 111 , and the first restriction pin The front end of 41 is slidably installed on the side wall 11b of the first support column 11 along the radial direction (Y direction) of the first support column 11 , and the first accommodating portion 21 is arranged on the first installation of the light panel module 20 . On the convex portion 22, when the first mounting convex portion 22 is inserted into the first mounting hole 111, the first restricting pin 41 can be pressed to slide toward the outer side in the radial direction of the first support column 11 (ie, the reverse direction of the Y direction) to The light panel module 20 can be installed on the box body 10. After the light panel module 20 is installed on the box body 10, the first accommodating portion 21 is accommodated in the first mounting hole 111 and communicates with the first guide portion 113. The first accommodating portion 21 is opposite to the first restricting pin 41 in the Y direction. At this time, the first restricting pin 41 can slide toward the inner side (Y direction) in the radial direction of the first support column 11 and be inserted into the first accommodating portion 21 , and restrict the first mounting protrusion 22 from the first mounting hole 111 . Disengagement means the movement of the first mounting convex portion 22 in the Z direction, so that the disassembly of the light panel module 20 can be restricted.

As described above, when the first mounting protrusion 22 is inserted into the first mounting hole 111 , the first restriction pin 41 can be pressed to slide toward the outer side in the radial direction of the first support column 11 , that is, the first mounting protrusion 22 can be driven The first restriction pin 41 slides. In an optional embodiment, the first restriction pin 41 includes a first segment 411 inserted into the first accommodating portion 21 , the first segment 411 is located at the front end of the first restriction pin 41 , and the first segment 411 is provided There is a first guide surface 411a in the shape of a hemisphere, an arc, or a slope. In the initial state, the first segment 411 passes through the first guide portion 113 and is exposed in the first installation hole 111, and the first installation protrusion 22 is inserted When reaching the first mounting hole 111 , the first mounting protrusion 22 presses against the first segment 411 and slides along the first guide surface 411 a of the first segment 411 . When the first restricting pin 41 is retracted toward the first guide portion 113 as a whole, when the first accommodating portion 21 is opposed to the first guide portion 113, since the first mounting convex portion 22 no longer presses the first segment portion 411, therefore, The first restricting pin 41 protrudes from the first guide portion 113 again and is inserted into the first accommodating portion 21 . The shape of the first accommodating portion 21 is a concave shape that matches the shape of the first segment portion 411 . For example, when the first segment portion 411 is hemispherical, the first accommodating portion 21 also has a hemispherical concave shape; When the arc shape or the inclined plane is used, the first accommodating part 21 also has an arc or inclined concave shape.

In this embodiment, the first restriction pin 41 is retracted by the pressing of the first mounting protrusion 22 . As for the protruding of the first mounting convex portion 22 from the first guide portion 113 , for example, a spring mechanism can be provided to make the first restriction pin 41 protrude from the first guide portion 113 . In an optional embodiment, the first restricting portion 40 further includes a second spring 42 , and the second spring 42 drives the first restricting pin 41 to be slidably inserted into the first accommodating portion 21 . The second spring 42 is nested on the first restricting pin 41 , one end of the second spring 42 abuts on the first restricting pin 41 , and the other end abuts on the box body 10 . In the installed state, the second spring 42 can push the first restriction pin 41 and expose the first segment 411 in the first installation hole 111 . The first restricting pin 41 is retracted, but when the position of the first accommodating portion 21 is opposite to the position of the first guide portion 113, the first restricting pin 41 can automatically extend under the action of the second spring 42 and insert into the first accommodating portion 21 . Here, when the light panel module 20 is installed on the box body 10 , the installation stroke of the light panel module 20 relative to the first restricting portion 41 is usually long. During this process, the light panel module 20 can pass through the The weight and the dynamic potential energy generated when the light panel module 20 is installed can easily retract the first restriction pin 41, which is convenient for the installation of the light panel module 20. A section 411 has been inserted into the first accommodating portion 21 of the first mounting convex portion 22. Compared with the first restricting portion 40, the light panel module 2 has a very short movable stroke, so it is difficult to make the first restricting pin 41 is retracted. Therefore, the first restricting portion 40 has a very obvious effect on preventing the light panel module 20 from falling, and can prevent the light panel module 20 from accidentally falling. In addition, when the output force of the second spring 42 is adjusted (eg, the wire diameter of the second spring 42 is increased), the force with which the first restriction pin 41 is inserted into the first accommodating portion 21 can be further increased.

In order to firmly support the first restricting pin 41 , the box body 10 may be provided with a second supporting column 12 beside the first supporting column 11 , and the second supporting column 12 is provided with a first guide as the first guiding portion 113 . The holes are coaxial with the second guide hole 121 , the front end portion (including the first segment portion 411 ) of the first restriction pin 41 slides in the first guide portion 113 , and the rear end portion of the first restriction pin 41 is in the second guide hole 121 Slide inside. In addition, in order to facilitate the disassembly of the first restriction pin 41 , an installation cover 13 for installing the first restriction pin 41 may also be included. The installation cover 13 is installed on the second support column 12 and extends to the first support column 11 . superior. The front end of the mounting cover 13 is provided with a semicircular first opening 131 , and a semicircular second opening 131 with the same radius as the first opening 131 is formed on the side wall 11b of the upper end surface 11a of the first support column 11 . The opening 113a, when the installation cover 13 is installed on the second support column 12, the first opening 131 and the second opening 113a together form a first guide hole with a closed cross-section, and the second guide hole 121 can also be used in the same way form. Therefore, after the installation cover 13 is removed, the first restricting pin 41 is easily detached from the first support column 11 and the second support column 12, and the disassembly is very convenient.

The structure of releasing the restriction on the light panel module 20 by the first restricting portion 40 by the releasing portion 50 will be described in detail below.

The front of the light panel module 20 is provided with a first through hole 23 (refer to FIG. 3(a) for auxiliary purposes). The positions of the first through hole 23 and the first restricting portion 40 can be pre-designed, as long as the first through hole 23 can be The first through hole 23 and the first restriction portion 40 may be disposed at any position of the LED display screen without passing through some PCB boards of the light board 201 and the LED lighting units. The first through hole 23 communicates with the first restricting portion 40 , the releasing portion 50 includes a rod-shaped first driving member 51 , and the first driving member 51 can abut the first restricting pin 41 through the first through hole 23 . 50 , the first restricting pin 41 is retracted from the first accommodating portion 21 through the first driving member 51 , thereby releasing the restriction on the light panel module 20 by the first restricting portion 40 . By opening the first through hole 23 on the top of the light panel module 20, it is convenient for the release part 50 to release the restriction on the light panel module 20 by the first restriction part 40 from the front surface 20a of the LED display screen, and the disassembly is very convenient. In an optional embodiment, the first restricting pin 41 is provided with a first inclined portion 412 , the first driving member 51 abuts the first inclined portion 412 through the first through hole 23 , and can be positioned on the first inclined portion 412 Sliding upward, thereby pressing the first inclined portion 412 and retracting the first restricting pin 41 . After the first restricting portion 40 is retracted, the light panel module 20 can be disassembled. In addition, it should be noted that, here, the release portion 50 is a detachable component relative to the light panel module 20, such as a screwdriver, which does not need to remain on the light panel module 20, and only needs to be removed from the release portion 50 during disassembly. It only needs to pass through the first through hole 23 and abut the first restricting portion 40 and be released.
