[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] In the current display technology, the light box of the LED display is usually frame-type, often square, long or round. The round frame light box is not easy to maintain and install due to its large size, simple structure, or even one-piece molding, and has great limitations.

[0032] In order to solve the above problems, the utility model provides a light box. Figures 1 to 6 This is a specific embodiment of the light box provided by the utility model.

[0033] Reference Figures 1 to 4 The light box comprises a box body 1, a mounting bracket 2 arranged in the box body 1, and a slide rail assembly 3 arranged on the mounting bracket 2;

[0034] The box body 1 is used to accommodate the function control module. The box body 1 is provided with an opening 11 corresponding to the function control module. The function control module is arranged on the slide rail assembly 3. The slide rail assembly 3 is used to transplant the function control module through the opening 11.

[0035] The slide rail assembly 3 includes a plurality of slide rail units 31 nested in sequence, and two adjacent slide rail units 31 are slidably connected to each other.

[0036] The slide rail assembly 3 of the utility model includes a plurality of slide rail monomers 31, and two adjacent slide rail monomers 31 are movably connected so that the slide rail monomers 31 can be retracted. When the slide rail monomers 31 are retracted, the function control module 5 can be moved horizontally. When the plurality of slide rail monomers 31 are extended, the function control module 5 can be moved through the opening 11 so that the function control module 5 is moved outside the light box. The side maintenance of the function control module 5 can be realized without disassembling the light box, which has the advantage of easy maintenance.

[0037] Among them, the functional control module 5 includes a control box assembly and a control element arranged in the control box assembly, the control box assembly includes a control box and a box cover covering the control box, the box cover is connected to the control box through a hinge, and the box cover and the control box are locked by a triangular lock.

[0038] See also Figure 5The outer slide rail 31 of the two adjacent slide rail units 31 is an outer slide rail 32, and the inner slide rail 31 is an inner slide rail 33. The inner side surface of the outer slide rail 32 is provided with a first limiting structure 34, and the outer side surface of the inner slide rail 33 is provided with a second limiting structure 35 that cooperates with the first limiting structure 34. The first limiting structure 34 and the second limiting structure 35 function to limit the excessive displacement of the inner slide rail 33 relative to the outer slide rail 32, so as to prevent the inner slide rail 33 from being separated from the outer slide rail 32. Optionally, the first limiting structure 34 is a first protrusion provided on the inner sides of the outer slide rail 32, and the first protrusion is located at an end of the outer slide rail 32 close to the opening 11; the second limiting structure 35 is a second protrusion provided on the outer sides of the inner slide rail 33, and the second protrusion is located at an end of the inner slide rail 33 away from the opening 11; the first protrusion and the second protrusion at least partially overlap in the length direction of the inner slide rail 33, so that the second protrusion can be blocked by the first protrusion to block the inner slide rail 33.

[0039] For further information, see Figure 6 The inner side surface of the outer slide rail 32 is provided with a first arc-shaped groove 36 extending along the length direction of the outer slide rail 32, and the outer side surface of the inner slide rail 33 is provided with a second arc-shaped groove 37 corresponding to the first arc-shaped groove 36. The first arc-shaped groove 36 is used to enclose a cylindrical cavity with the second arc-shaped groove 37, and a plurality of steel balls 38 are arranged in the cylindrical cavity. The sliding friction between the inner slide rail 33 and the outer slide rail 32 can be reduced by the steel balls 38. The first arc-shaped groove 36 can be formed by a concave setting of the inner side wall of the outer slide rail 32, or by bending the side wall of the outer slide rail 32.

[0040] See also Figure 4 The number of the slide rail monomers 31 is determined according to the distance that the slide rail assembly 3 needs to transfer the functional control module 5. The number can be moderate, not too much or too little. If the number of the slide rail monomers 31 is too much, it will lead to high processing costs and difficult assembly. If the number of the slide rail monomers 31 is too little, the length of a single slide rail monomer 31 is long, and the bearing capacity is large and easy to bend. Optionally, the number of the slide rail monomers 31 is set to three, and the three slide rail monomers 31 are respectively the first slide rail, the second slide rail and the third slide rail. The first slide rail is sleeved on the outside of the second slide rail, and the second slide rail is sleeved on the outside of the third slide rail.

[0041] Specifically, the sum of the length of the second slide rail extending from the first slide rail and the length of the third slide rail extending from the second slide rail is greater than the distance between the side of the function control module away from the opening 11 and the opening 11. This arrangement ensures that after the second slide rail and the third slide rail are extended, the function control module 5 can be moved out of the opening 11, which is convenient for user maintenance.

[0042] Optionally, the third slide rail is arranged flush with the lower side wall of the opening 11. When the third slide rail transfers the function control module 5 through the opening 11, the torque borne by the second slide rail and the third slide rail is the largest. This arrangement allows the third slide rail to be placed on the lower side wall of the opening 11, thereby preventing the second slide rail and the third slide rail from being bent.

[0043] The function control module 5 is mounted on the third slide rail, and the third slide rail is connected to the function control module 5 by screws. Specifically, a first screw hole is provided on the bottom surface of the control box, and a first countersunk hole corresponding to the first screw hole is provided on the third slide rail. The screw passes through the first countersunk hole and is connected to the first screw hole, thereby fixing the control box and the third slide rail together.

[0044] For details, see Figures 1 to 3 The mounting bracket 2 includes two legs 21 arranged in parallel and a support plate 22 arranged on the legs 21, and the support plate 22 extends in the same direction as the slide rail unit 31. The lower side wall of the box body 1 is provided with a first heat dissipation hole 12 corresponding to the function control module 5. The legs 21 are composed of three straight plates, and the three straight plates are connected to form a U-shaped leg 21. After the U-shaped leg 21 is inverted and installed inside the box body 1, the lower side wall of the box body 1 still has a large free space, so that more first heat dissipation holes 12 can be provided to help the function control module 5 to dissipate heat.

[0045] The first slide rail is mounted on the support plate 22, and the first slide rail is connected to the support plate 22 by screws. Specifically, the support plate 22 is provided with a second screw hole, the first slide rail is provided with a second countersunk hole corresponding to the second screw hole, and the screw passes through the second countersunk hole and is connected to the second screw hole, thereby fixing the first slide rail to the support plate 22.

[0046] The light box further includes a cover plate 4 covering the opening 11, and the cover plate 4 and the light box are detachably arranged. By closing the opening 11 with the cover plate 4, the internal components of the light box can be protected. The cover plate 4 is detachably arranged, and when the function control module 5 needs to be maintained, the cover plate 4 can be removed to open the opening 11, which can reduce maintenance costs and time.

[0047] The cover plate 4 is provided with a second heat dissipation hole, and a dustproof plate is provided on the second heat dissipation hole. The second heat dissipation hole can effectively dissipate the heat generated inside the light box, avoid damage to the internal components of the light box due to overheating, and extend the service life of the light box. The dustproof plate can prevent dust from entering the box body 1.

[0048] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
