[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-4 The light box profile structure shown includes:

[0030] A first profile 1 is connected to a second profile 2 at its bottom. The first profile 1 has a mounting groove 3 inside, and a power supply box 4 for providing power to the light box is provided inside the mounting groove 3. A top cover 5 is rotatably connected to one end of the second profile 2. The top cover 5 is arc-shaped and has a rotating groove 6 at one end. A rotating block 7 is connected to one side of the top of the second profile 2, and a slot 8 is provided inside the rotating block 7. A circular block 9 is connected to one side of the slot 8. By inserting one end of the top cover 5 into the slot 8 and inserting the circular block 9 into the rotating groove 6 of the top cover 5, one end of the top cover 5 can rotate around the circular block 9 as the center point.

[0031] Spring 10, which is disposed inside the upper cover 5, is used to clamp and fix the upper cover 5 to the top of the second profile 2 by its own elastic force;

[0032] The first heat dissipation groove 11 is arranged in the second profile 2, and a second heat dissipation groove 17 is arranged at the top of the first heat dissipation groove 11, which is used for dissipating the heat generated by the power box 4.

[0033] The rotating block 7 is provided with a first clamping groove 12, one end of the upper cover 5 is provided with a second clamping groove 13, and the two ends of the elastic sheet 10 are respectively inserted into the first clamping groove 12 and the second clamping groove 13. When the two ends of the elastic sheet 10 are respectively inserted into the first clamping groove 12 in the rotating block 7 and the second clamping groove 13 at one end of the upper cover 5, the elastic sheet 10 will be elastically deformed, and the elastic force of the elastic sheet 10 will make the upper cover 5 tightly clamped and fixed on the top of the second profile 2 when the upper cover 5 is closed.

[0034] The top of the second profile 2 is connected with a support plate 14, and the top of the support plate 14 is connected with a pad plate 15. One end of the upper cover 5 is connected with a plurality of convex strips 16. The convex strips 16 are in contact with the pad plate 15 after the upper cover 5 is rotated. The support plate 14 and the pad plate 15 provide stable support for the upper cover 5. When the upper cover 5 is closed, the convex strips 16 at one end of the upper cover 5 are in contact with the pad plate 15, which increases the contact area and friction between the upper cover 5 and the second profile 2.

[0035] The first heat dissipation groove 11 and the second heat dissipation groove 17 are both provided with a sliding groove 18. The top of the sliding groove 18 is connected with a limiting strip 19. The surface of the sliding groove 18 in the second heat dissipation groove 17 is slidingly connected with a pull block 20. The pull block 20 is in a T-shaped structure, and one end of the pull block 20 is connected with a pull ring 21. When assembling the lamp box profile, the pull block 20 can connect different profiles. The pull block 20 can slide in the sliding groove 18 of the profile, slide to the appropriate position, and then be connected with the pull ring 21 on another profile through the pull ring 21, so as to firmly connect the two profiles together.

[0036] The surface of the power box 4 is connected with a power line 22 for connecting with the lamp box.

[0037] The bottom of the second profile 2 is provided with an angle code groove 23. The angle code groove 23 can be installed with an angle code, so that multiple lamp box profiles can be connected through the angle code to form a stable lamp box overall frame structure.

[0038] The first profile 1, the second profile 2, the upper cover 5, and the pull block 20 are all made of aluminum alloy. The density of aluminum alloy is relatively low, which can significantly reduce the overall weight of the lamp box. The lighter weight makes it easier for the installer to operate.

[0039] The light box profile structure is assembled as follows: firstly, the power box 4 is placed in the mounting groove 3 of the first profile 1, the power cord 22 of the power box 4 is electrically connected with the light box, then one end of the upper cover 5 is aligned with the rotating block 7 at the top of the second profile 2, the one end of the upper cover 5 is inserted into the insertion slot 8 of the rotating block 7, and the circular block 9 is accurately inserted into the rotating groove 6 of the upper cover 5, at this time, the upper cover 5 can rotate around the circular block 9 as the center point to realize the rotation opening and closing of the upper cover 5, then the two ends of the elastic sheet 10 are respectively inserted into the first clamping groove 12 in the rotating block 7 and the second clamping groove 13 at one end of the upper cover 5, the upper cover 5 is clamped and fixed at the top of the second profile 2 by the elastic force of the elastic sheet 10, the installation of the upper cover 5 is completed, and according to the needs, the light box profile can be connected with other profiles by using the corner code and other connecting pieces through the corner code groove 23 at the bottom of the second profile 2 to complete the assembly of the whole light box profile structure.

[0040] When the upper cover 5 needs to be disassembled, the elastic sheet 10 is pulled out of the first clamping groove 12 and the second clamping groove 13 by overcoming the elastic force of the elastic sheet 10, and the upper cover 5 can be easily taken off, the operation is relatively convenient, and the maintenance time and cost are reduced.

[0041] When the power box 4 generates heat, the heat is firstly transmitted to the second profile 2, due to the existence of the first heat dissipation groove 11 and the second heat dissipation groove 17, the heat makes the air in the heat dissipation groove rise to form natural convection, the external air enters from the first heat dissipation groove 11 and the second heat dissipation groove 17, flows along the heat dissipation groove, carries away the heat of the power box 4 absorbed by the second profile 2 and discharges, and the heat dissipation is realized.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
