[0023] 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.

[0024] Please see Figure 1-3This utility model provides a signage light box that facilitates the replacement of display signs, including a box body 1 and a transparent plate 2 hinged to the front of the box body 1;

[0025] Several lighting lamps 3 are installed inside the housing 1;

[0026] Two clamping components 4 are respectively set on both sides of the inner cavity of the box 1 and penetrate through the bottom of the box 1;

[0027] Slide 5 is located at the bottom of housing 1;

[0028] Connector 6 is located at the bottom of transparent plate 2 and can slide in groove 5;

[0029] Fastener 7 is located at the bottom of housing 1;

[0030] The fastener 7 is used to fix the connector 6 and the transparent plate 2. The connector 6 is used to limit and guide the unfolded transparent plate 2. The two clamping parts 4 are used to clamp and fix the two sides of the display board respectively.

[0031] Specifically, refer to Figure 2 The clamping component 4 includes a clamping plate 41 disposed on one side inside the housing 1; a clamping plate 42 slidably penetrating the bottom of the housing 1; two support frames 43 respectively disposed at the bottom of the housing 1; and threaded rods 44 rotatably penetrating the two support frames 43 at both ends, with the clamping plate 42 threadedly sleeved on the outer wall of the threaded rods 44.

[0032] In this embodiment, when the threaded rod 44 is rotated, the clamping plate 42 slides up and down along the threaded rod 44 and cooperates with the clamping plate 41 to clamp and fix the two sides of the display board.

[0033] Specifically, refer to Figure 2 The connector 6 includes a sliding shaft 61 that is slidably disposed in the slide groove 5; a rotating shaft 62 disposed at the bottom of the transparent plate 2; and a connecting rod 63 whose two ends are respectively rotatably sleeved on the outer walls of the sliding shaft 61 and the rotating shaft 62.

[0034] In this embodiment, when the transparent plate 2 is unfolded or closed, the sliding shaft 61 slides in the sliding groove 5, and the connecting rod 63 plays a limiting and guiding role to ensure that the transparent plate 2 moves smoothly.

[0035] Specifically, refer to Figure 3 The fixing component 7 includes a fixing plate 71 disposed at the bottom of the housing 1; two slide rods 72 respectively disposed on both sides of the fixing plate 71; two stops 73 respectively disposed on opposite sides of the two slide rods 72; a clamping frame 74 slidably sleeved on the outer wall of the slide rods 72; and a spring 75 sleeved on the outer wall of the slide rods 72 and connected at both ends to the outer walls of the stops 73 and the clamping frame 74 respectively.

[0036] In this embodiment, when the transparent plate 2 is closed, the two clamping frames 74 can clamp and fix the sliding shaft 61, thereby fixing the connector 6 and the transparent plate 2 to ensure that the light box is closed and stable.

[0037] Specifically, refer to Figure 2 A limiting groove 8 is provided on the top wall of the inner cavity of the housing 1, and a limiting block 9 is provided on the top of the clamping plate 42 and can slide in the limiting groove 8.

[0038] In this embodiment, the sliding fit between the limiting block 9 and the limiting groove 8 prevents the clamping plate 42 from rotating with the threaded rod 44, ensuring its linear lifting and lowering and improving clamping stability.

[0039] Specifically, refer to Figure 2 Rubber pads 10 are provided on opposite sides of clamping plate 41 and clamping plate 42. On the one hand, they increase friction to prevent the display board from sliding, and on the other hand, they prevent scratches on the surface of the display board during clamping, thus playing a protective role.

[0040] Working principle

[0041] When replacing the display panel, first operate the fixing component 7 to overcome the elastic force of the spring 75 and slide the clamping frame 74 to both sides to loosen the fixing of the connecting component 6. Then pull open the transparent plate 2. The transparent plate 2 rotates through the hinge, and at the same time, the sliding shaft 61 of the connecting component 6 slides in the sliding groove 5. The connecting rod 63 guides the transparent plate 2 to unfold smoothly. Next, rotate the threaded rod 44 to make the clamping plate 2 42 rise along the threaded rod 44, loosening the clamping of the display panel. Take out the old display panel and put in the new display panel. Then rotate the threaded rod 44 in the opposite direction, and the clamping plate 2 42 descends and cooperates with the clamping plate 1 41 to clamp the display panel through the rubber pad 10. Finally, close the transparent plate 2. The sliding shaft 61 slides in the opposite direction in the sliding groove 5. When the transparent plate 2 is completely closed, the spring 75 pushes the clamping frame 74 to reset, fixing the connecting component 6 and the transparent plate 2, completing the display panel replacement.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
