[0035] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0036] An embodiment of the present application discloses a light box display cabinet.

[0037] Embodiment 1

[0038] Referring to Figure 1 , a light box display cabinet includes a cabinet bottom plate 1. The bottom of the glass cover 11 is fixedly connected to the top of the cabinet bottom plate 1 for protecting the displayed items. The bottom of the light box 12 is fixedly connected to the top of the cabinet bottom plate 1, and the light emitted by the light box 12 passes through the glass cover 11 to facilitate the observation of the displayed items. A lifting mechanism 2 is provided at the bottom of the cabinet bottom plate 1.

[0039] Through the above arrangement, the staff places the glass cover 11 on the top of the cabinet bottom plate 1 and fixes it for display.

[0040] Referring to Figure 2 , as shown in Figure 3, the lifting mechanism 2 includes an upper connecting rod 23. A circular hole 1 is provided on the side wall of one end of the upper connecting rod 23 away from the horizontal connecting rod 22. The central control rod 26 horizontally penetrates through the circular hole 1, so that the upper connecting rod 23 is rotatably connected to the central control rod 26. A through hole 1 is provided on the side wall of one side of the lower connecting rod 27 close to the central control rod 26. The central control rod 26 horizontally penetrates through the through hole 1, so that the central control rod 26 is rotatably connected to the lower connecting rod 27. The lifting mechanism 2 further includes a bottom connecting block 21 fixedly connected to the bottom of the cabinet bottom plate 1. A circular hole 2 is provided on the side wall of the bottom connecting block 21. The horizontal connecting rod 22 horizontally penetrates through the circular hole 2, so that the horizontal connecting rod 22 is rotatably connected to the bottom connecting block 21. A circular hole 3 is provided on the side wall of one side of the upper connecting rod 23 close to the horizontal connecting rod 22. The horizontal connecting rod 22 horizontally penetrates through the circular hole 3, so that the upper connecting rod 23 is rotatably connected to the horizontal connecting rod 22. Both ends of the horizontal connecting rod 22 are fixedly connected to one side of the limiting disc 24 close to the horizontal connecting rod 22. A through sliding groove is provided on the side wall of the vertical limiting plate 25. The side wall of the horizontal connecting rod 22 between the upper connecting rod 23 and the limiting disc 24 movably penetrates through the through sliding groove provided on the side wall of the vertical limiting plate 25, so that the horizontal connecting rod 22 is slidably connected to the vertical limiting plate 25.

[0041] Through the above arrangement, when the bidirectional lead screw 29 rotates, the two central moving blocks 28 will be controlled by the rotation of the bidirectional lead screw 29 to move in opposite directions. When the central moving block 28 moves horizontally, the central moving block 28 will drive the central control rod 26 to move horizontally synchronously.

[0042] Referring to Figure 2, 3, the other end of the central control rod 26 away from the upper end link 23 is fixedly connected to one side of the central moving block 28 close to the central control rod 26, so as to facilitate the central moving block 28 to drive the central control rod 26 to move horizontally. A through internal threaded hole is provided in the middle side wall of the central moving block 28, and the bidirectional lead screw 29 is threaded through the through internal threaded hole provided in the middle side wall of the central moving block 28, so that the bidirectional lead screw 29 is threadedly connected to the central moving block 28. Both ends of the bidirectional lead screw 29 are fixedly connected to one side of the limit disc 210 close to the bidirectional lead screw 29, so as to ensure that the bidirectional lead screw 29 is always threadedly connected to the central moving block 28 through the limit of the limit disc 210. The side of the limit disc 210 away from the bidirectional lead screw 29 is fixedly connected to one end of the driving rod 211 close to the limit disc 210, so that the driving rod 211 can drive the limit disc 210 to rotate. The side wall of the driving rod 211 away from the limit disc 210 is fixedly connected to the bottom connection end of the grip 212, so as to facilitate the staff to drive the whole mechanism through the grip 212.

[0043] With the above settings, the staff grasps the grip 212 and drives the driving rod 211 to rotate through the grip 212. The driving rod 211 will drive the limit disc 210 to rotate, and the limit disc 210 will drive the bidirectional lead screw 29 to rotate.

[0044] Refer to Figure 4 , a circular hole four is provided in the side wall of the end of the lower end link 27 away from the central control rod 26, and the bottom short shaft 213 horizontally penetrates through the circular hole four, so that the bottom short shaft 213 is rotatably connected to the lower end link 27, so as to facilitate the rotation of the lower end link 27. A circular through hole is provided in the side wall of the connecting member 214, and the side of the bottom short shaft 213 away from the lower end link 27 is fixedly penetrated through the circular through hole provided in the side wall of the connecting member 214, so that the bottom short shaft 213 is fixedly connected to the connecting member 214. The bottom of the connecting member 214 is fixedly connected to the top of the mechanism bottom plate 215. The side wall of the vertical limiting plate 25 close to the mechanism bottom plate 215 is fixedly connected to the side wall of the mechanism bottom plate 215 close to the vertical limiting plate 25, so that the structural integrity is stronger. The bottom of the mechanism bottom plate 215 is fixedly connected to the top connection end of the roller 216, so as to facilitate the user to push the whole structure through the roller 216 more conveniently.

[0045] With the above settings, when the central control rod 26 moves horizontally, the lower connecting rod 27 and the upper connecting rod 23 gradually change from an inclined state to a vertical state, so that the distance between the bottom connecting block 21 and the connecting member 214 increases. The lower connecting rod 27 will push the horizontal connecting rod 22 to move vertically upward. The horizontal connecting rod 22 will drive the bottom connecting block 21 to move vertically upward. The bottom connecting block 21 will drive the cabinet bottom plate 1 to move vertically upward. The cabinet bottom plate 1 will lift the glass cover 11 and the light box 12 located on the top of the cabinet bottom plate 1, thereby lifting the display content. When it is lifted to the top, the horizontal connecting rod 22 will slide to the top of the sliding groove on the side wall of the limit disk 24.

[0046] Among them, the light box 12 is a prior art, and its structural principle will not be described in detail.

[0047] The implementation principle of a light box display cabinet in an embodiment of the present application is as follows:

[0048] The staff rotates the grip 212, and the grip 212 drives the limit disk 210 to rotate. The limit disk 210 will drive the bidirectional lead screw 29 to rotate. The bidirectional lead screw 29 will drive the central moving block 28 to move horizontally, thereby driving the lower connecting rod 27 and the upper connecting rod 23 to gradually change from an inclined state to a vertical state, so that the cabinet bottom plate 1 moves upward, thereby lifting the glass cover 11 and the light box 12.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
