Description

Technical Field

[0001] This utility model relates to the field of display cabinet technology, specifically a pull-out anti-collision display cabinet. Background Technology

[0002] Display cases, as an important medium for displaying goods, cultural relics or works of art, have been widely used in various scenarios such as retail, exhibitions and museums.

[0003] Display cases are mostly fixed structures with non-adjustable heights, making it difficult to meet the comfortable viewing needs of viewers of different heights, especially in public places with high foot traffic and diverse audience groups. To address the height adjustment issue, some adjustable display cases have emerged, such as those using simple latches with different height positioning holes, or those using electric push rods for raising and lowering. However, the former is cumbersome to adjust, has limited positioning accuracy, and cannot achieve stepless adjustment; the latter suffers from complex structures, high costs, reliance on external power sources, and inconvenient maintenance. Therefore, a pull-out, impact-resistant display case is proposed to solve these problems. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 3 In this embodiment, a pull-out anti-collision display cabinet includes a base 1 and a protective frame 2. A storage frame 3 is provided on the inner side of the protective frame 2. A pull-out groove is provided on the front of the inner side of the storage frame 3, and a display panel 4 is slidably connected to the inner side of the pull-out groove. An adjustment component for audiences of different heights is provided on the right side of the base 1.

[0024] Please see Figure 1 In this embodiment, the adjustment assembly includes a transmission rod 5 rotatably connected to the right side of the base 1. A transmission wheel 6 is fixedly connected to the outer side of the transmission rod 5. A transmission belt 7 is driven to the outer surface of the transmission wheel 6. A driven wheel 8 is driven to the bottom end of the transmission belt 7. A driven rod 9 is fixedly connected to the inner side of the center of the driven wheel 8. A first bevel gear 10 is fixedly connected to the left end of the driven rod 9. A second bevel gear 11 meshes with the bottom of the first bevel gear 10. A threaded rod 12 is fixedly connected to the inner side of the center of the second bevel gear 11. A threaded cylinder 13 is threadedly connected to the outer side of the threaded rod 12.

[0025] Specifically, the outer wall of the threaded cylinder 13 is square, and the protective frame 2 is fixedly connected to the top of the threaded cylinder 13.

[0026] Specifically, a limiting port adapted to the threaded cylinder 13 is provided on the top of the inner side of the base 1, and a handwheel 501 is fixedly connected to the right end of the transmission rod 5.

[0027] It should be noted that the square outer wall of the threaded cylinder 13 mates with the square inner hole of the upper limit port of the base 1, forming an effective anti-rotation mechanism. This structure ensures that when the threaded rod 12 rotates, the threaded cylinder 13 cannot rotate accordingly.

[0028] Specifically, a bracket 14 is rotatably connected to the outside of the driven rod 9, and the bracket 14 is fixedly connected to the inner bottom wall of the base 1.

[0029] It should be noted that the bracket 14, which is fixed to the inner bottom wall of the base 1, provides a stable fulcrum for the driven rod 9 to rotate.

[0030] Specifically, a rubber pad 15 is provided between the inner wall of the protective frame 2 and the outer wall of the storage frame 3, and a handle is fixedly connected to the front of the display board 4.

[0031] It should be noted that the elastic deformation of the rubber material absorbs the impact energy that may be generated during the pulling process of the display panel 4, which plays a role in buffering and preventing collisions. The rubber pad 15 fills the gap, reduces the shaking between the protective frame 2 and the storage frame 3, and enhances the stability of the overall structure.

[0032] Specifically, metal connectors 16 are fixedly connected to the top and bottom sides of the front of the display board 4, and magnetic pieces 17 that are compatible with the metal connectors 16 are fixedly connected to the top and bottom sides of the front of the storage frame 3.

[0033] It should be noted that the metal connector 16 fixed to the front of the display panel 4 and the magnetic plate 17 fixed to the front of the storage frame 3 together constitute a magnetic locking device. When the display panel 4 is pushed back to the fully closed position, the metal connector 16 and the magnetic plate 17 enter the magnetic field, and the magnetic force generated therein can hold the display panel 4 firmly in this position, preventing it from sliding out on its own due to slight vibration or tilt of the cabinet.

[0034] Specifically, guide rods 18 are fixedly connected to the left and right sides of the bottom of the guard frame 2. Two guide holes adapted to the guide rods 18 are opened on the top of the inner side of the base 1. Anti-detachment plates 19 are fixedly connected to the bottom ends of the two guide rods 18. The two anti-detachment plates 19 are fixedly connected to the left and right sides of the threaded cylinder 13 respectively.

[0035] It should be noted that the anti-detachment plate 19 will contact the inner top wall of the base 1, thereby preventing the guide rod 18 from further disengaging from the guide hole, and also preventing the threaded cylinder 13 from detaching from the threaded rod 12.

[0036] The working principle of the above embodiments is as follows:

[0037] The handwheel 501, fixedly connected to the right end of the transmission rod 5, is manually rotated. The rotation of the handwheel 501 drives the transmission rod 5 and its transmission wheel 6 to rotate synchronously. The transmission wheel 6 transmits power to the driven wheel 8, which is connected to the bottom end of the transmission belt 7 via its outer surface. The rotation of the driven wheel 8 drives the driven rod 9, fixedly connected to its inner center, to rotate, causing the first bevel gear 10, fixedly connected to its left end, to rotate synchronously. This, in turn, drives the second bevel gear 11, which meshes with the first bevel gear 10, to rotate. The threaded rod 12 rotates together with the second bevel gear 11. The square outer wall of the threaded cylinder 13 is constrained by the upper limit opening of the base 1 and cannot rotate. Therefore, the rotational motion of the threaded rod 12 is forced into the vertical linear motion of the threaded cylinder 13 along its axis. The vertical linear motion of the threaded cylinder 13 directly pushes the protective frame 2, which is fixedly connected to its top, to rise or fall synchronously. The lifting and lowering motion of the protective frame 2 is guided by the guide mechanism formed by the guide rods 18 on the left and right sides and the guide holes on the base 1 to ensure smooth movement. When the protective frame 2, the storage frame 3 and the display board 4 are adjusted to the appropriate height, the handwheel 501 is stopped.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
