Description

Technical Field

[0001] The utility model relates to the technical field of automatic opening and closing devices for display cabinets, in particular to an automatic opening and closing device for display cabinets with a protective structure. Background Art

[0002] The exhibition cabinet is a protective display stand for merchandise display. It not only protects the exhibits, but also presents them to the audience in an appropriate way. Through reasonable layout and lighting design, the display cabinet can highlight the characteristics of the exhibits and enhance the audience's viewing experience.

[0003] The existing announcement number is: CN 215761114 U, which discloses an automatic door opening and closing mechanism, which pushes the driving rod to slide to the right. When the teeth of the incomplete gear are engaged with the driving column, the sliding block is pushed vertically upward with the displacement of the driving rod, and the two connecting plates are driven to move vertically upward, thereby driving the two fourth transmission rods to move, thereby pulling the two push rods to move away from each other in the horizontal direction, and then driving the two connecting blocks to move away from each other in the horizontal direction. At this time, the two glass doors are pulled to move away from each other, so that the display cabinet can be opened, achieving the effect of automatic opening of the door.

[0041] The above embodiment discloses an automatic opening and closing device for a display cabinet with a protective structure, wherein the cylinder body 5 is pulled by opening the cabinet door 2, and the connecting rod 11 is driven to move at the same time. At this time, the sliding rod 10 slides inside the sliding bracket 9 to assist in movement. When the connecting rod 11 rotates, the transmission rod 7 is driven to rotate, and the transmission rod 7 drives the first gear 13 to rotate. Since the first gear 13 is engaged with the inner wall of the piston 12, the piston 12 moves laterally and squeezes the reset spring 14 at the same time. When the operator lets go, the reset spring 14 drives the piston 12 to reset and drives the first gear 13 to reset at the same time. The cabinet door 2 is automatically closed by the movement of the connecting rod 11 and the sliding rod 10. The device can automatically open and close the cabinet door 2 of the display cabinet to prevent the operator from forgetting to open the cabinet door 2. When the cabinet door 2 is closed, the limit block 20 is pushed inward, and at this time, the limit block 20 drives the rack 17 to be pushed inward, and at the same time, the rack 17 drives the first gear 13 to rotate, and at the same time pulls the clockwork spring 15. When the cabinet door 2 is opened, the clockwork spring 15 is reset, and the rack 17 is driven to move by the rotation of the first gear 13, so that the limit block 20 rebounds outward, so that when the cabinet door 2 is closed again, the limit block 20 is limited again. The device protects the safety of the operator by limiting the cabinet door 2, reduces the occurrence of accidents, and increases the practicality of the device.

[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
