[0001] This utility model relates to the technical field of display case opening and closing structures, and in particular to a display case opening structure. Background Technology

[0002] With the increasing popularity of electric display cases in exhibition halls, museums and other venues, their application is becoming more and more common. Most existing electric display cases use two methods to open the movable glass panels: horizontal sliding and flipping. Both require movement into the external space. Among them, sliding requires the largest displacement space, and both methods partially obstruct the view after opening, affecting the placement and retrieval of items by staff. Moreover, the glass panels are prone to deformation and damage when open for extended periods. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a display case opening structure that addresses the above-mentioned technical deficiencies. By driving the glass panel to slide down into the display case, the opening process does not require external space, and the entire glass panel is located inside the display case without external obstruction, making it convenient to place and retrieve items.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a display cabinet opening structure, including a display cabinet and a glass plate slidably connected to the top of the display cabinet, and further including: a through groove connected to the space below is provided on the top of the display cabinet, positioning channels are symmetrically provided on both sides of the through groove inside the display cabinet, a lifting component is provided between the two positioning channels, and sliding parts connected to the positioning channels are symmetrically provided on both sides of the bottom of the glass plate, and the middle part is connected to the lifting component.

[0005] Preferably, rollers are arranged at equal intervals on the inner side of the positioning channel, and guide grooves are symmetrically provided at the front and rear of the positioning channel. The side of the sliding member contacts the rollers, and guide sliders connected to the guide grooves are symmetrically provided at the front and rear.

[0006] Preferably, the lifting assembly includes a bracket, a threaded rod, and a support; the brackets are arranged in pairs and are respectively located above and below the positioning channel, with support rods symmetrically arranged between the two brackets, the threaded rod being located between the two support rods, and one end of the threaded rod being provided with a motor fixedly connected to the bracket; the two ends of the support are slidably connected to the support rods, the middle part is threadedly connected to the threaded rod, and the front of the support is connected to the bottom of the glass plate.

[0007] Preferably, the bracket has two symmetrically arranged extension plates at the front, and the ends of the extension plates are provided with fixing holes.

[0008] Preferably, the sliding member is provided with multiple filling grooves.

[0009] Preferably, the sliding component has an oil reservoir at its center, and multiple ropes are arranged inside the oil reservoir, with one end of each rope passing through the filling groove.

[0010] Preferably, the bottom of the positioning channel is provided with a slot, and a collection box is provided in the slot.

[0011] Preferably, the bottom surface of the filling groove is inclined from the inside out.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The glass panel slides down into the display case through the slot. It does not occupy external space during the opening process, so there is no need to consider the layout of the display case.
