[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0046] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] For ease of explanation, this embodiment exemplifies the structure of the door leaf used as a room door, but the anti-theft display cabinet of this patent is not limited to use as a house door, and can also be used in cabinets, boxes and other occasions with openable and closable door leaves.

[0048] A theft-proof display cabinet Figures 1 to 4 As shown, it comprises: a cabinet 1, one side of which has an opening 11;

[0049] A lifting platform 2 is arranged in the cabinet, and the tabletop of the lifting platform can be raised or retracted from the opening;

[0050] The cabinet door 3 comprises a chain-type structure door consisting of a plurality of flat plates 31 connected end to end;

[0051] In this embodiment, Figure 4 As shown, a matching slot structure 311 is provided between adjacent plates, and the rotation connection between two adjacent plates is achieved through the slot structure.

[0052] Track 4, such as Figure 5 As shown, the cabinet door is arranged at the opening, and is connected to the track and can slide along the track, and the sliding cabinet door can cover the opening.

[0053] In a specific usage scenario, when it is used for normal display, the lifting platform is raised and the items to be displayed are placed on the lifting platform for display; when display is not needed, or when danger is detected, the lifting platform descends and retracts into the cabinet from the opening, and then the cabinet door moves to the opening to cover the opening. At this time, the cabinet is a closed structure (of course, the closure here is not an airtight seal, it just closes the cabinet), which is automatically closed to prevent people from taking away the exhibits.

[0054] In this embodiment, the track is provided with two groups, and the two groups of the track are symmetrically arranged on opposite sides of the cabinet. The cabinet door is mounted on the two tracks. It is well understood that the tracks on both sides can provide the cabinet door with smoother movement and more reliable after closing.

[0055] like Figure 6 As shown, the track has a C-shaped track groove 41, and there are two ways to connect the cabinet door and the track. The tracks of the two structures are the same, namely:

[0056] 1. Both ends of the cabinet door are slidably connected to the track groove (not shown);

[0057] 2. Rollers are provided at both ends of the cabinet door, and the rollers are arranged in the track groove ( Figure 6 ).

[0058] It is easy to understand that the two structures are rolling connection and sliding connection. Both structures have their own advantages and disadvantages. The rolling connection has smoother opening and closing, but the roller is expensive and easy to damage; the sliding connection is simple and not easy to break.

[0059] Regarding the driving method of the cabinet door, the simplest method is to use cable traction, that is, to set traction ropes (not shown in the figure) at both ends of the cabinet door's movement direction, and then use power elements such as motors or cylinders to drag at both ends respectively to achieve covering and removal of the cabinet door.

[0060] The present application also provides another more stable traction method, such as Figure 7 As shown, a chain 5 is arranged in the track, the chain is arranged on the track, and the cabinet door is fixedly connected to the chain and driven by the chain.

[0061] That is, the traction action is completed by the chain, and the chain embedded in the guide rail has a more stable movement path and power, and will not be exposed to the outside like a traction rope, reducing the risk of failure.

[0062] The cabinet door is designed to open and close better. Figure 8As shown, the guide rail includes two sections to accommodate the positions of the cabinet door in two states respectively. In this embodiment, the rail includes a horizontal groove 42 and a vertical groove 43. When the cabinet door is located in the horizontal groove, the opening is covered; when the cabinet door is located in the vertical groove, the opening is open.

[0063] Meanwhile, if the shape of the cabinet body affects the length of the cabinet door and the vertical groove is not enough, a second horizontal groove 44 is provided at the bottom, that is, when the cabinet door is opened, the cabinet door is located in the vertical groove box and the second horizontal groove.

[0064] In this embodiment, the track is set to a U-shaped structure. In this case, the chains at both ends can be made into two independent ones or closed into a whole one. However, if the cabinet is really short in the vertical direction, that is, the vertical groove is less than half of the horizontal groove, the U-shaped track will not have enough space for the chain to move.

[0065] At this time, it can be set to a back-shaped structure, such as Fig. 9 As shown, there are two second transverse grooves 44 in the U-shaped track, so the chain is also designed in two sections and is independent of each other.

[0066] For the traction power of the cabinet door, the traction mechanism 6 in this embodiment is as follows: Figure 5 As shown, it includes a first motor 61, and the output end of the motor is connected to the cabinet door to drive the cabinet door to slide along the track.

[0067] Specifically, it also includes a traction shaft 62, and traction gears 63 are set at both ends of the traction shaft. The two groups of chains are connected to the traction gears. At the same time, there are two traction shafts, which are respectively connected to the two ends (movement direction) of the cabinet door to realize the movement of the cabinet door in two directions.

[0068] The output shaft of the first motor is driven by a belt to one of the traction shafts, and a synchronous belt is also arranged between the two traction shafts to realize synchronous rotation of the two traction shafts.

[0069] In addition, the lifting platform in this embodiment is also provided with a driving mechanism and a guiding mechanism; Fig.10 As shown, the driving mechanism includes a second motor 21, which drives the lifting platform to move through a gear 22 and a rack 23; the guiding mechanism includes a guide column 24 fixedly connected to the bottom of the lifting platform and a guide sleeve 25 fixedly connected to the counter.

[0070] In addition, the display cabinet in this embodiment further comprises a transparent cabinet 7 , which is connected to the cabinet body and disposed at one side of the opening; at least one side of the transparent cabinet exposed to the outside is a transparent panel 71 .

[0071] In this embodiment, all display sides of the transparent cabinet are transparent so that exhibits can be seen from multiple angles.

[0072] In addition, the transparent panel is glass, and valuables can also be set as bulletproof glass. Moreover, the transparent panel is also provided with a glass break detector, and the glass break detector is electrically connected to the controller, and the controller is also electrically connected to the lifting platform and the cabinet door.

[0073] When the glass is damaged, the control system immediately controls the display lift to descend and retract, and closes the cabinet door to prevent the exhibits from being stolen.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
