[0012] Optionally, both ends of the limiting plate are connected to an inclined guide plate.

[0013] By adopting the above technical solution, the guide plate can make the limit plate contact with the first travel switch or the second travel switch smoothly to avoid exceeding the travel.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. When the goods fall on the conveyor belt, the protective cover moves up, and the protective plate under the protective cover can immediately close the feeding port. When the conveyor belt conveys the goods to the feeding port, the protective cover and the protective plate move down synchronously until the protective cover is in close contact with the conveyor belt, thereby preventing criminals from stealing the goods in the vending machine through the feeding port, thereby enhancing the anti-theft performance of the vending machine. The structure is simple, the later maintenance is relatively simple, and it saves time and effort.

The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0026] The embodiment of the present application discloses a door mechanism with anti-theft function. Figure 1 and Figure 2, including a door panel 1, an inner wall of the door panel 1 is provided with an installation cavity 11, an outer wall of the door panel 1 is provided with a material taking port 12 connected with the installation cavity 11, and a conveyor belt 13 for conveying goods is installed on the inner wall of the installation cavity 11.

[0027] Reference Figure 1 and Figure 3 A cuboid protective cover 2 is slidably connected to the inner side wall of the installation cavity 11 in the vertical direction, and the lower end face of the protective cover 2 and the side facing the material taking port 12 are both provided with openings. The lower end face of the protective cover 2 is in close contact with the surface of the conveyor belt 13, and a protective plate 3 for closing the material taking port 12 is fixedly connected to the lower end face of the protective cover 2. A driving component 4 for driving the protective cover 2 to slide up and down is installed on the bottom wall of the lower end of the installation cavity 11. When the goods fall on the conveyor belt 13, the protective cover 2 moves up, and the protective plate 3 under the protective cover 2 can close the material taking port 12 immediately. When the conveyor belt 13 conveys the goods to the material taking port 12, the protective cover 2 and the protective plate 3 move down synchronously until the protective cover 2 is in close contact with the conveyor belt 13, thereby preventing criminals from stealing the goods in the vending machine through the material taking port 12, thereby enhancing the anti-theft performance of the vending machine.

[0028] Reference Figure 3 , Figure 4 and Figure 5 Two sliding guide rails 5 are fixedly connected in parallel along the vertical direction on the inner side wall of the installation cavity 11, and mounting plates 6 are fixedly connected to the opposite sides of the protective cover 2 and the protective plate 3. Both ends of each mounting plate 6 are rotatably connected to sliding rollers 61 that are slidably matched with the sliding guide rails 5. The protective cover 2 and the protective plate 3 can slide upward along the length direction of the sliding guide rails 5 through the sliding rollers 61.

[0029] Reference Figure 3 and Figure 4 The driving assembly 4 includes a reduction motor 41, a driving gear 43 and a driven gear 44. The reduction motor 41 can rotate in the forward or reverse direction. A fixing seat 45 is fixedly connected to the bottom wall of the lower end of the installation cavity 11. The reduction motor 41 is fixedly installed on one side of the fixing seat 45. The output shaft of the reduction motor 41 passes through the fixing seat 45 and is fixedly connected to the driving gear 43. The lower end of the protective cover 2 is fixedly connected to the support rod 21 in the horizontal direction. The driven gear 44 is rotatably connected to the support rod 21. A transmission belt 46 is commonly sleeved between the driving gear 43 and the driven gear 44. The lower end of the protective plate 3 is connected to the fixed block 31, and the transmission belt 46 is fixedly connected to the fixed block 31. The reduction motor 41 drives the driving gear 43 to rotate, and the driving gear 43 and the driven gear 44 jointly drive the transmission belt 46 to rotate, and the transmission belt 46 drives the protective plate 3 and the protective cover 2 to move upward.

[0030] Reference Figure 3 , Figure 4 and Figure 5 , a positioning bar 7 is connected to the inner side wall of the installation cavity 11 in the vertical direction, and the first travel switch 71 and the second travel switch 72 for controlling the reduction motor 41 are fixedly connected to the positioning bar 7 in sequence from top to bottom in the vertical direction, and a limit plate 62 for contacting the first travel switch 71 and the second travel switch 72 is vertically connected to one side of the installation plate 6, and both ends of the limit plate 62 are connected to an inclined guide plate 63. When the protective cover 2 rises, when the limit plate 62 contacts the first travel switch 71, the first travel switch 71 controls the reduction motor 41 to reverse, and the protective cover 2 starts to descend; after the protective cover 2 descends, when the limit plate 62 contacts the second travel switch 72, the second travel switch 72 controls the reduction motor 41 to stop working, and at this time, the lower end of the protective cover 2 is in close contact with the conveyor belt 13.

[0031] The implementation principle of the warehouse door mechanism with anti-theft function in the embodiment of the present application is: when the goods fall on the conveyor belt 13, the protective cover 2 moves up, and the protective plate 3 under the protective cover 2 can immediately close the material taking port 12; when the conveyor belt 13 conveys the goods to the material taking port 12, the protective cover 2 and the protective plate 3 move down synchronously until the protective cover 2 is in close contact with the conveyor belt 13, thereby preventing criminals from stealing the goods in the vending machine through the material taking port 12, thereby enhancing the anti-theft performance of the vending machine, and having a simple structure and relatively simple later maintenance, saving time and effort.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
