Description

Technical Field

[0001] The utility model relates to a cabinet door hinge in the field of automatic vending machines, in particular to an opening and closing structure of a door of an automatic vending machine. Background Art

[0002] Vending machines are now widely used and are commonly found in busy locations such as large shopping malls, train stations, subway stations and airplane waiting rooms.

[0003] In the past, the doors of vending machines were all made of glass and frame. When people were purchasing, they could see the status of the goods inside through the glass of the door. However, the functions of such vending machines were relatively simple and they did not serve the purpose of display.

[0004] Currently, the new vending machines use steel doors as cabinet doors, and a whole display screen is set on the steel door. While waiting for customers to use it, the display screen can play the introduction of the product, or be used to put in other advertisements or movie introductions, etc., which can increase the seller's revenue.

[0005] Especially in some large venues, a whole row of vending machines can be set up against the wall, which can enhance people's experience when the video is playing.

[0006] However, in the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0007] Since vending machines are arranged in a row, and to minimize screen interruptions, the frames of the vending machines are designed to be thin enough. Since the hinge is located between the cabinet door and the cabinet body, the cabinet door needs a rotation gap when opening, and the cabinet door occupies the side space of the cabinet body. Therefore, when it is necessary to restock or repair the vending machine, the doors of the vending machines can only be opened one by one from right to left or from left to right according to the order in which the vending machines are arranged. Otherwise, the door of the vending machine to be restocked or repaired will not be opened because the door of the vending machine next to it is not opened. Summary of the Invention

[0008] To address the shortcomings of the prior art, the present invention provides a door opening and closing structure for vending machines, which is designed to have sufficiently thin door frames and are placed side by side in close proximity, so that opening a single vending machine is not affected by the adjacent vending machines. This door opening and closing structure utilizes the collinear outward movement of the top and bottom rotating shafts, away from the front of the cabinet and closer to the outer surface of the cabinet door. This structure eliminates the need to occupy side space when the cabinet door rotates, thus resolving the technical issue of opening the doors of vending machines placed side by side in close proximity.

[0009] The solution adopted by the embodiment of this application to solve the technical problem is:

[0010] A vending machine door opening and closing structure includes an opening and closing structure, wherein the opening and closing structure includes a protruding connecting block, a top rotating shaft, a bottom rotating shaft and a supporting platform;

[0011] The protruding connecting block is an L-shaped structure, one side of which is connected to the cabinet body and is fixed to one end of the top front of the cabinet body in a cantilever manner, and the other side is provided with a through hole for connecting the cabinet door; the top rotating shaft passes through the through hole on the protruding connecting block and is assembled at one end of the top of the cabinet door, so that the cabinet door can rotate with the top rotating shaft as the axis; the bottom rotating shaft is a stepped shaft, the upper part of the bottom rotating shaft is connected to one end of the bottom of the cabinet door, and is collinear with the top rotating shaft, so that the cabinet door rotates around the collinearity of the top rotating shaft and the bottom rotating shaft as the axis; a shoulder is provided in the middle to form a press-fit limit block for supporting the cabinet door; a support is arranged on the front of the bottom of the cabinet body 1, and the lower part of the bottom rotating shaft is assembled on the support, and its shoulder is located on the plane of the support to play a limiting role;

[0012] Among them, the collinearity of the top rotating shaft and the bottom rotating shaft is close to the outer surface side of the cabinet door. By moving the top rotating shaft and the bottom rotating shaft away from the front of the cabinet body, the collinearity of the top rotating shaft and the bottom rotating shaft is moved outward. When the cabinet door rotates with the collinearity of the top rotating shaft and the bottom rotating shaft as the rotation center, it can avoid the interference caused by the cabinet door flipping outward and occupying the side space of the cabinet body when it is opened.

[0013] In order to further solve the technical problems to be solved by the embodiments of the present application, in the cabinet door provided by the embodiments of the present application, a display screen is provided on the upper part of the cabinet door, and the display screen is assembled on the cabinet door through a frame; a horizontal positioning plate and a vertical positioning plate are provided on the cabinet door to form a frame structure, and arc grooves are provided at the left and right ends of the horizontal positioning plate for assembling the top rotating shaft and the bottom rotating shaft respectively, and rectangular grooves are provided at the upper and lower ends of the longitudinal positioning plate for accommodating the top rotating shaft and the bottom rotating shaft respectively, and the rectangular grooves and the arc grooves correspond to and converge to assemble the top rotating shaft and the bottom rotating shaft for axial and radial positioning.

[0014] Furthermore, the arc slot is half a slot, which facilitates the fastening of the top rotating shaft and the bottom rotating shaft.

[0015] Furthermore, the horizontal positioning plate has multiple arc slots and the longitudinal positioning plate has multiple rectangular slots for adjusting the setting positions of the top rotating shaft and the bottom rotating shaft of the cabinet door.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Although the embodiments of the present invention have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present invention.

[0056] The embodiment of the present application solves the problem of interference between doors when opening vending machines side by side in the prior art by providing a door opening and closing structure for vending machines. In the opening and closing structure, the rotating shaft is located near the outer side of the door to ensure that the door does not occupy the side space of the cabinet when it is rotated and opened, does not interfere with adjacent vending machines, and can independently open any vending machine.

[0057] As shown in the figure, a vending machine door opening and closing structure includes an opening and closing structure 6, which includes a protruding connecting block 61, a top rotating shaft 62, a bottom rotating shaft 63 and a support platform 64;

[0058] The protruding connecting block 61 is an L-shaped structure, one side of which is connected to the cabinet body 1 and fixed to one end of the top front of the cabinet body 1 in a cantilever manner, and the other side is provided with a through hole for connecting to the cabinet door 2;

[0059] The top rotating shaft 62 is a circular shaft that passes through the through hole on the protruding connecting block 61 and is assembled on one end of the top of the cabinet door 2, so that the cabinet door 2 can rotate around the top rotating shaft 62 as the axis;

[0060] The bottom rotating shaft 63 is a stepped shaft. The upper portion of the bottom rotating shaft 63 is connected to one end of the bottom of the cabinet door 2 and is collinear with the top rotating shaft 62. The cabinet door 2 then rotates around the collinear axis of the top rotating shaft 62 and the bottom rotating shaft 63, thereby opening the cabinet door 2. A shoulder is provided in the middle to form a press-fit limit block for supporting the cabinet door 2.

[0061] The support platform 64 is a strip-shaped structure, which is arranged on the front of the bottom of the cabinet 1. The lower part of the bottom rotating shaft 63 is assembled on the support platform 64, and its shaft shoulder is located on the plane of the support platform 64 to play a role in limiting.

[0062] Among them, the collinearity of the top rotating shaft 62 and the bottom rotating shaft 63 is close to one side of the outer surface of the cabinet door 2. By moving the top rotating shaft 62 and the bottom rotating shaft 63 away from the front of the cabinet body 1, the collinearity of the top rotating shaft 62 and the bottom rotating shaft 63 is moved outward. When the cabinet door rotates with the collinearity of the top rotating shaft 62 and the bottom rotating shaft 63 as the rotation center, the interference caused by the cabinet door 2 flipping outward and occupying the side space of the cabinet body 1 when it is opened can be avoided. Therefore, when the adjacent vending machine cabinet doors 2 are opened, they do not interfere with each other and can be opened independently.

[0063] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:
