The first connecting shaft 7 and the second connecting shaft 8 are movably connected through the rotating shaft 10 to control the opening of the cabinet door 2.

[0038] In this embodiment, when the cabinet door 2 is in the open position, the first connecting shaft 7 extends outward, and the second connecting shaft 8 rotates around the first connecting shaft 7 through the rotating shaft 10. When a 90° angle is formed between the first connecting shaft 7 and the second connecting shaft 8, the cabinet door 2 will no longer rotate because the second connecting shaft 8 has been pulled to the limit value. The staff does not need to worry about their hands being pinched when replenishing goods.

[0039] In order to ensure the stability of the structure of this embodiment, the first mounting and positioning portion 6 is a rectangular plate, and a movable joint is provided in the middle of the first mounting and positioning portion 6 for connecting the second connecting shaft 8; threaded holes are arranged in the first mounting and positioning portion 6 for connecting to the bottom plate of the vending machine 1.

[0043] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0044] Since a movable connection is formed between the first connecting shaft 7 and the second connecting shaft 8 of the cabinet door positioning mechanism 3 through the rotating shaft 10, when the first connecting shaft 7 extends, the second connecting shaft 8 rotates around the first connecting shaft 7, and the second connecting shaft 8 can pull the cabinet door 2 to open and position it, avoiding the situation where the cabinet door is pushed by external force and causes injuries or pinching of people.

[0045] Since a double-ear seat 82 is provided at one end of the second connecting shaft 8, and bolt holes 83 are arranged on both sides of the double-ear seat 82, the second connecting shaft 8 can be connected and fixed to the inner wall of the cabinet door 2 through the bolt holes 83, forming a first point connection and fixation of the second connecting shaft 8;

[0046] Since the second connecting shaft 8 is provided with a single ear 81 at the other end, the second mounting positioning portion 9 is connected to the cabinet door mounting frame 5 of the cabinet door 2 through the through hole 92; therefore, the single ear 81 and the second mounting positioning portion 9 are connected by the pin 91, forming a second point connection and fixation of the second connecting shaft 8;

[0047] Since the second connecting shaft 8 is fixed to the bottom of the cabinet door 2 by a two-point connection method, the second connecting shaft 8 has a high connection strength, thereby driving the cabinet door 2 to rotate.

[0048] Since the cabinet door positioning mechanism 3 is arranged in the space surrounded by the bottom plate of the vending machine 1, the side plate of the vending machine 1 and the hopper 4, when the cabinet door positioning mechanism 3 is opened, the opening angle of the cabinet door 2 can be determined according to the telescopic length of the first connecting shaft 7 of the cabinet door positioning mechanism 3 and the position of the hopper 4, and can be limited by the position of the hopper 4. When the cabinet door positioning mechanism 3 rests on the hopper 4, the cabinet door 2 will no longer be opened.
