In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0030] First embodiment: See Figures 1-8 A disassembly and assembly for a vending machine lock, comprising a door body 1, the disassembly and assembly further comprising: Lock bracket 2, which is detachably mounted on door body 1 by fasteners and located on the side of door body 1; The disassembly / assembly position 101 is located on the side of the door body 1 and is correspondingly arranged with respect to the lock bracket 2. The disassembly / assembly position 101 is used for disassembling and installing the lock bracket 2 and the door body 1.
[0031] By detachably installing the lock bracket 2 on the inner side of the door body 1 and providing a disassembly / reassembly position 101 at the corresponding location on the door body 1, the door body 1 and the lock bracket 2 can be easily disassembled and separated. Compared with the traditional top locking mechanism (door lock mechanism), this structure allows maintenance personnel to directly disassemble and separate the door body 1 and the lock bracket 2 through the disassembly / reassembly position 101 on the side when the locking mechanism (door lock mechanism) fails, greatly improving maintenance convenience.
[0032] The door body 1 is provided with door body accessories, which are used to detachably connect with the lock bracket 2. The lock bracket 2 is detachably installed on the door body 1 through the door body accessories.
[0033] By setting door body accessories, the lock bracket 2 can be detached and fixedly installed on the door body 1. When the door lock mechanism is working normally, the door lock mechanism and the lock bracket 2 cooperate to lock the door body 1. When the door lock mechanism fails, the door body accessories and the lock bracket 2 can be disassembled and separated. Even when the door lock mechanism and the lock bracket 2 are locked, the door body 1 can still be opened.
[0034] The door fitting is a door liner 102, which is installed on the side of the inside of the door body 1.
[0035] The door liner 102 provides a stable mounting base for the lock bracket 2, ensuring the reliability of the connection between the door body 1 and the lock bracket 2, while also facilitating quick disassembly during maintenance. The door liner 102 is installed on the side of the inside of the door body 1, and the fixed connection between the door liner 102 and the lock bracket 2 can be concealed in the space inside the door body 1.
[0036] The inner side of the door body 1 is provided with a groove 103 for installing the handle assembly 3 and forming a disassembly position 101.

This layout avoids the space limitations of traditional top locking, making the opening of the door body 1 more flexible. At the same time, the combination of the side locking mechanism and the detachable design of the door body 1 ensures that the door body 1 can still be quickly opened through the disassembly position 101 even if the locking mechanism fails, which significantly improves the reliability and maintenance convenience of the equipment.
[0049] The lock bracket 2 is correspondingly set to the door lock mechanism and is located on the left or right side of the inner side between the body 4 and the door body 1.
[0050] The door lock mechanism includes a door lock driver and a lock rod 5 that is axially telescopically movable on the door lock mechanism. The door lock driver is connected to the lock rod 5 in a transmission connection. The lock bracket 2 is provided with a lock hole 202 that cooperates with the lock rod 5. When the door body 1 is closed on the machine body 4, the lock rod 5 extends out and inserts into the lock hole 202 to lock the door body 1 on the machine body 4. When the door body 1 and the lock bracket 2 are disassembled and separated at the disassembly position 101, the door body 1 can be opened on the machine body 4 with the lock rod 5 inserted into the lock hole 202.
[0051] The door lock mechanism is an existing electronic lock. The door lock driver and the lock rod 5 can be connected by a mechanical transmission structure such as gears, which will not be described in detail here.
