[0029] As a preferred embodiment, an outer sleeve 14 is sleeved outside the steel wire rope 7, and the material of the outer sleeve 14 is rubber. One end of the outer sleeve 14 close to the circular limiting ball 11 is fixedly connected with an adjusting sleeve 15, and an external thread 16 is arranged at one end of the adjusting sleeve 15. By providing the adjusting sleeve 15, the purpose is to adjust the distance between the outer sleeve 14 and the connecting plate 4, so that the steel wire rope 7 can be telescoped (inside the outer sleeve 14), and then the position of the steel wire rope 7 on the connection groove 6 can be adjusted.
[0030] As a preferred embodiment, a notch is also arranged on the mounting plate 5. The adjusting sleeve 15 extends into the notch and is threadedly connected with a first nut 17 and a second nut 18, and the first nut 17 and the second nut 18 respectively abut against the inner side and the outer side of the housing 1. Installing the adjusting sleeve 15 on the notch can save the installation space, and the external thread 16 on the adjusting sleeve 15 can just be threadedly connected with the first nut 17 and the second nut 18. After adjusting the position, the adjusting sleeve 15 can be fixedly connected to the housing 1 to form a better adjusting and installing structure.
[0031] As a preferred embodiment, a first bending edge 19 and a second bending edge 20 are respectively arranged on the housing 1, and screw holes are arranged on both the first bending edge 19 and the second bending edge 20, and screws 21 are installed in the screw holes. It can be understood that by providing the first bending edge 19 and the second bending edge 20, it is convenient to install the housing 1 on the door edge of the cabinet, and the two places are fastened, and the fixing effect is better.
[0032] As a preferred embodiment, adjustment holes 22 are provided at the upper and lower ends on the side of the housing 1 close to the T-shaped lock 3, and the T-shaped lock 3 is installed on the housing 1 through a screw and a nut. It can be understood that the adjustment holes 22 are elliptical structures, and the screw can be adjusted up and down inside the adjustment holes 22, so as to adjust the position of the T-shaped lock 3 on the housing 1. After the T-shaped lock 3 is connected to the screw, the screw is inserted into the adjustment holes 22, and finally fastened with a nut (the outer shell of the T-shaped lock 3 is fixed. The T-shaped lock 3 is also provided with a rotating handle and a rotating mechanism, both of which are installed on the outer shell, and the rotating mechanism corresponds to the moving end in this article).
[0033] In this application, the T-shaped lock 3 is a T-shaped lock 3 of model MK210 produced by Xiamen Meike Security Technology Co., Ltd. The T-shaped lock 3 includes a lock body and a lock core. The lock core is installed inside the lock body, and the locking piece on the lock core is clamped in the limit hole of the lock body. When the lock core is rotated to open with a key, the locking piece on the lock core will leave the limit hole of the lock body. At this time, the lock body can be rotated, and when the lock body rotates, it can drive its moving end to rotate, and finally drive the connecting plate 4 to rotate. Therefore, in this T-shaped lock 3, the function of the lock core is to lock the lock body so that the lock body cannot rotate when the limit is not released; in addition, the lock core can also be replaced according to the user's situation, that is, the original lock core is disassembled before sale and a limit pin is installed. The limit pin can block the limit hole of the lock body. After the user gets this unlocking device, the limit pin can be taken out and a new lock core can be installed. The advantage of this is that the safety protection level can be greatly improved (replace the user's own lock core).
[0034] The working principle of the present utility model is as follows: When using this device, first connect the extending end of the steel wire rope 7 to the mechanical end of the electronic lock. When the steel wire rope 7 is pulled down, the mechanical end on the electronic lock can be pulled, so as to rotate and open the locking end of the electronic lock, so that the locking end of the electronic lock is separated from the lock post of the cabinet door, and then the cabinet door can be opened; and the electronic lock is an electronic lock of model J-R4-EM-87 produced by Southco Asia Limited. The electronic lock has a mechanical end and a locking end, and can form a supporting set with this device.
[0035] During work, first insert the key and rotate the T-shaped lock 3. The T-shaped lock 3 will drive the connecting plate 4 to rotate, and then drive the steel wire rope 7 to pull to the left. The steel wire rope 7 in the vertical direction is in a downward pulling state, and the spring 8 generates elastic force when rotating. When the external force is lost (at the T-shaped lock 3), the T-shaped lock 3 can be rotated back to its original position through the spring 8, making it more convenient to use in the process and having a better use effect.
[0036] It should be noted that the main problems in the prior art are as follows: when there is a power outage or the electronic lock fails in the existing vending cabinets, the electronic functions cannot be used, resulting in a reduced usage effect of the electronic lock (or it is extremely inconvenient as professional maintenance personnel are required to open the cabinet door).
[0037] Therefore, after the improvement of this application, by providing a mechanical unlocking mechanism 2 and a T-shaped lock 3, the cabinet door can be opened with this mechanical lock during a power outage or when the electronic lock fails. Moreover, the method of opening the cabinet door with this mechanical lock is relatively simple, its structure is compact, it can be reset in time under the action of the spring 8, and the external force output is small. As a backup unlocking method, it can greatly improve the usage effect of the vending cabinet.
