[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0017] like Figure 1-4The illustrated administrator function combination U-lock includes a lock housing 1. The lock housing 1 contains a lock hole 11, a lock plate 12 that extends and retracts relative to the lock hole 11, a combination wheel 3, a push plate 13 that controls the movement of the lock plate 12 by unlocking via the combination wheel 3, and a key lock cylinder 2. The key lock cylinder 2 includes a lock cylinder 21 with a cam 22, an unlocking plate 23 that extends relative to the combination wheel 3 driven by the lock cylinder 21, and a pusher 24 that accommodates the unlocking plate 23.

[0018] As a further provision of the above solution, the pusher 24 includes a horizontal movable plate 241, a return spring 242, and a vertical movable plate 243. The horizontal movable plate 241 is provided with an inclined drive groove 244, and the back of the vertical movable plate 243 is provided with a slider 245 that moves within the inclined drive groove 244. One end of the horizontal movable plate 241 abuts against the cam portion 22 of the lock cylinder 21, and the other end abuts against the return spring 242.

[0019] As a further feature of the above scheme, each set of password disks on the password wheel 3 is provided with a locking ring 32 with a notch 31 on one side, and the size of the notch 31 of the locking ring 32 matches the unlocking plate 23.

[0020] As a further feature of the above solution, the push plate 13 is exposed on the surface of the lock housing 1, and one end of it extends into the lock housing 1 and is connected to the lock plate 12. The lock housing 1 is also provided with a rotating plate 18 with a rotating shaft 19. The rotating plate 18 is also provided with a rotating rod 17. The lock plate 12 is provided with a linkage hook groove 16 that matches the rotating rod 17. The lock plate 12 in the lock holes 11 on both sides is locked or unlocked synchronously through the linkage of the rotating plate 18.

[0021] As a further provision of the above scheme, the combination wheel 3 is also provided with a combination setting component 7. The combination setting component 7 includes a control rod 71 extending out of the lock case 1. The control rod 71 is provided with a cam structure 72. The cam structure 72 is used to drive the inner shaft 38 of the combination wheel 3 to move, so that the inner shaft 38 drives the lock ring 32 to disengage from the combination disc of the combination wheel 3.

[0022] Example 1

[0023] The working principle of the lock body of this utility model includes the following: When using the lock body of this embodiment, the key lock cylinder 2 is rotated by the corresponding key. When the key corresponds to the key lock cylinder 2, the lock cylinder 21 rotates, and the cam portion 22 on the lock cylinder 21 rotates. Based on the switching of the cam portion 22, the transverse movable plate 241 abutting against the cam portion 22 moves towards the return spring 242. Based on the inclined drive groove 244 provided on the transverse movable plate 241, and because the transverse movable plate 241 is restricted to transverse movement by the lock shell 1, the inclined drive groove 244 drives the vertical movable plate 243, which has a movable slider 245 located inside it and can only move vertically, to produce a vertical movement. Figure 2 As shown, a receiving groove 25 is also provided on the vertical movable plate 243. An unlocking plate 23 and a spring member 26 are also provided in the receiving groove 25. When the vertical movable plate 243 does not move upward, there is still a gap between the unlocking plate 23, which is pushed to the end of the receiving groove 25 by the spring member 26, and the locking ring 32. However, when the vertical movable plate 243 is in the upward position, the unlocking plate 23 also moves upward. At this time, depending on whether the notch 31 on the locking ring 32 is opposite to the unlocking plate 23, two states will occur: the unlocking plate 23 is inserted into the notch 31 of the locking ring 32 or it is not inserted. If it is not inserted, the unlocking plate 23 will move in the opposite direction, compressing the spring member 26. The spring member 26 stores force to push the unlocking plate 23 to move continuously toward the locking ring 32 until the administrator rotates the combination dial to rotate the locking ring 32 until the notch 31 is opposite to the unlocking plate 23.

[0024] It is worth noting that in the above structural principle, the state of the unlocking plate 23 inserting into the notch 31, i.e. the state of the key dial displaying the correct password numbers, is controlled by the lock cylinder 21 of the key lock cylinder 2 to unlock it as described above. Then, by continuously turning all the key dials until all the unlocking plates 23 are inserted into the notch 31, the accurate and true password of the current lock can be obtained, and it can be unlocked by pushing the plate 13. Under this design premise, the user only needs to modify the key matching cylinder in the lock cylinder 21 to use one key to match multiple lock bodies. Furthermore, assuming that the user has multiple locks used in different stores or factories, it is convenient for different employees to set different passwords for multiple locks individually, so that the basic unlocking password is controlled by different employees, but the manager can still use the same key to obtain and retrieve the lock password in the administrator mode, which facilitates flexible control of the lock.

[0025] Example 2

[0026] Furthermore, as in the lock body structure of the above embodiment, the locking of the U-shaped lock beam in this embodiment adopts a locking plate 12 extending from the push plate 13. In this embodiment, the lock shell 1 is also provided with a rotating plate 18 with a rotating shaft 19. The rotating plate 18 is also provided with a rotating rod 17. The locking plate 12 is provided with a linkage hook groove 16 that matches the rotating rod 17. The locking plate 12 in the lock holes 11 on both sides is locked or unlocked synchronously through the linkage of the rotating plate 18. With this structure, the locking plate 12 in the two lock holes 11 can be smoothly controlled to lock and unlock quickly and synchronously, which is convenient for the use of the lock.

[0027] Example 3

[0028] Furthermore, in this embodiment, the lock body also provides a simple password modification setting structure. This structure is basically based on the existing technology. Its feature is that it allows users to modify the password on the basis of the above. By using the control lever 71 to drive the inner shaft 38 to push the lock ring 32 to disengage from the password disk when the password is correctly unlocked, the password disk can be rotated at will until the lock ring 32 is reset, that is, the new password is reset. Its core point is that when the corresponding value of the password disk is modified, the lock ring 32 still maintains the value at the farthest end of the notch 31 as the unlock password number.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
