[0024] like Figure 1-4As shown, the utility model provides a technical solution: comprising a lock body assembly 1, the bottom of the lock body assembly 1 is sequentially sleeved with a lock core assembly 2 and a docking assembly 3 from top to bottom, and a key assembly 4 is magnetically adsorbed on the middle of the front of the docking assembly 3;

[0025] The lock body assembly 1 comprises a U-shaped lock beam 101, a lock rod 102 is provided at both ends of the U-shaped lock beam 101, a connecting round rod 103 is fixedly installed at both ends of the U-shaped lock beam 101, a piston block 104 is fixedly installed at one end of the connecting round rod 103 away from the U-shaped lock beam 101, a docking cavity 105 is opened at the top of the two lock rods 102, an adsorption magnetic block 106 is fixedly installed on the bottom surface of the docking cavity 105, and the piston block 104 is slidably installed in the docking cavity 105;

[0026] The lock core assembly 2 includes a lock core block 201, a lock hole 202 is provided in the middle of the bottom surface of the lock core block 201, and a through-type socket 203 is provided at both sides of the bottom surface of the lock core block 201;

[0027] The docking assembly 3 includes a docking plate 301, and a through sliding hole 302 is opened on both sides of the top surface of the docking plate 301. A crimping groove 303 is opened in the middle of the front side of the docking plate 301. An outward-expanding guide opening 304 is provided at the front of the crimping groove 303. A No. 1 magnetic patch 305 is fixedly installed on the inner surface of the crimping groove 303.

[0028] In this embodiment, the key assembly 4 includes a key 401, and a No. 2 magnetic patch 402 is fixedly installed on the bottom back of the key 401. The key 401 is divided into a head and a tooth portion. The head of the key 401 is adsorbed and installed in the crimping groove 303. Since the guide opening 304 is larger than the head of the key, the head of the key 401 can be easily pressed into the guide opening 304. After pressing in, the lower half of the head of the key 401 can be easily pressed into the crimping groove 303 under the guidance of the guide opening 304. After pressing in, under the adsorption action of the No. 1 magnetic patch 305 and the No. 2 magnetic patch 402, the head of the key 401 will be connected to the crimping groove 303.

[0029] A flat plate is fixedly installed on the top surface of the lock core block 201, and an outward-expanding docking bell mouth 204 is opened on both sides of the top surface of the flat plate.

A reinforcing sleeve 107 is fixedly sleeved on the top of the rod bodies of the two locking rods 102, and a locking portion 108 is provided in the middle of the rod bodies of the two locking rods 102. A limiting ring 109 is threadedly installed on the bottom surface of a telescopic locking rod 102 to prevent the docking assembly 3 from detaching from the rod body of the locking rod 102.

[0032] During use, when unlocking operation is required, the key can be taken out, and then the head of the key 401 is aligned with the guide opening 304. Since the guide opening 304 is larger than the head of the key, the head of the key 401 can be easily pressed into the guide opening 304. After pressing in, the lower half of the head of the key 401 can be easily pressed into the crimping groove 303 under the guidance of the guide opening 304. After pressing in, under the adsorption action of the No. 1 magnetic patch 305 and the No. 2 magnetic patch 402, the head of the key 401 will be connected to the crimping groove 303. After connection, the docking plate 301 is manually pushed. The movement of the docking plate 301 can drive the key 401 to move and conveniently insert it into the lock hole 202 of the lock core block 201, thereby facilitating the user to quickly and conveniently insert the key into the lock hole 202.

[0033] At the same time, the size of the U-shaped lock can be adjusted according to actual needs. Specifically, the position of the piston block 104 in the docking cavity 105 can be manually controlled to control the length of the connecting round rod 103 protruding from the docking cavity 105, and then the length of the rod body on both sides of the lock body assembly 1 can be conveniently adjusted, so that the size of the U-shaped lock can be conveniently adjusted according to actual needs.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
