A lock cylinder 05 is arranged in the lock hole 03, a lock plate 06 and a second return spring 07 which are linked with the lock cylinder 05 are arranged on the first lock body 01, and the lock plate 06 moves towards the direction close to the jack 04 under the elastic force action of the second return spring 07. The lock piece 06 includes a lock portion 061, and the second return spring 07 keeps the lock portion 061 inserted into the insertion hole 04 in a state where no external force is applied.

An inner cavity 012 is arranged in the first lock body 01, a sliding block 08 which is linked with the locking piece 06 is arranged in the inner cavity 012, and an embedding opening 013 which is used for embedding the sliding block 08 into the inner cavity 012 is arranged on the surface of the inner cavity 012 facing the second lock body 02. The slider 08 comprises a linkage end 081, a linkage groove 062 which is in limit fit with the linkage end 081 is formed in the lock plate 06, the slider 08 realizes linkage with the lock plate 06 through the cooperation of the linkage end 081 and the linkage groove 062, in the embodiment, the linkage end 081 comprises a convex column 0811 which is arranged in the linkage groove 062 in a penetrating mode and is inserted into the linkage end 081, the convex column 0811 which is arranged independently facilitates assembly of the embodiment, and the convex column 0811 can select a bolt or a pin shaft. The slider 08 is provided with an anti-pry portion 09 separated from the slider 08, the anti-pry portion 09 and the slider 08 are linked through a second projection 082 and a second groove 091 which are arranged on the opposite surface of the anti-pry portion 09 and the slider 08, in the embodiment, the second projection 082 is positioned on the slider 08, and the second groove 091 is arranged on the anti-pry portion 09. Pick-proof portion 09 is arc face 092 towards the face of jack 04, be equipped with on the inner chamber 012 and supply spacing hole 0121 that linkage end 081 wore to establish and supply pick-proof portion 09 to insert the opening 0122 of jack 04, still be equipped with first reset spring 10 on the slider 08, slider 08 is to the direction removal that is close to jack 04 under first reset spring 10's spring action, in this embodiment, first reset spring 10 sets up at inner chamber 012, first reset spring 10 guarantees that pick-proof portion 09 keeps inserting the state of jack 04 when no exogenic action. The lock body is sleeved with a protective frame 11 for protecting the lock body, and the protective frame 11 is provided with a first through hole 111 for inserting a key into the lock hole 03 and a second through hole 112 aligned with the jack 04.

When this embodiment is in the locking state, there is the clearance between the inner wall that convex column 0811 and linkage groove 062 are close to jack 04, the existence in clearance makes the U type lock when passing through the key unblock, locking plate 06 moves to the direction of keeping away from jack 04 earlier alone, after locking plate 06 moves a distance, convex column 0811 and linkage groove 062 are close to the inner wall butt of jack 04, locking plate 06 can drive slider 08 to move together when moving to the direction of keeping away from jack 04 again, in this embodiment, when locking portion 061 withdraws from jack 04 completely, convex column 0811 and linkage groove 062 are close to the inner wall butt of jack 04.

When the inserted rod is not inserted into the jack 04, the locking part 061 and the anti-prying part 09 are in a state of being inserted into the jack 04 under the action of the first return spring 10 and the second return spring 07, when a lock rod needs to be inserted, the locking part 061 and the anti-prying part 09 are kept in a state of being withdrawn from the jack 04 by rotating the lock cylinder 05, after the lock rod is inserted into the jack 04, the key is rotated, the locking part 061 is embedded into the locking groove under the action of the first return spring 10 and the second return spring 07, the anti-prying part 09 abuts against the lock rod, the locking part 061 is relatively fixed with the lock rod in the embodiment, the locking of the U-shaped lock is completed, the anti-prying part 09 can prevent a lawless person from inserting a tool into the space between the jack 04 and the lock rod to damage the locking part 061, and compared with the existing U-shaped lock, the anti-theft performance of the embodiment is better.

The embodiment is provided with an anti-pry portion 09, and the anti-pry portion 09 is located on one side of the locking portion 061 away from the middle of the lock rod. The slider 08 is arranged inside the lock body, so that a lawless person is prevented from damaging the slider 08 and simultaneously enabling the prying-resistant portion 09 to be far away from the hole opening of the jack 04, the prying-resistant portion 09 is increased in difficulty, the arc-shaped surface 092 is attached to the side wall of the lock rod, and the prying-resistant effect of the prying-resistant portion 09 is better.

The protective frame 11 prevents a lawbreaker from separating the first lock body 01 and the second lock body 02 under the locking state of the U-shaped lock, the existence of the first lock body 01 and the second lock body 02 facilitates the slide block 08 to be installed inside the lock body, when the slide block 08 needs to be replaced, the lock rod is firstly separated from the jack 04, then the protective frame 11 is detached, and then the slide block 08 can be replaced by removing the connection state of the first bump 011 and the first groove 021.

The anti-prying portion 09 and the sliding block 08 are produced in a split mode, production efficiency can be improved, the anti-prying portion 09 can be independently replaced under the condition that the anti-prying function cannot be guaranteed due to the fact that the anti-prying portion 09 is bent and abraded by lawless persons, and replacement cost is reduced.

The utility model discloses do not confine the above-mentioned embodiment to, the general technical personnel in this field can adopt other multiple embodiments to implement according to the utility model discloses a, perhaps all adopt the utility model discloses a design structure and thinking do simple change or change, all fall into the utility model discloses a protection scope.
