Wherein, each lock body 30 of the present embodiment is provided therein with a latch bolt assembly 50 engaged with the key cylinder 20, and the key cylinder 20 can drive the latch bolt assembly 50 to engage with the portion of the lock beam 40 inserted into the lock beam hole 31, so as to lock the lock beam 40 on the corresponding lock body 30. The shackle 40 of the present embodiment has a U-shaped structure.

As can be seen from the above, the lock beam 40 of the present embodiment can be assembled to the intermediate lock body 10 through the lock body 30 and locked by the latch bolt assembly 50, so as to achieve the assembly limit between the lock beam 40 and the intermediate lock body 10; that is, the lock body 30 and the middle lock body 10 for the lock beam 40 to be matched on the U-shaped lock of the embodiment can be produced and prepared separately, so that the overall structure of the U-shaped lock can be produced and assembled in a modularized manner, and the U-shaped lock has the advantages of being convenient to produce and process, and improving the utilization rate of materials and the assembly efficiency during manufacturing; in addition, the intermediate lock body 10 is rotatably connected to the lock body 30, so that when the U-shaped lock is used, the intermediate lock body 10 can be driven to freely rotate relative to the lock beam 40 and the two lock bodies 30 according to the use requirement, so that the key 200 can be conveniently inserted into the lock cylinder 20 on the intermediate lock body 10, and the U-shaped lock can be conveniently unlocked.

Specifically, the two lock bodies 30 of the present embodiment are symmetrical to each other with respect to the middle lock body 10, and the key cylinder 20 can simultaneously drive the locking tongue assemblies 50 of the two lock bodies 30 to be in locking engagement with the lock beam 40 or to be unlocked from the lock, so that when the U-shaped lock is operated, the key 200 inserted into the key cylinder 20 is rotated once, and the lock beam 40 can be completely separated from the two lock bodies 30 rotatably connected to the middle lock body 10 or the lock beam 40 is locked to the two lock bodies 30, thereby further facilitating the use of the U-shaped lock.

It should be noted that the two lock bodies 30 of the present embodiment are configured to have the same structure and have the same structural dimensions, so that the two lock bodies 30 can be alternately assembled in the two lock body inner holes 11 of the middle lock body 10, thereby further facilitating the assembly connection of the two lock bodies 30 on the middle lock body 10. Of course, the two lock bodies 30 of the present embodiment are not limited to the illustrated embodiments, and it is obvious to those skilled in the art that the two lock bodies 30 may have different structural dimensions, and accordingly, the two lock body inner holes 11 of the intermediate lock body 10 are also different, and will not be described herein.

In this embodiment, the outer peripheral wall of the lock body 30 of this embodiment is provided with a ring groove 101, the intermediate lock body 10 is provided with a bolt hole 102 matching with the ring groove 101 on the hole wall of the lock core inner hole 11, the lock body 30 can be axially limited with the intermediate lock body 10 by a bolt (not shown) penetrating through the bolt hole 102 and extending into the ring groove 101, so as to realize the assembly connection between the lock body 30 and the intermediate lock body 10, so that the lock body 30 assembled in the intermediate lock body 10 can rotate relative to the intermediate lock body 10 under the limitation of the bolt, and the lock body 30 is prevented from being separated from the intermediate lock body 10.

It should be noted that, the connection manner between the lock body 30 and the intermediate lock body 10 is not limited to that shown in the drawings, and for those skilled in the art, an arc-shaped groove (not shown) may be formed in the outer peripheral wall of the lock body 30, correspondingly, an arc-shaped matching groove (not shown) matching the arc-shaped groove is formed in the hole wall of the lock body inner hole 11 in the intermediate lock body 10, an arc-shaped collar (not shown) is connected to the groove bottom of the arc-shaped groove or the groove bottom of the arc-shaped matching groove through an elastic member (not shown), and the lock body 30 can be axially limited with the intermediate lock body 10 through the arc-shaped collar, which will not be described herein.
