Description

Technical Field

[0001] The utility model relates to the technical field of locks, and more specifically, to a riot-proof U-shaped lock. Background Art

[0002] The U-shaped lock includes a U-shaped locking ring and a lock body at the bottom. The two ends of the locking ring are respectively a locking end and a movable end, and both are inserted into the lock body. When in use, a lock core and a dial wheel structure are arranged in the lock body to lock the locking end of the locking ring, and the movable end slides with the lock body. When the locking end is unlocked, the sliding of the movable end in the lock body can be used to separate the locking end from the lock body to achieve the purpose of unlocking. For the existing common U-shaped lock, after the lock core is violently damaged, the locking end can be quickly unlocked by sliding the movable end. This results in poor performance of the lock against violent damage and low safety performance, which affects the quality of use of the lock. Based on this problem, the present application proposes a riot-proof U-shaped lock. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a riot-proof wide U-shaped lock with high structural strength and long service life.

[0004] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a riot-proof U-shaped lock, comprising a lock ring and a lock body, wherein the two ends of the lock ring are respectively a movable end and a locking end, the lock body is provided with a movable cavity and a locking cavity, the locking cavity is provided with a lock core structure and a thumbwheel structure, the thumbwheel structure comprises a thumbwheel sleeve and a thumbwheel block, the locking end is provided with a locking groove adapted to the thumbwheel block, the thumbwheel sleeve is provided with a locking assembly, the rear end of the locking assembly extends to the outside of the thumbwheel sleeve and conflicts with the bottom wall of the locking cavity, a spring is provided between the rear end of the locking assembly and the bottom wall of the locking cavity, and the other end extends to conflict with the lock core structure, a telescopic clamp is also provided on the outer wall of the locking assembly, a through opening is provided on the inner wall of the thumbwheel sleeve, and a clamping groove corresponding to the position of the through opening is provided on the side wall of the locking groove.

[0005] The utility model is further configured as follows: a connecting groove connecting the locking groove and the movable groove is provided in the lock body, a limiting groove is provided at the opening of the connecting groove corresponding to the movable end, a through-opening 2 is provided at the opening of the other end of the limiting groove corresponding to the dial sleeve, a push rod is provided on the outer wall of the locking assembly, the push rod extends into the connecting groove after passing through the through-opening 2, a limiting block is provided at one end of the connecting groove corresponding to the limiting groove, and the push rod conflicts with the limiting block.

[0006] The utility model is further configured as follows: a first inclined surface is arranged at the end of the push rod, a second inclined surface is arranged on the limit block, and the first inclined surface conflicts with the second inclined surface.

[0007] The utility model is further configured as follows: a telescopic groove is provided on the outer wall of the locking assembly, the telescopic clamp is located in the telescopic groove, the telescopic clamp includes a sliding member and a second spring, and the second spring drives the end of the sliding member to move out of the telescopic groove and contact the inner wall of the dial sleeve.

[0008] By adopting the above technical solution and adding a locking assembly structure, when the lock core structure is violently damaged and broken, the telescopic clamp on the locking assembly will be displaced and cooperate with the clamping groove on the inner wall of the locking groove, causing the dial wheel structure to be unable to rotate, and the lock cannot be unlocked, thus playing a role in preventing riots. At the same time, a push rod and a limit block structure are added. When the locking assembly is displaced, the push rod will be displaced, and the push rod will push the limit block to move. The limit block is clamped in the movable end to limit the movement of the movable end, which also plays a role in preventing the lock from opening. Further improve the safety performance of the lock. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Reference Figures 1 to 4 The utility model is further described in detail.

[0015] A riot-proof U-shaped lock comprises a lock ring 1 and a lock body 2, wherein the two ends of the lock ring 1 are respectively a movable end 10 and a locking end 11, the lock body 2 is provided with a movable cavity 20 and a locking cavity 21, the locking cavity 21 is provided with a lock core structure 3 and a thumbwheel structure 4, the thumbwheel structure 4 comprises a thumbwheel sleeve 40 and a thumbwheel block 41, the locking end 11 is provided with a locking groove 110 adapted to the thumbwheel block 41, the thumbwheel sleeve 40 is provided with a locking assembly 5, the rear end of the locking assembly 5 extends to the outside of the thumbwheel sleeve 40 and conflicts with the bottom wall of the locking cavity 21, a spring 50 is provided between the rear end of the locking assembly 5 and the bottom wall of the locking cavity 21, and the other end extends to conflict with the lock core structure 3, a telescopic clamp 51 is further provided on the outer wall of the locking assembly 5, a through opening 401 is provided on the inner wall of the thumbwheel sleeve 40, and a clamping groove 111 corresponding to the position of the through opening 401 is provided on the side wall of the locking groove 110. A telescopic slot 52 is provided on the outer wall of the locking assembly 5, and the telescopic clamp 51 is located in the telescopic slot 52. The telescopic clamp 51 includes a sliding member and a spring 53. The spring 53 drives the end of the sliding member to move out of the telescopic slot 52 and contact the inner wall of the dial sleeve 40.

[0016] The lock body 2 is provided with a connecting groove 22 connecting the locking groove 110 and the movable groove, the movable end 10 is provided with a limiting groove 100 at the opening corresponding to the connecting groove 22, the dial sleeve 40 is provided with a second through-opening 402 at the opening corresponding to the other end of the limiting groove 100, the outer wall of the locking assembly 5 is provided with a push rod 6, the push rod 6 extends into the connecting groove 22 after passing through the second through-opening 402, the connecting groove 22 is provided with a limiting block 60 at one end corresponding to the limiting groove 100, and the push rod 6 conflicts with the limiting block 60. The end of the push rod 6 is provided with an inclined surface 1 61, and the limiting block 60 is provided with an inclined surface 2 62, and the inclined surface 1 61 conflicts with the inclined surface 2 62.

[0017] Working principle: After the lock core structure 3 is damaged by violence and fractured, the locking assembly 5 moves toward the lock core structure 3 through the driving force of the spring 1 50. When the locking assembly 5 moves, it drives the telescopic clamp 51 to move. The sliding member, driven by the spring 2 53, passes through the through-hole 1 401 of the dial sleeve 40 and is locked in the clamping groove 111. At this time, even if the dial sleeve 40 is rotated in time, it cannot drive the dial block 41 to operate. The lock is in a locked state and cannot be opened even if the lock core structure 3 is destroyed. At the same time, the structure of the push rod 6 is added. When the locking assembly 5 moves, it will drive the push rod 6 to move. The push rod 6 pushes the limit block 60 to be locked in the limit groove 100 of the movable end 10 through the inclined surface 1 61 and the inclined surface 2 62 on the limit block 60. At this time, the movable end 10 on the lock ring 1 is also in a locked state and cannot be operated, which further improves the locked state of the lock and prevents violent opening.
