Abstract

The utility model relates to a U-shaped lock ring locking mechanism which comprises a locking head, a rotating disk, a torsional spring, a locking brake and a lock ring, wherein the end part of a lock core in the locking head is provided with a convex column which is inserted into a hole on the rotating disk and a dialling block is also arranged on the rotating disk to drive the lock brake and the lock ring to match with each other. Both ends of the torsional spring are separately fixed on the locking head and the rotating disk, and the hole on the rotating disk is an irregularly-shaped hole which forms an idle running position relative to the convex column. The utility model overcomes the defects that an ordinary lockset which adopts an automatic inserting and locking structure without using a key in the prior art has poor vibration resisting performance and is easy to unlock when vibrated and impacted by small external force. The utility model changes the straight-line force of a traditional spring into the circumferential force of a torsional spring through the design for making the lockset not unlocked by the mode of vibration, and the lock ring of a U-shaped lock can be locked without the need of using a key. The utility model has the advantages of simple structure, convenient operation and use, strong vibration resisting performance and reliable locking.

Description

U-shape lock lock ring locking mechanism

Affiliated technical field

The utility model relates to a kind of U-shape lock lock ring locking mechanism.

Background technology

The general surely stop of the automatic mortise lock of tradition U-shaped lock lock ring adopts spring structure, and without the automatic mortise lock fixed structure of key, the lockset anti-vibration performance is poor, is subjected to little external force vibration impact lockset and is opened easily; It is good to need with the automatic mortise lock fixed structure of key vibration proof unlatching performance, but uses inconvenient.

Summary of the invention

Poor in order to overcome in the prior art common employing without the lockset anti-vibration performance of the automatic mortise lock fixed structure of key, be subjected to little external force vibration and impact the problem that lockset is opened easily, the utility model provides a kind of U-shape lock lock ring locking mechanism, this U-shape lock lock ring locking mechanism simple in structure, the vibration proof performance is good, easy to use, the locking is reliable.

The technical scheme that its technical problem that solves the utility model adopts is: comprise tapered end, rotating disk, torsion spring, stop and lock ring, lock core end in the tapered end is provided with projection, in the hole on the projection insertion rotating disk, shifting block drive stop also is set on the rotating disk to match with lock ring, the two ends of torsion spring are separately fixed on tapered end and the rotating disk, hole on the rotating disk is an irregularly-shaped hole, and irregularly-shaped hole forms the idle running position with respect to projection.

The end of tapered end is provided with holder, and the two ends of torsion spring are separately fixed on holder and the rotating disk.

The utility model is by above-mentioned specific design, traditional spring straight line force is changed into the force of periphery of torsion spring, lockset can't be unlocked with the mode of vibration, and need not use key just can lock U-shaped lock lock ring, have simple in structure, easy for operation, the vibration proof performance strong, lock reliable advantage.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial exploded view of Fig. 1;

Fig. 3 is the structural representation of rotating disk.

The specific embodiment

As shown in the figure, the utility model comprises tapered end 1, rotating disk 2, torsion spring 3, stop 4 and lock ring 5, lock core end in the tapered end 1 is provided with projection 6, in the hole 7 that projection 6 inserts on the rotating disk 2, shifting block 8 drive stops 4 also are set on the rotating disk 2 to match with lock ring 5, the two ends of torsion spring 3 are separately fixed on tapered end 1 and the rotating disk 2, and the hole 7 on the rotating disk 2 is an irregularly-shaped hole, and irregularly-shaped hole 7 forms idle running position 9 with respect to projection 6.End at tapered end 1 also can be provided with holder 10, and the two ends of torsion spring 3 are separately fixed on holder 10 and the rotating disk 2.Under free state, the effect of torsion spring 3 makes rotating disk 2 be in latched position all the time, thereby stop 4 also is in the lock state.When inserting lock ring 5 lockings, stop 4 is subjected to the insertion force of lock ring 5 to promote rotating disk 2 because rotating disk 2 centers are provided with the idle running position 9 that cooperates with projection 6, rotating disk 2 under the effect of stop 4, need not rotational lock core just can backward rotation, thereby make stop 4 retraction lock bodies; Lock ring 5 inserts and puts in place, and when lock ring groove 11 and stop 4 were corresponding, rotating disk 2 drove stops 4 by shifting block 8 and inserts and implement in the lock ring grooves 11 to lock under the effect of torsion spring 3.

Claims

1, a kind of U-shape lock lock ring locking mechanism, comprise tapered end, rotating disk, torsion spring, stop and lock ring, lock core end in the tapered end is provided with projection, in the hole on the projection insertion rotating disk, shifting block drive stop also is set on the rotating disk to match with lock ring, the two ends of torsion spring are separately fixed on tapered end and the rotating disk, it is characterized in that the hole (7) on the rotating disk (2) is irregularly-shaped hole, and irregularly-shaped hole (7) forms idle running position (9) with respect to projection (6).

2, U-shape lock lock ring locking mechanism according to claim 1 is characterized in that the end of tapered end (1) is provided with holder (10), and the two ends of torsion spring (3) are separately fixed on holder (10) and the rotating disk (2).
