CN2695567Y - Locking mechanism of wirerope lock - Google Patents

Abstract

The utility model relates to a locking mechanism of a wirerope lock, comprising a lock head body and a splicing foot. The lock head body comprises an inner case, a lock core case, a lock core and a zinc case. The zinc case is provided with a splicing hole. The lock core is movably assembled in the lock core case. The locking steel ball passes through the zinc case to cooperate with the splicing foot. The splicing foot is provided with an upper locking groove and a lower locking groove. The front end of the lock core extends to connect with a driving plate. A torsion spring is connected between the driving plate and the lock core case. The driving plate is provided with two driving feet which are clipped between the inner case and the zinc case. Wherein, one driving foot cooperates with the locking steel ball. The other driving foot directly cooperates with the upper locking groove on the splicing foot. The utility model overcomes the defect that the common locking mechanism of wirerope locks of prior art all adopt a structure of a single direction locked and the locked reliability is poor. With the detailed design, the upper locking groove and the lower locking groove on the splicing foot are locked by the locking steel ball and the driving plate. Dual safety is realized. The utility model has the advantages of a compact structure, strong anti-theft performance and high reliability.

Description

The steel cable lock locking mechanism

Affiliated technical field

The utility model relates to a kind of steel cable lock locking mechanism.

Background technology

Traditional steel cable lock locking mechanism, the general structure that all adopts the single direction locking, the reliability of its locking is relatively poor, and safety factor is low.

Summary of the invention

In order to overcome the structure that ordinary steel cable lock locking mechanism all adopts single direction to lock in the prior art, the problem that the reliability of its locking is relatively poor, the utility model provides a kind of steel cable lock locking mechanism, and compact conformation, the theftproof performance of this steel cable lock locking mechanism is strong, reliability is high.

The technical scheme that its technical problem that solves the utility model adopts is: comprise tapered end and inserting foot, comprise inner casing in the tapered end, lock core shell, lock core and zinc can, zinc can is provided with spliced eye, the lock core activity is assemblied in the lock core shell, locking steelball passes zinc can and matches with inserting foot, be provided with on the inserting foot, following lock slots, the front end extension of lock core is connected with dial, be connected torsion spring between dial and the lock core shell, dial is provided with two pin of dialling that are installed between inner casing and the zinc can, wherein one group of pin matches with locking steelball, and another group pin upper locking groove direct and on the inserting foot matches.

The utility model is by above-mentioned specific design, broken away from the structure of the traditional single direction that steel cable lock adopted locking, lock upper and lower lock slots on the inserting foot simultaneously by locking steelball and dial, thereby realize dual fail-safe, have compact conformation, theftproof performance is strong, reliability is high 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 A-A sectional view of Fig. 1.

Fig. 3 is the structural representation under unlocking condition.

As shown in the figure, the utility model comprises tapered end 1 and inserting foot 2, comprise inner casing 3 in the tapered end 1, lock core shell 4, lock core 5 and zinc can 6, zinc can 6 is provided with spliced eye 7, lock core 5 activities are assemblied in the lock core shell 4, locking steelball 8 passes zinc can 6 and matches with inserting foot 2, be provided with on the inserting foot 2, following lock slots 9a, 9b, the front end extension of lock core 5 is connected with dial 10, be connected torsion spring 9 between dial 10 and the lock core shell 4, dial 10 is provided with two group pin 11 that are installed between inner casing 3 and the zinc can 6, and wherein one group of pin 11 matches with locking steelball 8, and another group pin 11 upper locking groove 9a direct and on the inserting foot 2 match.When closing lock, inserting foot 2 inserts in the spliced eye 7, and torsion spring 9 drives dial 10 and rotates, the one group of pin 11 pushes following lock slots 9b on the inserting foot 2 with locking steelball 8, simultaneously, another group pin 11 on the dial 10 also blocks the upper locking groove 9a on the inserting foot 2, thereby realizes the dual fail-safe locking.

Claims (1)

1, a kind of steel cable lock locking mechanism, comprise tapered end and inserting foot, comprise inner casing in the tapered end, lock core shell, lock core and zinc can, zinc can is provided with spliced eye, the lock core activity is assemblied in the lock core shell, locking steelball passes zinc can and matches with inserting foot, it is characterized in that: on inserting foot (2), be provided with, following lock slots (9a, 9b), the front end extension of lock core (5) is connected with dial (10), be connected torsion spring (9) between dial (10) and the lock core shell (4), dial (10) is provided with two group pin (11) that are installed between inner casing (3) and the zinc can (6), wherein one group of pin (11) matches with locking steelball (8), and another group pin (11) upper locking groove (9a) direct and on the inserting foot (2) matches.
