Abstract

A ring-shaped lockset mainly comprises a lock body, a ring-shaped curb chain, a tapered end and a tapered end cover, wherein that lock body comprises at least two layers of lock pin spring and a lock pin. The lock pin spring is arranged in a lock pin spring warehouse, and the lock pin is arranged in a lock pin warehouse. At least six lock pins are utilized for locking the tapered end, the lock pin can not rotate, and the tapered end can be draught out after inserting the key. The lock body of the utility model has the beneficial effects of simple structure, lower manufacturing cost, convenient operation and great burglarproof effect.

Description

A kind of circular lock

Technical field

This novel five metals that belongs to is made the field, more specifically relates to a kind of circular lock.

Background technology

At present the ring lock that uses all exists a lot of weak points, and the one end is a lock body, and the other end is a tapered end, and its principle of unblanking is: after inserting key, the lock core that drives lock body inside by key rotates, and then the lock pin above driving is opened and unblanked.The hidden trouble in public security that lock core very easily causes after destroying can not be effectively antitheft.Though at present the coded lock comparison safety of using remembers that password is cumbersome, password and can not be effectively antitheft also easily is stolen.

Summary of the invention

This novel purpose provides a kind of above-mentioned shortcoming that can overcome, and has strong, a convenient a kind of circular lock that uses of theftproof.

This is novel realizes in the following way: a kind of circular lock, mainly form by lock body, ring lock chain, tapered end, tapered end cover, and it is characterized in that lock body is made up of two-layer lock core spring, lock pin at least.

A kind of circular lock is characterized in that the lock core spring places core spring storehouse, and lock pin places lockpin storehouse.

A kind of circular lock is characterized in that having at least six lock pin locking tapered ends.

A kind of circular lock is characterized in that lock core can not rotate.

A kind of circular lock after it is characterized in that inserting key, can be extracted tapered end out.

This novel beneficial effect is: simple in structure, cost of manufacture is lower, and is easy to operate, good anti-theft effect.

Specific embodiment

As shown in Figure 1, a kind of circular lock mainly is made up of lock body (2), ring lock chain (1), tapered end (5), tapered end cover (3), and lock body (2) is made up of two-layer lock core spring (14) and lock pin (7).Lock core spring (14) places core spring storehouse (13), and lock pin (7) places lockpin storehouse (9).Lock tapered end (5) with ten lock pins (7) during this is novel.Lock core is made up of lock core spring (14) and core spring storehouse (13), and lock core can not rotate.After inserting key (11), can extract tapered end (5) out.

As shown in Figure 1, when this novel lockset is installed, 1, lock core spring (14) puts into core spring storehouse (13), then core spring storehouse (13) pushed the lock body (2) from the left side, by consolidating core spring storehouse pin-and-hole (12) it is being fixed.2, lock pin (7) is as shown in Figure 2 at first put into as shown in Figure 3 lockpin storehouse (9), both put into part lock body as shown in Figure 4 together then, at last this a part of lock body is pushed the lock body (2) from the right side, it is being fixed by solid lockpin storehouse hole (10).3, get final product with lock foreskin (6) the parcel lock body (2) that leaves keyhole, tapered end through hole in advance.

Claims (5)

1. a circular lock mainly is made up of lock body, ring lock chain, tapered end, tapered end cover, it is characterized in that lock body is made up of two-layer lock core spring, lock pin at least.

2. a kind of circular lock as claimed in claim 1 is characterized in that the lock core spring places core spring storehouse, and lock pin places lockpin storehouse.
