Abstract

The utility model discloses a novel mortise lock head, which comprises a lock head shell, a lock cylinder and a lock powertape, wherein corresponding lock head shell marble holes are formed in the lock head shell, and corresponding lock cylinder marble holes are formed in the lock cylinder; marbles and springs are arranged in the lock head shell marble holes and the lock cylinder marble holes; one end of the lock powertape is T-shaped; the lock head shell is provided with a lock cylinder hole; a lock powertape retaining ring is arranged on the inner wall of one end of the lock cylinder hole; an unlocking bump is arranged on the end face of the lock cylinder; after the lock powertape and the lock cylinder are inserted into the same end of the lock cylinder hole, one side of the T-shaped end of the lock powertape is pressed against the lock powertape retaining ring, and the other side of the T-shaped end of the lock powertape is pressed against the end face of the lock cylinder, namely the T-shaped end of the lock powertape is clamped between the end face of the lock cylinder and the lock powertape retaining ring. According to the novel mortise lock head with the structure, a connecting structure of the lock powertape and the lock cylinder is simple, the novel mortise lock head is easy to produce and assemble, the production cost can be lowered, and the market competitiveness of a product can be improved.

Description

A kind of new-type inserting-core lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of mechanical lock tapered end.

Background technology

Mechanical lock tapered end mainly consists of lock shell, lock core, sword iron, lock shell of the prior art is provided with columniform hole, lock core is arranged in lock shell, at the end face of lock core, be provided with the shrinkage pool of indent, one end of sword iron is connected in shrinkage pool by parts such as nut, spacer, springs, or the end face at lock core is provided with U-shaped mouthful, sword iron is connected in U-shaped mouthful by pin, the bindiny mechanism of its lock core of the tapered end of this structure and sword iron is comparatively complicated, produce and assemble comparatively trouble, cause the production of product to rise originally high.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of new-type inserting-core lock of assembling easily, can reducing production costs.

The utility model solves the technical scheme that its technical problem adopts:

A kind of new-type inserting-core lock, comprise lock shell, lock core and sword iron, described lock shell and lock core are respectively arranged with corresponding lock shell marble hole and lock core marble hole, in described lock shell marble hole and lock core marble hole, pellet and spring are installed, one end of described sword iron is T-shaped, described lock shell is provided with lock core hole, and one end inwall of described lock core hole is provided with sword iron baffle ring, and the end face of described lock core is provided with the projection of unblanking.

Described sword iron baffle ring and described lock shell are one-body molded.

One side of the T-shaped end of described sword iron is provided with the breach that the projection of unblanking described in can supplying is passed through.

Described lock shell is provided with the pin-and-hole connecting with described lock shell marble hole, is plugged with a pin in described pin-and-hole, and the end of described spring is against on described pin.
