Description

Pellet shot from a slingshot, cipher anti theft lock core

The utility model relates to civilian lockset, a kind of specifically pellet shot from a slingshot, cipher anti theft lock core.

Along with the economic construction development, living standards of the people improve, and private property increases, and people have had more requirement to the theftproof performance of lockset, at present, main suitable civilian lockset is a cylinder lock, and cylinder lock has simple in structure, advantage easy to use, but, there is the shortcoming of being opened by MASTERKRY easily in traditional cylinder lock, and theftproof performance is relatively poor, and consumer wants has the lockset of the better cylinder lock type of theftproof performance.

The purpose of this utility model provides a kind of pellet shot from a slingshot, cipher anti theft lock core, and firm, the practical advantage of its tool cylinder lock has increased the numerical ciphers anti-theft measure again, has the double insurance of key encryption sign indicating number, and simple in structure, easy to use.

The purpose of this utility model is achieved in that

A kind of pellet shot from a slingshot, cipher anti theft lock core, its structure comprises lock body, lock core body, lock core and pellet shot from a slingshot, lock core is loaded in the lock core body, on lock core and lock core body mating face, some transverse holes are arranged, the pellet shot from a slingshot of being made up of upper and lower straight pin and spring is housed in the hole, it is characterized in that: its structure also comprises cipher ring, by rotating ring and round pin

It is corresponding with the lock body shoulder hole that the cipher ring cylindrical is stepped cylindrical, and it is poroid corresponding with lock core body cylindrical ladder post that its interior circle is ladder, and be shaped on a semicircular arc pin-and-hole and a rectangle on its less cylindrical end is faced the wall and meditated and protrude piece,

Cylindrical corresponding by the rotating ring cylindrical with the lock body shoulder hole, it is poroid corresponding with lock core body cylindrical ladder post that its interior circle is ladder, be shaped on a semicircular arc pin-and-hole and a rectangle on it is faced the wall and meditated than the imperial palace nose end and protrude piece, and when being somebody's turn to do a contacts side surfaces of the protrusion piece that protrudes piece and cipher ring, described two semicircular arc pin-and-holes align just forms a full circle pin-and-hole;

Its assembly relation is: described cipher ring is installed between lock body and the lock core body with relative by the end face that semi-circle pin holes and rectangle projection are arranged of rotating ring, and its length sum be able to make lock core be fixed in lock core body with turn, lock core body with screw in lock body.

Be shaped on a pin-and-hole on the wall of lock core body away from a side of pellet shot from a slingshot, penetrate tube wall and communicate with keyhole, the position of this pin-and-hole aligns the semicircular arc pin-and-hole center on cipher ring and the passive endless tube wall, and axially displaceable round pin is housed in this pin-and-hole.

The utility model has following actively useful effect:

1. it has kept the design feature of common spring lock, has increased the structural measure of numerical ciphers again, has the double insurance of key encryption sign indicating number, and essence is the combination of pellet shot from a slingshot town and coded lock, has improved the anti-theft capability of lockset.

2. cipher ring can be changed, and improves antitheft confidentiality.

3. simple in structure, with the phase-locked ratio of common spring, cost increases few.

4. easy to use, promote easily.

5. applied widely, can be used for various places such as civilian family door, cabinet door, office door, safe door.
