Abstract

The utility model relates to a mechanical anti-theft lock head, which comprises a lock core, a lock core body, pins, a spring and a connecting pin, wherein at least two rows of pin grooves are provided on the periphery of the lock core; center line of the pin grooves forms an included angle with center point of the lock core; pins are placed in the pin grooves; driver pins and springs are respectively loaded in a correct order behind the pins, and are sealed by steel balls. The utility model thus has simple structure and processes, and is easy to make; besides, since pins are placed in pin grooves of certain angle to and are arranged in a crossed manner, the pins retain the intercrossing state whether the lock core is unlocked or locked, thus the utility model gains enhanced anti-theft capabilities.

Description

The mechanical antitheft lock head

Technical field

The utility model relates to a kind of mechanical antitheft lock head.

Background technology

The product in lockset market roughly is divided into two big classes at present: mechanical type and electronic type.Mechanical tapered end still is a main flow, and mechanical lock head mainly comprises spherical door lock, handle-door lock and mortise door lock.In recent years, in order to improve the theftproof performance of lockset, the lockmaking industry had been developed a large amount of new products, from before the single-row billiard lock core, develop into present many rows lock cylinder, slice, thin piece lock core, rotating piece type automatic lock core etc.But still having some defectives on these lock structures, mainly is complex structure, and pellet shot from a slingshot, slice, thin piece all are exposed to the outside, are opened by existing unlocking tool easily, and theftproof performance is relatively poor.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and the mechanical lock head that theftproof performance is good is used to overcome existing anti-theft lock structure complexity, the problem that technology difficulty is big.

For realizing above purpose, the utility model is except that having comprised lock core, lock core body, pellet shot from a slingshot, spring and connecting pin, and principal character is that the lock core excircle is provided with at least two row's bullet groove, and the bullet groove center line becomes angle with the lock core central point, and pellet shot from a slingshot is placed in this groove; Pack into successively respectively in the pellet shot from a slingshot back tack pellet shot from a slingshot, spring are shut with steel ball then.

For further realizing above purpose, the location is blocked with spring card by lock core shaft in being installed in lock core body.

Advantage of the present utility model is: structure and technology are simple, make easily, because of its pellet shot from a slingshot is to be placed in the bullet groove of certain angle, forms to intersect and put, and no matter lock core is in is opened or lockup state, and its pellet shot from a slingshot all is in crossing condition.Open the key non-rectilinear of tapered end, but interweave in length and breadth, have only key to be inserted into the position, key and top put in place simultaneously, and tapered end just can be opened.It is bigger that other unlocking tools are opened difficulty, increased theftproof performance.The utility model can be used for security door efficiently and the user of door lock has been installed changes tapered end.

Description of drawings

Fig. 1 is the structural representation of utility model

Fig. 2 is the structure A-A sectional drawing of utility model

1 lock core among the figure, 2 lock core bodies, 3 spring cards, 4 covers that are in transmission connection, 5 connecting pins, 6 lock cores, 7 steel balls, 8 tack pellets shot from a slingshot, 9 pellets shot from a slingshot, 10 springs, 11 steel balls.

The specific embodiment

By Fig. 1, Fig. 2 finding, the utility model is made up of lock core 6, lock core body 2, pellet shot from a slingshot 9, spring 10 and connecting pin 5, the end face of lock core 6 and be axially arranged with key, the excircle of lock core 6 is provided with two row's bullet groove, the bullet groove center line becomes 90 ° of angles with the lock core central point, pellet shot from a slingshot 9 is placed in this groove; Reinstall tack pellet shot from a slingshot 8, spring 10 respectively successively in pellet shot from a slingshot 9 back, shut with steel ball 7 then.Lock core 6 axially is installed in the lock core body 2, blocks the location with spring card 3.

It is constant that tapered end is contained in inferior lock core 1 structure of an interior end, and by the cover 4 that is in transmission connection, the pin 5 that is in transmission connection is connected to an integral body with itself and lock core 6.When key enters lock core 6, back down tack pellet shot from a slingshot 8, pellet shot from a slingshot 9, tapered end is in the enable possition, and simultaneously, the key front end withstands connecting pin 5, and makes it move forward certain distance, is in the middle of the connecting pin 5, and the screw key security door is opened.

Claims (2)
