Abstract

The utility model relates to a push-pull lock core, in which a lock-tongue is provided with a plurality of slide ways forming a certain tilt angle with the axis of the lock-tongue, and a key is provided with the same number of wedge blocks which can slide in the slide ways of the lock-tongue; the axis of the lock-tongue is perpendicular to the axis of the key, and the sum of the included angle of the slideway and the axis of the lock-tongue and the included angle of the axis of the key and the wedge block is a right angle. When the lock-tongue is provided with four slide ways, the mutual opening rate is less than 0.05%.

Description

The push-and-pull lock core

The utility model provides a kind of push-and-pull lock core, belongs to the anti-theft locking technology.

Lockset is people's daily life and the indispensable safety protective toolses of department such as building, car a piece of wood serving as a brake to halt a carriage, safety and finance.Its lock core of lockset of domestic production at present all is pellet shot from a slingshot a---rotational structure, its shortcoming is that complex structure, intensity are low, poor rigidity, easily sled is dialled (lock core is positioned at the surface that is unlocked), is not able to bear strong corrosion, and especially machine-made key causes the lockset mutual opening rate to be difficult to guarantee 0.2% standard value.

At the deficiency of lock cylinder, the purpose of this utility model provides that a kind of mutual opening rate is low and simple in structure, intensity is high, good rigidly, be difficult for sled and dial, and lock core is away from the surface that is unlocked, a kind of push-and-pull lock core of being able to bear strong corrosion.

Above-mentioned purpose of the present utility model realizes by following technical measures:

This lock core is made up of key and dead bolt.Setting and dead bolt axis are a plurality of chutes at certain inclination angle on the dead bolt, then dispose the voussoir of the same number that can in the dead bolt chute, slide on the key, dead bolt axis and key axis are vertical setting, and the angle sum of the angle of chute and dead bolt axis and key axis and voussoir is the right angle.

During work, dead bolt contacts with on the key several little inclined-planes, utilizes friction between the inclined-plane that key thrust is converted into axial force under the effect of key thrust and promotes dead bolt motion, the process of finishing the work.

Tooth number has been formed in the variation of factors such as several little inclined-plane its spacings and bevel angle.When 4 chutes were set on the dead bolt, its mutual opening rate was not more than 0.05%.

With the lockset of this lock core composition have simple in structure, intensity is high, good rigidly, be difficult for that sled is dialled (lock core is away from the surface that is unlocked) and distinguishing feature such as be able to bear strong corrosion, and can become the regeneration product of cylinder lock set.

Dead bolt can be made of 1-2 piece slide block.When two slide blocks were set, the chute inclination angle can be inequality, when one group of chute inclination angle greater than 90 °, can make two slide blocks be different directions and move.

Accompanying drawing is the aufbauprinciple schematic diagram of push-and-pull lock core.Wherein Fig. 1 is a front view, and Fig. 2 is the A-A view of lock core shown in Figure 1, and Fig. 3 is the B-B sectional view of lock core shown in Figure 1, Fig. 4 be Fig. 1 the C-C sectional view of lock core.Below in conjunction with accompanying drawing,, further narrate technical characterictic of the present utility model by most preferred embodiment.

The push-and-pull lock core is made up of dead bolt 2 and key 1.Dead bolt 2 is that two slide blocks that have the different spacing chute constitute.1 of key has two groups and the different spacing chute 3 corresponding voussoirs 4 that are provided with.Voussoir is to the inclination alpha of key axis ₂Sum is 90 °.Dead bolt and key are and are arranged vertically.

In the present embodiment, little voussoir is the duty setting that continues.

Claims

1. push-and-pull lock core, form by key and dead bolt, it is characterized in that on the dead bolt being provided with and the dead bolt axis is a plurality of chutes at certain inclination angle, then dispose the voussoir of the same number that can in the dead bolt chute, slide on the key, dead bolt axis and key axis are vertical setting, and the angle sum of the angle of chute and dead bolt axis and key axis and voussoir is the right angle.

2. push-and-pull lock core according to claim 1 is characterized in that dead bolt 2 is that two slide blocks that have the different spacing chute constitute, and little voussoir is the duty setting that continues.
