Description

A kind of theftproof lock

Technical field

The utility model relates to a kind of lockset, particularly relate to a kind of lock body and key of comprising, wherein, this lock body comprises lock core, the first pellet shot from a slingshot unit and the second pellet shot from a slingshot unit, this first pellet shot from a slingshot unit and this second pellet shot from a slingshot unit comprise some pellets shot from a slingshot respectively, and this key comprises the first tooth unit and the second tooth unit, wherein, this first tooth unit is corresponding with this first pellet shot from a slingshot unit, and this second tooth unit is corresponding with this second pellet shot from a slingshot unit, further, this first tooth unit is formed by being convexly equipped with at these some double wedges on the key, and the theftproof lock that this second tooth unit is made up of some through holes.

Background technology

As everyone knows, lock class apparatus is as the very general environment that has entered into the daily productive lifes of people of a kind of security protection class device, and it structurally mainly comprises core, pellet shot from a slingshot and spring with regard to general lockset, therefore, no matter lock how inequality of the external form of body and the office of lock in the body, but what bringing into play main effect for the operating principle of lock also is core, pellet shot from a slingshot and spring.When the pellet shot from a slingshot hole of lock body overlapped fully with the pellet shot from a slingshot hole of core, the spring performance elastic force effect in the lock body pellet shot from a slingshot hole upwards ejected the pellet shot from a slingshot in the lock body pellet shot from a slingshot hole.Pellet shot from a slingshot in the lock body pellet shot from a slingshot hole by jacking in the core pellet shot from a slingshot hole.Original pellet shot from a slingshot is upwards pushed up at one time in the core pellet shot from a slingshot hole.Owing to have a long raised line to block in the core keyhole, stop the pellet shot from a slingshot in the core pellet shot from a slingshot hole, pellet shot from a slingshot is not ejected outside the pellet shot from a slingshot aperture, take off out.

When the pellet shot from a slingshot in the lock body pellet shot from a slingshot hole has sticked in the core pellet shot from a slingshot hole, just core is blocked, equaled to block circular object, circular object can't arbitrarily be rotated.At this moment, lock is to be in the keyed state, exactly " having locked " of saying usually.Yet, after stretching key and entering the core keyhole, teeth groove on the key the pellet shot from a slingshot of core pellet shot from a slingshot in also to lower compression, just the pellet shot from a slingshot total head in the core pellet shot from a slingshot hole is fallen, flatten the place, another side aperture in core pellet shot from a slingshot hole, the contact surface of lock body pellet shot from a slingshot aperture (the core pellet shot from a slingshot aperture with), at this moment lock in body pellet shot from a slingshot the hole in all pellets shot from a slingshot owing to by pellet shot from a slingshot in the core pellet shot from a slingshot hole to the effect that presses down, also all be driven plain lock body pellet shot from a slingshot aperture, get back in the lock body pellet shot from a slingshot hole.At this moment, the pellet shot from a slingshot in the lock body pellet shot from a slingshot hole can not stick in the core pellet shot from a slingshot hole, and the pellet shot from a slingshot that is pressed down in the core pellet shot from a slingshot hole can not be depressed in the pellet shot from a slingshot hole that enters the lock body, has not had thing to block circular core in other words.Available then key reverses core and rotates, and then drives the office in the lock body after core rotates, and lock is opened.This is the concrete operating principle of conventional lock.But the situation that the thief utilizes non-original key or simply utilizes strip stealing tool such as steel disc just lockset can be opened easily often takes place in traditional lockset in concrete the use, and this is the major defect for conventional lock.

Summary of the invention

The utility model provides a kind of theftproof lock, and it comprises the dual structure of unblanking, and by this dual structure Design of unblanking, to reach the purpose that improves whole lock body safe antitheft performance.And this is to be main purpose of the present utility model.

To achieve these goals, the technical scheme that the utility model is taked is: a kind of theftproof lock, it comprises lock body and key, this key matches with this lock body, wherein, this lock body comprises lock core, the first pellet shot from a slingshot unit and the second pellet shot from a slingshot unit, and this first pellet shot from a slingshot unit and this second pellet shot from a slingshot unit are successively set in this lock core.

This first pellet shot from a slingshot unit comprises some pellets shot from a slingshot, and each this pellet shot from a slingshot is all corresponding with a marble spring, and further, this marble spring is the corresponding respectively end that is arranged on this pellet shot from a slingshot.

This second pellet shot from a slingshot unit is corresponding with this first pellet shot from a slingshot unit and be arranged in this lock core, and it comprises some pellets shot from a slingshot, and each this pellet shot from a slingshot is all corresponding with a marble spring, and further, this marble spring is the corresponding respectively end that is arranged on this pellet shot from a slingshot.

This key is corresponding with this lock core, it comprises the shank of the key and key bit, wherein, this key bit comprises the first tooth unit and the second tooth unit, wherein, this first tooth unit is corresponding with this first pellet shot from a slingshot unit, and this second tooth unit is corresponding with this second pellet shot from a slingshot unit, further, this first tooth unit is formed by being convexly equipped with at these some double wedges on the key, and this second tooth unit is made up of some through holes, further, each this through hole is all corresponding with a pellet shot from a slingshot of this second pellet shot from a slingshot unit, and the termination of this pellet shot from a slingshot of this second pellet shot from a slingshot unit can be passed in this through hole.

Effect intentionally of the present utility model is: because the utility model structurally comprises lock body and key, wherein, this lock body comprises lock core, the first pellet shot from a slingshot unit and the second pellet shot from a slingshot unit, this first pellet shot from a slingshot unit and this second pellet shot from a slingshot unit comprise some pellets shot from a slingshot respectively, and this key comprises the first tooth unit and the second tooth unit, wherein, this first tooth unit is corresponding with this first pellet shot from a slingshot unit, and this second tooth unit is corresponding with this second pellet shot from a slingshot unit, further, this first tooth unit is formed by being convexly equipped with at these some double wedges on the key, and this second tooth unit is made up of some through holes, by such structure design, the unique design mode of being made up of some through holes by the corresponding relation between this second pellet shot from a slingshot unit and this second tooth unit and this second tooth unit especially reaches the effect of safe antitheft.
