Abstract

The utility model relates to a car lock capable of preventing forced unlocking. A rotatable lock cylinder which is cylindrical in appearance in the traditional car is changed into a platform lock cylinder which can not rotate and is of a cylinder shape provided with bosses or a multilateral prismatic shape in the appearance, a lock cylinder hole matched with the lock cylinder is also changed into the cylinder shape provided with the bosses or the multilateral prismatic shape, and a lock cylinder interface at junction of an upper marble and a lower marble is a plane. A way of moving forward and backward is adopted in opening and closing of the lock, and a push lock cylinder spring which pushes the platform lock cylinder to move horizontally and a bolt which is linked with the platform lock cylinder are added. After a key is inserted, the platform lock cylinder moves horizontally outward under the action of thrust of the push lock cylinder spring, and the bolt linked with the platform lock cylinder is separated from a lock tongue groove at the side of a lock tongue of the car lock, thus the car lock is unlocked. The key is inserted, the platform lock cylinder is pushed to the end by hands, and then the lock cylinder is pressed and the key is pulled out, thus the car lock is locked. The appearance of the platform lock cylinder is not rotatable, thus no use is realized after a hard alloy key is inserted and forcedly rotated and the car lock can not be unlocked by adopting a forced unlocking method.

Description

The anti-strong lock of driving

Technical field

The utility model relates to a kind of lock, and especially a kind of anti-strong driving that can prevent that the robber from utilizing the carbide alloy key to turn on lock by force locked.

Background technology

At present, in the known lock, because of the lockset external diameter is little, cause down pellet shot from a slingshot weak point and length difference little, size of key is very low, and mutual opening rate is high, and is easy to open by force.The robber utilizes the carbide alloy key to turn on locking method by force: earlier the carbide alloy key is inserted in the lock core keyhole; Rotate with brute force then,, be easy under forceful action, produce destructive the rotation because the short length difference of pellet shot from a slingshot is little and end face has arc; Lock has also just been opened, so be absolutely unsafe.

Summary of the invention

Can turn on the deficiency of lock with the carbide alloy key by force in order to overcome existing lock.The utility model provides a kind of anti-strong lock of driving, and it can thoroughly stop and applies brute force with the carbide alloy key and unblank, thereby greatly improves degree of safety.

The utility model solves the technical scheme that its technical problem adopted: with rotating profile in the existing lock is columniform lock core; The profile that cannot not make into rotatable is that the cylindrical or polygon prismatic platform lock core of boss is arranged, and the lock core hole in the tapered end that is complementary therewith also has boss cylindrical or polygon prismatic instead.Pellet shot from a slingshot intersection lock core interface is the plane up and down; The periphery radian of lock core changes the precision that no longer influences pellet shot from a slingshot; Less lock core also can adopt the following pellet shot from a slingshot than major diameter and length, and billiards diameter has increased intensity, and the pellet shot from a slingshot end face no longer needs radian and improved the pellet shot from a slingshot precision; Following pellet shot from a slingshot length increases the size of key that has promoted lock, more than comprehensively strengthened the degree of safety of this lock.The mode of translation before and after the folding of this lock is adopted, the following pellet shot from a slingshot of platform lock core and the quantity in hole are lacked one than the last pellet shot from a slingshot of lock body and the quantity in hole, promptly cancel the nearly outer end of lock core first following pellet shot from a slingshot and hole.Increase to promote the translation of platform lock core promotion lock core spring, with the latch of platform lock core interlock.After inserting key, this moment, pellet shot from a slingshot no longer locked the platform lock core up and down, and the platform lock core is promoting under the effect of lock core spring thrust, and outwards pellet shot from a slingshot pitch-row of translation leaves, and separated with the dead bolt groove of the dead bolt side of lock with the latch of platform lock core interlock, and lock is opened.In the time of need sealedly being somebody's turn to do lock, inserting key and use hand propelled platform lock core the end of up to, pin lock core dial-out key then, this moment is spring lock fixed platform lock core up and down, and this lock is promptly sealed.Rotatable because of the profile of the platform lock core of this lock for, reverse by force and move lack scope for their abilitiesly so insert the carbide alloy key, this lock can't be opened with the method that brute force is unblanked.

The beneficial effect of the utility model is: can thoroughly stop to turn on lock by force with the carbide alloy key, theftproof performance is good, and simple and reliable for structure.

Do not belong to omit in other partial graph in the lock of the utility model and draw or do not annotate, and the detail section that does not relate to the utility model in the drawn part has been done to simplify or omit.

4. times pellets shot from a slingshot of pellet shot from a slingshot, 5. latches, 6. promotion lock core springs, 7. dead bolt 7a. dead bolt grooves, 8. keys on 1. tapered ends, the 2. platform lock cores 3. among the figure

The specific embodiment

In Fig. 2, be columniform lock core with rotating profile in the existing lock, the profile that cannot not make into rotatable is for there being the columniform platform lock core 2 of boss, and the lock core hole in the tapered end 1 that is complementary therewith also has boss cylindrical instead.Last pellet shot from a slingshot 3 is the plane with following pellet shot from a slingshot 4 intersection lock core interfaces; The periphery radian of lock core changes the precision that no longer influences pellet shot from a slingshot; Less lock core also can adopt the following pellet shot from a slingshot 4 than major diameter and length, and billiards diameter has increased intensity, and the pellet shot from a slingshot end face no longer needs radian and improved the pellet shot from a slingshot precision; Following pellet shot from a slingshot length increases the size of key that has promoted lock, more than comprehensively strengthened the degree of safety of this lock.

In Fig. 1, the mode of translation before and after the folding of this lock is adopted, the following pellet shot from a slingshot of platform lock core 2 and the quantity in hole are lacked one than the last pellet shot from a slingshot of lock body 1 and the quantity in hole, promptly cancel the nearly outer end of lock core first following pellet shot from a slingshot and hole.Increase to release 2 translations of platform lock core promotion lock core spring 6, with the latch 5 of platform lock core 2 interlocks.

In Fig. 1, after inserting key 8, this moment, pellet shot from a slingshot all no longer locked platform lock core 2 up and down.In Fig. 3, platform lock core 2 is promoting under lock core spring 6 thrust, and outwards pellet shot from a slingshot pitch-row of translation leaves, and separates with the dead bolt groove 7a of dead bolt 7 sides of lock with the latch 5 of platform lock core 2 interlocks, and lock is opened.

When needing sealed should the lock, insert key and move at the end (position as shown in Figure 1) with hand propelled platform lock core 2 always, pin lock core then and transfer to key 8, this moment is cylinder lock fixed platform lock core 2 up and down, and this lock is promptly sealed.

Rotatable because of the profile of the platform lock core 2 of this lock for, reverse by force and move lack scope for their abilitiesly so insert the carbide alloy key, this lock can't be opened with the method that brute force is unblanked.

Claims

1. anti-strong a driving locked; It is characterized in that the profile that lock core cannot not processed rotatablely in the lock is that the cylindrical or polygon prismatic platform lock core (2) of boss is arranged; The lock core hole of tapered end (1) of being complementary therewith also has boss cylindrical or polygon prismatic instead, and last pellet shot from a slingshot (3) is the plane with following pellet shot from a slingshot (4) intersection lock core interface.
