Abstract

The utility model relates to a key and lock cylinder which has all-angle insertion and extraction function. The utility model is characterized in that the key is convenient to insert and pull out at any angle of 360 DEG in the circular hole of the lock cylinder. The lock cylinder uses an axial cylinder device, and namely, the axis direction of the cylinder and the axial line of the lock cylinder are parallel. The utility model overcomes the disadvantage that the existing key can only be inserted and pulled out at one angle.

Description

Key and lock cylinder with all-angular insertion and extraction characteristics

Lockmaking technical field under the utility model.

Existing billiards lock structure, pellet shot from a slingshot device all are horizontal, and promptly the axis direction of pellet shot from a slingshot is vertical with the axis of lock core, and pellet shot from a slingshot all is arranged on the upper thread.This plane is by the lock core axis, and the cylinder lock of selling on the market is exactly this structure.The lock core key of therefore planting lock is a sheet type.When plugging, key has only an angle, so just to unblanking and extracting key and cause difficulty.At night and the place that does not have electric light, the particularly old and young invalid grade people freely that unblanks not uses more inconvenient.

The purpose of this utility model provides a kind of key can plug in 360 ° of lock core holes are arbitrarily angled, and opens and closes freely.

The purpose of this utility model is achieved in that because the axis direction of pellet shot from a slingshot becomes parallel lines with the axis of lock core, and the lock core hole of slotting key is circular hole, thus key can plug in 360 ° of lock core holes are arbitrarily angled and switching freely.

Existing key has only the shortcoming of a directed plug angle in lock core, bring the difficult worry that difficulty is pulled out of inserting when unblanking.And key of the present utility model can be in 360 ° of lock core circular holes be arbitrarily angled plug and opening and closing freely, so the utility model is compared with existing key according to arbitrarily angled plug being arranged and opening and closing freely advantage.

Fig. 1 is the main sectional view of the utility model axial cylinder lock core, and Fig. 2 is the utility model, and the left sectional view of axial cylinder lock core, Fig. 3 are the main sectional views of the utility model cylinder key, and Fig. 4 is the right view of the utility model cylinder key.

The axis direction of pellet shot from a slingshot 6 and the axis of lock core 9 are into the axial cylinder device of parallel lines among Fig. 1 of the present utility model and Fig. 2, key is housed in the lock core shell 1 inserts retainer spring 3, and key inserts positioning bead 2.When being inserted, the key of Fig. 3 cooperate location circumferential groove 3 with the purpose that reaches the location and can open and close.Lock opens and closes in pin and the lock core 9 spring 7 is housed, and pellet shot from a slingshot 6; Pellet shot from a slingshot 6 is to adopt common existing pellet shot from a slingshot and spring with marble spring 7.There is a lock core dowel 8 at the lock core center, and lock core 9 is played the role of positioning, and the circumference rotary action.Lock core is stirred flange place 5 and can be designed to be connected with any latch mechanism and be used.Key insertion hole is a circular hole in the lock core of the present utility model.So plug freely during key of the present utility model was can be in 360 ° of lock core circular holes arbitrarily angled.And open and close freely.

The utility model Fig. 3 and Fig. 4, key body 2 ' right-hand member are that cylindrical (locating at tartar 4 ') left end is that a circular hole 1 ' is arranged in the adept handle 6 ' of sheet, and circular hole 1 ' dress key ring is used.Key body 2 ' inserts place in Fig. 1 lock core, and lock opens and closes pin 4 and enters Fig. 3 pin-and-hole 5 ', and tartar 4 ' enters Fig. 1 pellet shot from a slingshot 6 places simultaneously, and first pellet shot from a slingshot and lock core end face are in line, and rotates lock core 4 among Fig. 1 and rotation just reaches the purpose of unblanking through the adept handle 6 ' of sheet.

Claims

1, a kind of full angle plug key, lock core, the lock core integral body of forming by lock core shell, lock core, lock core centralized positioning pin, pellet shot from a slingshot and spring, and also the slotting keyhole in lock core center is circular; The tartar end of key is the garden post, it is characterized in that: the axis direction of pellet shot from a slingshot becomes parallel lines with the axis direction of lock core in the lock core, and above-mentioned key can plug in 360 ° of lock core circular holes are arbitrarily angled.

2, the described lock core of claim 1, its feature also is: there is an alignment pin at the lock core center.

3, the described lock core of claim 1, its feature also is: have a lock to open and close pin in the lock core.

4, the described key of claim 1, its feature also is: key tooth flower cylindrical end circumference has setting circle week groove.

5, the described key of claim 1, its feature also is: key tooth flower end recess has a lock to open and close lockhole.
