Abstract

A double closing core insert tapered end comprises lock bodies, lock cores, a force gear and a key, the two sides of the force gear are provided with one lock body respectively and fixedly combined by a lock beam through screws, each lock body is provided with a lock and a lock core sleeve. The utility model is characterized in that: a clutch is arranged on the force gear and consists of two clutch boxes, a clutch spring and a hollow shaft, wherein, each clutch provided with a tower spring and a poke block is arranged in series on the hollow shaft, the two sides of the clutch is arranged on the lock body. When the clutch spring is compressed, the left and right poke blocks can mesh with each other; thereby, when inserted from lock hole inside the door and rotated in the circumstance that the door lock is closed, the key can be inserted from the lock hole outside the door and rotated to make the force gear rotate by the effort of the clutch; thereby, the aim of opening the door lock can be realized.

Description

The pairing inserting-core lock

Technical field

The utility model relates to a kind of inserting-core lock, is applicable to be installed on all kinds of mortise door locks.

Background technology

Mortise door lock is one of daily the most widely used lockset, the mortise door lock of different size, the specification of the inserting-core lock that mates also is Protean, but common characteristic all is the overall fixed formula, also exist a shortcoming to be in addition: after key inserts door inner lock head hole retrotorsion certain angle, in tapered end hole outdoors, insert key again and but can't reverse the unlatching door lock, so just bring very big inconvenience to people.

Summary of the invention

Goal of the invention of the present utility model is the problem that overcomes the technical deficiency of above-mentioned existence, provides a kind of no matter the key in the lockhole reverses and inserting the pairing inserting-core lock that key also can be opened smoothly in the lockhole outdoors again after arbitrarily angled in the door.

Its technical design scheme: it is by lock body, lock core, thumb wheel and key constitute, employing respectively is provided with a lock body in the thumb wheel both sides, at joint contiguous block is set, by lock bridge lock body is combined, be provided with lock core in each lock body, it is characterized in that, be provided with a clutch in the thumb wheel, it is by an identical left side, right two clutch retainers, clutch spring and hollow shaft are formed, a left side, right clutch box branch is located at clutch spring both sides, and go here and there with the clutch spring and to be contained on the hollow shaft, be provided with a tower spring and a shifting block in each clutch retainer, end face on the shifting block radially is provided with a rib hilllock, makes two rib hilllocks on the shifting block can be interior, outer key is meshing with each other when inserting, and reaches can stir thumb wheel when reversing key and open door lock.

Described lock core, be provided with 4 row 20 groups of cross arrangements the pellet shot from a slingshot hole.

Described key, according to the pellet shot from a slingshot hole that is provided with on the lock core, its working portion is meshed together by two cylindric bonding jumpers, two-sidedly is provided with identical pellet shot from a slingshot nest, can two-sidedly use.

Its beneficial effect is: pairing inserting-core lock of the present utility model is provided with a clutch owing to having adopted in thumb wheel, under the key effect, control clutch by clutch and reach the purpose of opening door lock, simultaneously, in lock core, be provided with the pellet shot from a slingshot hole of 20 groups of cross arrangements of 4 rows, the confidentiality of tapered end and the difficulty of technology unlocking have been increased, and the key of respective design adopts two-sided use, can reduce the service wear of key greatly, increases the service life.

The specific embodiment

1-is shown in Figure 2 with reference to the accompanying drawings, pairing inserting-core lock of the present utility model is to realize like this, lock core cover 3 is housed in lock body 1, in the lock core cover 3 lock core 4 is housed, pellet shot from a slingshot 14, following pellet shot from a slingshot 13 and spring 12 are housed in the pellet shot from a slingshot hole of lock core cover 3 and lock core 4, lock core 4 external port and anti-drilling sheet 5 riveteds, alignment pin 6 is fixed on lock core cover 3 in the lock body 1; Described clutch 8, constituted by two clutch retainers 81, clutch spring 84 and hollow shaft 85, be provided with a tower spring 83, a shifting block 82 in each clutch retainer 81, clutch spring 84 is set between two clutch retainers, string is contained in hollow shaft 85 and gets final product so together, be assembled into subsequently in the thumb wheel 9 and contiguous block 2 together and be embedded in the middle of two lock bodies 1, be whole by lock bridge 10 usefulness screws 7 fixed combination at last, at this moment, clutch is under the clutch spring action, and two clutch retainers are in released state; Described key 11, its working portion are to be meshed together by two cylindric bonding jumpers, two-sidedly are provided with identical pellet shot from a slingshot nest, can two-sidedly use.

Its operating principle, after key 11 inserts from door inner lock head hole, force inboard clutch retainer 81 to combine with thumb wheel 9, make thumb wheel 9 produce group commentaries on classics drive dead bolt slip and pin door lock along with the lock core rotation, at this moment, when from tapered end hole outdoors, inserting same key again, force outside clutch retainer inwardly to push, the clutch spring is compressed, in, the shifting block of outer both sides is meshing with each other, and along with the rotation of outside lock core, drives 9 groups of commentaries on classics of thumb wheel like this, again open door lock, thus solved originally door lock pin and interior hand hay cutter key continue to insert and reverse after cause stuck and problem from opening outdoors.
