Abstract

A key direct-open type separate combination theft-proof lock, comprises a front lock head(1), and back lock head(7), a lock body(6) and a balance wheel(9) in the lock body, a lock plunger promoting mechanism, in which the front and the back end of the front lock head (1) are penetrated by a key hole of the front lock head (1); a clip hole of the balance wheel(9) is aligned with the key hole of the front lock head (1); the key can directly enter into the clip hole of the balance wheel(9) through the key hole of the front lock head. With advantages of reasonable design, simple structure, easy practice and low costs, since the lock head is indirectly connected with the balance wheel, the utility model greatly improves the theftproof performance and applies to various situations for theftproof.

Description

Key straight-opening type split combination theftproof lock

Technical field

The utility model relates to a kind of lockset, the key straight-opening type split combination theftproof lock that particularly a kind of sheet that do not link connects.

Background technology

In the existing theftproof lock, the split blocking lock is wherein mainly a kind of, and it utilizes the tapered end core to drive the interlock sheet, and the interlock sheet drives escapement, finishes lock and unblank many by escapement.Relatively be typically the theftproof lock that is used to be embedded in the door, its tapered end links up by interlock sheet and lock body, and an inner lock head is arranged on the lock body, and two tapered ends all have the escapement that is mated, and on the two escapement outer rims shifting block are arranged, and can lock and unblank with the inside from the outside respectively.The tapered end that links up by interlock sheet and lock body wherein, its tapered end core front end connects the interlock sheet, the interlock sheet other end is stuck in the hole clipping of escapement, insert key, the tapered end core drives the interlock sheet and rotates, and the interlock sheet drives the escapement that is mated and rotates, and the shifting block on the escapement is just stirred the pushing mechanism in the lock body, the locking bolt move left and right, thus realize locking and unblanking in the outside, room.This theftproof lock, since the tapered end core of tapered end by the interlock sheet directly and escapement be linked together, as long as the rotational lock head core just can be opened lock easily, theftproof performance is not ideal enough, the interlock sheet connects bad with escapement or comes off, can cause and to open, bring inconvenience, influence life, work and mood to people.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved key straight-opening type split combination theftproof lock is provided, and improves theftproof performance, is convenient for people to use.

The purpose of this utility model can realize by following technical measures: this theftproof lock comprises escapement, the locking bolt pushing mechanism in forward and backward tapered end, box body and the box body, the keyhole of front lock head penetrates the front lock head rear and front end, the hole clipping of escapement and the keyhole of front lock head align, the keyhole that key passes front lock head can directly stretch into the hole clipping of escapement, insert key turns, key while with lock core and escapement rotate, shifting block on the escapement is just stirred the pushing mechanism in the lock body, the locking bolt move left and right realizes locking and unblanking.

The utility model is reasonable in design, adopts tapered end and the split type structure of lock body, and the sheet that will link originally drives escapement and rotates, change with key directly driving into, when with other instrument rotational lock head core, because tapered end does not directly connect with escapement, therefore escapement does not just rotate, lock does not just leave, and adopts technique scheme, and theftproof performance improves greatly, it is simple in structure, implement easily, cost is low, is applicable to the antitheft of various occasions.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, this theftproof lock comprises front lock head [1], escapement [9] in box body [6] and the box body, the locking bolt pushing mechanism, the one back tapered end [7] that is connected as a single entity with it is arranged on lock body [6], front lock head [1] is embedded in the door [12], be fixed on the door [12] by fixed head [13], box body [6] is installed in fixed head [13] back, box body [6] has a base plate [10], escapement [9] is installed on the base plate [10], the keyhole of front lock head [1] penetrates front lock head [1] rear and front end, the keyhole of the hole clipping of escapement [9] and front lock head [1] aligns, keyhole on the front lock head [1] is worn the hole clipping of straight-through escapement [9], key [2] can pass in the hole clipping of the escapement [9] that keyhole directly stretches into, insert key [2] and rotate, key [2] drives tapered end core [3] simultaneously and escapement [9] rotates, and the shifting block [8] on the escapement [9] is just stirred the pushing mechanism in the lock body [6], the locking bolt move left and right realizes locking and unblanking.The keyhole of front lock head [1] is preferably made concavo-convex, wavy or labyrinth-like, the hole clipping of escapement [9] can be made the labyrinth-like more more complicated than keyhole, that size is littler, and can between the hole clipping of the keyhole of front lock head [1] and escapement [9], a movable flashboard be set, after closing, others can't stretch in the hole clipping from keyhole with any instrument, lock then can't be opened, thereby improves theftproof performance better.

Be provided with the elastic positioning machine structure in escapement [9] outside, the elastic positioning machine structure is made up of spring [5] and ball [4], spring [5] presses ball [4], and the elastic positioning machine structure is fixing by sheath [11], and escapement [9] can rotate in sheath [11], in escapement [9] appearance one recess is arranged, when escapement [9] when turning to locking state, recess is fallen ball [4] position, plays the role of positioning, thereby in the time of can guaranteeing to transfer to key [2], the keyhole of front lock head [1] is corresponding with the hole clipping of escapement [9].

Claims (2)

1, a kind of key straight-opening type split combination theftproof lock, comprise escapement [9], locking bolt pushing mechanism in forward and backward tapered end [1], [7], lock body [6] and the lock body, the keyhole of its feature front lock head [1] penetrates front lock head [1] rear and front end, the keyhole of the hole clipping of escapement [9] and front lock head [1] aligns, and the keyhole that key passes front lock head directly stretches into the hole clipping of escapement.

2, theftproof lock according to claim 1 is characterized in that between the hole clipping of the keyhole of front lock head [1] and escapement [9] a movable flashboard being set.
