Description

Sided lock of safety door

Technical field

The utility model relates to lock technology field, especially relates to a kind of sided lock of safety door.

Background technology

Along with the raising of people's living standard and becoming increasingly abundant of material life, prized up-proof door obtains very big popularization.Accordingly, the pick-proof performance of people to prized up-proof door is had higher requirement.For this reason, the lockset on prized up-proof door must have enough powerful function.Such as, the lockset on many prized up-proof doors comprises master lock and the limit lock of interlock mutually.Wherein, this master lock comprises the lock core inserted for key, and the interlock of this lock core has master lock hook, and after this lock core is rotated by key actuated, this lock core drives the slip on this master lock hook generation above-below direction; This limit lock comprises housing, the slide plate that can horizontally slip is provided with in this housing, the left end of this slide plate is fixed with the dead bolt that can stretch out in this hull outside, simultaneously, the limit latch hook that can slide up and down also is provided with in this housing, this limit latch hook is fixed with a transverse slat extended to the right, this transverse slat is linked in this master lock hook by a rigid link.And, be articulated with a plate that can rotate by the first pivot in this housing.This plate is provided with one first shifting block and one second shifting block.The line of this first shifting block, the second shifting block, the first pivot is triangular in shape.And this linkage board is provided with the pulling hole snapped in for this first shifting block, and this second shifting block is stuck in this interlock hole, this interlock hole width in the vertical direction width equaled on the diameter of this second shifting block, left and right directions is greater than the diameter of this second shifting block.That is, after this master lock hook slides up and down, this transverse slat drives this transverse slat to slide up and down, and this transverse slat drives this slide plate to horizontally slip, and then realizes stretching out and retracting of this dead bolt.So, the theftproof performance of this prized up-proof door is made to obtain significant increase.

But, such limit lock very easily also exist noise more greatly, sensitive not, and halfway phenomenon of locking.

Utility model content

For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of sided lock of safety door, it have noise little, be quick on the draw, and feature comparatively thoroughly of locking.

To achieve these goals, the technical scheme that the utility model adopts is: sided lock of safety door, comprise the housing be fixed on prized up-proof door, the slide plate that can horizontally slip is provided with in this housing, the left side of this slide plate is fixed with dead bolt, simultaneously, the linkage board that can slide up and down is provided with in this housing, at least 1 in-line gears is provided with in described housing, in-line gears comprise the first gear and the second gear that are coaxially fixed together, simultaneously, the side, the right of this slide plate is fixed with the horizontal rack along left and right trend, the avris of this linkage board is provided with the perpendicular tooth bar vertically moved towards, and, this horizontal rack engages this first gear, this perpendicular tooth bar engages this second gear.

The avris of described linkage board is provided with cross bar.

The avris of the right and this cross bar that are positioned at this slide plate in described housing is provided with reference column.

On described reference column, cover has cylinder.

The number of teeth of described first gear is less than the number of teeth of the second gear.

Adopt after said structure, the utility model compared to the prior art advantageously: noise is little, be quick on the draw, and it is comparatively thorough to lock.Sided lock of safety door of the present utility model is rotated by perpendicular rack drives in-line gears, and in-line gears drive slide plate to move left and right afterwards, and then realize stretching out and retracting of dead bolt.Due to comparatively smooth and easy during gear drive, thus noise is less, and the moment of torsion of gear drive institute loss is less, and the reaction that limit is locked is comparatively sensitive, and the phenomenon that there will not be dead bolt not in place.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is that the master of the sided lock of safety door of embodiment of the present utility model looks phantom drawing;

Fig. 2 is the front view of slide plate of the present utility model;

Fig. 3 is the front view of linkage board of the present utility model;

Fig. 4 is the front view (amplifying relative to Fig. 1) of in-line gears of the present utility model.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 to Fig. 4: sided lock of safety door, comprises the housing 10 be fixed on prized up-proof door.Be provided with the slide plate 20 that can horizontally slip in this housing 10, the left side of this slide plate 20 is fixed with the dead bolt 21 that can extend out to this housing 10 outside left.That is, after this dead bolt 21 stretches out, realize lock, retract after realize unblanking.Meanwhile, the linkage board 30 that can slide up and down is provided with in this housing 10.Master lock interlock on this linkage board 30 and prized up-proof door.Such as, the avris of this linkage board 30 is provided with cross bar 31.The master lock hook of master lock of this cross bar 31 for being linked on this prized up-proof door by rigid link.That is, after this master lock hook moves up and down, this linkage board 30 is driven to move up and down by this cross bar 31.

Further say, be provided with at least 1 in-line gears in this housing 10, in-line gears comprise the first gear 41 and the second gear 42 be coaxially fixed together.Meanwhile, the side, the right of this slide plate 20 is fixed with the horizontal rack 22 along left and right trend, and the avris of this linkage board 30 is provided with the perpendicular tooth bar 32 vertically moved towards.And this horizontal rack 22 engages this first gear 41, this perpendicular tooth bar 32 engages this second gear 42.That is, after this linkage board 30 moves up and down, drive this second gear 42 to rotate by this perpendicular tooth bar 32, this first gear 41 rotates then, drives this slide plate 20 to move left and right by this horizontal rack 22.Like this, after gear transmitting torque, the noise that this limit is locked is less, comparatively sensitive, and dead bolt is easy to put in place.

The first gear 41 on aforementioned in-line gears can be identical with the specification of the second gear 42, is two parts up and down of a gear then.Optimize, the number of teeth of this first gear 41 is less than the number of teeth of the second gear 42.So, make the transmission of moment of torsion more smooth and easy.

The avris of the right and this cross bar 31 that are positioned at this slide plate 20 in this housing 10 is provided with reference column 50.On this reference column 50, cover has cylinder 51.Like this, avoid this slide plate 20 too to move right, and force this horizontal rack 22 can engage preferably with this first gear 41.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
