Abstract

The utility model relates to a lock, which is suitable for doors with double wings and can be directly arranged on a door with double wings. The lock is composed of a pinch plate 2, a pinch plate seat 3, an outer lock head 4, an inner lock head 12, a handgrip 17, etc., wherein, the inner lock head 12 and the outer lock head 4 are connected together by a twist handle 13, a twist handle pin 7, a lock sheet 11 and a teleflex 5. The utility model can be unlocked from the inner side and the outer side of the door. When the twist handle 13 is locked into the inner lock head 12, the inner side and the outer side of the door both need to be unlocked by a key 32. Because the outer lock head 4 is also used as a dead bolt, the lock has the advantages of compact structure, strong intensity, convenient use, wide application ranges and good theftproof performance, and the utility model is suitable for doors with double wings such as spring doors, sliding doors, folding doors, etc.

Description

Door lock

The utility model relates to a kind of lockset, particularly is applicable to the lockset of double door.

At present, existing double door locking medium generally adopts the bolt bar to add padlock, the button nose adds padlock, and the closed loop handle adds methods such as chain lock binding, and the above practice is not owing to adopt anti-theft measure, thereby theftproof is poor, use also inconvenience, though occurred many double door door locks with theftproof performance now, these door lock volumes are big, the price height, narrow application range.What for example Hebei produced a kind ofly has an antitheft effect door lock, utilizes ball-type to carry out locking driving the bolt bar by dead bolt, and its actuating quantity is big, operates cumbersomely, is only applicable to timber, and double doors such as aluminium alloy door, sliding door folding door then are difficult to be suitable for.

The purpose of this utility model is exactly that a kind of have antitheft effect, price is low, volume is little, applied widely, easy to use double door door lock will be provided.

The utility model is to realize like this, a kind of double door door lock of forming by handgrip 17, buckle 2, buckle seat 3, outer tapered end 4, inner lock head 12, its difference is that buckle 2 and buckle seat 3 are flexible connection, outer tapered end 4 by the integral telescopic effect is connected pin 7 with turning round by pivoted housing 5 with a thinner end of turning round 13, turn round a thicker end is connected with inner lock head 12 by locking plate 11.

The utility model is that also described outer tapered end 4 is connected with the feather key 8 that play the guiding role by compressing spring 6, and feather key 8 is flexible connection with the block 9 that plays outer tapered end 4 Telescopic Fixed effects, and joining to holding at pivoted housing 5 and block 9 has a breach 10.

Because the utility model adopted the outer tapered end 4 with telescopic action, make inside and outside tapered end connection to 13 by turning round, thereby the structure of door lock is more simple, volume is less, and the mounting screw owing to door lock integral body is not exposed again, thereby high safety, simple and safe operation, applied widely.

Embodiment:

Buckle 2 is 7mm iron plate punching press and smart in twice moulding, it opens and closes end and is made up of the guiding garden arc 34 that play the guiding role and the arc notch 19 of keying effect, with the rotary part of buckle axle 1 be an oblong aperture, to adjust the gap that produces because of the door distortion, buckle 2 is linked together by garden pin 21 by buckle axle 1 and buckle fixed head 20, and fixed head 24 is connected with nut 23 by screw 25 with buckle fixed head 20.Handgrip 17 is a die casting, it can drive buckle axle 1 by handle stem 22 and rotate with buckle 2, make buckle 2 incisions, withdraw from the buckle seat 3, buckle seat 3 is connected with 3 top nuts 28 of buckle seat by screw 27 with lock collar 26, lock collar 26 and inner lock head 12 are die casting, and lock collar 26 is connected by screw 29 with inner lock head 12, and outer tapered end 4 can be flexible in the tube of buckle seat 3.Turning round 13 thicker ends is the round steel cold-heading molding, and there is a screw centre, and turning round 13 thinner ends is that round steel directly processes, with a thicker end by being threaded, and there is an elongated slot centre, is fixed together by round pin 35, and it is thick to adapt to different doors to adjust the length of turning round 13.

When outdoor locking a door, buckle 2 rotates and cuts in the deep trouth of buckle seat 3 around buckle axle 1, outer tapered end 4 is promoted inwards, its outerplanar with buckle seat 3 is flushed, this moment, the external diameter of outer tapered end 4 was pressed arc notch 19 on the buckle 2 into, simultaneously block 9 moves down into the top of feather key 8 in spring 16 effects, blocks outer tapered end 4, like this buckle 2 together with door by locking.When outdoor unlatching, key 32 is inserted in the keyhole of lock core 31, stir counterclockwise, block 9 was driven by lock core 31 and left feather key 8 tops this moment, outer tapered end 4 promptly is compressed spring 6 and ejects, and the arc notch 19 on the buckle 2 withdraws from by outer tapered end breach 18, and door lock is opened.When if buckle 2 does not withdraw from, the guiding circular arc 34 on the buckle 2 links to each other with fairlead 33 on the buckle seat 3, plays windbreak function.Rotate handgrip 17 during from indoor locking, drive in the buckle 2 incision buckle seats 3 by buckle axle 1, at this moment, pulling is turned round and is driven 13 in the outer tapered end 4 indentation buckle seats 3 by turning round a pin 7, reaches the locking effect.From indoor unlatching door lock, can rotate counterclockwise 13 turning round, turn round a pin 7 and stir pivoted housing 5 this moment, makes block 9 leave feather key 8 tops, and outer tapered end 4 promptly is compressed spring 6 and ejects, and rotates handgrip 17 then, makes buckle 2 withdraw from buckle seat 3, and door lock is opened.From indoor unlatching, if outer tapered end 4 is obstructed, compression spring 6 can not fully eject outer tapered end 4, can outwards move extreme position to 13 to turning round, then, stir counterclockwise again, at this moment, turn round a pin 7 and drop in the pivoted housing breach 10 and stir, treat that baffle plate 9 breaks away from the top of feather keys 8 after, turn round pin 7 is withstood on the end face of pivoted housing breach 10 simultaneously, outer tapered end semi-finals row can be released.If it is indoor unmanned or a Room is multi-door or be used for gate, in order to prevent that other people from opening from the inboard, can will turn round in advance and advance 13 in the inner lock heads 12, treat that locking plate 11 is dropped into to turn round a breach 15, turn round and promptly be lockable 13, during unlatching, must inject in the keyhole of internal cylinder 30 with key 32 earlier, rotate counterclockwise, locking plate 11 is left turn round a breach 15, turn round and promptly ejected 13, then could not influence outdoor normal unlatching and locking in this case from indoor unlatching door lock by spring 14.The utility model can be told some class at aspects such as appearance and modeling, surfacing, specification intensity, adopts to be suitable for different occasions.
