Utility model content
Utility model object: for problems of the prior art, the utility model provides a kind of push and pull bar to lock, and internal structure design is comparatively simple, low production cost, and it is more laborsaving to unblank and lock, and degree of safety is high, promotes Consumer's Experience.
Technical scheme: the utility model provides a kind of push and pull bar lock, comprise housing, lever bracket, pushing slide block, driving lever, dead bolt and bolt outer casing, wherein, the head of lever bracket is connected with the pole rear end thereof of enclosure interior, pushing slide block is enclosed within the front end of pole, rear end and the pole front end of driving lever are rotationally connected, there is the step-like of the first spring pushing slide block front portion for overlapping, the front end of driving lever is passed and effectively contacts with the afterbody of dead bolt in the first spring eye, dead bolt outer cover has step-like bolt outer casing, also overlap between the step and the head periphery of dead bolt of bolt outer casing and have the 3rd spring.
Further, also have the holder of central aperture in pole front end, be also provided with the second spring between the perforate sidewall of holder and driving lever, one end of the second spring effectively contacts with driving lever, and the other end effectively contacts with the sidewall of perforate.Driving lever can more effectively pop into position by the existence of the second spring.
Preferably, described driving lever also has boss, one end of the second spring is enclosed within boss and forms effective contact with driving lever.In order to make the second spring can form fixing effectively to contact with driving lever, driving lever arranging boss, the second spring housing is not easy to come off on this boss, ensureing the stable of the utility model performance.
Preferably, the stepped locations inwall of bolt outer casing is also provided with catch, the 3rd spring can be limited between dead bolt head and catch by this catch.The position of 3rd spring in dead bolt and dead bolt housing can be fixed by the setting of catch, optimizes the utility model performance.
Further, the utility model also comprises handle, and this handle is connected with housing into rotation, and the afterbody of lever bracket is positioned at this handle inside.Handle be arranged so that user more cosily can manipulate lever bracket.
Preferably, one end of described handle is formed by two the first latches and housing both sides and is rotationally connected.Normally handle is formed by two screws and housing in prior art and be rotationally connected, when handle screw after rotating for a long time easily occurs stripped thread, and by two the first latches handle and housing formed in the utility model and be rotationally connected, there will not be stripped thread phenomenon.
Preferably, the head of described lever bracket is rotationally connected by one end of the second latch and pole, and the second latch is through pole, and its two ends are fixedly connected with housing both sides respectively; By the second latch, lever bracket is fixed in pole and housing, makes the second snibbing position firm.
Further, described second latch is all parallel with two the first latches, the position of two the first latches is fixed respectively by two the 4th springs, wherein one end of two the 4th springs is each passed through two the first latches, the second latch that intermediate elastic portion is enclosed within pole both sides is respectively peripheral, and the other end is separately fixed on pole.In present embodiment, the position of the first latch is combined by the 4th spring and the second latch parallel with the first snibbing position and reach fixed effect, so, even if handle still can not change through the position of rotating the first latch for a long time, avoid frequent swing handle that the first latch is rocked place's pin hole, cause handle to come off.
Preferably, described first spring is big spring, and the second spring is little spring, and the 3rd spring is pagoda spring.The utility model selects dissimilar spring according to spring position and role, can make the effect of unblanking and lock that the utility model reaches optimum.
Operating principle and beneficial effect: when user's promotion or pull lever frame, lever bracket is around to rotate with the tie point of pole, pass through lever principle, the rear end of the head promotion pushing slide block of lever bracket causes it to compress the first spring along pole forward slip, the reach of pushing slide block drives driving lever to tilt to the right, the inclination of driving lever drives dead bolt to bolt outer casing internal contraction compression the 3rd spring, and this is the mode of unblanking; When unclamping handle, first spring launches to pop into position counter for pushing slide block, handle playbacks, driving lever backwash is returned original position due to elastic force effect when the first spring launches by the lower end of driving lever, driving lever playbacks, after dead bolt loses the pulling function of driving lever, the 3rd spring launches outside for dead bolt bolt outer casing openend of rebounding out, and dead bolt playbacks, and this is locking state.When using the utility model as seen by the above-mentioned course of work, user only needs to push away or tie-bar bridge by door-lock opening or can be locked, easy to operate, and internal construction is fairly simple, not fragile, safe and reliable, with low cost.
