Abstract

The utility model relates to a door lock without an oblique bolt. The oblique bolt of the original door lock is changed into a square bolt. An oblong clamping plate is fixed on the inlet and outlet end face of the square bolt and a lock body by using rivets (or screws), wherein, the middle of the oblong clamping plate is provided with an opening, and the upper and the lower edges of the oblong clamping plate are provided with long waist circular holes. The square bolt forms a sliding connection with the lock body. The inner end of the clamping plate butted the door is pressed by a spring piece arranged on the lock body. Generally, the square bolt is clamped in the lock body by the clamping plate. At the time of door closing, the outer end of the clamping plate is contacted with a buffer block on a door frame to realize automatic door locking. The utility model has the advantages of simple structure, convenient installation and processing, low cost, good anti-theft performance, metal material saving and novel design, and is suitable for all door locks.

Description

There is not oblique flapper lock

The utility model relates to a kind of building door lock.

Have door that lock is just arranged, door lock has important role in people's daily life.Locking a door automatically of door locks such as existing single tongue, two tongue, sphere, lock pin all is to rely on a dead bolt collision keeper that has the inclined-plane to finish.Be to strengthen theftproof performance, the door lock that has increases one or more square (or garden shape) dead bolt again in addition, but these dead bolts all must wait to close behind the door to finish the state that opens or closes with key, uses very inconvenience, and for example two flappers locks come to this.

Existing oblique flapper has latched following weak point: poor safety performance (just can open door with resident identification card); Tiltedly tongue collides for a long time, can form groove on the inclined-plane, and giving closes the door brings noise and vibrations, uses extremely inconvenient; For strengthening the two tongues or the multi-bolt door lock of theftproof performance, volume is big, quality is heavy, cost is high, the waste metal material, and is pretty troublesome when locking a door.

The purpose of this utility model is a kind of side's flapper lock of design, also can reach the effect of locking a door automatically, to overcome above-mentioned deficiency.

The purpose of this utility model can be by following scheme implementation: this lock changes the inclined-plane dead bolt in the square tongue of slope-less, the in-out end of dead bolt is provided with movable clamp, be processed with four shape holes, long waist garden on this clamp and through stairstepping pin riveted on lock body, formation is slidingly matched; The exceed position of fabrication plate, the front of lock body is provided with spring leaf, and this spring leaf is pushed down an end of clamp, and at closing time, the other end of clamp contacts with buffer stopper on being contained in doorframe.

No oblique flapper lock of the present utility model, simple in structure, installation and processing is convenient, and with low cost, theftproof performance is good, saves a large amount of metal material, and modern design is applicable to all door locks, and utmost point market is widely arranged.

The utility model is provided by following examples and accompanying drawing:

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view (having left out buffer stopper [3] and keeper [4]) of Fig. 1

Fig. 3 is the right view (having left out lock body [1]) of Fig. 1

Describe the details and the mode of occupation of the no oblique flapper lock that the utility model proposes in detail below in conjunction with Fig. 1-3.

The big slightly hole of the intermediate open position of the clamp that one block length is square [2] analogy tongue [5], and on the both sides of clamp along the thickness direction processing shape hole, four long waist gardens of door, with the stairstepping rivet clamp is fixed on lock body [1] end face, make it to constitute and be slidingly connected, tightly being pushed down by spring leaf [6] of clamp by the door inner end, spring leaf is screwed on lock body; Leaning on outdoors of clamp held at closing time, joins with the buffer stopper [3] that is contained on the doorframe, and when the Kong Yufang of clamp tongue alignd, square tongue was just realized locking a door automatically toward the motion of keeper [4] lining.

Usually, clamp is subjected to the pressure of spring leaf, and clamp is on the outermost extreme position, and clamp blocks square tongue in lock body and (exposed outside the lock body as square tongue, needed only square tongue inward by advancing).At this moment close the door, when the outer end for the treatment of clamp contacted with buffer stopper, clamp overcame the pressure of spring leaf and slides in door, and when the Kong Yufang of clamp tongue alignd, square tongue just moved in keeper, reached the purpose of locking a door.When opening the door, because the active force of key draws in square tongue in the lock body, clamp slides into extreme position again outward under the pressure effect of spring leaf, again square tongue is stuck in the lock body.

The distance that clamp slides is regulated with increase and decrease buffer stopper thickness.

Claims (1)
