Description
Technical field
The utility model belongs to lock technology field, relates to a kind of door lock, particularly a kind of handle-type door lock.
Background technology
Common door lock mainly is comprised of key operated part, lock body, cage knob and dead bolt etc., in the room, open the door that common door lock is housed, it all is the twisting cage knob, open and spur again cage knob behind the dead bolt and open the door, but the cage knob of most of door locks is all smaller, make during pulling not energetically, when door closes tightlyer, especially feel inconvenient.Thus, people have invented a kind of handle-type door lock, and the handle of this handle-type door lock is larger, and are more laborsaving during operation.But this door lock is installed inconvenient, even dead bolt is packed into behind the lock body, owing to lack the fixed structure of dead bolt, dead bolt still very easily comes off in lock body, causes door lock to lose efficacy.At closing time, pull handle, the inner of handle promotes dead bolt, make it inner mobile to lock body, owing to have the gap between lock body and the dead bolt, when dead bolt moves to lock body is inner, because guide frame is not set, only depend on the inside wall guiding of lock body, the position of dead bolt is offset easily, and after being offset, dead bolt is stuck in lock body easily, dead bolt can not reset, and application life is short.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of handle-type door lock easy for installation, well-set.
The purpose of this utility model can realize by following technical proposal:
This handle-type door lock, comprise lock body and be located at the interior dead bolt of this lock body, described lock body is provided with Connection Block, be hinged with handle on the described Connection Block, the outer end of described handle is free end, the inner of described handle is passed lock body and is inserted in the slot of dead bolt, be provided with elastic reset spare between the inner of described dead bolt and the lock body, it is characterized in that, the inner end of described dead bolt is provided with pilot hole, described pilot hole extends along the direction of motion of dead bolt, described lock body is provided with an end and is inserted into the interior guide peg of this pilot hole, above-mentioned elastic reset spare is set on this guide peg, and also is provided be used to the disconnecting prevention structure that prevents that dead bolt from coming off between described dead bolt and the lock body.
When locking a door, dead bolt pushes with the lock box that is fixed on the doorframe, because the end face of dead bolt is vamp, dead bolt is inner mobile to lock body, and the compressive strain of elastic reset spare is after the complete closure of door, elastic reset spare resets, it is outwards mobile to promote dead bolt, and dead bolt is inserted in the lock box on the doorframe, and door is locked.When opening the door, pull handle, the inner extruding dead bolt of handle makes dead bolt inner mobile to lock body, and when pulling handle, opposite house applies an outside power, and after dead bolt broke away from lock box, door was opened.This door lock operation is simple, and is easy for installation, and sound construction is reliable.
In above-mentioned handle-type door lock, described disconnecting prevention structure comprises the elastic baffle of being located on the lock body inside wall and the stop part of being located on the dead bolt sidewall, the setting that slopes inwardly of described elastic baffle, when door lock was closed, described stop part had been resisted against on the described elastic baffle under the effect of above-mentioned elastic reset spare elastic force.
In above-mentioned handle-type door lock, described stop part is tabular and outward-dipping setting, when door lock is closed, is resisted against in the inclination inboard of described stop part under the effect of elastic reset spare elastic force on the inclination inboard of described elastic baffle.
In above-mentioned handle-type door lock, described stop part is made by elastomeric material.
In above-mentioned handle-type door lock, described elastic reset spare is spring.
In above-mentioned handle-type door lock, an end of described spring is resisted against on the lock body, and the other end of this spring is resisted against the bottom of pilot hole.
Compared with prior art, this handle-type door lock has the following advantages:
Mounting handle on lock body, the pulling handle can be opened dead bolt and door simultaneously, and is easy to operate, time saving and energy saving; And be provided with guide frame in the inner of dead bolt, and prevent that dead bolt is offset, guaranteed the operating accuracy of door lock, prolonged the application life of door lock; Moreover, between dead bolt and lock body, being provided with disconnecting prevention structure, this structure can prevent effectively that dead bolt from coming off.
