The latch bolt structure of the pushing/drawing-back type door lock of the utility model, has the advantages that
When toggle mechanism is stirred latch bolt component by connection component and is detached from from doorframe, pivot can be made sliding in sliding slot
It is dynamic so that spacing breach is separated with limited step, when promotion door lock handle is by door-lock opening, the side of latch bolt by thrust,
So that latch bolt toward lock body interior direction rotate so that latch bolt is exited from doorframe, reach and open door, and can smoothly by
Door is opened, and the friction with doorframe buckle of latch bolt is reduced, and is reduced abrasion, is improved service life.
Detailed description of the invention
Fig. 1 is the structure chart of the latch bolt structure of the utility model pushing/drawing-back type door lock；
Fig. 2 is the decomposition view of the latch bolt component of the latch bolt structure of the utility model pushing/drawing-back type door lock；
Fig. 3 is the topology view of connection component described in the latch bolt structure of the utility model pushing/drawing-back type door lock.
Specific embodiment
The following detailed description will be further explained with reference to the above drawings.
Hereinafter, a variety of specific details are elaborated, in order to provide to the saturating of the concept for constituting described embodiment basis
Thorough understanding.However, it will be apparent to those skilled in the art that described embodiment can be in these no specific details
In some or all situations get off practice.In other cases, well-known processing step is not specifically described.
As shown in Figure 1-3, the latch bolt structure of pushing/drawing-back type door lock, including the latch bolt component 1 locked in doorframe and by latch bolt group
The connection component 3 that part 1 is connect with toggle mechanism 2.The latch bolt component 1 include the pull rod 10 being connect with the connection component 3 and
With the latch bolt 11 of the pull rod 10 pivot joint connection.The pull rod 10 is equipped with sliding slot 100, the latch bolt 11 and 10 pivot of pull rod
The pivot 12 connect runs through the sliding slot 100.The pull rod 10 be equipped with limited step 101, the latch bolt 11 be equipped with it is described
The spacing breach 110 that limited step 101 cooperates；The connection component 3 pulls the pull rod 10 to move in lock body, the limit
Notch 110 is separated with the limited step 101, in the lateral forces of the latch bolt 11, the side in lock body of latch bolt 11
To rotation.When pushing door lock handle by door-lock opening, the side of latch bolt 11 is by thrust, so that the side in lock body of latch bolt 11
