Abstract
The utility model discloses a kind of labella linkage structures of mortise lock body, including lock body, the labella being connect with labella pulling plate being located on lock body, the main tongue pulling plate being connect with main tongue, the universe rod with the linkage of main tongue pulling plate；The labella pulling plate is connect by the labella driver blade being hinged on lock body with the universe rod；The labella driver blade is matched with the transmission pin on the transmission pin and labella pulling plate on the universe rod respectively by being located at inclined hole slot thereon and V-shaped groove or arc groove, realizes the linkage of the labella and the universe rod.The utility model is in locking, due to the V-shaped groove on labella driver blade（Or arc groove）A part and labella substantially close to 90 degree, certain position-limiting action can be played to labella in the labella direction of motion so that labella is not easy in outer force effect retraction lock body, to which its safety can be improved.
Description
Technical field
The utility model belongs to lockset, and in particular to a kind of labella linkage structure of mortise lock body.
Background technology
The mortise lock body for door on the market include lock core, main tongue, labella, universe rod and lock core with main tongue, labella,
The linkage structure of universe rod connection can drive main tongue, labella movement to realize and unlock and be latched by lock core by linkage structure.It is existing
Mortise lock body when in use, due to drive mechanism design it is unreasonable so that labella is easy retraction lock body under external force, exists
Security risk.
Invention content
The purpose of this utility model is to provide a kind of reasonable for structure, labella linkage structure of the good mortise lock body of safety.
Realizing the technical solution of the utility model aim is：
The labella linkage structure of mortise lock body provided by the utility model, including lock body, be located on lock body with labella draw
The labella of plate connection, the main tongue pulling plate being connect with main tongue, the universe rod with the linkage of main tongue pulling plate；The labella pulling plate passes through hinged
Labella driver blade on lock body is connect with the universe rod；The labella driver blade is by being located at inclined hole slot and V-arrangement thereon
Slot or arc groove are matched with the transmission pin on the transmission pin and labella pulling plate on the universe rod respectively, realize the pair
The linkage of tongue and the universe rod.
Advantageous effect：
The utility model locking when, due to the V-shaped groove on labella driver blade（Or arc groove）A part and labella
Substantially close to 90 degree, certain position-limiting action can be played to labella in the labella direction of motion so that labella is not easy in outer masterpiece
With in retraction lock body, to which its safety can be improved.
The utility model is described further below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the use state diagram of the utility model.
Specific implementation mode
See Fig. 1, the labella linkage structure of mortise lock body provided by the utility model, including shell 6 and passes through liner plate holder 3
The vertical liner plate 1 for being located at 6 side of shell, shell 6 is interior to be equipped with main tongue 7, labella 4, universe rod 2, and main tongue 7, labella 4 are stretched from liner plate 1
Going out can match with the lockhole on side door frame, universe rod 2 from the both ends of shell 6 stretch out can be up and down on doorframe lockhole match,
Main tongue 7 is fixedly connected with main tongue pulling plate 10, and main tongue pulling plate 10 passes through universe rod driving nail 8 and 201 phase of inclined hole slot on universe rod 2
Cooperation；The labella 4 is fixedly connected with labella pulling plate 5, the pin that labella pulling plate 5 is equipped with guide groove 502 and is located on shell 6
601 match, and labella pulling plate 5 is connect by the labella driver blade 9 being hinged on shell 6 with the universe rod 2, and wherein labella passes
Movable plate 9 is hinged on pin 601, and labella driver blade 9 is equipped with inclined hole slot 901 and V-shaped groove（Or arc groove）902 respectively with the world
The transmission pin 501 on transmission pin 202 and labella pulling plate 5 on bar 2 matches, and labella 4 and labella pulling plate 5 are passed by labella
Movable plate 9 connect the linkage realized with universe rod 2 with universe rod 2.
When locking, as shown in Figure 1, rotation lock core（It does not draw）Drive the main movement of tongue pulling plate 10 that main tongue 7 is made to stretch out lock body, main tongue
Pulling plate 10 drives universe rod 2 to stretch out lock body simultaneously, and universe rod 2 drives 5 movement of labella pulling plate to make labella further through labella driver blade 9
4 stretch out lock body, and unlocking process is with locking on the contrary, as shown in Figure 2.
Since labella driver blade 9 is in locking, V-shaped groove thereon（Or arc groove）902 part connects substantially with labella 4
Nearly 90 degree, certain position-limiting action can be played to labella 4 in 4 direction of motion of labella so that labella 4 is not easy to contract in outer force effect
It returns in lock body, to improve its safety.
