Abstract
The utility model discloses a sliding door lock which comprises a lock body. A lock dog is arranged inside the lock body, one end of the lock dog can protrude from the lock body and the other end of the lock dog is connected with the inside of the lock body in a rotating mode. A pin is further fixedly arranged on the lock dog. The lock body further comprises a transmission piece. The middle of the transmission piece is connected with the lock body through a pivot in a rotating mode. One side of the pivot is a stirring part which protrudes from the lock body and the protruding direction is different from that of the lock dog. The other side of the pivot is a transmission part which is provided with a pin hole and the pin hole matches with the pin of the lock dog. The lock body of the sliding door lock is simple and stable in structure, smooth to open and small and exquisite in appearance and can be applied to a thin sliding door lock. Meanwhile, the lock dog performs the functions of anti-prying and anti-stirring and therefore an anti-theft function is enhanced.
Description
Technical field
The utility model relates to field of lockset, relates in particular to a kind of sliding door lock.
Background technology
Along with urbanization process, in order to practice thrift more space, the application of sliding door lock more and more widely during the family interior decoration.Correspondingly, on the market sliding door lock is also more and more.But present sliding door lock theftproof is relatively poor; When lock body colludes tongue and stretches out; There is not backwash to prevent that promptly lock body is through colluding the function that tongue portion is opened; Therefore other people can get into the house theft with door-lock opening with things such as steel wires outdoors easily, and such sliding door lock does not reach anti-theft effect, can bring loss economically to the user.People press for the better sliding door lock of anti-theft effect.
Summary of the invention
The utility model aims to provide a kind of sliding door lock, has the backwash function, can prevent to unblank with things such as steel wires from the outside.
For this reason, the technical scheme that the utility model adopted is such: be provided with in the lock body and collude tongue, collude tongue one end and can stretch out in outside the lock body, the other end is rotationally connected with in the lock body, colludes a pin also fixedly is housed on the tongue; Lock body also comprises driver blade, and the driver blade middle part is rotationally connected through fulcrum and lock body, and a side of fulcrum is the clicking section; Stretch out outside the lock body clicking section, and with to collude the direction that tongue stretches out different, the opposite side of fulcrum is the driving section; The driving section has pin-and-hole, and pin-and-hole cooperates with the pin that colludes tongue.
As the further technical scheme of the utility model: the moment that the moment that the gravity of clicking section is produced for the driver blade fulcrum is produced for the driver blade fulcrum greater than the gravity of driving section.
Because the moment that the moment that the gravity of clicking section is produced for the driver blade fulcrum is produced for the driver blade fulcrum greater than the gravity of driving section; The torque around fulcrum that comprehensive clicking section and the driving section of driver blade produced makes the trend that the tongue generation is stretched out of colluding all the time through pin; Lock body is when pinning door; Collude tongue and stretch out, driver blade is in low level, if when colluding tongue and up dialled by the external force effect this moment; Driver blade makes and colludes the trend of stretching out that tongue produces and can produce inhibition to this it can't be dialled back, thus realization dead bolt backwash function.
Personnel only need upwards stir driver blade through the external part of driver blade if need open door lock in the door at this moment, and driver blade makes through the pin transmission and colludes in the tongue income lock body, can realize unblanking; Can do the operation of contrary in the time of need locking a door once more, stir downwards and wear moving plate and realize locking a door.
The lock body structure that the utility model provides is simply firm, opens more smooth and easyly, and the profile exquisiteness is small and exquisite, can be suitable for the thin type sliding door lock, and dead bolt possesses pick-proof, the anti-function of dialling, and strengthens theftproof performance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model locking states sketch map.
Fig. 2 is the utility model opening sketch map.
The specific embodiment
Referring to accompanying drawing, have tongue of colluding 2 and driver blade 3 in the lock body 1.Collude tongue 2 one end 2a and be rotationally connected with in the lock body 1, and pin 4 is housed, other end 2b can stretch out or takes in lock body because of the rotation of colluding tongue 2.Driver blade 3 middle parts are rotationally connected with in the lock body 1 through fulcrum 8, and fulcrum 8 one sides are clicking section 5, stretch out outside the lock body 1, are used to receive external force that driver blade 3 is rotated, and fulcrum 8 opposite sides are driving section 6, and driving section 6 has pin-and-hole 7, and pin-and-hole 7 cooperates with pin 4.The gravity of clicking section 5 and driving section 6 all produces moment for fulcrum 8; But the two is in the opposite direction; It is bigger that the gravity of clicking section 5 produces moments for fulcrum 8, so driver blade 3 self has a clockwise torque all the time, and this torque makes colludes tongue 2 and have the trend of stretching out all the time.
During lock body 1 locking; Collude tongue 2 and stretch out, have if outside thing such as steel wire to apply power upwards at this moment and open door lock, make and collude tongue 2 and produce the trend of taking in the other end 2b place desire of colluding tongue 2; And driver blade 3 can hinder the trend of stretching out of colluding tongue 2 generations to the trend of income, thereby realizes the antitheft effect.
Under the normal condition, personnel need open and close door lock time the in the door, as long as the clicking section 5 of stirring driver blade 3 up and down, the transmission through power makes colludes tongue 2 incomes or stretches out lock body 1, can realize opening and closing.
