Fig. 2 is the schematic diagram of the car door lock of compound building lift car；
Fig. 3 is the structural schematic diagram that car door lock removes shell in Fig. 2；
Fig. 4 is the structural schematic diagram of the locking bar retracted mode of car door lock；
Fig. 5 is that the locking bar of car door lock stretches out the structural schematic diagram of state.
Specific embodiment
The technical scheme of the invention is described in detail through specific implementation examples.
As shown in Fig. 1 to 5, compound building lift car includes car top 2, car floor 3, sedan-chair wall 4 and gate 5, and gate 5 is hinged on sedan-chair
On wall 4, car door lock 1 is equipped between car top 2 and gate 5, car door lock 1 is mounted at car top, and gate 5 is equipped with lockhole 50.
Car door lock 1 includes bottom plate 11 and shell 10, is equipped with driving mechanism, transmission mechanism and locking bar 12 on bottom plate 11.It drives
Motivation structure includes motor 13, screw rod 14, slider nut 15 and sliding rail, and sliding rail is located on bottom plate 11, and slider nut 15 is mounted on cunning
On rail, screw rod 14 is inserted into composition turn-screw pair of nut in slider nut 15.Transmission mechanism includes pushing away of being successively articulated and connected
Pull rod 16, connecting rod 17 and connecting lever 18, push-pull rod 16 are fixedly connected with slider nut 15, are set on connecting lever 18 there are two circular hole and one
A slotted hole is located in the middle on the support 111 that circular hole is used to be installed in rotation on connecting lever on bottom plate, another circular hole is used
Come with connecting rod 17 hingedly, be slotted hole with the junction of locking bar 12 on connecting lever 18, locking bar 12 is equipped with pin shaft, and pin shaft is oval
It can be relative to sliding and rotating, so that one end of locking bar 12 can slidably be hinged on one end of connecting lever 18 relatively in hole.Bottom
Nylon bush 19 is inlaid in plate 11, locking bar 12 is inserted in nylon bush 19, and the inner hole of nylon bush 19 is formed for 12 edge of locking bar
The mobile pilot hole of its length direction.In the present embodiment, motor uses stepper motor.
As shown in Figure 4,5, when the slider nut of stepper motor is located at the rightmost side, car door lock is in the open state, stepping electricity
Machine drive slider nut does the linear motion of horizontal direction toward left side, and push-pull rod is flat toward left side straight line together with slider nut
It moving, push-pull rod pushes connecting rod, and connecting rod is transmitted to thrust one end of connecting lever, make support rotation of the connecting lever on bottom plate,
Connecting lever passes through and the pin shaft of locking bar junction pushes locking bar to move down along the nylon bush being mounted on bottom plate, to realize
Locking bar stretching.The action process that car door lock is opened is opposite with the above movement.Due to using screw pair, have self-locking
Effect, so locking bar is in self-locking state after stretching out, it is possible to prevente effectively from preventing user from taking off door a possibility that locking bar involuntary maneuver
The accident for causing door lock to fail protects the personal safety of elevator ride personnel.In addition, motor can avoid starting using flexible drive
With impact when closing, extremely low mechanism operation noise may be implemented, especially suitable for the higher domestic environment of noise requirements,
Avoid influence of the noise to user.
In other embodiments, car door lock can also be mounted on gate, and by corresponding lockhole be provided with car top or
In car floor or sedan-chair wall.
In other embodiments, elongated slot or long hole can also be set in the end of locking bar, set on connecting lever it is corresponding protrusion or
Shaft, realize locking bar end and connecting lever end relative to sliding and rotate.
In the embodiment of elevator cage door lock of the invention with the knot of the car door lock in above-mentioned compound building lift car embodiment
Structure is identical, and it will not be described here.
