Abstract
An elevator cage door lock includes body, lock groove disposed on the body, and lock-tongue disposed in the lock groove. When the cage door lock is at lock status, the lock-tongue protrudes to the outside from the body, when the cage door lock is at unlocking status, the lock-tongue retracts into the body. The lock-tongue is connected with a position control mechanism which can control the movement for the lock-tongue and control the cage door lock to lock status when the cage is running to prevent the cage door from being opened during the running process, thereby the safety of the elevator is improved.
Description
Technical field
The utility model relates to a kind of car door lock of elevator, is used to lock the doorframe of car door and car.
Background technology
In the prior art, because common no door lock between the car door of elevator and the doorframe of car, when the cage operation of elevator is distinguished to opening the door, car door is opened automatically, and car door is closed the back car and can be moved, but when elevator breaks down, car door is easily owing to respond to mistake and opens, and if car door when opening the car off-duty then can cause Peril Incident to opening the door the district.
Summary of the invention
The utility model purpose provides a kind of car door lock of elevator, can be when cage operation the doorframe of car door and car be pinned.
For achieving the above object, the technical solution adopted in the utility model is: a kind of car door lock of elevator, it comprises body, be opened in locked groove on the described body, be arranged at the dead bolt in the described locked groove, when described car door lock is in the lock state, described dead bolt stretches out outside the body, when described car door lock was in released state, described dead bolt took in the body, was connected with position control mechanism on the described dead bolt.
Because technique scheme utilization, the utility model compared with prior art has following advantage: move the position of operating position control mechanism may command dead bolt, can control this car door lock in cage operation is in the lock state, so that car door and doorframe are pinned, and be in when district of opening the door when car, move so that the car door-lock opening by position control mechanism control dead bolt, it is simple in structure, can prevent that car door accident in the cage operation process from opening, thus the safety that can improve elevator.

The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 4, a kind of car door lock of elevator, it comprises body 8, be opened in locked groove 11 on the described body 8, be arranged at the dead bolt 9 in the described locked groove 11, is provided with spring 7 between described dead bolt 9 and the body 8.When described car door lock was in the lock state, described dead bolt stretched out outside the body 8, and when described car door lock was in released state, described dead bolt took in the body 8.
Be connected with position control mechanism on the described dead bolt 9, described position control mechanism comprises with described body 8 phase pivot bonded assembly first connecting rods 5, is connected the second connecting rod 6 of an end of described first connecting rod 5, and the other end of described first connecting rod 5 is connected with dead bolt 9.
Described car door lock comprises also and body 8 relatively-stationary bearings 1 that be rotatably connected to handler 10 on the described bearing 1, described handler 10 rotates with described second connecting rod 6 and is connected.Be fixedly connected with croquet handle 2 on the described handler 10, described croquet handle 2 is provided with croquet 3.
The utility model is installed on the doorframe column of car when using, if the car door of elevator is a left hand model, the utility model is installed on the doorframe right column, and if the car door of elevator is a right hand model, then the utility model is installed on the doorframe left column.When the car of elevator not when stopping the district because the elastic force effect of spring 7 makes that dead bolt 9 is ejected outside the bodies 8, thereby dead bolt 9 pins (referring to accompanying drawing 3-accompanying drawing 4) with car door and doorframe; When the cage operation of elevator to the district of opening the door when (district promptly stops), hitting bow 4 on the car is depressed croquet 3, croquet handle 2 promptly drives handler 10 and rotates relative to bearing 1, make second connecting rod 6 move by lever principle, thereby driving first connecting rod 5 relative bodies 8 sways, and drive tension force that dead bolt 9 overcomes spring 7 by lever principle and move and take in the body 8, make car door can open (referring to accompanying drawing 1-accompanying drawing 2).Referring to accompanying drawing 5, the utlity model has door lock contact 12, have door-plate contact 13 on the door-plate of car, when car is not stopping when district, door lock contact 12 contacts with door-plate contact 13, make the car of elevator to move up and down, and if car door is not shut, promptly door lock contact 12 is not closed with door-plate contact 13, makes the control power supply dead electricity of elevator, elevator then can't work on, and can prevent elevator cage operation when car door unlatching personnel enter hoistway and causes the accident.Triangulation chain 14 also is installed on the utility model, makes when elevator breaks down, the maintainer can open triangulation chain and enter hoistway and carry out maintenance operation.
