The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Extremely shown in Figure 11 like Fig. 1; Car door lock in a kind of door lock of elevator; Comprise main bottom-locking plate 6, laterally be provided with two parallel sliding bars 7 on the main bottom-locking plate 6, on two parallel sliding bars 7, be provided with the latch hook body device that can be free to slide, be provided with the switching device that cooperates the latch hook body device to close work and carry out electric affirmation, and be installed in gate lock that layer door go up bank and cooperate the latch hook body device to open work and open and hit bow 15 in latch hook body device one side; The latch hook body device comprise through nylon jacket 5 be serially connected in latch hook adapter plate 10 on the sliding bar 7, be provided with above the latch hook adapter plate 10 latch hook 11 that is rotationally connected with latch hook adapter plate 10, above latch hook 11, be provided with bump wheel 12, be provided with at latch hook adapter plate 10 1 ends and hook latch hook adapter plate 10, the other end hooks first retracing spring 2 of main bottom-locking plate 6; Be connected with second retracing spring, 3, the second retracing springs, 3 other ends of assisting latch hook 11 self gravitations that latch hook 11 and switching device are closed on the latch hook 11 and hook latch hook adapter plate 10.Latch hook 11 adopts bearings to be rotationally connected with latch hook adapter plate 10, and latch hook adapter plate 10 belows are provided with guarantees that latch hook 11 is at put in place the spacing glue 4 of restriction of the effect down stroke of self gravitation and second retracing spring, 3 auxiliary forces; Switching device is included in latch hook adapter plate 10 1 sides and is provided with the switch adapter plate 9 that carries out electric affirmation, switch 8 that switch adapter plate 9 is provided with, is provided with contact 13, is provided with the top glue 1 that matches and promote with extension rod at corresponding latch hook adapter plate 10 midways location of extension rod with contact adapter plate 14, contact adapter plate 14 that latch hook 11 corresponding positions are provided with the band extension rod.
Extremely shown in Figure 6 like Fig. 1; Latch hook 11 is fixed on the latch hook adapter plate 10 through riveting bearing mode; The latch hook body device is serially connected on two parallel sliding bars 7 and makes up with main bottom-locking plate 6; First retracing spring, 2 two are hooked in respectively on latch hook adapter plate 10 and the main bottom-locking plate 6, and the stressed flexible latch hook body device through first retracing spring 2 is free to slide on two parallel sliding bars 7, and the latch hook body device connects latch hooks 11 through switch adapter plate 9 switches 8 are installed; Second retracing spring 3 is auxiliary latch hook 11 gravity, cooperates spacing glue 4 to guarantee that latch hook 11 and switch 8 are closed under the effect of latch hook 11 self gravitations and second retracing spring, 3 auxiliary forces and puts in place.After the latch hook body device is fixed on the main bottom-locking plate 6; Be installed on the base plate of door opening machine for elevator; Be in static relatively location status with the door opener base plate, be in the relative motion state, after contact 13 is fixed on the contact adapter plate 14 with the door opener link plate; Be installed on the door machine link plate of switch 8 relative sides, both realize the requirement that the sound of this door lock requirement cooperates.
Extremely shown in Figure 10 like Fig. 7, when elevator door-motor is in the flat bed zone, in the process of closing the door; The extension rod of contact adapter plate 14 partly promotes the latch hook body device and on sliding bar 7, moves, in the process that moves, when the bumping wheel 12 on the latch hook 11 breaks away from and is installed in layer door and goes up the gate lock of bank and open when hitting the stopping of bow 15; The contact 13 that is installed on the contact adapter plate 14 begins to keep connecting with the switch 8 that is installed on the switch adapter plate 9; Latch hook 11 makes switch and contact cut out door-closing in-place through the auxiliary force of the self gravitation and second retracing spring 3; Bumping wheel 12 and gate lock on the latch hook 11 are opened and are hit bow 15 and keep the 5-8mm distances; Until opening the door again, during elevator door-motor upstream and downstream process, the centre runs into the stop of not stopping; Bump wheel 12 and gate lock and open and hit bow 15 and can not wipe all the time and bump, realized operation noiselessness, the synchronous effect of door lock folding; When the door machine is in the flat bed zone; The process of opening the door; Door machine driving band drives link plate and door-plate moves to the direction of opening the door, and the latch hook body device receives the effect of first retracing spring, 2 pulling force, and the bumping wheel 12 when on sliding bar 7, sliding about 5-8mm on the latch hook 11 receives the gate lock that is installed in bank on the layer door and opens to hit and bend 15 stop and can not continue to move; The fitted bearing of the switch 8 that forces latch hook 11 and be connected with latch hook on latch hook adapter plate 10 rotates and opens, and accomplishes the process of opening the door.
When the door machine was in uneven layer state, bumping on the above-mentioned process of the opening the door latch hook 11 takes turns 12 can not receive the application force that bow 15 is hit in the unlatching of gate lock, and the gate lock can not be opened; Continue pulling and open the door, on sliding bar 7, can the slide distance of about 25mm of latch hook body device, the slit of two door-plates can reach the gap of about 50mm; Guarantee that the door machine is when non-flat bed failover stops; The primary safety that guarantees personnel in the car, personnel can not open the car door of non-flat bed without authorization in the car, prevent to fall into the danger of hoistway; Simultaneously two door-plates can be pushed the gap of reaching 50mm, prevent that the car internal cause from failing for a long time to solve when requiring assistance problem that personnel cause damage because of anoxic in the car.
Above-described only is the preferred implementation of the car door lock in a kind of door lock of elevator of the utility model; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
