Fig. 3 is the structural representation of the latch hook of the utility model when breaking away from snap close.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

Extremely shown in Figure 3 like Fig. 1, the described elevator cage door lock synchronous door knife of the utility model, its structure is that it comprises a tool arm 1, door tool arm 22, door tool arm 36, driving gate cutter mount pad 3, driven door cutter mount pad 8, swing arm 20 and latch hook 4; Said door tool arm 1, door tool arm 22, door tool arm 36 are arranged in parallel, and said door tool arm 22 is arranged between a tool arm 1 and the door tool arm 36; The left end of said driving gate cutter mount pad 3 is articulated in the top of said door tool arm 1; The right-hand member of driving gate cutter mount pad 3 is articulated in the top of said door tool arm 36; The left end of said driven door cutter mount pad 8 is articulated in the middle and lower part of said door tool arm 1; The right-hand member of driven door cutter mount pad 8 is articulated in the middle and lower part of said door tool arm 36, and said door tool arm 1, door tool arm 36, driving gate cutter mount pad 3 and driven door cutter mount pad 8 form four-bar linkage; The left end of said latch hook 4 is articulated in the middle and upper part of said door tool arm 22; The middle part of latch hook 4 is articulated in the middle and upper part of said door tool arm 36; The left end of said swing arm 20 is articulated in the bottom of said door tool arm 22, and the right-hand member of swing arm 20 is articulated in the bottom of said door tool arm 36; Said door tool arm 22, door tool arm 36, latch hook 4 and swing arm 20 form four-bar linkage; The right-hand member of said latch hook 4 is provided with the clasp that the snap close 19 with gate door machine bottom board is complementary.

Further, the bottom of said door tool arm 22 is provided with the support 11 of unblanking, and conveniently stirs the support 11 of unblanking by other instruments, forces a tool arm 2 22 rotations, thereby opens gate.Further, the upper and lower of said door tool arm 36 is provided with rubber block 9, has both played to prevent that a tool arm 36 and the door tool arm 22 from colliding and damage, and takes spacing and the effect that reduces noise again to.Further, said driving gate cutter mount pad 3 is provided with back-up ring 7 with driven door cutter mount pad 8, and back-up ring 7 is arranged at the relevant position of jointed shaft, and the effect of back-up ring 7 is after axle and bearing installation are intact, prevents that axle from separating with bearing.

The said elevator cage door lock synchronous door knife of the utility model, its principle of work is:

When gate is opened; The door machine drives driving gate cutter mount pad 3 left-hand revolutions synchronously, and at first tool arm 1 shrinks with door tool arm 36, drives door tool arm 22 simultaneously and shrinks; Door tool arm 1 and door tool arm 22 interior folder Room every balls; Croquet is opened Room every lock, and door tool arm 1 forms interlock with door tool arm 36 and driving gate cutter mount pad 3, driven door cutter mount pad 8 simultaneously, and the latch hook 4 of gate lock breaks away from snap close 19; Electrical contact and touch base break off simultaneously, and door tool arm 1 opens the door with door tool arm 22 drive Room every balls synchronously.

When the door machine at closing time, close the door on earth before, door tool arm 1 still remains retracted with a door tool arm 36, a door tool arm 22; Be in engagement with Room door, behind the door-closing in-place, the door cutter is when door-closing in-place; Door tool arm 1, door tool arm 36, door tool arm 22 open the engagement of withdrawing from Room door; The latch hook 4 of gate lock meshes with snap close 19 under gravity and extension spring effect simultaneously, through interlock mechanism gate is locked the closed conducting of gate lock contact and touch base simultaneously.

When door machine during at non-flat stratification; The latch hook 4 of gate lock pins with snap close 19; Can't open gate; Can effectively prevent to be opened gate at the non-level position of elevator by personnel in the car, or in the up-and-down movement process or other disturb enabling signal maloperations and open gate, thereby the personnel in the car of stopping take off the fall potential safety hazard of hoistway of door when non-level position.

When door machine during at level position, if the people takes off door in car, a door cutter will move with door-plate; When Room every ball knocked a tool arm 22, it moved downward in the four-bar linkage that forms with swing arm 20, door tool arm 36, at first forces the latch hook 4 of gate lock to break away from snap closes 19; When continuing again to take off; Room every ball rotation is opened Room every lock, and personnel can save oneself in the stranded car.

When door machine during, in outage in emergency circumstances, can open Room door lock through triangular key at level position; Push the about 40mm of Room door aside, see through the support 11 of unblanking that crack between a door and its frame can be seen a cutter this moment, stirs the support 11 of unblanking by other instruments; Force a tool arm 22 rotations; The latch hook 4 of gate lock breaks away from snap close 19, and electrical contact and touch base break off simultaneously, and gate is pushed aside.

In sum; The said elevator cage door lock synchronous door knife of the utility model; With the design of door cutter and door lock integral type, be applicable to elevator normal switch door, level position is saved oneself or the situation such as open the door, non-level position prevents to open the door of cutting off the power supply, and has simple in structure; Convenient for installation and maintenance, can stop the advantage of potential safety hazard.

The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
