As preferably, described car door lock also comprises retracing spring, being set in parallel on described lock pedestal of described retracing spring, and connects described gravity drop hammer and described lock pedestal along the length direction of described gravity drop hammer.Described retracing spring increases the restoring force of described car door lock, prevents described car door lock from surprisingly being opened.
As preferably, below described right tool arm and the hinged position of described hammerlock, hammerlock draw-in groove is set.Described hammerlock is stuck in described hammerlock draw-in groove, increases the area of contact between described right tool arm and described hammerlock, strengthens Joint strenght.
As preferably, described gravity drop hammer is vertical with described hammerlock.Make the coupling mechanism force of described car door lock when locking state in the vertical direction, with described latch hook and corresponding locked groove to lock direction identical, locking effect is best.
Disclosed in the utility model, a kind of elevator door knife has following beneficial effect: described door cutter and described car door lock are all arranged on described door cutter base plate, ensures described gate and layer door synchronization action, prevents gate from surprisingly opening.Described gravity drop hammer and the direction of described retracing spring to the power that described hammerlock applies are vertically downward, the locked groove corresponding with described latch hook and its to lock direction identical, locking effect improves greatly.The mode that described hammerlock draw-in groove makes described right tool arm and described hammerlock adopt face to contact carries out power transmission, reduces the stressed of hinged place, increases anchoring strength.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of elevator door knife.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.As shown in Figure 1, a kind of elevator door knife, it is characterized in that: comprise the door cutter base plate 1 be located on a machine, be arranged on the car door lock 11 on a cutter base plate 1, tool arm drive spindle 12, tool arm connecting rod 13, be set in parallel in left tool arm 14, right tool arm 15 on a cutter base plate 1 by tool arm drive spindle 12 and tool arm connecting rod 13.
Tool arm drive spindle 12 comprises drive wheel 121, rotating shaft 122, lever arm 123, drive wheel 121 is movably arranged on a cutter base plate 1 by rotating shaft 122, be fixedly connected with drive wheel 121 in the middle part of lever arm 123, the hinged left tool arm 14 in one end of lever arm 123, the hinged right tool arm 15 of the other end of drive spindle 12.Drive wheel 121 rotates under the drive of door machine synchronous belt.
Tool arm connecting rod 13 is arranged on below tool arm drive spindle 12, and the two ends of tool arm connecting rod 13 hinged left tool arm 14 and right tool arm 15 respectively.Tool arm drive spindle 12, right tool arm 15, tool arm pipe link 13 and left tool arm 14 is made to form four-rod linkage structure.
Car door lock 11 comprises lock pedestal 111, hammerlock 112, latch hook 113 and positioning plate 115; Lock pedestal 111 is fixedly installed on a cutter base plate 1, and latch hook 113 is fixedly installed on one end of hammerlock 112, and the other end of hammerlock 112 is rotationally connected with lock pedestal 111.Hinged with right tool arm 15 in the middle part of hammerlock 112, below the position that right tool arm 15 is hinged with hammerlock 112, hammerlock draw-in groove 1121 is set.Car door lock 11 also comprises and the gravity drop hammer 114 that be arranged on hammerlock 112 below mutually vertical with hammerlock 112, and one end of gravity drop hammer 114 is fixedly connected with hammerlock 112.Lock pedestal 111 arranges positioning plate 115, and positioning plate 115 is arranged on the left of gravity drop hammer 114.The side that positioning plate 115 and gravity drop hammer 114 contact all arranges anticollision strip.Car door lock 11 also comprises retracing spring 116, being set in parallel on lock pedestal 111 of retracing spring 116, and connects gravity drop hammer 114 and lock pedestal 111 along the length direction of gravity drop hammer 114.
The working process of a kind of elevator door knife described in the utility model is as follows:
When gate is opened, door machine Timing Belt drives drive wheel 121 to rotate counterclockwise, thus left tool arm 14 and right tool arm 15 are drawn close; Hammerlock 112 rotates counterclockwise under the drive of right tool arm 15, and band moveable lock hook 113 upwards lifts and is separated unblock with locked groove, and appliance contact and touch base disconnect.The croquet that left tool arm 14 and right tool arm 15 clamp layer door drives layer door to open.
When gate is closed, left tool arm 14 and right tool arm 15 gripping layer every ball make layer door close, and door cutter left tool arm 14 when layer door is closed completely is separated with right tool arm 15.To be stuck in hammerlock draw-in groove 1121 and the hammerlock 112 hinged with right tool arm 15 rotates clockwise under the drive of right tool arm 15, gravity drop hammer 114 and retracing spring 114.When latch hook 113 inserts the locked groove of gate, gravity drop hammer 114 and retracing spring 116 apply downward fastening force, keep the lock-out state of car door lock 11.
When gate is not when having the position of layer door, latch hook 113 snaps in the locked groove of gate, cannot open gate.Can prevent car personnel from prying open gate and cause the unexpected accident falling well.
Although describe embodiment of the present utility model by reference to the accompanying drawings, those of ordinary skill in the art can make various distortion or amendment within the scope of the appended claims.
