Background technology
Elevator install and repair and maintenance time, often need to open hoistway door and enter sedan-chair top or car carries out operation, have the needs in order to operation in many situations, Room door or gate must be made to remain on the state opened.For Room door, if without the obstruction of external force, closed under the drive of the self-closing power that Room Men Zehui provides at weight, for preventing the Room door from closing, repair and maintenance personnel must overcome Room door self-closing power by certain instrument is installed.In the installation repair and maintenance process of reality, repair and maintenance personnel are installed normally be inserted in a screwdriver in the gap of lading door dill chute and Room every leg, rely on the friction force after being seated to overcome the self-closing power of Room door, prevent the Room door from closing, but this method is very easy to damage Room every leg and lading door dill, and the installation repair and maintenance personnel that experience is slightly short of a little are also not easy to grasp the dynamics being seated screwdriver, location may be caused unreliable, need repeatedly to operate and could more firmly locate.Be exactly in addition in the process of operation, repair and maintenance personnel are installed touch vibrations that Room door produces the gap between screwdriver and lading door dill chute, Room every leg can be made to change, produce and loosen, thus this locate mode was lost efficacy, affect normal operation, even cause potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of elevator door locating clip, and its location is reliable, and low-profile, is easy to carry.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of elevator door locating clip, comprise the fixed mount that cross-sectional plane is a few font, fixed mount roof central authorities offer centre hole, in centre hole, slidable fit has screw rod, screw rod upper end is fixed with handle, screw rod lower end is provided with clamping slide block through after centre hole, wherein clamp slide block central authorities and be provided with the screw concentric with screw rod, screw rod is located in screw, be positioned at screw rod both sides in described fixed mount to be hinged respectively clamping plate, it is inverted v-shaped that two clamping plate are clipped in clamping slide block both sides, two clamping plate upper ends and fixed mount are hinged, the lower end of clamping plate is stretched out from the opening of fixed mount lower end, the madial wall of two clamping plate respectively with clamping slide block two side moving contact.
Described two clamping plate are hinged on fixed mount by straight pin, fix respectively between the both ends of the wherein biside plate of fixed mount one with the straight pin of the side plate place plane being perpendicular of fixed mount, described clamping plate upper end all offers two pin-and-holes corresponding with two straight pins, and the diameter of pin-and-hole is greater than the diameter of straight pin thus two clamping plate can be swung on straight pin.
Described two clamping plate madial wall central authorities all offer groove, and the space between two grooves constitutes the passage that screw rod passes through.
The madial wall of described two clamping plate all offers chute, and the upper limb of the bottom surface of chute is crossing with the madial wall of clamping plate, and the two side of clamping slide block contacts with slide.
Described fixed mount roof is fixed with the back-up ring concentric with screw, and shield ring sleeve is outside screw rod.
Described clamping plate are made up of brass plate.
The present invention is provided with the screw concentric with screw rod in clamping slide block central authorities, screw rod is located in screw, during turning handle, the clamping plate being closely attached on both sides can rise by clamping slide block, and the clamping plate that simultaneously can head on both sides make the angle of two clamping plate increase, continue to rotate, until clamp between two clamping plate and sill chute two side, and make this gripping power be enough to overcome the self-closing power of Room door, make Room door remain on required position, thus can stop that Room door is self-closing, be convenient to repair and maintenance personnel operation is installed.The present invention can rely on and screw or unscrew screw rod and realize fixing, and simple to operate, location is reliable, not easily loses efficacy, not easy damaged sill, and low-profile, be easy to carry, economical and practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-4, a kind of elevator door locating clip, comprise the fixed mount 1 that cross-sectional plane is a few font, fixed mount 1 roof central authorities offer centre hole, and in centre hole, slidable fit has screw rod 2, and screw rod 2 upper end is fixed with handle 3, screw rod 2 lower end is through being provided with clamping slide block 4 after centre hole, wherein clamp slide block 4 central authorities and be provided with the screw 5 concentric with screw rod, screw rod 2 is located in screw 5, and screw rod 2 is connected by screw thread, screw with clamping slide block 4.Be positioned at screw rod both sides in fixed mount 1 to be hinged respectively clamping plate 6, clamping plate are made up of brass plate, brass toughness is better, not easy damaged sill, it is inverted v-shaped that two clamping plate 6 are clipped in clamping slide block both sides, two clamping plate 6 upper ends and fixed mount 1 are hinged, and the lower end of clamping plate is stretched out from the opening of fixed mount lower end, the madial wall of two clamping plate 6 respectively with the two side moving contact of clamping slide block 4.
Two clamping plate are hinged on fixed mount 1 by straight pin 7, fix respectively between the both ends of the wherein biside plate of fixed mount 1 one with the straight pin 7 of the side plate place plane being perpendicular of fixed mount, described clamping plate 6 upper end all offers two pin-and-holes 8 corresponding with two straight pins, the diameter of pin-and-hole 8 is greater than the diameter of straight pin, such two clamping plate not only can horizontally slip along straight pin, and also can swing certain angle on straight pin.
The madial wall central authorities of two clamping plate 6 all offer groove 9, and the space between two grooves 9 constitutes the passage that screw rod passes through, and is convenient to screw rod and passes through.
The madial wall of two clamping plate all offers chute 10, the upper limb of the bottom surface of chute is crossing with the madial wall of clamping plate, the two side of clamping slide block 4 contacts with slide, and chute 10 plays position-limiting action to clamping slide block 4, can guarantee that clamping slide block 4 slides up and down along two clamping plate 6 like this.
Fixed mount 1 roof is fixed with the back-up ring 11 concentric with screw, and back-up ring 11 is enclosed within outside screw rod, and back-up ring plays position-limiting action, can limit the shift position that screw rod 2 vertically puts down, and avoids clamping slide block 4 excessively to glide and away from clamping plate.
When the present invention specifically uses, as shown in Figure 5, clamp slide block 4 during initial condition and be positioned at screw rod lower end, now the angle of two clamping plate 6 is smaller, first fixed mount 1 is placed on hoistway door sill 12, then the lower end of two clamping plate 6 is placed in sill chute 13, carrying handle makes clamping slide block 4 contact with the chute 10 on two clamping plate 6, turning handle 3 drives screw rod 2 to rotate, handle 3 is contacted with back-up ring 11, now screw rod 2 can only rotate and can not move up and down, then handle is rotated further, clamping slide block moves up under the effect of screw rod, clamping slide block orders about the clamping plate be adjacent in its both sides and rises, the clamping plate simultaneously heading on both sides make the angle of two clamping plate increase, continue to rotate, until clamp between two clamping plate and sill chute two side, the friction force at two places makes in a lading door dill chute of locating clip clamping, and make this gripping power be enough to overcome the self-closing power of Room door, Room door is made to remain on required position, thus stop that Room door is self-closing, be convenient to repair and maintenance personnel operation is installed.
