Abstract
The utility model relates to a positioning device on the way of opening and closing a house door, particularly an optionally stopping device of a house door, which can make a house door after opened stopped in any position. In the utility model, the lower end of the side edge of the house door is provided with a lifting rod which is supported by a bracket, a spring and a stop plate in the position which takes a rotating shaft of the house door as a center and the house door as a rotating radius, wherein, the spring is sheathed on the periphery of the lifting rod, and the middle part of the lifting rod is provided with a partition plate which divides the spring into a reset spring and a stop spring. The lifting rod penetrates through holes which are respectively arranged on the upper and the lower ends of the bracket. The root of the upper end of the bracket is provided with a rectangular hole. The tail part of the stop plate penetrates through the rectangular hole. The utility model is arranged in the position of the maximum force arm of the rotating radius of the house door. When lifted, the lifting rod is treaded by a foot, so that the other end of the lifting rod contacts the ground, and the maximum friction can be generated to make the house door stopped at a positioning point.
Description
Technical field:
The utility model relates to the positioner in the door switch way, refers in particular to make door rest on any stop device of door of optional position after unlatching.
Technical background
The door in present all kinds of houses is except closing fully and opening wide this two states fully, also need door is opened to certain angle, work as the part sight line in order to direction or the screening of regulating air intake, that door always can not be stopped by certain angle is motionless but the door that has is because installation question or wind-force cause, promptly allow to stop at certain angle, door will be blown or closes or unlimited fully if air-flow is excessive when blowing, send irritating impact sound, at this moment can establish obstruction that barrier door rotates temporarily in the front and back of door or hold the student and fill in obstruction in the slit, this interim way can be brought inconvenience to the people.
Summary of the invention
The purpose of this utility model is improved at deficiency that exists in the technical background and problem, provides a kind of simple and reasonable, any stop device of performance practical and reliable door.
The technical solution of the utility model is: in lower end, reveal limit, with the door pivot is that the center is radius of gyration place with the door, the elevating lever that installation is supported by support, spring and locking plate, wherein spring housing is in the elevating lever periphery, the elevating lever middle part has a shim that spring is divided into back-moving spring and retaining spring, the support upper and lower end respectively has a hole elevating lever to pass in the hole, and support upper end root has a rectangular opening, and the locking plate afterbody passes in the rectangular opening.
The utility model is installed in the radius of gyration of door, the maximum arm of force place, make the other end of elevating lever touch ground down with foot-operated during lifting, can produce maximal friction, make door be parked in the place, location, because elevating lever is with spring outward, back-moving spring can make elevating lever produce power upwards, retaining spring also can produce upwards power and locking plate upwards be lifted all the time block lifting and can not rise, can securely door be positioned at as you werely, because locking plate is movable hanging on the support, elevating lever can lift elevating lever under the tension effect of back-moving spring when depressing locking plate, break away from ground, at this moment door can rotate.
