Abstract

The utility model discloses a stepless positioning device for opening and closing doors or windows, which is designed in an optimized way. The utility model is composed of guiding rods (1), fixing plates (2), crankshaft blocks (3), connecting bolts (4), adjusting nuts, stopping pads, fixing bolts, etc. The utility model overcomes the defects of the existing positioning devices of doors and windows, such as the type of a wind hook, the type of a metal supporting bar with a plurality of holes, the type of a spring and a ball bearing, etc. which belong to the step orientation, and a four-bar mechanism is positioned through screwing nuts manually. The stopping pads of the utility model are made of flexible materials. The stepless automatic orientation is realized by the stronger friction force of the pads. The force of the orientation can be adjusted, and the force of the orientation can not change for a long time once adjusted. The doors and windows can be positioned automatically after opened and closed by any angles, so the nuts need not to be screwed at any moment. The utility model has the advantages of simple and compact structure and reliable orientation.

Description

Stepless automatic location device for opening and closing door or window

The utility model is a kind of switching automatic positioning equipment that uses on door and window.

Existing door and window positioner has following several types, a type; Window catch is inserted Xiao Dingwei, two types are metallic struts formulas, on pole, be shaped on a plurality of holes, be enclosed within on the fixing alignment pin door and window is located, three types are four-bar mechanisms, the fastening nut location, back of windowing, four types are to use the steel ball that spring is housed, spring into when windowing and realize the location in the eyelet of diverse location, five types are other type ratchets, and pawl type has level to decide device.

One type has only the window standard-sized sheet and closes location, two positions of window, with the passing of time easily loosening, the broken glass of shake, advantage is inexpensive, two types can only be located on several limited positions, and rod member is longer, and rod member stretches to indoor one section behind the window of pass, the clothing of caring for easily again neither attractive in appearance, the stepless location though three types have realized windowing needs fastening nut, inconvenience during the location, and rod member is long, four types can only be located on limited eyelet position, and five types also are that a grade positioner is arranged, and the purpose of this utility model is the weak point at above-mentioned locator, improve and optimizate design, realization is windowed the position in 90 degree scopes, " the stepless automatic location " that can regulate arbitrarily, and the size adjustment of detent force is convenient, regulating the back detent force remains unchanged for a long period of time, it is simple and compact for structure attractive in appearance, and is easy to use and reliable, closes the window back-guiding rod and places along window, can not stretch to indoor, can be equal to or slightly greater than behind the door and window standard-sized sheet 90 the degree.

The designed door and window of the utility model opens and closes stepless automatic positioning equipment, by guide rod (1), and fixed head (2), crank piece (3), binder bolt (4) adjusting nut (5) stop pad (6), plain washer (7), set bolt (8) is formed.End at guide rod has a hole, eyelet is slightly larger than the size of set bolt, guide rod has the hollow elongated slot of one " yi word pattern ", fixed head is fixed in the horizontal windows side with wood screw, a set bolt is arranged on it, set bolt is inserted locking nut in the eyelet of guide rod, can freely rotate for the spindle guide bar with the bolt, one end of crank piece is bent into the right angle of 90 degree, be shaped on 2--3 eyelet, with wood screw crank piece and window frame fixed, the other end of crank piece is shaped on hole, a garden, binder bolt penetrates in the crank piece hole, put the stop pad and insert in the yi word pattern elongated slot of guide rod, put plain washer, put adjusting nut, the crank piece is slidably reciprocated in the elongated slot of guide rod, because stop washer is made with nonmetal flexible material, has bigger friction factor and gentle a piece of wood serving as a brake to halt a carriage, utilizes this characteristic, the degree of tightness of adjusting nut can realize stepless automatic location reliably when sliding in the word length groove of crank piece at guide rod.The big or small available adjustment nut of detent force is regulated, and one after setting up, and its detent force can remain unchanged in the long term, no longer need turn adjusting nut at any time, can realize the opening of doors and windows automatic location of size arbitrarily.Easy to use, simple in structure, if unexpected strong wind of chance or unexpected strength cause the pass window, because the big cushioning effect of stop pad friction factor also can not cause the damage of window frame and glass.

The explanation of accompanying drawing drawing:

In the accompanying drawing

1, guide rod

2, fixed head

3, the crank piece

4, binder bolt

5, adjusting nut

6, the stop pad

7, plain washer

8, set bolt

9, loose-leaf

10, following horizontal windows side

11, following horizontal sash

12, wood screw

In conjunction with Figure of description embodiment of the present utility model is described.

Press the device of accompanying drawing, guide rod (1) is attached on the fixed head (2), with wood screw (12) fixed head is installed in the lower horizontal timber window side (10), connecting bolt (4) is penetrated in the crank piece (3), put stop pad (6), penetrate the yi word pattern elongated slot of guide rod (1) from the below, crank piece (3) is fixed on down on the horizontal sash (11), put plain washer (7) and adjusting nut (5) again, just can realize the Switch for door and window stepless automatic location of size arbitrarily by said apparatus assembling back.

Slightly tighten adjusting nut, just can obtain bigger friction detent force, simple in structure, durable in use, the location is reliable.Above-mentioned parts stop pad (6) adopts nonmetal flexible material such as industrial rubber, and other is metal material and makes.

Claims
