Description

Slideway hook for door and window

The utility model relates to the door and window part; Particularly relate to the door and window window catch.

Mostly traditional door and window window catch is to be bent by iron bar and forms, and combines by being divided in window catch on the doorframe and window frame and the hook nose on the bar.The major defect of this window catch is simple and crude except that moulding, lack the ornamental aesthetic, the more important thing is and can not arbitrarily adjust with the size of the changes in temperature of weather or wind-force the opening angle of bar; And because of its directly by the screw threads of window catch and hook nose on door and window, it is too concentrated to form origin of force, particularly in the corrosion of wind and rain or constantly rocking down of strong wind, the very easily loosening or fracture of screw directly influences application life of window catch.

The purpose of this utility model is at above-mentioned deficiency, provides a kind of handsome in appearance generous, and quality is solid, origin of force disperses, install firmly, corrosion resistant, wind resistance power are strong, particularly can arbitrarily adjust the door and window window catch of bar opening angle.

Basic design of the present utility model is the door and window window catch of a kind of slide rail type of design.The door and window window catch of this slide rail type can utilize screw and nut between slide mass and the slide rail, and slide mass is fastened on any position of slide rail, thereby according to the needs of wind-force and weather, selects the opening angle of bar.

Accompanying drawing 1 is the overall structure front view of the utility model embodiment 1;

The a of accompanying drawing 2 is vertical views of the utility model embodiment 1; B is its A-A lateral view;

The a of accompanying drawing 3 is vertical views of the utility model embodiment 2; B is the lateral view of its B-B.Mainly shown another kind of locate mode among the figure to slide mass 2.

Following with reference to accompanying drawing, the concrete structure of two embodiment of the utility model is described as follows:

Embodiment 1: as shown in Figure 1, slide rail 1 is that section is

The grooved rail of shape has plural screw in its bottom surface, is anchored on the bar in order to screw.On slide rail 1, setting-in a section and is Shape, and can be along the slide mass 2 of slide rail slip.At the left end of slide mass 2, be the push arm bearing 3 that strikes out vertical configuration, bearing 3 strikes out relative both direction by the difference of left and right door sash.In the centre of slide mass 2, the trip bolt 6 and the wing nut 7 of a location usefulness arranged, form the detent mechanism of slide mass 2, in order to slide mass 2 is fastened on any part of slide rail 1.On push arm bearing 3, move and adorn a reclinate push arm 4 of left end.The left end of push arm 4 moves and adorns a L shaped fastening seat 5.On the bottom surface of fastening seat 5, plural screw is arranged, in order to be fastened on the doorframe and window frame by screw.The difference of fastening seat 5 following left bars and be divided into relative both direction.

The basic structure of embodiment 2 is identical with embodiment 1.Just with the detent mechanism of slide mass 2, change locating pin into by spring reset by trip bolt 6 and wing nut 7.Shown in a and b of Fig. 3, on slide mass 2, have one can be by the locating pin 8 of spring reset, the inner chamber of slide rail 1 has a back-moving spring 9 around locating pin, the bottom surface of slide rail 1 is upwards slightly protruding arc, on its bottom surface, except that the assembling screw of necessity, be separated with the locating hole 10 more than four between going back.

When selecting the structure of embodiment 1 for use, can be fastened on respectively on doorframe and window frame or the bar with the holder 5 and the slide rail 1 of screw by illustrated in figures 1 and 2 with push arm 4 left ends.During door and window, unscrew the wing nut on the slide mass 1 earlier,, select opening angle arbitrarily, then wing nut is screwed and get final product again according to the needs of wind-force or weather.When selecting the structure of embodiment 2 for use, its mounting method is identical with embodiment 1, just when door and window, can extract by the locating pin 8 that will reset shown in Figure 3, when being opened into certain angle, loosening locating pin 8 and it is automatically reset to some locating holes of slide rail bottom surface, get final product.

Important technological parameters of the present utility model and performance are as follows:

1, stretches elongation degree: 160mm～250mm;

2, the opening angle of bar: 0 °～125 °;

3, overall dimensions: 160mm * 30mm * 20mm;

4, specification: can the length of slide rail be made 135mm, 165mm, three kinds of different specifications of 195mm respectively according to the different needs of door and window.

It is generous that the utility model is handsome in appearance, and whole body is electroplated, and is anticorrosion durable, easy by adorning, use flexibly, origin of force disperses, wind resistance power is strong.Applicable to wooden doors and windows or steel plastic door and window.
