Abstract

The utility model relates to an automatic bolt, which is characterized in that automatic bolt comprises a bolt seat 1 which is fixedly connected to a window leaf, a pin body 3 which is hinged with the bolt seat 1 by a pin shaft 2, a counterpoise 4 which is arranged on the upper end of the pin body, and a window fastener 5 which is fixedly connected to a sash frame by screws. The utility model has the advantages of simple structure and self closing at the time of blowing wind. When the deformation of window leaf occurs, by slightly adjusting the position of the window fastener, the window leaf can be normally used.

Description

Automatic bolt

The utility model relates to a kind of self-locking gear of window, particularly relates to a kind of automatic pinning.

At present, people's locking window generally is to adopt a kind of latch, and is inevitable earlier with the window closure when need locking window, then, holds the window leaf on the other hand, and firmly by advancing latch, it is very inconvenient to use on the other hand.Particularly open wide at the window leaf and do not go up window catch and run into again when blowing hard, the window leaf just can collide with the wind, causes the accident of bumping bosom window leaf or glass to take place.Chinese patent disclosed " automatic pinning " is though CN87201342U can overcome above-mentioned deficiency, but because its complex structure, inserted link and the frictional force of installing between base plate are big, quick abrasion, application life is short, and switch is un-skill, especially when the window phyllomorphosis, compensation is adjusted in this latch inconvenience, so be difficult to extensive use.

It is a kind of simple in structure that the purpose of this utility model is to provide, and opens light and flexible, with low cost, and chance wind is self-closing, and can adjust the automatic pinning that can normally use slightly under window phyllomorphosis condition.

The purpose of this utility model is to realize like this.That is: this automatic pinning has a plug housing that is fixed on the window leaf, and hinged with it shank is contained in the counterweight handle of shank upper end, and buckles by the window that screw is fixed on the window frame.When closing the window leaf, only need pinch the counterweight handle the people, let go after being pulled to make position, under the action of gravity of counterweight handle, the shank hook portion just embeds in the window catching groove, realizes locking.Do not hang window catch when the window leaf and meet again when blowing hard, insert automatically in the window catching groove window leaf just can slip over window frame under the wind-force effect after, realize closing automatically.

The utility model compared with prior art, have rational in infrastructure, simply, easy to manufacture, safe and reliable, chance wind self-closing characteristics, especially window are buckled and are provided with two slotted holes, in the window phyllomorphosis, in the time of can not normally using, only need unclamp screw, adjust the window button bit slightly and put, can realize the normal locking of window leaf.

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is an agent structure schematic diagram of the present utility model;

Fig. 2 is the front view of window button of the present utility model;

Fig. 3 is Fig. 2 A-A echelon sectional view.

Below with reference to accompanying drawing concrete structure of the present utility model is further described.

Referring to accompanying drawing, a kind of automatic pinning of the utility model, by be fixed in plug housing 1 on the window leaf, by the shank 3 that bearing pin 2 and plug housing are hinged, be contained in the counterweight handle 4 of shank 3 upper ends, and be fixed in window on the window frame by screw and buckle 5 and form.Plug housing 1 can be made into rectangle or quincunx; Shank 3 is operates on shape; Counterweight 4 can be sphere or has the bird shape of decoration function, 12 symbolic animals associated with a 12 year cycle shape; Window button 5 longitudinal sections are L-shaped, have two slotted holes on it at least, a groove, and the purpose that slotted hole is set is: after the window phyllomorphosis, can unclamp screw, adjust the position of window button slightly, can normally use.

Claims

1, a kind of automatic pinning is characterized in that a plug housing (1) that is fixed on the window leaf, and hinged with it shank (3) is contained in the counterweight handle (4) of shank upper end, and buckles (5) by the window that screw is fixed on the window frame.

2, according to the described automatic pinning of claim 1, it is characterized in that window button (5) longitudinal section is L-shaped, have two slotted holes on it at least, a groove.

3,, it is characterized in that shank (3) is to operate on shape according to the described automatic pinning of claim 1.
