Abstract

The utility model provides a lock of an aluminum alloy window, which is composed of a lock tongue hole which is arranged on a window frame, lock tongues which are arranged on a sash and a rotor plate which is connected with the lock tongue and is fixed on a shaft of a rotating shaft. The utility model is characterized in that a spring is respectively arranged on an upper lock tongue and a lower lock tongue; the springs are respectively connected both ends of the rotor plate by a connecting rod; the utility model can simultaneously lock the upper end and the lower end of the sash to make that the utility model has stronger anti-wind pressure performance; when a window is opened, as long as the rotating shaft is rotated, the upper lock tongue and the lower lock tongue can be simultaneously opened; therefore, the utility model has the advantages of simple structure, convenient operation, long service life and beautiful appearance; the utility model is suitable for any aluminium alloy window.

Description

A kind of aluminium alloys sash lock

The utility model relates to a kind of sash lock, especially a kind of sash lock that is used on the aluminium alloys casement window.

Highrise building is the symbol of modern metropolitan cities, and people live in such environment, all wishes to possess certain living space, and require this space to have sufficient sunlight and air, and, have only the open area that strengthens window for highrise building, could satisfy this hope of people.Though existing sliding aluminium alloy window has increased the area of window, the area of opening has only 50% of whole window, perhaps has only 30%.Though open the folding window open area and reach 100% and aluminium alloys is flat, but for this flat big sash of opening, close in the time of afterwards can only pinning lower end or upper end with existing sash lock, can not stand the eminence blast, have only the upper and lower end of sash to pin simultaneously, lock surely, could guarantee to fan greatly the aluminium alloys casement window and have short enough Wind-Pressure Resistance abilities, therefore, must improve existing sash lock, put down and open applying of folding window otherwise will restrict aluminium alloys.

The purpose of this utility model is to provide a kind of can pin the big sash of upper and lower aluminium alloys simultaneously, and the sash lock of energy automatic locking window.

The utility model is achieved in that it is by the dead bolt hole and the dead bolt of being located on the sash be located on the window frame, and link to each other with dead bolt and the rotor that is fixed on the turning handle axle constitutes, it is characterized in that upper and lower dead bolt is provided with spring, and be connected with the rotor two ends by connecting rod respectively.Described upper and lower dead bolt is provided with boss, is used to be provided with spring, and the tongue end of dead bolt is provided with domatic, so that can slip into automatically in the dead bolt hole, the dead bolt tail end links to each other with connecting rod one end, and the connecting rod other end is connected with rotor, up and down dead bolt and on spring be located at respectively in the dead bolt seat; Described dead bolt seat is made of pedestal and the cavity be located in the pedestal, and cavity is used to put dead bolt, and pedestal one end is provided with through hole, so that the domatic tongue end of dead bolt freely stretches, the pedestal other end is provided with slide block, and slide block is provided with through hole, is connected with connecting rod so that the dead bolt tail end passes this hole; The rotor that is connected with connecting rod is fastened on the turning cylinder of turning handle, so that can rotate with the rotation of handle, turning handle and axle thereof are fixedly connected on the aluminum window sectional by locking closure and staple.

The utility model compared with prior art has following advantage and extremely long-pending effect: because the upper and lower end of this lock is equipped with the dead bolt which is provided with spring by lock respectively, and this upper and lower dead bolt is connected rotor two ends on the turning handle axle by length-adjustable connecting rod respectively again, therefore, as long as turning handle, can open upper and lower dead bolt simultaneously, it is very convenient to window.Lock is during window, and domatic by upper and lower dead bolt tongue end regained dead bolt, and upper and lower dead bolt is inserted in the dead bolt hole on the upper and lower window frame simultaneously, realizes that automatic locking lives the purpose of upper and lower window, makes aluminum window have higher Wind-Pressure Resistance ability.Other the utlity model has simple in structure, and is easy to operate, long service life, and characteristics such as both artistic and practical are applicable to any aluminum window.

Fig. 1 is the structural representation of the utility model.

Below in conjunction with accompanying drawing the utility model is described further, is not limited only to this but hold within the utility model.

Among the figure, 1 is the window frame of aluminum window, 2 is the dead bolt seat, be located at respectively on the aluminum window sectional 3, following two ends are provided with cavity 17 in this dead bolt seat, and an end of dead bolt seat has through hole 18, the other end of dead bolt seat is equipped with slide block 15, having through hole 16,4 on this slide block is dead bolt, places the cavity 17 of dead bolt seat, dead bolt 4 is provided with boss 9, be used to be provided with spring 8, it is domatic 9 that the tongue end of dead bolt is made as, and flexible in the through hole 18 of dead bolt seat 2 one ends, the tail end of dead bolt is located at through hole 7, and the through hole 16,5 that this tail end passes on the dead bolt seat slide block 15 is the connection steel wire, and it is fixing that the one end passes the through hole 7 of dead bolt tail end, the other end is fixed on the rotor 6, this rotor 6 is fastened in the rotating shaft 12, and rotates thereupon, and rotating shaft 12 is fixed in the aluminum window sectional 3 by locking closure 11, its outer end is connected with handle 13, during turning handle 13, rotating shaft 12 is also rotated thereupon, and locking closure 11 is fixed on the sash profile by staple 14.
