Description

A kind of sash lock

The utility model relates to a kind of sash lock.

Common sash lock mostly is bolt-type or spring, and simple bolt-type sash lock is because not attractive in appearance, yielding more and more rare in practice.And the spring sash lock especially is widely applied in the sliding sash of materials such as aluminium alloys because easy to use, good looking appearance uses more and more widely.Aforesaid various sash lock is an integrative-structure, by aid or destroy lock body structure and just it can not taken apart, will change whole sash lock like this when a damage parts wherein, and both inconvenience had also improved use cost.

The purpose of this utility model is in order to provide a kind of sash lock of simple in structure, easy accessibility.

Main technical schemes of the present utility model is: this sash lock comprises lock body, the dead bolt that can slide in the chute of lock body, between dead bolt tail end and the chute end spring is arranged, there is "T"-shaped through hole the chute top, also have one laterally to be "T"-shaped jack on the dead bolt, the jack lower end has and same width of the big end of "T"-shaped jack and the translot that communicates, the fork of lock handle passes through hole and inserts in the jack, the fork end has the shifting block of width greater than the fork width, shifting block is positioned at translot and against the translot end, the height of translot is greater than the shifting block longitudinal size.

The utility model easy accessibility need not needn't destroy lock body by aid.When dismounting, earlier dead bolt is pressed into chute, it is right that the "T"-shaped through hole at big end of "T"-shaped jack on the dead bolt and chute top is rectified greatly, shifting block on the fork is moved into the big end of "T"-shaped jack in translot, lock handle can be transferred in dead bolt, lock body, simultaneously, dead bolt also can be extracted out in chute, thereby whole sash lock has been disassembled into single part.Installation process is just in time opposite with it.So can both change easily during arbitrary damage parts in the utility model, especially the spring fatiguability lost efficacy, and so just needn't therefore change whole sash lock, thereby reduce the use cost of sash lock greatly.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the structural representation of an embodiment of the utility model;
