The purpose of this utility model is for overcoming the above-mentioned shortcoming of existing slide window lock, a kind of slide window lock of good reliability being provided.

The utility model is achieved in that sash lock by lock body, and snap close is formed.Lock body is equipped with the latch hook of the band back-moving spring of two symmetric arrangement.When window was closed, two latch hooks slipped in the snap close automatically, and under the elastic force effect of back-moving spring, two latch hooks fasten snap close respectively in opposite direction.This structure makes lock body or snap close which side all have at least a latch hook to fasten snap close to the changing of the relative positions towards, thereby has improved the reliability of sash lock.

The utility model compared with prior art has the following advantages: 1. reliability height, theftproof performance is good.2. easy to use.Latch hook fastens snap close automatically when closing window, need not the special action that shuts.

Fig. 2 is a buckle structure schematic diagram of the present utility model.

Fig. 3 is that the latch hook and the snap close of lock body fastens schematic diagram.

Fig. 4 is the A-A sectional drawing of Fig. 1.

Fig. 5 is a latch hook and the schematic diagram that connects of spring.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

With reference to Fig. 1, Fig. 2, Fig. 3, sash lock is made up of lock body 1, snap close 2.Lock body 1 is provided with two symmetrically arranged latch hooks 3.The spacing hole 4 that latch hook 3 passes on the lock body wall is protruding, and its end is actively connected on the lock body 1 by bearing pin 5, and latch hook 3 can rotate around bearing pin 5.With reference to Fig. 3, Fig. 5, back-moving spring 6 is enclosed within on the bearing pin 5, and an end acts on the latch hook 3, and the other end acts on the lock body 1.Two latch hooks 3 open respectively round about under the effect of back-moving spring 6, and are limited in the certain angle by spacing hole 4.There is inclined-plane 7 at the hook end place of two latch hooks 3.When closing window, latch hook 3 slips in the snap close 2 automatically by inclined-plane 7.

With reference to Fig. 1, Fig. 4, the front of lock body 1 is provided with slide switch 8.Slide switch 8 is divided into two joints, small one and large one, trifle is enclosed within the big joint, can slide mutually between two joints.Between two joints, be equipped with spring 9.End at large and small joint respectively is provided with latch hook plectrum 10.When windowing, as long as compression slide switch 8 two ends just can be stirred two latch hooks 3 by latch hook plectrum 10 it is drawn close, this moment, latch hook 3 broke away from snap close 2, can draw back sash.Unclamp slide switch 8 after windowing, slide switch 8 resets under the effect of built-in spring 9, and latch hook 3 resets under the effect of back-moving spring 6 simultaneously.With reference to Fig. 3, Fig. 4, between two latch hooks 3, be provided with spacer pin 11.Spacer pin 11 is vertically fixed on the lock body 1.Its effect is to prevent that the situation that causes greatly inadequately breaking away from snap close owing to one of them latch hook actuating length when compression slide switch 8 from producing.
