Description

A kind of automatic window catch

The utility model relates to a kind of automatic window catch, belongs to the improvement of pushing formula door and window locking means.

Existing pushing formula door and window locking means is varied, and its structure is generally movable lock body and the fixedly combination of lock body, by the eave tile on the movable lock body and fixedly the dog hole cooperation between the two of lock body realize shutting and opening of push-pull door and window.Chinese patent (patent No. is ZL9522813.8) discloses a kind of lock for windows, it is mainly reached by lock, button forms by hook back-moving spring and spring flap, the one limited block formation latch hook that stretches out is arranged on the button, the assembling more complicated of the spring of the lock for windows of this structure, only realize resetting by single spring, stressed relatively nervous, cause easily and block, simultaneously because press button area is little, the phenomenon that in manipulating process, occurs the latch hook beat easily, and the operating space is little, operation is required great effort, inconvenience.

The purpose of this utility model provide a kind of production, easy to assembly simple, manipulate flexible, laborsaving, reliable automatic window catch.

The utility model by lock body, activity collude, fixed hook forms, wherein lock body comprises panel and mount pad, have elongated hole on the panel, activity is colluded and is comprised pressing board, eave tile, eave tile is vertically set on pressing board one side, and pressing board is by in the elongated hole of panel that is arranged on flexible member on the mount pad and is movably arranged on lock body.

The utility model is because the structure that adopts pressing board and eave tile to be wholely set, only need push pressing board just can realize opening sash lock easily, and realize that by two back-moving springs it resets, simple in structure, easy to assembly, flexible operation, reliable, cost is low, simultaneously because the pressing board face is more roomy, more laborsaving, safety during operation.

Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:

Fig. 1 is that master of the present utility model looks schematic diagram;

Fig. 2 is a schematic rear view of the present utility model;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the B-B sectional view of Fig. 2;

As Fig. 1-shown in Figure 4, the utility model is by by lock body (1), (2) are colluded in activity, fixed hook is formed, wherein lock body (1) comprises panel (11) and mount pad (12), panel has elongated hole on (11), activity is colluded (2) and is comprised pressing board (21), eave tile (22), eave tile (22) is vertically set on pressing board (21) one sides, pressing board (21) is by in the elongated hole of panel (11) that is arranged on elastic device (3) on the mount pad (12) and is movably arranged on lock body (1), and pressing board (11) back side is provided with the spacing edge that protrudes from elongated hole, and eave tile stretches out lock body from mount pad (12) rear portion.For simplifying production technology, ease of assembly, the mount pad (12) of lock body (1) are the hollow cavity that is arranged on corresponding elongated hole position, lock body (1) panel (11) back, and its two ends are respectively equipped with supporting traverse (121), and above-mentioned flexible member is installed on the crossbeam.For guaranteeing the reliability of flexible member (3) action, be respectively equipped with flexible member (3) at the elongated hole two ends of lock body (1), flexible member (3) is compression spring (3), this compression spring (3) lower end is installed in supporting traverse (121) cover for seat (122) of mount pad (12), and its upper end is nested with the stem stem (24) at pressing board (21) back side.Steady, reliable for guarantee that pressing board (21) moves in panel (11) elongated hole, mount pad (12) the side plate medium position of lock body (1) is provided with gathering sill (13), the position of the corresponding gathering sill of pressing board (21) side (13) is provided with leads a piece (23), and this is led in a piece (23) the embedding gathering sill (13) and can slide in gathering sill (13).
