Description

Self-supporting window catch with bolt

The utility model relates to a kind of annex of building, particularly a kind of self-supporting strap bolt window catch.

Existing window catch is to be made of support hook and shackle, and its weak point is: because shackle is bigger, under big wind action, the sash after rising to the bait shakes bigger, and noise is arranged, and needs two hands to operate the inconvenience of rising to the bait simultaneously, can only make window catch and use, and function of use is single.

The purpose of this utility model designs a kind of simple in structure, easy to use exactly, and function is many, supports the firm self-supporting strap bolt window catch of sash.

The utility model purpose realizes by following structure: the support bar that self-supporting strap bolt window catch includes the window catch fixture and is rotationally connected, it is characterized in that: two support bars are rotationally connected by pin, have a recess to engage with the spacing card of another support bar end correspondence position on a support bar; When the utility model uses, the two ends of two support bars can be consolidated on sash and fan frame, be pushed open sash, two support bar rotating opening firmly support sash.

The utility model compared with prior art has following advantage:

1, pushing sash open can support automatically, fixing, thus easy to operate, firm supporting.

2, structure is simpler.

Description of drawings of the present utility model is as follows:

Fig. 1 is state diagram to be opened of the present utility model;

Fig. 2 is open mode figure of the present utility model;

Fig. 3 is locking-in state figure of the present utility model;

Fig. 4 is full holding state figure of the present utility model;

Among the figure: 1, window catch fixture, 2, support bar, 3, pin, 4, recess, 5, spacing card, 6, locator card, 7, limit notch.

Below in conjunction with drawings and Examples structure of the present utility model and principle are described further:

As shown in Figure 1: it is to be rotationally connected by pin 3 with 2, two support bars of support bar that are rotationally connected that the utility model includes window catch fixture 1, has a recess 4 to engage with the spacing card 5 of another support bar end correspondence position on the support bar; More convenient in order to use, can on a support bar, preset a limit notch 7 and engage, to set up window bolt function of the present utility model, as shown in Figure 2 with the locator card 6 of another support bar shaft correspondence position.

When using the utility model, by fixture support bar is separately fixed on window frame and the sash, when opening sash, after two support bar rotations are stretching, spacing card engaging by the recess on the support bar and another support bar end is as shown in Figure 4 spacing, act on when windowing direction when wind-force this moment, and support bar vertically forms pulling force, when wind-force acts on pass window direction, support bar vertically forms pressure, all can not blow sash, have only when manpower laterally promotes the support bar connecting portion, support bar rotates just mutually can close sash, as shown in Figure 2, after closing sash, two support bars overlap, and the limit notch 7 on the support bar engages with locator card 6 on another support bar shaft, be center rotary supporting rod 180 ° with the run-on point on the fixture this moment, sash is lockable, to replace the window bolt, as shown in Figure 3.
