Description

Safety setting window catch

The utility model relates to the window catch that a kind of opening of doors and windows supports, particularly a kind of safe positioning window catch that can make the opening of doors and windows positioning supports.

Existing door and window window catch generally all adopts hook or fish tail to support, owing to be that a wood screw is connected in window frame, and the excesssive gap between hook, window is easily blown and is pulled when blowing hard, and window-glass is easily damaged by wind because of window; And after hanging up, window can only have a fixing louver angle, uses extremely inconvenient.

The purpose of this utility model designs a kind of automatic support window exactly, uses and stablizes firmly, and the safety location envelope hook of a plurality of unlatching window angles is arranged.

The purpose of this utility model realizes by following structure: safe positioning window catch is that upper supporting piece and the lower support element that an end links together formed, on lower support element, have shrinkage pool, at upper supporting piece upper concave hole correspondence position trapezoidal hole is arranged, the location round end of trapezoidal hole is passed in the handle screwed connection, be with holddown spring on the location round end in trapezoidal hole, during use, to go up, on the one end end fixed casement window framework of lower support element, when opening window, the compacted spring of the location round end of upper supporting piece extrudes in the shrinkage pool that holds out against on lower support element, thereby reach the fixedly purpose of window, for window is opened a plurality of orientation angles are arranged, the solid first-class branch of arc of movable end that can be on lower support element have a plurality of shrinkage pools, makes when the location round end is stuck in different shrinkage pool the opening angle difference of window, reach purpose easy to use, in the time will closing window or change the window opening angle, can upwards mention handle compression holddown spring, the location round end leaves shrinkage pool then can.

The utility model compared with prior art owing to the structural orientation that adopts shrinkage pool and location round end, thereby has following advantage:

1. easy to use, can make the location round end be stuck in location in the shrinkage pool automatically, the window opening angle is more, and positioning security is stable.

2. simple in structure, manufacture easier.

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

Fig. 1 is the novel vertical view of this reality;

Fig. 2 is the utility model sectional side view;

1 lower support element, 2 shrinkage pools, 3 upper supporting pieces, 4 connectors, 5 trapezoidal holes, 6 location round ends, 7 holddown springs, 8 handles among the figure.

Below in conjunction with drawings and Examples the utility model is done a further description:

As shown in Figure 1: safe positioning window catch is made up of lower support element 1 and upper supporting piece 5 that connector 4 is rotationally connected an end, end at lower support element is circular arc, concentric five equilibrium has shrinkage pool 2 on its circular arc, in order to make the window positioning security reliable, can be enough big with the most large and small head and the tail shrinkage pool of window opening angle is opened.Correspondence position at the upper supporting piece upper concave hole has trapezoidal hole 5, and the location round end passes trapezoidal hole and is fixed in the trapezoidal hole by handle 8 screwed connections.In trapezoidal hole, be with a holddown spring 7 on the setting circle head, be stuck in the shrinkage pool, as shown in Figure 2 thereby the setting circle crown is gone out trapezoidal hole.

Claims (3)

1, a kind of safe positioning window catch, it is characterized in that: this window catch is made up of upper supporting piece 3 and lower support element 1 that connector 4 is rotationally connected, shrinkage pool 2 is arranged on lower support element, at upper supporting piece upper concave hole correspondence position one trapezoidal hole 5 is arranged, in trapezoidal hole, be installed with location round end 6 and holddown spring 7, on trapezoidal hole, have one with the handle 8 of location knob screwed connection.

2, safe positioning window catch as claimed in claim 1 is characterized in that: shrinkage pool 2 grades are separately on the arc of the garden, end of lower support element.

3, as claim 1,2 described safe positioning window catches, it is characterized in that: the head and the tail shrinkage pool on the end circular arc of lower support element is bigger.
