Abstract

The utility model relates to a position-limiting window hinge. The position-limiting window hinge consists of a hinge seat, a central shaft, a hinge, a slider, and a rotating body on one side of the hinge is sleeved outside the central shaft. And it is connected with the rotation of the central axis. The two ends of the hinge seat also have rotating bodies. The body is provided with a plurality of limiting grooves, the rotating body of the hinge is provided with a slide groove, and the slide block is installed in the slide groove; the hinge seat is installed on the window frame, and the hinge is installed on the window sash. The utility model can control the opening and closing angle of the window sash through the cooperation of the slide block and the limit slot, thereby enhancing the safety of the window under abnormal weather conditions.

Description

A limitable window hinge

Technical field:

The utility model relates to a door and window accessory, in particular to a position-limitable window hinge.

Background technique:

Most of the existing steel windows or aluminum alloy windows are a single mandrel and bushing structure. This structure can only connect and fix the sash on the window frame, so that the sash can rotate around the mandrel of the hinge, and the sash cannot be rotated around the hinge. position. For the window that sash is outwardly opened, when a strong wind blows suddenly, because the sash cannot be positioned, sometimes the sash can be closed with a bang by the strong wind, which brings trouble and unsafe factors to people's lives. In order to position the sash, people usually install a set of sash opening degree adjustment mechanism made up of struts, slideways and fixed nuts, which also brings troubles to people's lives because they need to be installed separately.

Invention content:

The purpose of the utility model is to provide a position-limitable window hinge, which is used to solve the problem that the existing window sash cannot be positioned.

The technical scheme adopted by the utility model to solve the technical problem is: the limitable window hinge consists of a hinge seat, a central shaft, a hinge, a slider, and the rotating body on one side of the hinge is sleeved outside the central shaft and Rotationally connected with the central shaft, the two ends of the hinge seat also have a rotating body, and the two ends of the central shaft respectively extend into the rotating body of the hinge seat and are rotationally connected with the rotating body of the hinge seat; the rotating body of the hinge seat A plurality of limiting grooves are arranged on the hinge, and a slide groove is arranged on the rotating body of the hinge, and the slide block is installed in the slide groove; the hinge seat is installed on the window frame, and the hinge is installed on the window sash.

There are five limit grooves in the above-mentioned scheme.

The utility model has the following beneficial effects:

1. The utility model can control the opening and closing angle of the window sash through the cooperation of the slider and the limit groove, and enhance the safety of the window under abnormal weather conditions.

2. The utility model is flexible in use, can realize window position limitation, and can realize window free rotation, and can be selected and used according to needs.

3. The utility model has a simple structure, is not easy to fall off, and is safe to use.

Detailed ways

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

As shown in Figure 1, this limitable window hinge consists of a hinge seat 1, a central shaft 2, a hinge 3, and a slider 4. The hinge seat 1 is installed on the window frame, and the hinge 3 is installed on the window sash. The central axis 2 connects the hinge seat 1 and the hinge 3 . The rotating body on one side of the hinge 3 is nested outside the central shaft 2 and connected to the central shaft 2 in rotation, the hinge 3 can rotate around the central shaft 2; The ends respectively extend into the rotating body of the hinge seat 1 and are rotatably connected with the rotating body of the hinge seat 1. The hinge seat 1 can also rotate around the central axis 2; the rotating body of the hinge seat 1 is provided with a plurality of limiting Position groove 5, limit groove 5 can be designed as five, and five limit grooves 5 are evenly arranged. The rotating body of the hinge 3 is provided with a chute 6 , the slide block 4 is installed in the chute 6 , and the slide block 4 can slide up and down along the chute 6 . Referring to Figure 1, when the hinge 3 rotates, the chute 6 rotates along the central axis to one of the limiting grooves 5, and corresponds to the limiting groove 5, at this time the slider 4 can partially slide into the limiting groove 5, the hinge 3 is limited here, and then the window sash is limited here.

If the slide block 4 in the utility model moves downward, it is completely in the chute 6, and the window sash can rotate freely. This state is shown in Fig. 2.

Because the damping between the chute 6 and the slide block 4 is relatively large, it must be promoted by hand so that the slide block 4 can slide up and down, and cannot move downwards by its own weight.

Considering the strength problem, the material for making the hinge can be iron or stainless steel.
