Description

a hinge

technical field

The utility model relates to the technical field of door and window hardware accessories, in particular to a hinge.

Background technique

Hinges are a kind of commonly used door and window hardware accessories, mostly made of stainless steel. Its main function is to install doors and windows on the door and window frames. Of course, in practice, hinges are generally used for window installation and less for door installation.

Existing hinges generally include slide rails, sliders and a connecting mechanism, wherein the rails are fixed on the window frame by fasteners, and the sliders are slidably arranged on the slide rails and are located in the slide grooves provided on the slide rails. The bottom surface has an active area for sliding the slider and a fixed area for installing fasteners. The connecting mechanism connects the rod slider and is installed on the slide rail, and the connecting rods are riveted to each other to form four or more rods. The rod mechanism is used to realize the installation of doors and windows and to support the opening and closing of doors and windows. Although the structure of the hinge can achieve the above functions, the main weight of the door and window is finally transmitted to the connecting part of the connecting rod and the slider and to the chute. In practice, since the connecting rod and the slider are connected by rivets, and the chute is The material is made of stainless steel sheet metal with a relatively thin thickness. Since the rivet bears the weight of most doors and windows, the connection between the connecting rod and the slider is easily damaged, the slide rail is easily deformed, and even the slider is derailed.

Most of the existing hinges do not have the functions of double self-locking, positioning, and size adjustment of left and right or horizontal four directions, and the installation is relatively inconvenient.

SUMMARY OF THE INVENTION

The content of the utility model is to provide a hinge, which aims to solve the functions of the existing hinges being unreasonable in force, easily deformed by the chute, and unable to adjust the positioning and the position of the window sash.

The utility model proposes a hinge, which is used to be installed on the door and window sash and the door and window frame, including a stainless steel precision casting that is worn in the groove of the door and window sash, a stainless steel precision casting stuck in the door and window frame, a first support rod, a second Two support rods, long connecting rods and fasteners with adjustment function. The door and window sash and the door and window frame are all made of aluminum alloy profiles, the profiles are all provided with a groove, and the stainless steel precision castings worn in the door and window sash grooves are provided with protruding edges, and the protruding edges are compatible with the profile grooves. match.

The stainless steel precision castings worn in the door and window sash grooves and the stainless steel precision castings stuck in the door and window frames are both precision casting processes and are integrally formed. The stainless steel precision castings worn in the door and window sash grooves Castings and stainless steel precision castings stuck in door and window frames are L-shaped designs.

The horizontal part of the stainless steel precision casting stuck in the door and window frame is installed on the groove of the window frame, the bottom of the horizontal part is designed with a protrusion, which can be easily embedded in the groove of the window frame profile, and the vertical part has a positioning function and can pass fasteners. Fixed function, with double self-locking notches at horizontal and vertical corners.

The horizontal part of the stainless steel precision casting in the groove of the window sash is inserted into the groove of the window sash, and the vertical part is designed with an adjusting screw with a bayonet to connect with the aluminum transmission rod that penetrates into the groove of the sash profile. The window sash is moved horizontally as a whole, and the stainless steel precision castings worn in the door and window sash grooves are provided with double self-locking protrusions at the horizontal and vertical corners. The stainless steel precision castings stuck in the door and window frame are engaged and locked. The horizontal part is designed with an adjustable eccentric round screw cap. By rotating the screw cap, the window sash is driven to press the window frame or move in the opposite direction. The horizontal end is designed with a fastening The stainless steel precision castings and the window sash profiles are fastened through the steel sheets and screws in the window sash.

The first support rod is made of stainless steel sheet metal technology, and one end is riveted to the stainless steel precision casting that is padded with copper gaskets and stuck in the door and window frame. Closed type, the protruding teeth of the first support rod engage with the notch of the end of the second support rod, which is also riveted on the stainless steel precision casting with copper gaskets and clamped in the door and window frame. During the opening process, both ends are closed. The head rotates in the opposite direction at the same time. After the window sash is opened 90 degrees, the raised edge of the first support rod meshes with the notch on the side of the end of the second support rod, which plays a 90-degree positioning function. The other end of the first support rod It is riveted to the end of the stainless steel precision casting which is worn in the groove of the door and window sash, and there is a copper gasket in the middle to reduce the metal friction between the stainless steel parts.

The second support rod is made of stainless steel sheet metal technology, and one end is riveted to the stainless steel precision casting that is padded with copper gaskets and stuck in the door and window frame. The notch of the second support rod meshes with the protruding teeth of the end of the first support rod. During the opening process, the two ends rotate in the opposite direction at the same time. After the window sash is opened 90 degrees, the notch of the second support rod and the end of the first support rod The protruding edges on the side of the head are engaged to play a 90-degree positioning function. The other end of the second support rod is riveted in the middle of the long connecting rod, and a copper gasket is arranged in the middle to reduce the metal friction between the stainless steel parts.

The long connecting rod adopts a stainless steel sheet metal process, and one end of the connecting rod is riveted to the middle of the stainless steel precision casting through the groove of the door and window sash, and a copper gasket is arranged in the middle to reduce the metal friction between the stainless steel parts. The middle position is riveted with the second support rod, and there is a copper gasket in the middle to reduce the metal friction between the stainless steel parts. Next to the middle riveting position, there is a bend of the long connecting rod, and then it is horizontally connected to the end of the long connecting rod. , the other end of the long connecting rod is designed with a rotatable riveting sliding block.

The slider at the end of the long connecting rod passes through the long connecting rod, the injection-molded gasket, the injection-molded steel part, and the elliptical steel sheet is finally riveted with the steel sheet to form the sliding block through a screw with a hexagonal nut. As a whole, the slider can be rotated by adjusting the inner hexagon, so that the plastic-clad steel parts and the elliptical steel sheets are embedded in the notch of the door and window frame profiles, and then rotated again to make the positioning line of the slider nut and the reserved positioning line on the long connecting rod. Aligned, the slider can move horizontally and straightly in the groove of the profile of the door and window frame, and at the same time can not come out of the groove of the profile, which plays the role of sharing the self-weight of the window sash to the window frame.

The beneficial effects of the utility model are as follows: the hinge proposed by the utility model aims to solve the functions of the existing hinge with unreasonable force, easy deformation of the chute, unadjustable positioning and the position of the window sash.
