Technical Field

The invention relates to the technical field of building hardware accessories, in particular to a novel hidden bearing hinge.

Background

In daily window use, the hinge is used for connecting a window frame and a window sash, the window sash is manually closed, but the market requirement cannot be met along with the continuous change of the market. Hidden hinge has appeared in the existing market, compares hidden hinge and has the characteristics that improve the outward appearance and improve product grade with ordinary hinge. The existing invisible hinge is generally arranged at the lower side of the window sash so as to achieve the effect of bearing and supporting. In the existing hidden hinge, the height difference between the window sash connecting piece and the window frame connecting piece is large, and meanwhile, a large hanging height is left between the window sash connecting piece and the window frame connecting piece, so that the bearing effect of the hinge is not improved.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a novel bearing hidden hinge which is novel and reliable in structure, strong in bearing capacity, low in noise and small in abrasion.

In order to achieve the above purpose, the invention adopts the technical scheme that: the utility model provides a novel hidden hinge of bearing, includes window frame connecting piece, casement connecting piece and connect in link assembly between window frame connecting piece and the casement connecting piece, the casement connecting piece rotates and is connected with the rolling member, window frame connecting piece upper surface is provided with the blotter, when the hinge closure rolling contact between rolling member and the blotter.

The invention has the beneficial effects that: according to the novel bearing hidden hinge, the buffer pads and the rolling pieces are arranged between the window sash connecting piece and the window frame connecting piece, and the rolling pieces are in rolling contact with the buffer pads in the hinge closing process, so that the friction between the rolling pieces and the buffer pads can be effectively reduced, and the abrasion and the noise are reduced. When the hinge is closed, the window sash connecting piece and the window frame connecting piece are supported by the cushion pad and the rolling piece, so that the bearing capacity of the hinge is improved.

Preferably, the window sash connecting member is formed with a groove recessed toward a bottom surface, and the rolling member is rotatably coupled in the groove. The rolling piece can avoid the window sash by utilizing the groove, and the window sash is prevented from contacting with the rolling piece, so that the rolling piece can roll smoothly.

Preferably, guide slopes for guiding the rolling members are formed at both sides of the buffer pad. Because the cushion pad protrudes out of the upper surface of the window frame connecting piece slightly, the rolling piece can be guided to climb and roll onto the cushion pad by utilizing the guide inclined plane, and the resistance of the hinge when being closed is reduced.

Preferably, the cushion pad is a nylon plastic pad.

Preferably, the connecting rod assembly comprises a first connecting rod, a second connecting rod, a third connecting rod and a rotating block, the rotating block is rotatably connected to the window frame connecting piece and is pivoted with the first connecting rod, the other end of the first connecting rod is pivoted with the window sash connecting piece, the second connecting rod is pivoted with the third connecting rod, the other end of the second connecting rod is pivoted with the window frame connecting piece, and the other end of the third connecting rod is pivoted with the window sash connecting piece. The utilization of the linkage can effectively increase the bearing capacity while limiting the opening angle of the hinge.

Detailed Description

The claimed invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, the novel load-bearing hidden hinge in the present embodiment includes a frame connector 1, a sash connector 2, and a connecting rod assembly connected between the frame connector 1 and the sash connector 2. In this embodiment, the link assembly includes a first link 31, a second link 32, a third link 33 and a rotating block 34, the rotating block 34 is rotatably connected to the window frame connector 1 and is pivotally connected to the first link 31, the other end of the first link 31 is pivotally connected to the window sash connector 2, the second link 32 is pivotally connected to the third link 33, the other end of the second link 32 is pivotally connected to the window frame connector 1, and the other end of the third link 33 is pivotally connected to the window sash connector 2.

Since the assembly is disposed between the frame connector 1 and the sash connector 2, there is a large height difference between the frame connector 1 and the sash connector 2, and since the lengths of the first, second, and third links 31, 32, and 33 are not equal to the lengths of the frame connector 1 and the sash connector 2, the opening angle is too large. Thus in this embodiment a large free space is left between the frame connector 1 and the sash connector 2 when the hinge is closed, where the lack of support could easily cause deformation of the sash connector 2. In this embodiment the sash connection member 2 is thus pivotally connected to a roller member 21, and the frame connection member 1 is provided with a cushioning pad 11 on its upper surface. Specifically, in the embodiment, the rolling member 21 is a copper spindle sleeve, and the cushion pad 11 is a nylon plastic pad, and both the materials have wear-resistant characteristics, so that the service life of the cushion pad 11 can be effectively prolonged.

The rolling contact between the rolling member 21 and the cushioning pad 11 when the hinge is closed is effective to reduce friction between the rolling member 21 and the cushioning pad 11 and thereby reduce wear and noise. When the hinge is closed, the window sash connecting member 2 and the window frame connecting member 1 are supported by the cushion pad 11 and the rolling member 21 to improve the load-bearing capacity of the hinge.

In addition, in the present embodiment, the window sash connecting member 2 is formed with a groove 22 recessed toward the bottom surface, and the rolling member 21 is rotatably connected to the groove 22; the rolling member 21 can be moved away from the window sash by the groove 22, and the window sash is prevented from contacting the rolling member 21, so that the rolling member 21 can roll smoothly. Guide slopes 111 for guiding the rolling members 21 are formed at both sides of the cushion pad 11; since the buffer pad 11 protrudes slightly from the upper surface of the window frame connector 1, the guide slope 111 can guide the rolling member 21 to climb and roll onto the buffer pad 11, thereby reducing the resistance when the hinge is closed.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to limit the present invention in any way. Those skilled in the art can make many changes and modifications to the disclosed embodiments, or modify equivalent embodiments to practice the disclosed embodiments, without departing from the scope of the disclosed embodiments. Therefore, equivalent variations made according to the idea of the present invention should be covered within the protection scope of the present invention without departing from the contents of the technical solution of the present invention.
