Technical Field

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

Background

The sliding support hinge is an important part in door and window hardware and is used for connecting a window sash and a window frame and enabling the window to be opened and closed, the conventional sliding support hinge is provided with switch damping, mainly by arranging a sliding groove and a sliding block, damping is generated by utilizing the friction force between the sliding block and the sliding groove, the friction force between the sliding block and the sliding groove is reduced along with the increase of the switching times, the direction of the force generated during window opening and closing is inconsistent with the sliding direction of the sliding block, on one hand, the friction force between the sliding block and the sliding groove is not uniform in the opening and closing process, the opening and closing force required in different angles in the window opening and closing process is inconsistent, on the other hand, the sliding block can be pulled to the sliding groove in a certain lateral direction, and the sliding groove is pulled to deform and falls off.

the utility model aims to provide a sliding support hinge which does not need to be provided with a traditional sliding chute and a sliding block to generate damping, the damping force is more linear in the opening and closing process of a window sash, the friction is reduced under the condition of ensuring the damping force, the function of adjusting the damping force is added, the opening and closing process of the window sash is stable and smooth, and the durability can be improved.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a sliding support hinge comprises a window frame fixing piece, a window sash fixing piece, a damping external member, a supporting piece and a cantilever, wherein the damping external member comprises a piston and a sleeve, a first hinge point is arranged between one end of the supporting piece and the window frame fixing piece, a second hinge point is arranged between the other end of the supporting piece and the window sash fixing piece, a third hinge point is arranged between the window sash fixing piece and one end of the cantilever, a fourth hinge point is arranged between the other end of the cantilever and the window frame fixing piece, a fifth hinge point is arranged between the piston of the damping external member and the first hinge point and the fourth hinge point on the window frame fixing piece, and a sixth hinge point is arranged between the sleeve of the damping external member and the supporting piece; when the sliding support hinge is vertically arranged at the top of the side edge of the window sash, the switch of the window sash drives the window sash connecting sheet to perform rotary offset motion, the window sash connecting sheet also drives the supporting sheet to perform rotary motion around the first hinge point and the cantilever around the fourth hinge point simultaneously when moving, the supporting sheet also drives the damping sleeve to perform rotary motion around the fifth hinge point simultaneously when performing rotary motion around the first hinge point, and when the damping sleeve performs rotary motion around the fifth hinge point, the distance between the fifth hinge point and the sixth hinge point is increased or decreased in the motion process, and at the moment, the piston and the sleeve in the damping sleeve perform reciprocating piston motion along with the switch of the window sash.

The further measures taken are: the piston and the sleeve are arranged in the damping sleeve, when the piston moves in the sleeve in a reciprocating mode, acting force for blocking movement exists between the piston and the sleeve, and the acting force is damping when the sliding support hinge moves.

Specifically, the piston and the sleeve are arranged in the damping sleeve, the outer size of the piston is consistent with the inner size of the sleeve, and certain friction force exists between the outer surface of the piston and the inner wall of the sleeve during movement; the piston is made of a magnet, the sleeve is made of copper, and a certain magnetic field resistance is generated when the magnet and the copper move mutually; a screw hole is formed in the top of the sleeve, an air hole screw which is used for adjusting the air inlet and outlet speed in the sleeve is assembled on the screw hole, the tighter the air hole screw is screwed, the greater the air resistance in the sleeve is, the greater the generated damping is, and therefore the purpose of adjusting the damping size is achieved.

Such a design has the advantage that:

1. the production of the damping of the sliding support hinge is generated by changing the lateral push-pull through the sliding block into a centrifugal or centripetal push-pull piston type, the damping force is more linear, the risk that the sliding block pulls the sliding groove to deform is reduced, and the use smoothness and the durability of the sliding support hinge are improved.

2. The manufacturing material of piston is magnet, and telescopic manufacturing material is copper, can produce certain magnetic field resistance when the motion between magnet and the copper, under the same circumstances of sliding support hinge overall damping dynamics, can reduce the frictional force between partial piston and the sleeve, has further promoted the durability of sliding support hinge.

3. A screw hole is seted up at the sleeve top, and is equipped with the gas pocket screw that is used for adjusting air in-out speed in the sleeve on the screw hole, and the air resistance between piston and the sleeve can further reduce the frictional force between partial piston and the sleeve on the one hand, has further promoted the durability of sliding support hinge, and the air resistance size between on the other hand piston and the sleeve is adjustable, has promoted the sliding support hinge easy-to-use nature.
