Hinge shear type track erasable window hidden hinge

Abstract

The invention discloses a hinge shear type track erasable window hidden hinge which comprises a sliding groove, a first connecting rod, a second connecting rod, a long rod and a supporting arm. A sliding block is slidably connected to the sliding groove, one end of the long rod is rotationally connected with the sliding groove, the second connecting rod intersects with the first connecting rod, the second connecting rod is supported at the bottom of the first connecting rod, the second connecting rod is rotationally connected with the first connecting rod at the intersection, one end of the second connecting rod is rotationally connected with the sliding block and is slidably connected to the sliding block in the sliding direction of the sliding block, one end of the first connecting rod is rotationally connected with the sliding block, a rotating connecting point is located between the long rod and the second connecting rod, the other end of the first connecting rod is rotationally connected with one end of the supporting arm, the other end of the second connecting rod is rotationally connected with the other end of the long rod, and the second connecting rod and the long rod arerotationally connected with the middle portion of the supporting arm and are slidably connected to the supporting arm in the length direction of the supporting arm. The hinge structure is simple, opening is smooth and free, return is accurate, and a better bearing effect is achieved.

Description

【Technical field】 [0001] The invention relates to a scissors track wipeable window concealed hinge. 【Background technique】 [0002] In the past door and window wipeable window hidden hinge hardware accessories, most of them used a parallelogram sliding track. When the hinge was initially opened, there was a virtual position. It is called the sash fixing plate. It is used to connect the bracket arm and the slider. The stress on some of the connecting rods is too concentrated, which will easily cause the deformation of the connecting rod and the wear of the related rivets connected to it. Most of the tracks are single-track slideways. When the sash is installed on the window frame, the upper and lower sides need to be connected by hinges. When the hinge is down, the force is normal, but when it is above the sash, the reverse force is not normally caused. The hinge slider is tilted and the sash sags. , Reduce the performance of the sash and the life of the hinge. Especially a...

When the hinge is down, the force is normal, but when it is above the sash, the reverse force is not normally caused. The hinge slider is tilted and the sash sags. , reducing sash performance and hinge life

Especially with the upgrading of window sash performance, its weight is getting bigger and bigger, and the hinges of the existing structure can't meet the demand more and more
