Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described.

First embodiment

See Fig. 1-Fig. 5, this hinge for furniture, comprise the flexible cup base 1 that connected by articulated jib 2 and regulate cover plate 6, articulated jib 2 one end is hinged by bearing pin and flexible cup base 1, the other end by eccentric nail with regulate that cover plate 6 is adjustable to be connected.

Be provided with in hinge at least to produce flexible cup base 1 and open and close the torsion spring 4 of active force, torsion spring 4 is arranged on the cup of flexible cup base 1, and comprises the first feet 4.1 and be connected with articulated jib 2, and the second feet 4.2 is connected with flexible cup base 1; Corresponding first feet 4.1 of described articulated jib 2 arranges at least one section of cambered surface 2.2 and is connected, first feet 4.1 is also provided with working of plastics 5, working of plastics 5 is connected in hinge opening-closing process with the cambered surface 2.2 of articulated jib 2, and described working of plastics 5 is opening shell-like.

Also be provided with the Automatic-reset hydraulic damper 3 playing cushioning effect in hinge closing process in flexible cup base 1, articulated jib 2 is at least connected when hinge is closed with Automatic-reset hydraulic damper 3; Described articulated jib 2 closes work plane or/and Automatic-reset hydraulic damper 3 is provided with hinge.

Above-mentioned Automatic-reset hydraulic damper 3 comprises cylinder body 3.1 and piston rod 3.2; Be provided with slot 1.1 in the cup of flexible cup base 1, cylinder body 3.1 is arranged on slot 1.1 by damper cover 7; Be provided with damping element (failing in figure to show) in cylinder body 3.1, piston rod 3.2 one end connects damping element, and the other end stretches out cylinder body 3.1 and connects with flexible cup base 1 inwall; The other end of cylinder body 3.1 is provided with hinge and closes work plane A, and the corresponding hinge of articulated jib 2 is closed work plane A and is provided with contact site 2.1, and contact site 2.1 and hinge are closed work plane A and at least contacted when hinge is closed.

The hinge of cylinder body 3.1 is closed work plane A and is overlooked in plane, and as shown in Figure 6, work plane A closed by contact site 2.1 and hinge is that face contacts when hinge is closed;

Or the hinge of cylinder body 3.1 is closed work plane A and is overlooked V-shaped, and as shown in Figure 7, Figure 8, work plane A closed by contact site 2.1 and hinge is linear contact lay when hinge is closed.

The stationarity when technical scheme that work plane A closed by above two kinds of hinges can ensure that hinge is closed.

See Fig. 9-Figure 11, the stressing conditions of hinge of the present invention in closing process: when hinge is closed, the hinge of articulated jib 2 pairs of cylinder bodies 3.1 is closed work plane A and is produced the vertical and F level of F respectively; Wherein F vertically becomes the frictional force of damper 3, F level is touched damper 3 and is shunk, cause hinge to be closed, be namely made up of the angle acting on the component F level and hinge closedown work plane A that work plane A closed by hinge with the power F closing hinge, the horizontal cosX of formula F=F.

In the horizontal cosX of formula F=F, under acting on the poor situation of power F of hinge closedown work plane A, as long as X angle is constant, power F for closing hinge would not change, hinge is closed and is reached at the uniform velocity, as long as then change the contact angle X that work plane A closed by contact site 2.1 and hinge in hinge closing process at any time, the at the uniform velocity closedown of door body just can be realized.In like manner, as long as angle X slowly increases progressively or slowly reduces, door body thereupon even acceleration is closed or even deceleration closedown.

See Figure 12, Figure 13, the Another Application of articulated jib, difference is that articulated jib 2 is formed in one with regulating cover plate 6.

See Figure 14, hinge is closed work plane A and is made up of a plane and one section of spill cambered surface, when hinge is closed, contact site 2.1 and the hinge of articulated jib 2 are closed work plane A and are contacted, along with hinge is closed, contact site 2.1 acts on hinge and closes the useful component of work plane A because the curvature difference of work plane A closed by hinge, causes the active force for closing hinge substantially to remain unchanged, thus realizes the at the uniform velocity closedown of door body.

Second embodiment

See Figure 15, this hinge for furniture, the hinge of cylinder body 3.1 is closed work plane A and is connected and composed by multiple plane.

3rd embodiment

See Figure 16, this hinge for furniture, the hinge of cylinder body 3.1 is closed work plane A and is made up of one section of spill cambered surface.

4th embodiment

See Figure 17, this hinge for furniture, the hinge of cylinder body 3.1 is closed work plane A and is connected and composed by one section of spill cambered surface and one section of convex-shaped arc surface.

Above-mentioned is preferred version of the present invention, and those of ordinary skill in the art, to its simple modification or transformation, all drop within protection scope of the present invention.
