The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

First embodiment

Referring to Fig. 1-Fig. 5, this furniture hinge comprises the movable cup 1 that connects by articulated jib 2 and regulates cover plate 6 that articulated jib 2 one ends are hinged by bearing pin and movable cup 1, and the other end is by eccentric nail and adjusting 6 adjustable connections of cover plate.

Be provided with in the hinge at least movable cup 1 is produced the torsion spring 4 that opens and closes active force, torsion spring 4 is arranged on the cup of movable cup 1, and comprises that first feet 4.1 is connected with articulated jib 2, and second feet 4.2 is connected with movable cup 1; Described articulated jib 2 corresponding first feets 4.1 arrange at least one section cambered surface 2.2 and are connected, also be provided with working of plastics 5 on first feet 4.1, working of plastics 5 is connected in the hinge opening-closing process with the cambered surface 2.2 of articulated jib 2, and described working of plastics 5 is the opening shell-like.

Also be provided with at hinge in the movable cup 1 and close the formula that the automatically resets hydraulic damper 3 that plays cushioning effect in the closed procedure, articulated jib 2 is connected when hinge is closed at least with the formula hydraulic damper 3 that automatically resets; Described articulated jib 2 is closed work plane or/and the formula hydraulic damper 3 that automatically resets is provided with hinge.

The above-mentioned formula hydraulic damper 3 that automatically resets comprises cylinder body 3.1 and piston rod 3.2; Be provided with groove position 1.1 in the cup of movable cup 1, cylinder body 3.1 is arranged on the groove position 1.1 by damper cover 7; Be provided with damping element (failing among the figure to show) in the cylinder body 3.1, piston rod 3.2 1 ends connect damping element, and the other end stretches out cylinder body 3.1 and joins with movable cup 1 inwall; The other end of cylinder body 3.1 is provided with hinge and closes work plane A, and articulated jib 2 corresponding hinges are closed work plane A and are provided with contact site 2.1, and contact site 2.1 is closed work plane A with hinge and contacted when hinge is closed at least.

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

Perhaps, the hinge of cylinder body 3.1 is closed work plane A and is overlooked V-shapedly, and as Fig. 7, shown in Figure 8, it is that line contacts when hinge is closed that contact site 2.1 is closed work plane A with hinge.

More than the stationarity of two kinds of hinges technical scheme of closing work plane A can both guarantee that hinge is closed the time.

Referring to Fig. 9-Figure 11, the stressing conditions of the utility model hinge in closing closed procedure: when hinge was closed, the hinge of 2 pairs of cylinder bodies 3.1 of articulated jib was 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, the F level is touched damper 3 and is shunk, cause hinge to be closed, namely hinge is closed the component F level of work plane A and angle that hinge is closed work plane A constitutes the horizontal cosX of formula F=F by acting on the power F that closes hinge.

Among the horizontal cosX of formula F=F, acting on hinge closes under the poor situation of power F of work plane A, as long as the X angle is constant, just can not change for the power F that closes hinge, hinge is closed and is reached at the uniform velocity, then as long as in hinge closes closed procedure, change the contact angle X that contact site 2.1 and hinge are closed work plane A at any time, just can realize at the uniform velocity closing of a body.In like manner, as long as angle X slowly increases progressively or slowly reduces, the door body is even thereupon to accelerate to close or speed is slowed down and closed.

Referring to Figure 12, Figure 13, the Another Application of articulated jib, difference is that articulated jib 2 and adjusting cover plate 6 are formed in one.

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

Second embodiment

Referring to Figure 15, this furniture hinge, the hinge of cylinder body 3.1 is closed work plane A and is connected and composed by a plurality of planes.

The 3rd embodiment

Referring to Figure 16, this furniture hinge, the hinge of cylinder body 3.1 are closed work plane A and are made of one section spill cambered surface.

The 4th embodiment

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

Above-mentioned is preferred version of the present utility model, and those of ordinary skills all drop within the protection domain of the present utility model its simple modification or transformation.
