Two sections power hydro-cushion hinges

Technical field

The utility model relates to a kind of hinge, in particular for the door hinge of furniture.

Background technology

Furniture industry generally uses hinge to connect the cabinet door when making furniture, and this door is hinged with spring assembly, make to open the door or have a thrust at closing time, has removed the trouble that hinged door hinge in the past needs magnetic or latch to fix from, uses very convenient.Its deficiency is because the screen resilience effect of spring, in that the collision of door and cabinet can take place at closing time, sends sound, even breaks putting bad or breakable article in the cabinet.In order to address this problem; People have invented hydro-cushion hinge, are that 2005200563050 " a kind of hydro-cushion hinge with chain link transmission mechanism ", number of patent application are 2008200429360 and 2009200499033 " hydro-cushion hinge " like number of patent application.It is convenient not enough that these hydro-cushion hinges use, and requires further improvement.

The utility model content

The purpose of the utility model is a kind of hydro-cushion hinge simple in structure of design, and it can overcome the deficiency of prior art.

The utility model is realized through following technical scheme:

A kind of hydro-cushion hinge; Include hinge cup, connecting rod, pivoted arm, shift arm, base, snubber, torsion spring, rocking bar and drive rod; Snubber is installed in the cavity that is made up of base and shift arm, and pivoted arm is loaded on the shift arm through machine silk and adjusting silk braid, and an end of connecting rod passes through axle and hinge glass flexible connection; The other end of connecting rod flexibly connects through axle and pivoted arm

It is characterized in that: rocking bar is the U-shaped gore; Its place, nearly two jiaos of positions has circle center hole and circumferential apertures respectively; With circle center hole opposed U-shaped outer bottom be drive surface, flexibly connect the location through circle center hole and pivoted arm axle, through the tailpiece of the piston rod axle flexible connection of circumferential apertures and snubber; Drive rod is provided with stomidium and mesopore; The other end relative with stomidium is drive division, and mesopore is between stomidium and drive division, and drive rod is movably connected on the pivoted arm through the mesopore axle; The drive surface of the end face that makes drive division on the rocking bar, the other end of drive rod flexibly connects through stomidium and hinge cup axle; Torsion spring compresses pivoted arm and drive rod, makes the hinge cup have to close through connecting rod and drive rod and makes a concerted effort.

The utility model is simple in structure, and dependable performance is used flexibly.

The specific embodiment

Below through embodiment the utility model is described further.

Embodiment

With reference to figure 1, Fig. 2 and Fig. 3; A kind of two sections power hydro-cushion hinges that the utility model proposes; Include hinge cup 1, connecting rod 12, pivoted arm 10, shift arm 8, base 4, snubber 5, torsion spring 11, rocking bar 3 and drive rod 2; Base 4 and shift arm 8 are connected through coupling assembling, and coupling assembling comprises plastics button 6, stage clip 61, plastics button mold insert 62;

Snubber 5 flexibly connects through axle 50 and plastics button mold insert 62, and snubber 5 is positioned at the cavity that is made up of base 4 and shift arm 8, pivoted arm 10 through machine silk 7 with regulate silk 9 and be set on the shift arm 8;

One end of connecting rod 12 flexibly connects through axle 121 and hinge cup 1, and the other end of connecting rod 12 flexibly connects through axle 122 and pivoted arm 10;

Rocking bar 3 is the U-shaped gore; Its place, nearly two jiaos of positions has circle center hole 31 and circumferential apertures 32 respectively; With circle center hole 31 opposed U-shaped outer bottoms be drive surface 33; Rocking bar 3 flexibly connects the location through circle center hole 31 and axle 310 and pivoted arm 10, flexibly connects through circumferential apertures 32 and piston rod 51 ends of axle 320 with snubber 5;

Drive rod 2 is provided with stomidium 22 and mesopore 21; With the stomidium 22 relative other ends be drive division 23; Mesopore 21 is between stomidium 22 and drive division 23; Drive rod 2 is movably connected on the pivoted arm 10 through mesopore 21 and axle 210, the drive surface 33 of the end face that makes drive division 23 on the rocking bar 3, and the other end of drive rod 2 flexibly connects through stomidium 22 and axle 220 and hinge cup 1;

Torsion spring 11 is set on connecting rod 12 and the connecting axle 122 that pivoted arm 10 is connected, and torsion spring 11 compresses with pivoted arm 10 with drive rod 2, and torsion spring 11 makes hinge cup 1 have to close through drive rod 2 to make a concerted effort.

In the present embodiment, snubber 5 is a kind of one-way damper.

The usage operation process of present embodiment has down:

Door opening state is as shown in Figure 1;

Torsion spring 11 is made a concerted effort little through the pass that 2 pairs of hinge cups 1 of drive rod apply;

The piston rod 51 of snubber 5 is in the state of stretching out;

Rocking bar 3 is put to the right to maximum angle;

The end face of the drive division 23 of drive rod 2 leaves the drive surface 33 on the rocking bar 3;

By outer force urges at closing time, hinge cup 1 counterclockwise rotates, and the power arm of drive rod 2 is driven, and drive rod 2 rotates around axle 210 clockwise directions, and torsion spring 11 makes a concerted effort to increase gradually through the pass that 2 pairs of hinge cups 1 of drive rod apply;

When hinge cup 1 turned to certain angle (40-50 °), the pass that torsion spring 11 applies through 2 pairs of hinge cups 1 of drive rod makes a concerted effort to increase to did not need outer force urges can close the door automatically yet;

Under the effect of torsion spring 11, to close automatically and make a concerted effort further to increase, drive surface 33 and drive rocker 3 that the end face of the drive division 23 of drive rod 2 touches on the rocking bar 3 are swung left; Rocking bar 3 promotes piston rod 51 and moves inward, and piston rod 51 slowly moves inward under the effect of snubber 5, up to the state of closing the door (like Fig. 2).

This shows that the final stage of closing the door is slowly carried out.

Otherwise, close a state such as Fig. 2 when hinge cup 1 is in, when being opened the door by outer force urges; Hinge cup 1 clockwise direction rotates; The power arm of drive rod 2 is driven, and drive rod 2 counterclockwise rotates around axle 210, and torsion spring 11 reduces through the pass that 2 pairs of hinge cups 1 of drive rod apply with joint efforts gradually;

The end face of the drive division 23 of drive rod 2 leaves the drive surface 33 on the rocking bar 3, and piston rod 51 is shot out and promoted rocking bar 3 and swings to maximum angle (like Fig. 1) to the right under the effect of snubber 5 inner springs;

When opening the door certain angle, torsion spring 11 is not made a concerted effort to be reduced to and can be closed the door automatically through the pass that 2 pairs of hinge cups 1 of drive rod apply; At this moment door can rest on more any position (like Fig. 1) in the scope of wide-angle (40-110 °).
