Abstract

The utility model relates to a hydraulic buffering hinge with a chain link transmission mechanism, which is mainly composed of a door case, a connecting rod, a connecting block, a chain link with two holes, a chain link with three holes, a buffer, a supporting seat, a connecting seat, an intermediate connecting seat, a locking fastener, a screw spring, a torsion spring, etc. Because two chain links are used for transmission between the connecting block and a piston rod, a buffering force arm is converted from a straight arm into a crank arm, the length between the connecting block and the piston rod is shortened, the required swing space of the connecting block is reduced and thus the integral size of a hinge is reduced. The utility model has the advantages of small size, low cost, convenient and quick installation and debugging, etc., and the integral size of the utility model is identical with a common hinge without a hydraulic buffering function.

Description

A kind of hydro-cushion hinge with chain link transmission mechanism

Technical field:

The utility model relates to a kind of hydro-cushion hinge with chain link transmission mechanism.

Background technology:

Hydro-cushion hinge is a kind of hinge with good buffering effect, and the collision in the time of avoiding the door leaf switch well reaches the purpose of protecting object, reducing noise, and utility model patent 03247692.2 " hydro-cushion hinge " is exactly the initiative of this technology.But above-mentioned patent has the following disadvantages: damper volume wherein is bigger, and the coupling part of contiguous block and piston rod is longer, and the volume that cushions hinge integral body is big, manufacturing cost is higher thereby cause.

Summary of the invention:

The purpose of this utility model provides a kind of hydro-cushion hinge with chain link transmission mechanism, and it can overcome the deficiencies in the prior art.

The utility model is achieved in that it is mainly by the door box, connecting rod, contiguous block, two pore chains joint, three pore chains joint, snubber, bearing, Connection Block, middle Connection Block, tight locking button, helical spring, parts such as torsionspring are formed, wherein, one end of connecting rod is hinged with the door box, the other end and Connection Block are hinged, hinged place at connecting rod and Connection Block is provided with torsionspring, contiguous block is provided with three hinge holes, wherein interstitial hole and Connection Block are hinged, two holes are hinged with the hole that door box and two pore chains save respectively in addition, the interstitial hole of another Kong Yusan pore chain joint of two pore chains joint is hinged, two holes in addition of three pore chains joints respectively with Connection Block and snubber on piston rod hinged, an end and Connection Block away from piston rod on the snubber are hinged, middle Connection Block is enclosed between snubber and the Connection Block, and middle Connection Block and tight locking button combination are buckled on the bearing.

The utility model adopts two chain link transmissions between contiguous block and piston rod, the buffering arm of force is transformed to by straight-arm and cranks arm, shortened the length between contiguous block and the piston rod, reduce the required space of contiguous block swing, thereby dwindled the volume of hinge integral body, compared with prior art, it is less to have volume, cumulative volume and advantages such as the common hinge with the hydraulic cushion function is not identical, and manufacturing cost is lower, and Installation and Debugging are convenient and swift.

Description of drawings:

Fig. 1 is the structural representation of the utility model when being in door opening state

Fig. 2 is that the utility model is in the structural representation when closing state

The specific embodiment:

As Fig. 1, shown in 2, the utility model is mainly by door box 1, connecting rod 2, contiguous block 3, two pore chains joint 4, three pore chains joint 5, snubber 6, bearing 7, Connection Block 8, middle Connection Block 9, tight locking button 10, helical spring 11, torsionspring 12 parts such as grade are formed, wherein, one end of connecting rod 2 is hinged with door box 1, the other end and Connection Block 8 are hinged, hinged place at connecting rod 2 and Connection Block 8 is provided with torsionspring 12, contiguous block 3 is provided with three hinge holes, wherein interstitial hole and Connection Block 8 are hinged, two holes are hinged with the hole that door box 1 and two pore chains save on 4 respectively in addition, the interstitial hole of another Kong Yusan pore chain joint 5 of two pore chains joint 4 is hinged, two holes in addition of three pore chains joint 5 respectively with Connection Block 8 and snubber 6 on piston rod 61 hinged, an end and Connection Block 8 away from piston rod 61 on the snubber 6 are hinged, middle Connection Block 9 is enclosed between snubber 6 and the Connection Block 8, and middle Connection Block 9 is buckled on the bearing 7 with tight locking button 10 combinations.In said structure, door box 1, connecting rod 2, contiguous block 3 and Connection Block 8 constitute a quadric chain, and contiguous block 3, two pore chains joint, 4 and three pore chains joint 5 constitute a chain link transmission mechanism.

In the present embodiment, snubber 6 is a kind of snubbers with one-way valve structures.

When the utility model is in door opening state (as Fig. 1) and is promoted at closing time by external force, under the effect of torsionspring 12, by quadric chain torsion spring power is passed to the chain link transmission mechanism, the piston rod 61 of

pulling snubber

6,6 cushioning effects of snubber, thereby door leaf is closed with slow speed, play the effect of protection and noise abatement;

When being in, the utility model closes a state (as Fig. 2) and when being opened the door by external force pulling, under the effect of external force, by four jointed gear units pulling chain link transmission mechanism, the chain link transmission mechanism promotes the piston rod 61 of snubber 6, the one-way valve opens of establishing in the snubber 6, piston rod 61 is moved under the situation of flowed friction not having, reach the effect of opening the door fast.
