Abstract

The utility model provides a cabinet door cushioning hinge for furniture, comprising a gland bush, a movable hinge arm, an annular gear and a fixed hinge arm. The annular gear is arranged on the gear shaft of the gland bush. The cover plate of the gland bush, the ring of the movable hinge arm and the disk of the fixed hinge arm have the same external diameter, the inner diameter of the ring is a little larger than the sum of the height of the annular gear and the length of tooth. The gear teeth of the annular gear is zigzag and three to five gear teeth matched with the annular gear are arranged on the inner circle of the joint of the ring and the hinge arm. A screw is connected with a threaded hole on the disk of the fixed hinge arm after passing through a central hole on the gland bush, and the gland bush, the waveform plastic washer, the ring of the movable hinge arm, plastic washer and the disk of the fixed hinge arm are connected together by the screw. The annular gear is fixed in the centre by the gland bush and the disk at a degree of compacting. The utility model adopts the frictional resistance caused by the movable hinge and the annular gear meshing rotating to achieve cushioning, and can be used in the cabinets with a turn-downwards door, such as wall cupboard.

Description

Furniture cushions hinge with the cabinet door

Affiliated technical field

The utility model step and furniture part, particularly a kind of furniture cushions hinge with the cabinet door.

Background technology

In furniture, there is the cabinet door of some cabinets that are arranged at the higher position to open from top to bottom, to be convenient for people to use.Yet in prior art, its cabinet door just is articulated on the cabinet with two common hinges, therefore do not notice slightly in use that the cabinet door in down upset rapidly under the effect of gravity bigger impact sound takes place, sometimes also can injure human body, this is the deficiency of prior art just.

Summary of the invention

The purpose of this utility model is to provide a kind of cushioning effect that rises, and avoids the cabinet door to overturn downwards and produces the furniture that collides cabinet door buffering hinge.

Task of the present utility model realizes by this way: this cabinet door buffering hinge is by fixing pivoted arm, movable pivoted arm, ring gear, gland, plastic washer and corrugated plastic packing ring are formed, fixedly pivoted arm is linked by a disk and a pivoted arm, gland is formed by connecting by a cover plate and a rooted tooth wheel shaft, front end at gear shaft has three location plush coppers, have three blind holes that cooperate with the location plush copper in the fixing disc centre of pivoted arm, the gear teeth of ring gear are zigzag, be installed on the gear shaft, movable pivoted arm is made of an annulus and a pivoted arm that links with it, the internal diameter of annulus is a bit larger tham the ring gear external diameter and adds a tooth depth sum, and with the interior ring of the annulus of pivoted arm junction on be provided with 3～5 gear teeth that cooperate with ring gear, screw passes the centre bore of gland and is connected gland with the fixing screwed hole of pivoted arm disc centre, the corrugated plastic packing ring, the annulus plastic washer of movable pivoted arm and fixedly the disk of pivoted arm link together, and by the gland inner face with in the middle of fixedly pivoted arm disk inner face is pressed on ring gear, the cover plate of gland, the annulus of movable pivoted arm and fixedly the external diameter of the disk of pivoted arm equate.

The purpose of this utility model also can take following measure to realize:

Be provided with a spacing square groove of concentric semicircle at the fixing disk inward flange of pivoted arm, on correspondence position on the annulus of movable pivoted arm, be provided with a slide block that cooperates with spacing square groove, make the rotational angle of hinges be not more than 180 °.

Described corrugated plastic packing ring is arranged in the circular groove of gland cover plate.

Fixedly pivoted arm, movable pivoted arm and gland are all with the engineering plastics injection mo(u)lding of aluminium alloy compression casting moulding ring gear.

For reducing gland and the fixedly wearing and tearing of pivoted arm disk and ring gear, between gland and the ring gear and fixedly respectively be provided with an annular steel disc between pivoted arm disk and the ring gear, last annular steel disc decided the longitudinal register groove with three on three plush coppers on its endoporus and the gear shaft and cooperated on the fixed gear shaft, and back a slice annular steel disc is located plush coppers with triangle endoporus and gear shaft three and cooperated and be fixed on the gear shaft.

The utility model is to use like this: fixedly the pivoted arm of pivoted arm is installed on the cabinet wall by its pilot hole with screw, and the pivoted arm of movable pivoted arm is installed on the cabinet door.When people need open the cabinet door, at manpower and cabinet door under the effect of gravity, saw shape tooth on the movable pivoted arm annulus can embed on the saw shape tooth of ring gear, because both teeth directionals are opposite, the annulus of its movable pivoted arm also rotates thereupon when the cabinet door overturns downwards, just drives ring gear by being meshing with each other of sawtooth and rotates.Because ring gear and gland and fixedly cooperating between the disk of pivoted arm be resilient tight fit, its mutual frictional force must become the resistance of rotation, the upset of cabinet door must could realized under certain manpower effect, thereby avoided the generation of clashing into.When people need close the cabinet door, be that the cabinet door overturns from bottom to top, because movable pivoted arm is under the self-gravity action of cabinet door, movable pivoted arm can move down a little, saw shape tooth on its annulus just breaks away from ring gear, and be that both saw shape tooth rotates along the back of tooth when rotating, can not drive ring gear to rotate, make the up upset very like a cork of cabinet door.

From structure of the present utility model and operating principle as can be seen, the utility model can solve when existing cabinet door down overturns effectively can produce the problem of collision, but also has safe and reliable advantage.
