Description

Mute hinge with simple structure

Technical Field

The utility model relates to a connecting piece that furniture was used specifically indicates a silence hinge for furniture.

Background

Hinges are the most common connecting elements in the furniture industry, the main structure of which comprises a hinge arm and is connected with one part of the furniture, and a hinge cup is connected with another part of the furniture, wherein one part of the furniture is a door of the furniture which can move movably, i.e. the hinge movably connects the door of the furniture with the corresponding part of the furniture main body, so that the hinge is in a state of frequently needing to be opened and closed repeatedly. The hinge arm and the hinge cup are movably connected through a pin shaft, and a spring is generally arranged to push the door to be closed by a spring force when the furniture door is closed, an extending end of the spring is contacted with one part of the hinge, when the furniture door is opened or closed, the extending end is pressed by the spring force, and meanwhile, a relative displacement with pressure exists between the extending end and the hinge arm, and the relative displacement can generate intermetallic friction noise. In order to eliminate the above-mentioned friction noise, the prior art is to sleeve a bush made of antifriction material with special-shaped structure on the hinge arm and the hinge cup, and the extending end of the spring contacts with one surface of the bush to reduce the friction noise. The hinge or the noise-reducing hinge described above, in a more specific structure, requires two springs and is disposed outside the recess of the hinge cup, which complicates the structure of the hinge cup, and the bushing described above also requires two corresponding to the two springs, which results in more parts and increases the cost of manufacturing the parts and assembling the hinge, and the special-shaped bushing complicates the mold and increases the manufacturing cost, especially the number of hinges to be manufactured is huge, and the annual market demand reaches several hundred million. Therefore, how to design the hinge with the parts simplified and reasonable as possible under the limited parts and the limited assembly space of the hinge still has a problem to be solved and has great economic value.

Detailed Description

The detailed description of the embodiments of the present invention is given in conjunction with the accompanying drawings of the specification, and it should be noted that the detailed description of the embodiments is provided for the convenience of understanding the technical spirit of the present invention, and should not be construed as limiting the scope of the claims of the present invention.

Referring to fig. 1 to 6, the technical solution of the specific embodiment of the present invention is: including hinge arm 1 and hinge cup 2, the one end of hinge arm 1 is through round pin axle 3 and hinge cup 2 swing joint, and hinge cup 2 has a concave part 4, and above-mentioned technical characteristics are the essential basic structure of hinge, the key is one side in the concave part 4 of hinge cup 2 be equipped with torsional spring 5, stretch out one section 6 of torsional spring 5 and be equipped with the contact of convex part 7 with hinge arm 1 behind a silence mill spare 8, torsional spring 5 cover is located the torsional spring axle 9 that passes above-mentioned concave part 4 and is located one side position of concave part 4. According to the technical scheme, only one torsion spring 5 and one mute grinding piece 8 are needed, the structural members are greatly reduced, the manufacturing cost is greatly reduced, and the mounting process steps and cost of the hinge are also reduced.

The torsion spring shaft 9 is fixedly connected with two side walls of the concave part 4 (not shown in the figure), and the torsion spring 5 is arranged on the torsion spring shaft 9; or a vertical plate 10 is arranged on one side in the concave part 4 of the hinge cup 2, and the torsion spring shaft 9 is positioned on the vertical plate 10 and a side plate of the concave part 4 (shown in figures 1 and 3); in the structure, the torsion spring 5 and the torsion spring shaft 9 are very convenient to install; a damper is arranged in the middle of the concave part 4 for slowing down the speed of the furniture door in the closing process, and the edge of the vertical plate 10 is clamped on one edge of the damper and has a positioning effect on the damper, so that the existing accessories and the complex installation process in the installation of the damper are further reduced, and the preparation cost of the hinge is further reduced.

The silent grinding piece 8 is a kit with a blind hole, the extension section 6 of the torsion spring is inserted into the blind hole, so that the extension section 6 of the torsion spring is not in direct contact with the convex part 7 of the hinge arm 1, and the relative displacement between the extension section 6 of the torsion spring and the convex part 7 does not generate noise caused by metal friction; or the silent grinding member 8 is a collar (shown in fig. 3 and 5) integrally formed at one end of a plate member, the torsion spring shaft 9 passes through the collar, and the plate member is positioned between the torsion spring extension 6 and the convex part 7, and also has the function of silencing.

The convex part 7 is integrally formed on the hinge arm 1 and is positioned above the pin shaft 3, the surface of the convex part 7 is a curved surface or a combination surface of the curved surface and a plane, and the structure is relatively simple (shown in figure 1); or the convex part 7 is an asymmetric cylinder with a through hole and a curved surface, the pin shaft 3 penetrates through the through hole, the convex part 7 and the hinge arm 1 are in a split structure (shown in fig. 6), the convex part 7 is made of metal materials or plastic materials, when the convex part 7 is made of plastic materials, noise generated by friction can be further reduced, and the service life of the mute grinding piece 8 is further ensured. The convex part 7 is integrally formed on the hinge arm 1 and is located at the middle position or the top (not shown) of one side of the hinge arm 1, and has no influence on the manufacturing and manufacturing cost of the hinge arm 1, but because the convex part 7 moves upwards relative to the hinge arm 1, the length of the extension section 6 of the torsion spring needs to be properly increased, the elasticity of the torsion spring 5 is increased, the acting force applied to the hinge arm 1 is increased, and the torsion spring hinge is obviously effective and effective only by being provided with one torsion spring 5.
