Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Referring to Fig. 1, according to one aspect of the present invention, a spring damper is provided, wherein the spring damper includes a housing 1 and a rotating shaft 2 rotatably installed in the housing 1, and the rotating shaft 2 is located in the housing 1 is sleeved with a spring 3, and one end of the spring 3 is fixed to the housing 1, so that the spring 3 can tighten or loosen the rotating shaft 2 when the rotating shaft 2 and the housing 1 rotate relative to each other.

As mentioned above, since the spring damper provided by the present invention includes a housing 1 and a rotating shaft 2 rotatably installed in the housing 1, the rotating shaft 2 is sleeved with a spring 3 at the position inside the housing 1, and the spring 3 One end is fixed to the housing 1 so that the spring 3 can tighten or loosen the rotation shaft 2 when the rotation shaft 2 and the housing 1 rotate relative to each other, so the rotation shaft 2 and the rotation shaft 2 can be tightened by the spring 3 The movement between the shells 1 generates resistance to achieve a damping effect. The spring 3 is used as a damping component, so that the spring damper has a simple structure, convenient maintenance, low maintenance cost, and does not require damping oil.

According to a preferred embodiment of the present invention, one end of the spring 3 can be formed as a spring arm 31 extending radially outward along the rotating shaft 2, and the spring arm 31 and the inner wall surface of the housing 1 are fixed to each other, specifically, the inner wall of the housing 1 A positioning groove can be provided on the inner wall surface, and the spring arm 31 can be plugged and fixed into the positioning groove. Of course, the present invention is not limited thereto, and the spring arm 31 can also be fixed to the housing 1 by other appropriate connection methods.

In addition, the rotating shaft 2 may include a thick column part 21 located inside the housing 1 and a rotating rod part 22 connected to the thick column part 21 and penetrating the housing 1. The maximum cross-sectional area of the rotating rod part 22 is smaller than that of the thick column part 21. Minimum cross-sectional area.

According to another aspect of the present invention, a cover installation structure is also provided, wherein the cover installation structure includes a body 4, a cover 5 and the above-mentioned spring damper, the rotating shaft 2 is installed on the body 4, and the housing 1 is connected to cover plate 5. Wherein, the spring 3 can be set as follows: when the cover plate 5 moves open relative to the body 4, the spring 3 gradually releases the rotating shaft 2, and when the cover plate 5 closes and moves relative to the body 4, the spring 3 gradually tightens the rotating shaft 2. Specifically, it is sufficient to set the winding extension direction of the spring 3 on the rotating shaft 2. Assuming that the spring 3 is winding and extending counterclockwise on the outer peripheral surface of the thick column portion 21 so that the cover plate 5 is opened and moved relative to the body 4, the spring 3. Gradually loosen the rotating shaft 2, then when the spring 3 winds and extends clockwise around the outer peripheral surface of the thick column part 21 so that when the cover plate 5 moves relative to the body 4, the spring 3 gradually tightens the rotating shaft 2. The cover installation structure can be used as the cover installation structure of the washing machine or the cover installation structure of the toilet, thereby preventing the cover 5 from being closed too fast and damaging other components. But the present invention is not limited thereto. On the one hand, the spring 3 is not necessarily set to gradually loosen the rotating shaft 2 when the cover 5 is opened, and gradually tighten the rotating shaft 2 when the cover 5 is closed. Once the user needs to quickly close the cover 5. When slowly opening the cover plate 5, the spring 3 can also be set to gradually tighten the rotating shaft 2 when the cover plate 5 is opened, and gradually loosen the rotating shaft 2 when the cover plate 5 is closed. On the other hand, the cover The plate mounting structure is not limited to being the cover mounting structure of the washing machine or the cover mounting structure of the toilet.

Preferably, a mounting base 6 may be provided on the body 4, and the mounting base 6 has a mounting hole, and the rotating shaft 2 is mounted on the mounting base 6 through the mounting hole.

According to still another aspect of the present invention, there is also provided a washing machine, wherein the washing machine includes the above-mentioned cover plate installation structure, the body 4 can be the main body of the washing machine, and the cover plate 5 can be the upper cover plate 5 of the washing machine, based on the above-mentioned quick damper With many advantages, the overall performance of the washing machine is also improved.

Apparently, the above-mentioned implementation manners are only examples for clear description, rather than limiting the implementation manners. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
