Embodiment 1

[0032] See Figure 1-Figure 5As shown, a variable resistance damper of the present invention is applied in a toilet, so that it is used to realize the falling and opening of the toilet cover. The variable resistance damper includes a rotating shaft 6 , a housing 1 , a piston 5 , a one-way valve 4 and a spring 2 . The casing 1 is a cylindrical structure with one end closed, and the piston 5 is set in the casing so that it can move along the axial direction of the casing 1, and cooperates with the third sealing ring 54 set on the piston to separate the casing into two inner and outer oil chambers 11, 12. The piston 5 is provided with a through hole 51 for inserting the rotating shaft 6 and a plurality of first oil holes 52 for communicating with the two oil chambers 11, 12, and the through hole 51 is located at the center of the piston 5, and the plurality of first oil holes 52 An oil hole 52 is distributed around the circumference of the through hole 51 . The one-way valve 4...

Embodiment 2

[0040] See Figure 11 , 12 As shown, a variable resistance damper of the present invention differs from Embodiment 1 in that the circumferential dimensions of the inner end surfaces 626 of the respective second flanges 623 of the second shaft section 62 are respectively equal to those of the piston 5 The interval dimension A between each first flange 53 is such that, in the process of realizing the toilet cover falling or opening in the present invention, its rotating shaft 6 will not realize idling, but when the toilet cover falls, it will directly make it The slope 624 of the second flange and the slope 531 of each first flange 53 of the piston slide relative to each other to push the piston 5 to move inward along the axial direction of the casing 1, and when the toilet cover is opened, the spring 2 Under the action of the piston, the inclined surface 624 of the second flange and the inclined surface 531 of each first flange 53 of the piston slide relative to each other and...

Abstract

The invention discloses a variable resistance damper, which comprises a rotating shaft, a shell, a piston, a one-way valve and a spring. The piston is movably installed in the shell in a sleeving manner, and the one-way valve is positioned in the piston. The rotating shaft is also movably installed in the shell in a sleeving manner. The rotating shaft includes a first shaft section and a second shaft section, a tapered groove is arranged on the shaft wall of the first shaft section along the axial direction of the same, the tapered groove is divided into at least two sequentially connected groove sections along the direction from the outside end to the inside end of the first shaft section, the width and depth of at least two groove sections decrease progressively along the direction from the outside end to the inside end of the first shaft section, the first shaft section sequentially penetrates through a through hole of the piston and the one-way valve, and the tapered groove is movably matched with the through hole of the piston. The spring is positioned between the inner side of the piston and the one sealed end of the shell. Mutually matched spiral structures are respectively arranged at the outside end of the piston and the inside end of the second shaft section. The variable resistance damper realizes easy opening and quick descending of a switching mechanism such as a toilet lid.

Description

technical field [0001] The invention relates to a damper, in particular to a variable resistance damper. Background technique [0002] Dampers are widely used in various devices with opening and closing mechanisms, for example, to realize the slow closing of the piano lid, to realize the slow lowering of the toilet lid, etc., among which the application on the toilet is the most typical. In the traditional toilet, the cover and the seat are connected by a non-damping hinge. The advantage is that the toilet cover can be flipped quickly. The disadvantage is that the cover is easy to collide with the seat during the landing process. Noise, not only noise pollution, but also easy to wear and tear the toilet. In order to solve this problem, a hinge with buffering force, that is, a damper, is generally used to connect the cover plate and the seat body of the toilet, so that the cover plate of the toilet can be slowly lowered when it falls. However, the damper used in the prior a...
