Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a gasket with adjustable thickness. Background Art

[0002] A gasket is a material made of paper, rubber or copper sheet, placed between two planes to strengthen the seal. It is a sealing element set between static sealing surfaces to prevent fluid leakage. Existing gaskets generally cannot adjust their thickness after being manufactured and formed, so their applicability is single and their thickness cannot be changed according to usage requirements. In addition, existing gaskets are generally devices with high hardness. After being squeezed, they are prone to cracks or even breakage due to the lack of buffering parts, which affects their use.

[0006] The side of the lower gasket is provided with a plurality of slots for facilitating the rotation of the lower gasket.

[0007] The side of the lower gasket is provided with four slots which are evenly distributed with the axis of the gasket below being the axis of rotation; the lower side of the upper gasket is provided with six or more connecting grooves which are evenly distributed with the axis of the gasket below being the axis of rotation.

[0008] The lower gasket is rotated and tightened in a clockwise direction, and the anti-loosening protrusion gradually protrudes upward in a counterclockwise direction.

[0009] There are four anti-loosening protrusions in total, and the four anti-loosening protrusions are evenly distributed and rotated around the axis of the gasket below.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] See Figures 1 to 6 .

[0020] A gasket with adjustable thickness, comprising an upper gasket 1 and a lower gasket 2, and also comprising a buffer pad 3; a threaded connection sleeve 4 coaxial with the upper gasket 1 is connected to the lower middle portion of the upper gasket 1, the buffer pad 3 is sleeved on the threaded connection sleeve 4, and the buffer pad 3 is threadedly connected to the threaded connection sleeve 4 by the lower gasket 2 and the threaded connection sleeve 4 and is limited between the lower gasket 2 and the upper gasket 1; an anti-loosening protrusion 5 is provided on the upper part of the lower gasket 2, specifically, the lower gasket 2 is tightened by rotating it clockwise (refer to Figure 4 、 5 , Figure 4 、 5The middle part is marked with the direction in which the lower gasket 2 is tightened on the threaded connection sleeve 4), and the anti-loosening protrusion 5 gradually protrudes upward in the counterclockwise direction. Through this protrusion structure, it is more difficult for the lower gasket 2 to rotate counterclockwise relative to the threaded connection sleeve 4, thereby achieving the anti-loosening effect; specifically, there are four anti-loosening protrusions 5 in total, and the four anti-loosening protrusions 5 are evenly distributed and rotated around the axis of the lower gasket 2 as the axis.

[0021] A connecting groove 7 is provided below the upper gasket 1, and a connecting block 8 corresponding to the connecting groove 7 is connected to the buffer pad 3, and the connecting block 8 is inserted into the connecting groove 7; specifically, more than six connecting grooves 7 are provided below the upper gasket 1, and the axis of the gasket 1 is used as the axis for rotation and are evenly distributed. The utility model inserts the connecting block 8 into the connecting groove 7, so that relative rotation is not likely to occur between the buffer pad 3 and the upper gasket 1, and the installation is more stable.

[0022] The side of the lower gasket 2 is provided with a plurality of slots 6 for facilitating the rotation of the lower gasket 2; specifically, the side of the lower gasket 2 is provided with four slots 6 evenly distributed with the axis of the lower gasket 2 as the axis of rotation; the utility model is convenient for rotating the lower gasket 2 by inserting a metal rod into the slot 6 and rotating the lower gasket 2 by the metal rod (refer to Figure 4 、 5 ).

[0023] The utility model provides a gasket with adjustable thickness. The thickness can be adjusted by rotating the upper gasket 1 or the lower gasket 2 to adjust the distance between the upper gasket 1 and the lower gasket 2, thereby adjusting the thickness of the utility model, and replacing the buffer pad 3 suitable for the distance. The thickness of the buffer pad 3 is selected according to the distance between the upper gasket 1 and the lower gasket 2. During the use of the utility model, when the upper gasket 1 and the lower gasket 2 are squeezed by external force, a certain amount of buffering can be provided by the buffer pad 3, thereby protecting the upper gasket 1 or the lower gasket 2 from being easily damaged.
