Disclosure of utility model

The utility model aims to provide a polytetrafluoroethylene gasket for solving the problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a polytetrafluoroethylene gasket, includes first gasket, the sliding tray has been seted up to the one end of first gasket, the sliding block is installed to the inner chamber of sliding tray, spacing post is all installed to the surface of sliding block and the surface of sliding tray inner chamber, the surface mounting of spacing post has the spring, the second gasket is installed on the top of sliding block.

Preferably, the sliding groove is in a cross groove shape.

Preferably, the sliding block is cross-shaped.

Preferably, the number of the sliding grooves and the sliding blocks is four.

Preferably, the number of the springs is a plurality.

Compared with the prior art, the utility model has the beneficial effects that:

1. This polytetrafluoroethylene gasket installs first gasket and second gasket through setting up the spring to install between the machine, when the machine drove the second gasket and remove, because the sliding block is less than the inner chamber of sliding tray, the sliding block can follow the second gasket and remove this moment, reduces wearing and tearing, after removing the completion, can the sliding block automatically drive the second gasket and get back to the normal position under the effect of spring, avoid the second gasket to take place the skew.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "provided," "connected," and the like are to be construed broadly, and may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 3, the polytetrafluoroethylene gasket of this embodiment includes a first gasket 1, a sliding groove 2 is provided at one end of the first gasket 1, a sliding block 201 is installed in an inner cavity of the sliding groove 2, a limit post 202 is installed on both surfaces of the sliding block 201 and the inner cavity of the sliding groove 2, a spring 203 is installed on a surface of the limit post 202, the first gasket 1 and the second gasket 3 are installed between machines through the arrangement of the spring 203, when the machines drive the second gasket 3 to move, the sliding block 201 moves along with the second gasket 3 at this time because the sliding block 201 is smaller than the inner cavity of the sliding groove 2, abrasion is reduced, after the movement is completed, the sliding block 201 automatically drives the second gasket 3 to return to the original position under the action of the spring 203, the second gasket 3 is prevented from shifting, the second gasket 3 is installed at the top end of the sliding block 201, and the second gasket 3 is mainly used in cooperation with the first gasket 1 through the arrangement of the second gasket 3.

Specifically, the sliding groove 2 is in the shape of a cross groove.

Further, the slider 201 has a cross shape.

Further, the number of the sliding grooves 2 and the sliding blocks 201 is four, so that the number of the sliding grooves 2 and the sliding blocks 201 is four, and the vibration and the abrasion caused by mechanical driving can be reduced when the second gasket 3 moves.

Furthermore, the number of the springs 203 is several, and the wear can be reduced by arranging several springs 203.

The application method of the embodiment is as follows: install first gasket 1 and second gasket 3 to install between the machine, when the machine drove second gasket 3 and remove, because slider 201 is less than the inner chamber of sliding tray 2, slider 201 can follow second gasket 3 and remove this moment, reduces wearing and tearing, after removing, can slider 201 automatically drive second gasket 3 and return to the normal position under the effect of spring 203, avoid second gasket 3 to take place the skew.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
