In the above technical scheme: the friction ring orientation the slope of the cap body sets up for it is easier when inserting the downthehole of needs installation, and because the deformation of friction ring when taking out, frictional force can increase, avoids under the circumstances of non-initiative, the utility model discloses deviate from in the follow hole.

The utility model discloses a further set up to: and a plurality of reinforcing columns are uniformly arranged between the adjacent friction rings.

In the above technical scheme: the reinforcing columns are used to maintain the shape of the friction ring so that it can maintain its shape without installing a pool.

The utility model discloses a rubber dustproof cap compares with prior art:

1. the utility model can deform the outer wall surface of part of the cap body by pressing through the arrangement of the cavity and the channel in the cap body, thereby generating a position easy to clamp, facilitating the force application of fingers and taking out the utility model; 2. the utility model discloses be provided with the friction ring for the installation is like downthehole back the utility model discloses be difficult for receiving to collide with and deviate from, more firm of installation.

Detailed Description

The embodiments of the present invention will be described in detail below, and this embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1-4, the utility model provides a rubber dustproof cap, including the spliced pole 10 and the cap body 20, the spliced pole 10 is fixed to be set up the one end of the cap body 20, just evenly be provided with a plurality of friction rings 101 on the spliced pole 10, the inside annular cavity 201 that is provided with of the cap body 20, the inside at least two passageways 202 that still evenly is provided with of the cap body 20, just passageway 202 one end with cavity 201 is connected, the other end with the cap body 20 is kept away from a terminal surface intercommunication of spliced pole 10. The cap body 20 is cylindrical, and an arc-shaped chamfer is arranged at the bottom of the cap body 20; the shape of the cavity 201 corresponds to the bottom outside shape of the cap body 20; preferably, the number of the channels 202 is 4, and the cap body 20 and the connecting column 10 are made of rubber.

As shown in fig. 1-4, in the rubber dust cap of the present invention, the side of the channel 202 away from the outer wall of the cap body 20 is arc-shaped. Wherein, the axis of the cambered surface is positioned at one side far away from the axis of the cap body 20.
