DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1-3 , a dust-proof cover for a plastic pipe, including a plastic pipe 1 and a dust-proof cover body 2. Two semi-circular clamping blocks 3 are provided inside the dust-proof cover body 2, and a T-shaped sealing ring gasket 10 is fixedly connected to the inner wall of the dust-proof cover body 2 on one side of the semi-circular clamping block 3. The T-shaped sealing ring gasket 10 is slidably connected to the side wall of the plastic pipe 1, and a driving device is provided above the semi-circular clamping block 3.

[0021] As can be seen from the above structure, by setting the plastic pipe 1, the dust cover body 2, the semi-circular clamping block 3, the T-shaped sealing ring gasket 10, the semi-circular clamping block 3 and the driving device to cooperate with each other. First, the dust cover body 2 is slidably connected to both ends of the plastic pipe 1, so that the T-shaped sealing ring gasket 10 abuts against both ends of the plastic pipe 1 to seal the ports of the plastic pipe 1. Then, the driving device can be used to push the semi-circular clamping blocks 3 to move in opposite directions at the same time, and then abut against the inner wall of the plastic pipe 1 to clamp the plastic pipe 1, fixing the dust cover body 2 at both ends of the plastic pipe 1, reducing the possibility of the dust cover body 2 falling off, and the structure is simple and easy to use.

[0022] Furthermore, the driving device includes a moving chute 4 opened on the bottom surface of the dust cover body 2, and a bidirectional lead screw 5 is rotatably connected to the inner wall of the moving chute 4. Opposite threads are provided on both sides of the bidirectional lead screw 5 and are threadedly connected to moving blocks 6, and the bottom surface of the moving block 6 is fixedly connected to the upper surface of the semi-circular clamping block 3. A rotating groove 13 with an upper opening is opened inside the moving chute 4, and a rotating sleeve 7 is fixedly connected to the side wall of the bidirectional lead screw 5 located inside the rotating groove 13. By setting the moving chute 4, the bidirectional lead screw 5, the moving blocks 6, the semi-circular clamping blocks 3, the rotating groove 13 and the rotating sleeve 7 to cooperate with each other, after the dust cover body 2 is slidably connected to both ends of the plastic pipe 1, the rotating sleeve 7 is rotated to drive the bidirectional lead screw 5 to rotate, so that the moving blocks 6 threadedly connected to the opposite threads of the bidirectional lead screw 5 will drive the two groups of semi-circular clamping blocks 3 to move in opposite directions. When the side wall of the semi-circular clamping block 3 abuts against the inner wall of the plastic pipe 1, the plastic pipe 1 will be clamped, and then the dust cover body 2 will be fixed at both ends of the plastic pipe 1, reducing the possibility of the dust cover body 2 slipping during transportation, and the operation is simple and easy to use.

[0023] Furthermore, a plurality of strip-shaped blocks 8 are fixedly connected to the side wall of the rotating sleeve 7. By setting the strip-shaped blocks 8, the friction force is enhanced, which is convenient for rotating the rotating sleeve 7.

[0024] Furthermore, a pointing arrow 12 is provided on the upper surface of the dust cover body 2 on one side of the rotating sleeve 7. By setting the pointing arrow 12, when the rotating sleeve 7 moves in the direction pointed by the pointing arrow 12, it will drive the two groups of semi-circular clamping blocks 3 to move to one side of the plastic pipe 1 through the bidirectional lead screw 5 and the moving blocks 6, and then clamp the plastic pipe 1. When moving in the opposite direction of the direction pointed by the pointing arrow 12, it will drive the two groups of semi-circular clamping blocks 3 to approach each other through the bidirectional lead screw 5 and the moving blocks 6, and then loosen the plastic pipe 1.

[0025] Furthermore, an anti-slip rubber strip 9 is fixedly connected to the side wall of the semi-circular clamping block 3 located on one side of the plastic pipe 1; by providing the anti-slip rubber strip 9, when the semi-circular clamping block 3 clamps the plastic pipe 1, the semi-circular clamping block 3 will push the anti-slip rubber strip 9 against the side wall of the plastic pipe 1, thereby increasing the friction force and preventing the semi-circular clamping block 3 from slipping off, providing the stability of clamping.

[0026] Furthermore, guiding inclined surfaces 11 are provided on the bottom surfaces of both the dust-proof cover body 2 and the semi-circular clamping block 3; by providing the guiding inclined surfaces 11, a certain guiding effect is provided, facilitating the plastic pipe 1 to slide into the annular clamping groove formed by the dust-proof cover body 2 and the semi-circular clamping block 3 along the guiding inclined surfaces 11.
