[0006] Preferably, the second nut is conical, so that the second nut can press the screw block tightly.

[0007] Preferably, the diameter of the screw block is greater than the diameter of the screw rod. Accordingly, the screw block can be sleeved on the screw rod.

[0008] Preferably, an auxiliary structure is provided at one end of the screw rod, and the auxiliary structure comprises a washer, the washer is sleeved on one end of the screw rod, and a groove is formed on the inner wall of the washer.

[0009] Preferably, the groove is in an arc shape, thereby enabling the washer to be compatible with the screw.

[0010] Preferably, the grooves are distributed circumferentially on the washer, so that the grooves can fit around the screw.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when actually used, by arranging the rod body, the water stop plate, the screw sleeve, the screw rod, the No. 1 nut, the gasket, the screw block, the notch and the No. 2 nut, the No. 2 nut is tightened so that the screw block can be fastened to the screw rod, which prevents the nut and the gasket from loosening and improves the stability of the screw rod.

[0013] 2. In the present utility model, in actual use, by providing an auxiliary structure, the screw can adapt to irregular or uneven contact surfaces during installation, which is beneficial to actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] For example, see Figure 1-3The utility model provides a technical solution: a water-stop screw with a telescopic structure, comprising a rod body 1, a water-stop plate 2, a screw sleeve 3, a screw rod 4, a No. 1 nut 5, a gasket 6, a screw block 7, a notch 8 and a No. 2 nut 9, a water-stop plate 2 is arranged in the middle of the rod body 1, screw sleeves 3 are threadedly connected at both ends of the rod body 1, a screw sleeve 3 is threadedly connected at one end of the screw sleeve 3, a No. 1 nut 5 and a gasket 6 are threadedly connected on the surface of the screw rod 4, a screw block 7 is arranged on one side of the No. 1 nut 5 and the gasket 6, the diameter of the screw block 7 is greater than the diameter of the screw rod 4, the screw block 7 is sleeved on the screw rod 4, a notch 8 is opened between the screw blocks 7, a No. 2 nut 9 is threadedly connected on the surface of the screw block 7, and the No. 2 nut 9 is conical, and the conical No. 2 nut 9 can squeeze the screw block 7 to make it close to the outer wall of the screw rod 4.

[0023] For example 2, please refer to Figure 2 and Figure 4 An auxiliary structure is provided at one end of the screw rod 4, and the auxiliary structure includes a washer 10. The washer 10 is sleeved on one end of the screw rod 4. A groove 11 is opened on the inner wall of the washer 10. The shape of the groove 11 is arc-shaped, and the grooves 11 are distributed circumferentially on the washer 10.

[0024] Working principle: In actual use, by setting the rod body 1, water stop plate 2, screw sleeve 3, screw rod 4, No. 1 nut 5, gasket 6, screw block 7, notch 8 and No. 2 nut 9, first, by rotating the screw rod 4 and the rod body 1, it can move in the meshing screw sleeve 3, thereby achieving the effect of extending the screw rod 4, then, the screw rod 4, the rod body 1 and the water stop plate 2 are arranged at the specified position, and finally the screw rod 4 is locked by the gasket 6 and No. 1 nut 5. When the No. 1 nut 5 is tightened, it is tightened on the screw block 7 by screwing in the No. 2 nut 9. Since the screw block 7 is not tightened, the screw block 7 is tightened. The opening 8 is divided into two halves. When the conical No. 2 nut 9 is screwed in, the screw block 7 is squeezed and will be tightly attached to the screw rod 4, thereby achieving the effect of tightening the No. 1 nut 5 and the gasket 6 to prevent them from loosening. In actual use, by setting an auxiliary structure and arranging washers 10 at both ends of the screw rod 4, the position of the sealing ring can be independently adjusted while the screw rod 4 is screwed in to adapt to irregular or uneven contact surfaces, thereby enabling it to provide efficient sealing effects in more complex and changeable installation environments. At the same time, the groove 11 on the inner wall of the gasket 10 can fit the surface of the screw rod 4.
