[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0017] Please refer to Figures 1-4 In the embodiments of the utility model, the anti-skid clamp structure comprises an upper clamp 1 and a lower clamp 2, the butt joint end of the upper clamp 1 and the lower clamp 2 is integrally formed with a fixed lug 3 protruding outward, a circular hole for the locking bolt 4 to pass through is formed in the inside of the fixed lug 3, the locking nut 5 is threadedly connected to the outer wall of the locking bolt 4 below the circular hole, and the inner periphery of the upper clamp 1 and the lower clamp 2 is provided with an anti-skid mechanism.

[0018] In the embodiments, when the butt joint end of the water pipe is clamped, the upper clamp 1 and the lower clamp 2 are clamped on the butt joint end of the two water pipes, then the locking bolt 4 is passed through the circular hole of the fixed lug 3, after the locking bolt 4 is passed through, the locking nut 5 is threadedly connected to the outer wall of the locking bolt 4 and is effectively tightened, at this time, the locking nut 5 and the end of the locking bolt 4 clamp the fixed lug 3, and at this time, the butt joint end of the two water pipes can be effectively clamped;

[0019] In the above process, the anti-skid mechanism is pressed and tightly pressed on the outer wall of the water pipe, so as to improve the friction of the butt joint position, avoid the rotation of the upper clamp 1 and the lower clamp 2 caused by stress during the locking process, and avoid the inconvenience caused by the rotation.

[0020] Please pay attention to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The anti-skid mechanism comprises a connecting groove 6 distributed along the extending track of the upper clamp 1 and the lower clamp 2 and arranged in the inner periphery of the upper clamp 1 and the lower clamp 2, the cross section of the connecting groove 6 is in a convex structure, the anti-skid mechanism further comprises a connecting ring 8 inserted into the inner wall of the connecting groove 6, the outer wall of the connecting ring 8 is consistent with the inner wall of the connecting groove 6, and the inner periphery diameter of the connecting ring 8 is equal to the inner periphery diameter of the upper clamp 1 and the lower clamp 2, the anti-skid mechanism further comprises a ring-shaped sealing ring 7 integrally formed in the inner periphery of the connecting ring 8, the outer periphery diameter of the ring-shaped sealing ring 7 is equal to the inner periphery diameter of the upper clamp 1 and the lower clamp 2, and the inner periphery of the ring-shaped sealing ring 7 is integrally formed with a plurality of inward protruding extrusion sealing rings 9.

[0021] In the embodiment, when the upper clamp 1 and the lower clamp 2 are clamped on the outer wall of the two sections of pipes, the extrusion sealing rings 9 are located on the outer wall of the pipes, the upper clamp 1 and the lower clamp 2 increase the friction force with the outer wall of the pipes through the extrusion sealing rings 9, and the upper clamp 1 and the lower clamp 2 are not prone to rotating under the friction resistance, the ring-shaped sealing ring 7 and the extrusion sealing ring 9 are deformed under stress during the locking process of the locking bolt 4 and the locking nut 5, so that the friction resistance exists and gradually increases during the installation process, and the problem that the upper clamp 1 and the lower clamp 2 rotate due to stress during the installation process is avoided.

[0022] When the ring-shaped sealing ring 7 and the extrusion sealing ring 9 are disassembled from the upper clamp 1 and the lower clamp 2, the replacement is observed by rotating the ring-shaped sealing ring 7, the ring-shaped sealing ring 7 drives the connecting ring 8 to rotate in the connecting groove 6 until the connecting ring 8 is separated from the connecting groove 6, at which time the disassembly is completed, then a new connecting ring 8 is rotated and clamped into the connecting groove 6 until the connecting ring 8 is completely inserted into the connecting groove 6, and the replacement is completed, which is relatively convenient during replacement.
