Specific embodiments

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0024] According to Figure 1 、 2 As shown in Figures 3, 4, 5, a water supply and drainage pipe anti-seepage device is proposed in this embodiment, which includes a first pipe joint 1, a diversion pipe 11 and a second pipe joint 2. The first pipe joint 1 is sleeved outside the diversion pipe 11, and the first pipe joint 1 is fixedly connected to the diversion pipe 11. The upper end of the second pipe joint 2 is fixedly connected with an insertion joint 21, and the lower end of the diversion pipe 11 is inserted into the insertion joint 21 and is in plug-in fit with the insertion joint 21;

[0025] When the diversion pipe 11 is docked with other pipes, the first pipe joint 1 on the diversion pipe 11 will be plugged together with the second pipe joint 2 on the other pipes.

[0026] A threaded sleeve 4 is sleeved outside the second pipe joint 2. The threaded sleeve 4 is fixedly connected to the second pipe joint 2. The upper end of the threaded sleeve 4 is movably connected with multiple petals of external threads 33, and each petal of external threads 33 surrounds the first pipe joint 1;

[0027] A nut 3 for constricting each petal of rubber clamping blocks 32 is sleeved outside the threaded sleeve 4. The threaded sleeve 4 is threadedly connected to the nut 3. External threads 33 for cooperating with the nut 3 are provided on the outside of the rubber clamping blocks 32, and a positioning structure for restricting the rotation of the nut 3 is provided on the outside of the second pipe joint 2.

[0028] Rotate the nut 3, screw the nut 3 from the outside of the threaded sleeve 4 to the outside of each petal-shaped rubber clamping block 32. As the nut 3 moves upward, each petal-shaped rubber clamping block 32 will be simultaneously constricted, firmly fixing the first pipe joint 1 and the second pipe joint 2. After the nut 3 completes the tightening of each petal-shaped rubber clamping block 32, the positioning structure will restrict the rotation of the nut 3 from the outside of the second pipe joint 2, preventing the nut 3 from falling off the rubber clamping block 32 and providing better stability.

[0029] To increase the sealing performance at the insertion joint of the first pipe joint 1 and the second pipe joint 2, a sealing groove 12 is provided on the lower end face of the first pipe joint 1. The insertion joint 21 is inserted into the sealing groove 12 and mates with it. A sealing rubber ring is provided at the connection between the insertion joint 21 and the sealing groove 12. When the first pipe joint 1 and the second pipe joint 2 are docked, the lower end of the diversion pipe 11 is inserted into the second pipe joint 2, and the insertion joint 21 at the upper end of the second pipe joint 2 is inserted into the sealing groove 12 provided on the lower end face of the first pipe joint 1, increasing the fit between the first pipe joint 1 and the second pipe joint 2. The sealing rubber ring is arranged between the insertion joint 21 and the sealing groove 12 to prevent liquid leakage.

[0030] Regarding the positioning structure:

[0031] The positioning structure includes a fixing frame 5. The lower end of the fixing frame 5 is fixedly connected to the outside of the second pipe joint 2. A positioning bolt 51 is assembled at the upper end of the fixing frame 5. The positioning bolt 51 passes through the fixing frame 5 and is threadedly connected to the fixing frame 5. The positioning bolt 51 and the rubber clamping block 32 are at the same height. Threaded holes 31 are provided on the outside of the nut 3, and the threaded holes 31 are threadedly connected to the positioning bolt 51.

[0032] Rotate the nut 3, screw the nut 3 from the outside of the threaded sleeve 4 to the outside of each petal-shaped rubber clamping block 32. Each petal-shaped rubber clamping block 32 will be simultaneously constricted. After firmly fixing the first pipe joint 1 and the second pipe joint 2, one of the threaded holes 31 on the outside of the nut 3 will correspond to the positioning bolt 51 at the upper end of the fixing frame 5. The axis of the positioning bolt 51 coincides with the axis of this threaded hole 31. Rotate the positioning bolt 51 and screw the positioning bolt 51 towards the nut 3. The positioning bolt 51 is screwed into the threaded hole 31 to restrict the rotation of the nut 3.

[0033] It should be further noted that threaded holes 31 are provided on each side edge of the nut 3. No matter which direction the nut 3 is screwed to, there is a threaded hole 31 on the side of the nut 3 facing the positioning bolt 51 corresponding to the positioning bolt 51.

[0034] In a preferred solution, a handle 6 is provided on the outside of the nut 3 for convenient rotation of the nut 3. One end of the handle 6 is fixedly connected with a bolt head 61, and the bolt head 61 is threadedly connected to the threaded hole 31. When rotating the nut 3, screw the bolt head 61 on the handle 6 into the threaded hole 31, and just hold the handle 6. There will be no slippage when rotating the nut 3.

[0035] Since the handle 6 is fixedly connected to the nut 3 in a detachable manner, when the handle 6 is removed from the nut 3, there will be a problem of loss. In the preferred solution, a chain 62 is provided at one end of the handle 6 away from the bolt head 61. The chain 62 is movably connected to the handle 6, and one end of the chain 62 away from the handle 6 is movably connected to the lower end of the fixing frame 5. The handle 6 is fixed to the fixing frame 5 through the chain 62. With the chain 62, the problem of the handle 6 falling off will no longer occur.

[0036] The working principle of this application:

[0037] When the diversion pipe 11 is docked with other pipes, the first pipe joint 1 on the diversion pipe 11 will be inserted into the second pipe joint 2 on the other pipes. Rotate the nut 3, and screw the nut 3 from the outside of the threaded sleeve 4 to the outside of each rubber clamping block 32. As the nut 3 moves upward, each rubber clamping block 32 will simultaneously contract, firmly fixing the first pipe joint 1 and the second pipe joint 2. After the nut 3 completes the tightening of each rubber clamping block 32, the positioning structure will restrict the rotation of the nut 3 from the outside of the second pipe joint 2, so that the nut 3 will not fall off the rubber clamping block 32, and the stability is better.
