[0002] PVC pipe is a common pipe material in life. Due to its easy bonding and corrosion resistance, it is widely used in projects such as wire laying and water transmission. In the same installation environment, pipes of different diameters are required, so a sleeve device (transfer tube) is required as a connecting device for two PVC pipes of different diameters. However, in actual use, the existing sleeve device has the problem that the water flow in the pipe will gradually flow out along the threaded connection between the pipe and the transfer tube. In actual installation, it is also necessary to use waterproof tape and other materials to wrap around the external threads of the pipe, which is very troublesome to use. Due to the requirements of the installation environment, it is sometimes necessary to make the two sets of pipes have a certain bend angle, and the existing sleeve device cannot be easily switched between straight pipes and curved pipes, resulting in the disadvantage of poor practicality of the device.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The present invention provides a technical solution: a PVC pipe sleeve device for mining, comprising a thick joint 1, an intermediate pipe 2, a sealing bearing 21, an elastic pipe 22, a thin joint 3, an inner pipe 4, a pipe body 5, a sealing ring 6, a waterproof strip 7, a vertical rod 8, a first steering plate 9, a second steering plate 10, a fixing rod 11, a strip hole 12 and a nut 13, the right end of the thick joint 1 is installed on the left end of the intermediate pipe 2, and the right end of the intermediate pipe 2 is connected to the thin joint 3, and the two ends of the intermediate pipe 2 are respectively installed with a sealing bearing 21 and an elastic pipe 22, and the pipe wall of the pipe body 5 is located at the bottom of the pipe body 5. Between the pipe wall of the thick joint 1 and the pipe wall of the inner pipe 4, and the outer wall of the pipeline body 5 is threadedly connected to the inner wall of the thick joint 1, the thin joint 3 and the inner wall of the thick joint 1 are sealed and connected at the outer edge of the uniform sealing ring 6, and the inner pipe 4 is arranged inside the thin joint 3 and the thick joint 1, and vertical rods 8 are installed below the intermediate pipe 2 and the thin joint 3, and the first steering plate 9 and the second steering plate 10 are respectively installed at the bottom ends of the two vertical rods 8, and a vertically distributed fixing rod 11 is fixed at the end of the first steering plate 9, and the fixing rod 11 passes through the strip hole 12 and is threadedly connected with the nut 13.

[0020] The left end of the intermediate tube 2 forms a rotating connection structure with the thick joint 1 through a sealing bearing 21, and the right end of the intermediate tube 2 is sealed and connected with the thin joint 3 through an elastic tube 22. The use of the sealing bearing 21 facilitates the threaded rotation installation of the thick joint 1 or the thin joint 3 with the pipe body 5 by rotating the thick joint 1 or the thin joint 3. Compared with directly twisting the pipe body 5 with a longer length, it is more convenient and labor-saving. The use of the elastic tube 22 (the elastic tube 22 has the same structure as the bellows and is made of rubber material) can change the overall use state of the device by stretching and bending the elastic tube 22 while ensuring the normal sealing and water flow of the device as a whole.

[0021] There are two inner tubes 4, and the ends of the two inner tubes 4 close to the middle tube 2 are sealed and connected to the inner edges of the two sealing rings 6 respectively, and the horizontal center lines of the inner tube 4, the thick joint 1 and the thin joint 3 coincide with each other, and the outer wall of the inner tube 4 is welded with waterproof strips 7 distributed at equal intervals, and the upper end surface of the waterproof strips 7 is tightly fitted with the inner wall of the pipe body 5, and the waterproof strips 7 are made of rubber material. During the actual installation, the user can first place the end of the pipe body 5 made of PVC material between the thick joint 1 or the thin joint 3 and the inner tube 4, and then The thick joint 1 or the thin joint 3 is usually screwed together with the intermediate pipe 2 in the direction of the thread, so as to threadably install the pipe body 5. After the installation is completed, the inner wall of the pipe body 5 is tightly fitted with the waterproof strip 7 on the inner pipe 4. When water flows through the pipe body 5 and the sleeve device as a whole, the outward expanding water pressure will first make the water flow reach the fitting point between the pipe body 5 and the inner pipe 4, and the role of the waterproof strip 7 is to prevent further penetration of the water flow, thereby avoiding the contact between the water flow and the threaded connection, thereby achieving the purpose of leak prevention and rust prevention.

[0022] The first steering plate 9 and the second steering plate 10 are rotatably connected to the middle tube 2 and the thin joint 3 through a vertical rod 8 respectively, and the second steering plate 10 is slidably connected to the fixing rod 11 through the strip hole 12. First, the user unscrews the nut 13. When the overall length of the device needs to be changed, the user can hold the thin joint 3 and the middle tube 2 with both hands respectively, and stretch both outward. At this time, the elastic tube 22 is correspondingly elongated, so the distance between the middle tube 2 and the thin joint 3 will increase, and the fixing rod 11 on the first steering plate 9 will also slide in the strip hole 12 on the second steering plate 10 accordingly. After the sliding is completed, the nut 13 is fixed to the bottom end of the fixing rod 11, and the moving steering plate The device is fixed so that the device as a whole is fixed in the stretched state. When the use angle of the device as a whole needs to be changed, the user can pinch the fine joint 3 and deflect it to the specified angle in the horizontal direction. During the rotation, the elastic tube 22 is bent accordingly. Since it is similar to the bellows structure, the folded inner diameter will not be reduced after bending, and the first steering plate 9 and the second steering plate 10 will rotate around the vertical rod 8 accordingly, and the fixing rod 11 will also move a certain length in the strip hole 12. After bending, the nut 13 is fixed to the bottom end of the fixing rod 11 to keep the device as a whole in the bent state, thereby achieving the purpose of stretching or bending the device as a whole.

[0023] Working principle: First, the user can place the end of the PVC pipe body 5 between the thick joint 1 or the thin joint 3 and the inner tube 4, and then screw the thick joint 1 or the thin joint 3 and the intermediate tube 2 as a whole in the normal thread direction to thread the pipe body 5. After the installation is completed, the inner wall of the pipe body 5 is tightly fitted with the waterproof strip 7 on the inner tube 4. When water flows through the pipe body 5 and the sleeve device as a whole, the outward expanding water pressure will first make the water flow reach the fitting point of the pipe body 5 and the inner tube 4, and the role of the waterproof strip 7 is to prevent further penetration of the water flow, thereby avoiding the contact between the water flow and the threaded connection, thereby achieving the purpose of leak prevention and rust prevention;

[0024] First, the user unscrews the nut 13. When the length of the entire device needs to be changed, the user can hold the thin joint 3 and the middle tube 2 with both hands respectively and stretch them outward. At this time, the elastic tube 22 is correspondingly stretched, so the distance between the middle tube 2 and the thin joint 3 will become larger, and the fixing rod 11 on the first steering plate 9 will also slide in the strip hole 12 on the second steering plate 10 accordingly. After the sliding is completed, the nut 13 is fixed to the bottom end of the fixing rod 11 to fix the steering plate after the movement, so that the entire device is fixed in the stretched state. When the use of the entire device needs to be changed When the angle is reached, the user can pinch the fine joint 3 and deflect it to the specified angle in the horizontal direction. During the rotation, the elastic tube 22 bends accordingly. Since it is similar to the bellows structure, the folded inner diameter will not be reduced after the bending. The first steering plate 9 and the second steering plate 10 will rotate around the vertical rod 8 accordingly, and the fixed rod 11 will also move a certain length in the strip hole 12. After the bending, the nut 13 is fixed to the bottom end of the fixed rod 11 to keep the entire device in the bent state, thereby achieving the purpose of stretching or bending the entire device.
