Description

Technical Field

[0001] The invention relates to the technical field of PE pipes, in particular to a PE pipe capable of adaptive expansion and contraction. Background Art

[0002] PE is polyethylene plastic, which is also the most basic plastic. Plastic bags, cling film, etc. are all PE. HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin cross section. PE is widely used because of its excellent resistance to most domestic and industrial chemicals.

[0003] The existing PE pipe is usually a straight pipe with a fixed length during use. When in use, the length of the PE pipe can only be shortened by cutting it. This type of PE pipe cannot meet the actual usage requirements. Summary of the invention

[0008] In order to prevent the medium in the PE pipe body from leaking in the gap between the expansion groove and the expansion pipe, the present invention is improved in that a sealing ring is provided at the left end of the expansion groove side wall and the right end of the connecting pipe side wall.

[0009] In order to facilitate the auxiliary driving spring to limit the driving block, thereby preventing the driving block from moving during use, resulting in a decrease in the pressing performance of the fixed block, thereby causing the fixed block to move, and further affecting the change in the overall length of the PE pipe body, the present invention has improvements: a first limiting groove is set at the bottom of the fixed groove, a limiting block is slidably set in the first limiting groove, a limiting spring is set between the limiting block and the bottom of the first limiting groove, the bottom end of the rear side wall of the limiting block is set as an inclined surface, and a second limiting groove is set at the front side of the top of the driving block and the corresponding position of the limiting block.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-5A PE pipe that can be adaptively telescopic includes a PE pipe body, the PE pipe body includes a first pipe body 1, a second pipe body 2 and a telescopic pipe 3, the telescopic pipe 3 is arranged on the right side wall of the first pipe body 1, the second pipe body 2 is arranged on the right side of the first pipe body 1, a telescopic groove is arranged on the left side wall of the second pipe body 2, the telescopic groove is communicated with the second pipe body 2, the telescopic pipe 3 is adapted to the telescopic groove, the telescopic pipe 3 extends into the telescopic groove, a connecting pipe 4 is arranged on the right side wall of the telescopic pipe 3, the connecting pipe 4 extends into the second pipe body 2 and is adapted to the inner wall of the second pipe body 2, the upper and lower side walls of the telescopic groove are respectively provided with fixing grooves 5, the telescopic pipe A fixing block 6 is arranged at a position corresponding to the side wall of the fixing groove 5. A positioning device is arranged in the fixing groove 5, and the positioning device includes a positioning block 7, a driving block 8, a driving column 9 and a driving spring 10. The driving block 8 is slidably arranged in the fixing groove 5. The driving column 9 is arranged on the side wall of the rear side of the driving block 8. A driving groove is arranged at a position corresponding to the driving column 9 on the side wall of the rear side of the fixing groove 5. The driving column 9 extends into the driving groove and is slidably connected with the side wall of the driving groove. A driving spring 10 is arranged between the driving column 9 and the bottom of the driving groove. The positioning blocks 7 are evenly distributed on the side wall of the front side of the fixing groove 5. A positioning groove 11 is arranged on the right side wall of the fixing block 6 at a position corresponding to the positioning block 7. During use, the operator grasps the first tube body 1 and the second tube body 2 respectively, and then rotates the first tube body 1 and the second tube body 2 in opposite directions, so that the fixed block 6 squeezes the driving block 8, so that the fixed block 6 overcomes the elastic force of the driving spring 10 and moves to the front side of the fixed groove 5. Then the operator pulls the first tube body 1, thereby driving the fixed block 6 to move through the telescopic tube 3. When the overall length of the PE pipe body is suitable for actual use, the operator releases the second tube body 2, so that the second tube body 2 is reversed under the action of the driving spring 10, so that the fixed block 6 moves to the rear side of the fixed groove 5, so that the positioning block 7 extends into the positioning groove 11, thereby cooperating with the driving block 8 to press the fixed block 6 to fix the fixed block 6, so that the overall length of the PE pipe body remains unchanged, thereby facilitating the adaptive adjustment of the overall length of the PE pipe body according to actual use.

[0024] During use, the medium in the PE pipe body is easy to leak through the gap between the expansion groove and the expansion tube 3. For this reason, a sealing ring is provided at the left end of the expansion groove side wall and the right end of the connecting pipe 4 side wall to prevent the medium in the PE pipe body from leaking in the gap between the expansion groove and the expansion tube 3.

[0025] During use, the vibration of the PE pipe body easily drives the driving block 8 to move, thereby causing the pressure holding performance of the fixed block 6 to decrease, thereby causing the fixed block 6 to move, and further affecting the change in the overall length of the PE pipe body. For this reason, a first limiting groove is set at the bottom of the fixed groove 5, a limiting block 12 is slidably set in the first limiting groove, a limiting spring 13 is set between the limiting block 12 and the bottom of the first limiting groove, the bottom end of the rear side wall of the limiting block 12 is set as an inclined surface, and a second limiting groove 14 is set at the front side of the top of the driving block 8 and the corresponding position of the limiting block 12. The cooperation between the limiting block 12 and the side wall of the second limiting groove 14 facilitates the auxiliary driving spring 10 to limit the driving block 8, thereby preventing the driving block 8 from moving during use, resulting in a decrease in the pressure holding performance of the fixed block 6, thereby causing the fixed block 6 to move, and further affecting the change in the overall length of the PE pipe body. At the same time, through the setting of the inclined surface, it is convenient to control the driving block 8 to move under the action of gradually increasing force.

[0026] During use, the pressing effect of the driving block 8 on the fixing block 6 is relatively low. For this reason, the right side wall of the driving block 8 is configured to be arc-shaped to facilitate improving the pressing effect of the driving block 8 on the fixing block 6.

[0027] The fixing block 6 is easy to cause pollution to the medium in the PE pipe body. Therefore, the fixing block 6 is set to be made of acrylic material, so as to ensure the use strength of the fixing block 6 while preventing it from causing pollution to the medium in the PE pipe body.

[0028] When docking the PE pipe body, different interfaces need to be prepared to install and fix the first pipe body 1 and the second pipe body 2 respectively, which is not convenient. Therefore, the first pipe body 1 and the second pipe body 2 have the same size to improve the applicability of the PE pipe body, thereby facilitating its installation and fixation through the same interface.
