Description

Technical Field

[0001] The utility model relates to the field of PP pipes, in particular to an anti-aging PP pipe. Background Art

[0002] PP pipe is a non-toxic, hygienic and recyclable pipe type, mainly used in indoor hot and cold water supply systems of buildings. Generally, the inner surface of the PP pipe is provided with an antibacterial layer, the outer surface of the PP pipe is provided with a protective layer, the left end of the connecting pipe is provided with a guide pipe, the inner groove of the guide pipe is provided with a sealing ring, the left end of the guide pipe is provided with an inner chamfer, the middle inner arc wall of the connecting pipe is provided with a sealing sleeve, the right side of the sealing sleeve is fixedly connected to the left side of the retaining ring, and the outer arc surface of the retaining ring is fixedly connected to the inner arc wall of the connecting pipe. However, during the use of PP pipe, it is not easy to achieve the anti-aging and anti-deformation effects, which affects the service life of the PP pipe.

[0003] According to the application number: CN202221640248.0, a PP pipe that resists aging and deformation is provided. Through the interaction of the anti-aging layer and the anti-deformation component, the solution can achieve the anti-aging and anti-deformation effects during the use of the PP pipe, so as to increase the service life of the PP pipe.

[0004] However, when connecting PP pipes, they are connected by three methods: welding, end edge welding, and connecting pipes made of different materials. The welding method is easy to damage the structure of the PP pipe, and the welded parts are easily decomposed due to high temperature. When connecting connecting pipes made of different materials, they are easy to fall off and are limited by size and need to be of specific size, which is not convenient and is not conducive to subsequent use. When connecting the PP pipes mentioned in the above patent, it is not convenient to connect PP pipes of different sizes, which is not conducive to the use of PP pipes.

[0005] Therefore, an anti-aging PP tube is needed. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide an anti-aging PP tube, which facilitates the subsequent extrusion of the elastic sheet through the elastic ring, and facilitates the fitting connection between the elastic sheet and the external tube. The anti-slip clamping block squeezes and limits the external tube when connecting a tube with a larger diameter than the tube body, thereby improving the tightness of the connection to the external tube.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] An anti-aging PP pipe comprises a PP pipe body, a connecting pipe is installed at the front end of the PP pipe body, a clamping piece is installed at the outer end of the PP pipe body, and the clamping piece is matched with the connecting pipe.

[0009] The connecting tube is convenient for subsequent connection with tube bodies of different sizes, and the opening of the connecting tube can be adjusted in conjunction with the clamping piece, so that the PP tube main body and other tube bodies are connected more tightly, and adhesive can be applied later to increase the connection strength. When the clamping piece is closer to the opening of the connecting tube, the opening of the connecting tube shrinks less, and the external tube body is squeezed, thereby limiting the position of the external tube body and satisfying the need for connecting the PP tube main body with other tube bodies. Conversely, when the clamping piece is farther away from the opening of the connecting tube, the opening of the connecting tube expands more, the external tube body is no longer squeezed, and the opening of the connecting tube is released. At this time, the user can disassemble and replace the PP tube main body and other tube bodies, which is more convenient to use.

[0010] Furthermore, the PP pipe main body comprises a pipe body, and the outer wall of the pipe body is coated with a wear-resistant and anti-oxidation coating.

[0011] The wear-resistant and anti-oxidation coating reduces the friction of the external environment on the pipe body and prevents the aging problem of the pipe body when it comes into contact with air and oxygen, thereby increasing the service life of the pipe body.

[0012] Furthermore, the connecting tube includes an elastic sheet, the elastic sheet is fixedly connected to the tube body, and a front end of the elastic sheet is provided with a plurality of slots which are arranged at equal distances.

[0013] The slots are used to facilitate the movement of the elastic sheet and to provide space for the elastic sheet to shrink. When connecting a tube with a larger diameter than the tube body, the elastic sheet shrinks and extends into the interior of the external tube. At the same time, the elastic sheet squeezes the inner wall of the external tube so that it fits tightly with the inner wall of the external tube. The surface of the elastic sheet is rough, which can increase the friction between the elastic sheet and the external tube, thereby facilitating the subsequent connection with the external tube.

[0014] Furthermore, the clamping member includes an elastic ring, which is installed on the outer end of the tube body, the elastic ring is adapted to the elastic sheet, and the outer wall of the elastic ring is installed with a plurality of anti-slip clamping blocks which are arranged at equal distances.

[0015] The elastic ring facilitates the subsequent extrusion of the elastic sheet, which facilitates the fitting connection between the elastic sheet and the external pipe. The anti-slip clamping block squeezes and limits the external pipe when connecting a pipe with a larger diameter than the pipe body, thereby improving the tightness of the connection to the external pipe.

[0016] Furthermore, the anti-slip clamping block comprises a block body, and a cavity is formed inside the block body.

[0017] Furthermore, the top end of the block is slidably connected with an anti-skid protrusion, the anti-skid protrusion passes through the top end of the block and extends to the inside of the cavity, and the bottom end of the block is rotatably connected with a connecting shaft.

[0018] Furthermore, a screw is threadedly connected to the front end of the block, and the screw passes through the block. A screw sleeve is installed on the outer wall of the screw and inside the cavity, and the screw sleeve is rotatably connected to the connecting shaft.

[0019] The position of the protrusion is limited by the block. When the screw is rotated, the screw drives the screw sleeve to move, and the screw sleeve drives the connecting shaft to move. When the screw sleeve moves to the front end, the connecting shaft moves upward, and the connecting shaft drives the protrusion to move upward. When connecting a tube with a larger diameter than the tube body, the upward moving protrusion can pressurize the inner wall of the external tube, thereby limiting the position of the external tube. On the contrary, when the screw sleeve moves to the rear end, the connecting shaft moves downward, and the connecting shaft drives the protrusion to move downward. At this time, the tube body and the external tube can be separated and replaced.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The elastic ring facilitates the subsequent extrusion of the elastic sheet, which facilitates the fitting connection between the elastic sheet and the external pipe. The anti-slip clamping block squeezes and limits the external pipe when connecting a pipe with a larger diameter than the pipe body, thereby improving the tightness of the connection to the external pipe;

[0022] 2. When the screw is rotated, the screw drives the sleeve to move, and the sleeve drives the connecting shaft to move. When the sleeve moves to the front end, the connecting shaft moves upward, and the connecting shaft drives the protrusion to move upward. When connecting a pipe with a larger diameter than the pipe body, the upward moving protrusion can pressurize the inner wall of the external pipe, thereby limiting the position of the external pipe. On the contrary, when the sleeve moves to the rear end, the connecting shaft moves downward, and the connecting shaft drives the protrusion to move downward. At this time, the pipe body and the external pipe can be separated and replaced;

[0023] 3. The slots are convenient for the elastic sheet to move and have space for the elastic sheet to shrink. When connecting a tube with a larger diameter than the tube body, the elastic sheet shrinks and extends into the inside of the external tube. At the same time, the elastic sheet squeezes the inner wall of the external tube, making it fit closely with the inner wall of the external tube. The surface of the elastic sheet is rough, which can increase the friction between the elastic sheet and the external tube, which is conducive to the subsequent connection with the external tube.

[0024] 4. The wear-resistant and anti-oxidation coating can reduce the friction of the external environment on the pipe body and prevent the aging problem of the pipe body when it comes into contact with air and oxygen, thereby increasing the service life of the pipe body.

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] Reference Figure 1 As shown, an anti-aging PP tube in a preferred embodiment of the utility model includes a PP tube body 1, a connecting tube 2 is installed at the front end of the PP tube body 1, and a clamping piece 3 is installed at the outer end of the PP tube body 1, and the clamping piece 3 is adapted to the connecting tube 2.

[0033] The connecting tube 2 is convenient for subsequent connection with tube bodies of different sizes, and the opening of the connecting tube 2 can be adjusted in conjunction with the clamping piece 3, so that the PP tube main body 1 is more tightly connected to the other tube bodies. Glue can also be applied later to increase the connection strength. When the clamping piece 3 is closer to the opening of the connecting tube 2, the opening of the connecting tube 2 shrinks less, and the external tube body is squeezed, thereby limiting the position of the external tube body and satisfying the need for connecting the PP tube main body 1 with the other tube bodies. Conversely, when the clamping piece 3 is farther away from the opening of the connecting tube 2, the opening of the connecting tube 2 expands more, the external tube body is no longer squeezed, and the opening of the connecting tube 2 is released. At this time, the user can disassemble and replace the PP tube main body 1 with other tube bodies, which is more convenient to use.

[0034] Reference Figure 2 As shown, the PP pipe body 1 includes a pipe body 101 , and the outer wall of the pipe body 101 is coated with a wear-resistant and anti-oxidation coating 102 .

[0035] The wear-resistant and anti-oxidation coating 102 reduces the friction of the tube body 101 from the outside and prevents the tube body 101 from aging when in contact with oxygen in the air, thereby increasing the service life of the tube body 101.

[0036] The connecting tube 2 includes an elastic sheet 201 , which is fixedly connected to the tube body 101 . A plurality of slots 202 arranged at equal intervals are formed at the front end of the elastic sheet 201 .

[0037] The slot 202 facilitates the movement of the elastic sheet 201 and provides space for the elastic sheet 201 to shrink. When connecting a tube with a larger diameter than the tube body 101, the elastic sheet 201 shrinks and extends into the interior of the external tube. At the same time, the elastic sheet 201 squeezes the inner wall of the external tube so that it fits tightly with the inner wall of the external tube. The surface of the elastic sheet 201 is rough, which can increase the friction between the elastic sheet 201 and the external tube, thereby facilitating the subsequent connection with the external tube.

[0038] Reference Figure 3 As shown, the clamping member 3 includes an elastic ring 301, which is installed on the outer end of the tube body 101, the elastic ring 301 is adapted to the elastic sheet 201, and the outer wall of the elastic ring 301 is installed with multiple anti-slip clamping blocks 302 arranged equidistantly.

[0039] The elastic ring 301 facilitates the subsequent squeezing of the elastic sheet 201, and facilitates the fitting connection between the elastic sheet 201 and the external tube. The anti-slip clamping block 302 squeezes and limits the external tube when connecting a tube with a larger diameter than the tube body 101, thereby improving the tightness of the connection to the external tube.

[0040] Reference Figure 4 As shown, the anti-slip clamping block 302 includes a block body 30201 , and a cavity 30202 is formed inside the block body 30201 .

[0041] The top of the block 30201 is slidably connected with an anti-skid protrusion 30203, which passes through the top of the block 30201 and extends to the inside of the cavity 30202. The bottom of the block 30201 is rotatably connected with a connecting shaft 30204.

[0042] The front end of the block 30201 is threadedly connected with a screw rod 30205 , which penetrates the block 30201 . A screw sleeve 30206 is installed on the outer wall of the screw rod 30205 and inside the cavity 30202 . The screw sleeve 30206 is rotatably connected to the connecting shaft 30204 .

[0043] The position of the protrusion 30203 is limited by the block 30201. When the screw 30205 is rotated, the screw 30205 drives the screw sleeve 30206 to move, and the screw sleeve 30206 drives the connecting shaft 30204 to move. When the screw sleeve 30206 moves to the front end, the connecting shaft 30204 moves upward, and the connecting shaft 30204 drives the protrusion 30203 to move upward. When connecting a tube with a larger diameter than the tube body 101, the upward moving protrusion 30203 can pressurize the inner wall of the external tube, thereby limiting the position of the external tube. On the contrary, when the screw sleeve 30206 moves to the rear end, the connecting shaft 30204 moves downward, and the connecting shaft 30204 drives the protrusion 30203 to move downward. At this time, the tube body 101 and the external tube can be separated and replaced.

[0044] Working principle: when connecting an external tube body with a larger diameter than the tube body 101, the elastic sheet 201 of the connecting tube 2 is contracted through the elastic ring 301 of the clamping piece 3, and the elastic ring 301 is moved to a suitable position of the elastic sheet 201, and then the contracted elastic sheet 201 is extended into the interior of the external tube body with a larger diameter than the tube body 101, and the position of the elastic ring 301 is adjusted again until the elastic sheet 201 can fit the inner wall of the external tube body, and then when the screw rod 30205 is rotated, the screw rod 30205 drives the screw sleeve 30206 to move, and the screw sleeve 30206 drives the connecting shaft 30204 to move, and when the screw sleeve 30206 moves to the front end, the connecting shaft 30204 moves upward, and the connecting shaft 30204 drives the protrusion 30203 to move upward, When connecting a tube with a larger diameter than the tube body 101, the upwardly moving protrusion 30203 can pressurize the inner wall of the external tube, thereby limiting the position of the external tube. If connecting an external tube with a smaller diameter than the tube body 101, extend the external tube into the tube body 101 from the connecting tube 2, and then adjust the position of the elastic ring 301 of the clamping part 3 until the elastic sheet 201 of the connecting tube 2 fits the outer wall of the external tube. Subsequently, a strong adhesive can be applied to further increase the tightness between the elastic sheet 201 of the connecting tube 2 and the external tube. The wear-resistant and anti-oxidation coating 102 reduces the friction of the external environment on the tube body 101, and prevents the aging problem of the tube body 101 when it comes into contact with air oxygen, thereby increasing the service life of the tube body 101.
