Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and more specifically to a double-wall corrugated pipe rear-mounted different-hole joint device. Background Art

[0002] As an important drainage and sewage pipe material, double-wall corrugated pipe is widely used in municipal, industrial and civil buildings. When connecting the main line of double-wall corrugated pipe with the small-sized branch line, the traditional method is usually to cut a hole directly on the main pipe and then insert the drainage pipe into it. Although this connection method is simple, it has the following obvious disadvantages: (1) Insufficient stability. Due to the large gap between the drainage pipe and the main pipeline of the double-wall corrugated pipe, the drainage pipe may collide with the main pipeline due to vibration or water impact during operation, resulting in damage to the double-wall corrugated pipe and expansion of the gap; (2) Poor sealing performance. The directly cut hole cannot provide a good sealing effect, resulting in the odor of sewage and exhaust gas easily overflowing from the gap, seriously reducing the comfort of the surrounding environment; (3) Easy to clog and pollute. On rainy days or when the water level rises, sewage may flow out of the gap and pollute the environment. At the same time, mud, stones and other debris may also enter the double-wall corrugated pipe through the gap, causing blockage of the pipe; (4) Shortening the service life of the pipe. Long-term leakage or seepage will cause the soil to loosen, sink or even collapse, increasing the external pressure of the double-wall corrugated pipe, thereby shortening its service life. Therefore, it is necessary to provide a more stable and reliable connection solution. By designing a special different-hole joint device, the stable connection between the drainage pipe and the double-wall corrugated pipe main line can be ensured, the risk of damage caused by vibration or collision can be eliminated, and the overall stability of the pipeline system can be improved. Utility Model Content

[0003] In order to solve the problems of poor stability and sealing and high risk of damage in the current connection method between the main line of double-wall corrugated pipe and the small-sized branch line, the utility model proposes a double-wall corrugated pipe rear-mounted different-hole joint device, which has convenient installation and reliable sealing effect.

[0004] In order to achieve the above technical effects, the technical solution of the utility model is as follows:

[0005] A double-wall corrugated pipe post-installed different-hole joint device comprises a pressure block joint and a socket joint; the pressure block joint is provided with a tapered plug-in and a penetrating tubular socket, the socket joint is provided with a penetrating tapered socket hole, the tapered plug-in of the pressure block joint is inserted in the tapered socket hole of the socket joint; the socket joint is provided with a raised first limit piece and a second limit piece, the first limit piece is arranged at the bottom of the socket joint, and the second limit piece is arranged above the first limit piece.

[0006] In this technical solution, the problems of poor sealing and low flexibility of the current connection method between the main double-wall corrugated pipe and the small-sized branch pipe are taken into consideration. The socket joint is pressed into the installation notch of the double-wall corrugated pipe by extrusion, so that the pipe wall of the double-wall corrugated pipe is buckled into the socket joint. By pressing down the pressure block joint, the two ends of the socket joint are deformed, thereby tightly clamping the pipe wall of the double-wall corrugated pipe.

[0007] Preferably, the double-wall corrugated pipe post-installed different-hole joint device also includes a sealing ring; an annular sealing groove is provided on the first limiting member, and the sealing ring is placed in the sealing groove.

[0008] Here, when the pressure block joint presses down on the socket joint, the sealing ring is squeezed at the same time and deformed to fill the tiny gap between the two, so that the gap of the double-wall corrugated pipe is effectively sealed, preventing the leakage of sewage and exhaust gas, and improving the sealing performance of the entire pipeline system.

[0009] Preferably, the pressure block joint is further provided with a first connecting piece, the bottom of which is fixedly connected to the top of the conical plug-in; and the top of the socket joint is provided with a second connecting piece matching the first connecting piece.

[0010] Preferably, the first connecting member and the second connecting member are provided with matching threads.

[0011] Here, during the installation process, the pressure block joint rotates and presses down the socket joint through the matching thread, so that both ends of the socket joint are deformed, thereby tightly clamping the pipe wall of the double-wall corrugated pipe.

[0012] Preferably, the socket joint is further provided with an annular side opening groove, and the side opening groove is arranged between the second limiting member and the first limiting member.

[0013] Preferably, the wall surface of the side opening groove close to the second limiting member is a contoured outer wall surface of the double-wall corrugated pipe.

[0014] Preferably, the wall surface of the side opening groove close to the first limiter is a contoured inner wall surface of the double-wall corrugated pipe.

[0015] Here, in order to achieve a perfect fit between the different-hole joint device and the double-wall corrugated pipe, the socket joint adopts an integrated contour design, according to the arc size and shape of the double-wall corrugated pipe of the same specifications, ensuring that during installation, the socket joint can fit tightly on the inner and outer walls of the double-wall corrugated pipe, eliminating the gap existing in the traditional installation method, thereby further enhancing the stability and sealing of the connection, and reducing the risk of leakage and seepage.

[0016] Preferably, a deformation groove is provided on one end of the second limiting member close to the second connecting member, which deforms when subjected to a downward force, thereby helping the second limiting member to clamp the double-wall corrugated pipe.

[0017] Preferably, the bottom end of the socket joint is provided with an equally divided rectangular open notch.

[0018] Here, by arranging equally divided rectangular open grooves and annular side opening grooves at the bottom of the socket joint, the strength of the different-hole joint device is guaranteed and its toughness is fully considered; during installation, the socket joint can be easily inserted into the installation port of the double-wall corrugated pipe and quickly clamped through the contouring structure; in addition, the rotating downward pressure of the pressure block joint causes the contoured outer wall surface and the contoured inner wall surface to move toward each other, so that the side opening grooves further tighten the inner and outer sides of the double-wall corrugated pipe. The process is simple and quick, and the installation efficiency is greatly improved.

[0019] Preferably, the socket joint and the pressure block joint are made of PE material.

[0020] Here, by utilizing the high flexibility and high toughness of the PE material, the different-hole joint device can deform and return to its original position during the installation process, thereby ensuring the firmness and sealing of the connection; in addition, this material also has good corrosion resistance and aging resistance, and can be used for a long time in various harsh environments without damage.

DETAILED DESCRIPTION

[0027] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0028] In order to better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent actual sizes. The description of the directions of parts such as "upper" and "lower" does not limit the present patent;

[0029] It is understandable to those skilled in the art that descriptions of certain well-known contents in the drawings may be omitted.

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, this embodiment proposes a double-wall corrugated pipe post-installed different-hole joint device, including a pressure block joint 1, a socket joint 2 and a sealing ring 3; the pressure block joint 1 is provided with a conical plug-in 11 and a through tubular socket 12, and the tubular socket 12 is used to connect the drainage pipe and the double-wall corrugated pipe; the socket joint 2 is provided with a through conical socket 21, and the conical plug-in 11 of the pressure block joint 1 is inserted in the conical socket 21 of the socket joint 2; a raised first limit piece 22 is provided at the bottom of the socket joint 2, and an annular sealing groove 221 is provided on the first limit piece 22, and the sealing ring 3 is sleeved in the sealing groove 221.

[0033] The pressure block joint 1 is also provided with a first connecting piece 13, the bottom of which is fixedly connected to the top of the conical plug-in 11; the top of the socket joint 2 is provided with a second connecting piece 24 matching the first connecting piece 13; the first connecting piece 13 and the second connecting piece 24 are provided with matching threads.

[0034] In this embodiment, the socket joint 2 is also provided with a raised second limit member 23, and the second limit member 23 is arranged between the second connecting member 24 and the first limit member 22; the second limit member 23 is provided with a deformation groove 231 on one end close to the second connecting member 24, and the deformation groove 231 will deform when subjected to downward force, thereby helping the second limit member 23 to clamp the double-wall corrugated pipe.

[0035] In actual application, the socket joint 2 is pressed into the installation gap of the double-walled corrugated pipe by extrusion, so that the pipe wall of the double-walled corrugated pipe is buckled into the socket joint 2; the block joint 1 rotates and presses the socket joint 2 through the matching thread, so that the two ends of the socket joint 2 are deformed, thereby tightly clamping the pipe wall of the double-walled corrugated pipe; this extrusion effect enables the gap of the double-walled corrugated pipe to achieve effective sealing, prevents the leakage of sewage and exhaust gas, and greatly improves the sealing performance of the entire pipeline system. On the other hand, by optimizing the joint design, sewage is prevented from flowing out of the connection under abnormal circumstances, and at the same time, mud, sand, stones and other debris are prevented from entering the interior of the pipeline, keeping the pipeline unobstructed and reducing pollution to the environment. At the same time, the sealing ring 3 is also squeezed and deformed to fill the small gap between the two, which improves the sealing and installation efficiency of the pipeline structure, and prevents the odor of sewage and exhaust gas from leaking, thereby improving the comfort of the surrounding environment.

[0036] In this embodiment, the pressure block joint 1 and the socket joint 2 are made of PE material, and further, the PE material can be HDPE. The high flexibility and high toughness of the PE material enable the different-hole joint device to deform and return to its original position during the installation process, ensuring the firmness and sealing of the connection; in addition, this material also has good corrosion resistance and anti-aging properties, which is conducive to ensuring that the different-hole joint device can be used for a long time without damage in various harsh environments, thereby extending its service life, saving manpower, reducing costs and improving stability.

[0037] Example 2

[0038] Based on Example 1, this example further describes the structure of the socket joint 2:

[0039] like Figure 2 As shown, the socket joint 2 is provided with an annular side opening groove 25 between the second limiting member 23 and the first limiting member 22 .

[0040] In order to achieve a perfect fit between the different-hole joint device and the double-wall corrugated pipe, this embodiment adopts mold shaping technology to accurately inject a product that completely matches the connection of the double-wall corrugated pipe according to the arc size and shape of the double-wall corrugated pipe of the same specifications; specifically, the wall surface of the side opening groove 25 of the socket joint 2 close to the second limit piece 23 is the contoured outer wall surface 251 of the double-wall corrugated pipe, and the wall surface of the side opening groove 25 close to the first limit piece 22 is the contoured inner wall surface 252 of the double-wall corrugated pipe.

[0041] In actual application, the rotating downward pressure of the pressure block joint 1 causes the contoured outer wall surface 251 and the contoured inner wall surface 252 to move toward each other, further fastening the inner and outer sides of the double-wall corrugated pipe. The whole process is simple and fast, greatly improving the installation efficiency.

[0042] Here, by adopting an integrated contoured design, the socket joint 2 can fit tightly on the inner and outer walls of the double-wall corrugated pipe, eliminating the gap existing in the traditional installation method, thereby greatly reducing the risk of water leakage and seepage, and further enhancing the stability and sealing of the connection.

[0043] As a preferred embodiment, the bottom end of the socket joint 2 is also provided with an equally divided rectangular open notch 26, which not only ensures the strength of the socket joint 2, but also fully considers its toughness. During installation, the socket joint 2 can be easily inserted into the installation port of the double-wall corrugated pipe and quickly clamped by the contoured structure.

[0044] Example 3

[0045] See also Figure 3 This embodiment is based on the double-wall corrugated pipe rear-mounted different-hole joint device proposed in Embodiment 1 and Embodiment 2, and further describes its use method:

[0046] In the specific implementation process, first, the sealing ring 3 is securely buckled into the sealing groove 221 on the socket joint 2, ensuring that the sealing ring 3 is placed flat and without skew, then the installation direction of the socket joint 2 is adjusted to align it with the installation notch of the double-walled corrugated pipe, and then the socket joint 2 is quickly and accurately snapped into the installation notch, so that the pipe wall of the double-walled corrugated pipe is buckled into the side opening groove 25 between the first limiter 22 and the second limiter 23. After confirming that the socket joint 2 has been successfully installed and firmly fixed on the double-walled corrugated pipe, the conical plug-in 11 of the pressure block joint 1 is slowly and evenly rotated through the thread to insert the conical socket hole 21, so that the two ends of the socket joint 2 are deformed, and at this time, the contoured outer wall surface 251 and the contoured inner wall surface 252 of the side opening groove 25 move toward each other, further buckling the inner and outer sides of the double-walled corrugated pipe until it is tightly compressed. In this process, careful observation and adjustment are required to ensure that the socket joint 2 is firmly and not loose between the inner and outer walls of the double-walled corrugated pipe. When the clamp joint 1 presses down on the socket joint 2, the sealing ring 3 is squeezed at the same time and deformed to fill the small gap between the two. Finally, apply a proper amount of glue to the drainage tube, making sure that the glue evenly covers the outer surface of the drainage tube, and then carefully install it into the tubular socket 12 of the clamp joint 1. At this point, the entire sealing installation process is successfully completed, ensuring the sealing and stability of the pipeline system.

[0047] In this embodiment, an innovative different-hole joint device and its connection technology are used to ensure the stable connection between the drainage pipe and the main double-walled corrugated pipe, eliminate the risk of damage caused by vibration or collision, improve the overall stability of the pipeline system, and enhance the sealing performance of the pipeline system, ensuring the complete sealing of the connection, preventing the odor of sewage and exhaust gas from leaking out, and improving the comfort of the surrounding environment; by optimizing the joint design, sewage is prevented from flowing out of the connection under abnormal circumstances, and at the same time, mud, sand, stones and other debris are prevented from entering the interior of the pipeline, keeping the pipeline unobstructed and reducing pollution to the environment. In addition, by eliminating hidden dangers such as water leakage and seepage, reducing the occurrence of problems such as loose soil and sinking, and reducing the external pressure of the double-walled corrugated pipe, its service life is extended and maintenance costs are reduced.
