Description

Technical Field

[0001] This application relates to the technical field of pipes, and in particular to an integrated H-type pipe. Background Technology

[0002] In drainage piping systems, the double riser design is a common structure. The double riser consists of a drainage riser and a vent riser, which are connected by an H-pipe. The H-pipe and the vent riser can prevent pressure differences in the drainage riser, thereby preventing water seal failure and wastewater overflow.

[0003] In related technologies, the integrated H-shaped pipe includes a first pipe and a second pipe, and a connecting pipe is injection molded between the first pipe and the second pipe. The connecting pipe is bent towards the second pipe, and both ends of the connecting pipe are connected to the first pipe and the second pipe, respectively.

[0004] Integrated H-type pipes are typically injection molded using an injection mold with an arc-shaped core puller. Because the connecting pipe bends towards the second pipe, the connecting pipe has an asymmetrical structure, which means that the installation direction of the integrated H-type pipe cannot be changed, causing great inconvenience to installers. Utility Model Content

[0005] To address the problem of inconvenient installation of integrated H-type pipes, this application provides an integrated H-type pipe.

[0006] This application provides a one-piece H-shaped tube, which adopts the following technical solution:

[0007] An integrated H-shaped pipe includes a first pipe and a second pipe. A connecting pipe is injection molded between the first pipe and the second pipe. The two ends of the connecting pipe are respectively connected to the first pipe and the second pipe. The connecting pipe includes a first arc portion and a second arc portion. The first arc portion is disposed on the first pipe and bends towards the second pipe. The first arc portion is tangent to the first pipe. The second arc portion is disposed on the second pipe and bends towards the first pipe. The second arc portion is tangent to the second pipe. The first arc portion and the second arc portion are centrally symmetrically arranged.

[0008] By adopting the above technical solution, the manufacturer uses two arc-shaped core pullers to enter from the opposite ports of the first and second pipes, respectively. The two arc-shaped core pullers abut and fit together at the connection point of the first and second arc-shaped portions. The first arc-shaped portion bends towards the second pipe, tangent to the first pipe, and the second arc-shaped portion bends towards the first pipe, tangent to the second pipe. This allows the two arc-shaped core pullers to be pulled out from their respective pipes after injection molding, thereby achieving the integrated molding of the H-shaped pipe and further improving production efficiency. The symmetrical arrangement of the first and second arc-shaped portions makes the overall pipe a symmetrical structure, enhancing structural stability and adapting to more installation scenarios. It also allows the installation direction of the integrated H-shaped pipe to be changed, providing great convenience for workers installing the pipes.

[0009] Optionally, the connecting pipe is provided with a fixing ring, which abuts against the first pipe.

[0010] By adopting the above technical solution, the fixing ring abuts against the first pipe, making the fixation between the connecting pipe and the first pipe more reliable, enhancing the stability of the connection between the connecting pipe and the first pipe, and reducing the occurrence of damage to the connection between the connecting pipe and the first pipe due to water flow impact.

[0011] Optionally, the outer surface of the connecting pipe is provided with reinforcing ribs, the reinforcing ribs extend along the bending direction of the connecting pipes, and the two ends of the reinforcing ribs are respectively connected to the first pipe and the second pipe.

[0012] By adopting the above technical solution, the first pipe and the second pipe are connected at both ends of the reinforcing rib, making the fixation between the connecting pipe, the first pipe and the second pipe more reliable, improving the stability of the overall pipe structure, and reducing the possibility of the connecting pipe breaking due to water flow impact.

[0013] Optionally, the width of the reinforcing rib gradually increases along the direction from the second pipe to the first pipe, and the reinforcing rib abuts against the fixing ring.

[0014] By adopting the above technical solution, the width of the reinforcing rib gradually increases along the direction from the second pipe to the first pipe, thereby increasing the contact area between the reinforcing rib and the fixing ring. This allows the reinforcing rib to better distribute the load to other parts, thereby reducing localized stress concentration, reinforcing the connection of the connecting pipes, and improving the overall stability of the pipeline.

[0015] Optionally, the fixing ring is provided with a fixing plate, the fixing plate abutting against the reinforcing rib, the first pipe has an inlet for fluid to enter, the reinforcing rib is located on the side of the first arc portion away from the inlet, and the fixing plate is located on the side of the reinforcing rib away from the first arc portion.

[0016] By adopting the above technical solution, since the reinforcing rib is located on the side of the first arc portion away from the inlet, the fluid will be subjected to a large impact force when entering from the inlet. The fixing plate abuts against the reinforcing rib, and the fixing plate is located on the side of the reinforcing rib away from the first arc portion, so that the fixing plate further supports the reinforcing rib, thereby reducing the possibility of the reinforcing rib being displaced due to impact, and making the connection between pipes more stable.

[0017] Optionally, the fixing plate, reinforcing ribs, and first pipe are arranged in a triangular pattern.

[0018] By adopting the above technical solution, the fixing plate, reinforcing rib, and first pipe are arranged in a triangle, making the fixation between the fixing plate, reinforcing rib, and first pipe more reliable, thereby further enhancing the overall stability of the pipeline.

[0019] Optionally, the outer surface of the first pipe is provided with an annular limiting part, which is used to reinforce the first pipe.

[0020] By adopting the above technical solution, the stability of the first pipe structure is enhanced by the ring-shaped limiting part on the outer surface of the first pipe, the possibility of deformation of the first pipe due to external pressure is reduced, thereby improving the service life of the overall pipe.

[0021] Optionally, a protruding ring is provided on the outer surface of the first pipe, the protruding ring being used to pre-position other pipes; when the protruding ring abuts against other pipes, the first pipe is connected to other pipes.

[0022] By adopting the above technical solution, when the convex ring abuts against other pipes, the first pipe is connected to other pipes, which makes it easier for workers to insert other pipes into the first pipe. Workers can determine whether the pipes are aligned by the contact between other pipes and the convex ring, thereby improving the efficiency of pipe installation.

[0023] Optionally, the convex ring is provided with an inclined surface, and the distance from the inclined surface to the limiting part gradually decreases along the outer surface of the first pipe in the direction close to the axis of the first pipe. The inclined surface is used to guide other pipes to be inserted into the first pipe.

[0024] By adopting the above technical solution, the distance from the inclined plane to the limiting part gradually decreases along the outer surface of the first pipe in the direction close to the axis of the first pipe, so that other pipes can be inserted into the first pipe more smoothly along the inclined plane, which provides convenience for workers to install pipes.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The manufacturer uses two arc-shaped core pullers to enter from the opposite ports of the first and second pipes, respectively. The two arc-shaped core pullers abut and fit together at the connection point of the first and second arc sections. The first arc section bends towards the second pipe, tangent to the first pipe, and the second arc section bends towards the first pipe, tangent to the second pipe. This allows the two arc-shaped core pullers to be pulled out from their respective pipes after injection molding, thus achieving the one-piece molding of the integrated H-shaped pipe and further improving production efficiency. The symmetrical arrangement of the first and second arc sections makes the overall pipe a symmetrical structure, enhancing structural stability and adapting to more installation scenarios. It also allows the installation direction of the integrated H-shaped pipe to be changed, providing great convenience for workers installing the pipes.

[0027] 2. By using a fixing ring to abut against the first pipe, the fixation between the connecting pipe and the first pipe is made more secure, enhancing the stability of the connection between the connecting pipe and the first pipe and reducing the possibility of damage to the connection between the connecting pipe and the first pipe due to water flow impact.

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0032] Example 1

[0033] This embodiment discloses a one-piece H-shaped tube. (Refer to...) Figure 1 A one-piece H-shaped pipe includes a first pipe 1 and a second pipe 2, which are arranged parallel to each other. The first pipe 1 has an inlet 11 for fluid to enter. A connecting pipe 3 is injection molded between the first pipe 1 and the second pipe 2, and the two ends of the connecting pipe 3 are respectively connected to the first pipe 1 and the second pipe 2.

[0034] Reference Figure 1The connecting pipe includes a first arc portion 31 and a second arc portion 32, which are centrally symmetrically arranged. The first arc portion 31 is integrally formed on the first pipe 1, and is located near the inlet 11 of the first pipe 1. The first arc portion 31 bends towards the second pipe 2 and is tangent to the outer surface of the first pipe 1. The second arc portion 32 is integrally formed on the second pipe 2, and bends towards the first pipe 1, and is tangent to the outer surface of the second pipe 2.

[0035] Reference Figure 1 Two fixing blocks 33 are provided on the outer surface of the connecting pipe 3. The two fixing blocks 33 abut against the first pipe 1 and the second pipe 2 respectively. The fixing blocks 33 are used to fix the connection of the connecting pipe 3.

[0036] Reference Figure 1 Both sides of the outer surface of the first pipe 1 and both sides of the outer surface of the second pipe 2 are fitted with annular limiting portions 12, which are used to reinforce the first pipe 1 and the second pipe 2. Both the outer surfaces of the first pipe 1 and the second pipe 2 are fitted with protruding rings 13, which are located on the side of the limiting portion 12 away from the other limiting portion 12 on the same pipe. When other pipes abut against the protruding rings 13, the first pipe 1 is aligned and connected with the other pipes.

[0037] The implementation principle of Example 1 is as follows: When the staff installs other pipes on the first pipe 1, the staff first abuts the other pipes against the convex ring 13. At this time, the first pipe 1 is connected to the other pipes, realizing the installation of the first pipe 1 and the other pipes.

[0038] Example 2

[0039] Reference Figure 2 The difference between this embodiment and embodiment 1 is that an inclined surface 14 is provided on the inner surface of the convex ring 13. The distance from the inclined surface 14 on the first pipe 1 to the limiting part 12 gradually decreases along the direction of the outer surface of the first pipe 1 close to the axis of the first pipe 1. The distance from the inclined surface 14 on the second pipe 2 to the limiting part 12 gradually decreases along the direction of the outer surface of the second pipe 2 close to the axis of the second pipe 2. The inclined surface 14 is used to guide other pipes to be inserted into the first pipe 1 and the second pipe 2.

[0040] Reference Figure 2Both ends of the connecting pipe 3 are fitted with fixing rings 34, which abut against the first pipe 1 and the second pipe 2, respectively. Reinforcing ribs 35 are fixedly connected to the outer surfaces of opposite sides of the connecting pipe 3. One reinforcing rib 35 is located on the side of the first arc portion 31 away from the inlet 11, and the other reinforcing rib 35 is located on the side of the second arc portion 32 closer to the inlet 11. The reinforcing ribs 35 extend along the bending direction of the connecting pipe 3, and both ends of the reinforcing ribs 35 abut against the fixing rings 34. The width of the reinforcing rib 35 gradually decreases along the direction from the end face of the reinforcing rib 35 to the connection point of the first arc portion 31 and the second arc portion 32.

[0041] Reference Figure 2 A fixing plate 36 is fixedly connected to the outer surface of the fixing ring 34. The fixing plate 36 abuts against the reinforcing rib 35. The fixing plate 36 near the first pipe 1 is located on the side of the reinforcing rib 35 away from the inlet 11, and the other fixing plate 36 near the second pipe 2 is located on the side of the reinforcing rib 35 near the inlet 11. The fixing plate 36, the reinforcing rib 35 and the first pipe 1 are arranged in a triangle.

[0042] The implementation principle of Example 2 is as follows: When the staff installs other pipes on the first pipe 1, the staff first inserts the other pipes into the first pipe 1 along the inclined direction of the inclined surface 14, so that the other pipes abut against the protruding ring 13. At this time, the first pipe 1 is connected to the other pipes, realizing the installation of the first pipe 1 and the other pipes.
