Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a connection structure for municipal water supply and drainage pipes. Background Technology

[0002] The connection structure of municipal water supply and drainage pipelines refers to how different types of pipelines are connected into a whole to ensure the normal operation of water supply and drainage. When designing the connection structure of municipal water supply and drainage pipelines, a variety of factors need to be considered, such as pipeline diameter, materials and usage conditions.

[0003] In existing technologies, when connecting two municipal drainage pipes, flanges are typically used for connection and fixation. A sealing ring is placed between the two flanges to achieve a seal. However, connecting via flanges requires the use of multiple bolts and nuts for fixation, which reduces the efficiency of workers connecting the two drainage pipes. Therefore, the relevant technology needs to be improved and designed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a connection structure for municipal water supply and drainage pipelines.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal water supply and drainage pipeline connection structure, comprising a connecting ring sleeved on two pipeline bodies to be connected, wherein a circular plate is fixedly sleeved on one end of one of the pipeline bodies, the inner surface of the connecting ring is fitted and fixed to the arc surface of the circular plate, and an annular connecting member is integrally formed on the outer wall of the other pipeline body near the end of the pipeline body, the annular connecting member having an annular protrusion on its outer side, the cross-section of the annular protrusion being quadrilateral; a notch is provided at the intersection between the end of the connecting ring away from the circular plate and the outer wall of the connecting ring, the notch having multiple parallel... The axes of the connecting rings are evenly distributed, and each notch is provided with an elastic fixing component. The elastic fixing component includes a mounting rod rotatably installed in the notch, a clamping wheel rotatably connected to the end of the mounting rod away from the notch, and a torsion spring sleeved on the rotating shaft between the mounting rod and the notch. The two ends of the torsion spring are fixed to the side wall of the mounting rod and the inner wall of the notch, respectively. A retaining member is provided in the notch to resist the mounting rod and maintain the distance between the clamping wheel and the annular connecting member. The annular convex edge is provided with an annular chamfer on the side near the circular plate that cooperates with the clamping wheel. The wheel surface of the clamping wheel on the side near the circular plate abuts against the side of the annular convex edge away from the circular plate.

[0006] By adopting the above technical solution, when connecting two pipe bodies, the worker only needs to insert the pipe body with the ring-shaped connector into the connecting ring. During this process, the annular chamfer of the annular convex edge abuts against the wheel surface of the clamping wheel and drives the mounting rod to rotate around the rotation axis between the mounting rod and the notch. The torsion spring undergoes adaptive deformation. When the two pipe bodies abut against each other at their closest ends, the wheel surface of the clamping wheel on the side closer to the circular plate abuts against the side of the annular convex edge away from the circular plate. The cooperation of multiple clamping wheels ensures the stability of the connection between the two pipe bodies.

[0007] Furthermore, the retaining member is a plate-shaped structure with a right-angled trapezoidal cross-section. The side of the retaining member away from the circular plate is an inclined surface that cooperates with the mounting rod. The mounting rod is pressed against the inclined surface of the retaining member under the action of the torsion spring. The distance between the wheel surface of the pressure wheel and the outer wall of the annular connecting member is greater than 0.

[0008] By adopting the above technical solution, it is ensured that when the workers insert the pipe body with the ring-shaped connector into the connecting ring, the annular chamfer on the annular convex edge can be smoothly driven by the clamping wheel to rotate the installation rod. Finally, the clamping wheel is reset under the torque of the torsion spring and keeps it pressed against the side of the annular convex edge away from the circular plate to maintain the stability of the connection between the two pipe bodies.

[0009] Furthermore, the surface of the annular connector away from the circular plate is a plane and perpendicular to the axis of the pipe body.

[0010] By adopting the above technical solution, the stability of the connection between the pressure roller and the annular flange is ensured.

[0011] Furthermore, a first annular groove is provided on the side of the circular plate near the annular protrusion, and a second annular groove that mates with the first annular groove is provided on the pipe body near the annular connector. An annular sealing ring is installed in both the first and second annular grooves.

[0012] By adopting the above technical solution, after the two pipe bodies are connected at their closest ends, under the action of the clamping wheel, the inner wall of the first annular groove and the inner wall of the second annular groove cooperate and press against the annular sealing ring, thus maintaining the sealing of the connection between the two pipe bodies.

[0013] Furthermore, the circular plate body is provided with a plurality of recessed grooves communicating with the first annular groove, and an adhesive layer is provided between the first annular groove and the annular sealing ring.

[0014] By adopting the above technical solution, the recessed groove increases the area of ​​the adhesive used to bond the first annular groove and the annular sealing ring, thereby enhancing the effect of the adhesive layer in bonding and fixing the annular sealing ring.

[0015] Furthermore, an anti-slip rubber ring is fixedly fitted on the side of the outer wall of the annular connector away from the circular plate.

[0016] By adopting the above technical solution, the anti-slip rubber ring is made of rubber material, which has a large coefficient of friction, ensuring the friction between the worker's hand and the ring-shaped connector, and reducing the probability of slippage when pushing the main body of the pipe through the ring-shaped connector.

[0017] Furthermore, the cross-section of the outer side of the anti-slip rubber ring is continuously corrugated, and the thickness of the middle part of the anti-slip rubber ring is less than the thickness of the two ends of the anti-slip rubber ring.

[0018] By adopting the above technical solutions, the anti-slip effect is further guaranteed.

[0019] Furthermore, two symmetrically arranged handles are fixed on the outer wall of the pipe body on the side away from the annular connector.

[0020] By adopting the above technical solution, during the process of inserting the pipe body with the ring-shaped connector into the connecting ring, the worker holds the handle with one hand and the anti-slip rubber ring with the other hand and pushes it, so that the pipe body with the ring-shaped connector can be inserted into the connecting ring, ensuring the installation process and reducing the probability of slippage.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This application changes the traditional method of connecting two pipes using multiple bolts and nuts, thus improving assembly and disassembly efficiency;

[0023] 2. In this application, when connecting two pipe bodies, the worker only needs to insert the pipe body with the annular connector into the connecting ring. During this process, the annular chamfer of the annular convex edge abuts against the wheel surface of the clamping wheel and drives the mounting rod to rotate around the rotation axis between the mounting rod and the notch. The torsion spring undergoes adaptive deformation. When the two pipe bodies abut against each other at their closest ends, the wheel surface of the clamping wheel on the side closer to the circular plate abuts against the side of the annular convex edge away from the circular plate. The cooperation of multiple clamping wheels ensures the stability of the connection between the two pipe bodies. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-4 As shown in the embodiment of this application, a municipal water supply and drainage pipeline connection structure is disclosed, including a connecting ring 2 sleeved on two pipeline bodies 1 to be connected. One end of one pipeline body 1 is fixedly fitted with a circular plate 3. The inner surface of the connecting ring 2 is fitted and fixed to the arc surface of the circular plate 3. An annular connector 4 is integrally formed on the outer wall of the other pipeline body 1 near the end of the pipeline body 1. An annular flange 41 is provided on the outer side of the annular connector 4. The cross-section of the annular flange 41 is quadrilateral. A notch 21 is provided at the intersection between the end of the connecting ring 2 away from the circular plate 3 and the outer wall of the connecting ring 2. Multiple notches 21 are provided and are evenly distributed about the axis of the connecting ring 2. Each notch 21 contains a... An elastic fixing component 5 is provided. The elastic fixing component 5 includes a mounting rod 51 rotatably installed in the notch 21, a clamping wheel 52 rotatably connected to the end of the mounting rod 51 away from the notch 21, and a torsion spring 53 sleeved on the rotating shaft between the mounting rod 51 and the notch 21. The two ends of the torsion spring 53 are fixed to the side wall of the mounting rod 51 and the inner wall of the notch 21, respectively. A retaining member 6 is provided in the notch 21 to block the mounting rod 51 and maintain the distance between the clamping wheel 52 and the annular connecting member 4. An annular chamfer 411 that cooperates with the clamping wheel 52 is provided on the side of the annular convex edge 41 near the circular plate 3. The wheel surface of the clamping wheel 52 on the side near the circular plate 3 abuts against the side of the annular convex edge 41 away from the circular plate 3.

[0031] When connecting two pipe bodies 1, the worker only needs to insert the pipe body 1 with the annular connector 4 into the connecting ring 2. During this process, the annular chamfer 411 of the annular convex edge 41 abuts against the wheel surface of the clamping wheel 52 and drives the mounting rod 51 to rotate around the rotation axis between the mounting rod 51 and the notch 21. The torsion spring 53 undergoes adaptive deformation. When the ends of the two pipe bodies 1 that are close to each other abut against each other, the wheel surface of the clamping wheel 52 on the side close to the circular plate 3 abuts against the side of the annular convex edge 41 away from the circular plate 3. The multiple clamping wheels 52 work together to ensure the stability of the connection between the two pipe bodies 1.

[0032] The retainer 6 is a plate-shaped structure with a right-angled trapezoidal cross-section. The side of the retainer 6 away from the circular plate 3 is an inclined surface that cooperates with the mounting rod 51. Under the action of the torsion spring 53, the mounting rod 51 abuts against the inclined surface of the retainer 6. The distance between the wheel surface of the pressure wheel 52 and the outer wall of the annular connecting member 4 is greater than 0.

[0033] This ensures that during the process of inserting the pipe body 1 with the annular connector 4 into the connecting ring 2, the annular chamfer 411 on the annular convex edge 41 can be smoothly driven by the clamping wheel 52 to rotate the mounting rod 51. Finally, the clamping wheel 52 is reset under the torque of the torsion spring 53 and remains pressed against the side of the annular convex edge 41 away from the circular plate 3, so as to maintain the stability of the connection between the two pipe bodies 1.

[0034] To ensure the stability of the connection between the clamping wheel 52 and the annular flange 41, the surface of the annular connector 4 away from the circular plate 3 is flat and perpendicular to the axis of the pipe body 1.

[0035] A first annular groove 31 is provided on the side of the circular plate 3 near the annular protrusion 41. A second annular groove 7, which mates with the first annular groove 31, is provided on the pipe body 1 near the annular connector 4. An annular sealing ring 8 is installed in both the first annular groove 31 and the second annular groove 7. After the two pipe bodies 1 are connected at their closest ends, under the action of the clamping wheel 52, the inner wall of the first annular groove 31 mates with the inner wall of the second annular groove 7 and abuts against the annular sealing ring 8, maintaining the sealing of the connection between the two pipe bodies 1.

[0036] The circular plate 3 has multiple recessed grooves 32 that communicate with the first annular groove 31. An adhesive layer 9 is provided between the first annular groove 31 and the annular sealing ring 8. The recessed grooves 32 increase the area for the adhesive used to bond the first annular groove 31 and the annular sealing ring 8, thereby enhancing the bonding and fixing effect of the adhesive layer 9 on the annular sealing ring 8.

[0037] An anti-slip rubber ring 10 is fixedly fitted on the side of the outer wall of the annular connector 4 away from the circular plate 3. The anti-slip rubber ring 10 is made of rubber material and has a large coefficient of friction, which ensures the friction between the worker's hand and the annular connector 4 and reduces the probability of slippage during the process of pushing the pipe body 1 through the annular connector 4 (so that the pipe body 1 with the annular connector 4 is inserted into the connecting ring 2).

[0038] To further ensure the anti-slip effect, the cross-section of the outer side of the anti-slip rubber ring 10 is continuously corrugated, the thickness of the middle part of the anti-slip rubber ring 10 is less than the thickness of the two ends of the anti-slip rubber ring 10, and two symmetrically arranged handles 11 are fixed on the outer wall of the pipe body 1 on the side away from the annular connector 4.

[0039] The working principle of a municipal water supply and drainage pipeline connection structure in this embodiment is as follows: When connecting two pipeline bodies 1, the worker only needs to insert the pipeline body 1 with the annular connector 4 into the connecting ring 2. During this process, the annular chamfer 411 of the annular convex edge 41 abuts against the wheel surface of the clamping wheel 52 and drives the mounting rod 51 to rotate around the rotation axis between the mounting rod 51 and the notch 21. The torsion spring 53 undergoes adaptive deformation. When the ends of the two pipeline bodies 1 that are close to each other abut against each other, the wheel surface of the clamping wheel 52 on the side close to the circular plate 3 abuts against the side of the annular convex edge 41 away from the circular plate 3. The multiple clamping wheels 52 work together to ensure the stability of the connection between the two pipeline bodies 1.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
