Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline connection, and in particular relates to a connection structure for preventing leakage of municipal drainage pipelines. Background Art
[0002] In modern urban infrastructure, drainage pipe systems are an important part of maintaining the normal operation of cities. These pipes are used to collect and transport domestic sewage, rainwater, industrial wastewater, etc., to ensure urban environmental sanitation and flood prevention safety. However, due to various factors such as aging of pipe materials, geological changes, corrosion, poor installation quality or loose joints, drainage pipes may leak, which not only leads to waste of water resources, but also may pollute the surrounding environment.
[0003] Traditional water supply and drainage pipe connection methods, such as flange connection and welding, are easy to operate and relatively low in cost, but they have some disadvantages that cannot be ignored. These connection methods can usually only achieve a one-time sealing of the pipe, and are difficult to adapt to long-term use requirements and complex geological environments. Utility Model Content
[0004] The purpose of the utility model is to provide a connection structure for preventing leakage of municipal drainage pipes in order to solve the above-mentioned technical problems, so as to improve the sealing performance between water pipes and facilitate disassembly by operators.
[0005] In view of this, the utility model provides a connection structure for preventing leakage of municipal drainage pipes, which is characterized by comprising:
[0006] A connecting pipe, wherein both ends of the connecting pipe are provided with extension pipes, the diameter of the extension pipes is smaller than the diameter of the connecting pipe, and the extension pipes are connected to the connecting pipe;
[0007] Drain pipes, two of which are provided and are respectively sleeved on the extension pipes at both ends of the connecting pipe;
[0008] A locking mechanism, which is sleeved on the extension pipe and can clamp the drain pipe in cooperation with the extension pipe;
[0009] Wherein, a sealing structure is arranged between the locking mechanism and the outer wall of the extension tube.
[0010] In the technical solution, after the drain pipe is sleeved on the extension pipe, the locking mechanism cooperates with the extension pipe to ensure that sufficient pressure is formed between the extension pipe and the inner wall of the drain pipe, thereby ensuring the stability of the connection and the ability to prevent leakage. The provided locking mechanism can facilitate maintenance personnel to connect and fix the drain pipe and the extension pipe to improve the efficiency of maintenance. The sealing structure provided between the locking mechanism and the outer wall of the drain pipe can increase the pressure between the sealing structure and the outer wall of the drain pipe during the locking process of the locking mechanism, which can further improve the anti-leakage property of the connection structure.
[0011] In the above technical solution, further, the locking drum includes:
[0012] A locking sleeve, which is sleeved on the extension pipe and has a cavity between it and the connecting pipe, and the cavity is used to accommodate the drainage pipe;
[0013] A locking thread, which is arranged on the outer wall of the locking sleeve and extends inwardly to the outer wall of the connecting pipe;
[0014] A locking handle, which is rotatably disposed on the locking sleeve and cooperates with the locking thread;
[0015] The air avoidance grooves are evenly distributed in the circumferential direction at the front end of the locking sleeve, so that a plurality of claws that can be opened are formed at the front end of the locking sleeve.
[0016] In the present technical solution, the drain pipe is sleeved in the cavity between the locking sleeve and the extension pipe, and when the drain pipe is installed, the claw can be slightly opened. After the drain pipe is installed in place, the claw can be simultaneously contracted by rotating the locking handle, thereby achieving the locking of the drain pipe, and by extending the thread to the outer wall of the connecting pipe, the locking handle can be moved outward from the connecting pipe, which facilitates the tightening of the claw and improves the efficiency of installation.
[0017] In the above technical solution, further, a positioning structure is provided between the locking sleeve and the extension tube.
[0018] In the above technical solution, further, the positioning structure includes:
[0019] A card block, which is arranged at the connection between the extension tube and the connecting tube, and a card slot is arranged at the corresponding position of the locking sleeve, and the shape of the card slot matches the shape of the card block;
[0020] A locking bolt passes through the locking sleeve and is threadedly connected to the clamping block.
[0021] In the present technical solution, by cooperating between the provided clamping block and the clamping groove, it can ensure that the locking sleeve is correctly sleeved on the extension tube, avoiding misalignment of the locking threads on the outer wall of the connecting tube and the outer wall of the locking sleeve, which is beneficial to improving the stability of the connection structure.
[0022] In the above technical solution, further, the sealing structure includes:
[0023] A sealing groove, wherein the sealing groove is arranged on the inner wall of the locking sleeve;
[0024] A rubber ring is arranged in the sealing groove, and the inner wall of the rubber ring contacts the outer wall of the drain pipe.
[0025] In the present technical solution, by cooperating between the sealing groove and the rubber ring, the contact pressure between the rubber ring and the outer wall of the drain pipe can be increased when the claw part contracts, which is beneficial to improve the sealing between the drain pipe and the extension pipe and avoid leakage of the drain pipe.
[0026] In the above technical solution, further, an anti-loosening structure is provided between the locking handle and the outer wall of the connecting pipe.
[0027] In the above technical solution, further, the anti-loosening structure includes:
[0028] An ear plate, wherein the ear plate is diagonally fixed on the outer wall of the connecting pipe;
[0029] A limiting rod, wherein the limiting rod passes through the locking handle and the ear plate, and locking nuts are threadedly arranged at both ends of the limiting rod.
[0030] In the present technical solution, the cooperation among the ear plate, the limit rod and the locking nut can prevent the locking handle from loosening after long-term use, which is beneficial to improving the stability of the connection structure.
[0031] In the above technical solution, further, the locking sleeve, locking handle and connecting pipe are all made of stainless steel.
[0032] In the present technical solution, by setting the material of the locking sleeve, the locking handle, and the connecting pipe to stainless steel, the service life of the connecting structure can be increased.
[0033] In the above technical solution, further, an anti-slip structure is provided on the outer side of the locking handle.
[0034] In this technical solution, the anti-slip structure makes it easier for maintenance personnel to turn the locking handle, thereby improving installation efficiency.
[0035] The beneficial effects of the utility model are:
[0036] 1. After the drain pipe is sleeved on the extension pipe, the locking mechanism cooperates with the extension pipe to ensure that sufficient pressure is formed between the extension pipe and the inner wall of the drain pipe, thereby ensuring the stability of the connection and the ability to prevent leakage. The locking mechanism is also convenient for maintenance personnel to connect and fix the drain pipe and the extension pipe to improve the efficiency of maintenance. The sealing structure provided between the locking mechanism and the outer wall of the drain pipe can increase the pressure between the sealing structure and the outer wall of the drain pipe during the locking process of the locking mechanism, which can further improve the anti-leakage performance of the connection structure.
[0037] 2. Through the cooperation between the provided clamping block and the clamping groove, it can be ensured that the locking sleeve is correctly sleeved on the extension tube, avoiding the misalignment of the locking threads on the outer wall of the connecting tube and the outer wall of the locking sleeve, which is beneficial to improving the stability of the connection structure.
