Abstract
Description
Technical Field
[0001] This utility model belongs to the field of reinforced concrete technology, and in particular relates to a connection structure for reinforced concrete steel socket pipes. Background Technology
[0002] The connection structure of reinforced concrete steel socket pipes mainly achieves a stable connection between pipe sections through the precise matching of prefabricated steel sockets and spigots. The spigot end is embedded inside the socket, while ensuring that the interface maintains the integrity of the structure when subjected to internal pressure or external loads. This achieves high water tightness, resistance to foundation settlement and corrosion resistance, and is widely used in underground pipeline projects such as drainage and water supply.
[0003] Traditional reinforced concrete steel socket pipe connection structures have many limitations. During the connection process, there is a lack of buffer devices, and the impact force during rigid pipe connection is large, which can easily lead to cracks or damage at the connection, affecting the overall structural stability. The installation process is cumbersome, requiring a large number of tools for manual calibration and fixing, which consumes a lot of time and manpower, resulting in low construction efficiency. Disassembly is extremely inconvenient, and often requires the use of force to forcibly separate the pipes, which not only easily causes secondary damage to the pipes, but also increases maintenance costs and difficulty. It is difficult to meet the needs of modern engineering for efficient, convenient and reliable connections.
[0004] To address these issues, we provide a reinforced concrete steel socket pipe connection structure. Utility Model Content
[0005] The purpose of this utility model is to provide a connection structure for reinforced concrete steel socket pipes. Through the cooperation of the first connector, the second connector and the self-locking mechanism, it solves the problems of easy damage to the connection and inconvenience of disassembly caused by rigid connection in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a connection structure for reinforced concrete steel socket pipes, comprising a first connector, a second connector for use with the first connector being inserted into one side of the first connector, and a self-locking mechanism between the first and second connectors; a support plate is fixedly connected to the inner wall of both the first and second connectors, a connecting pipe is inserted through one side of the support plate, and a first spring is sleeved on the surface of the connecting pipe, one end of the first spring being fixedly connected to the support plate, and the other end of the first spring being fixedly connected to the connecting pipe; an isolation block is fixedly connected to the inner wall of both the first and second connectors, and the inner wall of the isolation block is slidably connected to the connecting pipe; the self-locking mechanism includes a movable sleeve sleeved on the first connector, an annular groove is formed on the surface of the first connector, and the second spring is disposed in the cavity of the annular groove. One end of the second spring is fixedly connected to the inner wall of the annular groove, and the other end of the second spring is fixedly connected to the movable sleeve. The inner wall of the annular groove is provided with evenly distributed through grooves. The second connector is provided with a limiting groove. A magnetic self-locking ball is provided in the inner cavity of the limiting groove. The top of the magnetic self-locking ball extends into the inner cavity of the through groove. The first connector and the second connector are inserted into each other to form the basic structure of the pipe connection. The support plate on the inner wall is used to fix the connecting pipe. The first spring is sleeved on the outside of the connecting pipe to provide elastic support so that the connecting pipe can move in a buffered manner when subjected to force. The isolation block plays a sliding limiting and guiding role for the connecting pipe. The movable sleeve is connected to the annular groove of the first connector through the second spring. The magnetic self-locking ball is set in the limiting groove of the second connector. When the movable sleeve moves, the magnetic self-locking ball can be embedded in the through groove of the annular groove to achieve self-locking.
[0008] The present invention is further configured such that a movable rod is fixedly connected to one side of the top of the movable sleeve, and the surface of the movable rod is provided with anti-slip texture. The movable rod at the top of the movable sleeve facilitates the operator to manually move the movable sleeve, and the anti-slip texture on the surface can increase the friction between the hand and the movable rod to prevent slipping during operation.
[0009] The present invention is further configured such that a sealing filler is provided between the isolation block and the connecting pipe, and a moving groove is provided on the surface of the support plate to cooperate with the movement of the connecting pipe. The sealing filler between the isolation block and the connecting pipe is used to fill the gap and enhance the sealing of the connection. The moving groove on the surface of the support plate provides space for the movement of the connecting pipe, ensuring that the connecting pipe can freely extend and retract under the action of the first spring.
[0010] The present invention is further configured such that a steel socket pipe body is provided in the inner cavity of the opposite end of the first connector and the second connector, and a fastening mechanism is provided on the surface of the opposite end of the first connector and the second connector. The inner cavities of the first connector and the second connector are used to install the steel socket pipe body to realize the connection of the pipeline. The fastening mechanism on the surface of the two ends is used to further fix the steel socket pipe body and prevent it from loosening in the connector.
[0011] The present invention is further configured such that the fastening mechanism includes a connecting buckle, a fastening ring is movably connected to the top of the connecting buckle via a rotating rod, a connecting ring is fixedly connected to the bottom of the connecting buckle, a fastener is movably connected to the other end of the connecting ring, a rotating plate is movably connected to one end of the fastening ring via a rotating rod, a buckle is fixedly connected to the top of the rotating plate, and a lever is fixedly connected to the top of the rotating plate. The connecting buckle, fastening ring, connecting ring, fastener, rotating plate, and lever of the fastening mechanism cooperate with each other. By rotating the lever, the rotating plate is driven to tighten or loosen the fastening ring, thereby achieving the fastening or disassembly of the steel socket pipe body.
[0012] The present invention is further configured such that a sealing groove is provided on the opposite side of the connecting pipe, and a sealing ring is provided in the inner cavity of the sealing groove. The sealing ring is made of wear-resistant and corrosion-resistant polytetrafluoroethylene resin. The sealing groove on the opposite side of the connecting pipe is used to install the sealing ring. The sealing ring made of wear-resistant and corrosion-resistant polytetrafluoroethylene resin can fill the gap between the connecting pipes and enhance the sealing and corrosion resistance of the connection.
[0013] The present invention has the following beneficial effects.
[0014] 1. In this utility model, after the two steel socket pipe bodies are inserted into the corresponding connectors, the moving sleeve is pushed to compress the second spring, causing the connecting pipes to move towards each other to complete the connection. During the connection process, the connecting pipes slide on the inner wall of the isolation block, and the support plate compresses the first spring, effectively buffering the connection impact force. This not only ensures the stability and smoothness of the installation process, but also enhances the stability of the connection structure by providing continuous elastic support. At the same time, the disassembly process of the steel socket pipe bodies is more convenient and efficient. By pushing the moving sleeve in the opposite direction to release the pressure of the first spring, the connecting pipes can be easily separated. This ensures both the stability and smoothness of the installation process and the convenience of subsequent maintenance and disassembly.
[0015] 2. This utility model pushes the movable sleeve to slide and compress the second spring in the annular groove, driving the connecting pipe to move. When the connecting pipe is fully connected, the connecting pipe in the second connector compresses the magnetic self-locking ball, causing it to fall precisely into the limiting groove. This process does not require additional fixing steps. With the dual protection of magnetic force and mechanical limiting, automatic locking is achieved. The ingenious cooperation between the magnetic self-locking ball, the through groove, and the limiting groove automatically engages to form a mechanical limit at the moment the connection is completed, strongly resisting the risk of falling off due to external force during use. This simplifies the operation process and greatly improves construction efficiency and connection safety. Attached Figure Description
