Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, specifically a quick connector for a waste liquid collection pipe. Background Technology
[0002] Waste liquid is easily generated during the dismantling of scrapped cars. In order to collect and drain the waste liquid, waste liquid collection pipes are needed for collection and drainage treatment. The sealing and convenience of the connection between the pipes directly affect the waste liquid treatment efficiency and environmental safety.
[0003] In the application document for a sealing structure of a water supply pipe joint with application number 202422605090.9, one end of the sealing gasket is conical. During the installation of joint A and joint B, joint B can push the sealing gasket to fold. The folded sealing gasket can be compressed by several protrusions A and B to form multiple sealing points, which improves the overall sealing performance. Protrusions A and B are always tightly pressed against the sealing gasket. When the water pressure suddenly increases or during long-term use, water is unlikely to break through multiple sealing points and cause overflow. Moreover, the overall installation is convenient and quick, and the sealing performance is good.
[0004] While the above applications meet the user's needs to a certain extent, certain defects still exist during use. Specific problems are as follows: When using bolted connections, multiple bolts need to be tightened one by one, which is cumbersome and time-consuming, especially in scenarios where frequent disassembly and replacement of pipelines are required, seriously affecting work efficiency. Although welded connections can ensure high sealing performance, they are permanent connections and cannot be disassembled and reused. When the pipeline needs repair or replacement, the original welded structure must be destroyed, increasing maintenance costs and workload. In addition, some existing quick couplings have simple structures and rely on only a single sealing method, which can easily lead to sealing failure when transporting corrosive or high-pressure waste liquids. Based on this, this utility model designs a quick coupling for waste liquid collection pipes to solve the above problems. Utility Model Content
[0005] This utility model provides a quick connector for waste liquid collection pipes, which can effectively solve the problems mentioned in the background art. When using bolted connections, multiple bolts need to be tightened one by one, which is cumbersome and time-consuming. This is especially true in scenarios where frequent disassembly and replacement of pipelines are required, which seriously affects work efficiency. Although welded connections can ensure high sealing performance, they are permanent connections and cannot be disassembled and reused. When the pipeline needs to be repaired or replaced, the original welded structure must be destroyed, which increases maintenance costs and workload. In addition, some existing quick connectors have simple structures and rely on only a single sealing method. When transporting corrosive or high-pressure waste liquids, the sealing is prone to failure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick connector for a waste liquid collection pipe, comprising a first pipe and a second pipe, wherein the first pipe and the second pipe are connected by a threaded cylinder and a fixed cylinder, wherein a rotatable rotating rod is provided at the top of the fixed cylinder, and a pressing rod for pressing the threaded cylinder is provided at one end of the rotating rod, wherein a rubber ring driven by the threaded cylinder is provided inside the fixed cylinder, and the pressing rod is rotated by the movement of the rubber ring.
[0007] A quick connector for a waste liquid collection pipe, preferably, has a fixed sleeve fixedly sleeved on the outer side of one end of the first pipe, and a threaded sleeve rotatably connected to the outer side of one end of the second pipe, wherein the threaded sleeve and the fixed sleeve are connected by threads.
[0008] A quick connector for a waste liquid collection pipe, preferably, has a compression spring uniformly welded to one end of the fixed cylinder, a movable plate welded to one end of the compression spring, a limit post installed at one end of the movable plate by screws, a rubber ring slidably connected inside the fixed cylinder, and the rubber ring and the limit post being bonded together.
[0009] A quick connector for a waste liquid collection pipe, preferably, has a rotating shaft uniformly rotatably connected to the outside of the second pipe, a return spring welded to one end of the rotating shaft, a rotating rod fixedly sleeved on the outside of the rotating shaft, a pressing rod welded to one end of the rotating rod, and a rubber plate adhered to one end of the pressing rod.
[0010] A quick connector for a waste liquid collection pipe, preferably wherein the movable plate is located at the bottom of one end of the rotating rod, and the limiting post penetrates the fixed cylinder.
[0011] A quick connector for a waste liquid collection pipe, preferably wherein the rubber plate is located outside the threaded cylinder, and the longitudinal section of the combination of multiple pressing rods is circular.
[0012] Compared with existing technologies, the advantages of this utility model are as follows: The structure of this utility model is scientifically sound and reasonable, and it is safe and convenient to use. The threaded connection between the threaded cylinder and the fixed cylinder enables rapid connection between the first and second pipes without the need for complex tools; the connection can be completed simply by rotating the threaded cylinder, greatly simplifying the operation process. Compared with traditional bolt and welding connections, it significantly improves pipe connection efficiency, and is especially suitable for scenarios requiring frequent pipe disassembly and replacement. During the connection process, the threaded cylinder pushes the rubber ring to move, and at the same time, through mechanical linkage, the pressing rod drives the rubber plate to make tight contact with the outside of the threaded cylinder, forming a double sealing structure of the rubber ring and the rubber plate. This double sealing can effectively prevent waste liquid leakage, reduce environmental pollution and safety risks. The double fixing method, which combines threaded connection and compression fixing, can effectively prevent the pipeline from loosening due to factors such as vibration and pressure changes during use, and ensure the long-term stability of the connection.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: a quick connector for a waste liquid collection pipe, including a first pipe 1 and a second pipe 2. A fixed cylinder 4 is fixedly sleeved on the outer side of one end of the first pipe 1. A threaded cylinder 3 is rotatably connected to the outer side of one end of the second pipe 2. A compression spring 5 is uniformly welded to one end of the fixed cylinder 4. A movable plate 6 is welded to one end of the compression spring 5. A limit post 7 is installed on one end of the movable plate 6 by screws. A rubber ring 8 is slidably connected inside the fixed cylinder 4. The rubber ring 8 is bonded to the limit post 7. A rotating shaft 10 is uniformly rotatably connected to the outer side of the second pipe 2. A return spring 9 is welded to one end of the rotating shaft 10. One end of the return spring 9 is welded to the top of the fixed cylinder 4. A rotating rod 11 is fixedly sleeved on the outer side of the rotating shaft 10. A pressing rod 12 is welded to one end of the rotating rod 11. A rubber plate 13 is bonded to one end of the pressing rod 12.
[0017] The threaded cylinder 3 and the fixed cylinder 4 are connected by threads, which facilitates the connection of the first pipe 1 and the second pipe 2.
[0018] The movable plate 6 is located at the bottom of one end of the rotating rod 11, and the limiting post 7 passes through the fixed cylinder 4, which facilitates the support of the bottom of the rotating rod 11 and squeezes the rotating rod 11 to push the pressing rod 12 to move.
[0019] The rubber plate 13 is located outside the threaded cylinder 3. The longitudinal section of the multiple pressing rods 12 is circular after combination, which enhances the sealing between the threaded cylinder 3 and the fixed cylinder 4.
[0020] After aligning the first pipe 1 and the second pipe 2, the operator rotates the threaded cylinder 3, connecting it to the fixed cylinder 4 via a threaded connection. As the threaded cylinder 3 moves inside the fixed cylinder 4, it pushes the rubber ring 8, which in turn moves the limiting post 7, which in turn moves the moving plate 6. The movement of the moving plate 6 then drives the rotating rod 11 to rotate, which in turn drives the pressing rod 12 and the rubber plate 13 to rotate, bringing the rubber plate 13 into contact with the outside of the threaded cylinder 3. This double seal of the rubber ring 8 and the rubber plate 13 enhances the sealing performance of the connected first pipe 1 and second pipe 2, preventing leakage. It also facilitates the connection of the first pipe 1 and second pipe 2, eliminating the need for bolts or welding in modern construction, thus improving the connection efficiency. Furthermore, the double fixation of the threaded connection and compression ensures the stability of the connected first pipe 1 and second pipe 2.
[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
