Description

Technical Field

[0001] This utility model relates to the field of emergency water supply pipeline equipment technology, specifically an emergency water supply pipeline quick connection device. Background Technology

[0002] Urban water supply security is crucial to the national water security strategy and the daily lives of residents. In the event of sudden extreme disasters such as earthquakes and floods, urban water supply systems face severe challenges, with some areas potentially losing their automatic water supply function. Buildings and residential communities, as the last mile of urban water supply, bear the responsibility of ensuring the basic water needs of urban residents. Building and community water supply systems encompass both outdoor and indoor water supply networks, while secondary water supply pump stations connecting the two serve to boost pressure and improve efficiency in the indoor water supply system. Currently, many types of mobile emergency water supply equipment exist on the market, such as emergency water supply vehicles and emergency water pumps. These facilities alleviate urban pressure caused by temporary water demand. Because these interfaces need to be permanently installed in buildings or communities, and there are time constraints during emergencies, they not only need stable connections but also quick installation and disassembly.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a quick connection device for emergency water supply pipelines, which solves the problems mentioned in the background art.

[0005] Technical solution To achieve the above objectives, this utility model is implemented through the following technical solution: an emergency water supply pipeline quick connection device, including a first pipeline and a connecting pipeline, wherein the first pipeline has a clamp and a groove at its end, a rotating handle is rotatably connected to the first pipeline, the connecting pipeline has a slot at its end corresponding to the first pipeline, a fixing plate is fixedly provided at the other end of the connecting pipeline, and a limiting structure is provided on the connecting pipeline, the limiting structure abutting against the fixing plate.

[0006] Preferably, the limiting structure includes a limiting plate, a magnetic block, a fixing block, and a spring. The bottom of the rotating handle is fixed with a clip and a block. The width of the rotating handle is the same as the width of the slot. The fixing block is fixed to the connecting pipe.

[0007] Preferably, springs are fixed on both sides of the fixing block, and the other end of the springs is fixedly connected to the inner wall of the limiting plate. Two magnetic blocks are provided above the fixing block, and magnetic blocks are also fixed on the upper ends of the two limiting plates respectively.

[0008] Preferably, the magnetic block on the limiting plate corresponds to the magnetic block on the fixing block and is the same size. The card and slot are provided with limiting grooves on both side walls, and the size of the limiting grooves is larger than the size of the limiting plate.

[0009] Preferably, the first pipe is provided with a rubber ring inside. Beneficial effects

[0010] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a quick connection device for emergency water supply pipelines. After connecting the first pipeline to the connecting pipeline, the two are connected to the bottom. The handle is rotated through the empty groove, and then the handle is turned upward. At this time, the card and block are located in the ring groove. Then the two magnetic blocks are separated. At this time, the elastic potential energy of the spring is released and the limiting plate is locked into the limiting groove, further completing the fixed limiting between the two pipelines.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1-4 As shown: A quick connection device for emergency water supply pipeline includes a first pipeline 1 and a connecting pipeline 2. The first pipeline 1 has a clamp and groove 4 at one end. A rotating handle 3 is rotatably connected to the first pipeline 1. The connecting pipeline 2 has a slot 5 at the end corresponding to the first pipeline 1. A fixing plate is fixed at the other end of the connecting pipeline 2. A limiting structure is provided on the connecting pipeline 2, and the limiting structure abuts against the fixing plate.

[0015] The limiting structure includes a limiting plate 6, a magnetic block 10, a fixing block 11, and a spring 12. A clip and a block 7 are fixed at the bottom of the rotating handle 3. The width of the rotating handle 3 is the same as the width of the empty groove 5. In the initial state, the handle of the rotating handle 3 faces the tail end of the first pipe 1. When connecting the first pipe 1 and the connecting pipe 2, the rotating handle 3 can pass through the empty groove 5 and fall into the annular groove 9. After connecting the first pipe 1 and the connecting pipe 2, the rotating handle 3 is turned upward so that the clip and block 7 fall into the annular groove 9. The clip and block 7 are made of rubber and have a large friction force, which can further limit the fixed connection of the two pipes. When separating the two, the rotating handle 3 is turned backward so that the clip and block 7 leave the annular groove 9. Then the magnetic block 10 is pulled until the two magnetic blocks 10 attract each other. At this time, the limiting plate 6 leaves the limiting groove 8, and the two pipes can be pulled apart. The fixing block 11 is fixed on the connecting pipe 2.

[0016] The working principle of the limiting structure is as follows: In the initial state, the magnetic blocks 10 on the two limiting plates 6 and the magnetic blocks 10 on the fixing block 11 attract each other, and the limiting plates 6 are tightly attached to the two side walls of the fixing block 11. When the first pipe 1 is connected to the connecting pipe 2, the two magnetic blocks 10 are separated by hand, and the spring 12 that was originally squeezed relaxes and pushes the limiting plates 6 open. At this time, the two limiting plates 6 are pushed into the limiting groove 8, which conveniently realizes the fixing and can meet the emergency time limit requirements.

[0017] Springs 12 are fixed on both sides of the fixing block 11. The other end of the springs 12 is fixedly connected to the inner wall of the limiting plate 6. Two magnetic blocks 10 are provided above the fixing block 11. Magnetic blocks 10 are also fixed on the upper ends of the two limiting plates 6. The magnetic blocks 10 on the fixing block 11 and the magnetic blocks 10 on the limiting plate 6 attract each other. The width of the magnetic blocks 10 is smaller than the width of the limiting plate 6, so that when part of the limiting plate 6 is pushed into the limiting groove 8, there will be no resistance.

[0018] The magnetic block 10 on the limiting plate 6 is positioned and the magnetic block 10 on the fixing block 11 are the same size and correspond to each other. The card and slot 4 are provided with limiting grooves 8 on both sides, and the size of the limiting grooves 8 is larger than that of the limiting plate 6.

[0019] The first pipe 1 has a rubber soft ring inside, which is used to better lock the two pipes together. At the same time, it can play a buffering role when water flows through, preventing the two pipes from being damaged due to excessive impact.

[0020] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
