Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene water supply pipes, in particular to a polyethylene water supply pipe which is easy to connect. Background Art

[0002] PE materials are widely used in the field of water supply pipe manufacturing due to their high strength, corrosion resistance, and non-toxicity. Polyethylene is a non-inert material. Except for a small amount of strong oxidants, it can withstand corrosion from a variety of chemicals and is not easy to breed bacteria. It is well known that the reason why steel pipes and cast iron pipes are replaced by plastic pipes is not only because plastic pipes have lower energy consumption for water transmission, lower energy consumption for life, lighter weight, less water flow resistance, easier and faster installation, lower cost, longer life, and heat preservation, but also because plastic pipes are better than steel pipes and cast iron pipes in corrosion resistance and not easy to breed microorganisms.

[0003] The common water supply pipes on the market may have the problem of insufficient length when in use, so the water supply pipes need to be spliced. At present, the water supply pipes are generally connected by welding. If the pipes are large, they need to be heated manually. Therefore, this connection method is more challenging for the workers' skills. If the welding temperature and the uniformity of heating are not well controlled, it is easy to cause an unstable connection. These problems may affect the subsequent use of the water supply pipes. If a single pipe needs to be repaired or replaced later, it is not easy to separate the connected pipes if welding is used.

[0004] To this end, we propose a polyethylene water supply pipe that is easy to connect. Summary of the invention

[0005] The utility model aims to provide a polyethylene water supply pipe which is easy to connect, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polyethylene water supply pipe that is easy to connect, comprising a water supply pipe body, wherein the water supply pipe body has two, a mounting pipe is placed between the two water supply pipe bodies, a mounting assembly, wherein the mounting assembly has two groups, the two groups of mounting assemblies are installed on the left and right sides of the outer surface of the mounting pipe, and the mounting assembly is used to facilitate the connection of the two water supply pipe bodies for use; and a disassembly assembly, wherein the disassembly assembly is installed at one end close to the two groups of mounting assemblies, and the disassembly assembly is used to facilitate the separation of the two water supply pipe bodies for use.

[0007] Preferably, each group of the mounting components includes four mounting frames, and the four mounting frames are installed in a circular distribution with respect to the outer surface of the mounting tube. A slot is provided inside each of the mounting frames, and a block is clamped inside each of the slots. The outer surfaces of the two water supply pipe bodies are fixedly connected with fixing rings, and the position of each fixing ring corresponds to the position of the corresponding block, and two springs are fixedly connected between the top wall of each slot and the upper surface of the block.

[0008] Preferably, rubber strips are fixedly mounted on both left and right sides of the inner wall of the mounting tube.

[0009] Preferably, two rubber retaining rings are installed on the inner wall of the mounting tube, and the distance between the two rubber retaining rings and the left and right sides of the mounting tube is matched with the distance between the fixing ring and the left and right sides of the water supply pipe body.

[0010] Preferably, the disassembly assembly includes limit grooves, each of which is opened on the surface of the mounting frame, and a limit block is clamped inside each of the limit grooves. The upper surface of each block is fixedly connected to two mounting plates, and each group of mounting plates is rotatably connected with a rotating rod, and the position of each limit block corresponds to the position of the rotating rod.

[0011] Preferably, two rotating rings are threadedly connected between the outer surfaces of the mounting tube, and the two rotating rings are fixedly connected with top rings on the sides away from each other, and the position of each top ring is adapted to the position of the corresponding limit block.

[0012] Preferably, the two top rings have smooth surfaces on their sides facing away from each other.

[0013] Preferably, when the rotating rod is in a normal state, the inclined surface of the limit block is located below the rotating rod.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. When it is necessary to install the water supply pipe body, first forcefully insert the two water supply pipe bodies into the left and right ends of the installation pipe respectively. The rubber strip can be used to wrap the outer wall of the water supply pipe body. The rubber retaining ring can be used to easily control the insertion depth of the water supply pipe body and to seal the opening of the water supply pipe body to a certain extent. When the water supply pipe body is inserted into the installation pipe, the inclined surface of the block will first contact the fixing ring. At this time, the block will rise a part. When the fixing ring is in the empty groove of the block, the block will be subject to the elastic force of the spring. At this time, the fixing ring can be stuck into the empty groove of the block, thereby achieving the purpose of firmly fixing the position of the water supply pipe body.

[0016] Among them, when the staff needs to install the water supply pipe, the water supply pipe is quickly locked by the installation component during installation, thereby reducing the workload of the staff in installing the water supply pipe, thereby achieving a faster installation effect.

[0017] 2. When it is necessary to disassemble and overhaul a single water supply pipe body, first the staff only needs to rotate the rotating ring close to the water supply pipe body that needs to be overhauled. For example, the water supply pipe body on the left side needs to be overhauled. At this time, it is only necessary to rotate the rotating ring in the positive direction. Through the threaded connection between the rotating ring and the mounting pipe, the rotating ring on the left side can be moved to the left. At this time, the top ring will move to the left synchronously. The top ring will further squeeze the limit block, which will cause the limit block to be inserted under the rotating rod. At this time, when the limit block continues to move, the card block can be made to rise, and then the lock of the card block on the fixed ring can be released. The water supply pipe body can be dismantled and overhauled as a whole by force. After the water supply pipe body is pulled out, it is only necessary to rotate the rotating ring in the opposite direction. At this time, the top ring can be moved in the direction away from the limit block. The card block will drop due to the influence of the spring force. At this time, the rotating rod will drop to achieve the effect of automatically resetting the limit block. The overall operation is relatively convenient.

[0018] By setting up the disassembly assembly, the purpose of facilitating the disassembly and maintenance of a single water supply pipe body can be achieved, which solves the problem that it is difficult to separate the connected pipes when the pipes are currently connected by welding.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Embodiment 1

[0028] A polyethylene water supply pipe that is easy to connect includes a water supply pipe body 3, wherein the water supply pipe body 3 has two, a mounting pipe 4 is placed between the two water supply pipe bodies 3, a mounting assembly 1, wherein the mounting assembly 1 has two groups, the two groups of mounting assemblies 1 are installed on the left and right sides of the outer surface of the mounting pipe 4, and the mounting assembly 1 is used to facilitate the connection of the two water supply pipe bodies 3 for use, and a disassembly assembly 2, wherein the disassembly assembly 2 is installed at one end close to the two groups of mounting assemblies 1, and the disassembly assembly 2 is used to facilitate the separation of the two water supply pipe bodies 3 for use.

[0029] Each set of mounting components 1 includes four mounting frames 8, and the four mounting frames 8 are installed in a circular distribution about the outer surface of the mounting pipe 4. A slot 9 is provided inside each mounting frame 8, and a block 10 is clamped inside each slot 9. The outer surfaces of the two water supply pipe bodies 3 are fixedly connected with fixing rings 7, and the position of each fixing ring 7 corresponds to the position of the corresponding block 10. Two springs 11 are fixedly connected between the top wall of each slot 9 and the upper surface of the block 10.

[0030] Rubber strips 6 are fixedly installed on both the left and right sides of the inner wall of the installation pipe 4 to seal the gap between the outer surface of the water supply pipe body 3 and the inner wall of the installation pipe 4 .

[0031] Two rubber retaining rings 5 ​​are installed on the inner wall of the mounting tube 4. The distance between the two rubber retaining rings 5 ​​and the left and right sides of the mounting tube 4 matches the distance between the fixing ring 7 and the left and right sides of the water supply pipe body 3, which can facilitate the staff to grasp the depth of the water supply pipe body 3 inserted into the mounting tube 4.

[0032] When the water supply pipe body 3 needs to be installed, first, the two water supply pipe bodies 3 are forcefully inserted into the left and right ends of the installation tube 4 respectively. The rubber strip 6 can be used to wrap the outer wall of the water supply pipe body 3. The rubber retaining ring 5 can be used to easily control the insertion depth of the water supply pipe body 3 and to seal the opening of the water supply pipe body 3 to a certain extent. When the water supply pipe body 3 is inserted into the installation tube 4, the inclined surface of the block 10 will first contact the fixing ring 7. At this time, the block 10 will rise a part. When the fixing ring 7 is in the empty groove of the block 10, the block 10 will be subjected to the elastic force of the spring 11. At this time, the fixing ring 7 can be stuck into the empty groove of the block 10, thereby achieving the purpose of firmly fixing the position of the water supply pipe body 3.

[0033] By providing the installation assembly 1 , it is possible to facilitate the workers to install the water supply pipe body 3 as a whole, and further make it more convenient for the workers to install the water supply pipe body 3 .

[0034] Embodiment 2

[0035] The disassembly component 2 includes a limit groove 14, each of which is opened on the surface of the mounting frame 8, and a limit block 15 is clamped inside each limit groove 14. The upper surface of each clamping block 10 is fixedly connected to two mounting plates 12, and each group of mounting plates 12 is rotatably connected with a rotating rod 13, and the position of each limit block 15 corresponds to the position of the rotating rod 13.

[0036] Two rotating rings 16 are threadedly connected between the outer surfaces of the mounting tube 4 , and top rings 17 are fixedly connected to the sides of the two rotating rings 16 that are away from each other. The position of each top ring 17 is adapted to the position of the corresponding limit block 15 .

[0037] The two top rings 17 have smooth surfaces on their sides away from each other, so that the top rings 17 can move more smoothly when pushing the limit block 15.

[0038] When the rotating rod 13 is in the normal state, the inclined surface of the limit block 15 is below the rotating rod 13 , which can prevent the rotating rod 13 from rising or falling when the limit block 15 moves when the rotating rod 13 is below the limit block 15 .

[0039] When it is necessary to disassemble and overhaul a single water supply pipe body 3, first the staff only needs to rotate the rotating ring 16 close to the water supply pipe body 3 that needs to be overhauled. For example, the water supply pipe body 3 located on the left side needs to be overhauled. At this time, it is only necessary to rotate the rotating ring 16 in the positive direction. Through the threaded connection between the rotating ring 16 and the mounting tube 4, the rotating ring 16 located on the left side can be moved to the left. At this time, the top ring 17 will move to the left synchronously. Further, the top ring 17 will squeeze the limit block 15, which will cause the limit block 15 to be inserted into the rotating rod. 13, when the limit block 15 continues to move, the block 10 can be lifted up, and then the block 10 can release the lock on the fixing ring 7, and the water supply pipe body 3 can be dismantled and repaired as a whole by just using force. When the water supply pipe body 3 is pulled out, it is only necessary to rotate the rotating ring 16 in the opposite direction, and the top ring 17 can be moved away from the limit block 15 by the same logic. The block 10 will fall under the influence of the elastic force of the spring 11, and the rotating rod 13 will fall to achieve the effect of automatically resetting the limit block 15. The overall operation is relatively convenient.

[0040] By providing the disassembly assembly 2, the purpose of facilitating the disassembly and maintenance of a single water supply pipe body 3 can be achieved, thereby solving the problem that it is difficult to separate the connected pipes when the pipes are currently connected by welding.
