Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipes, in particular to a high-impact PVC-UH water supply pipe. Background Art

[0002] Water supply pipes are divided into metal pipes, plastic pipes, and composite pipes. Metal pipes include copper pipes, stainless steel pipes, steel pipes, and plastic pipes. Water supply pipes generally refer to pipes used in domestic hot and cold water systems, including central air-conditioning systems, floor heating systems, and domestic drinking water systems. During use, water supply pipes need to withstand greater impact forces, and high-impact PVC-UH water supply pipes are required.

[0003] In the prior art, there are the following problems:

[0004] Usually, PVC-UH water supply pipes are made of high-impact resistant water supply pipes by heating and melting rigid polyvinyl chloride resin and then extruding the heated and melted rigid polyvinyl chloride resin. When connecting existing PVC-UH water supply pipes, most of them are coated with glue on both ends of the PVC-UH water supply pipes and then connected and bonded. The glue is prone to aging after long-term use, thereby affecting the sealing effect of the joint of the PVC-UH water supply pipes. At the same time, the impact resistance of existing PVC-UH water supply pipes is relatively general, making the PVC-UH water supply pipes prone to rupture and damage when subjected to a large impact force. Utility Model Content

[0005] The purpose of the utility model is to provide a high-impact PVC-UH water supply pipe to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-impact PVC-UH water supply pipe, comprising a water supply pipe body and a docking sleeve sleeved on one end of the water supply pipe body, the water supply pipe body being provided with a sealing assembly and an anti-impact assembly, the sealing assembly comprising a fixing ring fixedly mounted on the inner side of the docking sleeve, the fixing ring being located on one side of the water supply pipe body, the inner wall of the docking sleeve being fixedly connected with a first sealing ring, the first sealing ring being located on one side of the fixing ring, the inner wall of the docking sleeve being fixedly connected with a second sealing ring, the second sealing ring being located on the other side of the fixing ring, the anti-impact assembly comprising a wrapping belt wrapped around the outer periphery of the water supply pipe body, the wrapping belt being fixedly connected to the outer wall of the water supply pipe body, the inside of the wrapping belt being fixedly connected with a plurality of fixing wires.

[0007] When docking two water supply pipe bodies, by inserting one end of one water supply pipe body into one side of the docking sleeve, and by inserting the other end of the other water supply pipe body into the other side of the docking sleeve, the first sealing ring and the second sealing ring can be used to conveniently seal the docking point of the water supply pipe body, thereby improving the sealing effect. By wrapping the wrapping tape around and fixing it on the periphery of the water supply pipe body, the fixed wire can reinforce the water supply pipe body, thereby avoiding the situation where the water supply pipe body is cracked due to excessive impact force inside the water supply pipe body, thereby improving the impact resistance of the water supply pipe body.

[0008] Preferably, the water supply pipe body is provided with guide slopes at both ends, and the inner side of the docking sleeve is provided with two guide grooves, which are respectively located at both ends of the docking sleeve. The guide slopes and the guide grooves guide each other, so that the water supply pipe body can be easily inserted into the docking sleeve.

[0009] Preferably, the two first sealing rings are fixedly connected to the butt joint sleeve via a first fixing groove. Two first sealing grooves are defined on the periphery of the water supply pipe body, the two first sealing grooves being located on one side of the wrapping tape and corresponding to the first sealing rings. The first fixing grooves can secure the first sealing rings, and by positioning the first sealing rings within the first sealing grooves, a seal can be achieved between one end of the water supply pipe body and the butt joint sleeve.

[0010] Preferably, the fixing ring is provided with limiting grooves on both sides, the inner sides of each limiting groove are fixedly connected to a sealing ring, and the outer sides of the sealing ring extend from the limiting groove. The limiting grooves can be used to limit and fix the sealing ring, and when the water supply pipe body is docked, the two ends of the water supply pipe body squeeze the sealing ring, thereby conveniently sealing the two ends of the water supply pipe body.

[0011] Preferably, an anti-skid pad is fixedly installed on the periphery of the docking sleeve, and the plurality of fixing wires are fixedly connected by fixing rods. The anti-skid pad can make the periphery of the docking sleeve have a good anti-skid effect, making it convenient to take and fix the docking sleeve, and the fixing rod can fix the plurality of fixing wires.

[0012] Preferably, the second sealing ring is fixedly mounted to the butt joint sleeve via a second fixing groove. Two second sealing grooves are defined on the periphery of the water supply pipe body, the two second sealing grooves being located on the other side of the wrapping tape, and the two second sealing grooves corresponding to the two second sealing rings. The second fixing grooves secure the second sealing ring, and by positioning the second sealing ring within the second sealing grooves, a seal is achieved between the other end of the water supply pipe body and the butt joint sleeve.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By providing a wrapping tape, a fixing wire, a docking sleeve, a first sealing ring and a second sealing ring that cooperate with each other, when docking two water supply pipe bodies, by inserting one end of one water supply pipe body into one side of the docking sleeve, the first sealing ring is located in the first sealing groove, and by inserting the other end of the other water supply pipe body into the other side of the docking sleeve, the second sealing ring is located in the second sealing groove. After docking, the two ends of the water supply pipe body inserted into the docking sleeve are squeezed to squeeze the sealing rings, which can facilitate the sealing of the docking point of the water supply pipe body and improve the sealing effect. The water supply pipe body can be wrapped and fixed by the wrapping tape and the fixing wire to avoid the situation where the water supply pipe body is cracked due to excessive impact force inside the water supply pipe body, thereby improving the impact resistance of the water supply pipe body.
