Description

Technical Field

[0001] The utility model relates to the technical field of PVC lift pipes, in particular to a PVC lift pipe with a quick splicing structure. Background Art

[0002] The lift refers to the height to which the water pump can lift water (that is, the water in the home needs to be lifted from a few meters underground to the main drainage pipe). It is an important working performance parameter of the pump. In the process of water pump lift, pipes are generally required to guide the water. Compared with cement pipes, the lift of the water pump using hoses, PE pipes, and PVC pipes has less pipeline loss.

[0003] In the prior art, when installing the PVC lift pipe, the PVC lift pipe is generally connected to the water pump. When the length of the PVC lift pipe is not enough, the pipe needs to be spliced. At present, hot-melt welding is used when splicing the PVC lift pipe. Although this splicing method has the advantage of firm installation, it takes manpower to perform hot-melt treatment and then splice it, which is time-consuming. In addition, when the PVC lift pipe is subsequently disassembled, it is not very convenient due to hot-melt welding, and a lot of time is needed for disassembly, which increases the workload of the staff.

[0004] To this end, we propose a PVC lift pipe with a quick splicing structure. Summary of the invention

[0005] The utility model aims to provide a PVC lift pipe with a quick splicing structure 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 PVC lift pipe with a quick-joining structure, comprising a pipe body, the pipe body having two, the outer surfaces of the two pipe bodies are both provided with mounting sleeves, a sealing mounting assembly, the sealing mounting assembly is mounted inside the mounting sleeve, the sealing mounting assembly is used to seal the pipe body as a whole, the sealing mounting assembly can effectively prevent water leakage during the use of the device, and a fixing assembly, the fixing assembly is mounted on the outer surface of the mounting sleeve on the left side, the fixing assembly is used to quickly splice the two pipe bodies.

[0007] Preferably, the sealing installation assembly includes an installation sleeve, the inner walls of the two installation sleeves are provided with internal threads, the two installation sleeves are threadedly connected to the corresponding pipe body through the internal threads, the right side of the installation sleeve on the left is fixedly connected with an annular block, the left side of the installation sleeve on the left is fixedly connected with a fixing ring, the left side of the fixing ring is fixedly connected with multiple circles of sealing rings, and the left side of the annular block and the right side of the fixing ring are fixedly installed with sealing strips.

[0008] Preferably, the positions and sizes of the two sealing strips correspond to the right side surfaces and the left side surfaces of the two pipe bodies respectively.

[0009] Preferably, a water diversion pipe is fixedly connected to the left side surface of the fixing ring, and the water diversion pipe extends to the interior of the left side pipeline body.

[0010] Preferably, the fixing assembly comprises a mounting bracket, and the mounting brackets are four, and the four mounting brackets are all mounted on the outer surface of the mounting sleeve on the left side, and a slot is opened inside each of the mounting brackets, and a lifting rod is clamped inside each of the slots, and a threaded rod is rotatably connected to the upper surface of the mounting bracket, and the threaded rod extends to the inside of the lifting rod and is threadedly connected to the lifting rod, and the other end of each lifting rod is fixedly connected to a sealing plate, and each sealing plate is fixedly connected to a fixing thorn at one end close to the pipe body.

[0011] Preferably, four guide grooves are provided on the right side surface of the annular block, and four guide blocks matching the size of the water diversion pipe are fixedly connected to the outer surface of the water diversion pipe.

[0012] Preferably, the left sides of the four guide blocks are fixedly connected to rubber blocks, the size of each rubber block is matched with the size of the water diversion pipe, and the outer surface of the pipe body on the left side is provided with four circular holes corresponding to the positions of the fixed thorns, and the position of each circular hole is matched with the position of the corresponding rubber block.

[0013] Preferably, the top end of each threaded rod is fixedly connected with a hexagonal block.

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

[0015] 1. When it is necessary to splice the PVC lift pipe, first insert the installation sleeve on the left side into the interior of the pipe body on the left side. By setting a threaded connection between the installation sleeve and the pipe body, the installation sleeve on the left side and the pipe body can be connected by rotating the installation sleeve. The same is true for the installation sleeve and the pipe body on the right side. Then, insert the water diversion pipe into the interior of the pipe body on the left side through the annular block. By setting a guide block and a guide groove for clamping, the water diversion pipe can be inserted into the interior of the pipe body on the left side to play a guiding role. When the device starts working, the interface between the annular block and the fixing ring can be sealed by the sealing ring, and the interface between the annular block and the pipe body on the left and the fixing ring and the pipe body on the right can be sealed by the sealing strip.

[0016] A sealing installation component is provided. When the staff splices the PVC growing pipe, they can perform sealing treatment to reduce water leakage during use of the device. The guide block and the guide groove can serve as a guide when installing the spliced ​​pipe and sleeve, so as to complete the installation and sealing work more quickly.

[0017] 2. When the water diversion pipe is inserted into the left side of the pipe body, the staff uses a wrench or other tools to rotate multiple hexagonal blocks in the positive direction in sequence, so that the threaded rod can be rotated synchronously, and the lifting rod threadedly connected to the threaded rod can be lowered. At this time, the sealing plate and the fixed thorns will be lowered synchronously. At this time, the fixed thorns will penetrate through the round holes and extend into the interior of the pipe body, and then the fixed thorns will pierce into the corresponding rubber blocks, so as to firmly fix the position of the water diversion pipe. Moreover, when the sealing plate is lowered, the round holes will be closed to prevent water leakage in the round holes. When the pipe body needs to be disassembled, it is only necessary to rotate multiple hexagonal blocks in the opposite direction. Similarly, the fixed thorns can release the lock on the water diversion pipe, and the two pipe bodies can be easily disassembled.

[0018] By setting the fixing components, the overall operation can be simpler and faster when splicing two pipe bodies, and it is also more convenient to disassemble the pipe bodies. BRIEF DESCRIPTION OF THE DRAWINGS
