Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PVC pipe processing, and specifically relates to an interface capable of quickly splicing PVC pipes. Background Art
[0002] PVC is the abbreviation of Polyvinylchlorid, which is mainly composed of polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive.
[0003] PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) Rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin and stabilizer, lubricant, etc., is extruded by hot pressing. It is the earliest plastic pipe material developed and applied.
[0004] PVC-U pipes have strong corrosion resistance, are easy to bond, are cheap, and have a hard texture. However, due to the leakage of PVC-U monomers and additives, they are only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling liquids, food, ultrapure liquids, slurries, gases, compressed air, and vacuum system applications.
[0005] PVC-O pipe, whose Chinese name is biaxially oriented polyvinyl chloride, is the latest evolution of PVC pipe. It is manufactured through a special orientation processing technology. The PVC-U pipe produced by extrusion is stretched axially and radially to make the PVC long-chain molecules in the pipe arranged regularly in the biaxial direction, thus obtaining a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.
[0006] PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings and the surface of leather, but because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), the physical properties are poor (for example, water pipes need to withstand a certain water pressure, so soft PVC is not suitable for use), so its scope of use is limited. Hard PVC does not contain plasticizers, so it is easy to shape and has good physical properties, so it has great development and application value. In the production process of polyvinyl chloride materials, several additives must be added, such as stabilizers, plasticizers, etc. If all environmentally friendly additives are used, then PVC pipes are also non-toxic, odorless and environmentally friendly products.
[0007] Production process: raw material + additive preparation → mixing → conveying and feeding → forced feeding → conical twin-screw extruder → extrusion die → sizing sleeve → spray vacuum shaping box → immersion cooling water tank → ink printer → crawler tractor → knife lifting and cutting machine → pipe stacking rack → finished product inspection and packaging.
[0008] PVC pipes have been well received by the engineering community for their light weight, corrosion resistance, high compressive strength, safety and convenience. Driven by the rapid economic development, the development of PVC pipes in my country is very rapid.
[0009] During the use of PVC pipes, different PVC pipes need to be spliced together according to different length requirements, and only after splicing can the length of use be met. However, the commonly used PVC pipe splicing is relatively cumbersome. In view of this, an interface is developed to quickly splice PVC pipes. Utility Model Content

The limit frame 3-1 is connected to a fixing frame 3-2 by a pin shaft, and the limit frame 3-1 is connected to a fixing bolt 3-3 by a pin shaft. The fixing bolt 3-3 is engaged with a fixing nut 3-4, and the limit frame 3-1 is provided with a reinforcement frame 3-5. The reinforcement frame 3-5 is provided with a threaded opening 3-6, and a threaded rod 3-7 is engaged in the threaded opening 3-6. A universal joint 3-8 is fixedly installed on the threaded rod 3-7.
[0037] In this embodiment, after the sealing gasket 2 on the limit frame 3-1 is placed on the pipe body 1, the sealing gasket 2 on the pipe body 1 is fitted against the pipe body 1, and after the fixing nut 3-4 is screwed, the fixing nut 3-4 rotates on the fixing bolt 3-3, so that the pipe body 1 is clamped when spliced, thereby realizing the assembly of the pipe body 1.
[0038] Specifically, the reinforcement component 4 includes a fixed plate 4-1, a connecting rod 4-2 is provided on the fixed plate 4-1, a slider 4-3 is provided on the connecting rod 4-2, a slide groove 4-4 is opened on the reinforcement frame 3-5, the fixed plate 4-1 is a semicircular structure, and the fixed plate 4-1 fits with the pipe body 1.
