Abstract
The utility model discloses a plastic pipe connector. A plastic cannula is embedded in the end of a plastic pipeline to cause the plastic pipe connector to expand. Frictional force generated by pressurizing a coniform sealing ring by a screw cap is made use of or a clamp ring pressing the plastic pipe is made use of to lock the plastic pipe. The plastic pipe connector has the advantages of simple structure, low cost, and easy loading and unloading. The plastic pipe connector is suitable for water, gas, oil discharging and feeding systems and plastic pipes for various chemical liquid flow channels.
Description
The utility model relates to pipeline connection technology, is a kind of widely used plastic pipe link.It belongs to life and industrial category.
Present plastic pipe connects the glue that adopt more and connects agent, easily leaks, and makes troubles to maintenance.Or with metal nut locking, easily get rusty, complex structure, price is expensive.
It is raw material with plastics that the purpose of this utility model is to develop a kind of, simple in structure, cheap, can load and unload by hand, use for a long time no-leak, and rustless plastic pipe link.
Realize that the utility model purpose technological scheme is such: embed the plastic pipe end with plastic bushing, it is swollen.The friction that taper seal washer pressurization is produced by nut, or utilize the snap ring plastic pipe that is locked to add the nut pressurization again, thus the locking plastic pipe.
The utility model concrete structure is provided by following enforcement and accompanying drawing:
Accompanying drawing is a sectional drawing of the present utility model.Wherein accompanying drawing 1: sleeve pipe (1), seal washer (2), nut (3).Accompanying drawing 2: connecting body (4), screwed pipe (5), screwed pipe (6), cover mouth (7), collar (8), nut (9).
Concrete structure of the present utility model and working condition now are described in detail in detail in conjunction with the accompanying drawings.
Nut in the accompanying drawing 1 (3) is an internal thread.The internal diameter of sleeve pipe (1) is slightly larger than the external diameter of connected plastic pipe.The plastic pipe end is temperature a little, can embed sleeve pipe (1), and the plastic pipe end is swollen.Seal washer (2) and nut (3) are inserted in plastic pipe.The outer surface of seal washer is a cone, and the size of its internal diameter equates with the external diameter of plastic pipe.Sleeve pipe (1) is lower than the end face of nut (3) with the equal in length of seal washer (2).Between seal washer (2) and nut (3), keep certain space, as the joint location of inserting another external screw thread pipeline.When another pipeline and nut (3) when being meshed, by nut (3) the friction locking plastic pipe that pressurization produces to taper seal washer (2).
Connecting body in the accompanying drawing 2 (4) is three stair-stepping hollow pipes, and screwed pipe (5) is external screw thread with screwed pipe (6), and cover mouth (7) has the collar (8) of a projection, and their internal diameter and external diameter successively decrease successively, and nut (8) is meshed with screwed pipe (6).Plastic pipe connects cover mouth (7), and when nut (9) meshed with screwed pipe (6), nut (9) was pushed down the collar on the cover mouth (7), the locking plastic pipe.The pipeline of another internal screw thread is meshed with screwed pipe (5), locking pipe, and such two pipelines just link together tightly, can not leak.Use sleeve pipe (1), seal washer (2), nut (3), connecting body (4) and nut (9), also can firmly pin the plastic pipe of two no threads.
The utility model is compared with existing catherer connection tube, and following advantage is arranged:
1. the soft or hard of the pipe matter of connected pipe, the big I of bore are selected arbitrarily according to different needs;
2. connecting tube can be plastics, also one be plastics, another root is non-plastics.
3. non-corrosive does not corrode, and does not leak;
4. installation and removal fast simplely;
5. applicable to the plastic pipe of plumbing, exhaust, oil system and the circulation of various chemical liquid;
6. applicable to the plastic duct system of low pressure and high pressure;
7. make simple and easy, cheap.
Claims (1)
1. plastic pipe link, it comprises sleeve pipe (1), seal washer (2), nut (3), seal washer (4), nut (5), it is characterized in that nut (3) is an internal screw thread, the internal diameter of sleeve pipe (1) is slightly larger than the external diameter of connected plastic pipe, sleeve pipe (1) is embedded plastic pipe also to swell the plastic pipe end, seal washer (2) and nut (3) are inserted in plastic pipe, the outer surface of seal washer is a cone, the size of its internal diameter equates with the external diameter of plastic pipe, sleeve pipe (1) is lower than the end face of nut (3) with the equal in length of seal washer (2), between seal washer (2) and nut (3), keep certain space, as the joint location of inserting another external screw thread pipeline.
