Abstract
The invention relates to a high-pressure attachment joint of a PVC (polyvinyl chloride) air pipe. The high-pressure attachment joint comprises a joint body inside which a through hole is formed; a PVC air pipe connector is arranged at one end opening of the through hole and comprises a connecting part and an end part, wherein the end part is configured to be conical; a circle of locking rib ring is formed between the end part and the connecting part; a connecting screw thread is also arranged on one side, corresponding to the PVC air pipe connector, of the outer edge of the joint body; a locknut is screwed on the connecting screw thread; a circle of step structure is arranged on the inner wall of the locknut; the step structure is matched with the locking rib in order to lock the PVC air pipe; a columnar pipe body is arranged at the other end of the through hole of the joint body; the columnar pipe body and a rapid attachment joint are matched with each other in an inserted manner. The high-pressure attachment joint disclosed by the invention has the characteristics of being convenient to install, reliable in connection and durable in use.
Description
Technical field
The present invention relates to a kind of high pressure connector lug of tracheae, specifically a kind of high pressure connector lug of PVC tracheae.
Background technique
Current high-pressure air pipe generally adopts direct insertion fast connector, tracheae then adopts the tracheae of PU material, P U tracheae direct grafting fast connector can realize quick connection, it is quite convenient to connect, but the impact of PU tracheae climate is larger, summer due to temperature higher, PU tracheae entirety is softening makes the intensity of body reduce, pressurized gas in pipe by time body can expand and even break, simultaneously winter due to temperature lower, the sclerosis of PU tracheae entirety, body is hardening to become fragile, and time bending, PU tracheae easily ruptures, there is a kind of PVC tracheae in addition, it is a kind of combined type tracheae, skin is PVC coating, internal layer is rubber and plastic body, the strengthening net of one deck industry strong silk braiding is set between internal and external layer, the soft intensity of this tracheae quality is high substantially not by the impact of temperature, there is PU tracheae not there is stability and intensity, but this PVC tracheae is owing to adopting multi-layer structure, cannot directly coordinate with fast connector grafting, because straight cutting coordinates pressurized gas to be easy to enter in the interlayer between the internal and external layer of composite pipe, cause PVC tracheae overall damaged, this is also that PVC tracheae does not coordinate reason with fast connector always.
Summary of the invention
The object of the present invention is to provide a kind of high pressure connector lug of PVC tracheae, one end of this jointing is connected with PVC tracheae, the other end directly coordinates with fast connector grafting, make PVC tracheae also can with fast connecting joint with the use of, have easy for installation, connect reliable, long-lived feature.
A kind of high pressure connector lug of PVC tracheae, it is characterized in that: comprise the joint body that inside is provided with through hole, the wherein Single port of through hole is provided with PVC air pipe connector, PVC air pipe connector comprises joint and end, the tapered setting in end, a circle card muscle is formed between end and joint, also connecting thread is provided with in the side of the corresponding PVC air pipe connector of the outer rim of joint body, a locking nut is had to be screwed on this connecting thread, locking nut inwall is provided with a circle ledge structure, and ledge structure and card muscle lock PVC tracheae; Arrange column body at the other end of joint body through hole, column jecket body coordinates with fast connecting joint grafting.
Described joint body, PVC tracheae jointing and column body are structure as a whole, and are made up of metal or hard plastics.
The present invention is by being connected on the PVC air pipe connector of high pressure connector lug by PVC air pipe sleeve, and coordinate with the card muscle of PVC air pipe connector by the step of locking nut inwall PVC tracheae is locked, play good fixing and sealing effect, the other end column body of joint body, column body is generally made up of metal or hard plastics, column body coordinates with fast connecting joint grafting, achieve coordinating of PVC tracheae and fast connecting joint, adopt PVC tracheal replacement PU tracheae, overcome existing PU tracheae to affect by natural environment and climate, poor stability, the defects such as working life is short.

Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposition texture schematic diagram of the present invention;
Fig. 3 is internal structure schematic diagram of the present invention.
Embodiment
As Figure 1-3, a kind of high pressure connector lug of PVC tracheae, it is characterized in that: comprise the joint body 1 that inside is provided with through hole, the wherein Single port of through hole is provided with PVC air pipe connector 2, PVC air pipe connector 2 comprises joint 21 and end 22, the tapered setting in end 22, form one between end 22 and joint 21 and enclose card muscle 23, connecting thread 11 is also provided with in the side of the corresponding PVC air pipe connector 2 of the outer rim of joint body 1, a locking nut 3 is had to be screwed on this connecting thread 11, locking nut 3 inwall is provided with a circle ledge structure 31, ledge structure 31 and card muscle 23 lock PVC tracheae, arrange column body 5 at the other end of joint body 1 through hole, column jecket body 5 coordinates with fast connecting joint grafting, the joint body 1 stated, PVC tracheae jointing 2 and column body 5 are structure as a whole, and are made up of metal or hard plastics.
First PVC tracheae is passed locking nut 3 when the present invention uses, then PVC air pipe sleeve is connected on PVC air pipe connector 2, then locking nut 3 spins with the connecting thread 11 of joint body 1, now ledge structure 31 coordinates with card muscle 23 PVC tracheae is tightly fixed on PVC air pipe connector 2, and ensure reliability and the sealing of connection, then column body 5 is plugged into the connection namely fast connecting joint completing PVC tracheae and fast connecting joint; Instant invention overcomes the problem that PVC tracheae cannot coordinate with fast connecting joint, solve the defect that the easy climate of existing PU tracheae affects unstable properties, have easy for installation, connect reliable, long-lived feature.
Claims (2)
1. the high pressure connector lug of a PVC tracheae, it is characterized in that: comprise the joint body that inside is provided with through hole, the wherein Single port of through hole is provided with PVC air pipe connector, PVC air pipe connector comprises joint and end, the tapered setting in end, a circle card muscle is formed between end and joint, also connecting thread is provided with in the side of the corresponding PVC air pipe connector of the outer rim of joint body, a locking nut is had to be screwed on this connecting thread, locking nut inwall is provided with a circle ledge structure, and ledge structure and card muscle lock PVC tracheae; Arrange column body at the other end of joint body through hole, column jecket body coordinates with fast connecting joint grafting.
