Abstract
The utility model discloses a bayonet-socket pipe joint, the connection of the bayonet on an outer pipe joint and the clamping joint on an inner pipe joint, and the principle of quick connection and releasing are the same as that of bayonet-socket bulbs. The utility model has the advantages of simple structure, simple and reliable operation, and good self-sealing property. Particularly, the utility model and a hose can be made into a hose assembly of a quick pipe joint, and the utility model can be used in hydraulic engineering and other industries related to liquid.
Description
A kind of bayonet-type coupling is used for pipeline and connects.
At present, the most close with the utility model pipe joint is a swollen shaft type pipe joint (seeing QZB275-77).This joint adopts the steel ball locking medium, is to utilize overcoat that 6～12 steel balls on the socket body are pressed in " V " type groove that drops on the spigot body and realize quick combination.This method is used simply, makes things convenient for, should be operated.But because this swollen shaft type pipe joint structure complexity, component are many, and volume is big, complex process so brought, the deficiency that cost is higher.
The purpose of this utility model be for provide a kind of simple in structure, volume is less, production and processing is convenient, the quick coupling that cost is low.
The utility model adopts the bayonet fittings method, that is: the card wedge along the equally distributed protrusion of circumference is arranged on the spigot external diameter, on the caliber of corresponding with it fittings body outside bayonet socket is arranged, and bayonet socket with block wedge and make the shape that is complementary.The bayonet socket number is decided on the fittings body diameter, but answers 〉=2.
The utility model adopts the bayonet fittings method, and will block wedge and bayonet socket is made the shape that is complementary, and blocks can be stabilized in this position after wedge enters bayonet socket, plays the effect that is fastenedly connected.This kind method connecting pipeline does not need more fastening piece, and is simple in structure, easily uses, and cost of production is low.
Be described further below in conjunction with accompanying drawing
Accompanying drawing 1 is the bayonet-type coupling structural drawing
Accompanying drawing 2 is the card wedge and the bayonet socket of bayonet-type coupling
1-spigot body 2-elastic support 3-spring
4-seal ring 5-seal ring 6-one-way valve
7-socket body 8-seal groove 9-bayonet socket 10-card wedge
In force, the card wedge ［ 10 ］ of bayonet-type coupling evenly distributes at the external diameter upper edge of spigot body ［ 1 ］ circumference, and quantity is decided on the fittings body diameter, but answers 〉=2.The afterbody of fittings body joins by the pipe joint of threaded coupling and flexible pipe or other form.Elastic support ［ 2 ］ is the three-pawl type stamping part, is used for the maximum displacement of supported spring ［ 3 ］ and restriction one-way valve ［ 6 ］.The spool of one-way valve ［ 6 ］ is installed in the mesopore of support, and the other end is a taper, is provided with seal groove ［ 8 ］ on the conical surface, places " D " formation " O " shape seal ring ［ 5 ］ in the groove.Before outer tube joint was connected, the spool of one-way valve ［ 6 ］ was pressed in seal ring ［ 5 ］ on the conical surface of fittings body, thereby pipe joint is not leaked under the effect of spring ［ 3 ］.
Outside on the caliber of fittings body ［ 7 ］, have with spigot body ［ 1 ］ on the number and the corresponding bayonet socket ［ 9 ］ that distributes of card wedge ［ 10 ］, and the card wedge ［ 10 ］ boss and bayonet socket ［ 9 ］ for surface of contact be complementary trapezoidal, also can be triangle, garden arc or " ［ " shape.Seal arrangement ［ 4 ］ is arranged on the socket body ［ 7 ］, and this device guarantees not have seepage when two joints are connected or throw off.
Claims (4)
1, a kind of bayonet-type coupling, by two fittings bodies, spring bracket, spring, seal ring, automatic one-way valve are formed, and it is characterized in that being evenly distributed with the card wedge at spigot body diameter upper edge circumference, on the corresponding caliber of fittings body outside bayonet socket are arranged.
2,, it is characterized in that the surface of contact of boss of bayonet socket inside groove and card wedge on the socket body caliber is the shape that is complementary according to the described bayonet-type coupling of claim 1.
3,, it is characterized in that the quantity of card wedge and bayonet socket answers 〉=2 according to the described bayonet-type coupling of claim 1.
4,, it is characterized in that on the taper one-way valve of two fittings body inner chambers, a seal groove being arranged respectively according to the described bayonet-type coupling of claim 1.
