Description

The portable type pipe joint

The utility model relates to pipe joint, specifically a kind of portable type pipe joint that is suitable for the metal tube connection.

Existing pipe joint generally adopts flange-type or thread type.Cumbersome when flange fitting is installed, need many bolts of flange periphery are tightened, it is big to take activity space; Though it is little that thread type takies activity space, it will be in the tapping of the end of connected tube, and it is same inconvenient to operate.

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple to operately, connects rapidly, takies the little portable type pipe joint of activity space.

At the foregoing invention purpose, the utility model adopts following technological scheme: a kind of portable type pipe joint, comprise a pipe joint body, this pipe joint body in a tubular form, its two outer wall or inwall can match with the inwall or the outer wall of connected tube respectively, its special way is that every outer wall of described pipe joint body or inner wall surface edge circumferentially have annular recess, anti-crowded mill elastic washer is housed in groove, this packing ring and this contact level of pipe joint are evenly equipped with several drops grooves along Zhou Fangxiang, have hemispherical dimples with the corresponding pipe joint body surface of drops groove, steel ball is embedded between hemispherical dimples and the drops groove, circumferentially evenly be furnished with several drops grooves on the bead outer surface edge, the direction of this drops groove is opposite with the direction of washer inner surface drops groove, anti-crowded mill elastic ball is housed in this groove, annular seal ring is housed at the inboard pipe joint body surface on one side of annular recess.

When the utility model is installed, outer surface or the internal surface that two velamen connecting tubes connect the end is inserted at two of pipe joint respectively, presses certain orientation swivel joint body, two velamen connecting tubes can be coupled together; During dismounting, need only can gently the utility model and connected tube be separated with the pipe joint body by opposite direction rotation suitablely.The utility model is simple in structure, and is easy to use, and installing/dismounting is easy, rapid, do not need to take bigger space, and good airproof performance, be suitable for provisional connection between the metallic conduit.

Below in conjunction with the accompanying drawing illustrated embodiment, describe the utility model in detail.

Fig. 1 is embodiment 1 a structural representation.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the E-E sectional view of Fig. 1.

Fig. 4 is the I place partial enlarged drawing of Fig. 1.

Fig. 5 is the C-C view of Fig. 2.

Fig. 6 is the d-d view of Fig. 2.

Fig. 7 is embodiment's 2 structural representations.

The utility model mainly is made up of in a tubular form pipe joint body 1 and packing ring 2.

Embodiment 1: referring to figs. 1 through Fig. 6, the outer wall at pipe joint 1 two of this embodiment is corresponding with connected tube 6 mouth of pipe inner wall shape, can insert wherein, each outer wall surface is along circumferentially having a loop groove 8, also can open multi-turn annular recess 8, packing ring 2 is housed in groove 8, this packing ring 2 adopts anti-crowded mill elastic material (as rubber) to make, this packing ring 2 along the circumferential direction is evenly equipped with 4 drops grooves 7 with pipe joint body 1 surface of contact, the internal surface of drops groove 7 is made pitted skin, to increase friction factor.Have the hemisphere type pit with above-mentioned drops groove 7 corresponding pipe joint bodies 1 surface, steel ball 3 is embedded between hemispherical dimples and the drops groove 7.Circumferentially evenly be furnished with 4 drops grooves 9 that equate with groove 7 quantity on above-mentioned packing ring 2 outer surfaces edge, the internal surface of this groove 9 also is pitted skin, to increase friction factor, the direction of groove 9 is opposite with the direction of groove 7, anti-crowded mill elastic ball 4 is housed in groove 9, and this ball 4 can adopt rubber to make.On annular recess 8 inboard pipe joint bodies on one side 1 surface annular seal ring 5 is housed.

Embodiment 2: with reference to Fig. 7, the inwall at pipe joint 1 two of this embodiment is corresponding with connected tube 6 mouth of pipe outer wall shapes, but in the connected tube mouth of pipe insertion tube joint, each inner wall surface at pipe joint 1 two is along circumferentially having a circle or a multi-turn annular recess 8, packing ring 2 with embodiment's 1 same material is housed in groove 8, this packing ring 2 and pipe joint body 1 surface of contact are evenly equipped with 4 drops grooves 7 identical with embodiment 1, have the hemisphere type pit with above-mentioned drops groove 7 corresponding pipe joint bodies 1 surface, steel ball 3 is embedded between hemispherical dimples and the drops groove 7.Be evenly equipped with 4 drops grooves 9 identical at above-mentioned packing ring 2 outer surfaces, the ball 4 identical with embodiment 1 is housed in the groove 9 with embodiment 1.In annular recess 8 inboard pipe joint body internal surface on one side annular seal ring 5 is housed.

Working principle of the present utility model is with reference to Fig. 2, when pipe joint body 1 is rotated counterclockwise, drive rubber washer 2, do not have the extruding phenomenon between pipe joint body 1 and connected tube 6 tube walls, be in pine and unload state, when pipe joint body 1 turns clockwise, pipe joint body 1 is owing to produce extruding between steel ball 3 effects and the rubber washer 2, connected tube 6 is because ball 4 effects produce extruding simultaneously, and this moment, connected tube 6 was in tightening state with pipe joint.

The structure at two, the utility model pipe joint left and right sides can be symmetrical.The drops groove quantity of described anti-crowded mill elastic washer outer surface can be identical with internal surface drops groove quantity, and be positioned at the top of internal surface drops groove.This pipe joint is applicable to the interim connection of all kinds of metal tubes.
