The utility model relates to a kind of pipe joint.

Background technique

At Petrochemical Pipe Joints, the connecting tube of upper and lower end needs to use a connecting head, in traditional approach, be adopt being connected between screw thread thread mostly, outside winds up with gummed paper again, therefore loaded down with trivial details when mounted, and more loaded down with trivial details during detachable maintaining, although and thread fiting mode is simple, thread easily weares and teares, working life is not long, easily leaks.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of long service life, installs and removes, overhauls conveniently, the better pipe joint of anti-leakage.

The utility model is achieved through the following technical solutions: a kind of pipe joint, comprise the connecting tube of upper and lower end and the connecting head for being connected upper and lower end connecting tube, the upper and lower opening end of described connecting tube is provided with a step, the upper and lower opening end inwall being positioned at connecting tube offers more than one draw-in groove, the inwall both sides of described draw-in groove are respectively provided with a slot, the middle draw-in groove inwall being positioned at two slots offers a groove, described groove communicates with connecting tube outside, the outer side wall of described connecting head is provided with the projection identical with pocket numbers on connecting tube, be positioned at projection both sides and be provided with the fixture block fastened with draw-in groove inwall slot, the upper-end surface of described projection offers a cavity, described cavity is provided with a fixed block, described fixed block lower end is positioned at cavity and is provided with a spring.

As preferably, described connecting tube is positioned at groove outside and is provided with a circle chute, described chute is movably installed with a collar, and described groove is positioned at connecting tube outer upper ends and is equipped with a teeth groove, the lower of described teeth groove is rectified groove, and the width of teeth groove equals the width of groove.

As preferably, the inner side surface of the described collar is provided with the gear shaping identical with groove quantity, and described gear shaping is all positioned at teeth groove, and the inner side surface of described gear shaping is an arc shaped surface.

As preferably, the end face outside of described fixed block is equal together with the outside end face of groove, and the upper end outer side surface of described fixed block is an arc shaped surface.

The beneficial effects of the utility model are: the utility model, when connecting tube and connecting head are assembled, connects without the need to using screw thread thread, long service life, and conveniently, anti-leakage is better for mounting or dismounting, maintenance.

Accompanying drawing explanation

Fig. 1 is the structural representation of connecting tube in the utility model;

Fig. 2 is the structural representation of connecting head in the utility model;

Fig. 3 is overall structure schematic diagram of the present utility model;

Fig. 4 is the structural representation of gear shaping.

Coding in figure is respectively: 1 is connecting tube, and 2 is step, and 3 is slot, and 4 is draw-in groove, and 5 is connecting head, and 6 is fixture block, and 7 is spring, and 8 is projection, and 9 is fixed block, and 10 is the collar, and 11 is chute, and 12 is groove, and 13 is teeth groove, and 14 is gear shaping.

Embodiment

As depicted in figs. 1 and 2, this pipe joint, comprise the connecting tube 1 of upper and lower end and the connecting head 5 for being connected upper and lower end connecting tube 1, the upper and lower opening end of described connecting tube 1 is provided with a step 2, the upper and lower opening end inwall being positioned at connecting tube 1 offers more than one draw-in groove 4, the inwall both sides of described draw-in groove 4 are respectively provided with a slot 3, the middle draw-in groove inwall being positioned at two slots 3 offers a groove 12, described groove 12 communicates with connecting tube 1 outside, the outer side wall of described connecting head 1 is provided with the projection 8 identical with draw-in groove 4 quantity on connecting tube 1, be positioned at projection 8 both sides and be provided with the fixture block 6 fastened with draw-in groove 4 inwall slot 3, the upper-end surface of described projection 8 offers a cavity, described cavity is provided with a fixed block 9, described fixed block 9 lower end is positioned at cavity and is provided with a spring 7.

As shown in Figure 3, connecting tube 1 is positioned at groove 12 outside and is provided with a circle chute 11, described chute 11 is movably installed with a collar 10, described groove 12 is positioned at connecting tube 1 outer upper ends and is equipped with a teeth groove 13, the lower of described teeth groove 13 is rectified groove 12, and the width of teeth groove 13 equals the width of groove 12.

As shown in Figure 3 and Figure 4, the inner side surface of the collar 10 is provided with the gear shaping 14 identical with groove 12 quantity, and described gear shaping 14 is all positioned at teeth groove 13, and the inner side surface of described gear shaping 14 is an arc shaped surface.

Wherein, the end face outside of fixed block 9 is equal together with the outside end face of groove 12, and the upper end outer side surface of described fixed block 9 is an arc shaped surface.

In use, first fitted by the step surface of the upper and lower end face of connecting head and upper and lower end connecting tube, the width of step surface is greater than the width of connecting head, there will not be the situation of seepage when water drops from top to bottom; Utilize the projection both sides fixture block outside connecting head to be stuck in the slot of draw-in groove both sides of connecting tube, then the fixed block of projection head snaps in groove, realizes being fastenedly connected;

During dismounting, only need the collar slide downward of connecting tube outside, the gear shaping on collar inner side surface is made to be slipped in groove along teeth groove, when the inner arc face of slot contacts with the upper end arc surface of fixed block, fixed block pressurized is retracted in cavity, spring pressurized, now just can dismantle connecting head and connecting tube, realize easy disassembly with this.

The beneficial effects of the utility model are: the utility model, when connecting tube and connecting head are assembled, connects without the need to using screw thread thread, long service life, and conveniently, anti-leakage is better for mounting or dismounting, maintenance.
