Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly, it is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
It is as Figure 1-Figure 4: a kind of PP pipe of stable connection anticreep, including the first tube body 1, the second tube body 2, sealing nut
5, rubber ring 6 and screw 7.The outer right wall of first tube body 1 is equipped with screw thread 10, and inner wall is equipped with multiple be parallel to each other
Taper concave ring 8, and the taper of the taper concave ring 8 gradually increases from left to right, the screw thread 10 on 1 outer wall of the first tube body is left
Side is additionally provided with the first stop collar 3.The left side outer wall of second tube body 2 is equipped with and identical screw thread on 1 outer wall of the first tube body
10, and the right side of screw thread 10 is equipped with the second stop collar 4, the outer tube diameter at 2 screw thread 10 of first tube body 1 and the second tube body is small
Outer tube diameter in 10 left and right sides of screw thread.The left side of second tube body 1 is equipped with connecting tube 9, on the outer wall of the connecting tube 9
Equipped with the tapered protrusion 11 to match with the upper conical concave ring 8 of 1 inner wall of the first tube body, and the taper of the tapered protrusion 11 is past from a left side
The right side gradually increases, and the cone of the taper concave ring 8 and tapered protrusion 10 is towards left side.Second tube body 2 will be by that will connect
Pipe 9 is placed in the first tube body 1 connection realized with the first tube body 1, and the junction of first tube body 1 and the second tube body 2 is set
There is sealing nut 5, the two sides of the sealing nut 5 are equipped with rubber ring 6, and the rubber ring 6 and the tube body of 10 two sides of screw thread are mutual
It resists, four threaded holes 12 is additionally provided on the end face of the sealing nut 5, and four threaded holes 12 are with the center of circle of sealing nut 5
Centered on, it is respectively distributed in 180 ° on the both sides of the face of sealing nut 5, first stop collar 3 and the second stop collar 4 pass through
Screw 7 is connect with the threaded hole 12 of sealing nut 5, and the sealing nut 5 and screw 7 are stainless steel.
Its working principles are as follows: sealing nut 5 is spun on the screw thread 10 of the first tube body 1 when connection, then by the second pipe
The connecting tube 9 of body 2 is inserted into the inner wall of the first tube body 1, and in the same precession sealing nut of screw thread 10 on the second tube body 2, by
Cone is equipped with towards left taper concave ring 8 in 1 inner wall of the first tube body, and connecting tube 9 is equally convex towards left taper equipped with cone
It rises, so connecting tube 9 can be easier when being inserted into the first tube body, simultaneously as the taper of taper concave ring 8 and tapered protrusion 11
It gradually increases from left to right, so 9 right end of connecting tube, i.e. the first tube body 1 can be even closer with the junction of the second tube body 2,
Keep its anti-dropout effect more preferable.In addition, being additionally provided with sealing nut 5 in the junction of more than 1 second tube body 2 of the first tube body, further
The leakproofness of junction is enhanced, is additionally provided with rubber ring 6 in the left and right sides of sealing nut 5, limit can be played to sealing nut 5
Position effect.Finally, again by screw 7 by the first stop collar 3 on the first tube body 1, the second stop collar 4 on the second tube body 2 with
Threaded hole 12 on sealing nut 5 connects, and prevents sealing nut 5 from rotating at screw thread 10, avoids making because sealing nut 5 rotates
It is loosened at junction.
