Description

A kind of anti-loose interface of hard locking of socket joint rubber sealing
Technical field
The present invention relates to pipe joint technical fields, the in particular to a kind of anti-loose interface of hard locking of socket joint rubber sealing.
Background technique
Plastics or plastics complex class blow-off line interface are there are many mode, and rigid connection technique excessively complicated difficult is constructed, more Face sedimentation, be displaced, expand with heat and contract with cold easily led in uncompensated situation interface or tube body damage.Spigot-and-socket rubber sealing belongs to Flexible interface installation is more convenient to be widely used, but interface watertightness is unsatisfactory.Mainly by coefficient of thermal expansion and contraction compared with Greatly, since the nose balance that the temperature difference generates easily causes interface loose, de- before backfill;Backfill is to pine, de- caused by interface disturbance;Sedimentation Lead to bellmouth and bellmouth bearing strength and tensile strength deficiency by jackknifing and pull risk, the displacement of bellmouth socket leads to underlapped portion Point too low compressive deformation of ring stiffness, these phenomenons lead to that interface is loose, de-, deformation causes interface leakage main cause.Cause life, Pharmacy, chemical industry, industrial and mining enterprises' sewage pipe are generated to ecology and environment because of interface Leakage for Groundwater and Zinc fractions long-term pollution Great influence.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of locking uncouplings of hard locking of socket joint rubber sealing Mouthful, have the advantages of bell and spigot stable connection, solves the problems, such as that present bell and spigot on the market is easy to appear and loosen.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:
A kind of anti-loose interface of hard locking of socket joint rubber sealing, comprising: the bellmouth of tube body one and the socket of tube body two, it is described Bellmouth outer wall is equipped with several radially-arranged annular convex platform studs, is equipped with several axial directions point between the annular convex platform stud The straight line boss stud of cloth, bellmouth interior side port position are equipped with the retaining boss for protruding from inner wall surface, and the retaining is convex The bellmouth retaining contact surface and bellmouth inner wall of platform are at right angles or oblique angle, retaining boss openings end outside are equipped in horn-like expansion Mouth inclined-plane, the bellmouth is interior to be equipped with bellmouth insertion limit only platform, and the insertion, which limits, stops platform to the displacement between retaining contact surface For socket axial direction displacement space, the socket is ported to be equipped with annular convex platform one, and one open end of annular convex platform is equipped with cooperation It is flared the tapered undergauge inclined-plane on inclined-plane, one other end of annular convex platform connects annular convex platform two, and the annular convex platform two leans on Nearly annular convex platform one end is equipped with two inclined-plane of annular convex platform, and the socket retaining contact surface and jack surfaces of the annular convex platform two are in straight Angle or oblique angle, the receptacle wall are equipped with several annular convex platform three, and the annular convex platform three is equipped with far from the ported end of socket Three slope of annular convex platform, the socket and one junction of tube body, outer wall are equipped with epipodium stiffness annular convex platform, the epipodium Stiffness annular convex platform close to three side of annular convex platform be equipped with socket insertion limit stop platform, the epipodium stiffness annular convex platform and only Move back the reinforcement block that metal or nonmetallic materials are lining on the inside of boss.
Further, the tube body one and two excircle winding section of tube body are circular stud.
Further, the retaining boss internal diameter is less than bellmouth internal diameter.
Further, two outer diameter of annular convex platform is greater than one outer diameter of annular convex platform, and two outer diameter of annular convex platform, which is greater than, to be held The retaining boss internal diameter of mouth is equipped with aprons slot between the annular convex platform one and annular convex platform two, installation is close in the aprons slot Seal rubber ring.
Further, the annular convex platform three is adjacent with annular convex platform two, and three outer diameter of annular convex platform is less than stopping for bellmouth Move back boss internal diameter.
The invention has the benefit that
Straight line boss stud of the present invention, solves socket hoop stiffness and flexural strength is insufficient;One open end of annular convex platform is set There is the tapered undergauge inclined-plane on cooperation flaring inclined-plane, abutting joint is difficult when solution bellmouth socket has ellipse;Retaining boss openings It is in trumpet flare inclined-plane that end outside, which is equipped with, is inserted into convenient for socket;Annular convex platform three is equipped with convex annular far from the ported end of socket Three slope of platform prevents from being formed retaining step and bellmouth, socket is hindered to move freely in displacement space;The socket and tube body one are handed over Meet place, outer wall is equipped with epipodium stiffness annular convex platform, the closed Problem of Failure of interface sliding mistake circle deformation, cushion rubber after solution installation It is inserted into bellmouth after being packed into sealing rubber ring in slot, expands bellmouth retaining boss, it is convex that socket annular convex platform two passes through bellmouth retaining After platform, bellmouth retaining boss restores, and contacts using the diameter difference of bellmouth retaining boss and annular convex platform two, and by bellmouth retaining Face and the mutual retaining locking of socket retaining contact surface realize anticreep mouth function, solve interface and are loosely displaced easily de- mouth leakage problems. Two inclined-plane of socket annular convex platform solves the resistance of socket insertion bellmouth, rapid wear ring sealing rubber ring when annular convex platform two is rectangular.
