Abstract
The invention relates to the technical field of pipe connection equipment, in particular to a fast-to-connect and convenient-to-dismount pipe joint. The problem that an O-shaped ring is liable to suffer qualitative change and therefore affects sealing during the process that conventional pipes are connected is solved. The pipe joint comprises a straight pipe with openings at two ends. A first clamping groove, a first convex table and a second clamping groove are sequentially formed from inside to outside at each end of the straight pipe, an O-shaped ring is arranged in each first groove, a clamp spring is clamped on each first step, and a cap body is arranged in each second groove, wherein each cap body comprises an inner core and a ringent clamp spring, wherein the ringent clamp spring which is clamped in the second groove is sleeved with the inner core in the middle. According to the fast-to-connect and convenient-to-dismount pipe joint, the cost is largely lowered and the leakage proof performance is good.
Description
Technical field
The present invention relates to pipe and connect equipment technical field, particularly relate to joint for pipe and the processing technology thereof of a kind of quick dismounting easy to connect.
Background technology
Product in the market is owing to cannot capture injection mo(u)lding problem, therefore when pipe connects, need one by after tube to tubesheet, put into O again other end to be processed, owing in mould, temperature is high, make generation qualitative change under O high temperature, having a strong impact on sealing effectiveness, directly connecting thus affecting two pipes.
Summary of the invention
The present invention is to solve that when tradition pipe connects, O is susceptible to the problem that qualitative change impact seals, it is provided that the joint for pipe of a kind of quick dismounting easy to connect.
For solving above-mentioned technical problem, the present invention takes techniques below scheme: the joint for pipe of a kind of quick dismounting easy to connect, straight tube including two open ends, the two ends of straight tube are from inside to outside sequentially provided with the first draw-in groove, the first boss and the second draw-in groove respectively, being provided with O in first draw-in groove, on first step, card has jump ring, is provided with lid in the second draw-in groove, described lid includes inner core and opening jump ring, is cased with the opening jump ring being stuck on the second draw-in groove in the middle part of inner core.O is built-in, O is provided with corresponding draw-in groove, can effectively prevent not being put into the factors such as position due to O and cause that pipe insertion meets place soon by O compressive strain, more some is in operation, O puts into joint, due to carelessness in installation process, O flower falls to the ground and does not also know, directly results in and does not put O and pipe leakage.
Described straight tube, inner core and opening jump ring are nylon or polyformaldehyde.
The described upper and lower both sides of opening jump ring are provided with the step that may be stuck on straight tube inwall, and opening jump ring is provided with the opening of longitudinal fracture.
The external diameter that described opening jump ring is topped bar is be more than or equal to straight spout diameter and less than straight tube external diameter.
Inner core is positioned at one end of opening jump ring and is provided with a circle convex hole, and the external diameter of described convex hole is be more than or equal to the internal diameter of straight tube, and convex hole is stuck in inside opening jump ring.Convex hole is the effect of release straight tube, and convex hole can allow hands have bigger active force to push away inward, and the active force of such hands is applied to convex hole, and convex hole is located on inner core, and inner core pressure jump ring, jump ring struts, and plastic tube just can be pulled out.
Opening jump ring is fracture design, convex hole external diameter is be more than or equal to straight spout diameter, and opening jump ring processes due to fracture, post-rift opening jump ring external diameter is slightly less than straight spout diameter, and therefore opening jump ring can be snapped in lid draw-in groove by straight tube mouth, after putting into lid draw-in groove, owing to opening jump ring ruptures, plastics itself have elasticity, can strut a part outward, and what therefore lid can be stable is stuck in draw-in groove.
Described jump ring includes annulus, and annulus inner ring is provided with a circle latch, and described latch forms the internal diameter external diameter less than pipe to be connected of internal ring.
The material of described jump ring is rustless steel.Rustless steel jump ring is placed on the first boss of correspondence, and rustless steel jump ring is rotatable, needs or user demand owing to installing, pipe needs after inserting joint to adjust, and the rustless steel jump ring of present invention design is movable design, after pipe is plugged, can rotate freely so that install and use convenient.
Described inner core inner ring is provided with the cap of the annular that can move along inner core inner ring, and the internal diameter of cap is be more than or equal to the external diameter of pipe to be connected.Product can be facilitated directly to dismantle, and cap pushes inward, and vinyl cover withstands stainless steel clamp so that stainless steel clamp is opened toward both sides, unclamps pipe, makes pipe to take out.
Described straight tube inner ring is provided with circle second boss.Pipe inserts straight tube and can be blocked to middle part, it is possible to play certain leakproof effect.
The processing technology of the joint for pipe of quick dismounting easy to connect, specifically comprises the following steps that
1) injection moulding, straight tube body preliminarily forms, and straight tube body is carried out outdoor rain drop erosion and exposes to the weather;
2) polish, cuts out first draw-in groove at the two ends in straight tube body and the second draw-in groove;
3) lathe process opening jump ring, fracture processes, and reams sub-fraction opening part, processes opening jump ring inner side step;
4) assemble finished product, put into O, rustless steel jump ring, opening jump ring, is inserted into inner core, owing to inner core convex hole one end is arc, arch section passes through opening jump ring step part so that opening jump ring outwards struts, until convex hole passes through, opening jump ring bounces back again, and in running, hydraulic pressure makes the process that pipe walks toward outside, rustless steel jump ring blocks pipe, and lid withstands stainless steel clamp, and opening jump ring step blocks convex hole, opening jump ring is stuck in corresponding draw-in groove, and pipe is blocked in whole realization.
Compared with prior art, the present invention connects weight compared with copper pipe and significantly alleviates, and cost is substantially reduced.
Leakproof is good, and due to currently used based on nylon, early stage is through exposing to the weather, and rainwater so that toughness of products is greatly improved, after tested, in sealing property, the hydraulic pressure that can bear is better than copper products.
And assemble simple, injection mo(u)lding, save significant portion artificial cost, be greatly improved the product rate of output.
Product quality is more stable.
