Description
Technical field
The invention belongs to pipe joint technical field, refer in particular to a kind of Multifunctional quick joint.
Background technique
Publication No. is that CN102705615A discloses a kind of rapid pipe joint, it comprises: hollow shell, annular ledge, seal ring, pressure ring, latch circle, ejector sleeve and ejector sleeve overcoat is disposed with vertically in hollow shell, seal ring is pressed on annular ledge inside by pressure ring, described latch circle is arranged on one end that described pressure ring deviates from seal ring, described ejector sleeve one end abuts on latch circle, and described ejector sleeve overcoat to be socketed on ejector sleeve and to be linked together by described pressure ring and annular ledge.In this technology, only body directly need be inserted ejector sleeve, latch circle meeting automatic clamping body, but this technology exists following shortcoming: when 1. body inserts ejector sleeve, need press in ejector sleeve all the time, open to keep latch circle, the body otherwise the latch of latch circle can rub, meanwhile, need apply larger power, body is made to be forced through seal ring, this design makes body and rapid pipe joint assembling comparatively difficulty, and sealing effect is general, and the working life of latch circle and seal ring is low; 2., after body and rapid pipe joint are assembled, body and rapid pipe joint just can not relatively rotate, and make the adaptive surface of rapid pipe joint narrower; 3., after body and rapid pipe joint assembling, body can not be observed and whether insert and put in place, can only judge according to the experience of operator, make connection there is potential safety hazard; 4. rapid pipe joint and body error is in the fabrication process inevitable, and the degree of tightness between body and rapid pipe joint can not adjust, and therefore, this rapid pipe joint all has higher requirement to outer tube diameter and material, and fitting surface is narrower.
Summary of the invention
The object of this invention is to provide a kind of structure simple, safe and reliable, sealing is high, mounts and dismounts convenient and swift, adapts to wide, the Multifunctional quick joint that degree of tightness is adjustable.
The object of the present invention is achieved like this: Multifunctional quick joint, comprise valve body, valve body is provided with the plural incoming end inserted for body, incoming end is provided with step hole, position-limiting action can be played to body, wherein, described incoming end is provided with locking cap, locking cap, wedging cover and seal ring; Described locking cap is sheathed on described wedging and puts, and is provided with locking mechanism between locking cap and described locking cap; Described wedging cover is in claw structure, and when described locking cap and described locking cap relatively rotate, described locking mechanism makes described wedging overlap contraction or open, and realizes the fixing of body and dismounting; Described seal ring is arranged on the step surface of step hole; When seal ring is compressed by wedging cover and is out of shape, itself and stretch into the tube wall liquid sealing of described incoming end.
According to upper described Multifunctional quick joint, wherein, the concrete structure of described locking mechanism is: described locking cap is provided with bar-shaped trough, pin is provided with between described locking cap and locking cap, described pin one end embeds in described bar-shaped trough, when described locking cap relatively rotates with locking cap, described bar-shaped trough slides for guide rail spiral with described pin, completes moving axially of locking cap.
According to upper described Multifunctional quick joint, wherein, the outer wall of the locking end of described wedging cover is provided with projection, rotation lock cap, locking cap moves axially and expression lobes, when described projection enters described locking cap, described wedging cover shrinks, and completes fixing body.
According to upper described Multifunctional quick joint, wherein, the inwall of the end that described locking cap and described projection act on is provided with inclined-plane, when described projection is extruded, can enter described locking cap smoothly along inclined-plane, when rotation lock cap fixes body, more laborsaving.
According to upper described Multifunctional quick joint, wherein, the inwall of the locking end of described wedging cover is provided with latch, and during wedging cover locking body, latch is gripped on body, more firmly can fix body, prevents from coming off.
According to upper described Multifunctional quick joint, wherein, the afterbody of described wedging cover is provided with and stops circle, when needing body to extract from incoming end, rotate backward locking cap, locking cap is outwards moved axially, by stopping the stop of circle to wedging cover, locking cap and wedging cover is facilitated to depart from fast.
According to upper described Multifunctional quick joint, wherein, described seal ring and described wedging are provided with metal washer between overlapping, and avoid wedging cover directly to contact with seal ring, cause wearing and tearing, reduce sealing or lock ability.
According to upper described Multifunctional quick joint, wherein, described valve body is provided with observation body and whether inserts the visual window put in place, described visual window is positioned on the annular groove in the middle part of described valve body.
According to upper described Multifunctional quick joint, wherein, described annular groove is arranged with transparent sealing cover.
The present invention gives prominence to compared to existing technology and useful technique effect is: the present invention coordinates with body simply, after only body need being inserted incoming end, rotational lock cap, just can realize the fixing of body and sealing, and during the contraction of wedging cover, tightly be wrapped in body, area of contact is quite large, difficult drop-off, also not easily body is scratched, it is easy and simple to handle, good airproof performance, safe and reliable; Cooperation degree of tightness between the present invention and body is adjustable, rotatable tube before locking, adjustment body and the angle of docking between body, the elasticity can fixed according to the thickness adjustment of body after locking, lower to the requirement of outer tube diameter and material.Whether the design of visual window of the present invention, directly can observe body and insert and put in place, avoids inserting not in place, fixing insecure, cause and come off.
