Abstract
The invention discloses an automobile dismounting preventing quick coupling device. The automobile dismounting preventing quick coupling device comprises a quick coupling connected in a sealing manner. A one-way snap spring is arranged at the position of the connecting end of a shell of the quick coupling and composed of a clamping ring and a clamping claw which is installed on the inner circle of the clamping ring and inclines towards the interior of the shell. During injection molding of the shell, the clamping ring is embedded in the connecting end of the shell in the form of an insert. According to the automobile dismounting preventing quick coupling device, rapid inserting and pulling are achieved on the premise that using safety indexes of an automobile are achieved; and the assembly manner of an automobile pipe fitting is changed, dismounting is prevented, the work efficiency of workers is improved, and the integrated cost of the whole automobile is reduced.
Description
Technical field
The present invention relates to automobile technical field, particularly to a kind of anti-dismounting snap joint connecting device of automobile being applied to automotive oil system and air-channel system.
Background technology
In in the past few decades, what automobile pipeline system was commonly used is all ferrule-type compression joint, needs manual tightening, assemble loaded down with trivial details when this pipe joint is installed on automobile general assembly line, and poor sealing performance.Along with heavy-duty, intellectuality, automatic assembling automotive engineering requires and the stepping up of state's laws regulation, all kinds of pipeline of automobile becomes increasingly complex, particularly inside longitudinal beam, the narrow space place such as enging cabin, electrical harness, all kinds of pipelines etc. are often crowded together, and legacy card sleeve type pipe joint is all difficult to meet design requirement in air-tightness, assembling interchangeability etc..In the case, it is necessary to use and can bear higher sealing and the better novel speed pipe of assembling.Fast spigot joint changes the tradition assembling mode screwed up with a wrench, and with flexible pipe and the direct grafting of joint, not only saves cost of labor and equipment loss cost, also improves efficiency of assembling, saves assembly space；Also solve the links such as ferrule-type compression joint and valve body simultaneously and locally lie in partially long phenomenon.
Domestic automobile pipe-line system pipe joint only exists in the research and development trial period, and therefore development and application has the performance car quick coupling of China's independent intellectual property right and has important practical significance.Because Quick-acting type mounting joint is without instrument, saving time and reduction expense can realize Automated assembly, it is particularly well-suited to automatic assembly line and is easy to automated production, its compact conformation, it is suitable for the occasion that assembly space is limited especially, integrated sealing structure, best sealing effectiveness uses so being widely used in a variety of applications at auto industry field.
But current is domestic or the snap joint used in the world is all easy for installing and also allows for dismounting, and some are not just allowed the pipeline of dismounting to connect and cause potential potential safety hazard by this.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of anti-dismounting quick coupling device of automobile not only can quickly installed but also prevent and remove.
The present invention is to solve that its technical problem be the technical scheme is that a kind of anti-dismounting quick coupling device of automobile, including the snap joint being tightly connected, at the link place of the housing of snap joint, one unidirectional jump ring is set, described unidirectional jump ring is by snap ring and is arranged on snap ring inner circle and forms to the claw that housing is tilted, and described snap ring is arranged in the link of housing with the form of inserts when housing injection mo(u)lding.
As a further improvement on the present invention, it is additionally provided with a sealing ring in the link of described housing.
The invention has the beneficial effects as follows: the anti-dismounting quick coupling device of automobile of the present invention achieves fast insert-pull under the premise meeting automobile safety in utilization index；Change the assembling mode of automobile pipe fitting, it is prevented that dismounting, improve workman's work efficiency, reduce car load integrated cost, and the assembling simultaneously solving the existence of existing ferrule-type compression joint is difficult, installation is subject to the problems such as space restriction；Curved logical, threeway and four-way union achieve rotatability.Meet pipe-line system entirety gas tightness requirement, solve existing common pipeline systematic pipeline and arrange chaotic and the problems such as limited are installed；The pipe joint of equivalent specifications and quantity, than existing ferrule-type compression joint weight saving 30%, reduces car load energy consumption, decreases toxic emission, meets national energy-saving environmental requirement, can reach the up-to-date draining technology standard of commercial car country.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Figure indicates: 1-snap joint housing；The unidirectional jump ring of 2-；3-snap ring；4-claw；5-sealing ring.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
In use joint can be connected with pipeline by user when without any instrument.
Fig. 1 illustrates a kind of embodiment of a kind of automobile of the present invention anti-dismounting quick coupling device, including the snap joint being tightly connected, one unidirectional jump ring 2 is set at the link place of the housing 1 of snap joint, described unidirectional jump ring 2 is by snap ring 3 and is arranged on snap ring inner circle and forms to the claw 4 that housing is tilted, described snap ring 3 is arranged in the link of housing 1 when housing 1 injection mo(u)lding with the form of inserts, is additionally provided with a sealing ring 5 in the link of described housing 1.
Increase by one in snap joint and can play the unidirectional jump ring preventing removing function.This jump ring can when joint housing injection mo(u)lding the form of inserts synchronously complete installation location, in use, when joint is installed by forward unidirectional jump ring claw can because stress to surrounding open Shi Nei garden diameter become big allow to access section by and be in close contact with insertion end.Once occur that inserting end opposite direction moves, the angle by unidirectional jump ring determines, claw can, because stress diminish to central reduction Shi Nei garden diameter, not allow to insert end adverse movement.Now complete its function preventing from removing.
Claims (2)
