Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide a kind of rapid pipe joint of anti-self-fastening button misloading.
The utility model is realized by the following technical programs:
The rapid pipe joint of described anti-self-fastening button misloading, comprise housing, on housing, be symmetrical arranged self-fastening button mounting hole, on described housing cavity inner wall, be equipped with O RunddichtringO, seal ring and inner walls are sealed and matched, the outside of seal ring sets gradually outer back-up ring and self-fastening button, described self-fastening button is pegged graft and is arranged in housing cavity by mounting hole, it is characterized in that being provided with anti-misloading limit point on described mounting hole, the position of the corresponding mounting hole of self-fastening button is provided with the restraining groove being used in conjunction with anti-misloading limit point.Anti-misloading limit point and restraining groove are used in conjunction with, and can effectively prevent that self-fastening button is anti-loaded.
The rapid pipe joint of described anti-self-fastening button misloading, is characterized in that the one-body molded medium position that is arranged on mounting hole one side of described anti-misloading limit point.
The rapid pipe joint of described anti-self-fastening button misloading, is characterized in that described anti-misloading limit point is semicircle or isosceles triangle or square.
The rapid pipe joint of described anti-self-fastening button misloading, is characterized in that described seal ring has two, is inner seal ring and exterior seal ring, between inner seal ring and exterior seal ring, is equipped with inner shield ring.
The rapid pipe joint of described anti-self-fastening button misloading, is characterized in that described housing and the socket of pipeline joint are provided with seal ring.
The rapid pipe joint of the anti-self-fastening button misloading of the utility model, simple in structure, reasonable in design, due to the special tectonic of rapid pipe joint housing main body, in injection moulding process, molten loft can arrange protruding limit point on shell self-fastening button mounting point, after molding and forming, can strengthen this place's intensity, joint entirety pull-out force value is provided; Put and the cooperation of restraining groove by fiber, can effectively avoid the generation of the anti-loaded phenomenon of self-fastening button, reduce production process, increase work efficiency.
Brief description of the drawings
Fig. 1 is the utility model internal structure schematic diagram;
Fig. 2 is the utility model cross-sectional view;
In figure: 1-housing, 2-mounting hole, the outer back-up ring of 3-, 4-self-fastening button, the anti-misloading limit point of 5-, 6-restraining groove, 7-inner seal ring, 8-exterior seal ring, 9-inner shield ring, 10-seal ring.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, and provides embodiment.
As shown in Figure 1-2, the rapid pipe joint of the anti-self-fastening button misloading of the utility model, comprise housing 1, on housing 1, be symmetrical arranged self-fastening button mounting hole 2, on housing 1 cavity inner wall, be equipped with O RunddichtringO, O RunddichtringO is fixed on housing 1 cavity inner wall boss, O RunddichtringO coordinates with housing 1 inner wall sealing, O RunddichtringO comprises inner seal ring 7 and exterior seal ring 8, between inner seal ring 7 and exterior seal ring 8, be equipped with inner shield ring 9, inner seal ring 7 and exterior seal ring 8 are kept apart with inner shield ring 9, make two seal rings have corresponding activity space, avoid occurring rubber matrix bonding phenomenon, the outside of exterior seal ring 8 sets gradually outer back-up ring 3 and self-fastening button 4, in order to seal ring is inwardly fixed, exterior seal ring 8 adopts fluorine silicon synthetic rubber, strengthens mechanical property, prevents that it is at air aging, seal ring and inner shield ring 9 are firmly fixed in housing 1 by the elastic bayonet lock device of outer back-up ring 3, can not produce the phenomenons such as seal ring comes off, displacement and produce, and have ensured greatly the Security of sealing.For further enhanced leaktightness effect, be provided with seal ring 10 in housing 1 and the socket of pipeline joint.Self-fastening button 4 is pegged graft and is arranged in housing 1 cavity by mounting hole 2, anti-loaded in order to prevent self-fastening button 4, on mounting hole 2, be provided with anti-misloading limit point 5, the position of the corresponding mounting hole 2 of self-fastening button 4 is provided with the restraining groove 6 being used in conjunction with anti-misloading limit point 5, the one-body molded medium position that is arranged on mounting hole 2 one sides of anti-misloading limit point 5, anti-misloading limit point 5 can be arranged to semicircle or isosceles triangle or square, and restraining groove 6 correspondences are arranged to semicircle, isosceles triangle or square.Arrange after anti-misloading limit point, self-fastening button can only be installed towards correct direction, and the generation that can stop anti-loaded phenomenon completely in addition, by the anti-misloading limit point 5 of projection is set, also can be avoided the embrittlement of mounting hole 2, gains in strength, and improves the pull-out force value of joint entirety.
When installation, only self-fastening button 4 directly need be pressed into the position of housing 1 mounting hole 2, owing to being provided with anti-misloading limit point 5, can avoid self-fastening button 4 anti-loaded, after installing, when another pipeline ABAP Adapter is that male connector inserts in rapid pipe joint, because self-fastening button 4 has certain elasticity, coordinate buckle fastener two joints can be linked together, then pull back, go bail for and be in place, rapid pipe joint just plays a role like this, when repair demolition, need only and first advance male connector, then pin the buckle button at self-fastening button 4 two ends, make to open in the middle of self-fastening button 4, just can easily extract joint and carry out maintenance and inspection work.In whole installation and unloading process, owing to being provided with anti-misloading limit point 5 and corresponding restraining groove 6, the anti-misloading limit point 5 of protrusion, compared with protruding housing is not set, is difficult for embrittlement herein, and intensity enhancing can improve the pull-out force value of joint entirety.
