Abstract
The utility model relates to a fast coupling for air braking systems for automobile nylon pipes. Nylon pipes are applied widely in automobile braking systems, while with sleeve-type pipe coupling, which has defects such as inconvenience for assembly and low efficiency. Aiming to eliminate the defects, the utility model raise a fast coupling for air braking systems for automobile nylon pipes that has simple structure and enables the plug to be inserted directly into the coupling body to provide convenience for disassembly of the coupling body. The preferred technical proposal in the utility model is that an expansion circle (2) is arranged along the outer circle of the coupling body (1) that has one end shaped as a conical surface; a flexible hook ring (4) is arranged on a plug (5) with an O-shaped sealing ring embedded in the concave groove along the outer circle at one end; flexible hooks taking a shape of a overturned petal are distributed evenly on the circular wall of the flexible hook ring (4).
Description
One, technical field
The utility model relates to the brake system of car joint, especially vehicle nylon pipe air braking system rapid pipe joint.
Two, background technique
Automobile fuel feeding and braking system extensively adopt the nylon tube of price root, function admirable at present, to replace traditional metallic conduit.Pipeline at vehicle nylon pipe air braking system connects the linkage structure that still adopts traditional metallic conduit, and promptly Bite type fittings will use spanner when existing assembling, assembly space is again little, is awkward, and efficiency of assembling is low, deficiencys such as assembly quality is difficult to assurance, and labor intensity is big.Disclose " rapid pipe joint of a kind of vehicle nylon pipe air braking system " patented technology at number of patent application 02223142.0, had complex structure, deficiencys such as processing cost height.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, can directly plug be inserted in the fittings body body and the vehicle nylon pipe air braking system rapid pipe joint that goes out fittings body for convenience detach.
The technological scheme that the purpose of this utility model adopted is, including fittings body and plug forms, the fittings body cylindrical that the one end is the conical surface is equipped with piston ring, the plug that the outer round recessed of one end is embedded with the O RunddichtringO is equipped with the elastic hook ring, and the ring wall of elastic hook ring is evenly equipped with overhead kick lobe shape elastic hook.
The utility model, the ring wall of elastic hook ring are evenly equipped with 3-9 lobe shape elastic hook.
The utility model, the rapid pipe joint working principle: fittings body one end and vapour source are with being threaded, when plug one end is inserted in the fittings body the other end, the overhead kick lobe shape elastic hook of circumference uniform distribution is gradually by the conical surface spreading of fittings body front end, after elastic hook surpasses auger footpath, conical surface bottom, elastic hook restores to the original state, and elastic hook is blocked by the bottom surface of fittings body front end cone, guarantees that the plug that has the vehicle nylon pipe is difficult for transfering in fittings body.O RunddichtringO on the plug plays seal action, guarantees unlikely leakage under the automobile working pressure; Quick dismantlement work principle: plug be extracted in fittings body, can be with piston ring to the vehicle nylon tube side to propelling, at this moment, the overhead kick lobe shape elastic hook of circumference uniform distribution is forced outwardly spreading, when piston ring during near fittings body front end facies basialis pyramidis, the plug of band nylon tube just can be extracted in fittings body.
The utlity model has simple and compact for structurely, make simply, assembling, convenient disassembly alleviate assembling labor intensity, seal characteristics such as reliable.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model sectional structure schematic representation;
Sectional structure schematic representation when Fig. 2 is the utility model assembling;
Sectional structure schematic representation when Fig. 3 is the utility model dismounting.
Among the figure: 1-fittings body, 2-piston ring, 3-O RunddichtringO, 4-elastic hook ring, 5-plug, 6-nylon tube
Five, embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the plug 5 that fittings body 1 cylindrical that an end is the conical surface is equipped with the fluted O of the being embedded with RunddichtringO 3 of piston ring 2, one end cylindricals is equipped with elastic hook ring 4, and plug 5 the other ends are equipped with nylon tube 6.
Claims (2)
1, a kind of vehicle nylon pipe air braking system rapid pipe joint, including fittings body (1) and plug (5) forms, it is characterized in that an end is the fittings body of the conical surface (1) cylindrical and is equipped with piston ring (2), the plug (5) that the outer round recessed of one end is embedded with O RunddichtringO (3) is equipped with elastic hook ring (4), and the ring wall of elastic hook ring (4) is evenly equipped with overhead kick lobe shape elastic hook.
2, a kind of vehicle nylon pipe air braking system according to claim 1 rapid pipe joint is characterized in that the ring wall of elastic hook ring (4) is evenly equipped with 3-9 lobe shape elastic hook.
