Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lining plastic pipe seal ring, and it is convenient that it can make seal ring install, little by resistance, has more sealing effect.
The technical solution adopted in the utility model is as follows:
A kind of lining plastic pipe seal ring, comprise seal ring coil, the outer surface two ends of described seal ring coil are provided with raised ribs, described raised ribs with the outer surface of seal ring coil for basal plane is that oblique angle raises up, the direction, oblique angle of the raised ribs set by described seal ring coil outer surface two ends is contrary, the identical raised ribs in direction, described oblique angle is provided with several, and their external diameter varies in size.
The utility model varies in size solve seal ring by the large problem of resistance by arranging the identical raised ribs external diameter in direction, oblique angle, the layered structure that simultaneously difference of raised ribs external diameter is brought makes to be compacted bottom seal ring coil more fastening, and then more can improve the sealability of seal ring to tubing.
The identical raised ribs external diameter size in direction, described oblique angle increases progressively near seal ring coil port toward in.The similar chamfering of its effect of this structure is such, and being convenient to overlap has the tubing of seal ring to screw in another root tubing, and the difference of external diameter size makes the elastic strain of seal ring increase simultaneously, makes seal ring more be close to tubing wall, greatly improves the sealability of seal ring; The structure that raised ribs external diameter size is successively decreased from close seal ring coil port toward in or other different size is arranged in addition can make the elastic strain of seal ring increase and then improve sealing effect, just best to increase progressively the effect that this structure plays toward near seal ring coil port, certainly do not do unique restriction here, specifically arrange according to actual conditions.
The identical raised ribs in direction, described oblique angle has three, and be respectively the first raised ribs, the second raised ribs and the 3rd raised ribs from port toward in, the other end is provided with direction, an oblique angle four raised ribs contrary with first, second, and third raised ribs.
The other end of described seal ring coil outer surface is also provided with direction, an oblique angle five raised ribs contrary with the 4th raised ribs.
The contrary protrusion muscle in the utility model direction on the ear end face of seal ring coil can provide good elastic deformability, thus improves sealability.
Compared with prior art, the beneficial effect that the utility model has: the identical raised ribs external diameter in direction, oblique angle varies in size, and that seal ring can be made to install is convenient, little by resistance, and elastic strain is large, has more sealing effect.
