Abstract
The invention discloses a sealing piece with good waterproof performance. The sealing piece comprises a round body, wherein a radial convex ring is arranged at the bottom end of the body; at least three arc grooves are formed in the top end surface of the body; an annular reinforcing ring is arranged on the side of the radial convex ring; a plurality of transverse reinforcing ribs are arranged on the annular reinforcing ring. The sealing piece is high in waterproof property, circumferential limiting property and sealing property.
Description
Technical field
The present invention relates to industrial part technical field, especially relate to the Sealing that a kind of water-proof performance is good.
Background technique
There is the Sealing that a kind of water-proof performance is good at present, comprise circular body, be provided with radial convex loop in the bottom of body, be provided with right angle chamfering at the top of body.In use, be embedded into the through hole of the pump housing, its radial convex loop is then close in the outerplanar of the pump housing.The top of body then offsets with the step surface in through hole, and because body top end face is plane, so circumferential spacing property is poor.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide the Sealing that a kind of water-proof performance is good, it is good that it has circumferential spacing property, the feature of good sealing effect.
To achieve these goals, the technical solution adopted in the present invention is: the Sealing that a kind of water-proof performance is good, comprise circular body, body bottom is provided with radial convex loop, the top end face of described body is provided with three arc grooves, the side of described radial convex loop is provided with annular stiffening ring, and annular stiffening ring is provided with several cross reinforcings.
Wherein, the side of described radial convex loop is provided with some annular stiffening rings, and annular stiffening ring is provided with several cross reinforcings.
Wherein, the top end face of described body is provided with at least three polygonal grooves or scalloped recess.
After adopting said structure, the present invention is compared to the prior art advantageously: it comprises circular body, body bottom is provided with radial convex loop, the top end face of described body is provided with three arc grooves, the side of described radial convex loop is provided with annular stiffening ring, annular stiffening ring is provided with the body of several center holes, body bottom is provided with radial convex loop, the top end face of described body is provided with three arc grooves, the side of described radial convex loop is provided with annular stiffening ring, annular stiffening ring is provided with several cross reinforcings, the present invention is by being provided with three arc grooves at the top end face of body, and be provided with annular stiffening ring in the side of radial convex loop, the male cooperation of step surface during use in arc groove and pump housing through hole embeds, and radial convex loop is close to by the outerplanar of annular stiffening ring and stiffening rib and the pump housing, the spacing property of such circumference is good, good sealing effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is another structural representation of the present invention.
Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
As depicted in figs. 1 and 2: the Sealing that a kind of water-proof performance is good, comprise circular body 1, body 1 bottom is provided with radial convex loop 2, the top end face of described body 1 is provided with three arc grooves 3, the side of described radial convex loop 2 is provided with annular stiffening ring 6, annular stiffening ring 6 is provided with several cross reinforcings 5, also the side of described radial convex loop 2 can be provided with some discrete annular stiffening rings 6, annular stiffening ring 6 is provided with several cross reinforcings 5, wherein, the top end face of described body 1 is provided with three polygonal grooves or scalloped recess, certainly also can be other shape, the present invention is by being provided with three arc grooves 3 at the top end face of body 1, and be provided with annular stiffening ring 6 in the side of radial convex loop 2, during use, arc groove 3 embeds with the male cooperation of the step surface in pump housing through hole, and radial convex loop 2 is close to the outerplanar of the pump housing by annular stiffening ring 6 and stiffening rib 5, the spacing property of such circumference is good, good sealing effect.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
Claims (3)
