Abstract
The invention relates to a dropping-resistant washer which comprises a washer body. A plurality of protrusions are further arranged on at least one end surface of the washer body and are made of flexible materials, openings are formed in the upper ends of the protrusions, the lower ends of the protrusions are sealed, the upper end surfaces and the lower end surfaces of the protrusions are coaxial circular surfaces, the diameters of the upper end surfaces of the protrusions are larger than those of the lower end surfaces of the protrusions, and the lower end surfaces of the protrusions are embedded in the washer body. The dropping-resistant washer has the advantages that air in the protrusions is compressed in usage procedures of the washer, and the washer can be firmly fixed onto a connecting piece under the effect of internal and external pressure difference and accordingly is difficult to lose or drop.
Description
Technical field
The present invention relates to a kind of packing ring, relate in particular a kind of packing ring of difficult drop-off.
Background technique
In prior art, the general and fastening piece of packing ring is used in conjunction with, and common fastening piece is screw, bolt; And common packing ring comprises packing ring body; Packing ring body is rounded; On packing ring body, be provided with through hole; Conventionally packing ring body is made by rubber.In real work, this packing ring easily comes off, and loses, and affects the normal practicality of fastening piece.Chinese utility model patent CN 103775472 A have announced the thin packing ring of a kind of permanent magnetism, comprise packing ring body and be embedded in the permanent magnetism packing ring in packing ring, utilize the effect of electromagnetism to make packing ring difficult drop-off and loss, although also can reach fastening effect, but the scope of application is narrower, there is the use narrow limitation of self.
Summary of the invention
In order to overcome above-mentioned deficiency, the technological scheme that the present invention solves is to provide a kind of packing ring of difficult drop-off.
To achieve these goals, the present invention adopts following technological scheme:
A kind of packing ring of difficult drop-off, comprise packing ring body, on at least one end face of body of described packing ring, be also provided with a plurality of protruded objects, described protruded object is comprised of flexible material, the sealing of upper end open lower end, upper and lower end face is coaxial disc, and upper-end surface diameter is greater than lower end surface diameter, and lower end surface is embedded in packing ring body.
Preferably, on described packing ring body, be also provided with a penetration hole.
Preferably, the upper and lower end face of described packing ring body is equipped with protruded object.
Useful technique effect of the present invention is:
The packing ring of a kind of difficult drop-off of the present invention, a plurality of protruded objects have been adopted, because this protruded object is comprised of flexible material, the sealing of upper end open lower end, in the using process of packing ring, the air during protruded object is interior is compressed, and inside and outside pressure difference is fixed on link by packing ring firmly, so be difficult for losing, come off.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technological scheme of the present invention is further described in detail.
Fig. 1 is schematic cross-section of the present invention.
In figure: 1, packing ring body, 2, protruded object, 3, axial hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further set forth:
A kind of packing ring of difficult drop-off, comprise packing ring body, on two end faces of body of packing ring, be equipped with 2 protruded objects, protruded object consists of flexible material, the sealing of upper end open lower end, and the upper and lower end face of protruded object is coaxial disc, upper-end surface diameter is greater than lower end surface diameter, and lower end surface is embedded in packing ring body.The packing ring of difficult drop-off of the present invention, has adopted a plurality of protruded objects, due to this protruded object upper end open lower end sealing, in the using process of packing ring, the air during protruded object is interior is compressed, and inside and outside pressure difference is fixed on link by packing ring firmly, so be difficult for losing, come off.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
