Description

Waterproof spring washer

Technical Field

The utility model relates to a waterproof spring washer belongs to spring washer technical field.

Background

The spring washer is widely applied to bearing and non-bearing structures of common mechanical products, and has the characteristics of low cost, convenient installation and suitability for parts with frequent assembly and disassembly. Spring washers are commonly called spring washers in the screw industry. The material of it is stainless steel and carbon steel. At present, establish through overlapping metal spring packing ring and sealing washer each other on waterproof motor and form, utilize the waterproof nature of sealing washer to solve the problem of intaking, existing locking effect has waterproof effect again, but spring packing ring and sealing washer establish the back through the cover, and it hardly produces relative displacement in the bolt tightening process, and then the sealing washer is easily worn and torn in the bolt-up in-process, influences water-proof effects.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a waterproof spring washer to solve the problem that proposes in the above-mentioned background art, the utility model discloses modular assembly, the abrasionproof decreases, has waterproof function.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a waterproof spring washer, includes the packing ring body, packing ring body upper end is personally submitted annular equidistance and is seted up three arc wall one and three arc wall two of group, three groups arc wall one and three arc wall two of group arrange in turn, packing ring body up end installation sealing washer one, sealing washer up end installation sand grip one, sand grip one is inserted in arc wall one, end installation sealing washer two under the packing ring body, two up end installation sand grip two of sealing washer, sand grip two is inserted in arc wall two.

Furthermore, the first protruding strip and the first sealing ring are of an integrally formed structure, and the second protruding strip and the second sealing ring are of an integrally formed structure.

Further, the length of the first protruding strip is smaller than the depth of the first arc-shaped groove, and the length of the second protruding strip is smaller than the depth of the second arc-shaped groove.

Furthermore, the first sealing ring and the second sealing ring are the same in specification, and the first arc-shaped groove and the second arc-shaped groove are the same in specification.

Further, three groups are all installed to sand grip one and sand grip two, three groups the sand grip one is annular equidistance and installs terminal surface under the sealing washer, three groups sand grip two is annular equidistance and installs at two up end of sealing washer.

The utility model has the advantages that: the utility model discloses a waterproof spring washer, because of the utility model discloses add sand grip one, arc wall two and sand grip two, this design is through with sand grip one and sand grip two respectively assign in arc wall one and arc wall two, and then at the bolt tightening in-process, sealing washer one and sealing washer two drive sand grip one and sand grip two slide respectively in arc wall one and arc wall two under the effect of extrusion force, thereby sealing washer one and sealing washer two produce relative displacement with the packing ring body, sealing washer one and sealing washer two rotate along with the nut on the bolt promptly, reduce the probability that sealing washer one or sealing washer two damaged because of the friction.

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of a waterproof spring washer according to the present invention;

FIG. 2 is a sectional view taken along line A-A of a waterproof spring washer according to the present invention;

in the figure: the gasket comprises a gasket body 1, a sealing ring I2, a convex strip I3, an arc groove I4, an arc groove II 5, a sealing ring II 6 and a convex strip II 7.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a waterproof spring washer comprises a washer body 1, wherein three groups of arc-shaped grooves I4 and three groups of arc-shaped grooves II 5 are arranged on the upper end surface of the washer body 1 in an annular equidistant mode, the three groups of arc-shaped grooves I4 and the three groups of arc-shaped grooves II 5 are alternately arranged, a sealing ring I2 is arranged on the upper end surface of the washer body 1, a convex strip I3 is arranged on the lower end surface of the sealing ring I2 and is inserted in the arc-shaped grooves I4, a sealing ring II 6 is arranged on the lower end surface of the washer body 1, a convex strip II 7 is arranged on the upper end surface of the sealing ring II 6 and is inserted in the arc-shaped grooves II 5, when the waterproof spring washer is used, the sealing ring I2 and the sealing ring II 6 are respectively placed on the upper side and the lower side of the washer body 1, the convex strip I3 on the sealing ring I2 is inserted in the arc-shaped grooves I4 and the convex strip II 7 on the sealing ring II 6 is inserted in, the bolt is established on the bolt and the bolt is at the screw-up in-process to packing ring body 1 cover, and sealing washer one 2 or two 6 produce relative slip with packing ring body 1 under the effect of extrusion force, and then sand grip one 3 slides along arc wall one 4 or sand grip two 7 slides along arc wall two 5 to reduce sealing washer one 2 or two 6 because of being difficult to slide and damaged, be favorable to improving water-proof effects.
