Abstract
The utility model belongs to a field of waterproof sealing of electronic components, particularly relating to a tarpaulin which is used for the waterproof sealing of the electronic components manually contact with the outside world. The utility model consists of a rubber tarpaulin a, a hexagonal nut b, a washer c, a mask 1, an installing seat 2, a seal convex ring 3, a tarpaulin body 4, an installing groove 5, a beading edge 6, a beaded edge 7 and a pressed installing seat 8. The tarpaulin has the advantages that the tarpaulin is characterized by low manufacturing cost, simple and reasonable structure, reliable performance and convenient operation; the tarpaulin can work for a long time before the rubber is aged and can be widely applied to the tarpaulins with various usages such as the open-pit waterproofing, dust prevention and deepwater work, etc.
Description
Technical field
The utility model belongs to electronic original part waterproof sealing field, is specifically related to a kind of electronic original part that is used for and manually contacts the tarpaulin that waterproof sealing is used with extraneous, is specially adapted to the tarpaulin that deepwater work is used.
Background technology
The electronic original part that generally uses and the external world manually contact the tarpaulin that waterproof sealing is used at present, traditional tarpaulin, all take between rubber and nut, to connect with the bonding method of glue, this connecting mode exists and has used after a period of time, before rubber is also not aging, the phenomenon that occurs layering between rubber and the nut with the bonding position of glue, extraneous water can will cause electronic original part to cause the consequence that electronic original part is malfunctioning, burn out electronic original part because of the infiltration short circuit from the inside seepage in the slit at layering position.
Summary of the invention
The technical problem that the utility model will deblock provides compared with prior art a kind of, overcome deficiency of the prior art, provide a kind of construction cost low, rational in infrastructure, before rubber is also not aging, can work for a long time, and the tarpaulin of dependable performance waterproof and dustproof.
The utility model is achieved by the following technical programs, a kind of tarpaulin, be by rubber waterproof cover a, hexagonal (hexagon)nut b, packing ring c forms, its characteristics are: connecting between rubber waterproof cover a and the hexagonal (hexagon)nut b, be by packing ring c precompression of mount pad to rubber waterproof cover a, the mounting groove of the protruding circle of sealing of rubber waterproof cover a and hexagonal (hexagon)nut b is fitted like a glove and bear certain pressure, shape with the limit after the closing in limit riveting one-tenth closing in of hexagonal (hexagon)nut b makes the mount pad between rubber waterproof cover a and the hexagonal (hexagon)nut b, seal the shape that becomes the mount pad behind the pressurized in the protruding circle.
Rubber waterproof cover a is made up of face shield, mount pad, the protruding circle of sealing, and its characteristics are: the top of mount pad is face shield, and the bottom of mount pad is the protruding circle of sealing.
Hexagonal (hexagon)nut b forms on the limit by cap body, mounting groove, closing in limit, after closing up, its characteristics are: the outer upper of hexagonal (hexagon)nut b has mounting groove, the closing in limit that connects with rubber waterproof cover a, after wherein the tarpaulin assembling was finished, the shape on the limit after riveting becomes to close up was answered on the closing in limit.
A kind of tarpaulin and installation method thereof, its characteristics are for to install with the following step:
1, at first with the mount pad of rubber waterproof cover a, the mounting groove that the protruding circle of sealing is put into hexagonal (hexagon)nut b.
2, secondly packing ring c is inserted in rubber waterproof cover a.
3, the packing ring c that next will be with rubber waterproof cover a is placed in the mounting groove of hexagonal (hexagon)nut b, by packing ring c precompression of mount pad to rubber waterproof cover a.
4, the shape on the limit after again the closing in limit riveting of hexagonal (hexagon)nut b being become to close up, make the mount pad of rubber waterproof cover a, the shape of the mount pad of the protruding circle of sealing after in the mounting groove of hexagonal (hexagon)nut b, becoming pressurized, allow mount pad behind the pressurized of rubber waterproof cover a keeping consistently one to around the swollen tension of diffusion, be used to reach the purpose of long term seal.
The utility model is owing to adopted said structure, the technical problem of being deblocked has following beneficial effect compared with prior art: a kind of low cost of manufacture, simple and reasonable for structure, dependable performance, characteristics easy to use are provided, before rubber is also not aging, can work for a long time, be widely used in the tarpaulin of open-air waterproof and dustproof and deepwater work various uses.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of tarpaulin of the utility model, be by rubber waterproof cover a, hexagonal (hexagon)nut b, packing ring c forms, its characteristics are: connecting between rubber waterproof cover a and the hexagonal (hexagon)nut b, be by packing ring c 2 one precompressions of mount pad to rubber waterproof cover a, the mounting groove 5 of the protruding circle of the sealing of rubber waterproof cover a 3 and hexagonal (hexagon)nut b is fitted like a glove and bear certain pressure, shape with the limit 7 after the closing in limit 6 rivetings one-tenth closing in of hexagonal (hexagon)nut b makes the mount pad 2 between rubber waterproof cover a and the hexagonal (hexagon)nut b, seal the shape that becomes the mount pad 8 behind the pressurized in the protruding circle 3.
Rubber waterproof cover a is made up of face shield 1, mount pad 2, the protruding circle 3 of sealing, and its characteristics are: the top of mount pad 2 is face shields 1, and the bottom of mount pad 1 is the protruding circle 3 of sealing.
Hexagonal (hexagon)nut b forms on the limit 7 by cap body 4, mounting groove 5, closing in limit 6, after closing up, its characteristics are: the outer upper of hexagonal (hexagon)nut b has mounting groove 5, the closing in limit 6 that connects with rubber waterproof cover a, after wherein the tarpaulin assembling was finished, the shape on the limit 7 after riveting becomes to close up was answered on closing in limit 6.
A kind of tarpaulin and installation method thereof, its characteristics are for to install with the following step:
