Description
Technical field
This utility model relates to a kind of sealing structure sealing plain washer and possessing IP68 protection.
Background technology
Special industry product or war products are usually required to adapt to the various harsh environment that uses, reliable, durable.As
A part of requirement therein, the most therefore waterproof and dustproof is increasingly subject to paying close attention to of client.
In existing product design, usually use upper and lower covers shell, paid by screw lock, clamp a strip gasket circle
Mode realizes protection, and the shell product made for larger volume, the preferable material of rigidity can also be tackled, but in cannot tackling
The protection of small-size product, usually because the deviation of sealing ring size, the warpage of shell, deformation, causes protection to lose efficacy, and product is criticized
Measure a first-pass yield and be only 56%；Additionally some is because shell is excessive by screw lock pair fastening force, causes shell in time
Passage is ftractureed, and causes product to occur integral protection to lose efficacy within service life.
Utility model content
This utility model is mainly by improving sealing plain washer, and then obtains a kind of barrier propterty better seal
Structure.
The technical solution of the utility model is: a kind of sealing plain washer, including plain washer body 21, at plain washer body 21
Upper and lower surface be respectively provided with groove 22 and protruding 23, the both sides of plain washer body 21 form outer body face 202.
Described groove 22 and projection 23 are the most right.
The protruding side 201 of described protruding 23 both sides tilts, and protruding 23 cross sections are trapezoidal.
Described groove 22 cross section is rectangle, and two outer body faces 202 are parallel.
Of the present utility model a kind of seal structure, including upper cover, lower cover be arranged on sealing plain washer between the two, use
Above-mentioned sealing plain washer, above covers the rib 11 being provided with protrusion, to match with groove 22, under cover and be provided with fitting recess 31,
To match with protruding 23.
The groove side 301 of described fitting recess 31 tilts, and fitting recess 31 cross section is trapezoidal.
Described rib 11 cross section is rectangle.
This utility model passes through sealing plain washer from being changed in shape, is greatly improved sealing plain washer and installs
Reliability.Plain washer lower lobes, for quickly location, can play guidings, consolidate in the matched structural member groove of quick insertion
Fixed effect.Groove on upper surface is applicable to matched rib and extrudes, thus forms the protection together of most critical.
This key protect both sides, be respectively present at two smooth out, can extruded plane (outer body face), if matched
Shell mechanism part extrudes in this place, then can be formed and protect at two.
So, this plain washer can realize three road protection, and can be whole the closeest by the fastening stress differentiation being subject on shell
On envelope plain cushion, greatly reduce the risk of shell mechanism part stress cracking, it is achieved lasting, reliability and durability protection effect.Through testing
Card, this utility model can realize polymer shell 30 meters under water, the long-term diving protection effect of at least 30 days, and sustainable shell
Any machinery cracking, protection was not occurred to lose efficacy in 5 ~ 6 years.
Sealing plain washer of the present utility model can be as universal architecture, it is adaptable to all kinds of sealing requirement product application scenarios.
Improvement based on above-mentioned sealing plain washer, the sealing structure that this utility model provides, upper cover, lower cover and sealing plain cushion
Circle coordinates has a fitting recess on contact plane, for accommodating the projection sealed on plain washer.Under the fastening force effect of appropriateness,
Upper cover, sealing will form stronger contact stress between plain washer, lower cover, and this contact stress can stop external fluid or ash
Dirt enters internal.
Sealing structure of the present utility model, except realizing convenient installation, reliable protection, is additionally also equipped with balancing upper cover, lower cover
Between local fastening force, by local stress break up to bigger contact plane, it is to avoid shell local pressure is excessive, cracking wind
Danger.Being also equipped with absorbing upper cover, lower cover structure warpage, the fit-up gap caused is uneven, visually forms dress unified, attractive in appearance
Join effect.
This utility model is designed by a kind of novel sealing structure, it is achieved install convenient, reliability is high in batches, concordance
Good, and the general purpose I P68 exclusion seal structure extremely low to shell mechanical property requirements.Can be used for outside the structure of all kinds of protection requirements
In shell design (such as water meter).
