And when being changed to thin plate class formation spare material high duty alloy materials such as almag; Cost of manufacture will increase substantially; And this type portable equipment all has requirements such as wireless, radio frequency, and the sheet metal structure of increase can have a strong impact on the electric properties such as radio frequency of equipment.
Summary of the invention
The technical problem that the present invention will solve is: the electronic product casing that a kind of cover plate and main casing good airproof performance are provided.
In order to solve the problems of the technologies described above, the present invention includes main casing, main casing is provided with opening; The opening of main casing is provided with cover plate outward, is provided with locking mechanism between cover plate and the main casing, and described main casing is provided with the annular seal ring mounting groove around the main casing upper shed; Be provided with the annular resilient seal circle in the sealing ring mounting groove; The sealing ring that cover plate is provided with ring-type compresses convexity, and it is lozenges that sealing ring compresses protruding cross section, and sealing ring compresses protruding prism and is pressed on the sealing ring.
In order to open better sealing function, described cover plate is provided with the described sealing ring of inside and outside two circles and compresses convexity, and sealing ring is clipped in two sealing rings and compresses between the convexity.
Described cover plate is provided with positive stop lug boss, and positive stop lug boss exceeds sealing ring and compresses convexity.When the end face of positive stop lug boss contacts with main casing; Just limited no longer elastic compression of sealing ring, the height of adjustment positive stop lug boss makes decrement and the sealing ring of sealing ring compress the contact pressure that convexity receives and remains on a rational scope of design; Thereby make cover plate keep straight, indeformable.Divide immediately at cover plate in addition, can protect sealing ring to compress protruding tip and not receive foreign object damage.
Spacing for better, described positive stop lug boss is an annular boss, on positive stop lug boss and the main casing outer rim of sealing ring mounting groove or inner edge over against.
It is triangle that said sealing ring compresses protruding cross section.In the equal height condition, cross section is leg-of-mutton protruding littler to the decrement of sealing ring for the sealing ring of other wedge shape compresses than cross section, thereby thrust is little, and the cover plate distortion is little.
For the ease of main casing and cover plate processing, said main casing and cover plate adopt engineering plastics.
For the better elastic distortion can be provided, said sealing ring is the O RunddichtringO.
Beneficial effect of the present invention: the present invention is through locking mechanism locking cover plate and main casing; Make sealing ring compress protruding inclined-plane and compress sealing ring; Sealing ring compresses protruding reaction force to sealing ring and resolves into thrust and the thrust that is parallel to cover plate perpendicular to cover plate; Thrust perpendicular to cover plate is the power that causes cover plate to arch upward and be out of shape; This power compresses protruding reaction force less than sealing ring to sealing ring, thereby reduces the possibility of the distortion of arching upward of cover plate, makes cover plate and main casing good airproof performance.
