Abstract
The invention discloses a waterproofing door of portable electronic equipment. The waterproofing door is assembled at a waterproof opening of the electronic equipment and comprises a rigid inner core; an elastic outer sleeve matched with the waterproof opening of the electronic equipment in shape wraps the rigid inner core, and the rigid inner core is embedded in the elastic outer sleeve, so that the rigid inner core and the elastic outer sleeve form an inseparable integrity. The invention provides the waterproofing door of the portable electronic equipment, which is reliable and waterproof, and not only has certain elasticity to form high-grade sealing, but also has rigidity to support the waterproofing door and prevent the waterproofing door from deformation.
Description
Technical field
The present invention relates to a kind of electronic equipment enclosure, relate in particular to a kind of water door of portable electric appts.
Background technology
At present; because common portable electric appts does not have safeguard procedures; can't be competent at open-air adverse circumstances; especially in rainy day or wet environment; waterproofing protection can not cause electronic equipment to work preferably; therefore, the water resistance of electronic equipment is the important indicator that the adverse circumstances such as open-air are used.At the military, industry spot and some special occasions, the use of firm portable electric appts is more and more extensive at present, and the water door on electronic equipment is the important guarantee of this series products waterproof reliability, will become its indispensable parts.
Existing water door adopts more whole to be made by rubber or silica gel moulding, and the water door material elasticity of making due to rubber or silica gel material is large and rigidity is not enough, easy affected by environment and deformation failure affects water resistance, and assembling and usability relatively poor.And this type of water door classification of waterproof is not high, with between the anti-mouth of a river directly the plane easily produce the gap with contacting of plane, just can cause and leak once the gap occurs, cause the water door inefficacy.
Summary of the invention
The technical problem to be solved in the present invention is, for the defects of prior art, provides a kind of reliable waterproof, not only had certain elastic force and formed high-grade sealing, but also has the water door that rigidity can support the indeformable portable electric appts of water door.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water door of portable electric appts, be assemblied in electronic equipment and prevent the mouth of a river, comprise rigid inner core, be wrapped with the elastic overcoat that coordinates with electronic equipment waterproof mouth-shaped in rigid inner core, rigid inner core is embedded in elastic overcoat, forms indissociable integral body.
Elastic overcoat edge part is extended the friction tight compression of the waterproof mouth edge of a circle and electronic equipment to its side.
Described compression is along being structure as a whole with elastic overcoat, and the external diameter that compresses the edge is dwindled to its outside gradually by elastic overcoat, makes to compress along the surrounding lateral wall to form the inclined-plane, and compressing along the angle α of lateral wall and elastic overcoat perpendicular bisector is 1～5 °.
Compression is along being provided with at least one circle water proof ring on lateral wall.
Compression is the water proof ring of cambered surface along being provided with two circle cross sections on lateral wall, and the water proof ring cross-sectional area of close elastic overcoat is greater than the water proof ring cross-sectional area in its outside.
Be parallel to each other between adjacent water proof ring.
Rigid inner core is made by the composite material that contains nylon and glass fibre, and elastic overcoat is made by high-tension silica gel.
Elastic overcoat extends one and prevents with electronic equipment the fixed part that the mouth of a river is fixedly connected with.
Fixed part is provided with for the positioning boss that water door is fixed on the fixing hole on electronic equipment and is used for locating.
Rigid inner core is stretched out a rigidity handle to the elastic overcoat extension.
The present invention adopts rigid inner core to make skeleton, rigid inner core is wrapped with and the inseparable integrally-built elastic overcoat of its formation, make water door both have the sealing that elasticity guarantees to prevent with electronic equipment the mouth of a river, having again certain rigidity supports, pliable and tough elastic overcoat both can insert very easily electronic equipment and prevent the mouth of a river, and the skeleton of rigidity supports integral body, make water door can not produce easily distortion, during insertion elastic overcoat is played a driving role simultaneously, guaranteeing to have improved its overall structure fastness on water resistance reliable basis.The hommization and the convenience that use have also been improved.Portable electric appts adopts water door of the present invention, during its operation in the open air, no matter is to be exposed to the rainy day or accidentally to contact wet ground, can reach reliable waterproofing protection, has guaranteed the safe handling of equipment.
Elastic overcoat of the present invention is extended with to a side and compresses the edge, compresses along profile and electronic equipment to prevent that the mouth of a river coordinates, and compressing the edge is integrative-structure with elastic overcoat, has certain thickness, prevent that with electronic equipment mouth of a river contact area is larger, and have high-tension, strengthened the sealing of water door.And compress along on be provided with water proof ring, water proof ring is arranged on the lateral wall that compresses the edge, become a ring-type around compressing along surrounding, and the water proof ring surface is circular arc, with the water door elastic overcoat be that an integral body is made, avoid plane contact between the anti-mouth of a river and water door to be prone to the problem in gap, improved the reliability of waterproof.Water proof ring adopts two circles, and near the water proof ring cross section of the elastic overcoat water proof ring cross section greater than its outside, purpose is the less water proof ring of the cross section anti-mouth of a river of at first will packing into, and cross section is little, easily is loaded into, and has facilitated installation.The water proof ring that cross section is large more is conducive to sealing.Compressing in addition along the surrounding lateral wall is the inclined-plane, and the angle α between the perpendicular bisector of elastic overcoat is between 1～5 °, omit low dip, form pre-small post-large structure, corresponding with the anti-mouth of a river inner small and outside big on portable electric appts, the little water door that is conducive to of front end is installed into the anti-mouth of a river, guaranteed that water door is smooth and easy in the process that enters the anti-mouth of a river, be also simultaneously that inwall for water door and anti-mouth of a river surrounding fits tightly, prevented the intrusion of water, guaranteed the safe handling of portable electric appts.
The elastic overcoat that water door has adopted high-tension silica gel to make, the rigid inner core that the composite material of embedding nylon and glass fibre is made, the composite material of nylon and glass fibre has good intensity and rigidity, support the overall structure of water door, the high-tension silica gel material has good pliability and elasticity, is the main body of water door water-proof function.Adopt the manufacturing technology of post forming to form an integral body both, after water door is filled in the anti-mouth of a river, with the integral body that the shell formation of portable electric appts is sealed, effectively isolated the intrusion of outside current, protected the normal operation of electronic equipment.
