Abstract
The utility model relates to a protective housing for a high-tightness apparatus instrument, which comprises a protective upper cover and a protective lower cover. The lower end of the protective upper cover is provided with a groove, and the upper end is provided with a circle of projection which corresponds with the groove. The groove is internally provided with a sealing ring. The sealing ring is made of silica gel foamed material. The edge of the protective upper cover is provided with first fixing screw holes. The first fixing screw holes are arranged at the outer edge of the groove. The protective lower cover is provided with second fixing screw holes which correspond with the first fixing screw holes of the protective upper cover. The protective lower cover is provided with a wire outlet with a groove structure. The protective upper cover and the protective lower cover are made of plastic. The protective housing has the following advantages: simple structure, high convenience in manufacture, capability of isolating apparatus instrument from outside, and high sealing effect. The sealing ring is made of silica gel formed material. Better sealing effect is obtained when the fixing screws of the upper cover and the lower cover are pressed tighter, thereby controlling sealing performance of the protective housing of the apparatus instrument more easily.
Description
Technical field
The utility model relates to a kind of instrument and meter containment vessel, and particularly a kind of high leakproofness instrument and meter containment vessel belongs to the seal protection field.
Background technology
The containment vessel that instrument and meter is used is as the important device of protection interior instrument instrument, be the important component part of instrument and meter, the quality of containment vessel sealing directly can affect the serviceable life of instrument and meter, therefore, how to improve the sealing of containment vessel, be the problem of at present important consideration; Protecting sheathing commonly used is aluminium material at present; and what adopt is that rubber seal is carried out waterproof, damp proof upsurge vapour; and traditional O-ring seal is not press more tight better; but a field of load is arranged; if the connecting screw hole of upper and lower covers is in O-ring seal; tide vapour enters containment vessel inside by sealing bad screw easily, thereby the instrument and meter of inside is caused damage.
The utility model content
The utility model proposes a kind of high leakproofness instrument and meter containment vessel, having solved can't be to the problem of the long-time protection of instrument and meter in the prior art.
The technical solution of the utility model is achieved in that
A kind of high leakproofness instrument and meter containment vessel; comprise protection loam cake and protection lower cover, described protection loam cake lower end is provided with a circle groove, and described protection lower cover upper end is provided with the circle projection corresponding with described groove; described groove inside is provided with a circle O-ring seal, and described O-ring seal is the silica gel expanded material.
Further, described protection cover rim place is provided with the first fixing threaded hole, and described the first fixing threaded hole is located at the outward flange of described groove, covers under the described protection to be provided with second fixing threaded hole corresponding with protecting loam cake the first fixing threaded hole position.
Further, cover under the described protection and be provided with wire hole, described wire hole is groove structure.
Further, described protection loam cake and protection lower cover are plastic material.
The beneficial effects of the utility model are: the utility model is simple in structure; easy to process; can be with instrument and meter with outside fully isolated; good sealing effect; described O-ring seal adopts the silica gel expanded material; it is tighter that the fixed screw of upper and lower covers is pressed, and then sealing effectiveness is better, thereby is more prone to the sealing of control instrument instrument protection shell.
