CN2792096Y - Waterproof casing structure for outdoor electronic device - Google Patents

Abstract

The utility model relates to a waterproof case structure of electronic equipment. An annular concave groove is designed on the frame combining the boundary. A ring of rubber strip is embedded in the concave groove. An annular convex strip which is embedded in the concave groove is designed at the upper cover of the equipment. The rubber strip is a silicon rubber strip and the cross section of the silicon rubber strip is circular. The utility model is characterized in that the waterproof property of the electronic equipment is enhanced greatly; the production and the assemblage of the electronic equipment working outside are simple simultaneously; the maintenance and the disassembly for the user are convenient; the waterproof property is excellent; the production cost isn't raised. The matching can make the electronic equipment obtain the request that the electronic equipment can bear the water logging with 1m by the practical proof. The utility model can be disassembled conveniently and quickly again and again. The request for the degree of uniformity of the stress isn't strict when the utility model is assembled.

Description

The waterproof case structure of outdoor electrical equipment

Technical field

The utility model relates to a kind of waterproof case structure of electronic equipment of outside work, especially the shell waterproof construction design of high power station sky accent.

Technical background

The electronic equipment of outside work has more kind, the communication electronic equipment (comprises radio station and meteorological radar etc., also comprise and measuring and satellite communication device), be mounted in outside work as a sky accent equipment overwhelming majority as the radio station of fixed station, because any moisture and the leakage part of dust can cause a day inner high voltage arc and the fault of accent, for this reason, the water-tight performance of electronic equipment just seems especially important.Traditional solution is that cushioning one deck rubber is solved between the loam cake of electronic equipment and lower cover, but facts have proved that this method effect is relatively poor, and assembly crewman's technical ability is had relatively high expectations.If the useful slightly force unbalance of dozens of trip bolt, the sealing property variation will take place and leak in electronic equipment.Therefore, the consistency of the sealing property of electronic equipment in reality is produced the difficult maintenance difficulty of bringing after leaking with control and equipment greatly and maintenance cost also higher.

Summary of the invention

Outdoor electrical equipment waterproof case structure is characterized in that combination interface designs an annular Baltimore groove on the frame, imbeds a circle rubber strip in this Baltimore groove, and in the upper cover design of equipment one annular protrusion bar; Raised item embeds in the annular Baltimore groove.Baltimore groove can be rectangle, trapezoidal, swallow tail shaped slot etc.

Characteristics of the present utility model are: prove through application practice: the water resistance of electronic equipment greatly improves, and simultaneously, the production of the electronic equipment of outside work assembling is simple, and user's repair demolition is convenient, and water resistance is superior, and production cost does not increase.Facts have proved: this cooperation can make electronic equipment reach and bear the requirement that 1m soaks.And can make things convenient for repeatedly fast quick-detach and, when assembling, stressed uniformity coefficient is required not strict.

Description of drawings

Fig. 1 is the utility model structural representation: frame 1, rectangular channel 2, rubber strip 3, annular protrusion bar 4.

Embodiment

A. at the main body frame design one circle rectangular channel of electronic equipment casing, it is compressible to imbed a circle in this rectangular channel, and the cross section is circular silicon rubber bar, also can adopt the rubber strip of other material;

B. in the upper cover design of electronic equipment casing one circle rectangular preiection bar;

C. the present invention guarantees that when electronic equipment casing loam cake and main body were closed up, last rectangular preiection bar was squeezed circular silicon rubber bar with following rectangular channel and compresses 1/3rd (seeing Fig. 1 schematic diagram).

Facts have proved: this cooperation can make electronic equipment reach and bear the requirement that 1m soaks.And can make things convenient for repeatedly fast quick-detach and, when assembling, stressed uniformity coefficient is required not strict.

Claims (4)

1, the waterproof case structure of outdoor electrical equipment is characterized in that combination interface designs an annular Baltimore groove on the frame, imbeds a circle rubber strip in this Baltimore groove, and in the upper cover design of equipment one annular protrusion bar; Raised item embeds in the annular Baltimore groove.

2,, it is characterized in that described rubber strip is that the cross section is circular silicon rubber bar by the waterproof case structure of the described outdoor electrical equipment of claim 1

3, by the waterproof case structure of the described outdoor electrical equipment of claim 1, when it is characterized in that loam cake and main body are closed up, last rectangular preiection bar is squeezed circular silicon rubber bar with following Baltimore groove and is 3: 1 compression.
