Abstract

A cabinet for mobile base station comprises a box, a box cover arranged on the box and a sealing cushion loop for water-proof, wherein, a sealing slot is arranged at combination position between the box cover and the box. The sealing cushion loop is arranged inside the sealing slot. A first protruding edge and a water-proof protruding edge for guiding water are arranged on outer circumference of the box cover, wherein, the first protruding edge is used to package the water-proof protruding edge from outside. The box cover body is thin plate shape. A second protruding edge is arranged on inner side of the first protruding edge on the box cover. The sealing slot is formed between the second protruding edge and the first protruding edge. The utility model makes use of smaller flange to realize water-proof, thereby enlarging effective utilization space. The sealing cushion loop can not directly contact the rainwater, thereby prolonging the aging process and the life span. The manufactured box and box cover have a small planar degree with good water-proof effect and reduction of manufacture cost.

Description

The mobile base station cabinet

Technical field

The utility model relates to the mechanical field of communication equipment, specifically refers to a kind of outdoor mobile base station cabinet with water-proof function that is used for.

Background technology

Now, along with the continuous development of mobile communications industry and universal day by day, also increase with mobile base station out of doors thereupon.For this kind equipment, except the performance that guarantees its system itself, also should possess water-proof function,, just become the industry utmost point to want a problem that solves with cabinet so how to design a kind of mobile base station with water-proof function to prevent to influence the normal operation of base station because of entering of rainwater.

For addressing the above problem, the industry outdoor crate with water-proof function commonly used at present mainly contains following two kinds: a kind of is the cabinet with flat seal packing ring, as shown in Figure 1, this cabinet is made of flange 13 and the flat seal packing ring 11 on case lid 1, casing 3, case lid 1 casing 3, flat seal packing ring 11 is clipped in 13 of the flanges of case lid 1 and casing 3, fixing with screw 12 then.Another kind is the cabinet with O shape seal washer, as shown in Figure 2, this cabinet is made of flange 13 and the O shape seal washer 14 on case lid 1, casing 3, case lid 1 casing 3, also be provided with the seal groove 2 of laying O shape seal washer 14 on the flange 13 of casing 3, after O shape seal washer 14 is inserted seal groove 2, fix at flange 13 places of case lid 1 and casing 3 with screw 12.

Though above-mentioned two kinds of cabinet hermetically-sealed constructions all have certain water-proof function, because the defective on the structural design own, so there is following shortcoming respectively in the two:

Cabinet with flat seal packing ring:

Need bigger pressure just can make the sealing gasket compression when 1, the flat seal packing ring seals, cause cabinet distortion itself, thereby cause the waterproof effect variation;

2, flat seal need be on sealing gasket the processing bolt hole, and the quantity in hole is more, the processing cost height;

3, the cabinet upper and lower covers needs bigger flange face that seal washer is installed, and causes the cabinet volume to become big, effectively utilizes volume to reduce;

4, flat seal packing ring materials are more, and material cost is higher;

5, seal washer directly is subjected to the rainwater effect, easy ageing failure, and useful life is short.

Cabinet with O shape seal washer:

1, seal washer directly is subjected to the rainwater effect, easy ageing failure, and useful life is short;

2, cabinet processing difficulties, mismachining tolerance is big, the cost height.

Technology contents

The utility model provides a kind of mobile base station cabinet, to solve the problem of seal washer because of being subjected to rain drop erosion and solar radiation to wear out easily, lost efficacy in the prior art.

Solution of the present utility model is as follows:

A kind of mobile base station cabinet, include casing, be installed in the case lid on the casing and be used for the seal washer of waterproof, junction at case lid and casing has seal groove, described seal washer is placed in the sealing groove, outer rim at case lid is provided with first bead, outer rim at casing also is provided with the waterproof bead that is used for water guide, and this first bead envelopes this waterproof bead from the outside.

Wherein, described case lid main body is lamellar;

Also be provided with second bead that is positioned at the described first bead inboard on the described case lid, form described seal groove between this second bead and first bead;

Described first bead is arranged on other three edges except that lower limb of described case lid continuously;

Described waterproof bead be arranged on continuously described casing around.

The utility model has been considered its maintainability, machinability and production efficiency etc. well,

Specifically have following advantage:

1, to account for the volume of cabinet little for waterproof construction, can utilize less flange to realize waterproof, and effective usage space of cabinet is big;

2, the cabinet periphery has designed unique waterproof, water guide structure, and the cabinet waterproof is more reliable;

3, but the cabinet mold is produced in batches, has good processability, and processing cost is low;

4, the design of cabinet bottom has anti-ponding structure, can not produce ponding on cabinet;

5, seal washer can directly not be subjected to the effect of rainwater, can delay its ageing process, has prolonged useful life;

6, the flatness of processing rear box, case lid is little, and waterproof sealing is effective.

Introduce the utility model in detail below in conjunction with description of drawings and specific implementation.
