Abstract
The utility model relates to a waterproof sealing device for a box body, which comprises the box body, a box cover arranged on the box body, and a sealing ring used for water prevention, wherein, the combination part of the box body and the box cover is provided with a groove; the sealing ring is arranged in the groove; the cross section of the sealing ring forms an O shape, in which case the deformation part of the O-shaped sealing ring is fully contained in the groove; the flanging arranged on the lower end of the box body is provided with a water guide groove. The good sealing effect can be achieved by using small pressure, and meanwhile, the utility model solves the positioning problem of the sealing ring.
Description
Technical field
The utility model relates to the communication machinery apparatus field, specifically refers to a kind of box body waterproof seal that is used on the mobile base station.
Background technique
In mobile communication business, little base station is the major component of covering communication equipment among a small circle, uses very wide.The backboard box body of little base station; it is the protection screen of little base station entodorsum and related device; because it is mainly used in outdoor; its waterproof, sealing, assembling and workability etc. directly influence the life-span and the maintenance of little base station; the particularly sealing of box body, waterproof problem; be to guarantee the box body and the key in internal components life-span, and then also be the key that guarantees little base station life-span and reliability.
At present, outdoor box body waterproof sealing structure mainly is to use the plain seal pad, and as shown in Figure 1, this box body is made up of lid (1), box body (3) and plain seal pad (11), plain seal pad (11) is clipped between the outer of lid (1) and box body (3), and is fixing by screw (12) then.
But this box body waterproof sealing structure has following shortcoming:
1, needs to use bigger pressure that sealing gasket is worked, cause box body distortion itself easily;
2, the sealing gasket installing and locating is inaccurate;
3, sealing surfaces is bigger, has taken the area and the space of box body preciousness;
4, sealing gasket distortion materials flow can not be controlled;
5, the sealing gasket materials are more, and cost is higher.
Technology contents
At said circumstances, the utility model proposes the box body waterproof seal, with solve exist in the prior art because the problem that the required big pressure of sealing gasket sealing is out of shape box body itself.
Solution of the present utility model is as follows:
A kind of box body waterproof seal includes box body, is installed in the lid on the box body and is used for the seal ring of waterproof, has groove on the connecting part of box body and lid, and described seal ring is placed in this groove.
Wherein, the cross section of described seal ring is an O shape, like this, when covering lid, can make the crushed element of O-ring seals be dissolved in described groove fully.
The lower end flange of described box body is provided with water chute.
The utility model has been considered its assembling, maintainability, workability and manufacturing efficiency etc. well, specifically has following advantage:
1, use less pressure that seal ring is worked, box body itself is not easy distortion;
2, the seal ring installing and locating is accurate;
3, can under the surface area condition of limited, realize the box body waterproof;
4, seal ring distortion materials flow can be controlled;
5, the seal ring materials are less, and cost is low;
6, amount of deformation is big, and waterproof is reliable;
7, the structure bottom has anti-ponding structural design, can not produce ponding on part, guarantees waterproofing effect.
Introduce the utility model in detail below in conjunction with description of drawings and specific implementation.
Description of drawings
Fig. 1 is existing box body waterproof sealing structure schematic representation;
Fig. 2 is the utility model embodiment's an installation schematic cross-section;
Fig. 3 is the utility model embodiment's an o-ring groove enlarged diagram;
Fig. 4 is the utility model embodiment's a structural representation;
Fig. 5 is the utility model embodiment's a work schematic representation.
Specific implementation
Be depicted as the utility model embodiment's detailed structure schematic representation as Fig. 2,3,4, the seal ring (2) that it includes box body (3), is installed in the lid (1) on the box body (3) and is used for waterproof, place, connecting part last at box body (3) and lid (1) has groove (5), and described seal ring (2) is placed in this groove (5).Wherein, box body (3) is provided with flange, and its lower end flange has and is used for hydrophobic water chute (4), and the width of water chute (4) is wide as much as possible along the lower end flange; The cross section of seal ring (2) is an O shape, and the part of this O-ring seals (2) distortion can be dissolved in the groove (5) fully.
Installation steps of the present utility model are as follows:
One, on groove (5), is coated with bonding silica gel;
Two, O-ring seals (2) is placed in the groove (5);
Three, lid (1) is pressed;
Four, with screw (12) that lid (1) is fastening.Obviously, this encapsulating method has improved original sealing means greatly, at first, groove (5) makes well location of O-ring seals (2), and the surface area of its seal ring (2) reduces widely, has strengthened sealing effect simultaneously, and impacting force reduces when fastening, has guaranteed that present embodiment is not easy distortion.
Present embodiment is work like this, as shown in Figure 5, when rainwater drenched present embodiment, most rainwater flowed away from its outer surface, have only minimum part from itself and the back mounting plate (6) the slit in infiltrate, the water that infiltrates finally can gather on the flange of box body (3) lower end, owing to have water chute (4) here, and therefore, rainwater has just directly flowed out present embodiment, can not cause ponding, like this, present embodiment has just played good waterproofing effect.
Claims (3)
1, a kind of box body waterproof seal, the seal ring that it includes box body, is installed in the lid on the box body and is used for waterproof is characterized in that, has groove on the connecting part of box body and lid, described seal ring is placed in this groove.
2, a kind of box body waterproof seal as claimed in claim 1 is characterized in that described box body is provided with flange, also has on the flange of its lower end to be used for hydrophobic water chute.
3, a kind of box body waterproof seal as claimed in claim 1 is characterized in that, the cross section of described seal ring is an O shape.
