At present, all have a circuit box in the lamp housing of LED street lamp, this circuit box is used for placing electric wire, power lug etc.Because it is outdoor that the LED street lamp need be placed on, therefore, the LED street lamp can suffer the invasion and attack of rainwater unavoidably, and electric wire, power lug be in case the water of contact will cause the short circuit of LED street lamp, causes the LED street lamp can't normal illumination, makes troubles to the pedestrian.This just needs the waterproof sealing structure of a circuit box of design, guarantees the sealing property of circuit box.
By retrieval, find no the waterproof sealing structure that is used in specially on the circuit box, but relevant waterproof sealing structure still has, a kind of hermetically-sealed construction (publication number: CN101222123A) of electrical junction box is disclosed as Chinese patent, comprise: box body, this box body portion within it comprise the part accommodating chamber; The groove that is provided with at the upper surface of the diapire of described box body; Penetrate the bolt hole of the bottom of described groove, the bolt that described box body is fixed on the car body is inserted in the described bolt hole; And flat sealing surfaces, it forms on the upper surface of the diapire of described box body, with opening around described groove, wherein when in the part accommodating chamber that part is contained in described box body, the bottom surface that makes described part and described sealing surfaces closely contact closing described groove, thereby provide sealing between described part accommodating chamber and groove.
The hermetically-sealed construction of the electrical junction box of this patent disclosure, structure be very complicated, processing inconvenience, poor sealing performance, cost are higher, and therefore, this patent can't be applied on the waterproof sealing of circuit box.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the waterproof sealing structure of a kind of simple in structure, good sealing effect, lower-cost circuit box.
The purpose of this utility model can realize by following technical proposal: a kind of waterproof sealing structure of circuit box, comprise it is characterized in that box body with installing port and the cover plate that is fixed on box body installing port place, and be provided with seal between described cover plate and the box body.
The installing port of box body is to be used for making electric wire, power lug etc. can put into box body smoothly, the place is fixed with cover plate at the box body installing port, extraneous water, dust etc. all can't be entered in the box body, and between cover plate and box body, be provided with seal, can guarantee sealing fully between the two.
In the waterproof sealing structure of above-mentioned circuit box, described box body installing port place has the location division of protrusion, and above-mentioned seal is arranged on this location division.By the location division seal can be arranged on the box body more easily.
In the waterproof sealing structure of above-mentioned circuit box, described seal is a rubber seal.
As another situation, in the waterproof sealing structure of above-mentioned circuit box, described seal is the polyurethane sealing ring.
In the waterproof sealing structure of above-mentioned circuit box, described cover plate is fixed on box body installing port place by screw.Be fixed on box body installing port place by what screw made that cover plate can be firm.
In the waterproof sealing structure of above-mentioned circuit box, the quantity of described screw is four.
In the waterproof sealing structure of above-mentioned circuit box, described box body is square, and above-mentioned screw is separately fixed on four angles of box body.
In the waterproof sealing structure of above-mentioned circuit box, described box body adopts plastic material to make.
Compared with prior art, the waterproof sealing structure of this circuit box is guaranteed the sealing fully between cover plate and the box body by increase seal between cover plate and box body, and simple in structure, good sealing effect, cost are lower.
Description of drawings
