The purpose of this utility model is to provide a kind of low-voltage distribution bin door sealing structure, overcomes the deficiencies in the prior art, the degree of protection of distribution box is promoted and is stabilized in the scope of IP55 to IP68.
The utility model is achieved through the following technical solutions: a kind of low-voltage distribution bin door sealing structure, comprise cabinet and door-plate, described door-plate is provided with seal groove towards a side of described cabinet and with the door corresponding section, position, limit of described cabinet, and the bottom even of described seal groove is distributed with fossaperturate; In described seal groove, be equipped with sealing joint strip, the height of described sealing joint strip is higher than the height of described seal groove.
Preferably, in described seal groove, be uniformly distributed and be provided with support along the horizontal plane direction of described door-plate, the arcuate structure that described support is epirelief.
Further preferably, described support offers through hole.
Preferably, described fossaperturate is inverted trapezoidal, and the degree of depth of described fossaperturate is 0.5mm.
Preferably, the material of described sealing joint strip is polyurethane coating expanded material.
Preferably, the upper surface of described sealing joint strip is recessed arcuate structure.
Preferably, the surrounding junction of described seal groove and sealing joint strip is as arc structure.
Compared with prior art, its effect is positive to the utility model.
1, the sealing joint strip of the present utility model structure that is formed in one, has firm degree high, the feature that reliability is strong, avoided employing solid glue to paste after caducous defect.
2, sealing joint strip of the present utility model adopts the good polyurethane coating expanded material of the feature of environmental protection, it has good plasticity, corrosion resistance and resistance to wear, mellow and full attractive in appearance, the non-notch of sealing joint strip the difficult drop-off that form, barriering effect to steam, dust is better, can meet the requirement of shelter of low-tension distribution box.
3, the upper surface of sealing joint strip of the present utility model is recessed arcuate structure, in the time that door-plate closes, air wherein can be extruded, and forms internal negative pressure, and sealing joint strip is firmly adsorbed on cabinet, improves degree of protection.
4, the seal groove that the utility model adopts can carry out horizontal good fixation to sealing joint strip, prevent the horizontal or length travel that sealing joint strip in use produces, guarantee that sealing joint strip coordinates with door the accurate of limit of cabinet, improves the sealing protection grade of low-tension distribution box; On the other hand, the support arranging in seal groove and fossaperturate can make sealing joint strip better be fixed on door-plate.
5, four of seal groove of the present utility model and sealing joint strip interfaces are arc structure, can make stressed more even.
6, the utility model overall structure is easy, easy to use, and protection efficiency is high, the comparatively severe part of environment as places such as high wind heavy rains under, still can make degree of protection reach in the scope of IP55 to IP68; The profile of sealing joint strip is mellow and full attractive in appearance simultaneously, does not come off, and without fracture, can effectively prevent the electric power accident that dust, water enter distribution box and then causes.

Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that.Therefore the utility model is not subject to the restriction of following public embodiment.
Referring to Fig. 1 and Fig. 2, a kind of low-voltage distribution bin door sealing structure, comprise cabinet 1 and door-plate 2, door-plate 2 is provided with seal groove 3 towards a side of cabinet 1 and with door 101 corresponding sections, position, limit of cabinet 1, the bottom even of seal groove 3 is distributed with fossaperturate 4, fossaperturate 4 is inverted trapezoidal, and the degree of depth of fossaperturate 4 is 0.5mm; In seal groove 3, be equipped with sealing joint strip 5, the height of sealing joint strip 5 is higher than the height of seal groove 3, and the material of sealing joint strip 5 is polyurethane coating expanded material.
By spot gluing equipment, the polyurethane coating expanded material after melting is coated in seal groove 3, after polyurethane coating expanded material cooled and solidified, just form sealing joint strip 5, therefore sealing joint strip 5 forms by integrated formed structure with door-plate 2, there is profile mellow and full attractive in appearance, difficult drop-off, do not have breach, thereby can effectively prevent the electric power accident that the impurity such as dust, water enters in distribution box and then causes, its degree of protection can reach in the scope of IP55 to IP68.
Referring to Fig. 3, as the one distortion of embodiment 1, in the seal groove 3 in the present embodiment, be uniformly distributed and be provided with support 6 along the horizontal plane direction of door-plate 2, the arcuate structure that support 6 is epirelief; Support 6 offers through hole.
In the time that the sealing joint strip 5 of liquid condition is coated in seal groove 3, its meeting coated stent 6 also penetrates in the through hole of support 6; After sealing joint strip 5 solidifies, sealing joint strip 5 can more firmly be fixed on door-plate 2 by support 6 and through hole, can not come off easily.
Referring to Fig. 3, as the another kind distortion of embodiment 1, the upper surface of the sealing joint strip 5 in the present embodiment is set to recessed arcuate structure.
In the time that sealing joint strip 5 contacts with the door limit 101 of cabinet 1, be subject to the squeezing action of door-plate 2, the Bas Discharged in arcuate structure, forms negative pressure, thereby sealing joint strip 5 is more firmly adsorbed on a limit 101, plays good protection effect.
