Summary of the invention
The purpose of this utility model is the chamber door providing a kind of rainwater to be discharged by gap between annular in-flanges and annular sealing strip in time; The purpose of this utility model is also to provide a kind of header box using this chamber door.
In order to solve the problem, in the utility model, the technical scheme of the chamber door of header box is:
The chamber door of header box, comprises chamber door body, chamber door body is provided with the annular in-flanges for being located on respective annular sealing strip periphery, and the bottom of annular in-flanges is provided with at least one leaking hole running through bottom along the vertical direction.
The bottom of annular in-flanges is the straight flange structure of length bearing of trend perpendicular to above-below direction, and leaking hole has multiple, and each leaking hole is arranged along the length bearing of trend interval of bottom.
In the utility model, the technical scheme of header box is:
Header box, comprise front end there is the housing of opening and be placed in the chamber door of opening part, the annular sealing strip being located on mouth periphery is provided with between chamber door and housing, chamber door comprises chamber door body, chamber door body is provided with the annular in-flanges being located on annular sealing strip periphery, the bottom of annular in-flanges is provided with at least one leaking hole running through bottom along the vertical direction.
The bottom of annular in-flanges is the straight flange structure of length bearing of trend perpendicular to above-below direction, and leaking hole has multiple, and each leaking hole is arranged along the length bearing of trend interval of bottom.
Described housing upper end is convexly equipped with the rain-proof eaves above the upper topside for being placed in annular in-flanges.
The transverse slat that described rain-proof eaves comprises single layer structure and the riser be arranged at away from the single layer structure of one end of described housing on transverse slat.
Described housing lower end is provided with the gland head protective cover for being located on corresponding gland head periphery extended along the vertical direction.
Gland head protective cover comprises front side cover plate, rear side cover plate and the left side cover plate be arranged between the cover plate of forward and backward side and right side cover plate, front side cover plate is provided with the cover plate flange turned down backwards.
The beneficial effects of the utility model are: when reality uses, rainwater may enter through the gap between annular in-flanges and housing, then all flow in the gap between bottom and annular sealing strip, bottom in the utility model is provided with leaking hole, the rainwater flow between bottom and annular sealing strip can spill in time through leaking hole and can not lodge in this, even if the situation having annular sealing strip sealing effectiveness to be deteriorated like this occurs, also can not infiltrate in housing through annular sealing strip by rain, ensure that the useful life of electric component in housing.
Further, the upper end of housing is provided with the rain-proof eaves above the upper topside being placed in annular in-flanges, the amount of rainfall entered by gap between annular in-flanges and housing can be reduced like this, decrease the inlet of rainwater between bottom and annular sealing strip, further reduce rainwater and enter possibility in housing through annular sealing strip.
Further, the gland head protective cover that housing lower end is arranged can available protecting gland head, prevents rainwater from entering housing through gland head.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of header box in the utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of Fig. 1 middle shell.
Embodiment
The embodiment of header box is as shown in Fig. 1 ~ 3: comprise front end and have the housing 1 of opening and be arranged at the chamber door 2 of opening part, the annular sealing strip 7 being located on mouth periphery is provided with between chamber door and housing, in the present embodiment, annular sealing strip 7 is fixedly arranged on chamber door 2, chamber door 2 comprises chamber door body, chamber door body is provided with the annular in-flanges being located on annular sealing strip periphery, annular in-flanges comprises upper topside, bottom 11 and be arranged at upper topside, limit, left side between bottom 11, right edge 13, wherein upper topside and bottom are the straight flange structure of bearing of trend perpendicular to above-below direction, bottom is arranged at intervals with along its length multiple leaking hole 10 running through bottom along the vertical direction.Housing is provided with annular ridge 6 in the inner side of annular sealing strip, the upper end of housing is convexly equipped with rain-proof eaves 3, the transverse slat 5 that rain-proof eaves comprises single layer structure and the riser 4 be arranged at away from the single layer structure of one end of housing on transverse slat above the upper topside for being placed in annular in-flanges.The lower shoe of housing offers the installing hole 12 installed for corresponding gland head; housing lower end is provided with the gland head protective cover 9 establishing gland head periphery for ring extended along the vertical direction; gland head protective cover comprises front side cover plate, rear side cover plate and the left side cover plate be arranged between the cover plate of forward and backward side and right side cover plate, front side cover plate is provided with the cover plate flange 8 turned down backwards.
