Abstract
The utility model belongs to the technical field of the fan technique and specifically relates to a waterproof conjunction box for blower fan, is equipped with junction box body, seals backing plate, junction box cover mounting flange and junction box cover, its characterized in that be equipped with bolt insertion hole and closed hole on the sealed backing plate from top to bottom in proper order, the closed hole is greater than bolt insertion hole, the up end of the flange of riveting nut tip and lateral surface respectively with the grafting that cooperatees of the sealed closed hole that fills up, the terminal surface matches to seal up with junction box cover mounting flange and pegs graft under the flange of riveting nut to make the periphery formation step of the flange of riveting nut sealed, satisfied the operation requirement under the open -air sleet climatic conditions, improved the waterproof sealing effect greatly.
Description
Technical field
The utility model relates to blower fan technical field, specifically a kind of blower fan waterproof junction box.
Background technology
At present, blower fan terminal box is electrical connection position, therefore sealing requirements is stricter, blower fan terminal box is by junction box body, sealed bolster plate and connector cover and junction block composition, blower fan junction box body is provided with connector cover mounting flange, with riveting nut on connector cover mounting flange, blower fan junction box body and connector cover make to be bolted together, and be provided with sealing gasket therebetween, in use, because riveting nut cephalic par periphery is provided with flange, in order to be connected with connector cover mounting flange, the diameter of usual connector cover Method for Installation flange aperture is more than or equal to the diameter of flange, could the flange of riveting nut cephalic par be inserted in the connecting hole of connector cover mounting flange and sealed bolster plate, the deficiency of this structure is: form gap between the periphery of riveting nut head and connector cover mounting flange, cause poorly sealed, easy water inlet, and form potential safety hazard.
Summary of the invention
The purpose of this utility model be solve above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, sealing property is high, the blower fan waterproof junction box of long service life.
The utility model solves the technical scheme that its technical problem adopts:
A kind of blower fan waterproof junction box, be provided with junction box body, sealed bolster plate, connector cover mounting flange and connector cover, it is characterized in that described sealed bolster plate is provided with screw jack and closed hole from top to bottom successively, described closed hole is greater than screw jack, the upper surface of the flange of described riveting nut end and lateral surface match with the closed hole of sealed bolster plate grafting respectively, match with connector cover mounting flange sealing grafting for the flange lower surface of described riveting nut, to make the periphery forming station step seal of the flange of riveting nut, meet the instructions for use under outdoor sleet weather conditions, substantially increase waterproof sealing effect.
The utility model, owing to adopting said structure, has the advantages such as rational in infrastructure, sealing property is high, long service life.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present utility model.
Reference numeral: sealed bolster plate 1, connector cover mounting flange 2, connector cover 3, bolt 4, riveting nut 5, screw jack 6, closed hole 7, flange 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of blower fan waterproof junction box, be provided with junction box body, sealed bolster plate 1, connector cover mounting flange 2, connector cover 3, bolt 4 and riveting nut 5, described junction box body, sealed bolster plate 1, the annexation of connector cover mounting flange 2 and connector cover 3 is same as the prior art, this does not repeat, it is characterized in that described sealed bolster plate 1 is provided with screw jack 6 and closed hole 7 from top to bottom successively, described closed hole 7 is greater than screw jack 6, the upper surface of the flange 8 of described riveting nut 5 end and lateral surface match with the closed hole 7 of sealed bolster plate 1 grafting respectively, match with connector cover mounting flange 2 sealing grafting for flange 8 lower surface of described riveting nut 5, to make the periphery forming station step seal of the flange 8 of riveting nut 5, meet the instructions for use under outdoor sleet weather conditions, substantially increase waterproof sealing effect.
The utility model when mounted, be tightly connected in junction box body upper end and connector cover mounting flange 2, connector cover mounting flange 2 is provided with riveting nut installing hole again, described riveting nut installing hole is fixedly connected with riveting nut 5, described connector cover 3 fits through sealed bolster plate 1 and connector cover mounting flange, the flange 8 of described riveting nut 5 is inserted in the closed hole of sealed bolster plate 1, the through hole that described bolt 4 establishes 3 to have through connector cover, the screw jack that sealed bolster plate 1 is provided with is fixedly connected with riveting nut 5 screw thread, thus sealed bolster plate 1 and connector cover mounting flange 2 can be fit together closely, improve sealing, after installation, because the hardness of sealing gasket material itself is moderate, ageing-resistant, wear-resistant performance, make the sealing property of blower fan, abrasionproof effectively improves.
The utility model, owing to adopting said structure, has the advantages such as rational in infrastructure, sealing property is high, long service life.
