Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
As shown in fig. 1 and 2, the switch accessory of the metal junction box of the present embodiment includes a vertical plate 10 and a bottom plate 20.
As shown in fig. 3, the vertical plate 10 includes a first panel 11. The right side of the first panel 11 is bent to one side to form a second panel 12 perpendicular to the first panel 11. A first connecting portion 110 extends outwardly from a lower portion of the first panel 11, and a second connecting portion 120 extends outwardly from a lower portion of the second panel 12.
As shown in fig. 4, a plurality of first through holes 30 are formed in each of the left portion 21 and the right portion 23 of the bottom plate 20, and the first through holes 30 are used as fixing holes for fixing the bottom plate 20 to a wall surface such as a wall by means of fixing members such as screws; the middle portion 22 of the bottom plate 20 is provided with a first strip-shaped hole 220 and a second strip-shaped hole 221 for fixedly connecting with the lower portion of the vertical plate 10.
The first and second connecting portions 110 and 120 are preferably in the shape of a bar, the first connecting portion 110 is bent to one side after passing through the first bar-shaped hole 220, and the second connecting portion 120 is bent to one side after passing through the second bar-shaped hole 221. The first connecting part 110 is bent and clamped below the bottom plate 20, so that the first panel 11 is limited in the vertical direction, and the vertical plate 10 cannot be separated upwards; the bottom edge of the first panel 11 is against the top surface of the bottom plate 20, so that the vertical plate 10 and the bottom plate 20 are vertically limited and fixed. The function and connection manner of the second connection portion 120 are the same as those of the first connection portion 110, and are not described again. Because the first panel 11 and the second panel 12 are mutually perpendicular and integrally connected, and the first connecting portion 110 and the second connecting portion 120 are also mutually perpendicular, the vertical plate 10 and the bottom plate 20 are further fixed in a limiting manner in the horizontal direction, so that the vertical plate 10 cannot swing left and right, front and back relative to the bottom plate. In this way, the lower part of the vertical plate 10 and the middle part of the bottom plate 20 are firmly fixed together by the first and second connecting parts 110 and 120, and the defects that welding consumes time and welding spot stability is not easy to guarantee are overcome.
The bottom edge of the first panel 11 is long, so the number of the first connecting parts 110 arranged at the bottom edge of the first panel 11 can be multiple, so as to enhance the firmness of the connection. In this embodiment, preferably, two first connecting portions 110 extend outwardly from a lower portion of the first panel 11, and correspondingly, two first strip-shaped holes 220 are formed in the bottom plate 20. The connection manner is the same as that of the single first connecting portion 110, and is different only in the number of the first connecting portions 110 and the first strip holes 220.
The utility model discloses a metal junction box switch annex is connected for using other modes such as welding and looks appearance pleasing to the eye, simple structure, and the junction is very firm, and the stability of structure improves by a wide margin, and consequently the life-span of product is also longer. The utility model discloses a manufacturing of metal junction box switch annex can adopt stamping process, realizes automated production more easily.
Further, the left side of the first panel 11 is a bevel edge, and the left side of the first panel 11 is bent to one side to form a third panel 13 perpendicular to the first panel 11. Wherein, the bottom of the third panel 13 also abuts on the top surface of the bottom plate 20, so that the connection between the 10 vertical plates and the bottom plate 20 is firmer.
Further, a second through hole 31 is formed in the middle of the second panel 12, and is used for being fixedly connected with the bridge through a fixing member such as a screw. Wherein, the crane span structure is prior art and does not belong to the utility model discloses a content, and the event is no longer repeated.
The first and second connecting portions 110 and 120 are clamped under the bottom plate 20, so that the two connecting portions 110 and 120 protrude from the bottom surface of the bottom plate 20, which is not beneficial to fixing. Therefore, in the present embodiment, the configuration of the bottom plate 20 is further improved, and the middle portion 22 of the bottom plate 20 is slightly protruded upward compared with the left portion 21 and the right portion 23 thereof, so that the bottom surfaces of the first and second connecting portions 110 and 120 at the bottom of the vertical plate 10 and the bottom surfaces of the left and right portions 21 and 23 of the bottom plate 20 are on the same plane, and the bottom surface of the bottom plate 20 is kept flat and free of protrusions. Thus, the base plate 20 can be attached to a wall surface in a good fit when the base plate is attached to the wall surface.
Preferably, the vertical plate 10 and the bottom plate 20 are made of metal to obtain better mechanical strength.
Further, the surfaces of the vertical plate 10 and the bottom plate 20 are coated with a protective layer (not shown) to improve corrosion resistance and rust resistance. Preferably, the protective layer is zinc.
The above embodiments describe the structure of the metal terminal box switch accessory in detail, but should not be construed as limiting the invention. It will be readily understood that modifications, substitutions and further improvements may be made by those skilled in the art based on the teachings of the present invention, but any modifications or equivalents will fall within the scope of the claims of the present invention.
