Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present embodiment provides a technical solution: an explosion-proof power supply shell comprises a rectangular back plate 1 and an accommodating shell 2 which is of a shell-shaped structure and has a certain inner space, wherein the accommodating shell 2 forms an accommodating space; the back plate 1 is provided with a plurality of mounting and fixing holes, and the accommodating shell 2 is provided with a through hole 21 for a cable to pass through.
In the embodiment, the back plate 1 of the explosion-proof power supply shell is in a round-corner square shape, and the corners are round and melted; the width-to-length ratio of the accommodating shell 2 conforms to the golden section ratio, is the most attractive length-to-width dimension ratio in design, and the dimension of the long edge is the same as that of the backboard 1, so that the long edge of the accommodating shell 2 can be just buckled on the edge of the backboard 1. In addition, in this embodiment, the long side of the accommodating case 2 is transversely fastened to the middle of the back plate 1, so that the upper and lower sides of the back plate 1 are left with vacant back plate 1 areas with the same length. The mounting fixing holes comprise a vertical adjusting hole 11, a horizontal adjusting hole 14, a first near end fixing hole group 12, a second near end fixing hole group 12', a first far end fixing hole group 13 and a second far end fixing hole group 13'. The mounting and fixing holes are arranged on the back plate 1 outside the accommodating space, namely in the area of the vacant back plate 1. The vertical adjustment hole 11 is a guide groove arranged in the vertical direction, and the horizontal adjustment hole 14 is a guide groove arranged in the horizontal direction.
When the anti-explosion power supply shell is used, the anti-explosion power supply shell can be fixed only by matching the vertical adjusting hole 11 and/or the horizontal adjusting hole 14 with the bolt, and the vertical and/or horizontal position can be adjusted by moving the position of the fixing bolt, so that the accurate installation requirement is met. The explosion-proof power supply can be fixed only by the first near-end fixing hole group 12 and/or the second near-end fixing hole group 12' arranged at the upper side and the lower side of the explosion-proof power supply shell. Similarly, the explosion-proof power supply can be fixed only by the first far-end fixing hole group 13 and/or the second far-end fixing hole group 13' arranged at the upper side and the lower side of the explosion-proof power supply shell. Of course, when the explosion-proof power supply is fixed, other combinations may be implemented, such as fixing the first near-end fixing hole group 12 and the second far-end fixing hole group 13', or fixing various possible combinations of the first near-end fixing hole group 12, the second far-end fixing hole group 13', the vertical adjusting hole 11, and the horizontal adjusting hole 14. Therefore, the present embodiment can fix the explosion-proof power supply in various environments such as a plate, a pole, a column, and the like.
The root of the cable extending from the conventional explosion-proof power supply is easily damaged. In this embodiment, offer the through-hole 21 that is used for supplying the cable to pass through on the holding casing 2, like the drawing, set up upside and/or the downside at holding casing 2, because explosion-proof power casing backplate 1 is greater than holding casing 2 width for the length of side, it is regional to form a right angle between 1 regional and the holding casing 2 of backplate of consequently vacant, the cable stretches out through-hole 21, the stretching out point position of cable is in above-mentioned right angle region just, make the stretching out point of cable obtain the regional protection of right angle, in the clashing with of meeting usually, the stretching out point of cable is difficult to meet because of direct collision, thereby can avoid the cable to a certain extent to break from the root.
Furthermore, the shell is made of stainless steel materials, has good corrosion resistance, and can have long service life in high-corrosion environments such as underground environments and the like. Of course, other common materials which are suitable for the use environment of the explosion-proof power supply and can be used for manufacturing the shell are also applicable to the design, such as corrosion-resistant plastics and the like.
Further, the back plate 1 and the accommodating shell 2 are connected by screws or nuts or anchors or by welding. As shown, this embodiment uses a screw connection.
Furthermore, the corners of the accommodating shell 2 far away from the back plate 1 are all or partially chamfered. The chamfer is arranged, so that the effect of beautifying the design can be achieved, and the damage caused by corner collision and the like can be prevented in use.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
