Abstract
The utility model provides a power box cover plate, which comprise a square main body, wherein a vertical fixed edge is arranged around the main body, bolt fixed holes are arranged in the fixed edge, and a plane of the main body outwards extends to form at least two baffle surfaces. The baffle surfaces are arranged on a joint of the power box cover plate and the box body to ensure that a powerful support is formed when the power box cover plate covers on the box body, the contact area of the cover plate and the box body is increased, thus the power box cover plate is more reliable, the power box cover plate is avoided downwards sliding when screws are screwed, and the production efficiency is increased. The power box cover plate has a simple structure; and the manufacture cost of the power box cover plate is not increased.
Description
Technical field
The utility model relates to the covering plate structure of power supply box, and particularly a kind of contact area that increases makes the fixing more reliable power supply box cover plate of cover plate and power supply box casing.
Background technology
Power supply box need cover a cover plate and with bolt itself and casing fixed after its box house mounting electronic at the casing top, in order to protect inner electronic devices and components.To shown in Figure 3, the main body 1 of existing power supply box cover plate is square, and is identical with the cross sectional shape of power supply box casing like Fig. 1, but than cross section (or opening part) undersized of power supply box casing.Be provided with vertical fixed edge 2 around the square main body 1, have bolt hole 3 on the fixed edge 2, after putting into the power supply box casing to the power supply box cover plate, around the bolt of screwing on cover plate and casing are fixed.The fixed form of power supply box cover plate on casing of this structure is just fixing on every side, and defective is that cover plate does not have support component on casing, is in floating empty state, and stationarity is not good, when twisting bolt, is easy to the whereabouts, is difficult for the bolt of screwing on.
The utility model content
Do not have the existing drawback of support component to the existing power supply cover plate, the utility model provides another kind of power supply box cover plate, and it has block face, can on the power supply box casing, form support, makes the power supply box cover plate in fixation procedure, be difficult for gliding.
The technical scheme of the utility model is following:
A kind of power supply box cover plate comprises square main body, is provided with vertical fixed edge around the said main body, has the bolt hole on the said fixed edge, and the plane of said main body stretches out and forms at least two block faces.
Its further technical scheme is: said main body is identical with the cross sectional shape of power supply box casing, and the size of said main body is less than the sectional dimension of power supply box casing.
The useful technique effect of the utility model is:
The utility model is provided with block face in the junction of power supply box cover plate and casing; Form strong support when making the power supply box cover plate on being placed on casing, increase cover plate and casing contact area, thereby make product more reliable; Avoid the downward landing when the turn of the screw of power supply box cover plate, enhance productivity.The utility model is simple in structure, and manufacturing cost can not increase yet.
Description of drawings
Fig. 1 is the front view of existing power supply cover plate.
Fig. 2 is the vertical view of existing power supply cover plate.
Fig. 3 is the right view of existing power supply cover plate.
Fig. 4 is the front view of the utility model.
Fig. 5 is the vertical view of the utility model.
Fig. 6 is the right view of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
To shown in Figure 6, the utility model mainly comprises main body 1, fixed edge 2 and block face 4 like Fig. 4.Wherein main body 1 be square, square main body 1 around be equipped with the fixed edge 2 vertical with main body 1.Select to offer bolt hole 3 on the fixed edge 2.
Referring to Fig. 4, square main body 1 wherein one group of limit 2 (upper and lower) that is relatively fixed is shorter than another group limit 2 (right and left) that is relatively fixed, and reserves space everywhere on both sides, and in this gap everywhere, the plane of main body 1 stretches out and forms four block faces 4.
After main body 1 was covered on the power supply box casing, the upper edge of the bottom of four block faces 4 and power supply box casing fitted tightly, and restriction main body 1 is to bottom offset, but effective support main body 1 makes the power supply box cover plate when the turn of the screw, be unlikely to downward landing.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection range of the utility model.
Claims (2)
