[0013] Beneficial effects of the utility model:

[0014] The utility model provides a distribution box cover, which is designed to rotate a rotating rod on a rotating frame, thereby driving the L-shaped clamping shaft to rotate. When the rotating cover is opened, the L-shaped clamping shaft is clamped in a semicircular clamping groove on the surface of the rotating cover to play a supporting role, thereby avoiding the need to hold the cover with one hand and check the inside with the other hand in order to prevent the cover from rotating downward due to gravity after the cover is opened, thereby covering the distribution box again, when the distribution box is placed vertically.

When the rotating cover 3 is opened, the L-shaped card shaft 9 is inserted into the semicircular card groove 4 on the surface of the rotating cover 3 to play a supporting role, thereby avoiding the vertical placement of the distribution box. In order to prevent the cover After opening, it rotates downward due to gravity, so that the distribution box is covered again. It is necessary to hold the cover with one hand and check the inside with the other hand to ensure the normal inspection. Two rotating frames 5 and rotating rods 6 are symmetrically arranged on both sides of the surface of the card plate 1, and each rotating rod 6 is provided with a spherical groove 7, and a rotating ball 8 is slidably connected in the spherical groove 7.
