Examples

Referring to fig. 1-4, the embodiment provides a mining explosion-proof and intrinsically safe digital display dc power control box, which includes a power control box body 100 and a screen protector 200 installed on the power control box body 100, the power control box body 100 includes a box body 110, a box cover 111 is installed above the box body 110, a handle 112 is installed above the box cover 111 for opening the box cover 111, the screen protector 200 includes a display screen 210, the display screen 210 is located above the box cover 111, mounting plates 220 are symmetrically installed on two sides of the display screen 210, an arch plate 230 is effectively clamped through a symmetrical structure, a chute 221 is installed on the inner side of the mounting plate 220, the cross section of the chute 221 is in an acute triangle structure, the sliding of a guide rod 233 is guided by a bevel edge of the acute triangle, the guide rod 233 is made to stretch during the sliding process by the change of the distance between the bevel edge and the guide rod 233, the arch plate 230 is installed above the display screen 210, the arched plate 230 is used for providing buffering, impact can be effectively relieved when the arched plate 230 faces impact, a plurality of mounting holes are formed in two sides of the arched plate 230, guide rods 233 are connected in the mounting holes of the arched plate 230 in a sliding mode, springs 235 are arranged behind the guide rods 233, and the guide rods 233 are connected in the sliding grooves 221 in a sliding mode.

In this embodiment, in order to improve the smoothness of the sliding of the guide rod 233 in the sliding slot 221, the front end of the guide rod 233 is provided with the universal ball 234, and the universal ball 234 contacts with the inner side of the oblique edge of the sliding slot 221, so that the sliding is changed into rolling, and the smoothness of the movement is improved.

Further, in order to improve the stability of the arched plate 230 during sliding, at least four guide rods 233 are included, a straight plate 222 is disposed behind the sliding groove 221, and the rest guide rods 233 contact the straight plate 222 and move through multi-point support, so as to improve the stability of the movement.

Specifically, in order to improve the cushioning capacity of the arch plate 230, a mounting cylinder 232 is arranged below the arch plate 230, a sliding rod 236 is slidably connected in the mounting cylinder 232, a second spring 237 is arranged above the sliding rod 236, the second spring 237 further absorbs the impact generated when the arch plate 230 is impacted, and the arch plate 230 is helped to reset after the impact is finished.

In addition, in order to reduce the impact of the sliding rod 236 on the screen below, a pad 238 is arranged below the sliding rod 236, the pad 238 is of a hollow structure, the pad 238 is made of rubber, and the pad is of a hollow structure, so that the display screen 210 can be protected to the greatest extent when the pad contacts the display screen 210.
