In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model provides a pair of explosion-proof regulator cubicle that can self-extinguishing, including the open rectangle box 1 in top all be equipped with sliding tray 1.1 on the lateral wall of the mutual symmetry of rectangle box 1, sliding tray 1.1 is the dovetail, sliding connection below in sliding tray 1.1 support 3.

The hydraulic cylinder 2 is fixed at the bottom in the rectangular box body 1 through a bolt, the hydraulic cylinder 2 is vertically arranged on a telescopic rod of the hydraulic cylinder 2, and the support 3 can slide up and down in the rectangular box body 1.

The support 3 includes U type frame 3.1, has all seted up on the mutual symmetrical lateral wall of U type frame 3.1 and has rotated hole 3.2, all rotates grafting axis of rotation 3.3 in every rotates hole 3.2, welds the below between two axis of rotation 3.3 regulator cubicle 4, all welds first gear 3.4 at every axis of rotation 3.3's the other end, sets up double-shaft motor 3.5 in the below of U type frame 3.1, welds the motor case in the below of U type frame 3.1 promptly, passes through bolt fastening double-shaft motor 3.5 in the motor case.

Output shafts at two ends of a double-shaft motor 3.5 are welded with second gears 3.6, each second gear 3.6 is in meshing transmission with the corresponding first gear 3.4 through a rack conveyor belt 3.7, protective shells 3.8 are welded on the mutually symmetrical outer side faces of the U-shaped frame 3.1, the protective shells 3.8 are used for isolating and protecting the rack conveyor belts 3.7, guide slide rails 3.9 are welded on the outer side faces of the protective shells 3.8, and each guide slide rail 3.9 can vertically slide in the corresponding slide groove 1.1.
