[0025] like Figure 1-4 As shown, the utility model is an external protection device for electrical automation equipment, comprising a protection box 1 arranged outside the electrical automation equipment, two box doors 2 being symmetrically provided on the protection box 1, and further comprising:

[0026] The fixing assembly 3 includes two side support plates 31 provided in the protection box 1 and on both sides of the electrical automation equipment, and rubber pads 32 provided in the side support plates 31 and in contact with the electrical automation equipment, and is used to centrally fix the electrical automation equipment placed in the protection box 1 and space it from the side of the protection box 1;

[0027] The power mechanism 4 is provided on the protective box 1 and is used to synchronously open and close the two symmetrical door 2. This design makes it easy to open and close the two symmetrical door 2 slidingly connected on one side of the protective box 1, and the opening and closing angle is large, which is conducive to maintenance operations.

[0028] By pasting side support plates 31 with rubber pads 32 on the fixing components 3 designed in the protective box 1, the two symmetrical side support plates 31 can centrally fix the electrical automation equipment placed in the protective box 1. This not only allows the two end faces of the electrical automation equipment to be installed at intervals from the side of the protective box 1, reducing the chance of direct damage, but also utilizes the insulating properties of the rubber pads 32 to effectively solve the problem of leakage.

[0029] The power mechanism 4 designed on the protective box 1 for synchronously opening and closing the two box doors 2 can open and close the symmetrical box door 2 on the other side while operating the box door 2 on one side. It has a large opening and closing space and is easy to operate, which facilitates the inspection and maintenance of the electrical automation equipment placed in the protective box 1.

[0030] It should be noted that guide rails are installed on the protective box 1 at the bottom corresponding to the two box doors 2 to assist in supporting the box doors 2 to slide left and right.

[0031] In one embodiment, the fixing assembly 3 further includes two scissor telescopic frames 33 symmetrically arranged on the outer end surfaces of the side support splints 31, and the other ends of the scissor telescopic frames 33 are hinged to the inner side wall of the protective box 1. With this design, the two scissor telescopic frames 33 are hinged to the outer end surfaces of the side support splints 31, and the end blocks of the scissor telescopic frames 33 hinged to the support shaft are slidably connected to the end surfaces of the side support splints 31, while the other end blocks of the scissor telescopic frames 33 hinged to the support shaft are hinged to the inner wall of the protective box 1. The folding and unfolding characteristics of the scissor telescopic frames 33 can be used to adjust the distance between the two symmetrical side support splints 31.

[0032] In one embodiment, the power mechanism 4 includes a support cover 41 provided on the protective box 1, a gear 42 provided at the center of the support cover 41, and racks 1 43 and 2 44 meshed with each other at the ends of the gear 42. With this design, by virtue of the support cover 41 welded on the protective box 1 with openings on both sides, the gear 42 rotatably connected at the center of the support cover 41, and racks 1 43 and 2 44 meshed with each other at the ends of the gear 42, when the door 2 on one side is pulled, the gear 42 is rotated by the meshing of the rack connected to that side, thereby driving the meshing rack at the other end of the gear 42 to move linearly, thereby achieving the synchronous opening and closing of the two symmetrical doors 2, with a wide opening and closing viewing angle and convenient operation.

[0033] In one embodiment, one end of the rack 1 43 is fixedly mounted on the top of one door 2, and the end of the rack 2 44, away from the meshing surface, is fixedly mounted on the top of the other door 2. With this design, the rack 1 43 welded to the top of one door 2 and the rack 2 44 welded to the top of the other door 2 allow horizontal movement of one door 2 to be converted into rotational motion, which in turn allows the other symmetrical door 2 to perform linear motion.

[0034] In one embodiment, a linkage mechanism 5 is mounted on the central axis of the gear 42 to drive the two symmetrical side support plates 31 toward or away from each other. This design allows the linkage mechanism 5, which is mounted on the central axis and fixed to the center of the gear 42, to transmit the rotational drive force of the gear 42 to the fixed assembly 3 installed in the protective box 1.

[0035] In one embodiment, the linkage mechanism 5 includes a worm 51 disposed at the end of the central axis of the gear 42, a worm wheel 52 disposed on the worm 51, and a screw 53 disposed on the worm wheel 52, which engages with the tops of the symmetrical side support plates 31. This design allows the worm 51, welded to the central axis of the gear 42, and the worm wheel 52 meshing with the worm 51, to transmit the rotational force exerted on the worm 51 to the worm wheel 52 and the screw 53 fixedly mounted on the worm wheel 52. At this time, the external threads on the screw 53 drive the two symmetrical side support plates 31 to move toward or away from each other.

[0036] It should be noted that the screw rod 53 is a bidirectional screw rod with two symmetrical external threaded parts, which are rotatably connected to the internal threaded grooves that penetrate the end surfaces of the support plates on the symmetrical side support clamps 31 on both sides.

[0037] In one embodiment, two symmetrical side support plates 31 are provided with guide crossbars 6 for limiting linear motion. This design allows the guide crossbars 6, which are connected to the two symmetrical side support plates 31, to guide the side support plates 31 along the guide crossbars 6 when a rotational driving force is applied to the side support plates 31. The guide crossbars 6 limit the position of the side support plates 31, causing the side support plates 31 to move linearly along the guide crossbars 6.

[0038] In one embodiment, the outer end surface of the door 2 on one side is provided with a handle 7. This design provides convenience in operation by fixing the handle 7 with bolts on the outer end of the door 2 on one side, making the operation simple and practical.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
