Referring to fig. 1-3, according to the embodiment of the switch cabinet with the pressure relief opening, the switch cabinet with the pressure relief opening comprises a cabinet body 11, a plurality of pressure relief openings 12 which are distributed left and right and are penetrated upwards are arranged in the cabinet body 11, a cover plate 13 which is used for covering the pressure relief openings 12 and has the same quantity as the pressure relief openings 12 is hinged to the upper side surface of the cabinet body 11, the cover plate 13 can prevent water and dust from accumulating in the cabinet body 11, an abutting plate 14 is fixedly arranged on the front side surface of the cover plate 13, a plurality of supporting rings 15 are distributed left and right on the cabinet body 11, slide bars 16 are connected in the supporting rings 15 in a sliding mode, triangular plates 18 are connected to the slide bars 16 through mounting frames 17, the triangular plates 18 are arranged in a staggered mode left and right with the abutting plate 14, the side surfaces of the abutting plate 14 are inclined surfaces, the upper side surfaces of the triangular plates 18 are higher than the inner side surfaces of the cabinet body 11, the tail ends of the abutting plates 16 are fixedly arranged on the front side surfaces of the cover plate 13, the left side surfaces of the triangular plates 18 are arranged on the right side surfaces of the supporting plates 16, and can push the handles 19 to move through the left side surfaces of the supporting plates 16, and the right side surfaces of the supporting plates 16 are arranged in a vertical mode, and the supporting plates 19 can be pushed by the handle 19, and can be arranged in the vertical sides of the handle 19, and can be pushed by the handle 19 and can be moved by the handle 16.

In order to avoid the handle 19 being touched by mistake, the rightmost support ring 15 is close to the handle, and a notch 20 for the handle 19 to pass through is arranged in the support rod 15, the notch is in an inclined state, the handle 19 is connected to the slide rod 16 through a rotating ring in a rotating manner, and a worker can pass through the notch when pushing the handle 19 to move leftwards after driving the handle 19 to rotate for a certain angle.

Further, in order to enable the triangle 18 to move to the left limit and then to perform position limitation, there is also an oblique notch 20 in the second support ring 15 from right to left, the distance between the two support rings 15 provided with the notch 20 is smaller than the left-right width of the abutment plate 14, when the slide bar 16 and the triangle 18 move to the left limit, the cover plate 13 is tilted, and at this time, the handle 19 passes through the two notches 20, then the operator causes the handle 19 to naturally drop, at this time, the handle 19 abuts against the left side surface of the second support ring 15 from right to left, at this time, the positions of the slide bar 16 and the triangle 18 are limited, and the angle of the cover plate 13 is limited.

In the second embodiment, in order to enable the angle of each cover 13 to be independently controlled, or to facilitate the operator checking the degree of smoothness of each cover 13 when rotating, the sliding grooves 21 with the same number as the abutting plates 14 are provided in the side surfaces of the sliding rod 16, the bolts 22 inserted into the sliding grooves 21 are provided in the mounting frame 17, the lower end of the mounting frame 17 is provided with a handle 23, and in a normal state, the bolts 22 are abutted to the right side surface of the sliding groove 21, so that the sliding rod 16 can instantly drive the mounting frame 17 to move leftwards when moving leftwards, and when the sliding rod 16 is located at the rightmost side, the operator can independently drive a certain mounting frame 17 to move leftwards through the handle 23, thereby driving a corresponding single cover 13 to rotate.

A positioning pin 24 is slidably connected in the grip 23 up and down, a positioning hole (not shown in the figure) which can be matched with the positioning pin 24 is formed in the lower side surface of the slide rod 16, the positioning pin 24 extends to the lower side of the grip 23, when a worker needs to limit the position of a certain mounting frame 17, the worker can push the positioning pin 24 upwards and insert the positioning pin 24 into the positioning hole after the mounting frame 17 moves to a preset position, and the position of the mounting frame 17 is limited at the moment, namely a triangular plate 18 connected with the mounting frame.

In addition, the improvement made at the pressure relief port 12 in this embodiment is: the edge of the pressure relief opening 12 is provided with a water baffle 25 which extends upwards and is vertically arranged, water accumulated on the upper side of the cabinet 11 is prevented from rushing into the pressure relief opening 12, and the cover plate 13 is internally provided with a cover plate cavity 26 for accommodating and covering the water baffle 25.

To sum up, in the present embodiment, the operator can make the handle 19 swing a certain angle and then make the handle pass through the openings 20 in the two support rings 15, at this time, the slide bar 16 moves leftwards and makes all the cover plates 13 lifted, and then the operator can make the handle 19 abut against the left side surface of the second support ring 15 from right to left, so that the cover plates 13 will not drop.

Alternatively, when it is necessary to detect the rotational smoothness of each cover plate 13, a worker can pull the grip 23 leftwards when the slide bar 16 is at the rightmost side, thereby lifting the corresponding single cover plate 13 and testing the rotational smoothness of the cover plate 13 in the process.

The above embodiments are merely illustrative embodiments of the present utility model, but the technical features of the present utility model are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the present utility model are included in the scope of the present utility model.
