[0015] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0016] Combined with reference Figures 1 to 4 The explosion-proof power distribution cabinet with liftable legs of the present invention comprises a power distribution cabinet 1 and a support base 2 arranged at the bottom of the power distribution cabinet 1, and a support leg 3 is fixedly installed at the bottom of the support base 2.

[0017] A support leg 4 is fixedly installed at the bottom of the power distribution cabinet 1. The support leg 4 is slidably matched with the support base 2. A square groove 6 is provided on the side of the support base 2 away from the support leg 4. A rack 5 is fixedly installed on the side of the support leg 4 corresponding to the square groove 6.

[0018] A shell seat 7 is fixedly installed outside the square groove 6, and shaft holes 8 are opened on the front and rear sides of the square groove 6 and the shell seat 7. A rotating shaft 9 is installed on the shaft hole 8, and a driving gear 10 is installed on the rotating shaft 9. The two driving gears 10 are meshed with each other, and the inner driving gear 10 is meshed with the rack 5 on one side of the support foot 4.

[0019] The rotating shaft 9 on the shell base 7 passes through the shell base 7 and is fixedly installed with a rocker arm 11. A round shaft 12 is fixedly installed on the side of the rocker arm 11 away from the shell base 7. The outside of the round shaft 12 is movably equipped with a hand wheel 13. The hand wheel 13 on the rocker arm 11 can control the internal driving gear 10 of the shell base 7 to engage with the rack 5 for transmission, thereby controlling the distribution cabinet 1 on the top of the support leg 4 to adjust the up and down position.

[0020] Limiting grooves 14 are provided on both the front and rear sides of the support seat 2, and mounting supports 15 are fixedly installed at the positions corresponding to the limiting grooves 14 on the front and rear sides of the supporting foot 4. The mounting support 15 itself has a round rod section that is movably assembled with a limiting pulley 16, and the front and rear sides of the supporting foot 4 are in limited sliding cooperation with the limiting grooves 14 through the limiting pulley 16.

[0021] A connecting rod 17 is fixedly installed at the bottom position of one side of the support base 2 away from the supporting leg 4, and a fixing rope 18 is wound around the outer wall of the circular shaft 12, and the bottom of the fixing rope 18 can be wound and fixed together with the outer wall of the connecting rod 17.

[0022] The bottom of the power distribution cabinet 1 is slidably telescopically matched with the inside of the support base 2 through the support legs 4. In the default state, the support legs 4 are stored inside the support base 2, and the power distribution cabinet 1 is at the lowest height. When the power distribution cabinet 1 needs to be set to an appropriate height, two people standing at diagonally opposite corners of the power distribution cabinet can simultaneously operate the hand wheel 13 to rotate, so as to adjust the upper and lower positions of the power distribution cabinet 1, and finally fix the hand wheel 13. It should be pointed out that the corner position of the hand wheel 13 can be fixed by other means.

[0023] In the present invention, the power distribution cabinet 1 can be manipulated and moved to a set height position to match the on-site environment, thereby improving the practicality of the power distribution cabinet 1 .

[0024] In the present invention, the inner side of the support base 2 is open and can be closed with a cover plate to achieve a closed columnar shape. In the present invention, two diagonally opposite support columns of the four support bases 2 under the power distribution cabinet 1 are provided with such a gear and rack drive mechanism. The other two support columns and the legs only need to be slidably matched.

[0025] Compared with the prior art, the explosion-proof distribution cabinet lifting structure of the present invention is simple and reasonable, has a neat appearance, is mechanically driven, and is safe and reliable.

[0026] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
