[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] See Figures 1-4As shown, a low-voltage withdrawable switchgear includes a cabinet 1 and a mounting groove 2 formed on its surface. A pull-out assembly 3 is embedded inside the mounting groove 2. The pull-out assembly 3 includes a drawer body 4, a guide assembly 5, and a mounting assembly 6 connected sequentially from top to bottom. The guide assembly 5 and the mounting assembly 6 are both located within the mounting groove 2 and are fixedly connected to each other. The guide assembly 5 includes a mounting bracket 7 and a guide rod 8 fixedly connected. A first drive rod 9 and a second drive rod 10 are movably connected sequentially from bottom to top on the inner side of the mounting bracket 7. One end of both the first drive rod 9 and the second drive rod 10 is movably sleeved. The assembly includes a ring seat 11, and the other ends of the first drive rod 9 and the second drive rod 10 are respectively fixedly sleeved with the first drive tooth 12 and the second drive tooth 13. The end of the first drive rod 9 sleeved with the ring seat 11 is also fixedly connected to the connecting arm 14. The outer end of the connecting arm 14 is movably connected to the drive shaft 15. The two ends of the second drive rod 10 are fixedly connected to the auxiliary arms 16. The mounting assembly 6 includes a fixedly connected base plate 17 and support feet 18. The outer side of the base plate 17 is fixedly connected to the support frame 20. The top of the support frame 20 is movably connected to the pneumatic mechanism 19. The top of the pneumatic mechanism 19 is also connected to the drive shaft 15.

[0030] In this embodiment of the utility model, the base plate 17 is a rectangular base plate, which is fixedly connected to the inside of the mounting groove 2 by support feet 18. There are four sets of support feet 18, located at the bottom corners of the base plate 17. The support frame 20 is set as an open rectangular bracket, and its bottom is movably clamped and connected to the bottom of the pneumatic mechanism 19. The base plate 17 achieves the effect of supporting the guide component 5 as a whole in the mounting groove 2. The support feet 18 achieve the effect of facilitating the support and fixation of the mounting component 6 as a whole in the mounting groove 2. The support frame 20 achieves the effect of installing and fixing the pneumatic mechanism 19 while facilitating the subsequent adaptive adjustment of the pneumatic mechanism 19 according to the contraction state. The pneumatic mechanism 19 achieves the effect of pushing the connecting arm 14 to flip and adjust.

[0031] The mounting frame 7 is rectangular in shape, with both ends forming vertical protrusions at bends. The bottom end of the guide rod 8 is fixedly connected to the base plate 17, while the top end is movably connected to the mounting frame 7. The first drive rod 9 and the second drive rod 10 are horizontally positioned vertically, with their outer ends extending outward through the bends of the mounting frame 7. The connecting arm 14 is angled outward, forming an "L" shape with the first drive rod 9. The outer end of the connecting arm 14 is movably clamped to the drive shaft 15 via a connecting seat. The first drive tooth 12 and the second drive tooth 13 are fitted vertically, both located on the outer side of the mounting frame 7. The first drive rod 9 and the first drive tooth 12 control the rotation and adjustment of the second drive rod 10 and the second drive tooth 13. The connecting arm 14 drives the first drive rod 9 to rotate and adjust. The guide rod 8 ensures the overall stability of the guide assembly 5. The second drive rod 10 drives the auxiliary arm 16 to flip and adjust.

[0032] When the pneumatic mechanism 19 is activated, the drive shaft 15 pushes the connecting arm 14 to rotate and adjust. The rotation and adjustment of the connecting arm 14 causes the first drive rod 9 connected to it to rotate. The rotation of the first drive rod 9, under the engagement of the first drive tooth 12 and the second drive tooth 13, then drives the second drive rod 10 to rotate and adjust. The rotation of the second drive rod 10 then drives the auxiliary arm 16 connected to it to rotate and adjust. During this process, the activation of the pneumatic mechanism 19 can also push the guide assembly 5 to move inward and outward, thereby realizing the extension and retraction effect of the drawer body 4 in the mounting groove 2. At the same time, the guide rod 8 can effectively ensure the stability of the movement and adjustment of the guide assembly 5, ensuring that the drawer body 4 is subjected to uniform force and that the drawer can be pulled out smoothly.

[0033] The ring seat 11 is also set to fit the folded end surface of the mounting bracket 7. The auxiliary arm 16 is rectangular and has a magnetic layer at its outer end. The front and rear surfaces of both sides of the inner wall of the mounting groove 2 are provided with magnetic adsorption layers corresponding to the auxiliary arm 16. The outer ends of the auxiliary arm 16 and the second drive rod 10 are set in an "L" shape. The auxiliary arm 16 is used to ensure the stability of the drawer body 4 when it is pulled out, and to prevent the drawer body 4 from shifting or falling out in the mounting groove 2 due to different pulling states.

[0034] When the drawer body 4 is pulled out, the auxiliary arm 16 flips to the sides under the action of the second drive rod 10, and can form an adsorption with the magnetic adsorption layer in the mounting groove 2, thereby ensuring the stability of the drawer body 4 during the pulling operation.

[0035] The inside of the mounting slot 2 is concave on both sides in an arc shape, and its curvature is not less than the maximum curvature of the auxiliary arm 16.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
