DETAILED IMPLEMENTATION METHOD

(5) In order to make the technical solutions and advantages of the patent clearer, the patent will be further described in detail below in conjunction with the accompanied figures.

(6) As shown in FIG. 1, a dust-proof switch cabinet in low-voltage, which comprises a low-voltage switchgear cabinet 1. A plurality of unit drawers 2 are arranged on the low-voltage switchgear cabinet 1, and each unit drawer 2 is provided with a locking push-pull mechanism 3 for locking the unit drawers 2 in the low-voltage switchgear cabinet 1.

(7) As shown in FIG. 2 and FIG. 3, the unit drawers 2 are provided with a drawer stop door 21 located on the outside and a drawer side panel 22 located on both sides. A plurality of elastic tensioning members 5 respectively matched with the corresponding unit drawers 2 are further provided in the low-voltage switchgear cabinet 1, wherein the elastic tensioning members 5 are inserted into the inner cavity of the unit drawers 2 and connected with the low-voltage switchgear cabinet 1, and the movable end of the elastic tensioning members 5 are connected with the drawer stop door 21 of the unit drawers 2, and when the unit drawers 2 are drawn out from the low-voltage switchgear cabinet 1, the elastic potential energy of the elastic tensioning members 5 gradually increases. Therefore, when the unit drawers 2 are drawn out from the low-voltage switchgear cabinet 1, the elastic potential energy of the elastic tensioning members 5 gradually increases as the unit drawers 2 are drawn out, thereby forming a tendency of the unit drawers 2 to move into the low-voltage switch cabinet 1. And after the unit drawers 2 are used, the unit drawers 2 will be reset under the recovery action of the elastic tension members 5, so as to avoid the accumulation of particles and debris in the unit drawers 2 due to the unit drawers 2 being opened for a long-time, and significantly improve the dustproof performance of the low-voltage switchgear cabinet.

(8) It should be noted that the elastic tensioning member 5 is a clockwork. The clockwork uses its elastic force to generate power when it is gradually loosened. According to the principle of lever moment, when the clockwork is fully wound up, the maximum moment is generated due to the longest moment lever is achieved, so the front end of the clockwork needs to be output with small force; after running for a period of time, the clockwork that is tightly wound on the clockwork shaft will slowly loosen, causing the energy of the clockwork to decrease, and when the energy is about to run out, due to the shortest moment lever which makes the moment at its end the smallest, and the output force at this time also becomes smaller; the purpose of stable control of the reset of the unit drawers 2 is achieved.

(9) As shown in FIG. 2 and FIG. 3, the elastic tensioning members 5 are rotatably connected with an adapter fixing piece 23 for connecting with the low-voltage switchgear cabinet 1 at the axis, and the rotation range of the elastic tensioning members 5 relative to the adapter fixing piece 23 is 0°-90°. Thus, the elastic tensioning members 5 are rotatably connected with the adapter fixing piece 23, and the use stability of the elastic tensioning members 5 will be significantly improved, and the service life of the elastic tensioning members 5 will be effectively prolonged. The upper end of the adapter fixing piece 23 is fixedly connected to the low-voltage switchgear cabinet 1, and the lower end of the adapter fixing piece 23 is rotatably connected with an adapter arm 25, and the lower end of the adapter arm 25 is rotatably connected with the elastic tensioning members 5. The elastic tensioning members 5 are first rotatably connected with the adapter arm 25, and then rotatably connected with the adapter fixing piece 23 through the adapter arm 25, achieving the effect of further improving the use stability of the elastic tensioning members 5.

(10) As shown in FIG. 3, the low-voltage switchgear cabinet 1 further includes a magnetic fixing piece 24 which is fixed on the low-voltage switchgear cabinet 1 and a magnetic piece 26 is arranged on the adapter arm 25, an alarm light is arranged on the unit drawers 2. At the same time, the magnetic fixing piece 24 is provided with a matching piece 27 which matches the magnetic piece 26, and the magnetic piece 26 is connected to a switchgear which controls the magnetic attraction of the matching piece 27 with the magnetic piece 26, and when the magnetic piece 26 is magnetically connected with the matching piece 27, the alarm light is turned on. In the present embodiment, the matching piece 27 is an iron block, and the magnetic piece 26 is an electromagnet. Therefore, when the unit drawers 2 are withdrawn from the low-voltage switchgear cabinet 1, the magnetic piece 26 abuts against the matching piece 27 with the rotation of the adapter arm 25. At this time, the magnetic piece 26 and the matching piece 27 are magnetically fixed by the switchgear, which will turn on the alarm light and achieves the purpose of reminding the unit drawers 2 are in the open state.

(11) The above is only preferred embodiment of the present patent, and the protection scope of the present patent is not limited to the above embodiment, but all technical solutions under the idea of the present patent belong to the protection scope of the present patent. It should be pointed out that for those of ordinary skill in the art, several modifications and changes made without departing from the principles of the present patent should also be regarded as the protection scope of the present patent.
