[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a switch-on module for a power distribution cabinet used in a low-temperature environment, having the following beneficial effects:

[0015] For the switch-on module of the power distribution cabinet used in a low-temperature environment, initially the first elastic member is in a natural elongation state, and the hinged cover is closed with the support frame, ensuring the stability of its closure. When it is necessary to open the hinged cover, the drive frame moves downward until the connecting member is clamped with the support plate. At this time, the first elastic member is in a fixed state, and the hinged cover is opened, facilitating switch-on or other electrical operations. The operation is convenient, avoiding the need for hands to be exposed outside all the time to lift the hinged cover in a low-temperature environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, a switch-on module for a power distribution cabinet used in a low-temperature environment, comprising a protection component and a driving component. The protection component includes a support frame 1 and a hinged cover 2. The hinged cover 2 is arranged on the front surface of the support frame 1, and the upper part of the hinged cover 2 is hinged to the support frame 1. The driving component includes a driving frame 3, a gear 4, a protective cover 5, a first elastic member 6, a support plate 7 and a connecting member. The driving frame 3 is in a U-shape with an open bottom. The left and right sides of the hinged cover 2 penetrate through the support frame 1 and are provided with gears 4. The two side walls of the driving frame 3 are provided with teeth meshing with the gears 4. The left and right sides of the support frame 1 are provided with protective covers 5 covering the gears 4 and the driving frame 3. The bottom wall of the driving frame 3 is connected to the support frame 1 through the first elastic member 6. The front and rear sides of the support frame 1 are provided with support plates 7 fitting with the driving frame 3. The front and rear sides of the driving frame 3 are also provided with connecting members clamped with the support plates 7.

[0023] During actual use, the hinged cover 2 is arranged on the support frame 1. Initially, the first elastic member 6 is in an extended state, and the connecting member does not contact the support plate 7. When the hinged cover 2 needs to be opened, the driving frame 3 is pressed down until the connecting member is clamped with the support plate 7. At this time, the first elastic member 6 cannot reset, and the teeth drive the gear 4 to rotate, and the hinged cover 2 is opened, facilitating the switch-on operation.

[0024] In this embodiment, the connecting member includes a connecting block 8, a clamping block 9 and a second elastic member 10. The connecting block 8 is arranged on the driving frame 3. The front and rear sides of the connecting block 8 are provided with movable grooves. The two ends of the second elastic member 10 are respectively connected to the movable grooves and the clamping block 9. The support plate 7 is provided with a clamping groove, and the clamping block 9 is adapted to the clamping groove. When the movable groove is aligned with the clamping groove, the second elastic member 10 pushes the clamping block 9 to be clamped with the clamping groove. The clamping block 9 is hemispherical, facilitating unlocking. Both the first elastic member 6 and the second elastic member 10 include a spring and a telescopic rod, and the spring is sleeved on the telescopic rod to ensure the stable operation of the whole device.

[0025] To facilitate cleaning impurities, an opening is provided below the protective cover 5, and a handle 11 is arranged on the hinged cover 2 to facilitate opening the hinged cover 2.
