Device for preventing extension shaft of isolating switch from sinking

Abstract

The invention discloses a device for preventing an extension shaft of an isolating switch from sinking. The device comprises a fixing rod, the two ends of the fixing rod are in threaded connection with a first adjusting rod and a second adjusting rod through threaded grooves correspondingly. The end, away from the fixing rod, of the first adjusting rod is connected with a first movable rod througha bearing. A first portal frame is mounted on the lower surface, close to one side of the first adjusting rod, of the lower surface of the fixing rod; and a first supporting rod is movably arranged on the first portal frame, a first spring is installed at the upper end of the first supporting rod, the upper end of the first spring is connected with the lower surface of the first movable rod, anda second movable rod is connected to the end, away from the fixing rod, of the second adjusting rod through a bearing. The device is simple in structure and reasonable in design, can be effectively fixed in low-voltage switch cabinets with different widths, can be adjusted according to the position of the extension shaft, improves the stability of the extension shaft, and better meets the actual demands.

Description

technical field [0001] The invention relates to the technical field of isolating switch equipment, in particular to a device for preventing the extension shaft of an isolating switch from sinking. Background technique [0002] Low-voltage switchgear is a commonly used power distribution device in the low-voltage electrical industry. It is widely used in residential buildings and industrial and mining enterprises to distribute power. distributed. [0003] Traditional devices have the following disadvantages: [0004] 1. Due to the different specifications of different low-voltage switchgear cabinets, the positions of the isolating switches in different cabinets may be different, resulting in the anti-sinking device not being able to effectively play a supporting role, resulting in poor anti-sinking effect. [0005] 2. At the same time, there is no structure on the inner wall of the cabinet to fix the anti-sinking device. It is usually fixed by bolts, but it is troublesome t...
