Embodiment Construction

[0010] The present invention will be described in further detail below according to the drawings and embodiments.

[0011] Such as figure 1 As shown, the interlocking mechanism of the low-voltage drawer-type switch cabinet described in the embodiment of the present invention includes a torsion arm 1, a fan-shaped balance wheel 2 driven by the torsion arm 1, and a rack 4 fixed on the incoming line plug 3. The rotating shaft of the torsion arm 1 is provided with a square drive block 5, the center of the fan-shaped balance wheel 2 is installed on the square drive block 5, and the rim of the fan-shaped balance wheel 2 is provided with gear teeth, and the gear teeth and the rack 4 The limit block 6 is set corresponding to the cut-off position of the torsion arm 1 .

[0012] The limiting block 6 is installed in a groove 8 with a supporting spring 7 so that the torsion arm 1 elastically contacts the limiting block 6 at the cut-off position.

[0013] The interlocking mechanism of th...

Abstract

The invention discloses an interlocking mechanism of a low-pressure drawer type switch cabinet. The interlocking mechanism comprises a torsion arm, a fan-shaped wobble wheel and a gear rack, wherein the fan-shaped wobble wheel is driven by the torsion arm; the gear rack is fixedly arranged on a leading-in plug; a square driving block is arranged on a rotating shaft of the torsion arm; the center of the fan-shaped wobble wheel is mounted on the square driving block; a gear is arranged on a wheel rim of the fan-shaped wobble wheel; the gear is meshed with the gear rack; and a limiting block is arranged at a position corresponding to a stoppage position of the torsion arm. The interlocking mechanism of the low-pressure drawer type switch cabinet, which is provided by the invention, the driving is carried out by adopting a gear rack transmission way; the leading-in plug can stably enter a leading-in plug operating hole; the running stability of the whole interlocking mechanism is guaranteed; moreover, due to the existence of the limiting block, the possibility of misoperation can be further prevented; the fan-shaped wobble wheel is guaranteed not to be disengaged from the gear rack; moreover, the torsion arm is guaranteed to be in elastic contact with the limiting block by means of a supporting spring; and the running safety of the whole mechanism is guaranteed.

Description

technical field [0001] The invention relates to an interlocking mechanism of a low-voltage drawer type switch cabinet. Background technique [0002] Invention Patent No. 200710047592 discloses a misoperation-preventing interlocking device for a low-voltage drawer-type switchgear. In this patent, the main handle 01 of the interlock control drives the hanger pin 2 to perform circular swing, and the swing of the hanger pin 2 pushes the lock pin 3 to move in a straight line, thereby enabling the incoming plug to enter the plug operation hole 5 . [0003] The problem created by this invention is that the swing of the hanger pin 2 drives the lock pin 3 to do linear motion, and its motion itself is not stable enough, and because the force point of the lock pin 3 changes all the time, so the incoming line plug is also moved forward. During the process, due to the existence of torsion force, slight deflection is prone to occur, which makes the contact between the inlet plug and the ...
