Abstract
The utility model belongs to a low-voltage power transmission and distribution equipment, which relates to a low-voltage distribution cabinet mechanical interlocking mechanism applied in low-voltage distribution cabinet. The utility model comprises a rotor axle that is positioned on the cabinet body and can rotate around the axes, a mounting board that is fixed on the cabinet and a movable board that can move relatively to the mounting board. A steel cable composed of a sleeve and steel wire is arranged on the mounting board; one end of the sleeve is fixed on the mounting board; the steel wire passes through the sleeve; one end of the steel wire is propped to the front end of the mounting board along the moving direction of the movable board; a roller is positioned at the rear end of the movable board and leans against the surface of a cam; the cam is positioned on the rotor axle and can rotate along with the latter. Therefore, the utility model has the advantages of simple structure, reliable action, convenient manufacturing and installation and low cost.
Description
Technical field
The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of low-voltage distribution cabinet mechanical interlock mechanism that uses in low-voltage distribution cabinet.
Background technology
In the low-voltage distribution system, for low-voltage distribution cabinets such as drawout cubicles, the electric components such as switch in drawer unit and the cabinet must reliably be interlocked, with the electric component of protection equipment, the generation of minimizing accident.Existing low-voltage distribution cabinet mechanical interlock mechanism generally adopts the transmission of mechanical parts such as linkage, cam mechanism, gear mechanism to realize interlocking.Many, the complex structure of this type of mechanical interlock mechanism transmission link, it is big not only to take up room, and the reliability of interlocking also is difficult for guaranteeing; In addition, the mechanism of traditional structure is higher to the required precision of parts manufacturing and installation, thereby has increased assembly difficulty, has reduced production efficiency, improved production cost.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of simple in structure, reliable in action height, manufacturing and low-voltage distribution cabinet mechanical interlock mechanism easy for installation, that cost is low are provided.
Low-voltage distribution cabinet mechanical interlock mechanism of the present utility model includes one and is installed on the cabinet and the rotating shaft that can rotate around the axle center, also includes a fixed head that is fixed on the cabinet, has a portable plate to relatively move with fixed head; Be installed on the fixed head by a wire hawser of forming by sleeve pipe and steel wire, described sleeve pipe one end is fixed on the fixed head, steel wire is through in the sleeve pipe, one end of steel wire withstands on the portable plate front end along the moving direction of portable plate, and the other end of steel wire and sleeve pipe can be connected on the action component that electric component need be interlocked in the cabinet; The portable plate rear end is equipped with a roller, and this roller is pressed over a cam face, and this cam is installed in the above-mentioned rotating shaft, and can together rotate with rotating shaft.Described portable plate can be connected in the following way with fixed head,, has a chute consistent with the portable plate moving direction on fixed head that is, is fixed with pin simultaneously on portable plate, and this post is locked in the chute that is placed on the fixed head and can be slided along chute.
The utility model mainly adopts wire hawser to transmit the interlocking action of electric component in switch cubicle door or drawer and the cabinet, not only simple in structure, reliable in action, and the restriction of distance between the parts that are not subjected to need to interlock, lower to relative position precision requirement between the parts, make things convenient for manufacturing and installation, improved production efficiency, reduced manufacturing cost.
Description of drawings
Fig. 1 is the utility model embodiment perspective view in one direction;
Fig. 2 is the perspective view of the utility model embodiment on another direction.
Embodiment
Being labeled as among the figure: rotating shaft 1, cam 11, fixed head 2, chute 21, portable plate 3, pin 31, roller 32, wire hawser 4, steel wire 41, sleeve pipe 42.
As shown in the figure, in embodiment of the present utility model, rotating shaft 1 can be rotated on cabinet, fixed head 2 is fixed on the cabinet, and when rotating shaft 1 drove cam 11 rotations, cam promoted portable plates 3 by roller 32 and moves, the moving direction of portable plate 3 is undertaken spacing by pin 31 and chute 21, when portable plate moved, its front end can promote the steel wire 41 in the wire hawser 4, thereby can drive the interlocking elements of the wire hawser other end.
