Abstract

The utility model discloses a resetting lever of a resetting device. The resetting lever consists of a lever strip (1) and a lever point axis (3), wherein a pivot mounting slot (2) is formed in the lever strip (1). The resetting lever is designed in the resetting device; the resetting device is arranged in a reversing mechanism; the reversing mechanism is arranged in a main command controller, so that a function of flexibly reversing the main command controller is realized, and the main command controller is small in size and easy to operate during application; a transmission part is simple; a contact is easy to switch on and switch off; the system is high in control precision; the working performance is stable and is durable; and moreover, the resetting lever can adjust gear positions according to a requirement and is suitable for different types of sets of hoisting machinery.

Description

The restoring lever of resetting means

Technical field:

The utility model relates to a kind of restoring lever of resetting means.

Background technique:

Master controller is widely used in the crane tool electric control system, belongs to the electric control system core; The master controller that former domestic industry is used exists that volume is large, steering force is large, drive part is loaded down with trivial details, and the contact break-make is not clear-cut, and system's control accuracy is low, working life is short, the defectives such as service behaviour is unstable, and because gear limits, can't be applicable to the Hoisting Machinery of different model; And the structure of each parts in the master controller is extremely important.

Summary of the invention:

The purpose of this utility model provides a kind of restoring lever of resetting means;

The utility model is to adopt following technological scheme to realize its goal of the invention: a kind of restoring lever of resetting means, and it is formed, and is provided with fulcrum mounting groove 2 at lever bar 1 by lever bar 1, lever force axle 3; Lever force axle 3 is installed on the lever bar 1.

Owing to adopted above technology the utility model to realize preferably its goal of the invention, the design of this restoring lever is in resetting means, the resetting means design is in changement, changement is installed in the master controller, realized the flexibly function of commutation of master controller, so that master controller volume in application is little, operating handle is light, drive part is simple, the contact break-make is clear-cut, system's control accuracy height, stable work in work, durable in use, and can adjust as required gear, be applicable to the Hoisting Machinery of multiple different model.
