Telescopic rotary unlocking device of power distribution cabinet

Abstract

The invention relates to a telescopic rotary unlocking device of a power distribution cabinet, which is designed for solving the technical problems of poor cam structure stability and reset effect, inconvenience in production and assembly and poor universality of the existing similar products. The unlocking device comprises a transmission mechanism and an unlocking mechanism. The unlocking device is characterized in that a cam of the transmission mechanism is fixed in a fixing seat; a cylindrical section of a rotating shaft is sleeved with a sleeve of a shifting piece; meanwhile, a spring is arranged on the outer diameter of the cylindrical section of the rotating shaft in the sleeve; a protruding sickle head is arranged on one side of the outer diameter of a rotating disc of the shifting piece; a tilted introducing port is formed in one side of the end portion of the sickle head; one end of a connecting piece of the unlocking mechanism is fixed in a square groove in one side of a fixing seat; a spring bolt is arranged on one side of an opening of a lock nozzle in the square groove; a hook hole is formed in the spring bolt at the lock nozzle; a hook is arranged on the fixing seat above the hook hole; the hook is bent in an L shape; the bent position of the hook is fixed to the fixing seat through a clamp spring on a third small cylinder to swing; a hook head at one end of the hook is inserted into the hook hole of the spring bolt; and the hook head of the hook is inserted into the hook hole of the spring bolt.

Description

technical field [0001] The invention relates to an unlocking device matched with a circuit breaker in a power distribution cabinet, and is a telescopic and rotating unlocking device for a power distribution cabinet. Background technique [0002] At present, the main status of the power distribution cabinets on the market is to open the cabinet door with a key, and then operate the circuit breaker. It is time-consuming and laborious to operate step by step. At the same time, it is operated inside the power distribution cabinet, which is not safe; in a few cases, the external handle is inserted into the lock. device, and the lock device is connected to the breaker of the power distribution cabinet. When the external handle rotates 90 degrees, the mechanism inside the lock device drives the circuit breaker to rotate 90 degrees, so as to realize the opening and closing of the circuit breaker, and realize the process of closing and opening the door lock synchronously. But most o...
