Embodiment Construction

[0016] Such as Figure 1-4 As shown, the specific embodiment of the present invention is a transmission mechanism of a circuit breaker, including a motor 1 and a motor shaft 11 on it, a lever 2, and a linkage mechanism 3. The motor 1 is formed by the movement of the linkage mechanism 3 and the lever 2. Linkage connection, the shape of the driving rod 2 is T-shaped, a U-shaped clamping edge 23 is formed on one side of the operating end 21, and a sliding groove 22 is formed on the other end of the driving rod 2 opposite to the operating end 21. The setting direction of the sliding groove 22 is the same as The direction of motion of the lever 2 is vertical. Linkage mechanism 3 comprises crank 31, torsion spring 32, slide block 33, and one end of crank 31 forms spring hole 311 relative to motor shaft 11, and the corresponding spring hole 311 side on the upper end surface of crank 31 forms fixing groove 312, and the fixing groove 312 ends The front end is provided with a through h...

Abstract

The invention relates to a transmission mechanism of a circuit breaker, wherein the other end, which is opposite to an operating end, of a lifting lever is provided with a sliding groove; the arranging direction of the sliding groove is vertical to the moving direction of the lifting lever; a link mechanism comprises a crank, a torsion spring and a slide block, and one end of the crank is provided with a spring hole opposite to a motor shaft; the torsion spring is contained in the spring hole and is simultaneously sleeved on the motor shaft; one skintle of the torsion spring is fixedly connected with the crank; the other end of the crank is arranged below the sliding groove of the lifting lever; the upper end of the slide block is arranged in the sliding groove of the lifting lever and isin slide fit with the sliding groove; the lower end of the slide block is fixedly connected with the crank; and the motion of the lifting lever is realized through the sliding of the slide block in the sliding groove under the driven of the positive and negative rotation of the motor. Electromotive switch-on and switch-off are realized through the designed special link mechanism and the designed special lifting lever, the security is improved, the stucking of the lifting lever can not happen, and the reliability of the switch-on and switch-off of the circuit breaker is ensured.

Description

technical field [0001] The invention relates to a transmission mechanism of a circuit breaker. Background technique [0002] Existing molded case circuit breakers use manual closing, which requires manual execution. If there is a fault or internal arc in the molded case circuit breaker, there are certain hidden dangers in manual closing. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a transmission mechanism capable of electrically closing a circuit breaker. [0004] In order to achieve the above object, the present invention adopts a transmission mechanism of a circuit breaker, including a motor and a motor shaft on it, a lever, and a linkage mechanism. The motor forms a linkage connection with the movement of the linkage mechanism and the lever. The other end of the mechanism forms the operating end, and the other end of the lever opposite to the operating end forms a sliding groove. The se...
