Embodiment Construction

[0013] The transmission mechanism in the circuit breaker of the present invention will be further described with reference to the drawings and embodiments.

[0014] A transmission mechanism in a circuit breaker, which includes a transmission shaft 1, and also includes a power rod 2 and an energy storage rod 3. The transmission shaft 1 is provided with two arc-shaped protrusions, which are divided into a first protrusion 4 and a second protrusion. Two bumps 5, the two bumps are arranged at intervals, and the two bumps form an included angle of 90°, the bottom end of the power rod 2 is fixedly connected with the first bump 4, and the energy storage rod 3 is close to the transmission shaft One end of 1 is fixedly connected with the second protrusion 5 with pivot pins. The rotation of the transmission shaft 1 drives the energy storage rod 3 to move horizontally, and the power rod 2 moves up and down to generate upper friction with the sealing ring sleeved on it, so as to prevent t...

Abstract

The invention discloses a transmission mechanism in a circuit breaker. The transmission mechanism comprises a transmission shaft, a power lever and an energy storage rod, wherein the transmission shaft is provided with two arc-shaped bumps and the two arc-shaped bumps are divided into a first bump and a second bump separately; the two bumps are arranged at an interval; the bottom end of the powerlever is fixedly connected with the first bump through a shaft pin; and one end, close to the transmission shaft, of the energy storage rod is fixedly connected with the second bump through the shaftpin. The transmission mechanism has the leak-proof characteristic.

Description

technical field [0001] The present invention relates to an electrical switch, and more particularly to a transmission mechanism in a circuit breaker. Background technique [0002] At present, the large-scale outdoor circuit breaker on the market includes a transmission part, a power rod and an energy storage spring. After the transmission member rotates, the power rod moves horizontally, causing horizontal friction on the sealing ring connected between the power rod and the mechanism box housing, reducing its sealing effect. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a transmission mechanism in a circuit breaker that solves the above problems. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A transmission mechanism in a circuit breaker, which includes a transmission shaft, and also includes a power rod and an energy sto...
