Problems solved by technology

[0005] The purpose of the present invention is to provide a manual energy storage device for a circuit breaker in view of the technical defects of the above-mentioned existing manual energy storage device, which are inconvenient to use, not strong in humanization, and complicated to assemble. It is changed to the rocker rotating energy storage, which reduces the operating force required for energy storage, reduces the difficulty of assembly at the same time, optimizes the structure of the product, and improves the reliability of the manual energy storage device of the circuit breaker

Embodiment 1

[0025] as attached Figure 1~5 As shown, a manual energy storage device for a circuit breaker is characterized in that it includes a fixed support frame 1, an eccentric rotation mechanism 2 is mounted on the fixed support frame 1, the eccentric rotation structure 2 is connected with a reciprocating connecting rod 4, and the eccentric rotation mechanism The rotation of 2 can drive the reciprocating connecting rod 4 to reciprocate back and forth. The reciprocating connecting rod 4 is connected with a swing lever mechanism group 5, and the swing lever mechanism group 5 is engaged with the ratchet 6. The reciprocating movement of the reciprocating connecting rod 4 can drive the swing lever The mechanism group 5 stirs the ratchet 6 to rotate, and the ratchet 6 is contained on the energy storage mechanism camshaft 7, and the rotation of the ratchet 6 can drive the energy storage mechanism camshaft 7 to rotate to realize energy storage.

[0026] The fixed support frame 1 is installed...

Embodiment 2

[0033] as attached Image 6 As shown, the eccentric rotation mechanism 2 can also be a crankshaft mechanism, the two ends of the crankshaft of the crankshaft mechanism are installed in the two support holes 101, 101' of the fixed support frame 1, and the crankshaft center of the crankshaft is installed at the lower end of the reciprocating connecting rod 4 In the lower oblong hole 401 of the lower oblong hole.

Embodiment 3

[0035] The fixed support frame 1 can also be installed on the circuit breaker body.

[0036] The working principle of the present invention is to shake the handle to input torque to the eccentric rotation mechanism 2, the eccentric rotation mechanism 2 drags the reciprocating link 4 to perform reciprocating motion, and the reciprocating link 4 drags the left swing lever mechanism 501 and the right swing lever mechanism 502 to perform reciprocation Swing the left swing lever mechanism 501 and the right swing lever mechanism 502, the ratchet wheel 6 is driven to rotate through the engagement of the pawls with the ratchet wheel 6, since the left swing lever mechanism 501 and the right swing lever mechanism 502 alternately drag the ratchet wheel 6 to rotate, so no matter Whether the reciprocating link 4 moves downward or upward, the ratchet 6 can drive the camshaft 7 of the energy storage mechanism to rotate and store energy; Move the left swing lever mechanism 501 and the right s...

Abstract

Provided is a manual energy storage apparatus for a breaker. The manual energy storage apparatus comprises a fixed support frame (1), the fixed support frame (1) is equipped with an eccentric rotation mechanism (2), the eccentric rotation composition (2) is connected with a reciprocating connecting rod (4), the rotation of the eccentric rotation mechanism (2) can drive the reciprocating connecting rod (4) to move in a reciprocating manner, the reciprocating connecting rod (4) is connected with a swing lever mechanism set (5), the swing lever mechanism set (5) is engaged with a ratchet (6), the ratchet (6) is arranged on an energy storage mechanism camshaft (7), and the rotation of the ratchet (6) can drive the energy storage mechanism camshaft (7) to rotate so that energy storage is realized. According to the manual energy storage apparatus, conventional unidirectional rotation energy storage is changed, during energy storage via the operation of a handle, energy storage of the mechanism can be realized no matter the handle is shaken in a clockwise manner or in an anticlockwise manner, the efficiency of energy storage operation is higher, the operation is more simple, the operation force is smaller, the apparatus is in more accordance with the comfort during energy storage operation for people, the assembling difficulty is reduced, the product structure is optimized, and the reliability of the manual energy storage apparatus for the breaker is improved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical equipment, and in particular relates to a manual energy storage device for a circuit breaker. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, commonly known as "air switch", also refers to low-voltage circuit breaker. It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse switch and The combination of overheating and unde...
