Embodiment 2:

Referring to FIG. 3 , the only difference between this embodiment and the first embodiment is that the description of the manual closing and opening assembly 72 is added in this embodiment, and in practical applications, most of the spring-operated devices also have the manual closing and opening assembly 72 , the first embodiment is only omitted for the convenience of the detailed description of the structure of the circuit breaker preventing reclosing interlock mechanism. specific:

Referring to FIG. 3 , the above-mentioned closing release 71 and the above-mentioned manual closing and opening assembly 72 are respectively disposed on both sides of the above-mentioned closing lever 731 . The manual closing and opening assembly 72 is disposed adjacent to the rear end of the above-mentioned limit turning plate 5 . The manual closing and opening assembly 72 includes a manual handle 721 , a manual crank arm 722 and a closing push rod 723 . The manual handle 721 and the manual crank arm 722 are coaxially assembled and rotated synchronously. The closing push rod 723 is arranged on the manual crank arm 722 Adjacent to the position of the limit turning plate 5, the manual handle 721 is used to drive the closing push rod 723 to move by driving the manual crank arm 722 to rotate, and the closing push rod 723 pushes the limit turning plate by moving the closing push rod 723 itself. 5 to drive the closing half shaft 73 to rotate. The closing push rod 723 is adjacent to the side of the limit turn plate 5 and drives the closing half shaft 73 to rotate by pushing the side of the limit turn plate 5 . The side of the limit turn plate 5 pushed by the closing push rod 723 is the limit turn plate 5 The side of the side facing away from the side on which the surface structure smoothly transitions.

Continuing to refer to FIG. 3 , the difference between the specific structure of the above-mentioned manual closing and opening assembly 72 and the manual closing and opening assembly 72 commonly used in the art in the prior art is only that the closing half shaft 73 in the prior art cooperates with the The push plate is pushed and driven by the closing push rod 723, and in this embodiment, the closing push rod 723 directly pushes the limit turning plate 5 to realize the realization of simplifying the structure of the push plate. Since the strength of the user when turning the manual handle 721 is uncertain, the present invention uses the structure in which the closing push rod 723 directly acts on the limit turn plate 5, so that the user can rotate the manual handle with a relatively large force when reclosing occurs. 721, when the force is transmitted to the limit turn plate 5, it is directly absorbed by the limit top plate 3 pressed against its limit portion 51, thereby preventing the internal damage of the spring operating device from being directly damaged when the user recloses the brake with a large force. structure or prevent the failure of reclosing, etc. Even if the user rotates the manual handle 721 with such force that the mechanical structure linked with the manual handle 721 may be damaged, the above-mentioned structure of the present invention can fix the limiting rotary plate 5 due to the limiting top plate 3 pressing the limiting portion 51 against the limiting portion 51 . The force can stop the damage of the mechanical structure to the manual closing and opening components 72, etc., so as to reduce the above losses to a minimum.

Referring to Figure 1, Figure 2, Figure 3, during the use of a circuit breaker preventing reclosing interlock mechanism of the present invention, when the spring operating device is in the closed state, the above-mentioned limit top plate 3 and the above-mentioned limit turn plate 5 are used.

When the spring operating device is controlled to open in the closed state, the rotation of the output arm 74 drives the interlock arm 1 to rotate synchronously, and the rotation of the interlock arm 1 will lift the end of the limit top plate 3 through the interlock plate 2 Then, the limiting top plate 3 is rotated about the top plate mounting shaft 4 as the axis, and the tail end of the limiting top plate 3 is separated from the limiting portion 51, that is, the limiting top plate 3 no longer restricts the closing of the spring operating device. After the spring operating device is closed in the above-mentioned open state, if the reset lag of the closing half shaft 73 relative to the reset of the output arm 74 occurs, the rear end face of the limiting top plate 3 is adjacent to the above-mentioned smooth transition curved surface structure. The pin 11 can move along the guide groove 21, and the structure will not hinder the movement of the interlock arm 1, so that the circuit breaker prevents the reclosing interlock mechanism and even the spring operating device from being damaged. The aforementioned guide pin 11 moves along the guide groove 21 to compress the interlocking return torsion spring 6 . Although the rear end of the limit top plate 3 is adjacent to the smoothly transitioned curved surface structure, due to the arrangement of the smooth transitioned curved surface structure, the adjoining relationship will not hinder the reset of the limit turning plate 5 (that is, will not hinder the closing half shaft 73 ). reset), and then when the limit turning plate 5 is reset, driven by the interlock reset torsion spring 6, the tail end of the limit top plate 3 will fall into the limit part 51, and the above-mentioned reclosing prevention function is restored.

The above are only specific embodiments of the present invention, but the design concept of the present invention is not limited to this, and any non-substantial modification of the present invention by using this concept should be regarded as an act of infringing the protection scope of the present invention.
