Technical Field
[0001] The present invention relates to the technical field of isolating switches, and in particular to an operating mechanism for isolating switches. Background Art
[0002] Existing operating mechanisms generally use bevel gears to achieve 90-degree rotational transmission. Although the spring undergoes a process from compression to release during operation, since the transmission is achieved only through the engagement of the gears, the output angular velocity of the mechanism is completely synchronized with the angular velocity of the operator's rotating handle, resulting in a slow opening and closing speed of the switch, which is extremely disadvantageous when interrupting current.

[0029] Furthermore, the diameters of both ends of the second shaft are slightly smaller.
[0030] Furthermore, the spring is a tension spring.
[0031] Here’s how it works:
[0032] When the mechanism switches from closing to opening, the operating handle interface drives the gear to rotate counterclockwise through the interface. The gear engages with the first slider, driving the first slider to translate toward one side of the mechanism. During this translation, the first shaft stretches one end of the spring, while the other end of the spring hangs on the second shaft. When the first slider moves from one side of the mechanism to the center, the side plate is constantly subject to the clockwise torque of the spring, which constrains it to the second boss. When the first slider moves from the center to the other side of the mechanism, the direction of the torque changes because the spring's line of action has passed the side plate's center of rotation. The side plate is immediately rotated clockwise by the spring and then constrained to the other side of the second boss. The mechanism drives the switch's conductive module through the male and female interfaces to quickly complete the opening action.
[0033] When the mechanism switches from opening to closing, the operating handle interface drives the gear to rotate clockwise, meshing with the first slider, thereby driving the first slider to translate toward one side of the mechanism. During this translation, the first shaft stretches one end of the spring, while the other end of the spring hangs on the second shaft. When the first slider moves from one side of the mechanism to the center, the side plate is constantly subject to the clockwise torque of the spring, and the side plate is restrained and immobilized on the second boss. When the first slider moves from the center to the other side of the mechanism, the direction of the torque changes because the spring's line of action has passed the side plate's center of rotation. The side plate is immediately acted upon by the spring to rotate counterclockwise, and then is restrained on the other side of the second boss. The mechanism drives the switch's conductive module through the male and female interfaces to quickly complete the closing action.
[0034] The mechanism uses gears and racks to convert handle rotation into translation of the slider, which then changes the direction of force through translation to achieve instantaneous lateral rotation of the mechanism. This structure completely separates the mechanism's rotational input and output, achieving true energy storage and release.
[0035] Compared with the prior art, the present invention has the following advantages:
[0036] (1) The operating speed of the personnel is independent of the movement speed of the mechanism, which enables the rapid opening and closing of the switch, greatly improving the performance and safety of the switch.
[0037] (2) The rotation angle output by the operating mechanism reaches 90°, which enables the contacts to have a larger opening and closing angle, thereby improving the breaking capacity of the switch by increasing the opening distance.
[0038] (3) The contact modules can be installed on both sides of the operating mechanism, making the assembly more diversified. BRIEF DESCRIPTION OF THE DRAWINGS

[0087] In a specific embodiment, the spring 13 is a tension spring.
[0088] Here’s how it works:
[0089] like Figure 3 、 Figure 5 、 Figure 6 As shown, during the mechanism's transition from closing to opening, the operating handle interface 4 drives the gear 5 counterclockwise through the interface. Gear 5 engages with the first slider 6, driving the first slider 6 in translation toward one side of the mechanism. During this translation, the first shaft 8 stretches one end of the spring 13, while the other end of the spring 13 hangs on the second shaft 10. As the first slider 6 moves from one side of the mechanism to the center, the side plate 9 is constantly subjected to a clockwise torque from the spring 13, retaining it in place on the second boss 1d. As the first slider 6 moves from the center to the other side of the mechanism, the direction of the torque changes because the line of action of the spring 13 passes the side plate 9's center of rotation. The spring 13 immediately rotates the side plate 9 clockwise, and the plate is then retained on the other side of the second boss 1d. The mechanism drives the switch's conductive module through the male and female interfaces 14 and 15, rapidly completing the opening action.
[0090] like Figure 3 、 Figure 5 、 Figure 6As shown, during the mechanism's transition from opening to closing, the operating handle interface 4 drives the gear 5 to rotate clockwise. The gear 5 engages with the first slider 6, driving the first slider 6 to translate toward one side of the mechanism. During this translational motion, the first shaft 8 stretches one end of the spring 13, while the other end of the spring 13 hangs on the second shaft 10. As the first slider 6 moves from one side of the mechanism to the center, the side plate 9 is constantly subject to the clockwise torque of the spring 13, retaining it on the second boss 1d. As the first slider 6 moves from the center to the other side of the mechanism, the direction of the torque changes because the line of action of the spring 13 has passed the side plate 9's center of rotation. The spring 13 immediately causes the side plate 9 to rotate counterclockwise, and the plate is then retained on the other side of the second boss 1d. The mechanism drives the switch's conductive module through the male and female interfaces 14 and 15, rapidly completing the closing action.
[0091] The mechanism uses gears and racks to convert handle rotation into translation of the slider, which then changes the direction of force through translation to achieve instantaneous lateral rotation of the mechanism. This structure completely separates the mechanism's rotational input and output, achieving true energy storage and release.
