[0030] Here’s how it works:

[0031] In the utility model, the operating mechanism comprises an active module and a driven module.

[0032] The first bracket, the first spring, the first gear, the second gear, the first shaft and the second shaft constitute the active module; the third shaft, the splint, the retaining ring, the bushing, the amplifying rod, the slider, the slide bar, the rocker bar, the gasket, the second spring, the fourth shaft, the sixth shaft, the fifth shaft, the crank, the synchronizing rod and the seventh shaft constitute the driven module.

[0033] When the switch starts to close, the first gear rotates clockwise, and the first side plate also starts to move clockwise. When the first side plate rotates to a certain angle around the second hole, one end of the tenth slot on the first side plate contacts the slide bar and pushes the slide bar to move around the third axis, and the slide bar drives the clamping plate to move clockwise around the third axis. At the same time, the slide bar moves downward along the sixteenth slot, driving the swing arm to move counterclockwise around the seventh axis. In this process, the slide bar and the clamping plate push the gasket downward to compress the second spring.

[0034] In addition, the slide bar moves in the nineteenth slot, driving the amplifying rod to move clockwise around the sixth axis. The amplifying rod, the crank and the synchronous rod form a connecting rod mechanism. The height of the rotation center of the amplifying rod is lower than the height of the rotation center of the clamping plate, so it can play a role in amplifying the rotation angle of the clamping plate. The rotation angle of the clamping plate is 90°, and the rotation angle of the amplifying rod is 180°. The fourth axis can slide in the fourteenth slot of the slide bar.

[0035] Before the driven module passes the dead point, the slider will not move because the fourth axis moves in the fourteenth slot. When the two-link module composed of the splint and the rocker arm passes the dead point (the splint and the rocker arm are on the same straight line), the second spring is released, the slide bar is out of contact with the first side plate, the second spring drives the driven module to move, the fourth axis contacts the slider, and the movement of the amplifying rod can be transmitted to the slider in a 1:1 ratio, thereby driving the slider to rotate clockwise. When the twenty-first boss contacts the fifth boss, the driven module reaches the closing position and the movement stops. The active module is driven by the first spring. When it rotates to the eleventh slot and contacts the seventh boss, the active module reaches the closing position and the movement stops.

[0036] When the gate starts opening, the first gear rotates counterclockwise, and the first side plate also starts to move counterclockwise. When the first side plate rotates to a certain angle around the second hole, one end of the tenth slot on the first side plate contacts the slide bar and pushes the slide bar to move around the third axis, and the slide bar drives the clamping plate to move counterclockwise around the third axis. At the same time, the slide bar moves downward along the sixteenth slot, driving the swing rod to move clockwise around the seventh axis. In this process, the slide bar and the clamping plate push the gasket downward to compress the second spring.

[0037] In addition, the slide bar moves in the nineteenth slot, driving the amplifying rod to move counterclockwise around the sixth axis. When the two-link module composed of the splint and the rocker bar passes the dead point (the splint and the rocker bar are located on the same straight line), the second spring is released, the slide bar is out of contact with the first side plate, the second spring drives the driven module to move, the fourth axis contacts the slider, and the movement of the amplifying rod can be transmitted to the slider, thereby driving the slider to rotate counterclockwise. When the twenty-first boss contacts the fifth boss, the driven module reaches the closing position and the movement stops. The active module is driven by the first spring, and when it rotates to the eleventh slot and contacts the seventh boss, the active module reaches the closing position and the movement stops.

[0038] The second bracket is clamped by the sixth boss, the outer wall of the first slot, and the inner walls of the first shell and the second shell. The screw can be inserted through the contact module and cooperate with the seventeenth hole to install the contact module. The twentieth slot and the eighteenth slot can both be equipped with handles, so that the top and side of the operating module can be opened and closed.

[0039] Compared with the prior art, the utility model has the following advantages:

[0040] (1) The operating mechanism consists of an active module and a passive module. The active module and the passive module each have an energy storage process and a limit. During the movement, the handle directly acts on the active module. The active module can push the execution module to move, but the passive module does not drive the active module. The two sets of modules are not completely locked during the opening and closing movement, so that the operating speed of the personnel is independent of the movement speed of the module, realizing the rapid opening and closing of the contacts, shortening the existence time of the arc, and greatly improving the safety of the switch.

[0041] (2) The rotation angle of the operating mechanism reaches 90°, which enables the contacts to have a larger opening and closing angle, further reducing the impact of the arc on the switch during opening and closing.

[0042] (3) The operating mechanism can be operated from both the top and the side, making the operation method more diversified and suitable for different installation scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0103] Here’s how it works:

[0104] In the utility model, the operating mechanism comprises an active module and a driven module.

[0105] The first bracket 3, the first spring 4, the first gear 5, the second gear 6, the first shaft 9 and the second shaft 10 constitute an active module; the third shaft 11, the splint 12, the retaining ring 13, the sleeve 14, the amplifying rod 15, the slider 16, the slide bar 17, the rocker rod 18, the gasket 19, the second spring 20, the fourth shaft 21, the sixth shaft 22, the fifth shaft 23, the crank 24, the synchronization rod 25, and the seventh shaft 26 constitute a driven module.

[0106] like Fig.32 As shown, when the switch starts to close, the first gear 5 rotates clockwise, and the first side plate 7 also starts to move clockwise. When the first side plate 7 rotates to a certain angle around the second hole 1d, one end of the tenth slot 7a on the first side plate 7 contacts the slide bar 17 and pushes the slide bar 17 to move around the third axis 11. The slide bar 17 drives the clamping plate 12 to move clockwise around the third axis 11. At the same time, the slide bar 17 moves downward along the sixteenth slot 18c, driving the swing rod 18 to move counterclockwise around the seventh axis 26. In this process, the slide bar 17 and the clamping plate 12 push the gasket 19 to move downward, compressing the second spring 20.

[0107] In addition, the slide bar 17 moves in the nineteenth groove 15b, driving the amplifying rod 15 to move clockwise around the sixth axis 22. The amplifying rod 15 forms a connecting rod mechanism with the crank 24 and the synchronization rod 25. The height of the rotation center of the amplifying rod 15 is lower than the height of the rotation center of the clamping plate 12, so it can play a role in amplifying the rotation angle of the clamping plate 12. The rotation angle of the clamping plate is 90°, and the rotation angle of the amplifying rod is 180°. The fourth axis 21 can slide in the fourteenth groove 16a of the slider 16.

[0108] Before the driven module passes the dead point, the slider 16 does not move because the fourth shaft 21 moves in the fourteenth groove 16a. Fig.31As shown, when the two-link module composed of the clamping plate 12 and the rocker 18 passes the dead point (the clamping plate 12 and the rocker 18 are located on the same straight line), the second spring 20 is released, the slide bar 17 is out of contact with the first side plate 7, the second spring 20 drives the driven module to move, the fourth shaft 21 contacts the slider 16, and the movement of the amplifying rod 15 can be transmitted to the slider 16 in a 1:1 ratio, thereby driving the slider 16 to rotate clockwise. When the twenty-first boss 16d contacts the fifth boss 1i, the driven module reaches the closing position and the movement stops. The active module is driven by the first spring 4. When it rotates to the eleventh groove 8a and contacts the seventh boss 1k, the active module reaches the closing position and the movement stops.

[0109] like Fig.30 As shown, when the gate starts to open, the first gear 5 rotates counterclockwise, and the first side plate 7 also starts to move counterclockwise. When the first side plate 7 rotates to a certain angle around the second hole 1d, one end of the tenth slot 7a on the first side plate 7 contacts the slide bar 17 and pushes the slide bar 17 to move around the third axis 11. The slide bar 17 drives the clamping plate 12 to move counterclockwise around the third axis 11. At the same time, the slide bar 17 moves downward along the sixteenth slot 18c, driving the swing rod 18 to move clockwise around the seventh axis 26. In this process, the slide bar 17 and the clamping plate 12 push the gasket 19 to move downward, compressing the second spring 20.

[0110] In addition, the slide bar 17 moves in the nineteenth groove 15b, driving the amplifying rod 15 to move counterclockwise around the sixth axis 22. When the two-link module composed of the clamping plate 12 and the rocker 18 passes the dead point (the clamping plate 12 and the rocker 18 are located on the same straight line), the second spring 20 is released, the slide bar 17 is out of contact with the first side plate 7, the second spring 20 drives the driven module to move, the fourth axis 21 contacts the slider 16, and the movement of the amplifying rod 15 can be transmitted to the slider 16 in a 1:1 ratio, thereby driving the slider 16 to rotate counterclockwise. When the twenty-first boss 16d contacts the fifth boss 1i, the driven module reaches the closing position and the movement stops. The active module is driven by the first spring 4. When it rotates to the eleventh groove 8a and contacts the seventh boss 1k, the active module reaches the closing position and the movement stops.

[0111] The second bracket 27 is clamped by the sixth boss 1j, the outer wall of the first slot 1b, and the inner walls of the first housing 1 and the second housing 2. The screw can be inserted through the contact module and cooperate with the seventeenth hole 27a to install the contact module. The twentieth slot 5c and the eighteenth slot 6b can both be equipped with handles, so that the top and side of the operating module can be opened and closed.
