Description of the invention [Technical field to which the invention belongs] The present invention relates to a spring operator for a shutter, which uses a stored energy of a spring to drive a movable part of a shutter such as a disconnect switch. [Prior Art] A spring operator is used to open or close a switch such as a disconnect switch. Fig. 4 is a perspective view of a conventional spring operator for a shutter. The spring operator for the shutter is operated to open or close the disconnect switch through an operating rod connected to a connecting rod mounted on the output shaft. In FIG. 4, the worm gear 4 connected to the worm shaft 2 directly connected to the output shaft of the gear motor 1 is used to reduce the gear motor 1, and the elbow that is engaged by 4 a and 5 a of the engaging section is used. The articulation lever 5 causes the worm wheel 4 to rotate. Alternatively, the manual operation handle 4 may be connected to the operation shaft 2d of the helical gear 2b instead of rotating the gear motor 1. As the toggle lever 5 is rotated, the compression end is fixed so that one end is connected to the toggle spring 8 on the toggle lever 5. When the toggle lever 5 and the toggle spring 8 become a straight line forming a dead point, the toggle spring 8 can reach the maximum compression amount, and then the moment when the toggle lever 5 rotates beyond the dead point of the toggle spring 8, The toggle spring will begin to release energy and the toggle lever 8 will move quickly. At this time, the engagement between the toggle lever 5 and the worm wheel 4 will be released. The toggle lever 5 is used to drive the toggle lever 5 by the energy released by the toggle spring 8. The engaging section 5b of the toggle lever 5 and the lever 9 The engaging lever 9 is driven by the engagement of the engaging section 9a, and is driven by a fork-shaped fork lever 12 which is engaged with the roller 1 -5- (2) (2) 200405377 provided on the lever 9. The output shaft 11 is turned on or off by the operation lever 15 connected to the connecting rod 13 of the output shaft 11. Fig. 5 is a schematic diagram showing the characteristics of the load torque and the output torque of the conventional spring operator. In the conventional spring manipulator system, at the dead point, when the output shaft starts to move, the load of the toggle spring is large and the moment arm of the toggle lever is small, but when the output shaft stops moving, the moment arm of the toggle lever is large and The load of the toggle spring is small, so the moment of the toggle lever will become a mountain-shaped characteristic with a sharp peak during the movement. On the other hand, the characteristics of the load applied to the shutter of the spring manipulator 'must require a large torque at the beginning of the stroke or at the end of the stroke, so' the fork lever is used to transform it to have a bottom during the movement. Bath-shaped characteristics [Content of the invention] [Problems to be solved by the invention] As shown in Fig. 5, the load characteristics of the shutter are very different when opened and closed. On the other hand, the torque characteristics transformed by the fork lever will inevitably have the same characteristics during opening and closing, and excessive torque will be generated at the beginning and end of the stroke. Subject. (1) Since unnecessary energy will be released, the spring load will become more than necessary and the size of the manipulator will also increase. -6- (3) (3) 200405377 (2) As excessive torque will occur at the end of the stroke, the cushioning device will tend to be a large cushioning device. (3) The losses caused by the sliding friction of the fork rod part are huge. Therefore, the present invention is to provide a spring operator for a shutter that can arbitrarily set the input and output torque characteristics and realize the torque characteristics corresponding to the load. [Measures taken to solve the problem] The present invention is directed to interconnecting a pivotable toggle lever and a toggle spring. When the toggle lever rotates, the toggle lever and the toggle spring will form a dead point, and The moment the toggle lever is rotated beyond the aforementioned dead point, the toggle lever will quickly start to move. The spring of the shutter is opened or closed by the rotation of the output shaft driven by the toggle lever. A relay shaft and a connecting rod are provided between the toggle control lever and the toggle spring. With the setting of the lever angle of the relay shaft, the input and output torque characteristics can be set arbitrarily to achieve the torque characteristics corresponding to the load. It has the characteristics of changing the torque characteristics of the output shaft according to the rotation direction. When the rotation direction of one side is larger than the rotation period, the rotation direction of the other side is from the rotation period. Small output shaft torque characteristics. [Embodiment] FIG. 1 is a perspective view of a spring manipulator of the present invention. Although the drawing near the gear motor and the worm shaft is not shown in the drawing in the first figure ', but it is different from the conventional spring manipulator in Fig. 4 • 7-(4) 200405377 gear motor and worm shaft No difference. 'The spring manipulator of the present invention is shown in FIG. 4' The output shaft of the gear motor 1 is directly connected to the worm shaft 2 provided with a helical tooth 2 a at the front end, and the helical tooth 2 a is The worm wheel 4 is engaged with the worm wheel 4 with the shaft 3 as a free rotation axis. The worm shaft 2 can be rotated by driving the gear motor 1 to reduce the rotation of the worm wheel 4. In addition, like the conventional spring manipulator, a helical gear 2 b is provided on the worm shaft 2, and a manual operation handle 2 can be connected to the operation shaft 2 d of the helical gear 2 b to rotate the worm shaft. · The toggle lever 5 adjacent to the worm wheel 4 can rotate freely with the axis 3 as the axis. On the worm wheel side of the toggle lever, there is an engaging section portion 5a which is engaged with the engaging section portion 4a of the worm wheel 4. After the engaging portions 4a and 5a of the two are engaged, the The toggle lever 5 is turned. One end of the connecting rod 6 is connected to the toggle control lever 5 and allowed to rotate freely, and the other end of the connecting rod 6 is connected to the relay lever 7 with the axis 7 a as the rotation axis and allowed to rotate freely. . The other end of the relay lever 7 is connected to the other end of the toggle spring 8 which is fixed on one side and allows it to rotate freely. By the rotation of the toggle lever 5, the relay lever 7 will also start to rotate and compress the toggle spring 8 through the connecting rod 6. The link lever 13 adjacent to the toggle lever 5 is arranged to be freely rotatable, and the toggle lever side of the link lever 13 has an engagement section 5 b that is engaged with the toggle lever 5 of the toggle lever 5 Segment part 3a, through the engagement of the two engaging part parts 5b and 1a, the toggle lever 5 can cause the connecting rod 3 to rotate. The engaging section portion 5 b of the toggle lever 5 and the engaging section portion 1 3 a of the connecting rod i 3 are configured such that when the compressed toggle spring s becomes -8- 108 (5) (5) 200405377 is dead When clicked, they will engage each other. The operating lever 15 of the disconnect switch i 4 is connected to the connecting lever 13. Next, the spring operator of the present invention will be described. Figures 2 (a) to (b) are schematic diagrams showing the state of change of the toggle lever and toggle spring. If the worm shaft 2 is rotated using the gear motor 1 or the manual handle 2 c from the closed state, the worm wheel 4 will start to rotate, and the engagement section 4 a of the worm wheel 4 and the toggle of the toggle lever 5 The engagement of the joint portion 5 a can cause the toggle lever 5 to rotate clockwise. After the rotation of the toggle lever 5 passes through the connecting rod 6, the relay lever 7 can be rotated counterclockwise, and the toggle spring 8 is compressed. (Refer to Figure 2 (a)) As the worm wheel 4 rotates, the toggle lever 5 will continue to rotate. When the toggle lever 5 and the connecting lever 6 become a straight line, the toggle lever 5 will become Dead point state where torque has no effect. (Refer to Figure 2 (b)) When the rotation is further beyond this dead point, the rotation direction of the relay lever 7 will be reversed to the clockwise direction, and the toggle spring 8 will be freed from the compressed state. The toggle lever 5 is turned clockwise, so that the connecting rod] 3 is turned clockwise, and the disconnect switch 1 4 is switched to the on state through the operation rod connected thereto. As shown in FIG. 3, the present invention has the characteristics of changing the torque characteristics of the output shaft according to different rotation directions. It can be obtained that when the rotation direction on one side is larger in the initial period than in the last period, the rotation direction on the other side is Turn-9- (6) 200405377 The torque characteristics of the output shaft are smaller at the beginning of the movement than at the end of the rotation. [Effects of the Invention] The present invention is provided with a relay shaft and a connecting rod between the toggle control lever and the toggle spring. The input and output torque characteristics can be arbitrarily set by setting the connecting rod angle of the relay shaft to achieve corresponding load. Torque characteristics. By suppressing the release of unnecessary energy, the operator can be made more compact. Because it can suppress the excessive torque generated at the end of the stroke, the buffer device can also be made smaller.
