応できるように改良したものである。[Detailed description of the invention] This invention relates to an operating mechanism using a mainspring spring as an operating source used in switches such as chopsticks and disconnectors, and is designed to be easily applicable especially when large output or small output is required. This is an improved version.

り、部品点数が増加する欠点もある。 Generally, in the operation mechanism of a switch, energy is stored in advance in an operation source such as a coil spring, a disc spring, or a mainspring spring by a drive source such as a motor, and when the switch is closed or opened, energy is stored in advance. It performs its operations by releasing the source's energy all at once. For operating mechanisms that use a mainspring as an operating source, if high output is required, this can be achieved by increasing the thickness of the mainspring or increasing the number of turns of the mainspring. Ta. However, in this case, there are disadvantages such as the difficulty of manufacturing the mainspring itself increases as the plate thickness increases or the number of turns increases, and the mainspring spring barrel also has to be made larger in diameter. Furthermore, it is necessary to manufacture a mainspring spring and a mainspring spring barrel each having a different plate thickness or number of turns depending on the output required for the opening/closing operation of the switch, which also has the disadvantage of increasing the number of parts.

Reference numeral 3 denotes a drive shaft for operation, and this drive shaft 3 is rotatably supported and has an operating lever 4 fixed to one end thereof, which is connected to a switch (not shown) for opening/closing operations. . Reference numeral 5 designates a mainspring spring device, in which a mainspring spring 7 is housed inside a mainspring spring barrel 6 rotatably disposed around the outer periphery of a shaft 3a connected to the other end of the drive shaft 3. The outer peripheral end of the spring 7 is fixed to the mainspring spring barrel 6, and the inner peripheral end thereof is fixed to the shaft 3a. The mainspring spring device 5 is a mainspring spring device in which the mainspring barrel 6, the mainspring spring 7, and the shaft 3a are each made of the same material and formed in the same shape so as to generate a certain output, and emit a certain amount of energy. 5, and one or more (two in the figure) are arranged depending on the output required for the opening/closing operation of the switch. That is, the mainspring spring barrel 6 is formed with a flange portion 6a, and this flange portion 6a
By connecting with bolts 6b etc.
A plurality of the mainspring spring barrels 6 are configured to be easily connectable. Further, the shaft 3a is configured so that a plurality of shafts 3a can be easily connected by a square hole or a pin (not shown) so that rotational force can be transmitted.

Reference numeral 8 denotes a mechanism control unit that controls the closing operation or opening operation of the operating mechanism. To explain a part of this mechanism control part 8, 8a is a cam fixed to the drive shaft 3, 8b is a stopper that engages with or separates from the cam 8a, and the rotation of the drive shaft 3 is controlled by operating the stopper 8b. To regulate or deregulate. Note that 8c is a spring that biases the stopper 8b.

に行われる。 Next, the operation of the switch operating mechanism according to the above-described embodiment will be explained. With the stopper 8b engaged with the cam 8a, the drive source 1 is operated and its output shaft 1a is activated.
When rotated, the rotation of the worm 2 is transmitted to the worm wheel 6c of the mainspring spring barrel 6, and the mainspring spring barrel 6 rotates in the clockwise direction A. At this time, since the cam 8a is engaged with the stopper 8b, the drive shaft 3 and the shaft 3a connected to the drive shaft 3
cannot rotate, energy is accumulated in the mainspring spring 7 as the mainspring barrel 6 rotates. When closing or opening the switch, the engagement between the cam 8a and the stopper 8b is released. When the stopper 8b is actuated in the direction of arrow B to release the engagement, the energy stored in the mainspring spring 7 causes the drive shaft 3 to rotate clockwise A at once via the shaft 3a, and This rotational force is then transmitted to the switch to perform the closing or opening operation. Note that when energy is released, the worm wheel 6c and the worm 2 are in mesh with each other, so the mainspring spring barrel 6 itself does not rotate at all, but only the shaft 3a and the drive shaft 3 rotate, and the opening/closing operation described above is performed smoothly. It will be held on.

The spring spring device 5 is 1
All you have to do is place them individually. That is, one or more mainspring spring devices 5 may be disposed on the drive shaft 3 depending on the output required for opening/closing the switch connected to the operating lever 4.
