Description

[0002] An isolating switch is a switch device that, when in the open position, has an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. Existing isolating switches usually require manual operation of the insulator to drive the knife switch (moving contact or conductive rod) to contact the static contact to achieve the opening and closing of the circuit. The isolating switch lacks a driving structure. At the same time, when the knife switch on the isolating switch is connected to the static contact, usually one knife switch can only control the opening and closing of one circuit. Multiple circuits require more isolating switches. Utility Model Content

[0009] Preferably, a motor is disposed inside the driving slider and an output end of the motor is fixedly connected to the bottom of the rotating shaft.
[0010] The utility model provides a driving structure for an isolating switch. Compared with the prior art, it has the following beneficial effects:
[0011] 1. A driving structure for an isolating switch, wherein a motor arranged inside a driving slider drives a top rotating shaft to rotate, and under the fixing action of a slide groove, the rotating shaft causes the driving slider to slide inside a second slide groove when rotating, thereby not changing the position of the rotating shaft in a vertical direction, and when the rotating shaft moves inside the slide groove, it drives an adjusting rod sleeved on the outside of the rotating shaft to slide inside a connecting hole, and drives a spring inside a connecting piece fixedly connected to the top of a fixing piece in the middle of the adjusting rod to deviate toward one end, and when the spring deviates, it drives a moving contact at the top of a crank arm fixedly connected to the other end, and under the fixing action of a fixing plate, it is snapped into the inside of a static contact to open a circuit, and when the fixing piece moves to both ends, the moving contact at the top of the crank arm is snapped into different static contacts to open or close different circuits.
[0012] 2. A driving structure for an isolating switch, through the elastic force of a spring, can drive a moving contact with a protrusion at one end of a crank arm fixedly connected at one end to be clamped inside a static contact to close the circuit under the action of the force driven by a driving slider when a rotating shaft clamped inside a slide slot of an adjusting rod. Since the circuits at both ends of the moving contact are in an open circuit state when the fixing part is in the middle of the isolating switch housing, after the isolating switch is disconnected, the breakdown voltage between the breaks must be greater than the breakdown voltage between the relative grounds to avoid the moving contact from being broken down, thereby ensuring the safety of maintenance personnel.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-4 The utility model provides a technical solution: a driving structure for an isolating switch. It includes a driving component 1, which includes a moving contact 112. The moving contact 112 is upwardly protruding on all sides and has an isolating switch housing 118 at one end. An adjusting rod 11 is slidably connected to the interior of the isolating switch housing 118. A fixing member 13 is fixedly connected to the middle of the adjusting rod 11. A connecting member 14 is fixedly connected to the top of the fixing member 13. A spring 110 is fixedly connected to the surface of the connecting member 14. The spring 110 is used to drive the moving contact 112 protruding at one end of a crank arm 19 connected at one end to engage or disengage from the interior of the static contact 113. A fixing plate 114 is fixedly connected to the bottom of the inner cavity of the moving contact 112. A crank arm 19 is rotatably connected to the top of the fixing plate 114. The moving contact 112 protrudes from the top of the crank arm 19. One end of the crank arm 19 is fixedly connected to the second connecting piece 111, one end of the adjusting rod 11 is fixedly connected to the side fixing plate 15, one end of the side fixing plate 15 extends to one side and is provided with a slide groove 16 inside, and a second slide groove 115 is provided on the side of the isolating switch housing 118, and a driving slider 17 is slidably connected inside the second slide groove 115, and a rotating shaft 18 is rotatably connected to the top of the driving slider 17. The motor arranged inside the driving slider 17 can drive the rotating shaft 18 to rotate. When the rotating shaft 18 rotates, due to the fixing effect of the slide groove 16, the driving slider 17 will be driven by the rotation force of the rotating shaft 18 to slide inside the slider 116, thereby changing the lateral position of the rotating shaft 18 and driving the adjusting rod 11 to slide inside the connecting hole 117.
[0020] See also Figure 1-4A slider 116 is protruded from one end of the rotating shaft 18, and the slider 116 is clamped on the outside of the slide slot 16, so as to fix the rotating shaft 18 inside the slide slot 16. One end of the spring 110 is fixedly connected to the inside of the connecting piece 14, and the other end of the spring 110 is fixedly connected to the inside of the second connecting piece 111. Static contacts 113 are fixedly connected to both ends of one side of the moving contact 112, and the width of the moving contact 112 is the same as the distance between the static contacts 113. A limiting block 12 is protruded from one end of the adjusting rod 11, and a motor is arranged inside the driving slider 17, and the output end of the motor is fixedly connected to the bottom of the rotating shaft 18.
[0021] When in use, firstly, the isolating switch is installed on the wall with screws, and the motor arranged inside the driving slider 17 drives the top rotating shaft 18 to rotate. Since the slider 116 protruding from the top of the rotating shaft 18 is clamped in the inside of the chute 16 protruding on one side of the side fixing plate 15 fixedly connected to the side of the adjusting rod 11, under the fixing effect of the chute 16, the rotating shaft 18 will make the driving slider 17 slide inside the slider 116 when rotating, so as not to change the position of the rotating shaft 18 in the vertical direction, and drive the sleeve connected to the rotating shaft 11 to move when moving inside the chute 16. The adjusting rod 11 on the outside slides inside the connecting hole 117, driving the spring 110 inside the connecting piece 14 fixedly connected to the top of the fixing piece 13 in the middle of the adjusting rod 11 to deviate to one end. When the spring 110 deviates, it drives the moving contact 112 on the top of the crank arm 19 fixedly connected to the other end, and under the fixing action of the fixing plate 114, the moving contact 112 on the top of the crank arm 19 is snapped into the inside of the static contact 113 to open the circuit. When the fixing piece 13 moves to both ends, the moving contact 112 on the top of the crank arm 19 is snapped into different static contacts 113 to open or close different circuits.
