The upper end of the support insulating column 2 is provided with a conductive plate 21 and a connecting seat, and the connecting seat fixes the conductive plate 21 on the upper end of the support insulating column 2 through a bolt.
One end of the main knife 3 is hinged on one of the connecting seats, and one end of the main knife 3 away from the hinged point is provided with a main knife moving contact 31. Wherein, the conductive plate 21 is arranged at one side far away from the hinge point of the main knife 3, and the main knife contact plate 22 and the ground knife contact plate 23 are arranged on the conductive plate 21. One end of the earthing knife 4 is provided with an earthing knife moving contact 41 for abutting against the earthing knife contact plate 23.
The main blade contact plate 22 is vertically disposed, and the upper end of the main blade contact plate inclines towards the side far away from the main blade 3, so that when the main blade 3 rotates towards the main blade contact plate 22, the main blade moving contact 31 can smoothly abut against the main blade contact plate 22, and the phenomenon of blocking is reduced. The two sides of the main blade moving contact 31 extend to form the abutting plates 32, and correspondingly, the two sides of the main blade contact plate 22 are provided with notches 221. When the contact plate 32 horizontally overlaps the notch 221, the main blade moving contact 31 contacts the main blade contact plate 22. The conductive plate 21 is located on one side of the hinge point of the main knife 3, the conductive plate 21 is connected with a soft copper bar 24, and the conductive plate 21 is connected with the main knife 3 through the soft copper bar 24 to keep the electric conduction state between the conductive plate 21 and the main knife 3.
The two sides of the moving contact 41 of the ground cutter are both provided with guide glue 42, and the two guide glue 42 form a flaring structure. When the ground cutter rotates towards the ground cutter contact plate 23, the flaring formed by the two guiding rubbers 42 faces the ground cutter contact plate 23 to play a guiding role, so that the ground cutter moving contact 41 can be smoothly abutted against the ground cutter contact plate 23.
The middle position of the mounting seat 1 is rotatably provided with a main knife transmission shaft 5 in a penetrating way, and the main knife transmission shaft 5 is horizontally arranged and is vertical to the main knife 3.

One end of the transmission rod 51 is fixed on the main cutter transmission shaft 5, and the other end is hinged with the transmission insulating column 52; the other end of the transmission insulating column 52 is hinged with the side wall of the middle part of the main knife 3. The transmission part can be driven to move by the rotation of the main cutter transmission shaft 5, so that the main cutter 3 rotates around the hinged point of the main cutter.
One side of the mounting seat 1 is rotatably provided with a ground cutter transmission shaft 6 through a connecting plate, and the ground cutter transmission shaft 6 is parallel to the main cutter transmission shaft 5. The ground cutter 4 is perpendicular to the ground cutter transmission shaft 6. One end fixedly connected with ground sword fixing base 61 of ground sword 4, and ground sword fixing base 61 is fixed in on ground sword transmission shaft 6 through U type bolt 62, and U type bolt 62 encircles in the outer wall of ground sword transmission shaft 6.
The linkage component is used for driving the main knife transmission shaft 5 and the ground knife transmission shaft 6 to rotate, and further driving the main knife 3 and the ground knife 4 to rotate. When the main knife 3 is abutted against the main knife contact plate 22, the ground knife 4 is in a brake-off state; when the ground knife 4 abuts against the ground knife contact plate 23, the main knife 3 is in a brake-off state. But does not indicate that the main knife 3 and the ground knife 4 must synchronously complete switching of switching-on and switching-off states; the ground knife 4 is firstly switched off, and the main knife 3 is switched on again.
The linkage assembly includes a vertical link 7, a rotation handle 71, and a linkage. The vertical connecting rod 7 is arranged vertically downwards, and one end of the vertical connecting rod 7 close to the ground can be driven by a motor or a human power to rotate. One end of the rotating handle 71 is mounted on the upper end of the vertical connecting rod 7 through a fixed seat, and the rotating handle 71 is perpendicular to the axis of the vertical connecting rod 7. And a fixing plate is connected among the vertical connecting rod 7, the main cutter transmission shaft 5 and the ground cutter transmission shaft 6 and is parallel to the mounting seat 1.
The linkage part comprises two parallel rotating rods 8 and a linkage rod 9. Two dwang 8 are installed on main sword transmission shaft 5 and ground sword transmission shaft 6 through the fixing base respectively, and two dwang 8 are parallel to each other. Two ends of the linkage rod 9 are respectively hinged on the same side of the two rotating rods 8.
An adjusting rod 72 is connected between the rotating handle 71 and the linkage member. Both ends of the adjusting rod 72 are rotatably connected with adjusting nuts 73, and the adjusting rod 72 and the adjusting nuts 73 can be rotatably connected through bearings. The adjusting nut 73 is threaded with a ball joint 74. One end of the adjusting rod 72 is ball-hinged with the rotating handle 71, and the other end is ball-hinged with the rotating rod 8 on the main cutter transmission shaft 5. The adjusting nut 73 is in threaded fit connection with the ball joints 74, and the distance between the two ball joints 74 can be adjusted within a small range by rotating the adjusting nut 73; therefore, the start and end positions of the main blade transmission shaft 5 are adjusted, so that the main blade 3 can stably contact the main blade contact plate 22 when the main blade is switched on.
Furthermore, one end of the rotating handle 71, which is far away from the vertical connecting rod 7, is provided with two adjusting holes 711 along the length direction of the rotating handle 71, wherein one adjusting hole 711 is connected with a ball stud 75 in a threaded manner, and the upper end of the ball stud 75 is hinged to the ball joint 74. The ball stud 75 is mounted in different adjusting holes 711, so that the initial and final positions of the main cutter transmission shaft 5 can be initially adjusted.
The working principle of the master-ground linkage type isolating switch in the embodiment of the application is as follows:
when the vertical connecting rod 7 rotates, the rotating handle 71 horizontally rotates, and the adjusting rod 72 drives the two rotating rods 8 to synchronously rotate, i.e. the main cutter rotating shaft 5 and the ground cutter transmission shaft 6 synchronously rotate. When the main cutter 3 is abutted against the main cutter contact plate 22, the ground cutter 4 is separated from the ground cutter contact plate 23; when the floor knife 4 abuts against the floor knife contact plate 23, the main knife 3 is separated from the main knife contact plate 22. The main knife 3 and the ground knife 4 complete switching-on and switching-off actions through one power output, the structure is simple, and the manufacturing cost is reduced to a greater extent.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
