DETAILED DESCRIPTION

[0032] The following will be described in detail below with reference to the accompanying drawings. Figures 1-6 The application is further described in detail.

[0033] The application discloses a disconnecting switch driving structure.

[0034] Reference will be made to Figure 1 The disconnecting switch driving structure comprises a shell 1 for mounting a static contact and a moving contact. One end of the shell 1 is provided with a mounting groove 2, and the inner side of the mounting groove 2 is provided with a driving piece 4. The driving piece 4 is connected with the moving contact in the shell 1 and is used to drive the moving contact to move, thereby completing the closing or opening of the disconnecting switch. A protective cover 3 is mounted on one side of the shell 1 and is used to protect the driving piece 4 from dust and the like.

[0035] Reference will be made to Figure 2 , Figure 3 The driving piece 4 comprises a positioning seat 41 fixedly mounted in the mounting groove 2, a rotating disc 42 rotatably connected to the upper end of the positioning seat 41, an operating shaft 43 penetrating the inner wall of the rotating disc 42, and a crankshaft 44 mounted in the middle of the operating shaft 43. The positioning seat 41 is used to ensure the stability of the whole structure. The rotating disc 42 is used to ensure the rotation efficiency of the operating shaft 43, and the inner wall of the rotating disc 42 is provided with a positioning piece 5 used to lock the operating shaft 43 in one direction, thereby ensuring the stability of the operating shaft 43. The side wall of the positioning seat 41 is provided with a through hole for allowing one end of the crankshaft 44 to rotate into, and the through hole is communicated with a slot opening for mounting the moving contact, thereby improving the connection efficiency of the crankshaft 44 and the moving contact. The two ends of the crankshaft 44 are fixedly connected with positioning rods 441, and the outer wall of the positioning rods 441 is rotatably connected with connecting plates 442 connected with the moving contact. When the operating shaft 43 drives the crankshaft 44 to rotate, the connecting plates 442 can drive the moving contact to move along the inner wall of the shell 1, thereby completing the closing or opening of the disconnecting switch.

[0036] Reference will be made to Figure 2 , Figure 3 and Figure 4A handle 6 is fixedly connected to the upper end of the operating shaft 43. Rotating the handle 6 drives the operating shaft 43 to rotate. A pointing element 7 connected to the operating shaft 43 is fixedly connected to one side of the handle 6. The lower side of the pointing element 7 is attached to the upper side of the protective cover 3 via the handle 6. Two protrusions 8 are fixedly connected to the upper side of the protective cover 3 for the pointing tip of the pointing element 7 to point to, so as to remind the user of the current status of the disconnecting switch (closed or open).

[0037] Reference Figure 3 , Figure 4 Both sides of the crankshaft 44 are fitted with retaining rings 45 that are connected to the operating shaft 43. The two retaining rings 45 can lock the groove on the outside of the operating shaft 43 to restrict the crankshaft 44 to the outer wall of the operating shaft 43, preventing the crankshaft 44 from moving up and down during operation, thus ensuring the stability of the structure and its service life.

[0038] Reference Figure 4 , Figure 6 The lower end of the positioning seat 41 is provided with a positioning hole 411 for the lower end of the operating shaft 43 to be inserted. The inner wall of the positioning hole 411 is rotatably connected to a limiting collar 412 connected to the outer wall of the lower end of the operating shaft 43. The limiting collar 412 is used to ensure the stability of the rotation of the operating shaft 43 on the inner wall of the positioning hole 411 and to prevent the lower end of the operating shaft 43 from being misaligned, thereby ensuring the stability of the closing or opening of the disconnecting switch.

[0039] Reference Figure 5 , Figure 6 The positioning component 5 includes a locking block 51 and multiple return springs 52. The inner wall of the turntable 42 has a positioning groove 421 for sliding the locking block 51. A toothed block 511 is fixedly connected to one side of the locking block 51. The upper end of the operating shaft 43 has a toothed groove 431 for inserting the toothed block 511. The connection between the toothed block 511 and the toothed groove 431 ensures that the operating shaft 43 is unidirectionally locked inside the turntable 42, guaranteeing the stability of the connection between the operating shaft 43 and the turntable 42. Multiple return springs 52 are fixedly installed between the locking block 51 and the inner wall of the positioning groove 421. The return springs 52 push the locking block 51 to slide along the inner wall of the positioning groove 421 until the toothed block 511 of the locking block 51 inserts into the toothed groove 431, ensuring the stability of the connection between the structures. During operation, the lower end of the operating shaft 43 is inserted into the turntable 42. As the operating shaft 43 is continuously inserted, it pushes the toothed block 511 and the locking block 51 back to the inner wall of the positioning groove 421. At this time, multiple return springs 52 retract until the lower end of the operating shaft 43 is inserted into the limiting collar 412. At this time, the toothed groove 431 is aligned with the toothed block 511. With the push of the extension of multiple return springs 52, the locking block 51 is pushed so that the toothed block 511 is inserted into the toothed groove 431, thus locking the operating shaft 43.

[0040] The implementation principle of the isolating switch driving structure of the embodiment of the application is as follows: in assembly, first, the moving contact and the stationary contact are installed in the shell 1, and then the positioning seat 41 is fixedly installed on the inner wall of the installation groove 2; second, the connecting piece 442 is installed on the outer side of the positioning rod 441 at one end of the crankshaft 44, and then the other end of the connecting piece 442 is connected with the main shaft of the moving contact; third, the operation shaft 43 is inserted into the rotating disc 42 at the top of the positioning seat 41, and then the continuous insertion of the operation shaft 43 will push the clamping block 51 and the toothed block 511 to retract to the inner wall of the positioning groove 421, so that the plurality of reset springs 52 perform a contraction action; then, the operation shaft 43 is inserted through the crankshaft 44 until the operation shaft 43 is inserted into the inner wall of the limiting sleeve ring 412 in the positioning hole 411, at this time, the toothed groove 431 on one side of the operation shaft 43 is aligned with the toothed block 511, and then the plurality of reset springs 52 perform an extension action to push the toothed block 511 to be inserted into the toothed groove 431, thereby completing the locking of the operation shaft 43; fourth, the two buckling rings 45 are moved to be buckled on the outer wall of the operation shaft 43 and respectively abut against the upper and lower sides of the crankshaft 44, thereby completing the limitation of the crankshaft 44; and finally, the protective cover 3 is fixedly installed on the upper side of the installation groove 2, and the upper end of the operation shaft 43 is extended out of the protective cover 3, then the handle 6 is fixed on the upper end of the operation shaft 43 until the pointing piece 7 abuts against the upper side of the protective cover 3, thereby completing the installation of the driving structure.
