[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 It includes a bearing seat 1, a support seat 2, a first transmission gear 3, a fixing hole 4, a first fixing seat 5, a second transmission gear 6, a drive block 7, a bearing 8, a second fixing seat 9, a transmission shaft 10, and a bolt 11;

[0027] The drive mechanism of the drive shaft 10 consists of a support base 2, a first drive gear 3, a second drive gear 6 and a drive shaft 10. The first drive gear 3 and the second drive gear 6 play a core role in the drive process, and they drive the drive shaft 10 to rotate with the help of an external drive device.

[0028] The support base 2 is located on the surface of the bearing base 1 and is connected to the bearing base 1 by bolts 11 on the side of the fixing hole 4. This connection method is not only stable and reliable, but also facilitates the disassembly and installation of the equipment, providing convenience for the maintenance and repair of the equipment. The upper part of the support base 2 adopts a rotating connection structure, which allows the first transmission gear 3 to rotate flexibly.

[0029] The first transmission gear 3 is mounted on the support base 2, and a square groove is provided at the center point of its side. The purpose of this groove is to facilitate the connection of external drive components. When the external drive components are running, they can drive the first transmission gear 3 to rotate. The first transmission gear 3 adopts a helical gear structure, which makes the meshing of the gears more stable during the transmission process and effectively reduces impact and noise.

[0030] The second transmission gear 6 meshes with the first transmission gear 3. When the first transmission gear 3 rotates, it will drive the second transmission gear 6, which meshes with it, to rotate synchronously. Since the second transmission gear 6 is fixedly connected to the transmission shaft 10, the rotation of the second transmission gear 6 can directly drive the transmission shaft 10 to rotate.

[0031] The fixing mechanism consists of a first fixing seat 5, a bearing 8, a second fixing seat 9, and a transmission shaft 10. The bearing seat 1, the first fixing seat 5, and the second fixing seat 9 work together to firmly fix all the components together.

[0032] The surface of the support base 1 is provided with fixing holes 4, which can be quickly disassembled and installed with different accessories according to different needs, significantly improving the compatibility of the equipment and enabling the equipment to adapt to a variety of working scenarios;

[0033] The first fixed seat 5 is connected to the upper part of the bearing seat 1 by bolts 11. The bearing 8 is embedded inside and is connected to the transmission shaft 10. This connection method can provide stable support for the transmission shaft 10 and reduce the frictional resistance when the transmission shaft 10 rotates.

[0034] The second fixed seat 9 is designed with a T-shaped structure below. This structure increases the contact area between the second fixed seat 9 and the bearing seat 1, thereby improving the stability of the connection. The second fixed seat 9 and the bearing seat 1 are also connected by bolts 11. A bearing 8 is also embedded in the upper part of the second fixed seat 9. The drive shaft 10 is installed between the two second fixed seats 9 and the surface is fitted with the bearing 8. This design ensures that the drive shaft 10 can rotate smoothly under stable support.

[0035] The bearing seat 1 is made of high-strength alloy material in one piece. This material itself has high strength and toughness and can withstand large external forces. At the same time, it has a crisscrossing reinforcing rib structure inside, which further enhances the overall strength and rigidity of the bearing seat 1, so that it can effectively resist external deformation and ensure the stable operation of various components installed on it.

[0036] The drive shaft 10 is made of high-quality alloy steel and undergoes special heat treatment processes such as quenching and tempering. Quenching can make the surface hardness of the drive shaft 10 reach HRC55-60, improving its wear resistance; tempering can make the core of the drive shaft 10 maintain good toughness, enhance its fatigue resistance, and thus extend the service life of the drive shaft 10.

[0037] Both the first transmission gear 3 and the second transmission gear 6 are machined using high-precision gear grinding technology. This process ensures the gear tooth profile accuracy and surface quality, making the gears more precise and stable during meshing. It effectively reduces noise and vibration during transmission, and improves the operating efficiency and reliability of the equipment.

[0038] Three drive blocks 7 are fitted onto the surface of the drive shaft 10. They are evenly distributed on the surface of the drive shaft 10. The drive blocks 7 have a tapered structure at the top and an opening at the bottom. They are connected to bolts 11 by threads on the sides. Tightening the bolts 11 can firmly fix the drive blocks 7 to the drive shaft 10, ensuring that the drive blocks 7 can rotate synchronously with the drive shaft 10 to achieve a specific driving function.

[0039] Working principle: When using this high-strength integrated electric control switch isolating knife drive shaft, the external drive device (such as a motor) is started, and its output power drives the first drive gear 3 to rotate. Since the first drive gear 3 is a helical gear structure and meshes with the second drive gear 6, the rotation of the first drive gear 3 can smoothly drive the second drive gear 6 to rotate. The second drive gear 6 is fixedly connected to the drive shaft 10, thereby driving the drive shaft 10 to rotate synchronously. The drive block 7 on the surface of the drive shaft 10 rotates with the drive shaft 10. The conical structure above it cooperates with the isolating knife and other related components to convert the rotation of the drive shaft 10 into the linear motion or other specific actions of the isolating knife, realizing the opening and closing operations of the electric control switch isolating knife. In the whole transmission process, the bearing seat 1, the first fixed seat 5 and the second fixed seat 9 are connected by bolts 11 to form a stable support structure. The bearing 8 provides low-friction rotational support for the drive shaft 10, ensuring the smooth rotation of the drive shaft 10 and reducing wear and vibration.

[0040] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
