The surface of the rotating disk 130 coaxially fixed with the rotating shaft 110 is connected with a damping member 140, which can provide damping when the isolating switch rotates to prevent it from suddenly rotating or stopping too quickly, thereby ensuring smooth operation. In addition, the isolating switch body 100 is also rotatably installed with a screw rod 150, which is used to push the damping member 140 to slide radially along the rotating disk 130 to adjust the damping size to meet different operating requirements. This design not only improves the convenience of operation of the isolating switch, but also enhances the safety and comfort of use by adjusting the damping.

[0028] In a specific implementation of the present invention, the rotary disk 130 is installed in the isolating switch body 100, one end of the screw rod 150 extends to the outer surface of the isolating switch body 100, and the end of the screw rod 150 extending to the outer surface is provided with a hexagonal groove 152.

In addition, a bearing that matches the screw rod 150 is also provided in the isolating switch body 100, and the rotation resistance of the screw rod 150 is reduced by the bearing support.

The rotating disk 130 can rotate in the receiving groove 101, thereby realizing the rotation function of the rotating shaft 110 connected to the isolating switch body 100. In addition, the damping member 140 is slidably arranged in the receiving groove 101, and the function of the damping member 140 is to provide additional resistance to slow down the speed of the rotating disk 130 during the rotation process, thereby ensuring the stability and safety of the isolating switch body 100 during operation. This design not only improves the durability of the isolating switch body 100, but also ensures the smoothness and safety of its operation.

[0032] In a specific implementation of the present utility model, a guide groove is opened at the top of the accommodating groove 101, and the upper end of the damping member 140 is slidably engaged in the guide groove, and the lower end of the damping member 140 contacts the upper surface of the turntable 130, and the upper surface of the turntable 130 is provided with a friction surface.

[0033] A guide groove is provided at the top of the receiving groove 101, and the upper end of the damping member 140 is designed to slide and engage in the guide groove to guide the damping member 140 and ensure its stable guidance. The lower end of the damping member 140 is in direct contact with the upper surface of the rotating disk 130. The upper surface of the rotating disk 130 is provided with a friction surface to increase the friction between the damping member 140 and the damping member 140, further improving the effect of the rotation resistance.

[0034] In a specific implementation of the utility model, a support plate 160 is fixed in the receiving groove 101, one end of the screw rod 150 is rotatably engaged with the support plate 160, a rotating hole is opened on the side wall of the receiving groove 101, and the other end of the screw rod 150 rotates through the rotating hole.

[0035] The support plate 160 fixed in the receiving groove 101 is used to support the screw rod 150 to ensure its stable rotation. One end of the screw rod 150 is rotatably connected to the support plate 160. This design allows the screw rod 150 to rotate on the support plate 160 while maintaining a fixed position. A rotating hole is opened on the side wall of the receiving groove 101, and the rotating hole is used to allow the other end of the screw rod 150 to rotate through, so that the screw rod 150 can rotate freely. This structure allows the screw rod 150 to be used as a transmission component, and the damping member 140 is driven to slide by rotating the screw rod 150.

[0036] In a specific implementation of the present invention, the damping member 140 includes a slider 142 and a brake pad 143 . The brake pad 143 is disposed at the lower end of the slider 142 , and the lower surface of the brake pad 143 is in contact with the upper surface of the rotating disk 130 .

[0037] The damping member 140 is a structure that increases resistance and is a mechanical device used to slow down or stop the moving parts of a machine. Its core components include a slider 142 and a brake pad 143. The slider 142 is designed to slide in the mechanical system, and the brake pad 143 is arranged at the lower end of the slider 142 to contact the turntable 130 to generate friction, thereby achieving the function of deceleration or stopping. The lower surface of the brake pad 143 fits tightly with the upper surface of the turntable 130, ensuring that when necessary, the change in the position of the damping member 140 can effectively change the resistance to the rotation of the turntable 130, thereby improving the stability and reliability of the mechanical system.

[0038] In a specific implementation of the present invention, a threaded hole 141 is opened on the surface of the slider 142 , the screw rod 150 is threadedly penetrated through the threaded hole 141 , and an elastic member 144 is connected between the upper surface of the brake pad 143 and the slider 142 .

[0039] The surface of the slider 142 is provided with a threaded hole 141 for cooperating with the screw rod 150. The screw rod 150 is connected to the slider 142 through the threaded hole 141. The upper surface of the brake pad 143 is connected to the slider 142 through an elastic member 144, which can provide necessary elastic force support when the slider 142 and the screw rod 150 move relative to each other, thereby ensuring that the brake pad 143 can still fit closely to the surface of the rotating disk 130 after being worn, and achieve an effective blocking effect. The device has a simple structure and low manufacturing cost.

[0040] In a specific implementation of the present utility model, the slider 142 is provided with a receiving cavity, the elastic member 144 is arranged in the receiving cavity, the upper end of the brake plate 143 is slidably engaged in the receiving cavity, and the elastic member 144 is a compression spring;

[0041] The slider 142 has a structure for accommodating and fixing an elastic member 144. The elastic member 144 is specifically a compression spring, which is arranged in the accommodating cavity and has the function of providing a rebound force for the brake pad 143. The upper end of the brake pad 143 is designed to be slidably engaged in the accommodating cavity, which means that the brake pad 143 can slide in the accommodating cavity of the slider 142 in the up and down directions. This design enables the brake pad 143 to slide downward to compensate after wear so as to fit the surface of the turntable 130.

[0042] In a specific implementation of the present utility model, a retaining spring is clamped in a clamping groove provided on the surface of the screw rod 150 , and the retaining spring is arranged at one end of the rotating hole.

[0043] The working principle of the electric isolating switch with adjustable rotational resistance: when in use, the damping member 140 is in frictional contact with the surface of the turntable 130, so as to increase the resistance to the rotation of the shaft 110. In the process of driving the damping member 140 along the turntable 130 radially toward the edge by the screw rod 150, due to the lever principle, the resistance to the rotation of the shaft 110 will gradually increase. By adjusting the position of the damping member 140 on the surface of the turntable 130 as needed, the resistance to the rotation of the turntable 130 can be changed, and then the resistance to the rotation of the shaft 110 driven by the knob 120 can be adjusted, thereby realizing the function of the electric isolating switch with adjustable rotational resistance.

[0044] It should be noted that the lower surface of the turntable 130 is provided with a plane bearing to provide sufficient support force to maintain stability; the turntable 130 is made of the material of the automobile brake pad, and the brake pad 143 is also called a brake pad. In the braking system of the automobile, the brake pad 143 is the most critical safety part, and the brake pad 143 plays a decisive role in all braking effects. The brake pad 143 is generally composed of a steel plate, an adhesive heat insulation layer and a friction block, wherein the heat insulation layer is composed of a non-heat-conducting material for the purpose of heat insulation; the friction block is composed of friction material and adhesive, and is squeezed on the brake disc and brake drum to generate friction during braking, thereby achieving the purpose of vehicle deceleration and braking. In this application, the existing brake pad 143 is cut or customized as needed to achieve the required shape and size for use in this solution.
