DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figure 1-6 As shown, the utility model provides a dual power switch, including a switch body 1, a rotatable and adjustable switch member 9 is provided on the front side of the switch body 1, a plug hole 6 is provided on the front side of the switch member 9, a spring 7 is fixed on the inner wall of the plug hole 6, and a push plate 8 is fixed on the outward end of the spring 7;
[0027] A handle assembly 3 is provided at the front side of the switch body 1, and the handle assembly 3 includes a grip 303 located at the front side of the switch body 1, and a control arm 301 is fixedly provided at one end of the grip 303, and the control arm 301 extends toward one end of the switch body 1 to the side of the switch body 1 and is movably connected to the side of the switch body 1 through a bearing;
[0028] An end piece 304 is fixedly provided at the other end of the handle 303 . An insertion rod 305 penetrating through the end piece 304 is provided on the end piece 304 . One end of the insertion rod 305 facing the switch body 1 can be inserted into the inside of the insertion hole 6 .
[0029] When it is necessary to adjust the switching member 9, the handle 303 is held and the control arm 301 is rotated to drive the handle 303 to rotate, so that the insertion rod 305 at one end of the handle 303 rotates to the front of the switching member 9 and aligns with the socket 6, and then the insertion rod 305 is slid so that one end of the insertion rod 305 moves and is inserted into the socket 6. During this process, one end of the insertion rod 305 contacts the push plate 8 and pushes the spring 7, so that the spring 7 is compressed. When the insertion rod 305 is inserted into the socket 6, the handle assembly 3 is connected to the switching member 9. By rotating the handle 303 and the control arm 3 01 can drive the switching member 9 to rotate to realize the switching of the power supply. After the switching is completed, the plug rod 305 is released, the elastic force of the spring 7 is released and pushes the push plate 8 and the plug rod 305, so that the plug rod 305 is automatically moved out of the socket 6, and the connection between the handle assembly 3 and the switching member 9 is released. By operating the switching member 9 in this way, the switching member 9 can be connected when needed, and the connection between the handle assembly 3 and the switching member 9 can be automatically disconnected when not needed. In addition, the handle assembly 3 is connected to the switch body 1 to avoid loss, thereby further improving the anti-loss effect.
[0030] When not in use, the handle assembly 3 is automatically folded. Figure 2 , 3 As shown, a weight block 302 is fixedly provided at one end of the control arm 301 away from the switch body 1. The weight of the weight block 302 can make the handle 303 droop naturally. An insulating sleeve is fixedly provided at the outer end of the handle 303. During operation, the hand is held at the outer end of the insulating sleeve. Two limit plates are fixedly provided at the outer end of the insertion rod 305. The end piece 304 is located between the two limit plates. The insertion rod 305 can only slide between the two limit plates.
[0031] When the insertion rod 305 is removed from the inside of the socket 6, the grip 303 is released and the handle assembly 3 loses hand control. At this time, the weight of the weight block 302 causes the control arm 301 to rotate downward and the handle assembly 3 as a whole to rotate downward. The handle assembly 3 is therefore moved away from the front side of the switch body 1 and automatically folded.
[0032] In order to prevent dust while dissipating heat, Figure 1 , 5 As shown, a back plate 4 is detachably provided on the rear side of the switch body 1 , a heat dissipation component 5 is provided on the front side of the back plate 4 , and the heat dissipation component 5 is located at the bottom of the switch body 1 .
[0033] The heat dissipation assembly 5 includes a detachable rectangular channel 501 disposed on the front side of the back plate 4, a plurality of heat dissipation channels 502 are disposed inside the rectangular channel 501, both ends of the heat dissipation channels 502 are fixedly connected to the inside of the rectangular channel 501, and the rectangular channel 501 and the heat dissipation channels 502 are made of materials with good thermal conductivity and insulation;
[0034] A plurality of connecting pipes 503 are fixedly provided on the front side of the rectangular channel 501 , one end of the connecting pipe 503 is fixedly connected to the bottom end of the switch body 1 housing and communicates with the inside of the switch body 1 housing, and the other positions of the switch body 1 housing remain closed.
[0035] The shell of the switch body 1 is connected to the rectangular channel 501 through the connecting tube 503, while the other positions of the shell of the switch body 1 are in a closed state. The air in the shell of the switch body 1 is connected to the rectangular channel 501 only through the connecting tube 503. Therefore, the air in the shell of the switch body 1 can enter the rectangular channel 501 and the heat dissipation channel 502, and the air is cooled by the high thermal conductivity of the two. This method can not only dissipate heat for the switch body 1, but also prevent dust from entering the switch body 1.
[0036] When the switch member 9 is operated by the handle assembly 3, in order to improve safety, Figure 1 , 6 As shown, a shielding assembly 2 is provided on the front side of the switch body 1, and the handle assembly 3 is located between the switch body 1 and the shielding assembly 2. The shielding assembly 2 includes a transparent baffle 202 located in front of the switch body 1, and a frame 201 is fixedly provided on the outer end of the transparent baffle 202.
[0037] An adjustment arm 203 is provided on one side of the frame 201 through damping rotation. The end of the adjustment arm 203 facing the switch body 1 is movably connected to the side of the back plate 4 through a damping shaft, so that the shielding assembly 2 can be folded and stored when not in use.
[0038] When the switching member 9 is controlled by the handle assembly 3, the adjustment arm 203 and the frame 201 are rotated to move the transparent baffle 202 to the front of the switch body 1 and the handle assembly 3. The operator can observe the switch body 1 and the handle assembly 3 through the transparent baffle 202 without affecting the adjustment of the switching member 9. The transparent baffle 202 is between the operator's face and the switch body 1. When an accident such as a fire occurs in the switch body 1, the transparent baffle 202 can protect the operator's face and improve the safety of the operation.

The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
