[0025] Reference Figure 1-10The dual power automatic transfer switch proposed by the present invention comprises a base 1, a slide bar 5 is fixedly connected to the base 1, a connecting tube 6 is slidably connected to the slide bar 5, a fixed wiring terminal 601 is fixedly connected to the connecting tube 6, a first conversion terminal 602 and a second conversion terminal 603 are arranged on the connecting tube 6, the first conversion terminal 602 and the second conversion terminal 603 are staggered, a fixed tube 10 coaxial with the connecting tube 6 is fixedly connected to the base 1, an adjustment port 11 adapted to the fixed wiring terminal 601 is opened on the fixed tube 10, and a first conversion terminal 602 and a second conversion terminal 603 are fixedly connected to the connecting tube 6. 3, a first connection end 12 adapted to the first conversion end 602 is fixedly connected to the fixed cylinder 10, and the first connection end 12 and the second connection end 13 adapted to the first conversion end 602 are centrally symmetrically distributed about the central axis of the fixed cylinder 10; when the first connection end 12 and the second conversion end 603 are adapted to abut, the fixed wiring terminal 601, the first connection end 12 and the second conversion end 603 are electrically connected; when the second connection end 13 and the first conversion end 602 are adapted to abut, the fixed wiring terminal 601, the second connection end 13 and the first conversion end 602 are electrically connected.

[0026] In this embodiment, the surface of the connecting tube 6 is provided with an insulating layer, and the first conversion end 602 and the second conversion end 603 are made of conductive materials. When the first connection end 12 and the second conversion end 603 are adapted and abutted, the first connection end 12 and the second conversion end 603 are electrically connected to the fixed wiring terminal 601 through the connecting tube 6 to achieve the passage between the main power supply and the production equipment circuit, and the disconnection between the backup power supply and the production equipment circuit. When the second connection end 13 and the first conversion end 602 are adapted and abutted, the second connection end 13 and the first conversion end 602 are electrically connected to the fixed wiring terminal 601 through the connecting tube 6 to achieve the passage between the backup power supply and the production equipment circuit, and the disconnection between the main power supply and the production equipment circuit.

[0027] Specifically, Figure 2 As shown, the first connection terminal 12 is electrically connected to a main power supply, the second connection terminal 13 is electrically connected to a backup power supply, and the fixed connection terminal 601 is electrically connected to a production equipment circuit.

[0028] In this embodiment, the use of the first connection terminal 12 and the second connection terminal 13 is switched to achieve the switching of the main power supply and the backup power supply, so as to ensure that when the main power supply fails, the backup power supply is started in time to ensure the normal production work.

[0029] Specifically, Figure 1-3 As shown, a mounting tube 2 coaxially arranged with the slide rod 5 is provided on the base 1 , and two groups of winding parts 203 for winding the limiting rope 4 are fixedly connected to the top of the mounting tube 2 .

[0030] In this embodiment, the combination setting of the limiting rope 4 and the winding part 203 is to facilitate manual operation to fix the connecting tube 6 when the second magnet 9 is not powered on, so that the first connecting end 12 and the second conversion end 603 are adapted to abut against each other, thereby maintaining the electrical connection between the fixed terminal 601, the first connecting end 12 and the second conversion end 603.

[0031] Specifically, Figure 1 and Figure 3 As shown, the installation tube 2 is provided with two groups of second installation openings 202 , the second installation openings 202 are used for wiring the first connection ends 12 and the second connection ends 13 , and the installation tube 2 is provided with a first installation opening 201 adapted to the moving path of the fixed wiring terminal 601 .

[0032] In this embodiment, the second installation opening 202 is provided to facilitate the connection of the first connection terminal 12 and the second connection terminal 13 , and the first installation opening 201 is provided to facilitate the sliding adjustment of the fixed connection terminal 601 with the connecting tube 6 .

[0033] Specifically, Figure 4-9 As shown, the top of the connecting tube 6 is sequentially arranged with a fixing seat 7, a first magnet 8, a second magnet 9, and a mounting seat 3 along the central axis of the connecting tube 6. The top of the connecting tube 6 is fixedly connected with the fixing seat 7, and the first magnet 8 is mounted on the fixing seat 7. The second magnet 9 is specifically a power-on magnet, which is powered by the main power supply. When the main power supply is working, the second magnet 9 is powered on to absorb the first magnet 8, so that the first connection end 12 is stably abutted with the second conversion end 603. When the second magnet 9 is not connected to the main power supply, the first magnet 8 is abutted with the second magnet 9 by pulling the limit rope 4.

[0034] In this embodiment, when the main power supply is working, the second magnet 9 is powered on to attract the first magnet 8, so that the first connection end 12 and the second conversion end 603 are stably abutted to maintain a continuous path between the main power supply and the production equipment circuit. When the main power supply is powered off, the second magnet 9 loses its adsorption capacity, causing the first magnet 8 to separate from the second magnet 9, and the connecting tube 6 slides down along the slide bar 5. When the bottom of the connecting tube 6 contacts the base 1, the second connection end 13 and the first conversion end 602 are adapted to abut, thereby realizing a continuous path between the backup power supply and the production equipment circuit.

[0035] Specifically, Figure 4-9 As shown, two groups of wire-passing openings 302 are opened on the mounting seat 3, and two groups of limiting ropes 4 are fixedly connected to the fixing seat 7, and the two groups of limiting ropes 4 pass through the two groups of wire-passing openings 302 in a one-to-one correspondence.

[0036] In this embodiment, the setting of the wire opening 302 is to facilitate the movement and adjustment of the limiting rope 4 and to ensure the stability of the adjustment.

[0037] Specifically, Figure 4-9 As shown, a mounting portion 301 is fixedly connected to the top of the mounting seat 3 , and the mounting seat 3 is fixedly limited by the mounting portion 301 so that the mounting seat 3 and the mounting tube 2 remain relatively still.

[0038] In this embodiment, the setting of the mounting seat 3 and the mounting portion 301 ensures the stability of the connection, thereby facilitating the automatic conversion of the entire control switch.

[0039] During the specific working process of the dual power automatic switching switch of this embodiment, when the first magnet 8 and the second magnet 9 are abutted against each other, the first connection end 12 and the second conversion end 603 are stably abutted against each other, and the first connection end 12 and the second conversion end 603 are electrically connected to the fixed terminal 601 through the connecting tube 6 to realize the passage between the main power supply and the production equipment circuit, and the disconnection between the backup power supply and the production equipment circuit; when the first magnet 8 and the second magnet 9 are away from each other, the connecting tube 6 slides down along the sliding rod 5, and when the bottom of the connecting tube 6 contacts the base 1, the second connection end 13 and the first conversion end 602 are adapted to abut against each other, and the second connection end 13 and the first conversion end 602 are electrically connected to the fixed terminal 601 through the connecting tube 6 to realize the passage between the backup power supply and the production equipment circuit, the disconnection between the main power supply and the production equipment circuit, and the continuous formation of a passage between the backup power supply and the production equipment circuit.
