Description

Technical Field

[0001] The utility model relates to the technical field of dual power conversion switch equipment, in particular to a dual power conversion switch. Background Art

[0002] To ensure the power supply safety of electrical equipment, a dual power transfer switch device is often required. The utility model patent application number CN202020842986.8 discloses a manual dual power transfer switch. The terminals and contacts of the first and second power supplies are placed in a housing of the same volume as the MCB in the prior art. The resulting manual dual power transfer switch (MTS) has the same volume as the MCB, that is, its width is less than half of that of the prior art product, while retaining the same other dimensions and features. This allows the MTS to be installed in accordance with the DIN standard with standard products such as the MCB, and presents its small size advantage, meeting market demand and making it more competitive. According to the disclosed technical solution, when using the existing dual power transfer switch device, on the one hand, the handle is easily deflected by foreign objects or human touch, which is not conducive to ensuring the stability of the power supply of the dual power transfer switch. On the other hand, during use, the power ring is easily misaligned due to human error, and it is impossible to effectively provide personnel with prompts. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a dual power conversion switch to solve the problems raised in the above background technology. The present invention can prevent the handle from rotating due to accidental contact by foreign objects or people, and can also prevent people from making mistakes in adjusting the conversion power source.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dual power conversion switch, comprising a dual power conversion switch body and a turning handle, a sliding assembly installed on the turning handle, the sliding assembly comprising a sliding groove and a guide rod, a clamping assembly installed on the guide rod, the clamping assembly comprising a connecting block and a spring 1, a limit assembly installed on the inner side of the dual power conversion switch body, the limit assembly comprising a clamping groove and a spring 2, an electric control assembly installed on the inner side of the clamping groove, the electric control assembly comprising an electrode and a piston, a connecting assembly installed on the inner side of the dual power conversion switch body, the connecting assembly comprising an air hole and a one-way valve.

[0005] Furthermore, the turning handle is installed on the outer side of the dual power conversion switch body, and the sliding groove is opened on the inner side of the turning handle.

[0006] Furthermore, the connecting block is clamped on the outer side of the turning handle, one end of the guide rod is integrally formed on the connecting block, and the other end of the guide rod passes through the sliding groove and extends to the inner side of the clamping groove.

[0007] Furthermore, the slot is provided on the inner side of the dual power conversion switch body, and the connecting block is connected to the inner wall of the slot via a spring.

[0008] Furthermore, the outer side of the piston is clamped on the inner wall of the clamping groove, and the bottom of the piston is connected to the inner wall of the clamping groove through a second spring.

[0009] Furthermore, the electrodes are mounted on the inner walls on both sides of the slot, the piston is a metal piston, and electric bells are mounted on both sides of the dual power conversion switch body via bolts.

[0010] Furthermore, the air hole is opened on the inner side of the dual power conversion switch body, and the one-way valve is installed on the inner side of the air hole.

[0011] Furthermore, the bottom of the card slot is in one-way communication with the outside of the dual power conversion switch body 1 through an air hole and a one-way valve, and the electrode is connected to the electric bell through an electric wire.

[0012] Beneficial effects: 1. When the dual power conversion switch is in use, when adjusting the power supply of the electrical equipment, it is necessary to first pull the connecting block outward on the outside of the turning handle. The connecting block stretches the spring and drives the guide rod to move outward from the inside of the card slot, thereby separating the guide rod from the card slot, and the turning handle can be rotated. When the turning handle is rotated to the desired position, the spring pulls the connecting block, and the connecting block drives the guide rod to be inserted into the inside of the card slot to fix the turning handle, thereby preventing the turning handle from rotating due to accidental contact with foreign objects or people, thereby ensuring the stability of power supply to the electrical equipment.

[0013] 2. When the dual power transfer switch is in use, when switching the power supply of the power-off electrical equipment, the connecting block is pulled outward, so that the guide rod is moved out from the inner side of the slot, thereby pushing the second spring and the piston outward, and the piston contacts the electrode. If the dual power transfer switch body is not operated by the personnel, the side will cause the doorbell to be turned on, thereby avoiding the situation where the personnel make the wrong adjustment to switch the power supply body, and effectively preventing the normal operation of other equipment from being affected by the personnel's mistake.

[0014] 3. The dual power transfer switch is reasonably designed, efficient and convenient to use, and is suitable for providing stable power supply for electrical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

During use, when adjusting the power supply of the electrical equipment, it is necessary to first pull the connecting block 6 outward on the outside of the turning handle 2, and the connecting block 6 stretches the spring 17 and drives the guide rod 5 to move outward from the inner side of the card slot 3, thereby separating the guide rod 5 from the card slot 3, and the turning handle 2 can be rotated. When the turning handle 2 is rotated to the desired position, the spring 17 pulls the connecting block 6, and the connecting block 6 drives the guide rod 5 to be inserted into the inner side of the card slot 3, fixing the turning handle 2, preventing the turning handle 2 from rotating due to accidental contact with foreign objects or people, and ensuring the stability of power supply to the electrical equipment.

[0021] In this embodiment, the connecting block 6 is stuck on the outer side of the handle 2, one end of the guide rod 5 is integrally formed on the connecting block 6, the other end of the guide rod 5 passes through the slide groove 4 and extends to the inner side of the slot 3, the slot 3 is opened on the inner side of the dual power conversion switch body 1, the connecting block 6 is connected to the inner wall of the slide groove 4 through a spring 1 7, the outer side of the piston 8 is stuck on the inner wall of the slot 3, the bottom of the piston 8 is connected to the inner wall of the slot 3 through a spring 2 9, the electrode 10 is installed on the inner wall of the slot 3 on both sides, the piston 8 is a metal piston, and an electric bell 13 is installed on both sides of the dual power conversion switch body 1 by bolts.
