Description

Technical Field

[0001] The present application relates to the technical field of switches, and in particular to a dual power conversion switch. Background Art

[0002] A switch is an electronic component that opens a circuit, interrupts current or allows it to flow to other circuits. Switches are often used to turn a circuit on and off.

[0003] In the related art, the switch includes a housing, a power switch is arranged on the housing, a swing plate is rotatably connected to the power switch, and when the staff pulls the swing plate, the swing plate drives the power switch to realize the on and off of the circuit.

[0004] There may be problems with the power supply, causing the circuit to be disconnected. In some occasions where the power cannot be cut off, such as hospitals, special chemical equipment, etc., if the power is cut off, it will cause extremely serious consequences. Therefore, a switch is needed to keep the circuit running normally. Summary of the invention

[0005] In order to ensure that the circuit can operate normally when a power problem occurs, the present application provides a dual power conversion switch.

[0006] The present application provides a dual power conversion switch, which adopts the following technical solution:

[0007] A dual power conversion switch comprises a shell, wherein two power switches are arranged on the shell, a swing plate is rotatably connected to the power switches, a circuit board for electrically connecting the two power switches is arranged on the shell, an electric drive source is arranged on the circuit board, a rotating block is arranged on the electric drive source, a through hole is provided on the shell for the rotating block to pass through, two movable grooves are provided on the rotating block, and a movable block for inserting into the movable grooves is provided on the swing plate; when a problem occurs with the power switch, the circuit board drives the rotating block to rotate through the electric drive source, and the rotating block drives the swing plate to rotate through the movable block.

[0008] By adopting the above technical solution, if a power supply has a problem and the power switch is powered off, the circuit board can control the electric drive source to rotate, so that the electric drive source drives the rotating block to rotate. Since the moving block is located in the moving groove, the groove wall of the moving groove limits the moving block, so that the rotating block can stably drive the swing plate to rotate, so that one swing plate starts a power switch and the other swing plate turns off the other power switch, thereby switching the circuit and allowing the circuit to remain connected, avoiding the situation where the circuit is disconnected for a long time, so that the circuit can be stably in the power-on state; by passing the rotating block through the through hole, the staff can manually drive the rotating block to rotate, so that the rotating block can rotate stably, so that the staff can switch the power switch.

[0009] Optionally, an operating block is rotatably connected to the shell, a limit bar is slidably connected to the operating block, a limit groove for inserting the limit bar is provided on the rotating block, a sliding groove is provided in the through hole, a sliding inclined surface is provided in the sliding groove, and the distance between the sliding inclined surface and the operating block gradually decreases along the direction from the operating block to the electric drive source.

[0010] By adopting the above technical solution, the limit bar is connected by sliding on the operating block, so that the limit bar moves along the sliding inclined surface. Since the distance between the sliding inclined surface and the operating block gradually decreases along the direction from the operating block to the electric drive source, the limit bar can be smoothly inserted into the limit groove. The groove wall of the limit groove limits the limit bar, so that the limit bar and the rotating block are fixed to each other, so that the operating block and the rotating block can be fixed to each other, so that the staff can manually switch the power switch; if the limit bar does not abut the sliding inclined surface, the limit bar is not inserted into the limit groove at this time, so that the operating block and the rotating block are not fixed to each other, so that it is difficult for outsiders to drive the rotating block to rotate, that is, when an outsider accidentally touches the operating block, the power switch will not be switched, thereby reducing the situation where the circuit has problems due to the outsider accidentally touching the operating block.

[0011] Optionally, an operating bar is provided on the operating block, an operating ring is rotatably connected to the shell, an operating ring is provided on the operating ring, and the operating spring drives the operating bar to move in a direction away from the electric drive source.

[0012] By adopting the above technical solution, the operating spring drives the operating bar to move in a direction away from the electric drive source, so that the limit bar can slide in the limit groove. At this time, the limit bar is not limited by the sliding inclined surface, so that the limit bar can be separated from the limit groove, thereby making the operating block and the rotating block not fixed, so that the operating block can limit the rotating block to prevent accidental touch.

[0013] Optionally, a stop block is provided on the operating block, a first stop groove and a second stop groove are provided on the shell, the first stop groove is provided with a stop hole connected to the second stop groove, and the first stop groove, the second stop groove and the stop hole are all for inserting the stop block; when the stop block is located in the stop hole, the sliding inclined surface is located on the moving path of the limit bar; when the stop block is located in the first stop groove or the second stop groove, the power switch is started.

[0014] By adopting the above technical solution, the stop block slides from the first stop groove into the stop hole. At this time, the sliding slope is located on the moving path of the limit bar, so that the limit bar is inserted into the limit groove, so that the operating block and the rotating block are fixed to each other, so that the staff rotates the operating block to allow the stop block to move in the stop hole, so that the rotating block can stably turn on and off the power switch, and finally the stop block disengages from the stop hole from the second stop groove, so that the operating block and the rotating block are no longer fixed to each other; the stop block slides in the first stop groove or the second stop groove, so that the sliding slope is located on the moving path of the limit bar, so that the staff can quickly position the limit bar and reduce the difficulty of operation for the staff.

[0015] Optionally, a mounting cover is provided on the shell, and two fixing blocks are provided on the mounting cover. When the mounting cover is installed on the shell, each fixing block is located in the first retaining groove and the second retaining groove respectively.

[0016] By adopting the above technical solution, the fixing block is located in the first stop groove and the second stop groove, so that the installation cover can limit the insertion of the stop block into the first stop groove or the second stop groove, making it difficult for outsiders to move the stop block into the first stop groove or the second stop groove, thereby reducing the possibility of outsiders driving the power switch to switch.

[0017] Optionally, a first magnet is slidably connected to the mounting cover, two second magnets are slidably connected to the shell, and a fixing groove for inserting the second magnet is provided on the fixing block. When the mounting cover is installed on the shell, the first magnet attracts the second magnet, and the second magnet passes through the fixing groove.

[0018] By adopting the above technical solution, when the mounting cover is installed on the shell, the first magnet is slid to allow the first magnet to absorb the second magnet and move it, so that the second magnet is inserted into the fixing groove, so that the second magnet can stably limit the fixing block, so that the mounting cover can be stably installed on the shell.

[0019] Optionally, the shell is provided with a through hole for taking out the rotating block, the through hole is provided with a fixed cover, the through hole is provided on the fixed cover, the fixed cover is slidably connected with a mounting bar, the shell is provided with a mounting groove for inserting the mounting bar, and when the mounting bar is inserted into the mounting groove, the fixed cover blocks the through hole.

[0020] By adopting the above technical solution, because the rotating block drives the moving block multiple times, the rotating block will be damaged, so the staff needs to replace the rotating block. The rotating block can be taken out from the through hole, and the staff only needs to remove the fixed cover to replace the rotating block, which greatly reduces the difficulty of replacement for the staff; by inserting the mounting bar into the mounting groove, the groove wall of the mounting groove limits the mounting bar, so that the fixed cover can stably block the through hole to prevent the rotating block from detaching from the through hole.

[0021] Optionally, the fixed cover is provided with a first receiving groove for inserting the stop block, the first receiving groove is provided with a second receiving groove, and the fixed cover is provided with a receiving assembly. When the stop block is located in the second receiving groove, the stop block drives the mounting bar to detach from the mounting groove through the receiving assembly.

[0022] By adopting the above technical solution, the stop block is inserted into the first accommodating groove, and the stop block drives the mounting bar to move through the accommodating assembly, so that the mounting bar is disengaged from the mounting groove, thereby allowing the mounting bar to release the lock on the fixed cover, and the fixed cover can be removed from the through hole to facilitate the subsequent replacement of the rotating block.

[0023] Optionally, the accommodating component includes an accommodating bar, which is located on the sliding path of the second accommodating groove. The accommodating bar is provided with an inclined surface. When the accommodating bar is located on the rotation path of the operating bar, the distance between the inclined surface and the operating bar gradually increases along the direction from the rotating block to the electric drive source. The mounting bar is provided with a accommodating hole for inserting the accommodating bar, and the hole wall of the accommodating hole is provided with an accommodating inclined surface. The distance between the accommodating inclined surface and the stop block gradually increases along the direction from the accommodating bar to the bottom wall of the accommodating groove, and the accommodating inclined surface is located in the insertion path of the accommodating bar.

[0024] By adopting the above technical solution, the accommodating bar is located on the sliding path of the second accommodating groove, and the distance between the inclined surface and the operating bar gradually increases along the direction from the rotating block to the electric drive source, so that the accommodating bar drives the installation bar to move through the inclined surface, and the accommodating bar is inserted into the accommodating hole. Since the distance between the accommodating inclined surface and the stop block gradually increases along the direction from the accommodating bar to the bottom wall of the accommodating groove, and the accommodating inclined surface is located in the insertion path of the accommodating bar, the accommodating bar can drive the installation bar to move along the direction of the accommodating inclined surface, thereby allowing the installation bar to detach from the installation groove.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. If a power supply has a problem and the power switch is powered off, the circuit board can control the electric drive source to rotate, so that the electric drive source drives the rotating block to rotate. Since the moving block is located in the moving groove, the groove wall of the moving groove limits the moving block, so that the rotating block can stably drive the swing plate to rotate, so that one swing plate starts a power switch and the other swing plate turns off the other power switch, so as to switch the circuit and keep the circuit connected to avoid long-term disconnection of the circuit, so that the circuit can be stably powered on; by passing the rotating block through the perforation, the staff can manually drive the rotating block to rotate, so that the rotating block can rotate stably, so that the staff can switch the power switch.

[0027] 2. Connect the limit bar by sliding on the operating block, and let the limit bar move along the sliding inclined surface. Since the distance between the sliding inclined surface and the operating block gradually decreases along the direction from the operating block to the electric drive source, the limit bar can be smoothly inserted into the limit groove. The groove wall of the limit groove limits the limit bar, so that the limit bar and the rotating block are fixed to each other, so that the operating block and the rotating block can be fixed to each other, so that the staff can manually switch the power switch; if the limit bar does not abut the sliding inclined surface, the limit bar is not inserted into the limit groove at this time, so that the operating block and the rotating block are not fixed to each other, making it difficult for outsiders to drive the rotating block to rotate, that is, when an outsider accidentally touches the operating block, the power switch will not be switched, reducing the situation where the circuit has problems due to outsiders accidentally touching the operating block.
