[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.
[0020] For ease of understanding, please refer to the attached Figures 1 to 3 , the specific structure and working principle of the electric crank disclosed in the present invention are explained in detail with reference to the embodiments.
[0021] The present disclosure relates to an electric crank, which is used to adjust a circuit breaker in a switch cabinet and can accurately stop driving the circuit breaker after the circuit breaker reaches a specified position, thereby preventing the circuit breaker or the electric crank from being damaged. Figure 1 and Figure 2The electric crank disclosed in the present invention includes a crank body 1, a first rotating member 2, a second rotating member 3 and a power member 4, wherein the crank body 1 has an inner cavity 11, the first rotating member 2 is connected to the inner cavity 11 by rotation relative to its own axis, and one end of the first rotating member 2 will also extend out of the inner cavity 11 to cooperate with the circuit breaker in the switch cabinet, so as to drive the circuit breaker to move through its own rotation, and a first magnetic member 21 is also provided on the first rotating member 2, and the second rotating member 3 is also connected to the inner cavity 11 by rotation relative to its own axis, and is coaxially arranged with the first rotating member 2, and a second magnetic member 31 is provided on the second rotating member 3. When the second rotating member 3 rotates, the first rotating member 2 can be driven to rotate along its own axis in the inner cavity 11 through the cooperation between the second magnetic member 31 and the first magnetic member 21, and the power member 4 can drive the second rotating member 3 to rotate along its own axis, thereby driving the first rotating member 2 to rotate, thereby completing the adjustment of the circuit breaker in the switch cabinet.
[0022] The electric crank of the present disclosure drives the second rotating member 3 to rotate along its own axis through the power member 4, and then drives the first magnetic member 21 on the first rotating member 2 to rotate through the second magnetic member 31 on the second rotating member 3, and finally drives the first rotating member 2 to rotate along its own axis through the first magnetic member 21 to complete the adjustment of the circuit breaker in the switch cabinet. During the entire adjustment process, the second rotating member 3 does not contact the first rotating member 2. When the circuit breaker reaches a suitable position, the first rotating member 2 can be stuck, so that the first rotating member 2 will not continue to rotate, and the second rotating member 3 will continue to rotate under the drive of the power member 4 and will not be stuck by the first rotating member 2. Therefore, even if the staff fails to find that the circuit breaker has reached a suitable position in time, it will not cause the power member 4 to be stuck or the circuit breaker to be damaged, thereby protecting the switch cabinet to a great extent and improving the adjustment efficiency of the circuit breaker.
[0023] In one embodiment of the present disclosure, see Figure 2 and Figure 3 , the first rotating member 2 is cylindrical, the second rotating member 3 is cylindrical and is sleeved outside the first rotating member 2, and the inner wall of the second rotating member 3 is spaced from the outer wall of the first rotating member 2. By setting the first rotating member 2 and the second rotating member 3 to be cylindrical and cylindrical, it is convenient for the second rotating member 3 to drive the first rotating member 2 to rotate, and the second rotating member 3 can be held without contacting the first rotating member 2 during the rotation. In order to adapt to the cylindrical and cylindrical first rotating member 2 and the second rotating member 3, in some embodiments of the present disclosure, see Figure 2 and Figure 3The first magnetic member 21 is annular and is located on the outer wall of the first rotating member 2. The second magnetic member 31 is also annular and is located on the outer wall of the second rotating member 3. It is arranged corresponding to the first magnetic member 21 to ensure that the second magnetic member 31 can rotate synchronously with the second rotating member 3, and can also ensure that the first magnetic member 21 can better receive the magnetic force of the second magnetic member 31, thereby better driving the first rotating member 2 to rotate.
[0024] Of course, in other embodiments, the first rotating member 2 and the second rotating member 3 may also be both cylindrical, and the end of the first rotating member 2 is in contact with the end of the second rotating member 3, and the first magnetic member 21 and the second magnetic member 31 are located at the end where the first rotating member 2 and the second rotating member 3 are in contact. When the power member 4 drives the second rotating member 3 to rotate, it can also synchronously drive the first rotating member 2 to rotate. Of course, in other embodiments, the shapes and connection methods of the first rotating member 2, the second rotating member 3, the first magnetic member 21 and the second magnetic member 31 may also be of other types, which can be determined according to actual conditions, and the present disclosure does not impose any restrictions on this.
[0025] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The electric crank is also provided with an alarm component 5, which will sound an alarm when the first rotating member 2 and the second rotating member 3 rotate out of sync. By providing the alarm component 5, when the electric crank is working, it is convenient for the staff to find out in time when the circuit breaker reaches a suitable position and the first rotating member 2 stops rotating, and turn off the power member 4, so as to avoid wasting time and reducing the adjustment efficiency of the circuit breaker. When the electric crank stops working, the alarm component 5 will also stop working to avoid continuous alarm.
[0026] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The alarm component 5 includes a laser sensor 51 and a reflector 52. The laser sensor 51 is connected to the first rotating member 2 or the second rotating member 3, and the reflector 52 is connected to the other one. The laser sensor 51 can send a signal and receive a laser signal reflected by the reflector 52.
[0027] When the first rotating member 2 and the second rotating member 3 rotate synchronously, the laser sensor 51 is aligned with the reflector 52. When the laser sensor 51 continues to receive the model reflected by the reflector 52, it can be determined that the first rotating member 2 and the second rotating member 3 are both rotating and the circuit breaker has not reached the specified position. When the laser sensor 51 periodically receives the laser signal, it can be determined that the first rotating member 2 is no longer rotating. At this time, an alarm will be issued to notify the staff to stop the power member 4.
[0028] If the first rotating member 2 and the second rotating member 3 rotate synchronously, and the laser sensor 51 is not aligned with the reflector 52, when the laser sensor 51 cannot receive the model reflected by the reflector 52, it can be determined that the first rotating member 2 and the second rotating member 3 are both rotating, and the circuit breaker has not reached the specified position. When the laser signal is received periodically, it can be determined that the first rotating member 2 is no longer rotating, and an alarm will be issued to notify the staff.
[0029] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The alarm component 5 is also provided with an alarm 53, which can send out an alarm when the laser sensor 51 receives a periodic laser signal to notify the staff that the circuit breaker has reached a suitable position and the power component 4 can be turned off. The alarm 53 can be a buzzer or a device that can emit light, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0030] In one embodiment of the present disclosure, see Figure 2 and Figure 3 , first bearings 22 are respectively provided at both ends of the first rotating member 2, the inner ring of the first bearing 22 is fixedly connected to the first rotating member 2, and the outer ring is fixedly connected in the inner cavity 11. By connecting the first rotating member 2 in the inner cavity 11 through the first bearing 22, the first bearing 22 can be used to have high transmission efficiency, low friction coefficient and easy maintenance, so that the first rotating member 2 can better drive the circuit breaker to move and facilitate maintenance. Of course, in other embodiments, the first rotating member 2 can also be rotatably connected in the inner cavity 11 in other ways, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0031] In one embodiment of the present disclosure, the first bearing 22 is an insulating bearing, and the first bearing 22 is set as an insulating bearing to prevent the current in the circuit breaker from flowing to the crank body 1 through the first rotating member 2, thereby causing damage to the staff holding the crank body 1. Of course, in other embodiments, the first rotating member 2, the second rotating member 3, etc. can also be made of insulating materials, so that the electric crank of the present disclosure is safer, which will not be repeated here.
[0032] In one embodiment of the present disclosure, see Figure 2 and Figure 3, second bearings 32 are respectively provided at both ends of the second rotating member 3, the inner ring of the second bearing 32 is fixedly connected to the second rotating member 3, and the outer ring is fixedly connected in the inner cavity 11. By connecting the second rotating member 3 in the inner cavity 11 through the second bearing 32, the characteristics of the first bearing 22 with high transmission efficiency, low friction coefficient and easy maintenance can be utilized, so that the second rotating member 3 can better drive the first rotating member 2 to rotate, and it is easy to maintain. Of course, in other embodiments, the second rotating member 3 can also be rotatably connected in the inner cavity 11 in other ways, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0033] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The power member 4 includes a motor 41 and a switch 42. The motor 41 is connected to the second rotating member 3 to drive the second rotating member 3 to rotate along its own axis. The switch 42 is used to control the opening or closing of the motor 41. The connection between the motor 41 and the second rotating member 3 can be directly connected or connected through a transmission member, such as a plurality of gears, or other connection methods known to those skilled in the art. The switch 42 can expose the crank body 1 so that the staff can control the opening or closing of the motor 41 through the switch 42.
[0034] When the electric crank of the present disclosure is used, the first rotating member 2 exposed from the crank body 1 needs to be matched with the circuit breaker, and then the motor 41 is started by the switch 42 to drive the second rotating member 3 to rotate, and the second rotating member 3 will drive the first rotating member 2 to rotate through the cooperation between the first magnetic member 21 and the second magnetic member 31, and the first rotating member 2 will drive the circuit breaker to move to a suitable position in the switch cabinet. When the circuit breaker is in a suitable position, the first rotating member 2 will not continue to rotate, and at this time the laser sensor 51 will receive the laser signal reflected by the periodic reflector 52, and then the alarm member 53 will sound an alarm to remind the staff that the circuit breaker has reached a suitable position, and the motor 41 can be turned off by the switch 42.
[0035] The electric crank of the present invention drives the first rotating member 2 to rotate through the cooperation between the first magnetic member 21 and the second magnetic member 31, thereby ensuring that the second rotating member 3 and the first rotating member 2 do not contact each other. Even if the first rotating member 2 does not continue to rotate after the circuit breaker reaches a suitable position, the second rotating member 3 will continue to rotate driven by the power member 4 and will not be stuck by the first rotating member 2. Therefore, even if the staff fails to find that the circuit breaker has reached a suitable position in time, the power member 4 will not be stuck or the circuit breaker will not be damaged, thereby protecting the switch cabinet to a great extent and improving the adjustment efficiency of the circuit breaker.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0038] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
