Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] like Figures 1 to 4As shown, a panel of this utility model includes a panel body 1, an inner connecting component 2, and an outer connecting component 3. The front of the panel body 1 is provided with a first rotating groove 11. The inner connecting component 2 includes a rotating block 21 and an inner magnetic block 22. The rotating block 21 is rotatably disposed on the back of the panel body 1. The inner magnetic block 22 is disposed on the rotating block 21 and has a first inner magnetic part 221 and a second inner magnetic part 222. The first inner magnetic part 221 and the second inner magnetic part 222 are arranged sequentially along a direction perpendicular to a first direction. The outer connecting component 3 includes a knob 31, an outer magnetic block 32, and multiple balls 33. The outer magnetic block 32 is disposed on the knob 31. A knob 31 is disposed on the front side of the panel body 1 at intervals. The knob 31 and / or the outer magnetic block 32 are provided with a second rotating groove 34 corresponding to the first rotating groove 11. A plurality of balls 33 are disposed between the first rotating groove 11 and the second rotating groove 34. The two sides of the balls 33 are respectively rotatably connected to the first rotating groove 11 and the second rotating groove 34. The outer magnetic block 32 is provided with a first outer magnetic part 321 and a second outer magnetic part 322. The first outer magnetic part 321 is disposed corresponding to the first inner magnetic part 221 and is magnetically connected to the first inner magnetic part 221. The second outer magnetic part 322 is disposed corresponding to the second inner magnetic part 222 and is magnetically connected to the second inner magnetic part 222.

[0030] In the above technical solution, the back of the panel of this utility model is provided with an inner connecting component 2 and the front is provided with an outer connecting component 3. In the inner connecting component 2, a rotating block 21 is used to connect a controlled component 4 that needs to be adjusted or switched by rotation. An inner magnetic block 22 is disposed on the rotating block 21, and the rotating block 21 is rotatably connected to the panel body 1. The first inner magnetic part 221 and the second inner magnetic part 222 of the inner magnetic block 22 are arranged sequentially along a direction perpendicular to the first direction. When the rotating block 21 rotates... When activated, it drives the controlled component 4 to rotate together, thereby adjusting or switching the function; in the external connection component 3, multiple balls 33 are provided between the first rotating groove 11 of the panel body 1 and the second rotating groove 34 of the knob 31, so that the knob 31 can rotate along the second rotating groove 34. Furthermore, an external magnetic block 32 is provided on the knob 31, and the first external magnetic part 321 and the second external magnetic part 322 of the external magnetic block 32 are respectively provided corresponding to the first internal magnetic part 221 and the second internal magnetic part 222, so that the first external magnetic part 321 can be magnetically attracted. The first inner magnetic part 221 and the second outer magnetic part 322 are magnetically connected to the second inner magnetic part 222. When the knob 31 rotates along the second rotating groove 34, the first outer magnetic part 321 attracts the first inner magnetic part 221 to rotate, and the second outer magnetic part 322 attracts the second inner magnetic part 222 to rotate, thereby causing the rotating block 21 to rotate, which in turn drives the controlled component 4 to rotate, thereby adjusting or switching the function. In summary, the knob 31 and the rotating component on the panel of this utility model are not connected by a hole through the panel body 1, but by magnetic force. Long-term use will not reduce the sealing performance of the panel, which can meet the high explosion-proof requirements. There is no high risk in areas with high explosion-proof requirements. In addition, the operator can remove the external connecting component 3 from the panel body 1 by applying a pulling force away from the panel body 1. Therefore, when the operator feels that the magnetic force when turning the knob 31 is too strong or too weak, the operator can easily replace the external connecting component 3 for convenient use.

[0031] In addition, the first inner magnetic part 221 and the second inner magnetic part 222 of the inner magnetic block 22 can be set close together or spaced apart; the first outer magnetic part 321 and the second outer magnetic part 322 of the outer magnetic block 32 can be set close together or spaced apart.

[0032] In addition, the structure of the inner connecting component 2 can be similar to that of the outer connecting component 3, or it can be connected to the panel body 1 by means of the rotating shaft 23 alone. In this case, the rotating shaft 23 and the rotating member are axially limited, and the rotating member and the rotating shaft 23 cannot move in the first direction. The rotating shaft 23 is rotatably connected to the panel body 1, or it can be rotatably connected to the rotating member, or it can be rotatably connected to the panel body 1 and the rotating member.

[0033] Furthermore, the knob 31 has an outer receiving groove 311 on its back, and the outer magnetic block 32 is fixedly disposed in the outer receiving groove 311 to minimize the distance between the outer magnetic block 32 and the inner magnetic block 22, thereby enhancing the strength of the magnetic connection.

[0034] Furthermore, the external connection component 3 also includes a guide post 36. The front side of the panel body 1 is provided with a first post hole 12, which is located at the center of the first rotating groove 11. The external connection component 3 is provided with a second post hole 35 that passes through the knob 31 and / or the external magnetic block 32 along a first direction. The second post hole 35 is provided corresponding to the first post hole 12. The guide post 36 extends into the first post hole 12 and the second post hole 35 and is connected to the first post hole 12 and the second post hole 35.

[0035] In the above technical solution, the guide post 36 is used to ensure that the knob 31 rotates accurately, so as to achieve more precise adjustment and switching, and prevent it from deviating in a direction perpendicular to the first direction.

[0036] Furthermore, a limiting boss 37 is provided around one end of the first post hole 12 near the panel body 1. The guide post 36 includes a post head 361 and a post body 362 arranged sequentially from away from the panel body 1 to near the panel body 1. The post body 362 passes through the limiting boss 37, extends into the first post hole 12, and is connected to the first post hole 12. The side of the post head 361 near the panel body 1 is connected to the limiting boss 37.

[0037] In the above technical solution, the column 362 can be rotatably connected to the first column hole 12 and the second column hole 35, or it can be rotatably connected to only one of the first column hole 12 and the second column hole 35. When the column 362 is fixedly connected to the second column hole 35 and rotatably connected to the first column hole 12, the external connecting component 3 is more convenient to disassemble and assemble.

[0038] Furthermore, the two balls 33 are symmetrically arranged along the center of the first rotating groove 11 to ensure that the two sides of the knob 31 are balanced, so as to ensure that the knob 31 rotates accurately and prevent the distance between the two sides of the knob 31 and the panel body 1 from being different.

[0039] Furthermore, the knob 31 is provided with a first protrusion 312 and a second protrusion 313 on opposite sides perpendicular to the first direction, respectively. The first protrusion 312 protrudes a greater distance than the second protrusion 313, so as to facilitate the operator in identifying the direction of the knob 31. Furthermore, the front of the panel body 1 may be provided with a scale groove 13 surrounding the first rotation groove 11. Multiple markings are engraved on or inside the scale groove 13, so that when the operator turns the knob 31 to point the first protrusion 312 to the corresponding marking, the operator can know what state the corresponding equipment is adjusted or switched to.

[0040] Furthermore, the first protrusion 312 and the second protrusion 313 are respectively provided with the second rotating groove 34 on the side near the panel body 1; and / or, the positions of the outer magnetic block 32 corresponding to the first protrusion 312 and the second protrusion 313 are provided with the second rotating groove 34, so that the second rotating groove 34 is a multi-segment groove.

[0041] Furthermore, the second protrusion 313 has a rounded corner 314 at one end away from the panel body 1 and the first protrusion 312, so as to facilitate the operator to identify the direction of the knob 31 and improve the operating comfort.

[0042] Furthermore, the groove surfaces of the first rotating groove 11 and the second rotating groove 34 are both arc surfaces, and the diameter of the groove surfaces of the first rotating groove 11 and the second rotating groove 34 is not less than the diameter of the ball 33. Preferably, the diameter of the groove surfaces of the first rotating groove 11 and the second rotating groove 34 is equal to the diameter of the ball 33, so as to prevent the knob 31 from shifting in a direction perpendicular to the first direction.

[0043] This utility model also relates to a control box, including a box body and the aforementioned panel. An opening is provided on one side of the box body, and the panel body 1 is disposed on and sealed to the opening. The front of the panel body 1 faces outward, and the back of the panel body 1 faces inward into the box body.

[0044] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0045] Furthermore, rotatable connection and rotatable setting refer to the ability of two connected components to rotate, including but not limited to connections via bearings or clearance fits.

[0046] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0047] In summary, this utility model embodiment provides a panel and a control box, the technical effects of which are as follows:

[0048] The back of the panel of this utility model is provided with an inner connecting component 2, and the front is provided with an outer connecting component 3. In the inner connecting component 2, a rotating block 21 is used to connect a controlled component 4 that needs to be adjusted or switched by rotation. An inner magnetic block 22 is disposed on the rotating block 21, and the rotating block 21 is rotatably connected to the panel body 1. The first inner magnetic part 221 and the second inner magnetic part 222 of the inner magnetic block 22 are arranged sequentially along a direction perpendicular to the first direction. When the rotating block 21 rotates, it drives the controlled component 4... The control component 4 rotates together to adjust or switch the function; in the external connection component 3, multiple balls 33 are provided between the first rotating groove 11 of the panel body 1 and the second rotating groove 34 of the knob 31, so that the knob 31 can rotate along the second rotating groove 34. Furthermore, an external magnetic block 32 is provided on the knob 31, and the first external magnetic part 321 and the second external magnetic part 322 of the external magnetic block 32 are respectively provided corresponding to the first internal magnetic part 221 and the second internal magnetic part 222, so that the first external magnetic part 321 can be magnetically connected to the first internal magnetic part 221 and the second internal magnetic part 222. An inner magnetic part 221 and a second outer magnetic part 322 can be magnetically connected to the second inner magnetic part 222. When the knob 31 rotates along the second rotating groove 34, the first outer magnetic part 321 attracts the first inner magnetic part 221 to rotate, and the second outer magnetic part 322 attracts the second inner magnetic part 222 to rotate, thereby causing the rotating block 21 to rotate, which in turn drives the controlled component 4 to rotate, thereby adjusting or switching the function. In summary, the knob 31 and the rotating component on the panel of this utility model are not connected by a hole through the panel body 1, but by magnetic force. Long-term use will not reduce the sealing performance of the panel, which can meet high explosion-proof requirements and will not pose a high risk in areas with high explosion-proof requirements. In addition, the operator can remove the external connecting component 3 from the panel body 1 by applying a pulling force away from the panel body 1. Therefore, when the operator feels that the magnetic force when turning the knob 31 is too strong or too weak, the operator can easily replace the external connecting component 3 for convenient use.
