DETAILED DESCRIPTION

[0029] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the advantages and features of the present invention easier for those skilled in the art to understand. Obviously, the embodiments described in this application are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0030] See also Figure 1 、 Figure 2 and Figure 4 An electric control cabinet operating device is shown, which includes a mounting base 1 and a cover plate 2 fixed to one side of the mounting base 1 along a first direction. A receiving chamber 10 is formed between the mounting base 1 and the cover plate 2, and the cover plate 2 is provided with an opening 21 communicating with the receiving chamber 10. The operating device also includes a connecting shaft 3 and a locking member 4, wherein the connecting shaft 3 is movably arranged along the first direction, and has a connecting end 311 that can extend from the opening 21 into the receiving chamber 10, and the connecting end 311 is provided with a first limiting structure. The locking member 4 is movably arranged in the receiving chamber 10 along the second direction, and has a first position and a second position. The locking member 4 has a second limiting structure. When the locking member 4 is in the first position, the first limiting structure can be limited by the second limiting structure and is located on the side of the locking member 4 away from the cover plate 2, so that the connecting shaft 3 and the mounting base 1 are connected to each other. The locking member 4 is provided with a first through hole 41 through which the first limiting structure can pass when in the second position. When the locking member 4 is in the second position, the connecting end 311 can pass through the locking member 4 through the first through hole 41 and disengage from the accommodating cavity 10 from the opening 21, thereby separating the connecting shaft 3 from the mounting seat 1.

[0031] In this embodiment, one of the mounting base 1 and the locking member 4 is fixedly provided with a guide member, and the other is provided with a guide slot 42 extending along the second direction. The guide member is slidably inserted into the guide slot 42. The cooperation between the guide member and the guide slot 42 provides better positioning of the locking member 4, prevents the locking member 4 from shaking, and improves the stability of the operating device. At the same time, it also provides guidance for the movement of the locking member 4, improving the stability of the state transition of the locking member 4.

[0032] In this embodiment, see Figure 8 As shown, the connecting shaft 3 includes a shaft body 31 extending along a first direction, one end of the shaft body 31 forms a connecting end 311, and the first limiting structure is a limiting pin 32 fixed to the connecting end 311, and the length extension direction of the limiting pin 32 is perpendicular to the first direction. Figure 9 、 Figure 10As shown, the second limiting structure is the side of the locking member 4 facing away from the cover plate 2. When the locking member 4 is in the first position, the limiting pin 32 and the side of the locking member 4 abut against each other, thereby limiting the connection end 311 from disengaging from the accommodating cavity 10 along the first direction. When the locking member 4 is in the second position, the limiting pin 32 corresponds to the position of the first through hole 41, so that it can pass through the locking member 4 and can disengage from the accommodating cavity from the opening 21.

[0033] In this embodiment, an elastic member (not shown in the figure) is provided between the locking member 4 and the mounting seat 1 for driving the locking member 4 to move toward the first position, so that in the absence of external force, the locking member 4 can be maintained in the first position and keep the connection shaft 3 limited. At the same time, after the external force is removed, the locking member 4 can also automatically switch to the first position under the drive of the elastic member.

[0034] In this embodiment, a first inclined surface 411 is provided on the side of the locking member 4 facing the cover plate 2. The first inclined surface 411 is located on one side of the first through hole 41 along the second direction and is located behind the second retaining structure. The first inclined surface 411 extends away from the cover plate 2 in the first direction and extends obliquely toward the first through hole 41 along the second direction. When the locking member 4 is in the first position, the first inclined surface 411 is located along the path of the connecting end 311 inserted into the accommodating cavity 10 along the first direction. As the connecting end 311 moves along the first direction during insertion into the accommodating cavity 10, the first inclined surface 411 can slide in conjunction with the connecting end 311. In this embodiment, the first inclined surface 411 can slide in conjunction with the retaining pin 32, thereby driving the locking member 4 to the second position. This allows the connecting end 311 to pass through the first through hole 41 and extend to the other side of the locking member 4 without requiring the locking member 4 to be repositioned, simplifying operation.

[0035] In this embodiment, the operating device includes a handle 5 having an operating portion 51 and a connecting portion. The connecting portion extends along a first direction and is rotatably connected to the mounting base 1 about a rotational centerline extending along the first direction. Specifically, the axis of the connecting portion extends colinearly with the rotational centerline. The operating portion 51 is fixedly mounted on a side of the connecting portion away from the mounting base 1. Rotating the operating portion 51 can drive the connecting portion to rotate about the rotational centerline.

[0036] In this embodiment, the mounting base 1 is provided with an insertion hole 11, and at least part of the connecting portion extends from the insertion hole 11 into the accommodating cavity 10. The connecting portion is further provided with a third limiting structure 531, and the third limiting structure 531 is located in the accommodating cavity 10. The mounting base 1 is provided with a limiting protrusion 12, and the limiting protrusion 12 is located on the path of the third limiting structure 531 rotating around the rotation center line. Specifically, see Figure 3As shown, the connecting portion includes an inserting member 52 and a fixing member 53 that are fixedly connected. Part of the inserting member 52 extends from the insertion hole 11 into the accommodating cavity 10. The fixing member 53 is located in the accommodating cavity 10. The third limiting structure 531 is fixed on the fixing member 53. Figure 7 As shown, in this embodiment, the fixing member 53 is in the shape of a circular plate. The projected area of ​​the fixing member 53 along the first direction is larger than the projected area of ​​the insertion hole 11. The mounting seat 1 is clamped between the inserting member 52 and the fixing member 53. The third limiting structure 531 protrudes outward from the outer side of the fixing member 53 in the radial direction of the fixing member 53. The limiting protrusion 12 is fixed to the circumferential outer side of the fixing member 53. The cooperation between the third limiting structure 531 and the limiting protrusion 12 limits the rotation of the handle 5.

[0037] In this embodiment, see Figure 6 As shown, the limiting protrusion 12 constitutes the aforementioned guide member, and the locking member 4 is provided with a guide groove 42, in which the limiting protrusion 12 is slidably inserted. While limiting the rotation of the handle 5, the limiting protrusion 12 also serves to position and guide the locking member 4, making the structure of the operating device simpler.

[0038] In this embodiment, the handle 5 has a first state and a second state. The handle 5 switches between the first state and the second state during rotation about the rotation centerline. The limiting protrusions 12 include two spaced apart protrusions. When the handle 5 is in the first state, the third limiting structure 531 abuts against one limiting protrusion 12. When the handle 5 is in the second state, the third limiting structure 531 abuts against the other limiting protrusion 12. The cooperation between the two limiting protrusions 12 and the third limiting structure 531 enables the operator to more accurately achieve state transitions, and also limits the rotation angle of the handle 5, thereby preventing the handle 5 from rotating beyond the range.

[0039] In this embodiment, see Figure 6 As shown, the locking member 4 is provided with two guide grooves 42, and the two limiting protrusions 12 are respectively inserted into the two guide grooves 42. Through the cooperation of the two pairs of limiting protrusions 12 and the guide grooves 42, the positioning accuracy of the locking member 4, and the movement accuracy and stability of the locking member 4 are further improved. Specifically, along the second direction, the two guide grooves 42 are provided on different sides of the first through hole 41; and along the third direction, the two guide grooves 42 are provided on different sides of the first through hole 41, and the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. The two guide grooves 42 are distributed on both sides of the first through hole 41, which also improves accuracy and stability, and can also play a fool-proof role to avoid incorrect installation of the locking member 4.

[0040] In this embodiment, the connecting portion is provided with a slot 521 for the connecting end 311 to be inserted, the slot 521 is connected to the accommodating cavity 10, and a radial limiting structure is provided between the slot 521 and the connecting end 311 to limit the relative rotation between the two. Therefore, when the connecting end 311 is inserted into the slot 521, the connecting shaft 3 can be driven to rotate together by rotating the handle 5. Figure 3 As shown, the inserting member 52 is provided with a slot 521 extending along the first direction, and the fixing member 53 is provided with a third through hole 532 for the connecting end 311 to be inserted into the slot 521. In this embodiment, the slot 521 and the third through hole 532 have the same cross-sectional shape.

[0041] In this embodiment, see Figure 5 As shown, the radial limiting structure includes a limiting pin 32 disposed at the connecting end 311. The limiting pin 32 cooperates with the wall of the slot 521 to achieve positional limitation between the connecting shaft 3 and the handle 5. In some embodiments, radial limiting can be achieved by adapting the cross-sectional shape of the connecting shaft 3 to the shape of the slot 521. In this embodiment, the connecting shaft 3 has a locked state and an unlocked state. When the handle 5 is in the first state, the connecting shaft 3 is in the locked state; when the handle 5 is in the second state, the connecting shaft 3 is in the unlocked state.

[0042] In this embodiment, see Figure 5 As shown, when the handle 5 is in the first state and the locking member 4 is in the first position, the connecting end 311 is restricted by the locking member 4 and is located on the side away from the cover plate 2. At the same time, the connecting end 311 is cooperatively inserted into the slot 521. In this state, the connecting shaft 3 and the handle 5 are connected to each other. The locking member 4 is provided with a second through hole 43 through which the first limiting structure can pass when the locking member 4 is in the first position and the connecting shaft 3 is in the unlocked state. By rotating the handle 5 to drive the connecting shaft 3 to rotate, when the connecting shaft 3 is converted to the unlocked state, even if the locking member 4 is in the first position, the connecting end 311 can still pass through the second through hole 43 and detach from the accommodating cavity 10 through the opening 21, thereby separating from the mounting base 1 and the handle 5.

[0043] In this embodiment, see Figure 9 、 Figure 10 As shown, the extension direction of the first through hole 41 forms a certain angle with the extension direction of the second through hole 43. Specifically, the handle 5 rotates 90° around the rotation centerline to switch between the first state and the second state, and the connecting shaft 3 also rotates 90° around its own axis to switch between the locked state and the unlocked state. The extension direction of the first through hole 41 forms a right angle with the extension direction of the second through hole 43.

[0044] The operating device of this embodiment has a mounting base 1 and a cover plate 2 fixed on the door of the electric control cabinet, and the end of the connecting shaft 3 located at the opposite end of the connecting end 311 is connected to the cabinet body. By rotating the connecting shaft 3, the opening and closing of the electric control cabinet can be controlled, and the locking and unlocking of the cabinet door and the cabinet body can also be achieved through the operating device. Specifically, when the handle 5 is in the first state, the locking member 4 is in the first position, and the connecting end 311 is located in the slot 521 of the handle 5, the electric control cabinet is in the closing state, and the cabinet door and the cabinet body are locked, and the cabinet door cannot be opened to ensure safety. By rotating the handle 5 to convert it to the second state, during this process, the connecting shaft 3 also rotates and converts to the unlocking state, and the connecting shaft 3 drives the electric control cabinet to convert to the opening state, the circuit is disconnected, and at the same time, the connecting end 311 can also pass through the second through hole 43, and the cabinet door can also be opened.

[0045] In this embodiment, when the handle 5 is in the first state and the connecting shaft 3 is in the locked state, the connection between the connecting shaft 3 and the handle 5 can be unlocked by driving the locking member 4 to switch to the second position, thereby releasing the lock between the cabinet door and the cabinet body, and thus opening the cabinet door. Specifically, the mounting base 1 is provided with a second through-hole 16 extending along the second direction, and the locking member 4 has a driving rod 45 for driving itself to switch between the first position and the second position. The driving rod 45 extends along the second direction and is inserted into the second through-hole 16. By pushing the driving rod 45, the locking member 4 can be driven to switch to the second position. In this embodiment, an annular groove 451 is provided on the circumferential outer side of the driving rod 45, and a first sealing ring 46 is clamped in the annular groove 451. The first sealing ring 46 is used to achieve a seal between the driving rod 45 and the mounting base 1, thereby achieving a waterproof function.

[0046] In this embodiment, the operating device includes a locking pin 6 movably arranged on the handle 5 along a first direction, the mounting base 1 is provided with a first through-hole 13, and the locking member 4 is provided with a locking hole 44. The operating handle has an anti-accidental touch mode. In the anti-accidental touch mode, the handle 5 is in the second state, the locking member 4 is in the second position, the projections of the locking pin 6, the first through-hole 13, and the locking hole 44 along the first direction coincide with each other, and the locking pin 6 passes through the first through-hole 13 and is inserted into the locking hole 44. When repairing the electric control cabinet, after the handle 5 is switched to the second state, the operating device is switched to the anti-accidental touch mode. Under the restriction of the locking pin 6, the handle 5 cannot be switched to the first state, and the connecting shaft 3 cannot be switched to the locked state, so the closing operation cannot be performed, thereby avoiding accidents and improving the safety of maintenance.

[0047] In this embodiment, the operating device has a driving member 7, which is rotatably arranged on the handle 5 around a rotation axis 71. The extension direction of the rotation axis 71 is perpendicular to the first direction. Figure 2 、 Figure 3As shown, the driving member 7 includes a pressing portion 72 and a locking portion 73, which are disposed on opposite sides of the rotating shaft 71. Along the first direction, the pressing portion 72 is located on the side of the locking pin 6 away from the accommodating cavity 10, and the locking portion 73 is provided with a padlock hole 731. The handle 5 is provided with a receiving slot 54 for accommodating the driving member 7. When the operating handle is in the anti-accidental touch mode, the pressing portion 72 approaches the accommodating cavity 10 along the first direction, the locking portion 73 moves away from the handle 5, and the padlock hole 731 extends out of the receiving slot 54.

[0048] In this embodiment, a second inclined surface 441 is provided on the side of the locking member 4 close to the handle 5. Along the second direction, the second inclined surface 441 is located on one side of the locking hole 44. When the handle 5 is in the second state and the locking member 4 is in the first position, the second inclined surface 441 is located on the movement path of the locking pin 6 along the first direction. The second inclined surface 441 approaches the cover plate 2 along the first direction and extends obliquely toward the locking hole 44 along the second direction. Therefore, in the process of the locking pin 6 moving along the first direction into the accommodating cavity 10, the locking pin 6 can slide in cooperation with the second inclined surface 441, so that the locking member 4 is converted to the second position and the locking pin 6 is inserted into the locking hole 44, simplifying the operation. In summary, when inspecting the electric control cabinet, the handle 5 is switched to the second state to disconnect the circuit. The operator only needs to drive the pressing part 72 to move toward the mounting seat 1, and the pressing part 72 drives the locking pin 6 to move into the accommodating cavity 10. With the cooperation of the locking pin 6 and the second inclined surface 441, the locking member 4 is switched to the second position, and the locking pin 6 is inserted into the locking hole 44, and then locked at the padlock hole 731, so that the operating device is locked in the anti-accidental touch mode to prevent other people from operating it by mistake.

[0049] In this embodiment, the mounting base 1 and the cover plate 2 are connected by snapping, which makes the connection between the two easier and the disassembly operation easier. Figure 3 As shown, the mounting base 1 is fixed with a hook 14, and the cover plate 2 is provided with a slot 22, and the hook 14 is locked in the slot 22. In this embodiment, the mounting base 1 is provided with a boss 15, and the cover plate 2 is provided with a positioning slot 23, and the boss 15 is inserted into the positioning slot 23. The cooperation between the boss 15 and the positioning slot 23 facilitates the positioning of the mounting base 1 and the cover plate 2.

[0050] In this embodiment, a second sealing ring (not shown in the figure) is provided between the handle 5 and the mounting base 1 to provide sealing therebetween, thereby improving the waterproof performance.

[0051] In summary, the electric control cabinet operating device of this embodiment is provided with a limit protrusion 12 which not only limits the rotation of the handle 5, but also cooperates with the guide groove 42 to achieve accurate positioning of the locking member 4 and provide guidance for the movement of the locking member 4, thereby simplifying the structure of the operating device, improving the stability of the operating device, and improving the accuracy and stability of the movement of the locking member 4.
