[0046] like Figures 1 to 7 As shown, this embodiment provides a control box locking device, which includes a control box 11, a main box body 12 and a locking structure. The control box 11 is clamped to the main box body 12 through the locking structure. The locking structure includes a drive component 20 and a clamping member 30. The drive component 20 is rotatably connected to the control box 11. The drive component 20 has a locked state in which it is clamped to the control box 11 and an unlocked state in which it rotates relative to the control box 11; the clamping member 30 is connected to the drive component 20 and is at least partially slidably arranged in the control box 11. The rotation of the drive component 20 can drive the clamping member 30 to slide in the control box 11, so that the clamping member 30 is clamped to the main box body 12.

[0047] By setting the driving component 20 and the clamping member 30, when the driving component 20 is in the unlocked state, the driving component 20 is rotated to drive the clamping member 30 to slide in the control box 11, thereby pushing the clamping member 30 to the corresponding position of the main box body 12 and clamping it with the main box body 12, and then the driving component 20 is clamped with the control box 11 to keep the driving component 20 in the locked state, thereby installing the control box 11 on the main box body 12; when the control box 11 needs to be removed, it is only necessary to operate the driving component 20 with one hand to make the driving component 20 reach the unlocked state, and rotate the driving component 20 to drive the clamping member 30 out of the clamping position with the main box body 12. The structure is simple and easy to operate, and can be quickly disassembled and assembled with one hand for easy maintenance.

[0048] Specifically, two clamping members 30 are provided, one clamping member 30 connected to each side of the drive assembly 20, thereby driving the two clamping members 30 to move synchronously. By providing two clamping members 30, the two clamping members 30 engage with the main case 12 at different positions on both sides, thereby ensuring the stability of the connection between the control box 11 and the main case 12 and preventing a gap between the control box 11 and the main case 12 due to loosening of the clamping joint.

[0049] See also Figure 6 In this embodiment, the first direction is the length direction of the control box 11, and the second direction is the thickness direction of the control box 11; the two clamping members 30 both extend along the first direction, and the two clamping members 30 are arranged opposite to each other; the clamping members 30 are sheet-shaped; this embodiment describes one of the clamping members 30 as an example, and the structures and settings of the two clamping members 30 are the same.

[0050] See also Figures 1 to 4 The clamping member 30 is provided with a clamping end 32, and the main housing 12 is provided with a clamping portion 121. The clamping end 32 is engaged with the clamping portion 121. The clamping end 32 moves with the clamping member 30. When the clamping end 32 moves to the position of the clamping portion 121, the clamping end 32 is engaged with the clamping portion 121, thereby fixing the control box 11 to the main housing 12. In this embodiment, each of the two clamping members 30 is provided with two clamping ends 32, and the main housing 12 is provided with four clamping portions 121. Optionally, both the clamping end 32 and the clamping portion 121 are provided with guiding inclined surfaces to ensure smooth engagement between the clamping end 32 and the clamping portion 121.

[0051] See also Figure 8 and Figure 9 Furthermore, the drive assembly 20 includes a main body 21 and a locking member 22. The main body 21 is rotatably connected to the control box 11 and connected to the clamping member 30. The locking member 22 is rotatably disposed within the main body 21. A first end of the locking member 22 is connected to the main body 21 via an elastic member 24, and a second end of the locking member 22 is engaged with the control box 11. The elastic member 24 may be a spring. By providing the main body 21 and arranging the locking member 22 within the main body 21, the locking member 22 is rotatably connected to the main body 21. When the locking member 22 is controlled to rotate, the first end of the locking member 22 presses against the elastic member 24, and the second end tilts up, thereby disengaging from the control box 11, thereby unlocking the drive assembly 20. When the external force is removed, the locking member 22 can be reset under the action of the elastic member 24. In this embodiment, the main body 21 is a handle, and a clamping member 30 is connected to each end of the handle; the locking member 22 is sheet-shaped; and the elastic member 24 is a spring (the specifications of the spring can be: wire diameter 0.8mm, outer diameter 6mm, length 12mm).

[0052] In this embodiment, a hook 111 is provided on the control box 11. When the second end of the locking member 22 is engaged with the hook 111, the drive assembly 20 is in a locked state; the control box locking device also includes a third connecting member 60, and the main body 21 is rotatably set on the control box 11 through the third connecting member 60; the third connecting member 60 can be an M5×25 flat head cross screw; the control box locking device also includes a rotating connecting member 26, and the locking member 22 is rotatably set on the control box 11 through the rotating connecting member 26; the rotating connecting member 26 can be an M4×12 cross screw.

[0053] In order to enable the clamping member 30 to slide within the control box 11 when the main body 21 rotates, the control box locking device further includes a first connecting member 40. The clamping member 30 is provided with a guide hole 311. One end of the first connecting member 40 is rotatably connected to the main body 21, and the other end of the first connecting member 40 is slidably disposed within the guide hole 311. Rotation of the main body 21 can drive the first connecting member 40 to slide within the guide hole 311. By providing the guide hole 311 and the first connecting member 40, the first connecting member 40 slides within the guide hole 311 when the main body 21 rotates.

[0054] In this embodiment, the second direction is the length direction of the guide hole 311 , and the first connecting member 40 is slidably inserted into the guide hole 311 ; the first connecting member 40 is an M4×10 threaded screw.

[0055] Optionally, the control box locking device also includes a bead screw 70, which is inserted through the main body 21. Rotation of the main body 21 drives the end of the bead screw 70 against the control box 11. By providing the bead screw 70, when the main body 21 rotates to a certain extent, the bead screw 70 restricts the rotation of the main body 21. In this embodiment, the bead screw 70 has a nominal diameter of 4 mm and a length of 10 mm. The structure, configuration, and principle of the bead screw 70 can be referred to in the prior art and will not be further described here.

[0056] To limit the sliding direction of the clamping member 30 within the control box 11, the control box locking device further includes a second connecting member 50. The second connecting member 50 is connected to the control box 11. The clamping member 30 is provided with a waist-shaped hole 312, and the second connecting member 50 is slidably disposed within the waist-shaped hole 312. By arranging the second connecting member 50 and the waist-shaped hole 312 to cooperate, when the clamping member 30 slides, the second connecting member 50 slides along the inner wall of the waist-shaped hole 312, thereby limiting the sliding direction of the clamping member 30.

[0057] Optionally, at least two waist-shaped holes 312 are provided at intervals, and the second connecting members 50 are provided in a one-to-one correspondence with the waist-shaped holes 312. In this embodiment, the first direction is the length direction of the waist-shaped holes 312, and the second connecting members 50 are provided in the waist-shaped holes 312; three second connecting members 50 are provided side by side at intervals along the first direction; and the second connecting members 50 are M4×14 flat head Phillips screws.

[0058] To restrict the relative position of the control box 11 and the main housing 12, the control box locking device also includes a positioning member 112. The two ends of the positioning member 112 are inserted into the control box 11 and the main housing 12, respectively. The positioning member 112 can restrict the relative position of the control box 11 and the main housing 12, ensuring the accurate installation position of the control box 11. In this embodiment, the positioning member 112 is a positioning pin; at least two positioning members 112 are provided at intervals.

[0059] Optionally, the drive assembly 20 further includes a button 23 disposed on the exterior of the main body 21. The button 23 is connected to the locking member 22 and is configured to press the locking member 22 to cause the locking member 22 to press against the elastic member 24. By providing the button 23, when the handle is held with one hand, the finger pressing the button 23 can control the rotation of the locking member 22 to unlock the drive assembly 20. When the finger releases the button 23, the locking member 22 automatically resets.

[0060] In this embodiment, two locking members 22 are provided, and two buttons 23 are also provided. Each button 23 corresponds to a locking member 22, thereby driving a clamping member 30; the control box locking device also includes a fastener 25, and the button 23 is fixed to the locking member 22 through the fastener 25; there are two fasteners 25; the fastener 25 can be a PM2.5 round head screw.

[0061] Optionally, a cylindrical protrusion 221 is provided at the first end of the locking member 22, and the elastic member 24 is at least partially mounted on the cylindrical protrusion 221. The provision of the cylindrical protrusion 221 facilitates the installation of the elastic member 24 and the locking member 22, and allows the end of the elastic member 24 to abut against the locking member 22. In this embodiment, the elastic member 24 is partially mounted on the cylindrical protrusion 221, and the ends of the elastic member 24 abut against the main body 21 and the locking member 22, respectively.

[0062] If Figure 8 and Figure 9 As the initial state of the control box locking device, the locking member 22 is engaged with the hook 111 (the drive assembly 20 is in the locked state), and the engaging end 32 of the clamping member 30 is engaged with the engaging portion 121 of the main box body 12; when the button 23 is pressed, Figure 10 and Figure 11The locking member 22 rotates a certain angle along the X1 direction with the rotating connecting member 26 as the center. The first end of the locking member 22 presses the elastic member 24 against the main body 21. The elastic member 24 is compressed, and the second end of the locking member 22 is disengaged from the hook 111 (the driving assembly 20 reaches the unlocked state). At this time, the first connecting member 40 is located at the top of the guide hole 311. Then, the main body 21 is rotated along the Y1 direction. Figures 12 to 14 As the main body 21 rotates along the Y1 direction, the first connecting member 40 slides to the bottom end of the guide hole 311. At the same time, the clamping member 30 slides in the control box 11, and the clamping member 30 moves along the first direction toward the direction close to the hook 111, so that the clamping end 32 of the clamping member 30 is disengaged from the clamping portion 121 of the main box body 12.

[0063] The following is the specific installation and use process of the control box locking device:

[0064] First, pass the tail end of the main body 21 through the control box 11, use the first connecting member 40 to fix the main body 21 and the clamping member 30, then rotatably fix the main body 21 to the control box 11 through the third connecting member 60, and use the second connecting member 50 to fix the clamping member 30 to the control box 11, so that when the main body 21 rotates, the clamping member 30 can be driven to slide along the first direction in the control box 11.

[0065] Subsequently, the locking member 22 and the elastic member 24 are installed in the main body 21 using the rotating connecting member 26, and the button 23 is fixed to the locking member 22 using the fastener 25, so that the button 23 can be pressed to drive the locking member 22 to rotate and realize rotational locking; and then the bead screw 70 is fixed to the main body 21 to realize rotational limiting.

[0066] See also Figure 14 When in use, make sure that the locking piece 22 is disengaged from the hook 111 to ensure that the drive assembly 20 can rotate relative to the control box 11 (that is, the drive assembly 20 is in the unlocked state). Hold the main body 21 with one hand and place the entire control box 11 with the locking structure on the main box 12, so that the two ends of the positioning piece 112 are respectively inserted into the control box 11 and the main box 12, and then determine the relative position of the control box 11 and the main box 12 to ensure installation accuracy.

[0067] After the control box 11 is placed in place, the hand-held body 21 rotates along the Y2 direction. During the rotation, the clamping member 30 is driven to slide in the control box 11. The clamping member 30 moves along the first direction toward the direction away from the hook 111. The clamping end 32 of the clamping member 30 is engaged with the clamping portion 121 of the main box body 12, thereby installing the control box 11 on the main box body 12.

[0068] See also Figure 11The main body 21 is rotated in the Y2 direction so that the second end of the locking member 22 approaches the hook 111. The hook 111 acts as a push on the locking member 22, causing the locking member 22 to rotate a certain angle in the X1 direction around the rotating connecting member 26. The first end of the locking member 22 presses the elastic member 24 against the main body 21, compressing the elastic member 24 and causing the second end of the locking member 22 to tilt up. Figure 9 Under the action of the elastic member 24, the second end of the locking member 22 is lifted and then engages with the hook 111 and automatically resets. At this time, the main body 21 cannot continue to rotate (the drive assembly 20 reaches the locked state). It is understood that during installation, the locking member 22 can be lifted by the hook 111, so there is no need to press the button 23. When removing the control box 11, pressing the button 23 can control the rotation of the locking member 22, thereby disengaging the locking member 22 from the hook 111.

[0069] The locking member 22 is used to lock the main body 21 as a safety device to prevent accidental unlocking. The entire operation process is concentrated on the drive component 20 and is suitable for holding the main body 21 with one hand and operating the button 23, realizing quick operation by one person with one hand.
