[0042] like Figure 1 to Figure 8 As shown, this embodiment proposes a power regulator with a quick-release function, including a chassis 1 with a first inner cavity 101, an electrical component 2 arranged in the first inner cavity 101, and a cover plate 3 for snap-fitting with the chassis 1, the chassis 1 also has a second inner cavity 102 and a through hole 103, the second inner cavity 102 is located at the lower end of the through hole 103, and is connected to the through hole 103; the positioning platform 4 is slidably arranged on the cover plate 3, and the positioning platform 4 is aligned with the through hole 103 after sliding, and the positioning platform 4 has a positioning groove 5, and the positioning groove 5 is located on the outer wall of the positioning platform 4; the positioning block 6 is swingably arranged in the second inner cavity 102, and the positioning block 6 drives the positioning block 6 to swing after passing through the through hole 103, and the positioning block 6 is used to snap-fit ​​with the positioning groove 5.

[0043] In this embodiment, the chassis 1 is designed with a first inner cavity 101, with built-in electrical components 2, which are responsible for function execution and power adjustment, such as power adjustment. The cover plate 3 and the chassis 1 are snap-fitted, which is convenient for quick disassembly and assembly, and at the same time protects the electrical components 2 in the first inner cavity 101. The second inner cavity 102 and the through hole 103 are arranged on the chassis 1, and the cover plate 3 is slidably mounted with a positioning platform 4. When the operator needs to snap-fit ​​the cover plate 3 and the chassis 1, the positioning platform 4 and the through hole 103 on the chassis 1 can be aligned, and then the cover plate 3 is pressed down, so that the positioning platform 4 passes through the through hole 103 and enters the second inner cavity 102. At this time, the operator needs to continue to press the cover plate 3, so that the positioning platform 4 drives the positioning block 6 in the second inner cavity 102, so that the positioning block 6 swings, so that the positioning block 6 is snap-fitted with the positioning slot 5 on the positioning platform 4, and at this time, the bottom of the cover plate 3 contacts the upper part of the chassis 1, and the cover plate 3 and the chassis 1 are snap-fitted. When it is necessary to remove the cover plate 3 from the chassis 1, the operator can pull up the cover plate 3 to swing the positioning block 6, so that the positioning block 6 and the positioning groove 5 on the positioning platform 4 cancel the clamping fit, so that the cover plate 3 and the chassis 1 cancel the clamping fit, and the chassis 1 and the cover plate 3 are quickly disassembled. Through the swinging fit of the positioning platform 4 and the positioning block 6, the operator can quickly disassemble the chassis 1 and the cover plate 3, which is convenient for maintenance and repair without tools.

[0045] like Figure 3 In the embodiment shown, when the positioning platform 4 passes through the through hole 103 and enters the second inner cavity 102 on the chassis 1, the positioning platform 4 contacts the top of the moving rod 701. When the operator presses down the cover plate 3, the moving rod 701 moves downward along the height direction of the chassis 1, so that the swing arm 702 on the left side of the moving rod 701 swings clockwise, so that the positioning block 6 on the left swing arm 702 of the moving rod 701 is close to the positioning groove 5 on the positioning platform 4, so that the positioning block 6 on the left swing arm 702 of the moving rod 701 is engaged, so that the cover plate 3 and the chassis 1 are engaged. It should be noted that a spring is provided in the second inner cavity 102, and the two ends of the spring act on the bottom of the moving rod 701 and the inner wall of the second inner cavity 102 respectively, and the spring is used to provide a force for the moving rod 701 to move away from the bottom of the second inner cavity 102. When the cover 3 and the chassis 1 need to be disassembled, the operator can move the movable rod 701 upward and rotate the swing arm 702 on the left side of the movable rod 701 counterclockwise to disengage the locking block 6 and the locking slot 5. Then the operator can remove the cover 3 from the chassis 1, thereby realizing quick disassembly and assembly of the chassis 1 and the cover 3.

[0046] Optionally, the chassis 1 also has a positioning groove 104, which is connected to the second inner cavity 102 and is located below the through hole 103, and the axis of the positioning groove 104 is perpendicular to the axis of the through hole 103; it also includes: one end of the first elastic member 8 is arranged on the outer wall of the moving rod 701; the positioning slide bar 9 is arranged on the other end of the first elastic member 8, and the first elastic member 8 is used to provide a force for the positioning slide bar 9 to move away from the moving rod 701 in the radial direction of the moving rod 701.

In a normal state, the first elastic member 8 is in a compressed state, and the left side of the positioning slide bar 9 abuts against the left side wall of the second inner cavity 102. When the moving rod 701 moves downward along the height direction of the chassis 1, the positioning slide bar 9 follows the movement. When the moving rod 701 drops to a certain height, the positioning block 6 and the positioning groove 5 are engaged, and the positioning slide bar 9 enters the positioning groove 104, and the cover plate 3 and the chassis 1 are engaged. When the cover plate 3 and the chassis 1 need to be disassembled, the operator can press the positioning slide bar 9 back into the second inner cavity 102, and then pull the cover plate 3 upward to slide the moving rod 701 upward, so that the positioning block 6 and the positioning groove 5 cancel the engagement, and the cover plate 3 and the chassis 1 cancel the engagement.

[0048] Optionally, it also includes: a moving block 10 is slidably set at the lower end of the cover plate 3, and the positioning platform 4 is slidably connected to the cover plate 3 through the moving block 10; two ends of the second elastic member 11 act on the moving block 10 and the cover plate 3 respectively, and the second elastic member 11 is used to provide a force for the moving block 10 to move away from the cover plate 3.

[0049] In this embodiment, when the operator aligns the positioning platform and the through hole 103 , the operator can move the moving block 10 to the left to compress the second elastic member 11 so as to align the positioning platform 4 and the through hole 103 .

[0051] like Figure 3In the embodiment shown, when the moving rod 701 moves downward, the swing arm 702 located on the left side of the moving rod 701 rotates clockwise, and the swing arm 702 located on the right side of the moving rod 701 rotates counterclockwise, so that the two locking blocks 6 on the two swing arms 702 on the left side and the right side of the moving rod 701 respectively abut against the two locking grooves 5 on the locking platform 4, so that the cover plate 3 and the chassis 1 are locked together, which can make the locking fit between the cover plate 3 and the chassis 1 more stable and firm.

[0052] Optionally, there are multiple movable blocks 10 , multiple second elastic members 11 , multiple positioning platforms 4 , multiple second inner cavities 102 , multiple swing drive devices 7 , and multiple positioning blocks 6 .

[0053] Optionally, there are multiple positioning grooves 104, multiple positioning slide bars 9, and multiple first elastic members 8.

At the same time, a positioning groove 104 connected to the second inner cavity 102 is provided on the side of each second inner cavity 102, and a positioning slide bar 9 and a first elastic member 8 are provided on each movable rod 701. When the cover 3 needs to be removed from the chassis 1, the four positioning slide bars 9 need to be pressed from the positioning groove 104 into the second inner cavity 102, and then the cover 3 is pulled up to move the movable rod 701 upward, so that each set of swing drive devices 7 and the locking groove 5 are cancelled, and then the cover 3 and the chassis 1 are disassembled, thereby reducing the possibility of the cover 3 and the chassis 1 being separated due to accidental touch by the operator.

[0055] Optionally, it also includes: a tray 12 is arranged in the chassis 1 and located above the electrical component 2, and the tray 12 is used to install the control board.
