[0042] Please refer to Figures 1 to 9 This utility model discloses an anti-loosening connection component 100, which is applied to a photovoltaic cleaning robot. The photovoltaic cleaning robot includes a first component and a second component. The anti-loosening connection component 100 is configured to connect the first component and the second component to improve the reliability of the first component and the second component and prevent the first component and the second component from becoming loose.
[0043] Please refer to Figures 1 to 3 This utility model also discloses a photovoltaic cleaning robot, which includes a robotic arm, a mounting base 400, a second rotary reducer 500, and a gripping mechanism 600. A swing arm 200 is rotatably mounted at the end of the robotic arm. The swing arm 200, the first rotary reducer 300, the mounting base 400, the second rotary reducer 500, and the gripping mechanism 600 are connected in pairs via anti-loosening connection components 100. This arrangement improves the reliability between each pair of the swing arm 200, the first rotary reducer 300, the mounting base 400, the second rotary reducer 500, and the gripping mechanism 600.
[0044] Please refer to Figures 1 to 8The anti-loosening connection assembly 100 includes a first fastener 1, a second fastener 2, and an anti-deviation component 3. The first fastener 1 includes a first head 11 and a first threaded portion 12 disposed on one side of the first head 11. A first threaded hole 13 is provided on the other side of the first head 11. The wall of the first threaded hole 13 has a first threaded portion 131. A second threaded portion 121 is provided on the outer periphery of the first threaded portion 12.

The first threaded portion 12 passes through the first component and connects to the second component. The second fastener 2 includes a second head 21 and a second threaded portion 22 disposed on one side of the second head 21. The second threaded portion 22 is threadedly engaged with the first threaded portion 131. The anti-deviation component 3 is disposed between the first head 11 and the second head 21. The first threaded portion 12 passes through the anti-deviation component 3, and the opposite sides of the anti-deviation component 3 are respectively connected to the first component. This improves the reliability between the first and second components and prevents the connection from loosening due to vibration.
[0045] Please refer to Figures 6 to 8 The first threaded hole 13 is provided along the extension direction of the central axis of the first head 11. Preferably, the central axis XX of the first head 11 is collinear with the axis of the first screw portion 12. The first head 11 includes a first top surface 111 and a first bottom surface 112 disposed opposite each other. The first screw portion 12 is disposed on the first bottom surface 112 of the first head 11 along the extension direction of the central axis XX. The first threaded hole 13 extends from the first top surface 111 of the first head 11 into a portion of the first screw portion 12 along the extension direction of the central axis XX. In other embodiments, the first threaded hole 13 extends from the first top surface 111 to the first bottom surface 112 along the extension direction of the central axis XX of the first head 11, which is not limited here.
[0046] Please refer to Figures 6 to 8 The second screw portion 22 has a third threaded portion 221 on its exterior, which is threadedly engaged with the first threaded portion 131. Preferably, the third threaded portion 221 and the first threaded portion 131 have the same thread direction, while the second threaded portion 121 has the opposite thread direction. That is, the third threaded portion 221 and the first threaded portion 131 are reverse threads, and the second threaded portion 121 is a straight thread. In other embodiments, the third threaded portion 221 and the first threaded portion 131 are straight threads, and the second threaded portion 121 is a reverse thread. All of the above embodiments ensure that the first fastener 1 and the second fastener 2, after being assembled into the first component, are tightly screwed together and are not prone to loosening. When the second screw portion 22 is threadedly connected to the first threaded portion 131 of the first head 11, and the first screw portion 12 is threadedly connected to the first component, the first fastener 1 and the second fastener 2 are screwed in opposite directions to achieve an anti-loosening effect, thereby improving reliability.
[0047] Please refer to Figures 7 to 9 The anti-deviation component 3 includes a main body 31 and two fixing parts 32 disposed on both sides of the main body 31 along its length. The main body 31 has a first fixing hole 301 at its center. A second screw part 22 passes through the first fixing hole 301 and is threadedly connected to a first threaded part 131. The fixing parts 32 have second fixing holes 302. The anti-loosening connection assembly 100 also includes a third fastener 4, which passes through the second fixing hole 302 and is connected to the second component. The anti-deviation component 3 also includes connecting parts 34, which are vertically disposed at both ends of the main body 31 along its length. The fixing parts 32 are vertically disposed at the connecting parts 34, and both fixing parts 32 extend outward from the connecting parts 34. Preferably, the height of the connecting parts 34 matches the thickness of the first head 11. When the anti-deviation component 3 is fixedly connected to the second component, the two connecting parts 34, the main body 31, and the second component form a receiving space to receive the first head 11. The second screw portion 22 of the second fastener 2 passes through the first fixing hole 301 and is threadedly connected to the first threaded hole 13. At this time, the first fastener 1, the second fastener 2 and the anti-deviation component 3 are more stable, so as to ensure that the connection between the first component and the second component is more stable.
[0048] Please refer to Figures 7 to 9 The anti-deviation component 3 also includes two abutment portions 33, which are respectively disposed on both sides of the main body portion 31 in the width direction. The second head 21 is disposed between the two abutment portions 33 and abuts against the two abutment portions 33. The two abutment portions 33 are respectively vertically disposed on both sides of the main body portion 31 in the width direction and are symmetrically disposed with respect to the first fixing hole 301 of the main body portion 31. Preferably, the abutment portions 33 extend vertically upward from the main body portion 31 so that a mounting groove is formed between the two abutment portions 33 and the main body portion 31. After the second fastener 2 passes through the first fixing hole 301 of the main body portion 31, the second head 21 abuts against the main body portion 31. The second head 21 is located in the mounting groove. At this time, the two abutment portions 33 abut against the second head 21 respectively to restrict the rotation of the second fastener 2, further improving the reliability of the anti-loosening connection assembly 100.
[0049] Preferably, the two abutment portions 33 are respectively disposed on opposite sides of the first fixing hole 301. The two abutment portions 33 are arranged parallel to each other. Preferably, the second head 21 of the second fastener 2 is hexagonal. The vertical distance between the two abutment portions 33 matches the distance between the two opposite edges of the second head 21, thus enabling the second head 21 to be fitted between the two abutment portions 33 and restricting the rotation of the second head 21. In the embodiment of this application, the abutment portion 33 forms an angle with the long side of the main body portion 31. Preferably, the angle ranges from 0 to 90°. This arrangement improves the reliability of the assembly of the second fastener 2 and the anti-deviation component 3.
[0050] The anti-deviation component 3 is formed by integral bending. The integral bending process improves the overall structural strength of the anti-deviation component 3 and reduces the occurrence of breakage.
