[0032] Please refer to Figures 1 to 9 As shown, this utility model discloses a clamp for fixing a control box to the main shaft of a photovoltaic bracket. The clamp includes a first clamp 1, a second clamp 2, and a fastening assembly 3. One end of the first clamp 1 is connected to one end of the second clamp 2 via a plug-in structure, and the other end of the first clamp 1 is connected to the other end of the second clamp 2 via the fastening assembly 3. The first clamp 1 and the second clamp 2 together form a ring around the main shaft. The end of the first clamp 1 or the second clamp 2 furthest from the main shaft is used to install the control box. The plug-in structure replaces the bolt connection, facilitating the connection between the first clamp 1 and the second clamp 2.

[0033] In this embodiment, the first clamp 1 is the upper clamp, and the second clamp 2 is the lower clamp. The first clamp 1 and the second clamp 2 are arranged vertically, and the control box 100 is connected to the lower clamp. Of course, in other possible embodiments, the first clamp 1 is the lower clamp, the second clamp 2 is the upper clamp, and the control box 100 is connected to the upper clamp.

[0034] See Figure 2 The first clamp 1 includes a first clamp body 11, a first ear 12 connected to one end of the first clamp body 11, and a second ear 13 connected to the other end of the first clamp body 11. The second clamp 2 has a slot 230 at one end for the first ear 12 to be inserted into, and a third ear 22 at the other end. The second ear 13 and the third ear 22 are connected by a fastening assembly 3. The insertion structure includes the first ear 12 and the slot 230. By inserting the first ear 12 into the slot 230, one end of the first clamp 1 and one end of the second clamp 2 are connected, facilitating rapid clamp installation. Using an insertion method instead of bolt fixing improves installation efficiency and reduces the amount of bolts used, thus lowering costs.

[0035] When the first clamp 1 and the second clamp 2 are fitted together on the main shaft, the inner wall of the clamp matches the outer contour of the main shaft. This application is applicable to main shafts of various shapes, such as square tubes, round tubes, pentagonal tubes, and R-angle square tubes.

[0036] In this embodiment, the clamp is suitable for R-angle square tubes. For details, see [link to details]. Figure 6 The first clamp body 11 includes a first wall portion 111, a first side portion 112 connected to the first ear portion 12, a first connecting portion 113 connecting the first side portion 112 and the first wall portion 111, a second side portion 114 connected to the second ear portion 13, and a second connecting portion 115 connecting the second side portion 114 and the first wall portion 111. The first connecting portion 113 and the second connecting portion 115 are both arc-shaped structures, which can better adapt to the shape of the main shaft and improve the connection stability between the clamp and the main shaft.

[0037] In this embodiment, the first clamp 1 is manufactured using a bending process, which makes it easy to produce.

[0038] See Figure 2 The second clamp 2 includes a second clamp body 21 and a fourth ear 23 connected to one end of the second clamp body 21, and a third ear 22 connected to the other end of the second clamp body 21. The slot 230 includes the space between the fourth ear 23 and the second clamp body 21, and the insertion interface 2301 of the slot 230 is located at the connection between the second clamp body 21 and the fourth ear 23. During assembly, the first ear 12 passes through the insertion interface 2301, extends into the slot 230, and abuts against the bottom surface of the fourth ear 23. The first ear 12 and the fourth ear 23 are installed alternately, mutually constraining each other, making assembly convenient.

[0039] See Figure 8 The second clamp body 21 includes a base 211 and side portions 212 connected to both sides of the base 211. A third ear portion 22 and a fourth ear portion 23 are connected to both ends of the base 211. A mounting cavity 210 is formed between the base 211 and the two side portions 212. The two side portions 212 cooperate with the first clamp 1 to surround the outer periphery of the spindle. The base 211 is provided with a mounting hole 2110, which is configured to mount the control box 100. See also... Figure 9 In this embodiment, the control box 100 is connected to the second clamp 2 via the connector 200, and the mounting cavity 210 is used to house the connector 200 to avoid the connector 200 interfering with the spindle.

[0040] See Figure 8 The base 211 includes a second wall portion 2111, a third side portion 2112 connecting the second wall portion 2111 and the third ear portion 22, and a fourth side portion 2113 connecting the second wall portion 2111 and the fourth ear portion 23. The mounting hole 2110 passes through the second wall portion 2111.

[0041] See also Figure 8 Each edge 212 is provided with a weight reduction hole 2120, which is a bent elongated hole used to reduce the weight of the hoop.

[0042] See Figure 5 An assembly gap 10 is formed between the second ear 13 and the third ear 22. After the fastening assembly 3 is tightened, the first clamp 1 and the second clamp 2 can be locked to the main shaft. By setting the assembly gap 10, it is convenient for the fastening assembly 3 to lock the first clamp 1 and the second clamp 2.

[0043] In this embodiment, see Figure 6 and Figure 7 Along the arrangement direction HH of the first clamp 1 and the second clamp 2, the distance between the first ear 12 and the first wall 111 is greater than the distance between the second ear 13 and the first wall 111, and the distance between the third ear 22 and the second wall 2111 is less than the distance between the fourth ear 23 and the second wall 2111. That is, there is a height difference between the first ear 12 and the second ear 13, and there is a height difference between the third ear 22 and the fourth ear 23. The second ear 13 is raised relative to the first ear 12, and the third ear 22 is lowered relative to the fourth ear 23, thereby forming an assembly gap 10 between the second ear 13 and the third ear 22.

[0044] In another embodiment, along the arrangement direction HH of the first clamp 1 and the second clamp 2, the distance between the first ear 12 and the first wall 111 is greater than the distance between the second ear 13 and the first wall 111. The third ear 22 and the fourth ear 23 are at the same height. The second ear 13 is raised a greater distance relative to the first ear 12, so that an assembly gap 10 is formed between the second ear 13 and the third ear 22.

[0045] In another embodiment, along the arrangement direction HH of the first clamp 1 and the second clamp 2, the distance between the third ear 22 and the second wall portion 2111 is less than the distance between the fourth ear 23 and the second wall portion 2111. The first ear 12 and the second ear 13 are at the same height, and the third ear 22 is lowered by a larger distance relative to the fourth ear 23, so that an assembly gap 10 is formed between the second ear 13 and the third ear 22.

[0046] See Figure 2 The third ear portion 22 has a first reinforcing portion 24 connected to both sides, and the first reinforcing portion 24 is also connected to the base portion 211. See also Figure 4 The fourth ear 23 is connected to the second reinforcing part 26 on both sides. The second reinforcing part 26 is also connected to the base 211. The fourth ear 23, the base 211 and the second reinforcing part 26 together form the slot 230.

[0047] In this embodiment, the second clamp 2 is made by casting, forming a single piece with an aesthetically pleasing design.

[0048] See Figure 2 The fastening assembly 3 includes a bolt 31 and a nut 32. The second ear 13 is provided with a first through hole 130, and the third ear 22 is provided with a second through hole 220. The bolt 31 passes through the first through hole 130 and the second through hole 220 and is fixed with the nut 32.

[0049] See Figure 2 The third ear 22 has a limiting part 25 on the side facing away from the second ear 13. The limiting part 25 has a limiting groove 250, and the nut 32 is disposed in the limiting groove 250. By setting the limiting part 25, the nut 32 is prevented from loosening later. During assembly, the nut 32 is installed in the limiting groove 250 and the bolt 31 is rotated to tighten it.

[0050] In this embodiment, see Figure 2 The limiting part 25 includes a first limiting part 251 and a second limiting part 252. The first limiting part 251 and the second limiting part 252 are also connected to two first reinforcing parts 24 respectively. The limiting groove 250 includes the space between the first limiting part 251 and the second limiting part 252.
