[0088] The thickness of the outward turning edge 250 can be greater than the thickness of the boss 240, or the thickness of the outward turning edge 250 can be less than or equal to the thickness of the boss 240.

[0089] The inner side wall of the outward turning edge 250 forms the first matching part 210.

[0090] The wall surface of the main shaft 100 is clamped between the outward turning edge 250 and the boss 240.

[0094] In the embodiment, the first cooperation part 210 of the outer flange 250 and the second cooperation part 220 of the convex boss 240 can be in interference fit with the main shaft 100 at the same time.

[0095] The interference fit of the first cooperation part 210 and the second cooperation part 220 with the main shaft 100 can adopt various structures, such as increasing a sealing structure on the first cooperation part 210 and the second cooperation part 220 or increasing the cross-sectional width of the first cooperation part 210 and the second cooperation part 220, and the embodiment is not limited specifically.

[0100] In the embodiment, the first tooth 211 and the second tooth 221 are both multiple, have a larger contact area, and have a good sealing effect.

[0101] It should be noted that the tooth angle of the first tooth 211 and the second tooth 221 can be designed as an acute angle, a right angle or an obtuse angle, or the above chamfering is further matched with chamfering, and the embodiment is not limited specifically.

[0102] As shown in Figure 5 、 Figure 9 andFigure 14 As shown, the first tooth 211 is in interference fit with the outer peripheral wall of the main shaft 100, and the second tooth 221 is in interference fit with the inner peripheral wall of the main shaft 100.

[0103] The first tooth 211 can include a first guide surface 2111.

[0104] The first guide surface 2111 is located on a side of the first tooth 211 away from the cover body 230.

[0105] The first guide surface 2111 is inclined in a direction close to the cover body 230 along a direction away from the outer side surface of the outer flange 250.

[0106] In the embodiment, the first tooth 211 is located in the first fitting portion 210, the tooth tip of the first tooth 211 is directed towards the boss 240, the first guide surface 2111 is located on a side of the first tooth 211 away from the cover body 230, and the first guide surface 2111 is inclined in a direction close to the cover body 230 along a direction close to the tooth tip. As a result, the first tooth 211 is easier to be fitted into the main shaft 100, and the sealing fit effect is better, and the first tooth 211 is less likely to be detached from the main shaft 100.

[0107] The second tooth 221 can include a second guide surface 2211.

[0108] The second guide surface 2211 is located on a side of the second tooth 221 away from the cover body 230.

[0109] The second guide surface 2211 is inclined in a direction close to the cover body 230 along a direction close to the outer flange 250.

[0110] In the embodiment, the second tooth 221 is located in the second fitting portion 220, the tooth tip of the second tooth 221 is directed towards the outer flange 250, the second guide surface 2211 is located on a side of the second tooth 221 away from the cover body 230, and the second guide surface 2211 is inclined in a direction close to the cover body 230 along a direction close to the tooth tip. As a result, the second tooth 221 is easier to be fitted into the main shaft 100, and the sealing fit effect is better, and the second tooth 221 is less likely to be detached from the main shaft 100.

[0111] According to the photovoltaic support 10 provided in the embodiments, the first guide surface 2111 of the first tooth 211 is inclined in a direction close to the cover body 230 along a direction away from the outer side surface of the outer flange 250, and the second guide surface 2211 of the second tooth 221 is inclined in a direction close to the cover body 230 along a direction close to the outer flange 250. As a result, the first tooth 211 and the second tooth 221 are easier to be fitted into the main shaft 100, and the sealing fit effect is better, and the main shaft 100 is less likely to be detached.

[0112] In some embodiments, as Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 13 and Figure 14As shown, there may be a plurality of first teeth 211 and a plurality of second teeth 221 .

[0113] The first teeth 211 and the second teeth 221 may have at least one of the following structural forms:

[0114] First, as Figure 5 、 Figure 9 and Figure 14 As shown, part of the first teeth 211 and the second matching portion 220 are staggered, and part of the second teeth 221 and the first matching portion 210 are staggered.

[0115] In this embodiment, part of the first teeth 211 corresponds to part of the second teeth 221 , and part of the first teeth 211 is staggered with part of the second teeth 221 , thereby increasing the contact area with the main shaft 100 and achieving a better sealing effect.

[0119] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting a plurality of first teeth 211 and second teeth 221, and staggering some or all of the first teeth 211 and the second matching parts 220, and staggering some or all of the second teeth 221 and the first matching parts 210, the contact area with the main shaft 100 is increased, and the sealing effect is better.

[0120] In some embodiments, as Figure 5 、 Figure 9 and Figure 14 As shown, the first mating portion 210 may form a first groove 260 .

[0121] The first groove 260 is located between the first matching portion 210 and the cover body 230 .

[0122] It should be noted that the provision of the first groove 260 between the first mating part 210 and the cover body 230 can avoid stress concentration at the edge, which may lead to structural damage or failure. It can also absorb the deformation caused by thermal expansion and contraction and extrusion of the cover body 230 and the first mating part 210, thereby improving the overall strength of the main shaft cover 200 structure, and can reduce processing difficulty and reduce processing costs.

[0123] The second tooth 221 can be partially arranged opposite to the first slot 260, or the second tooth 221 can be completely arranged opposite to the first slot 260.

[0124] In the embodiment, as shown in Figure 5 , Figure 9 and Figure 14 , the second tooth 221 can be partially arranged opposite to the first slot 260, which ensures the stability of the clamping of the second tooth 221 to the main shaft 100 and increases the contact area of the first tooth 211 and the second tooth 221 to the main shaft 100, and the sealing effect is better.

[0125] The turned-up edge 250 protrudes in a direction away from the cover body 230 relative to the boss 240.

[0126] In the embodiment, the width of the turned-up edge 250 is greater than the width of the boss 240, and the clamping effect on the main shaft 100 is better.

[0127] The first tooth 211 can be partially arranged on the part of the turned-up edge 250 protruding relative to the boss 240, or the first tooth 211 can be completely arranged on the part of the turned-up edge 250 protruding relative to the boss 240.

[0128] The first tooth 211 and the second tooth 221 can be made of anti-aging plastic material, so as to avoid aging of the material of the main shaft cover 200 due to long-term wind and sun, and loosening.

[0129] It should be noted that in the embodiment, the main shaft cover 200 needs to work in the working condition of sun and rain, and the main shaft cover 200 can be completely made of anti-aging plastic material, which includes polyethylene, polypropylene, polyurethane, and polycarbonate, etc. In the embodiment, no specific limitation is made, and the main shaft cover 200 made of anti-aging plastic material can avoid aging of the material due to long-term wind and sun, and loosening.

[0130] In assembly, the first tooth 211 of the main shaft cover 200 first contacts the main shaft 100, and the second tooth 221 contacts the main shaft 100 later in the process of the main shaft cover 200 contacting the main shaft 100. Since the main shaft cover 200 is made of anti-aging plastic material, the first tooth 211 and the second tooth 221 are deformed when contacting the main shaft 100, achieving the purpose of double-layer fastening and sealing, and the sealing effect is better.

[0131] In the embodiment, the first tooth 211 can be partially arranged on the part of the turned-up edge 250 protruding relative to the boss 240, and the first tooth 211 not arranged on the part of the turned-up edge 250 protruding relative to the boss 240 is arranged opposite to the part of the second tooth 221, which ensures the stability of the clamping of the first tooth 211 to the main shaft 100 and increases the contact area of the first tooth 211 and the second tooth 221 to the main shaft 100, and the sealing effect is better.

[0132] According to the photovoltaic support 10 provided in the embodiment of the present application, the first groove 260 is arranged between the first matching part 210 and the cover body 230, thereby improving the overall strength of the main shaft cover 200 structure, reducing the processing difficulty, and lowering the processing cost. The second tooth 221 is partially or wholly arranged opposite to the first groove 260, thereby increasing the contact area between the first tooth 211 and the second tooth 221 and the main shaft 100, and improving the sealing effect.

[0133] In some embodiments, the first matching part 210 and the second matching part 220 can be arranged in alignment.

[0134] It should be noted that, under the condition that the clamping stability of the first matching part 210 and the second matching part 220 to the main shaft 100 is met, the first matching part 210 and the second matching part 220 can be arranged in alignment.
