[0035] In addition, in the description of this application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between related objects.

[0036] The cable clamp of this application is fixed on the main shaft of the photovoltaic bracket through the annular part and the abutting part, so that the cable clamp is not easily detached during the rotation of the main shaft; the cable clamp is provided with a clamping part for clamping the cable, so as to fix the cable extending from the photovoltaic panel outside the main shaft, which is not only convenient for maintenance, but also has no influence on the structure of the photovoltaic bracket itself, does not damage the column, and does not generate an additional load on the column.

[0037] As Figures 1 to 4 shown, this application provides an embodiment of a cable clamp, including an annular part 10, an abutting part 20, and a clamping part 30. The annular part 10 is provided with an opening, and the cable clamp 100 is clamped on the main shaft 200 through the opening; the abutting part 20 is connected to the opening of the annular part 10, and the abutting part 20 is used to abut against the main shaft 200 to prevent detachment; the clamping part 30 is connected to the abutting part 20 and extends, and the clamping part 30 presses the cable 300 against the main shaft 200 through elasticity.

[0038] Specifically, the annular part 10 is provided with an opening to facilitate sleeving the annular part 10 on the main shaft 200; the annular part 10 includes a body part and two free ends provided on the body part, namely a first free end and a second free end. The body part forms a groove-like structure for clamping the main shaft 200, and the opening is formed between the first free end and the second free end; the inner contour of the annular part 10 is adapted to the outer contour of the main shaft 200, so that the inner wall of the annular part 10 can fit with the outer wall of the main shaft 200, improving the friction between the annular part 10 and the main shaft 200, and further improving the connection firmness between the annular part 10 and the main shaft 200. Figure 3The shapes of the middle main shaft 200 and the annular part 10 are only one example. In this embodiment, the outer contour shape of the main shaft 200 and the inner contour shape of the annular part 10 are not limited. The cable clip 100 of this embodiment can be applied to main shafts 200 with different shapes. Exemplarily, the outer contour shape of the main shaft 200 can be circular, oval, semi-circular or polygonal, etc. Polygons include quadrilaterals (rectangles), pentagons, hexagons, etc. The inner contour shape of the annular part 10 is the same as the outer contour shape of the main shaft 200, that is, the inner contour shape of the annular part 10 can also be circular, oval, semi-circular or polygonal, etc. In this embodiment, the annular part 10 at least surrounds a part of the main shaft 200. Exemplarily, when the outer contour of the main shaft 200 is rectangular, the annular part 10 surrounds three faces of the main shaft 200, and the annular part 10 forms an opening below the main shaft 200 to facilitate sleeving the cable clip 100 on the main shaft 200 at the opening. The size of the area where the annular part 10 surrounds the main shaft 200 is not specifically limited in this embodiment. In actual application, it is based on the convenience of installing the cable clip 100 and being able to stably fix it on the main shaft 200.

[0039] The abutting part 20 is connected to the opening of the annular part 10. When the annular part 10 is sleeved on the main shaft 200, the abutting part 20 abuts against the main shaft 200, so that the entire cable clip 100 clamps the main shaft 200, and further makes the cable clip 100 not easily fall off during the rotation of the main shaft 200. The clamping part 30 is connected to the abutting part 20 and extends. The clamping part 30 can press the cable 300 against the outside of the main shaft 200 through elasticity to fix the cable 300 and facilitate the detection and maintenance of the cable 300.

[0040] At least one of the two free ends of the annular part 10 is provided with an abutting part 20 to form a constricted shape. In one example, only one free end of the annular part 10 is provided with an abutting part 20, and the clamping part 30 is connected to the abutting part 20, which can also realize the fixation of the cable clip 100 and the main shaft 200 and the fixation of the cable 300. For example, a first abutting part 21 and a first clamping part 31 can be provided at the first free end of the annular part 10, or a second abutting part 22 and a second clamping part 32 can be provided at the second free end of the annular part 10.

[0041] In another example, abutting portions 20 are respectively provided at two free ends of the annular portion 10, and the clamping portions 30 are arranged in one-to-one correspondence with the abutting portions 20, that is, each abutting portion 20 is respectively connected to a clamping portion 30. The two abutting portions 20 are respectively a first abutting portion 21 and a second abutting portion 22, and the two clamping portions 30 are respectively a first clamping portion 31 and a second clamping portion 32. The first end of the first abutting portion 21 is fixedly connected to the first free end of the annular portion 10, and the second end of the first abutting portion 21 extends towards the direction of the main shaft 200 and is used for abutting against one side of the main shaft 200; the first end of the second abutting portion 22 is fixedly connected to the second free end of the annular portion 10, and the second end of the second abutting portion 22 extends towards the direction of the main shaft 200 for abutting against the other side of the main shaft 200. The first clamping portion 31 is arranged on one side of the annular portion 10 and is fixedly connected to the second end of the first abutting portion 21, and is used for pressing the cable 300 against the main shaft 200 by elastic force; the second clamping portion 32 is arranged on the other side of the annular portion 10 and is fixedly connected to the second end of the second abutting portion 22, and is used for pressing the cable 300 against the main shaft 200 by elastic force.

[0042] In this embodiment, the two free ends of the annular portion 10 extend along the direction of approaching each other to form the first abutting portion 21 and the second abutting portion 22. When the annular portion 10 is sleeved on the main shaft 200, by abutting the first abutting portion 21 and the second abutting portion 22 against the bottom of the main shaft 200, the entire cable clamp 100 can be stuck to the main shaft 200, and the cable clamp 100 is not easily detached during the rotation of the main shaft 200. The first clamping portion 31 and the second clamping portion 32 are respectively located on both sides of the annular portion 10, that is, the first clamping portion 31 and the second clamping portion 32 are respectively located on both sides of the main shaft 200. The first clamping portion 31 and the second clamping portion 32 can respectively clamp the cable 300 to fix the cable 300 on both sides of the main shaft 200, realizing the fixation of the cable 300 and facilitating the inspection and maintenance of the cable 300.

[0043] In another example, abutting portions 20 are respectively provided at two free ends of the annular portion 10, but only one abutting portion 20 is connected to a clamping portion 30. The clamping portion 30 is located on one side of the annular portion 10, that is, the clamping portion 30 is located on one side of the main shaft 200, so as to fix the cable 300 on one side of the main shaft 200. It can also realize the fixation of the cable 300 and the main shaft 200, and facilitate the inspection and maintenance of the cable 300.

[0044] In some embodiments, as Figure 1 and Figure 2 shown, the first abutting portion 21 includes a first bent portion 211 with an opening. One end of the first bent portion 211 is fixedly connected to the first free end of the annular portion 10, and the other end of the first bent portion 211 is fixedly connected to the first clamping portion 31 and abuts against the main shaft 200.

[0045] The second abutting portion 22 includes a second bending portion 221 having an opening. One end of the second bending portion 221 is fixedly connected to the second free end of the annular portion 10, and the other end of the second bending portion 221 is fixedly connected to the second clamping portion 32 and abuts against the main shaft 200.

[0046] In this embodiment, the first free end of the annular portion 10 first extends towards the main shaft 200 and then bends away from the main shaft 200 to form a first bending portion 211. The second free end of the annular portion 10 first extends towards the main shaft 200 and then bends away from the main shaft 200 to form a second bending portion 221. The first bending portion 211 is used to connect the first free end of the annular portion 10 and the first clamping portion 31, and the second bending portion 221 is used to connect the second free end of the annular portion 10 and the second clamping portion 32. At the lower opening of the annular portion 10, the first bending portion 211 and / or the second bending portion 221 are respectively bent inward. When the annular portion 10 is sleeved on the main shaft 200, the first bending portion 211 and / or the second bending portion 221 are respectively located below the main shaft 200 and abut against the bottom of the main shaft 200, so as to fix the cable clamp 100 on the main shaft 200, and it is not easy to fall off when the main shaft 200 rotates. In this embodiment, the first bending portion 211 and / or the second bending portion 221 generate elastic force to press the cable 300 against the main shaft 200. In other embodiments, the cable 300 is pressed against the main shaft 200 by the elastic force of the clamping portion 30 itself.

[0047] Furthermore, as Figure 2 shown, the two ends of the first bending portion 211 are not coplanar, so that the first clamping portion 31 and the annular portion 10 are located on different planes. The two ends of the second bending portion 221 are not coplanar, so that the second clamping portion 32 and the annular portion 10 are located on different planes. That is, the first clamping portion 31 and the annular portion 10 are located on different cross-sections of the main shaft 200, and the second clamping portion 32 and the annular portion 10 are also located on different cross-sections of the main shaft 200. This not only facilitates the arrangement of the first clamping portion 31 and the second clamping portion 32 and avoids interference between the first clamping portion 31, the second clamping portion 32 and the annular portion 10, but also when clamping the cable 300, the outside of the annular portion 10 can abut against the cable 300 at one position of the cable 300, while the first clamping portion 31 or the second clamping portion 32 can clamp another position of the cable 300. That is, when clamping the cable 300, forces are applied to the cable 300 at two different positions to more stably fix the cable 300 and reduce the movement of the cable 300. In addition, the two clamping points can distribute the pressure on the cable 300 more evenly when clamping the cable 300, avoid excessive pressure at a single point, and reduce the risk of cable 300 damage.

[0048] Further, when the abutting portion 20 is provided at only one free end of the annular portion 10, if the first abutting portion 21 is provided at the first free end of the annular portion 10, the distance between the first bending portion 211 of the first abutting portion 21 and the second free end of the annular portion 10 is less than the maximum width of the main shaft 200; if the second abutting portion 22 is provided at the second free end of the annular portion 10, the distance between the second bending portion 221 of the second abutting portion 22 and the first free end of the annular portion 10 is less than the maximum width of the main shaft 200. When the abutting portions 20 are provided at the two free ends of the annular portion 10 respectively, as Figure 3 shown, the minimum distance between the first bending portion 211 of the first abutting portion 21 and the second bending portion 221 of the second abutting portion 22 is less than the maximum width of the main shaft 200, which can improve the connection stability between the cable clamp 100 and the main shaft 200 and prevent the cable clamp 100 from falling off the main shaft 200 during normal use.

[0049] In some embodiments, the abutting portion 20 further includes an inclined section, the inclined section is arranged between the annular portion 10 and the bending portion, one end of the inclined section is fixedly connected to the free end of the annular portion 10, and the other end of the inclined section is fixedly connected towards the bending portion.

[0050] As Figure 1 and Figure 3 shown, the first abutting portion 21 further includes a first inclined section 212, the first inclined section 212 is arranged between the annular portion 10 and the first bending portion 211, one end of the first inclined section 212 is fixedly connected to the first free end of the annular portion 10, and the other end of the first inclined section 212 is inclined towards the second abutting portion 22 and fixedly connected to the first bending portion 211.

[0051] As Figure 1 and Figure 3 shown, the second abutting portion 22 further includes a second inclined section 222, the second inclined section 222 is arranged between the annular portion 10 and the second bending portion 221, one end of the second inclined section 222 is fixedly connected to the second free end of the annular portion 10, and the other end of the second inclined section 222 is inclined towards the first abutting portion 21 and fixedly connected to the second bending portion 221.

[0052] In this embodiment, by providing the first inclined section 212 and the second inclined section 222, and the first inclined section 212 and the second inclined section 222 are respectively tightened towards the main shaft 200, the connection stability between the cable clamp 100 and the main shaft 200 is further improved, the cable clamp 100 is prevented from falling off the main shaft 200, and when the first bending portion 211 and the second bending portion 221 respectively stably abut against the bottom of the main shaft 200, the diameters of the first bending portion 211 and the second bending portion 221 can be reduced, thereby reducing the volume of the cable clamp 100, saving materials and reducing costs.

[0053] In some embodiments, asFigure 1 and Figure 3 As shown in Figure 3 , the first clamping portion 31 includes a first clamping section 311 and a first limiting section 312. One end of the first clamping section 311 is fixedly connected to the first abutting portion 21. The other end of the first clamping section 311 extends away from the first abutting portion 21 and is fixedly connected to one end of the first limiting section 312. The first limiting section 312 is arc-shaped and the convex portion 313 faces the main shaft 200.

[0054] The lower end of the first clamping section 311 is fixedly connected to the first bending portion 211, and the upper end of the first clamping section 311 is fixedly connected to the first limiting section 312. The first clamping section 311 is inclined and forms a certain angle with the vertical direction. When the cable clamp 100 is fixed on the main shaft 200, a triangular area a can be formed between the first clamping section 311 and the side of the annular portion 10. This triangular area a is used to place the cable 300, and the spatial size of this triangular area a can be adjusted. If there are more cables 300 to be hung, the first clamping section 311 can be expanded away from the main shaft 200 to increase the angle between the first clamping section 311 and the vertical direction, thereby increasing the space of the above triangular area a.

[0055] The upper end of the first clamping section 311 is bent towards the main shaft 200 to form the first limiting section 312. The first limiting section 312 is arc-shaped and the convex portion 313 faces the main shaft 200. When the cable 300 is clamped in the above triangular area a, the convex portion 313 of the first limiting section 312 can block the cable 300 to prevent the cable 300 from falling out of the triangular area a during the rotation of the main shaft 200, playing a role in limiting the cable 300. Setting the first limiting section 312 as arc-shaped and using the convex portion 313 for limiting can facilitate the installation of the cable 300 in the triangular area a formed by the first clamping section 311. In this embodiment, the size of the convex portion 313 formed by bending the first limiting section 312 towards the main shaft 200 can be set according to the distance between the upper end of the first clamping section 311 and the side of the annular portion 10 to achieve the purpose of preventing the cable 300 from falling during the rotation of the main shaft 200. In other embodiments, the first limiting section 312 may not be arc-shaped, and the first limiting section 312 may be a straight line segment bent towards the main shaft 200, which can also achieve the limiting effect on the cable 300.

[0056] In some embodiments, such as Figure 1 and Figure 3As shown in the figure, the second clamping part 32 includes a second clamping section 321 and a second limiting section 322. One end of the second clamping section 321 is fixedly connected to the second abutting part 22, and the other end of the second clamping section 321 extends away from the second abutting part 22 and is connected to one end of the second limiting section 322. The second limiting section 322 is arc-shaped and the convex part 323 faces the main shaft 200. The structure and function of the second clamping part 32 in this embodiment are the same as those of the first clamping part 31, and the same parts will not be described in detail here. In other embodiments, the structure of the second clamping part 32 may also be different from that of the first clamping part 31. For example, the first clamping section 311 of the first clamping part 31 is a straight section, and the second clamping section 321 of the second clamping part 32 is not a straight section but a wavy section; or, the first clamping section 311 of the first clamping part 31 is a wavy section, while the second clamping section 321 of the second clamping part 32 is a straight section; or the first limiting section 312 of the first clamping part 31 is arc-shaped, while the second limiting section 322 of the second clamping part 32 is a straight section bent towards the main shaft 200, which can also play a role in limiting the cable 300.

[0057] In some embodiments, the annular part 10, the abutting part 20, and the clamping part 30 are integrally formed. In this embodiment, the material of the cable clamp 100 can be steel wire. During manufacturing, the steel wire can be bent by a bending machine to form the annular part 10, the abutting part 20, and the clamping part 30 respectively. The production cost is low and the manufacturing process is simple. It can be processed in a factory or manufactured on site.

[0058] This application also provides an embodiment of a photovoltaic bracket, as Figures 1 to 4 shown, including a main shaft 200 and the cable clamp 100 described in any of the above embodiments. The cable clamp 100 is fixedly arranged on the main shaft 200, and a plurality of cable clamps 100 can be axially fixed on the main shaft 200 to fix the cable 300 at different positions of the cable 300. At the construction site, after the main shaft 200 is installed, a suitable position can be selected on the main shaft 200. First, open the annular part 10 of the cable clamp 100 a little, put it on from above the main shaft 200, and then loosen the annular part 10 to make the annular part 10 return to its original state. It is also possible to directly put the cable clamp 100 into the main shaft 200 from the end face of the main shaft 200, and then move the cable clamp 100 to a suitable position on the main shaft 200. After installing the cable clamp 100, finally place the cable 300 into the clamping part 30 of the cable clamp 100 from above. In this embodiment, the cable 300 is fixed on both sides of the main shaft 200, which is convenient for the inspection and maintenance of the cable 300.

[0059] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0060] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
