Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] The following combines Figures 1 to 5 to describe the embodiments of the present utility model.

[0038] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 5 shown, a photovoltaic bracket rotating bearing is provided, which includes a bearing seat 1, a bearing inner core 2 and a cable sheath 3. A circular through hole 101 is provided on the bearing seat 1. Two bearing inner cores 2 are movably installed in the circular through hole 101. A first installation groove 201 is provided on the side of the bearing inner core 2. The two first installation grooves 201 enclose a second through hole, and the second through hole is suitable for installing the main beam 4. The cable sheath 3 is detachably installed on the bearing inner core 2, and an installation cavity 301 is provided on the cable sheath 3, and the installation cavity 301 is suitable for installing a cable.

[0039] Specifically, as Figures 1 to 3 shown, in this embodiment, one side of the bearing seat 1 is arc-shaped and the other side is flat. A circular through hole 101 is provided in the middle of the bearing seat 1. The flat side of the bearing seat 1 is used for fixedly connecting with the photovoltaic bracket; as Figure 1 , Figure 2 and Figure 4 shown, the bearing inner core 2 is semi-circular, and its size is slightly smaller than half of the size of the circular through hole 101. The arc-shaped outer wall of the bearing inner core 2 matches the arc-shaped inner wall of the bearing seat 1. A first installation groove 201 is provided on the side of the bearing inner core 2 away from the arc-shaped outer wall. The two first installation grooves 201 on the two bearing inner cores 2 enclose a second through hole, and the bearing inner core 2 can rotate along the inner wall of the circular through hole 101 in the bearing seat 1; as Figure 1 and Figure 2As shown, the cable sheath 3 is detachably mounted on the bearing inner core 2, and the mounting cavity 301 on the cable sheath 3 is in the same direction as the extension direction of the main shaft.

[0040] In this embodiment, the shape of the first mounting groove 201 is not specifically limited. For example, in this example, the first mounting groove 201 is a rectangular groove, and two first mounting grooves 201 enclose a rectangular second through hole for mounting the rectangular main beam 4, and the size of the second through hole matches the outer shape of the rectangular main beam 4. In some other embodiments, the first mounting groove 201 can also be arc-shaped, and two arc-shaped first mounting grooves 201 enclose a circular second through hole for mounting the tubular main beam 4.

[0041] For the photovoltaic bracket rotating bearing in this embodiment, during use, first fix the bearing seat 1 on the support of the photovoltaic bracket, then place the two bearing inner cores 2 close to each other into the circular through hole 101, and then move the two bearing inner cores 2 away from each other so that they are in contact with the inner wall of the circular through hole 101. Subsequently, insert the main shaft into the second through hole and fixedly connect it to the bearing inner core 2. After the installation is firm, install the cable into the mounting cavity 301.

[0042] In the present utility model, a cable sheath 3 is detachably mounted on the bearing inner core 2, and the cable is installed in the mounting cavity 301 of the cable sheath 3. When the bearing inner core 2 rotates relative to the bearing seat 1, the cable sheath 3 can carry the cable and rotate together with the bearing inner core 2, thereby avoiding friction or jamming between the cable and the bearing seat 1.

[0043] In one embodiment, as Figure 5 shown, the cable sheath 3 includes a base 302 and a cover plate 303. The base 302 is detachably connected to the bearing inner core 2.

The cover plate 303 is movably mounted above the second mounting groove of the base 302. The mounting cavity 301 is enclosed between the cover plate 303 and the second mounting groove. During use, first open the cover plate 303, put the cable into the second mounting groove, and then connect the cover plate 303 to the base 302. The mounting cavity 301 can rotate together with the bearing inner core 2, avoiding friction between the cable and the bearing seat 1 when the bearing inner core 2 rotates, thereby achieving the protection of the cable.

[0045] The utility model adopts a structure in which the cover plate 303 is movably connected to the base 302, which facilitates the disassembly and assembly of the cable. The installation cavity 301 enclosed between the cover plate 303 and the second installation groove can protect the cable and prevent the cable from being damaged due to friction with the bearing seat 1.

The clamping groove 304 and the clamping buckle 305 are clamped together.

[0047] Specifically, in this embodiment, one side of the cover plate 303 is movably connected to the edge of one side of the second installation groove. For example, in this embodiment, the edge of the cover plate 303 and the second installation groove is an integrally formed flexible connection structure, so that the cover plate 303 can be covered or opened above the opening of the second installation groove; in some other embodiments, the cover plate 303 can also be hinged to the second installation groove by a hinge shaft.

[0048] In this embodiment, a transverse clamping groove 304 is provided outside the side of the second installation groove far from the movable connection with the cover plate 303. Correspondingly, a protruding clamping buckle 305 is provided at the bottom of the side of the cover plate 303 far from the movable connection with the second installation groove. The clamping buckle 305 and the clamping groove 304 are cooperatively clamped. A vertical groove 308 is provided at the bottom of the side of the cover plate 303 far from the movable connection with the second installation groove. When the clamping buckle 305 and the clamping groove 304 are cooperatively clamped, the top of the second installation groove is inserted into the groove 308, so as to realize the stable connection between the cover plate 303 and the second installation groove.

[0049] The cover plate 303 of the utility model and the second installation groove adopt a clamping method of the clamping groove 304 and the clamping buckle 305, which has the advantages of simple structure, convenient disassembly and assembly, and stable clamping.

[0052] In the present utility model, an appropriate gap is left between the bottom of the base 302 and the outer wall of the bearing housing 1. When the inner core 2 of the bearing rotates within the bearing housing 1, the base 302 can carry the cable and rotate synchronously with the inner core 2 of the bearing, thereby avoiding friction or jamming between the cable and the bearing housing 1.

[0053] In one embodiment, as Figure 5 shown, the mounting portion 306 includes two mutually facing convex ribs 307, and a groove 308 is provided between the two convex ribs 307. The convex ribs 307 are snap-fitted with the mounting holes 202.

When the mounting portion 306 is inserted into the mounting holes 202 from one side, the two convex ribs 307 are deformed by the restriction of the mounting holes 202 and move closer to the groove 308. After the mounting portion 306 is completely inserted into the mounting holes 202, the two convex ribs 307 return to their original positions and are snap-fitted and limited at the mounting holes 202, thereby ensuring that the mounting portion 306 is firmly installed; when it is necessary to disassemble the mounting portion 306, the operator squeezes the two convex ribs 307 so that they withdraw from the mounting holes 202, and the disassembly of the mounting portion 306 can be realized. The structure is simple and the operation is convenient.

[0055] In the present utility model, by providing two mutually facing convex ribs 307 on the mounting portion 306, when the mounting portion 306 is installed in the mounting holes 202, the two convex ribs 307 can be snap-fitted and limited with the mounting holes 202, making the installation of the base 302 on the inner core 2 of the bearing more stable.
