DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example: Refer to Figure 1-Figure 4 , a connection structure for a photovoltaic module frame, comprising:

[0035] The rotating shaft 2 is configured to be rotatably matched with the photovoltaic module frame 1;

[0036] The card plate 3 is fixed on the rotating shaft 2. The card plate 3 has a switchable first fixed position and a second fixed position through the rotating shaft 2. When the card plate 3 is in the first fixed position, the card plate 3 can abut against the photovoltaic component to fix the photovoltaic component in the photovoltaic component frame 1. When the card plate 3 is in the second fixed position, the photovoltaic component is movably connected to the photovoltaic component frame 1.

[0037] The control component includes a locking bolt 4 inserted into the rotating shaft 2, with both ends of the locking bolt 4 passing through the rotating shaft 2. The locking bolt 4 is configured to be threadedly connected to the photovoltaic component frame 1 to form a switchable loosening / tightening state, wherein the rotating shaft 2 is fixed relative to the photovoltaic component frame 1 only when the locking bolt 4 is in the tightening state.

[0038] The utility model utilizes a rotating shaft 2 that is rotatably connected to the photovoltaic component frame 1, and a card plate 3 is fixedly installed on the rotating shaft 2, so that the card plate 3 can be rotated relative to the photovoltaic component frame 1 through the rotating shaft 2, and the first fixed position and the second fixed position are respectively defined for the card plate 3. At the same time, in the first fixed position, the photovoltaic component is fixed in the installation groove of the photovoltaic component frame 1 through the card plate 3, and in the second fixed position, the photovoltaic component is movably connected to the photovoltaic component frame 1, which is convenient for regulating the loading and unloading of the photovoltaic component, thereby improving the construction efficiency. In addition, the locking bolt 4 inserted in the rotating shaft 2 has a tightening and loosening state relative to the photovoltaic component frame 1. When it is in the tightening state, the card plate 3 is fixed relative to the photovoltaic component frame 1 through the rotating shaft 2, thereby ensuring that the card plate 3 is effectively fixed in the first fixed position or the second fixed position, thereby improving the integrity of the photovoltaic component connection structure, and when it is in the loosening state, the card plate 3 rotates relative to the photovoltaic component frame 1 through the rotating shaft 2, which is convenient for switching the first fixed position and the second fixed position of the card plate 3, thereby improving the efficiency of disassembly and assembly of the photovoltaic component.

[0039] Furthermore, it also includes:

[0040] The first limiting ring 5 is sleeved and fixedly connected to the part of the locking bolt 4 located inside the rotating shaft 2. The inner wall surface of the rotating shaft 2 is provided with a first limiting groove. When in the tightened state, the first limiting ring 5 abuts against the first limiting groove. When in the loosened state, the first limiting ring 5 slides in cooperation with the first limiting groove.

[0041] By passing the locking bolt 4 through the rotating shaft 2 and slidingly connecting the first limiting ring 5 fixed to the locking bolt 4 with the first limiting groove provided in the rotating shaft 2, the connection stability between the locking bolt 4 and the rotating shaft 2 is ensured. At the same time, when the locking bolt 4 is switched between tightening and loosening, the connection state between the first limiting ring 5 and the first limiting groove can be correspondingly converted between relative fixed connection and sliding contact, and then by changing the connection state between the rotating shaft 2 and the photovoltaic component frame 1, the fixed position and fixed state of the clamping plate 3 are regulated, thereby improving work efficiency.

[0042] Furthermore, it also includes:

[0043] The rubber ring 6 has an embedding groove at the top of the rotating shaft 2. The embedding groove is an annular structure. The rubber ring 6 is sleeved in the embedding groove and is configured so that its two ends are in contact with the rotating shaft 2 and the locking bolt 4 respectively.

[0044] By opening a groove at the top of the rotating shaft 2, the rubber ring 6 embedded in the groove is in contact with the rotating shaft 2 and the locking bolt 4, so as to provide a damping effect during the rotation of the locking bolt 4. When the locking bolt 4 is tightened to fix the clamping plate 3 to the photovoltaic component frame 1, the connection stability is improved to ensure the fixing effect of the photovoltaic component.

[0045] Furthermore, it also includes:

[0046] The gasket 7 is sleeved on the rotating shaft 2, and the two ends are configured to respectively engage the clamping plate 3 and the photovoltaic module frame 1 in sliding contact.

[0047] The gasket 7 is made of metal, is sleeved on the rotating shaft 2 and rotates relative to the rotating shaft 2. The gasket 7 is used to reduce the friction between the card plate 3 and the photovoltaic component frame 1, so as to facilitate the adjustment of the card plate 3 to the first fixed position or the second fixed position.

[0048] In one embodiment of the present technical solution, referring to Figure 4, the gasket 7 is sleeved and fixed on the rotating shaft 2, and a through hole is opened on the side of the gasket 7 away from the card board 3, and positioning grooves 13 are opened on the photovoltaic component frame 1 at two points where the card board 3 is in the first fixed position and the second fixed position, respectively. By sliding a positioning pin 12 through the through hole, after the card board 3 is moved to the first fixed position or the second fixed position, the positioning pin 12 and the adjacent positioning groove 13 are used to fix the gasket 7 together with the rotating shaft 2, thereby improving the fixing effect on the card board 3.

[0049] Furthermore, it also includes:

[0050] The second limiting ring 8 is sleeved on the portion of the rotating shaft 2 extending into the photovoltaic component frame 1. The second limiting ring 8 is fixedly connected to the rotating shaft 2. The second limiting ring 8 is configured to be fixed relative to the photovoltaic component frame 1 in a tightened state, and to be in limited sliding connection with the photovoltaic component frame 1 in a loosened state.

[0051] By sleeved and fixedly connected with the second limit ring 8 on the rotating shaft 2, and the second limit ring 8 is arranged in the photovoltaic component frame 1 and in sliding contact with the photovoltaic component frame 1, the connection stability between the rotating shaft 2 and the photovoltaic component frame 1 is improved, and when the locking bolt 4 is tightened, the locking locking bolt 4 squeezes the rotating shaft 2, and the second limit ring 8 and the second limit groove are abutted against each other, so that the fixing between the rotating shaft 2 and the photovoltaic component frame 1 is achieved, and the control effect of the movement state of the clamping plate 3 is further enhanced.

[0052] Furthermore, it also includes:

[0053] The clamping ring 9 is sleeved and fixedly connected to the part of the rotating shaft 2 outside the photovoltaic module frame 1. The outer peripheral side of the clamping ring 9 is provided with a tooth groove, and one side of the clamping plate 3 is provided with a clamping groove, and the clamping ring 9 is clamped in the clamping groove.

[0054] By fixing a retaining ring 9 on the outer peripheral side of the rotating shaft 2 and providing a tooth groove on the retaining ring 9, when the retaining plate 3 is fixed to the rotating shaft 2 through the retaining ring 9, the retaining ring 9 is directly engaged in the retaining groove, maintaining the relative fixed stability between the retaining plate 3 and the rotating shaft 2, making it easy to adjust the rotation state of the rotating shaft 2 through the locking bolt 4, and to adjust the rotation or fixation of the retaining plate 3.

[0055] Furthermore, it also includes:

[0056] The friction layer 10 is fixedly connected to a side of the card plate 3 close to the photovoltaic component frame 1. When the card plate 3 is located at the first fixed position, the friction layer 10 is configured to abut against the photovoltaic component.

[0057] Furthermore, at least two pairs of rotating shafts 2 are provided, and the two pairs of rotating shafts 2 are respectively arranged on opposite sides of the photovoltaic component frame 1 .

[0058] The friction layer 10 is made of common sponge or rubber material. It can be understood that by making the thickness of the friction layer 10 greater than the thickness of the gasket 7, the contact and fixing effect of the card plate 3 and the photovoltaic component can be effectively guaranteed under the premise that the gasket 7 raises the card plate 3, and by evenly distributing a number of rotating shafts 2 around the photovoltaic component frame 1, as well as the corresponding card plates 3 and locking bolts 4, the fixing effect on the photovoltaic component is further enhanced.

[0059] Furthermore, it also includes:

[0060] The identification strip 11 is fixed to the top of the locking bolt 4 and is used to mark the direction in which the locking bolt 4 is switched to the tightening state, thereby improving the efficiency of adjusting the locking bolt 4 and further speeding up the efficiency of disassembling and assembling the photovoltaic module.

[0061] A photovoltaic module frame comprises any one of the above-mentioned connection structures for photovoltaic module frames.

[0062] The working process of this embodiment is as follows:

[0063] By rotating the locking bolt 4 in the opposite direction along the identification strip 11, the rotating shaft 2 is rotated relative to the photovoltaic component frame 1 when the locking bolt 4 is loosened. When the rotating card plate 3 extends into the first fixed position above the groove in the vertical direction, the locking bolt 4 is rotated in the direction of the identification strip 11, and the first limiting ring 5 is abutted against the rotating shaft 2, and the second limiting ring 8 is abutted against the photovoltaic component frame 1, so that the rotating shaft 2 is fixed, and the card plate 3 is fixed together, and the photovoltaic component and the photovoltaic component frame 1 are fixed in cooperation with the friction layer 10 to achieve the installation of the photovoltaic component. When the photovoltaic component needs to be disassembled, the locking bolt 4 is loosened, and the card plate 3 is rotated to be parallel to one side of the connected photovoltaic component frame 1, that is, in the second fixed position, the card plate 3 does not block the photovoltaic component in the vertical direction, so that it is convenient for personnel to remove the photovoltaic component and improve construction efficiency.
