[0002] A photovoltaic mounting bracket is a fixed mounting bracket used to install a solar photovoltaic panel on a place with good lighting such as a roof. For the installation of existing photovoltaic panels, some are to fix the photovoltaic panel on the mounting bracket through bolts, but this often requires on-site measurement and drilling of the mounting bracket, resulting in low installation efficiency of the photovoltaic panel; currently, there are also some photovoltaic panels that are installed by sliding and installing multiple fasteners and fixing parts on the mounting bracket, fixing the mounting bracket on the installation platform through the fasteners, and locking and fixing the photovoltaic panel on the mounting bracket through the fixing parts. Then, through the cooperation of the fasteners, the mounting bracket, and the fixing parts, the installation and fixation of the photovoltaic panel are realized. However, when the fastener is damaged and needs to be replaced, it is necessary to slide and remove the fasteners, fixing parts, etc. previously installed on the mounting bracket in sequence before a new fastener can be replaced and installed. Moreover, some photovoltaic panels are relatively large in size, resulting in the need to install multiple fasteners and fixing parts on the photovoltaic panel to ensure the stability of the photovoltaic panel installation, but this is more likely to cause problems in the installation, replacement, and maintenance of the fasteners on the photovoltaic panel mounting bracket.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation manner:

[0022] In the description of this specification, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] As Figures 1 to 5 shown, this embodiment discloses a split fastener, including a fastener one 2 and a fastener two 3. A clamping block 31 is provided on the fastener two 3, and a clamping plate 21 adapted to the clamping block 31 is provided on the fastener one 2. A clamping groove 22 penetrating through the front and back is formed in the clamping plate 21, and the clamping groove 22 is adapted to the clamping block 31. The clamping block 31 can be slidably inserted into the clamping groove 22 in the front and back direction, that is, the clamping block 31 is slidably arranged in the clamping groove 22.

[0024] The clamping plate 21 is provided with a clamping strip 211 extending downward. The clamping strip 211 abuts against the outer side of the clamping block 31, and the lower end of the clamping strip 211 abuts downward against the fastener two 3. The clamping strip 211 restricts the lateral detachment of the clamping block 31 from the clamping plate 21 to ensure the stability of the cooperation between the fastener one 2 and the fastener two 3.

[0025] Further, a through hole 34 penetrating through the upper and lower parts is formed in the fastener two 3, and a mounting hole 25 corresponding to the position of the through hole 34 is formed in the clamping plate 21. The mounting hole 25 can be a threaded hole. The mounting hole 25 and the through hole 34 are distributed corresponding to each other in the up and down direction. An external bolt can be threadedly connected to the mounting hole 25 and penetrate downward through the through hole 34. By the external bolt, the relative front-back and left-right displacements of the fastener one 2 and the fastener two 3 are restricted, so as to fix and lock the fastener one 2 and the fastener two 3 together to improve the reliability of the cooperation between the fastener one 2 and the fastener two 3.

[0026] This embodiment also discloses a photovoltaic mounting bracket, which includes a split fastener, a water trough 1, a support plate 4, a pressing block 5, and a photovoltaic panel 6. The water troughs 1 are distributed below both sides of the photovoltaic panel 6. The water trough 1 is provided with side plates that slope upward on both sides. The water trough 1 is provided with sliding strips 11 distributed along the length direction. The first fastener 2 and the second fastener 3 are oppositely arranged on both sides of the water trough 1. The first fastener 2 and the second fastener 3 are installed on the sliding strip 11 through the cooperation of a clamping block 31 and a clamping groove 22 of a clamping plate 21.

[0027] The first fastener 2 and the second fastener 3 are respectively provided with a first sliding groove 24 and a second sliding groove 33 that are adapted to the sliding strip 11. The cooperation of the first sliding groove 24 and the second sliding groove 33 enables the first fastener 2 and the second fastener 3 to be installed on the sliding strip 11. When an external bolt penetrates downward through the through hole 34, it can abut against the sliding strip 11 to fix and limit the first fastener 2 and the second fastener 3 on the sliding strip 11, making the installation of the first fastener 2 and the second fastener 3 more convenient.

[0028] The first fastener 2 and the second fastener 3 are respectively provided with a first abutting foot 23 and a second abutting foot 32 located on both sides of the water trough 1. The cooperation of the first abutting foot 23 and the first fastener 2, and the second abutting foot 32 and the second fastener 3 limits the water trough 1. Further, the first abutting foot 23 and the second abutting foot 32 can be fixedly installed on the installation platform through external fixing screws to realize the cooperation of the first fastener 2 and the second fastener 3 to fix the water trough 1.

[0029] When it is necessary to replace the first fastener 2 and the second fastener 3, the external bolt can be first unscrewed to make the external bolt disengage from the installation hole 25 and the through hole 34, and the first fastener 2 and the second fastener 3 can be slid relative to each other back and forth to make the clamping block 31 and the clamping groove 22 disengage from each other, so that the first fastener 2 and the second fastener 3 can be quickly removed from the water trough 1 to realize the quick disassembly and replacement maintenance of the split fastener in this embodiment, making the use of the photovoltaic mounting bracket more convenient.

[0030] Moreover, compared with the traditional photovoltaic mounting bracket, when replacing a damaged fastener, it is necessary to first remove the fasteners, fixing parts and other components installed on the mounting bracket (i.e., the sliding strip 11 in this embodiment) in sequence before the fastener to be replaced can be replaced. In this embodiment, it is not necessary to disassemble components such as the support plate 4 installed on the sliding strip 11, and the fastener (i.e., the split fastener in this embodiment) can be quickly installed and replaced.

[0031] A support plate 4 is slidably arranged on the sliding strip 11. Specifically, the support plate 4 is provided with a T-shaped groove 42. The support plate 4 is slidably arranged on the sliding strip 11 through the T-shaped groove 42. A pressing block 5 is installed on the support plate 4. The pressing block 5 is connected to the support plate 4 through an external bolt and penetrates through the support plate 4 until it abuts against the sliding strip 11 to fix and limit the support plate 4 and the pressing block 5 on the sliding strip 11.

[0032] The pallet 4 is used to fix the photovoltaic panel 6. A pressing plate 51 is arranged on the pressing block 5 and abuts downward against the frame 61 of the photovoltaic panel 6. When the pressing block 5 is tightened on the pallet 4 by an external bolt, the pressing plate 51 of the pressing block 5 presses downward to fix the photovoltaic panel 6, and then the frame 61 of the photovoltaic panel 6 is pressed and fixed between the pallet 4 and the pressing block 5 to achieve the rapid installation of the photovoltaic panel 6.

[0033] Furthermore, the pallet 4 is provided with rib strips 41 on both sides of the frame 61 of the photovoltaic panel 6. The frame 61 is located between the two rib strips 41 on both sides, and the rib strips 41 are used to limit the position of the frame 61 to improve the stability of the installation of the frame 61 of the photovoltaic panel 6.

[0034] By sliding and adjusting the pallet 4 to a suitable position on the slide bar 11 and locking and fixing the pallet 4 on the slide bar 11 with an external bolt, and by cooperating the pallet 4 with the pressing block 5 to fix the photovoltaic panel 6, the rapid installation and fixation of the photovoltaic panel 6 can be achieved. At the same time, due to the slidable adjustment design of the pallet 4 on the slide bar 11, the corresponding installation positions of the pallet 4 and the pressing block 5 on the photovoltaic panel 6 can be adjusted in real time at the installation site to meet the use of photovoltaic panels 6 of different sizes, and the practicability is relatively good.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
