Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panels, and more particularly, to a fixing structure for photovoltaic panels. Background Art

[0002] Currently, the fixing structures of solar photovoltaic panels on the market are complex in structure and inconvenient to install.

[0003] In this regard, Chinese Patent Application No. CN201921721747.0 discloses a fixing structure for solar photovoltaic panels. This solution mainly involves opening fixing holes on an inclined plane, circular holes on the right side inside the notch, and connecting holes on the right wall surface of the baffle. Internal threads are provided on the inner walls of the fixing holes, circular holes, and connecting holes, and external threads are provided on the outer wall of the cylindrical rod. The cylindrical rod passes through the fixing holes, circular holes, and connecting holes and is threadedly connected. The photovoltaic panel is fixed to the inclined panel through concave blocks. In terms of installation and removal, the structure is simple and convenient for maintenance.

[0004] However, during the process of implementing the technical solution in the embodiments of this application by the utility model applicant of this application, it is found that the above technology has at least the following technical problems:

[0005] By using the rotation of the cylindrical rod to push the baffle, and then pressing the photovoltaic panel tightly in the concave block, the screwing connection method may become loose. Moreover, at least four fixed clamping points are required on one photovoltaic panel, so at least 4 tightenings are needed, and the operation is very inconvenient. Summary of the Utility Model

[0006] To make up for the above deficiencies, this application provides a fixing structure for photovoltaic panels, aiming to improve the problems mentioned in the above background art.

[0007] An embodiment of this application provides a fixing structure for photovoltaic panels, including the frame and bracket of the photovoltaic panel. Upper and lower clamping members are respectively installed on the upper and lower sides of the bracket. The upper clamping member is an insertion and rotation structure, and the lower clamping member is a spring pin structure.

[0008] In a specific implementation, the upper clamping member includes a rotating seat, and a socket is rotatably connected inside the rotating seat. A socket is provided on the socket that is adapted to the frame.

[0009] During the above implementation process, the photovoltaic panel is tilted. First, the upper end of the frame is inserted into the socket, and then the rear end drops down into the lower clamping member. The upper socket rotates with the frame. Therefore, the gap between the socket and the frame can be set very small or even without a gap. In this way, when the frame is fixed, the shaking can be effectively reduced.

[0010] In a specific implementation, a tension spring is provided between the rotating seat and the rotating seat.

[0011] In the above implementation process, the tension spring is used to keep the socket tilted in preparation for the frame to be inserted, so that during installation, there is no need to adjust the angle of each socket in advance, thereby simplifying the operation.

[0012] In a specific embodiment, the swivel seat is provided with an inclined surface adapted to the socket.

[0013] In the above implementation process, the inclined surface can help guide the frame into the socket. In this embodiment, the inclined surface and the inclined socket gas cylinder, the frame can be placed on the inclined surface and then directly slid into the socket, which is convenient for operation.

[0014] In a specific embodiment, the lower clamping member includes a base, and a locking tongue is elastically connected to the base.

[0015] In the above implementation process, when the upper frame of the photovoltaic panel is inserted into the socket, the lower frame falls down, pushes the lock tongue and falls on the base, and the lock tongue then pops out and gets stuck on the frame to complete the fixation. In this embodiment, after the frame is locked by the lock tongue, the edge of the frame is close to the base, which can prevent the frame from pushing the lock tongue back.

[0016] In a specific embodiment, a spring is provided between the locking tongue and the base.

[0017] In the above implementation process, the lock tongue utilizes the spring to maintain the tendency to pop outward, forming a spring pin structure.

[0018] In a specific embodiment, the rear end of the locking tongue is fixedly connected to a pull rod.

[0019] In the above implementation process, the pull rod facilitates the fingers to pull back the lock tongue to achieve unlocking, thereby realizing tool-free installation and removal of photovoltaic panels.

[0020] In a specific embodiment, mounting holes are provided on both the swivel seat and the base.

[0021] In the above implementation process, the swivel seat and the base are first installed and fixed on the bracket using the mounting holes. It should be noted that each photovoltaic panel requires two upper clamps and two lower clamps, which are located at the four corners of the photovoltaic panel respectively, so as to prevent the photovoltaic panel from shaking left and right.

[0022] Compared with the existing technology, the beneficial effect of the present application is: the upper frame of the photovoltaic panel is first inserted into the upper clamp, and then the lower frame falls into the lower clamp and is fastened by the spring pin structure. Since the upper clamp can be rotated, it can be tightly connected with the frame, which is beneficial to the stability of the fixation. Compared with the threaded fastening method, the present application realizes quick installation without tools, and there will be no looseness. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application.

[0030] Please refer to Figures 1 - 4 , the present application provides a photovoltaic panel fixing structure, including the frame 10 of the photovoltaic panel and the bracket 20. The upper and lower sides of the bracket 20 are respectively provided with an upper clamping member 30 and a lower clamping member 40. The upper clamping member 30 is an insertion and rotation structure, and the lower clamping member 40 is a spring pin structure. Among them, the upper frame 10 of the photovoltaic panel is first inserted into the upper clamping member 30, and then the lower frame 10 falls into the lower clamping member 40 and is locked by the spring pin structure. Since the upper clamping member 30 can rotate, it can be closely connected to the frame 10, which is beneficial to the stability of the fixation. Compared with the threaded fastening method, the present application realizes quick installation without tools and will not loosen.

[0031] Please refer to Figures 1 - 4 , the upper clamping member 30 includes a swivel base 31. A socket 32 is rotatably connected inside the swivel base 31, and a socket adapted to the frame 10 is provided on the socket 32. The photovoltaic panel is tilted. First, the upper frame 10 is inserted into the socket, and then the rear end falls into the lower clamping member 40. The upper socket 32 rotates along with the frame 10. Therefore, the gap between the socket and the frame 10 can be set very small or even without a gap. In this way, when the frame 10 is fixed, the shaking can be effectively reduced.

[0032] See also Figures 1 - 4 , a tension spring 33 is provided between the rotating seat 31 and the rotating seat 31. The tension spring 33 is used to keep the socket tilted in preparation for the frame 10 to be inserted, so that when installing, there is no need to adjust the angle of each socket 32 in advance, thereby simplifying the operation.

[0033] See also Figures 1 - 4 The swivel seat 31 is provided with an inclined surface 34 adapted to the socket. The inclined surface 34 can help guide the frame 10 into the socket. In this embodiment, the inclined surface 34 and the inclined socket cylinder, the frame 10 can be directly slid into the socket 32 after being placed on the inclined surface 34, which is convenient for operation.

[0034] See also Figures 1 - 4 The lower clamping member 40 includes a base 41, to which a locking tongue 42 is elastically connected. When the upper frame 10 of the photovoltaic panel is inserted into the socket 32, the lower frame 10 falls downward, pushing the locking tongue 42 aside and landing on the base 41. The locking tongue 42 then pops out and latches onto the frame 10, completing the fixation. In this embodiment, after the frame 10 is locked by the locking tongue 42, the edge of the frame 10 is close to the base 41, which can prevent the frame 10 from pushing the locking tongue 42 back.

[0035] See also Figures 1 - 4 A spring 43 is provided between the lock tongue 42 and the base 41. The lock tongue 42 utilizes the spring 43 to maintain a tendency to pop outwards, forming a spring pin structure.

[0036] See also Figures 1 - 4 The rear end of the lock tongue 42 is fixedly connected to a pull rod 44. The pull rod 44 facilitates the finger to pull the lock tongue 42 back to achieve unlocking, thereby achieving tool-free installation and removal of photovoltaic panels.

[0037] See also Figures 1 - 4 The swivel base 31 and the base 41 are both provided with mounting holes. The swivel base 31 and the base 41 are first mounted and fixed to the bracket 20 using the mounting holes. It should be noted that each photovoltaic panel requires two upper clamps 30 and two lower clamps 40, which are located at the four corners of the photovoltaic panel to prevent the photovoltaic panel from shaking left and right.

[0038] The working principle of this photovoltaic panel fixing structure is as follows: The bracket 20 is installed on the base at an inclined angle. The swivel base 31 and the base 41 are pre-installed and fixed on the bracket 20 using the mounting holes. The photovoltaic panel is tilted, and after the upper frame 10 is placed on the inclined surface 34, the photovoltaic panel is pulled backward. The frame 10 can directly slide into the socket 32. Then, the lower frame 10 of the photovoltaic panel drops downward, pushes open the locking tongue 42 and lands on the base 41. The locking tongue 42 then pops out and clamps on the frame 10 to complete the fixation. When the photovoltaic panel drops, the socket 32 can deflect along with the frame 10. Therefore, the socket 32 and the frame 10 can be closely matched, which is beneficial to the stability of installation. In summary, by first inserting the upper frame 10 of the photovoltaic panel into the upper clamping member 30, and then the lower frame 10 falling into the lower clamping member 40 and being locked by the spring pin structure. Since the upper clamping member 30 can rotate, it can be closely connected to the frame 10, which is beneficial to the stability of fixation. Compared with the threaded fastening method, this application realizes tool-free quick installation and will not loosen.
