Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, and in particular to a quick-locking structure for a photovoltaic bracket. Background Technology

[0002] Photovoltaic (PV) support structures are the structural frames that support PV modules (solar panels). They can fix PV modules in various locations such as rooftops, ground surfaces, and water surfaces, and their angles can be adjusted to maximize sunlight reception. In the construction of large-scale PV power plants, connecting the PV panel frames is a fundamental and highly repetitive task. If the connection is inconvenient, the installation of each PV panel will take more time, and it will be difficult to quickly disassemble and reconnect the frames, causing the PV system to be unable to adapt to changes in sunlight in a timely manner, thus reducing power generation efficiency.

[0003] A search of Chinese patent documents (authorization announcement number CN223007514U) reveals that this utility model belongs to the field of photovoltaic bracket technology, specifically relating to a quick-installation structure for a photovoltaic bracket. It includes two parallel first support rods, an adjustment assembly comprising a connecting plate, a pin plate, and a threaded post. A locking plate is fixedly connected to the bottom of the threaded post, and anti-slip protrusions are distributed on the locking plate to effectively prevent the connecting plate from sliding. The receiving component includes a receiving plate and a clamping component. A locking hole is provided through one side of the top of the clamping component to fix the second support rod between the clamping components. This device can meet basic usage requirements, but it is difficult to quickly disassemble and reconnect the frame, causing the photovoltaic system to be unable to adapt to changes in sunlight in a timely manner, thus reducing power generation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-locking structure for photovoltaic brackets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-locking structure for a photovoltaic bracket, comprising two connecting base plates for fixing, wherein a fixed mounting base plate is fixedly mounted on the top of one of the connecting base plates, and a movable mounting base plate is movably mounted on the top of the other connecting base plate, wherein a locking block for providing locking guidance is fixedly mounted on the top of the fixed mounting base plate. The locking block has two circular grooves inside, and a spring is connected inside each of the two circular grooves. A rotating rod is movably connected inside the locking block. One end of the spring is connected to the inner wall of the circular groove, and the other end of the spring is connected to the outer periphery of the rotating rod. Locking brackets for locking are installed at both ends of the rotating rod. Press plates for adjusting the locking brackets are installed at both ends of the locking brackets. The top of the press plates is provided with a pressing groove for easy operation by the operator.

[0006] Preferably, the top of the fixed mounting base plate is provided with a mating groove for entering with the pressing plate, and the top of the fixed mounting base plate is provided with a fixing bracket for support.

[0007] Preferably, the fixed frame is rotatably mounted on the side for adjustment, and the end of the movable frame away from the fixed frame is welded with a pressing handle for easy adjustment by the operator.

[0008] Preferably, the movable frame has two rotatably mounted hollow blocks, and the hollow blocks are movably connected to threaded posts for adjustment.

[0009] Preferably, the hollow block is provided with locking nuts on both sides for locking the length of the threaded post, and a U-shaped locking rod for quick locking is fixedly installed at one end of the threaded post.

[0010] Preferably, a locking hook plate for locking is fixedly installed on the top of the movable mounting base plate.

[0011] Preferably, a photovoltaic bracket mounting plate for fixing the photovoltaic bracket is installed on the side of the connecting substrate.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The quick-locking structure of this photovoltaic bracket benefits from the design of the locking frame. After fixing the pressing handle, releasing the pressing plate causes the rotating rod to automatically move closer to and lock the pressing handle under the restoring force of the spring, forming a reliable mechanical limit and ensuring a stable and secure connection between the U-shaped locking rod and the locking hook plate. To unlock, simply press the locking frame downwards to separate it from the pressing handle, quickly releasing the lock. This "automatic locking + convenient unlocking" design allows for rapid disassembly and reconnection of the frame while maintaining connection strength. It also enables the photovoltaic system to adjust its angle according to the season or time of day to match sunlight, improving power generation efficiency.

[0013] The quick-locking structure of this photovoltaic bracket benefits from the design of the locking nut and threaded post. The length of the threaded post within the hollow block can be adjusted to accommodate different installation gaps (adjustment range 0-50mm), reducing the requirements for installation precision. After the locking nut secures the threaded post, it works in conjunction with the locking bracket to lock the press handle, forming a dual guarantee of "rigid tension + mechanical anti-loosening." The structure's vibration resistance meets the IEC61215 standard, reducing the risk of loosening by 80% compared to traditional bolt connections, and significantly reducing the frequency of subsequent tightening and maintenance.

[0019] like Figures 1 to 5 The quick-locking structure of a photovoltaic bracket shown includes two connecting base plates 1 for fixing effect. A fixed mounting base plate 3 is fixedly installed on the top of one connecting base plate 1, and a movable mounting base plate 2 is movably installed on the top of the other connecting base plate 1. A locking block 4 for providing locking guidance is fixedly installed on the top of the fixed mounting base plate 3. The locking block 4 has two circular grooves 401 inside. The inner wall of the circular grooves 401 is coated with anti-rust lubricant to ensure that the spring 402 can return smoothly in an environment of -20℃ to 60℃. The spring 402 is connected inside the two circular grooves 401. The locking block 4 is movably connected to the rotating rod 403. One end of the spring 402 is connected to the inner wall of the circular groove 401, and the other end of the spring 402 is connected to the outer periphery of the rotating rod 403. Both ends of the rotating rod 403 are equipped with locking brackets 404 for locking. Both ends of the locking brackets 404 are equipped with pressing plates 405 for adjusting the locking brackets 404. The top of the pressing plate 405 is provided with a pressing groove 406 for easy operation. In the initial state, the connecting base plate 1 is fixed to the corresponding photovoltaic bracket through the photovoltaic bracket mounting plate 101. The two connecting base plates 1 support the fixed mounting base plate 3 and the movable mounting base plate 2 respectively. At this time, the spring 402 inside the locking block 4 is in a naturally contracted state, the rotating rod 403 is not under force, the locking frame 404 is in an open state, the pressing plate 405 has not entered the mating groove 407; the movable frame 302 has not been moved, and the U-shaped locking rod 305 is in a separated state from the locking hook plate 201.

[0020] The top of the fixed mounting base plate 3 is provided with a mating groove 407 for engaging with the pressing plate 405. A fixed bracket 301 for support is mounted on the top of the fixed mounting base plate 3. An adjustable movable bracket 302 is rotatably mounted on the side of the fixed bracket 301. A pressing handle 303 for easy adjustment by the operator is welded to the end of the movable bracket 302 away from the fixed bracket 301. Hollow blocks 304 are rotatably mounted on the two sides of the movable bracket 302. Adjustable threaded posts 307 are movably connected inside the hollow blocks 304. Locking threads are provided on both sides of the hollow blocks 304. The locking nut 306 is 307 in length. One end of the threaded post 307 is fixedly installed with a U-shaped locking rod 305 for quick locking. The U-shaped locking rod 305 is galvanized and the mating surface with the locking hook plate 201 is hardened to improve weather resistance and wear resistance. When locking is required, the operator first presses the handle 303 to move the movable frame 302 (the movable frame 302 rotates around the fixed frame 301), which drives the hollow block 304 and the threaded post 307 to move, so that the U-shaped locking rod 305 gradually approaches the locking hook plate 201 at the top of the movable mounting base plate 2. According to the actual spacing, the extension length of the threaded post 307 in the hollow block 304 can be adjusted by rotating the locking nut 306 to ensure that the U-shaped locking rod 305 can accurately hook the locking hook plate 201. After hooking, continue to pull down the pressing handle 303 to make the movable frame 302 rotate further. Through the rigid connection between the threaded post 307 and the hollow block 304, the pulling force is transmitted to pull the movable mounting base plate 2 towards the fixed mounting base plate 3 until the U-shaped locking rod 305 tightly hooks the locking hook plate 201 (at this time, the pressing handle 303 is in the pressed state). Then, the operator presses the pressing groove 406 on the top of the pressing plate 405 with both hands, so that the pressing plate 405 moves down along the mating groove 407, driving the rotating rod 403 to rotate in the locking block 4. At this time, the spring 402 in the circular groove 401 is twisted and stored by the rotating rod 403. The locking frame 404 rotates synchronously with the rotating rod 403 and tightens. After fixing the position of the pressing handle 303, the pressing plate 405 is released. The rotating rod 403 rotates in the opposite direction under the action of the return force of the spring 402. The locking frame 404 moves closer to the pressing handle 303 and finally locks the pressing handle 303. When it is necessary to unlock, press the locking frame 404 down. Since the locking frame 404 is separated from the pressing handle 303, the locking frame 404 will be released.

[0021] The top of the movable mounting base plate 2 is fixedly equipped with a locking hook plate 201 for locking. The side of the connecting base plate 1 is equipped with a photovoltaic bracket mounting plate 101 for fixing the photovoltaic bracket. The contact part between the locking bracket 404 and the pressing handle 303 adopts a toothed engagement structure. Even if the spring 402 experiences slight fatigue, the friction of the tooth surface can still prevent the pressing handle from being accidentally loosened. The connection between the photovoltaic bracket mounting plate 101 and the connecting base plate 1 is equipped with an anti-slip pad to prevent the bracket from shifting during the adjustment process. When adjusting the length of the threaded column 307, the locking nuts 306 on both sides must be loosened first. After the U-shaped locking rod 305 hooks the locking hook plate 201, one side nut is pre-tightened first, and then the length of the threaded column is finely adjusted to the optimal tension state. Finally, the other side nut is tightened. The operation sequence of thread adjustment is standardized to avoid connection deviation caused by uneven force.

[0022] Working principle In the initial state of this photovoltaic bracket's quick-locking structure, the connecting base plate 1 fixes the photovoltaic bracket via the photovoltaic bracket mounting plate 101, supporting the fixed mounting base plate 3 and the movable mounting base plate 2 respectively. The spring 402 inside the locking block 4 is in a stretched, stored state, causing the rotating rod 403 to rotate under tension. The locking frame 404 approaches the pressing handle 303, and the pressing plate 405 is pressed into the mating groove 407 to restrict rotation. The U-shaped locking rod 305 separates from the locking hook plate 201. During locking, the operator operates the pressing handle 303, causing the movable frame 302 to rotate around the fixed frame 301, moving the hollow block 304 and the threaded post 307, bringing the U-shaped locking rod 305 closer to the locking hook plate 201. The locking nut 306 is rotated to adjust the length of the threaded post 307 for precise hooking. Continue to operate the pressing handle 303. The movable frame 302 rotates and tightens the movable mounting base plate 2 through the rigid connection until the U-shaped locking rod 305 is tightly engaged with the locking hook plate 201. The pressing handle 303 is in the pressed fixed position. Then, release the pressing plate 405, which pops out of the mating groove 407 under the elastic force of the spring 402. The rotating rod 403 rotates in the opposite direction, causing the locking frame 404 to approach and engage with the pressing handle 303, forming a lock to prevent loosening. Tighten the locking nut 306 to fix the threaded post 307, completing the final locking. To unlock, loosen the locking nut 306, press down the locking frame 404 to make the pressing plate 405 enter the mating groove 407, and the rotating rod 403 overcomes the elastic force to separate the locking frame 404 from the pressing handle 303. Turn the handle in the opposite direction to make the U-shaped locking rod 305 disengage from the locking hook plate 201, and the structure resets.
