Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-stability purlin connector for a photovoltaic support. Background Art

[0002] In photovoltaic power generation systems, photovoltaic racks are a crucial component, not only supporting the photovoltaic panels but also directly impacting the stability and safety of the entire system. Purlin connectors, a key component in photovoltaic rack systems, connect the purlins to the main rack, ensuring the photovoltaic panels are securely mounted on the racks. They also withstand various environmental factors, such as wind loads, snow loads, and temperature fluctuations.

[0003] Existing purlin connectors for photovoltaic racks are typically made of metal materials such as aluminum alloy or steel. Their design includes a connector body, a locking device, and an adjustment mechanism. The connector body, typically a U- or C-shaped steel channel, secures the purlins; locking devices such as bolts and nuts secure the connector to the main rack.

[0004] Although the current purlin connectors have met the needs of photovoltaic brackets to a certain extent, there are still some problems that need to be optimized in actual applications. The existing connectors are difficult to distribute the force, and the connection points are prone to loosening and damage. After the existing connectors fix the two ends of the purlin, it is difficult to adjust the angle of the purlin, resulting in limited installation methods. It needs to be disassembled and then adjusted, which is more cumbersome in actual application. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-stability purlin connector for a photovoltaic bracket.

[0006] The technical solution of the present utility model is a high-stability purlin connector for a photovoltaic bracket: it includes a shell with openings on both sides, and two fixing members rotatably arranged in the openings in a one-to-one manner; the fixing members are rotatably connected to the shell through a shaft; a locking block for locking the rotation of the shaft is slidably provided in the fixing member, and the locking block is connected to the fixing member through a first spring, and the fixing member is provided with a pin hole for plugging into the corresponding purlin.

[0007] Description: The design of the pin hole matches the sandalwood bar, which improves the versatility and adaptability of the connector and is suitable for the construction of photovoltaic brackets in various scenarios. The locking block and the shaft rod are locked together, which not only improves the stability and reliability of the photovoltaic bracket, but also simplifies the installation process and reduces maintenance costs.

[0008] Furthermore, both ends of the shaft are fixedly connected to the housing, and the shaft passes through and is rotatably connected to the fixing member; a plurality of vertical grooves are circumferentially provided on the surface of the shaft, and a plurality of vertical teeth that can be correspondingly engaged with the vertical grooves are provided on the locking block.

[0009] Description: The precise fit between the vertical teeth and the vertical slots forms a physical snap-in connection of multiple plug-in locks, which greatly enhances the locking effect of the locking block on the shaft, ensuring the stability of the fixing on the shell, and is not easy to loosen even under the action of external forces. The matching design of the vertical teeth and the vertical slots also provides multiple positioning points, making the position adjustment of the fixing more precise and easy to align with the required angle, thereby improving the adaptability of the photovoltaic bracket. Since the matching principle of the vertical teeth and the vertical slots is intuitive and clear, it becomes easier to check and adjust the locking state during operation and maintenance.

[0010] Furthermore, a protrusion is fixedly provided on the surface of the fixing member via a second spring, and a plurality of grooves capable of correspondingly engaging with the protrusion are provided on the housing.

[0011] Description: The design of the bumps and grooves can easily adjust the position of the fixings and assist in positioning the angle of the fixings to determine the optimal angle required for installing the connecting purlins, thereby improving installation efficiency. When the angle needs to be adjusted, only appropriate pressure is required to complete the re-locking after the position change. The operation is simple and quick, and it is convenient to adjust the angle between the purlins.

[0012] Furthermore, a first magnetic block is provided on the surface of the fixing member, and a plurality of second magnetic blocks capable of magnetically attracting the first magnetic block are provided on the shell along the rotation track of the fixing member.

[0013] Note: The magnetic attraction between the first and second magnetic blocks provides additional positioning and preliminary locking functions for the fixings to determine the optimal angle required to connect the purlins, thereby improving installation efficiency.

[0014] Furthermore, a gasket for shockproofing is provided on the contact surface between the shell and the fixing member.

[0015] Description: The gasket can absorb and disperse the vibration energy from the fixing parts or the outside world, effectively protecting the connecting parts from vibration damage, reducing the wear between the housing and the fixing parts, and extending the service life of both.

[0016] The beneficial effects of the utility model are:

[0017] The utility model realizes multi-angle adjustment of the purlin connection through the rotation connection of the fixing part and the shell, and the angle can be adjusted after fixation. The purlin connection angle can be adjusted as needed in different seasons or after changes in sunlight, which can maximize the capture of light energy, thereby improving the photoelectric conversion efficiency and overall power generation of the photovoltaic panel, and avoiding the problem of difficult adjustment of installation implementation caused by fixed-angle connecting parts; through the cooperation of the locking block and the shaft rod, the shaft rod is ensured to be firmly locked, and the stability of the overall structure is enhanced. The design of the locking block and the first spring enables the fixing part to be flexibly locked, which is convenient for quick installation and can ensure firmness after installation. At the same time, disassembly also becomes simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0023] Example 1: Figure 1 、 2 The illustrated embodiment of a highly stable purlin connector for a photovoltaic support comprises a housing 1 having openings on both sides, and two fixing members 2 rotatably disposed within the openings. The fixing members 2 are rotatably connected to the housing 1 via a shaft 11. A locking block 21 is slidably disposed within the fixing member 2 for locking the shaft 11 from rotating. The locking block 21 is connected to the fixing member 2 via a first spring 22. The fixing member 2 is provided with a pin hole 23 for correspondingly engaging with the purlins.

[0024] like Figure 1 、 2 As shown, both ends of the shaft 11 are fixedly connected to the housing 1, and the shaft 11 passes through and is rotatably connected to the fixing member 2; a plurality of vertical grooves are provided on the surface of the shaft 11 in a circumferential direction, and a plurality of vertical teeth capable of correspondingly engaging with the vertical grooves are provided on the locking block 21;

[0025] like Figure 3As shown, a protrusion 24 is fixed on the surface of the fixing member 2 by a second spring. There are three protrusions in total, which are arranged in a row along the length direction of the fixing member 2. The shell 1 is provided with three groups of grooves 12 that can correspond to the protrusions 24, and each group has three, for a total of nine grooves 12.

[0026] The working principle of this embodiment is as follows: the fixing member 2 is rotated to engage the protrusion 24 with the corresponding groove 12, the purlin connection angle to be maintained is determined, the purlin is pushed forward to make the locking block 21 slide in the fixing member 2, so that the vertical teeth on the locking block 21 are engaged and locked with the vertical groove, and then the bolt is inserted into the pin hole 23 to lock and fix; when the angle needs to be adjusted, the bolt is opened, so that the locking block 21 slides back to its original position under the elastic force of the first spring 22, the lock is released, and the fixing member 2 is rotated to adjust the angle so that the protrusion 24 is replaced with the other corresponding groove 12 for engagement and pre-positioning, and then the purlin is pushed forward and the bolt is inserted into the pin hole 23 to re-lock and fix.

[0027] Example 2: The difference between this example and Example 1 is that no protrusion 24 is provided on the surface of the fixing part 2, and no groove 12 is provided on the shell 1; a first magnetic block is provided on the surface of the fixing part 2, and three groups of second magnetic blocks that can correspond to the first magnetic blocks and are provided on the shell 1 along the rotation trajectory of the fixing part 2, and each group has three, for a total of nine first magnetic blocks; the first magnetic blocks and the second magnetic blocks are both commercially available products.

[0028] Example 3: This example is different from Example 1 in that a gasket for shockproofing is provided on the contact surface between the housing 1 and the fixing member 2, and the gasket is a commercially available rubber gasket.
