Description

Technical Field

[0001] This application relates to the field of photovoltaic mounting accessories, and in particular to medium-voltage block modules. Background Technology

[0002] With the development of photovoltaic modules, the structures that are used to install photovoltaic modules have also gradually gained attention. Currently, medium-voltage blocks, brackets, and photovoltaic module frames are commonly used to support the installation of photovoltaic modules.

[0003] The utility model patent with announcement number CN220935099U proposes a medium pressure block, which includes a photovoltaic support beam. A photovoltaic panel fixing frame is set on the top of the photovoltaic support beam. A medium pressure block is set between the photovoltaic panel fixing frames. An anti-slip structure is set on the lower surface of the top of both sides of the medium pressure block. A limiting groove and a through hole are opened sequentially from top to bottom on the bottom of the medium pressure block. A first bolt passes through the inside of both the limiting groove and the through hole.

[0004] One of the aforementioned intermediate pressure blocks involves securing the locking strip on the intermediate pressure block inside the slot on the photovoltaic panel fixing frame, then inserting the lower end of the first bolt through the limiting groove and through hole, and simultaneously inserting the lower end of the first bolt through the bottom of the photovoltaic bracket crossbeam, with the top of the first bolt locked inside the limiting groove. A locking ring is then threaded onto the first bolt. Next, the second bolt is rotated, causing it to move to the left, so that the end of the second bolt engages with the annular groove, thereby locking the locking ring in place. This prevents the nut from easily loosening when the photovoltaic bracket is blown by the wind, thus preventing the intermediate pressure block from loosening and failing to secure the photovoltaic panel fixing frame. This application provides another solution to this problem. Utility Model Content

[0005] To address the aforementioned issues, this application provides a medium-pressure block assembly.

[0006] The medium-pressure block assembly provided in this application adopts the following technical solution:

[0007] A medium-pressure block assembly includes a photovoltaic support beam. Two photovoltaic fixing frames are mounted on the photovoltaic support beam. A medium-pressure block body is located between the two photovoltaic fixing frames. A fixing bolt is mounted on the medium-pressure block body. The fixing bolt passes through the medium-pressure block body and the photovoltaic support beam and is threadedly connected to a locking block. A limiting component for preventing loosening is provided on the locking block and the fixing bolt. The limiting component includes a fixing block fixedly connected to the lower surface of the locking block. A through hole is opened on the upper surface of the fixing block. The end of the fixing bolt is located within the through hole, and an annular groove is opened on its sidewall. Fixing plates are fixedly connected to the lower surface of the locking block on both sides of the fixing block. A movable plate is provided between the fixing plate and the fixing block. A limiting rod is fixedly connected to the sidewall of the movable plate near the fixing block. The end of the limiting rod away from the movable plate passes through the fixing block and is located within the annular groove. A push-pull component for pushing and pulling the limiting rod is provided on the fixing plate and the movable plate.

[0008] By adopting the above technical solution, during use, the push-pull assembly moves the movable plate, pulling the limiting rod out of the through hole. Then, the fixing bolt is rotated to connect the fixing bolt with the locking block, fixing the photovoltaic mounting frame to the photovoltaic bracket beam. At the same time, one end of the fixing bolt is located in the through hole. Then, the push-pull assembly pushes one end of the limiting rod into the annular groove, restricting the fixing bolt within the fixing block. This minimizes the problem of the nuts easily loosening when the photovoltaic bracket is blown by the wind, causing the intermediate pressure block to loosen and thus preventing the intermediate pressure block from fixing the photovoltaic panel mounting frame.

[0009] Preferably, the push-pull assembly includes a spring fixedly connected between the fixed plate and the movable plate for pushing the movable plate. A pull rod is sleeved inside the spring. One end of the pull rod is fixedly connected to the movable plate, and the other end of the pull rod passes through the fixed plate.

[0010] By adopting the above technical solution, the moving plate is moved by pulling the pull rod, which causes the spring to contract. This allows the limiting rod to be moved out of the through hole, so that the end of the fixing bolt is located in the through hole. Then, the pull rod is released to allow the spring to rebound, which pushes the moving plate and pushes the limiting rod into the annular groove.

[0011] Preferably, anti-slip toothed blocks are fixedly connected to both sides of the lower surface of the medium pressure block body to increase the friction between it and the photovoltaic fixing frame.

[0012] By adopting the above technical solution, the anti-slip toothed blocks can increase the friction between the medium-pressure block body and the photovoltaic fixing frame, thereby improving the fixing effect of the photovoltaic fixing frame.

[0013] Preferably, the end of the pull rod away from the moving plate is threaded with a limiting block to prevent the spring from rebounding.

[0014] By adopting the above technical solution, after pulling the pull rod to pull out the limiting rod, the limiting block is rotated to make the limiting block abut against the fixing plate, which can release the pull rod to prevent the spring from rebounding, and facilitate the operator to thread the fixing bolt to the locking block so that the end of the fixing bolt is located in the through hole.

[0015] Preferably, a plurality of guide rods are fixedly connected between the fixed block and the fixed plate, and the movable plate is respectively sleeved on the guide rods.

[0016] By adopting the above technical solution, the stability of the movement of the limiting rod can be improved by using the guide rod, preventing the limiting rod from shaking and making it difficult to insert into the annular groove.

[0017] Preferably, a protective tube is fixedly connected to the upper surface of the medium pressure block body, the fixing bolt is located inside the protective tube, and a waterproof sleeve is fitted on the top of the protective tube.

[0018] By adopting the above technical solution, after the fixing bolt is threadedly connected to the locking block, the waterproof sleeve is put on the protective tube to prevent rainwater from contacting the fixing bolt and corroding and rusting the fixing bolt over a long period of time, making it difficult to turn the fixing bolt when disassembling.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes the cooperative arrangement of structures such as a fixing block, annular groove, and limiting rod. During use, the push-pull assembly moves the movable plate, pulling the limiting rod out of the through hole. Then, the fixing bolt is rotated to connect with the locking block, fixing the photovoltaic fixing frame to the photovoltaic support beam. Simultaneously, one end of the fixing bolt is positioned inside the through hole. Then, the push-pull assembly pushes one end of the limiting rod into the annular groove, confining the fixing bolt within the fixing block. This minimizes the problem of the nuts easily loosening when the photovoltaic support is blown by the wind, causing the intermediate pressure block to loosen and thus preventing the intermediate pressure block from fixing the photovoltaic panel fixing frame.

[0021] 2. After pulling the lever to extend the limiting rod, rotate the limiting block to make it abut against the fixing plate. This releases the lever to prevent the spring from rebounding, allowing the operator to easily connect the fixing bolt to the locking block via thread, so that the end of the fixing bolt is located in the through hole.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] The embodiments of this application disclose a pressure block assembly.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The medium-pressure block assembly includes a photovoltaic support beam 1, two photovoltaic fixing frames 2 on the photovoltaic support beam 1, a medium-pressure block body 3 between the two photovoltaic fixing frames 2, a fixing bolt 4 on the medium-pressure block body 3, a locking block 5 threadedly connected to the medium-pressure block body 3 and the photovoltaic support beam 1, and a limiting component for preventing loosening on the locking block 5 and the fixing bolt 4. The limiting component includes a fixing block 6, a through hole 7, an annular groove 8, a fixing plate 9, a moving plate 10 and a limiting rod 11.

[0030] The fixing block 6 is fixedly connected to the lower surface of the locking block 5. The through hole 7 is opened on the upper surface of the fixing block 6. The end of the fixing bolt 4 is located in the through hole 7 and the annular groove 8 is opened on the side wall of the part of the fixing bolt 4 located in the through hole 7. Two fixing plates 9 are provided and fixedly connected to the lower surface of the locking block 5 on both sides of the fixing block 6. Two moving plates 10 are provided and located between the fixing plates 9 and the fixing block 6. Two limiting rods 11 are provided and fixedly connected to the side wall of the moving plate 10 near the fixing block 6. The end of the limiting rod 11 away from the moving plate 10 passes through the fixing block 6 and is located in the annular groove 8. The fixing plate 9 and the moving plate 10 are provided with push-pull components for pushing and pulling the limiting rods 11.

[0031] Reference Figure 1 and Figure 3The push-pull assembly includes a spring 12 fixedly connected between the fixed plate 9 and the movable plate 10 for pushing the movable plate 10. A pull rod 13 is sleeved inside the spring 12. One end of the pull rod 13 is fixedly connected to the movable plate 10, and the other end of the pull rod 13 passes through the fixed plate 9. By pulling the pull rod 13, the movable plate 10 is moved, causing the spring 12 to contract. This allows the limiting rod 11 to be moved out of the through hole 7, so that the end of the fixing bolt 4 is located in the through hole 7. Then, the pull rod 13 is released, causing the spring 12 to rebound, which pushes the movable plate 10 and pushes the limiting rod 11 into the annular groove 8.

[0032] Reference Figure 4 The lower surface of the medium pressure block body 3 is fixedly connected with anti-slip toothed blocks 14 on both sides to increase the friction between the medium pressure block body 3 and the photovoltaic fixing frame 2. The anti-slip toothed blocks 14 can increase the friction between the medium pressure block body 3 and the photovoltaic fixing frame 2, thereby improving the fixing effect of the photovoltaic fixing frame 2.

[0033] Reference Figure 3 The end of the pull rod 13 away from the moving plate 10 is threaded with a limiting block 15 to prevent the spring 12 from rebounding. After the pull rod 13 is pulled out to pull out the limiting rod 11, the limiting block 15 is rotated to make the limiting block 15 abut against the fixed plate 9, which can release the pull rod 13 to prevent the spring 12 from rebounding. This makes it convenient for the operator to thread the fixing bolt 4 to the locking block 5 so that the end of the fixing bolt 4 is located in the through hole 7.

[0034] Reference Figure 3 Multiple guide rods 16 are fixedly connected between the fixed block 6 and the fixed plate 9. The movable plate 10 is respectively sleeved on the guide rods 16. The guide rods 16 can improve the stability of the movement of the limiting rod 11 and prevent the limiting rod 11 from shaking and being difficult to insert into the annular groove 8.

[0035] Reference Figure 1 A protective tube 17 is fixedly connected to the upper surface of the medium pressure block body 3. The fixing bolt 4 is located inside the protective tube 17. A waterproof sleeve 18 is fitted on the top of the protective tube 17. After the fixing bolt 4 is threadedly connected to the locking block 5, the waterproof sleeve 18 is fitted on the protective tube 17 to prevent rainwater from contacting the fixing bolt 4. Over time, the fixing bolt 4 will corrode and rust, making it difficult to rotate the fixing bolt 4 during disassembly.

[0036] The implementation principle of the pressure block assembly in this embodiment is as follows: In use, the user first pulls the pull rod 13 to move the moving plate 10, causing the spring 12 to contract and the limiting rod 11 to move out of the through hole 7. Then, the user rotates the limiting block 15 to make the limiting block 15 abut against the fixing plate 9, which can release the pull rod 13 to prevent the spring 12 from rebounding. Then, the user rotates the fixing bolt 4 to make the fixing bolt 4 threadedly connected to the locking block 5, fixing the photovoltaic fixing frame 2 between the photovoltaic bracket crossbeam 1 and the middle pressure block body 3. At the same time, one end of the fixing bolt 4 is located in the through hole 7. Then, the user rotates the limiting block 15 to make the spring 12 rebound, which can push the moving plate 10 and push the limiting rod 11 into the annular groove 8, restricting the fixing bolt 4 in the fixing block 6. This avoids the problem that when the photovoltaic bracket is blown by the wind, the nuts are easy to loosen, causing the middle pressure block to loosen and making it impossible for the middle pressure block to fix the photovoltaic panel fixing frame.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
