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

[0002] Solar photovoltaic (PV) brackets are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel. Due to the variety of solar PV bracket types, the pressure blocks used also vary. Currently, there are mainly two types: edge pressure blocks and center pressure blocks. The center pressure blocks are used to secure the main components, ensuring proper connection between them, and also connect with the guide rails, thus forming a stable whole within the solar PV bracket.

[0003] A search revealed a Chinese patent with authorization announcement number CN217037093U, which discloses a pressure block in a photovoltaic bracket accessory, including an installation block. The lower end of the installation block is respectively equipped with a first locking rod and a second locking rod, and the end of the second locking rod near the first locking rod has a mating hole.

[0004] The photovoltaic bracket accessory in the aforementioned patent has the following shortcomings: Although the device can improve the stability of the photovoltaic panel by limiting its position and prevent the photovoltaic panel and the photovoltaic block from shaking, and the device is connected to the mounting block by fastening bolts, the fastening bolts do not have an anti-loosening structure. Therefore, when the photovoltaic bracket is blown by the wind or used for a long time, it is easy to loosen, which will cause the photovoltaic photovoltaic bracket to loosen. This affects the stability and safety of the photovoltaic bracket fixing the photovoltaic panel frame. Utility Model Content

[0022] 1. This application employs a positioning plate and other components. By loosening the positioning plate and through the automatic reset action of the telescopic rod and telescopic spring, the positioning plate comes into contact with the top of the fastening bolt, initially limiting the position of the fastening bolt. Then, the reinforcing post is inserted into the first and second round holes, and the nut is rotated to fix the position of the positioning plate. This improves the positioning and installation of the fastening bolt, thus preventing the photovoltaic bracket from becoming loose due to wind or prolonged use. Therefore, it further enhances the stability and safety of the photovoltaic bracket in fixing the photovoltaic panel frame.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] The embodiments of this application disclose a pressure block.

[0031] Reference Figure 1-3 The intermediate pressure block includes a mounting block 1, an intermediate pressure block 2 disposed on the mounting block 1, and the mounting block 1 is provided with a mounting groove 18 for connecting with the crossbeam, and a fixing mechanism disposed on the intermediate pressure block 2.

[0032] The fixing mechanism includes threaded holes 6 on the mounting block 1 and the intermediate pressure block 2, fastening bolts 5 screwed into the threaded holes 6, a positioning plate 8 on the top of the fastening bolts 5, a first round hole 12 and a second round hole 14 on the top of the positioning plate 8 and the fastening bolts 5 respectively, and the same reinforcing column 15 is slidably installed in both the first round hole 12 and the second round hole 14, a thread 16 on one side of the outer surface of the reinforcing column 15, and a nut 17 screwed into the thread 16.

[0033] In use, by inserting the reinforcing post 15 into the first round hole 12 and the second round hole 14, and rotating the nut 17, the position of the positioning plate 8 can be limited and fixed, thereby improving the positioning and installation of the fastening bolt 5. This prevents the photovoltaic bracket from being easily loosened by wind or prolonged use, thus further improving the stability and safety of the photovoltaic bracket's fixation of the photovoltaic panel frame.

[0034] Reference Figure 2-4 The fixing mechanism also includes two elongated slots 7 symmetrically opened on both sides of the central pressure block 2, two connecting plates 9 fixedly installed on both sides of the positioning plate 8, and both connecting plates 9 are slidably installed in the corresponding elongated slots 7, two telescopic rods 10 fixedly installed on the inner top walls of the two elongated slots 7, and the telescopic ends of the two telescopic rods 10 are fixedly connected to the corresponding connecting plates 9, two telescopic springs 11 sleeved on the two telescopic rods 10, and the telescopic length of the telescopic rods 10 is greater than the overall length of the fastening bolt 5. Since the telescopic length of the telescopic rods 10 is greater than the overall length of the fastening bolt 5, there will be no movement interference. Two pull rods 13 symmetrically fixedly installed on the top of the positioning plate 8, anti-slip pads set on the bottom of the positioning plate 8 and the nut 17, the anti-slip pads can increase the friction. The locking teeth 3 set on the central pressure block 2 and the wear-resistant pads 4 set on the top of the central pressure block 2.

[0035] In use, by loosening the positioning plate 8, and through the automatic reset action of the telescopic rod 10 and the telescopic spring 11, the positioning plate 8 will come into contact with the top of the fastening bolt 5, and the fastening bolt 5 will be initially limited.

[0036] The implementation principle of the pressure block in this embodiment is as follows: When in use, the mounting block 1 is first connected to the crossbeam, then the photovoltaic panel can be placed, and the middle pressure block 2 is placed in the gap between two adjacent photovoltaic panels. The middle pressure block 2 is pressed against the edge of the photovoltaic panel by the locking teeth 3. Then the positioning plate 8 is pulled upward, so that the fastening bolt 5 can pass through the middle pressure block 2 and be tightened onto the mounting block 1, which improves the stability of the connection between the middle pressure block 2 and the mounting block 1, so that the photovoltaic panel fixing frame can be stably fixed on the top of the photovoltaic bracket crossbeam.

[0037] By loosening the positioning plate 8 and through the automatic reset action of the telescopic rod 10 and the telescopic spring 11, the positioning plate 8 will come into contact with the top of the fastening bolt 5, and the fastening bolt 5 will be initially limited. At this time, the reinforcing column 15 is inserted into the first round hole 12 and the second round hole 14, and the nut 17 is rotated, so that the position of the positioning plate 8 can be limited and fixed, thereby improving the positioning and installation of the fastening bolt 5. Therefore, it can prevent the photovoltaic bracket from being blown by the wind or from being loosened by long-term use, thus further improving the stability and safety of the photovoltaic bracket 2 in fixing the photovoltaic panel frame.

[0038] 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.
