Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module frame support technology, and in particular to a photovoltaic module frame support that is easy to adjust in height. Background Technology
[0002] An adjustable photovoltaic module frame bracket is a structural component used to install and support photovoltaic modules, and whose height can be flexibly changed according to actual needs. It has the following structure: 1. Three support plates: The support structure consists of three support plates: a horizontal plate, an inclined plate, and a vertical plate. The horizontal plate serves as the basic support and is in contact with the installation surface (such as the ground or photovoltaic base). The inclined plate is used to support the photovoltaic modules and can be adjusted to accommodate height changes by changing the angle. The vertical plate connects the horizontal plate and the inclined plate to form a stable triangle and ensure the overall structural strength of the support. 2. Adjustment holes: These provide support for height adjustment on the horizontal, inclined, and vertical plates, and are also used to pass through bolts and nuts for fixing. 3. Bolts and nuts: As connecting and fastening components, after being inserted into the adjustment holes, they are tightened with nuts to lock the relative position between the bracket plates and fix the adjusted height and angle.
[0003] In actual use, the photovoltaic module frame bracket is located outdoors. The outdoor environment is complex, and the bolts and nuts are easily affected by external forces such as wind and vibration, which causes the preload of the nuts and bolts to continuously decrease. At this time, the bolts are prone to displacement or loosening in the adjustment hole. The clamping force of the bolts and nuts on the bracket plate is reduced, which causes the bracket to shake and thus reduces the stability of the photovoltaic module installation on the bracket. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a photovoltaic module frame bracket that is easy to adjust in height. It solves the technical problem that bolts and nuts are easily affected by external forces such as wind and vibration, causing the preload of the nuts and bolts to continuously decrease. In this case, the bolts are prone to displacement or loosening in the adjustment hole, and the clamping force of the bolts and nuts on the bracket plate is reduced, which causes the bracket to shake and thus reduces the stability of the photovoltaic module installation on the bracket.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A photovoltaic module frame bracket with adjustable height includes a bracket plate, adjustment holes, and bolts. Several adjustment holes are located on the outside of the bracket plate, and the bolts are slidably connected inside the adjustment holes. A limiting mechanism for restricting bolt movement is provided on the outside of the bracket plate. The limiting mechanism includes a mounting shaft, a mounting hole, a limiting rod, and a limiting hole. The end of the mounting shaft is rotatably connected inside the adjustment hole, and the mounting hole is located outside the mounting shaft. One end of the limiting rod is slidably connected inside the mounting hole, and the limiting hole is located outside the bolt. The other end of the limiting rod is engaged inside the limiting hole to restrict bolt movement. A push plate is fixedly installed on the outside of the limiting rod.
[0006] Preferably, the mounting hole has a spring fixedly connected inside to support the limiting rod.
[0007] Preferably, a movable hole is provided on the side of the mounting shaft corresponding to the mounting hole, and a limiting shaft is slidably connected inside the movable hole. The limiting shaft is set outside the limiting rod, and a threaded hole is provided on the side of the limiting rod corresponding to the limiting shaft. A screw is threadedly connected inside the threaded hole, and the screw is fixedly installed outside the limiting shaft.
[0008] Preferably, the side of the limiting shaft away from the screw has a groove.
[0009] Preferably, the screw is fitted with a washer on its external movable sleeve.
[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. After adjusting the height of the photovoltaic module frame bracket, insert the mounting shaft into the adjustment hole near the bolt. At this time, insert one end of the limiting rod into the inside of the mounting hole, press the limiting rod so that it partially enters the mounting hole, compressing the spring inside the mounting hole. Rotate the mounting shaft, and the mounting shaft will drive the limiting rod to move synchronously until the limiting rod moves to the corresponding position of the limiting hole opened on the outside of the bolt. Push the limiting rod so that its other end is locked into the limiting hole. At this time, the bolt is restricted by the limiting rod and cannot move in the adjustment hole, thus preventing the bolt from shifting in the adjustment hole, ensuring the clamping force of the bolt and nut on the bracket plate, preventing the bracket from shaking, and ensuring the stability of the photovoltaic module installation on the bracket. 2. The threaded hole and the screw on the limit shaft are connected by a thread, which enables the limit rod and the limit shaft to be detachable. When the limit mechanism is not needed, the connection between the limit rod and the limit shaft is released, and then the limit rod is pulled to release the connection between the limit rod and the mounting hole. At this time, the mounting shaft can be pulled to release the connection between the mounting shaft and the adjustment hole. At this time, the limit mechanism is disassembled, which makes it easy to disassemble and assemble the limit mechanism according to the working conditions and improves the flexibility of the use of the limit mechanism.

[0014] This application provides a photovoltaic module frame bracket that is easy to adjust in height. It effectively solves the technical problem that the preload of bolts and nuts is constantly reduced due to external forces such as wind and vibration. At this time, the bolts are prone to displacement or loosening in the adjustment hole. The clamping force of the bolts and nuts on the bracket plate is reduced, which causes the bracket to shake and thus reduces the stability of the photovoltaic module installation on the bracket.
[0015] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that bolts and nuts are easily affected by external forces such as wind and vibration, causing the preload of the nuts and bolts to continuously decrease. This leads to displacement or loosening of the bolts within the adjustment hole, reducing the clamping force of the bolts and nuts on the bracket plate, causing bracket swaying, and consequently decreasing the stability of the photovoltaic module installation on the bracket. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides a photovoltaic module frame bracket that is easy to adjust in height, including a bracket plate 1, adjustment holes 2, and bolts 3. There are several adjustment holes 2, which are opened on the outside of the bracket plate 1. The bolts 3 are slidably connected to the inside of the adjustment holes 2. A limiting mechanism for restricting the movement of the bolts 3 is provided on the outside of the bracket plate 1. The limiting mechanism includes a mounting shaft 4, a mounting hole 5, a limiting rod 6, and a limiting hole 7. The end of the mounting shaft 4 is rotatably connected to the inside of the adjustment hole 2. The mounting hole 5 is opened on the outside of the mounting shaft 4. One end of the limiting rod 6 is slidably connected to the inside of the mounting hole 5. The limiting hole 7 is opened on the outside of the bolts 3. The other end of the limiting rod 6 is engaged with the inside of the limiting hole 7 and used to restrict the movement of the bolts 3. A push plate 15 is fixedly installed on the outside of the limiting rod 6.
[0016] Limiting mechanism: The mounting shaft 4 is inserted into the bolt 3 near the adjusting hole 2, providing a carrier for the installation and movement of components such as the limiting rod 6 and the limiting shaft 10. By rotating itself, it drives the limiting rod 6 to move, realizing the alignment of the limiting rod 6 with the limiting hole 7 of the bolt 3. The mounting hole 5 provides sliding space and installation position for the limiting rod 6. The limiting hole 7 cooperates with the limiting rod 6, and the bolt 3's degree of freedom of movement is restricted by the locking of the limiting rod 6.
[0017] The mounting hole 5 is internally fixedly connected to a spring 8 for supporting the limiting rod 6. When the limiting rod 6 is pressed, it is compressed and stores energy. When released, the spring 8 pushes the limiting rod 6 out, so that the limiting rod 6 is locked into the limiting hole 7.
[0018] A movable hole 9 is provided on one side of the mounting shaft 4 corresponding to the mounting hole 5. A limiting shaft 10 is slidably connected inside the movable hole 9. The limiting shaft 10 is located outside the limiting rod 6 and is used to limit the movement range of the limiting rod 6.
[0019] The limiting rod 6 has a threaded hole 11 on one side corresponding to the limiting shaft 10. A screw 12 is threadedly connected inside the threaded hole 11. The screw 12 is fixedly installed on the outside of the limiting shaft 10. The threaded hole 11 and the screw 12 on the limiting shaft 10 are threadedly connected, so that the limiting rod 6 and the limiting shaft 10 can be disassembled, thereby facilitating the disassembly of the limiting mechanism.
[0020] The limiting shaft 10 has a groove 13 on the side away from the screw 12, which makes it easy to use a tool to insert into the groove 13 to rotate the limiting shaft 10.
[0021] A washer 14 is fitted to the external movable sleeve of the screw 12 to reduce the probability of the screw 12 becoming loose.
[0022] Working principle: First, after adjusting the height of the photovoltaic module frame bracket, insert the mounting shaft 4 into the adjustment hole 2 near the bolt 3. Then, insert one end of the limiting rod 6 into the mounting hole 5. Then, thread the screw 12 into the threaded hole 11. At this time, the limiting shaft 10 enters the moving hole 9 at one end. Press the limiting rod 6 so that it partially enters the mounting hole 5, compressing the spring 8 in the mounting hole 5. Rotate the mounting shaft 4. During the rotation of the mounting shaft 4, the limiting rod 6 moves synchronously until the limiting rod 6 moves to the corresponding position of the limiting hole 7 opened outside the bolt 3. Release the limiting rod 6. Under the elastic force of the spring 8 restoring its deformation, the limiting rod 6 pops out, and the other end is stuck into the limiting hole 7. At this time, the bolt 3 is restricted by the limiting rod 6 and cannot move in the adjustment hole 2. The relative position of the bracket plate 1 is fixed, realizing the locking of the adjusted height and ensuring that the photovoltaic module frame bracket stably supports the photovoltaic module at the set height. The second step involves adjusting the height of the bracket. The bracket consists of three bracket plates 1: a horizontal plate, an inclined plate, and a vertical plate. The horizontal plate is in contact with the ground. The angle formed by the inclined plate and the horizontal plate can adjust the height of the bracket. The two ends of the vertical plate are connected to the horizontal plate and the inclined plate, respectively, to fix the height of the bracket. It is necessary to disconnect the connection between the bolts 3 and nuts on the two bracket plates 1. At this time, push the push plate 15 to move the limit rod 6. At this time, the connection between the limit rod 6 and the limit hole 7 is released. Then, rotate the mounting shaft 4 to make the mounting shaft 4 drive the limit rod 6 to rotate away from the bolts 3. At this time, the nut can be rotated to move the nut away from the bracket plate 1. The bracket plate 1 can then be rotated to adjust the height of the bracket.
[0023] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
