Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, specifically to a connector and mounting bracket. Background Technology

[0002] A solar photovoltaic (PV) bracket is a support structure designed for placing, installing, and fixing solar panels in a solar PV power generation system.

[0003] In the prior art, multiple M-purlins are usually installed on the inclined beam of the photovoltaic support. The M-purlins are connected to the square tube of the inclined beam by L-shaped connectors. The side of the M-purlin and one side of the L-shaped connector are provided with mounting holes for bolts to pass through. The M-purlins and the L-shaped connectors are fixed by two bolts. The other side of the L-shaped connectors is connected to the square tube of the support beam by a clamp.

[0004] However, during the on-site installation, there were instances where the mounting holes of the M-purlins and L-shaped connectors could not be aligned, resulting in a reduction in the number of purlins to be installed. Furthermore, feedback from the site indicated that a large number of bolts were required, leading to a longer installation time and greater construction difficulty. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the difficulty of installing purlins and connectors in the prior art, thereby providing a connector and mounting bracket.

[0006] To solve the above-mentioned technical problems, this utility model provides a connector, including: a connecting part, a hook part, and a fixing part. The hook part is disposed at one end of the connecting part and is used to hook onto a purlin. The fixing part is disposed at the end of the connecting part away from the hook part and is used to connect to a support beam.

[0007] In use, the connecting part integrates the hook part and the fixing part into a Z-shaped structure. The hook part is hung on one side of the upper end of the purlin, and the fixing part is fixedly connected to the support beam, thereby limiting and fixing the purlin. This eliminates the need for bolts, avoids the problem of misaligned holes, ensures the number of connectors that can be installed, and improves installation speed. Furthermore, under wind suction, the hook part can exert downward pressure on the purlin, improving stability. The connector provided by this utility model solves the problem of high installation difficulty of purlins and connectors in the prior art.

[0008] Optionally, the hook portion includes: a pressure plate and a bending plate; the pressure plate is disposed at one end of the connecting portion, and the pressure plate is used to press against the upper end face of the purlin; the bending plate is disposed at the end of the pressure plate away from the connecting portion, and the bending plate is used to press against the side of the purlin. With the above arrangement, the pressure plate can press down on the upper end of the purlin, and the bending plate can limit the purlin's position, preventing the purlin from detaching from the hook portion.

[0009] Optionally, the bending plate is inclined away from the connecting portion. With this arrangement, the inclined bending plate can fit snugly against the side wall of the M-shaped purlin, ensuring close contact between the hook portion and the upper end of the M-shaped purlin, thus reducing swaying.

[0010] Optionally, the connecting part is provided with at least one fixing hole, which is used for mating with the mounting hole of the purlin through a fastener. With the above arrangement, the fastener passes through the fixing hole and the mounting hole on the purlin to connect the connecting part with the purlin, thereby improving the connection strength between the connecting part and the purlin.

[0011] Optionally, the fixing hole is configured as a strip-shaped hole, extending in a direction perpendicular to the fixing part. With this configuration, the fixing hole is a strip-shaped hole perpendicular to the fixing part, allowing adjustment of the connector's position along this perpendicular path and preventing misalignment between the fixing hole and the purlin's mounting hole.

[0012] Optionally, a raised rib is provided at the connection between the connecting part and the fixing part. This rib strengthens the connection between the connecting part and the fixing part, preventing changes in the angle between them during use.

[0013] Optionally, the fixing part is provided with positioning holes for installing clamps that connect to the support beam. With this configuration, the positioning holes on the fixing part limit and fix the clamps, thereby securing the fixing part to the support beam.

[0014] Optionally, the width of the connecting part is smaller than the width of the fixing part. By adopting the above configuration, while meeting the width requirements for connecting the fixing part to the support beam, reducing the width of the connecting part and the hook part can save materials and reduce costs.

[0015] This utility model provides an installation bracket, including a bracket beam, purlins, and a connector as described in any of the above embodiments. Multiple purlins are provided on the bracket beam. The hook portion of the connector is hung on the upper end of the purlin, and the fixing portion of the connector is connected to the bracket beam. Due to the use of the above-described connector, it possesses any of the aforementioned advantages.

[0016] Optionally, a mounting hole is provided on the side of the purlin that contacts the connecting portion of the connector. The mounting hole is a strip-shaped hole perpendicular to the fixing hole of the connector and extends in a direction parallel to the fixing portion. This arrangement allows for adjustment of the connector's position along both the extending directions of the fixing hole and the mounting hole, preventing misalignment between them.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] This embodiment provides a connector structure that can reduce installation difficulty, used for connecting the purlin 9 and the support beam in a photovoltaic bracket.

[0030] like Figure 1 As shown, this embodiment provides a specific implementation of a connector, including: a connecting part 1, a hook part 2, and a fixing part 3. The hook part 2 is disposed at one end of the connecting part 1 and is used to hook onto the purlin 9. The fixing part 3 is disposed at the end of the connecting part 1 away from the hook part 2 and is used to connect to the support beam.

[0031] In use, the connecting part 1 connects the hook part 2 and the fixing part 3 into a single unit, forming a Z-shaped structure. The hook part 2 is hung on one side of the upper end of the purlin 9, and the fixing part 3 is fixedly connected to the support beam, thereby limiting and fixing the purlin 9. This eliminates the need for bolts, avoiding the problem of misaligned holes, ensuring the number of connectors that can be installed, improving installation speed, and, under wind suction, the hook part 2 can exert downward pressure on the purlin 9, improving stability. The connector provided in this embodiment solves the problem of high installation difficulty for purlins 9 and connectors in the prior art.

[0032] like Figure 1 , Figure 2 As shown, in the connector provided in this embodiment, the hook portion 2 includes: a pressing plate 4 and a bending plate 5; the pressing plate 4 is disposed at one end of the connecting portion 1, and the pressing plate 4 is used to press against the upper end surface of the purlin 9; the bending plate 5 is disposed at the end of the pressing plate 4 away from the connecting portion 1, and the bending plate 5 is used to press against the side surface of the purlin 9. The pressing plate 4 can press down on the upper end of the purlin 9, and the bending plate 5 can limit the purlin 9, preventing the purlin 9 from detaching from the hook portion 2. In addition, as an alternative embodiment, the hook portion 2 can also be provided with multiple hooks along the length direction of the connecting portion 1.

[0033] like Figure 1 , Figure 2 As shown, in the connector provided in this embodiment, the bending plate 5 is inclined away from the connecting portion 1. The inclined bending plate 5 can fit against the side wall of the M-shaped purlin 9, so that the hook portion 2 is in close contact with the upper end of the M-shaped purlin 9, reducing swaying. Alternatively, as an alternative embodiment, the bending plate 5 can also be arranged parallel to the connecting portion 1.

[0034] like Figure 1 , Figure 3 As shown, in the connector provided in this embodiment, the connecting part 1 is provided with at least one fixing hole 6, which is used to mate with the mounting hole 10 of the purlin 9 via a fastener. The fastener passes through the fixing hole 6 and the mounting hole 10 on the purlin 9, so that the connecting part 1 is connected to the purlin 9, thereby improving the connection strength between the connector and the purlin 9. Alternatively, as an alternative embodiment, the fixing hole 6 can be omitted, and the connector can be fixed to the purlin 9 only by the hook part 2.

[0035] like Figure 1 , Figure 3 As shown, in the connector provided in this embodiment, the fixing hole 6 is a strip-shaped hole that extends along a direction perpendicular to the fixing part 3. The fixing hole 6 is a strip-shaped hole perpendicular to the fixing part 3, allowing adjustment of the connector's position along this perpendicular path and preventing misalignment between the fixing hole 6 and the mounting hole 10 of the purlin 9. Alternatively, as an alternative implementation, the fixing hole 6 can also be a circular hole according to design requirements.

[0036] like Figure 1 As shown, in the connector provided in this embodiment, a raised reinforcing rib 7 is provided at the connection between the connecting part 1 and the fixing part 3. The reinforcing rib 7 can strengthen the connection between the connecting part 1 and the fixing part 3 and prevent the angle between the fixing part 3 and the connecting part 1 from changing during use. In addition, as an alternative embodiment, the reinforcing rib 7 can be omitted, and a rib plate can be provided between the connecting part 1 and the fixing part 3.

[0037] like Figure 1 , Figure 4 As shown, in the connector provided in this embodiment, the fixing part 3 is provided with a positioning hole 8, which is used to install the clamp connecting the support beam. The positioning hole 8 on the fixing part 3 limits and fixes the clamp, and the fixing part 3 is fixedly connected to the support beam by the clamp. In addition, as an alternative embodiment, the positioning hole 8 can be omitted, and the fixing part 3 can be fixed by bolts, welding or bonding or other methods.

[0038] like Figure 1 , Figure 4 As shown, in the connector provided in this embodiment, the width of the connecting part 1 is smaller than the width of the fixing part 3. While meeting the width requirement for the fixing part 3 to connect the clamp to the support beam, reducing the width of the connecting part 1 and the hook part 2 can save materials and reduce costs. Specifically, the connection between the fixing part 3 and the connecting part 1 is configured as a reduced-width structure. Alternatively, as an alternative implementation, the widths of the connecting part 1 and the fixing part 3 can be the same.

[0039] How to use:

[0040] like Figure 1 As shown, in use, the connector provided in this embodiment connects the hook part 2 and the fixing part 3 into a single unit to form a Z-shaped structure. The hook part 2 is hung on one side of the upper end of the purlin 9, and the fixing part 3 is fixedly connected to the support beam, thereby limiting and fixing the purlin 9. When further fixing is required, the fixing hole 6 is connected to the mounting hole 10 of the purlin 9 by fasteners.

[0041] In addition, this embodiment also provides an installation bracket, including a bracket beam, purlins 9, and the connector described in the above embodiments. Multiple purlins 9 are provided on the bracket beam. The hook portion 2 of the connector is hung on the upper end of the purlin 9, and the fixing portion 3 of the connector is connected to the bracket beam. By using the connector described in the above embodiments, rapid installation of the purlins 9 is achieved.

[0042] It should be noted that the purlin 9 can be an M-shaped purlin 9, or a square or other structured purlin 9, as needed.

[0043] like Figure 1 , Figure 5 As shown, in the mounting bracket provided in this embodiment, a mounting hole 10 is provided on the side of the purlin 9 that contacts the connecting portion 1 of the connector. The mounting hole 10 is a strip-shaped hole perpendicular to the fixing hole 6 of the connector, and extends in a direction parallel to the fixing portion 3. The position of the connector can be adjusted along both the extending directions of the fixing hole 6 and the mounting hole 10, preventing situations where the fixing hole 6 and the mounting hole 10 cannot align. Alternatively, as an alternative embodiment, the mounting hole 10 can also be a circular hole.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
