Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and particularly relates to a connecting piece. Background Art

[0002] The connecting piece is an important component during the on-site installation of photovoltaic panels. By using the gap between two connecting pieces to clamp the frame of the photovoltaic panel module, and at the same time connecting and fixing one of the connecting pieces to the installation platform where it is located, the fixation of the photovoltaic panel frame is realized. The four corners of the photovoltaic panel frame are all fixed to complete the effective installation of the photovoltaic panel frame.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN220693025U: A component for connecting photovoltaic modules, which discloses including an installation plate. The installation plate is connected to a load-bearing cable. The installation plate at least includes an A surface. Multiple parallel bars are arranged on the A surface. The bars divide the installation plate into at least a first side wing and a second side wing. Long holes are provided on both the first side wing and the second side wing. The long holes are parallel to the bars. The long holes are used to connect the photovoltaic modules, and the bars are used to prevent the photovoltaic modules from moving. A technical solution that can stably connect the installation plate and the photovoltaic module by using a bolt pair to pass through the long holes can be adopted. When the vertical distance between the load-bearing cables changes, the bolts can slide in the long holes to adjust the relative position between the photovoltaic module and the flexible load-bearing cable to adapt to the change of the vertical distance between the load-bearing cables. Multiple parallel bars are arranged on the A surface of this connecting component to form a mechanical stop for the side wall of the photovoltaic module, limit the displacement of the photovoltaic module, and reduce the probability of the photovoltaic module being damaged.

[0004] The above-mentioned utility model patent discloses a connecting piece that can be applied to a flexible photovoltaic support, but there are technical problems of complex structure and poor installation stability. Therefore, there is an urgent need in the field for a connecting piece to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connecting piece to solve the above deficiencies in the prior art.

After a bolt penetrates through the first mounting hole, it is fixedly connected to an external mounting base, for example, connected to a protrusion on the top of an external color steel tile. Then, the bolt simultaneously penetrates through the second mounting hole and other external sheet-like connecting pieces. The external sheet-like connecting pieces are placed parallel to the side piece, and a clamping space can be formed between the external sheet-like connecting pieces and the side piece. The corner of the photovoltaic panel frame is inserted into the clamping space, and then the bolt is tightened, so that the photovoltaic panel frame can be clamped, and it can be applied to the fixed installation of the photovoltaic panel assembly at the installation site.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0024] As Figure 1 - Figure 2 shown, a connecting piece provided by an embodiment of the present utility model includes two side pieces 101 and a convex part 102 connected between the two side pieces 101. The convex part 102 protrudes upward, and a groove 103 is formed below the convex part 102. Two first mounting holes 104 are vertically penetrated through the top surface of the convex part 102, and one second mounting hole 105 is vertically penetrated through the side piece 101. After a bolt penetrates through the first mounting hole 104, it is connected to the top protrusion of the external color steel tile. Then, the bolt penetrates through the second mounting hole 105 and other external sheet-like connecting pieces at the same time. The external sheet-like connecting pieces are placed parallel to the side piece 101, and a clamping space can be formed between the external sheet-like connecting pieces and the side piece 101. The corners of the photovoltaic panel frame are inserted into the clamping space, and then the bolt is tightened, so that the photovoltaic panel frame can be clamped, and it can be applied to the fixed installation of the photovoltaic panel assembly at the installation site.

[0025] The side piece 101 and the convex part 102 are integrally bent and formed.

[0027] On the lower surface of the side piece 101, a ratchet 106 is provided in the area near the second mounting hole 105. By using a bolt with a ratchet as well, which cooperates with the ratchet 106, the bolt after locking will not become loose.

[0028] The groove 103 is rectangular, making the top surface of the protrusion 102 flat, which is beneficial for cooperation with the bolt and reduces the installation difficulty.

[0029] The first mounting hole 104 is an oblong hole, which can improve the adaptability to installation errors.

[0030] The width of the groove 103 is 14 mm. When installing the bolt at the position of the first mounting hole 104, an M8 bolt is used. The M8 bolt head is located below. After installation, the M8 bolt head is stuck in the groove 103 and cannot rotate. An external sheet-like connecting piece is provided above the side piece 101. After the top of the M8 bolt passes through the mounting hole of the external sheet-like connecting piece, a nut is tightened from the top of the M8 bolt. The installation is convenient. When tightening the M8 bolt, there is no need to hold one end of the M8 bolt head to improve the installation efficiency.
