The fixture body is designed to mimic the shape of the photovoltaic module frame profile and is divided into upper and lower profile placement parts. The two sides of each profile placement part are a profile B-side limiting plate and a lamination limiting plate, respectively. A limiting partition is provided in the middle of the lamination limiting plate to separate the profile placement parts. The upper part is the profile A-side placement part, and the lower part is the profile lamination support placement part. The photovoltaic module frame profile can slide into the fixture body from the side. The fixture body moves to the middle of the profile, where a punched hole is located on the C-side. The clamping part is located in the middle of the upper part of the fixture body. The lifting mechanism includes clamping bolts, a set of nuts, and a set of washers. During installation, the clamping bolts pass through the punched hole in the middle of the C-side of the photovoltaic module frame profile.

[0005] Furthermore, the aforementioned photovoltaic module frame profile load test fixture is manufactured as a single piece, with the fixture body and clamping part integrally formed and processed using a quenching process and wire cutting to improve hardness and durability.

[0006] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the B-side limiting plate is a straight surface, and the length of the B-side limiting plate is longer than that of the laminated limiting plate, so as to provide a better limiting effect.

[0007] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the lower end of the lamination limiting plate bends inward toward the lamination support placement part, providing a limit to the profile during load tension.

[0008] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the clamping parts have a straight-face design on both sides for easy clamping.

[0009] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the clamping bolt is divided into a threaded part and a clamping part. The threaded part is equipped with a nut and a washer for fastening the installation profile.

[0010] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the clamping part has a planar structure milled on both sides for easy clamping.

[0011] Furthermore, in the aforementioned photovoltaic module frame profile load test fixture, the outer contour corners of the fixture body and clamping part are designed with rounded corners to improve safety and aesthetics, and to prevent scratching the profile.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: The photovoltaic module frame profile load test fixture described in this utility model uses quenching process and wire cutting processing, resulting in high hardness, good wear resistance, and long service life; the internal contour design of the fixture ensures good fit with the solar photovoltaic module profile, and multiple points of constraint on the profile at the contour point during the load test ensure that the profile is firmly fixed in the fixture, improving the test accuracy; the profile can be directly slid into the fixture from the side, making the operation simple and quick, reducing installation time; the clamping bolts are directly tightened with nuts on both sides of the C-side of the profile, making installation convenient and the fixation reliable; the fixture and bolt design facilitates clamping and operation; the fixture design is compatible with closed and open section profiles, has strong versatility, and reduces the fixture development cost.

[0015] Example

[0016] like Figure 1-4 The fixture shown includes a photovoltaic module frame profile load test fixture, comprising: fixture body 1, clamping part 2, and lifting mechanism 3. The fixture body 1 is internally designed to mimic the shape of the photovoltaic module frame profile and is divided into upper and lower profile placement parts. The profile placement parts have a profile B-side limiting plate 11 and a lamination limiting plate 12 on either side. A limiting partition 13 is provided in the middle of the lamination limiting plate 12 to separate the profile placement parts. The upper part is the profile A-side placement part 14, and the lower part is the profile lamination support placement part 1. 5. The photovoltaic module frame profile can slide in from the side of the fixture body 1. The fixture body 1 moves to the middle of the profile, and the C-side of the profile has a punched hole design. The clamping part 2 is located in the middle of the upper part of the fixture body 1. The lifting mechanism 3 includes clamping bolts 31, a set of nuts 32, and a set of washers 33. During installation, the clamping bolts 31 pass through the punched hole in the middle of the C-side of the photovoltaic module frame profile. Washers 33 and nuts 32 are arranged sequentially from the inside to the outside on both sides of the C-side. Tightening the nuts 32 on both sides locks and fixes the profile. During installation, the clamping bolts 31 pass through the punched hole in the middle of the C-side of the profile, and then washers 33 and nuts 32 are sequentially placed on both sides of the C-side. Tightening the nuts 32 will fasten the profile to the fixture body 1. The washers 33 can distribute pressure and prevent damage to the surface of the profile.

[0017] In this embodiment, the tooling body 1 and the clamping part 2 are integrally molded and manufactured using a quenching process and wire cutting to ensure high precision and high durability.

[0018] like Figure 2 The photovoltaic module frame profile load test fixture shown has a B-side limiting plate 11 that is flat and longer than the laminated limiting plate 12. The lower end of the laminated limiting plate 12 is bent into the laminated support placement part 15 to limit the profile when the load is stretched.

[0019] In this embodiment, the clamping part 2 has a straight surface design on both sides, which facilitates clamping.

[0020] like Figure 3 The present invention relates to a load testing fixture for a photovoltaic module frame profile. The clamping bolt 31 is divided into a threaded part and a clamping part. The threaded part is equipped with a nut 32 and a washer 33 for fastening the installation profile.

[0021] In this embodiment, the clamping part has a planar structure milled on both sides for easy clamping.

[0022] In this embodiment, the outer contour corners of the tooling body 1 and the clamping part 2 are designed with rounded corners. This improves safety and aesthetics, and prevents scratches on the profile.

[0023] like Figure 1 , 4The photovoltaic module frame profile load testing fixture shown is used with the working body 1 inverted and the clamping part 2 facing downwards. First, the photovoltaic module frame profile is slid into the fixture body 1 from the side, so that the A-side of the profile and the laminated part are placed in the A-side placement part 14 and the laminated part support placement part 15, respectively. Then, the profile is moved to the middle position so that the C-side punch is aligned. Next, the hoisting mechanism 3 is installed: the clamping bolt 31 is passed through the punch, and washers 33 and nuts 32 are added on both sides and tightened. Finally, the clamping part 2 is clamped at the bottom of the load testing equipment, and the clamping bolt 31 is clamped at the top to conduct the load test. Due to the contour design of the fixture, the profile is constrained at multiple points during the test, making it difficult to shift, and the test results are accurate and reliable.
