TECHNICAL FIELD
[0001] The utility model relates to a laminated frame, especially a high-strength laminated frame convenient to assemble. BACKGROUND
[0002] Double-glass solar photovoltaic panels need to be laminated during production. In order to avoid the glass from shifting during lamination, a laminated frame is introduced. The conventional laminated frame is generally a rectangular metal frame with a thickness similar to that of the double-glass photovoltaic panel assembly. The laminated frame can accommodate the double-glass photovoltaic panel assembly in its internal space. The front surface of the laminated frame is generally fixed with several flexible pull tapes, which span the internal space and are used to limit the upper surface of the double-glass photovoltaic panel assembly, ensuring that the double-glass photovoltaic panel assembly will not slide out of the internal space of the laminated frame due to vibration. The outer surface of the laminated frame is generally wrapped with a Teflon fiberglass tape, which has good lubricating and anti-sticking effects and can prevent the glue on the double-glass photovoltaic panel assembly from sticking to the laminated frame during lamination.
[0003] During production and preparation, the laminated frame generally needs to be fixed into a frame body by welding four metal plate parts and needs to be polished at the welding part. The pull tapes need to be fixed on the laminated frame by rivets, and the heads of the rivets generally need to be polished to ensure the smoothness of the surface of the laminated frame. The automation degree of the welding process and the polishing process is not high, especially the polishing process, which is mostly performed manually. Manual polishing not only increases labor costs, but also makes the quality of polishing uneven, making it difficult to control the yield and improve production efficiency. SUMMARY

[0017] The first connecting rod and the second connecting rod in the embodiment are both made of metal material, specifically stainless steel, and the right-angle connecting piece is made of engineering plastic, the melting point of most engineering plastics is above 200 degrees Celsius, while the laminating temperature of the double-glass photovoltaic panel assembly is generally 150℃±10℃, so the engineering plastic can be completely applied to the laminating process, the engineering plastic has good strength and excellent plasticity, so the right-angle connecting piece can be formed by injection molding, which has low production cost and high production efficiency. The first connecting rod and the second connecting rod generally need to go through three processes of cutting, milling and punching, among which the lap surface is formed by the milling process and the through hole is formed by the punching process, all of which are suitable for automatic production, so the production quality is relatively controllable. The two connecting rods and the right-angle connecting piece are inserted and matched, and glue can be added at the attachment part to achieve better fixation. In this way, the frame structure in the embodiment is more suitable for automatic production, the yield rate in the production process is relatively controllable, which is also conducive to improving the production efficiency and reducing the labor cost.
[0018] see Figure 2 and Figure 3The outer side of the first connecting rod is inserted with four drawstring fixers 70, and the outer side of the second connecting rod is inserted with two drawstring fixers, the drawstring fixer comprising a fixing sheet 71 and two pins 72, and the outer side of the first connecting rod is correspondingly provided with eight insertion holes 73, and the outer side of the second connecting rod is correspondingly provided with four insertion holes 73, the drawstring is located on the front surface of the frame body, and the two ends of the drawstring are fixed between the fixing sheet and the outer side of the first connecting rod or the second connecting rod and are penetrated by the pins.

The lap surface at the two ends of the connecting rod is formed with a drop from the surface, and the drop is a vertical side wall structure, and the corresponding part on the lap piece abuts against the vertical side wall structure, so that the convex portion on the corresponding lap piece can be prevented from being twisted, and when the outer shape of the lap piece is a right-angle trapezoid, the side waist line of the right-angle trapezoid is an oblique angle, so that the length of the vertical side wall is increased, and the anti-twisting effect is increased.
