Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, in particular to a quick-installation and quick-disassembly type photovoltaic frame. Background Art

[0002] At present, the frames constituting photovoltaic modules generally use conventional right-angle corner codes to cooperate with conventional frames for framing. After the framing is completed, it is locked to form a firm installation structure in which the corner codes are difficult to disassemble. However, due to the aging, damage, etc. of the modules during long-term use, it is necessary to recycle the photovoltaic modules. For the frames with the above installation structure, since the corner codes are stuck inside the long and short frames and cannot be released, it is difficult to disassemble the frames. Equipment such as a cutting machine is required to achieve the frame disassembly treatment with a certain degree of damage, which cannot meet the requirements of convenient, efficient and as complete frame disassembly as possible.

The corner ends of the short frames are in close contact with the corner ends of the long frames. An irregular corner code is connected between the corner ends of the short frames and the corner ends of the long frames. The corner end of the short frame has a first hypotenuse, and the corner end of the long frame has a second hypotenuse that matches the first hypotenuse. The first hypotenuse includes an inner concave arc on the outside and a 45-degree hypotenuse on the inside. The second hypotenuse includes an outer convex arc on the outside and a 45-degree hypotenuse on the inside. The inner concave arc matches the outer convex arc.

[0005] The irregular corner code includes a right-angle body. Both ends of the right-angle body are respectively bent inward to form clamping hooks, and the clamping hooks are correspondingly connected to the inner side surfaces of the short frame and the long frame.

[0006] Rectangular clamping holes are opened on the inner side surfaces of the short frame and the long frame, and the clamping hooks are clamped into the rectangular clamping holes.

[0016] The present utility model will now be further described in detail in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0017] As Figure 1 shown, a quick-installation and quick-disassembly type photovoltaic frame is composed of two short frame edges 1 and two long frame edges 2 spliced together. The short frame edges 1 and the long frame edges 2 are both made of standard profiles. The corner ends of the short frame edges 1 are fitted with the corner ends of the long frame edges 2 to form a whole photovoltaic frame.

[0018] As Figure 2 , Figure 3 , Figure 5 shown, specifically, the corner end of the short frame edge 1 profile has a first bevel edge 1-1 cut out, and the first bevel edge 1-1 includes an outer concave arc edge 1-2 and an inner 45-degree bevel edge. The corner end of the long frame edge 2 has a second bevel edge 2-1 cut out, and the second bevel edge 2-1 includes an outer convex arc edge 2-2 and an inner 45-degree bevel edge. During installation, the outer convex arc edge 2-1 is fitted and embedded into the inner concave arc edge 1-2, and the 45-degree bevel edge of the first bevel edge 1-1 is fitted with the 45-degree bevel edge of the second bevel edge 2-1.

[0019] The short side frame 1 and the long side frame 2 are spliced through the first bevel edge 1-1 and the second bevel edge 2-1, and a good mortise and tenon fit is formed by relying on the concave arc edge 1-2 to embed into the convex arc edge 2-2, preventing tangential translation of the splicing surface. After the photovoltaic frame is assembled, the displacement of the splicing surface is restricted, increasing the stability of the frame.

[0020] As Figure 4 shown, the corners of the short side frame 1 and the long side frame 2 are fixedly connected by a special-shaped corner code 3. The special-shaped corner code 3 includes a right-angle body 3-1, and both ends of the right-angle body 3-1 are respectively provided with clamping hooks 3-2 formed by bending inward; rectangular clamping holes 4 are opened on the inner side surfaces of both ends of the short side frame 1 and the inner side surfaces of both ends of the long side frame 2. When fixing, the clamping hooks 3-2 are clamped into the rectangular clamping holes 4 and protrude from the inner side surfaces of the short side frame 1 and the long side frame 2.

[0021] The above-mentioned rectangular clamping holes 4 can be correspondingly designed according to the structure of the clamping hooks 3-2 at both ends of the special-shaped corner code 3, and the hole shape includes but is not limited to a rectangle.

[0022] As Figure 6 shown, before the frame combination, the special-shaped corner code 3 is driven into the short side frame 1 in advance. Through the cooperation of the clamping hook 3-2 at one end of the special-shaped corner code 3, it is clamped into the rectangular clamping hole 4 on the short side frame 1 to realize the connection between the short side frame 1 and the special-shaped corner code 3. The other end of the special-shaped corner code 3 is inserted and matched with the rectangular clamping hole 4 at one end of the long side frame 2, and finally a set of photovoltaic frames is assembled. Due to the clamping hooks 3-2 with a protruding structure at both ends of the special-shaped corner code 3, it has the effect of convenient disassembly.

[0023] The utility model can solve the problem of force slippage in the tangential direction existing in the process of assembling photovoltaic frames for a long time by the fitting of the convex arc edge 2-2 and the concave arc edge 1-2, increasing the stability after the frame combination, improving the mechanical properties at the long and short frames of the component, and improving the load-bearing capacity of the component; secondly, by using the clamping hooks 3-2 at both ends of the special-shaped corner code 3, which are respectively matched with the rectangular clamping holes 4 at both ends of the short side frame 1 and the long side frame 2, compared with the combination of conventional frames and corner codes, the frame can be loosened by knocking the special-shaped corner code 3 to achieve the purpose of rapid disassembly; finally, in terms of the frame appearance, the splicing of the short side frame 1 and the long side frame 2 adopts a mortise and tenon structure, which has aesthetic characteristics and increases the beauty of the component appearance.

[0024] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
