Description

Technical Field

[0001] This utility model relates to the field of photovoltaic profile technology, specifically a corner bracket for photovoltaic steel frame components. Background Technology

[0002] Currently, traditional aluminum alloy is still the dominant material for module frames in the global photovoltaic market, while the proportion of new alloy steel frames is showing an increasing trend year by year. Alloy steel frame photovoltaic modules will replace aluminum alloy frame modules, which will become a new development direction for the photovoltaic module industry. Alloy steel frames are moving from the "technology verification period" to the "large-scale replacement period" and will become the preferred solution for ground-mounted power plants in the future.

[0003] Alloy steel frame components have significant advantages over aluminum frame components in terms of structural strength, bending resistance, and economic benefits. During the assembly process, the four sides of the frame are fixed together with the laminated components by corner brackets. The applicability of the corner brackets directly affects the reliability of the components. However, existing aluminum extruded corner brackets are not suitable for steel frame components. They are not sufficiently fixed during assembly and are prone to deformation and bursting, thus limiting their use. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a corner bracket for photovoltaic steel frame components, which can replace the corner brackets used in the connection of traditional photovoltaic frames. This avoids the problem that the photovoltaic components are not well fixed during installation and are easily damaged, which leads to a great limitation in their use.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A corner bracket for a photovoltaic steel frame module, comprising:

[0008] The first fastener includes a main body, an arc-shaped groove on the upper side of the main body, and a dovetail groove on the lower side of the main body.

[0009] The second fastener includes a second main body, an arc-shaped protrusion located on the upper side of the second main body and engaged in the arc-shaped slot, and a dovetail protrusion located on the lower side of the second main body and engaged in the dovetail slot.

[0010] The protective package is located at the connection between the first fixing member and the second fixing member and is bent at a 90-degree angle, with chamfers on both sides of the bend.

[0011] As a preferred embodiment of the corner bracket for a photovoltaic steel frame assembly described in this utility model, the lower side of the first fixing member and the lower side of the second fixing member are respectively provided with a first square rivet protrusion and a second square rivet protrusion.

[0012] In a preferred embodiment of the corner bracket for a photovoltaic steel frame assembly described in this utility model, the upper side of the first fixing member and the second fixing member has a first reverse tooth.

[0013] In a preferred embodiment of the corner bracket for a photovoltaic steel frame assembly described in this utility model, the upper sidewalls of the first fixing member and the second fixing member have a first folded edge.

[0014] As a preferred embodiment of the corner bracket for a photovoltaic steel frame assembly described in this utility model, the sidewalls of the first fixing member and the second fixing member have a second folded edge.

[0015] As a preferred embodiment of the corner bracket for a photovoltaic steel frame assembly described in this utility model, the first fixing member and the second fixing member are provided with a bending surface on their vertical sides, the bending surface has a plurality of second inverted teeth on its vertical surface, and the end of the bending surface has a folded ear.

[0016] Compared with the prior art, the beneficial effects of this utility model are that the corner brackets used in this photovoltaic steel frame assembly, after the first and second fixing parts are protected and connected by the 90-degree bent protective wrapping parts, are fixedly connected by the arc-shaped groove and arc-shaped protrusion, as well as the dovetail groove and dovetail protrusion, thereby ensuring the strength of the overall structure. This replaces the corner brackets used in traditional photovoltaic frame connections, avoiding the problem that the photovoltaic modules are not fixed well during installation and are easily damaged, thus resulting in great limitations in use.

[0025] Figures 1-2 The diagram shown is a structural schematic of a corner bracket for a photovoltaic steel frame assembly according to this utility model. Please refer to [link / reference]. Figures 1-2 This article provides a detailed introduction to the corner brackets used in this type of photovoltaic steel frame module.

[0026] Example 1

[0027] refer to Figures 1-2 This utility model discloses a corner bracket for a photovoltaic steel frame assembly, the main body of which includes a first fixing member 1, a second fixing member 2, and a protective wrapping member 3.

[0028] The first fastener 1 is used to connect the steel frame on one side. The first fastener 1 includes a main body 11, an arc-shaped slot 12 located on the upper side of the main body 11, and a dovetail slot 13 located on the lower side of the main body 11. The main body 11 is used to strengthen the overall structural strength. The arc-shaped slot 12 and the dovetail slot 13 are used to engage with the arc-shaped protrusion 22 and the dovetail protrusion 23 respectively, so that the connection between the first fastener 1 and the second fastener 2 is more reliable.

[0029] The second fastener 2 is used to connect the steel frame on the other side. The second fastener 2 includes a second main body 21, an arc-shaped protrusion 22 located on the upper side of the second main body 21 and snapped into the arc-shaped slot 12, and a dovetail protrusion 23 located on the lower side of the second main body 21 and snapped into the dovetail slot 13. The second main body 21 is used to strengthen the overall structural strength. The arc-shaped protrusion 22 and the dovetail protrusion 23 are used to make the overall connection more reliable after being riveted to the arc-shaped slot 12 and the dovetail slot 13 respectively.

[0030] The protective wrapping component 3 is an integrally formed structure and is used to protect the connection point after reinforcing the first fixing component 1 and the second fixing component 2. The protective wrapping component 3 is located at the connection point of the first fixing component 1 and the second fixing component 2 and is bent at a ninety-degree angle. The two sides of the protective wrapping component 3 have chamfers 31, which play a certain guiding role during the installation process.

[0031] In this embodiment, the lower side of the first fixing member 1 and the lower side of the second fixing member 2 are respectively provided with a first square rivet protrusion and a second square rivet protrusion, and the first square rivet protrusion and the second square rivet protrusion face outwards, so as to smoothly press the corner bracket into the steel frame cavity. When the corner bracket is pressed into the predetermined position, the first square rivet protrusion and the second square rivet protrusion fall into the square groove on the steel frame, which can prevent the corner bracket from sliding in the steel frame.

[0032] In this embodiment, the upper side surfaces of the first fixing member 1 and the second fixing member 2 have first back teeth 4 to prevent the corner bracket from shaking inside the cavity of the steel frame.

[0033] In this embodiment, the sidewalls of the upper sides of the first fixing member 1 and the second fixing member 2 have a first folded edge 5, which serves as an inclined guide during installation.

[0034] In this embodiment, the sidewalls of the first fixing member 1 and the second fixing member 2 have a second folded edge 6, which serves as an inclined guide during installation;

[0035] In this embodiment, the first fixing member 1 and the second fixing member 2 are provided with bending surfaces 7 on their vertical sides. The bending surfaces 7 have multiple second inverted teeth 8 on their vertical sides to facilitate the corner bracket to swing within the steel frame. The end of the bending surfaces 7 has a folded ear 9, which serves as an inclined guide during installation and prevents the bending surfaces 7 from hitting the steel frame.

[0036] In this embodiment, the first inverted tooth 4 and the second inverted tooth 8 are bidirectional fishbone structures used to improve vibration resistance in all directions;

[0037] In this embodiment, the center of the first square rivet protrusion and the second square rivet protrusion has a micropore, which is used to fill the structural adhesive during press fitting to enhance the bonding force.

[0038] In this embodiment, the specific usage process is as follows: The connection between the first fixing member 1 and the second fixing member 2 is reinforced and protected by a 90-degree bent and integrally formed protective component. The connection between the first fixing member 1 and the second fixing member 2 is more reliable under the mortise action of the arc-shaped groove 12, the arc-shaped protrusion 22, the dovetail groove 13, and the dovetail protrusion 23. The first square rivet protrusion and the second square rivet protrusion prevent the corner bracket from shaking in the cavity of the steel frame when the two ends are connected and inserted into the square groove of the steel frame cavity, thereby maintaining the overall stability during installation.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
