[0063] See Figures 1 to 10 An embodiment of this utility model provides a corner bracket 100 for connecting a frame 200. The corner bracket 100 includes a first corner bracket 110 and a second corner bracket 120. The first corner bracket 110 has a mounting groove 113. The second corner bracket 120 includes a first connecting arm 121 and a second connecting arm 122 that are connected to each other and set at an angle. The connection between the first connecting arm 121 and the second connecting arm 122 forms a corner, which is installed in the mounting groove 113. The first sidewall 111 of the mounting groove 113 is connected to the first connecting arm 121, and the second sidewall 112 of the mounting groove 113 is connected to the second connecting arm 122. The first connecting arm 121 and the second connecting arm 122 are used to connect with two adjacent frames 200.

[0064] This technical solution provides a corner bracket 100. A mounting groove 113 is constructed on a first corner bracket 110, and the corner of a second corner bracket 120 is installed within the mounting groove 113 to achieve initial connection between the first corner bracket 110 and the second corner bracket 120. The first connecting arm 121 is connected to the first sidewall 111 of the mounting groove 113, and the second connecting arm 122 is connected to the second sidewall 112 of the mounting groove 113 to fix the first corner bracket 110 and the second corner bracket 120, thus integrating the first corner bracket 110 and the second corner bracket 120 into one unit. The first connecting arm 121 and the second connecting arm 122 are connected to two adjacent frame edges 200, allowing the two adjacent frame edges 200 to be tightly assembled and connected together through the corner bracket 100, thereby achieving the encapsulation, fastening, and load-bearing functions of the frame edges 200. Through the above structure, the corner bracket 100 is set as two separate structures, resulting in fewer overall parts for the corner bracket 100, simplifying the structure and assembly process, and thus improving assembly efficiency.

[0065] In this embodiment, the mounting groove 113 on the first corner bracket 110 is a V-shaped groove, and the first sidewall 111 and the second sidewall 112 of the mounting groove 113 are arranged at a V-shaped angle, thereby forming a V-shaped mounting groove 113. The first connecting arm 121 and the second connecting arm 122 in the second corner bracket 120 are also arranged at an angle, and the angle formed between the first connecting arm 121 and the second connecting arm 122 is consistent with the angle formed between the first sidewall 111 and the second sidewall 112 of the first corner bracket 110. In this way, the corner of the second corner bracket 120 can correspond exactly to the shape of the mounting groove 113, so that the first connecting arm 121 can be connected to the first sidewall 111, and the second connecting arm 122 can be connected to the second sidewall 112, thereby realizing the mutual connection and fixation of the first corner bracket 110 and the second corner bracket 120.

[0066] It is understood that there is no limitation on the range of the included angle between the first sidewall 111 and the second sidewall 112, which can be an obtuse angle, a right angle, or an acute angle. In this embodiment, when the corner bracket 100 is applied in the photovoltaic system 1000, the corner bracket 100 is used to connect two adjacent frame 200s that are set at an angle. Usually, the included angle between the frame 200s is a right angle. Therefore, the V-shaped groove formed by the mounting groove 113 is a right angle groove. Correspondingly, the included angle between the first connecting arm 121 and the second connecting arm 122 is also a right angle.

[0067] There are no restrictions on the connection method between the first sidewall 111 and the first connecting arm 121, the second sidewall 112 and the second connecting arm 122, and it can be achieved by adhesive bonding, snap-fit ​​connection, plug-in connection or other forms.

[0068] In one embodiment, a first buckle 1111 is formed on the first sidewall 111 of the mounting groove 113, and a snap-fit ​​rib 1121 is formed on the second sidewall 112; a second buckle 1211 is provided on the first connecting arm 121, and the second buckle 1211 and the first buckle 1111 are engaged with each other; a snap-fit ​​groove 1221 is provided on the second connecting arm 122, and the snap-fit ​​rib 1121 is engaged in the snap-fit ​​groove 1221.

[0069] By constructing a first buckle 1111 on the first sidewall 111 and a second buckle 1211 on the first connecting arm 121, the first sidewall 111 and the first connecting arm 121 are connected and fixed through the mutual engagement of the first buckle 1111 and the second buckle 1211. Similarly, by constructing a snap-fit ​​rib 1121 on the second sidewall 112 and a snap-fit ​​groove 1221 on the second connecting arm 122, the second sidewall 112 and the second connecting arm 122 are connected and fixed through the mutual engagement of the snap-fit ​​rib 1121 and the snap-fit ​​groove 1221. This structural design not only ensures a reliable fit, preventing the corner bracket 100 from easily falling off, but also facilitates installation and ensures a reliable connection. This improves the tightness and strength of the connection between adjacent frame pieces 200, while also enhancing the aesthetics of the connection point between adjacent frame pieces 200.

[0070] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, a first recess 1112 is constructed on the first sidewall 111 of the mounting groove 113, and a first buckle 1111 is disposed in the first recess 1112. The first buckle 1111 includes a first connecting part 1111a and a first protrusion 1111b. One end of the first connecting part 1111a is connected to the first sidewall 111, and the other end is connected to the first protrusion 1111b. A second recess 1212 is provided on the first connecting arm 121, and a second buckle 1111 is disposed in the first sidewall 1112. 211 is disposed in the second recess 1212. The second buckle 1211 includes a second connecting part 1211a and a second protrusion 1211b. One end of the second connecting part 1211a is connected to the side wall of the second recess 1212, and the other end is connected to the second protrusion 1211b. Both the first connecting part 1211a and the second connecting part 1211a can be elastically deformed so that the first protrusion 1211b passes over the second protrusion 1211b, and the two resist and limit each other.

[0071] A first notch 1112 is provided on the first sidewall 111 of the mounting groove 113, so that the first buckle 1111 is disposed within the first notch 1112; a second notch 1212 is provided on the first connecting arm 121, and the second buckle 1211 is disposed within the second notch 1212. With the above arrangement, the first notch 1112 and the second notch 1212 together form a space for the first buckle 1111 and the second buckle 1211 to engage with each other. This ensures that after the first buckle 1111 and the second buckle 1211 engage with each other, the thickness of the arm body formed by the first sidewall 111 and the first connecting arm 121 can accommodate the cavity width of the corner bracket cavity of the frame 200, thereby making the connection between the first sidewall 111, the first connecting arm 121, and the frame 200 more secure and reliable.

[0072] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, the first buckle 1111 includes a first connecting portion 1111a and a first protrusion 1111b. By connecting one end of the first connecting portion 1111a to the first recess 1112 on the first sidewall 111, and connecting the first protrusion 1111b to the other end of the first connecting portion 1111a, the first connecting portion 1111a can be elastically deformed, so that the first protrusion 1111b can move relative to the second protrusion 1211b. The second buckle 1211 includes a second connecting portion 1211a and a second protrusion 1211b. By connecting one end of the second connecting portion 1211a to the side wall of the second recess 1212 and connecting the second protrusion 1211b to the other end of the second connecting portion 1211a, the second connecting portion 1211a can be elastically deformed. This allows the second protrusion 1211b and the first protrusion 1111b to move relative to each other when the first buckle 1111 and the second buckle 1211 are engaged. This allows the first protrusion 1111b and the second protrusion 1211b to make way for each other, so that they can pass over each other and thus achieve mutual blocking and limiting.

[0073] Furthermore, the first connecting portion 1111a and the second connecting portion 1211a are constructed as thin-walled plate-like structures, and the first protrusion 1111b and the second protrusion 1211b each protrude outward along the side of the first connecting portion 1111a and the second connecting portion 1211a. The first protrusion 1111b and the second protrusion 1211b can be triangular, ratcheted, or the like.

[0074] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the end face of the first protrusion 1111b facing away from the first connecting portion 1111a is set as an inclined surface, and the end faces of the first protrusion 1111b and the second protrusion 1211b that abut against each other are constructed as a plane perpendicular to the first connecting portion 1111a; correspondingly, the end face of the second protrusion 1211b facing away from the second connecting portion 1211a is set as an inclined surface, and the end faces of the second protrusion 1211b and the first protrusion 1111b that abut against each other are constructed as a plane perpendicular to the second connecting portion 1211a. With this configuration, when the first protrusion 1111b and the second protrusion 1211b are engaged and limited, they can be guided by the corresponding inclined surfaces, making it easier for the first protrusion 1111b and the second protrusion 1211b to pass over each other; when the first protrusion 1111b and the second protrusion 1211b abut against each other, the abutting parts are in surface contact, thereby improving the reliability of mutual limiting.

[0075] Furthermore, in this embodiment, the end of the first sidewall 111 is set as a slope, and the inclination direction of the slope of the end of the first sidewall 111 is consistent with the inclination direction of the end of the first protrusion 1111b. This is configured so that when the first latch 1111 and the second latch 1211 are engaged with each other, the end of the first sidewall 111 is prevented from interfering with the second latch 1211.

[0076] It should be noted that, in this embodiment, the first notch 1112 is formed by thinning a portion of the first sidewall 111. The second notch 1212 is formed by providing a U-shaped groove on the side of the first connecting arm 121 opposite to the first sidewall 111.

[0077] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the extending direction of the snap-fit ​​rib 1121 is consistent with the extending direction of the second sidewall 112, and the thickness of the snap-fit ​​rib 1121 is less than the thickness of the second sidewall 112; the opening of the snap-fit ​​groove 1221 faces the direction close to the corner; the snap-fit ​​rib 1121 is snapped into the snap-fit ​​groove 1221, and the side of the second sidewall 112 is flush with the side of the second connecting arm 122.

[0078] Specifically, the snap-fit ​​rib 1121 is disposed at the end of the second sidewall 112 and is aligned with the extending direction of the second sidewall 112. Furthermore, the snap-fit ​​rib 1121 can also be formed by thinning the end of the second sidewall 112. The opening of the snap-fit ​​groove 1221 is oriented towards the corner, allowing the snap-fit ​​rib 1121 to be inserted into the snap-fit ​​groove 1221. When the snap-fit ​​rib 1121 is snapped into the snap-fit ​​groove 1221, the side of the second sidewall 112 is flush with the side of the second connecting arm 122. This ensures that the overall thickness of the overlapping portion of the second sidewall 112 and the second connecting arm 122 after the snap-fit ​​rib 1121 is inserted into the snap-fit ​​groove 1221 is consistent with the thickness of the non-overlapping portion of the second connecting arm 122. In this way, when the second connecting arm 122 is connected to the frame 200, the overlapping parts of the second side wall 112 and the second connecting arm 122 can be inserted into the corner code cavity of the frame 200, thereby increasing the area of ​​the part where the second connecting arm 122 and the frame 200 are connected, thus improving the reliability of the connection between the frame 200 and the second connecting arm 122; in addition, the frame 200 can also limit the connection between the second side wall 112 and the second connecting arm 122, thereby improving the reliability of the connection between the first corner code 110, the second corner code 120 and the frame 200.

[0079] like Figures 5 to 8As shown, in one embodiment, both the first connecting arm 121 and the second connecting arm 122 are provided with mounting notches; the end of the first sidewall 111 is located in the mounting notch on the first connecting arm 121; the end of the second sidewall 112 is located in the mounting notch on the second connecting arm 122; wherein, the end of the first sidewall 111 and the first connecting arm 121 are used together to engage with the corner code cavity of the frame 200; the end of the second sidewall 112 and the second connecting arm 122 are used together to engage with the corner code cavity of the frame 200.

[0080] By providing right-angled mounting notches on the first connecting arm 121 and the second connecting arm 122, and placing the ends of the first side wall 111 and the second side wall 112 into the mounting notches, the first side wall 111 and the first connecting arm 121 overlap, thereby limiting the first side wall 111 and the first connecting arm 121 by the cavity wall of the corner code cavity of the frame 200; correspondingly, the second side wall 112 and the second connecting arm 122 are limited by the cavity wall of the corner code cavity of the frame 200.

[0081] like Figures 5 to 8 As shown, in one embodiment, the first sidewall 111 and the second sidewall 112 are provided with first adhesive holes 1113, and the first connecting arm 121 and the second connecting arm 122 are provided with second adhesive holes 1213; when the corner of the second corner bracket 120 is installed in the mounting groove 113, the first adhesive holes 1113 and the second adhesive holes 1213 correspond to each other.

[0082] Specifically, the first adhesive holes 1113 on the first sidewall 111 and the second sidewall 112 penetrate the first sidewall 111 and the second sidewall 112 respectively along the thickness direction of the first sidewall 111 and the second sidewall 112; correspondingly, the second adhesive holes 1213 on the first connecting arm 121 and the second connecting arm 122 penetrate the first connecting arm 121 and the second connecting arm 122 along the thickness direction of the first connecting arm 121 and the second connecting arm 122. When the snap-fit ​​rib 1121 is engaged in the snap-fit ​​groove 1221, the first adhesive hole 1113 on the first sidewall 111 corresponds to the second adhesive hole 1213 on the first connecting arm 121; the first adhesive hole 1113 on the second sidewall 112 corresponds to the second adhesive hole 1213 on the second connecting arm 122. By applying adhesive to the first adhesive hole 1113 and the second adhesive hole 1213, the first sidewall 111 and the first connecting arm 121 are connected by adhesive in addition to being engaged by the first snap-fit ​​rib 1111 and the second snap-fit ​​1211; the second sidewall 112 and the second connecting arm 122 are also connected by adhesive in addition to being fixedly connected by the snap-fit ​​rib 1121 and the snap-fit ​​groove 1221, thereby improving the reliability of the connection between the second sidewall 112 and the second connecting arm 122.

[0083] like Figures 5 to 8 As shown, in another embodiment, a first adhesive hole 1113 can be directly provided on the first sidewall 111 and the second sidewall 112, and a second adhesive hole 1213 can be provided on the first connecting arm 121 and the second connecting arm 122. When the first corner bracket 110 and the second corner bracket 120 are engaged with each other, adhesive is applied into the first adhesive hole 1113 and the second adhesive hole 1213 to achieve the connection between the first sidewall 111 and the first connecting arm 121, and between the second sidewall 112 and the second connecting arm 122. Since the corner bracket cavity of the frame 200 is engaged with the outside of the first sidewall 111 and the first connecting arm 121, and the corner bracket cavity of the other frame 200 is engaged with the outside of the second sidewall 112 and the second connecting arm 122, the frame 200 can be used to limit the first sidewall 111 and the first connecting arm 121, as well as the second sidewall 112 and the second connecting arm 122.

[0084] In another embodiment, to simplify the structure, the portion of the second connecting arm 122 that overlaps with the second sidewall 112 is thinned so that the second sidewall 112 and the second connecting arm 122 overlap. Then, by providing adhesive holes on the second connecting arm 122 and the second sidewall 112, the second sidewall 112 and the second connecting arm 122 are connected by adhesive dispensing. Then, by connecting the frame 200 with the second sidewall 112 and the second connecting arm 122, the three form a mortise and tenon structure, making it less likely for the photovoltaic module 20 to fall off or detach during service.

[0085] It is understood that, in another embodiment, first adhesive holes 1113 may only be provided on the first sidewall 111 and the second sidewall 112 of the first corner bracket 110, while second adhesive holes 1213 may not be provided on the first connecting arm 121 and the second connecting arm 122 of the second corner bracket 120. After the first corner bracket 110 and the second corner bracket 120 are connected, adhesive only needs to be applied to the first adhesive holes to achieve bonding between the first sidewall 111 and the first connecting arm 121, and between the second sidewall 112 and the second connecting arm 122. This approach achieves the connection of the first corner bracket 110 and the second corner bracket 120 while reducing the steps required to create adhesive holes in the first connecting arm 121 and the second connecting arm 122, thereby reducing production costs.

[0086] like Figure 3 , Figure 5 and Figure 10As shown, in one embodiment, the first corner code 110 further includes a first limiting plate 114 and a second limiting plate 115, which are respectively disposed at opposite ends of the mounting groove 113; the first limiting plate 114 is connected to one end of the first side wall 111 and the second side wall 112; the second limiting plate 115 is connected to the other end of the first side wall 111 and the second side wall 112; wherein, the first limiting plate 114 and the second limiting plate 115 are used to limit the opposite sides of the corner of the second corner code 120.

[0087] By setting a first limiting plate 114 and a second limiting plate 115 at opposite ends of the mounting groove 113, the first limiting plate 114 and the second limiting plate 115 limit the opposite sides of the corner of the second corner bracket 120, thereby further improving the reliability of the connection between the first corner bracket 110 and the second corner bracket 120. Furthermore, through the above arrangement, after the frame 200 sets are assembled, only the first side plate, the second side plate, the first limiting plate 114, and the second limiting plate 115 of the first corner bracket 110 are exposed, making the outer casing a single unit with uniform color, which is more aesthetically pleasing than a three-section structure. The first corner bracket 110, as a single structural component, can have its shape customized. For example, the connection points between the first and second side plates, the connection points between the first limiting plate 114 and the first and second side plates, and the connection points between the second limiting plate 115 and the first and second side plates can all be rounded or chamfered, thus preventing scratches to workers during installation. In addition, company logos and other graphics can be placed on the exposed side of the first corner code 110.

[0088] like Figure 5 and Figure 10 As shown, in one embodiment, the first corner code 110 further includes a limiting body 116, which is connected to the side of the first limiting plate 114. The limiting body 116 and the first limiting plate 114 together form a receiving groove, which is used to receive any corner of the photovoltaic module 20.

[0089] Specifically, the limiting body 116 includes an extension plate connected to the outer edge of the first limiting plate 114 and extending in a direction away from the first limiting plate 114, and a third limiting plate connected to the extension plate. The extension plate is a V-shaped plate, with two segments corresponding to the first sidewall 111 and the second sidewall 112, respectively. The third limiting plate is substantially parallel to the first limiting plate 114 to form a receiving groove.

[0090] It should be noted that for the full-screen photovoltaic module 20, the frame 200 has no A-side, meaning the side of the frame 200 is not located on the light-facing surface of the photovoltaic module 20. Therefore, the frame 200 is connected to the backlight surface of the photovoltaic module 20. This leaves the four corners of the photovoltaic module 20 completely exposed. Therefore, by configuring the first corner bracket 110 as described above, after the corner bracket 100 is connected to two adjacent frames 200, the corner of the photovoltaic module 20 corresponding to the corner bracket 100 is placed within the receiving groove, thus protecting the corners of the photovoltaic module 20. This is especially important during transportation, as the corner bracket 100 protects the four corners of the photovoltaic module 20 to prevent damage during transport.

[0091] like Figure 3 , Figure 5 ,and Figure 10 As shown, in one embodiment, the first limiting plate 114 and the second limiting plate 115 are each provided with a plurality of spaced-apart protrusions 1141 on their respective sides. By providing a plurality of spaced-apart protrusions 1141 on the first limiting plate 114 and the second limiting plate 115, the roughness of the first limiting plate 114 and the second limiting plate 115 is increased. This allows the first limiting plate 114 of one photovoltaic module 20 to abut against the second limiting plate 115 of another photovoltaic module 20 during transportation, and the spaced-apart protrusions 1141 increase the friction between the first limiting plate 114 and the second limiting plate 115, thereby preventing the photovoltaic modules 20 from moving relative to each other.

[0092] The specific structure of the raised ribs 1141 is not limited. In this embodiment, the back of the multiple raised ribs 1141 is set in a form in which multiple raised ribs 1141 are spaced apart and sequentially translated outward from the center of the photovoltaic module 20. In addition, the back of the raised ribs 1141 is constructed in a V-shape.

[0093] like Figure 5 and Figure 10 As shown, in one embodiment, the outer edges of both the first limiting plate 114 and the second limiting plate 115 extend beyond the outer surfaces of the first sidewall 111 and the second sidewall 112. By configuring the outer edges of both the first limiting plate 114 and the second limiting plate 115 to extend beyond the outer surfaces of the first sidewall 111 and the second sidewall 112, the area of ​​the first limiting plate 114 and the second limiting plate 115 is increased, thereby improving the pressure-bearing capacity of the corner bracket 100.

[0094] In one embodiment, two adjacent outer edges of the first limiting plate 114 protrude away from the second limiting plate 115 to form the aforementioned limiting body 116. The limiting body 116 has an insertion protrusion 1161 on its side away from the second limiting plate 115. The outer edge of the second limiting plate 115 has an insertion groove 1151 corresponding to the insertion protrusion 1161. In the two photovoltaic modules 20 stacked vertically, the insertion protrusion 1161 on the first limiting plate 114 of one photovoltaic module 20 is inserted into the insertion groove 1151 on the second limiting plate 115 of the other photovoltaic module 20.

[0095] In this embodiment, the limiting body 116 is constructed as a V-shaped structure. One end of the limiting body 116 is connected to the first limiting plate 114. The V-shaped limiting body 116 and the first limiting plate 114 enclose a concave space, which is a receiving groove for accommodating the photovoltaic module 20. By providing an insertion protrusion 1161 at the end of the limiting body 116 and an insertion groove 1151 on the second limiting plate 115, when the photovoltaic modules 20 are stacked together during transportation, the insertion protrusion 1161 on the corner bracket 100 corresponding to the lower photovoltaic module 20 is inserted into the insertion groove 1151 on the upper photovoltaic module 20. This limits and protects the stacked photovoltaic modules 20, preventing them from bumping or shifting, and thus ensuring the safe transportation of the photovoltaic modules 20.

[0096] It should be noted that the first corner bracket 110 provided in this embodiment is formed by die casting, and its material can be aluminum alloy. The second corner bracket 120 is formed into a profile by extrusion, and then cut to a size that matches the first corner bracket 110.

[0097] like Figure 11 As shown, one embodiment of the present invention also provides a border component 10, which includes the corner bracket 100 as described above. The border component 10 also includes a plurality of borders 200 connected end to end. Any two adjacent borders 200 are connected by the corner bracket 100 and are set at an angle.

[0098] By connecting the corner bracket 100 with the frame 200 as described above, a frame assembly 10 is formed, which is applied in the photovoltaic module 20. It is understood that the frame assembly 10 provided in this embodiment can be applied to a general photovoltaic system 1000 or to a full-screen photovoltaic module 20. By applying the corner bracket 100 to the frame assembly 10, the first connecting arm 121 and the second connecting arm 122 are connected to two adjacent frames 200, so that the two adjacent frames 200 are tightly assembled and connected together through the corner bracket 100, thereby realizing the encapsulation, fastening, and load-bearing functions of the frame 200. Through the above structure, the corner bracket 100 is set as two separate structures, resulting in fewer overall parts for the corner bracket 100, simplifying the structure and assembly process of the corner bracket 100, thereby improving assembly efficiency.

[0099] In one embodiment, the inner sides of the first connecting arm 121 and the second connecting arm 122 are provided with a first limiting structure 1214 that is concave and convex in sequence; the frame 200 is provided with a corner code cavity, and the cavity wall of the corner code cavity is provided with a second limiting structure that is concave and convex in sequence; wherein, the first limiting structure 1214 and the second limiting structure are concave and convex in cooperation with each other and mutually limit each other.

[0100] By providing a first limiting structure 1214 with concave and convex connections on the inner sides of the first connecting arm 121 and the second connecting arm 122, and a second limiting structure with concave and convex connections on the cavity wall of the corner code cavity of the frame 200, the first limiting structure 1214 and the second limiting structure cooperate with each other to achieve mutual limiting, thereby improving the reliability of the connection between the first connecting arm 121, the second connecting arm 122 and the frame 200, and preventing the corner code 100 from falling off.

[0101] like Figures 11 to 14 As shown, an embodiment of the present invention also provides a photovoltaic system 1000, which includes the frame component 10 as described above, and the photovoltaic system 1000 also includes a photovoltaic module 20. The frame component 10 is disposed on the four edges of one side of the photovoltaic module 20.

[0102] By applying the frame 200 as described above to the photovoltaic module 20, the reliability and stability of the connection between the photovoltaic module 20 and the frame assembly 10 in the photovoltaic system 1000 are improved.

[0103] The assembly method of the corner bracket 100 provided by this utility model is as follows:

[0104] Align the corner of the second corner bracket 120 with the mounting groove 113 of the first corner bracket 110, wherein the opening of the snap-fit ​​groove 1221 on the second corner bracket 120 corresponds to the snap-fit ​​protrusion 1121 on the first corner bracket 110, and the second latch 1211 on the second corner bracket 120 corresponds to the first latch 1111 on the first corner bracket 110. Then, push the corner of the second corner bracket 120 into the mounting groove 113 of the first corner bracket 110. This achieves the snap-fit ​​between the snap-fit ​​protrusion 1121 and the snap-fit ​​groove 1221, and the mutual snap-fit ​​between the first latch 1111 and the second latch 1211, thereby achieving the connection between the first corner bracket 110 and the second corner bracket 120. Then, apply glue into the first glue hole 1113 and the second glue hole 1213 to further improve the reliability of the connection between the first corner bracket 110 and the second corner bracket 120.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
