[0035] The following describes in detail, with reference to the accompanying drawings, the connector 10 and the photovoltaic sunroom 100 having therein, according to embodiments of the present utility model.

[0036] Reference Figures 1-4 As shown, connector 10 is used in photovoltaic sunroom 100. Photovoltaic sunroom 100 includes column 40 and chord 50. Connector 10 includes: column connecting part 1 and rod connecting part 2. Column connecting part 1 has a first connecting hole 111. The first connecting hole 111 is adapted to be connected to column 40 by a first fastener 20. Rod connecting part 2 is connected to column connecting part 1. Rod connecting part 2 has an overlap groove 24 and a second connecting hole 25. A part of chord 50 is located in the overlap groove 24. The second connecting hole 25 is adapted to be connected to chord 50 by a second fastener.

[0037] Specifically, the columns 40 of the photovoltaic sunroom 100 can be vertically fixed to the roof or the ground, and the chord 50 can be connected to the upper end of the columns 40 through the connector 10. The chord 50 can be a straight rod to form a single-slope roof photovoltaic sunroom 100 (e.g., Figure 1 As shown), the chord 50 can also be a bent bar to form a photovoltaic sunroom 100 with a gable roof (as shown). Figure 2 As shown, a photovoltaic panel 60 can be installed above the chord 50. The photovoltaic panel 60 can be used for photovoltaic power generation and has the functions of sunshade and rain protection.

[0038] The connector 10 includes a column connector 1 and a rod connector 2. The column connector 1 and the rod connector 2 can be integrally cast, or the column connector 1 and the rod connector 2 can be connected by welding, screwing, or other methods. The column connector 1 has a first connecting hole 111, which is suitable for connecting to the column 40 through a first fastener 20. That is, the first fastener 20 can pass through the first connecting hole 111 on the column connector 1 and connect to the column 40 to achieve the fixation of the column connector 1 and the column 40. The first fastener 20 can be a high-strength fastening bolt and nut, or it can be a rivet or other fastener.

[0039] The rod connecting part 2 has an overlapping groove 24 and a second connecting hole 25. When the photovoltaic sunroom 100 assembles the chord 50, a part of the chord 50 is located in the overlapping groove 24. The overlapping groove 24 can support and position the chord 50 to facilitate the assembly operation of the chord 50 and improve the assembly accuracy of the chord 50. The second connecting hole 25 is suitable for connecting to the chord 50 through a second fastener. That is, the second fastener can pass through the second connecting hole 25 on the rod connecting part 2 and connect to the chord 50 to realize the fixation of the rod connecting part 2 and the chord 50. The second fastener can be a high-strength fastening bolt and nut, or it can be a rivet or other fastener.

[0040] During the construction and installation of the photovoltaic sunroom 100, the column connecting part 1 is first fixed to the column 40 by passing the first fastener 20 through the first connecting hole 111. Then, the chord 50 is overlapped with the overlapping groove 24 of the rod connecting part 2. The rod connecting part 2 and the chord 50 are then fixed by passing the second fastener through the second connecting hole 25, so that the chord 50 is connected to the column 40 through the connector 10. The first fastener 20 and the second fastener are used to facilitate on-site assembly operations, thereby improving the installation efficiency of the photovoltaic sunroom 100. At the same time, the connection between the chord 50 and the column 40 does not require welding, thereby avoiding problems such as welding quality defects and low efficiency.

[0041] According to the embodiment of the present utility model, the connector 10 has a column connecting part 1 and a rod connecting part 2 connected together. The column connecting part 1 has a first connecting hole 111, which is connected to the column 40 through a first fastener 20. The rod connecting part 2 has an overlap groove 24 and a second connecting hole 25. A part of the chord 50 is located in the overlap groove 24. The second connecting hole 25 is connected to the chord 50 through a second fastener, so that the chord 50 is connected to the column 40 through the connector 10. The connector 10 can facilitate the assembly of the chord 50, thereby improving the installation efficiency and assembly accuracy of the photovoltaic sunroom 100.

[0042] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4As shown, the rod connection part 2 includes: a base plate 21, a first side plate 22 and a second side plate 23. The first side plate 22 and the second side plate 23 are arranged at intervals relative to each other. The base plate 21 is connected to the lower end of the first side plate 22 and the second side plate 23. The base plate 21, the first side plate 22 and the second side plate 23 are all connected to the column connection part 1 and define an overlap groove 24.

[0043] Specifically, the base plate 21, the first side plate 22, and the second side plate 23 of the rod connection part 2 can form a "U"-shaped overlapping groove 24 structure. The top of the overlapping groove 24 opposite to the base plate 21 and the side away from the column connection part 1 are both open, so that the end of the chord 50 can be easily inserted into the opening of the overlapping groove 24 during assembly. After the end of the chord 50 is inserted into the overlapping groove 24, the first side plate 22 and the second side plate 23, which are arranged at intervals, can jointly clamp the chord 50 in the overlapping groove 24 to position the assembly position of the chord 50. The base plate 21 can support the chord 50 from below, so that the construction personnel do not need to manually support the chord 50 when tightening the second fastener, reducing the labor intensity of the construction personnel and improving the assembly efficiency.

[0044] In some embodiments not shown in the figures of this utility model, the rod connecting part 2 further includes: a top plate, which is opposite to the bottom plate 21 and connected to the upper end of the first side plate 22 and the second side plate 23. The top plate, the bottom plate 21, the first side plate 22 and the second side plate 23 can jointly define a "U"-shaped overlapping groove 24 structure. The end of the string 50 can be inserted into the overlapping groove 24 from the side opening away from the column connecting part 1. The top plate and the bottom plate 21 can jointly clamp the end of the string 50 in the vertical direction, and the first side plate 22 and the second side plate 23 can jointly clamp the end of the string 50 in the horizontal direction, thereby improving the stability and accuracy of the string 50 during assembly.

[0045] In some embodiments of this utility model, at least one of the base plate 21, the first side plate 22, and the second side plate 23 has a second connecting hole 25. That is, the number of second connecting holes 25 can be one or more. When the number of second connecting holes 25 is one, the number of second fasteners assembled can be reduced, and the assembly efficiency can be improved. When the number of second connecting holes 25 is multiple, multiple second fasteners corresponding to multiple second connecting holes 25 can be used to fix the chord 50, so as to improve the connection strength and reliability between the rod connection part 2 and the chord 50.

[0046] For example, the base plate 21 has a second connecting hole 25, through which a second fastener can pass to connect with the chord 50, facilitating the assembly of the chord 50 and the rod connection part 2. Alternatively, the base plate 21, the first side plate 22, and the second side plate 23 each have a second connecting hole 25, and each second connecting hole 25 is connected to the chord 50 via a corresponding second fastener, thereby ensuring a stable and reliable connection between the chord 50 and the rod connection part 2.

[0047] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, both the first side plate 22 and the second side plate 23 have at least one second connecting hole 25, and the second connecting holes 25 on the first side plate 22 and the second connecting holes 25 on the second side plate 23 are coaxially arranged in a one-to-one correspondence. When the chord 50 is assembled with the rod connection part 2, the second fastener can pass through the two coaxially opposite second connecting holes 25 and the chord 50 in the overlapping groove 24, which helps to reduce the number of second fasteners used and improve the assembly efficiency of the chord 50.

[0048] It should be noted that the second connecting holes 25 on the first side plate 22 and the second side plate 23 are directly machined on the construction site to improve the adaptability and assembly flexibility of the connector 10. That is, when assembling the chord 50, the chord 50 can be first overlapped with the overlap groove 24 of the rod connection part 2, and then a drilling device can be used to drill holes in the normal direction (left and right direction in the figure) of the first side plate 22 and pass through the first side plate 22, the chord 50 and the second side plate 23 in sequence to form coaxial second connecting holes 25 on the first side plate 22 and the second side plate 23. Then, the rod connection part 2 and the chord 50 are fixed by passing the second fastener through the second connecting hole 25.

[0049] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the column connection 1 includes a connecting plate 11. One end face of the connecting plate 11 is adapted to fit against the column 40 in the thickness direction, and the other end face is connected to the rod connection 2. The connecting plate 11 has a first connecting hole 111. In other words, the column connection 1 can be constructed as a flat plate connecting plate 11. The end face of the connecting plate 11 facing away from the rod connection 2 can be surface-fitted against the side of the column 40. A first fastener 20 can pass through the first connecting hole 111 on the connecting plate 11 and connect to the column 40 to fix the column connection 1 to the column 40. The column connection 1 has a simple structure and is easy to assemble. Simultaneously, the surface face of the connecting plate 11 in the thickness direction fits against the surface face of the column 40, which increases the contact area between the connecting plate 11 and the column 40, thereby reducing stress concentration at the connection point and lowering the risk of local deformation of the connecting plate 11 and the column 40 under load.

[0050] In some embodiments not shown in the figures of this utility model, the column connecting part 1 further includes: a first positioning plate and a second positioning plate. The first positioning plate and the second positioning plate are arranged at intervals and connected to the two sides of the connecting plate 11. The first positioning plate, the second positioning plate and the connecting plate 11 can form a "U"-shaped connecting groove structure. The connecting groove can be sleeved on the outside of the column 40. The first positioning plate, the second positioning plate and the connecting plate 11 can be fitted to three different sides of the square tube-shaped column 40 to facilitate the assembly and positioning of the column connecting part 1 and the column 40.

[0051] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, there are multiple first connecting holes 111. Multiple first fasteners 20, which correspond one-to-one with the multiple first connecting holes 111, can be used to fix the column connecting part 1 to the column 40. That is, each first fastener 20 passes through the corresponding first connecting hole 111 and is connected to the column 40 to improve the connection strength and reliability between the column connecting part 1 and the column 40.

[0052] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, multiple first connecting holes 111 are symmetrically distributed on both sides of the position where the rod connecting part 2 is connected to the connecting plate 11, so that the first fasteners 20 in the first connecting holes 111 on both sides can evenly distribute the load, thereby improving the service life and connection reliability of the first fasteners 20.

[0053] The rod connecting part 2 is connected to the connecting plate 11 at the middle position of the connecting plate 11, and the plurality of first connecting holes 111 are evenly distributed on the upper and lower sides or the left and right sides of the middle position of the connecting plate 11. For example, referring to Figure 4 As shown, the middle part of the connecting plate 11 is connected to the rod connecting part 2. The upper side of the middle part of the connecting plate 11 has four first connecting holes 111, and the lower side of the middle part of the connecting plate 11 has four other first connecting holes 111 symmetrical to the upper side. Since the column 40 extends in the vertical direction, the multiple first connecting holes 111 symmetrically arranged in the vertical direction of the connecting plate 11 will not affect the width of the connecting plate 11 in the horizontal direction, so that the connecting plate 11 can be adapted to columns 40 of various width specifications.

[0054] According to the embodiment of this utility model, the connector 10 can be used in a photovoltaic sunroom 100. The connector 10 is located at the connection node between the column 40 and the chord 50. This connection node does not require on-site welding, thereby reducing the workload and time of assembly, improving efficiency, reducing labor costs, ensuring visual quality, avoiding welding quality defects, improving the structural safety of the photovoltaic sunroom 100, and facilitating later operation and maintenance.

[0055] Specifically, connector 10 can be manufactured in a factory and shipped to the assembly site of the photovoltaic sunroom 100. The finished connector 10 is of higher quality and strength than on-site welding, exhibiting excellent wind resistance and effectively supporting the upper chord 50 and its superstructure, demonstrating strong practicality. The first fastener 20 and the second fastener used on-site are purely bolted connections, avoiding welding and open flame operations, reducing safety risks such as fires. Simultaneously, bolted connections reduce installation time, making construction simpler, more convenient, and more efficient, optimizing project costs, improving work efficiency, and reducing construction costs.

[0056] Reference Figures 1-4 As shown, a photovoltaic sunroom 100 according to another embodiment of the present invention includes: a column 40, a chord 50 and a connector 10 as described in the above embodiment, wherein the connector 10 is connected between the column 40 and the chord 50.

[0057] According to an embodiment of the present invention, the photovoltaic sunroom 100 has a connector 10 with a column connecting part 1 and a rod connecting part 2 connected together. The column connecting part 1 has a first connecting hole 111, which is connected to the column 40 through a first fastener 20. The rod connecting part 2 has an overlap groove 24 and a second connecting hole 25. A portion of the chord 50 is located in the overlap groove 24, and the second connecting hole 25 is connected to the chord 50 through a second fastener. This allows the chord 50 to be connected to the column 40 through the connector 10. The connector 10 facilitates the assembly of the chord 50, thereby improving the installation efficiency and assembly accuracy of the photovoltaic sunroom 100.

[0058] In some embodiments of this utility model, reference is made to Figure 5 As shown, the column 40 has a limiting protrusion 401, which is engaged with the lower end of the column connecting part 1. When the connector 10 is installed on the column 40, the limiting protrusion 401 can support and position the column connecting part 1 from below. The support of the limiting protrusion 401 on the column connecting part 1 can reduce the time that construction workers need to continuously lift the connector 10, thereby reducing the labor intensity of construction workers. At the same time, the limiting of the column connecting part 1 by the limiting protrusion 401 can facilitate the rapid positioning of the column connecting part 1 and the column 40 in the vertical direction, thereby improving assembly efficiency.

[0059] In other embodiments of this utility model, reference is made to Figure 6As shown, the column 40 has a limiting groove 402, and at least a portion of the column connecting part 1 is located in the limiting groove 402. In the vertical direction, the groove wall of the limiting groove 402 is matched with the column connecting part 1 for limiting. When the connector 10 is installed on the column 40, the groove wall of the limiting groove 402 can support and position the column connecting part 1 above and below. The support of the groove wall of the limiting groove 402 for the column connecting part 1 can reduce the time that the construction personnel need to continuously lift the connector 10, thereby reducing the labor intensity of the construction personnel. At the same time, the limiting of the column connecting part 1 by the groove wall of the limiting groove 402 can facilitate the rapid positioning of the column connecting part 1 and the column 40 in the vertical direction, thereby improving the assembly efficiency.
