[0041] 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.

[0042] Reference Figures 1-11As shown, connector 10 is used in photovoltaic sunroom 100. Photovoltaic sunroom 100 includes: upper chord 50, lower chord 60 and at least one web member 70. One end of web member 70 is connected to upper chord 50 through connector 10, and the other end of web member 70 is connected to lower chord 60 through another connector 10. Connector 10 includes: first connecting plate 1 and second connecting plate 2. First connecting plate 1 has a first connecting hole 11, which is adapted to be connected to upper chord 50 or lower chord 60 through a first fastener 20. Second connecting plate 2 is connected to first connecting plate 1 at an angle. Second connecting plate 2 has a second connecting hole 21, which is adapted to be connected to web member 70 through a second fastener.

[0043] Specifically, the photovoltaic sunroom 100 can be installed on a roof or the ground. The upper chord 50 and the lower chord 60 can be connected to two columns 40 spaced apart in the front-rear direction of the photovoltaic sunroom 100. The upper chord 50, the lower chord 60, and at least one web member 70 can form the roof truss structure of the photovoltaic sunroom 100. The upper chord 50 and the lower chord 60 can be straight members to form a single-slope roof photovoltaic sunroom 100 (e.g., Figure 1 As shown), the upper chord 50 and lower chord 60 can also be bent bars to form a photovoltaic sunroom 100 with a gable roof (as shown). Figure 2 As shown, a photovoltaic panel 80 can be installed above the upper chord 50. The photovoltaic panel 80 can be used for photovoltaic power generation and has the functions of sunshade and rain protection.

[0044] The upper chord 50 can be located above the lower chord 60, and the upper chord 50 and the lower chord 60 can be arranged in parallel. The web members 70 are connected between the upper chord 50 and the lower chord 60. The number of web members 70 can be one or more. The upper chord 50, the lower chord 60 and the web members 70 between them can jointly form a truss structure. The number and angle of the web members 70 can be set according to the span of the upper chord 50 and the lower chord 60 in the front-back direction, so that the truss structure can have good bending and shear resistance, and can give full play to the strength of the material, thus making it suitable for photovoltaic sunroom 100 roof structures of various spans.

[0045] One end of the web member 70 is connected to the upper chord 50 through a connector 10, and the other end of the web member 70 is connected to the lower chord 60 through another connector 10. That is to say, both the upper chord 50 and the lower chord 60 are connected to the web member 70 through corresponding connectors 10. The connectors 10 are the connection nodes at both ends of the web member 70.

[0046] The connector 10 includes a first connecting plate 1 and a second connecting plate 2. The first connecting plate 1 has a first connecting hole 11, which is adapted to be connected to the upper chord 50 or the lower chord 60 through a first fastener 20. That is, the first fastener 20 can be inserted through the first connecting hole 11 of the first connecting plate 1 to connect to the upper chord 50 or the lower chord 60 to fix the first connecting plate 1 to the upper chord 50 or the lower chord 60. The first fastener 20 may include a high-strength U-bolt 201 and a matching nut. The first fastener 20 may also be a rivet, a fastening bolt, and a nut.

[0047] The second connecting plate 2 and the first connecting plate 1 can be integrally cast, or the second connecting plate 2 and the first connecting plate 1 can be connected by welding, screwing or other means. The second connecting plate 2 and the first connecting plate 1 are connected at an angle, that is, a part of the second connecting plate 2 is separated from the first connecting plate 1, so as to facilitate the assembly of the web member 70 and the second connecting plate 2.

[0048] The second connecting plate 2 has a second connecting hole 21, which is adapted to be connected to the web member 70 by a second fastener. That is, the second fastener can be connected to the web member 70 through the second connecting hole 21 on the second connecting plate 2 to achieve the fixation of the second connecting plate 2 and the web member 70. The second fastener can be a high-strength fastening bolt and nut, or it can be a rivet or other fastener.

[0049] In some embodiments, the second connecting plate 2 is adapted to be inserted into the web member 70, that is, the end of the web member 70 can be inserted into the second connecting plate 2 to increase the connection area between the web member 70 and the second connecting plate 2, thereby improving the stability and reliability of the connection between the two.

[0050] During the construction and installation of the photovoltaic sunroom 100, the first connecting plate 1 is first installed on the upper chord 50 or the lower chord 60 through the first connecting hole 11 using the first fastener 20. At least one connector 10 is installed on both the upper chord 50 and the lower chord 60. Then, the web member 70 is inserted into the second connecting plate 2 on the upper chord 50 and the second connecting plate 2 on the lower chord 60 according to predetermined positions and angles. The web member 70 and the second connecting plate 2 are then fixed by passing the second fastener through the second connecting hole 21, thus assembling both ends of the web member 70 with the second connecting plate 2 on the upper chord 50 and the lower chord 60 respectively, connecting the web member 70 between the upper chord 50 and the lower chord 60. The use of the first and second fasteners on the construction site, which facilitate assembly, improves the installation efficiency of the photovoltaic sunroom 100. Furthermore, the connection between the web member 70 and the upper chord 50 and lower chord 60 does not require welding, avoiding problems such as welding quality defects and low efficiency.

[0051] According to the connector 10 of this utility model embodiment, the first connecting plate 1 and the second connecting plate 2 are connected at an included angle. The first connecting plate 1 has a first connecting hole 11, which is connected to the upper chord 50 or the lower chord 60 through a first fastener 20. The second connecting plate 2 has a second connecting hole 21, which is connected to the web member 70 through a second fastener. The two ends of the web member 70 can be connected to the upper chord 50 and the lower chord 60 respectively through the corresponding connector 10. The connector 10 can facilitate the assembly of the web member 70, thereby improving the installation efficiency and assembly accuracy of the photovoltaic sunroom 100.

[0052] In some embodiments of this utility model, reference is made to Figures 3-11 As shown, the angle between the second connecting plate 2 and the first connecting plate 1 is a right angle. That is, the thickness direction of the second connecting plate 2 is perpendicular to the thickness direction of the first connecting plate 1, so that the second connecting plate 2 has equal space on both sides of its thickness direction, reducing the risk of the web member 70 interfering with the first connecting plate 1 on both sides of the thickness direction of the second connecting plate 2.

[0053] In some embodiments of this utility model, reference is made to Figures 8-11 As shown, the second connecting plate 2 has a plurality of spaced second connecting holes 21. Each second connecting hole 21 can be connected to the same or different web members 70 through a corresponding second fastener. That is, when multiple second connecting holes 21 are connected to the same web members 70 through corresponding second fasteners, the connection strength and reliability between the web members 70 and the second connecting plate 2 are improved. When each second connecting hole 21 is connected to different web members 70 through corresponding second fasteners, the second connecting plate 2 of one connector 10 can fix multiple web members 70, thereby reducing the number of connectors 10 used in the photovoltaic sunroom 100 and reducing the material and construction costs of the photovoltaic sunroom 100.

[0054] In some embodiments of this utility model, reference is made to Figure 6 and Figure 10 As shown, the width of the second connecting plate 2 gradually increases in the direction close to the first connecting plate 1. The second connecting plate 2 can be a plate with a triangular plate, trapezoidal plate, or other similar structure. The bottom of the second connecting plate 2 is wider than the bottom of the first connecting plate 1, which can increase the connection area between the second connecting plate 2 and the first connecting plate 1, improve the connection reliability between the first connecting plate 1 and the second connecting plate 2, and reduce the risk of breakage at the connection point. The top of the second connecting plate 2 is narrower than the top of the first connecting plate 1, so as to reduce the material used in the second connecting plate 2, achieve the weight reduction of the second connecting plate 2, and reduce the cost of the second connecting plate 2.

[0055] In some embodiments of this utility model, the first connecting plate 1 has a plurality of first connecting holes 11, and the first fasteners 20 can correspond one-to-one with the first connecting holes 11. The first connecting plate 1 can be connected to the upper chord 50 or the lower chord 60 by a plurality of first fasteners 20 that are the same number as the plurality of first connecting holes 11, so as to improve the reliability of the connection between the first connecting plate 1 and the upper chord 50 or the lower chord 60.

[0056] In other embodiments of this utility model, reference is made to Figures 3-7 As shown, the first connecting plate 1 has multiple first connecting holes 11. The first fastener 20 pieces can correspond to at least two of the first connecting holes 11 to reduce the number of first fasteners 20. For example, the first fastener 20 includes: a U-bolt 201, a first nut 202 and a second nut 203. The U-bolt 201 is sleeved on the upper chord 50 or the lower chord 60, and both ends of the U-bolt 201 pass through the corresponding first connecting holes 11 of the first connecting plate 1. The first nut 202 and the second nut 203 are respectively threaded to both ends of the U-bolt 201.

[0057] In some embodiments of this utility model, reference is made to Figure 7 and Figure 11 As shown, multiple first connecting holes 11 are symmetrically distributed on both sides of the connection position between the second connecting plate 2 and the first connecting plate 1, so that the first fasteners 20 in the first connecting holes 11 on both sides can evenly distribute the load, thereby improving the service life and connection reliability of the first fasteners 20.

[0058] The second connecting plate 2 is connected to the first connecting plate 1 at the middle position of the first connecting plate 1. Multiple first connecting holes 11 are evenly distributed on both sides of the middle position of the first connecting plate 1. The line connecting two symmetrical first connecting holes 11 on both sides is perpendicular to the second connecting plate 2, so as to facilitate the processing, manufacturing and assembly of the connector 10.

[0059] 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 nodes at both ends of the web member 70. 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.

[0060] 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 transferring loads between the upper chord 50, web member 70, and lower chord 60, 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.

[0061] Reference Figures 1-11 As shown, a photovoltaic sunroom 100 according to another embodiment of the present invention includes: an upper chord 50, a lower chord 60, at least one web member 70, and a connector 10 as described in the above embodiment. One end of the web member 70 is connected to the upper chord 50 through a connector 10, and the other end of the web member 70 is connected to the lower chord 60 through another connector 10.

[0062] According to the embodiment of the present utility model, in the photovoltaic sunroom 100, the first connecting plate 1 and the second connecting plate 2 of the connector 10 are connected at an included angle. The first connecting plate 1 has a first connecting hole 11, which is connected to the upper chord 50 or the lower chord 60 through a first fastener 20. The second connecting plate 2 has a second connecting hole 21, which is inserted into the web member 70. The second connecting hole 21 is connected to the web member 70 through a second fastener. The two ends of the web member 70 can be connected to the upper chord 50 and the lower chord 60 respectively through the corresponding connector 10. The connector 10 can facilitate the assembly of the web member 70, thereby improving the installation efficiency and assembly accuracy of the photovoltaic sunroom 100.

[0063] In some embodiments of this utility model, reference is made to Figure 5 As shown, both ends of the web member 70 have insertion slots 701, and the second connecting plate 2 is inserted into the insertion slots 701 to increase the connection area between the second connecting plate 2 and the web member 70 and increase the connection reliability between the second connecting plate 2 and the web member 70.

[0064] In some embodiments of this utility model, reference is made to Figure 5 As shown, in the thickness direction of the second connecting plate 2 ( Figure 5 (in the left and right directions), the thickness of the second connecting plate 2 is less than or equal to the width of the insertion slot 701.

[0065] Specifically, the width direction of the insertion slot 701 is the same as the thickness direction of the second connecting plate 2, that is, the thickness of the second connecting plate 2 is the same as the thickness direction of the second connecting plate 2. Figure 5 The dimensions in the left-right direction, the slot width of the insertion slot 701 is the same as the dimensions of the insertion slot 701 in the left-right direction. Figure 5Before tightening the second fastener, the thickness of the second connecting plate 2 is less than or equal to the width of the insertion groove 701. After the second connecting plate 2 is inserted into the insertion groove 701, the groove walls on both sides of the insertion groove 701 form a transition or clearance fit with the second connecting plate 2. The friction between the groove walls on both sides of the insertion groove 701 and the second connecting plate 2 is small. At this time, the web rod 70 can be rotated to adjust the web rod 70 to a preset angle (vertical or inclined). Then the second fastener is tightened. The second fastener can press the web rod 70 so that the groove walls on both sides of the insertion groove 701 abut against the second connecting plate 2 and form an interference fit. When the web rod 70 has a tendency to rotate, the friction between the groove walls on both sides of the insertion groove 701 and the second connecting plate 2 is large to prevent the web rod 70 from rotating after assembly.

[0066] In some embodiments of this utility model, reference is made to Figures 3-5 As shown, the first fastener 20 includes: a U-bolt 201, a first nut 202 and a second nut 203. The U-bolt 201 is sleeved on the upper chord 50 or the lower chord 60, and both ends of the U-bolt 201 pass through the first connecting holes 11 corresponding to the first connecting plate 1. The first nut 202 and the second nut 203 are respectively threaded to both ends of the U-bolt 201.

[0067] Understandably, since the U-bolt 201 is fitted onto the upper chord 50 or lower chord 60, when the first nut 202 and the second nut 203 are not tightened on the U-bolt 201, the first connecting plate 1 forms a movable pre-assembly with the upper chord 50 or lower chord 60 through the U-bolt 201. This allows the first connecting plate 1 to be pushed, causing the first connecting plate 1 and the U-bolt 201 to slide relative to the upper chord 50 or lower chord 60, facilitating the adjustment of the position of the first connecting plate 1. After the first connecting plate 1 is adjusted to the preset position, the first nut 202 and the second nut 203 can be tightened on the U-bolt 201, so that the U-bolt 201 is clamped onto the upper chord 50 or lower chord 60, thereby achieving the fixation of the first connecting plate 1 to the upper chord 50 or lower chord 60.
