[0033] The utility model will be described in detail below in combination with the drawings and specific embodiments.

[0034] The utility model provides a kind of inclined beam ridge connecting structure, as shown in Figures 2 to 8 , it include at least two inclined beams 1 and two connecting heads 2, the inner end of two inclined beams 1 is connected by connecting head 2, to form herringbone structure at the ridge of photovoltaic support.Equivalently, the outer end of two connecting heads 2 is connected with the inclined beam 1 of same side respectively, and the inner end of two connecting heads 2 is connected with each other by fastener, to connect two inclined beams 1.

[0035] The inclined beam 1 of the scheme is hollow structure, but this design is not absolute necessary limiting condition.It can be flexibly adjusted according to actual application demand.The main advantage of hollow structure is that it is beneficial to greatly reduce overall weight, to improve the carrying and installation efficiency of photovoltaic support;Meanwhile, hollow design can effectively improve the utilization rate of material, reduce cost benefit, so that the manufacture of photovoltaic support is more economical and efficient.

[0036] More critical is that the outer periphery of the main body 11 of inclined beam 1 is equipped with T-shaped groove 12.As Figure 2 、 Figure 3 And Figure 5 It is shown that groove 12 extends along the length direction of inclined beam 1, and the two sides of groove 12 have lateral notch for the head of T-shaped bolt 4 to enter.In the embodiment, inclined beam 1 is cubic, and one groove 12 can be selected on each of the two opposite sides of inclined beam 1 to form simple and effective connecting structure;Or, to further enhance the stability of connection, one groove 12 can also be selected on each of the three side surfaces of inclined beam 1, which not only can provide more T-shaped bolt 4 connection point, but also can disperse stress in multiple directions, improve the carrying capacity and stability of the whole connecting structure.

[0037] The structure of a T-shaped bolt 4 used in the case is as shown in Figure 4 And Figure 8As shown, the head is a parallelepiped, in which one group of parallel sides is long and the other two groups are short. The T-shaped bolt 4 is matched with the groove 12 on the inclined beam 1 in the following way: the head of the T-shaped bolt 4 is slid into the lateral slot of the groove 12, and then is rotated by a certain angle so that the head is clamped in the groove 12.

[0038] The specific structure of the connecting head 2 is that the cross section of the connecting head 2 is U-shaped, which enables the inclined beam 1 to be well embedded and carried in the U-shaped connecting head 2, and the end of the inclined beam 1 is tightly wrapped by the two side plates 22 of the U-shaped connecting head 2, greatly improving the stability and reliability of the connection. Specifically, as shown in the figure, Figure 4 As shown, the connecting head 2 is enclosed by a bottom plate 21 and two side plates 22, forming a stable U-shaped structure. The bottom plate 21 and the side plates 22 are both provided with mounting holes corresponding to the groove 12 on the inclined beam 1, and each mounting hole corresponds to a group of fasteners.

[0039] The number of mounting holes on each side plate 22 of the connecting head 2 is designed flexibly, at least one, to meet different connection requirements. In this embodiment, in order to further improve the stability and flexibility of the connection, two runway-type mounting holes 6 are evenly distributed on each side plate 22 of the connecting head 2. The design of the runway-type mounting hole 6 not only increases the contact area with the T-shaped bolt 4, improves the reliability and durability of the connection, but also allows for a certain degree of fine tuning during installation, ensuring the precise alignment and close fit between the inclined beam 1 and the connecting head 2.

[0040] The two connecting heads 2 are connected by connecting ears 23. Specifically, the inner end of the side plate 22 of the connecting head 2 extends inward to form a connecting ear 23, and the connecting ear 23 is provided with a circular mounting hole 7 matched with the fastener. The connecting ears 23 of the two connecting heads 2 are connected through the cooperation of the fastener and the circular mounting hole 7. The fastener is preferably a bolt and a nut.

[0041] As a further improvement in structure, the groove 12 of the inclined beam 1 is connected to the main body 11 in a U-shaped structure 13. Specifically, as shown in the figure, Figures 5 to 7 The U-shaped structure 13 includes a horizontal plate 131 and two vertical plates, a first vertical plate 132 and a second vertical plate 133 located at the two ends of the horizontal plate 131 and extending parallel from the two ends of the horizontal plate 131 in the same direction. During processing, these components are integrally formed with the main body 11. Compared with the traditional sharp bending angle, this U-shaped transition structure can effectively disperse stress and greatly reduce stress concentration, so that the stress distribution at the connection is more uniform and reasonable. This design not only significantly improves the fatigue resistance of the profile during use and enhances the structural stability, but also greatly improves the overall load capacity and reliability of the photovoltaic support profile, providing protection for the safe and efficient operation of the photovoltaic support.

[0042] The assembly mode of the inclined beam ridge connecting structure is as follows:

[0043] Reference Figure 3 and Figure 4 , first preset T-shaped bolts 4 on each mounting hole of the connecting head 2 through the nut 5, the nut 5 is not locked; then the connecting head with T-shaped bolt 4 is sleeved on the inclined beam 1, the head of T-shaped bolt 4 is slid into the lateral slot of the groove 12, then a certain angle is rotated, the head is clamped in the groove 12 pit, then the nut 5 is tightened. The same way is used to connect the connecting head 2 and the inclined beam 1 on the other side.

[0044] Finally, the connecting ears 23 of the connecting heads 2 on both sides are aligned, and the round mounting holes 7 are locked by bolts and nuts, that is, the whole assembly operation is completed.

[0045] To further illustrate the embodiments, the utility model provides drawings. These drawings are part of the utility model disclosure, which is mainly used to illustrate the embodiments, and can be combined with the related description of the specification to explain the operation principle of the embodiments.
