[0035] A purlin installation structure includes purlins 3 and clamping assemblies 4. The four corners of the purlins 3 are fixed to two adjacent frames 1 surrounding a solar panel by fasteners. The clamping assembly 4 includes two arc-shaped clips 42.

[0036] The purlin 3 is provided with a downwardly recessed mounting groove 31; the bottom of the mounting groove 31 is provided with two first through holes 311, and the two first through holes 311 are arranged at intervals along the length of the mounting groove 31; the two sides of the mounting groove 31 are respectively provided with two second through holes 313; the first through holes 311 are located between the two opposite second through holes 313.

[0037] The upper end of the arc-shaped clip 42 is provided with a T-shaped buckle 421, and the lower end of the arc-shaped clip 42 is provided with a fastener mounting hole; the top of the T-shaped buckle 421 is provided with two side ends 4211; the two side ends 4211 are respectively mounted on two opposite second through holes 313, and the lower end of the T-shaped buckle 421 connected to the middle part of the arc-shaped clip 42 is located in the first through hole 311;

[0038] The bottom of the mounting groove 31 and the concave surfaces of the two arc-shaped clips 42 abut against the outer circumference of the main beam 2, and the lower ends of the two arc-shaped clips 42 are connected by fasteners.

[0039] Figure 1 This is a schematic diagram of the installation structure of one embodiment of the purlin installation structure of this utility model. Figure 2 This is a schematic diagram of the installation structure of the clamp 5 of this utility model. Figure 3 This is a bottom view of the purlin 3 of this utility model.

[0040] like Figure 1-3 As shown, before installation, the top surfaces of the two side walls of the mounting groove 31 are pressed against the bottom surfaces of the two adjacent frames 1 surrounding the solar panel. Then, the first fastener is passed through the corresponding fastener mounting holes 30 on the purlin 3 to fix the purlin 3 to the bottom surfaces of the two adjacent frames 1, forming a solar panel assembly. During installation, the solar panel assembly is placed on the top surface of the main beam 2. Then, the upper ends of the two arc-shaped clips 42 are passed through the corresponding first through holes 311 and rotated 90° so that the extension direction of the top of the T-shaped buckle 421 is perpendicular to the length direction of the purlin 3, so that the two side ends 4211 of the top of the T-shaped buckle 421 are inserted into the two corresponding second through holes 313. Finally, the lower ends of the two arc-shaped clips 42 are fixed with the second fastener, thus completing the installation of fixing a solar panel assembly to the main beam 2.

[0041] Furthermore, the clamp assembly 4 also includes a connecting seat 41;

[0042] The connecting seat 41 is provided with an upwardly recessed hollow groove 411;

[0043] The bottom of the hollow groove 411 has two third through holes 4111, and the two third through holes 4111 are arranged at intervals along the length of the hollow groove 411.

[0044] The top surface of the connecting seat 41 is used to support the bottom surface of the purlin 3; the bottom surface of the connecting seat 41 abuts against the outer circumferential surface of the main beam 2;

[0045] The first through hole 311 and the third through hole 4111 are one-to-one corresponding. The lower end of the T-shaped buckle 421 passes through the third through hole 4111 and extends into the corresponding first through hole 311.

[0046] like Figure 2 and Figure 3 As shown, during installation, first insert the upper ends of the two arc-shaped clips 42 into the two third through holes 4111 on the connector 41, then let the upper ends of the arc-shaped clips 42 pass through the corresponding first through holes 311, and then rotate the arc-shaped clips 42 by 90° so that the two side ends 4211 of the top of the T-shaped buckle 421 are engaged in the two corresponding second through holes 313.

[0047] like Figure 1-4 As shown, a connecting seat 41 is provided between the purlin 3 and the main beam 2. The connecting seat 41 supports the bottom surface of the purlin 3, which can improve the installation stability of the purlin 3 and the clamp assembly 4 on the main beam 2. The connecting seat 41, two arc-shaped clamps 42 and the second fastener can also be pre-assembled into the clamp assembly 4 and fitted onto the outer circumference of the main beam 2. This can improve the ease of access to the clamp assembly 4, reduce the workload of finding the clamp assembly 4, and thus improve the efficiency of the rapid installation of the purlin 3.

[0048] Furthermore, the side end 4211 is provided with a lower hook 42111;

[0049] The lower hook 42111 protrudes downward from the bottom edge of the side end 4211, and the lower hook 42111 is exposed downward below the bottom edge of the second through hole 313.

[0050] like Figure 1 , Figure 2 and Figure 6 As shown, a lower hook 42111 is provided at the bottom of the side end 4211 of the T-shaped buckle 421, and the rotation of the T-shaped buckle 421 in the second through hole 313 is restricted by the lower hook 42111, which can prevent the arc-shaped clip 42 from moving due to wind force during use and causing the T-shaped buckle 421 to loosen.

[0051] Furthermore, the connecting seat 41 is also provided with an upright card insert 412; the bottom of the mounting groove 31 is also provided with a fifth through hole 312;

[0052] The fifth through hole 312 is located between the two first through holes 311;

[0053] The card insert 412 protrudes upward from the top surface of the connector 41, and the upper card 412 is located between the two third through holes 4111; the top of the card insert 412 extends laterally and is perpendicular to the length direction of the connector 41.

[0054] The insert 412 is used to insert into the fifth through hole 312 and restricts the relative movement between the connector 41 and the purlin 3.

[0055] like Figure 3 and Figure 4 As shown, during installation, the fifth through hole 312 is inserted through the clip 412, and the movement of the connecting seat 41 relative to the purlin 3 is restricted, which can further improve the installation stability of the purlin 3 and the clamp assembly 4 on the main beam 2.

[0056] Furthermore, the fifth through hole 312 is provided with two inner protrusions 3121;

[0057] The two inner protrusions 3121 protrude inward from the two sides of the fifth through hole 312 along the length direction perpendicular to the fifth through hole 312 and are arranged opposite to each other, with the two inner protrusions 3121 close to one end of the fifth through hole 312;

[0058] The insert 412 is housed between the two inner protrusions 3121 and one end of the fifth through hole 312.

[0059] like Figure 4 and Figure 5 As shown, during installation, the card insert 412 is placed between the two inner protrusions 3121 and one end of the fifth through hole 312. This prevents the card insert 412 from moving to the other end of the fifth through hole 312 under external force, further improving the installation stability of the connecting seat 41 and the purlin 3.

[0060] In summary, such as Figure 1-6 The embodiment of the present invention shown in the figure has a purlin installation structure in which the purlin 3 and the clamp assembly 4 are connected by a snap-fit ​​connection. The installation structure is simple and can improve the convenience and efficiency of purlin installation.

[0061] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
