[0002] At present, photovoltaic panels are fixed to the crossbeams of photovoltaic brackets through snap-on assemblies, specifically, the side and middle snap blocks are snapped onto the buckle grooves of the crossbeams of the photovoltaic brackets through bolts and sheet nuts. The bolts, sheet nuts and snap blocks in the traditional snap-on assemblies are separate independent parts, wherein the bolts are full-thread bolts, and the sheet nuts are preferably plastic wing nuts, which are very convenient for clamping onto the buckle grooves of the crossbeams. Specifically, during installation, it is necessary to first place the plastic wing nut into the buckle groove and rotate it 90° to get it stuck in the buckle groove, then move it to the approximate position, then place the snap block in the screw hole position of the nut, screw the bolt through the mounting hole of the snap block into the nut, then move the entire snap-on assembly to the appropriate position, and finally tighten the bolt. Therefore, the traditional snap-on assemblies have the following defects:

[0003] 1. Each component is a separate structure, which not only causes the problem of components falling off during installation, but also causes the problem of complicated installation operation;

[0004] 2. Since the plastic wing nut is installed first during installation, it is necessary to align the screw hole of the pressure block with the nut and then install the bolt. After installation, the position is adjusted. During the process of adjusting the position, the pressure block needs to be kept lifted up so that the pressure block can be located above the photovoltaic panel, which makes the installation operation troublesome.

[0005] Based on this, the present application provides an integrated snap-in assembly for photovoltaic panel installation that is easy to install to solve the above-mentioned problems. Utility Model Content

[0031] Embodiment 1

[0032] This embodiment provides an integrated buckle assembly for installing a photovoltaic panel, as shown in the attached Figure 1 As shown, it includes a sheet nut 1, a bolt 2 and a pressing block 3, wherein the pressing block can be as shown in the attached Figure 6 The side pressure block shown in the figure can also be as shown in the attached figure. Figure 1 or attached Figure 5 The medium pressure block shown.

[0033] As attached Figure 1 and attached Figure 2 As shown, both ends of the sheet nut 1 are provided with bending sections 1.1 for buckling with the buckle groove of the cross beam 10 of the photovoltaic support. The bottom surface of the sheet nut 1 is also fixedly connected with a spring 4 for tightening the sheet nut against the buckle groove. This design enables the sheet nut to self-maintain its position and limit its twisting after being buckled with the buckle groove. Preferably, the width of the sheet nut 1 is smaller than the inner width of the buckle groove, and its length is smaller than the inner width of the cross beam. This design facilitates the sheet nut to enter the cross beam from the buckle groove. Specifically, after placing the sheet nut into the buckle groove, press down the nut and rotate it 90° to complete the buckle connection between the sheet nut and the buckle groove.

[0034] Preferably, as attached Figure 2 As shown, a positioning protrusion 1.2 is provided in the middle of the bottom surface of the sheet nut 1, and a screw hole thereof penetrates the positioning protrusion, and the spring 4 is fixedly sleeved on the positioning protrusion 1.2. This design can increase the contact area between the spring and the sheet nut, so that the fixed connection effect of the spring is better, and the fixed connection method can be welding, or a ring can be inserted into the spring and then fixed by screws (not shown in the figure).

[0035] As attached Figure 1 and attached Figure 2 As shown, the bolt 2 is a half-thread bolt, and its smooth rod portion is provided with a retaining ring groove 2.1. The pressing block 3 is provided on the smooth rod portion of the bolt 2 and is limited by a retaining ring 5 inserted into the retaining ring groove 2.1. The threaded portion of the bolt 2 is screwed to the sheet nut 1. This design allows the pressing block to always remain at the head position of the screw rod and will not fall. During the installation of the buckling assembly, it is not necessary to lift it up, which simplifies the installation operation and reduces the difficulty of installation. Preferably, the distance between the retaining ring groove 2.1 and the head of the bolt 2 in this embodiment is equal to the thickness of the pressing block 3.

[0036] Preferably, a rubber pad 6 is provided on the surface of the pressing block 3 that contacts the frame of the photovoltaic panel, and the rubber pad can effectively prevent the pressing block from pressurizing the photovoltaic panel and causing damage to the photovoltaic panel.

[0037] In the specific implementation, the installation of the middle pressure block is taken as an example: put the sheet nut of the integrated buckle assembly into the buckle groove of the crossbeam, and the state is as shown in the attached figure. Figure 3 As shown, then press the pressing block down to make the sheet nut completely enter the beam, then use your fingers to swing the sheet nut to twist it 90°, and then release the pressing block. At this time, the buckle assembly is stuck in the buckle groove under the action of the spring, and the pressing block always remains at the head position of the bolt, directly push the buckle assembly to contact with the previous photovoltaic panel, and then push the next photovoltaic panel directly into place. Since the pressing blocks of multiple buckle assemblies can form a plane, the next photovoltaic panel can be directly pushed to the junction with the pressing block, and finally tighten it to complete the installation. The final installation effect is shown in the attached figure. Figure 4 and attached Figure 5 shown.

[0038] Similarly, the installation method for the side clamp is similar. After the sheet nut is buckled with the buckle groove, move it to the set position, push the photovoltaic panel until it contacts the clamp, and finally tighten the bolts. The final installation effect is as shown in the attached figure. Figure 6 shown.

[0039] The integrated buckle assembly designed in this embodiment will not have the problem of small parts falling off during installation. At the same time, there is no need to lift the pressure block all the time during installation. You only need to insert the sheet nut into the buckle groove and directly push the buckle assembly to the installation position, which greatly simplifies the installation operation steps and improves the convenience of installation.

[0040] Embodiment 2

[0041] Based on the first embodiment, as shown in the attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, in this embodiment, a pull rope 7 is further provided on the side of the sheet nut 1, which is used to pull the sheet nut to rotate after it is placed in the buckle groove. Specifically, the pull rope can be arranged at one end of the sheet nut by tying, or can be fixed to one side of one end of the sheet nut by screws.

[0042] During the specific implementation, before placing the sheet nut into the buckle groove, place the pull rope outside the beam. After the sheet nut is pressed into the beam, pull the pull rope to rotate the sheet nut 90°. This method of using the pull rope to pull the sheet nut solves the inconvenience of having to enter the beam by hand to twist the nut (the buckle groove space is small and the operation is difficult), further improving the convenience of installation.

[0043] Embodiment 3

[0044] Based on the first or second embodiment, as shown in the attached Figure 2 As shown, in this embodiment, a limit retaining ring 8 is installed on the bottom surface of the rod of the bolt 2 through a screw to prevent the sheet nut from being screwed out and falling off due to accidental screwing.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
