Solar panel assembly mode: Referring to the sixth figure, the solar panel 91 is slid into between the two opposite groove portions 21, that is, the assembly of the solar panel 91 is completed.

The invention has the following adjustment modes:

[a] lower adjustment mode: Referring to the sixth figure, assuming that the two erecting devices have a first distance L1 between them, and the erecting device on the right side of the sixth figure is located at a first position P1, when cooperating with another location When the design needs to adjust the position, the pair of the lateral segment member 422 and the glide path portion 12 can be loosened by the second lower fixing component 424, and the lower support portion 40 can be used to move the wave plate fixing structure 50 synchronously. Sliding relative to the glide path portion 12 to the second position P2 (converting from the first distance L1 to a second distance L2 as shown in FIG. 7), so that the wave plate fixing structure 50 is fixed to the other protrusion portion as needed The second lower fixing component 424 is used to lock and fix the pair of lateral segments 422 and the glide path portion 12 to complete the lower adjustment mode.

[b] Upper adjustment mode: assuming that the top seat 20 on the left side of the eighth figure is located at a third position P3, the adjacent two groove portions 21 are available for the original solar panel 91 (having a first solar panel width LA) to slide. In the setting, and when the conversion uses another wider solar panel 91A, if the wider solar panel 91A has a second solar panel width LB (greater than the first solar panel width LA), the upper fixing component 324 is permeable. Relaxing the top seat 20 (releasingly with the upper fixing structure 30) and the lateral rail 10, and the top seat 20 and the upper slide portion 11 are relatively slid to a fourth position P4 (the two facing each other) The slot portions 21 are spaced apart from the second solar panel width LB), and the top mount 20 and the lateral rail 10 are locked and fixed by the upper fixing assembly 324 to complete the lower adjustment mode, and the wider solar panel 91A can slide in. The gap between the adjacent two groove portions 21 is provided.

The advantages and functions of the present invention are as follows:

[1] The lower part can be adjusted with different roofing waves. Since the protrusions of the roof wave board have different patterns and intervals, the present invention can relax the second lower fixing component and control the lower support portion to be relatively slippery with respect to the lateral rail in the case where the transverse rail is constant. Alternatively, the wave board fixing structure can be rotated 180 degrees relative to the roof wave board to change the fixing direction of the lower supporting portion and the connecting device, and can be used for different spaced protrusions. Therefore, the lower part can be adjusted with different roof waves.

[2] The upper part can be adjusted according to the solar panels of different widths. Since the solar panel can be adjusted to use different sizes according to different building areas to achieve the shortest assembly man-hour, the present invention is directed to this portion, and the invention can relax the upper fixing component without changing the transverse rail, so that The top seat and the lateral rail slide relative to each other, thereby adjusting the distance between the opposite groove portions, and can be directly applied to the solar panel sliding arrangement of different widths. Therefore, the upper part can be adjusted according to the solar panels of different widths.

[3] The unique upper snap fit design is extremely strong. The top seat of the present invention is topped up by the upper support portion, and is buckled into the pair of clamping portions by the pair of upper clip segments, and is pulled up from the top, that is, the middle is topped up, two The side is pulled down. Of course it is quite solid and fixed. Therefore, the unique upper snap fit design is extremely strong.

[4] The linear groove fixing effect is good. The invention adopts the groove portions facing each other for the solar panels to slide in, that is, the two sides (two straight lines) of the solar panels are completely restricted by the corresponding (linear) groove portions, not just the "points" of the conventional fixing members. Shape" positioning. Therefore, the linear groove portion has a good fixing effect.

[5] The linear groove does not lock the solar panel. The height of the groove portion of the present invention is calculated, and only the solar panel can be slid into the setting, but cannot be detached, and since the solar panel is "restricted" rather than "locked", the linear groove portion is not Lock the solar panels.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
