[0029] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments.

[0030] Example one:

[0031] As Figures 1 to 6 shown, in the embodiment one of the utility model, the utility model discloses a kind of cooperation structure of connecting block and photovoltaic track, it includes photovoltaic track 1 and connecting block 2;Wherein, the upper end of the photovoltaic track 1 is bent inward to form turnup 11 on both sides;The upper side of the connecting block 2 forms two limiting slots 21, and the middle part of connecting block 2 forms screw hole 22 between two limiting slots 21, and connecting block 2 has two clamping parts 24 arranged diagonally;When connecting block 2 and photovoltaic track 1 are fixedly cooperated, connecting block 2 is placed in photovoltaic track 1, and two turnups 11 of photovoltaic track 1 are inserted into two limiting slots 21 of connecting block 2 respectively, at this time, through the limiting cooperation of limiting slot 21 and turnup 11, it is guaranteed that connecting block 2 cannot rotate relative to photovoltaic track 1 and simultaneously connecting block 2 also has the effect of tensioning two turnups 11 of photovoltaic track 1, so as to guarantee that connecting block 2 can be stably cooperated with photovoltaic track 1.

[0032] Specifically, in the embodiment one of the utility model, connecting block 2 is realized fixed cooperation with photovoltaic track 1 by bolt 3 and photovoltaic component 4, and specific cooperation mode is as follows:

[0033] First, bolt 3 is screwed with connecting block 2 after passing through photovoltaic component 4;

[0034] Then, connecting block 2 is inserted into photovoltaic track 1, and photovoltaic component 4 abuts against photovoltaic track 1;

[0035] Then, the bolt 3 is rotated in the locking direction, so that the clamping portion 24 of the connecting block 2 first abuts against the inner side wall of the photovoltaic track 1, and the rotation of the bolt 3 drives the connecting block 2 to move upward; after the connecting block 2 moves a certain distance, the two flanges 11 of the photovoltaic track 1 are respectively inserted into the two limiting grooves 21 of the connecting block 2; thereafter, continuing to rotate the bolt 3 makes the two flanges 11 of the photovoltaic track 1 respectively fully inserted into the two limiting grooves 21 of the connecting block 2, so that the connecting block 2 and the bolt 3 tightly hold the photovoltaic track 1 and the photovoltaic component 4.

[0036] In the embodiment one of the utility model, cooperate Figure 4 As shown in the figure, the width of the connecting block 2 is tapered from bottom to top, which can reduce the material of the connecting block 2 while ensuring the strength of the limiting groove 21, and play a role in reducing cost. The connecting block 2 can be metal material, so that the connecting block 2 has the advantage of high strength.

[0037] In the embodiment one of the utility model, the connecting block 2 has two diagonal arranged avoiding portions 23, the maximum distance of the two avoiding portions 23 is less than the maximum width of the inner side of the photovoltaic track 1, and the maximum distance from the avoiding portion 23 to the center of the screw hole 22 is less than the maximum distance from the clamping portion 24 to the center of the screw hole 22; in this way, when the connecting block 2 is inserted into the photovoltaic track 1, the connecting block 2 can be directly inserted from the upper opening of the photovoltaic track 1, and then the connecting block 2 is rotated to the clamping portion 24 of the connecting block 2 abutting against the inner wall of the photovoltaic track 1, thereafter, the bolt 3 can be rotated in the locking direction to drive the connecting block 2 to move upward.
