[0002] With the development of technology, photovoltaic (PV) modules are being used more and more widely.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0022] like Figures 1 to 21 As shown, the photovoltaic profiled plate support 100 includes: a base 10, a first opening and closing piece 40, and a second opening and closing piece 50.

[0023] The base 10 is used to be installed on the roof. The first opening and closing piece 40 and the second opening and closing piece 50 are rotatably connected to the base 10 respectively. The first opening and closing piece 40 and the second opening and closing piece 50 are used to change their positions during the installation of the photovoltaic profiled plate 200 so that the photovoltaic profiled plate 200 is installed on the photovoltaic profiled plate support 100.

[0024] In this embodiment, by setting the first opening and closing piece 40 and the second opening and closing piece 50 to be rotatably connected to the base 10, the positions of the first opening and closing piece 40 and the second opening and closing piece 50 can change when installing the photovoltaic profiled plate 200, avoiding hard contact with the concealed ribs of the photovoltaic profiled plate 200. That is, the concealed ribs of the photovoltaic profiled plate 200 are not subjected to hard extrusion deformation, and the photovoltaic profiled plate 200 is not subjected to hard extrusion deformation. This avoids the problem of damage to the photovoltaic profiled plate 200 and the photovoltaic profiled plate support 100 due to hard extrusion deformation during the installation of the photovoltaic profiled plate 200 on the photovoltaic profiled plate support 100.

[0025] In addition, in this embodiment, the first opening and closing piece 40 switches between a first position and a second position, and the second opening and closing piece 50 switches between a third position and a fourth position, with the first opening and closing piece 40 and the second opening and closing piece 50 positioned opposite each other. In the case of the photovoltaic profiled plate 200, the concealed ribs of the photovoltaic profiled plate 200 press against the first opening and closing piece 40 and the second opening and closing piece 50. The first opening and closing piece 40 switches from the first position to the second position, and the second opening and closing piece 50 switches from the third position to the fourth position. When the photovoltaic profiled plate 200 is installed, the first opening and closing piece 40 switches from the second position to the first position, and the second opening and closing piece 50 switches from the fourth position to the third position to block the concealed ribs of the photovoltaic profiled plate and prevent the photovoltaic profiled plate 200 from separating from the photovoltaic profiled plate support 100.

[0026] In this embodiment, since the first opening and closing piece 40 and the second opening and closing piece 50 are rotatably connected to the base 10 and are positioned opposite each other, the first opening and closing piece 40 can rotate relative to the base 10, allowing it to switch between a first position and a second position. The second opening and closing piece 50 can rotate relative to the base 10, allowing it to switch between a third position and a fourth position. Thus, when the photovoltaic profiled plate 200 is installed, the concealed ribs of the photovoltaic profiled plate 200 press the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 to rotate relative to the base 10, and the second opening and closing piece 50 to rotate relative to the base 10. The first opening and closing piece 40 switches from the first position to the second position, and the second opening and closing piece 50 switches from the third position to the fourth position, so that the first opening and closing piece 40 and the second opening and closing piece 50 obstruct the concealed ribs less, allowing the concealed ribs to be installed quickly. After the photovoltaic profiled sheet 200 is installed, the first opening and closing piece 40 switches from the second position to the first position, and the second opening and closing piece 50 switches from the fourth position to the third position. Thus, the first opening and closing piece 40 and the second opening and closing piece 50 block the ribs and prevent the photovoltaic profiled sheet 200 from separating from the photovoltaic profiled sheet support 100. That is, in this embodiment of the application, by setting the first opening and closing piece 40 and the second opening and closing piece 50 to be rotatably connected to the base 10 respectively, and the first opening and closing piece 40 and the second opening and closing piece 50 being in opposite positions, the first opening and closing piece 40 and the second opening and closing piece 50 can change positions when installing the photovoltaic profiled plate 200, avoiding hard contact with the concealed ribs of the photovoltaic profiled plate 200. That is, the concealed ribs of the photovoltaic profiled plate 200 are not subjected to hard extrusion deformation, and the photovoltaic profiled plate 200 is not subjected to hard extrusion deformation. This avoids the problem of damage to the photovoltaic profiled plate 200 and the photovoltaic profiled plate support 100 due to hard extrusion deformation during the installation of the photovoltaic profiled plate 200 on the photovoltaic profiled plate support 100.

[0027] It should be noted that the first position and the third position are two opposite positions, and the second position and the fourth position are two opposite positions. Furthermore, when the first opening / closing piece 40 switches from the first position to the second position, simultaneously, the second opening / closing piece 50 switches from the third position to the fourth position.

[0028] In some embodiments, the base 10 is provided with a rotating hole 101, the rotating member 20 passes through the rotating hole 101, the torsion spring 30 is sleeved on the rotating member 20, and the base 10 is used to be installed on the roof; the first opening and closing piece 40 is provided with a first rotating hole 41, and the second opening and closing piece 50 is provided with a second rotating hole 51. The first opening and closing piece 40 is sleeved on the rotating member 20 through the first rotating hole 41, and the second opening and closing piece 50 is sleeved on the rotating member 20 through the second rotating hole 51, and the first opening and closing piece 40 and the second opening and closing piece 50 are positioned opposite each other. One end of the torsion spring 30 is located on the side of the first opening and closing piece 40 facing the base 10 and is in contact with the first opening and closing piece 40. The other end of the torsion spring 30 is located on the side of the second opening and closing piece 50 facing the base 10 and is in contact with the second opening and closing piece 50. The two ends of the torsion spring 30 support the first opening and closing piece 40 and the second opening and closing piece 50 respectively. The torsion spring 30 is used to drive the first opening and closing piece to switch between the first position and the second position, and to drive the second opening and closing piece to switch between the third position and the fourth position.

[0029] Since the base 10 is provided with a rotating hole 101, the rotating member 20 passes through the rotating hole 101, the first opening and closing piece 40 is sleeved on the rotating member 20 through the first rotating hole 41, and the second opening and closing piece 50 is sleeved on the rotating member 20 through the second rotating hole 51. Therefore, when the first opening and closing piece 40 and the second opening and closing piece 50 are subjected to force, both the first opening and closing piece 40 and the second opening and closing piece 50 can rotate relative to the rotating member 20. Since the torsion spring 30 is sleeved on the rotating member 20, and one end of the torsion spring 30 is in contact with the first opening and closing piece 40 and the other end of the torsion spring 30 is in contact with the second opening and closing piece 50, when the first opening and closing piece 40 and the second opening and closing piece 50 are rotated under force, the first opening and closing piece 40 and the second opening and closing piece 50 respectively exert force on both ends of the torsion spring 30, so that the two ends of the torsion spring 30 are compressed under force, causing the first opening and closing piece 40 and the second opening and closing piece 50 to rotate relative to the rotating member 20. After the first opening and closing piece 40 and the second opening and closing piece 50 stop being subjected to force, the two ends of the torsion spring 30 respectively drive the first opening and closing piece 40 and the second opening and closing piece 50 to return to their original positions.

[0030] Therefore, when using the photovoltaic profiled sheet support 100 provided in this application embodiment, after the base 10 of the photovoltaic profiled sheet support 100 is installed on the roof, when installing the photovoltaic profiled sheet 200, the concealed fastener of the photovoltaic profiled sheet 200 will be installed on the photovoltaic profiled sheet support 100. During the installation process, the concealed fastener rib of the photovoltaic profiled sheet 200 will first contact the first opening and closing piece 40 and the second opening and closing piece 50, so that the rib will exert force on the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 and the second opening and closing piece 50 to rotate relative to the rotating member 20, that is, the first opening and closing piece 40 and the second opening and closing piece 50 are equivalent to retracting, and the first opening and closing piece 40 moves from the first position. Switching to the second position, the second opening and closing piece 50 switches from the third position to the fourth position. After the first opening and closing piece 40 and the second opening and closing piece 50 are in the concealed fastener of the photovoltaic profiled plate 200, the first opening and closing piece 40 and the second opening and closing piece 50 stop being subjected to the force of the concealed fastener rib. The torsion spring 30 will then drive the first opening and closing piece 40 and the second opening and closing piece 50 to reset. That is, the first opening and closing piece 40 switches from the second position to the first position, and the second opening and closing piece 50 switches from the fourth position to the third position, so that the first opening and closing piece 40 and the second opening and closing piece 50 can block the concealed fastener rib and prevent the photovoltaic profiled plate 200 from separating from the photovoltaic profiled plate support 100, thereby completing the installation of the photovoltaic profiled plate 200.

[0031] That is, in this embodiment, the torsion spring 30, the first opening and closing piece 40, and the second opening and closing piece 50 are all passed through the rotating member 20, and one end of the torsion spring 30 contacts the first opening and closing piece 40, and the other end of the torsion spring 30 contacts the second opening and closing piece 50. So when the photovoltaic profiled plate 200 is installed on the photovoltaic profiled plate support 100, the first opening and closing piece 40 and the second opening and closing piece 50 will not make hard contact with the concealed ribs of the photovoltaic profiled plate 200 due to the action of the torsion spring 30. That is, the concealed ribs of the photovoltaic profiled plate 200 are not subjected to hard extrusion deformation, and the photovoltaic profiled plate support 100 is not subjected to hard extrusion deformation. This can avoid the problem of damage to the photovoltaic profiled plate 200 and the photovoltaic profiled plate support 100 due to hard extrusion deformation during the installation of the photovoltaic profiled plate 200 on the photovoltaic profiled plate support 100.

[0032] For example, refer to Figure 5 The diagram illustrates the process of installing the photovoltaic profiled sheet 200. Figure 5 As shown in Figure (a), during the installation of the photovoltaic profiled sheet 200, the photovoltaic profiled sheet 200 is pressed down. The concealed ribs of the photovoltaic profiled sheet 200 first come into contact with the first opening and closing piece 40 and the second opening and closing piece 50, and squeeze the first opening and closing piece 40 and the second opening and closing piece 50, that is, force is applied to the first opening and closing piece 40 and the second opening and closing piece 50. Figure 5 As shown in Figure (b), the first opening / closing piece 40 and the second opening / closing piece 50 will retract. Figure 5As shown in Figure (c), after the first opening / closing piece 40 and the second opening / closing piece 50 are in the concealed fastener, the concealed fastener ribs no longer press against the first opening / closing piece 40 and the second opening / closing piece 50, that is, the concealed fastener ribs no longer contact the first opening / closing piece 40 and the second opening / closing piece 50. The first opening / closing piece 40 and the second opening / closing piece 50 will be subjected to the force of the torsion spring 30, thereby the first opening / closing piece 40 and the second opening / closing piece 50 begin to reset. Figure 5 As shown in Figure (d), the first opening / closing piece 40 and the second opening / closing piece 50 are reset due to the force of the torsion spring 30. That is, during the installation of the photovoltaic profiled sheet 200, the contact between the photovoltaic profiled sheet 200 and the photovoltaic profiled sheet support 100 is not a hard contact; that is, the first opening / closing piece 40 and the second opening / closing piece 50 will retract and will also unfold under the action of the torsion spring 30. This avoids hard compression between the photovoltaic profiled sheet 200 and the photovoltaic profiled sheet support 100 during the installation of the photovoltaic profiled sheet 200, thus preventing damage to both the photovoltaic profiled sheet 200 and the photovoltaic profiled sheet support 100.

[0033] It should be noted that, in the embodiments of this application, the middle part of the photovoltaic profiled sheet 200 is usually designed with one or more mushroom-shaped protrusions. The corners on both sides of the mushroom-shaped protrusions face downwards at less than 90°, so that the protrusion structure forms the hidden fastener of the photovoltaic profiled sheet 200, and the corners on both sides are the ribs.

[0034] In some embodiments, the first hinged piece 40 may have a first flange 42 at one end near the second hinged piece 50, and the first flange 42 and the first hinged piece 40 form a first angle. The second hinged piece 50 may have a second flange 52 at one end near the first hinged piece 40, and the second flange 52 and the second hinged piece 50 form a second angle, with the second flange 52 and the first flange 42 positioned opposite each other. When the first hinged piece 40 and the second hinged piece 50 move in a direction away from the base 10, the first flange 42 and the second flange 52 abut against each other to prevent the first hinged piece 40 and the second hinged piece 50 from moving.

[0035] Since the first flap 40 is provided with a first flange 42 at the end near the second flap 50, and the second flap 50 is provided with a second flange 52 at the end near the first flap 40, and the first flange 42 and the second flange 52 are positioned opposite each other, when the first flap 40 and the second flap 50 are rotated in opposite directions, that is, when the first flap 40 and the second flap 50 rotate in the direction away from the base 10, the first flange 42 and the second flange 52 will abut against each other, thereby the first flange 42 and the second flange 52 exert force on each other, preventing the first flap 40 from driving the first flange 42 to rotate, and the second flap 50 from driving the second flange 52 to rotate. During the installation of the photovoltaic profiled sheet 200, the concealed ribs of the photovoltaic profiled sheet 200 cause the first opening and closing piece 40 and the second opening and closing piece 50 to rotate. At this time, the first opening and closing piece 40 rotates in the forward direction, and the second opening and closing piece 50 rotates in the forward direction. The reverse rotation direction of the first opening and closing piece 40 is opposite to the forward rotation direction, and the reverse rotation direction of the second opening and closing piece 50 is opposite to the forward rotation direction. That is, when the first opening and closing piece 40 rotates toward the base 10, the first opening and closing piece 40 rotates in the forward direction; when the second opening and closing piece 50 rotates toward the base 10, the second opening and closing piece 50 rotates in the forward direction; when the first opening and closing piece 40 rotates away from the base 10, the first opening and closing piece 40 rotates in the reverse direction; when the second opening and closing piece 50 rotates away from the base 10, the second opening and closing piece 50 rotates in the reverse direction.

[0036] In addition, during the installation of the photovoltaic profiled sheet 200 on the photovoltaic profiled sheet support 100, the ribs of the photovoltaic profiled sheet 200 press against the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 and the second opening and closing piece 50 to rotate in the forward direction. After the photovoltaic profiled sheet 200 is installed, if the photovoltaic profiled sheet 200 is subjected to wind force, the ribs of the photovoltaic profiled sheet 200 will re-contact with the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 and the second opening and closing piece 50 to rotate in the reverse direction. However, after the first opening and closing piece 40 and the second opening and closing piece 50 rotate in the reverse direction, the first flange 42 and the second flange 52 will abut against each other, thereby preventing the first opening and closing piece 40 and the second opening and closing piece 50 from continuing to rotate in the reverse direction, thus preventing the photovoltaic profiled sheet 200 from separating from the photovoltaic profiled sheet support 100 due to wind force. That is, by setting the first flange 42 and the second flange 52, the photovoltaic profiled sheet 200 can be improved in terms of wind resistance after it is installed on the photovoltaic profiled sheet support 100.

[0037] In addition, in some embodiments, a first supporting flange 43 is provided on the first flange 42, and a first set angle is formed between the first supporting flange 43 and the first flange 42. A second supporting flange 53 is provided on the second flange 52, and a second set angle is formed between the second supporting flange 53 and the second flange 52. The first supporting flange 43 and the second supporting flange 53 are used to support the photovoltaic profiled plate 200.

[0038] Because the first flange 42 is provided with a first supporting flange 43 and the second flange 52 is provided with a second supporting flange 53, after the photovoltaic profiled sheet 200 is installed on the photovoltaic profiled sheet support 100, if the photovoltaic profiled sheet 200 is stepped on, that is, if the concealed rib of the photovoltaic profiled sheet 200 is stepped on, the first supporting flange 43 and the second supporting flange 53 can support the concealed rib of the photovoltaic profiled sheet 200, thus preventing the photovoltaic profiled sheet 200 from being damaged by stepping. In other words, by providing the first supporting flange 43 on the first flange 42 and the second supporting flange 53 on the second flange 52, the anti-stepping ability of the photovoltaic profiled sheet 200 can be improved, preventing the photovoltaic profiled sheet 200 from being deformed by the pressure of stepping. Furthermore, the first support flange 43 and the second support flange 53 support the photovoltaic profiled plate 200, which can also prevent the stepping force on the photovoltaic profiled plate 200 from being transmitted to the first flange 42, the first opening and closing piece 40, the second flange 52 and the second opening and closing piece 50, thereby also preventing the photovoltaic profiled plate support 100 from being squeezed and deformed.

[0039] It should be noted that in this embodiment, the first support flange 43 and the second support flange 53 can be positioned opposite each other. Of course, the first support flange 43 and the second support flange 53 can also be offset from each other; this embodiment does not limit this. Furthermore, the first set angle can be set according to actual needs; for example, the first set angle can be 90 degrees, or even 85 degrees. The specific value of the first set angle is not limited in this embodiment. Additionally, the size of the second set angle can be equal to the size of the first set angle.

[0040] Additionally, in some embodiments, such as Figures 18 to 22 As shown, a first blocking flange 44 is provided on the first flange 42, and the first blocking flange 44 and the first flange 42 have a first preset angle between them, and the first blocking flange 44 abuts against the first opening and closing piece. A second blocking flange 54 is provided on the second flange 52, and the second blocking flange 54 and the second flange 52 have a second preset angle between them, and the second blocking flange 54 abuts against the second opening and closing piece.

[0041] Since the first flange 42 is provided with a first blocking flange 44, which abuts against the first opening and closing piece, and the second flange 52 is provided with a second blocking flange 54, which abuts against the second opening and closing piece, when the first opening and closing piece 40 and the second opening and closing piece 50 are rotated in opposite directions, that is, when the first opening and closing piece 40 and the second opening and closing piece 50 rotate in the direction away from the base 10, the first flange 42 and the second flange 52 will abut against each other. Thus, the first flange 42 and the second flange 52 exert force on each other, preventing the first opening and closing piece from driving the first flange 42 to rotate and the second opening and closing piece from driving the second flange 52 to rotate. In addition, the first blocking flange 44 will also exert force on the first opening and closing piece 40, and the second blocking flange 54 will also exert force on the second opening and closing piece 50, further preventing the first opening and closing piece 40 and the second opening and closing piece 50 from rotating. That is, the first flange 42 and the second flange 52 exert force on each other to prevent the first opening and closing piece 40 from driving the first flange 42 to rotate, and the second opening and closing piece 50 from driving the second flange 52 to rotate, so as to prevent the first opening and closing piece 40 and the second opening and closing piece 50 from rotating in opposite directions. Furthermore, the first blocking flange 44 exerts force on the first opening and closing piece 40, and the second blocking flange 54 exerts force on the second opening and closing piece 50, further preventing the first opening and closing piece 40 and the second opening and closing piece 50 from rotating in opposite directions.

[0042] During the installation of the photovoltaic profiled sheet 200, the concealed ribs of the photovoltaic profiled sheet 200 cause the first opening and closing piece 40 and the second opening and closing piece 50 to rotate. At this time, the first opening and closing piece 40 rotates in the forward direction, and the second opening and closing piece 50 rotates in the forward direction. The reverse rotation direction of the first opening and closing piece 40 is opposite to the forward rotation direction, and the reverse rotation direction of the second opening and closing piece 50 is opposite to the forward rotation direction. That is, when the first opening and closing piece 40 rotates toward the base 10, the first opening and closing piece 40 rotates in the forward direction; when the second opening and closing piece 50 rotates toward the base 10, the second opening and closing piece 50 rotates in the forward direction; when the first opening and closing piece 40 rotates away from the base 10, the first opening and closing piece 40 rotates in the reverse direction; when the second opening and closing piece 50 rotates away from the base 10, the second opening and closing piece 50 rotates in the reverse direction.

[0043] Furthermore, during the installation of the photovoltaic profiled sheet 200 on the photovoltaic profiled sheet support 100, the ribs of the photovoltaic profiled sheet 200 press against the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 and the second opening and closing piece 50 to rotate in the forward direction. After the photovoltaic profiled sheet 200 is installed, if the photovoltaic profiled sheet 200 is subjected to wind force, the ribs of the photovoltaic profiled sheet 200 will re-contact the first opening and closing piece 40 and the second opening and closing piece 50, causing the ribs of the photovoltaic profiled sheet 200 to... The first opening and closing piece 40 and the second opening and closing piece 50 rotate in opposite directions. However, after the first opening and closing piece 40 and the second opening and closing piece 50 rotate in opposite directions, the first flange 42 and the second flange 52 will abut against each other, thereby preventing the first opening and closing piece 40 and the second opening and closing piece 50 from continuing to rotate in opposite directions. Furthermore, the first blocking flange 44 applies force to the first opening and closing piece 40, and the second blocking flange 54 applies force to the second opening and closing piece 50, thereby preventing the photovoltaic profiled plate 200 from separating from the photovoltaic profiled plate support 100 due to wind force. That is, by setting the first flange 42 and the second flange 52, setting the first blocking flange 44 on the first flange 42, and setting the second blocking flange 54 on the second flange 52, the wind resistance of the photovoltaic profiled plate 200 can be further improved after it is installed on the photovoltaic profiled plate support 100.

[0044] In addition, in this embodiment, the two ends of the torsion spring 30 can contact the first opening / closing plate 40 and the second opening / closing plate 50 in different ways. The following two examples will be used for illustration: Method (1): The first opening and closing piece 40 may include a first intermediate piece 401, a first side wall 402 and a second side wall 403. The first side wall 402 and the second side wall 403 are both connected to the same surface of the first intermediate piece 401, and the first side wall 402 and the second side wall 403 are spaced apart. The first side wall 402 and the second side wall 403 are both provided with a first rotating hole 41. The first side wall 402 and the second side wall 403 are sleeved on the rotating member 20 through the first rotating hole 41. The first side wall 402 and / or the second side wall 403 are provided with a first mounting hole 4021. One end of the torsion spring 30 is located in the first mounting hole 4021 on the first side wall 402 or the first mounting hole 4021 on the second side wall 403. The second opening / closing piece 50 includes a second intermediate piece 501, a third side wall 502, and a fourth side wall 503. The third side wall 502 and the fourth side wall 503 are both connected to the same surface of the second intermediate piece 501, and the third side wall 502 and the fourth side wall 503 are spaced apart. The third side wall 502 and the fourth side wall 503 are each provided with a first rotating hole 41. The third side wall 502 and the fourth side wall 503 are sleeved on the rotating member 20 through the first rotating hole 41. The third side wall 502 and / or the fourth side wall 503 are provided with a second mounting hole 5021. One end of the torsion spring 30 is located in the second mounting hole 5021 on the third side wall 502 or the second mounting hole 5021 on the fourth side wall 503.

[0045] Since the first sidewall 402 and the second sidewall 403 are both connected to the same surface of the first intermediate piece 401, and the first sidewall 402 and the second sidewall 403 are spaced apart, and the first sidewall 402 and the second sidewall 403 are both provided with first rotating holes 41, when the first opening and closing piece 40 needs to be inserted into the rotating member 20, the first rotating holes 41 on the first sidewall 402 and the second sidewall 403 can be inserted into the rotating member 20, that is, the first sidewall 402 and the second sidewall 403 can be sleeved onto the rotating member 20 through the first rotating holes 41. A first mounting hole 4021 is provided on the first sidewall 402 and / or the second sidewall 403. One end of the torsion spring 30 is located in the first mounting hole 4021 on the first sidewall 402 or the first mounting hole 4021 on the second sidewall 403. Thus, one end of the torsion spring 30 can contact the first sidewall 402 or the second sidewall 403. When the first opening and closing piece 40 is subjected to the force of the concealed rib of the photovoltaic profiled plate 200, the first opening and closing piece 40 can drive one end of the torsion spring 30 to rotate, thereby applying force to one end of the torsion spring 30. That is, the hole wall of the first mounting hole 4021 on the first sidewall 402 or the hole wall of the first mounting hole 4021 on the second sidewall 403 applies force to one end of the torsion spring 30, causing one end of the torsion spring 30 to rotate. After the photovoltaic profiled plate 200 is installed, one end of the torsion spring 30 can apply force to the wall of the first mounting hole 4021 on the first side wall 402 or the wall of the first mounting hole 4021 on the second side wall 403, so that the first opening and closing piece 40 is reset.

[0046] Similarly, since the third sidewall 502 and the fourth sidewall 503 are both connected to the same surface of the second intermediate piece 501, and the third sidewall 502 and the fourth sidewall 503 are spaced apart, and the third sidewall 502 and the fourth sidewall 503 are both provided with second rotating holes 51, when the second opening piece 50 needs to be inserted into the rotating member 20, the second rotating holes 51 on the third sidewall 502 and the fourth sidewall 503 can be inserted into the rotating member 20, that is, the third sidewall 502 and the fourth sidewall 503 can be sleeved onto the rotating member 20 through the second rotating holes 51. The third sidewall 502 and / or the fourth sidewall 503 are provided with a second mounting hole 5021. The other end of the torsion spring 30 is located in the second mounting hole 5021 on the third sidewall 502 or the second mounting hole 5021 on the fourth sidewall 503. Thus, the other end of the torsion spring 30 can contact the third sidewall 502 or the fourth sidewall 503. When the second opening and closing piece 50 is subjected to the force of the concealed rib of the photovoltaic profiled plate 200, the second opening and closing piece 50 can drive the other end of the torsion spring 30 to rotate, thereby applying force to the other end of the torsion spring 30. That is, the hole wall of the second mounting hole 5021 on the third sidewall 502 or the hole wall of the second mounting hole 5021 on the fourth sidewall 503 applies force to the other end of the torsion spring 30, causing the other end of the torsion spring 30 to rotate. After the photovoltaic profiled plate 200 is installed, the other end of the torsion spring 30 can apply force to the wall of the second mounting hole 5021 on the third side wall 502 or the wall of the second mounting hole 5021 on the fourth side wall 503, so that the second opening and closing piece 50 is reset.

[0047] It should be noted that, in the embodiments of this application, the first mounting hole 4021 may be provided only on the first sidewall 402, or only on the second sidewall 403, or simultaneously on both the first sidewall 402 and the second sidewall 403. This embodiment of the application does not limit the scope of the application in this regard. Similarly, the second mounting hole 5021 may be provided only on the third sidewall 502, or only on the fourth sidewall 503, or simultaneously on both the third sidewall 502 and the fourth sidewall 503. This embodiment of the application does not limit the scope of the application in this regard. Method (2): The first opening and closing piece 40 includes a first intermediate piece 401, a first side wall 402 and a second side wall 403. The first side wall 402 and the second side wall 403 are both connected to the first surface of the first intermediate piece 401, and the first side wall 402 and the second side wall 403 are spaced apart. The first side wall 402 and the second side wall 403 are each provided with a first rotating hole 41. The first side wall 402 and the second side wall 403 are sleeved on the rotating member 20 through the first rotating hole 41. One end of the torsion spring 30 abuts against the first surface of the first intermediate piece 401. The second opening and closing piece 50 includes a second intermediate piece 501, a third side wall 502, and a fourth side wall 503. The third side wall 502 and the fourth side wall 503 are both connected to the first surface of the second intermediate piece 501, and the third side wall 502 and the fourth side wall 503 are spaced apart. The third side wall 502 and the fourth side wall 503 are each provided with a first rotating hole 41. The third side wall 502 and the fourth side wall 503 are sleeved on the rotating member 20 through the first rotating hole 41. One end of the torsion spring 30 abuts against the first surface of the second intermediate piece 501.

[0048] Since both the first sidewall 402 and the second sidewall 403 are connected to the first surface of the first intermediate piece 401, and the first sidewall 402 and the second sidewall 403 are spaced apart, and both the first sidewall 402 and the second sidewall 403 are provided with first rotating holes 41, when the first opening and closing piece 40 needs to be inserted into the rotating member 20, the first rotating holes 41 on the first sidewall 402 and the second sidewall 403 can be inserted into the rotating member 20, that is, the first sidewall 402 and the second sidewall 403 can be sleeved onto the rotating member 20 through the first rotating holes 41. One end of the torsion spring 30 abuts against the first surface of the first intermediate piece 401, so when the first opening and closing piece 40 is subjected to the force of the concealed rib of the photovoltaic profiled plate 200, the first opening and closing piece 40 can drive one end of the torsion spring 30 to rotate, thereby applying force to one end of the torsion spring 30, that is, the first intermediate piece 401 applies force to one end of the torsion spring 30, causing one end of the torsion spring 30 to rotate. After the photovoltaic profiled plate 200 is installed, one end of the torsion spring 30 can apply force to the first intermediate piece 401, so that the first opening and closing piece 40 is reset.

[0049] Similarly, since the third sidewall 502 and the fourth sidewall 503 are both connected to the first surface of the second intermediate piece 501, and the third sidewall 502 and the fourth sidewall 503 are spaced apart, and both the third sidewall 502 and the fourth sidewall 503 are provided with second rotating holes 51, when the second opening and closing piece 50 needs to be inserted into the rotating member 20, the second rotating holes 51 on the third sidewall 502 and the fourth sidewall 503 can be inserted into the rotating member 20, that is, the third sidewall 502 and the fourth sidewall 503 can be sleeved onto the rotating member 20 through the second rotating holes 51. The other end of the torsion spring 30 abuts against the first surface of the second intermediate piece 501, so when the second opening and closing piece 50 is subjected to the force of the concealed rib of the photovoltaic profiled plate 200, the second opening and closing piece 50 can drive the other end of the torsion spring 30 to rotate, thereby applying force to the other end of the torsion spring 30, that is, the second intermediate piece 501 applies force to the other end of the torsion spring 30, causing the other end of the torsion spring 30 to rotate. After the photovoltaic profiled plate 200 is installed, the other end of the torsion spring 30 can apply force to the second intermediate piece 501, so that the second opening and closing piece 50 is reset.

[0050] In this embodiment, a first mounting hole 4021 may be provided on the first sidewall 402 and / or the second sidewall 403, and a second mounting hole 5021 may be provided on the third sidewall 502 and / or the fourth sidewall 503. In this case, the other end of the torsion spring 30 may pass through the first mounting hole 4021 and the second mounting hole 5021. Of course, the first mounting hole 4021 may not be provided on the first sidewall 402 and / or the second sidewall 403, and the second mounting hole 5021 may not be provided on the third sidewall 502 and / or the fourth sidewall 503. In this case, the torsion spring 30 abuts against the first intermediate piece 401 and the second intermediate piece 501.

[0051] In some embodiments, the base 10 may include a base plate 11 for connecting to the roof, and the angle between the first intermediate piece 401 and the base plate 11 is an acute angle, and the angle between the second intermediate piece 501 and the base plate 11 is an acute angle.

[0052] When the angle between the first intermediate piece 401 and the base plate 11 is acute, and the angle between the second intermediate piece 501 and the base plate 11 is also acute, the first intermediate piece 401 and the second intermediate piece 501 are equivalent to having a certain degree of inclination. When the photovoltaic profiled plate 200 is installed on the photovoltaic profiled plate support 100, the concealed ribs of the photovoltaic profiled plate 200 have a certain degree of inclination. Thus, when the ribs contact the first opening piece 40 and the second opening piece 50, that is, when the concealed ribs contact the first intermediate piece 401 and the second intermediate piece 501, it is beneficial for the concealed ribs to drive the first intermediate piece 401 and the second intermediate piece 501 to rotate, which is beneficial for the concealed ribs to drive the first opening piece 40 and the second opening piece 50 to retract.

[0053] It should be noted that the angle between the first intermediate piece 401 and the base plate 11 is the angle between the extension line of the first intermediate piece 401 and the extension line of the base plate 11, and the angle between the second intermediate piece 501 and the base plate 11 is the angle between the extension line of the second intermediate piece 501 and the extension line of the base plate 11. For example, as... Figure 1 As shown, the included angle between the second intermediate piece 501 and the base plate 11 is... .

[0054] In some embodiments, the base 10 may include a base plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are both connected to the same surface of the base plate 11, and are spaced apart. Both the first side plate 12 and the second side plate 13 have rotating holes 101, through which a rotating member 20 passes. A torsion spring 30 is located between the first side plate 12 and the second side plate 13, and the base plate 11 is used for connection to the roof.

[0055] When the first side plate 12 and the second side plate 13 are both connected to the same side of the base plate 11, and the first side plate 12 and the second side plate 13 are spaced apart, and both the first side plate 12 and the second side plate 13 are provided with rotating holes 101, the rotating component 20 can pass through the rotating holes 101 on the first side plate 12 and the rotating holes 101 on the second side plate 13. This is equivalent to the rotating component 20 passing through the rotating holes 101 on the first side plate 12 and the rotating holes 101 on the second side plate 13 at the same time. Thus, the two ends of the rotating component 20 are supported by the first side plate 12 and the second side plate 13, so that the rotating component 20 can have a certain supporting effect and can be relatively stable. The torsion spring 30 is located between the first side plate 12 and the second side plate 13, and the first opening and closing piece 40 and the second opening and closing piece 50 are also located between the first side plate 12 and the second side plate 13. Thus, when the first opening and closing piece 40 and the second opening and closing piece 50 rotate, the rotating member 20 can provide certain support for the first side plate 12 and the second side plate 13, and both the first opening and closing piece 40 and the second opening and closing piece 50 can rotate relative to the rotating member 20.

[0056] In addition, in some embodiments, mounting holes 111 may be provided on the base plate 11, and the base plate 11 is connected to the roof through the mounting holes 111.

[0057] Because the base plate 11 has mounting holes 111, when connecting the base plate 11 to the roof, fasteners can pass through the mounting holes 111 to connect the base plate 11 to the roof, thus allowing the base plate 11 to be installed on the roof. In other words, by providing mounting holes 111 on the base plate 11, it is easy to install the base plate 11 on the roof.

[0058] It should be noted that the number of mounting holes 111 can be set according to actual needs. For example, the number of mounting holes 111 can be one or two. The specific number of mounting holes 111 is not limited in this embodiment. Furthermore, in this embodiment, the fastener can be a bolt.

[0059] In some embodiments, the rotating member 20 may include at least one of a screw and a pin.

[0060] When the rotating component 20 is a screw, it can pass through the rotating hole 101 on the base 10, and then be fixed in place by the fastener 21 to prevent it from coming out of the rotating hole 101. The fastener 21 can be a nut. When the rotating component 20 is a pin, it can pass through the rotating hole 101 on the base 10, and then be fixed in place by the fastener 21 to prevent it from coming out of the rotating hole 101. The fastener 21 can be an open pin, but other types of pins are also possible; this embodiment does not limit the specific type of pin used.

[0061] In this embodiment, since the first opening and closing piece 40 and the second opening and closing piece 50 are rotatably connected to the base 10 and are positioned opposite each other, the first opening and closing piece 40 can rotate relative to the base 10, allowing it to switch between a first position and a second position. The second opening and closing piece 50 can rotate relative to the base 10, allowing it to switch between a third position and a fourth position. Thus, when the photovoltaic profiled plate 200 is installed, the ribs of the concealed fastener of the photovoltaic profiled plate 200 press against the first opening and closing piece 40 and the second opening and closing piece 50, causing the first opening and closing piece 40 to rotate relative to the base 10, and the second opening and closing piece 50 to rotate relative to the base 10. The first opening and closing piece 40 switches from the first position to the second or fourth position, and the second opening and closing piece 50 switches from the third position to the fourth position, so that the first opening and closing piece 40 and the second opening and closing piece 50 obstruct the rib concealed fastener less, allowing the rib concealed fastener to be installed quickly. After the photovoltaic profiled sheet 200 is installed, the first opening and closing piece 40 switches from the second position to the first position, and the second opening and closing piece 50 switches from the fourth position to the third position. Thus, the first opening and closing piece 40 and the second opening and closing piece 50 block the ribs and prevent the photovoltaic profiled sheet 200 from separating from the photovoltaic profiled sheet 200 support 100. That is, in this embodiment of the application, by setting the first opening and closing piece 40 and the second opening and closing piece 50 to be rotatably connected to the base 10 respectively, and the first opening and closing piece 40 and the second opening and closing piece 50 being in opposite positions, the first opening and closing piece 40 and the second opening and closing piece 50 can change positions when installing the photovoltaic profiled plate 200, avoiding hard contact with the concealed ribs of the photovoltaic profiled plate 200. That is, the concealed ribs of the photovoltaic profiled plate 200 are not subjected to hard extrusion deformation, and the photovoltaic profiled plate support 100 is not subjected to hard extrusion deformation. This avoids the problem of damage to the photovoltaic profiled plate 200 and the photovoltaic profiled plate support 100 due to hard extrusion deformation during the installation of the photovoltaic profiled plate 200 on the photovoltaic profiled plate support 100.

[0062] like Figures 22 to 24 As shown, this application provides a roofing system including a photovoltaic profiled sheet 200 and a photovoltaic profiled sheet support 100 as described in any of the above embodiments. The photovoltaic profiled sheet 200 is mounted on the photovoltaic profiled sheet support 100, and the photovoltaic profiled sheet support 100 is mounted on the roof.

[0063] In this embodiment of the application, by setting the first opening and closing piece 40 and the second opening and closing piece 50 to be rotatably connected to the base 10 respectively, and the first opening and closing piece 40 and the second opening and closing piece 50 being positioned opposite each other, the first opening and closing piece 40 and the second opening and closing piece 50 can change positions when installing the photovoltaic profiled plate 200, avoiding hard contact with the concealed ribs of the photovoltaic profiled plate 200, that is, the concealed ribs of the photovoltaic profiled plate 200 are not subjected to hard extrusion deformation, and the photovoltaic profiled plate support 100 is not subjected to hard extrusion deformation. This avoids the problem of damage to the photovoltaic profiled plate 200 and the photovoltaic profiled plate support 100 due to hard extrusion deformation during the installation of the photovoltaic profiled plate 200 on the photovoltaic profiled plate support 100.

[0064] It should be noted that, as Figure 20 As shown, the photovoltaic profiled sheet 200 can be installed on the roof via the side support 300. Specifically, the photovoltaic profiled sheet support 100 can be installed on the roof purlin 400, and the side support 300 can also be installed on the roof purlin 400.

[0065] In some embodiments, the photovoltaic profiled sheet 200 has concealed ribs, which include opposing first corner portions 201 and second corner portions 202, with a receiving space between the first corner portions 201 and the second corner portions 202. A first opening / closing piece 40 and a second opening / closing piece 50 are located within the receiving space, with the first opening / closing piece 40 abutting against the first corner portion 201 and the second opening / closing piece 50 abutting against the second corner portion 202.

[0066] Since there is a space between the first corner 201 and the second corner 202, when installing the photovoltaic profiled plate 200, the first opening and closing piece 40 switches from the first position to the second position, and the second opening and closing piece 50 switches from the third position to the fourth position, which is equivalent to avoiding the first corner 201 and the second corner 202. After the installation is completed, both the first opening and closing piece 40 and the second opening and closing piece 50 are located in the space, and the first opening and closing piece 40 abuts against the first corner 201, and the second opening and closing piece 50 abuts against the second corner 202, so that the first opening and closing piece 40 and the second opening and closing piece 50 prevent the photovoltaic profiled plate 200 from separating from the photovoltaic profiled plate support 100.

[0067] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
