[0045] 1 to 10 , an embodiment of the utility model provides a mounting fixture, which includes a support seat 100, a transmission member 200, a locking member 300 and two clamping members 400. The support seat 100 includes a fixing plate 110 and a connecting plate 120 which are arranged at an angle; the transmission member 200 is rotatably connected to the fixing plate 110; the locking member 300 is transmission-connected to the transmission member 200; the two clamping members 400 are rotatably connected to the connecting plate 120 and are distributed on opposite sides of the locking member 300, and a clamping opening is defined between the two clamping members 400; wherein each clamping member 400 is rotationally abutted against the locking member 300, and when the transmission member 200 rotates relative to the fixing plate 110, the locking member 300 can move along the axial direction of the transmission member 200, and the two clamping members 400 rotate under the action of the locking member 300 to adjust the opening size of the clamping opening.

[0046] The technical solution provides a mounting fixture, wherein the support seat 100 is used to support the transmission member 200 and the locking member 300. The fixing plate 110 is used to be fixedly connected to the purlin connected to the photovoltaic module to achieve the fixed connection between the photovoltaic module and the color steel tile; the connecting plate 120 is used to connect the clamping member 400. The transmission member 200 is rotatably connected to the fixing plate 110, and the locking member 300 is transmission-connected to the transmission member 200, so that when the transmission member 200 rotates relative to the fixing plate 110, the locking member 300 moves along the axial direction of the transmission member 200. The two clamping members 400 are rotatably connected to the connecting plate 120 and are rotationally abutted with the locking member 300, so that when the locking member 300 moves relative to the fixing plate 110, the clamping member 400 can be driven to rotate, so that the opening size of the clamping opening formed by the two clamping members 400 can be adjusted, and then the color steel tile is clamped through the clamping opening of the clamping member 400 to achieve the connection between the purlin and the color steel tile. The purlins and the color steel tiles are fixedly connected by the above-mentioned bite clamping method, and there is no need to drill holes on the color steel tile roof, which will not damage the color steel tile roof. In addition, during the entire installation process, only the transmission member 200 needs to be rotated to achieve the clamping of the color steel tile by the clamping member 400, and no nut needs to be installed. During installation, the installation fixture can be fixed on the color steel tile before locking the transmission member 200, and the transmission member 200 can be locked after the position is determined, thereby improving the installation efficiency.

[0047] It is understandable that the angle between the fixed plate 110 and the connecting plate 120 can be an obtuse angle or a right angle, preferably, the angle between the two is a right angle. In this embodiment, the transmission member 200 is a rod-shaped structure. When the transmission member 200 rotates relative to the fixed plate 110 so that the locking member 300 moves toward the fixed plate 110, the two clamping members 400 move toward each other under the force of the locking member 300, thereby making the opening of the clamping port smaller, and then the color steel tile is clamped by the two clamping members 400.

[0048] As shown in Figures 2 to 5 and Figures 9 and 10, in one embodiment, the locking member 300 is constructed as a square structure, and limiting protrusions 310 are provided on the edges of the opposite sides of the locking member 300; the clamping member 400 includes a connecting portion 410 and a clamping portion 420 that are interconnected, the connecting portion 410 is constructed as a square structure, and a limiting groove 411 is provided on the connecting portion 410, the limiting groove 411 is matched with the limiting protrusion 310, and the clamping portion 420 can rotate around the limiting protrusion 310.

[0049] By setting the locking member 300 to a square structure and setting the connecting portion 410 of the clamping member 400 to a square structure, the mutual limitation between the clamping member 400 and the locking member 300 is achieved through the concave-convex cooperation between the limiting groove 411 and the limiting protrusion 310. Under the limiting action of the clamping member 400, when the transmission member 200 rotates relative to the fixed member, the locking member 300 can only move along the axis of the transmission member 200, but cannot rotate around the axis of the transmission member 200. And through the concave-convex cooperation between the limiting groove 411 and the limiting protrusion 310, when the locking member 300 moves along the axis direction of the transmission member 200, the clamping member 400 rotates around the limiting protrusion 310 under the action of the locking member 300, thereby achieving the adjustment of the opening size of the clamping opening of the clamping member 400.

[0050] As shown in FIG. 4 , FIG. 8 and FIG. 10 , in one embodiment, the groove side of the limiting groove 411 facing the transmission member 200 is configured as an inclined surface, and the groove width of the limiting groove 411 gradually increases from the groove bottom to the groove opening. Further, the limiting groove 411 is configured as a trapezoidal groove. The limiting protrusion 310 is configured as a semi-cylindrical structure; the inclined surface of the limiting groove 411 is tangent to the semi-cylindrical surface of the limiting protrusion 310. By configuring the limiting protrusion 310 of the locking member 300 as a semi-cylindrical structure, configuring the limiting groove 411 of the clamping member 400 as a trapezoidal groove, and configuring the semi-cylindrical limiting protrusion 310 to be tangent to the groove bottom and inclined surface of the trapezoidal groove, when the locking member 300 moves upward under the drive of the transmission member 200, the clamping member 400 rotates around the cylindrical protrusion, and the tangent point position changes with the rotation, so that the biting process of the clamping member 400 and the color steel tile is not significantly hindered. Furthermore, since the limiting protrusion 310 of the locking member 300 is tangent to the groove bottom and the side surface of the trapezoidal groove, the clamping member 400 has better self-locking property when engaging with the color steel tile.

[0051] As shown in FIGS. 4 to 6 , in one embodiment, the installation fixture further includes a rotating shaft 500, which is fixedly connected to the connecting plate 120, and the clamping portion 420 is rotatably connected to the rotating shaft 500. By fixing the rotating shaft 500 to the connecting plate 120, the clamping portion 420 of the clamping member 400 is rotatably connected to the rotating shaft 500, so that the clamping member 400 can rotate relative to the support seat 100, so that when the locking member 300 moves with the transmission member 200, the clamping member 400 is driven to rotate by the locking member 300, so as to adjust the opening size of the clamping port, and then clamp the color steel tile by the clamping member 400. Of course, in other embodiments, the rotating shaft 500 can be fixedly connected to the clamping member 400, and the rotating shaft 500 can be rotatably connected to the connecting plate 120.

[0052] In one embodiment, the transmission member 200 is threadedly connected to the fixed plate 110; the locking member 300 is threadedly connected to the transmission member 200. With such a configuration, when a tangential force is applied to the transmission member 200, the transmission member 200 can rotate relative to the fixed plate 110, and under the combined effect of the transmission force of the transmission member 200 and the limiting effect of the clamping member 400, the transmission locking member 300 moves along the axial direction of the transmission member 200 and drives the clamping member 400 to rotate, thereby clamping the color steel tile. With such a configuration, the clamp can be clamped by using a transmission member 200 with a thread, and during the installation process, it is only necessary to tighten the transmission member 200, and there is no need to install a nut during the installation process, thereby improving the installation efficiency.

[0053] As shown in FIG. 7 , in one embodiment, the clamping surface of the clamping portion 420 at one end away from the connecting portion 410 is constructed as a concave-convex structure. By providing a concave-convex structure on the clamping surface to increase the friction between the clamping surface and the contact surface of the color steel tile, the reliability of clamping is improved. Furthermore, a clamping groove 421 is configured on the clamping portion 420, and the shape of the clamping groove 421 matches the structure of the mounting tile. By setting the shape of the clamping groove 421 on the clamping portion 420 to match the outer contour of the wave crest of the mounting tile, that is, the color steel tile, the tightness of the clamping member 400 clamping the color steel tile can be improved.

[0054] As shown in FIG. 7 , in one embodiment, the fixing plate 110 is further provided with a mounting hole 111, which is configured as a strip hole. The fixing plate 110 is provided with a connection hole 112 for connecting with the transmission member 200, and the connection hole 112 is provided with a countersunk hole 113, which is connected with the connection hole 112, and the countersunk hole 113 is used to accommodate the end of the transmission member 200. By providing a strip hole on the fixing plate 110, the fixing plate 110 is connected to the purlin by bolts, and the mounting hole 111 is provided as a strip hole, so as to adjust the position of the bolt during installation, thereby improving the installation efficiency. In this embodiment, the connection hole 112 is a threaded hole to achieve threaded transmission connection with the transmission member 200. The countersunk hole 113 is provided on the connection hole 112 so that the end of the transmission member 200 is not exposed on the top surface of the fixing plate 110, thereby preventing the transmission member 200 from interfering with the purlin.

[0055] An embodiment of the utility model further provides a photovoltaic system, which includes the above-mentioned mounting fixture, and the photovoltaic system also includes photovoltaic components and purlins. The photovoltaic components are installed on the purlins, and the mounting fixture is connected to the purlins. The mounting fixture is used to clamp the color steel tiles.

[0056] The photovoltaic system provided in this embodiment adopts the above-mentioned installation fixture, and realizes the fixed connection between the purlin and the color steel tile by the above-mentioned bite clamping method, without drilling holes on the color steel tile roof, and will not damage the color steel tile roof. Moreover, during the entire installation process, it is only necessary to rotate the transmission member 200 to realize the clamping of the color steel tile by the clamping member 400, and there is no need to install nuts. Moreover, during installation, the installation fixture can be fixed on the color steel tile before locking the transmission member 200, and the transmission member 200 can be locked after the position is determined, thereby improving the installation efficiency. The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
