The support seat 1 comprises an integrally formed base portion 11, a main body portion 12 and a supporting portion 13, wherein the main body portion 12 is connected between the base portion 11 and the supporting portion 13. The base portion 11 can be fixed on the corrugation 301 of the roof tile 300, and the supporting portion 13 can abut against the bottom surface 202 of the photovoltaic module 200. Compared with the prior art, the locking device 100 of the utility model includes a support seat 1, a pressing block 2 and a fixing element 3. The base portion 11 of the support seat 1 is fixed to the corrugation 301 of the roof tile 300 by adhesive. It is not necessary to open a hole on the roof tile 300 so that it can be fixed on the roof tile 300, and will not damage the waterproof layer of the roof tile 300 and will not affect its waterproof performance. Moreover, the support seat 1 and the pressing block 2 are connected as a whole by the fixing element 3, and then the photovoltaic module 200 is fixed on the roof tile 300. The locking device 100 of the utility model has a simple structure, is easy to operate, and saves costs.

[0029] Please refer to Figures 3 to 6 , Fig. 9 and Fig.10 The base portion 11 is located below the main body portion 12 and the support portion 13 is located above the main body portion 12, thereby defining an up-down direction.

The purpose of providing the hole 120 is, on the one hand, to reduce weight, thereby reducing the weight of the entire support seat 1 and thus reducing costs, and on the other hand, to improve the tensile strength of the support seat 1 and further increase the stability of the screws connecting the support seat 1 and the pressure block 2.

[0030] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The support portion 13 includes two arms 131 extending in opposite directions from the top edge of the main body 12, and the two arms 131 extend the same distance in the left-right direction perpendicular to the up-down direction. In this way, the width of the support portion 13 is larger than the width of the main body 12 below, so that the support base 1 has a better load-bearing capacity.

[0031] Please continue to refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In the front-to-back direction perpendicular to both the up-down direction and the left-to-right direction, the hole 120 passes through the main body 12. That is, the hole 120 is set as a through hole that passes through the front and back, which is conducive to the molding operation.

[0032] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The base portion 11 includes two legs 111 extending from the bottom edge of the main body 12, each leg 111 having a root 1111 connected to the main body 12 and a free end 1112 away from the main body 12. The same base portion 11 has two free ends 1112 and two roots 1111, and the distance between the two free ends 1112 is greater than the distance between the two roots 1111. In this way, the shape of the base portion 11 can be adapted to the shape of the corrugation 301 of the roofing tile 300 and fixed on the corrugation 301.

[0033] As mentioned above, the fixing element 3 is a screw. Figure 3 and Figure 4 The support portion 13 is provided with a threaded hole 130 communicating with the hole 120, and the connection portion 21 is provided with a through hole 210, through which the screw passes and is positioned in the threaded hole 130. This arrangement facilitates the positioning connection between the support seat 1 and the pressing block 2, and on the other hand, the support seat 1 and the pressing block 2 are connected by screws, that is, the support seat 1 and the pressing block 2 are not fixed before the photovoltaic module 200 is installed in place, so that the photovoltaic module 200 can be adjusted in four directions on the support seat 1, front, back, left, and right.

[0034] Please refer to Figure 3 and Figure 4 The pressing block 2 includes an integrally formed connection portion 21, a first end portion and a second end portion, the first end portion and the second end portion are respectively located at opposite ends of the connection portion 21 and at least one of them is used to abut against the top surface 201 of the photovoltaic module 200. The main function of the pressing block 2 is to be fixed on the support seat 1 through the fixing element 3 so as to be able to press the top surface 201 of the photovoltaic module 200. The structure of the pressing block 2 includes the following two specific implementation schemes.

[0035] Please refer to Figure 3, is the first embodiment of the utility model locking device 100 applied to the edge of a photovoltaic module 200. In the first embodiment, the perforation 210 is a prefabricated strip hole, the first end includes a first end body 22 and a first vertical portion 211; the second end includes a second end body 23 and a second vertical portion 212; the first end body 22 and the second end body 23 extend in parallel in two planes, the horizontal portion 213 is located between the two planes where the first end body 22 and the second end body 23 are located in the up and down direction, the first end body 22 can be pressed on the top surface of the support portion 13, and the second end can be pressed on the top surface 201 of the photovoltaic module 200. The strip hole extends longitudinally in the front-to-back direction. With such a setting, the photovoltaic module 200 can be adjusted in the front-to-back direction on the support seat 1, that is, when the position of the pressing block 2 is adjusted as needed, the setting of the strip hole can ensure the correct installation of the screw. In other expressions, the first vertical portion 211 can be regarded as a part of the first end, and can also be regarded as a part of the connecting portion 21 from another angle. In other embodiments, the first end body 22 may also serve as the bottom of the first vertical portion 211 , that is, the first end body 22 does not extend in a plane, and the first vertical portion 211 is directly pressed onto the top surface of the support portion 13 .

[0036] Please refer to Figure 4 , is the second embodiment of the utility model locking device 100 applied to the edge of two adjacent photovoltaic modules 200. In the second embodiment, the through hole 210 is a self-tapping screw hole, the first end includes a first end body 22 and a first vertical portion 211; the second end includes a second end body 23 and a second vertical portion 212; the first end body 22 and the second end body 23 extend in parallel in two planes, the horizontal portion 213 is located below the same plane where the first end body 22 and the second end body 23 are located in the up and down direction, and the first end body 22 and the second end body 23 can be respectively pressed on the top surface 201 of the two adjacent photovoltaic modules 200. In this way, when the photovoltaic module 200 is difficult to install or misaligned on the support seat 1, the position of the photovoltaic module 200 can be adjusted and then locked with self-tapping screws, that is, no hole for screws to pass through is pre-set, but the photovoltaic module 200 is locked in the correct position of the support seat 1 as needed. It can be understood that the first vertical portion 211 can be regarded as a part of the first end, and can also be regarded as a part of the connecting portion 21 from another angle; similarly, the second vertical portion 212 can be regarded as a part of the second end, and can also be regarded as a part of the connecting portion 21 from another angle.

[0037] Regardless of the implementation scheme, the connecting portion 21 includes a horizontal portion 213, and the through hole 210 is arranged on the horizontal portion 213. In this way, the connection between the first end and the second end can be better, faster and simpler, that is, the pressing block 2 has the beneficial effects of simple structure and convenient use. Please continue to refer to Figure 3 and Figure 4 The through hole 210 is one of a prefabricated hole and a self-drilling hole. A prefabricated hole means that before the screw is screwed in, a hole for the screw to pass through is pre-set; a self-drilling hole means that before the screw is screwed in, there is no pre-set hole for the screw to pass through, but a hole is screwed open on the horizontal portion 213 of the connecting portion 21 when the screw is screwed in.

[0038] Understandable, please refer to Figure 1 and Figure 2 In the present invention, the support seat 1 is used to connect and fix the photovoltaic module 200 to the roofing tile 300 at the short side of the roofing tile 300 (the short side is the side with the corrugation 301). When the photovoltaic module 200 exceeds the edge position of the roofing tile 300 or the position of the photovoltaic module 200 deviates, the locking device 100 of the present invention can be installed and can be adjusted according to the construction site, which has great freedom and increases the scope of application; further, the base portion 11 of the support seat 1 is arranged with thermoplastic polyolefin (TPO, Thermoplastic polyolefin) material on the side facing the corrugation 301 of the roofing tile 300, so that the support seat 1 can be fixed on the roofing tile 300 by hot air welding, ensuring that the structure of the locking device 100 of the present invention on the roofing tile 300 is stable and not easy to fall off.

[0039] In summary, the locking device 100 of the utility model includes a support seat 1, a pressing block 2 and a fixing element 3. The base portion 11 of the support seat 1 can be fixed on the corrugation 301 of the roof tile 300 without drilling holes on the roof tile 300, and the waterproof layer of the roof tile 300 will not be damaged and its waterproof performance will not be affected. Moreover, the support seat 1 and the pressing block 2 are connected as a whole through the fixing element 3, and then the photovoltaic module 200 is fixed on the roof tile 300. The locking device 100 of the utility model has a simple structure, convenient operation and cost saving. The support seat 1 is provided with a main body 12 with a certain thickness, which can increase the support strength of the support seat 1, and is also convenient for the opening of the threaded hole 130, and the locking method is more convenient; at the same time, a hole 120, i.e. a weight-reducing hole, is also provided on the main body 12, which can reduce the cost of the locking device 100 of the utility model.
