[0025] See also Figures 1 to 5 In the utility model, a locking component for a metal roof panel comprises two adjacent roof panels 1, a locking support 2 and a locking buckle plate 3 arranged between the two adjacent roof panels 1, the locking support 2 comprises a fixed base 21 connected to the structural C-shaped steel by bolts, a T-shaped component 22 is vertically arranged at the center of the top of the fixed base 21, and a locking head 23 is arranged at the end of the T-shaped component 22; an inner locking edge 11 is arranged on one side of the roof panel 1 to fit the outer wall of the locking head 23, and an outer locking edge 12 is arranged on the other side of the roof panel 1, and the outer locking edge 12 can be buckled on the outer wall of the inner locking edge 11 of another roof panel 1; the locking buckle plate 3 is buckled on the inner locking edge 11 and the outer locking edge 12, and two elastic sealing sheets 4 are arranged on the inner side of the locking buckle plate 3, and when the locking buckle plate 3 is buckled on the inner locking edge 11 and the outer locking edge 12, the two elastic sealing sheets 4 are respectively fitted with the outer walls of the inner locking edge 11 and the outer locking edge 12.
[0026] In this embodiment, preferably, the lock head 23 and the T-shaped member 22 are integrally formed components, and grooves 231 are recessed inwardly at positions on both sides of the bottom of the lock head 23 near the T-shaped member 22. The lock head 23 and the T-shaped member 22 cooperate with the grooves 231 to form an arrow-shaped component; embedded folds 13 are formed on the inner lock edge 11 and the outer lock edge 12. When the inner lock edge 11 is buckled onto the outer wall of the lock head 23 and the outer lock edge 12 is buckled onto the inner lock edge 11, the embedded folds 13 can be embedded in the grooves 231.
[0027] Specifically, an embedded fold 13 embedded in the groove 231 is processed on the inner lock edge 11 and the outer lock edge 12. The cooperation between the embedded fold 13 and the groove 231 can ensure the tightness of the connection between the inner lock edge 11, the outer lock edge 12 and the lock head 23, ensure that the inner lock edge 11 is tightly buckled on the surface of the lock head 23, and ensure that the outer lock edge 12 is tightly buckled on the surfaces of the lock head 23 and the inner lock edge 11, avoid looseness between the inner lock edge 11, the outer lock edge 12 and the lock head 23, and enhance the tightness of the structure.
[0028] In this embodiment, preferably, the top of the lock head 23, between the side wall of the lock head 23 and the groove 231, and above the embedded fold 13 are all configured as rounded curved surfaces;
[0029] Specifically, a rounded curved surface is set to achieve a transition connection to avoid damage to the corresponding structure caused by the sharp corners of the transition part.
[0030] In this embodiment, preferably, an elastic sealing strip 5 is provided in the groove 231. When the embedded fold 13 is embedded in the groove 231, the elastic sealing strip 5 is squeezed and fits the surface of the lock head 23 and the T-shaped member 22;
[0031] Specifically, after the inner lock edge 11 and the outer lock edge 12 are installed, the embedded fold 13 is embedded in the groove 231 and squeezes the elastic sealing strip 5. The elastic sealing strip 5 elastically fits the surface of the lock head 23, the T-shaped member 22 and the embedded fold 13, and the elastic sealing strip 5 plays a sealing role to reduce the risk of leakage.
[0032] In this embodiment, preferably, the two ends of the locking plate 3 are integrally formed with barbs 31, and when the locking plate 3 is buckled on the inner locking edge 11 and the outer locking edge 12, the two barbs 31 can be respectively embedded in the embedded folds 13;

The lock buckle plate 3 strengthens and protects the inner lock edge 11 and the outer lock edge 12 to prevent wind force from directly acting on the joint between the inner lock edge 11 and the outer lock edge 12, thereby improving the wind resistance and covering the gap to make it more beautiful.
[0034] In this embodiment, preferably, a side of the elastic sealing sheet 4 away from the inner wall of the locking edge buckle plate 3 is provided with a linear array of trapezoidal notches, and the trapezoidal notches form a plurality of bosses on the side of the elastic sealing sheet 4 away from the inner wall of the locking edge buckle plate 3;
[0035] Specifically, after the locking buckle plate 3 is installed, the elastic sealing sheet 4 can be squeezed to deform, and the side of the elastic sealing sheet 4 with the trapezoidal notch contacts the outer locking edge 12 and the inner locking edge 11. As the connection becomes tighter, the elastic sealing sheet 4 is deformed and fits tightly against the outer locking edge 12 and the inner locking edge 11, achieving a better sealing effect.
[0036] The working principle and use process of this utility model:
[0037] First, the fixed base 21 and the T-shaped member 22 are installed, and then the inner lock edge 11 of the roof panel 1 is buckled on the outer side of the lock head 23 at the end of the T-shaped member 22 by using a tool, and the embedded folds 13 on the inner lock edge 11 are embedded in the groove 231, and then the outer lock edge 12 of the roof panel 1 is buckled on the outer side of the inner lock edge 11 by using a tool, and the embedded folds 13 on the outer lock edge 12 are also embedded in the corresponding groove 231, and the tightness of the connection between the inner lock edge 11 and the outer lock edge 12 and the lock head 23 can be ensured by the cooperation of the embedded folds 13 and the groove 231, and the inner lock edge 11 is tightly buckled on the surface of the lock head 23, and the outer lock edge 12 is tightly buckled on the surface of the lock head 23 and the inner lock edge 11, so as to avoid looseness between the inner lock edge 11 and the outer lock edge 12 and the lock head 23, and strengthen the tightness of the structure;
[0038] Then, the locking gusset plate 3 is buckled on the inner locking edge 11 and the outer locking edge 12, and the barb 31 of the locking gusset plate 3 is embedded in the embedded fold 13. The locking gusset plate 3 strengthens and protects the inner locking edge 11 and the outer locking edge 12, preventing the wind force from directly acting on the joint between the inner locking edge 11 and the outer locking edge 12, improving the wind resistance, and covering the gap to make it more beautiful;
[0039] In the above process, the elastic sealing strip 5 and the elastic sealing sheet 4 are squeezed and fit with the corresponding structural surface, which has a good sealing effect and effectively reduces the hidden danger of leakage.
