[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In this invention, by setting up an installation mechanism, the lightning protection flat iron is placed in the installation hole, and then the support plate is pushed to move to the left. The support plate moves in the positioning groove, and then the positioning block is controlled to move up and down in the rectangular sleeve. The positioning block moves down and gets into the positioning groove, thereby effectively fixing the support plate. At this time, the installation block can squeeze the lightning protection flat iron, so that the lightning protection flat iron is tightly attached to the right side of the prefabricated component, thereby achieving the purpose of fixing the lightning protection flat iron. Welding is not required, the operation is simple and convenient and saves construction time.

[0025] 2. In this invention, by setting a side plate, a slot, a pressing block, and a positioning mechanism, when the lightning protection flat iron moves to the left, the pressing block will gradually be inserted into the first through hole, and the pressing block will press the two arc-shaped blocks. The two arc-shaped blocks will move away from each other due to the pressing. The arc-shaped blocks will drive the locking block to move through the sliding rod. The two locking blocks will move away from each other and be inserted into the front and rear slots respectively. At this time, the lightning protection flat iron can be effectively and tightly fixed. Welding is not required, but the fixing effect is better. By setting a spring, the spring can extend through its own elasticity to push the arc-shaped blocks to move. The arc-shaped blocks will drive the locking block to stay in the position in the second through hole through the sliding rod, preventing the locking block from automatically dislodging from the second through hole and being exposed outside, so as not to affect the installation of the lightning protection flat iron.

[0026] 3. In this invention, by setting a fixing mechanism, when it is necessary to install the lightning protection flat iron and the metal plate together, the metal plate is attached to the lightning protection flat iron, and then the two pressing rods are respectively passed through the two limiting holes. Then, one end of the two pressing rods is pressed down. Under the action of the connecting rod and one end of the pressing rod, the pressing rod can rotate. At the same time, the first hemispherical block is fixed in the first hemispherical groove. At this time, the fixing plate is fixed and pressed to the left. The fixing plate drives the pad to move to the left. The pad presses the metal plate so that the metal plate can be stably attached to the lightning protection flat iron. The silicone pad can appropriately shrink and buffer the pressure to avoid damage caused by the strong mutual compression between the metal plate and the lightning protection flat iron. The pressing rod is continuously controlled to move so that the second hemispherical block can be inserted into the second hemispherical groove. At this time, the fixing block can fix the other end of the pressing rod, so that the metal plate can be tightly attached to the lightning protection flat iron. Attached Figure Description

[0037] The specific implementation method is as follows: by setting the installation mechanism 2, the lightning protection flat iron 3 is placed in the installation hole 26, and then the support plate 24 is pushed to move to the left. The support plate 24 moves in the positioning groove 23. Then, the positioning block 21 is controlled to move up and down in the rectangular sleeve 22. The positioning block 21 moves down and is inserted into the positioning groove 23, thereby effectively fixing the support plate 24. At this time, the installation block 25 can squeeze the lightning protection flat iron 3, so that the lightning protection flat iron 3 is tightly attached to the right side of the prefabricated component 1, thereby achieving the purpose of fixing the lightning protection flat iron 3. Welding is not required. The operation is simple and convenient and saves construction time.

[0038] The installation mechanism 2 is equipped with a lightning protection flat iron 3, and the lightning protection flat iron 3 is equipped with a positioning mechanism 6. Multiple positioning mechanisms 6 are arranged evenly from top to bottom. Each positioning mechanism 6 includes a first through hole 61 inside the lightning protection flat iron 3.

Side plates 5 are provided on both the front and rear sides of the precast component 1. The side plates 5 are fixedly connected to the right side of the precast component 1.

[0039] The specific implementation method is as follows: By setting the side plate 5, the slot, the pressing block 4 and the positioning mechanism 6, when the lightning protection flat iron 3 moves to the left, the pressing block 4 will gradually be inserted into the first through hole 61, and the pressing block 4 will press the two arc-shaped blocks 62. The two arc-shaped blocks 62 will move away from each other due to the pressing. The arc-shaped blocks 62 will drive the locking block 67 to move through the sliding rod 64. The two locking blocks 67 will move away from each other and be inserted into the front and rear slots respectively. At this time, the lightning protection flat iron 3 can be effectively and tightly fixed. Welding is not required but the fixing effect is better. By setting the spring 63, the spring 63 can extend through its own elasticity to push the arc-shaped blocks 62 to move. The arc-shaped blocks 62 will drive the locking block 67 to stay in the position in the second through hole 66 through the sliding rod 64, preventing the locking block 67 from automatically dislodging from the second through hole 66 and being exposed outside, so as not to affect the installation of the lightning protection flat iron 3.

[0040] A fixing mechanism 7 is provided on the right side of the lightning protection flat iron 3. The fixing mechanism 7 includes a metal plate 73 attached to the right side of the lightning protection flat iron 3. A silicone pad 72 is fixedly connected to the right side of the metal plate 73. A pad plate 71 is fixedly connected to the right side of the silicone pad 72. Fixing plates 74 are fixedly connected to both the front and rear sides of the left side of the pad plate 71. Limiting holes 78 are opened in the fixing plates 74. A first hemispherical block 77 is fixedly connected to the left side of the inner wall of the limiting hole 78. 7 is inserted into the first hemispherical groove 76 on the left side of the pressing rod 79. One end of the pressing rod 79 is hinged to a connecting rod 75, which is fixedly connected to the right side of the lightning protection flat iron 3. The other end of the pressing rod 79 is fixedly connected to a second hemispherical block 710. The second hemispherical block 710 is inserted into the second hemispherical groove 711 on one side of the fixing block 712. The fixing block 712 is fixedly connected to the right side of the lightning protection flat iron 3. The right side of the fixing block 712 is set as an arc surface.

[0041] The specific implementation method is as follows: By setting the fixing mechanism 7, when it is necessary to install the lightning protection flat iron 3 and the metal plate 73 together, the metal plate 73 is attached to the lightning protection flat iron 3, and then the two pressing rods 79 are respectively passed through the two limiting holes 78. Then, one end of the two pressing rods 79 is pressed down and moved downward. Under the action of the connecting rod 75 and one end of the pressing rod 79 being hinged, the pressing rod 79 can rotate. At the same time, the first hemispherical block 77 is fixed in the first hemispherical groove 76. At this time, the fixing plate 74 is fixed and pressed to the left, and the fixing plate 74 drives... The pad 71 moves to the left, pressing the metal plate 73 so that the metal plate 73 can be stably attached to the lightning protection flat iron 3. The silicone pad 72 can appropriately shrink and buffer the pressure to prevent the metal plate 73 and the lightning protection flat iron 3 from being damaged by strong mutual compression. The pressing rod 79 is continuously controlled to move, so that the second hemisphere block 710 can be inserted into the second hemisphere groove 711. At this time, the fixing block 712 can fix the other end of the pressing rod 79, so that the lightning protection flat iron 3 can be tightly attached to the precast component 1 without loosening.

[0042] Working principle: In use, place the lightning protection flat iron 3 in the mounting hole 26, then push the support plate 24 to the left. The support plate 24 moves into the positioning groove 23. Then, control the positioning block 21 to move up and down within the rectangular sleeve 22. The positioning block 21 moves down and engages in the positioning groove 23, thus effectively fixing the support plate 24. At this time, the mounting block 25 can squeeze the lightning protection flat iron 3, making the lightning protection flat iron 3 tightly adhere to the right side of the prefabricated component 1, achieving the purpose of fixing the lightning protection flat iron 3. When the lightning protection flat iron 3 moves to the left, the squeezing block 4 will gradually engage into the first through hole 61. The squeezing block 4 will squeeze the two arc-shaped blocks 62. The two arc-shaped blocks 62 will move away from each other due to the squeezing. The arc-shaped blocks 62 drive the locking block 67 to move through the sliding rod 64. The two locking blocks 67 move away from each other and engage into the front and rear locking slots respectively. At this time, the lightning protection flat iron 3 can be effectively and tightly fixed. When it is necessary to install the lightning protection flat iron 3 with the metal plate 73, The metal plate 73 is attached to the lightning protection flat iron 3. Then, the two pressing rods 79 are passed through the two limiting holes 78 respectively. Then, one end of the two pressing rods 79 is pressed down and moved downward. Under the action of the connecting rod 75 and the pressing rod 79, the pressing rod 79 can rotate. At the same time, the first hemispherical block 77 is fixed in the first hemispherical groove 76. At this time, the fixing plate 74 is fixed and pressed to the left. The fixing plate 74 drives the pad 71 to move to the left. The pad 71 presses the metal plate 73 so that the metal plate 73 can be stably attached to the lightning protection flat iron 3. The silicone pad 72 can appropriately shrink and buffer the pressure to avoid damage caused by the strong mutual compression between the metal plate 73 and the lightning protection flat iron 3. The pressing rod 79 is continuously controlled to move so that the second hemispherical block 710 can be inserted into the second hemispherical groove 711. At this time, the fixing block 712 can fix the other end of the pressing rod 79, so that the metal plate 73 can be tightly attached to the lightning protection flat iron 3.
