DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a safe steel structure node component, such as Figures 1 to 3As shown, it includes a support steel 1, and a steel beam 2 is inserted at the center of both sides of the support steel 1. The overall shape of the steel beam 2 is set to a T-shaped structure, and a cross plate 3 supporting the steel beam 2 is fixed on both sides of the support steel 1. Two folding plates 4 are arranged opposite to each other inside the support steel 1. The two folding plates 4 correspond to the two steel beams 2 one by one, and the folding plates 4 are fixedly installed on the inner wall of the support steel 1 by bolts. The two folding plates 4 are relatively installed on the inner wall of the support steel 1 by bolts, and the inner end of the steel beam 2 is correspondingly inserted into the side of the support steel 1 until the inner end of the steel beam 2 fits with the folding plate 4. At this time, the bottom of the steel beam 2 is placed on the top surface of the cross plate 3. The length of the steel beam 2 inserted into the support steel 1 is limited by the folding plate 4, and the support of the cross plate 3 prevents the steel beam 2 from tilting.

[0027] A T-shaped frame 5 is arranged between the two folding plates 4. The bottom of the two sides of the T-shaped frame 5 is placed on the top surfaces of the two folding plates 4. The front and rear sides of the T-shaped frame 5 are fixedly installed inside the supporting steel 1 by screws 6. A rotating rod 7 is inserted at the center of the T-shaped frame 5. A rotating disk 8 is fixed on the top of the rotating rod 7. The bottom end of the rotating rod 7 passes through the T-shaped frame 5, and a gear 9 is fixed on the surface of the rotating rod 7. The bottom surface of the T-shaped frame 5 is provided with a supporting component that limits the bottom end of the rotating rod 7. An inner groove 10 corresponding to the gear 9 is arranged inside the T-shaped frame 5. Both sides of the T-shaped frame 5 are provided with moving components corresponding to the gear 9. The moving components include an insert rod 11. The inner end surface of the steel beam 2 is provided with a slot 12 corresponding to the insert rod 11. The rotating rotating rod 7 uses the gear 9 and the moving component to make the insert rod 11 correspondingly inserted into the slot 12 at the inner end of the steel beam 2. The folding plate 4 corresponds to the inner end of the steel beam 2, and the folding plate 4 cooperates with the insert rod 11 to limit the steel beam 2. After the two folding plates 4 are installed inside the supporting steel 1, the T-shaped frame 5 is placed between the two folding plates 4, and the bottom surfaces of the two sides of the T-shaped frame 5 are respectively attached to the top surfaces of the two folding plates 4, and the T-shaped frame 5 is fixed inside the supporting steel 1 by multiple screws 6 to ensure the stability of the T-shaped frame 5 inside the supporting steel 1. The rotating turntable 8 is rotated, and the rotating turntable 8 drives the gear 9 to rotate by the rotating rod 7. The rotating gear 9 and the moving parts cooperate to move the plug rod 11. At this time, the two plug rods 11 are away from each other, and the inner side ends of the steel beam 2 are correspondingly inserted into the side of the supporting steel 1. The turntable 8 is rotated in the opposite direction, and the rotating rod 7 uses the gear 9 to make the two plug rods 11 approach each other until the plug rod 11 is correspondingly inserted into the slot 12 of the steel beam 2. The plug rod 11 cooperates with the folding plate 4 to limit the inner side of the steel beam 2, so that the steel beam 2 can be quickly fixedly connected to the supporting steel 1, thereby improving the installation efficiency.

[0028] Figures 2 to 5In the figure, the moving part includes a moving block 13, and side grooves are provided on both sides of the T-shaped frame 5. The moving block 13 is inside the side groove. A tooth plate 14 is fixed to the inner end of the moving block 13, and the tooth plate 14 is engaged with the gear 9. An inner rod 15 that passes through the moving block 13 is embedded in the side groove, and a spring 16 is sleeved on the surface of the inner rod 15. One end of the spring 16 is connected to the moving block 13, and the other end of the spring 16 is connected to the inner wall of the side groove, and the spring 16 is in a compressed state. When the rotating rotating rod 7 drives the gear 9 to rotate inside the inner groove 10, the meshing effect of the rotating gear 9 and the tooth plate 14 causes the moving block 13 to rotate inside the side groove. Since the two moving blocks 13 are relatively staggered, when the gear 9 rotates counterclockwise, the cooperation between the gear 9 and the tooth plate 14 causes the two moving blocks 13 to move away from each other, and the moving block 13 squeezes the spring 16 on the surface of the inner rod 15 during the movement until the moving block 13 cannot move; the torsional force applied to the rotating rod 7 is released, and the elastic force of the spring 16 pushes the tooth plate 14 to move through the moving block 13, and the tooth plates 14 moving toward each other cause the gear 9 to rotate clockwise until the insertion rod 11 is correspondingly inserted into the slot 12.

[0029] The outer side of the moving block 13 is fixed with a side block 17, and the plug rod 11 is installed on the inner side of the side block 17. The elastic force of the spring 16 pushes the side block 17 to approach the steel beam 2 through the moving block 13 until the plug rod 11 on the side block 17 is correspondingly inserted into the slot 12 at the inner end of the steel beam 2. When the moving block 13 moves, the moving moving block 13 drives the plug rod 11 to move synchronously through the side block 17, and the relative distance between the two moving blocks 13 is adjusted through the meshing cooperation of the gear 9 and the tooth plate 14. The side groove and the inner rod 15 cooperate to limit the moving block 13 to avoid the moving block 13 from being offset inside the side groove, so that the plug rod 11 corresponds to the slot 12 on the surface of the steel beam 2 in real time. The side block 17 is located outside the T-shaped frame 5, and the rotating rod 7 is rotated. The rotating rod 7 uses the gear 9 and the tooth plate 14 to make the two moving blocks 13 approach or move away from each other.

[0030] exist Figure 2 , Figure 4 and Figure 6In the embodiment, the support component includes two vertical rods 18 arranged opposite to each other, a circular plate is fixed at the bottom end of the vertical rod 18, the overall shape of the vertical rod 18 is set as a rectangular parallelepiped structure, and a sleeve frame 19 is sleeved on the surface of the vertical rod 18, a first elastic piece 20 is arranged at the bottom of the sleeve frame 19, the bottom end of the first elastic piece 20 is connected to the top surface of the circular plate, the top end of the first elastic piece 20 is in contact with the bottom surface of the sleeve frame 19, and the first elastic piece 20 is in a compressed state. A limiting rod 21 is embedded in the sleeve frame 19, and a vertical groove corresponding to the limiting rod 21 is arranged on the surface of the vertical rod 18, and a second elastic piece 22 is arranged on the outer side of the vertical rod 18, one end of the second elastic piece 22 is connected to the outer side of the vertical rod 18, and the other end of the second elastic piece 22 is connected to the inner wall of the sleeve frame 19, and the second elastic piece 22 is in a stretched state. A flat plate 23 is arranged between the two vertical rods 18 , the top surface of the flat plate 23 is in contact with the bottom end of the rotating rod 7 , rotating plates 24 are arranged on both sides of the flat plate 23 , the top end of the rotating plate 24 is hinged to the flat plate 23 , and the bottom end of the rotating plate 24 is hinged to the inner side of the sleeve frame 19 . The rotating plate 24 drives the sleeve 19 to move downward on the surface of the vertical rod 18, and the sleeve 19 moves downward on the inner side of the inner groove 10 by using the rotating rod 7. The bottom end of the rotating rod 7 drives the plate 23 to move downward, and the downwardly moving plate 23 drives the top of the rotating plate 24 to move downward. The rotating plate 24 rotates under the drive of the plate 23, and the rotating rotating plate 24 pushes the sleeve frame 19 to move downward on the surface of the vertical rod 18. The downwardly moving sleeve frame 19 cooperates to squeeze the first elastic sheet 20 on the top surface of the circular plate, and the downwardly moving sleeve frame 19 cooperates to pull the second elastic sheet 22. The two relative sleeve frames 19 move away from each other until the inner side wall of the sleeve frame 19 is in contact with the inner side surface of the vertical rod 18, and the distance between the two sleeve frames 19 reaches the maximum. The rotating rotating plate 24 drives the sleeve frame 19 to move vertically downward on the surface of the vertical rod 18, and the moving sleeve frame 19 continues to squeeze the first elastic sheet 20. At this time, the sleeve frame 19 is in a horizontal state, and the gear 9 moves down between the two tooth plates 14, and the gear 9 is meshed with the tooth plates 14.

[0031] The meshing of the gear 9 on the surface of the rotating rod 7 and the toothed plate 14 facilitates the fixing of the steel beam 2 on the side of the supporting steel 1 through the insertion rod 11. After the installation of the steel beam 2 is completed, the pressure applied to the turntable 8 is released, the second spring piece 22 pulls the sleeve 19 to move, and the first spring piece 20 pushes the sleeve 19 to move upward, the moving sleeve 19 uses the rotating plate 24 to push the flat plate 23 upward, and the upwardly moving flat plate 23 pushes the rotating rod 7 to move upward on the inner side of the T-shaped frame 5, and the upwardly moving rotating rod 7 drives the gear 9 to move upward on the inner side of the inner groove 10 until the gear 9 is separated from the toothed plate 14, and the gear 9 of the rotating rod 7 is separated from the toothed plate 14 by the elastic force of the first spring piece 20 and the second spring piece 22, so as to avoid the insertion rod 11 from moving inside the slot 12 due to touching the turntable 8, thereby ensuring the stability of the installation of the steel beam 2.

[0032] The overall shape of the sleeve 19 is set as a square frame, and the sleeve 19 is correspondingly sleeved on the surface of the square vertical rod 18 to prevent the sleeve 19 from rotating horizontally on the surface of the vertical rod 18. When the sleeve 19 moves up and down on the surface of the vertical rod 18, the limiting rod 21 inside the sleeve 19 moves up and down inside the vertical groove.

[0033] Working principle of the present invention:

[0034] Reference Figures 1 to 6 As shown, two folding plates 4 are relatively installed on the inner wall of the support steel 1 by bolts, and the T-frame 5 is placed between the two folding plates 4, and the bottom surfaces on both sides of the T-frame 5 are respectively attached to the top surfaces of the two folding plates 4, and the T-frame 5 is fixed inside the support steel 1 by multiple screws 6 to ensure the stability of the T-frame 5 inside the support steel 1.

[0035] The rotating plate 24 drives the sleeve 19 to move downward on the surface of the vertical rod 18, and the sleeve 19 moves downward on the inner side of the inner groove 10 by using the rotating rod 7. The bottom end of the rotating rod 7 drives the plate 23 to move downward, and the downwardly moving plate 23 drives the top of the rotating plate 24 to move downward. The rotating plate 24 rotates under the drive of the plate 23, and the rotating rotating plate 24 pushes the sleeve frame 19 to move downward on the surface of the vertical rod 18. The downwardly moving sleeve frame 19 cooperates to squeeze the first elastic sheet 20 on the top surface of the circular plate, and the downwardly moving sleeve frame 19 cooperates to pull the second elastic sheet 22. The two relative sleeve frames 19 move away from each other until the inner side wall of the sleeve frame 19 is in contact with the inner side surface of the vertical rod 18, and the distance between the two sleeve frames 19 reaches the maximum. The rotating rotating plate 24 drives the sleeve frame 19 to move vertically downward on the surface of the vertical rod 18, and the moving sleeve frame 19 continues to squeeze the first elastic sheet 20. At this time, the sleeve frame 19 is in a horizontal state, and the gear 9 moves down between the two tooth plates 14, and the gear 9 is meshed with the tooth plates 14.

[0036] Rotate the turntable 8, and the rotating turntable 8 drives the gear 9 to rotate by the rotating rod 7. The meshing effect of the rotating gear 9 and the tooth plate 14 makes the moving block 13 rotate inside the side groove. Since the two moving blocks 13 are relatively staggered, when the gear 9 rotates counterclockwise, the cooperation of the gear 9 and the tooth plate 14 makes the two moving blocks 13 move away from each other, and the moving block 13 squeezes the spring 16 on the surface of the inner rod 15 during the movement until the moving block 13 cannot move. Insert the inner end of the steel beam 2 into the side of the supporting steel 1 until the inner end of the steel beam 2 fits the folding plate 4. At this time, the bottom of the steel beam 2 is placed on the top surface of the cross plate 3 to limit the length of the steel beam 2 inserted into the supporting steel 1 through the folding plate 4, and the support of the cross plate 3 prevents the steel beam 2 from tilting. Release the torsion force applied to the rotating rod 7, and the elastic force of the spring 16 pushes the tooth plate 14 to move through the moving block 13. The tooth plates 14 moving towards each other make the gear 9 rotate clockwise until the insertion rod 11 is inserted into the slot 12.

[0037] After completing the installation of the steel beam 2, release the pressure applied to the turntable 8, the second spring piece 22 pulls the sleeve frame 19 to move, and the first spring piece 20 pushes the sleeve frame 19 to move upward, and the moving sleeve frame 19 uses the turn plate 24 to push the flat plate 23 to move upward, and the upwardly moved flat plate 23 pushes the rotating rod 7 to move upward on the inner side of the T-shaped frame 5, and the upwardly moved rotating rod 7 drives the gear 9 to move upward on the inner side of the inner groove 10 until the gear 9 is separated from the tooth plate 14, and the elastic force of the first spring piece 20 and the second spring piece 22 separates the gear 9 of the rotating rod 7 from the tooth plate 14, thereby avoiding the insertion rod 11 from moving inside the slot 12 due to touching the turntable 8, thereby ensuring the stability of the installation of the steel beam 2.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
