DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-10 The present invention provides a technical solution: a steel structure bracket that is easy to store, including a longitudinal rod A1, two longitudinal rods A1 are provided, one end of the longitudinal rod A1 is rotatably connected to the longitudinal rod B11, a plurality of limit grooves 12 are provided on the tops of the longitudinal rods A1 and the longitudinal rods B11, a plurality of cross rods 2 are provided between the two longitudinal rods A1 and between the longitudinal rods B11, and both ends of the cross rods 2 are fixedly connected to limit rings 3.

[0034] Furthermore, when carrying out construction work, according to specific needs, the limiting rings 3 at both ends of the cross bar 2 are mounted on the longitudinal bar A1 from the end of the longitudinal bar A1 away from the longitudinal bar B11. At this time, the assembly of the longitudinal bar A1 and the cross bar 2 can be completed. After that, the cross bar 2 is held and the position of the cross bar 2 is moved so that part of the cross bar 2 is moved between the longitudinal bars B11 through the limiting rings 3, and the intervals between each cross bar 2 are adjusted so that it can better support the building-related structures.

[0035] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 7 and Fig. 9 As shown, two mounting grooves 21 are provided on one side of the cross bar 2, and fixing springs 22 are fixedly connected on the inner walls of the mounting grooves 21, and a magnet plate 23 is fixedly connected to one end of the fixing spring 22 close to the opening of the mounting groove 21, and a rubber pad 24 is fixedly connected to the side of the magnet plate 23 away from the fixing spring 22, and two plug rods 25 are fixedly connected to the side of the cross bar 2 away from the mounting groove 21, and the plug rod 25 is made of metal material and is separated between the magnet plate 23 and the plug rod 25 on another cross bar 2 by the rubber pad 24. When the plug rod 25 contacts the magnet plate 23, the magnet plate 23 is protected to prevent the plug rod 25 from being damaged by excessive impact force when it is inserted into the mounting groove 21 on the other cross bar 2, and at the same time, the rubber pad 24 is used for blocking, which can reduce the adsorption force of the magnet plate 23 on the plug rod 25, so that it is convenient for the staff to manually separate the cross bar 2 later;

[0036] The limiting rings 3 are sleeved on the longitudinal rods A1 and B11 on the same side thereof, and are slidably connected to the longitudinal rod A1. The limiting rings 3 are also slidably connected to the longitudinal rod B11. The top of the limiting ring 3 is threadedly connected to a screw A32, and the bottom end of the screw A32 is located in a limiting groove 12 at a corresponding position thereto. The top of the screw A32 is fixedly connected to a knob 33. A positioning hole 34 is provided on the side of the limiting ring 3 away from the cross bar 2. The sides of the longitudinal rods A1 and B11 away from the cross bar 2 are provided with scale grooves 13 corresponding to the number and position of the limit grooves 12, and the scale grooves 13 are the same size as the positioning holes 34 on the limiting ring 3.

[0037] Furthermore, when the cross bar 2 is stored, the insertion rod 25 on the cross bar 2 will be inserted into the installation groove 21 on the cross bar 2 on the adjacent side. When the insertion rod 25 is inserted into the installation groove 21, the insertion rod 25 will be against the rubber pad 24. At this time, the fixing spring 22 can buffer the impact force generated when the insertion rod 25 contacts the rubber pad 24. At the same time, when the insertion rod 25 is in contact with the rubber pad 24, the magnet plate 23 will adsorb the insertion rod 25 through the rubber pad 24, so that the cross bars 2 are fixed and limited to each other, preventing the cross bars 2 from being easily separated from each other due to external force after being stored. At the same time, since the insertion rod 25 has a certain length, after the cross bars 2 are stored together, the length of the insertion rod 25 can be used to leave a certain gap between the cross bars 2, so as to prevent the cross bars 2 from easily clamping the operator's hand during the storage process.

[0038] When the positioning hole 34 moves to the position of the scale groove 13, it means that the screw A32 is located directly above the limiting groove 12. At this time, the knob 33 is manually turned to drive the screw A32 to rotate so that the screw A32 is inserted into the limiting groove 12. At this time, the limiting ring 3 can be limited and fixed, so that the cross bar 2 is fixed. At this time, the longitudinal rod A1, the longitudinal rod B11 and the cross bar 2 can cooperate with each other to complete the support work of the building structure. When the steel structure bracket is used up, the knob 33 is rotated in the opposite direction to drive the screw A32 to rotate in the opposite direction. The screw A32 will be pulled out of the limiting groove 12 during the reverse rotation. At this time, the limiting work of the limiting ring 3 can be released. At this time, the longitudinal rod A1 is erected. At this time, the cross bar 2 will all slide to the bottom end of the longitudinal rod A1 due to gravity and stacked together, which is convenient for subsequent storage work.

[0039] Combined with Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10As shown, a mounting ring A4 is fixedly connected to one end of the bottom of the longitudinal rod B11 near the longitudinal rod A1, a mounting ring B41 is fixedly connected to one end of the bottom of the longitudinal rod A1 near the longitudinal rod B11, a limiting rod A42 is slidably connected between the mounting ring A4 and the mounting ring B41, an operating rod 43 is fixedly connected to one side of the limiting rod A42, a notch for accommodating the operating rod 43 is provided on one side of the mounting ring A4, a connecting port 31 is provided at the bottom of the limiting ring 3, and the width of the connecting port 31 is greater than the width of the mounting ring A4 and the mounting ring B41. Through the design of the connecting port 31 at the bottom of the limiting ring 3, the limiting ring 3 will not be hindered by the mounting ring A4, the mounting ring B41 and the fixing seat 5 when moving on the longitudinal rod A1 and the longitudinal rod B11, and the fixing seat 5 is fixedly connected to the bottom of the longitudinal rod A1. 5. A fixing groove 51 is provided on one side of the fixing seat 5 close to the mounting ring B41, and a shaft rod 52 is rotatably connected in the fixing groove 51. Both ends of the shaft rod 52 are rotatably connected to the staggered mounting plates A53 and mounting plates B531. A fixing rod A54 is fixedly connected between one end of the mounting plate A53 close to the mounting ring B41, and a fixing rod B541 is fixedly connected between one end of the mounting plate B531 close to the mounting ring B41. One end of the limiting rod A42 close to the fixing seat 5 is fixedly connected to the limiting rod B7. The top and bottom of the limiting rod B7 close to one end of the fixing seat 5 are fixedly connected to the limiting block 71. The limiting block 71 is provided with an inclined surface on one side of the fixing seat 5. A limiting spring 72 is fixedly connected between the fixing seat 5 and the limiting rod A42, and the limiting spring 72 is sleeved outside the limit rod B7, a connecting rod A55 is fixedly connected between one end of the mounting plate A53 away from the mounting ring B41, and a connecting rod B551 is fixedly connected between one end of the mounting plate B531 away from the mounting ring B41, mounting holes 56 are opened on the mounting plate A53 and the mounting plate B531, and the mounting plate A53 and the mounting plate B531 are rotatably sleeved on the shaft rod 52 through the mounting holes 56, and a torsion spring 57 is fixedly connected between the inner wall of the mounting hole 56 and the shaft rod 52. Through the design of the torsion spring 57, the torsion spring 57 can be tightened when the mounting plate A53 and the mounting plate B531 rotate, and when the external force on the mounting plate A53 and the mounting plate B531 disappears, the rebound characteristics of the torsion spring 57 are utilized to make the mounting plate A53 and the mounting plate B531 B531 rotates back to its original position, an extrusion block 6 is arranged in the fixed groove 51, and the extrusion block 6 is located between the connecting rod A55 and the connecting rod B551, and an inclined surface is arranged on the side of the extrusion block 6 close to the connecting rod A55 and the connecting rod B551, through which an inclined thrust can be applied to the connecting rod A55 and the connecting rod B551 when the extrusion block 6 moves toward the connecting rod A55 and the connecting rod B551, so as to better separate the connecting rod A55 and the connecting rod B551, and rotate the mounting plate A53 and the mounting plate B531, and a pressing plate 61 is arranged on the outside of the fixing seat 5 away from the mounting ring B41, and a support rod is fixedly connected between the extrusion block 6 and the pressing plate 61, and the support rod between the extrusion block 6 and the pressing plate 61 passes through the fixing seat 5,And it is slidably connected with the fixing seat 5.

[0040] Furthermore, after the cross bar 2 is stored, the joystick 43 is held, and the joystick 43 is used to drive the limit rod A42 to move, so that the end of the limit rod A42 close to the joystick 43 moves out of the mounting ring A4, and in this process, the limit rod A42 will drive the limit rod B7 to move toward the fixing groove 51, and drive the limit spring 72 to squeeze and contract. When the limit rod B7 enters the fixing groove 51, the limit block 71 on the limit rod B7 will contact the fixing rod A54 and the fixing rod B541. Since the limit blocks 71 are all provided with inclined surfaces, the limit blocks 71 can be moved by Its inclined surface applies an inclined thrust to the fixing rod A54 and the fixing rod B541, and the mounting plate A53 and the mounting plate B531 are rotated by the thrust, so that the fixing rod A54 and the fixing rod B541 are separated. When the mounting plate A53 and the mounting plate B531 rotate, they can drive the torsion spring 57 to tighten through the inner wall of the mounting hole 56. When the limit block 71 moves to the other side of the fixing rod A54 and the fixing rod B541, the thrust on the fixing rod A54 and the fixing rod B541 disappears, so the torsion spring 57 starts to rebound, and the torsion spring 57 can drive the mounting plate A53 and the mounting plate B531 to rotate in the opposite direction. , so that the fixing rod A54 and the fixing rod B541 respectively limit and fix the limit blocks 71 on both sides of the top and bottom of the limit rod B7, and then the longitudinal rod B11 can be rotated to fold it on one side of the longitudinal rod A1 on the same side, further improving the auxiliary function of storing the steel structure bracket. When the steel structure bracket needs to be used, the longitudinal rod B11 is first rotated to form a horizontal straight line state with the longitudinal rod A1 connected to the longitudinal rod B11. At this time, the pressing plate 61 is manually squeezed, and the pressing plate 61 is used to drive the squeezing block 6 to squeeze the connecting rod A55 and the connecting rod B551, so that the connecting rod A55 and the connecting rod B551 are separated from each other. When the mounting plates A53 and B531 rotate, the connecting rod A55 and the connecting rod B551 will drive the mounting plates A53 and B531 to rotate. When the mounting plates A53 and B531 rotate, the fixing rods A54 and B541 at the other ends thereof can be separated from each other. At this time, the limiting force exerted on the limiting block 71 disappears, and the limiting spring 72 will begin to rebound and push the limiting rod A42 to move, so that one end of the limiting rod A42 is inserted into the mounting ring A4. At this time, the limiting and fixing work of the longitudinal rods A1 and B11 can be completed through the cooperation of the mounting ring A4, the mounting ring B41 and the limiting rod A42, and then the position of the cross bar 2 can be adjusted.

[0041] Combined with Figure 1 and Figure 8As shown, one end of the longitudinal rod A1 away from the longitudinal rod B11 is threadedly connected with a screw B81, and the other end of the screw B81 away from the longitudinal rod A1 is fixedly connected with a baffle plate 8, and the baffle plate 8 is rotatably connected with a limit plate 82. The limit plate 82 has two slide grooves 83 on the side close to the longitudinal rod A1, and the slide grooves 83 are slidably connected with limit frames 84. An installation spring 85 is fixedly connected between the limit frame 84 and the inner wall of the slide groove 83 on the same side, and a connecting plate 86 is fixedly connected between the two limit frames 84.

[0042] Further, when increasing or decreasing the number of cross bars 2 or repairing or replacing the cross bars 2, the baffle plate 8 is rotated, and the baffle plate 8 is used to drive the screw B81 to rotate, so that the baffle plate 8 is disassembled. At this time, the limit ring 3 can be sleeved on the longitudinal rod A1, so as to increase the cross bars 2. After increasing or decreasing the cross bars 2 or repairing or replacing, the baffle plate 8 is reinstalled on the longitudinal rod A1 by the screw B81, and the limit ring 3 can be limited and blocked to prevent the limit ring 3 from falling off the longitudinal rod A1. After the longitudinal rod B11 is folded, the end of the longitudinal rod B11 that was originally away from the longitudinal rod A1 is fitted together with the end of the longitudinal rod A1 that was originally away from the longitudinal rod B11. At this time, the limit frame 84 is pulled by the connecting plate 86, and the installation spring 85 is pulled by the limit frame 84 to stretch it. Then, the limit plate 82 is rotated to drive the limit frame 84 to rotate to one side of the longitudinal rod B11, and then the connecting plate 86 is loosened. At this time, the installation spring 85 begins to rebound, driving the limit frame 84 to fit on the longitudinal rod B11. At this time, the limit frame 84 can complete the limiting work of the longitudinal rod B11 to prevent the longitudinal rod B11 from being separated from the longitudinal rod A1 by external force. When the steel structure bracket needs to be used, the limit frame 84 is pulled again through the connecting plate 86 to separate the limit frame 84 from the longitudinal rod B11, and then the limit plate 82 is rotated to drive the limit frame 84 to move away from one side of the longitudinal rod B11. At this time, the longitudinal rod B11 loses the limiting effect of the limit frame 84, and the longitudinal rod B11 can be manually rotated to allow the longitudinal rod A1 and the longitudinal rod B11 to be unfolded and used.

[0043] Working principle: First, rotate the baffle plate 8, and use the baffle plate 8 to drive the screw rod B81 to rotate, so as to disassemble the baffle plate 8. At this time, according to specific needs, the limiting rings 3 at both ends of the cross bar 2 are sleeved on the longitudinal bar A1 from the end of the longitudinal bar A1 away from the longitudinal bar B11. At this time, the assembly of the longitudinal bar A1 and the cross bar 2 can be completed. Then, hold the cross bar 2, move the position of the cross bar 2, adjust the interval between each cross bar 2, and then reinstall the baffle plate 8 on the longitudinal bar A1 using the screw rod B81, so as to limit and block the limiting ring 3;

[0044] In the process of manually moving the cross bar 2, the position of the cross bar 2 is positioned through the positioning hole 34 on the limiting ring 3. When the positioning hole 34 moves to the position of the scale groove 13, it means that the screw rod A32 is located directly above the limiting groove 12. At this time, the knob 33 is manually turned to drive the screw rod A32 to rotate, so that the screw rod A32 is inserted into the limiting groove 12. At this time, the limiting ring 3 can be limited and fixed, so that the cross bar 2 is fixed. At this time, the longitudinal rod A1, the longitudinal rod B11 and the cross bar 2 can cooperate with each other to complete the support work of the building structure;

[0045] After the use of the steel structure bracket is completed, the knob 33 is rotated in the reverse direction to drive the screw rod A32 to rotate in the reverse direction. The screw rod A32 will be pulled out of the limit groove 12 during the reverse rotation. At this time, the limit ring 3 can be released. At this time, the longitudinal rod A1 is erected. At this time, the cross rod 2 will all slide down to the bottom end of the longitudinal rod A1 due to gravity and stacked together, which is convenient for subsequent storage. When the cross rod 2 is stored, the insertion rod 25 on the cross rod 2 will be inserted into the installation groove 21 on the cross rod 2 on the adjacent side. When the insertion rod 25 is inserted into the installation groove 2 1, the plug rod 25 will be against the rubber pad 24, and at this time, the fixing spring 22 can buffer the impact force generated when the plug rod 25 contacts the rubber pad 24. At the same time, when the plug rod 25 is in contact with the rubber pad 24, the magnet plate 23 will absorb the plug rod 25 through the rubber pad 24, so that the cross bars 2 are fixed and limited to each other, preventing the cross bars 2 from being easily separated from each other due to external forces after being stored. At the same time, since the plug rod 25 has a certain length, after the cross bars 2 are stored together, the length of the plug rod 25 can be used to leave a certain gap between the cross bars 2;

[0046] After the cross bar 2 is stored, the joystick 43 is held, and the joystick 43 drives the limit rod A42 to move, so that the end of the limit rod A42 close to the joystick 43 moves out of the mounting ring A4, and in this process, the limit rod A42 drives the limit rod B7 to move toward the fixing groove 51, and drives the limit spring 72 to squeeze and contract. When the limit rod B7 enters the fixing groove 51, the limit block 71 on the limit rod B7 contacts the fixing rod A54 and the fixing rod B541, and because the limit block 7 1 are provided with inclined surfaces, so when the limit block 71 moves with the limit rod B7, it can apply an inclined thrust to the fixing rod A54 and the fixing rod B541 through its inclined surface, and use this thrust to rotate the mounting plate A53 and the mounting plate B531 to separate the fixing rod A54 and the fixing rod B541. When the mounting plate A53 and the mounting plate B531 rotate, they can drive the torsion spring 57 to tighten through the inner wall of the mounting hole 56. When the limit block 71 moves to the fixing rod A54 and the fixing rod When the fixing rod A54 and the fixing rod B541 are moved to the other side, the thrust on the fixing rod A54 and the fixing rod B541 disappears, so the torsion spring 57 starts to rebound. At this time, the torsion spring 57 can drive the mounting plate A53 and the mounting plate B531 to rotate in the opposite direction, so that the fixing rod A54 and the fixing rod B541 respectively limit and fix the limit blocks 71 on the top and bottom sides of the limit rod B7, and then the longitudinal rod B11 can be rotated to fold on the side of the longitudinal rod A1 on the same side. At this time, the end of the longitudinal rod B11 that was originally away from the longitudinal rod A1 is aligned with the longitudinal rod A1. The ends originally away from the longitudinal rod B11 are fitted together, and the limiting frame 84 is pulled by the connecting plate 86, and the installation spring 85 is pulled by the limiting frame 84 to stretch it, and then the limiting plate 82 is rotated to drive the limiting frame 84 to rotate to one side of the longitudinal rod B11, and then the connecting plate 86 is loosened, and the installation spring 85 starts to rebound, driving the limiting frame 84 to fit on the longitudinal rod B11. At this time, the limiting work of the longitudinal rod B11 can be completed by the limiting frame 84, and the storage work of the entire steel structure bracket can be completed at this time;

[0047] When the steel structure bracket needs to be used again, the limit frame 84 is pulled again through the connecting plate 86 to separate the limit frame 84 from the longitudinal rod B11, and then the limit plate 82 is rotated to drive the limit frame 84 to move away from one side of the longitudinal rod B11. At this time, the longitudinal rod B11 loses the limiting effect of the limit frame 84, and the longitudinal rod B11 can be manually rotated to unfold the longitudinal rod A1 and the longitudinal rod B11 for use. First, the longitudinal rod B11 is rotated to form a horizontal straight line with the longitudinal rod A1 connected to the longitudinal rod B11. At this time, the pressing plate 61 is manually squeezed, and the pressing plate 61 is used to drive the squeezing block 6 to squeeze the connecting rod A55 and the connecting rod B551, so that the connecting rod A55 and the connecting rod B551 are separated from each other. At this time Connecting rod A55 and connecting rod B551 will drive mounting plate A53 and mounting plate B531 to rotate. When mounting plate A53 and mounting plate B531 rotate, fixing rod A54 and fixing rod B541 at the other end thereof can be separated from each other. At this time, the limiting force on limiting block 71 disappears, and limiting spring 72 will start to rebound and push limiting rod A42 to move, so that one end of limiting rod A42 is inserted into mounting ring A4. At this time, the limiting and fixing work of longitudinal rod A1 and longitudinal rod B11 can be completed through the cooperation of mounting ring A4, mounting ring B41 and limiting rod A42. After that, the position of cross bar 2 can be adjusted, and the steel structure bracket can continue to be used to support the building structure.
