DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1 - Figure 4 The utility model provides a technical solution: a rod docking structure of a steel structure grid, comprising a connecting ball 1, a connecting groove 2, a rod body 3, a thermal expansion and contraction ring 4, a reinforcement component 5, a steel structure block 6 and a steel structure plate 7. A plurality of connecting grooves 2 are provided at the outer end of the connecting ball 1, and a rod body 3 is movably connected inside each connecting groove 2, and a thermal expansion and contraction ring 4 is fixedly installed inside each connecting groove 2. The thermal expansion and contraction ring 4 changes with the temperature because the movement of particles (atoms) in an object changes with temperature. When the temperature rises, the vibration amplitude of the particles increases, causing the object to expand, but when the temperature drops, the vibration amplitude of the particles decreases, causing the object to shrink. A connecting rod 11 is fixedly installed inside each connecting groove 2, and reinforcement components 5 are symmetrically arranged on both sides of each connecting rod 11. A steel structure block 6 is fixedly installed on the top of the connecting ball 1, and a steel structure plate 7 is fixedly installed on the top of the steel structure block 6. The material of the steel structure plate 7 and the steel structure block 6 are both steel.

[0022] Furthermore, a plurality of first expansion bolts 8 are fixedly installed at the bottom of the steel structure plate 7 , a steel structure connection block 9 is movably connected inside the steel structure block 6 , and an anti-loosening component 10 is provided on one side of the steel structure connection block 9 .

[0023] Furthermore, the reinforcement component 5 includes grooves 51, and every two grooves 51 are symmetrically opened on both sides of the connecting rod 11, and a first magnet 52 is fixedly installed inside each groove 51, and a spring 53 is symmetrically fixedly installed inside the groove 51. The spring 53 is elastic and plays a resetting role.

[0024] Furthermore, a clamping plate 54 is fixedly installed at one end of each spring 53, and a slot 55 is provided at the outer end of each clamping plate 54. The sizes of the clamping plate 54 and the slot 55 are adapted. The slot 55 is opened inside the rod body 3. A second magnet 56 is fixedly installed on one side of each clamping plate 54. The magnetic poles of the first magnet 52 and the second magnet 56 are the same and have mutual repulsion.

[0025] Furthermore, the anti-loosening component 10 includes a fixing groove 101, which is opened inside the steel structure connecting block 9. A through groove 102 is opened on one side of the steel structure block 6. A fixing block 103 is movably connected inside the through groove 102. The sizes of the fixing groove 101 and the fixing block 103 are adapted.

[0026] Furthermore, a limiting plate 104 is fixedly installed at one end of the fixing block 103, and the limiting plate 104 is located on one side of the steel structure block 6. A second expansion bolt 105 is symmetrically fixedly installed on one side of the limiting plate 104. The threads of the first expansion bolt 8 and the second expansion bolt 105 bolts and nuts cooperate with each other. By tightening the nuts, the bolts are moved outward, and the metal sleeve does not move, thereby generating pressure in the hole, causing the expansion tube to open and fill the hole, forming a friction self-locking effect.

[0027] To sum up: the staff places the steel structure plate 7 at the workplace, fixes the connecting ball 1 with multiple first expansion bolts 8, then inserts the fixing block 103 through the steel structure block 6 into the inside of the fixing groove 101, fixes the limit plate 104 with two second expansion bolts 105, reinforces and fixes the connecting ball 1, then inserts the rod body 3 to be connected into the inside of the connecting groove 2 inside the connecting ball 1, pushes the rod body 3, presses the clamping plate 54 into the inside of the groove 51, connects the clamping plate 54 with the spring 53, and when the clamping plate 54 and the card slot 55 are overlapped, the clamping plate 54 is stuck in the inside of the card slot 55 by the repulsive force of the first magnet 52 and the second magnet 56, fixes the rod body 3, and finally cools the thermal expansion and contraction circle 4, shrinks the inside of the connecting groove 2, and reinforces the connection of the rod body 3, making the docking structure more stable.
