[0052] Here, it is ensured that the worm 5 can rotate normally in the threaded sleeve 13 and the first extrusion block 15 , and it is ensured that one end of the first extrusion block 15 can be extruded by the extrusion groove 14 .

[0053] Embodiment 4:

[0054] This embodiment provides an earthquake-resistant steel grid connection structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the extrusion assembly includes:

[0055] The second slide groove 16 is opened on the inner wall of the first slide groove 9 and is connected to the outside. A second extrusion block 17 is slidably connected in the second slide groove 16, and one side of the second extrusion block 17 is attached to the insert block 10. A threaded rod 18 is connected to the inner thread of the second extrusion block 17, and one end of the threaded rod 18 passes through the inner wall of the second slide groove 16 and extends to the outside to be rotatably connected to the splint 6.

[0056] Among them, when the user needs to replace the earthquake-resistant steel component 7, the user manually rotates the corresponding two threaded rods 18 to allow the two threaded rods 18 to rotate in the two second slide grooves 16 respectively. When the two threaded rods 18 rotate, the two second extrusion blocks 17 will be respectively moved upward by the action of the threads of the two threaded rods 18. When the two second extrusion blocks 17 move to the appropriate positions, the two second extrusion blocks 17 will release the extrusion of the two plug-in blocks 10, allowing one end of the two plug-in blocks 10 to be respectively affected by the elastic force of the corresponding two return springs 11 and enter the two first slide grooves 9 from the two slots 8 respectively. At this time, the fixation of the earthquake-resistant steel component 7 is released, and then the user can replace the earthquake-resistant steel component 7. After the replacement is completed, the user will replace it by hand. The seismic-resistant steel component 7 is then put back between the corresponding two clamps 6, and then the user manually rotates the corresponding two threaded rods 18 in opposite directions, so that the two threaded rods 18 rotate in opposite directions in the two second slide grooves 16 respectively. When the two reverse threaded rods 18 rotate, the two second extrusion blocks 17 will be respectively moved downward by the action of the threads of the two threaded rods 18. When the two second extrusion blocks 17 move downward, one end of the two second extrusion blocks 17 will respectively squeeze the two plug blocks 10, so that one end of the two plug blocks 10 is respectively inserted into the two slots 8 from the two first slide grooves 9, and the two plug blocks 10 respectively compress the corresponding two return springs 11, ensuring that the user can replace the seismic-resistant steel component 7 without moving the position of the corresponding two clamps 6.

[0062] It is ensured that when the bidirectional threaded rod 4 rotates, the two sliders 3 are moved closer to or farther away from each other by the action of the threads of the bidirectional threaded rod 4 .

[0063] When in use, the user places one end of the two earthquake-resistant steel components 7 between the corresponding two clamping plates 6 respectively, and then the user rotates the threaded sleeve 13 by hand, so that the threaded sleeve 13 is moved in the direction away from the first extrusion block 15 by the action of the thread of the thread groove 12. When the threaded sleeve 13 moves to a suitable position, one end of the first extrusion block 15 will disengage from the extrusion groove 14. At the same time, the extrusion groove 14 will release the extrusion on one end of the first extrusion block 15, allowing the first extrusion block 15 to release the extrusion on the worm 5, ensuring that the fixation of the worm 5 can be released. Then the user rotates the worm 5 by hand, so that the worm 5 drives the worm wheel 19 to rotate in the through groove 2, so that the worm wheel 19 drives the bidirectional threaded rod 4 to rotate in the through groove 2. When the bidirectional threaded rod 4 rotates, the two sliders 3 will be acted upon by the threads of the bidirectional threaded rod 4 to approach each other. When the two sliders 3 approach each other, the two sliders 3 will respectively drive multiple The clamping plate 6 moves toward the direction of the two earthquake-resistant steel components 7, and at the same time, the multiple clamping plates 6 will respectively drive one end of the multiple plug blocks 10 to move toward the direction of the two earthquake-resistant steel components 7. When the multiple clamping plates 6 move to the appropriate position, the multiple clamping plates 6 will respectively stick to the two earthquake-resistant steel components 7, and at the same time, one end of the multiple plug blocks 10 will be respectively inserted into the multiple slots 8. At this time, the two earthquake-resistant steel components 7 are connected to each other, ensuring that the earthquake-resistant steel components 7 of any thickness can be quickly fixed. Then the user manually rotates the threaded sleeve 13 in the opposite direction, so that the threaded sleeve 13 is moved toward the direction of the first extrusion block 15 by the action of the thread of the thread groove 12. When the threaded sleeve 13 moves to the appropriate position, the extrusion groove 14 will squeeze one end of the first extrusion block 15, so that the first extrusion block 15 squeezes the worm 5 to fix the worm 5, ensuring that the worm 5 can be fixed when it is rotated to the appropriate position.

[0064] When the user needs to replace the earthquake-resistant steel component 7, the user manually rotates the corresponding two threaded rods 18 to allow the two threaded rods 18 to rotate in the two second slide grooves 16 respectively. When the two threaded rods 18 rotate, the two second extrusion blocks 17 will be respectively moved upward by the action of the threads of the two threaded rods 18. When the two second extrusion blocks 17 move to the appropriate positions, the two second extrusion blocks 17 will release the extrusion of the two plug-in blocks 10, allowing one end of the two plug-in blocks 10 to be respectively affected by the elastic force of the corresponding two return springs 11 and enter the two first slide grooves 9 from the two slots 8 respectively. At this time, the fixation of the earthquake-resistant steel component 7 is released, and then the user can replace the earthquake-resistant steel component 7. After the replacement is completed, the user manually replaces the replaced one. The seismic-resistant steel component 7 is put back between the corresponding two clamps 6, and then the user rotates the corresponding two threaded rods 18 in reverse by hand, so that the two threaded rods 18 rotate in reverse in the two second slide grooves 16 respectively. When the two reverse threaded rods 18 rotate, the two second extrusion blocks 17 will be respectively moved downward by the action of the threads of the two threaded rods 18. When the two second extrusion blocks 17 move downward, one end of the two second extrusion blocks 17 will respectively squeeze the two plug blocks 10, so that one end of the two plug blocks 10 is respectively inserted into the two slots 8 from the two first slide grooves 9, and the two plug blocks 10 compress the corresponding two return springs 11 respectively, to ensure that the user can replace the seismic-resistant steel component 7 without moving the position of the corresponding two clamps 6.
