[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1 - Figure 4 The seismic-resistant frame joint structure shown is applied at the connection between column 1 and crossbar 2, including: The first connecting block 3 is fixedly connected to one side of the column 1; The second connecting block 4 is fixedly connected to one side of the crossbar 2; The limiting block 5 has a limiting groove 501 in the middle, and the first connecting block 3 and the second connecting block 4 are both inserted into the inside of the limiting groove 501. Limiting component 6 is disposed at the connection between the first connecting block 3 and the limiting block 5; The fixing component 7 is disposed at the connection between the limiting block 5 and the first connecting block 3 and the second connecting block 4. The fixing component 7 is used to fix the limiting block 5 to the first connecting block 3 and the second connecting block 4.

[0019] It should be noted that the limiting groove 501 is I-shaped and is adapted to the first connecting block 3 and the second connecting block 4, so that the limiting block 5 can be fitted onto the first connecting block 3 and the second connecting block 4 through the limiting groove 501. The first connecting block 3 is fixedly connected to one side of the column 1 by pre-embedding, and the second connecting block 4 is fixedly connected to the end of the crossbar 2 by pre-embedding. In use, the limiting block 5 is first fitted onto the first connecting block 3 and the limiting component 6 is used to limit the limiting block 5 onto the first connecting block 3. When it is necessary to fix the crossbar 2, the second connecting block 4 is aligned with the first connecting block 3, and then the position of the limiting block 5 is moved so that the limiting block 5 is fitted onto the second connecting block 4. The limiting block 5 limits the second connecting block 4 and prevents misalignment between the second connecting block 4 and the first connecting block 3 during use.

[0020] Specifically, the limiting component 6 includes a groove 601 formed in the middle of the first connecting block 3. A threaded rod 604 is inserted into the groove 601. A connector is provided at the connection between the threaded rod 604 and the limiting block 5. The connector includes a first mounting block 602 fixedly connected to one end of the threaded rod 604. A second mounting block 606 is provided on the back of the limiting block 5. A threaded groove 605 is formed on the front of the second mounting block 606. The threaded rod 604 is threadedly inserted into the inside of the threaded groove 605. Both the front and back inner walls of the limiting groove 501 have through holes 603. The threaded rod 604 is inserted into the inside of the through holes 603. A rotating groove is formed on the opposite side of the first mounting block 602 and the second mounting block 606. The rotating groove is used to rotate a tool to insert into the first mounting block 602 and the second mounting block 606.

[0021] It should be noted that the cross-section of the rotating groove is set to hexagonal, slotted, or cross-shaped. When in use, a screwdriver is inserted and connected to one side of the first mounting block 602 and the second mounting block 606. When in use, the first mounting block 602 and the second mounting block 606 are rotated by the screwdriver. At the same time, the rotation of the first mounting block 602 and the second mounting block 606 can be restricted by the screwdriver.

[0022] Furthermore, when it is necessary to connect the limiting block 5 to the first connecting block 3, the limiting block 5 is first fitted onto the first connecting block 3. After the through hole 603 is aligned with the slide groove 601, the threaded rod 604 is passed through the through hole 603 and the slide groove 601, so that the first mounting block 602 fits against the front of the limiting block 5. Then, the second mounting block 606 is threaded onto one end of the threaded rod 604, so that the second mounting block 606 fits against the back of the limiting block 5. When the limiting block 5 moves, it drives the threaded rod 604 to move. When the threaded rod 604 moves to fit against the inner wall of the slide groove 601, the slide groove 601 blocks the threaded rod 604 from moving, and the movement distance of the limiting block 5 is limited by the threaded rod 604 that restricts its movement.

[0023] Specifically, the fixing component 7 includes a mounting bolt 705 located at the connection between the second connecting block 4 and the limiting block 5. The mounting bolt 705 has a first nut 701 and a second nut 702 threadedly connected to its middle part. The inner walls of the top and bottom ends of the limiting groove 501 are provided with first fixing holes 703. The top and bottom of the first connecting block 3 and the second connecting block 4 are provided with second fixing holes 704. The mounting bolt 705 is inserted into the interior of the first fixing holes 703 and the second fixing holes 704.

[0024] Furthermore, when it is necessary to fix the first connecting block 3, the second connecting block 4, and the limiting block 5 together, the second fixing holes 704 on the first connecting block 3 and the second connecting block 4 are aligned with the first fixing holes 703 on the limiting block 5. Then, the mounting bolts 705 are passed through the limiting block 5 and the first connecting block 3 or the second connecting block 4 in sequence. Finally, the first nut 701 and the second nut 702 are threaded onto the mounting bolts 705. In this way, the limiting block 5 and the first connecting block 3 and the second connecting block 4 are fixed. By tightening the two nuts together, a preload interlock is formed, which effectively resists vibration and load changes and prevents the bolts from loosening.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
