High-strength steel structure joint connection device and using method thereof

A high-strength steel structure joint connection device, comprising:

• a device body (9);
• a connection seat (2), disposed on two opposite side surfaces of the device body (9);
• an inner locking block (3), disposed inside the connection seat (2) and fixedly connected to one of the side surfaces of the device body (9);
• and
• a steel structure body (4), inserted between the connection seat (2) and the inner locking block (3), wherein the steel structure body (4) and the connection seat (2) are detachably and fixedly connected through a positioning mechanism;
• wherein the positioning mechanism comprises:
• a threaded hole (1), defined on a side surface of the connection seat (2) adjacent to the device body (9);
• a fixing bolt (14), screwed into the threaded hole (1);
• wherein the threaded hole (1) sequentially penetrates through side walls of the steel structure body (4) and the inner locking block (3) in a direction perpendicular to the side surface of the connection seat (2);
• and
• a rotating plate (12), disposed on an outer end of the fixing bolt (14);
• wherein the rotating plate (12) is configured to drive the fixing bolt (14) to rotate;
• wherein the fixing bolt (14) is provided with a threaded cylinder (18) therein, the threaded cylinder (18) is arranged along an axial direction of the fixing bolt (14), a push rod (8) is screwed into the threaded cylinder (18), a side wall of an inner end of the fixing bolt (14) defines a sliding groove (17), a sliding block (19) is disposed in the sliding groove (17), an inner end of the sliding block (19) is movably connected to the sliding groove (17), each of contact surfaces of the push rod (8) and the sliding block (19) is provided with an inclined surface (22), and when the push rod (8) is screwed inward, the push rod (8) pushes a free end of the sliding block (19) out of the sliding groove (17);
• wherein the sliding groove (17) is provided with an accommodation groove (16), a side surface of the inner end of the sliding block (19) is fixedly connected to a connection plate (21), the connection plate (21) is movably connected to the accommodation groove (16), a side surface of the connection plate (21) is fixedly connected to an end of a return spring (20), and another end of the return spring (20) is fixedly connected to an inner surface of the accommodation groove (16), and when the push rod (8) is unscrewed outward, the return spring (20) pulls the sliding block (19) back to reset;
• and
• wherein the rotating plate (12) is threadedly connected to a sleeve (13), an inner surface of the sleeve (13) is fixedly connected to a buffer spring (10) and a damper (11), the damper (11) is disposed inside the buffer spring (10), and the damper (11) and the buffer spring (10) cooperate to push the sleeve (13) against the connection seat (2) to absorb vibration and impact, and to relatively fix the fixing bolt (14) and the threaded hole (1) through a reaction force.
