[0021] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] An earthquake-resistant steel structure connector and a steel structure according to a preferred embodiment of the present invention will be described in detail below.

[0023] Embodiment 1, as Figure 1-Figure 9 As shown, it comprises a support beam 1, a connecting member 2 is arranged on the surface of the support beam 1, and a locking mechanism 3 and a fixing mechanism 4 are arranged on the surface of the connecting member 2; The locking mechanism 3 includes a connecting block 301 fixedly mounted on the surface of the connecting member 2, a crossbeam 5 is arranged on one side of the connecting block 301, a locking mechanism 6 is arranged inside the connecting block 301, a rotating groove 302 is opened on the surface of the connecting block 301, and two groups of rotating grooves 302 are symmetrically arranged, a rotating member 303 is fixedly mounted on the top of the connecting block 301, and two groups of rotating members 303 are symmetrically arranged, and a locking rod 304 is rotatably connected to the rotating member 303 through a torsion spring; The locking mechanism 6 includes a moving groove 61 provided inside the connecting block 301, and the moving groove 61 is symmetrically arranged in two groups. The connecting block 301 is slidably mounted with a locking plate 62 through the moving groove 61, and a first wedge block 63 is fixedly mounted on a surface opposite to the locking plate 62, and a second wedge block 64 is slidably mounted on a surface opposite to the side of the cross beam 5. A locking groove 65 is provided on one side of the cross beam 5, and the locking groove 65 is symmetrically arranged in two groups. The fixing mechanism 4 is used to fix the locking rod 304; The staff first installs the connecting piece 2 on the surface of the supporting beam 1, then manually rotates the locking rod 304 through the rotating piece 303, and then inserts the crossbeam 5 into the connecting block 301. When the crossbeam 5 is installed inside the connecting block 301, the second wedge block 64 on the surface of the crossbeam 5 contacts the first wedge block 63 on the surface of the locking plate 62 when moving, and drives the locking plate 62 to move through the first wedge block 63. When the locking groove 65 on the surface of the crossbeam 5 coincides with the moving groove 61 on the surface of the connecting block 301, the locking rod 304 is released, and the locking rod 304 is The torsion spring is reset, so that the locking groove 65 is engaged and fixed with the cross beam 5, and then the locking rod 304 can be fixed by the fixing mechanism 4. When an earthquake occurs, the support beam 1 will vibrate and shake due to the earthquake, and the cross beam 5 will collide with the connecting block 301 when it contacts with it. At this time, the second wedge block 64 contracts, and the first wedge block 63 on the surface of the locking plate 62 will drive the locking plate 62 to move and reset due to the loss of the obstruction of the second wedge block 64. At this time, the locking plate 62 will seal the rotating groove 302, and the locking rod 304 will be blocked by the locking plate 62 and cannot rotate. By setting up the locking mechanism 3, the common bolt connection method can be changed to a snap-on connection. There is no need for precise docking of the bolt holes, and there is no need for too many tools for tightening. The installation is simpler and faster, which improves the construction efficiency. By using the set locking mechanism 6, when an earthquake occurs and the support beam 1 shakes, it can be reset through the locking plate 62 to limit the rotation of the locking rod 304, which can prevent the locking rod 304 from loosening or dislocating under the action of vibration loads such as earthquakes, thereby ensuring the stability and integrity of the structure, thereby improving the overall seismic performance.

[0024] Embodiment 2, as Figure 1-Figure 7 As shown, a matching block 305 is fixedly installed on the top of the locking rod 304, and a locking groove 306 is opened on the opposite side of the matching block 305. The top of the matching block 305 is arranged in an arc shape. The fixing mechanism 4 includes a fixing block 401 arranged above the connecting block 301, and a fixing plate 402 is arranged inside the fixing block 401. A fixing piece 403 is fixedly installed on one side of the fixing plate 402. The fixing piece 403 is symmetrically arranged in two groups, and the fixing piece 403 matches the locking groove 306. When the fixing block 401 moves downward, the fixing plate 402 contacts the matching block 305 at the top of the locking rod 304 during the continuous downward movement, and the fixing plate 402 pushes the matching block 305 to rotate outward through the rotating member 303 until the fixing member 403 on the surface of the fixing plate 402 engages with the locking groove 306, and the fixing block 401 blocks the matching block 305 to prevent it from rotating. The fixing member 403 and the locking groove 306 can limit the locking rod 304 to prevent the locking rod 304 from shifting and disengaging from the fixing member 403 when shaking occurs, thereby improving the stability after installation.

[0025] Embodiment three, as Figure 1-Figure 9 As shown, a matching groove 7 is provided inside the connector 2, and two groups of matching grooves 7 are symmetrically arranged. A matching rod 8 is slidably installed inside the matching groove 7, and a matching spring 9 is sleeved on the surface of the matching rod 8. One end of the matching rod 8 is fixedly connected to the locking plate 62. A fixing frame 404 is provided inside the fixing block 401, and the fixing frame 404 is slidably connected to the inner wall of the fixing block 401. The fixing plate 402 is fixedly connected to the inner wall of the fixing frame 404. An extension rod 405 is fixedly installed on the top of the fixing frame 404, and an energy storage spring 406 is sleeved on the surface of the extension rod 405. The extension rod 405 penetrates and extends to the top of the fixing block 401. A replacement rod 407 is fixedly installed on the bottom of the fixing plate 402. A groove matching the replacement rod 407 is provided on the top of the crossbeam 5 and the connecting block 301. When the fixing mechanism 4 installs the locking rod 304 and the fixing block 401 continues to move downward, the matching block 305 will first contact the fixing plate 402, and at the same time, the matching block 305 will push the fixing plate 402 to drive the fixing frame 404 to slide upward inside the fixing block 401. At the same time, during the sliding process, the fixing frame 404 will continue to squeeze the energy storage spring 406, and the energy storage spring 406 will shrink due to elastic potential energy. When the locking rod 304 is broken due to an earthquake, the fixing plate 402 loses its blocking force, and the energy storage spring 406 will push the fixing plate 402 down due to the force of the elastic potential energy, so that the replacement rod 407 at the bottom of the fixing plate 402 is inserted into the groove opened at the top of the crossbeam 5, thereby playing a role of replacement. By setting up the fixing mechanism 4, when the locking rod 304 breaks due to excessive stress, it can immediately play a role when the original locking rod 304 fails, ensuring that the beam 5 is still connected to the connecting piece 2, avoiding the instability or collapse of the overall structure due to the breakage of the locking rod 304, effectively reducing the damage to the structure caused by vibration, and improving the seismic resistance of the overall structure.

[0027] Embodiment 5, as Figure 1-Figure 9 As shown, a connecting groove 14 is provided on the opposite side of the cross beam 5, a connecting rod 15 is slidably installed inside the connecting groove 14, a connecting spring 16 is sleeved on the surface of the connecting rod 15, and one end of the connecting rod 15 is fixedly connected to the second wedge block 64; The connecting spring 16 can be configured to contract when the second wedge block 64 is subjected to a squeezing force, so that the first wedge block 63 drives the locking plate 62 to reset and lock the locking rod 304 .

[0028] Embodiment six, as Figure 1-Figure 9 As shown, the locking mechanism 3 and the fixing mechanism 4 are arranged in a ring in at least four groups, and a mounting frame 17 is fixedly installed at the bottom of the connecting member 2, and the mounting frame 17 is arranged in at least four groups; The provided mounting bracket 17 can be used to quickly mount the connector 2 on the surface of the support beam 1 by means of threaded connection.
