[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-4 A fastener with an anti-seismic structure shown in FIG. 1 includes a connecting member 1, a threaded hole 10 is provided at an internal position of the connecting member 1, a threaded rubber tube 4 is connected to an internal position of the threaded hole 10, a washer A3 is fixed at an outer position of the threaded rubber tube 4, a plurality of fixing strips 5 are fixed at an inner wall position of the threaded rubber tube 4, a bolt column 2 is inserted and installed at an internal position of the threaded rubber tube 4, a slide groove 7 is located at an outer position of the bolt column 2, the fixing strip 5 is clamped in the inner position of the slide groove 7, a nut 6 is sleeved at an outer wall position of the bolt column 2, a clamping groove 11 is provided at an inner position of the nut 6, the nut 6 squeezes the washer B9 at the inner position, and the fixing block 8 located at one end of the washer B9 is clamped in the clamping groove 11.

[0023] After aligning the four sliding grooves 7 of the bolt column 2 with the four fixing bars 5, insert the bolt column 2 into the internal position of the threaded rubber tube 4, insert the bolt column 2 into the threaded hole 10 of the connector 1, rotate the bolt column 2 so that the threaded rubber tube 4 enters the threaded hole 10, and rotate it to squeeze the washer A3. Engage the fixing block 8 in the washer B9 in the slot 11 of the nut 6, and rotate the nut 6 from the lower end position of the bolt column 2 until the washer B9 is squeezed. The loosening direction of the threaded rubber tube 4 is the same as the tightening direction of the nut 6, thereby increasing the firmness of the connection.

[0024] like Figure 1 and Figure 2 As shown, the bolt column 2 aligns the slide groove 7 with the fixing strip 5 and can be inserted into the threaded rubber tube 4. The fixing strip 5 is clamped in the slide groove 7 so that the bolt column 2 can drive the washer A3 to rotate. The bolt column 2 is rotated by the tool so that the threaded rubber tube 4 enters the threaded hole 10. The rotation of the bolt column 2 causes the washer A3 to be squeezed. The nut 6 rotates along the outer wall of the bolt column 2 to squeeze the washer B9 at the lower end position of the connector 1. The washer B9 clamps the fixing block 8 fixed to it in the clamping groove 11. The clamping of the fixing block 8 in the clamping groove 11 increases the tightness of the connection between the washer B9 and the nut 6.

[0025] A fixing block 8 is provided at the outer wall of the washer, and the fixing block 8 is clamped in the slot 11 of the nut 6. The combination of the fixing block 8 and the slot 11 forms a firm locking mechanism, which can effectively prevent the washer from being displaced or rotated during use, thereby maintaining the overall stability of the connector 1 and enhancing the shock resistance and load resistance.
