[0037] The adjustment unit located in the front includes a second round rod 2019, a first linkage block 2020, a second linkage block 2021 and a second spring 2022; two second round rods 2019 are welded on the left and right sides of the sliding block 2016; a first linkage block 2020 is slidably connected between each upper and lower adjacent second round rods 2019; a second linkage block 2021 is bolted to the opposite sides of the two first linkage blocks 2020; the two second linkage blocks 2021 are meshed with the fourth connecting block 2015; a second spring 2022 is sleeved on the four second round rods 2019, one end of the second spring 2022 is welded to the adjacent first linkage block 2020, and the other end of the second spring 2022 is welded to the adjacent second round rod 2019.

[0038] The fourth connecting block 2015 has a plurality of undercuts on the left and right sides, and the second linkage block 2021 has two undercuts on the side close to the fourth connecting block 2015 , and the two undercuts are meshed with each other, and the two undercuts are used to adjust and fix the position of the sliding block 2016 .

[0039] During the preparation work, the first connecting plate 1 is manually fixed to the substructure, and the second connecting plate 2 is manually fixed to the superstructure. The first elastic bands 2014 on the front and rear sides are in a tight state, and the first elastic bands 2014 on the left and right sides are in a relaxed state. When the superstructure vibrates due to various usage scenarios, the second connecting plate 2 is squeezed, and the second connecting plate 2 drives the movable column 204 to move downward, and the movable column 204 compresses the first spring 203 to achieve a buffering and shock reduction effect. During the downward movement of the movable column 204, the movable column 204 drives the connecting ring 205 to move downward, and the connecting ring 205 drives the second connecting block 206 to move downward, and the second connecting block 206 drives the upper end of the linkage rod 207 to move downward, so that the linkage rod 207 rotates around the first round rod 209, so that the lower end of the linkage rod 207 moves upward, and the lower end of the linkage rod 207 drives the parts thereon to move, thereby stretching the first elastic bands 2014 on the front and rear sides, that is, the first elastic band 2014 further eliminates the vibration, and achieves secondary shock reduction;

[0040] When the vibration amplitude is too large, the first elastic bands 2014 on the front and rear sides will lose elasticity and be damaged due to excessive stretching. At this time, the second connecting block 206 sinks more, causing the second connecting block 206 to link with the warning component to operate. Then the maintenance worker goes for maintenance, and the maintenance worker pulls the sliding block 2016 on the left to move to the left, and the maintenance worker pulls the sliding block 2016 on the right to move to the right. The sliding block 2016 drives the parts thereon to move, thereby tightening the first elastic bands 2014 on the left and right sides. At the same time, the sliding block 2016 drives the second round rod 2019 to move, and the second round rod 2019 drives the first linkage block 2020 to move, and the first linkage block 2020 drives the second linkage block 2021 to move, so that the second linkage block 2021 moves away from the cylinder 201. Since the second linkage block 2021 is engaged with the fourth connecting block 2015 through the barb, the second linkage block 2021 slides on the fourth connecting block 2015. The barb on the block 2015 blocks and limits the second linkage block 2021, so that the second linkage block 2021 pushes the first linkage block 2020 to move and compresses the second spring 2022. When the sliding block 2016 stops moving, the second spring 2022 rebounds and drives the second linkage block 2021 to re-engage the fourth connecting block 2015, thereby fixing the sliding block 2016, and then fixing the lower end of the first elastic band 2014, so that the first elastic band 2014 remains in a taut state. At this time, the auxiliary shock absorption operation is performed through the first elastic bands 2014 on the left and right sides, and then the maintenance personnel replace the first elastic bands 2014 on the front and rear sides. When in use, the maintenance personnel only need to toggle the sliding block 2016 to switch the first elastic bands 2014 on the left and right sides to the auxiliary shock absorption state. During the replacement process of the first elastic bands 2014 on the front and rear sides, they are replaced for auxiliary shock absorption, thereby avoiding a reduction in the shock absorption effect, and the switching operation is convenient and quick;

[0041] After the maintenance worker switches the first elastic bands 2014 on the left and right sides to the auxiliary shock absorption state, the maintenance worker twists the third connecting block 2012 to rotate, and the third connecting block 2012 drives the threaded ring 2011 and the locking ring 2013 to rotate, so that the threaded ring 2011 moves away from the linkage rod 207, and the threaded ring 2011 drives the third connecting block 2012 to move, so that the third connecting block 2012 drives the locking ring 2013 to move away from the linkage rod 207, so that the locking ring 2013 stops contacting the fixed block 2010, and the opening of the fixed block 2010 rebounds and stops clamping the upper end of the first elastic band 2014, and then the maintenance worker removes the upper end of the first elastic band 2014 from the fixed block 2010, and then manually screws the knob 2018 to make the knob 2018 move upward, thereby making the second elastic block 2017 rebound and stop clamping the lower end of the first elastic band 2014, and then the lower end of the first elastic band 2014 Take it out, then insert the upper end of the new first elastic band 2014 into the opening of the fixed block 2010, then screw the threaded ring 2011 back to its original position, so that the locking ring 2013 moves back to its original position to squeeze the opening of the fixed block 2010, thereby clamping the upper end of the new first elastic band 2014, and then put the lower end of the new first elastic band 2014 between the sliding block 2016 and the second elastic block 2017, and then screw the knob 2018 so that the knob 2018 moves downward, and the knob 218 squeezes the second elastic block 2017 downward, thereby pressing the lower end of the new first elastic band 2014 onto the sliding block 2016, and completing the replacement operation. When in use, by setting the fixed block 2010 and the second elastic block 2017, it is only necessary to manually perform two screwing operations to complete the replacement operation of the first elastic band 2014, which is more convenient than the prior art and is conducive to improving replacement efficiency.

[0042] After the first elastic band 2014 is replaced, the maintenance worker pushes the sliding block 2016 to move away from the cylinder 201, and the sliding block 2016 drives the parts thereon to move, thereby tightening the replaced new first elastic band 2014. There is no need to ensure that the new first elastic band 2014 is in a taut state while installing it, thereby reducing the difficulty of installation. Then, the second linkage blocks 2021 on the left and right sides are manually pulled away from the corresponding fourth connecting blocks 2015, and then the sliding blocks 2016 on the left and right sides are pushed to move toward each other, thereby loosening the first elastic bands 2014 on the left and right sides, and switching the first elastic bands 2014 on the left and right sides back to the standby state.

[0043] Implementation 2

[0044] Based on Implementation Plan 1, Figure 1-2 and Figure 9-11As shown, the warning component includes a third round rod 301, a third spring 302, a piston block 303, a first pipe 304 and a push-back unit; a third round rod 301 is slidably connected to the inner front and inner rear of the cylinder 201; a third spring 302 is sleeved on the two third round rods 301, the lower end of the third spring 302 is welded to the cylinder 201, and the upper end of the third spring 302 is welded to the third round rod 301; a piston block 303 is welded between the lower ends of the two third round rods 301; a colored solution is arranged in the lower cavity of the piston block 303; the piston block 303 is in contact with the first connecting block 202; the piston block 303 is slidably connected to the cylinder 201; the middle part of the lower side of the cylinder 201 is connected with the first pipe 304; the first pipe 304 passes through the first connecting plate 1; the push-back unit is connected to the upper left part of the first connecting plate 1; a curved portion is arranged on the upper part of the first pipe 304, and the highest point of the curved portion is higher than the piston block 303.

[0045] The push-back unit includes a connecting frame 305, a second pipe 306 and an airbag 307; the connecting frame 305 is bolted to the left upper side of the first connecting plate 1; the second pipe 306 is fixedly connected to the upper side of the connecting frame 305; the lower side of the second pipe 306 is connected to the airbag 307; the airbag 307 is connected to the first pipe 304.

[0046] When the vibration amplitude is too large, the first elastic bands 2014 on the front and rear sides will lose elasticity and be damaged due to excessive stretching. At this time, the second connecting block 206 sinks more, so that the second connecting block 206 pushes the third round rod 301 to move downward and compresses the third spring 302. The third round rod 301 drives the piston block 303 to move downward, so that the piston block 303 squeezes the colored solution on its lower side. The colored solution is squeezed into the first pipe 304, and the lower part of the first pipe 304 hangs down on the beams and columns of the lower building, so that the maintenance personnel can detect the failure of the first elastic band 2014 at the first time, so as to go for maintenance immediately;

[0047] After the maintenance is completed, the second pipe 306 is manually blocked, and then the airbag 307 is squeezed to squeeze gas into the first pipe 304, so as to push the colored solution in the first pipe 304 back into the cylinder 201, and then the blocking of the second pipe 306 is stopped, and the airbag 307 rebounds and resets. When in use, the colored solution in the first pipe 304 is squeezed back into the cylinder 201 through the airbag 307, so as to facilitate the warning operation.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
