A slot 170 is opened at the top of the sealing gasket 160, and the fixing sleeve 215 passes through the slot 170 and extends from the top of the sealing gasket 160.

[0034] The bottom plate 200 includes two first support plates 210 symmetrically arranged, two second support plates 220 located between the two first support plates 210, and a third support plate 230 located between the first support plate 210 and the second support plate 220. The first support plate 210 is provided with a first clamping plate 211 on the arc side, and a guide groove 212 is provided on the side wall of the first clamping plate 211. A through groove is provided at the middle position of the top of the guide groove 212, which extends all the way to the top of the first support plate 210 to facilitate the guide plate 222 to enter the guide groove 212 from the through groove. A limiting groove 213 is provided on the top of the first clamping plate 211, and a second clamping plate 221 is provided on the arc side of the second support plate 220. The symmetrical side walls of the two support plates 220 are installed with guide plates 222, which extend into the guide groove 212. A second limiting groove 223 is provided on the top of the second support plate 220. A limiting plate 231 is installed on the outer ring of the third support plate 230. The bottom of the limiting plate 231 abuts against the bottom of the limiting groove 213 and the second limiting groove 223. A fixing sleeve 215 is installed on the top of the first support plate 210. A first threaded hole 216 communicating with the inner cavity of the fixing sleeve 215 is provided on the outer wall of the fixing sleeve 215. A threaded rod 217 is provided inside the first threaded hole 216. A first elastic member 214 is installed at the bottom of the first support plate 210, and a second elastic member 224 is installed at the bottom of the second support plate 220. , an ear plate 232 is installed at the bottom of the third support plate 230, and a connecting rod 233 is hinged on the side wall of the ear plate 232. A slider 234 is hinged on the other end of the connecting rod 233, and a second guide plate 235 is installed on the side wall of the slider 234. When assembling the bottom plate 200, first, the first clamping plate 211 on the outer wall of the two first support plates 210 is embedded in the card slot 120, and the two first support plates 210 are fixed to the bottom position of the sleeve 110. At this time, the guide plates 222 on the side walls of the two second support plates 220 are inserted into the guide slot 212 from the through slot at the top of the guide slot 212, and the two second support plates 220 are pushed to move in the opposite direction. The guide plates 222 slide in the guide slot 212 until Until the second clamping plate 221 is embedded in the clamping slot 120, the two first support plates 210 and the two second support plates 220 are combined to form a disc with the same diameter as the bottom opening of the sleeve 110. The size of the hole between the two first support plates 210 and the two second support plates 220 is consistent with the third support plate 230. The third support plate 230 is embedded in the hole to limit the first support plate 210 and the second support plate 220. The bottom of the limiting plate 231 abuts against the bottom of the limiting groove 213 and the second limiting groove 223. The two first support plates 210, the two second support plates 220 and the third support plate 230 form a disc structure to close the bottom opening of the sleeve 110.

[0035] The support structure 300 includes a bolster 310, a support column 320 installed at the bottom of the bolster 310, a reinforcement beam 330 installed on the steel rod of the support column 320, and a reinforcement rod 340 connected between the reinforcement beam 330 and the bolster 310.

The threaded rod 217 rotates through the first threaded hole 216 and the second threaded hole 321. When the base plate 200 is assembled at the bottom of the sleeve 110 to close the opening at the bottom of the sleeve 110, the bottom end of the support column 320 is inserted into the fixing sleeve 215, and the threaded rod 217 is rotated so that the threaded rod 217 rotates through the first threaded hole 216 and the second threaded hole 321 to fix the bottom end of the support column 320 inside the fixing sleeve 215. The bottom ends of the two support columns 320 are respectively connected to the two fixing sleeves 215 to increase the firmness of the support structure 300.

[0036] The buffer structure 400 includes a base plate 410, a spring 420 installed on the top of the base plate 410 and connected to the bottom of the third support plate 230, side plates 430 installed at the edges on both sides of the top of the base plate 410, and a second guide groove 440 opened on the side wall of the side plate 430. The second guide plate 235 extends through the second guide groove 440. When the bottom of the buffer structure 400 contacts the bottom load-bearing beam, the buffer structure 400 moves toward the base plate 200, squeezing the second guide plate 235 to slide inside the second guide groove 440. The spring 420 cooperates with the first elastic member 214 and the second elastic member 224 to buffer the force, so that the hard contact between the base plate 200 and the load-bearing beam is converted into elastic contact, thereby preventing damage to the base plate 200.
