Furthermore, the middle slide rail set 3 includes a front middle slide rail 301 and a rear middle slide rail 302. The lower side of the front middle slide rail 301 is sleeved in the lower front lower concave guide chute 111, the upper left side of the front middle slide rail is sleeved in the left front upper concave guide chute 211, and the upper right side of the front middle slide rail is sleeved in the right front upper concave guide chute 213. The rear middle slide rail 302 is sleeved at the lower side of the lower rear lower concave guide chute 112, at the left upper side of the rear middle slide rail is sleeved at the left rear upper concave guide chute 212, and at the right upper side of the rear middle slide rail is sleeved at the right rear upper concave guide chute 214.

The lower contact group 4 includes a left front lower roller wheel group 41, a right front lower roller wheel group 42, a left rear lower roller wheel group 43, and a right rear lower roller wheel group 44. The left front lower rolling wheel set 41 is disposed on the left lower side of the front middle sliding rail 301 and contacts with the left lower front lower concave arc 1211. The right front lower rolling wheel group 42 is disposed on the lower right side of the front middle slide rail 301, and contacts with the lower right front lower concave arc position 1212. The left rear lower roller set 43 is disposed on the lower left side of the rear middle slide rail 302 and contacts the lower left rear lower concave arc 1221. The right rear lower roller set 44 is disposed on the lower right side of the rear middle rail 302 and contacts the lower right rear lower concave location 1222.

The upper contact group 5 includes a left front upper roller set 51, a right front upper roller set 52, a left rear upper roller set 53, and a right rear upper roller set 54. The left front upper rolling wheel set 51 is disposed on the left upper side of the front middle slide rail 301, and contacts with the left front upper concave arc position 221. The right front upper rolling wheel set 52 is disposed on the upper right side of the front middle slide rail 301, and contacts the right front upper concave arc 223. The left rear upper rolling wheel set 53 is disposed on the upper left side of the rear middle slide rail 302 and contacts the left rear upper concave arc 222. The right upper rear roller set 54 is disposed on the upper right side of the rear middle rail 302 and contacts the upper right rear concave arc 224. Its advantage lies in lower base 1 with it is used for blockking to weaken to go up the damping connection structure of 2 vibrations of base 2 to reach total eight places then, can improve the damping of this application more closely, and still can further reduce the frequency of trembling, and then can furthest improve the practicality and the suitability of this application, so that satisfy the real user demand, realize that furthest's protection cultural relics, precision instruments, rack etc. that this application carried put the object.

Of course, when the lower contact set 4 and the upper contact set 5 are both fixedly disposed on the middle sliding rail set 3, the material for making the lower contact set 4 and the upper contact set 5 is preferably graphite, which is intended to meet the use requirement of reciprocal movement.

Furthermore, the front and rear sides of the middle part of the front middle slide rail 301 are provided with front middle concave parts 3011 which are concave inwards. The front side and the rear side of the middle part of the rear middle sliding rail 302 are both provided with rear middle inner concave positions 3021 which are concave inwards.

The lower base 1 further comprises a lower front limiting guide group 104 and a lower rear limiting guide group 105. The lower front limiting guide set 104 is disposed on the lower front plate set 101, located on the front and rear sides of the front middle slide rail 301, and is provided thereon with a lower front limiting protrusion 1041 which can extend into the front middle concave position 3011 to limit the front middle slide rail 301. The lower rear limiting guide set 105 is disposed on the lower rear plate set 102, located on the front and rear sides of the rear middle sliding rail 302, and further provided thereon with a lower rear limiting protrusion 1051 which can extend into the rear middle concave position 3021 to limit the rear middle sliding rail 302. The front middle slide rail 301 and the rear middle slide rail 302 are limited by the lower front limiting and guiding group 104 and the rear middle slide rail 302 is limited by the lower rear limiting and guiding group 105, so that the front middle slide rail 301 and the rear middle slide rail 302 are limited respectively, the purposes of simple structure and easy realization can be achieved, and meanwhile, the processing and the assembly are convenient.

As described above, the embodiments of the present application have been described in detail, but the present application is not limited to the above embodiments. Even if various changes are made in the present application, the protection scope of the present application is still included.
