[0038] In some embodiments, the motion device further includes a second sliding unit and a counterweight block 4 , and the counterweight block is slidably disposed on the other end surface of the support portion 1 through the second sliding unit. Figure 6 for Figure 1 A schematic structural diagram of the second sliding unit of the motion device of an embodiment, wherein the second sliding unit includes a second slide rail 331 and a second slider 332 slidably matched with the second slide rail 331, and the second slider 332 can be provided with a second groove 3321 that cooperates with the second slide rail 3311, and the second slider 332 can slide along the extension direction of the second slide rail 331 through the second groove 3321. Figure 7 The schematic diagram of the structure of the counterweight block of the motion device of one embodiment of the utility model is that the conveyor belt 313 can be provided with a second connecting block 315, and the connection with the counterweight block 4 is realized through the second connecting block 315, so as to realize the synchronous movement of the second slider 332 and the conveyor belt 313, that is, the movement of the conveyor belt 313 can drive the counterweight block 4 connected thereto to move. The second connecting block 315 and the second slide rail 331 can be connected to the counterweight block 4 by a plurality of bolts. The second slide rail 331 is arranged parallel to the conveyor belt 313. The plane formed by the second slide rail 331 and the conveyor belt 313 is the sliding plane of the second sliding unit. The sliding plane of the second sliding unit is parallel to the sliding plane of the first sliding unit.

[0039] The conveyor belt 313 is connected to the sliding part 2 and the counterweight block 4 respectively through the first connecting block 314 and the second connecting block 315, that is, the connecting column 21 and the counterweight block 4 are linked, and the sliding part 2 and the counterweight block 4 are respectively arranged on the two end surfaces of the support part 1. In order to reduce the shear stress during the transmission of the conveyor belt 313 and the resistance during the motion transmission process, when the mounting end is at the position closest to the support part (retracted state), the mounting end A and the counterweight block 4 are on the same side, as shown in FIG. Figure 2 When the mounting end is at the position farthest from the support portion (extended state), the mounting end A and the counterweight block 4 are on opposite sides, see Figure 1 Preferably, the weight of the counterweight 4 is equivalent to that of the sliding part 2, which reduces the resistance of the conveyor belt during the transmission process and improves the sensitivity of the motion response of the detector unit connected to the sliding part, thereby improving the overall performance of the medical imaging device where the detector unit is located.
