[0038] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0039] Please also refer to Figure 1-Figure 5 This embodiment provides a CT vehicle, including a vehicle body 1 and a testing bed 2, and also includes a motor body 3, a pushing assembly 4, a first hook 5, a transmission mechanism 6, a second hook 7 and a lifting mechanism 8.

[0040] The examination bed 2 is installed within the vehicle body 1. A sliding cavity 11 is provided within the bottom surface of the vehicle body 1 beneath the examination bed 2. The inner bottom surface of the vehicle body 1 also includes a long sliding hole 12 that communicates with the sliding cavity 11. It should be understood that a CT scanner is installed at the head of the examination bed 2. It should also be understood that the sliding cavity 11 is located between the inner and outer bottom surfaces of the vehicle body 1.

[0041] The motor body 3 is housed within the sliding cavity 11 and connected to the push assembly 4. The motor body 3 drives the push assembly 4 to slide back and forth. The push assembly 4 is slidably disposed within the sliding cavity 11 and connected to a first hook through an elongated sliding hole 12. The first hook is retractable, with its fixed end located on the side of the testing bed 2. It should be understood that the first hook and the elongated sliding hole 12 correspond one-to-one. The end of the first hook facing away from the testing bed 2 is the retractable end and is connected to the push assembly 4. This retractable end is equipped with an upward-pointing baffle. When extended, the first hook can pass between the two lifting mechanisms 8, that is, between the two second hooks 7. In this embodiment, two first hooks are provided.

The motor connecting rod 41 is provided at the rotating end of the motor body 3, the slider connecting rod 42 is hinged to the motor connecting rod 41 at one end, and hinged to the slider body at the other end. The slider body is slidably connected to the sliding cavity 11, and the push rod 44 is connected to the telescopic end of the first hook through the long sliding hole 12. The rack 45 is provided on the slider body, and the sliding of the rack 45 can drive the transmission mechanism 6 to rotate, thereby driving the two lifting mechanisms 8 to slide. It should be understood that the slider body is an inverted "concave" shaped block, the rack 45 is provided in the middle recess thereof, and the push rod 44 corresponds to the first hook one-to-one. Preferably, a telescopic baffle is further provided on the long sliding hole 12, and the push rod 44 passes through the telescopic baffle and is connected to the first hook. When the slider body is not sliding, the telescopic baffle closes the long sliding hole 12. When the slider body slides, the telescopic baffle shortens, gradually revealing the long slider.

Multiple sets of driven assemblies 62 are provided and rotatably disposed within the sliding cavity 11. The rotation of the rotating assembly 61 can cause the multiple lifting mechanisms 8 to slide via the multiple sets of driven assemblies 62. That is, the sliding of the rack 45 drives the rotating assembly 61 to rotate, the rotation of the rotating assembly 61 drives the multiple driven assemblies 62 to rotate, and the rotation of the multiple driven assemblies 62 drives the lifting mechanisms 8 to slide, thereby causing the second hook 7 to rise and fall.

It should be understood that the second bevel gear 623 at one end of a driven assembly 62 meshes with the first bevel gear 614 of the rotating assembly 61, and the second bevel gear 623 at the other end meshes with the second bevel gears 623 of the remaining driven assemblies 62, respectively. The remaining driven assemblies 62 are respectively connected to the lifting mechanism 8, that is, the rotation of one driven assembly 62 causes the remaining driven assemblies 62 to rotate, thereby causing the lifting mechanism 8 to slide. Specifically, in this embodiment, there are three groups of driven assemblies 62, one of which has one end meshed with the rotating assembly 61 and the other end meshed with the other two driven assemblies 62. The other two driven assemblies 62 are arranged opposite each other and are respectively connected to different lifting mechanisms 8, that is, the remaining two driven assemblies 62 correspond one to one with the lifting mechanism 8.

The end of the second hook 7 away from the vehicle body 1 is provided with a baffle upward. In addition, as an option, the second hook 7 is detachably provided on the lifting mechanism 8. There are at least two second hooks 7. When the second hook 7 is raised to its highest point, it is higher than the inner bottom surface of the vehicle body 1 and the first hook. At the same time, the first hook passes through the second hook 7. When the second hook 7 is lowered, when the stretcher on the second hook 7 is placed on the first hook, the baffle of the first hook is placed on the side of the stretcher away from the vehicle body 1.

[0048] When the push assembly 4 slides outward, the first hook is extended, the second hook 7 is lifted, and the first hook passes through between the two lifting mechanisms 8; when the push assembly 4 slides inward, the second hook 7 is lowered and the first hook is shortened.
