The locking device 26 includes: a top cover 261, an unlocking button 262, a locking pin 263, and a mounting cavity 264; wherein, one end of the installation cavity 264 is connected with the isolated delivery device 2, the other end of the installation cavity 264 is connected with the top cover 261, and the unlocking button 262 can slide in the installation cavity 264; the locking pin 263 is rotatably connected to the unlocking button 262 by a pin shaft, so that the locking pin 263 can be clamped in the locking groove 164 of the shutter 161 or can be accommodated in the installation cavity 264.

Preferably, as shown in fig. 10-11, the unlocking button 262 is provided with a locking pin mounting part 262-1, a locking spring mounting part 262-2 and a sliding part 262-3; the pin shaft of the locking pin 263 is rotatably connected with the locking pin mounting part 262-1 through a torsion spring (not shown in the figure), and the direction of a pre-tightening force of the torsion spring is set to enable the locking pin 263 to turn outwards when not hindered by external force, so that the locking pin 263 can be clamped in the locking groove 164; a locking spring (not shown in the figure) is installed in the locking spring installation part 262-2, one end of the locking spring abuts against the bottom end of the installation cavity 264, and the other end of the locking spring abuts against the bottom end of the locking spring installation part 262-2, so that a reset force is provided for the unlocking button 262; the sliding portion 262-3 slides in an unlocking sliding groove formed in the mounting cavity 264, so that the unlocking button 262 can slide along the length direction of the mounting cavity 264, wherein, referring to fig. 12-14, the width of the unlocking sliding groove is smaller than the width of the locking pin 263, so that the side wall of the mounting cavity 264 can form a certain obstruction to the locking pin 263, and the locking pin 263 can be smoothly accommodated in the mounting cavity 264.

Preferably, as shown in fig. 10 to 15, an elastic part 262-4 is further provided at a lower side of the sliding part 262-3; as shown in fig. 15 in particular, a slight angle is formed between the elastic part 262-4 and the length direction of the mounting cavity 264, a substantially hook-shaped part is arranged at the end of the elastic part 262-4, and a receiving part 264-1 matched with the hook-shaped part is arranged at the bottom end of the mounting cavity 264; when the unlocking button 262 moves to the bottom end of the installation cavity 264, the elastic part 262-4 can be inserted into the accommodating part 264-1, and the hook part is clamped in the accommodating part 264-1, so that the unlocking button 262 is fixed. It should be noted that, in order to facilitate the smooth insertion of the elastic portion 262-4 into the accommodating portion 264-1, a corresponding chamfered portion or a circular arc portion may be further disposed at the opening position of the accommodating portion 264-1, so as to facilitate the insertion of the elastic portion 262-4. In order to release the fixation of the unlocking button 262, an elastic unlocking protrusion 165 is further arranged in the stopping hole 162, an unlocking protrusion sliding groove 264-2 is formed along the length direction of the installation cavity 264, the unlocking protrusion sliding groove 264-2 is communicated with the inside of the accommodating part 264-1, and the unlocking protrusion 165 can slide in the unlocking protrusion sliding groove 264-2; the height of the unlocking protrusion 165 is set to be greater than or equal to the depth of the hook-shaped portion in clamping connection with the accommodating portion 264-1 along the radial direction of the installation cavity 264, so that when the hook-shaped portion moves to be opposite to the unlocking protrusion 165, the unlocking protrusion 165 drives the hook-shaped portion to move along the radial direction of the installation cavity 264 and separate from the accommodating portion 264-1. As shown in fig. 13 to 15, the width of the accommodating portion 264-1 is greater than or equal to the width of the elastic portion 262-4, the width of the elastic portion 262-4 is greater than the width of the unlocking protrusion sliding groove 264-2, and the position of the unlocking protrusion 165 is set as follows: the distance D between the unlocking protrusion 165 and the hook is preferably not too large, about 5-10mm, preferably 5mm, when the locking device 26 is completely inserted into the stopper hole 162. It should be noted that, in the above embodiment, the unlocking protrusion sliding groove 264-2 is partially disposed along the length direction of the installation cavity 264, so that the unlocking protrusion 165 can not only release the fixing of the unlocking button 262, but also the elastic unlocking protrusion 165 can provide a certain pre-tightening force to the locking device 26 in the radial direction of the locking device 26, thereby making the connection between the locking device 26 and the baffle 161 more stable. Of course, if the elastic unlocking protrusion 165 is not required to provide the pre-tightening force, it can be set as follows: the unlocking protrusion sliding groove 264-2 may also be disposed along the length direction of the installation cavity 264, so that when the locking device 26 moves in the stopping hole 162, the unlocking protrusion 165 does not form a block or pretension to the locking device 26. The two different setting modes can be selected by the person skilled in the art according to the actual needs.

In addition, as another embodiment, an accommodating cavity for accommodating the unlocking protrusion 165 may be provided in the stopper hole 162, and the unlocking protrusion 165 may be telescopically arranged in the radial direction of the mounting cavity 264, for example, in the form of a compression spring, an air cylinder, or the like, so that the unlocking protrusion 165 is accommodated in the accommodating cavity when the hook is not opposed to the hook, and when the hook is moved to be opposed to the unlocking protrusion 165, the unlocking protrusion 165 drives the hook to move in the radial direction of the mounting cavity 264 to be disengaged from the accommodating cavity 264-1.

Next, the operation of the locking device 26 according to the present invention will be described. First, in an initial state, the medical staff presses the unlocking button 262 to move downward, so that the elastic part 262-4 is inserted into the accommodating part 264-1, and further the hook part is snapped in the accommodating part 264-1, thereby fixing the unlocking button 262. In the process of moving the unlocking button 262 downwards, the locking pin mounting part 262-1 drives the locking pin 263 to move downwards together, so that the locking pin 263 is accommodated in the mounting cavity 264, and the final state is as shown in fig. 14.

The isolation transport device 2 is placed on the bottom plate 16, moved along the slide rail 17 by the driving gear 15, and finally the locking device 26 is inserted into the stop hole 162. In the process, when the hook portion of the locking device 26 is moved to be opposite to the unlocking protrusion 165, the unlocking protrusion 165 drives the hook portion to move in the radial direction of the installation cavity 264 to be disengaged from the receiving portion 264-1, thereby releasing the locking of the unlocking button 262. The return spring drives the release button 262 to move upward along the length of the mounting cavity 264. In this process, since the direction of the pre-tension force of the torsion spring is set such that the locking pin 263 is turned outwards when not being hindered by an external force, the locking pin 263 is turned outwards during the movement of the unlocking button 262 and is finally caught in the locking groove 164, so that the isolation conveyor 2 is stably fixed to the base plate 16, and the final operation state thereof is as shown in fig. 11.

When it is necessary to transfer the isolation conveyance device 2 to another place, the locking device 26 is reversed from the aforementioned operation. First, the medical staff presses the unlocking button 262 to move downward, so that the elastic part 262-4 is inserted into the accommodating part 264-1, and further the hook part is caught in the accommodating part 264-1, thereby fixing the unlocking button 262. At this time, the driving motor 15 is controlled to rotate in the reverse direction, so that the barrier conveyor 2 moves in the reverse direction along the slide rail 17, and finally the locking device 26 is disengaged from the stopper hole 162. In this process, since the driving motor 15 is controlled to rotate reversely when the unlocking button 262 is pressed to the fixed position, and since the distance D between the unlocking protrusion 165 and the hook is not large, the unlocking protrusion 165 will pass the hook quickly, and since the unlocking button 262 is still pressed, the process will not cause the unlocking operation of the unlocking button 262. Subsequently, the locking device 26 is smoothly disengaged from the stopper hole 162 by the driving of the driving motor 15, and the operation state is as shown in fig. 14.
