[0033] The embodiments of the utility model provide an unlocking mechanism, a scheduling device and a sample analyzer, which are used to solve the problems in the prior art that the anti-slip mechanism and the unlocking mechanism of the scheduling equipment have complex structures, a cumbersome unlocking process and low efficiency.

[0034] In the embodiments of the present invention, please refer to Figure 1 The scheduling device includes an unlocking mechanism 10 and a basket 20. The basket 20 is used to carry a sample rack, and the sample rack is used to carry a sample container. The unlocking structure 10 is used in conjunction with the basket 20, that is, the unlocking mechanism 10 is used to unlock the limiting mechanism on the basket 20 so that the sample rack can be taken out of the basket 20.

[0035] For unlocking mechanism 10, please refer to Figures 2 to 3 It includes a mounting frame 11, a lifting assembly 12 and a trigger 13. The mounting frame 11 is used to install the unlocking mechanism 10 on the body of the dispatching device. The lifting assembly 12 is arranged on the mounting frame 11. The lifting assembly 12 is connected to the trigger 13 to drive the trigger 13 to rise or fall, so that the trigger 13 moves between the initial position and the trigger position. At the trigger position, the trigger 13 can push the limiting mechanism 22 on the basket 20 to convert the limiting mechanism 22 from the limiting state to the unlocking state.

[0036] For basket 20, please refer to Figure 3 and Figure 4, which includes a shell 21 and a limiting mechanism 22, the shell 21 includes a bottom 211 and a side wall 212, the bottom 211 and the side wall 212 define a storage space for placing a sample rack, the limiting mechanism 22 includes a limiting member 221 and a fixing assembly 222, the middle part of the limiting member 221 is rotatably connected to the bottom 211, one end of the limiting member 221 extends upward to form a limiting portion 2211, the limiting portion 2211 can form a limit on the four sides of the sample rack together with the side wall 212, the other end of the limiting member 221 forms an unlocking portion 2212, the unlocking portion 2212 is used to receive the thrust of the trigger member 13, the limiting member 221 includes a limiting state for limiting the side of the sample rack and an unlocking state for releasing the limit on the side of the sample rack, the fixing assembly 222 is connected between the bottom 211 and the limiting member 221, and the fixing assembly 222 is used to generate a pre-tightening force on the limiting member 221, so that the limiting member 221 can be maintained in the limiting state.

[0037] Please refer to Figure 5 The working process of the scheduling device is as follows: the first transfer device (not shown in the figure) on the scheduling device transports the basket 20 to the top of the unlocking mechanism 10. At this time, the limiting member 221 is kept in a limited state due to the action of the fixing assembly 222, that is, it is blocked by the limiting portion 2211 on the side of the sample rack; then the lifting assembly 12 works to drive the trigger member 13 to move upward from the initial position to the trigger position. During the upward movement, the trigger member 13 gradually contacts the limiting portion 2211 of the limiting member 221, so that the limiting member 221 can overcome the elastic force of the fixing assembly 222 and rotate, so that the limiting portion 2211 rotates downward to the unlocking state. At this time, the limiting portion 2211 no longer blocks the side of the sample rack, and the second transfer device on the scheduling device takes the sample rack out of the basket 20.

[0038] The basket 20 adopts a limiting member 221 and a fixing assembly 222 to connect to form a limiting mechanism 22, which has a simple structure.
