[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-2 A medicine box with a locking mechanism includes a fixing block 100 (which is also the outer shell), the fixing block 100 has M rows of medicine storage areas, each row of medicine storage areas has N medicine storage units 200, where M and N are both integers greater than 2, and the fixing block 100 is equipped with a locking mechanism 300.

[0028] like Figure 3 , Figure 10-13 The medicine storage unit 200 includes a medicine storage chamber 201. A medicine chamber frame 202 is provided on the outside of the medicine storage chamber 201. The medicine chamber frame 202 is fixed on the fixing block 100. A unit door 210 is provided on the outside of the medicine chamber frame 202. One end of the unit door 210 is rotatably connected to one end of the medicine chamber frame 202 through a pin A228. The other end of the medicine chamber frame 202 is provided with a through hole 203. The other end of the unit door 210 is provided with a locking rod 340.

[0029] like Figure 9 The lower end of the locking rod 340 is the locking hook 341.

[0030] like Figure 9 , Figure 12 Each locking cavity rod 340 is matched with a locking tongue rod 330. The locking tongue rod 330 is fixed on the pin B331, and the pin B331 is rotatably connected to the fixing block 100. The upper end of the locking tongue rod 330 is a locking tongue hook 332 that matches the locking cavity hook 341.

[0031] Each medicine storage unit 200 is equipped with a locking lever 330, and N locking levers 330 are arranged in parallel.

[0032] like Figure 3-8, the locking mechanism 300 has at least one locking unit. The locking unit includes a lock core 390 and M lock core rods 320. One end of each lock core rod 320 is fixed with an end rod 310. The ends of the M end rods 310 are all rotatably connected to the connecting rod 311, and the M end rods 310 are parallel and equal.

[0033] Each lock core rod 320 is in a "Ji" shape. The lock core rod 320 includes a main horizontal plate 329, two vertical plates 328, and two short horizontal plates 327 that are fixedly connected in series. A rotating shaft 321 is fixed on each vertical plate 328. The rotating shaft 321 is rotatably connected to the fixed block 100, so that the fixed block 100, the connecting rod 311, and any two end rods 310 form a parallelogram four-bar linkage mechanism. The four hinge points are: the rotating connection points of the two rotating shafts 321 and the fixed block 100, and the rotating connection points of the two end rods 310 and the connecting rod 311.

[0034] The end rod 310 is fixed on the short horizontal plate 327.

[0035] One of the lock core rods 320 is fixed on the lock core 390. The lock core 390 is rotatably connected to the fixed block 100, and the axis of the lock core 390 coincides with the axis of the rotating shaft 321.

[0036] Among them, one lock core rod 320 in each row and N lock tongue rods 330 and N lock cavity rods 340 form a locking unit. A locking unit controls one row of the medicine storage units 200, which is also a certain improvement.

[0037] Such as Figure 12 , for convenient locking, a guiding inclined surface is provided on the outer side surface 333 of the lock tongue hook 332 of the lock tongue hook and the outer side surface 342 of the lock tongue hook of the lock cavity hook 341 for relevant cooperation.

[0038] Such as Figure 10 , for convenient opening of the unit door 210, a torsion spring A 360 is provided between the medicine storage unit 200 and the unit door 210. One rotating arm A 361 of the torsion spring A 360 contacts the medicine storage chamber 201 or the medicine chamber frame 202, and the other rotating arm B 362 contacts the unit door 210.

[0039] Such as Figure 10 , for convenient locking, a torsion spring B 338 is provided between the pin shaft B 331 and the fixed block 100. The torsion spring B 338 is sleeved outside the pin shaft B 331.

[0040] Such as Figure 10 , for convenient connection of the sensor bracket, a bolt 280 for connecting with the sensor bracket is provided on the medicine storage unit 200.

[0041] Its working principle is:

[0042] Locking:

[0043] S11, such as Figure 9-12 When you press the unit door 210 with your hand, the unit door 210 and the locking rod 340 rotate downwards simultaneously, causing the torsion spring A360 to be compressed.

[0044] S12. During the downward movement of the locking rod 340, the outer side 342 of the locking hook presses against the outer side 333 of the locking hook, applying a torque to the locking rod 330, causing the locking rod 330 to rotate counterclockwise around the pin B331 until the locking hook 341 has completely passed the outer side 333.

[0045] S13. After the locking hook 341 has completely passed the outer side 333, under the action of the torsion spring B338, the locking tongue rod 330 rotates clockwise around the pin B331, causing the locking tongue hook 332 to move above the locking hook 341.

[0046] S14. Release the hand pressing the unit door 210. Under the action of the torsion spring A360, the unit door 210 and the locking cylinder rod 340 rotate upward synchronously until the locking tongue hook 332 blocks the upward movement of the locking cylinder hook 341. The unit door 210 can no longer move upward, and the locking is completed.

[0047] Unlock:

[0048] S21, such as Figure 1-12 When a key is inserted into the lock cylinder 390 and rotated counterclockwise, the lock cylinder rod 320 rotates clockwise around the axis of the pivot 321. At the same time, the end rod 310 and the connecting rod 311 drive the other lock cylinder rods 320 to rotate clockwise around the axis of the pivot 321.

[0049] S22. All lock cylinder rods 320 are rotated clockwise to unlock all unit doors 210. See steps S23-S25 for details.

[0050] S23. When the lock cylinder rod 320 rotates clockwise, the vertical plate 328 moves the lower end of the lock tongue rod 330, applying a torque to the lock tongue rod 330, causing the lock tongue rod 330 to rotate counterclockwise around the pin B331 until the lock tongue hook 332 is completely away from the lock cavity hook 341.

[0051] S24. With the locking hook 332 no longer restrained, the unit door 210 and the locking cylinder rod 340 rotate upward synchronously under the action of the torsion spring A360.

[0052] S25. When the locking hook 341 moves above the locking tongue hook 332, the locking hook 341 rotates upward without any obstruction, and the unit door 210 can continue to rotate, and the unit door 210 is opened.

[0053] Features of this application:
