The placement frame 41 is slidably provided on the top of the placement seat 3, and the first tension spring 42 is wound around the lower part of the placement frame 41. The two ends of the first tension spring 42 are respectively connected to the placement seat 3 and the placement frame 41. The first magnet frame 43 is fixedly provided on the bottom of the placement frame 41. The second magnet frame 44 is provided at the rear of the placement seat 3 by means of a bearing. The second magnet frame 44 and the first magnet frame 43 repel each other with the same polarity. The first torsion spring 45 is wound around the left part of the second magnet frame 44. The two ends of the first torsion spring 45 are respectively connected to the placement seat 3 and the second magnet frame 44.

[0035] like Figure 4 and Figure 5As shown, the medicine dispensing mechanism 5 includes a first fixed frame 51, a rotating frame 52, a second torsion spring 53, a first pulling rod 54, a second pulling rod 55, a second tension spring 56, a medicine dispensing frame 57 and a first limiting rod 58. The first fixed frame 51 is fixedly provided in the middle of the rear of the placement seat 3, and the rotating frame 52 is provided on the right side of the lower part of the first fixed frame 51 by means of a bearing. The second magnet frame 44 is in contact with the rotating frame 52. The second torsion spring 53 is wound around the first fixed frame 51, and the two ends of the second torsion spring 53 are respectively connected to the rotating frame 52 and the first fixed frame 51 A first pulling rod 54 is slidably and rotatably provided at the lower part of the rotating frame 52, a second pulling rod 55 is provided at the top of the first pulling rod 54 by means of a bearing, the second pulling rod 55 is connected to the cartridge 2 by means of a bearing, a second tension spring 56 is connected between the middle part of the second pulling rod 55 and the cartridge 2, a medicine discharging rack 57 is provided on the front side of the second pulling rod 55 by means of a bearing, the lower part of the medicine discharging rack 57 can block the cartridge 2, a first limiting rod 58 is connected between the left and right sides of the inside of the cartridge 2, and the first limiting rod 58 and the medicine discharging rack 57 are slidably connected through them.

[0036] This quantitative drug taking device for pharmacy can be used to quantitatively take out solid drugs, such as tablets, capsules, etc. First, people put the drugs into the cartridge 2, and then place the medicine bottle on the placement rack 41. Under the action of gravity, the medicine bottle makes the placement rack 41 slide downward along the placement seat 3, and the first tension spring 42 is stretched. The placement rack 41 drives the first magnet rack 43 to move downward to reach the first critical point. Since the first magnet rack 43 and the second magnet rack 44 repel each other with the same polarity, the rear part of the second magnet rack 44 will rotate upward, the first torsion spring 45 is twisted and deformed, and the second magnet rack 44 drives the front part of the rotating rack 52 to rotate around As the first fixed frame 51 rotates upward, the second torsion spring 53 is twisted and deformed, and the rear part of the rotating frame 52 drives the first pulling rod 54 to move downward. The first pulling rod 54 drives the rear part of the second pulling rod 55 to rotate downward around the cartridge 2. The front part of the second pulling rod 55 drives the medicine discharging rack 57 to slide upward along the first limiting rod 58. The second tension spring 56 is stretched. At this time, the medicine discharging rack 57 no longer blocks the bottom of the cartridge 2. The medicine in the cartridge 2 will fall into the medicine bottle. As the weight of the medicine bottle increases, the placement rack 41 and the first magnet rack 43 continue to slide downward as a whole and reach the second critical point. At this time, the first torsion spring 45 is reset and drives the second magnet frame 44 to rotate and reset in the opposite direction, and then the second torsion spring 53 is reset to drive the rotating frame 52 to rotate in the opposite direction, so that the first pulling rod 54 slides upward, and then the second pulling spring 56 is reset to drive the second pulling rod 55 to rotate and reset in the opposite direction, and then the medicine discharging rack 57 slides downward and blocks the medicine cartridge 2 again, and the medicine in the medicine cartridge 2 no longer falls. At this time, the weight of the medicine bottle placed on the placement rack 41 and the medicine in the bottle is fixed, so that quantitative loading can be achieved, and then people hold the medicine bottle and make it move upward. Since the medicine bottle no longer presses the placement rack 41, the reset of the first pulling spring 42 will drive The placement rack 41 and the first magnet rack 43 slide upward as a whole. When the first magnet rack 43 reaches the first critical point again, the second magnet rack 44 will drive the front part of the rotating rack 52 to rotate again. Finally, the medicine discharging rack 57 will slide upward again and will not block the medicine cartridge 2. The medicine in the medicine cartridge 2 falls down into the medicine bottle, realizing secondary charging. Until the first magnet rack 43 moves upward to the first critical point, the second magnet rack 44 and the rotating rack 52 continue to move upward and reset, and the medicine discharging rack 57 slides downward and blocks the medicine cartridge 2 again. At this time, the medicine bottle that has undergone secondary charging is full, and the amount of secondary charging is fixed.

[0037] Example 2

[0038] On the basis of Example 1, Figure 1 , Figure 6 and Figure 7As shown, it also includes an anti-dumping mechanism 6, which is used to protect the medicine bottle from tilting and falling. The anti-dumping mechanism 6 includes a second limiting rod 61, a limiting frame 62 and a third torsion spring 63. The second limiting rod 61 is penetrated through the middle of the first pulling rod 54, and a limiting frame 62 is symmetrically provided on the lower part of the cartridge 2 through a bearing. The limiting frame 62 limits and fixes the medicine bottle to prevent it from falling. The second limiting rod 61 is in contact with the limiting frame 62, and the upper part of the limiting frame 62 is symmetrically wound with a third torsion spring 63, and the two ends of the third torsion spring 63 are respectively connected to the limiting frame 62 and the cartridge 2.

[0039] When the first pull rod 54 moves downward, the first pull rod 54 drives the second limit rod 61 to move downward, the third torsion spring 63 in torsion deformation is reset and drives the limit frame 62 to rotate inward, the limit frame 62 will limit and fix the medicine bottle on the placement rack 41 to prevent the medicine bottle from tipping over and falling when loading medicine, and when the first pull rod 54 moves upward, the first pull rod 54 drives the second limit rod 61 to move upward, the second limit rod 61 will squeeze the limit frame 62 to make it rotate outward, and the third torsion spring 63 will torsion deformation.

[0040] like Figure 1 and Figure 8 As shown, it also includes an anti-curing mechanism 7, which prevents the medicine from getting stuck at the bottom of the cartridge 2. The anti-curing mechanism 7 includes a gear 71, a rack 72, a second fixed frame 73 and a third tension spring 74. The front part of the right limit frame 62 is fixedly provided with a gear 71, the lower part of the right side of the cartridge 2 is fixedly provided with a second fixed frame 73, and the lower part of the second fixed frame 73 is slidably provided with a rack 72, the rack 72 will contact the bottom of the cartridge 2, the upper part of the rack 72 is meshed with the gear 71, and the lower part of the second fixed frame 73 is wound with a third tension spring 74, and the two ends of the third tension spring 74 are respectively connected to the second fixed frame 73 and the rack 72.

[0041] When the limit frame 62 rotates inward, the limit frame 62 drives the gear 71 to rotate, and the gear 71 drives the rack 72 to slide upward along the second fixed frame 73, and the third tension spring 74 is stretched. Then the rack 72 will contact the cartridge 2 and knock on the bottom of the cartridge 2 to prevent some medicines from being stuck at the bottom of the cartridge 2 and not falling, making it easier to load the medicines into the medicine bottles. When the limit frame 62 rotates outward, the limit frame 62 drives the gear 71 to rotate in the opposite direction, and the gear 71 drives the rack 72 to slide downward, and the rack 72 is no longer in contact with the cartridge 2, and the third tension spring 74 is reset.

[0042] like Figure 1 and Fig. 9As shown, it also includes an opening and closing mechanism 8, which is used to open and close the protection box 1. The opening and closing mechanism 8 includes a first closing frame 81, a first hinge 82, a second hinge 83 and a fourth torsion spring 84. The upper rear side of the protection box 1 is fixedly connected to the second hinge 83 by bolts, and the upper part of the second hinge 83 is hingedly provided with the first hinge 82. The upper part of the second hinge 83 is symmetrically wound with a fourth torsion spring 84, and the two ends of the fourth torsion spring 84 are respectively connected to the second hinge 83 and the first hinge 82. The bottom of the first hinge 82 is fixedly connected to the first closing frame 81 by bolts, and the first closing frame 81 is in contact with the protection box 1. The first closing frame 81 is used to open and close the protection box 1.

[0043] When people need to add materials into the quantitative drug dispensing device for the pharmacy, by pulling the first closing frame 81 upwards, the first closing frame 81 drives the first hinge 82 to rotate upward around the second hinge 83, and the fourth torsion spring 84 is twisted and deformed. At this time, the top of the placement seat 3 is opened, and people can add materials into the quantitative drug dispensing device for the pharmacy. After the addition is completed, the first closing frame 81 is released, and the fourth torsion spring 84 is reset to drive the first hinge 82 and the first closing frame 81 to rotate downward as a whole, and the top of the placement seat 3 is closed to prevent dust from entering the quantitative drug dispensing device for the pharmacy and contaminating the drugs in the cartridge 2.

[0044] like Figure 1 and Fig.10 As shown, it also includes an emergency closing mechanism 9, which can control the speed of filling the medicine bottle. The emergency closing mechanism 9 includes a second closing frame 91, a third limiting rod 92 and a fourth tension spring 93. The second closing frame 91 is slidably provided at the bottom of the cartridge 2. A groove is provided on the front side of the second closing frame 91 to facilitate people to pull the second closing frame 91. A third limiting rod 92 is fixedly provided on the left side of the second closing frame 91. The third limiting rod 92 is slidably connected to the cartridge 2. A fourth tension spring 93 is wound around the rear of the third limiting rod 92. The two ends of the fourth tension spring 93 are respectively connected to the cartridge 2 and the third limiting rod 92.

[0045] When an emergency occurs due to external force during the loading process, people can push the second closing frame 91 backwards, and the second closing frame 91 drives the third limiting rod 92 to slide backwards, and the fourth tension spring 93 is stretched. At this time, the bottom of the cartridge 2 is blocked, and the medicine no longer falls down, thereby preventing the waste of medicine. After waiting for the emergency to be resolved, people can release the second closing frame 91, and the fourth tension spring 93 is reset to drive the third limiting rod 92 and the second closing frame 91 to slide forward as a whole, and the bottom of the cartridge 2 is no longer blocked. The quantitative medicine dispensing device for the pharmacy department can continue to load medicine, and people can also control the size of the bottom opening of the cartridge 2 by pushing the second closing frame 91, thereby controlling the speed of loading medicine into the medicine bottle.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
