Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] According to Figures 1 - 4As shown, it includes a weighing instrument 1, a placement pad 11 is installed on the top of the weighing instrument 1, and a weighing cylinder 2 is movably placed on the top of the placement pad 11, a placement groove 21 is opened on the inner wall of the weighing cylinder 2 near the top, and four groups of fixed grooves 22 are opened on the inner wall of the bottom end of the placement groove 21, magnet rods 23 are installed on the inner walls of the bottom ends of the fixed grooves 22, and two groups of rubber balls 24 are installed on the side walls of the fixed grooves 22, the magnet rod 23 is in the shape of a cross, and the outer frame size of the magnet rod 23 is adapted to the inner frame size of the cross groove 37.

[0021] The placement groove 21 is overlapped with a cover plate 3, and a material injection tube 31 is installed at the top of the cover plate 3. The outer diameter of the cover plate 3 is adapted to the inner diameter of the placement groove 21, and the side surface of the cover plate 3 is arranged in a close contact with the inner wall of the placement groove 21. An injection hole 32 is opened inside the cover plate 3, and a sealing plug 33 is installed at the middle position of the bottom end of the cover plate 3. The injection hole 32 runs through the inside of the cover plate 3, and the inner diameter of the injection hole 32 is adapted to the inner diameter of the injection tube 31. A conical groove 34 is opened inside the sealing plug 33, and the bottom end of the cover plate 3 is close to the edge. Four groups of fixing rods 35 are installed at the positions, and the side surfaces of the fixing rods 35 are provided with card slots 36 at the positions on both sides. The four groups of fixing rods 35 are arranged in a one-to-one correspondence with the four groups of fixing slots 22. The outer diameter of the rubber ball 24 is adapted to the inner diameter of the card slot 36, and the rubber ball 24 is located inside the card slot 36 for limited clamping. The outer diameter of the fixing rod 35 is adapted to the inner diameter of the fixing slot 22, and one end of the fixing rod 35 extends into the interior of the fixing slot 22 and is movably clamped therewith, and the bottom end of the fixing rod 35 is provided with a cross slot 37.

[0022] When it is necessary to weigh the block medicine, the user can place the block medicine directly inside the weighing cylinder 2, and then the block medicine can be weighed and measured by the weighing instrument 1. After the measurement, the user can remove the weighing cylinder 2 from the top surface of the placement pad 11, and invert the block medicine inside the weighing cylinder 2 to the designated drug storage position.

[0023] When it is necessary to weigh powdery drugs, the user can place the cover plate 3 from top to bottom inside the placement groove 21, so that the four groups of fixing rods 35 can respectively extend into the corresponding fixing grooves 22, so that the magnet rods 23 can then extend into the cross grooves 37. As a result, the top surface of the magnet rod 23 can be fitted and adsorbed to the inner wall of the top end of the cross groove 37 for corresponding adsorption and fixation. At the same time, the two rubber balls 24 will then extend into the corresponding card slots 36 and be correspondingly limited and clamped. Thus, the fixing rods 35 can be limited and clamped inside the fixing grooves 22. After that, the user can inject powdery drugs into the weighing cylinder 2 through the feeding pipe 31 and the feeding hole 32. During this process, the settings of the cover plate 3 and the sealing plug 33 can prevent the phenomenon of dust flying during the injection of powdery drugs. After the injection is completed, the powdery drugs can be weighed and measured by the weighing instrument 1. After the measurement is completed, the user can move the weighing cylinder 2 to the designated drug storage position and invert the weighing cylinder 2. Since the inner part of the sealing plug 33 is provided with a conical groove 34, the powdery drugs inside the weighing cylinder 2 can be inverted to the designated drug storage position through the conical groove 34, the feeding hole 32 and the feeding pipe 31.
