Description

Technical Field

[0001] The utility model relates to the technical field of drug testing, in particular to a powder extractor. Background Art

[0002] When preparing drugs, powders are usually taken out with a medicine spoon. However, the medicine spoon currently used is easy to scatter the powder when taking it out, resulting in part of the powder being wasted.

[0011] Furthermore, a push-pull convex plate is provided on the movable plate, and the push-pull convex plate passes through the movable opening, so that the push-pull operation of the push-pull rod can be facilitated by the push-pull convex plate.

[0012] Furthermore, a conical surface is formed on the peripheral side of the end cover plate, and the conical surface of the end cover plate contacts the conical surface of the arc plate. The setting of the conical surface can improve the sealing effect between the end cover plate and the arc plate.

[0013] Furthermore, a pair of limit plates are provided at the upper end of the end cover plate, and the limit plates act on the inner side of the cover plate to limit the rotation of the end cover plate to control the rotation angle of the end cover plate.

[0014] The advantages of the above technical solution are:

[0015] The utility model facilitates the taking of medicine powder, and after taking, a sealed operation mode is used to prevent the medicine powder from being scattered. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1~Figure 4As shown, a powder extractor comprises a rod body 1, the outer end of the rod body 1 is provided with a handle 10, the inner end of the rod body 1 is provided with a connector 12, the other end of the connector 12 is provided with an end head 13 with a quarter spherical shell structure, the other end of the end head 13 is formed with a half arc plate 14, the outer end of the arc plate 14 is formed with a conical surface so that the outer end of the arc plate 14 is a blade-shaped structure.

[0022] A ring 2 is sleeved on the rod body 1, and a pair of convex plates 20 are provided on the outer periphery of the ring 2. A connecting plate 21 is provided on the ring 2. A sleeve 40 is provided at the other end of the connecting plate 21. The other end of the sleeve 40 is connected to a connecting end plate 22. A cover plate 23 is provided at the lower end of the connecting end plate 22. An end push plate 24 is provided at the inner end of the cover plate 23. A scraper 25 is provided on the end push plate 24. The cross-section of the scraper 25 is a wedge-shaped structure, and the outer end of the scraper 25 is a small end. The end push plate 24 is located in the arc plate 14.

[0023] The sleeve 40 is provided with a movable opening 26 , a movable plate is movably provided inside the sleeve 40 , a push-pull convex plate 28 is provided on the movable plate, and the push-pull convex plate 28 passes through the movable opening 26 . A push-pull rod 27 is provided on the movable plate, and a spring is provided at the inner end of the push-pull rod 27. The spring is located in the sleeve 40, and the spring is located on the inner side of the movable plate. A movable vertical plate 30 is provided at the other end of the push-pull rod 27. A pair of guide plates 31 are sleeved at the lower end of the movable vertical plate 30. The guide plate 31 is installed on the cover plate 23. A rack 29 is provided at the upper end of the movable vertical plate 30, and a gear 32 is meshed on the rack 29. An end cover plate 33 is hinged at the other end of the cover plate 23. The gear 32 is arranged on the hinged end of the end cover plate 33. The end cover plate 33 has a semicircular structure, and a conical surface is formed on the circumferential side of the end cover plate 33. The conical surface of the end cover plate 33 contacts the conical surface of the arc plate 14. A pair of limit plates 34 are provided at the upper end of the end cover plate 33. The limit plates 34 act on the inner side of the cover plate 23 to limit the rotation of the end cover plate 33.

[0024] In a specific application of this embodiment, an operator opens the bottle cap of the medicine powder.

[0025] Then the operator puts the arc plate 14 into the powder bottle and takes a certain amount of powder through the arc plate 14. When taking the powder, the end cover plate 33 is opened due to the elastic force of the spring.

[0026] Then the operator takes a certain amount of medicine powder. When the taking is completed, the operator pushes the rack 29 by pushing and pulling the convex plate 28, so that the rack 29 drives the gear 32 to rotate, and the rotation of the gear 32 will cause the end cover plate 33 to rotate downward, and then the end cover plate 33 is covered on the arc plate 14, and it is also necessary to ensure that the conical surface of the end cover plate 33 is in contact with the conical surface of the arc plate 14.

[0027] Then the operator takes the arc plate 14 out of the bottle and transfers it to a container or weighs the powder. When putting the powder in, the operator first cancels the push on the push-pull convex plate 28, and then pushes the rack 29 to move backward under the elastic force of the spring, and the movement of the rack 29 interacts with the gear 32, and the end cover plate 33 rotates outward, and then the powder is put into the container, and then the ring 2 is pushed to scrape the powder out through the scraper 25.
