The push rod sleeve 230 of the booster according to the embodiment of the present application has a certain adjustment capability in the length direction, so that the medicine bin 100 can be adapted to mount medicine bottles with different lengths, that is, when the connecting structure 200 of the embodiment of the present application is connected with the medicine bin 100, the push rod sleeve 230 in the connecting structure 200 can be adapted to abut the second end surface of the push rod sleeve 230 against the first end surface of the first end of the medicine bottle 400 under the pretightening force of the pretightening spring 600 (the first end of the medicine bottle 400 refers to the end with the movable rubber plug 420), and the push rod sleeve 230 plays a role of limiting the upward movement of the medicine bottle 400, so that the medicine bottle 400 is stably mounted in the medicine bin 100.
With the understanding of the above embodiments, referring to fig. 10, 11, 12 and 13, when the cross section of the push rod body 310 of the push rod 300 in the booster according to the embodiment of the present application is circular, the inner wall of the first end surface of the hand-held sleeve 210 may be provided with the first ratchet teeth 204, and the first end of the push rod sleeve 230 may be provided with the second ratchet teeth 234 adapted to the first ratchet teeth 204 when the hand-held sleeve 210 is in threaded connection with the drug cartridge sleeve 220. The embodiment of the application can realize that when the medicine bin 100 is internally provided with the medicine bottle 400, the connecting structure 200 is not detachable after being connected with the medicine bin 100, and when the medicine bin 100 is not internally provided with the medicine bottle 400, the connecting structure 200 is detachable after being connected with the medicine bin 100, so that the waste caused by connecting the medicine bin 100 with the connecting structure 200 by mistake when the medicine bottle 400 is not arranged in the medicine bin 100 is avoided. The following are illustrated:
The hand sleeve 210 of the booster of the embodiment is tubular, the inner wall of the first end of the hand sleeve 210 is provided with a thread groove, the first end face of the hand sleeve 210 is provided with the first through hole 202, the inner wall of the first end face of the hand sleeve 210 is provided with the first ratchet 204, the outer wall of the first end of the medicine sleeve 220 is provided with thread teeth matched with the thread groove, the second end of the medicine sleeve 220 is provided with the first buckling structure, the first buckling structure of the medicine sleeve 220 is provided with a ratchet hole, the second end of the medicine sleeve 220 is provided with a guide groove, the inner wall of the medicine sleeve 220 is provided with a first annular lug 228, in addition, the push rod sleeve 230 is tubular, the outer diameter of the push rod sleeve 230 is smaller than the inner diameter of the first annular lug 228, the outer wall of the first end of the push rod sleeve 230 is provided with a second annular lug 236, the outer diameter of the second annular lug 236 is larger than the inner diameter of the first annular lug and smaller than the inner diameter of the medicine sleeve 230, the second annular lug 236 is limited between the first annular lug 228 and the first end face of the hand sleeve 210, the first annular lug 228 and the first end face of the hand sleeve 210 is provided with a ratchet hole, that is provided with a preset distance between the first annular lug 228 and the first end of the push rod sleeve 230, namely the push rod sleeve can slide in the hand sleeve 230. In addition, the first annular protrusion 228 is provided with a notch 229, and a protruding rib 232 is disposed on the outer wall surface of the push rod sleeve 230 corresponding to the notch 229, so that when the second annular protrusion 236 is fixedly limited between the inner end surface of the first end of the handheld sleeve 210 and the first annular protrusion 228, the protruding rib 232 is just located in the notch 229, and the rotation freedom degree of the push rod sleeve 230 is limited, so that the push rod sleeve 230 can only slide within a preset distance length in the medicine compartment sleeve 220 and cannot rotate. The pre-tightening spring 600 is sleeved outside the push rod body 310 of the push rod 300, and one end of the pre-tightening spring 600 abuts against the third annular protrusion 235 on the inner wall of the push rod sleeve 230, and the other end of the pre-tightening spring 600 abuts against the inner wall of the first end face of the handheld sleeve 210, so that the push rod sleeve 230 keeps the second annular protrusion 236 abutting against the first annular protrusion 228 under the pre-tightening force of the pre-tightening spring 600. In addition, a first end surface of the push rod sleeve 230 is provided with a first ratchet 234, a second end surface of the push rod sleeve 230 can extend into the medicine compartment 100, and an inner wall of the first end surface of the first end of the hand-held sleeve 210 is provided with a second ratchet 204 matched with the first ratchet 234. When the connection structure 200 is not connected with the medicine compartment 100, the third annular protrusion 235 of the push rod sleeve 230 keeps the second annular protrusion 236 abutting against the first annular protrusion 228 under the pre-tightening force of the pre-tightening spring 600, and a certain distance is kept between the first ratchet 234 at the first end of the push rod sleeve 230 and the second ratchet 204 of the hand-held sleeve 210, at this time, because the hand-held sleeve 210 is in threaded connection with the medicine compartment sleeve 220, the hand-held sleeve 210 and the medicine compartment sleeve 220 can be separated or installed by rotation.
When the connection structure 200 is connected with the medicine bin 100 provided with the medicine bottle 400, as the diameter of the outer wall of the push rod sleeve 230 of the booster is smaller than that of the inner wall of the medicine bin 100, the push rod sleeve 230 can extend into the medicine bin 100 in the installation process of the connection structure 200 and the medicine bin 100, the second end surface of the second end of the push rod sleeve 230 is preferably just abutted against the first end surface of the first end of the medicine bottle 400 (the first end of the medicine bottle 400 refers to one end with the movable rubber plug 420), and along with the matched connection process of the first buckle structure of the medicine bin sleeve 220 of the connection structure 200 and the second buckle structure of the medicine bin 100, the connection structure 200 can gradually approach and realize matched connection with the medicine bin 100, the push rod sleeve 230 is gradually extruded by the medicine bottle 400 to overcome the pretightening force of the pretightening spring 600, and finally, if the hand-held sleeve 210 is in threaded connection with the medicine bin sleeve 220, and the first ratchet 234 and the second ratchet 204 are in threaded connection with the medicine bin 220, and the medicine bin 220 can be just limited by the direction of the medicine bin 220 can be rotated when the medicine bin 100 is just one time, and the medicine bin 220 is not screwed into the medicine bin 100 is just limited, and the direction of the medicine bin is just can be rotated, and the medicine bin is prevented from being screwed into the medicine bin 100.
When the connection structure 200 is connected with the medicine bin 100 without the medicine bottle 400, the third annular protrusion 235 of the push rod sleeve 230 still keeps the second annular protrusion 236 to abut against the first annular protrusion 228 under the pretightening force of the pretightening spring 600 because the push rod sleeve 230 is not extruded by the medicine bottle 400, a certain distance is still kept between the first ratchet 234 at the first end of the push rod sleeve 230 and the second ratchet 204 of the hand sleeve 210, at this time, since the hand sleeve 210 is in threaded connection with the medicine bin sleeve 220, the hand sleeve 210 and the medicine bin sleeve 220 can be separated by rotation, after the periphery protection of the hand sleeve 210 is lost by the medicine bin sleeve 220, the ratchet hole serving as the first buckle structure on the medicine bin sleeve 220 is exposed, at this time, the second buckle structure ratchet matched and connected with the ratchet hole can be manually disconnected, and then the medicine bin sleeve 220 can be separated from the medicine bin 100, and the hand sleeve 210 is in threaded connection with the medicine bin sleeve 220, thus the separation of the connection structure 200 and the medicine bin 100 is realized. Therefore, when the medicine container 100 is not mounted with the medicine bottle 400, the connecting structure 200 is detachable after being connected with the medicine container 100, so as to avoid the waste caused by connecting the medicine container 100 with the connecting structure 200 by mistake when the medicine bottle 400 is not mounted into the medicine container 100.
