Bottle cap assembly

Abstract

The invention discloses a bottle cap assembly. The bottle cap assembly comprises a bottle cap, a pushing assembly and a rotating head, the bottle cap comprises a base and a threaded part, the threaded part is circumferentially arranged on the edge of the base, and the threaded part is used for threaded connection of the bottle cap to a reagent bottle; the pushing assembly comprises a transmission frame and a hanging plate, the transmission frame is arranged on the top face of the base around the rotating center line of the bottle cap, an area used for containing the rotating head to rotate is defined by the transmission frame, and the hanging plate is arranged at the top of the transmission frame and used for hanging the bottle cap on the rotating head; and the rotating head rotates in the area so as to drive the bottle cap to rotate. The threaded part and the pushing assembly are additionally arranged on the bottle cap, then the rotating head rotates in the area defined by the transmission frame of the pushing assembly, and then the rotating head drives the bottle cap to correspondingly rotate through the transmission frame, so that the threaded connection relation between the threaded part and the bottle opening of the reagent bottle is changed. Meanwhile, the bottle cap can be hung on the rotating head through the hanging plate, so that the purpose of effectively sealing and opening the reagent bottle is achieved.

Description

technical field [0001] The invention relates to the technical field of medical inspection, in particular to a bottle cap assembly. Background technique [0002] During the medical inspection process, the inspector needs to unscrew the bottle cap of the medical bottle, and then perform the action of sampling or adding liquid, and then close the bottle cap. Due to its low efficiency and high risk of biological contamination, manual unscrewing and closing of bottle caps cannot meet the needs of huge inspection workloads in medical hospitals, and the application of automated bottle cap opening and closing on medical inspection equipment is becoming more and more more and more. [0003] See the utility model patent CN213923979U, which discloses "a rotary head for protecting the anti-slip pattern of the plastic cap". The friction provided by the thread is not stable, and it is prone to problems of under-tightening and over-tightening. As a result, in the opening and closing deb...

Problems solved by technology

Due to its low efficiency and high risk of biological contamination, manual unscrewing and closing of bottle caps cannot meet the needs of huge inspection workloads in medical hospitals, and the application of automated bottle cap opening and closing on medical inspection equipment is becoming more and more more and more

[0003] See the utility model patent CN213923979U, which discloses "a rotary head for protecting the anti-slip pattern of the plastic cap". The friction provided by the thread is not stable, and it is prone to the problem of under-tightening and over-tightening

As a result, in the opening and closing debugging process of the actual bottle cap, it is necessary to control the degree of clamping of the bottle cap by the rotary head, the debugging time is long, it is not stable, and the after-sales maintenance pressure is high

At the same time, the peripheral diameter of the claw-type rotary head is larger than the diameter of the bottle cap, and the volume is relatively large, which cannot meet the requirements of equipment miniaturization, and the structure of the claws is relatively complicated, and the production cost is high.
