Abstract
The utility model relates to a diameter-variable plug characterized by comprising a top sleeve, a moving plug, a rotating shaft, and a flexible sleeve pipe, wherein the top sleeve is provided with a feed hole therein, an upper end of the top sleeve is provided with a through hole communicated with the feed hole; the moving plug comprises a guide rod, a lower end of the guide rod is provided with a blocking shoulder, and an upper end of the guide rod is provided with a screwed hole; the rotating shaft comprises a shaft body, a lower end of the shaft body is provided with a screw; the guide rod of the moving plug is slidingly sleeved in the feed hole of the top sleeve, the flexible sleeve pipe is sleeved on the guide rod of the moving plug and abutted between the blocking shoulder of the moving plug and the top sleeve; and the screw of the rotating shaft is screwedly connected with the moving plug by passing through the through hole of the top sleeve, the shaft body is abutted against a top surface of the top sleeve. The diameter-variable plug of the utility model has the advantages of simple structure and convenient use; in addition, by rotating a handle, the diameter-variable plug can be conveniently plugged in and pulled out from an orifice or a container mouth needing to be sealed, and operations for plugging in and pulling out the diameter-variable plug are convenient and time-saving, thereby raising detection efficiency and achieving good sealing performance.
Description
Technical field
The utility model relates to the technological equipment that a kind of medicine equipment is produced, and especially relates to a kind of reducing stopper, is used for the auxiliary leak-testing of accomplishing nutrient bag.
Background technology
The leak-testing technology of nutrient bag is the technology of the air-tightness of one online detection nutrient bag; Before leak-testing, need liquid inlet sealing with nutrient bag; Charge into quantitative air then, finally judge the quality of the air-tightness of nutrient bag according to the force value in the nutrient bag.The common stopper of the many employings of the liquid inlet of nutrient bag sealing at present; Because internal pressure is bigger, stopper voluntarily from the liquid inlet ejection of nutrient bag, so directly causes once testing and need repeat repeatedly to install stopper and could accomplish in the test process of being everlasting; Waste time and energy, detection efficiency is low.
The utility model content
The applicant has carried out research and has improved to above-mentioned problem, and a kind of reducing stopper is provided, and good airproof performance, jam-pack are extracted easy to operate saving time, and improve detection efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of reducing stopper comprises top cover, moving plug, revolves axle and flexible sleeve, is provided with guide hole in the cover of said top, and the upper end of top cover is provided with the through hole that is communicated with said guide hole; Said moving plug comprises guide rod, and the lower end of guide rod is provided with shoulder block, and the upper end of guide rod is provided with threaded hole; The said axle that revolves comprises axis body, and the axis body lower end is provided with screw rod; The guide rod of said moving plug slides in the guide hole of said top cover, between flexible sleeve is sleeved on the guide rod of said moving plug and the shoulder block that is against said moving plug overlaps with said top; The said screw rod that revolves axle passes the through hole whorl that said top puts and connects said moving plug, and axis body leans on the end face of said top cover.
Further:
The said axis body that revolves axle is provided with handle.
Said flexible sleeve is processed by rubber or plastics.
Said threaded hole is a blind hole.
The technique effect of the utility model is:
The disclosed a kind of reducing stopper of the utility model, simple in structure, easy to use, through turning handle, easily jam-pack with extract the mouth of pipe or the vessel port that needs sealing, jam-pack with extract easy to operate saving time, improve detection efficiency, simultaneously good airproof performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
As shown in Figure 1, the utility model comprises top cover 2, moving plug 1, revolves axle 3 and flexible sleeve 4, is provided with guide hole 22 in the top cover 2, and the upper end of top cover 2 is provided with the through hole 21 that is communicated with guide hole 22; Moving plug 1 comprises guide rod 11, and the lower end of guide rod 11 is provided with shoulder block 12, and the upper end of guide rod 11 is provided with threaded hole 13, and threaded hole 13 is a blind hole; Revolve axle 3 and comprise axis body 32, axis body 32 lower ends are provided with screw rod 31, and the axis body 32 that revolves axle 3 is provided with handle 5; The guide rod 11 of moving plug 1 slides in the guide hole 22 that pushes up cover 2, is the guiding that moves up and down of moving plug 1 by guide hole 22, and flexible sleeve 4 is sleeved on the guide rod 11 that moves plug 1 and is against shoulder block 12 and the top of moving plug 1 and overlaps between 2, and flexible sleeve 4 is processed by rubber or plastics; The screw rod 31 that revolves axle 3 passes the through hole 21 that overlaps on 2 on the top and is threaded with moving plug 1, and axis body 32 leans on the end face of top cover 2.
In use; Put into the mouth of pipe or the vessel port that needs sealing to the shoulder block 12 of moving plug 1 and flexible sleeve 4 earlier; Rotary handle 5 makes screw rod 31 drive moving plug 1 and moves up; At this moment flexible sleeve 4 becomes greatly because of the shoulder block 12 that receives moving plug 1 extruding force with top cover 2 gradually, until with the mouth of pipe or the complete jam-pack of vessel port; When joystick 5 opposite spins, screw rod 31 will drive moving plug 1 and move down gradually, and the extruding force on the flexible sleeve 4 disappears and restores to the original state; So just can accomplish quick jam-pack and extract cock body, reach the purpose of save operation time, improve detection efficiency.
