Description
Technical field
The present invention relates to laboratory equipment technical field, especially a kind of sucker structure of experiment equipment.
Background technology
With the high speed development of Chinese society, science and technology is also maked rapid progress therewith, deep to the research of biology at present
Enter to molecular level.The problem of many scientific research personnel can encounter the following aspects when being loaded indoors to centrifuge tube：
In experimentation, knocks over or fall since tube sheet will be centrifuged accidentally, the centrifuge tube sample that do not close in time is caused to spill, it is above-mentioned
Phenomenon not only causes the consumption in time and efforts, while can cause the waste of test specimen, reagent and consumptive material, while after being also
Continuous being smoothed out for experiment brings inconvenience.
Invention content
The technical problem to be solved by the present invention is to：A kind of sucker of the experiment equipment of of simple structure and strong practicability is provided
Structure, with overcome the deficiencies in the prior art.
The invention is realized in this way：
A kind of sucker structure of experiment equipment, including rubber suction cups, which is horn-like structure, in rubber suction cups
Venthole is set in top, is fixedly connected and is connected to venthole, connecting shaft at the top of flexible snorkel and rubber suction cups
It is inserted into flexible snorkel and is interference fit with snorkel, plastics air relief cock is fixedly installed in the middle part of connecting shaft,
Gas vent is arranged in plastics air relief cock both sides, which coordinates with flexible snorkel.
In a kind of sucker structure of experiment equipment above-mentioned, it is arranged above button in connecting shaft, spring pocket is in connecting shaft
Upper and its upper and lower side is held out against with button and plastics air relief cock respectively.
It is cone structure, modeling in a kind of sucker structure of experiment equipment above-mentioned, at the top of the flexible snorkel
Material air relief cock is placed on the top of snorkel.
In a kind of sucker structure of experiment equipment above-mentioned, fixed frame is set to realize in flexible snorkel both sides
It is connected as entirety with experiment equipment.
By adopting the above-described technical solution, compared with prior art, the present invention utilizes the principle of negative pressure realization pair of sucker
The absorption of experiment equipment is interference fitted by flexible snorkel and connecting shaft, is realized during to pushing, and rubber is inhaled
Internal gas is discharged disk from surrounding, then atmospheric pressure realizes the fixation to rubber suction cups, is to pass through button pressed downwards when needing to unclamp
Connecting shaft moves down simultaneously with the fixed plastics air relief cock of connecting shaft, and since snorkel has elasticity, then plastics air relief cock is moving down
Ventilation bore is amplified in the process, then forms gap, gas vent stream of the air from air relief cock both sides between connecting shaft and snorkel
Enter in snorkel and flow ultimately into sucker, when atmospheric pressure is consistent inside and outside sucker, then easily takes down sucker, the present invention
It is simple in structure, it is easy to make, it is highly practical.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the present invention；
Attached drawing 2 is the structural schematic diagram of plastics air relief cock in the present invention.
Specific implementation mode
The embodiment of the present invention：A kind of sucker structure of experiment equipment, including rubber suction cups 1, it is characterised in that：The rubber
Sucker 1 is horn-like structure, venthole 2 is arranged in 1 top of rubber suction cups, flexible snorkel 3 is pushed up with rubber suction cups 1
Portion is fixedly connected and is connected to venthole 2, and connecting shaft 4 is inserted into flexible snorkel 3 and is matched for interference with snorkel 3
It closes, in 4 middle part fixed setting plastics air relief cock 5 of connecting shaft, gas vent 6, the plastics air relief cock is set in 5 both sides of plastics air relief cock
5 coordinate with flexible snorkel 3.
Wherein be arranged above button 7 in connecting shaft 4, spring 8 be sleeved in connecting shaft 4 and its upper and lower side respectively with button 7
It is held out against with plastics air relief cock 5, which is cone structure, and plastics air relief cock 5 is placed on snorkel 3
Top, 3 both sides of flexible snorkel be arranged fixed frame 9 with realize with experiment equipment be connected as entirety.
When specific making uses
The present embodiment by plastic button, plastics connecting shaft, spring, plastics air relief cock, top be rubber plastic ventilation pipe,
Rubber suction cups forms；Spring, plastics air relief cock are fixed to by buckle or screw in plastics connecting shaft；Plastics connecting shaft bottom
The plastic ventilation pipe that top is rubber is stretched into, blocking action is played to the plastic ventilation pipe that top is rubber；This centrifugation tube sheet exists
In use, force main board plate face with certain, the rubber suction cups gas of sucker component passes through the plastic ventilation that top is rubber
Pipe discharge upwards, is decontroled when the rubber pad of main board bottom four corners touches testing stand, is centrifuged tube sheet in this way and is just firmly glued
It, will not be because being not intended to fall due to collision on experimental bench；In mobile centrifugation tube sheet, flicking is deflated by plastic button, plastics
Plug also moves downward therewith, and when reaching certain position, top is that the plastic ventilation pipe of rubber is slightly softened, and gas passes through plastics
Stomata on air relief cock enters the plastic ventilation pipe that top is rubber, and rubber suction cups loses suction-operated and leaves desktop.
The description of said program is the invention being intended to facilitate those of ordinary skill in the art to understand and use.It is familiar with
The personnel of art technology obviously easily can make various modifications to embodiment.Therefore, the present invention is not limited to above-mentioned realities
Scheme, those skilled in the art according to the method for the present invention, all should by improvement and modification made without departing from the scope of the present invention
Within protection scope of the present invention.
