Abstract
The utility model relates to a special-purpose hasp piston hole of a separating funnel which can effectively prevent the piston hole of the separating funnel from adhering, loosening to be dropped or disordering to be lost during the storing period in the operation processes of extracting, separating or purifying. The special-purpose hasp piston hole mainly comprises a standard piston (1) with a hasp, a hasp (2), a groove (3), a standard grinding hole (4) with a locking notch, a crimping (5), a locking notch (6), a vent hole (7) and an extraction chamber (8). The utility model is characterized in that the top portion of the standard piston (1) with a hasp is provided with the hasp (2), the crimping (5) is provided with the locking notch (6), the hasp (2) is inserted from the hasp (2), and the hasp (2) leads the standard piston (1) with a hasp to be tightly matched with the standard grinding hole (4) with a locking notch, thereby effectively preventing a grinding-hole piston from loosening and loosing.
Description
Technical field
The utility model belong to a kind of from solution the extraction, certain composition of isolated or purified, or in the operating process of reaction, add the special-purpose snap close plug mouth of the separatory funnel of liquid, it be applicable to universities and colleges, scientific research, medicine and industrial and mining enterprise unit laboratory and laboratory extraction, separate, purifying or compound experiment.
Background technology
Separatory funnel in the existing technology when operation, will be held funnel filling opening neck with the right hand earlier, and forefinger compresses the funnel grinding port plug, and left hand is held in funnel piston place, and the thumb clamping piston is set level vibration to separatory funnel then.Behind the vibration certain hour, downward-sloping the separatory funnel grinding port plug, the filler neck points upwards, left index finger and thumb cooperate opens the piston venting.At last again with the separatory funnel frame on iron ring, open the grinding port plug on the separatory funnel, separating liquid.This separatory funnel troublesome poeration requires highly, careless slightly will be because of grinding port plug lax or come off and cause the failure of an experiment to operating technology, even cause the injury to the operator.In addition, separatory funnel of the prior art the grinding port plug adhesion usually can occur, come off and lose and chaotic phenomenon in the process of depositing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of can preventing effectively to come off in that the operating process grinding port plug is lax, or the special-purpose snap close plug of the separatory funnel mouth lost of grinding port plug adhesion during storage, confusion.
The technical scheme that its technical problem that solves the utility model adopts is: the special-purpose snap close plug of separatory funnel mouth, mainly form by tool snap close standard plug (1), snap close (2), groove (3), tool fore shaft standard ground (4), crimping (5), fore shaft (6), passage (7) and extraction cell (8); It is characterized in that: a snap close (2) is arranged at the top of tool snap close standard plug (1), and a groove (3) is arranged at the bottom; The upper edge hole of tool fore shaft standard ground (4) has a circle uniform crimping (5), and a fore shaft (6) is arranged on the crimping (5); Snap close (2) inserts from fore shaft (6), and after the rotation, the latch hook of snap close (2) just tightly fastens the lower edge of crimping (5), makes tool snap close standard plug (1) and tool fore shaft standard ground (4) close proximity; There is a passage (7) at the middle part of tool fore shaft standard ground (4), and the neck of tool fore shaft standard ground (4) bottom and extraction cell (8) welds together.
In conjunction with above summary of the invention as can be seen, the utility model has following advantage compared to existing technology:
(1) because tool snap close standard plug (1) has adopted snap close (2) design, using and depositing in the process, snap close (2) tightly is locked in the lower edge of crimping (5), tool snap close standard plug (1) tightly is fixed in the tool fore shaft standard ground (4), thereby prevented effectively in the extract and separate operating process, or the grinding port plug phenomenon that relaxes, come off or lose during storage.
(2) because snap close (2) on the tool snap close standard plug (1) and groove (3) design on same vertical line, snap close (2) protrudes in tool snap close standard plug (1) dome, is projective structure, just in time the sign mark that cooperates with passage (7) position as groove (3).When so just making separating liquid, point to passage (7) position, neither must open wide tool fore shaft standard ground (4), must not search passage (7) position again specially, made things convenient for operation widely as long as snap close (2) is protruded sign.
