Abstract

The utility model provides a suction pipe, and relates to the technical field of laboratory appliances. The suction pipe comprises a suction pipe pole (1), a plastic suction head (2), and further comprises a bend pipe (8) for connecting the suction pipe pole (1) and the plastic suction head (2), wherein the opening part of one end of the bend pipe (8) is combined with the plastic suction head (2), and the opening part of the other end is connected with the large end of the suction pipe pole (1); when the suction pipe is adopted to perform the operation of transferring liquor, the mode of holding the suction pipe is changed from the mode like holding a writing brush to the mode of holding a pen due to the additionally arranged bend pipe; and the operation is more labor-saving and facilitates mastery of beginners.

Description

A kind of suction pipe
Technical field
The utility model relates to the laboratory Instrument technology field.
Background technology
In conjunction with Fig. 1, the laboratory namely is that common plastic cement suction nozzle 2 is installed in suction pipe 1 upper end when using the glass pasteur pipet, and the experimental work personnel suck liquid in the suction pipe 1 thereby make suction pipe and ambient atmosphere produce draught head with finger extruding plastic cement suction nozzle 2.When the staff operates, at first be to be undertaken spacingly by middle finger 5 and nameless 6 pairs of suction pipes 1, carry out liquid assimilating work by thumb 3 and forefinger extruding plastic cement suction nozzle 2 again.If long-time operation, it is tired that acid appears in thumb easily, thereby and the beginner also be not easy the effect that the influence of grasp dynamics moves liquid.
Summary of the invention
The invention technical problem to be solved provides a kind of easy to use and laboratory, labour-saving suction pipe.
The invention is for solving the problems of the technologies described above, by the following technical solutions:
A kind of suction pipe comprises suction pipe bar, plastic cement suction nozzle, also comprises the bend pipe that connects suction pipe bar and plastic cement suction nozzle, is combined with the plastic cement suction nozzle in bend pipe one end opening place, and other end opening part connects the big end of suction pipe bar.
Further, described bend pipe is set to U-shaped pipe.
Further, described bend pipe is long tube for one section, and one section is short tube.
Further, described long tube and short tube differ 2-5cm.
Further, the outside sheathed rubber sleeve in described bend pipe and the big end of suction pipe bar junction.
Owing to adopted technique scheme, the invention to have following beneficial effect:
The invention is by adding bend pipe between suction pipe bar and plastic cement suction nozzle, in the time of will adopting suction pipe to move liquid work, hand-held suction pipe becomes the mode of hand-held pen by similar mode of holding writing brush, and is more laborsaving and be convenient to the beginner and grasp.
Description of drawings
Fig. 1 is the schematic diagram of existing suction pipe application state;
Fig. 2 is the schematic diagram of the invention preferred embodiment suction pipe application state;
The specific embodiment
As Fig. 2, the suction pipe of present embodiment comprises suction pipe bar 1, plastic cement suction nozzle 2, also comprises the U-shaped bend pipe 8 that connects suction pipe bar 1 and plastic cement suction nozzle 2.U-shaped bend pipe is long tube for 8 one sections, and one section is short tube, and long tube and short tube differ 2-5cm; Long tube section and 2 combinations of plastic cement suction nozzle, short sections is connected the outside sheathed rubber sleeve 7 in both junctions with suction pipe bar 1 big end.
When the suction pipe of present embodiment moved liquid work, by thumb 3 and middle specific bit suction pipe forefinger 4, forefinger 4 extruding plastic cement suction nozzles 2 got final product, even long-time operation, pointing especially, thumb also is difficult for producing the tired sense of acid; And this hand finger grabbing type is convenient to beginner's grasp.
