Description
Technical field
The present invention relates to a kind of energy-conserving and environment-protective and make field of experiment equipment, particularly a kind of waste or used plastics makes method and the application thereof of ear washing bulb pressure fine-adjustment device.
Background technology
The application of ear washing bulb is very wide.Because its practicality is good, draw materials conveniently, make simple, be widely used in the fields such as chemistry, medical and health, engineering.But existing ear washing bulb is comparatively large because of its impact by human factor, can not accurately complete experimental implementation.Often because manual operation is improper, causing when pipetting or drip liquid, cannot accurately control.Such as we are in the experiment of laboratory measurement surface tension of liquid, and when using ear washing bulb to carry out dropping liquid operation, find to use original ear washing bulb not meet requirement of experiment, error is too large, even can cause the failure of an experiment.
In order to improve to pipette liquid volume control stability and accuracy, we must transform original ear washing bulb, are intended to design a kind of stable operation and the good pipette device of controllability.Many patents are improved the outward appearance of traditional ear washing bulb, such as CN302995235S and CN302995238S, but fundamentally could not solve the unstability of ear washing bulb for existing when a small amount of or micro liquid pipette; CN204034734U discloses a kind of convenient controlled easy cleaning pipette, overcome the difficulty of pipette difficulty cleaning, the amount of solution absorption can be controlled by push-and-pull rubber piston simultaneously, but operating personnel's initiative when push-and-pull rubber piston is very strong,, still there is very large destabilizing factor in bad control push-and-pull degree.Therefore, invent a kind of pressure fine-adjustment device that accurately can control micro liquid pipette to be necessary very much.In addition, due to the applicable field of pressure fine-adjustment device widely, to be easy to get and with low cost so require to make simple, raw material.
Summary of the invention
The object of this invention is to provide a kind of factures and applicationsh of the ear washing bulb pressure fine-adjustment device utilizing waste or used plastics to make.
For achieving the above object, the present invention takes following technical scheme: circular hole is opened in center, two of housing relative faces, and a hole just makes the proboscis of ear washing bulb pass through, and another hole just in time makes to pass with the bolt of protective sleeve; The shallow slot of nut shape is polished, with glue hold-down nut outside the circular hole of bolt end.
The material of described making housing comprises lucite and waste or used plastics Package casing or waste and old disposable plastic articles for use, not only makes simple and convenient, and with low cost, energy-conserving and environment-protective.
Described ear washing bulb can with ear washing bulb most of on market, and concrete specification housing size according to claim 2 carries out choose reasonable.
Described protective sleeve is contained in the head (with ear washing bulb contact position) of bolt, slows down the friction of bolt to ear washing bulb; In addition, also can fill a protective sleeve at bolt tail, extenuate the friction of hand and nut when operating personnel operate.
The rubber glue head of bore and bolt matching selected by described protective sleeve, also can select and can be wrapped in plastics on bolt head and tail or other materials.
Application during described ear washing bulb pressure fine-adjustment device pipettes about micro liquid or drips or control in laboratory and medical treatment.
Ear washing bulb pressure fine-adjustment device of the present invention has the following advantages:
1. this ear washing bulb pressure fine-adjustment device of designing and producing of the present invention, carry out in the lab micro liquid pipette and surface tension test time, slowly promote extruding dynamics by rotary screw, slowly extrude ear washing bulb afterbody by the hemispherical protective sleeve at screw top.The cause of coping screw thread turns, nut often rotates a circle, one section that advance distance is just very little, and compared with the mode of our manual control, operation is more accurate, more stable, and reduces the error that manual operation brings as much as possible.
2. ear washing bulb pressure fine-adjustment device of the present invention can also use in many other occasions, such as chemically examines, the aspect such as quarantine.
3. ear washing bulb pressure fine-adjustment device of the present invention accurately controls the suction discharge rate of liquid by the rotation of screw, and air-tightness is good, little by external interference, and structure is simple, and easy to operate, volume is little to be easy to carry.
4. apparatus of the present invention have drawn from waste or used plastics, with low cost, easy to make, from the angle of environmental protection and waste reclamation, meet the requirement of Green Chemistry.
