Abstract
The utility model relates to one and turns over button syringe filters, its objective is to provide a kind of structure simple, easy to operate, the syringe-driven filter that operating efficiency is higher.The utility model comprises levels lid.Upper strata lid has annular groove, and lower floor's lid has annular tongue, tongue and groove close contact, and upper strata lid outer rim has four buckles, and lower floor's lid outer rim has four buckle junctors.This material of turning over button filter is polycarbonate plastic.It is simple that the utility model is mainly to make upper and lower lid connected mode, is convenient to change filter paper, saves the experimental implementation time, button and tongue and groove structure are turned in employing, and seal is good, and structure is simple, easy to use, having higher operational stability and this experimental provision of security can equipmentization produce.
Description
Technical field
The utility model relates to one and turns over button syringe filters.
Background technology
Syringe-driven filter is the common small sized instrument in laboratory.Conventional needle-based was crossed elimination and was made up of upper and lower two parts dome present stage, had to protrude arcuate thread and connect.During due to laboratory use syringe-driven filter, need frequently to change filter paper, screw-type filter uses loaded down with trivial details.Puzzlement is brought to experimental implementation
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides that a kind of structure is simple, button syringe filters is turned in operation easily.
To achieve these goals, the technical solution of the utility model is as follows:
This material of turning over button filter is polycarbonate plastic.Be made up of dome lid, dome lid is divided into upper strata lid (1) and lower floor's lid (2), upper strata lid (1) edge fluted (3) and four buckles (4), and lower floor's lid corresponding upper strata lid (3) groove has (6) tongue to have (5) buckle junctor.(3) (6) tongue and groove forms contact surface, and buckle blocks junctor, forms closed state.
This turns over, and fibula head filtration device structure is simple, easy to use, and button method is turned in employing makes upper and lower lid connect, and maintains filter interior filter space, improves replacing filter paper speed.
Accompanying drawing explanation
Fig. 1 is for turning over button syringe filters front view, and Fig. 2 is for turning over fibula head filter cover top view, and Fig. 3 is for turning over button syringe filters lower cover top view, and wherein 1 is upper cap body, and 2 is lower cap body, and 3 is annular groove, and 4 is buckle, and 5 is buckle junctor, and 6 is annular tongue.
Detailed description of the invention
With reference to accompanying drawing, this kind turns over button syringe filters, includes upper strata lid 1 and lower floor's lid 2, and upper strata lid and lower floor's lid form closed state.Embodiment one, when solution needs to filter, after lower floor's lid places filter membrane, with upper strata cover cap levels lid, the tongue and groove of upper and lower lid links closely together, and outside four buckles are firmly buckled on buckle junctor, make whole lid good seal.Then extract solution with syringe needle, by lid injection out, filtered.After filtration, open buckle, open upper strata lid, change filter membrane, repeat above-mentioned action.
