Abstract

The utility model relates to a chemistry drainage stick belongs to teaching articles for use technical field. Including drainage stick body, drainage stick body includes barred body and barred body down, and the cross section of going up the barred body is the cylinder type, the cross section semicircular in shape of lower barred body, and the rubber suction cups is installed at the top of going up the barred body, and the below of rubber suction cups is equipped with the flourishing flange of dish form, on flourishing flange is fixed in the outer wall of barred body, the opening direction of flourishing flange and the opening opposite direction of rubber suction cups, the external diameter of containing the flange is less than the external diameter of rubber suction cups. The utility model discloses structural design is ingenious, long service life, and the drainage is effectual, is difficult for causing the pollution after the use is accomplished.

Description

A kind of chemistry conduction stick

Technical field

This utility model relates to a kind of chemistry conduction stick, belongs to realia technical field of structures.

Background technology

Process of general chemistry teaching to carry out chemical experiment, conduction stick is experimental apparatus conventional in chemical experiment process, and existing conduction stick structural design is single, is only made up of cylindrical barred body, column type conduction stick is primarily present following shortcoming: 1, drainage effect is not good, and liquid is easily outer to be spattered; 2, cylindrical, it is easy to drop, frangible; 3, after having used, the liquid on conduction stick easily flows backwards, and pollutes.

Summary of the invention;

The purpose of this utility model is in that to solve the weak point that prior art exists, it is provided that a kind of smart structural design, long service life, drainage effect is good, the chemical conduction stick not easily polluted after having used.

This utility model is achieved through the following technical solutions:

A kind of chemistry conduction stick, it is characterized in that and includes conduction stick body, conduction stick body includes barred body 1 and lower barred body 2, the cross section of upper barred body 1 is column type, the cross section semicircular in shape of lower barred body 2, and the top of upper barred body 1 is provided with rubber suction cups 3, rubber suction cups 3 be connected with disk like access dish 4, access dish 4 is fixed on the outer wall of barred body 1, and the opening direction of access dish 4 is contrary with the opening direction of rubber suction cups 3, and the external diameter of access dish 4 is less than the external diameter of rubber suction cups 3;

Described rubber suction cups 3 is provided with the external diameter of socket pipe 5, the internal diameter of socket pipe 5 and upper barred body 1 and matches near one end of upper barred body 1;

The length of described upper barred body 1 is less than the length of lower barred body 2.

A kind of chemistry conduction stick of the present utility model, smart structural design, during use, can by chemical liquid down on lower barred body, chemical liquid flow in beaker along lower barred body, prevent chemical liquid excessive, after use completes, conduction stick body can be inverted, by rubber suction cups, conduction stick body is fixed on desktop, liquid on conduction stick body can be dirty, dirty chemical liquids is caught by disk like access dish, prevent chemical liquids from flowing on desk or flow on rubber suction cups, owing to the cross section of upper barred body is cylindrical, the cross section of lower barred body is semi-circular, therefore can prevent from tumbling to broken on the ground, improve service life. in sum, chemistry conduction stick smart structural design of the present utility model, very practical.

Accompanying drawing explanation

Fig. 1: the structural representation of this utility model a kind of chemistry conduction stick.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment 1

A kind of chemistry conduction stick of the present embodiment, it is characterized in that and includes conduction stick body, conduction stick body includes barred body 1 and lower barred body 2, the cross section of upper barred body 1 is column type, the cross section semicircular in shape of lower barred body 2, and the top of upper barred body 1 is provided with rubber suction cups 3, rubber suction cups 3 be connected with disk like access dish 4, access dish 4 is fixed on the outer wall of barred body 1, and the opening direction of access dish 4 is contrary with the opening direction of rubber suction cups 3, and the external diameter of access dish 4 is less than the external diameter of rubber suction cups 3; Rubber suction cups 3 is provided with the external diameter of socket pipe 5, the internal diameter of socket pipe 5 and upper barred body 1 and matches near one end of upper barred body 1; The length of upper barred body 1 is less than the length of lower barred body 2.

During use, can by chemical liquid down on lower barred body 2, chemical liquid flow in beaker along lower barred body 2, prevent chemical liquid excessive, after use completes, conduction stick body can be inverted, by rubber suction cups 3, conduction stick body is fixed on desktop, liquid on conduction stick body can be dirty, dirty chemical liquids is caught by disk like access dish 4, prevent chemical liquids from flowing on desk or flow on rubber suction cups 3, owing to the cross section of upper barred body 1 is cylindrical, the cross section of lower barred body 2 is semi-circular, therefore can prevent from tumbling to broken on the ground, improve service life.

It is only preferred embodiment of the present utility model described in upper, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
