The two sides of the outer rod are connected with two vertical rods through first connecting rods inclined upwards, the two ends of the inner rod are connected with the two vertical rods through second connecting rods inclined downwards, rotating shafts are arranged at the joints of the first connecting rods and the outer rod and the joints of the first connecting rods and the vertical rods respectively, rotating shafts are arranged at the joints of the second connecting rods and the inner rod and the joints of the second connecting rods and the vertical rods respectively, and cleaning brush bristles are evenly arranged on the outer side walls of the vertical rods. Compared with the prior art, the test tube cleaning device for the chemical experiments has the advantages of being reasonable in design, simple in structure, convenient to use and adjust, suitable for test tubes of different specifications, and wide in application range.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, specifically a kind of easy to use, chemical experiment test tube cleaning device.
Background technology
Chemical experiment in school is indoor, and test tube is used widely, test tube, and the instrument that chemical laboratory is conventional, can directly heat, and serves as the reaction vessel of a small amount of reagent.It is multiple that test tube divides common test tube, tool props up test tube, centrifuge tube etc.The specification of common test tube represents with external diameter (mm) × length (mm), as 15 × 150,18 × 180,20 × 200 etc., and the clean general of test tube adopts simple cleaning brush to complete, existing cleaning brush structure is single fixing, can only be applicable to a kind of test tube of size, practicality is not strong.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of chemical experiment simple in structure, easy to use test tube cleaning device is provided.
The technical solution of the utility model realizes in the following manner, this one chemical experiment test tube cleaning device, its structure comprises expansion link, this expansion link is by outer bar, be slidably socketed the interior bar composition of bar inner side outside, described outer bar both sides are all connected with two vertical rods by acclivitous head rod, interior bar both sides all connect above-mentioned two vertical rods by the second downward-sloping connecting rod, this head rod respectively with outer bar, the junction of vertical rod is provided with rotating shaft, the second connecting rod respectively with interior bar, the junction of vertical rod is provided with rotating shaft, on the lateral wall of described vertical rod, be evenly provided with clean bristle.In this technical scheme, head rod, the second connecting rod are all rotationally connected with vertical rod, head rod and the second connecting rod incline direction are just the opposite, like this in the time of stretching expansion link, just can complete the adjusting to distance between vertical rod and expansion link by head rod, the second connecting rod, and then meet the test tube demand of different size.
As preferably, described vertical rod downside is connected with the bent rod of making to the bending of expansion link direction, rubber, is evenly provided with clean bristle on the lateral wall of this bent rod.The setting of this structure is enough clean clean in order to guarantee test tube two bottom sides wall energy, and the bent rod that rubber is made guarantees that elasticity is larger, applied widely.
As preferably, described expansion link bottom is provided with the spherical bar of being made up of rubber, is evenly provided with clean bristle on the lateral wall of this spherical bar.The setting of this structure is can clean totally bottom embassy in order to guarantee, guarantees the clean dead angle of not staying.
As preferably, the upper end of described expansion link is provided with swing handle.The swing handle of this structure is in order to guarantee the easy to use of expansion link.
Further, described swing handle is " U " shape flat.The convenient gripping of swing handle of this structure.
The beneficial effect that the utility model compared with prior art produced is:
A kind of chemical experiment of the present utility model with test tube cleaning device have simple in structure, easy to use, the feature such as be skillfully constructed, by the distance between adjustable telescopic rod and vertical rod, be applicable to the cleaning of the test tube of different size, guarantee cleaning effect, do not stay dead angle, flexibility is good, designs hommization more, practical, be easy to promote the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is swing handle structural representations of the present utility model.
Mark in accompanying drawing represents respectively:
1, swing handle, 2, expansion link, 2.1, interior bar, 2.2, outer bar, 3, rotating shaft, 4, clean bristle, 5, bent rod, 6, spherical bar, 7, head rod, 8, vertical rod, 9, the second connecting rod.
The specific embodiment
Below in conjunction with accompanying drawing, a kind of chemical experiment of the present utility model is described in detail below with test tube cleaning device.
As accompanying drawing 1, shown in Fig. 2, this one chemical experiment test tube cleaning device, its structure comprises expansion link 2, this expansion link 2 is by outer bar 2.2, being slidably socketed the interior bar 2.1 of bar 2.2 inner sides outside forms, described outer bar 2.2 both sides are all connected with two vertical rods 8 by acclivitous head rod 7, interior bar 2.1 both sides all connect above-mentioned two vertical rods 8 by the second downward-sloping connecting rod 9, this head rod 7 respectively with outer bar 2.2, the junction of vertical rod 8 is provided with rotating shaft 3, the second connecting rod 9 respectively with interior bar 2.1, the junction of vertical rod 8 is provided with rotating shaft 3, like this, between head rod 7 and outer bar 2.2, can realize relative rotation, between head rod 7 and vertical rod 8, can realize relative rotation, between the second connecting rod 9 and interior bar 2.1, can realize relative rotation, between the second connecting rod 9 and vertical rod 8, can realize relative rotation, on the lateral wall of described vertical rod 8, be evenly provided with clean bristle 4.
Described vertical rod 8 downsides are connected with the bent rod 5 of making to expansion link 2 direction bendings, rubber, are evenly provided with clean bristle 4 on the lateral wall of this bent rod 5.
Described expansion link 2 bottoms are provided with the spherical bar 6 of being made up of rubber, namely the bottom of bar 2.2 arranges spherical bar 6 outside, mode and outer bar 2.2 that this spherical bar 6 can be threaded connection are connected and fixed, and are evenly provided with clean bristle 4 on the lateral wall of this spherical bar 6.The upper end of described expansion link 2 is provided with swing handle 1, namely connects this swing handle 1 in the upper end of interior bar 2.1, and its connected mode can adopt and be threaded.Described swing handle 1 is " U " shape flat, and its U-shaped bottom is connected with the top of interior bar 2.1.
