Description
Technical field
The utility model relate to a kind of flask cleaning brush.
Background technology
In laboratory, the normal cleaning means such as test-tube brush that use clean glassware, but the most structure of existing test-tube brush is simple.The vessel that experiment uses are not of uniform size, and single brush is not suitable for cleaning multiple vessel.Conventional brush is generally unshielded, is directly exposed in air, easily overstocks dust etc.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides the flask cleaning brush that a kind of structure is simple, easy to use.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of flask cleaning brush, it comprises pressing handle, glue brush, catch bar, glue brush retracts the brush holder pipe of pipe and upper and lower opening, described catch bar is located in described brush holder pipe, the lower end of described catch bar is arranged with spring, the sheathed described pressing handle in upper end of described catch bar, described pressing handle is the sleeve pipe of one end open, the openend of described pressing handle is set in described brush holder pipe, the diameter of the openend of described pressing handle is greater than the diameter of the upper shed of described brush holder pipe, the diameter of described spring is greater than the diameter of the under shed of described brush holder pipe, described brush holder pipe has some spacing holes, and described catch bar is provided with a spring retainer button, described glue brush is arranged on described glue brush and retracts in pipe, and described glue brush retracts pipe and is communicated with described brush holder pipe, and the lower end being located at described catch bar is twisted in the upper end of described glue brush.
Based on above-mentioned, the lower end of described catch bar is twisted and is provided with two glue brushes, is connected with spring between two glue brushes.Described main frame MCU, analyzes the first phase that described synchronizing signal obtains the first voltage and current, the first phase of comparison first voltage and current and the first phase of the second voltage and current, obtains in-phase signal when the two amplitude-phase is identical.
The utility model hinge structure has substantive distinguishing features and progress, and specifically, in the utility model, the extension elongation of glue brush can adjust as required, and when not using, glue brush takes in glue brush retracting pipe, prevents from exposing and overstocks dust in atmosphere.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state schematic diagram of the present utility model.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of flask cleaning brush, it comprises pressing handle 1, catch bar 2, glue brush retract pipe 3, the brush holder pipe 4 of upper and lower opening and glue brush 5,
Described catch bar 2 is located in described brush holder pipe 4, the lower end of described catch bar 2 is arranged with back-moving spring 6, the sheathed described pressing handle 1 in upper end of described catch bar 2, described pressing handle 1 is the sleeve pipe of one end open, the openend of described pressing handle 1 is set in described brush holder pipe 4, the diameter of the openend of described pressing handle 1 is greater than the diameter of the upper shed of described brush holder pipe 4, and the diameter of described back-moving spring 6 is greater than the diameter of the under shed of described brush holder pipe 4; Described brush holder pipe 4 has some spacing holes 7, and described catch bar 2 is provided with a spring retainer button 8; Described glue brush 5 is arranged on described glue brush and retracts in pipe 3, and described glue brush retracts pipe 3 and is communicated with described brush holder pipe 4, and the lower end being located at described catch bar 2 is twisted in the upper end of described glue brush 5.
In other embodiments, the lower end of described catch bar 2 is twisted and is provided with two glue brushes, is connected with spring 9 between two glue brushes.
When using, press described pressing handle 1, described catch bar 2 promotes downwards under the promotion of described pressing handle 1, the limited extruding of described spring 6, described glue brush is released described glue brush by 5 and is retractd outside pipe 3, when described spring retainer button 8 times is to first spacing hole, because spacing hole 7 is ejected in the effect of spring, releasing described glue brush 5 to continue, needing described spring retainer button 8 to press in inlet hole and press described pressing handle 1 simultaneously and make promotion enter next spacing hole; After finishing using, press described spring retainer button 8, described spring 6 restores to the original state, and drives described glue brush 5 to regain described glue brush and retracts pipe 3.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
