Abstract
The utility model provides a flask cleaning brush for chemical experiments. The flask cleaning brush structurally comprises an adjusting tube and an adjusting cap, wherein the upper end of the adjusting tube is open, the lower end of the adjusting tube is closed, and the adjusting cap is installed on the adjusting tube in a sliding mode. The adjusting cap is of a barrel shape, an adjusting rod capable of stretching into the adjusting tube through an adjusting mechanism is arranged at the center of the adjusting cap, the adjusting mechanism comprises a plurality of circular-truncated-cone-shaped limiting teeth and circular-truncated-cone-shaped limiting grooves, wherein the circular-truncated-cone-shaped limiting teeth are sequentially connected, the upper portion of each circular-truncated-cone-shaped limiting tooth is larger than the lower portion of the circular-truncated-cone-shaped limiting tooth, and the circular-truncated-cone-shaped limiting grooves are formed in the inner wall of the adjusting tube and matched with the limiting teeth for use. Hairbrushes are arranged at the front end of the adjusting rod, and hairbrush outlets are formed in the side wall of the front of the adjusting tube and matched with the hairbrushes for use. Compared with the prior art, the flask cleaning brush for the chemical experiments has the advantages of being reasonable in design, simple in structure, convenient to use and adjust, high in practicability, 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 flask cleaning brush.
Background technology
Chemical experiment in school is indoor, flask is used widely, flask be in laboratory, use have a neck glassware, be used for holding liquid material, generally heat chemical experiment with it, cleaning process after experiment is generally: after flask is cooling, first wash with water, use again distilled water rinse, rinse process need has been assisted with the thing of similar hairbrush, existing hairbrush is all a stock, its leading section arranges bristle, due to the special construction of flask, easily cause its inwall to be brushed by bristle, and then affect cleaning effect, based on this, now need a kind of cleaning brush of scrubbing all bottles of flask wall.
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 flask cleaning brush is provided.
The technical solution of the utility model realizes in the following manner, this one chemical experiment flask cleaning brush, its structure comprises the adjustable pipe of upper end open and lower end closure, be slidably mounted on the adjustment cap on adjustable pipe, described adjustment cap is tubular and its centre is provided with the adjusting rod that stretches into adjustable pipe by governor motion, this governor motion comprises some being linked in sequence and up big and down small round table-like limiting tooth, the round table-like stopper slot that is opened on adjustable pipe inwall and is used in conjunction with limiting tooth, the leading section of above-mentioned adjusting rod is provided with hairbrush, be used in conjunction with hairbrush, on the anterior sidewall of adjustable pipe, offering hairbrush portals.By this technical scheme, student or teacher are in use by sliding up and down adjustment cap, just can under the effect of position-limit mechanism, regulate the position of adjusting rod, in folding process, bristle discharge from bristle portals automatically, form horizontal bristle, the extension elongation of bristle regulates by the actual bore of flask, and then user rotates this adjustment cap, can complete the cleaning of flask interior, on after finishing using, draw adjustment cap, bristle can be regained.
As preferably, the lateral wall of described adjustment cap caves inward and is provided with the gripping groove of closed hoop.The setting of this gripping groove is for the gripping of better person easy to use to whole cleaning brush, practical.
Further, on the inwall of described adjustable pipe lower end, be provided with taper projection, corresponding, adjusting rod bottom offers the cone tank of indent.Arranging on the one hand of this taper projection regulates restriction to the position of adjusting rod, and its conical outer surface facilitates the discharge of bristle on the other hand, makes its use convenient.
As preferably, between described this taper projection and adjustable pipe madial wall, be provided with parting bead, this parting bead portals hairbrush to be evenly separated into four separate wells.The separate wells of this quantity can better be swept into each corner of flask interior, and sweeping efficiency is higher.
The beneficial effect that the utility model compared with prior art produced is:
A kind of chemical experiment of the present utility model with flask cleaning brush have simple in structure, easy to use, the feature such as be skillfully constructed, by regulating the distance of adjusting rod in adjustable pipe, regulate the extension elongation of hairbrush, be applicable to the cleaning of the flask of different size, guarantee cleaning effect, do not stay dead angle, flexibility is good, design hommization more, practical, be easy to promote the use of.
