Description
Technical Field
The utility model relates to a laboratory apparatus field, concretely relates to receive and release rod-type round flask cleaning brush.
Background
Round-bottomed flasks, which are glass containers common in biochemical laboratories, are often filled with solution formulations for experiments, resulting in a lot of residue remaining on the inner wall. The device that is used for abluent at present belongs to the bar very much, and is comparatively easy to the washing of the narrower neck of flask, nevertheless is difficult to the washing of lower part body broad to difficult realization all-round washing. In order to reduce the waste of resources and the burden of cleaning, an apparatus capable of cleaning a round-bottomed flask with higher efficiency and better adaptability is required.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a receive and open a pole formula round flask cleaning brush to solve the inconvenient abluent problem of inner wall of round flask among the prior art, realize improving the cleaning efficiency to round flask and the purpose of effect.
The utility model discloses a following technical scheme realizes:
a telescopic rod type round-bottom flask cleaning brush comprises a supporting rod and a guide sleeve movably sleeved outside the supporting rod, wherein the bottom end of the guide sleeve is hinged with N straight rods which are uniformly distributed in a ring shape, and N is more than or equal to 2; one end of the straight rod, which is far away from the guide sleeve, is hinged with an arc rod, the concave surface of the arc rod faces the direction of the axis of the supporting rod, and one end of the arc rod, which is far away from the straight rod, is hinged with the bottom end of the supporting rod; the middle lower part of the guide sleeve, the straight rod and the arc rod are all provided with bristles.
The inconvenient abluent problem of inner wall to among the prior art round flask, the utility model provides a receive and open pole formula round flask cleaning brush, the uide bushing can be along endwise slip outside the supporting rod, the straight-bar of the articulated N root ring shape equipartition in bottom of uide bushing, the effect of straight-bar is convenient for stretch into the neck position of round flask top, the circular arc pole articulates the lower extreme at the straight-bar, and the circular arc pole is kept away from the one end of straight-bar and the bottom of supporting rod is articulated, so when the relative uide bushing downstream of supporting rod, the bottom downstream of supporting rod pulling circular arc pole, pull the circular arc pole to being close to the supporting rod, and the circular arc pole pulls the straight-bar again, make the straight-bar also be close to the bracing piece, thereby make straight-bar and circular arc pole all draw in to the supporting rod direction, thereby be convenient for insert to the round. When the circular arc section is inserted into the round-bottom flask, the supporting rod moves upwards relative to the guide sleeve, if the supporting rod is kept still and the guide sleeve is pressed downwards, the straight rod and the circular arc rod are both opened along the radial direction, and the brush hair on the straight rod and the circular arc rod is fully attached to the inner wall of the round-bottom flask, so that the inside of the round-bottom flask can be cleaned. Wherein the middle-lower part of the guide sleeve is also provided with bristles, so that the neck part of the round-bottom flask can be synchronously cleaned. The length of brush hair in this application set up according to concrete needs can, the brush hair on straight-bar, the circular arc pole all can set up to the shape that the terminal surface is the arc and distributes to can laminate with round flask inner wall more, however, the chooseing of brush hair length should be long should not be short.
The bottom of the supporting rod is fixedly connected with a connecting block, and all the arc rods are hinged on the connecting block. Set up N root straight-bar and circular arc pole in this application, be in order to show the reinforcing to the cleaning efficiency of round flask inner wall, can set up the brush hair on different straight-bar and the circular arc pole into different soft or hard degree even to this simulates the abluent process of manpower, improves cleaning efficiency through the constantly changing of rotation in-process frictional force.
