Detailed description of the invention

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

A kind of round-bottomed flask cleaning brush of the utility model, structure as Figure 1-3, comprise brush holder support 1, brush holder support 1 offers groove A8, groove B9 respectively along the two ends in bar footpath, the groove of groove A8 is high, the groove of groove B9 is high all by through for the end, one end of brush holder support 1, end, one end hollow of brush holder support 1, the end, one end of brush holder support 1 is embedded with the brush 2 of strip, and the width of brush 2 equals the groove width of groove B9 and is less than groove A8.

The hollow ends of brush holder support 1 offers through hole C10, through hole D11 respectively along the two ends in bar footpath, and the bar footpath of through hole C10, through hole D11 place brush holder support 1 is vertical with the bar footpath of groove A8, groove B9 place brush holder support 1; The upper surface of brush 2 offers through hole E12 (see Fig. 4), the lower surface of brush 2 is evenly equipped with bristle 4, brush 2 is connected with brush holder support 1 through through hole C10, through hole E12, through hole D11 by connecting rod 3 successively, the bar length direction of connecting rod 3 is vertical with the length direction of brush 2, and the two ends of brush 2 are corresponding with the position of groove A8, groove B9 respectively.

Connecting rod 3 is interference fit with the fit system of through hole C10, through hole D11; Connecting rod 3 is matched in clearance with the fit system of through hole E12.

Through hole E12 is positioned at the centre position of brush 2 upper surface.

The tall and big groove in groove B9 of groove of groove A8 is high, and the groove height of groove A8 is the half of brush 2 length.The groove face of groove A8 and the angle of horizontal plane are 45 ° ~ 85 °, and the groove face of groove B9 and the angle of horizontal plane are 95 ° ~ 175 ° (the original bench mark lines that groove A8, groove B9 and horizontal plane angulation are angle with unidirectional horizontal line).

Brush holder support 1 has through hole A6 along direction, bar footpath symmetry, through hole B7, through hole A6 offers along the shaft inside of brush holder support 1 and corresponding with groove A8 through, through hole B7 offers along the shaft inside of brush holder support 1 and corresponding with groove B9 through, support bar A is equipped with in the inside of through hole A6, support bar B is equipped with in the inside of through hole B7, end, support bar A one end, the end, one end of support bar B all contacts with the upper surface of brush 2, the upper surface of brush 2 offers the groove C13 coordinated with the end, one end of support bar A respectively, the groove D14 of end, one end cooperation of support bar B, groove C13, groove D14 lays respectively at the both sides of through hole E12, groove C13 coordinates with support bar A's, groove D14 is threaded engagement with coordinating of support bar B, the other end of support bar A stretches out from through hole A6 another port, and the other end of support bar B stretches out from the another port of through hole B7, and support bar A, in through hole A and by threaded engagement in groove C13, is fixed on brush 2 with this by support bar A movable set, support bar B, in through hole B and by threaded engagement in groove D14, is fixed on brush 2 by support bar B movable set successively.

The other end of brush holder support 1 is provided with hand 5, and hand is hollow ring 5.

The using method of a kind of round-bottomed flask cleaning brush of the utility model is, before this device is stretched into round-bottomed flask, first manual by part brush 2 with in groove A8 (see Fig. 5), (now support bar A is taken out from through hole A6, support bar B takes out from through hole B7) due to the groove face of groove A8 be arcwall face, therefore brush 2 is embedded in groove A8 in skewed, for opening of follow-up brush 2 provides conveniently, now this device is stretched into round-bottomed flask inside, when brush 2 touches bottom round-bottomed flask, downward power is applied to brush holder support 1, be embedded in brush 2 in groove A8 to be separated with groove A8, brush 2 becomes in the flask of horizontal positioned from vertical placement originally, now just can scrub flask, when needing the sidewall cleaning flask, support bar A is stretched into from through hole A6 and screws in groove C13, by manually exerting a force to support bar A, brush 2 tilts to the direction of groove B9, now rotary brush rod 1 just can clean the sidewall of round-bottomed flask, after cleaning, again moving brush holder support 1 is that brush 2 contacts with the bottom of round-bottomed flask, brush holder support 1 is exerted a force, that brush 2 level is disposed across in flask, now, support bar A is screwed out from groove C13, take out support bar A, support bar B is stretched into from through hole B and screws in groove D14, through hole manually exerts a force to support bar B, brush 2 is tilted towards the direction of groove A8, groove width due to groove A8 is greater than the width of brush 2, therefore brush 2 can be taken advantage of a situation and is embedded in groove A8, brush 2 is made to get back to initial position (position shown in Fig. 5 is initial position), this device is taken out in flask.

The feature of a kind of round-bottomed flask cleaning brush of the utility model is, this apparatus structure is simple, is easy to realize, meets user demand, effectively raise the cleaning efficiency of round-bottomed flask while cost of manufacture is low.
