Abstract

The utility model provides a movable double-brake trundle comprising a bottom plate, a first rivet, a steel ball, a first wave plate, a second wave plate, a support, a wheel, a bolt, an anti-loosening nut, an anti-winding cover, a gear gasket, a pedal, a reset button, a metal double-brake piece and a second rivet. The pedal is arranged at the upper end of the support through the second rivet. A groove opening for the reset button to pass through penetrates through the middle of the pedal. The reset button is arranged under the pedal and corresponds to the groove opening. The reset button is in pivot connection with one end of the metal double-brake piece through a first plug pin. The other end of the metal double-brake piece is installed in the interior of the upper end of the support through a second plug pin crossing the support. A plurality of insertion teeth are arranged at the upper end of the metal double-brake piece along the extending direction of the gear gasket. The middle of the upper end of the metal double-brake piece extends along the bottom direction of a top plate to form a pressing plate contacting with the metal double-brake piece. The movable double-brake trundle is good in wheel-braking effect, high in safety and reliability, and capable of meeting the wheel-braking function and achieving orientation of the support.

The specific embodiment

Below in conjunction with specific embodiment the utility model is described further.

Shown in accompanying drawing 1 to accompanying drawing 9; The described movable dual brake castor of present embodiment; It include base plate 1, first rivet 2, steel ball 3, the first ripple dish 4, the second ripple dish 5, support 6, wheel 7, bolt 8, black nut 9, anti-twine cover 10, toothed washer 11 (being specially flat tooth pad), stretcher 13 (being specially Plastic Parts), reset button 14 (being specially Plastic Parts), metal dual brake sheet 15, second rivet 16; Wherein, In the upper end of support 6, and this base plate 1 and the first ripple dish, 4 correspondences are located at the top, upper end of support 6 by from top to bottom order first rivet, 2 riveteds through vertically-arranged for the said base plate of present embodiment 1, the first ripple dish 4, the second ripple dish 5, toothed washer 11; The second ripple dish 5 is inner with the upper end that toothed washer 11 correspondences are located at support 6; Simultaneously, the said first ripple dish 4 and the second ripple dish 5 contact with the edge of opening of the top board 12 of support 6 through steel ball 3 separately, realize its rotation of sliding; Said wheel 7 is installed in the wheel installation position of this support 6 through the bolt 8 that is horizontally through support 6 lower end foots; And; This bolt 8 is through black nut 9 lockings; Simultaneously, the both sides of wheel 7 are equipped with anti-twining respectively and are covered 10, can prevent effectively that castor is involved in foreign material in the deep groove ball bearing on wheel 7 both sides and on the bolt 8 in operation process; Said stretcher 13 is through the upper end of second rivet, 16 riveteds at support 6; Simultaneously, the middle part of this stretcher 13 is penetrated with the notch 17 that a confession reset button 14 passes, and reset button 14 is located at the below of this stretcher 13; And it is corresponding with above-mentioned notch 17; This reset button 14 articulates through the end of first latch 18 with metal dual brake sheet 15, simultaneously, on this end of metal dual brake sheet 15 towards wheel 7 be formed with one when stopping wheel the stop wheel convexity 19 inconsistent with wheel 7; The other end of said metal dual brake sheet 15 is inner through the upper end that second latch 20 that crosses support 6 is installed in support 6; And; This end of metal dual brake sheet 15 is extended with three gear shapings 21 that when stopping wheel, are used for stuck toothed washer 11 toward the direction of toothed washer 11; Simultaneously, the bottom direction toward top board 12 is extended with the pressing plate inconsistent with it 22 in the middle part of this end of metal dual brake sheet 15.During use, after stepping on stretcher 13, metal dual brake sheet 15 touches wheel 7, and wheel 7 can not be rotated, and simultaneously, the gear shaping 21 of this metal dual brake sheet 15 blocks toothed washer 11, and support 6 can not be rotated, and plays stop wheel and directed effect simultaneously; And when stepping on reset button 14, metal dual brake sheet 15 leaves wheel 7 and toothed washer 11, makes support 6 and wheel 7 recover to rotate.In a word, after adopting above scheme, easy to operate simple, the wheel better effects if of stopping, the safe reliability of the utility model are higher, when satisfying the wheel function of stopping, can realize the orientation of support 6 again, are worthy to be popularized.

The examples of implementation of the above are the preferred embodiment of the utility model only, are not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
