Abstract
The utility model discloses a brake structure of a trolley. A frame (12) of a wheel is provided with a stop hole (15). A brake capable of rotating around a rotating rod (6) arranged on a supporting leg (2) is provided with a brake plate (8a). The other end of the brake is connected with a steel cable (11). A spring (20) arranged between the supporting leg and the brake is used for ensuring that under the normal condition, the brake plate (8a) is inserted into the stop hole (15) to play the braking function, so that the trolley is in a locked state; and when the steel cable (11) is pulled, the brake rotates and the brake plate (8a) is separated from the stop hole (15), so that the trolley can continuously move.
Description
Technical field
The utility model relates to a kind of drg structure about hand barrow.
Background technology
The drg of installing on the hand barrow that is used to transport goods is configured with multiple, for example, publication number 2002-81474 number spy opens and discloses a kind of hand barrow drg structure in the bulletin, be on the vehicle wheel frame of hand barrow, to bore a hole, insert a mobile rod that stops and making it become lock-out state, when stopping then to become released state when rod breaks away from the hole.
Disclosed drg structure in the above-mentioned bulletin, though can in the hole, insert and stop rod and make it become lock-out state, but when the bigger article of hand barrow loaded weight, and when before the slope, stopping, the described rod that stops will to bear sizable heavy burden, and the rod that stops of only fixing an end holds and can't stand big like this heavy burden, and it is crooked therefore can to cause stopping rod, misfunctioning of brake.
Summary of the invention
The utility model is at above problem, and a kind of drg structure of hand barrow is provided, even this drg structure also can keep firm when hand barrow has than heavy load.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of drg structure of hand barrow is equipped with wheel on the feet below the support board, the vehicle frame of wheel is provided with stop aperture; Feet is provided with the single-revolution rod, and revolution is equipped with drg on the rod, and an end of described drg be for can inserting the brake plate in the described stop aperture, and the other end of drg is connected with and is used for cable wire that described brake plate is deviate from from stop aperture; One spring is set between feet and drg, is used for the control brake sheet to insert it in the stop aperture.
Preferably, described brake plate is an oblong, and and vehicle frame on slightly gapped between the oblong stop aperture that is provided with.
In addition, preferably, when lock-out state, by being the moment of transference that the oblong brake plate of fulcrum bears wheel to turn round rod.
Hand barrow drg structure of the present utility model changes the locking and unlocking state of hand barrow by the stop aperture on brake plate insertion or the separating wheel, this brake plate is a fulcrum with the revolution rod that installs on wheel, bear whole moment of transference of wheel, though only fix an end, but because its distance to fulcrum is very short, even the load capacity of hand barrow is very big, also be that length with galianconism is arm of force factored moment, the arm of force is short, and suffered moment is just little, therefore, described brake plate can bear whole bearing capacities, that is to say, even load weight on the hand barrow, when the dip plane stopped, drg structure of the present utility model also can bear fully.
Description of drawings
Fig. 1 is the wheel Facad structure of hand barrow drg structure of the present utility model.
Fig. 2 is the right flank constructional drawing of Fig. 1 when lock-out state.
Fig. 3 is the right flank constructional drawing of Fig. 1 when released state.
The specific embodiment
About embodiment of the present utility model, can be with reference to the wheel Facad structure figure of hand barrow shown in Figure 1, and the right flank constructional drawing 2 when lock-out state, the right flank constructional drawing 3 when released state describes.
As shown in the figure, four jiaos below hand barrow support board 1 respectively are provided with a pair of feet 2, and wheel 10 is installed on a pair of feet 2 by axis of revolution 3, can wraparound rotating shaft 3 rotate.In addition, around the vehicle frame 12 of wheel 10, rubber bodies 13 is installed also.
On the vehicle frame 12 of above-mentioned wheel 10, be provided with a plurality of rectangular stop apertures 15 towards axis of revolution 3 (wheel center).In addition,, then can use a new metal sheet on vehicle frame 12, on this metal sheet, wear stop aperture 15, and this metal sheet is filled on the vehicle frame 12 if other perforation has been arranged.
In addition, there is the support 5 of pair of L-shaped to be fixed on the above-mentioned feet 2, single-revolution rod 6 is installed in the space of described a pair of support 5 with direction perpendicular to support board 1.On this revolution rod 6, a L shaped drg 8 is installed, can rotates by wraparound transfer rod 6.The end of drg 8 is connected with cable wire 11, and the other end is for there being the brake plate 8a of certain thickness tabular (cuboid), and brake plate 8a can insert in the stop aperture 15 on the vehicle frame 12 perpendicular to vehicle frame 12, and and stop aperture 15 between slightly gapped.
Also have, spring perch 19 is installed on feet 2, a spring 20 is housed between spring perch 19 and the drg 8.Spring 20 can stretch, and generally, spring 20 keeps described brake plate 8a to insert the state of stop aperture 15.In addition, adopt independently spring 20, be in different positions about brake plate 8a for left and right wheels, for stop aperture 15, can be independently corresponding.
Effect to above-mentioned drg structure describes below.
Scheme drawing when Fig. 2 is drg locking state that is to say that generally, spring 20 is stretched to the direction of spring perch 19 drg 8, and the brake plate 8a of drg 8 other ends is in the state that inserts stop aperture 15 because of the effect of this tensile force.Therefore, even wheel 10 is wanted to move, but, it is in the lock state because brake plate 8a stop to move.
At this moment, the length of the relative stop aperture 15 of brake plate 8a has certain respective amplitude, and this amplitude will be born the turning effort of wheel.That is to say that moment of transference is distributed load-bearing, the fulcrum of brake plate 8a is the revolution rod of installing on the feet 26, though only fix an end, because very short to the distance of fulcrum, moment of transference reduces, and brake plate 8a can bear whole strength.That is to say that even load weight on the hand barrow, when stopping in the dip plane, this drg structure also can bear.
Next, pulling cable wire 11, drg 8 overcomes the tensile force of above-mentioned spring 20, is fulcrum to turn round rod 6, rotates in a clockwise direction in Fig. 2, and brake plate 8a breaks away from (Fig. 3) from stop aperture 15, and drg is removed and is become released state, and hand barrow can be advanced.
The installation that the drg of the above hand barrow structure is can be on feet 2 easy also can simply be installed on the hand barrow of having sold.In addition, the utility model is when lock-out state, for the moment of wheel, the pivot distance of revolution rod 6 is very short, and bears moment by brake plate 8a, for because of being loaded with the hand barrow of moment of transference greatly that weight produces, can not damage the drg structure, can bear fully.
In addition, above-mentioned drg is configured in when generally drg plays a role and is in the lock state, still, the structure opposite with it, promptly the state that generally can advance also is suitable for.In addition, drg structure of the present utility model can be installed in the outside or the inboard of feet.
In addition, the section form of brake plate 8a is not limited to top said oblong, and elliptoid and shape that section factor is bigger also can be used, and the shape of above-mentioned stop aperture is decided with the section form that adapts to above-mentioned brake plate.
