Abstract

The utility model discloses a handcart structure with a folding handle, comprising a grip section and a frame pivoted together. A stop board is pivoted at the lower end of the frame; a pair of wheels is pivoted at the lower end of the frame; a pair of stop collars is arranged at the periphery of the grip section. In use, the stop collars are pushed to the jointing part between the grip section and the frame, thus the handle is in a linear shape and is allowed to be pushed forward by force; when not used, the stop collars are pushed upward to reveal the jointing part between the grip section and the frame, thus the grip section is capable of being kinked downward. The utility model has the advantages of reduced volume and convenient carrying.

Description

The folding trolley structure of handle

Technical field

The utility model relates to hand barrow, relates in particular to a kind of handle section of handle can being amounted to downwards, to dwindle the grip structure of this hand barrow height.

Background technology

The hand barrow of conventional small as shown in Figure 1, be to be used to carry parcel, comprise the pair of right and left metal tube and make L shaped vehicle body 1, this vehicle body 1 front end is provided with the baffle plate 2 on plane, this baffle plate 2 just in time constitutes L shaped with this vehicle body 1, and handle 3 is extended in the upper end of this vehicle body 1, this handle 3 is for holding and can passing forward, the front lower left and right sides of this hand barrow is provided with a pair of wheel 4, this can land to wheel 4 during use, this vehicle body 1 just in time is obliquely installed when holding handle 3, and this vehicle body 1 the place ahead cooperates this baffle plate 2 to promote this hand barrow and can move goods for putting goods.

Just when not using hand barrow at ordinary times, hand barrow must be covered up and be placed on storage room or lean against on the wall, and preferably can be directly to erectting in order to avoid occupy too big space, yet because traditional its vehicle body 1 of hand barrow has certain height and can not amount to, can not reduced volume during folding and unfolding, especially when leaning at wall, if collided, this can roll out wheel 4, and vehicle body 1 is fallen down suddenly, thereby visible traditional hand barrow not only places difficult, also under cover dangerous.

Therefore, the utility model designer relies on the many years of experience of its production and marketing like product, constantly concentrates on studies and improved test, succeeds in developing the utility model that has practical value now finally.

The utility model content

Main purpose of the present utility model, be to provide a kind of handle folding trolley structure, this handle comprises handle section and the vehicle frame that is articulated, this handle section is by the pair of right and left body and connect this pipe link to body and form, make this handle section roughly be inverted U-shaped, this vehicle frame lower end articulates baffle plate, this baffle plate can upwards change with by being attached to this vehicle frame front side, and there is a pair of wheel to be articulated in this vehicle frame lower end, this can be inwardly to wheel then folds at this central frame beam, the stop collar bundle of two tubuloses is in the body periphery of this handle section, this stop collar can be shifted the articulated section of this handle section and this vehicle frame onto during use, thereby but make the linearly application of force promotion of this handle, this stop collar can be pushed away the articulated section of this handle section and this vehicle frame when not using, this handle section can be bent downwards, reach the purpose that reduced volume is beneficial to carrying and collection.

The specific embodiment

See also shown in Fig. 2 and 3, the utility model relates to the folding trolley structure of handle, and this hand barrow comprises:

Handle 10, this handle 10 comprises handle section 12 and the vehicle frame 13 that is articulated, handle section 12 is by the parallel a pair of body in the left and right sides, cooperate the upper end laterally to connect this pipe link 11 and constitute, make handle section 12 roughly become inverted U-shaped, the section ovalize of body body, handle section 12 bodys of side bottoms socket stick harness 121 wherein, stick harness 121 lower ends outwards expansion so that the lower end external diameter greater than the upper end, a side is provided with groove and laterally is provided with pivot hole 122, pivot hole 122 is for latches 123 cross-under.

Vehicle frame 13 is made of a pair of body, the section ovalize of body, its open top can be inserted in articulated part 131, articulated part 131 tops articulate the rotatable insertion section 132 of sheet, insertion section 132 can pack into the groove of stick harness 121, and by latch 123 cross-under stick harness 121 and articulated part 131 is articulated so that bent.

And the stick harness 121 of opposite side handle section 12 is and swings to, and being enclosed within the body open top of vehicle frame 13 homonymies, and the articulated part 131 of opposite side also is and swings to be enclosed within the body bottom of handle section 12 homonymies.

Two cross bars 14, these cross bar about 14 ends can wrap on the left and right sides body of establishing and be fixed on vehicle frame 13.

The stop collar 15 of two tubuloses, the aperture of this stop collar 15 cooperates the tubular form of handle section 12, can encircle the body periphery of bundle in handle section 12, and can be toward moving down so that stick harness 121 and articulated part 131 are coated on its inside.

A pair of wheel 20, this wheel 20 laterally is articulated on the wheel seat 21, a side of wheel seat 21 is provided with: circular directly to sleeve pipe 22, these sleeve pipe 22 top internal diameters outwards expansion so that its external diameter becomes big and internal perisporium is equipped with a plurality of latches 23; The ring gear 24 of inner hollow, these ring gear 24 internal diameters cooperate the tubular form of vehicle frame 13 and can be enclosed within vehicle frame 13 peripheries, the lower end of ring gear 24 is outwards expanded so that its external diameter becomes big and rounded, and make its inner loop establish a plurality of double wedges 25, double wedge 25 meshes with the latch 23 of sleeve pipe 22, makes wheel seat 21 can rotate and be with wheel 20 to collapse in the middle of the vehicle frame 13 inwardly.

The baffle plate 30 of sheet, these baffle plate 30 rear left and right sides respectively are provided with cover ear 31, be inserted in the buy car in installments lower end of frame 13 of this cover ear 31, and attaching nut 33 is sealed again to pass through bolt 32 horizontal cross-under, make baffle plate 30 be articulated in the lower end of vehicle frame 13, can be vertical mutually with vehicle frame 13, and can upwards start with by being attached to the front side of vehicle frame 13.

By above-mentioned structure, but baffle plate 30 can down be pulled out vertical each other so that bearing goods with vehicle frame 13 during use, this can outwards produce wheel 20 and be positioned at vehicle frame 13 belows, in ground surface, make handle section 12 and vehicle frame 13 be same straight line again, stop collar 15 down pushes away again, can wrap to connect stick harness 121 and articulated part 131, make handle section 12 and vehicle frame 13 fixedly be a straight line, pipe link 11 can provide holds passing.

When folding, baffle plate 30 can up be pulled, to abut in the front side of vehicle frame 13, this to wheel 20 more inwardly then be positioned in the middle of the vehicle frame 13, stop collar 15 can up push away, can expose stick harness 121 and articulated part 131 this moment, handle section 12 can down bend, abut in the rear side of vehicle frame 13, the volume that therefore can dwindle whole hand barrow is so that collection, and hand can be held cross bar 14 and mentions and move when mobile.

In sum, the utility model can reach its desired purpose and effect.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model.In the above-described embodiments, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
