Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings.

Embodiment one,

With reference to figure 1-3, the utility model proposes a kind of pedal assembly, which includes tie-beam 1 and pedal 2, It is connected by shaft 3 between pedal 2 and tie-beam 1, the pedal is internally provided with a removable pin, on the end face of 1 one end of tie-beam Equipped with the arc chute 4 coordinated with removable pin, the both ends of arc chute 4 are respectively provided with a limiting slot 41, through living described in outer force effect The end of dynamic pin can be inserted into another limiting slot by a limiting slot of arc chute.The pedal of this wheelbarrow is in expansion or folded state When, removable pin is inserted into limiting slot, to prevent the arbitrary rotation of pedal, when pedal needs to become folded state from unfolded state Or when from folding becoming unfolded state, removable pin can be extracted out from the limiting slot of place and arcuately sliding slot is rotatably inserted into another One limiting slot, to prevent pedal from arbitrarily rotating.

The removable pin of the present embodiment includes the attacker's key 5 that can be passed in and out inside pedal, fixed block 6, pin rod 7.Wherein, fixed block 6 are fixedly arranged on inside pedal 2, and the fixed block 6 is equipped with through-hole 61, and one end of the pin rod 7 passes through fixed block 6 and attacker's key 5 Connection, the pin rod 7 are equipped with the stopper section for preventing 7 end of pin rod to be detached from annular groove.As shown in Figure 1, the button of the present embodiment Hand key bottom offers a groove, in order to pull out attacker's key out of pedal.Stopper section is for preventing the end of pin rod to be detached from Sliding slot ensures the normal use that pedal folds and is unfolded.

Specifically, the pin rod 7 of the present embodiment is cylindric comprising what is be sequentially arranged can be moved forward and backward along fixed block through-hole Backstop section 72 on the outside of fixed block of initial segment 71 and backstop, the wherein diameter of initial segment is less than the diameter of backstop section, The top surface of middle backstop section can backstop on the outside of fixed block, be detached from from arc chute to prevent shotpin bar end, backstop section 72 is equipped with One circle annular table 721.Removable pin further includes spring 8, and spring 8 is sleeved on pin rod 7, and both ends of the spring is limited to the fixed block 6 Between annular table 721, spring can prevent pin rod from arbitrarily shaking；And when pin rod is inserted in any limiting slot, it can guarantee Pin rod withstands on the annular table on pin rod so that pin rod is limited in limiting slot.

The tie-beam includes mounting plate 11 and the tie-beam ontology 12 being arranged below mounting plate, and mounting plate is equipped with Mounting hole, convenient for pedal to be mounted on wheelbarrow car body, the arc chute is arranged on tie-beam ontology.

The tie-beam is equipped with the through-hole coordinated with shaft 3, and the arc chute is close to tie-beam ontology one end end face Through-hole setting, and the inner arc of the arc chute of the present embodiment is under, and outer arc is convenient for the sliding of pin rod upper.

The mounting plate is equipped with a pillar, and the pedal is equipped with the groove coordinated with pillar, beautiful.

When needing to ride, pedal pulls out attacker's key from unfolded state is folded into, and pin rod end is left on arc chute The limiting slot of side, rotary pedal so that arcuately sliding slot slides the limiting slot for reaching lower section for the end of pin rod, and attacker's key is promoted Pedal, pin rod end enter the limiting slot of the lower section of arc chute, and pedal is unfolded and fixes to prevent from arbitrarily shaking at this time.It needs It is identical as aforesaid operations mode when foldable pedal so that pin rod end is entered the limiting slot of top by the limiting slot of lower section, herein It repeats no more.

Embodiment two,

In addition, the utility model also proposes a kind of wheelbarrow, the pedal assembly being equipped on the wheelbarrow in embodiment one, Since the technical solution of pedal assembly is similar to embodiment one, details are not described herein.

The wheelbarrow of the utility model includes wheel hub 12, shell 10.Two groups of tires of left and right, two groups of wheels are installed on wheel hub The gas tube of two groups of inside tires gas connections can be made by being equipped between tire.

There is a handle 9 on the top of the shell of the present embodiment, material is leather, wear-resisting, and increases the comfort level of lifting.

First, the utility model is arranged gas tube between two groups of tires, protects by the way that the two groups of tires in left and right are arranged on wheel hub Gas between two groups of tires is demonstrate,proved to be interconnected, when people will turn round to the left, just the center of gravity of entire body to Left-Tilt, The pressure that at this time left side tire is subject to is more than the pressure that the right tire is subject to, since two tires in left and right are connections, so It cincture tyre cavity surface current can be moved to the right after gas is squeezed inside the tire of the left side, then the diameter L2 of wheel portion becomes on the right of wheelbarrow Greatly, the diameter L1 of left side wheel portion becomes smaller, and the angular speed W of two partial turns in left and right is the same, according to speed S=L* W then uses S2>S1, so entire car is just turned to the left.The principle to bend to right is also same.

It is provided with left and right two tire slots on the wheel hub of the present embodiment, one is separately installed on the two tire slots in left and right A tire 11, i.e. left tire and right wheel tire, the number of every group of tire is 1 in this implementation, in the feelings for ensureing that wheel facilitates turning Under condition, it is possible to reduce the width of vehicle.

The wheelbarrow of the utility model is not only convenient for turning, moreover, when one foot of user he on a pedal when, prevent Pedal arbitrarily folds, and ensures safety.

Above example is only to illustrate the technical solution of the utility model, rather than is limited；Although with reference to before Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right Technical solution recorded in previous embodiment is modified or equivalent replacement of some of the technical features；And these Modifications or substitutions, the utility model technical solution claimed that it does not separate the essence of the corresponding technical solution spirit and Range.
