Description
Technical field
The utility model is related to a kind of assist transportation vehicles.
Background technology
In daily life in industry-by-industry, and usually, when being frequently encountered needs carrying compared with heavy articles.
For the ease of carrying compared with heavy articles, it will usually use a carrier, article is moved on carrier, carrier is then passed through
Handle direct pull.Although part strength can be saved than directly carrying article in this way, but larger strength is needed to pull
Carrier.When article is more heavier, still need article are smoothly moved to other positions using larger strength.
Invention content
It is easy to operate the technical problem to be solved by the present invention is to provide a kind of assist transportation vehicle, strength is saved, is reduced
Carry difficulty.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of assist transportation vehicle, including loading plate, loading plate bottom are set there are two front-wheel and two trailing wheels, described two front-wheels
It is fixedly connected by front axle, the position that the rear portion of support plate corresponds to trailing wheel is equipped with hind axle, and fixing sleeve is equipped with rear tooth on hind axle
Wheel, fixing sleeve is equipped with front gear on front axle, and front gear is connect by chain with backgear, on hind axle activity attaching have hand
Handle is equipped with ratchet mechanism between handle and hind axle.
The ratchet mechanism includes ratchet and kelly, and handle, at its lower end is equipped with ratchet card slot, after ratchet is fixedly set in
On wheel shaft and in the ratchet card slot, kelly is located in handle and faces ratchet, and the upper end of kelly, which upwardly extends, is pierced by hand
Handle upper end, kelly lower end are set as inclined surface.
It is set with spring on the kelly.
The handle includes holding rod and two vertical bars, and holding rod is under the upper end of two vertical bars, two vertical bars
End is attached separately on front axle.
The upper end of the kelly is equipped with rotation gear handle.
The cross-sectional area of the front gear is more than back-geared cross-sectional area.
The position that handle is corresponded on the loading plate offers operation card slot.
The utility model is easy to operate, it is only necessary to which pushing handle can push front wheels and rear wheels to rotate, before realizing car
It moves or retreats, save strength.
Description of the drawings
Attached drawing 1 is the utility model dimensional structure diagram；
Attached drawing 2 is the schematic diagram of the utility model trailing wheel shaft portion；
Attached drawing 3 is the decomposition diagram of the utility model ratchet mechanism and mobile phone；
Attached drawing 4 is enlarged diagram at the A in attached drawing 3.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in attached drawing 1-4, the utility model discloses a kind of assist transportation vehicle, including loading plate 1, and 1 bottom of loading plate is set
There are two front-wheels 10 and two trailing wheels 5, described two front-wheels 10 to be fixedly connected by front axle 11, and the rear portion of support plate plate 1 corresponds to
The position of trailing wheel 5 is equipped with hind axle 6, and fixing sleeve is equipped with front gear 12 on front axle 11, and fixing sleeve is equipped with backgear on hind axle 6
8, front gear 12 is connect by chain 7 with backgear 8, on hind axle 6 activity attaching have handle 3, between handle 3 and hind axle 6
Equipped with ratchet mechanism.Loading plate 1 is equipped with operation card slot 4, is convenient for the rotation of handle, handle 3 can be into around hind axle 90
Suitable damping can be arranged, it is ensured that handle needs to overcome certain resistance ability in the rotation of degree between handle 3 and hind axle 6
Rotation, makes it naturally not rotated because of its own gravity.Front axle and hind axle can be installed by supporting plate and loading plate respectively.
Rear wheel is assemblied on loading plate, can be turned to, front-wheel is then in stays.
The ratchet mechanism includes ratchet 9 and kelly 13, and 3 lower end of handle is equipped with ratchet card slot 15,9 fixing sleeve of ratchet
On hind axle 6 and in the ratchet card slot 15, kelly 13 is located in handle 3 and faces ratchet 9, the upper end of kelly 13
It upwardly extends and is pierced by 3 upper end of handle, 13 lower end of kelly is set as inclined surface 16.By adjusting kelly inclined surface relative to ratchet
The limitation that ratchet is counterclockwise and rotates clockwise is realized, it is ensured that ratchet can only be towards counterclockwise or rotationally clockwise in direction.
It is set with spring 14 on the kelly 13, realizes automatically reseting for kelly.
The handle includes holding rod and two vertical bars, and holding rod is under the upper end of two vertical bars, two vertical bars
End is attached separately on front axle.The upper end of kelly 13 is equipped with rotation gear 2, adjusting easy to operation.
The cross-sectional area of the front gear is less than back-geared cross-sectional area.It is driven by smaller backgear larger
Front gear rotation, more vigor.
The utility model utilizes lever principle, adjusts the direction of the inclined surface of kelly.As shown in Fig. 4, ratchet is limited
Only towards rotating counterclockwise.If the inclined surface by kelly is reversed, ratchet is limited only towards rotationally clockwise, from
And realize the forward or backward of car.Then handle is pushed, handle opposing rear wheels shaft rotation is dynamic, and then drives ratchet by kelly
Rotation, the rotation of ratchet drive the rotation of hind axle, and the rotation of hind axle drives back-geared rotation, to pass through chain-driving
The movement of car is realized in the rotation of front gear, saves strength.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
