Description

A kind of Novel single-wheel barrow

Technical field

This utility model is related to a kind of means of transport, and in particular to a kind of Novel single-wheel barrow.

Background technology

Using very extensively in real life, which flexibly, unloads thing fast side with compact, convenient transportation to single-wheel barrow Just, it is deep to be liked by user；But in actual use, tended to due to the muscle power and operation skills problem of user Cause car body to turn on one's side, and rollover is occurred mainly in when unloading thing；Single-wheel barrow unloads the center of gravity phase that thing mainly uses object to be carried Skew to axis wheel, and wagon box is overturn around hinged end, and then realize quickly unloading thing；People are using single-wheel barrow When, the center of gravity of articles carried is partial to wagon box rear sometimes, so, the muscle power output of user is increased when thing is unloaded, and The occurrence of being also easy to car body occur turn on one's side, brings unnecessary life to damage or item spoilage.

Utility model content

The purpose of this utility model is to provide a kind of Novel single-wheel barrow, it is intended to make the single-wheel barrow using more pacifying It is complete convenient, safety and the convenience for increasing which uses is improved by structure, it is to avoid the occurrence of rollover, reduce user and unload Muscle power output during thing.

The technical solution adopted in the utility model：

A kind of Novel single-wheel barrow, including handle, supporting leg, steelframe, wagon box and wheel, also including lengthen rotary shaft, the One linking arm and the second linking arm, the wheel are arranged in the middle part of lengthening rotary shaft, and the steelframe is connected by the first linking arm Rotating shaft terminal is being lengthened, one end of second linking arm is hinged on the front end of wagon box bottom, and its other end is hinged on lengthening In rotary shaft, second linking arm of distance of shaft centers for lengthening rotary shaft is more than lengthening rotary shaft with the distance in wagon box hinged end axle center Distance of shaft centers steelframe upper surface distance, the front end of the steelframe arranges limited location lever；

Further, the rear end of the wagon box bottom is provided with slide block, is provided with and is adapted with the slide block on the steelframe Slideway.

The beneficial effect of this utility model embodiment is：

It is this utility model simple structure, easy to use；Using action of gravity, make wagon box on steelframe toward polyslip, and then The center of gravity fast excursion after goods is filled in wagon box is realized, thing is unloaded in the quick upset beneficial to wagon box, center of gravity under gravity Skew saves the muscle power output of user, and which is using more safe ready.

Wherein：1- handles；2- supporting legs；3- steelframes；4- wagon boxes；5- wheels；6- lengthens rotary shaft；The first linking arms of 7-；8- Second linking arm；The spacing levers of 9-；10- slide blocks；11- slideways.

Specific embodiment

This utility model preferred embodiment is illustrated below in conjunction with accompanying drawing：

As shown in Figures 1 to 3, a kind of Novel single-wheel barrow, including handle 1, supporting leg 2, steelframe 3, wagon box 4 and wheel 5, also Including rotary shaft 6, the first linking arm 7 and the second linking arm 8 is lengthened, the wheel 5 is arranged in the middle part of lengthening rotary shaft 6, described Steelframe 3 is connected to 6 two ends of lengthening rotary shaft by the first linking arm 7, and one end of second linking arm 8 is hinged on 4 bottom of wagon box The front end in portion, its other end are hinged in lengthening rotary shaft 6, second linking arm of distance of shaft centers 8 and wagon box for lengthening rotary shaft 6 Distance of the distance of 4 hinged ends axle center more than 3 upper surface of distance of shaft centers steelframe for lengthening rotary shaft 6, the front end of the steelframe 3 are arranged Limited location lever 9；The rear end of 4 bottom of the wagon box is provided with slide block 10, is provided with and is adapted with the slide block on the steelframe 3 Slideway 11.

In this utility model：When the single-wheel barrow is normally placed, steelframe 3 is inclined obliquely, and wagon box 4 is from heavy sensation of the body The oblique lower slider of power, and then drive the second linking arm 8 to rotate around rotary shaft 6 is lengthened, it is located at the second linking arm 8 and lengthens rotation The rear of axle 6, after filling article, 4 center of gravity of wagon box is located at the rear for lengthening rotary shaft 6；Toppled over when appointed place is transported to When, raise up handle 1, so that 4 center of gravity of wagon box deflection lengthens rotary shaft 6, now, wagon box 4 can be moved in front of which under gravity A dynamic segment distance, and the second linking arm 8 is driven around to 6 rear of lengthening rotary shaft, and then make 4 center of gravity of wagon box move forward, beneficial to wagon box 4 Overturn around its pin joint, it is spacing that the second linking arm 8 realizes activity in the presence of spacing lever 9；Slide block 10 and slideway 11 Cooperation promotes the relative movement of wagon box 4, while also functioning to stablize the effect of 4 body of wagon box.

Finally it should be noted that：The preferred embodiment of utility model is the foregoing is only, practicality is not limited to It is new, although being described in detail to utility model with reference to the foregoing embodiments, for a person skilled in the art, its Still the technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equal to Replace.It is all within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in reality Within new protection domain.
