Description

A kind of Portable draw bar dolly
Technical field
The invention belongs to goods carrying technical field, particularly to a kind of manpower transport's apparatus.
Background technology
Logistic industry is prevailing at present, has important effect in Working Life.Weight is big or volume cargo mostly is and consigns in batch, and its carrying and classification more specialty, the vehicle of outfit is the most complete.But express delivery industry type of goods is various, bulking value is uneven, if goods short distance to be transported in client's hands that local environment is different by courier, situation about facing is more complicated, aid that object uses is less to cause courier to send with charge free, and manpower expenditure is big, and labor intensity is big.Additionally, courier is restricted because sending the carrying space in condition with charge free, so being designed with folding mode to reduce volume, it is convenient for carrying.Further investigation reveals that, rod trolley or go-cart are favored by people because of small volume, light weight, feature that carrying is bigger widely as delivery and power assisting device, apply more and more extensive in life.But analyzing market feedback situation to learn, the folding class rod trolley that market is had exists some problems, as during folded state, volume is relatively big, folding and expanding is inconvenient, and bearing capacity is weak, and ground adaptation ability is weak.
China Patent Publication No. is a kind of Handling device of CN105314345A.Overhead transfer car possesses the clamping device holding box, carries the box held by clamping device.Overhead transfer car possesses the article storing portion receiving the box held by clamping device and has the convolution platen accepting the box held by clamping device from clamping device, and convolution platen makes box move to article storing portion from clamping device when having accepted from the box that clamping device is accepted.
This patent structure is complicated, and manufacture process is loaded down with trivial details, and volume is bigger, it is impossible to carry with.
Therefore, we devise a kind of volume little, easy to carry, can the auxiliary carrying device of fast folding and expansion.This rod trolley cannot only be applied to express delivery industry short distance transport, and goods is carried, and meanwhile, increases miscellaneous function by design beam mechanism, and device also can easily carry the article such as shopping bag, can promote the use of home shopping, aspect of travelling outdoors etc..This super folding pull rod dolly will alleviate the expenditure of manpower in the case of easy to carry greatly and reduce labor intensity, and audient crowd's area is big, be simultaneously fabricated into low, and market popularization value is high.
Summary of the invention:
It is an object of the invention to provide a kind of Portable draw bar dolly, the problem that it can efficiently solve folded state compact.
The present invention realizes its goal of the invention and be the technical scheme is that a kind of Portable draw bar dolly, including handle, expansion link, shelf bar, wheel, handle is fixed on expansion link upper end, expansion link lower end is fixed between front shoe and rear fixed plate, the top of front shoe and rear fixed plate is provided with crossbeam, and bottom is provided with brace;Being provided with fixed block below brace, the top of fixed block is connected by revolute pair with shelf bar, and the wheel shaft of lower section and wheel is fixed;One end of cross beam support bar is connected by revolute pair with crossbeam, and the other end is connected by revolute pair with slide block one;One end of brace support bar is connected by revolute pair with brace, and the other end is connected by revolute pair with slide block two;The middle part of rear fixed plate is provided with built on stilts little fixed plate, it is provided with connecting rod one therebetween, connection between the middle part of connecting rod one and rear fixed plate and little fixed plate is revolute pair, one end with connecting rod two respectively, the two ends of connecting rod one is connected by revolute pair, and the other end of connecting rod two is connected by revolute pair with middle part, the middle part of slide block two of slide block one respectively.
Described front shoe and both sides, rear fixed plate top are provided with the caging bolt of expansion link.
Described crossbeam is connected by revolute pair with between front shoe and rear fixed plate.
Described brace is connected by revolute pair with between front shoe and rear fixed plate.
Work process and the principle of the present invention be:
When needs carrying article, first rotate both racks bar to extreme position, rotate brace, make it rotate around the bottom of forward and backward fixed plate, drive brace support bar to make slide block two slide downward, make connecting rod one rotate to vertical position by connecting rod two, slide block one moves upward simultaneously, cross beam support bar rotates around slide block one, drives crossbeam to rotate to extreme position around the top of fixed plate, it is achieved self-locking.Last pull handle makes expansion link stretching open and lock, and now this dolly is duty, can carry article.
When making to be finished this dolly and needing to be packed up, first being packed up by expansion link, both hands make slide block one slide downward one segment distance, it is made to release self-locking state, then rotating brace, brace drives brace support bar so that slide block two moves upward, rotated by connecting rod two drivening rod one, slide block one moves downward, and makes crossbeam turn to the position parallel with expansion link around fixed plate top by cross beam support bar, and now brace is also parallel with expansion link, finally rotate shelf bar, complete to shrink.
Compared with prior art, the invention has the beneficial effects as follows:
One, portable folding rod trolley, volume is little, lightweight, and after folding, volume is only 340mm*120mm*28mm, can easily put in various bag, be convenient for carrying.
Two, multistage linking linkage rod slide block mechanism a, it is possible to achieve step of mechanism is opened and closed, simple to operation.
Three, by the design of mechanism size is calculated, make dexterously be positioned at dead-centre position during multistage linking mechanism deploying and realize self-locking, complete to launch location, solid and reliable, convenient and swift.
Four, the satchel made to measure for device can make device transport big part express delivery and multiple smallclothes express deliveries, and using method is various, and range is extensive.
