a portable carrier

Abstract

The present invention provides a portable conveyor and relates to the technical field of conveying machinery. Two ends of two parallel vertical bars I are fixed to the two ends of a cross bar I, to form a parallelogram frame, two ends of a cross III are fixed to the middles of the vertical bars I, and truckles are arranged at the bottoms of the vertical bars I; a pair of supporting seats are arranged at the upper and lower parts of the vertical bars I on the front of the parallelogram frame, two cross shafts are fixed to the vertical bars I through the supporting seats, a pair of arm lock bars are fixed to the cross shaft through opened sockets at an interval and two springs are arranged between the two arm lock bars; one end of each spile is provided with a cantilever, the other end of each spile is hinged to the lower end of the corresponding arm lock bar, and the middles of the spiles are hinged to the arm lock bars through struts; a pedal rotating clamping mechanism is connected with a vertical bar II through a revolute pair; the middle of the vertical bar II and the middle of an oblique connection rod I are also connected by a revolute pair, the middle of the oblique connection rod I is riveted and fixed to the top of an oblique connection rod II, and the right end left ends of the oblique connection rod I are connected with an oblique connection rod III through another revolute pair. The portable conveyor is used for manually conveying box objects.

Description

Technical field [0001] The present invention relates to the technical field of handling machinery, in particular to a handling machinery device. Background technique [0002] In recent years, due to the improvement of people's living standards and the continuous development of shopping websites, the phenomenon of online shopping has become more and more common. China's express delivery industry has seized the opportunity and achieved rapid expansion. Statistics show that China’s express delivery business volume reached 14 billion pieces last year, becoming the world’s number one. It has increased by more than 50% for four consecutive years. According to incomplete statistics, the number of couriers in China exceeds two million, with an average of each courier per day. It is necessary to deliver fifty or sixty express items. How to help the courier deliver the items more labor-saving and ensure the safety of the goods has become an important proposition. [0003] There is no shorta...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned invention needs to be driven by hydraulic pressure, which consumes energy; it can only realize the lifting of objects, and has a single function; it is too heavy to be carried around

[0008] Therefore, it is necessary to design a power-assisted device so that couriers can easily carry items without bending over, solve the problem of not being able to find a point of focus when carrying large items, and at the same time ensure the handling efficiency, so that the device can be truly accepted and used by the majority of couriers
