Connecting piece and transmission unit and transmission device using the same

Abstract

The invention relates to a connecting piece, a transmission unit and a transmission device which use the connecting piece. The connecting piece comprises a first connecting rod a, a first connecting rod b, and a second connecting rod, wherein the first connecting rod a and the first connecting rod b are arranged in a mutual crossing manner; the included angle between the first connecting rod a andthe first connecting rod b is adjustable; one end of the second connecting rod is movably connected to one end of the first connecting rod a; and the other end of the second connecting rod moves up and down along a straight line along with the change of the included angle between the first connecting rod a and the first connecting rod b. When the vertical angle of a transmission platform and a support changes, the connecting piece does not give thrust to the support, so that the support can be kept moving vertically.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a connecting piece, a transmission unit and a transmission device using the connecting piece. Background technique [0002] In the logistics industry outlets, due to the small footprint of the logistics outlets, the large number of operators, and the complex site conditions, the equipment that can be put into use requires greater flexibility and convenience. [0003] There is a kind of foldable logistics transmission equipment on the market, which is widely used in various logistics online stores, but this kind of equipment intelligence can only be applied to the occasions where the ground is flat or the ground slope is small and changes continuously; many logistics outlets currently have ladder heights Changes, such as stairs with a large slope, need to transport goods across the stairs. The existing equipment can only be transported after the transmission plane is stretched in one...

Problems solved by technology

[0003] There is a kind of foldable logistics transmission equipment on the market, which is widely used in various logistics online stores, but this kind of equipment intelligence can only be applied to the occasions where the ground is flat or the ground slope is small and changes continuously; many logistics outlets currently have ladder heights Changes, such as stairs with a large slope, need to transport goods across the stairs. The existing equipment can only be transported after the transmission plane is stretched in one horizontal direction, and cannot adapt to the environment where the transmission plane has displacements in both horizontal and vertical directions. , in order to complete the cargo transportation in this special scene, we can only increase the human input, which makes the labor intensity of loading and unloading, logistics transmission, etc. very inconvenient
