Logistics trolley

Abstract

The invention discloses a logistics trolley and belongs to the technical field of logistics transportation facilities. The logistics trolley comprises a base, a left railing, a right railing, a goods bearing base plate, goods aerial joist plates and a transverse top rod. The logistics trolley is characterized by further comprising a front railing door and a rear railing door, and the left side of the rear railing door is connected with the rear side of the left railing in a pivoted mode; the right side of the rear railing door forms a free side and provided with a rear railing door opening and closing mechanism; the right side of the front railing door is connected with the front side of the right railing in a pivoted mode; the left side of the front railing door forms a free side and provided with a front railing door opening and closing mechanism; the base is in the shape of a Z. The logistics trolley can be converted between two walls or three walls or four walls as required to meet the flexible change requirements of goods with different sizes during carrying and transferring. The ideal bearing strength and the connection effects on the left railing and the right railing are ensured, so that deformation and even shattering are avoided. The occupied space is reduced, and separation and collapse are avoided. The structure is simple, and operation is convenient. Selective conversion between the two walls or the three walls or the four walls is very fast and convenient. The good exhibition function to the goods is achieved.

Description

technical field [0001] The invention belongs to the technical field of logistics transportation facilities, and in particular relates to a logistics trolley. Background technique [0002] The logistics trolley is a simple tool for storing, loading, unloading, carrying and displaying goods and playing the role of displaying goods and promoting them. It is widely used in warehousing and logistics industries and can also be used for finished or semi-finished products between processes in industrial enterprises. turnover. [0003] In the published Chinese patent literature, it can be seen that all the technical information about the logistics trolley, such as the invention patent application publication number CN103448767A, recommends a "plastic floor logistics trolley" (three-sided enclosure structure), which consists of the bottom plate, left and right columns and the rear column. In the state of use, the left column and the right column are expanded to a state perpendicular ...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies in the above patents are made up by the "two-door logistics trolley" provided by the invention patent application publication number CN104442950A. For details, please refer to paragraphs 0005, 0008 and 0018 of the specification of CN104442950A, but CN104442950A will show in the actual use process The following shortcomings: First, due to the structure of two walls (the patent is called two doors) arranged face to face, there is a phenomenon of taking care of one thing and losing the other. Loading and transshipment requirements of goods, the so-called loss means that when carrying small-sized goods, it is easy to escape from the open parts on both sides to the floor, causing pollution and / or damage; The structure is composed of a first folding guide rail and a second folding guide rail hinged to each other. Therefore, although the folding requirements in the storage state can be met, the production and assembly of the front and rear folding mechanisms are more troublesome, and the connection and support of the front and rear folding mechanisms to the two walls The strength is very fragile (for details, please refer to paragraphs 0028 to 0029 and paragraph 0037 of the specification of the patent application); thirdly, there is no mutual traction between two adjacent logistics trolleys when they are stored and stored in a standby state. Therefore, it is easy to cause separation and disintegration between each other; fourth, because the switching operation between unfolding and storing is more troublesome, it brings inconvenience to users
