Problems solved by technology

However, the square chassis of the trolley has four top corners of about 90 degrees, and when the top corners collide with objects, serious damage will be caused
If the top corner of the trolley hits the staff, it will also cause injury
In addition, the handle of the trolley is fixed to the chassis, so it is difficult to change the direction of movement of the trolley during use

Embodiment Construction

[0010] The trolley provided by the embodiment of the technical solution will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] Please also refer to figure 1 and figure 2 , is the trolley 10 provided by this technical solution, which includes a chassis 110 , casters 120 and pull rods 130 .

[0012] The chassis 110 is in the shape of a circular arc, such as an ellipse, a drop shape or other shapes with a circular arc, so as to prevent injury to other objects or workers. In this embodiment, the chassis 110 includes a carrying portion 111 located in the middle and an edge portion 112 surrounding the carrying portion 111 and connecting with the carrying portion 111 . The carrying portion 111 is used for carrying objects, and has a carrying surface 1111 for carrying objects and a bottom surface 1112 opposite to the carrying surface 1111 . The edge portion 112 protrudes from the carrying surface 1111 to prevent the items ...

Abstract

The invention provides a trolley, which comprises a chassis, a pull rod and castors, wherein the chassis has a circular arc outline and includes a first end part, a second end part opposite arranged to the first end part and a middle part connecting the first end part and the second end part, the first end part and the second end part all have circular arc outlines, a radius of curvature of the first end part is less than that of the second end part; the pull rod is rotatably connected to the first end part of the chassis and includes a pull rod body and a connector for the pull rod body and the chassis, the pull rod body includes an operation end and a fixing end, the pull rod body is a bending rod with an arc and the operation end is a ring handle; and the castors are arranged on the bottom surface of the chassis, and at least one castor is connected with the pull rod, so that at least one castor rotates along with the rotation of the pull rod to change the moving direction of the trolley. The trolley can lighten damage to articles and working staff caused by collision and is easy to change direction.

Description

technical field [0001] The present invention relates to a trolley, in particular to a trolley for transporting articles. Background technique [0002] Printed Circuit Board (Printed Circuit Board, abbreviated as PCB) is the main device for transmitting signals in electronic products such as computers and mobile phones, especially the flexible circuit with the advantages of small size, light weight, three-dimensional assembly and dynamic flexibility. Board, is more and more widely used in various portable electronic products, see literature Takao Yamazaki, Yoshimichi Sogawa, Rieka Yoshino, Keiichiro Kata, Ichiro Hazeyama, and Sakae Kitajo, Real Chip Size Three-Dimensional Stacked Package, IEEE Transactions on Advanced Packaging, 2005, 28(3), 397-403. [0003] In the PCB manufacturing process, it is usually necessary to frequently transport materials, PCB substrates or PCB products processed by different processes for use in the next process. At present, factories mostly use...
