Abstract

A locating structure of a handcart includes a main frame, two side rods and a locating rod. The main frame includes a pair of longitudinal rods. The two side rods are pivotally connected to the longitudinal rods of the main frames, respectively. Each side rod has a stop section which is spaced from the longitudinal rod. The locating rod is pivotally connected to the main frame. The locating rod has a pair of extension sections to engage with the stop sections of the two side rods when the two side rods and the locating rod are unfolded.

Claims

1. A locating structure of a handcart, comprising:

a main frame comprising two longitudinal rods;

two side rods pivotally connected to the two longitudinal rods of the main frame, each of the side rods having a stop section which is spaced from the relative longitudinal rod of the main frame; and

a locating rod pivotally connected to the main frame, the locating rod having a pair of extension sections;

thereby, when the side rods and the locating rod are unfolded, the pair of extension sections engaging with the stop sections of the two side rods.

2. The locating structure of a handcart as claimed in claim 1, wherein the main frame further comprises a transverse bar connected between the two longitudinal rods, the stop section being a curved section, each of the two side rods further having an upper section and a lower end, the upper sections and the lower ends of the two side rods being pivotally connected to the two longitudinal rods of the main frame respectively, the locating rod comprising a stop plate to engage with the transverse bar of the main frame when the locating rod is unfolded.

3. The locating structure of a handcart as claimed in claim 1, wherein each of the side rods further has an upper section and a lower end, the stop section is located between the upper section and the lower end, the upper sections and the lower ends of the two side rods being pivotally connected to the two longitudinal rods of the main frame respectively, the stop section having a curved portion and a horizontal portion, the horizontal portion being provided with a stop block, the locating rod being pivotally connected to the two longitudinal rods of the main frame, when the locating rod is unfolded, the locating rod engaging with the stop block.
