Folding ball trolley

Abstract

A folding ball trolley has a frame and a bag. The frame has two main rod assemblies and two connecting rod assemblies. When the folding ball trolley is expanded, the main rods and the connecting rods lean outward under gravity until the main rods brace the bag. The bag holds the main rods at a specific angle, and the main rods hold the connecting rods at a specific angle. The main rod assemblies and the connecting rod assemblies are connected into a rectangle, such that the frame is expanded horizontally when the rods are leant outward. Thus, the folding ball trolley can achieve auto expansion without any resilient element, and therefore a user does not have to resist the resilient force when folding. Besides, the amount of the rods is reduced to eight (four main rods and four connecting rods), which reduces the manufacturing cost and facilitates ease of assembly.

Description

technical field [0001] The invention relates to a ball cart capable of placing and moving various balls such as basketballs and volleyballs. Background technique [0002] A golf cart is a kind of cart commonly found in gymnasiums and other places. Multiple balls can be placed on it, so that the user can easily move multiple balls, or during practice, the user can constantly move from the cart to the side. Get the sphere to use. [0003] Golf carts of the prior art, such as China Taiwan Bulletin No. M459001 "The golf cart that can reduce the folded volume", please refer to Figure 12 As shown, it includes a frame 91, a bag body 92 and two springs, and the frame 91 includes four vertical rods 911, four top pivot seats 912, four sliding pivot seats 913, four connecting rod groups 914 and four support rods 915 The four top pivot seats 912 are respectively arranged on the tops of the four vertical bars 911; the four sliding pivot seats 913 are respectively slidably arranged on t...

AI Technical Summary

Problems solved by technology

[0005] First, the number of components is large, among which the four vertical rods 911, the four connecting rod groups 914 and the four supporting rods 915 contain a total of sixteen rod bodies, which not only leads to an increase in production costs, but also takes more time for assembly

[0006] Second, a spring needs to be installed to maintain the unfolded state of the golf cart, but this not only leads to increased cost and troublesome assembly, but also needs to resist the elastic force of the spring when the golf cart is to be folded, thus causing inconvenience

[0007] Third, when the golf cart is folded or unfolded, each sliding pivot seat 913 will slide relative to the upright rod 911, and this sliding action may not be smooth due to various reasons, such as insufficient fine workmanship during production, long-term use, etc. Rust or angle deviation due to impact, etc., and poor sliding will make it difficult to fold or unfold the cart
