一种网球捡球车

Abstract

本实用新型公开一种网球捡球车，涉及网球设备技术领域，包括推杆装置，推杆装置的上方设置把手，移动装置连接导向装置，导向装置设置在网球捡球车的前端，储球装置A设置在导向装置上且连接移动装置，储球装置A的下方为收球空间，进球装置内置在移动装置内，进球装置的送球区域分别限制在滚轮位置形成两个短筒式分散收球结构，每次最多存在2个网球在摩擦轮底部被同时挤压，从而减少捡球车的自重，为捡球车的轻量化、便携化提供有利条件，且推拉更省力，阻力反馈更平稳，手柄反馈的阻力变化幅度小，有效避免了明显的顿挫感，取球过程更流畅。双独立单球进入通道在结构的设计上会更为简单，不会因为转弯问题而使得移动装置结构复杂化。
