The invention relates to the technical field of wheel body telescopic devices, and provides a telescopic wheel mechanism and a box body. Wherein the telescopic wheel mechanism is provided with a connecting groove extending in the first direction, the pull rod is provided with a connecting column, the connecting column is slidably arranged in the connecting groove, and the pull rod can rotate around the connecting column relative to the mounting base; the wheel body assembly is rotationally arranged on the mounting seat and has an extending position and a retracting position for extending out of and retracting the mounting seat; the limiting rod piece is connected between the pull rod and the wheel body assembly, a positioning groove is formed in the mounting base, the limiting rod piece is in sliding fit with the positioning groove, and the limiting rod piece has a locking position and an unlocking position in the positioning groove; the pull rod rotates around the connecting column relative to the mounting base so as to drive the limiting rod piece to be switched between the locking position and the unlocking position, and when the limiting rod piece is located at the unlocking position, the pull rod slides in the first direction relative to the mounting base so as to drive the wheel body assembly to be switched between the stretching-out position and the retracting position, so that the pull rod conveniently controls stretching out, drawing back and locking of the wheel body assembly.
本公开涉及轮体伸缩装置技术领域,提供一种伸缩轮机构及箱体。其中伸缩轮机构设有沿第一方向延伸的连接槽,拉杆上设有连接柱,连接柱滑动设置于连接槽内,且拉杆能够绕连接柱相对安装座转动;轮体组件转动设置于安装座上,轮体组件具有伸出和收回安装座的伸出位置和收回位置;限位杆件连接于拉杆和轮体组件之间,安装座上设有定位槽,限位杆件与定位槽滑动配合,限位杆件在定位槽中具有锁定位置和解锁位置;拉杆绕连接柱相对安装座转动,以带动限位杆件在锁定位置和解锁位置之间切换,且限位杆件处于解锁位置时,拉杆相对安装座沿第一方向滑动以带动轮体组件在伸出位置和收回位置之间切换,使拉杆便捷的控制轮体组件的伸缩和锁定。
