The invention discloses a self-locking type gravity trundle carrier structure, and aims at providing the self-locking type gravity trundle carrier structure which can automatically lock a trundle and needs manual operation to unlock the trundle. The device comprises supporting plates, trundles and a control plate, the trundles are rotationally connected with the supporting plates, the two ends of the control plate are connected with the two supporting plates respectively, the two ends of a control cavity in the control plate are communicated with movable cavities in the two supporting plates respectively, a warping plate is movably connected with semicircular blocks in the movable cavities, and a pressing block and two pushing blocks are arranged in the control cavity. Protection blocks are installed on the left side and the right side of each trundle, a sliding groove where a plurality of inserting holes are evenly distributed is formed in one face of each protection block, an inserting block and a first spring are arranged on each warped plate, and the inserting blocks penetrate through the supporting plates to be movably connected with the sliding grooves. The self-locking caster has the beneficial effects that the purposes that the caster can be automatically locked, and manual operation is needed for unlocking can be achieved; replacement of the protection block is facilitated; the effect that the insertion blocks are smoothly inserted into the insertion holes is achieved.

    本发明公开了一种自锁式重力脚轮轮架结构,旨在提供了一种可自动锁死脚轮且解锁需手动操作的自锁式重力脚轮轮架结构。它包括支撑板、脚轮和控制板,脚轮与支撑板转动连接,控制板两端分别与两个支撑板连接,控制板内控制腔的两端分别与内两个支撑板内活动腔连通,翘板与活动腔内半圆块活动连接,控制腔内设有按压块和两个推块,推块的一端与按压块活动连接另一端与翘板的一端相接触,脚轮的左右两侧均安装有保护块,保护块的一面设有均匀分布有若干个插孔的滑槽,翘板上设有插块和弹簧一,插块穿过支撑板与滑槽活动连接。本发明的有益效果是:可达到可自动锁死脚轮且解锁需手动操作的目的;利于保护块的更换;拥有让插块顺利插入插孔的效果。
