Portable fence
The invention discloses a portable fence. The portable fence comprises a storage supporting cylinder and a connecting supporting column, wherein a hole is formed in the side wall of the storage supporting cylinder; a winding shaft is rotationally arranged in the storage supporting cylinder; a protective net connected with the connecting supporting column is fixedly connected to the winding shaft;two mounting grooves are formed in the inner wall of the hole; a fixed scraping block penetrating into the hole is fixedly arranged in one mounting groove; a movable scraping block is arranged in theother mounting groove in a sliding mode; a one-way transmission mechanism is arranged between the winding shaft and the movable scraping block; a setting groove is formed in the inner wall of the storage supporting cylinder; the one-way transmission mechanism comprises a ratchet and pawl structure and a rack connected with the inner wall of the setting groove in a sliding mode; the side wall of the rack is connected with the movable scraping block through a transmission rod; one side of the rack is meshed with a gear; and the gear is connected with the ratchet and pawl structure through a belttransmission structure. Compared with the prior art, the portable fence is small in occupied space after being disassembled, and waste residues attached to the surface of the protective net can be quickly removed.
本发明公开了一种便携式围栏，包括收纳支撑筒和连接支撑柱，收纳支撑筒侧壁上穿孔，收纳支撑筒内转动设置收卷轴，收卷轴上固定连接有与连接支撑柱连接的防护网；穿孔的孔内壁上开有两安装槽，其中一个安装槽内固定设置有穿入至穿孔内的定刮料块，另外一个安装槽内滑动设置有动刮料块，收卷轴与动刮料块之间设置有单向传动机构；所述收纳支撑筒内壁上开有设置槽，单向传动机构包括棘轮棘爪结构以及与设置槽内壁滑动相连的齿条，齿条侧壁通过传动杆与动刮料块相连，齿条的一侧啮合有齿轮，齿轮与棘轮棘爪结构通过带传动结构相连；本发明与现有技术相比，拆分后占用空间小，且能够快速将粘附在防护网表面的废渣清理掉。
