The invention discloses a quick release device for a pedal. The quick release device comprises an outer sleeve piece, an inner sleeve piece, a clamping piece and an elastic piece, the outer sleeve piece comprises a sleeve hole; the inner sleeve piece is inserted into the sleeve hole and connected to the driving handle, the inner sleeve piece comprises a shaft hole and a radial hole communicated with the shaft hole, and the pedal mandrel is inserted into the shaft hole; the clamping piece is arranged on the outer sleeve piece and is inserted into the radial hole; the elastic piece elastically abuts between the outer sleeve piece and the inner sleeve piece in the radial direction, so that a radial movement margin exists between the inner sleeve piece and the hole wall of the sleeve hole; when the pedal mandrel is inserted into the shaft hole, the outer sleeve piece is located at the locking position. In the axial direction, the clamping piece and the radial flange of the pedal mandrel have an overlapping scale and axially stop the radial flange, and the overlapping scale is not larger than the radial movement margin. When the outer sleeve piece radially moves to a release position relative to the inner sleeve piece; and in the axial direction, the clamping piece is not overlapped with the radial flange, so that the pedal mandrel can be separated from the inner sleeve piece. The invention discloses a quick release device for a pedal, which can be used for quickly dismounting and mounting the pedal and reliably buckling the pedal, and has high safety.
本发明公开了一种踏板快拆装置,包括:外套件、内套件、卡件、弹性件;外套件包括套孔;内套件插设于套孔且连接至驱动柄,内套件包括轴孔和连通轴孔的径孔,踏板心轴与轴孔插接;卡件设于外套件且插设于径孔;弹性件径向弹抵于外套件和内套件之间,使内套件与套孔的孔壁之间存在径向活动裕度;其中,当踏板心轴插接于轴孔且外套件位于锁定位置;沿轴向方向,卡件与踏板心轴的径向凸缘具有重叠尺度而轴向止挡径向凸缘,重叠尺度不大于径向活动裕度;当外套件相对内套件径向移动至位于释放位置;沿轴向方向,卡件不与径向凸缘重叠,使踏板心轴能脱离内套件。本发明公开一种踏板快拆装置,能快速地拆装踏板,且能可靠地扣接踏板,具有高安全性。
