The invention provides a self-locking wheel stopper, and the wheel stopper comprises a bottom plate, an inclined sealing plate, a vertical sealing plate, a pedal plate, a rib plate and a vertical plate which are connected with one another; a shaft sleeve is fixedly installed on the vertical plate, a square shaft is rotatably installed in the shaft sleeve in a matched mode, and a triangular key hole is formed in the shaft end of the square shaft. The shaft body of the square shaft is coaxially and fixedly connected with the middle part of the pawl to drive the pawl to rotate in a vertical plane; the lower part of the pawl is provided with an arc bulge; the vertex of the square ratchet is fixedly connected with one end of a return spring; the other end of the return spring is fixedly connected with the vertical plate; when the return spring is in a natural return state, the square ratchet and the clamping groove of the self-locking device are locked in a matched mode; when the pawl rotates and the square ratchets retreat from the clamping grooves in the top ends of the self-locking devices, the supporting plates fixedly connected with the arc protrusions of the pawl open the self-locking devices, and the self-locking devices are opened. The wheel stopper is firm and stable in structure, large in locking force, small in error, compact in structure and capable of effectively preventing theft and achieving anti-slip; the accident rate is reduced; no quick-wear part exists, and the service life is long; and a more reliable anti-theft effect and a safe anti-slip effect can be achieved.

    提供一种自锁止轮器,包括底板、斜封板、竖直封板、踏面板、筋板和立板相连;立板固定安装轴套,轴套内转动适配安装方轴,方轴轴端制有三角钥匙孔;方轴轴体同轴固连棘爪中部带动棘爪在竖直平面内转动;棘爪上部制有方形棘齿,下部制有圆弧凸起;方形棘齿顶点固连回位弹簧一端;回位弹簧另一端与立板固连;回位弹簧自然回位状态下,方形棘齿与自锁装置卡槽适配锁止;棘爪转动且其方形棘齿退出自锁装置顶端卡槽时,棘爪圆弧凸起固连的撑板撑开自锁装置,自锁装置打开。本发明通结构牢固稳定,锁止力大,误差小,结构紧凑,可有效防盗,实现防溜;降低事故发生率;无易损件,寿命持久;可起到更加可靠的防盗作用和安全防溜作用。
