The invention provides a novel door positioner. The novel door positioner comprises a front cover, a base and an axle, the front cover comprises a plurality of front cover grooves, a plurality of front cover supporting columns, a plurality of front cover groove sawtooth plates and a plurality of pairs of front cover clamping grooves; the base comprises a plurality of base grooves, a plurality of base supporting columns, a plurality of clutch springs and a plurality of base groove sawtooth plates; and the axle comprises a plurality of coaxial fixed wheels, a plurality of coaxial first gears, a plurality of coaxial second gears, a plurality of axle first annular grooves, a plurality of axle second annular grooves, an axle first clamping column, an axle second clamping column, a plurality of axle first annular groove hoops, a plurality of axle second annular groove hoops, a plurality of axle first power springs and a plurality of axle second power springs. A door can be positioned at a certain fixed position, and even if the external force is increased, the static friction force between the door and the ground can be quickly larger than the external force, so that the door can only be positioned at a certain position after small-amplitude rotation.
一种新型门定位器包括：前盖，所述前盖包括若干个前盖凹槽，若干个前盖支撑柱，若干个前盖凹槽锯齿板，若干对前盖卡槽；底座，所述底座包括若干个底座凹槽，若干个底座支撑柱，若干离合弹簧，若干个底座凹槽锯齿板；轮轴，所述轮轴包括若干同轴固定轮，若干同轴第一齿轮，若干同轴第二齿轮，若干轮轴第一环状凹槽，若干轮轴第二环状凹槽，轮轴第一卡柱，轮轴第二卡柱，若干轮轴第一环状凹槽卡箍，若干轮轴第二环状凹槽卡箍；若干轮轴第一动力弹簧，若干轮轴第二动力弹簧。本发明可以使门定位在某一个固定的位置，即使外力变大，也可以快速使本发明与地面的静摩擦力大于外力，使门只能发生小幅度的转动后定位在某一位置。
