Novel insulating telescopic straight ladder
The novel insulating telescopic straight ladder comprises a plurality of ladder column units which are arranged from bottom to top in an array mode, and each ladder column unit comprises a pedal, a fixing ring and a ladder column body; the one-key switch folding function of the extension ladder is achieved through the push rod and the trigger, tedious operation is avoided, and meanwhile the opening and closing state of the ladder can be clearly seen through the visible lamp; when the ladder column body is pulled upwards, the volume of air below the trapezoidal rubber bowl is increased, the pressure intensity is reduced, and air above the fixing ring is squeezed to the lower part from the periphery of the rubber bowl; the opening is easy; when the telescopic ladder is retracted downwards, the volume of air below the rubber bowl is reduced, the pressure intensity is increased, the rubber bowl tightly abuts against the pipe wall to prevent the air from leaking to the position above the piston, the effect of slowly descending when the telescopic ladder is retracted is achieved through air resistance, hands and feet of a user are prevented from being injured by ladder pedals, and the telescopic ladder is safe and reliable.
本发明公开了一种新型的绝缘伸缩直梯，包括若干个自下而上阵列设置的梯柱单元，所述梯柱单元包括踏板、固定环以及梯柱本体；本装置通过推杆及扳机实现伸缩梯的一键开关收合功能，告别繁琐操作，同时可视灯能清晰的看到梯子的开合状态；固定环内的向下凹的梯形橡皮碗，在梯柱本体被向上拉的时候，梯形橡皮碗下方的空气体积增大，压强减小，固定环上方的空气就从橡皮碗四周挤到下方；使打开时较为轻松；向下收的时候，橡皮碗下方空气体积缩小，压强增大，使橡皮碗紧抵着管壁不让空气漏到活塞上方，通过空气阻力实现了伸缩梯收回时的缓慢下降的效果，防止使用者的手脚被梯子踏板砸伤，安全可靠。
