Novel insulating telescopic herringbone ladder
The invention discloses a novel insulating telescopic herringbone ladder which comprises a front ladder assembly, a rear ladder assembly and a movable connecting rod assembly. According to the device, the one-key switch folding function of the extension ladder is achieved through the locking mechanism, tedious operation is avoided, meanwhile, the opening and closing state of the ladder can be clearly seen through the visible lamp, and the herringbone ladder is folded through the movable connecting rod assembly; 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 cup is reduced, the pressure intensity is increased, the rubber cup tightly abuts against the pipe wall to prevent air from leaking to the position above the piston, the effect of slow descending when the telescopic ladder is retracted is achieved through air resistance, hands and feet of a user are prevented from being injured by a ladder pedal, and the telescopic ladder is safe, reliable, reasonable in structure, telescopic, small in size after being retracted and convenient to use. And carrying and transportation are easy.
本发明公开了一种新型的绝缘伸缩人字梯，包括前梯组件、后梯组件和活动连杆组件；本装置通过锁固机构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，活动连杆组件将人字梯折叠；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，结构合理，具有伸缩特性，收缩后体积小，易于携带与搬运。
