The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a movable elevator with self-protection function comprises a movable plate 1, the movable plate 1 is made of stainless steel, which can effectively prevent equipment from being corroded, greatly prolongs the service life of the equipment, reduces the production cost, and plays an indispensable role for enterprises, a telescopic rod 2 is arranged above the movable plate 1, a receiving plate 3 is slidably connected to the top of the telescopic rod 2, a receiving wheel 5 is arranged inside the receiving plate 3, a clockwork spring ring is arranged inside the receiving wheel 5, when the inertia force disappears, the receiving plate 3 and the telescopic rod 2 are automatically restored to the initial position through the clockwork spring ring, a fixed rod 4 is engaged and connected to the surface of the receiving wheel 5, a clamping rod 6 is arranged below the receiving wheel 5, the clamping rod 6 and a delay plate 7 are engaged and driven upwards in one-way, so that after the receiving plate 3 and the telescopic rod 2 are restored to the initial position, the clamping rod 6 clamps the receiving wheel 5, a rotating head is arranged inside the clamping rod 6, when the clamping rod 6 is in meshing transmission with the delay plate 7, the clamping rod 6 is prevented from being clamped, the side surface of the clamping rod 6 is in meshing connection with the delay plate 7, the bottom of the clamping rod 6 is in rotating connection with a lever 8, the surface of the lever 8 is provided with a support rod, the left side of the lever 8 is in rotating connection with a push rod 9, the bottom of the push rod 9 is in sliding connection with a transition wheel 10, the surface of an inner wheel of the transition wheel 10 is provided with protrusions which are symmetrically distributed on two sides of the bottom of the push rod 9, the surface of the transition wheel 10 is in meshing connection with an inertial toothed plate 11, the side surface of the inertial toothed plate 11 is provided with a sliding rod 12 in an inserting way, the top of the bearing plate 3 is fixedly connected with a platform 13, the top of the platform 13 is provided with a support plate 14 in an inserting way, the bottom, can effectively prevent that equipment from being corroded, air tank 16 passes through pipe and air spring 15 intercommunication, when relative displacement appears in inertia air board 17 and air tank 16, draws air and aerifys air spring 15 through the pipe, and then adjusts the angle of backup pad 14, and the inside sliding connection of air tank 16 has inertia air board 17.

The working principle is that when the moving plate 1 at the bottom of the elevator moves, the telescopic rod 2 drives the bearing plate 3 and the platform 13 above the bearing plate to move synchronously, and because the initial movement is carried out, the whole elevator generates inertia force under the action of acceleration.

Under the action of inertia force, the inertia toothed plate 11 moves relative to the sliding rod 12 and generates meshing transmission with the transition wheel 10, when the transition wheel 10 rotates, the protrusion arranged on the surface of the inner wheel pushes the bottom of the ejector rod 9, the ejector rod 9 moves upwards, the left side of the lever 8 pushes upwards, due to the support rod arranged on the surface of the lever 8, the right side of the lever 8 moves downwards to drive the clamping rod 6 to move downwards, the clamping rod 6 is initially clamped in the clamping groove formed on the surface of the inner wheel of the bearing wheel 5, the clamping rod 6 moves downwards to separate from the clamping groove, the fixed rod 4 drives the telescopic rod 2 to generate meshing transmission with the bearing wheel 5 under the action of inertia force, namely, the telescopic rod 2 moves relative to the bearing plate 3, the platform 13 on the top of the bearing plate 3 synchronously moves in a staggered mode, and counteracts part of inertia force generated by the movement of the lifter, so that the influence of the inertia force on the platform 13 is weakened, the effect of preventing people or goods on the surface of the platform 13 from falling.
