Detailed Description

As shown in fig. 1, a protection structure in an elevator comprises a car 1, wherein the car 1 is arranged in an elevator shaft 5, more than one through hole is formed in the inner wall surface of the car 1, a step surface is arranged at the inner side end of each through hole, an elastic rod 11 penetrates through each through hole, a hollow cavity is arranged in each elastic rod 11, one end, far away from the car, of each hollow cavity is opened and is filled with an elastic telescopic rod 14, a first spring 21 is fixedly arranged in each hollow cavity 2, one end of each first spring 21 is fixedly connected with the bottom surface of the corresponding hollow cavity, the other end of each first spring 21 is fixedly connected with the end surface of the corresponding elastic telescopic rod 14, and the elastic telescopic rods 14 are ejected outwards through the first;

an air guide branch pipe 13 is connected to the outside of each elastic rod 11, the air guide branch pipes 13 are connected and communicated with the elastic rods 11, a positioning component is arranged in each air guide branch pipe 13, a positioning hole (not shown) is formed in the position, opposite to the positioning component, of the outer side end of each elastic telescopic rod 14, the positioning component is positioned and arranged in each positioning hole, the elastic telescopic rods are limited to be ejected out of the elastic rods, and the first springs 21 are compressed;

an outer protection plate 7 is arranged on the outer portion of the car 1 corresponding to the position of the elastic rod 11, the outer protection plate 7 is elastically connected with the car 1, and one end of the outer protection plate 7 is fixedly contacted with one end of the elastic rod 11.

One end of the air guide branch pipe 13 is connected with an air guide main pipe 12, the air guide main pipe 12 is connected and communicated with the air guide branch pipe 13, one end of the air guide main pipe 12 is buckled into the car 1, the outer end of the air guide main pipe is sealed by a threaded sealing plug 8, and a warning slogan, such as 'no emergency state forbids opening' and the like, can be pasted on the car outside the threaded sealing plug. When the positioning device is installed, high-pressure gas is filled into the gas guide main pipe, so that the positioning component is always positioned and installed in the positioning hole of the elastic telescopic rod. In this embodiment, the main air guide duct and the branch air guide duct may be flexible ducts without elastic expansion capability.

As shown in fig. 4, the positioning assembly includes a positioning post 22 disposed in the air guide channel of the air guide branch pipe 13, a sealing piston 23 is disposed on the positioning post 22, the sealing piston 23 is partially buckled in a guide groove formed in the inner wall of the air guide channel 24, a second spring 25 is disposed in the guide groove, the top of the second spring 25 is in contact with the sealing piston 23, the bottom of the second spring is in contact with the bottom surface of the guide groove, and the bottom of the positioning post 22 is partially buckled in the positioning hole of the elastic telescopic rod 14.

The protection plate is arranged outside and used as elastic buffering of the elastic rod, when an object in the car impacts the inner wall surface of the car, the protection plate is firstly contacted with the elastic rod and then pushed out of the elastic rod, so that the outer protection plate is pushed out, and the third spring is stretched to achieve the purpose of elastic buffering.

In this embodiment, as shown in fig. 2, a sealing cover plate 3 is disposed at one end of the elastic rod 11 located in the car, the sealing cover plate 3 is buckled in the step surface for positioning and assembling, when the building is in the decoration peak period, the elastic rod is pushed out by the outer protection plate and located in the car for buffering, and when most of the decoration is finished or finished, the outer protection plate can be removed by a worker, and a third spring, at this time, each elastic rod can be pushed out outwards, so that the sealing cover plate is buckled in the step surface, at this time, the inside of the whole car returns to the original state, and there is no sense of concavity and convexity.

Wherein, top-down is provided with buffer block 4 more than on 5 internal surfaces of elevartor shaft, and the up end of buffer block 4 is an inclined guide surface, and when elasticity telescopic link 14 ejecting back, car 1 is when descending, and the inclined guide surface contact on 14 parts of elasticity telescopic link and the buffer block 4, and more than one elastic rod passes through the outside outer protection shield of car spacing for more than one elastic rod part stretches into in the car inner space, and forms the elasticity protective layer in the car. When the elevator takes place urgent out of control and falls, at this moment, the staff who is located the car inside can take off the screw sealing plug, the high-pressure gas in air duct and the air guide branch pipe at this moment runs out, there is not atmospheric pressure at reference column and sealing piston top this moment, this moment under the second spring action, the reference column resets, elastic telescopic rod loses the location fixed force this moment, under first spring action, elastic telescopic rod is ejecting to the outside, as shown in figure 3, the elastic telescopic rod that is ejected out this moment can be when descending with the slope spigot surface contact on the buffer block, a falling speed for reducing the elevator, promote the security of elevator greatly.

The invention has the beneficial effects that: the elevator car is internally provided with more than one telescopic elastic rod, the elastic rods distributed all over are used for protecting the inner wall surface of the car, damage caused by collision of transported objects on the inner wall of the car is prevented, safety is improved, meanwhile, the elastic rods cannot increase the internal space of the elevator, and the elastic rods can be extruded to retreat, so that more goods are placed.

In addition, the elastic rods can be opened in emergency, and are used for reducing the speed of the elevator when the elevator descends rapidly, so that the use function of the elastic rods is increased, and the elevator is safer to use.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
