Problems solved by technology

[0003] In the prior art, an elastic bottom plate is generally added at the bottom of the elevator box to relieve the human body impulse. This method not only increases the mass of the box, but also causes severe ups and downs due to the elastic potential energy when the elevator falls to the ground, which may cause damage to the human body. More serious damage, and the impact of falling from a high altitude is very huge, so in order to get a good cushion, the elastic force and elastic stroke of the elastic pad are required to be very large, so the elastic floor still has the disadvantage of taking up a lot of space; application number In the patent of 201420683390.2, the bottom is equipped with a daily retractable elastic pad to act as a buffer, and the inner wall is equipped with a safety belt to fix the human body, which can prevent the human body from moving in the box, but under a huge impact, the safety belt will also It will cause great harm to the human body. The bottom elastic pad that can really buffer the huge impact requires a lot of force to operate, so it is difficult to actually realize it. Can be used in time, so the operability is not strong
In the patents with application number 201620125409.0, application number 201610300929.5, application number 201610300956.2, and application number 201610300957.7, a device suitable for human body sitting or standing is added to the elevator box to buffer the impact force of falling, but the structure is complicated and it is not very convenient to use , it takes up too much space in a relatively narrow box and it is not economical, and once it falls, multiple parts in the box will also cause unexpected damage to the human body

Embodiment 1

[0038] Such as figure 2 , 4 As shown, the elastic member 13 is a spring 130, the sliding member 12 is provided with a sliding hole 120, and the guide post 141 on the guide member 14 passes through the spring 130 and the sliding hole 120, so that the spring 130 extends and contracts in the direction of the guide post 141, and the sliding member 12 Slide along the direction of the guide post 141 .

[0039] Such as image 3 Shown is a three-dimensional view inside the box of the embodiment of the present invention. The safety belt 11 fixed on the slider 12 exposed at the opening 20 on the box wall 23 can be seen from inside the box.

[0040] Such as Figure 4 Shown is a front view outside the box of the embodiment of the present invention. From the front view outside the box, it can be seen that a guide 14 is fixed outside the box wall 23, and the guide 14 is pierced with a slide 12 and arranged above and below the slide 12. The elastic member 13 includes two groups of springs...

Embodiment 2

[0042] Such as Figure 5 and Figure 6 Shown is the three-dimensional hierarchical view and the front view outside the box of Embodiment 2 of the present invention. The sliding member 12 includes a columnar slider 121 and a slide plate 122 for fixing the seat belt 11. The elastic member 13 is connected to the columnar slider 121, and guides Part 14 is a tubular guide sleeve, which can accommodate and match columnar slider 121 and elastic member 13, and slide block 121 can slide in the guide sleeve of guide member 14 and compress or stretch elastic member 13; Figure 6 As shown, when viewed from the outside of the box, the guide 14 and the slide plate 122 fixed on the outside of the box wall 23 can be seen.

[0043] Further, the elastic member 13 can be arranged under the sliding member 12, such as Figure 7 Shown; Elastic member 13 can be arranged on the upper position of sliding member 12, as Figure 5 Shown; Elastic member 13 can also be set at the upper and lower positio...

Abstract

The invention belongs to the technical field of elevators and relates to an elevator with a falling risk avoiding device. The elevator with the falling risk avoiding device is characterized by comprising a safety belt, a sliding piece, an elastic piece and a guiding piece; the safety belt is arranged on the sliding piece which can compress or stretch the elastic piece in the direction of the guiding piece; the guiding piece with the up-down guiding direction is fixedly arranged outside an elevator box; and the box wall is provided with an opening, so that the safety belt can be used in the box through the opening. When an accident fault happens to the elevator, passengers in the box can perform active defense through the safety belt, the effective buffering protection work is well done, and falling casualties and the panic mood are prevented. The elevator with the falling risk avoiding device has the beneficial effects of being simple in structure, small in size, small in weight, convenient and fast to operate, good in emergency meeting effect, free of occupying of the space in a lift car, capable of easily achieving large buffering stroke, good in buffering effect and capable of effectively preventing and controlling secondary injuries.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an elevator with a fall avoidance device. Background technique [0002] Many people have had the experience of being trapped in an elevator. When the elevator breaks down suddenly and the person is placed in a high place with more than ten floors or even dozens of floors, they will inevitably panic and panic, worrying that the elevator will lose control and fall rapidly. If it is long, it will exacerbate the spread of panic, cause emotional agitation, improper handling and other behaviors, and induce bigger problems. Generally speaking, elevators are a kind of equipment with high safety, but once an accident occurs, the people in the elevator cannot control it. This passive situation makes people always have a kind of fear in their hearts when taking elevators. , It is also a problem that we should solve. The best way is of course to give them a reliable protection tool for ac...
