Abstract

A safe damping air-bag cushion used in an elevator has the shape like an inner bottom plate of the elevator, and the size of the cushion is slightly smaller. A blast pipe extending out of the elevator is arranged on an edge close to the interior; a one-way valve, a valve seat, a one-way valve spring and a spring retaining pin are arranged in the blast pipe; and the air intake of the blast pipe takes the shape of an upside-down trumpet. When the elevator is out of control and falls freely in an accident, and the accelerated speed is equal to or larger than 9.8 m/s2, the air-bag cushion arranged on the elevator bottom plate and under passenger feet can be filled with air automatically, so as to play the roles of cushioning and damping at the moment the elevator reaches the ground, and further reducing injury to passengers.

Description

Safety and shock-absorption air bag cushion of elevator

Affiliated technical field

The utility model relates to a kind of safety and shock-absorption air bag cushion of elevator.

Background technology

At present, the elevator used at the high-rise building of usefulness all exists potential safety hazard, in case the free-falling body that is out of control for some reason drops, will cause the personnel's that take a lift injures and deaths when elevator, and how reducing and eliminating kind of a potential safety hazard is a current difficult problem.

Summary of the invention

In order to address the above problem, the utility model provides a kind of safety and shock-absorption air bag cushion of elevator, this safety and shock-absorption air bag cushion of elevator is at elevator when the acceleration/accel of free fall out of control is equal to and greater than 9.8m/s2 for some reason, the air cushion that is located at passenger underfooting on the elevator base plate is with automatic topping-up gas, when elevator contacts to earth, play the bumper and absorbing shock effect, thereby reduce passenger's damage.

The purpose of this utility model is to realize like this, a kind of safety and shock-absorption air bag cushion of elevator, its shape size is identical with the elevator tank top plate, undersized, be provided with blast pipe extends outside the elevator on the limit near the inside, be provided with individual event valve in the blast pipe, valve seat, check valve spring, the spring backing pin, it is horn-like that the ventilation inlet of blast pipe is back-off, at ordinary times, check valve in the blast pipe seals blast pipe under action of the spring, no air safety and shock-absorption air bag cushion of elevator is as same Zhang Putong pad in the air bag cushion, pad is layered on the interior floor of elevator, when abnormal tenesmus appears in elevator, the acceleration/accel of its decline is near the moment of 9.8m/s2, overcome the pressure of check valve spring from the air intensity of safety and shock-absorption air bag cushion of elevator blast pipe loudspeaker ventilation inlet, back down check valve and in the elevator safety air bag cushion, fill into air, air pressure in air bag adds that passenger's feet steps on power and the check valve spring elastic force intensity greater than blast pipe exit skirt air pressure, check valve will seal, air in the elevator safety air bag cushion just can not leak, this moment, gas filed elevator safety air bag cushion just filled up in passenger's underfooting, in order to bumper and absorbing shock when elevator contacts to earth, reduce passenger's damage.

Characteristics of the present utility model are, the reply emergency situation takes place, and the minimizing accident is damaged the passenger.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1, air bag cushion; 2, blast pipe; 3, check valve; 4, valve seat; Check valve spring; 6, spring backing pin; 7, ventilation inlet.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

In the diagram, its shape size is identical with the elevator tank top plate, undersized, be provided with appendix extends outside the elevator on the limit near the inside, be provided with individual event valve in the blast pipe, valve seat, check valve spring, it is horn-like that the ventilation inlet of appendix is back-off, at ordinary times, check valve in the blast pipe seals air inlet pipe under action of the spring, no air safety and shock-absorption air bag cushion of elevator is as same Zhang Putong pad in the air bag cushion, pad is layered on the interior floor of elevator, when abnormal tenesmus appears in elevator, the acceleration/accel of its decline is near the moment of 9.8m/s2, overcome the pressure of check valve spring from the air intensity of safety and shock-absorption air bag cushion of elevator blast pipe loudspeaker ventilation inlet, back down check valve and in the elevator safety air bag cushion, fill into air, air pressure in air bag adds that passenger's feet steps on power and the check valve spring elastic force intensity greater than blast pipe exit skirt air pressure, check valve will seal, air in the elevator safety air bag cushion just can not leak, this moment, gas filed elevator safety air bag cushion just filled up in passenger's underfooting, in order to bumper and absorbing shock when elevator contacts to earth, reduce passenger's damage.

Claims

1. safety and shock-absorption air bag cushion of elevator is characterized in that: shape size, undersized identical with the elevator tank top plate outside the limit near the inside is provided with blast pipe pipe extension elevator, is provided with individual event valve, valve seat, check valve spring in the blast pipe.

2. safety and shock-absorption air bag cushion of elevator according to claim 1 is characterized in that: it is horn-like that the ventilation inlet of blast pipe is back-off.
