Description

A kind of elevator safe buffering seat

Technical field

This utility model relates to seat, particularly a kind of elevator safe buffering seat.

Background technology

Elevator is divided into two big classes, staircase and lift substantially, lift be mainly used in megastore, building in the morning, residential building, Hospital, school etc., and because the used during elevator falling accident that lift is long neglected and in disrepair or other reasons causes also has a lot, present market The upper buffer unit for elevator cushion is essentially all employing cushion pad or spring plays a cushioning effect, but with electricity The impulsive force of ladder high-speed falling impacts on these cushion pads or spring, and elevator can be upspring, easily to elevator because of elastic Interior passenger causes secondary injury, usually can put a seat for passenger, especially old man, child, anemia of pregnant woman in existing elevator Etc. taking rest, it is used for having a rest when how this seat can be transformed into a normal traveling, can fill again during accident of falling When safety protection equipment is people's concerns.

Utility model content

For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of elevator and uses Safe buffering seat, the problem that can effectively solve to use elevator seat to carry out used during elevator falling security protection.

The technical scheme that this utility model solves is, a kind of elevator safety buffer armchair, including support be contained on support Seat, support has and is symmetricly set on 2 of seat both sides, and each support all includes two supporting legs and is arranged on two supporting leg tops The crossbeam linked together by two supporting legs, seat is mounted on below crossbeam through the buffer spring being contained in crossbeam bottom straight down Two stands between, be respectively provided with gag lever post outside seat two, gag lever post is placed in the cushioning rail of support both sides, constitute limit Position bar, along the upper and lower slide construction of cushioning rail, is provided with in the cushioning rail in the glide direction of gag lever post and multiple makes limit Position bar can pass downwardly through and cannot upwardly through unidirectional opening-closing structure, constitute power buffering transferring structure.

This utility model novel structure is unique, and advantages of simple easily produces, low cost, is available for passenger and is seated time properly functioning Having a rest, when there is used during elevator falling accident, passenger only need to be sitting on seat i.e. available effective buffering, it is ensured that life security, It it is the innovation on elevator accident preventer.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Being given by Fig. 1-5, this utility model includes support and the seat being contained on support, and support is symmetricly set on seat 2 of 3 both sides, each support all includes two supporting leg 1b and is arranged on the horizontal stroke that two supporting legs are linked together by two supporting leg tops Beam 1a, seat 3 between the two stands that the buffer spring 2 being contained in crossbeam bottom straight down is mounted on below crossbeam, seat 3 liang Outside is respectively provided with gag lever post 4, and gag lever post 4 is placed in the cushioning rail 5 of support both sides, constitutes gag lever post along cushioning rail 5 Upper and lower slide construction, is provided with in the cushioning rail in the glide direction of gag lever post and multiple enables gag lever post to lead to downwards Cross and cannot upwardly through unidirectional opening-closing structure, constitute power buffering transferring structure.

For ensureing using effect, described cushioning rail 5 includes housing 51, has for limit before and after housing 51 in both ends of the surface The sliding stroke passage 56 that position bar slides through, before and after can emptying housing as shown in Figure 4,5, both ends of the surface are as sliding for gag lever post The dynamic sliding stroke passage passed through, unidirectional opening-closing structure is distributed in housing the most successively；

Described unidirectional opening-closing structure includes loose-leaf 55 and the horizontal level limit being arranged in the inner walls above loose-leaf Position block 53, loose-leaf is contained in inner walls through rotating shaft 52, constitutes upset structure, is provided with and makes loose-leaf between loose-leaf and inner walls Can recover the back-moving spring 54 of horizontal level after upset, after seat stress, stretch buffer spring, gag lever post is downward along with seat Mobile, when gag lever post contact loose-leaf, back down loose-leaf and pass through to continue to move down, after gag lever post passes through, loose-leaf is at back-moving spring Recovering horizontal level under elastic force effect, gag lever post is with seat continuous slide, until the kinetic energy of seat stress is fully converted to buffering The elastic potential energy of spring, seat and gag lever post all stop moving downward, and now under the elastic force effect of buffer spring, seat starts Move up, drive gag lever post to move up simultaneously, when gag lever post moves to a his nearest unidirectional opening-closing structure, lived Page stops, power is delivered to cushioning rail；

Bottom buffer spring 57 it is provided with on the housing of described sliding stroke channel bottom；

Described gag lever post 4 is connected to the both sides of seat through connecting rod 6, and connecting rod and cushioning rail stagger setting；

Described elevator safety buffer armchair is arranged in elevator, and cushioning rail is fixed together with elevator, can will buffer The stress of track passes to elevator.

When this utility model uses, when there is used during elevator falling, when landing, elevator stops suddenly, and people's inertia is downward, to seat Applying a downward power, after seat stress, stretch buffer spring, gag lever post moves down along with seat, when gag lever post contacts During loose-leaf, backing down loose-leaf and pass through to continue to move down, after gag lever post passes through, loose-leaf recovers level under back-moving spring elastic force effect Position, with seat, gag lever post continues to move down until that the kinetic energy of seat stress is fully converted to the elastic potential energy of buffer spring, Seat and gag lever post all stop moving downward, and now under the elastic force effect of buffer spring, seat begins to move up, and carries simultaneously Dynamic gag lever post moves up, and when gag lever post moves to a his nearest unidirectional opening-closing structure, is stopped by loose-leaf, and power is passed To cushioning rail；When actually used, the spring of different coefficient of elasticity is selected to be used as buffer spring according to different buildings height, with Adapt to differing heights floor elevator, make the maximal tensility of spring in the range of cushioning rail, compared with prior art, this reality Unique by new structure novelty, advantages of simple, easily produce, low cost, be available for passenger time properly functioning and be seated rests, generation elevator During falling accident, passenger only need to be sitting on seat i.e. available effective buffering, and be provided with multiple unidirectional opening-closing structure with Adapt to different floors, injury is reduced to minimum, it is ensured that life security, be the innovation on elevator accident preventer, have Good Social and economic benef@.
