Including four described secondary bed course portions being respectively at immediately below each lower tie-beam, secondary bed course described in adjacent two
The angle in portion is formed with the accommodating space of the accommodating outer barrel.
After adopting the above technical scheme, protective car buffer unit in elevator of the invention, in actually used process
In, the side wall of elevator bottom is formed with the hook and slot of the accommodating hook portion of correspondence, and bumper bracket can fall the car in elevator shaft bottom portion under
Enter row buffering, car is come to a complete stop, protective buffering device can enter row buffering to objects such as the people that is fallen in elevator, to the people for falling
Protected Deng object.Specifically when car will down fall elevator shaft bottom portion, lower extension is supported plate and can be supported in shank portion
Top, with car continuation fall, shank portion drive hook portion overcome the torsion of torsion spring overturn gradually downward where
Inner cylinder, makes crotch deviate from the hook and slot on elevator, and after plate is supported in extension to be supported with hook portion completely, buffer switch is to open,
Inner cylinder carries out elastic buffer support using the support spring in outer barrel and by crotch to car, car is gradually come to a complete stop；When right
Staff that elevator is repaired or passenger etc. fall because accidentally elevator when, crotch snaps in the hook of elevator using hook portion
Blocked in groove, shank portion carries out upward support and card handle is stuck in inner cylinder inner side and carries out spacing, is temporarily lost with elastomeric support column
Elasticity and powerful support is carried out to upper cushion, elastic web layer, spongy layer and elastic air cushion layer first step buffering is carried out to human body,
In first step buffering course, the suspension parts for containing frame is pressed downwards using each hook part to each first gear, the first tooth
Wheel drives the first tooth bar using the first adapter sleeve, and vertically guide post compresses downwards the first stage clip, and the first tooth bar is oriented to by first
Groove is engaged the vertical guide planes slide downward along first with vertical guide convex rail on first, using each first stage clip to human body
Auxiliary buffering is carried out, groove and the first oblique guide convex rail are oriented to by first when the first tooth bar slips over vertical guide planes on first
It is engaged when being slided gradually downward along the first oblique spigot surface, the first oblique spigot surface is gradually to the first tooth bar to its second end side
To promotion, each first gear of the first rack drives is rotated, and hook part is moved closer to the first sector notch, when the first tooth bar is slided
The first oblique spigot surface is crossed to be engaged along first time vertical guide planes with vertical guide convex rail under first by the first guiding groove
During slide downward, hook part is corresponding with the first sector notch and is come off from first gear and hangs over corresponding second gear
On, being come off from first gear, it is excessive to be prevented effectively from the initial impulsive force of human body, and bounce is excessive cause human body to rebound after
Additional injury；Next enter second step buffering, contain frame suspension parts using each hook part to each second gear to
Lower pressure, second gear drives the second tooth bar using the second adapter sleeve, and vertically guide post compresses downwards the second stage clip, the second tooth
Bar is engaged the vertical guide planes slide downward along second by the second guiding groove with vertical guide convex rail on second, using each
Second stage clip carries out second auxiliary buffering to human body, relies on the second guiding recessed when the second tooth bar slips over vertical guide planes on second
Groove is engaged when being slided gradually downward along the second oblique spigot surface with the second oblique guide convex rail, and the second oblique spigot surface is gradually right
Second tooth bar is promoted to its 4th extreme direction, and each second gear of the second rack drives is rotated, hook part and the second sector notch
Move closer to, match when the first tooth bar slips over vertical guide convex rail under the second oblique spigot surface is oriented to groove and second by second
Close along second time vertical guide planes slide downward when, from second gear come off corresponding with the second sector notch of hook part and
Making entirely to go up fall on bottom breaker under cushion, and being come off from second gear can further avoid the impulsive force of human body excessive,
And the excessive additional injury caused after human body bounce-back of bounce, the 3rd step buffering is carried out, herein in the 3rd step buffering, elastic air cushion
The lower air cushion portion of layer carries out the flexible pressure of uniform comprehensive engagement, main bed course portion elastic deformation to the main bed course portion of elastic water subfill
And enter row buffering to upper cushion and human body, while the water in main bed course portion can progress into secondary bed course portion through permeable hole
In, permeable hole can delay current to enter to strengthen the elastic and extension elastic release time of elastic water subfill in secondary bed course portion, with
The effect that effective buffering is carried out to upper cushion and human body is reached, after impact terminates, can be by saturating into the water in secondary bed course portion
Water hole is back in main bed course portion again.By after the different buffer stage of three steps, the impulsive force of human body is effectively buffered, human body
Finally steadily rest on elastic web layer, it is ensured that personnel's personal safety.Compared with prior art, protection in elevator of the invention
Property car buffer unit, it can carry out effectively stable buffering to the personnel in elevator that fall, it is ensured that personal safety, practical
Property is strong.
