Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Embodiment one
Fig. 1~2 are referred to, in the utility model embodiment, a kind of anti-crouching bottom safeguard construction of lift car, including：It is flexible
Bar 4, support plate 5, buffer structure and anti-bounce-back structure, the expansion link 4 include the first bar segment 41 and the second bar segment 42, described the
One bar segment 41 is hinged on pin bearing 2 by the first bearing pin 31, and expansion link 4 and pin bearing 2 have four groups, four 2 points of pin bearings
Four vertex positions of the bottom of car 1 are not weldingly fixed on, and second bar segment 42 is arranged in the first bar segment 41, can be first
Slided in bar segment 41；The support plate 5 is cylinder disk body, and four the second symmetrical bearing pins 32, second are installed on its circumference
The bottom of bar segment 42 is connected on four the second bearing pins 32；The buffer structure includes sleeve 11 and stage clip 10, the set
Cylinder 11 is weldingly fixed on the bottom surface center position of car 1, and the stage clip 10 is arranged in sleeve 11, when car 1 drops, works as support
After disk 5 is bottomed out, car 1 continues to move down, the contraction in length of expansion link 4, and stage clip 10 is compressed, and elastic force is produced, by the kinetic energy of car 1
The elastic potential energy of stage clip 10 is converted to, so that the speed of car 1 is gradually reduced；The anti-bounce-back structure includes hooking pawl 8 and sets
The briar tooth 9 on the excircle of sleeve 11 is put, hook pawl 8 bottom is hinged in support plate 5, when car 1 falls, under sleeve 11
Move, move to hook 8 position of pawl when, hook pawl 8 briar tooth 9 is caught on, when car 1 decelerate to 0 and under the elastic force of stage clip 10 to
During upper resilience, after hook pawl 8 catches on briar tooth 9, car 1 forms overall structure with stage clip 10 and support plate 5, can so make car
1 quickly settles out, and otherwise, in the presence of stage clip 10, energy is by the kinetic energy of car 1, gravitional force and stage clip 10
Elastic potential energy between convert repeatedly, car 1 needs the longer time just to come to a complete stop, and causes passenger in car 1 to stand firm, and compares
It is dangerous.
The anti-bounce-back structure has four groups, is evenly arranged along the circumferencial direction of sleeve 11 respectively.
It is described to hook installation torsionspring 7 on the jointed shaft that be connected with support plate 5 of pawl 8, the offer of torsionspring 7 make hook pawl 8 to
The elastic force of the center of circle direction movement tendency of support plate 5.
The gluing floor height resilient rubbber cushion 6 in the bottom of the support plate 5, with reduce the vibration produced when support plate 5 is bottomed out and
Noise.
