The two lifting units can control the seat to descend to the position of the septum relative to the ground surface, the seat can be lifted above the ground surface to be used by people for rest, and the seat can be lifted according to requirements, so that the seat can descend when a large space is needed in a bus station, and a larger space is provided for people in the bus station.

Drawings

FIG. 1 is a schematic structural view of the present invention;

figure 2 is a schematic cross-sectional view of the seat and base of the present invention in cooperation.

In the figure: 1. the device comprises an empty space, 2, a beam, 3, a stand column, 4, a hydraulic cylinder, 5, a V-shaped rotating arm, 6, first supports, 7, second supports, 8, a base, 9, first limit stops, 10, second limit stops, 11 and a chair seat.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1 and 2, a lifting seat for a platform comprises a seat 11 with a rectangular cross section and an accommodating space 1 arranged below the ground surface, wherein an opening with the same size as the seat 11 is arranged at the upper end of the accommodating space 1, a bracket is arranged at the bottom of the accommodating space 1, the bracket comprises a beam 2 and a column 3, the beam 2 is horizontally and fixedly arranged in the accommodating space 1 through the column 3, a lifting unit is symmetrically arranged at the left side and the right side of the beam 2 respectively, the lifting unit comprises a hydraulic cylinder 4, a V-shaped rotating arm 5, a support seat 6 and a support seat II 7, the support seat I6 is obliquely arranged at the end part of the beam 2 with a low outside and a high inside, the support seat II 7 is obliquely arranged at the lower part of the beam 2 with a low outside and a high inside, the lower end of the support seat I6 is higher than the lower end of the support seat II 7, the cylinder seat of the hydraulic cylinder 4 is hinged, the inflection point of the V-shaped rotating arm 5 is hinged with the lower end of the first support 6, the head of a piston rod of the hydraulic cylinder 4 is hinged with the lower end of the V-shaped rotating arm 5, and the upper end of the V-shaped rotating arm 5 is hinged with a base 8 which is slidably arranged at the lower part of the chair surface 11; the base 8 is in sliding fit with the lower part of the chair seat 11; the middle part of the lower surface of the chair surface 11 is provided with a sliding chute with a dovetail-shaped section along the length direction, and the upper end of the base 8 is provided with a guide rail with a dovetail-shaped section matched with the sliding chute; two ends of the chair surface 11 are symmetrically provided with first limit stops 9 for limiting the maximum angle of the V-shaped rotating arm 5, and the sliding groove is positioned between the first limit stops 9. Can control the seat through two elevating unit and descend to the position with ground surface phase platform, can also make it rise to the above-mentioned confession people of earth's surface and have a rest, this seat can go up and down as required to make the seat descend when needing great space in the bus stop, thereby provide bigger space for the people in the bus stop.

In order to control the maximum rising height of the seat 11, a second limit stop 10 for limiting the inward maximum sliding position of the base 8 is arranged at the center of the lower part of the seat 11, and the sum of the thickness of the second limit stop 10 and the thickness of the seat 11 is equal to the distance from the upper end of the support to the ground surface. The second limit stop 10 has a length long enough to ensure that both ends thereof respectively limit the bases 8 on both sides thereof.

When the device is used, the hydraulic cylinders 4 of the two lifting units move synchronously, when the device is used in rainy days or snowy days, the two hydraulic cylinders 4 are controlled to retract synchronously, the seat 11 is driven to move downwards by the V-shaped rotating arm 5, when the base 8 slides outwards to the position of the first limit stop 9, the upper surface of the seat 11 is lowered to be flush with the ground surface, and meanwhile, the second limit stop 10 of the seat 11 is abutted against the upper end of the support, so that the seat 11 can still have good bearing strength after being lowered; when the seat is required to be normally used, piston rods of the two hydraulic cylinders 4 are simultaneously controlled to extend outwards, the base 8 is driven to slide inwards through the V-shaped rotating arm 5, when the base 8 abuts against the position of the second limit stop 10, the seat surface 11 rises to the highest height above the ground surface, and the seat can be normally used.
