Description
Technical field
The invention belongs to the household furniture field, be specifically related to a kind of chair lift structure technology.
Background technology
The chair lift of prior art generally adopts the lifting that hydraulic cylinder drives seat is set between base and seat, the deficiency of such chair lift be hydraulic cylinder in use for some time sealing can descend even leakage, its guiding mechanism also damages easily, and result of use is undesirable.
Summary of the invention
The objective of the invention is: the deficiency at prior art exists, provide a kind of rational in infrastructure, can regulate highly continuously and the chair lift of long service life.
For realizing the present invention's purpose, be achieved by the following technical solutions: a kind of chair lift, the seat that includes base and be positioned at the base top, the base upper fixed is connected with the lifting overcoat, and under-seat is fixedly connected with the elevating lever that is slidingly connected with described lifting overcoat; Described elevating lever bottom is fixedly connected with the lifting guide nut, is positioned at the lifting overcoat on the base and is connected with hollow lifting screw by bearing, and lifting screw and lifting guide nut are in transmission connection by screw thread; The top of described elevating lever is provided with an adjustment seat, be connected with driving shaft and a lifting drive rod vertically of an along continuous straight runs on the adjustment seat by bearing, be fixedly connected with one on the driving shaft and drive helical gear and a regulating handle, lifting drive rod upper end is fixedly connected with a driven helical gear with described driving helical gear engaged transmission, described lifting drive rod bottom and the coaxial sliding plug of lifting screw.
As preferred version: described base is H shape, and base comprises feet that both sides are parallel and the connecting plate that is connected with two feet middle point vertical; Described lifting overcoat is fixedly connected on top, connecting plate middle part, is connected with reinforced pole respectively between described two feet rear portions and the lifting overcoat top.The base of H shape has been saved material, and it is more firm that reinforced pole makes the lifting overcoat be connected with base.
As preferred version: the adjustment seat upper end of described elevating lever is connected with a connecting plate, and described seat lower end edge seat left and right directions is fixedly connected with the seat pole of two U-shapeds, and seat pole is connected on the connecting plate by screw.Before being installed, can assemble by seat the parts in the adjustment seat so easily.
Compared with prior art, the invention has the beneficial effects as follows: this chair lift can be adjusted seat to the desired height position apace by rotating regulating handle, and height of seat is adjustable continuously, and the chair lift overall structure is firm, long service life.

The specific embodiment
With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.
According to illustrated in figures 1 and 2, the described a kind of chair lift of present embodiment, the seat 4 that includes base 1 and be positioned at base 1 top, base 1 upper fixed is connected with lifting overcoat 2, and seat 4 belows are fixedly connected with the elevating lever 3 that is slidingly connected with described lifting overcoat 2; Described elevating lever 3 bottoms are fixedly connected with lifting guide nut 32, are positioned at lifting overcoat 2 on the base 1 and are connected with hollow lifting screw 7 by bearing, and lifting screw 7 and lifting guide nut 32 are in transmission connection by screw thread; The top of described elevating lever 3 is provided with an adjustment seat 31, be connected with driving shaft 5 and a lifting drive rod 6 vertically of an along continuous straight runs on the adjustment seat 31 by bearing, be fixedly connected with one on the driving shaft 5 and drive helical gear 51 and a regulating handle 52, lifting drive rod 6 upper ends are fixedly connected with a driven helical gear 61 with described driving helical gear 51 engaged transmission, described lifting drive rod 6 bottoms and lifting screw 7 coaxial sliding plugs.
Described base 1 is H shape, and base comprises parallel feet in both sides 11 and the connecting plate 12 that is connected with two feets, 11 middle point vertical; Described lifting overcoat 2 is fixedly connected on top, connecting plate 12 middle parts, is connected with reinforced pole 8 respectively between described two feet 11 rear portions and lifting overcoat 2 tops.Described connecting plate 12 is fixed with feet 11 welding, and lifting overcoat 2 is fixing with feet 12 welding, and reinforced pole 8 two ends are fixed with feet 12,2 welding of lifting overcoat respectively.
As shown in Figure 1, when rotating counterclockwise regulating handle 52, driving shaft 5 drives the driving helical gear and rotates counterclockwise, driving the driven helical gear 61 of helical gear 51 drivings clockwise rotates, driven helical gear 61 drives lifting drive rod 6 again and clockwise rotates, lifting screw 7 is clockwise coaxial rotation thereupon, and then lifting guide nut 32 moves up along lifting screw 7, moves up seat 4 is risen thereby drive elevating lever 3; In like manner clockwise rotating regulating handle 52 adjustable bed rearrangement chairs 4 descends.
