Description
Technical field
The invention belongs to household furniture field, be specifically related to a kind of chair lift structure technology.
Background technology
The chair lift of prior art generally adopts and arrange hydraulic cylinder to drive the lifting of seat between base and seat, the deficiency of such chair lift be hydraulic cylinder in use for some time sealing to decline even leakage, its guiding mechanism also easily damages, and result of use is undesirable.
Summary of the invention
The object of the invention is: the deficiency existed for prior art, provide a kind of rational in infrastructure, height continuously adjustabe saves and the chair lift of long service life.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of chair lift, include base and be positioned at the seat above base, be fixedly connected with lifting overcoat above base, under-seat is fixedly connected with the elevating lever be slidably connected with described lifting overcoat; Described elevating lever bottom is fixedly connected with lifting guide nut, and base is positioned at lifting overcoat and is connected with hollow lifting screw by bearing, lifting screw is connected by screw-driven with lifting guide nut; The top of described elevating lever is provided with an adjustment seat, adjustment seat is connected with a driving shaft in the horizontal direction and a lifting drive rod vertically by bearing, driving shaft is fixedly connected with one and drives helical gear and a regulating handle, lifting drive rod upper end be fixedly connected with one with the driven helical gear of described driving helical gear engaged transmission, described lifting drive rod bottom sliding plug coaxial with lifting screw.
Preferably: described base is H-shaped, the base connecting plate that comprises the parallel feet in both sides and be connected with two feet middle point vertical; Described lifting overcoat is fixedly connected on top in the middle part of connecting plate, is connected to reinforced pole between two described feet rear portions and lifting overcoat top.The base of H-shaped has saved material, and it is more firm that reinforced pole makes lifting overcoat be connected with base.
Preferably: the adjustment seat upper end of described elevating lever is connected with one piece of connecting plate, 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 by screw on connecting plate.The parts in adjustment seat can be assembled so easily before seat is installed.
Compared with prior art, the invention has the beneficial effects as follows: this chair lift can adjust seat to desired height position, height of seat continuously adjustabe rapidly by rotating regulating handle, and chair lift overall structure is firm, long service life.

Detailed description of the invention
With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.
According to Fig. 1 and Fig. 2, a kind of chair lift described in the present embodiment, include base 1 and be positioned at the seat 4 above base 1, be fixedly connected with lifting overcoat 2 above base 1, below seat 4, be fixedly connected with the elevating lever 3 be slidably connected with described lifting overcoat 2; Described elevating lever 3 bottom is fixedly connected with lifting guide nut 32, and base 1 is positioned at lifting overcoat 2 and is connected with hollow lifting screw 7 by bearing, lifting screw 7 is connected by screw-driven with lifting guide nut 32; The top of described elevating lever 3 is provided with an adjustment seat 31, adjustment seat 31 is connected with a driving shaft 5 in the horizontal direction and a lifting drive rod 6 vertically by bearing, driving shaft 5 is fixedly connected with one and drives helical gear 51 and a regulating handle 52, lifting drive rod 6 upper end be fixedly connected with one with the driven helical gear 61 of described driving helical gear 51 engaged transmission, described lifting drive rod 6 bottom sliding plug coaxial with lifting screw 7.
Described base 1 is H-shaped, the connecting plate 12 that base comprises the parallel feet in both sides 11 and is connected with two feet 11 middle point vertical; Described lifting overcoat 2 is fixedly connected on top in the middle part of connecting plate 12, is connected to reinforced pole 8 between two described feet 11 rear portions and lifting overcoat 2 top.Described connecting plate 12 and feet 11 are welded and fixed, and lifting overcoat 2 is welded and fixed with feet 11, reinforced pole 8 two ends respectively with feet 11, be elevated overcoat 2 and be welded and fixed.
Adjustment seat 31 upper end of described elevating lever 3 is connected with one piece of connecting plate 33, and described seat 4 lower end edge seat 4 left and right directions is fixedly connected with the seat pole 41 of two U-shapeds, and seat pole 41 is connected by screw on connecting plate 33.
As shown in Figure 1, when rotating counterclockwise regulating handle 52, driving shaft 5 drives and drives helical gear to rotate counterclockwise, helical gear 51 is driven to drive driven helical gear 61 to rotate clockwise, driven helical gear 61 drives lifting drive rod 6 to rotate clockwise again, lifting screw 7 clockwise coaxial rotation thereupon, and then lifting guide nut 32 moves up along lifting screw 7, thus drive elevating lever 3 to move up finally to make seat 4 increase; In like manner rotate clockwise regulating handle 52 regulating chair 4 to decline.
