Abstract
The present invention relates to a lifting and falling chair whose seat height can be regulated. It includes a supporting frame, a back, a seat and a seat supporting frame. Said back is fixed on the supporting frame, and its seat is fixed on the seat supporting frame. Said invention also provides the concrete structure of back and seat supporting frame, and also provides the concrete method for regulating seat height.
Description
Technical field
The present invention relates to the adjustable for height seat of a kind of seat, especially regulate the chair lift of seat by rotary handle.
Background technology
Present known chair lift exists whole assembly relation complexity, problems such as component structural complexity, cost height.Though also some scheme is simple in structure, adjust to get up to waste time and energy, be not easy to use, need by pedal the seat position to be adjusted before use as patent 88204321.8; Patent 00257527.2 need change the corner that is produced by rotation between the upper and lower swivel plate and reach studdle under the booster action of pin leg, makes it rotate corresponding angle with respect to nut sleeve, thus execution.In addition, existing chair lift, its elevating mechanism all place seat below, and seat must be with the common lifting of backrest, so need the load weight of above all parts of seat of elevating mechanism, make that the elevating mechanism load-carrying is bigger, as patent 200320106339.7 etc.
Summary of the invention
Need the problem of common lifting in order to solve seat and backrest in the existing chair lift structure, to reduce the load of elevating mechanism, at utmost utilize useful work, improve lifting efficient, the invention provides a kind of chair lift of adjustable chair face height, simple in structure, easy to operate, can not only regulate the seat height easily, and being suitable for processing and assembling, the parts that adopt mostly are lower-cost general part greatly, thereby have reduced production cost.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of chair lift of adjustable chair face height, comprise support, backrest, seat and seat support, described backrest is fixed on the support, described seat is installed on the described seat support, it is characterized in that described backrest has the tooth bar shape draw-in groove of two vertical parallel, the one side is a rectangular teeth, and opposite side is communicated with; The rectangular teeth inserting of the tooth bar shape draw-in groove of square pole that described seat support is two horizontal parallel and described backrest.
Revolve about two square poles of above-mentioned seat support have respectively and revolve screw thread about the two ends of a screw and a screw rod and revolve and join the fixedly connected rotary handle of an end of described screw rod.
Above-mentioned seat has four chutes, passing described chute by four screws is installed in seat on two square poles of seat support, described screw and two square poles of described seat support are fixed, and together move with seat support square pole in described chute.
Two above-mentioned draw-in groove inboards are rectangular teeth, and the outside is communicated with; Perhaps described two draw-in grooves are inboard to be communicated with, and the outside is a rectangular teeth.
There is level rectangle crotch to the inside the end of two square poles of above-mentioned seat support after inserting backrest.
The invention has the beneficial effects as follows, reduced the load that elevating mechanism bears, thereby improved mechanical efficiency.It is simple in structure, is easy to processing, can regulate arbitrarily the seat height by rotary handle, uses very conveniently, can be widely used in the chair lift mechanism in various places such as family, office, amusement.
Description of drawings
Below in conjunction with drawings and Examples type of the present invention is described further.
Fig. 1 is the structure chart of one embodiment of the invention.
Fig. 2 is the seat installation diagram of Fig. 1 example.
Fig. 3 is the upward view of the seat of Fig. 1 example.
The specific embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the present invention:
As shown in Figure 1, the chair lift of this adjustable chair face height is made up of support 1, backrest 2, seat 4, seat support 6, screw 7, rotary handle 8 and screw rod 9.Wherein, backrest 2 is fixedly mounted on the support 1, the tooth bar shape of 2 two vertical parallel of backrest has draw-in groove 3, draw-in groove 3 inboards are rectangular teeth, the outside is communicated with, and seat support 6 is the square pole of two horizontal parallel, revolves screwed hole about having on two square poles, connect with screw rod 9, and snap in respectively in the rectangular teeth of draw-in groove 3.Seat 4 has four chutes 5, seat 4 is fixed on two square poles of seat support 6 with four screws 7, and screw 7 can move with seat support 6 in seat chute 5, and screw rod 9 one ends are equipped with rotary handle 8.When rotating rotary handle 8, because screw rod 9 two ends hand of spirals are opposite, seat support 6 all will move laterally, the screw 7 that is fixed thereon simultaneously together slides in seat chute 5 laterally, so support 6 separates to both sides with respect to seat 4, and from the inboard rectangular teeth part of draw-in groove 3, break away from, enter outside connected component, and can in connectivity slot, slide up and down, thereby can regulate the seat height arbitrarily.After finishing adjusting, reverse rotation handle 8, then 6 liang of square poles of both sides seat support all move to the inside, and screw 7 is shifted to the most inboard and seat 4 is locked of chute 5 simultaneously, and it is locked with the seat position that 6 liang of square poles of seat support enter the rectangular teeth position of draw-in groove 3.
In seat 4 installations diagram shown in Figure 2, screw rod 9 two ends process the screw thread that revolves about a section respectively, and wherein an end is connected with rotary handle 8.Seat support 6 liang of square poles in both sides also have left and right sides screwed hole, and connect by screw rod 9.Seat 4 has four chutes 5, by four screws 7 seat 4 is fixed on seat support 6 square poles, and screw 7 plays the fixedly effect of seat and slide-and-guide.
