Abstract

A kind of control method of barbed chair lower limb, do not put by upper switch, accumulator electric conduction electromechanical source, motor rotates forward and drives trapezoidal gear, along chute toward rise while also band movable friction plate move, trip switch, motor power-off also quits work, now, interior lower limb departs from friction plate, interior lower limb retractable, according to the ductility of lower limb in the altitude mixture control that outer lower limb is to be increased, after mixing up, press switch not put, motor turns on again, motor reversal drive trapezoidal gear along chute toward decline while also band movable friction plate move fix in lower limb, last trip switch, motor power-off, make inside and outside lower limb integral.

Description

A kind of control method of barbed chair lower limb

Technical field

The present invention relates to the chair lower limb height regulating function of a kind of seat, be concretely a kind of barbed chair lower limb.

Background technology

When ground injustice, the chair lower limb of seat will be unstable, makes people's seat vacillating and staggering on chair, and existing market Seat is the function not having and can the most independently extending regulation chair lower limb on lower limb, in use makes troubles therefore to people.

Through retrieval, publication number: CN201624348U utility model patent, patent name: the chair of foldable telescopic, in it Also statement chair lower limb can be up and down for appearance, but its function existed is overall rise and fall, it is impossible to solves because of ground not The chair lower limb that the flat needs height caused differs, meanwhile, its structure is also only that latch is fixed.

Summary of the invention

It is an object of the invention to provide a kind of barbed chair lower limb, efficiently solving seat leg can the work of free up-down adjustment With.

The present invention realizes with following technical scheme: a kind of barbed chair lower limb, by outer lower limb, interior lower limb, friction plate, motor, Trapezoidal gear, switch, accumulator, chute form, and it is characterized in that: install lower limb and the interior lower limb degree of tightness of regulation in an activity in outer lower limb Control device, described control device is to fix one piece of friction plate on the right side of trapezoidal gear, the activity of the trapezoidal gear back side pacify Being contained in chute, the tooth bar of trapezoidal gear is corresponding with the gear of motor, and switch input terminal is connected with accumulator, outfan and electricity Machine connects.Not putting by upper switch, accumulator electric conduction electromechanical source, motor rotates forward and drives trapezoidal gear, along chute toward rising The most also band movable friction plate moves, trip switch, and motor power-off also quits work, and now, interior lower limb departs from friction plate, and interior lower limb can Freely stretching, according to the ductility of lower limb in the altitude mixture control that outer lower limb is to be increased, after mixing up, press switch and do not put, motor is again Conducting, motor reversal drive trapezoidal gear along chute toward while declining also band movable friction plate move fixing in lower limb, finally loose Switch, motor power-off, make inside and outside lower limb integral.

The electric energy of described accumulator electrically connects supplementary through transformator with room.

Described switch is arranged on outer lower limb left-external side lower end.

Described motor and accumulator are arranged on the left inside lower end of outer lower limb.

Described chute be fixed on the left of outer lower limb in middle-end.

Described chute length is equal with trapezoidal gear length.

Described chute setting angle is 35 degree of angles.

Described trapezoidal gear setting angle is 35 degree of angles.

Described switch is two-way switch.

Beneficial effect: have and achieve the function that chair lower limb energy independent regulation is flexible.

Accompanying drawing explanation

Fig. 1 is the structure chart of a kind of barbed chair lower limb.

Fig. 2 is that the interior lower limb of a kind of barbed chair lower limb extends schematic diagram.

1. outer lower limb in figure, 2. in lower limb, 3. friction plate, 4. motor, the most trapezoidal gear, 6. switch, 7. accumulator, 8. chute.

Detailed description of the invention

One barbed chair lower limb of the present invention, structure includes: outer lower limb 1, interior lower limb 2, friction plate 3, motor 4, trapezoidal gear 5, open Pass 6, accumulator 7, chute 8.

In FIG, lower limb 2 and the control device of interior lower limb 2 degree of tightness of regulation, described control in an activity is installed in outer lower limb 1 Device processed is to fix one piece of friction plate 3 on the right side of trapezoidal gear 5, and trapezoidal gear 5 back side is movably arranged in chute 8, trapezoidal The tooth bar of gear 5 is corresponding with the gear of motor 4, switchs 6 inputs and is connected with accumulator 7, and outfan is connected with motor 4.

Friction plate 3 tightens together with interior lower limb 2.

In fig. 2, each assembly is installed consistent with Fig. 1 with position, but interior lower limb 2 downwardly extends, the extension of lower limb 2 in scalable Degree.

Friction plate 3 separates with interior lower limb 2, in order to make interior lower limb 2 movable telescopic regulate to Len req.

Claims

1. a control method for barbed chair lower limb, is characterized in that: do not put by upper switch, accumulator electric conduction electromechanical source, motor Rotate forward drive trapezoidal gear, along chute toward rising while also band movable friction plate move, trip switch, motor power-off also stops Work, now, interior lower limb and friction plate depart from, interior lower limb retractable, according to the prolonging of lower limb in the altitude mixture control that outer lower limb is to be increased Degree of stretching, after mixing up, presses switch and does not puts, and motor turns on again, and motor reversal drives trapezoidal gear same toward decline along chute Time also band movable friction plate move fixing in lower limb, last trip switch, motor power-off, make inside and outside lower limb integral.
