Abstract
The invention discloses an adjustable chair leg. The adjustable chair leg consists of an outer leg, an inner leg, a friction sheet, a motor, a trapezoidal gear, a switch, a storage battery and a sliding chute, and is characterized in that the movable inner leg and a control device for adjusting the tightness of the inner leg are arranged in the outer leg. When the switch is pressed and held, the power supply of the motor is switched on through the storage battery, the motor rotates positively to drive the trapezoidal gear to move upwards along the sliding chute, and the friction sheet is driven to move; when the switch is released, the motor is switched off and stops working, at the moment, the inner leg is separated from the friction sheet and can extend and retract freely, and the extension degree of the inner leg is adjusted according a height required to be increased for the outer leg; when the switch is pressed and held after adjustment, the motor is switched on once again, the motor rotates reversely to drive the trapezoidal gear to descend along the sliding chute, and the friction sheet is driven to move in order to fix the inner leg; finally, the switch is released, the motor is switched off, and the inner leg and the outer leg are integrated.
Description
Technical field
The present invention relates to a kind of chair leg height regulating function of seat, is a kind of barbed chair leg concretely.
Background technology
When ground is uneven, the chair leg of seat just can not steadily, make people's seat vacillating and staggering on chair, and the seat of existing market does not have the function that freely independently can extend on leg and regulate chair leg, in use makes troubles therefore to people.
Through retrieval, publication number: CN201624348U utility model patent, patent name: the chair of foldable telescopic, its content also states chair leg can be up and down, but its function existed is overall rise and fall, can not solve the chair leg that differs of needs height because ground injustice causes, meanwhile, its structure is also only that latch is fixed.
Summary of the invention
The object of the present invention is to provide a kind of barbed chair leg, efficiently solving seat leg can the effect of free up-down adjustment.
The present invention realizes with following technical scheme: a kind of barbed chair leg, be made up of outer leg, interior leg, friction plate, motor, trapezoidal gear, switch, battery, chute, it is characterized in that: the control device installing leg and the interior leg degree of tightness of adjustment in an activity in outer leg, described control device fixes one piece of friction plate on the right side of trapezoidal gear, the trapezoidal gear back side is movably arranged in chute, the tooth bar of trapezoidal gear is corresponding with the gear of motor, switch input terminal is connected with battery, and output is connected with motor.Do not put by upper switch, battery electric conduction electromechanical source, motor rotates forward and drives trapezoidal gear, while rising, movable friction plate is also with to move along chute, trip switch, motor power-off also quits work, now, interior leg and friction plate depart from, interior leg retractable, according to the ductility of leg in the height adjustment that outer leg will increase, after mixing up, press switch not put, motor is conducting again, motor reversal drive trapezoidal gear along chute toward be also with while declining movable friction plate move fixing in leg, last trip switch, motor power-off, makes inside and outside leg integral.
The electric energy of described battery is electrically connected supplementary through transformer with room.
Described switch is arranged on outer leg left-external side lower end.
Described motor and battery are arranged on the left inside lower end of outer leg.
Described chute is fixed on the middle-end on the left of outer leg.
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 chair leg and can independently regulate flexible function.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of barbed chair leg of the present invention.
Fig. 2 is that the interior leg of a kind of barbed chair of the present invention leg extends schematic diagram.
1. outer legs in figure, leg 2., 3. friction plate, 4. motor, 5. trapezoidal gear, 6. switch, 7. battery, 8. chute.
Detailed description of the invention
A kind of barbed chair leg of the present invention, structure comprises: outer leg 1, interior leg 2, friction plate 3, motor 4, trapezoidal gear 5, switch 6, battery 7, chute 8.
In FIG, the control device of leg 2 and interior leg 2 degree of tightness of adjustment in an activity is installed in outer leg 1, described control device fixes one piece of friction plate 3 on the right side of trapezoidal gear 5, trapezoidal gear 5 back side is movably arranged in chute 8, the tooth bar of trapezoidal gear 5 is corresponding with the gear of motor 4, switch 6 input is connected with battery 7, and output is connected with motor 4.
Friction plate 3 tightens together with interior leg 2.
In fig. 2, each assembly is installed consistent with Fig. 1 with position, but interior leg 2 is to downward-extension, the ductility of adjustable interior leg 2.
Friction plate 3 separates with interior leg 2, to make interior leg 2 movable telescopic be adjusted to Len req.
