Abstract

The invention discloses an electric lifting chair leg. The electric lifting chair leg comprises an outer leg, an inner leg, a power wire, a motor, a through hole and a switch and is characterized in that the inner leg is mounted in the outer leg; a row of row teeth are arranged at the middle end of the left side of the inner leg; the motor is mounted on the inner left side of the outer leg; a through hole is formed in the lower end of the outer leg; a motor gear is combined with the row teeth of the inner leg; the input end of the switch is connected with the power wire; the output end of the switch is connected with the motor; a power wire plug extends out by virtue of the through hole; a rubber peel is pasted on the right inner side of the outer leg. The power wire is connected with a room power supply and electrified; a green switch is pressed all the time, a power supply of the motor is switched on and the motor rotates positively and drives the row teeth to extend the inner leg downwards; then the switch is loosened and the motor stops working; when the inner leg needs to be adjusted inwards, a red switch is pressed, the motor is switched on, and then the motor rotates reversely and drives the row teeth to move the inner leg upwards; when the inner leg is parallel to the outer leg, the red switch is loosened and the motor is switched off. The electric lifting chair leg has the function of automatically and independently adjusting the height of the chair leg according to unevenness of the ground so as to ensure that each chair leg is in full contact with the ground.

Description

A kind of electric lifting chair leg

Technical field

The present invention relates to a kind of seat, is a kind of electric lifting 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 electric lifting chair leg, efficiently solve seat leg and independently regulate upper and lower function.

The present invention realizes with following technical scheme: a kind of electric lifting chair leg, be made up of outer leg, interior leg, power line, motor, through hole, switch, it is characterized in that: leg in installing in outer leg, on the left of interior leg, middle-end is provided with several rows of tooth, and motor is arranged on left side in outer leg, and outer leg lower end has a through hole, motor gear combines with interior leg toothrow, switch input terminal is connected with power line, and output is connected with motor, and power-line plug via through holes extends out.Power line is electrically connected with room and is energized, and does not put by green switch, motor power conducting, and motor rotates forward and drives toothrow by interior leg after downward-extension, when after interior leg and floor contact, and trip switch, motor quits work; When interior leg inwardly being regulated, pin red switch, motor conducting, motor reversal drives toothrow to be moved up by interior leg, when interior leg is parallel with outer leg, unclamps red switch, motor power-off, has the effect steadily not regulating chair leg height from dynamic independence according to ground.

Switch in described is two-way switch.

Switch in described divides red and green two buttons.

Described button and switch balance.

The diameter 1cm of described button.

Through hole internal diameter in described is 2cm.

Described toothrow is corresponding with the gear of motor.

Described motor revolves and takes two turns, interior leg decline 0.5cm.

The Right Inboard of described outer leg is stained with a slat gum skin, and during excessive generation deflection stressed for interior leg, effective combination of leg and outer leg in ensureing, makes interior leg when stressed, can not move in outside leg.

Beneficial effect: efficiently solve seat leg and independently regulate upper and lower function, to ensure that every root chair leg can contact with ground 100%.

Accompanying drawing explanation

Fig. 1 is a kind of interior leg of electric lifting chair leg schematic diagram parallel with at the bottom of outer leg.

Fig. 2 is the schematic diagram that a kind of interior leg of electric lifting chair leg stretches.

1. outer legs in figure, leg 2., 3. power line, 4. motor, 5. through hole, 6. switch, 7. rubber bar.

Detailed description of the invention

A kind of electric lifting chair leg of the present invention, structure comprises: outer leg 1, interior leg 2, power line 3, motor 4, through hole 5, switch 6, rubber bar 7.

In FIG, leg 2 in installing in outer leg 1, on the left of interior leg 2, middle-end is provided with several rows of tooth, motor 4 is arranged on left side in outer leg 1, and outer leg 1 lower end has a through hole 5, and motor 4 gear combines with interior leg 2 toothrow, switch 6 input is connected with power line 3, output is connected with motor 4, and power line 3 plug via through holes 5 extends out, and the Right Inboard of outer leg 1 is stained with a slat gum skin 7.

In fig. 2, each assembly is installed consistent with Fig. 1 with position, but interior leg 2 stretches, the outer leg 1 of booster seat.
