Problems solved by technology
[0002] When the ground is uneven, the chair legs of the seat will be unstable, causing people to sit on the chair wobbly, and the seats in the current market do not have the function of freely extending and adjusting the chair legs on the legs, so it is difficult for people to sit on the chair. Inconvenience in use
[0003] After retrieval, publication number: CN201624348U utility model patent, patent name: foldable and telescopic chair, its content also expresses that the chair legs can move up and down, but its function is to rise and fall as a whole, which cannot solve the needs caused by uneven ground The chair legs are of different heights, and at the same time, its structure is only fixed by bolts

Embodiment Construction
[0018] The invention provides an adjustable seat leg, which comprises: an outer leg 1, an inner leg 2, a friction plate 3, a motor 4, a trapezoidal gear 5, a switch 6, a storage battery 7, and a chute 8.
[0019] exist figure 1 Among them, a movable inner leg 2 and a control device for adjusting the tightness of the inner leg 2 are installed in the outer leg 1. The control device is to fix a friction plate 3 on the right side of the trapezoidal gear 5, and the back of the trapezoidal gear 5 is movably installed on the chute 8, the rack of the trapezoidal gear 5 corresponds to the gear of the motor 4, the input end of the switch 6 is connected to the storage battery 7, and the output end is connected to the motor 4.
[0020] The friction plate 3 is fastened together with the inner leg 2 .
[0021] exist figure 2 , the components are mounted and positioned with figure 1 The same, but the inner leg 2 extends downward, and the extension of the inner leg 2 can be adjusted.

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 [0001] The invention relates to a chair leg height adjustment function of a seat, in particular to an adjustable seat leg. Background technique [0002] When the ground is uneven, the chair legs of the seat will be unstable, causing people to sit on the chair wobbly, and the seats in the current market do not have the function of freely extending and adjusting the chair legs on the legs, so it is difficult for people to sit on the chair. Inconvenience in use. [0003] After retrieval, publication number: CN201624348U utility model patent, patent name: foldable and telescopic chair, its content also expresses that the chair legs can move up and down, but its function is to rise and fall as a whole, which cannot solve the needs caused by uneven ground The legs of the chair are of different heights, and at the same time, its structure is only fixed by bolts. Contents of the invention [0004] The purpose of the present invention is to provide an adjustable s...
