Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-4, the utility model provides a multifunctional lifting chair, which comprises a foot base 1, wherein a lifting mechanism is arranged on the foot base 1, the lifting mechanism comprises a pneumatic rod 31 arranged in the middle of the foot base 1, a lifting rod 32 capable of lifting is arranged at the output end of the pneumatic rod 31, the other end of the lifting rod 32 is connected to a supporting seat 33, and an adjusting handle 34 connected with the lifting rod 32 is arranged in an opening of the side wall of the supporting seat 33;

the top of the supporting seat 33 is connected with a cushion 4, the tail of the cushion 4 is provided with a chair back 5, and the front surface of the chair back 5 is provided with a pressure sensor 6.

In this embodiment, a lifting mechanism is disposed on the chair, the lifting mechanism can adjust the height of the cushion 4, when a user sits on the cushion 4, the user presses down at the opening of the side wall of the supporting seat 33 through the adjusting handle 34 to make the user abut against the lifting rod 32, under the action of gravity, the lifting rod 32 contracts towards the inner cavity of the pressure rod 31, the supporting seat 33 descends to drive the cushion 4 to reduce the height, otherwise, the user leaves the cushion 4, the user presses down at the opening of the side wall of the supporting seat 33 through the adjusting handle 34 to make the user abut against the lifting rod 32, under the action of air pressure thrust, the lifting rod 32 moves towards the upper part of the output end of the pressure rod 31, the supporting seat 33 lifts to drive the cushion 4 to lift, the height of the chair can be automatically adjusted according to use requirements, and the applicability of the chair to people with different heights is improved.

It should be noted that: 1. the supporting seat 33 is a thickened steel plate, so that the cylinder explosion of the air pressure rod 31 under the pressure imbalance is prevented, and the lifting rod 32 is triggered to impact the cushion 4 to cause personal injury to a user;
