Description

Movable underframe and massage chair Technical Field The utility model relates to a movable underframe for a massage chair and the massage chair. Background The massage volume is larger, when the underframe of the massage chair is contacted with the ground, the anti-skid blocks are arranged on the underframe in order to reduce the movement of the massage chair, and the purpose is to improve the stability of the massage chair on the ground; However, when the massage armchair needs to be changed in use position, especially when the massage armchair needs to be moved for the family user, the massage chair is very laborious for the user to directly push the massage due to the large volume of the massage chair. Disclosure of utility model The first object of the present utility model is to provide a mobile chassis, which allows a user to push a massage chair easily and with little effort. The technical aim of the utility model is realized by the following technical scheme: A movable underframe comprises a frame body, a rotating pipe, a trundle, a power piece and a supporting frame body, wherein the rotating pipe is rotatably connected to the frame body, the trundle is arranged on the rotating pipe, the power piece drives the rotating pipe to rotate so as to drive the trundle to synchronously and vertically rotate, when the trundle rotates to the upper side, the trundle is separated from the ground, and when the trundle rotates to the lower side, the trundle supports the frame body. Preferably, the power piece is an electric push rod, one end of the electric push rod is hinged to the frame body, and the other end of the electric push rod is hinged to the rotating pipe. Preferably, there are at least two casters on the swivel tube. Preferably, the frame body is provided with rollers and foot pads, the foot pad supports the frame body when the casters are arranged above, the rollers and the ground are suspended, and the foot pads are suspended when the casters are arranged below, and the casters and the rollers obliquely support the bracket. Preferably, the number of the foot pads is two, and one group of foot pads, the caster wheels, the other group of foot pads and the rollers are sequentially arranged along the length direction of the frame body. Preferably, the foot pad is provided with a counter bore, and a first screw fixed on the frame body is arranged in the counter bore. Preferably, the lower surface of the frame body is fixedly provided with a dovetail block, the upper surface of the foot pad is provided with a dovetail groove, the dovetail block is inserted into the dovetail groove to fix the foot pad and the frame body, and the left side and the right side of the frame body are fixedly provided with sealing plates for sealing the end parts of the dovetail groove through second screws.
