The specific implementation mode is as follows:

referring to fig. 1 to 5, the anti-occupying massage chair comprises a base frame 1, a seat frame 2, legs 3, an occupying rack 4 and a driving assembly 5; the seat frame 2 can be movably arranged above the underframe 1, and the leg frame 3 can be rotatably hung at the front end of the seat frame 2; the occupying frame 4 is axially positioned at the front edge of the seat frame 2 and driven by the driving component 5 to swing, so that the switching between the occupying-preventing state and the sitting state is realized.

The occupying rack 4 is provided with two separate frames 41 and a cross bar 42 connecting the two frames, wherein the frames 41 are hinged at the front end of the seat frame 2 and can synchronously swing on the surface of the body-contacting seat frame 2 for sitting and can be tilted at the front edge of the seat frame 2 to prevent the occupying rack from switching between two states, as shown in fig. 3 and 4; more specifically, the cross bar 42 in the placeholder 4 serves to associate the two frames 41, constitutes a synchronous rigid structure, and is rotatably positioned on the seat frame's hand rail 21 by means of a protruding shaft 43 outside the frames 41.

The driving assembly 5 comprises an electric push rod 51 and a swinging frame, wherein the swinging frame is provided with crank arms 52 with bilateral symmetry and a cross beam 53 connected with the crank arms, the cross beam 53 is connected between lower arm sections 521 of the crank arms, and the ends of upper arm sections 522 of the crank arms are positioned with rollers 54. More specifically, the crank arm 52 is formed by welding two square tubes, and a connecting rod 523 is further welded between the upper arm section 522 and the lower arm section 521 to form a triangular structure, so that the rigidity and the strength of the crank arm 52 are ensured, and the crank arm can bear larger pressure.

One end of an electric push rod 51 is hinged below the seat frame 2, the other end of the electric push rod is hinged on a cross beam 53 of the swing frame, inflection points of crank arms 52 on two sides of the swing frame are correspondingly hinged on two sides of the seat frame 2, the crank arms 52 are driven by the electric push rod 51 to swing, and upper arm sections 522 of the crank arms are tilted and abut against the jacking frame 41 by virtue of rollers 54 positioned at the end parts, as shown in fig. 4.

Further, the frame 41 and the cross bar 42 in the occupying rack 4 are formed by processing and welding square pipes, and are respectively wider than two sides of the seat frame 2 to form a square pipe position, so that the occupying rack can be supported when being attached to the surface of the seat frame 2, and can be abutted to the upper roller 54 of the crank arm which is positioned between the outer side of the seat frame 2 and the armrest frame 21 and swings.

The cross beam 53 in the swing frame is welded between the ends of the lower arm sections 521 of the two crank arms, a jacking roller 55 is further arranged forward of the cross beam 52, and the jacking roller 55 can abut against the back of the leg frame 3 in the process of forward extension of the electric push rod 51 and jack up the leg frame 3. That is, the electric push rod 51 has two strokes, extends out of the initial segment, drives the swing frame to lift off the support for the occupying rack 4, and meets the requirement of sitting, as shown in fig. 3; the tail section is extended out, the swinging frame is continuously driven to jack the leg frame 3 to act, the legs and the feet can be laid flat, and the human body can be in a lying state, so that the electric push rod 51 has double functions, is used for switching the state of the occupied frame 4 and can also drive the leg frame 3 to act, the two actions are not interfered with each other, and meanwhile, the seat frame 2 acts to form a more flexible combination, the defect of linkage between the traditional leg frame 3 and the seat frame 2 is overcome, and the two purposes are achieved by one action.
