The specific implementation mode is as follows:

the first embodiment is as follows:

referring to fig. 1 and 2, the massage chair integrated track, referred to as track 10 for short, includes a track portion 1 and a rack portion 2, the track portion 1 and the rack portion 2 are formed by plastic integrally formed curved structures; the section of the rail 10 has parallel upper and

lower edges

11, 12 and a vertical wall 13 connecting the upper and lower edges; the rack part 2 is positioned at the outer side of the lower edge 12, and a track part 1 is formed between the inner side of the lower edge 12 and the vertical wall 13; more specifically, the rail portion 1 is higher than the tooth crest of the rack portion 2 and not higher than 20mm, which can solve the rigidity strength of the rail 10; the width of the upper edge 11 of the track is equivalent to the width of the track part 1, in other words, the upper edge 11 is narrower than the lower edge 12.

Furthermore, two reinforcing ribs 14 along the track direction are formed at the bottom of the lower edge 11 of the track, the outer track reinforcing rib 14 is positioned at the side of the lower edge 11, the inner track reinforcing rib 14 is positioned at the bottom of one side of the track part at the junction of the track part 1 and the rack part 2, and the reinforcing and supporting effect on the track part 1 and the rack part 2 is formed; a plurality of connecting ribs 15 are distributed between the two reinforcing ribs 14, and a bolt seat 16 is formed at the intersection of part of the connecting ribs 15 and the reinforcing ribs 14 for locking a positioning bolt or a screw. The bolt seat 16 in this example is at the bottom of the rail, near the middle.

In addition, an upward reinforcing rib 14 is also formed on the side edge of the upper edge 11 of the track, part of connecting ribs 15 surround the vertical wall from the bottom of the lower edge and are connected with the reinforcing rib 14 on the upper edge, and a C-shaped structure is wrapped on the outer side of the track 10, so that the track is more stable integrally. And the reinforcing ribs 14 and the connecting ribs 15 are flush in surface and are lapped on the back 31 of the channel steel to form support together.

Referring to fig. 3 to 7, a rail assembly comprises the rail 10 and the channel 3 which are integrally formed, wherein the channel 3 has a curved structure matched with the rail 10, and the section of the channel 3 is Jiong with a downward notch; through holes 32 are formed in the ridge 31 of the channel steel corresponding to the bolt seats 16 of the rails, and the rails 10 are supported by the aid of the whole ridge 31 of the channel steel. Compared with the traditional U-steel 3, the door-shaped channel steel is easier to form, has low process requirements, can ensure the accurate and smooth curved shape of the back 31, has balanced bilateral symmetry stress, and greatly improves the bearing capacity and the shock resistance, thereby being one of the advantages of the structure.

Furthermore, except for a circular hole, the through holes 32 formed in the channel steel 3 are slotted holes, and an alignment reference is formed by the circular hole and the bolt seat 16 on the rail, while the other slotted through holes 32 allow the rail 10 to provide a borrowing margin when the rail is deformed due to stress or cold and hot deformation in the operation process, and facilitate the bolt seat 16 to enter the hole; during assembly, the gasket 4 and the bolt 5 enter from a groove at the bottom of the channel steel 3 and are locked by a tool; the rail 10 rests on the back 31 of the channel by means of the bottom reinforcement 14 and the tie bars 15, and is supported by the channel 3.

Example two:

referring to fig. 9 and 10, in this example, bolt seats 16 are formed on both sides of the rail 10 to form a function of clamping the channel steel; specifically, a reinforcing rib 14 along the track direction and a plurality of transverse connecting ribs 15 are formed at the bottom of the lower edge 12 of the track, and part of the connecting ribs 15 are thickened and provided with two bolt seats 16, namely the bolt seats 16 are distributed at two ends of the bottom connecting rib 15.
