[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1-4 As shown in the figure, a guide rail and a backrest that are convenient for disassembling and assembling the movement include a guide rail body 1, a guide rail rack 2 is fixed on the inner side of the guide rail body 1, a guide rail opening 3 is opened at the end of the guide rail body 1, a connecting piece 4 is welded on the side of the guide rail opening 3, a guide rail block 5 is fixedly installed on the inner side of the connecting piece 4, a walking movement 6 is installed in the middle of the guide rail body 1, and walking mechanisms 7 are provided on both sides of the walking movement 6. A fixing block 12 is welded on the outer side of the middle section of the guide rail body 1.

[0022] The guide rail rack 2 is symmetrically arranged along the central axis of the guide rail body 1, and guide rail openings 3 are symmetrically opened on both sides of the same end of the guide rail body 1, which can ensure that the central movement is guided and moved through stable control, ensuring the stability of the direction and position of movement.

[0023] The guide rail stopper 5 is connected to the connecting piece 4 by bolts, and the width of the guide rail stopper 5 is greater than the width of the guide rail opening 3. The guide rail stopper 5 is fixed to the guide rail opening 3 by bolts to ensure that the opening is filled to prevent it from falling out when the middle movement of the equipment moves.

[0024] The traveling mechanism 7 includes a front traveling wheel 701 , a gear sleeve rod 702 and a rear traveling wheel 703 . The side of the front traveling wheel 701 is coaxially connected to the gear sleeve rod 702 , and the rear traveling wheel 703 is installed behind the front traveling wheel 701 .

[0025] The gear sleeve rod 702 forms a rotating structure between the front traveling wheel 701 and the traveling movement 6, and the traveling movement 6 forms a translation structure between the rear traveling wheel 703 and the guide rack 2. Under the guidance of the guide rack 2, it gradually moves toward the guide rail opening 3. After the movement reaches the guide rail opening 3, it is stopped by the electronically controlled tooling to facilitate the subsequent manual removal operation of the movement.

[0026] Example 2

[0027] like Figure 1-4 As shown, this embodiment further illustrates Example 1. The massage chair backrest shown in the figure includes a blow-molded backrest 8, a baffle mounting groove 9, a blow-molded baffle 10, a mounting piece 11, and a guide rail for convenient disassembly and assembly of the movement according to any one of the guide rail body 1 to the guide rail block 5 of the claim. The blow-molded backrest 8 is installed on the top of the guide rail body 1 in a fitting arrangement. Baffle mounting grooves 9 corresponding to the position of the guide rail opening 3 are provided on both sides of the end of the blow-molded backrest 8. A blow-molded baffle 10 is fixedly installed in the middle of the baffle mounting groove 9 by bolts. A mounting piece 11 corresponding to the position of the fixing block 12 is provided at the bottom of the middle section of the blow-molded backrest 8. The external backrest is conveniently and stably connected to the internal guide rail for installation, and the shapes match each other, resulting in a better installation and fitting effect, ensuring the stability of subsequent overall equipment assembly and use, and convenient disassembly and assembly are conducive to subsequent maintenance operations.

[0028] Working principle: First, remove the guide rail block 5, and then remove the blow molding baffle 10, and then control the walking movement 6 through the electronic control tooling to move toward the guide rail opening 3 where the guide rail block 5 is installed on the guide rail body 1. The movement drives the gear sleeve rod 702 under the drive of the internal motor, and gradually moves toward the guide rail opening 3 under the guidance of the guide rail rack 2. After the movement reaches the guide rail opening 3, it is stopped by the electronic control tooling and then the two front walking wheels 701 of the movement close to the guide rail opening 3 are slowly taken out by hand, and then the other two rear walking wheels 703 are moved close to the guide rail opening 3 under manual control and taken out. Conversely, the installation steps can be reversed. The overall equipment is convenient to disassemble and assemble, and the internal walking movement 6 is controlled to automatically retract to ensure that it can be flexibly and conveniently removed, which is convenient and fast for the replacement and maintenance of the middle movement.

[0029] Next, the blow-molded backrest 8 is aligned and disassembled with the fixing blocks 12 on the guide rail body 1 through the mounting pieces 11 on both sides of the bottom, which can quickly and stably align the positioning backrest and the guide rail for disassembly and assembly, ensuring that the connection position is accurately aligned and the installation is stable and convenient. The disassembly and assembly of the blow-molded baffle 10 on the inside of the baffle mounting groove 9 can cooperate with the guide rail opening 3 on the guide rail body 1 to disassemble and use the middle walking movement 6, making the appearance beautiful. The detachable equipment ensures that the middle walking movement 6 can be quickly and conveniently disassembled and maintained, and the operation is flexible, convenient and easy to use.
