When the rear running board 122 is rotatably folded around the first connecting member 13 at the lower end of the front running board 121, the running belt 3 stretched by the roller 2 becomes loose due to the folding of the running board, and by providing the U-shaped baffle 16, the loose running belt 3 can be accommodated in the U-shaped groove of the U-shaped baffle 16, preventing the running belt 3 from falling.

As shown in fig. 10 to 11, in order to provide a third embodiment of the foldable walking machine of the present invention, the difference between the present embodiment and the first embodiment is: the first connecting member 13 is configured differently.

In this embodiment, the first connecting assembly 13 includes a hinge assembly 138, and the rear treadmill 122 is hinged to the front treadmill 121 through the hinge assembly 138. When the walking machine is not in use, the rear running platform 122 can be rotatably folded around the hinge assembly 138 to be folded at the lower end of the front running platform 121, namely, the rear running platform 122 and the front running platform 121 are folded together to reduce the length of the walking machine, so that the walking machine is convenient to transport, the transportation cost is reduced, and the folded walking machine occupies a small space.

The hinge assembly 138 comprises two hinge connecting blocks 1381, a connecting shaft sleeve 1382 and a connecting shaft rod 1383; the opposite ends of the two hinge connecting blocks 1381 are respectively provided with at least one connecting ring 1385, and a connecting shaft sleeve 1382 is inserted into the connecting rings 1385 of the two hinge connecting blocks 1381 to hinge the two hinge connecting blocks 1381; the connecting shaft 1383 is screwed with the connecting sleeve 1382 to fix the connecting sleeve 1382 to the connecting ring 1385; the one end that two hinge connecting blocks 1381 carried on the back is connected to respectively before running platform 121 and back and runs platform 122. During the use, preceding platform 121 and the back platform 122 of running can both run and rotate around connecting axle sleeve 1382 through hinge connecting block 1381 in order to cooperate the folding up of running platform 12, and preceding platform 121 and the back platform 122 of running rotate the in-process, and two hinge connecting blocks 1381 then rotate around connecting axle sleeve 1382 through go-between 1385, and connecting axostylus axostyle 1383 then can avoid connecting axle sleeve 1382 and break away from go-between 1385 and break down at hinge connecting block 1381 rotation in-process.

The opposite ends of the two hinge connecting blocks 1381 are respectively provided with at least two connecting rings 1385, a hinge groove 1386 is arranged between two adjacent connecting rings 1385, and the connecting ring 1385 of one hinge connecting block 1381 is arranged in the hinge groove 1386 of the other hinge connecting block 1381. When the folding table is used, the side wall of the hinge groove 1386 has the limiting and guiding effect on the connecting ring 1385 in the hinge groove 1386, and can assist in matching to rotatably fold the rear running table 122 at the lower end of the front running table 121, so that the rear running table 122 can be more smoothly and stably rotatably folded.

The hinge assembly 138 further includes a third flat washer 1384, and the third flat washer 1384 is disposed about the connecting shaft 1383. By providing a third flat washer 1384 to protect the surface of the coupling ring 1385 from scratches by the connecting shaft 1383, pressure on the coupling ring 1385 by the connecting shaft 1383 is dissipated.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
