[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-7 A folding structure for a treadmill handrail includes a handrail unit 1, a positioning shaft 2, and a connecting shaft 3.

[0025] The positioning shaft 2 is used to position the handrail unit 1. Specifically, the positioning shaft 2 is fixed on the treadmill body 4. As one option, corresponding positioning shafts 2 are fixed on the left and right walls of the treadmill body 4 respectively.

[0026] For the armrest unit 1, its lower end includes a first groove 51 that mates with the positioning shaft 2, wherein the outer end of the first groove 51 is open, as shown in the figure. Figure 4 In the direction shown, the outer end of the first groove 51 can be understood as the lower end of the first groove. In actual use, the armrest unit 1 can be locked by aligning the first groove 51 with the positioning shaft 2 and placing the positioning shaft 2 into the first groove 51. Of course, the shape of the positioning shaft 2 is square or polygonal, and the shape of the first groove 51 is adapted to the shape of the positioning shaft 2.

[0027] Specifically, to unlock the armrest unit 1, the positioning shaft 2 is disengaged from the first groove 51 by lifting the armrest unit 1; after the positioning shaft 2 is aligned with the first groove 51, the armrest unit 1 is released and, due to gravity, it falls, thus locking the armrest unit 1.

[0028] In this embodiment, the armrest unit 1 has an unfolded first state and a folded second state. The cooperation between the positioning shaft 2 and the first groove 51 can at least be used to lock the armrest unit 1 in the unfolded first state. Of course, in the folded second state, the armrest unit 1 can also be locked by the cooperation between the positioning shaft 2 and the first groove 51.

[0029] To facilitate the switching between the unfolded and folded states of the handrail unit 1, the handrail unit typically needs to be rotatably mounted on the treadmill body 4. To accommodate the aforementioned locking method, in this embodiment, the lower end of the handrail unit 1 includes a first elongated groove 52. A connecting shaft 3 is fixedly mounted on the treadmill body 4, passing through the first elongated groove 52. Through the cooperation between the connecting shaft 3 and the first elongated groove 52, the rotation of the handrail unit 1 can be realized, and the necessary space can also be provided for the lifting and unlocking movement of the handrail unit 1. That is, when the handrail unit 1 falls to the locked state, the connecting shaft 3 is located in the upper half of the first elongated groove 52, and when the user lifts the handrail unit 1, the connecting shaft 3 is correspondingly arranged in the lower half of the first elongated groove 52, so that the handrail unit 1 can rotate and move up and down relative to the connecting shaft 3.

[0030] Furthermore, the positioning shaft 2 is arranged below the connecting shaft 3. The connecting shaft 3 includes a mating part 31 with an outer diameter smaller than its main body. The mating part 31 is arranged at the first long groove 52. The mating part 31 is circular in shape, and its outer diameter is adapted to the width of the first long groove 52, so that the handrail unit 1 can rotate around the outer diameter of the mating part 31 on the connecting shaft 3.

[0031] To prevent the handrail unit 1 from falling off the connecting shaft 3, in this embodiment, a limiting piece 32 with an outer diameter larger than the mating part is provided at the outer end of the connecting shaft 3. The limiting piece 32 is positioned at the outer end of the connecting shaft 3 by a fastener 33 that mates with the connecting shaft 3. For example, a threaded hole is opened on the outer wall of the connecting shaft 3, and the fastener 33 is threadedly installed at the threaded hole to position the limiting piece 32. As one option, the limiting piece 32 is a gasket.

[0032] To further improve the positioning effect of the handrail unit 1 in the unfolded state, in this embodiment, a limiting shaft 6 is fixed on the treadmill body 4 on one side of the connecting shaft 3.

[0033] The handrail unit 1 can be selected from common handrail types in the prior art. This embodiment provides a detailed description of one type of handrail. Specifically, the handrail unit 1 includes a handrail body and a connector 5 fixed to the lower end of the handrail body. The first groove 51 and the first elongated groove 52 are both formed on the connector 5. Figure 5 As shown, the first groove 51 is formed at the lower end of the connector 5, and the first long groove 52 is formed above the first groove 51.

[0034] Furthermore, the handrail body includes a first column 11 arranged on the left side of the treadmill body 4, a second column 12 arranged on the right side of the treadmill body 4, and a crossbar 13 arranged between the first column 11 and the second column 12. The first column 11, the second column 12 and the crossbar 13 are integrally formed or welded together.

[0035] Corresponding connectors 5 are fixedly installed at the lower ends of the first column 11 and the second column 12, respectively, to cooperate with the positioning shaft 2 and the connecting shaft 3 respectively fixed on the left and right side walls of the treadmill body 4.

[0036] In this embodiment, the lower end of the armrest unit 1 is fixed with an outer shell 7 for hiding the connector 5. The outer shell 7 includes a second groove 71 corresponding to the first groove 51 and a second long groove 72 corresponding to the first long groove 52.

[0037] The second groove 71 is used for the insertion of the positioning shaft 2, and the second long groove 72 is used for the insertion of the connecting shaft 3. Of course, the outer shell 7 may include a left shell 73 and a right shell 74 that are assembled and cooperate with each other. The left shell 73 is located on the left side of the column on the handrail unit 1 (between the column and the treadmill body), and the right shell 74 is located on the right side of the column on the handrail unit. The second long groove 72 is opened on the left shell 73, and the second groove 71 is opened on both the left shell 73 and the right shell 74. After the two are assembled, they form a groove combination that cooperates with the positioning shaft 2.

[0038] In one embodiment, the outer shell 7 can be fixed to the connector 5 or the corresponding column by fasteners, while the limiting shaft 6 can directly cooperate with the outer wall of the outer shell 7.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
