[0035] As shown in Figs. 1-3 The embodiment provides a stair climbing machine which can be quickly folded and unfolded, comprising:

[0036] A first support frame 1 is provided.

[0037] A second support frame 2 is hinged to the upper end of the first support frame 1, and left and right two groups of foot pedal assemblies 21 are slidably arranged on the second support frame 2, a pull rope 22 is arranged between the two groups of foot pedal assemblies 21, a winding wheel 23 is arranged on the second support frame 2, and the pull rope 22 winds around the winding wheel 23; specifically, the winding wheel 23 is located at the upper end of the second support frame 2 and the number is two; and

[0038] An auxiliary frame 3 is arranged between the first support frame 1 and the second support frame 2, the auxiliary frame 3 comprises two hinged frames 31, the two hinged frames 31 are hinged together at one end close to each other, and the other ends of the two hinged frames 31 are hinged to the first support frame 1 and the second support frame 2 respectively.

[0039] The stair climbing machine comprises a folded state and an unfolded state; when the stair climbing machine is switched from the folded state to the unfolded state, the lower ends of the first support frame 1 and the second support frame 2 are opened away from each other, and the two hinged frames 31 are unfolded, when used in the unfolded state, the user steps on the two groups of foot pedal assemblies 21 with both feet, so as to drive the two groups of foot pedal assemblies 21 to alternately tilt and slide up and down along the second support frame 2; when the stair climbing machine is switched from the unfolded state to the folded state, the first support frame 1 and the second support frame 2 are folded close to each other, since the two hinged frames 31 are hinged to each other, and the two hinged frames 31 are folded close to each other synchronously. The included angle of the two hinged frames 31 is 180 degrees in the unfolded state.

[0040] In one specific embodiment, as Figs. 1-3As shown in the figure, the auxiliary frame 3 is arranged between the lower end of the first support frame 1 and the lower end of the second support frame 2. Specifically, the ends of the two hinged frames 31 away from each other are hinged to the lower end of the first support frame 1 and the lower end of the second support frame 2, respectively.

[0041] In a specific embodiment, the auxiliary frame 3 can also be arranged between the middle of the first support frame 1 and the middle of the second support frame 2. Specifically, when the stair climber is in the unfolded state, the unfolded auxiliary frame 3 is preferably parallel to the ground, so that the stair climber has better stability.

[0042] In a specific embodiment, as shown in the figure, Figs. 1-3 The auxiliary frame 3 is two, and the two auxiliary frames 3 are located on the left and right sides of the first support frame 1, and when the stair climber is in the unfolded state, the two auxiliary frames 3 are parallel to each other.

[0043] In a specific embodiment, as shown in the figure, Figs. 1-3 The auxiliary frame 3 has several, and the several auxiliary frames 3 are arranged from top to bottom along the first support frame 1, and when the stair climber is in the unfolded state, the several auxiliary frames 3 are parallel to each other.

[0044] In this embodiment, as shown in the figure, Figs. 1-3 In order to make the two hinged frames 31 located between the first support frame 1 and the second support frame 2 after folding, the specific scheme is that a hinge seat 32 is arranged between the two hinged frames 31, the front and rear sides of the hinge seat 32 are provided with hinge grooves with notches facing downward, and each hinged frame 31 is hinged in the corresponding hinge groove through a pin shaft. When folding, the hinged frame 31 rotates relative to the hinge groove, so that the hinge seat 32 moves upward, and then the two hinged frames 31 are located between the first support frame 1 and the second support frame 2 after folding.

[0045] In order to facilitate the hinging of the two ends of the auxiliary frame 3 to the first support frame 1 and the second support frame 2, respectively, the first support frame 1 and the second support frame 2 are provided with a connecting seat 4, and the connecting seat 4 is provided with two lugs, and the two ends of the auxiliary frame 3 are hinged between the two lugs of the connecting seat 4 corresponding to the hinge seat 32 through a pin shaft.

[0046] The upper end of the first support frame 1 is provided with two hinged parts on the left and right sides, respectively, and the upper end of the first support frame 1 is hinged to the two hinged parts through two pin shafts.

[0047] In a specific embodiment, as shown in the figure, Figs. 1-3As shown, in order to achieve better fitness effect, the damping frame 5 is arranged between each set of the foot pedal assembly 21 and the first support frame 1, and the two ends of the damping frame 5 are respectively hinged with the foot pedal assembly 21 and the first support frame 1. Preferably, the damping frame 5 is hinged with the lower end of the first support frame 1, and the damping frame 5 can be an extension oil cylinder. When the user drives the two sets of foot pedal assemblies 21 to alternately tilt and slide up and down, the damping frame 5 plays a certain damping role, so that the user can achieve better fitness effect.

[0048] In one embodiment, as Figs. 1-3 As shown, the first support frame 1 is provided with a handrail frame 11, the handrail frame 11 comprises two left and right supporting rods and a handrail rod connected to the upper ends of the two supporting rods, and the two supporting rods are telescopically connected with the first support frame 1 and fixed by bolts. The user can adjust the height of the handrail frame 11 by extending the handrail frame 11 out of the first support frame 1 or retracting the handrail frame 11 into the first support frame 1. The first support frame 1 is provided with a timer, a counter and / or a mobile phone support. Specifically, it can be used for facilitating the user to count and time, etc.

[0049] Working principle:

[0050] When the stair climbing machine is switched from the folded state to the unfolded state, the user can drive the lower end of the first support frame 1 and the lower end of the second support frame 2 to move away from each other, and at the same time, the two hinged frames 31 are driven to unfold to make the two hinged frames 31 present 180 degrees; when the stair climbing machine is switched from the unfolded state to the folded state, the user can drive the first support frame 1 and the second support frame 2 to move close to each other, and since the two hinged frames 31 are hinged with each other, the two hinged frames 31 are driven to move close to each other synchronously.

[0051] The utility model is not limited to the above optional implementation, and the schemes can be combined arbitrarily on the premise of not being contradictory to each other; anyone can derive other various forms of products under the inspiration of the utility model, but no matter any change in shape or structure, any technical scheme falling within the scope defined by the claims of the utility model falls within the protection scope of the utility model.
