Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports and fitness equipment technology, and in particular to a mountaineering machine. Background Technology
[0002] Among sports and fitness equipment, the stair climber is a multi-functional aerobic training fitness machine that simulates mountain climbing. It is named for its similarity to mountain climbing and is a fitness product that appeared after the treadmill. Its main principle is that the exerciser uses the continuous back-and-forth movement of both feet on a machine with a large incline to imitate outdoor mountain climbing and thus achieve fitness goals. Existing foot pedals typically achieve alternating forward and backward movement via a pull rope (steel wire or similar). For example, Chinese utility model patent CN201012244Y discloses an adjustable pedaling force stair climber. The stepping mechanism includes a transmission belt and two fixed pulleys mounted on the left and right sides of the upper support frame. A friction adjustment mechanism, in contact with the transmission belt, is installed between the two pulleys. This mechanism uses a combination of a resistance wheel and a component controlling its rotation, allowing for convenient adjustment of multiple resistance levels. This allows trainees to freely choose their training intensity. While existing friction adjustment mechanisms do exist, their complex structure, requiring multiple resistance wheels and other components, significantly increases manufacturing difficulty. Furthermore, the use of a transmission belt for alternating left and right foot pedal movement doesn't adequately meet the user's resistance needs during operation. Therefore, improvements are necessary. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0032] Example 1: See Figure 1 , Figure 2 , Figure 6 and Figure 7 A climbing machine includes a frame 1 and a fixed handrail frame 2 mounted on the frame 1. The frame 1 has a left foot pedal 3 and a right foot pedal 4 that move back and forth alternately. A combined hydraulic cylinder structure 5 is mounted on the frame 1, driving the corresponding left foot pedal 3 and right foot pedal 4 to move back and forth alternately. An adjuster 6 is mounted on the combined hydraulic cylinder structure 5, allowing adjustment to accommodate the needs of different users. This invention not only overcomes the problem of poor resistance in traditional foot pedal transmission methods using pull ropes (steel wire ropes or other wires), but also allows for easy adjustment of resistance according to individual needs, further enhancing user satisfaction.
[0033] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the integrated hydraulic cylinder structure 5 is located at the upper part of the back of the frame 1. The integrated hydraulic cylinder structure 5 includes a pair of hydraulic cylinders 51 arranged on the frame 1. The pair of hydraulic cylinders 51 are connected by an oil pipe 52. One of the hydraulic cylinders 51 is equipped with an adjuster 6. The lower part of one hydraulic cylinder 51 is connected to a left foot pedal 3, and the lower part of the other hydraulic cylinder 51 is connected to a right foot pedal 4. In use, as long as the left foot pedal 3 or the right foot pedal 4 moves downward, the medium (hydraulic oil) in the corresponding hydraulic cylinder 51 is squeezed into the other hydraulic cylinder 51. Then, the corresponding right foot pedal 4 or left foot pedal 3 in the other hydraulic cylinder 51 is driven upward. In this way, the left foot pedal 3 and the right foot pedal 4 move back and forth alternately. This overcomes the problem of poor resistance effect of traditional foot pedals with pull ropes (steel wire rope or steel wire, etc.). Moreover, the resistance can be easily adjusted according to individual needs through the adjuster 6, which is more conducive to meeting the user's needs. Further explanation: The hydraulic cylinder 51 includes a cylinder body 511. A sealing connector 512 is provided at one end of the cylinder body 511, and a cylinder seat 513 is provided at the other end. A piston rod 514 extends from the cylinder seat 513 into the interior of the cylinder body 511. A piston 515 is provided on the end face of the piston rod 514 inside the cylinder body 511. A connector 516 is provided on the end face of the piston rod 514 outside the cylinder body 511. The connector 516 is fixed to either the left foot pedal 3 or the right foot pedal 4. A sealing plug 517 is provided on the piston rod 514 in the cylinder seat 513. The sealing plug 517 and the interior of the cylinder body 511 are filled with a medium (hydraulic oil). The cylinder seat 513 is equipped with a connector 518 for connecting the oil pipe 52. This arrangement allows the cylinder body 511, located between the cylinder body 511 and the cylinder seat 513, to be filled with a medium. In this embodiment, when the left foot pedal 3 or the right foot pedal 4 is pressed downwards, the medium in one cylinder 51 is forced through the oil pipe 52 to be transported to the other cylinder 51, thereby causing the right foot pedal 4 or the left foot pedal 3 to move upwards. This alternating movement of the left foot pedal 3 and the right foot pedal 4 increases the resistance, which is more beneficial for the user's exercise. At the same time, the regulator 6 allows for adjustment of the oil circuit size, thus adapting to the needs of different users. Furthermore, two cylinders 51 are arranged in pairs, which facilitates better coordination with the alternating movement of the left foot pedal 3 and the right foot pedal 4.
[0034] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing connector 512 adopts an L-shaped sealing seat, which is advantageous for installation on the upper surface of the frame 1.
[0035] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connector 516 uses a retaining ring, which facilitates installation with the left foot pedal 3 or the right foot pedal 4.
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the regulator 6 is installed on the cylinder seat 513 of a hydraulic cylinder 51, which makes the operation easier and simpler.
[0037] Example 3: This can be explained based on Example 1, such as... Figure 6 and Figure 7 As shown, the integrated hydraulic cylinder structure 5 is located at the lower part of the back of the frame 1. The integrated hydraulic cylinder structure 5 includes a pair of hydraulic cylinder bodies 53 arranged on the frame 1. The pair of hydraulic cylinder bodies 53 are connected by an oil passage 54. One of the hydraulic cylinder bodies 53 is equipped with an adjuster 6. The upper part of one hydraulic cylinder body 53 is connected to a left foot pedal 3, and the upper part of the other hydraulic cylinder body 53 is connected to a right foot pedal 4. This method can also make the left foot pedal 3 and the right foot pedal 4 move back and forth alternately. This overcomes the problem of poor resistance effect of traditional foot pedals with pull ropes (steel wire rope or steel wire, etc.). Moreover, the resistance can be easily adjusted according to individual needs through the adjuster 6, which is more conducive to meeting the user's needs. The cylinder body 53 includes a cylinder body 531. An adjusting seat 532 is provided at one end of the cylinder body 531, and a sealing sleeve 533 is provided at the other end. A reciprocating plunger rod 534 is provided inside the cylinder body 531. A plunger is provided at one end of the plunger rod 534 inside the cylinder body 531, and a connecting seat 535 is provided at the other end of the plunger rod 534. The interior of the cylinder body 531 between the plunger and the adjusting seat 532 is filled with a medium (hydraulic oil). A connecting head 536 for connecting the oil circuit 54 is provided on the adjusting seat 532. This facilitates the extrusion of the medium in one cylinder body 531 through the oil circuit 54 to the other cylinder body 531 when the plunger rod 534 moves downward. This allows the left foot pedal 3 and the right foot pedal 4 to move back and forth alternately. Furthermore, an adjusting valve 6 is provided on the adjusting seat 532 in one cylinder body 53, which facilitates manual adjustment of the oil circuit size, making the operation easier and simpler.
[0038] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the left footrest 3 and the right footrest 4 both include sliders arranged on the frame 1. The sliders move back and forth along the frame 1. Pedals are arranged on the sliders. The sliders are connected to the combined cylinder structure 5 through connecting rods. This kind of setting is simple, easy to implement, and also beneficial to the back-and-forth movement of the pedals.
[0039] Embodiment 5: It can be described based on Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4. As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, the frame 1 includes a main frame 11 and a support frame 12. The upper parts of the main frame 11 and the support frame 12 are movably connected, which is beneficial for unfolding and folding. In this embodiment, unfolding and folding are carried out through a movable shaft, and on the main frame 11 and the support frame 12, they are positioned and fixed by a positioning shaft and a positioning groove when unfolding (they are separated from each other when folding). The left footrest 3 and the right footrest 4 that slide back and forth along the main frame 11 are arranged on the main frame 11. A combined cylinder structure 5 is arranged on the back of the main frame 11. A fixed armrest frame 2 is arranged on the end face of the support frame 12. In this embodiment, the main frame 11 and the support frame 12 form a "person" or "entrance" shape. This kind of setting is reasonable, the structure is simple, and it is also easy to implement.
[0040] In this utility model, the use of the combined cylinder structure 5 ends the relatively cumbersome component structure in the tradition, which is convenient for reducing the difficulty of production and manufacturing, and is also beneficial for reducing the cost investment. At the same time, it not only ends the problem that the resistance effect of the traditional transmission of the footrest by a pull rope (steel wire rope or steel wire, etc.) is not good, but also can easily adjust the resistance size according to personal needs, which is more beneficial for meeting the user's usage requirements.
[0041] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts and rivets that are mature in the existing technology, and no specific description will be made here.
[0042] It should be noted that although the above embodiments have been described in this article, the patent protection scope of this utility model is not limited thereby. Therefore, based on the innovative concept of this utility model, the changes and modifications made to the embodiments described in this article, or the equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of this utility model.
