Description

Technical Field

[0001] This utility model relates to the field of ladder climbing machine technology, and in particular to a positioning and guiding structure for simulating a ladder climbing machine. Background Technology

[0002] As living standards improve, people are paying more and more attention to their health and often strengthen their physical training to improve their physical fitness, such as climbing, mountain climbing, and running. Climbing and mountain climbing are popular because they can enhance cardiopulmonary function, improve musculoskeletal health, enhance nervous system function, and promote digestive health. However, mountain climbing can only be done outdoors, and office workers cannot do this training due to space and time constraints. To solve this problem, various fitness equipment that simulates mountain climbing has appeared on the market, allowing people to train at home.

[0003] For example, the Chinese utility model patent CN220714758U, entitled "A Climbing Training Machine with Resistance Device," includes a frame. The frame includes a main body component, a resistance component, and a linkage component. The resistance component includes an elastic rope, a left main wheel, a right main wheel, a reversing wheel, and a transition piece. One end of the elastic rope is connected to the left main wheel, and the other end of the elastic rope passes through the transition piece and the reversing wheel and is connected to the right main wheel. The reversing wheel is located above the transition piece. The left and right main wheels are respectively located on both sides of the transition piece. The transition piece consists of a housing and four transition wheels assembled inside it.

[0004] In the above scheme, the four transition wheels of the transition component serve to change direction and guide the movement direction of the elastic rope. Under the action of the linkage component, the elastic rope deforms under the force and slides on the four transition wheels, generating friction. It is also subjected to the reverse tension of the four transition wheels, which keeps the elastic rope in full tension for a long time, resulting in a shortened lifespan of the elastic rope. Utility Model Content

[0005] This invention addresses the problem that during the use of a climbing training machine, the elastic rope deforms, slides on the four transition wheels, and generates friction, while also being subjected to the reverse tension of the four transition wheels, resulting in a short lifespan for the elastic rope. The technical problem to be solved by this invention is to provide a positioning and guiding structure for simulating a climbing machine.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: It includes a left foot pedal and a right foot pedal respectively slidably disposed on the left and right sides of the ladder machine frame, and a linkage assembly fixed on the ladder machine frame to link the left and right foot pedals.

The first elastic rope is fixed at the bottom of the ladder machine frame. One end of the second elastic rope is fixed to the right foot pedal, and the other end passes through the left positioning guide wheel assembly and is fixed to the bottom of the ladder machine frame. When the left foot pedal moves up and down, the second elastic rope is always limited to the left positioning guide wheel assembly, and the left positioning guide wheel assembly reduces the tension on the second elastic rope as the left pedal moves up and down. When the right foot pedal moves up and down, the first elastic rope is always limited to the right positioning guide wheel assembly, and the right positioning guide wheel assembly reduces the tension on the first elastic rope as the right pedal moves up and down.

[0011] A further preferred embodiment of this utility model is: both the left positioning guide wheel group and the right positioning guide wheel group are composed of two positioning guide wheels arranged vertically, and the annular groove in the middle of the two positioning guide wheels forms a guide positioning groove for the first elastic rope or the second elastic rope to pass through and guide the movement direction of the first elastic rope or the second elastic rope.

When the left foot pedal moves up and down, the second elastic rope is always limited to the left foot pedal.

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] This embodiment mainly describes the positioning and guiding structure of the simulated ladder climbing machine, as detailed below:

[0027] like Figures 1 to 5As shown, the ladder climbing machine has a ladder climbing machine frame 1 for mounting the left foot pedal 2 and the right foot pedal 3. A positioning and guiding structure simulating the ladder climbing machine is mounted on the ladder climbing machine frame 1. This positioning and guiding structure includes the left foot pedal 2, the right foot pedal 3, a linkage component 4, a first elastic rope 5, and a second elastic rope 6. The left foot pedal 2 and the right foot pedal 3 are slidably mounted on the left and right sides of the ladder climbing machine frame 1, respectively. The linkage component 4 is fixed to the ladder climbing machine frame 1 and links the left foot pedal 2 and the right foot pedal. The linkage component 4 ensures that when one of the left foot pedal 2 or the right foot pedal 3 slides downwards under pressure, the other slides upwards under the influence of the linkage component 4. Left and right foot pedals 2 and 3 are respectively fixedly connected to opposite sides of the frame. The left and right positioning guide wheel groups are 7 and 8, respectively. One end of the first elastic rope 5 is fixed to the left foot pedal 2, and the other end passes through the right positioning guide wheel group 8 and is fixed to the bottom of the ladder machine frame 1. One end of the second elastic rope 6 is fixed to the right foot pedal 3, and the other end passes through the left positioning guide wheel group 7 and is fixed to the bottom of the ladder machine frame 1. When the left foot pedal 2 moves up and down, the second elastic rope 6 is always limited to the left positioning guide wheel group 7, and the left positioning guide wheel group 7 reduces the tension on the second elastic rope 6 as the left pedal moves up and down. When the right foot pedal 3 moves up and down, the first elastic rope 5 is always limited to the right positioning guide wheel group 8, and the right positioning guide wheel group 8 reduces the tension on the first elastic rope 5 as the right pedal moves up and down. The tension on the first elastic rope 5 and the second elastic rope 6 is relatively small, and the friction received by the first elastic rope 5 and the second elastic rope 6 is also reduced, thereby extending the service life of the first elastic rope 5 and the second elastic rope 6. At the same time, the left guide wheel group moves up and down with the left pedal, and the right guide wheel group moves up and down with the right pedal, which provides a certain support for the first elastic rope 5 and the second elastic rope 6, thereby enhancing the stability of the ladder climbing machine and improving the user experience.

[0028] Specifically, a left mounting plate 21 and a right mounting plate 31 are fixed to opposite sides of the left foot pedal 2 and right foot pedal 3, respectively. A left positioning guide wheel assembly 7 is fixed to the upper surface of the left mounting plate 21, and a right positioning guide wheel assembly 8 is fixed to the lower surface of the mounting plate. A fixing plate 122 is provided at the bottom of the ladder machine frame 1. The distance from the fixing plate 122 to the left mounting plate 21 and the right mounting plate 31 is equal. The upper end of the first elastic rope 5 is fixedly connected to the lower surface of the left mounting plate 21, and the lower end passes through the right positioning guide wheel assembly 8 on the lower surface of the right fixing plate 122 before being fixedly connected to the lower surface of the fixing plate 122, ensuring that the first elastic rope 5 is always located below the left and right fixing plates 122. The upper end of the second elastic rope 6 is fixedly connected to the upper surface of the right mounting plate 31, and the lower end passes through the left positioning guide wheel on the upper surface of the left fixing plate 122. Group 7 is fixedly connected to the upper surface of the fixing plate 122, ensuring that the second elastic rope 6 is always located below the left and right fixing plates 122. Since the first elastic rope 5 and the second elastic rope 6 are located below and above the fixing plates 122 and 122 respectively, there is a gap between them. When the left foot pedal 2 and the right foot pedal 3 slide up and down along the ladder machine frame 1, the first elastic rope 5 and the second elastic rope 6 will not contact each other, thus avoiding friction and shortening their service life. The equal distances from the fixing plate 122 to the left mounting plate 21 and the right mounting plate 31 ensure that the pulling force of the left foot pedal 2 on the right foot pedal and the pulling force of the right foot pedal 3 on the left foot pedal 2 are equal, enhancing the stability of the ladder machine structure and improving the user experience.

[0029] like Figure 5 As shown, both the left mounting plate 21 and the right mounting plate 31 are provided with mounting holes 32. The height of the mounting holes 32 is higher than the height of the left positioning guide wheel assembly 7 and the right positioning guide wheel assembly 8. The mounting holes 32 are used to install the first elastic rope 5 and the second elastic rope 6. In order to ensure that the force is equal when the left foot pedal 2 and the right foot pedal 3 are at the same height, the two mounting holes 32 are at the same height. Figure 4As shown, the fixing plate 122 is provided with a connecting hole 123. Bolts 9 are provided in both the connecting hole 123 and the two mounting holes 32. Both ends of the first elastic rope 5 and the second elastic rope 6 are provided with collars. The upper end of the first elastic rope 5 is fitted onto the bolt 9 on the left mounting plate 21 through the collar, and the collar is pressed with a nut to fix the first elastic rope 5 to the left foot pedal 2. The upper end of the second elastic rope 6 is fitted onto the bolt 9 on the right mounting plate 31 through the collar, and the collar is pressed with a nut to fix the second elastic rope 6 to the bolt 9 on the right foot pedal 3. The lower ends of the first elastic rope 5 and the second elastic rope 6 are fitted onto the bolt 9 at the connecting hole 123 through the collar, and are pressed with a nut to fix them to the fixing plate 122. The collar at the lower end of the first elastic rope 5 is located on the lower side of the fixing plate 122, and the collar at the lower end of the second elastic rope 6 is located on the upper side of the fixing plate 122. The connection method of the first elastic rope 5 and the second elastic rope 6 allows for quick installation and replacement of the first elastic rope 5 and the second elastic rope 6. After the first elastic rope 5 and the second elastic rope 6 have been used for a period of time, they may become damaged due to long-term friction with the left positioning guide wheel assembly 7 and the right positioning guide wheel assembly 8, or lose their elasticity due to long-term and frequent stretching. The nuts on the left mounting plate 21, the right mounting plate 31, and the fixing plate 122 can be removed, and the first elastic rope 5 and the second elastic rope 6 can be removed and replaced with new elastic ropes. Installation and disassembly are simple and quick.

[0030] like Figure 2 and Figure 4 As shown, both the left positioning guide wheel group 7 and the right positioning guide wheel group 8 are composed of two positioning guide wheels arranged vertically. The annular groove in the middle of the two positioning guide wheels forms a guide positioning groove for the first elastic rope 5 or the second elastic rope 6 to pass through and guide the movement direction of the first elastic rope 5 or the second elastic rope 6. During use, the first elastic rope 5 and the second elastic rope 6 are both in their respective guide positioning grooves, and the first elastic rope 5 and the second elastic rope 6 slide along their respective guide positioning grooves.

[0031] Specifically, to prevent the first elastic rope 5 from detaching from the right positioning guide wheel group 8 and the second elastic rope 6 from detaching from the left positioning guide wheel group 7 during the use of the ladder climbing machine, the distance between the two positioning guide wheels is less than the diameter of the first elastic rope 5 and the second elastic rope 6.

[0032] Specifically, in order to ensure that the left foot pedal 2 and the right foot pedal 3 are subjected to balanced forces, further enhance the stability of the ladder climbing machine, and improve the user experience, the length of the first elastic rope 5 is equal to the length of the second elastic rope 6.

[0033] like Figure 4 and Figure 5As shown, the linkage component 4 includes a steering wheel 41 and a pull rope 42 fitted on the steering wheel 41. The steering wheel 41 is fixed on the ladder machine frame 1 and is higher than the installation height of the left foot pedal 2 and the right foot pedal 3. One end of the pull rope 42 is fixedly connected to the side of the left foot pedal 2 away from the left positioning steering wheel 41 group, and the other end is fixedly connected to the side of the right positioning steering wheel 41 group of the right foot pedal 3. When the left foot pedal 2 slides down along the ladder machine frame 1, it drives the pull rope 42 to slide down. The other end of the pull rope 42 drives the right foot pedal 3 to slide up along the ladder machine frame 1. When the right foot pedal 3 slides down along the ladder machine frame 1, the pull rope 42 drives the left foot pedal 2 to slide up along the ladder machine frame 1.

[0034] Specifically, to prevent the pull rope 42 from detaching from the steering wheel 41 during sliding, a limiting rod 43 is fixed above the steering wheel 41 on the frame 1 of the climbing machine. The distance between the limiting rod 43 and the steering wheel 41 is smaller than the diameter of the pull rope 42.

[0035] like Figure 1 and Figure 2 As shown, the ladder machine frame 1 includes a handrail frame 11 and a ladder frame 12 that are inclined to the ground. The upper end of the ladder frame 12 is fixed to the handrail frame 11 and forms a "human" shape with the handrail frame 11. The ladder frame 12 has support rods 121 that are inclined to the ground and parallel to each other. The left foot pedal 2 and the right foot pedal 3 are slidably mounted on the two support rods 121 respectively. There are two steering wheels 41, which are symmetrically mounted on the two support rods 121. The fixing plate 122 is fixed to the bottom of the ladder frame 12.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas.
