Description

Technical Field

[0001] The utility model relates to fitness equipment, in particular to a walking machine with an adjustable lifting slope. Background Art

[0002] With the continuous development of fitness equipment technology, as a kind of aerobic exercise equipment widely used in homes and gyms, the functional design of walking machines, especially the importance of slope adjustment systems, has become increasingly prominent. The existing treadmill slope adjustment device, as shown in the Chinese utility model patent application number CN201320886278.4, proposes a design scheme for the lifting and lowering slope adjustment structure of a treadmill.

[0003] However, in actual application, this type of slope adjustment device exposes some key technical and practical problems. First, the slope adjustment device described in the patent is installed at the rear of the treadmill and relies on the cooperation between specific components to lock and maintain the set slope. However, when the user performs dynamic exercise on the treadmill, the continuous vibration generated by the human body movement and the gravity effect of the running belt and the running board itself will produce a non-negligible impact load. In this case, relying solely on the tension of the left and right springs to fix the slope position is obviously not enough to resist the force changes under dynamic conditions. The consequence is that the slope adjustment member is easily disengaged from the preset adjustment slot due to vibration, making it difficult to maintain a stable set value for the slope, which in turn affects the user's exercise experience and safety.

[0004] Secondly, the patented slope adjustment structure adopts a left-right symmetrical distribution and is adjusted synchronously through the linkage of the middle pull rod assembly. However, this linkage mechanism places extremely high demands on the manufacturing accuracy between components, especially on the processing accuracy of the slideway of the adjustment plate. It is found in actual production that if the slideway and related components are too loose, it may cause the overall structure to loosen, and the slope adjustment on the left and right sides will be unbalanced, further aggravating the unstable state during the movement; if the fit is too tight, the operating resistance will increase, making it difficult to achieve smooth and effective slope adjustment even with the help of the elastic recovery force of the spring.

[0005] In view of the above-mentioned defects, the utility model aims to provide an improved treadmill slope adjustment system, aiming to overcome the problems of poor slope stability, easy disengagement and difficult operation caused by unreasonable structural design and difficulty in precision control in the prior art, so as to achieve a more reliable, stable and easy-to-use treadmill slope adjustment function. Utility Model Content

[0006] The utility model aims to solve the above problems in the prior art and provides a walking machine with adjustable lifting slope.

[0007] In order to achieve the above application purpose, the utility model adopts the following technical solution: the walking machine for adjusting the lifting slope includes a walking machine main body, and also includes:

[0008] The adjustment plates are arranged at both ends of the front end of the walking machine body in the width direction, and the two adjustment plates are rotatably connected to the walking machine body through a rotating shaft, and a plurality of adjustment holes are evenly spaced with the rotating shaft as the center;

[0009] A caster wheel is arranged at one end of the adjustment plate away from the rotating shaft and can contact the ground;

[0010] A quick-release pin is used to be inserted into any of the adjustment holes and into a positioning hole reserved on the walking machine body to adjust the rotation angle of the adjustment plate, thereby adjusting the slope of the walking machine body;

[0011] The lines connecting the centers of the quick-release pin, the rotating shaft and the caster form a triangle.

[0012] Working principle and beneficial effects: Compared with the prior art, the present application utilizes rotating the adjustment plate, inserting the quick-release pin into the corresponding adjustment hole and then fixing it with the positioning hole reserved on the treadmill body to achieve rotation adjustment of the adjustment plate. When the caster of the adjustment plate contacts the ground, the front end of the treadmill body will be tilted, thereby achieving the slope adjustment of the treadmill body. In addition, since the line connecting the centers of the quick-release pin, the rotating shaft and the caster forms a triangle, it means that the supporting strength is higher than the prior art, and it has a good stability effect.

[0013] Furthermore, when the quick-release pin is located at the lowest adjustment hole, the line connecting the center of the quick-release pin and the center of the rotating shaft and the line connecting the center of the rotating shaft and the center of the caster have an angle. The triangle stability principle in mechanics is fully utilized, that is, the line connecting the centers of the quick-release pin, the rotating shaft and the caster forms a triangle structure. This structural design ensures that during the slope adjustment process, no matter what angle the walking machine is at, it can obtain higher support rigidity and stability, effectively preventing the problem of slope adjustment instability caused by vibration or uneven force, and greatly improving the safety and comfort of the product in actual use.

[0014] Furthermore, the angle is 0 to 5 degrees. As walking machine products, the industry has certain restrictions on packaging size and height. When designing this slope adjustment, the height of the packaging box needs to be considered, and the minimum angle is set within this range to maximize the use of the packaging box.

[0015] Furthermore, the rotating shaft is located at the bottom of the side tube of the walking machine body. The triangular structure can be used more effectively, because when adjusting the slope, it is completely effective to lengthen the distance between the wheel and the rotating fulcrum. If the gear adjustment plate is lengthened, the stability is not enough. Therefore, when the rotating shaft is located at the bottom of the walking machine body, it has a good effect even if it is short, and the short stability is very good. At the same time, the same rotating shaft at the bottom will adjust the slope to the maximum state, which is more reasonable.

[0016] Furthermore, the number of the adjustment holes is 3 to 6. The number of the adjustment holes is designed to be between 3 and 6, which not only takes into account the functionality, accuracy and stability of the slope adjustment of the walking machine, but also takes into account the practicality and economy of the product.

[0017] Furthermore, the number of the adjustment holes is 6.

[0018] Furthermore, the angle difference between the two adjustment holes is 12 to 16 degrees. Such an angle interval setting enables the slope adjustment to achieve a relatively fine gradient change. The user can gradually adjust the slope of the walking machine according to their own needs and exercise plans, which is conducive to achieving a more stable and progressive physical training and avoiding excessive load on the body caused by sudden changes in slope.

[0019] Furthermore, one or more pull rings are provided on the quick release pin to facilitate pulling out the quick release pin.

[0020] Furthermore, a washer is provided on the rotating shaft, and the washer is located between the side of the walking machine body and the adjustment plate, so that there is a gap between the side of the walking machine body and the adjustment plate. The washer can play a role of buffering and isolation during the mutual rotation of the walking machine body and the adjustment plate, reduce the friction and wear caused by the direct contact between the two, and extend the service life of the equipment.

[0021] Furthermore, the quick release pin is made of stainless steel, which has the following effects:

[0022] Corrosion resistance: Stainless steel has excellent corrosion resistance and can be used for a long time in a humid, sweaty, detergent environment without rusting. It is especially suitable for fitness equipment, which is often exposed to human sweat and may be cleaned by detergents.

[0023] High strength: Stainless steel has high mechanical strength and hardness, which can ensure that the quick release pin is not easily deformed or broken when subjected to large pressure and dynamic loads, ensuring the stability and durability of the slope adjustment function.

[0024] Good wear resistance: Stainless steel has excellent wear resistance and is durable. Even during repeated plugging and unplugging and use, it is not easy to wear and maintain a good fit, ensuring that each lock is firm and reliable.

[0025] Hygiene and safety: Stainless steel is non-toxic, odorless, and pollution-free, meeting health and safety standards. It is particularly suitable for products that come into contact with the human body, reducing potential allergic risks and the possibility of chemical reactions.

[0026] Aesthetics: The surface of stainless steel is smooth and bright, easy to clean and maintain, and has good visual effects, which can enhance the appearance texture and grade of the entire treadmill. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0033] like Figure 1-3 As shown, the utility model relates to a walking machine for adjusting the lifting slope, which mainly comprises a walking machine body 1 and a series of innovative structures. The specific structure and working principle are as follows:

[0034] An adjustment plate 2 is disposed at each of the two ends in the width direction of the front end of the walking machine body 1, and the two adjustment plates 2 are rotatably connected to the walking machine body 1 through a rotating shaft 3. It is worth noting that a plurality of adjustment holes 21 are evenly arranged along the center of the rotating shaft 3, and the number is preferably 6, to ensure the accuracy and diversity of the slope adjustment.

[0035] Preferably, the rotating shaft 3 includes a bolt 31 and a nut. The part connected to the walking machine body 1 is not shown in the figure. In fact, the bolt 31 is first installed in the hole of the frame of the walking machine body 1, and then locked with a nut, which does not affect the rotation of the adjustment plate 2. The nut is preferably a locking nut 32. The walking machine body 1 is provided with a positioning hole 11 for inserting a pin.

[0036] A caster 4 is provided at one end of the adjustment plate 2 away from the rotating shaft 3. When the slope is adjusted, the caster 4 can contact the ground to support and adjust the lifting angle of the front end of the walking machine body 1. According to the mechanical triangle stability principle, the quick release pin 5, the rotating shaft 3 and the center line of the caster 4 form a stable triangle structure, thereby ensuring that the walking machine can maintain good support rigidity and stability at any slope. In particular, when the quick release pin 5 is located in the adjustment hole 21 with the minimum angle, the angle between the center of the circle and the center of the rotating shaft 3 and the center of the rotating shaft 3 and the center of the caster 4 is controlled within the range of 0 to 5°. This design not only meets the product's packaging size and height restrictions, but also ensures the flexibility of slope adjustment.

[0037] In order to reduce the service life of the walking machine body 1 and the adjustment plate 2 due to friction and wear during the rotation process, a washer 6 is also installed on the rotating shaft 3. The washer 6 is located exactly between the side of the walking machine body 1 and the adjustment plate 2, forming a certain gap to play a buffering and isolating role.

[0038] The rotating shaft 3 is located at the bottom of the side tube of the walking machine body 1. This layout design can maximize the advantages of the triangular support structure, and can achieve efficient slope adjustment even in a limited space, while ensuring the stability of the device. The side tube is part of the frame of the walking machine body 1 and belongs to the prior art.

[0039] One or more pull rings 51 are provided on the quick release pin 5, so that the user can easily pull out and insert the quick release pin 5 to conveniently adjust the slope. The angle difference between the adjustment holes 21 is set to 12-16 degrees. The slope changes in this range are delicate. The user can gradually adjust the slope of the walking machine according to personal physique and exercise plan, so as to achieve smooth and gradual physical training and effectively avoid discomfort and burden caused by sudden changes in slope to the human body.

[0040] Among them, the quick release pin 5 is an existing mature product, that is, a positioning pin with a ring and a steel ball, which can be directly purchased.

[0041] The quick release pin 5 is made of stainless steel, which has the following advantages: first, it has excellent corrosion resistance, and is particularly suitable for the use environment of fitness equipment. It can remain rust-free for a long time even under the influence of sweat, moisture or detergents; second, it has high mechanical strength and hardness, ensuring that the shape remains unchanged when subjected to high pressure and dynamic loads, and ensuring the stability of the slope adjustment function; third, it has good wear resistance, so that the quick release pin 5 is not easy to wear during repeated insertion and use, and maintains a good fit; fourth, the non-toxic, odorless and pollution-free characteristics of stainless steel meet health and safety standards, and reduce the risk of allergies and the possibility of chemical reactions when in contact with the human body; fifth, the surface of stainless steel is smooth and bright, easy to clean and maintain, and at the same time improves the overall aesthetics and texture of the treadmill.

[0042] The above is the specific structure and working principle of a walking machine for adjusting the lifting slope of the utility model. Through the above design, the utility model successfully solves the problem of poor slope adjustment stability in the prior art, while taking into account the functionality, accuracy, practicality and economic benefits of the equipment, and significantly improving the safety and comfort of the walking machine.

[0043] The parts not described in detail in the present invention are prior art, so the present invention does not describe them in detail.

[0044] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0045] Although this article uses more terms such as walking machine body 1, adjustment plate 2, shaft 3, caster 4, quick release pin 5, washer 6, positioning hole 11, adjustment hole 21, bolt 31, lock nut 32, pull ring 51, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0046] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present utility model fall within the protection scope of the present utility model.
