Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of treadmills, and particularly relates to a multifunctional treadmill. BACKGROUND

[0002] A treadmill is a kind of fitness equipment. The treadmill can enable a person to repeatedly climb stairs, thereby enhancing the function of the cardiovascular system and fully exercising the muscles of the thighs and lower legs.

[0003] The existing treadmills have simple structures, can only realize stepping movement, and cannot realize other functions, thereby causing the problem of single function of the treadmills. UTILITY MODEL CONTENTS

[0004] The utility model provides a multifunctional treadmill, and aims at solving the problem of single function of the treadmills in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the technical scheme that:

[0006] A multifunctional treadmill, comprising a base and a stepping assembly arranged on the base.

[0007] The stepping assembly is rotationally connected to the base, and a locking assembly is arranged between the stepping assembly and the base.

[0008] In the non-rotation mode, the locking assembly locks the stepping assembly to the base; and in the rotation mode, the stepping assembly rotates relative to the base under the driving of the locking assembly when the stepping assembly works.

[0009] Further improved scheme: the stepping assembly is provided with a rotating shaft, and the stepping assembly is rotationally arranged on the base through the rotating shaft.

[0010] Based on the above technical scheme: the base serves as the supporting structure of the whole treadmill and has sufficient stability and bearing capacity; the base is provided with an axle hole matched with the rotating shaft of the stepping assembly, so that the stepping assembly can rotate smoothly and smoothly.

[0011] Further improved scheme: the base is provided with an axle hole matched with the rotating shaft, a rolling bearing is arranged between the rotating shaft and the axle hole, the outer ring of the rolling bearing is in interference fit with the axle hole, and the inner ring of the rolling bearing is in interference fit with the rotating shaft.

[0012] Based on the above technical scheme: the rolling bearing transmits force and motion through the rolling of rolling elements, and the rolling friction has smaller resistance than sliding friction, so that the friction resistance of the rotating shaft during rotation can be reduced and the rotating efficiency can be improved. The rolling bearing can bear a large radial load and a certain axial load, which is important for the stability of the treadmill when bearing the weight of the user and performing high-intensity exercise. The structure of the rolling bearing is compact and simple to lubricate, and the oil consumption is small, so the maintenance is convenient. At the same time, due to its high carrying capacity and small friction resistance, it helps to reduce wear and prolong the service life.

[0013] Further improved scheme: the locking assembly includes a swing arm, a lower connecting seat is arranged on the base and is rotationally connected to the base, and the swing arm is rotationally connected to the lower connecting seat through a shaft body; a connecting pin is arranged on the swing arm, and a first pin hole matched with the connecting pin is arranged on the rotating shaft; an upper connecting seat is arranged on the stepping assembly, and the upper connecting seat is rotationally connected to the stepping assembly; a second pin hole is arranged on the upper connecting seat, and in the rotating mode, the connecting pin is rotationally connected in the second pin hole, and in the non-rotating mode, the connecting pin is inserted in the first pin hole.

[0014] Based on the above technical scheme: when the user exercises, the locking assembly can be adjusted to the rotating mode. In this mode, the connecting pin cooperates with the second pin hole on the upper connecting seat to allow the stepping assembly to rotate relative to the base by a certain angle, thereby realizing the exercise action. This design enables the user to experience a more smooth and natural stepping feeling during exercise. When the user wants to perform other forms of exercise and needs to fix the stepping assembly relative to the base, the locking assembly can be adjusted to the non-rotating mode. In this mode, the connecting pin cooperates with the first pin hole on the rotating shaft to firmly lock the stepping assembly on the base, preventing it from rotating. This design provides a more stable and safe exercise environment for the user.

[0015] The swing arm is rotationally connected to the lower connecting seat through the shaft body, which enables the swing arm to rotate flexibly around the shaft body, thereby realizing the switching of the connecting pin between different pin holes. At the same time, the lower connecting seat serves as a support structure for the swing arm and has sufficient strength and stability to ensure the reliability of the swing arm during rotation. The cooperation of the second pin hole on the upper connecting seat and the connecting pin ensures the stability and safety of the stepping assembly in the rotating mode.

[0016] Further improved scheme: the rotating shaft is fixed with a locking disc, the diameter of the locking disc is greater than the diameter of the rotating shaft, and the first pin hole is arranged on the locking disc.

[0017] Based on the above technical solution: the diameter of the locking disc is larger than the diameter of the rotating shaft, which allows the locking disc to provide a larger contact area and stronger locking force. When the connecting pin is matched with the pin hole on the locking disc, the locking force is distributed more evenly due to the increase in contact area, thereby enhancing the stability of the locking. The locking disc, as an additional component on the rotating shaft, not only increases the diameter of the rotating shaft but also improves the strength of the entire structure. When subjected to heavy loads or high-intensity exercise, the locking disc can withstand greater stress and deformation, thereby protecting the rotating shaft and the stepping assembly from damage. This design prolongs the service life of the multifunctional treadmill and improves its overall reliability and durability.

[0018] Further improved scheme: the base is also fixed with an auxiliary positioning disc, and the auxiliary positioning disc is provided with an auxiliary positioning hole. In the non-rotation mode, the connecting pin passes through the pin hole and the auxiliary positioning hole in sequence.

[0019] Based on the above technical solution: the auxiliary positioning disc, as an additional component on the base, can share the stress generated during the locking of the connecting pin. This helps to reduce the wear and deformation of components such as the connecting pin and the rotating shaft, improving the strength and durability of the entire structure. The cooperation of the auxiliary positioning hole and the connecting pin enhances the reliability of the locking between the stepping assembly and the base. Even during high-intensity exercise or long-term use, the stepping assembly can maintain a stable locking state and is less likely to loosen or fall off.

[0020] Further improved scheme: a lower plain bearing is arranged between the lower connecting seat and the base.

[0021] An upper plain bearing is arranged between the upper connecting seat and the stepping assembly.

[0022] Based on the above technical solution: the plain bearing can significantly reduce the frictional resistance during rotation, allowing the stepping assembly to rotate more smoothly and stably in the non-rotation mode. This helps to improve the user's exercise experience and reduce noise and wear caused by friction. The plain bearing has high rotation accuracy, which can ensure that the stepping assembly maintains a stable trajectory and angle during movement. This helps users maintain the correct posture and movements during exercise, improving the exercise effect.

[0023] The further improved scheme is characterized in that the lower connecting seat is provided with a lower mounting plate, the lower mounting plate has two pieces, a lower mounting space is formed between the two pieces of the lower mounting plate, a part of the swing arm is located in the lower mounting space, and holes matched with the shaft body are formed in the lower mounting plate.

[0024] Based on the above technical scheme: the lower mounting plate and the upper mounting plate form a lower mounting space and an upper mounting space respectively, and provide stable support for the swing arm. This design helps to prevent the swing arm from shaking or deviating during rotation, ensuring the stability and reliability of the locking assembly. By placing a part of the swing arm in the lower mounting space and the upper mounting space, the stress generated during rotation can be more effectively dispersed. This helps to reduce the wear and deformation of components such as the connecting seat, swing arm and shaft body, and improves the strength and durability of the entire structure.

[0025] The further improved scheme is characterized in that the step assembly comprises a swing frame arranged on the rotating shaft, and a pedal is arranged on the swing frame.

[0026] Based on the above technical scheme: the design of the swing frame enables the pedal to produce a certain swinging effect during rotation, which provides users with a more diverse and interesting exercise experience. The swinging action not only helps to enhance the strength and coordination of the lower limbs, but also improves the interest and challenge of the exercise.

[0027] The further improved scheme is characterized in that the base is provided with a pull rope at each end, a fixing frame is arranged at each end of the base for fixing the pull rope, and one end of the pull rope is fixed to the fixing frame by a lock.

[0028] Based on the above technical scheme: the design of the rope enables users to perform stretching and contraction movements of the upper limbs while performing step exercises, thereby achieving a full-body exercise effect. This design helps to enhance the strength, flexibility and coordination of the upper limbs, and improves the overall exercise effect. The use of the pull rope also helps users to maintain balance and coordination during exercise. In particular, when performing high-intensity or high-speed stepping, the traction of the pull rope helps users to stabilize their bodies and reduce the risk of falling due to loss of balance.

[0029] The beneficial effects of the present application are as follows:

[0030] The stepping machine in the utility model can reciprocate relative to the base in the rotating mode, and can realize the exercise of twisting the waist while stepping. In the non-rotating mode, the locking assembly locks the stepping assembly on the base, and the stepping assembly cannot rotate relative to the base. Users can adjust the working mode of the stepping machine according to their exercise needs and preferences, and realize the overall exercise effect. In addition, in the rotating mode, the stepping assembly can rotate relative to the base by a certain angle, which simulates a more natural stepping mode, so that users can feel a more real and comfortable stepping experience during the exercise.

[0031] The two modes of the multifunctional stepping machine adapt to the exercise needs and preferences of different users. Whether the user hopes to carry out high-intensity exercise or needs a more comfortable and natural exercise experience, the user can select the mode suitable for himself to meet the needs. The switching of the rotating mode and the non-rotating mode enables the user to carry out alternating exercise in different exercise states, so as to more comprehensively exercise each part of the body. This alternating exercise mode helps to improve the exercise effect and promote the health and physical fitness.

[0032] The design of the locking assembly ensures the stability and safety of the stepping assembly in the two modes. Especially in the rotating mode, the locking assembly can prevent the stepping assembly from rotating too much, thereby avoiding the safety hazards caused by improper operation of the user.
