Technical Field

[0001] The utility model relates to the technical field of walking machines, in particular to a columnless walking machine. Background Art

[0002] A walking machine or a treadmill is a common fitness equipment in people's daily life. It is a kind of equipment for exercising walking or running. In order to increase the exercise intensity, people want to improve their exercise intensity. Without handrails, the speed of the walking machine can only be limited within 6 km / h. With the function of handrails, the speed limit can be increased, thereby increasing the exercise intensity.

[0003] The inventors of this application found the following problems in the practical use process:

[0004] The current columnless walking machine cancels the front column of the walking machine, enabling users to experience a greater sense of space when walking. However, during use, the lack of a front column results in nowhere to place the handrails, and users may fall due to lack of support when using it.

[0005] Therefore, it is necessary to provide a columnless walking machine to solve the above technical problems. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is that the lack of a front column leads to nowhere to place the handrails, and users may fall due to lack of support when using it. In view of the above defects of the prior art, a columnless walking machine is provided.

[0007] To achieve the above object, the technical solution of the utility model is: a columnless walking machine, including a walking machine, lifting handrail mechanisms are arranged on both sides of the walking machine. The lifting handrail mechanism includes a mounting frame, a motor is fixedly connected to the top of the mounting frame, a worm is fixedly connected to the output end of the motor, a worm gear is meshed on one side of the worm, a first rotation groove is formed in the worm gear, and a first connecting rod is rotatably connected to the inside of the first rotation groove;

[0008] A first rotation block is arranged above the worm gear, a second rotation groove is formed in the first rotation block, and a second connecting rod is rotatably connected to the inside of the second rotation groove through a torsion rotating shaft;

[0009] An inclined plane block is arranged above the first rotation block for making the first connecting rod form a certain angle with the horizontal plane.

[0010] By adopting the above technical solution, with the use of the inclined plane block, the lifting armrest mechanism can move a certain distance to both sides after rising, leaving more sufficient activity space for hands and the like. While the columnless treadmill retains a spacious exercise space, it can also provide necessary armrest support according to the needs of users. Especially for those users who need extra support to maintain balance, the stability and safety of using the treadmill are enhanced.

[0011] Further setting: There is a third link rotatably connected between one end of the first link and one end of the second link, and a support frame is fixedly connected to the third link.

[0012] By adopting the above technical solution, the link mechanism composed of the first link, the second link and the third link realizes the stable lifting movement of the support frame, ensures that the armrest can remain stable during the lifting process, and enhances the stability and sense of security of the user during use.

[0013] Further setting: An installation groove is formed inside the support frame, and a rubber block is fixedly connected inside the installation groove.

[0014] By adopting the above technical solution, the installation groove formed inside the support frame provides a stable installation position for the rubber block, ensuring that the rubber block will not move or fall off during use, thus maintaining the comfort and stability of the armrest.

[0015] Further setting: Triangular protrusions are provided on both inner walls of the rubber block.

[0016] By adopting the above technical solution, the triangular protrusions provided on both inner walls of the rubber block provide a stable clamping structure for the sliding rod. When the sliding rod is pulled to a suitable position, the triangular protrusions can effectively clamp the triangular grooves on both sides of the sliding rod to prevent it from accidentally sliding during use.

[0017] Further setting: A sliding rod is slidably connected inside the rubber block, and triangular grooves cooperating with the triangular protrusions are formed on both sides of the bottom of the sliding rod.

[0018] By adopting the above technical solution, the sliding rod slidably connected inside the rubber block provides an adjustable armrest support point for the user. The user can easily slide the sliding rod back and forth according to their own height, arm length or exercise needs to find the most suitable armrest position for themselves.

[0019] Further setting: Rounded corners for preventing cuts are provided at the corners of the sliding rod.

[0020] By adopting the above technical solution, the rounded corners provided at the edges of the sliding rod to prevent cuts enhance the safety of the user during use. The rounded corner design can avoid direct contact between sharp edges and the user's hands or other parts, thereby reducing the potential risk of cuts.

[0021] Further setting, there are two sets of the lifting armrest mechanisms, and the two sets of the lifting armrest mechanisms are arranged in a mirror image structure, and sound absorption holes are provided on the walking machine.

[0022] By adopting the above technical solution, the lifting armrest mechanisms are set to two sets and arranged in a mirror image structure, which provides bilateral armrest support for the user and further enhances the stability and safety of the walking machine.

[0023] Compared with the related technologies, a columnless walking machine provided by the present utility model has the following beneficial effects:

[0024] The present utility model provides a columnless walking machine. By setting the lifting armrest mechanism, the user can easily raise the armrest according to needs when using the walking machine, thereby enjoying the convenience of the armrest, enhancing the stability and safety of using the walking machine. During high-intensity or long-term exercise, the armrest can provide necessary support to reduce the risk of imbalance or falling. When the lifting armrest mechanism raises the armrest, the second connecting rod rotates outward around the torsion rotating shaft under the guidance of the inclined plane block during rotation, so that while providing armrest support, a larger space can be formed on both sides of the walking machine, which not only meets the user's need for armrest support but also further improves the comfort of use, enabling the user to move more freely during exercise without being restricted by the position of the armrest, and enhancing the user experience and practicality of the walking machine.

[0025] The present utility model provides a columnless walking machine. By adopting the installation groove, rubber block and triangular protrusions, the sliding rod can stably slide inside the rubber block, providing the user with the function of adjusting the position of the armrest, enhancing the convenience and comfort of use. When the sliding rod is adjusted to a suitable position, the triangular protrusions on the inner wall of the rubber block can firmly hold the triangular grooves on both sides of the sliding rod to ensure that the sliding rod will not accidentally slide or fall off during use, providing stable and reliable armrest support for the user and enhancing the safety and user experience of the walking machine.

Detailed implementation manners

[0032] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant attached drawings. The typical embodiments of the present utility model are shown in the attached drawings.

[0033] Embodiment 1:

[0034] As Figures 1-5 shown, a columnless treadmill of the present utility model includes a treadmill 1, lifting armrest mechanisms 2 are arranged on both sides of the treadmill 1, the lifting armrest mechanism 2 includes a mounting bracket 201, a motor 202 is fixedly connected to the top of the mounting bracket 201, a worm 203 is fixedly connected to the output end of the motor 202, a worm gear 204 is meshed with one side of the worm 203, a first rotation groove 205 is formed in the worm gear 204, and a first connecting rod 206 is rotatably connected to the inside of the first rotation groove 205;

[0035] A first rotating block 207 is arranged above the worm gear 204, a second rotation groove 208 is formed in the first rotating block 207, and a second connecting rod 209 is rotatably connected to the inside of the second rotation groove 208 through a torsion rotating shaft;

[0036] Above the first rotating block 207, there is an inclined plane block 210 for making the first connecting rod 206 form a certain angle with the horizontal plane. By using the inclined plane block 210, the lifting arm mechanism 2 can move a certain distance to both sides after rising, leaving more sufficient space for activities such as hands, etc. While the columnless treadmill retains a spacious exercise space, it can also provide necessary armrest support according to the needs of users. Especially for those users who need extra support to maintain balance, the stability and safety of using the treadmill are enhanced. At the same time, the meshing transmission mode of the worm gear 204 and the worm 203 is applied to the lifting mechanism of the armrest. Due to the self-locking property of this transmission mode, it can keep the position of the armrest stable after rising and will not accidentally drop due to external factors. The design of the connecting rod mechanism, including the first connecting rod 206, the second connecting rod 209 and their connections with the worm gear 204 and the first rotating block 207, realizes the smooth lifting of the armrest, enabling users to easily adjust the height and angle of the armrest according to their own height and usage habits to find the most comfortable exercise posture.

[0037] As Figure 3 and Figure 4 shown, a third connecting rod 211 is rotatably connected between one end of the first connecting rod 206 and one end of the second connecting rod 209. A support frame 212 is fixedly connected to the third connecting rod 211. The connecting rod mechanism composed of the first connecting rod 206, the second connecting rod 209 and the third connecting rod 211 realizes the stable lifting movement of the support frame 212, ensuring that the armrest can remain stable during the lifting process and enhancing the stability and sense of security of the user during use. At the same time, the support frame 212 is fixedly connected to the third connecting rod 211. When the connecting rod mechanism moves, the support frame 212 will rise and fall accordingly, enabling users to easily adjust the height of the support frame 212 according to their own needs to find the most suitable exercise posture.

[0038] As Figure 1 shown, there are two sets of lifting arm mechanisms 2, and the two sets of lifting arm mechanisms 2 are arranged in a mirror image structure. The treadmill 1 is provided with sound collection holes 3. The lifting arm mechanisms 2 are set to two sets and arranged in a mirror image structure, which provides bilateral armrest support for users and further enhances the stability and safety of the treadmill 1. At the same time, the sound collection holes 3 provided on the treadmill 1 provide a convenient voice control function for users. Users can control the lifting of the armrest through simple voice commands without manual operation, improving the convenience of use and the user experience.

[0039] In operation, when using the treadmill 1, a voice command to raise is first issued. The voice is received by the controller through the sound receiving hole 3. The controller starts the motor 202. The motor 202 drives the worm 203 to drive the worm gear 204 to rotate. The worm gear 204 drives the parallelogram linkage mechanism formed by the first link 206, the second link 209, and the third link 211 to rotate, so that the support frame 212 fixed on the third link 211 can rise while maintaining a vertical state. At the same time, the second link 209 is guided by the inclined plane block 210 during rotation and rotates outward around the torsion shaft, so that while providing armrests, a larger space can be formed on both sides, improving the comfort of using the treadmill 1.

[0040] Embodiment 2:

[0041] As Figure 4 and Figure 5 shown, an installation groove 213 is opened inside the support frame 212. A rubber block 214 is fixedly connected inside the installation groove 213. The installation groove 213 opened inside the support frame 212 provides a stable installation position for the rubber block 214, ensuring that the rubber block 214 will not move or fall off during use, thus maintaining the comfort and stability of the armrest. At the same time, the rubber material has good elasticity and anti-slip performance, which can effectively prevent the risk of the sliding rod 215 from sliding, providing a safer and more comfortable exercise experience for users.

[0042] As Figure 4 and Figure 5 shown, triangular protrusions are provided on both inner walls of the rubber block 214. The triangular protrusions provided on both inner walls of the rubber block 214 provide a stable clamping structure for the sliding rod 215. When the sliding rod 215 is pulled to the appropriate position, the triangular protrusions can effectively clamp the triangular grooves on both sides of the sliding rod 215 to prevent it from accidentally sliding during use. At the same time, the design of the triangular protrusions also increases the friction between the rubber block 214 and the sliding rod 215, further enhancing the stability of the armrest.

[0043] As Figure 4 and Figure 5As shown in the figure, a sliding rod 215 is slidably connected inside the rubber block 214. Triangular grooves that cooperate with the triangular protrusions are formed on both sides of the bottom of the sliding rod 215. The sliding rod 215 slidably connected inside the rubber block 214 provides an adjustable handrail support point for the user. The user can easily slide the sliding rod 215 back and forth according to their own height, arm length, or exercise needs to find the most suitable handrail position. At the same time, the triangular grooves formed on both sides of the bottom of the sliding rod 215 that cooperate with the triangular protrusions ensure that the sliding rod 215 can be stably fixed inside the rubber block 214 after being adjusted to the appropriate position, increasing the stability of the handrail and preventing accidental sliding of the sliding rod 215 during use, providing a safer and more reliable exercise environment for the user.

[0044] As Figure 4 shown, rounded corners 216 for preventing cuts are provided at the corners of the sliding rod 215. The rounded corners 216 for preventing cuts provided at the corners of the sliding rod 215 improve the safety of the user during use. The rounded corner design can prevent sharp corners from directly contacting the user's hand or other parts, thereby reducing the potential risk of cuts. At the same time, the rounded corners 216 also make the sliding rod 215 more rounded and beautiful in appearance, improving the overall quality of the non-column walking machine.

[0045] During implementation, when the support frame 212 is raised to a certain height, the user pulls the sliding rod 215 to one side. The sliding rod 215 slides inside the rubber block 214. When it slides to the appropriate position, the triangular protrusions on the inner wall of the rubber block 214 catch the triangular grooves on both sides of the sliding rod 215, enabling the sliding rod 215 to be firmly fixed in the current position and providing appropriate support.

[0046] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0047] 1. The lifting handrail mechanism can open to both sides while rising, providing a larger activity space, thereby increasing the comfort of the user;

[0048] 2. By setting the sliding rod, the user can manually adjust the position of the sliding rod after it is raised to a certain height, providing a better handrail experience.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
