These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concepts of the present invention for those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a structural diagram of a walking machine roller adjustment structure 10 shown in an embodiment of the utility model. Figure 2 yes Figure 1The diagram of an exploded structure of the treadmill roller adjustment structure 10 is shown. Figure 3 yes Figure 1 The treadmill roller adjustment structure 10 is a schematic cross-sectional view taken along position A1-A2. The treadmill roller adjustment structure 10 may include: a corner guard structure 11, a roller assembly 13, a treadmill bracket 14, an adjustment bolt 15, and a clamping assembly 16.

[0043] The corner guard structure 11 can be located on one side of one end of the roller assembly 13 and can have a first through-hole k1. The roller assembly 13 can have a threaded through-hole k5 on one end. The treadmill support 14 can be located on the side of the roller assembly 13 facing away from the corner guard structure 11 and can have a second through-hole k2. The treadmill roller adjustment structure 10 can also include a treadbelt 12, a portion of which can be wound around the roller assembly 13, which can be used to support the treadbelt 12.

[0044] The corner guard 11 can be located at one end of the roller assembly 13, away from the treadmill support 14. The corner guard 11 can protect the end of the roller assembly 13. The first through hole k1 in the corner guard 11 can be a smooth through hole, that is, the inner wall of the first through hole k1 is not threaded. The second through hole k2 in the treadmill support 14 can be a smooth through hole, that is, the inner wall of the second through hole k2 is not threaded.

[0045] The adjusting bolt 15 can be sequentially inserted through the first through-hole k1, the threaded through-hole k5, and the second through-hole k2, with the first end of the adjusting bolt 15 extending out of the second through-hole k2. In other words, the adjusting bolt 15 can be sequentially inserted through the first through-hole k1 of the corner guard 11, the threaded through-hole k5 of the roller assembly 13, and the second through-hole k2 of the treadmill support 14.

[0046] The adjusting bolt 15 may include a first head and a first screw. When installing the adjusting bolt 15, the first screw of the adjusting bolt 15 can be passed through the first through hole k1, the threaded through hole k5 and the second through hole k2 in sequence, and the first head of the adjusting bolt 15 is located outside the first through hole k1 of the corner guard structure 11, wherein the size of the first head of the adjusting bolt 15 is larger than the diameter of the first through hole k1 of the corner guard structure 11, so that the corner guard structure 11 can support the adjusting bolt 15, and it is also convenient for the user to rotate the adjusting bolt 15 through the first head of the adjusting bolt 15 located outside the first through hole k1.

[0047] The threaded through hole k5 of the roller assembly 13 can be threadedly connected to the first screw of the adjustment bolt 15. The first screw can rotate about its central axis to drive the roller assembly 13 to move in the length direction of the first screw, thereby tightening or loosening the treadbelt 12. In this way, during use of the treadmill roller adjustment structure 10, the tightness of the treadbelt 12 can be adjusted by adjusting the bolt 15.

[0048] The clamping assembly 16 can be located on the side of the second through hole k2 away from the threaded through hole k5 and connected to the treadmill bracket 14. Figure 3 and Figure 4 , Figure 4 This is a schematic structural diagram of a clamping assembly 16 and an adjusting bolt 15 provided in an embodiment of the present invention. The clamping assembly 16 may have a limiting groove c1. The first end of the adjusting bolt 15 is located in the limiting groove c1, and the side wall of the first end of the adjusting bolt 15 abuts against the groove wall of the limiting groove c1, so that the clamping assembly 16 clamps the side wall of the first end of the adjusting bolt 15. The first end may be the end of the first screw of the adjusting bolt 15 away from the first head of the adjusting bolt 15. The clamping assembly 16 can be fixedly mounted on the treadmill bracket 14. The clamping assembly 16 can tighten the first end of the adjusting bolt 15 extending out of the second through hole k2. When the treadmill roller adjustment structure 10 is subjected to external vibrations, the adjusting bolt 15 may be at risk of being dislodged. The clamping assembly 16 can provide friction for the adjusting bolt 15 to counteract the force applied when the adjusting bolt 15 is dislodged. In this way, the adjusting bolt 15 can be firmly clamped by the clamping assembly 16 to limit the adjusting bolt 15, thereby preventing the adjusting bolt 15 from loosening when the treadmill roller adjustment structure 10 is subjected to external vibrations or the treadmill bracket 14 is deformed, thereby improving the stability of the adjusting bolt 15.

[0049] Furthermore, the frictional force provided by the clamping assembly 16 to the adjusting bolt 15 by tightening it can be greater than the force applied to the adjusting bolt 15 when it is loosened, and can be less than the force applied by the user to the adjusting bolt 15 when adjusting the position of the roller assembly 13. For example, the user can use a screwdriver or an electric screwdriver to turn the adjusting bolt 15. Thus, because the clamping assembly 16 and the adjusting bolt 15 are not fixedly connected, the user does not need to disassemble the treadmill to separate the clamping assembly 16 and the adjusting bolt 15 when adjusting the tightness of the treadbelt 12. Instead, the user simply applies a force to the adjusting bolt 15 from the outside of the corner guard 11 to turn the adjusting bolt 15. In other words, the clamping assembly 16 securely holds the adjusting bolt 15, improving the stability of the adjusting bolt 15 while also making it easier for the user to adjust the tightness of the treadbelt 12 using the adjusting bolt 15, further enhancing the user experience.

[0050] In summary, the present invention provides a treadmill roller adjustment structure comprising a corner guard structure, a roller assembly, a treadmill support, an adjustment bolt, and a clamping assembly. The roller assembly is threadedly connected to the adjustment bolt via a threaded through-hole. Rotation of the adjustment bolt drives the roller assembly to adjust the tightness of the running belt. Furthermore, the clamping assembly securely clamps the adjustment bolt and limits its position, preventing it from loosening due to external vibrations or deformation of the treadmill support. This improves the stability of the adjustment bolt and enhances the user experience.

[0051] It should be noted that the walking machine roller adjustment structure 10 may include multiple roller assemblies 13. In the embodiment of the utility model, two adjustment bolts 15 are respectively connected to the two ends of a roller assembly 13, and the tightness of the running belt 12 is adjusted by the roller assembly 13 as an example.

[0052] The walking machine roller adjustment structure 10 may include a plurality of corner protection structures 11 , and the plurality of corner protection structures 11 are respectively located at both ends of the plurality of roller assemblies 13 .

[0053] In an exemplary embodiment, the treadmill roller adjustment structure 10 may further include four adjustment bolts 15, two of the four adjustment bolts 15 are respectively connected to the two ends of one roller assembly 13, and the other two adjustment bolts 15 are respectively connected to the two ends of another roller assembly 13, so as to adjust the tightness of the running belt 12 through the two roller assemblies 13. The embodiment of the utility model does not limit the number of adjustment bolts 15 in the treadmill roller adjustment structure 10.

[0054] In an exemplary embodiment, the first screw rotates about its central axis in two ways: a first direction and a second direction. The first direction may be one of a clockwise direction and a counterclockwise direction, and the second direction may be the other of the clockwise direction and the counterclockwise direction.

[0055] When the first screw of the adjusting bolt 15 rotates in a first direction about its central axis, the first screw drives the roller assembly 13 toward the treadmill frame 14, thereby loosening the treadmill belt 12. When the first screw of the adjusting bolt 15 rotates in a second direction about its central axis, the first screw drives the roller assembly 13 away from the treadmill frame 14, thereby tightening the treadmill belt 12. It should be noted that the direction in which the roller assembly 13 moves when the first screw of the adjusting bolt 15 rotates clockwise or counterclockwise about its central axis is determined by the thread rotation direction of the first screw and the thread rotation direction of the threaded through hole k5 in the roller assembly 13.

[0056] It can be understood that the first end of the adjusting bolt 15 refers to the part of the screw rod body of the first screw in the adjusting bolt 15 away from the first head. The first end can have a preset length. Exemplarily, the length of the first end of the adjusting bolt 15 is 2 cm to 5 cm.

[0057] Please refer to Figure 5 and Figure 6 , Figure 5 yes Figure 1 The treadmill roller adjustment structure 10 is a schematic cross-sectional view along the B1-B2 position. Figure 6 This is a schematic diagram of the connection structure of a first clamping plate 161, a second clamping plate 162 and a connecting plate 163 provided in an embodiment of the present invention. In an optional embodiment, the clamping assembly 16 may include a first clamping plate 161, a second clamping plate 162, a connecting plate 163 and a locking structure 164.

[0058] The first clamping plate 161 and the second clamping plate 162 can be respectively located on either side of the first end of the adjusting bolt 15, and the ends of the connecting plate 163 can be respectively connected to the first clamping plate 161 and the second clamping plate 162 to form a limiting groove. The locking structure 164 can be located on the side of the first end of the adjusting bolt 15 facing away from the connecting plate 163, and the locking structure 164 can be respectively connected to the first clamping plate 161 and the second clamping plate 162. The locking structure 164 can apply a force to the first clamping plate 161 toward the second clamping plate 162, or the locking structure 164 can apply a force to the second clamping plate 162 toward the first clamping plate 161, that is, the locking structure 164 can tighten the first clamping plate 161 and the second clamping plate 162 in a direction close to the adjusting bolt 15, so that the first clamping plate 161 and the second clamping plate 162 can clamp the adjusting bolt 15.

[0059] Please refer to Figure 7 , Figure 7This is a schematic diagram of the connection structure of a first clamping plate 161, a second clamping plate 162 and a connecting plate 163 provided in an embodiment of the present utility model. In an optional embodiment, when not locked by the locking structure, one end of the first clamping plate 161 can be fixedly connected to the connecting plate 163, and one end of the second clamping plate 162 can be fixedly connected to the connecting plate 163; the shortest distance d1 between one end of the first clamping plate 161 and one end of the second clamping plate 162 can be less than or equal to the diameter of the first end of the adjusting bolt 15, and the diameter of the first end of the adjusting bolt 15 is less than or equal to the shortest distance d2 between the other end of the first clamping plate 161 and the other end of the second clamping plate 162. In this way, the first clamping plate 161, the second clamping plate 162 and the connecting plate 163 can form a U-shaped clamping structure, that is, the limiting groove formed by the first clamping plate 161, the second clamping plate 162 and the connecting plate 163 can be U-shaped, and the limiting groove has relative notches and groove bottoms. The shortest distance d1 between one end of the first clamping plate 161 and one end of the second clamping plate 162 can be the size of the groove bottom, and the shortest distance d2 between the other end of the first clamping plate 161 and the other end of the second clamping plate 162 can be the size of the notch. The larger size of the notch can reduce the difficulty for the user to extend the first end of the adjusting bolt 15 into the limiting groove of the clamping assembly 16.

[0060] Exemplarily, the shortest distance d1 between one end of the first clamping plate 161 and one end of the second clamping plate 162 is less than or equal to the diameter of the first screw of the adjusting bolt 15, and the shortest distance d2 between the other end of the first clamping plate 161 and the other end of the second clamping plate 162 can be greater than or equal to the diameter of the first screw of the adjusting bolt 15.

[0061] Please refer to Figure 5 and Figure 6 In an alternative embodiment, the first clamping plate 161 may have a third through hole k3, and the second clamping plate 162 may have a fourth through hole k4. The locking structure 164 may include a first bolt 1641 and a fixing member 1642. The fixing member 1642 may be located on a side of the second clamping plate 162 facing away from the first clamping plate 161. The fixing member 1642 has a first mounting hole k6. The first bolt 1641 may be inserted into the third through hole k3 and the fourth through hole k4, and the end of the first bolt 1641 extends into the first mounting hole k6 and is threadedly connected to the fixing member 1642. The first bolt 1641 may include a second head and a second screw. The second head of the first bolt 1641 may be located on a side of the third through hole k3 facing away from the fourth through hole k4, and the second screw may be located in the third through hole k3, the fourth through hole k4, and the first mounting hole k6. In this way, the first bolt 1641 can tighten and secure the first clamping plate 161 and the second clamping plate 162.

[0062] Please refer to Figure 5 、 Figure 8 and Figure 9 , Figure 8 This is a structural diagram of another walking machine roller adjustment structure 10 provided by an embodiment of the utility model. Figure 9 yes Figure 8 The diagram shows an exploded view of the treadmill roller adjustment structure 10. In an optional embodiment, the fixing member 1642 may include a tubular support g1, with a first mounting hole k6 located on the tubular support g1. The end of the tubular support g1 facing away from the second clamping plate 162 is fixedly connected to the treadmill support 14, and the end of the tubular support g1 proximal to the second clamping plate 162 abuts the second clamping plate 162. The tubular support g1 may be bonded or welded to the treadmill support 14, or the tubular support g1 and the treadmill support 14 may be an integral structure formed by an insert molding process. The insert molding process refers to a molding process in which a pre-prepared metal insert is placed in a mold, molten resin or plastic is injected, and the molten resin or plastic is bonded and solidified with the metal insert to form an integrated product. In this way, the first bolt 1641 can be connected to the first clamping plate 161, the second clamping plate 162 and the tubular support g1. The first bolt 1641 and the tubular support g1 can fix the first clamping plate 161 and the second clamping plate 162 on the treadmill bracket 14 while locking the first clamping plate 161 and the second clamping plate 162.

[0063] In an optional embodiment, the fixing member 1642 may also be a nut matching the first bolt 1641 .

[0064] Please refer to Figure 9 In an optional embodiment, the fixing member 1642 may further include a plurality of reinforcing ribs g2. The reinforcing ribs g2 are located outside the tubular support g1 and are respectively connected to the outer wall of the tubular support g1 and the treadmill support 14. The reinforcing ribs g2 can enhance the strength and rigidity of the tubular support g1 without increasing the wall thickness of the tubular support g1. This can prevent deformation of the tubular support g1 and reduce the weight of the tubular support g1. Consequently, the fixing member 1642 can have greater overall strength and rigidity despite being relatively lightweight.

[0065] A plurality of reinforcing ribs g2 can be provided on the outer side of the tubular support g1, and the number of the reinforcing ribs g2 can be adjusted according to the design strength of the fixing member 1642. When the design strength of the fixing member 1642 is relatively large, the number of the reinforcing ribs g2 can be appropriately increased to improve the structural strength of the tubular support g1, avoid deformation of the tubular support g1, and thereby improve the structural strength of the fixing member 1642.

[0066] Optionally, multiple reinforcing ribs g2 are evenly distributed around the circumference of the tubular support g1, ensuring uniform force distribution across the multiple reinforcing ribs g2. The reinforcing ribs g2 can be fixedly connected to the outer wall of the tubular support g1 and can also be fixedly connected to the treadmill support 14. For example, the reinforcing ribs g2 can be welded or bonded to the outer wall of the tubular support g1. Alternatively, the reinforcing ribs g2, tubular support g1, and treadmill support 14 can be an integrated structure manufactured through an insert injection molding process.

[0067] Please refer to Figure 8 、 Figure 9 and Figure 10 , Figure 10 This is a schematic structural diagram of another clamping assembly 16 provided in an embodiment of the present utility model. Figure 10 The illustrated clamping assembly 16 does not include the locking structure 164 within the clamping assembly 16. In an alternative embodiment, the treadmill frame 14 may include a base portion and support portions located on either side of the base portion, with the running belt wrapped around the base portion. The support portions may include a connected top plate 141 and side plates 142, with the top plate 141 and side plates 142 forming a receiving space. The clamping assembly 16 may be located within the receiving space and may further include a mounting portion 165, one end of which is connected to the first clamping plate 161 or the second clamping plate 162, and the other end of which is connected to the top plate 141 or the side plate 142. For example, the second clamping plate 162 is located on a side of the first clamping plate 161 near the top plate 141, with one end of the mounting portion 165 connected to the second clamping plate 162, and the other end of the mounting portion 165 connected to the top plate 141. In this manner, the mounting portion 165 can secure the clamping assembly 16 to the treadmill frame 14, further enhancing the stability of the clamping assembly 16. The other end of the mounting portion 165 may be welded, bonded, or bolted to the top plate 141 .

[0068] The second through hole k2 may be located on the side plate 142 , and the first end portion of the adjusting bolt 15 may also extend into the accommodating space through the second through hole k2 .

[0069] Please refer to Figure 8 , Figure 9 and Figure 10In an alternative embodiment, the treadmill support 14 may further include a support base 143 and a second bolt 144. The support base 143 is fixedly connected to the top plate 141. The support base 143 has a second mounting hole k7, into which the second bolt 144 is installed. The second bolt 144 is also connected to the mounting portion 165 to secure the mounting portion 165 to the support base 143. Exemplarily, the mounting portion has a fifth through-hole k8, through which one end of the second bolt 144 passes to secure the mounting portion 165 to the support base 143. The support base 143 may be welded or bonded to the top plate 141. Alternatively, the side plates 142, top plate 141, and support base 143 may be a single-piece structure manufactured through an insert injection molding process. By providing the support base 143 for mounting the second bolt 144, drilling holes in the top plate 141 of the treadmill support 14 can be avoided, thereby improving the overall strength and aesthetics of the treadmill support 14.

[0070] In an alternative embodiment, the first clamping plate 161 and the second clamping plate 162 can both be elastic members, with the first clamping plate 161 abutting against one side of the first end of the adjusting bolt 15, and the second clamping plate 162 abutting against the other side of the first end of the adjusting bolt 15. The first clamping plate 161 and the second clamping plate 162 can clamp the adjusting bolt 15 under the elastic force. In this way, when the treadmill roller adjustment structure 10 is subjected to external vibrations and the first bolt 1641 becomes loose, the supporting assembly can still rely on the elastic force of the first clamping plate 161 and the second clamping plate 162 to clamp the adjusting bolt 15, which can further improve the stability of the adjusting bolt 15.

[0071] It should be noted that, in the embodiment of the present utility model, Figure 3 and Figure 8 The first bolt 1641 is not shown. Figure 8 The second bolt 144 is not shown. Figure 8 and Figure 9 The walking machine roller adjustment structure shown is Figure 1 The structural schematic diagram of the back side of the treadmill roller adjustment structure is shown.

[0072] In summary, the present invention provides a treadmill roller adjustment structure comprising a corner guard structure, a roller assembly, a treadmill support, an adjustment bolt, and a clamping assembly. The roller assembly is threadedly connected to the adjustment bolt via a threaded through-hole. Rotation of the adjustment bolt drives the roller assembly to adjust the tightness of the running belt. Furthermore, the clamping assembly securely clamps the adjustment bolt and limits its position, preventing it from loosening due to external vibrations or deformation of the treadmill support. This improves the stability of the adjustment bolt and enhances the user experience.

[0073] An embodiment of the present application also provides a treadmill, which may include the treadmill roller adjustment structure of any of the above embodiments.

[0074] In the present invention, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.
