[0009] Specifically, when the second connecting seat is in the open position, the locking component is locked to the first connecting seat; when the second connecting seat is in the folded position, the locking component is disengaged from the first connecting seat.

[0010] In some embodiments, the locking assembly includes a first locking seat disposed on the side of the second connector facing the base, and when the second connector is in the open position, the first locking seat abuts against the side of the first connector facing the base.

[0011] In some embodiments, the locking component includes a locking mechanism that abuts against the side of the first connector away from the base when the second connector is in the open position.

[0016] In some embodiments, the locking mechanism further includes a stop seat disposed on the second connecting seat and located on the side of the first link opposite to the first connecting seat;

[0017] Specifically, when the second locking seat abuts against the side of the first connecting seat away from the base, the stop seat abuts against the side of the first connecting rod away from the first connecting seat.

[0018] In some embodiments, the handle and linkage assembly are located on opposite sides of the second connector.

[0021] The embodiments of this application have the following beneficial effects:

[0022] Based on the aforementioned adjustable locking device and fitness equipment, when the user needs to use the fitness equipment, that is, when the second connecting seat needs to be switched from the folded position to the open position, the body rotates relative to the base to an angled state. Then, the locking component on the second connecting seat locks it to the first connecting seat, thus locking the first and second connecting seats together and locking the second connecting seat in the open position. This prevents the body and base from continuing to rotate relative to each other, thereby enabling the body and base to unfold. When the user no longer needs to use the fitness equipment, that is, when the second connecting seat needs to be switched from the open position to the folded position, the locking component on the second connecting seat first disengages from the first connecting seat, allowing the first and second connecting seats to rotate relative to each other. Then, the body rotates relative to the base until it is in a state where the body is fitted against the base, thus switching the second connecting seat from the open position to the folded position, thereby enabling the body and base to fold. This application achieves the opening and folding of the body and base by rotating the first connecting seat and the second connecting seat. This prevents the fitness equipment from taking up too much space when folded, reduces the number of exposed parts, and lowers the risk of accidental collisions or tripping by the user. Secondly, the locking component locks the first and second connecting seats in the open position to prevent the body of the fitness equipment from tipping over when it is open. This ensures the safety of the fitness equipment when it is open while allowing the body and base to fold. Attached Figure Description

[0036] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0037] Figure 1 This diagram shows a structural schematic of a fitness device 1 according to an embodiment of this application. Figure 2 This diagram shows a structural schematic of the second connector 300 according to an embodiment of the present application. Figure 3 A schematic diagram of the adjusting locking device 10 according to an embodiment of this application is shown. See also: Figures 1 to 3 This application provides an adjustable locking device 10, which is applied to a fitness device 1, the fitness device 1 including a base 20 and a body 30. The adjustable locking device 10 includes: a first connecting seat 200, a second connecting seat 300, and a locking component 100.

[0038] For example, fitness equipment 1 can be a foldable device such as a resistance band or a treadmill, and is not limited thereto.

[0039] See Figure 2 and Figure 3 The first connecting seat 200 is used to connect to the base 20. The second connecting seat 300 is used to connect to the body 30. The second connecting seat 300 is rotatably connected to the first connecting seat 200 via a first rotating shaft 400, so that the second connecting seat 300 can switch between an open position and a folded position. The base 20 and the body 30 are connected through the first connecting seat 200 and the second connecting seat 300, allowing the base 20 and the body 30 to rotate relative to each other. The locking assembly 100 is connected to the second connecting seat 300.

[0040] When the second connecting seat 300 is in the open position, the base 20 and the body 30 are set at an angle, allowing the user to use the fitness equipment 1 normally. When the second connecting seat 300 is in the folded position, the body 30 fits against the base 20, thus reducing the space occupied by the fitness equipment 1.

[0041] For example, when the second connecting seat 300 is in the open position, the included angle between the base 20 and the body 30 can be selected between 60 degrees and 120 degrees, such as 80 degrees, 90 degrees, 100 degrees, etc.

[0042] When the second connecting seat 300 is in the open position, the locking component 100 locks with the first connecting seat 200, preventing both the first connecting seat 200 and the second connecting seat 300 from rotating further. When the second connecting seat 300 is in the folded position, the locking component 100 disengages from the first connecting seat 200.

[0043] According to the embodiments of this application, when a user needs to use the fitness equipment 1, that is, when the second connecting seat 300 needs to be switched from the folded position to the open position, the body 30 rotates relative to the base 20 to an angle state, and then the locking component 100 provided on the second connecting seat 300 locks with the first connecting seat 200, so that the first connecting seat 200 and the second connecting seat 300 are locked together, thereby locking the second connecting seat 300 in the open position, so that the body 30 and the base 20 can no longer rotate relative to each other, thereby realizing the unfolding of the body 30 relative to the base 20. When the user no longer needs to use the fitness equipment 1, that is, when the second connecting seat 300 needs to be switched from the open position to the folded position, the locking component 100 set on the second connecting seat 300 is first disengaged from the first connecting seat 200, so that the first connecting seat 200 and the second connecting seat can rotate relative to each other. Then, the body 30 rotates relative to the base 20 until the body 30 is in contact with the base 20, so that the second connecting seat 300 is switched from the open position to the folded position, thereby realizing the folding of the body 30 and the base 20. This application achieves the opening and folding of the body 30 and the base 20 by rotating the first connecting seat 200 and the second connecting seat 300. This ensures that the fitness equipment 1 does not take up too much space when folded, reduces the exposed parts of the fitness equipment 1, and lowers the risk of accidental collision or tripping by the user. Secondly, the locking component 100 locks the first connecting seat 200 and the second connecting seat 300 in the open position to prevent the body 30 of the fitness equipment 1 from tipping over when in the open position. While enabling the body 30 and the base 20 to achieve the folding function, it also ensures the safety of the fitness equipment 1 when in the open position.

[0044] In some embodiments, see Figure 2 and Figure 3The locking assembly 100 includes a first locking seat 110, which is disposed on the side of the second connecting seat 300 facing the base 20. When the second connecting seat 300 is in the open position, the first locking seat 110 abuts against the side of the first connecting seat 200 facing the base 20.

[0045] For example, the length direction of the base 20 is the first direction, the width direction of the base 20 is the second direction, the base 20 and the adjustment and locking structure are arranged adjacent to each other along the first direction, the first connecting seat 200 and the second connecting seat 300 are staggered in the first direction, and the first connecting seat 200 and the first locking seat 110 overlap in the first direction so that when the second connecting seat 300 is in the open position, the first locking seat 110 abuts against the side of the first connecting seat 200 facing the base 20. With this arrangement, when it is necessary to switch the second connecting seat 300 from the folded position to the open position, the body 30 rotates relative to the base 20 to a predetermined angle. At this time, the first locking seat 110 and the first connecting seat 200 abut against each other to prevent the body 30 from continuing to unfold relative to the base 20. When the first locking seat 110 and the first connecting seat 200 abut against each other, the angle between the body 30 and the base 20 is a predetermined angle, which helps to ensure the stability of the fitness equipment 1.

[0046] In some embodiments, see Figure 2 and Figure 3 The locking assembly 100 includes a locking mechanism 120. When the second connecting seat 300 is in the open position, the locking mechanism 120 abuts against the side of the first connecting seat 200 away from the base 20. With this configuration, the locking mechanism 120 and the first locking seat 110 abut against the opposite sides of the first connecting seat 200 in the first direction, thereby locking the second connecting seat 300 and the first connecting seat 200 in the open position. This stabilizes the body 30 and the base 20 at a predetermined angle, which helps to improve the stability of the fitness equipment 1 in the open position.

[0047] In some embodiments, see Figure 2 and Figure 3 The locking mechanism 120 includes a handle 121, a linkage assembly, and a second locking seat 125. The handle 121 is rotatably connected to the second connecting seat 300 via a second rotating shaft 140. The linkage assembly includes a first link 122, a second link 123, and a third link 124. One end of the first link 122 is connected to the second rotating shaft 140, the other end of the first link 122 is rotatably connected to one end of the second link 123, the other end of the second link 123 is rotatably connected to one end of the third link 124, the other end of the third link 124 is connected to the second locking seat 125, and the third link 124 is rotatably connected to the second rotating seat via a third rotating shaft 150.

[0048] When the second connecting seat 300 is in the open position, the second locking seat 125 abuts against the side of the first connecting seat 200 away from the base 20.

[0049] In the embodiments of this application, see Figure 2 and Figure 3 The first link 122, the second link 123, and the third link 124 constitute a three-bar linkage. For example, when the user rotates the handle 121, the first link 122 rotates around the second pivot 140, causing the first link 122 to rotate the second link 123. This, in turn, causes the second link 123 to rotate the third link 124 around the third pivot 150, thereby causing the second locking seat 125 to rotate around the third pivot 150. When the second connecting seat 300 is in the folded position, the user can use the handle 121 to engage the second locking seat 125 against the side of the first connecting seat 200 away from the base 20, thus locking the second connecting seat 300 and the first connecting seat 200 in the open position. This stabilizes the body 30 and the base 20 at a predetermined angle, improving the stability of the fitness equipment 1 in the open position. Secondly, when the second connecting seat 300 needs to be rotated from the open position to the folded position, the handle 121 is used to drive the second locking seat 125 to disengage from the side of the first connecting seat 200 away from the base 20, so that the second connecting seat 300 can be folded toward the base 20, thereby realizing the opening and folding of the body 30 and the base 20.

[0050] In some embodiments, see Figure 2 and Figure 3 The second locking seat 125 includes a locking part 125a and a connecting part 125b. The second connecting seat 300 has a sliding channel defined on it. The locking part 125a and the connecting part 125b are connected. At least a portion of the connecting part 125b slides in the sliding channel. With this configuration, the position of the locking part 125a extending out of the second connecting seat 300 can be adjusted by sliding the connecting part 125b in the sliding channel. This allows for fine-tuning of the locking part 125a, resulting in a better fit between the locking part 125a and the side of the first connecting seat 200 away from the base 20. This is beneficial for improving the stability of the base 20 and the body 30 when the fitness equipment 1 is in the open position.

[0051] In some embodiments, the sliding channel is provided with an internal thread, and at least a portion of the connecting part 125b is provided with an external thread that is adapted to the internal thread. The position of the locking part 125a extending out of the second connecting seat 300 can be adjusted by the cooperation of the external thread and the internal thread, so as to achieve fine adjustment of the locking part 125a.

[0052] It should be noted that in the above embodiments, the connecting part 125b and the locking part 125a are an integral structure, for example, the connecting part 125b and the locking part 125a constitute a nut structure. It is understood that the connecting part 125b and the locking part 125a can also be separate structures, and the connecting part 125b and the locking part 125a can be connected together by a threaded connection, which is not limited here.

[0053] In some embodiments, see Figure 2 and Figure 3 The locking mechanism 120 also includes a stop seat 130, which is disposed on the second connecting seat 300 and located on the side of the first connecting rod 122 away from the first connecting seat 200.

[0054] In this embodiment, when the second locking seat 125 abuts against the side of the first connecting seat 200 away from the base 20, the stop seat 130 abuts against the side of the first connecting rod 122 away from the first connecting seat 200, thereby limiting the first connecting rod 122. In this embodiment, when the first connecting rod 122 abuts against the stop seat 130, the locking part 125a and the side of the first connecting seat 200 away from the base 20 are in contact, causing the stop seat 130 to limit the locking part 125a, preventing the locking part 125a from applying excessive pressure to the side of the first connecting seat 200 away from the base 20, thus preventing damage to the contact point between the first connecting seat 200 and the locking part 125a.

[0055] It should be noted that the handle 121 in the above embodiment has a self-locking structure, so that when the handle 121 drives the second locking seat 125 to abut against the side of the first connecting seat 200 away from the base 20, the handle 121 can lock the position of the second locking seat 125 through self-locking, so that the second locking seat 125 cannot continue to rotate under external force, which is beneficial to improving the stability of the base 20 and the body 30 when the fitness equipment 1 is in the open position.

[0056] For example, the self-locking structure of the handle 121 can be a ratchet structure, which achieves self-locking through the cooperation of ratchet teeth and pawls. When the handle 121 rotates, the pawl will engage the ratchet teeth. The self-locking structure can also be a spring pin locking structure, in which the handle 121 is self-locked by a spring pin. When the handle 121 is rotated to the correct position, the spring pin will automatically spring into a preset hole, locking the position of the handle 121. It is understood that the self-locking structure of the handle 121 is not limited here.

[0057] In some embodiments, see Figure 2 and Figure 3The handle 121 and the linkage assembly are located on opposite sides of the second connecting seat 300, while the linkage assembly and the first connecting seat 200 are located on the same side of the second connecting seat 300. This design ensures that the user is not interfered with by the first connecting seat 200 and the linkage assembly when operating the handle 121, reducing potential obstacles during operation. It also prevents the user from accidentally touching the linkage assembly while operating the handle 121, reducing the possibility of operational errors and improving the safety of the equipment.

[0058] As another aspect of the application's implementation, see Figures 1 to 3 This application provides a fitness device 1, which includes: a base 20, a body 30, and an adjustment and locking device 10 as described in any of the above embodiments. A first connecting seat 200 is connected to the base 20, and a second connecting seat 300 is connected to the body 30. Thus, this display device possesses all the features and advantages of the aforementioned double-sided display module 1, which will not be repeated here. In general, when a user needs to use the fitness device 1, that is, when the second connecting seat 300 needs to be switched from the folded position to the open position, the body 30 rotates relative to the base 20 to an angle. Then, the locking component 100 disposed on the second connecting seat 300 locks it to the first connecting seat 200, thereby locking the first connecting seat 200 and the second connecting seat 300 in the open position, preventing the body 30 and the base 20 from continuing to rotate relative to each other, thus realizing the unfolding of the body 30 relative to the base 20. When the user no longer needs to use the fitness equipment 1, that is, when the second connecting seat 300 needs to be switched from the open position to the folded position, the locking component 100 set on the second connecting seat 300 is first disengaged from the first connecting seat 200, so that the first connecting seat 200 and the second connecting seat can rotate relative to each other. Then, the body 30 rotates relative to the base 20 until the body 30 is in contact with the base 20, so that the second connecting seat 300 is switched from the open position to the folded position, thereby realizing the folding of the body 30 and the base 20. This application achieves the opening and folding of the body 30 and the base 20 by rotating the first connecting seat 200 and the second connecting seat 300. This ensures that the fitness equipment 1 does not take up too much space when folded, reduces the exposed parts of the fitness equipment 1, and lowers the risk of accidental collision or tripping by the user. Secondly, the locking component 100 locks the first connecting seat 200 and the second connecting seat 300 in the open position to prevent the body 30 of the fitness equipment 1 from tipping over when in the open position. While enabling the body 30 and the base 20 to achieve the folding function, it also ensures the safety of the fitness equipment 1 when in the open position.

[0059] In some embodiments, the base 20 and the adjustment locking structure are arranged adjacent to each other along the first direction, and the number of adjustment locking structures is two. The two adjustment locking structures are arranged at intervals along the second direction, that is, the two adjustment locking structures are arranged at intervals along the width direction of the base 20. By increasing the number of adjustment locking structures, the force on the base 20 and the body 30 in the open position is increased, which helps to increase the stability of the fitness equipment 1 in the open position.

[0060] The first direction and the second direction intersect. For example, the first direction and the second direction are perpendicular. Here, "perpendicular" not only includes the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering, such as "perpendicular" referring to the state where the angle formed by a line and a line, a line and a surface, or a surface and a surface is 89° to 91°.
