Description

Technical Field

[0001] The present invention belongs to the field of Pilates beds, and particularly relates to a device for adjusting the handrail rod part of a Pilates bed. Background Art

[0002] In the modern fitness field, Pilates, as a form of exercise that emphasizes core muscle group training and improves body flexibility and balance ability, has been widely welcomed. As one of the important apparatuses in Pilates exercise, the design and function of the Pilates bed play a crucial role in the user's exercise experience and effect.

[0003] Currently, for the common Pilates beds on the market, there are generally some problems with the gear settings at the handrail rod part. Some Pilates beds are designed with the function of adjusting the gear with one hand operation. The original intention is to facilitate the user to adjust according to their own feelings at any time during the exercise. However, in actual use, this design is prone to misoperation because when exercising, the user's body is in a dynamic state, and the stability and accuracy of one - hand operation are difficult to guarantee. Once an operation error occurs, it may cause the gear of the handrail rod to suddenly change, resulting in the user who is exercising losing balance and causing accidental injury, seriously affecting the user's safety and use experience. In summary, the existing gear setting method of the Pilates bed handrail rod needs to be improved to enhance the user's use convenience and safety;

[0004] Therefore, a device for adjusting the handrail rod part of a Pilates bed is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the embodiment of the present invention is to provide a device for adjusting the handrail rod part of a Pilates bed to solve the problems proposed in the above background art.

The handrail rod includes a cross - bar, both ends of the cross - bar are connected to a rotating rod. A through - slot is formed through the side surface of the rotating rod. A first limiting rod and a second limiting rod are connected inside the rotating rod. A pin rod passes through the rotating rod, and the pin rod is threadedly connected to the side surface of the Pilates bed main body. Threaded rods are connected to the bottoms of the rotating rods;

[0008] The fixing member includes a fixing plate, a number of clamping holes are formed inside the fixing plate, and the fixing plate is connected to the side surface of the Pilates bed main body by bolts;

[0009] The adjusting member includes a movable frame, the movable frame is arranged inside the rotating rod, a threaded sleeve is inserted into the movable frame, an operating rod is in threaded connection with the threaded sleeve, the operating rod is slidably connected in the through groove, an adjusting hole is formed in the back surface of the movable frame, a spring is connected to the bottom end of the movable frame, and the bottom end of the spring is connected to the threaded rod;

[0010] The clamping member includes a push rod, the push rod is slidably connected in the adjusting hole, a clamping rod is clamped outside the push rod, the clamping rod is inserted into one of the clamping holes, and the clamping rod is slidably connected in the rotating rod.

[0011] By arranging the above structure, by pressing the operating rods simultaneously, the resistance level of the Pilates bed is adjusted to achieve different exercise effects.

[0012] Further technical solution, first limiting holes and second limiting holes are formed in both the front surface and the back surface of the movable frame.

[0013] Further technical solution, a sliding hole is formed in the side surface of the movable frame, and the clamping rod is arranged in the sliding hole.

[0014] Further technical solution, a plurality of the clamping holes are distributed in a circumferential array around the pin rod.

[0015] Further technical solution, the first limiting rod is slidably connected in the first limiting hole, and the second limiting rod is slidably connected in the second limiting hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the present invention, when both hands pull the two operating rods upward simultaneously, the moving operating rods drive the movable frame to move through the threaded sleeves, the two moving movable frames drive the adjusting holes to move upward, the two upward moving adjusting holes move away from each other through the push rods, the two clamping rods moving away from each other both move out of the clamping holes, and then the rotating rod is pushed to rotate around the pin rod through the operating rod. When the two rotating rods move to the appropriate gears, the two operating rods are slowly released, and the two clamping rods moving closer to each other move into the corresponding clamping holes. At this time, the armrest rod can be adjusted to the corresponding resistance gear, enabling the user to easily adjust each resistance gear of the Pilates bed according to different needs, with convenient operation;

[0019] In the present invention, since the device needs to be pressed simultaneously with both hands to adjust the gear, the resistance gear of the device is not easily adjusted due to accidental touch, increasing the use safety of the device;

[0030] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0031] Embodiment 1

[0032] As Figures 1-6As shown in the figure, an embodiment of the present invention provides a device for adjusting the armrest rod part of a Pilates bed, which includes an armrest rod 1, a fixing member 2, a Pilates bed main body 3, an adjusting member 4 and a clamping member 5, and is characterized in that: the armrest rod 1 includes a cross bar 12, both ends of the cross bar 12 are connected to a rotating rod 11, a through groove 13 is formed through the side surface of the rotating rod 11, a first limiting rod 14 and a second limiting rod 15 are connected inside the rotating rod 11, a pin rod 16 passes through the rotating rod 11, and the pin rod 16 is threadedly connected to the side surface of the Pilates bed main body 3, and threaded rods 17 are threadedly connected to the bottom of the rotating rod 11;

[0033] The fixing member 2 includes a fixing plate 21, several clamping holes 22 are formed in the fixing plate 21, and the fixing plate 21 is connected to the side surface of the Pilates bed main body 3 by bolts;

[0034] The adjusting member 4 includes a movable frame 41, the movable frame 41 is arranged inside the rotating rod 11, a threaded sleeve 42 is inserted into the movable frame 41, an operating rod 43 is threadedly connected inside the threaded sleeve 42, the operating rod 43 is slidably connected in the through groove 13, an adjusting hole 46 is formed in the back surface of the movable frame 41, a spring 48 is connected to the bottom end of the movable frame 41, and the bottom end of the spring 48 is connected to the threaded rod 17;

[0036] In this embodiment, when it is necessary to adjust the resistance gear of the armrest rod 1, the operating rods 43 are pulled upward simultaneously with both hands. The moving operating rods 43 drive the movable frame 41 to move through the threaded sleeves 42. The moving movable frame 41 drives the first limiting hole 44, the second limiting hole 45, the adjusting hole 46 and the sliding hole 47 to move. The moving first limiting hole 44 slides outside the first limiting rod 14, the moving second limiting hole 45 slides outside the second limiting rod 15, the upward moving sliding hole 47 slides outside the clamping hole 22, and the two upward moving adjusting holes 46 drive the two push rods 51 to move away from each other. The two mutually separating push rods 51 both slide outside the rotating rod 11, and the two mutually separating clamping rods 52 both move out of the clamping holes 22. Then, the rotating rod 11 is pushed by the operating rod 43 to rotate around the pin rod 16. At the same time, the two upward moving movable frames 41 both stretch the spring 48. When the two rotating rods 11 move to the appropriate gear, the two moving rotating rods 11 both drive the clamping rods 52 to the corresponding clamping holes 22. Then, the two operating rods 43 are slowly released. The movable frame 41 moves downward under the action of the elastic force of the spring 48. The downward moving movable frame 41 drives the adjusting hole 46 to move downward. The two downward moving adjusting holes 46 both drive the two clamping rods 52 to move closer to each other through the push rods 51. The two mutually approaching clamping rods 52 move into the corresponding clamping holes 22. At this time, the armrest rod 1 can be adjusted to the corresponding resistance gear;

[0037] Specifically, the front and back of the movable frame 41 are both provided with a first limiting hole 44 and a second limiting hole 45. The first limiting rod 14 is slidably connected in the first limiting hole 44, and the second limiting rod 15 is slidably connected in the second limiting hole 45.

[0039] Specifically, a sliding hole 47 is provided on the side of the movable frame 41, and the clamping rod 52 is arranged in the sliding hole 47.

[0040] In this embodiment, since the clamping rod 52 is slidably connected in the sliding hole 47, the clamping rod 52 can limit the moving movable frame 41 through the sliding hole 47.

[0041] Specifically, several clamping holes 22 are arranged in a circular array around the pin rod 16.

[0042] In this embodiment, the rotating rod 11 in rotation can drive the clamping rod 52 to accurately move to the position aligned with the clamping hole 22 in sequence around the pin rod 16.

[0043] Specifically, the shape of the adjusting hole 46 is set to be arc-shaped.

[0044] In this embodiment, when the movable frame 41 drives the adjustment hole 46 to move, since the adjustment hole 46 is set to be arc-shaped, the arc-shaped adjustment hole 46 can drive the push rod 51 to slide within the rotating rod 11.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
