[0001] The invention relates to the technical field of fitness equipment, in particular to a friction-type deceleration pulling fitness equipment which is easy to carry. Background Art

[0002] Fitness equipment is usually divided into two categories according to the number of training functions: single-function and comprehensive multi-function. Commonly used ones include rowing machines, fitness bikes, steppers, treadmills, waist beautification machines, etc.

[0003] At present, traditional fitness equipment is large in size and occupies a large space, and is inconvenient to move and carry. At the same time, during use, due to the different body shapes of different people, the length of their arm spans is also different. Therefore, it is necessary to adjust the distance between the two pull rings of the puller to achieve the best training effect. Therefore, the structure of the existing puller is often to install a long rod between the two pullers, which makes the puller long and inconvenient to carry. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a friction-type deceleration pulling fitness device that is easy to carry, which solves the problem that the structure of the existing pulling devices is often a long rod installed between two pulling devices, resulting in the pulling device being long and inconvenient to carry and use.

[0005] The present invention provides the following technical solution: a friction-type deceleration pulling fitness device that is easy to carry, comprising a storage box and two pulling fitness devices, wherein two threaded rods are rotatably connected between the inner side walls of the storage box via bearings, the thread directions of the two threaded rods are opposite, the outer surfaces of the two threaded rods are threadedly connected with threaded sleeves, the outer surfaces of the two threaded sleeves are fixedly installed with pedals, the two pulling fitness devices are respectively installed on the outer surfaces of the storage box, the outer surfaces of the two threaded rods are fixedly installed with transmission wheels, and a transmission belt is transmission-connected between the two transmission wheels.

[0006] Preferably, two slide grooves are provided on the inner side wall of the storage box, and a slider is slidably connected inside the two slide grooves, and the slider is fixedly connected to the threaded sleeve.

[0007] Preferably, one end of the threaded rod passes through and extends to the outside of the storage box, and a handle is fixedly installed thereon.

[0008] Preferably, the interior of the pedal is hollow, a fixing plate is fixedly installed between the inner side walls of the pedal, a threaded hole is opened on the outer surface of the fixing plate, a screw rod is connected to the inner thread of the threaded hole, one end of the screw rod is rotatably connected to a mounting cap, and the tension fitness device is fixedly installed on the outer surface of the mounting cap.

[0009] Preferably, two guide rods are fixedly mounted on the outer surface of the mounting cap, the guide rods are arranged parallel to the screw rod, and the first section of the guide rods penetrates and extends to the outside of the fixing plate.

[0010] Preferably, one end of the screw rod passes through and extends to the outside of the pedal, and is fixedly mounted with a twist cap.

[0011] Preferably, a limit plate is fixedly connected between one ends of the guide rods, and the limit plate is rotatably connected to the screw rod via a bearing.

[0012] Compared with the prior art, the present invention provides a friction-type deceleration pulling fitness device that is easy to carry and has the following beneficial effects:

[0013] (1) The portable friction-type deceleration tension fitness machine has a handle that is provided. By turning the handle, the handle drives the adjacent threaded rod to rotate, and the transmission wheel and transmission belt drive another threaded rod to rotate. Since the threads of the two threaded rods are in opposite directions, the two threaded sleeves move in opposite directions. The threaded sleeves drive the two tension fitness machines to move in opposite directions through the pedals and extend to the outside of the storage box, which is convenient for users to operate and use.

[0014] (2) The portable friction-type deceleration pulling fitness machine has a twist cap, which allows the user to rotate the screw rod by turning the twist cap. Since the screw rod is threadedly connected to the threaded hole, when the screw rod rotates, the mounting cap moves along the direction of the guide rod. The mounting cap drives the pulling fitness machine to move, which further adjusts the working length of the pedal, can meet different needs, and expands the working range of the device.

[0015] (3) The portable friction-type deceleration pulling fitness machine can be used by the user to exercise by stepping on the two pedals with both feet after adjusting the pedal length and pulling the operating ropes of the pulling fitness machine with both hands, which is convenient to use. When not in use, the pedals are first adjusted to the shortest length, and then the threaded rod is rotated in the reverse direction to store the two pedals and the pulling fitness machine inside the storage box, making the machine compact and easy to carry.

[0020] See also Figure 1-3 A portable friction-type deceleration tension fitness device comprises a storage box 1 and two tension fitness devices 5. The axes of the two tension fitness devices 5 are on the same horizontal line to meet the standards of human exercise and avoid damage to the body of users during exercise. Two threaded rods 2 are rotatably connected between the inner side walls of the storage box 1 through bearings. The thread directions of the two threaded rods 2 are opposite. When rotating synchronously, the threaded sleeves 3 can be moved relative to or back to back. The outer surfaces of the two threaded rods 2 are threadedly connected with threaded sleeves 3. The outer surfaces of the two threaded sleeves 3 are fixedly installed with pedals 4. The two tension fitness devices 5 are respectively installed on the outer surfaces of the storage box 1. The outer surfaces of the two threaded rods 2 are fixedly installed with transmission wheels. A transmission belt 6 is connected between the two transmission wheels for transmission.

[0021] Furthermore, in order to ensure that the threaded sleeve 3 can stably move along the direction of the threaded rod 2, two sliding grooves 7 are provided on the inner side wall of the storage box 1, and sliders 8 are slidably connected to the inside of the two sliding grooves 7. The sliders 8 are fixedly connected to the threaded sleeve 3, and the sliding grooves 7 are arranged parallel to the threaded rod 2. When the threaded rod 2 rotates, the threaded sleeve 3 and the sliders 8 can stably move along the direction of the sliding grooves 7.

[0022] Furthermore, to facilitate user operation, one end of the threaded rod 2 passes through and extends to the outside of the storage box 1, and a handle is fixedly installed. When in use, the user can drive the threaded rod 2 to rotate by turning the handle, which facilitates operation.

[0023] Furthermore, in order to adjust the working length of the pedal 4, the interior of the pedal 4 is hollow, and a fixing plate 9 is fixedly installed between the inner side walls of the pedal 4. A threaded hole 10 is opened on the outer surface of the fixing plate 9. The inner thread of the threaded hole 10 is connected with a screw rod 11, and one end of the screw rod 11 is rotatably connected with a mounting cap 12. The tension fitness device 5 is fixedly installed on the outer surface of the mounting cap 12. When in use, since the screw rod 11 and the threaded hole 10 are threadedly connected, the screw rod 11 is rotated to make the screw rod 11 drive the mounting cap 12 to move, and the mounting cap 12 drives the tension fitness device 5 to move, thereby adjusting the distance between the tension fitness device 5 and the adjacent threaded sleeve 3, thereby further expanding the scope of use.

[0024] Furthermore, in order to ensure that the mounting cap 12 can move stably, two guide rods 13 are fixedly installed on the outer surface of the mounting cap 12. The guide rods 13 are arranged parallel to the screw rod 11. The first section of the guide rod 13 penetrates and extends to the outside of the fixed plate 9. By setting the guide rod 13, the screw rod 11 is rotated, and the mounting cap 12 moves along the direction of the guide rod 13. The guide rod 13 has a restraining effect, ensuring that the mounting cap 12 can move stably and will not deviate.

[0025] Furthermore, in order to facilitate user operation, one end of the screw rod 11 passes through and extends to the outside of the pedal 4, and is fixedly installed with a twist cap. The user can rotate the screw rod 11 by turning the twist cap, which facilitates operation and use.

[0026] Furthermore, in order to ensure that the moving range of the mounting cap 12 is within the working range, a limit plate 14 is fixedly connected between one end of the guide rod 13, and the limit plate 14 is rotatably connected to the screw rod 11 through a bearing to prevent the mounting cap 12 from moving too much, causing the screw rod 11 to be pulled out of the threaded hole 10, thereby ensuring stable operation of the device.

[0027] In summary, the portable friction-type deceleration tension fitness device has a handle that is set, and by turning the handle, the handle drives the adjacent threaded rod 2 to rotate, and by the set transmission wheel and transmission belt 6, another threaded rod 2 is driven to rotate. Since the threads of the two threaded rods 2 are in opposite directions, the two threaded sleeves 3 move in opposite directions. The threaded sleeves 3 drive the two tension fitness devices 5 to move in opposite directions through the pedal 4, and extend to the outside of the storage box 1, so that the user can operate it conveniently.

[0028] By means of the twist cap, the user can rotate the screw rod 11 by turning the twist cap. Since the screw rod 11 is threadedly connected to the threaded hole 10, when the screw rod 11 rotates, the mounting cap 12 will move along the direction of the guide rod 13. The mounting cap 12 drives the tension fitness device 5 to move, thereby further adjusting the working length of the pedal 4, which can adapt to different needs and expand the working range of the device.

[0029] After adjusting the length of the pedal 4, the user can exercise by stepping on the two pedals 4 with both feet and pulling the operating rope of the tension fitness device 5 with both hands, which makes it easy to use. When not in use, the pedal 4 is first adjusted to the shortest length, and then the threaded rod 2 is rotated in the reverse direction to store the two pedals 4 and the tension fitness device 5 inside the storage box 1, which makes it compact and easy to carry.
