Description

Technical Field

[0001] This utility model relates to the field of exercise equipment, specifically a main shaft assembly structure for an exercise device. Background Technology

[0002] Hand balance and coordination trainers are commonly used for hand rehabilitation and coordination training. They are designed with various functions, such as hand-eye coordination and active finger movement. Common types include solid wood hand balance training equipment and wooden hand balance and coordination pullers. These devices can help users perform hand rehabilitation exercises, enhance finger flexibility and hand strength. Hand-to-hand coordination exercise equipment can effectively exercise the muscles of the upper limbs, shoulders, and back, strengthen the body's core strength and stability. By pushing the support blocks back and forth with both hands, the muscles of the shoulders and back can be fully stretched and contracted, while simultaneously engaging the strength of the arms and exercising the muscles of the upper limbs. When using hand-to-hand coordination exercise equipment, a certain degree of stability is required to complete the movements correctly, which can enhance the body's stability and improve coordination. The use of this equipment requires strong physical flexibility to adapt to different loads, which is conducive to personal growth and progress.

[0003] However, existing hand balance coordination trainers still have the following problems during use:

[0004] To accommodate users of different age groups, existing hand balance coordination trainers use a spindle whose length can be adjusted via a thread. This alters the position of the support block for active hand movement, making operation inconvenient. Therefore, it is necessary to develop a spindle assembly structure for this exercise equipment in the current field of exercise equipment. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing hand balance coordination trainers, designed to be used by people of different ages, have a main shaft whose length can be adjusted via a thread. This changes the position of the support block for active hand movement, causing inconvenience in operation. This utility model proposes a new main shaft assembly structure for the training device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a main shaft assembly structure of an exercise device, including a support column and a movable shaft. An internally threaded tube is fixedly assembled on the top of the movable shaft. An externally threaded adjusting tube is threadedly assembled on one end of the internally threaded tube. A rotating cavity is provided inside the externally threaded adjusting tube. A movable groove is provided at one end of the externally threaded adjusting tube, and the movable groove communicates with the rotating cavity. A rotating disk is movably assembled on the rotating cavity. A correction tube is fixedly assembled on the rotating disk, and the correction tube is movably assembled with the movable groove.

[0007] Preferably, one end of the correction tube is fixedly fitted with an assembly rod, and the top of the assembly rod is fixedly fitted with a bearing block.

[0008] Preferably, the rotating disk has an inner cavity, on which a telescopic spring is fixedly mounted, and a limit push block is fixedly mounted at one end of the telescopic spring.

[0009] Preferably, a telescopic button is fixedly mounted on the limiting push block, and the telescopic button moves through the rotating disk.

[0010] Preferably, the telescopic button is engaged with the locking hole on the external threaded adjusting tube.

[0011] Preferably, guide blocks are fixedly mounted on both symmetrical sides of the support column.

[0012] Preferably, the guide block is movably assembled with the movable shaft.

[0013] Preferably, a connecting plate is fixedly mounted on the bottom of each movable shaft, a guide block is fixedly mounted on each connecting plate, and a guide rod is fixedly mounted on the bottom of each guide block.

[0014] The advantages of this utility model are:

[0015] This invention allows for the adjustment of an external threaded adjusting tube on an internally threaded tube. One end of the external threaded adjusting tube can rotate and move inside the internally threaded tube, increasing the usable length of both the internally and externally threaded adjusting tubes. This changes the position of the support block. Pressing the telescopic button causes the limiting push block to retract the telescopic spring. The rotating disk and the straightening tube rotate in the rotating cavity and movable groove, respectively. After adjusting the support block to its original position, releasing the telescopic button allows it to engage with the locking hole on the externally threaded adjusting tube under the elastic force of the telescopic spring, increasing the stability between the straightening tube and the externally threaded adjusting tube. This facilitates normal use for people of different ages. Users place their hands on the support block and actively apply force, causing the movable shaft to rotate on the guide block. Under the mutual traction of the two guide rods, the support block provides a workout for the hands. Attached Figure Description
