Description

Technical Field

[0001] This utility model belongs to the technical field of fitness equipment, specifically relating to a martial arts fitness Tai Chi winding rod. Background Technology

[0002] Tai Chi Silk Reeling Stick is a unique training method that combines silk reeling energy in Tai Chi weapon practice. It uses the spiral movement of the waist and spine to drive the limbs to coil, forming a transmission chain of "root joints driving and tip joints leading the force". In weapon practice, this force can be extended to the stick. Through the forward and reverse silk reeling of the wrist and arm, the movement of the weapon presents a spiral trajectory, enhancing the penetrating power and softening effect when striking.

[0003] Currently, traditional Tai Chi coiling rods are designed with a single piece of wood at both ends. When using Tai Chi coiling rods to train the hands to hold the rod and perform various movements, there will inevitably be rotational friction between the hands and the rod. Long-term training can easily cause calluses or blisters to appear on the palms.

[0004] Therefore, we propose a martial arts fitness Tai Chi silk reeling stick. Utility Model Content

[0005] The purpose of this invention is to provide a martial arts fitness Tai Chi winding rod to solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A martial arts fitness Tai Chi winding rod includes a rotation damping mechanism and two handles. The rotation damping mechanism includes a central shaft, and a set of screwing components is installed at each end of the central shaft. The two sets of screwing components are symmetrically designed. An adapter hole for accommodating the screwing components is opened in the middle of each of the two handles.

[0008] Furthermore, each set of the screwing assembly includes a positioning sleeve, a fixing sleeve, a torsion spring, and a mounting sleeve; the end of the fixing sleeve has a fixing groove for fixing the torsion spring, and a positioning pin is integrally formed at the center of the fixing groove. One end of the torsion spring is fixed to the fixing sleeve, and the other end of the torsion spring is installed on the central shaft by a fixing screw; the mounting sleeve is sleeved on the outside of the fixing sleeve, the torsion spring, and the positioning sleeve. The positioning sleeve is installed at the end of the central shaft by a retaining spring, and the fixing sleeve is installed near the middle of the central shaft by a retaining spring. The fixing sleeve and the positioning sleeve are rotatably engaged with the central shaft. At the same time, the torsion springs in the two sets of screwing assemblies are arranged in opposite directions.

[0009] Furthermore, positioning holes are provided on both sides of the fixed sleeve, mounting sleeve, and handle. Each positioning hole is fitted with a capless hex bolt to fix the fixed sleeve, mounting sleeve, and handle together. When the user holds the handle for exercise or training, the handle is fixed to the mounting sleeve and fixed cap by the capless hex bolt. The force applied by the user to the handle is transmitted to the fixed sleeve, causing the fixed sleeves in the two sets of rotating assemblies to rotate in opposite directions. Since one end of the torsion springs on both rotating assemblies is fixed to the central shaft, when the fixed sleeve drives one end of the torsion spring to rotate, the other ends of the two torsion springs are fixed to the same central shaft. Therefore, the central shaft remains stationary when subjected to the force transmitted by the two torsion springs, so that the torsion springs will contract under the rotation of the fixed sleeve, generating elastic rotating resistance.

[0010] Furthermore, the ends of the fixed sleeves in the two sets of screwing assemblies slide and fit together. In order to improve the smoothness of the relative rotation of the handles at both ends of the winding rod and improve the user experience, an annular groove is provided at the center of the opposite side of the two fixed sleeves. A ball assembly fitted on the central shaft is installed in the annular groove. The ball assembly consists of an annular ball retainer and several spherical rollers installed on the ball retainer. At the same time, an annular ball groove is also provided on the end face of the opposite end of the two handles, and several steel balls are provided in the ball groove.

[0011] Since the handles are made of lightweight wood or plastic, in order to prevent the handles from cracking during long-term torsion, a clamp sleeve is fitted on the outside of the opposite ends of the two handles.

[0012] Furthermore, the outer diameter of the positioning sleeve is larger than the outer diameter of the fixed sleeve, and the inner side of the end of the mounting sleeve near the positioning sleeve is provided with a receiving groove that matches the outer diameter of the positioning sleeve. This design helps the user to quickly position the mounting sleeve using the positioning sleeve in conjunction with the snap ring.

[0013] Furthermore, the inner diameter of the other end of the mounting sleeve is adapted to the outer diameter of the positioning sleeve, and the outer side of the mounting sleeve is tightly fitted to the inner side of the adaptation hole provided in the middle of the handle. In this design, the mounting sleeve is used to limit the connection between the torsion spring and the fixed sleeve to prevent the end of the torsion spring from falling out of the fixed groove. At the same time, the two ends of the mounting sleeve are respectively fitted on the outside of the positioning sleeve and the fixed sleeve, which can make the central shaft and the outer handle form a coaxial design, so that the grip can be more smoothly coordinated with the entire screwing damping mechanism when it is twisted.

[0014] Beneficial effects:

[0015] This invention uses a rotary damping mechanism as its carrier, employing two sets of screwing components to install two handles. This allows the user to rotate the handles while gripping them tightly to perform training movements, effectively avoiding the friction that inevitably occurs between the hand and the handles during the use of traditional coiling rods. This provides effective protection for the user's palms. Furthermore, the torsion spring design in the screwing components provides a certain elastic damping effect to the handles at both ends of the coiling rod when rotating. This not only enhances the experience during exercise but also allows the two handles to return to their initial use state when the external force is removed. Attached Figure Description

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0023] Example:

[0024] In response to the one-piece design of traditional Tai Chi silk-winding sticks, which inevitably leads to rotational friction between the hand and the stick during use, long-term training can easily cause calluses or blisters on the palms. We propose a rotatable Tai Chi silk-winding stick; the specific solution is as follows:

[0025] like Figure 1-5 As shown, this embodiment provides a martial arts fitness Tai Chi winding rod, specifically including a rotation damping mechanism and two handles 8. The rotation damping mechanism includes a central shaft 1, and a set of screwing components are installed at each end of the central shaft 1. The two sets of screwing components are symmetrically designed. An adapter hole 9 for accommodating the screwing components is opened in the middle of each of the two handles 8.

[0026] like Figure 1-4 As shown, each set of screwing assemblies includes a positioning sleeve 3, a fixing sleeve 4, a torsion spring 5, and a mounting sleeve 7. The fixing sleeve 4 has a fixing groove 16 at its end for fixing the torsion spring 5. A positioning pin is integrally formed at the center of the fixing groove 16. One end of the torsion spring 5 is fixed to the fixing sleeve 4, while the other end of the torsion spring 5 is mounted on the central shaft 1 by a fixing screw 6. The mounting sleeve 7 is fitted over the outside of the fixing sleeve 4, the torsion spring 5, and the positioning sleeve 3. The positioning sleeve 3 is mounted on the end of the central shaft 1 by a retaining spring 2, while the fixing sleeve 4 is mounted on the central shaft 1 near the middle by a retaining spring 2. The fixing sleeve 4 and the positioning sleeve 3 are rotatably engaged with the central shaft 1. At the same time, the torsion springs 5 ​​in the two sets of screwing assemblies are arranged in opposite directions.

[0027] Positioning holes 15 are provided on both sides of the fixed sleeve 4, the mounting sleeve 7, and the handle 8. Each positioning hole 15 is fitted with a capless hex bolt 11 to fix the fixed sleeve 4, the mounting sleeve 7, and the handle 8 together. When the user holds the handle 8 for exercise or training, the handle 8 is fixed to the mounting sleeve 7 and the fixed cap through the capless hex bolt 11. The force applied by the user to the handle 8 is transmitted to the fixed sleeve 4, causing the fixed sleeve 4 in the two sets of rotating assemblies to rotate in opposite directions. Since one end of the torsion spring 5 on both rotating assemblies is fixed to the central shaft 1, when the fixed sleeve 4 drives one end of the torsion spring 5 to rotate, the other ends of the two torsion springs 5 ​​are fixed to the same central shaft 1. Therefore, the central shaft 1 remains stationary when subjected to the force transmitted by the two torsion springs 5, so that the torsion springs 5 ​​will contract under the rotation of the fixed sleeve 4, generating elastic rotating resistance.

[0028] The ends of the fixed sleeves 4 in the two sets of screwing assemblies slide and fit together. In order to improve the smoothness of the relative rotation of the handles 8 at both ends of the wire winding rod and improve the user experience, annular grooves 12 are provided at the center of the opposite side of the two fixed sleeves 4. A ball assembly 13 fitted on the central shaft 1 is installed in the annular groove 12. The ball assembly 13 consists of an annular ball retainer and several spherical rollers installed on the ball retainer. At the same time, annular ball grooves are also provided on the end faces of the opposite ends of the two handles 8, and several steel balls 14 are provided in the ball grooves.

[0029] Since the handles 8 are made of lightweight wood or plastic, in order to prevent the handles 8 from cracking during long-term torsion, a clamp sleeve 10 is fitted on the outside of the opposite end of the two handles 8.

[0030] The outer diameter of the positioning sleeve 3 is larger than that of the fixing sleeve 4. The inner side of the end of the mounting sleeve 7 near the positioning sleeve 3 is provided with a receiving groove that matches the outer diameter of the positioning sleeve 3. This design helps the user to quickly position the mounting sleeve 7 using the positioning sleeve 3 in conjunction with the snap ring 2.

[0031] The inner diameter of the other end of the mounting sleeve 7 is adapted to the outer diameter of the positioning sleeve 3. The outer side of the mounting sleeve 7 is tightly fitted to the inner side of the adapter hole 9 provided in the middle of the handle 8. In this design, the mounting sleeve 7 is used to limit the connection between the torsion spring 5 and the fixed sleeve 4 to prevent the end of the torsion spring 5 from falling out of the fixed groove 16. At the same time, the two ends of the mounting sleeve 7 are respectively fitted on the outer side of the positioning sleeve 3 and the fixed sleeve 4, which can make the central shaft 1 and the outer handle 8 form a coaxial design, so that the handle 8 can be more smoothly coordinated with the entire screwing damping mechanism when it is twisted.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
