Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a rotatable 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. In weapon practice, this energy 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, which enhances the penetrating power and softening effect when striking.

[0003] Traditional wire-winding rods are mainly divided into two types: one is a solid wood design with both ends as one piece, and the other is a damped, rotatable design. With the one-piece design, friction occurs between the hand and the rod when performing various training movements, easily leading to calluses or blisters on the palms after prolonged training. The damped, rotatable design uses damping washers between the two ends to achieve damping friction. The tightness of the connection and the amount of damping are adjusted by a nut and connecting rod. In this damped rotation method, the friction between the two ends is relatively stiff when rotating the wire-winding rod back and forth, lacking a rebound effect, resulting in a poor training experience. Furthermore, prolonged training will cause wear on the damping washers, weakening the damping effect and requiring periodic adjustment of the wire-winding rod's damping.

[0004] Therefore, we propose a rotatable Tai Chi winding rod. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable Tai Chi winding rod to solve the aforementioned problems existing in the prior art.

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

[0007] A rotatable Tai Chi winding rod includes a rotation damping mechanism and two winding rod handles with mounting holes in the middle; the rotation damping mechanism includes a metal connecting rod, a fixing sleeve, a torsion spring, a spacer, and a sleeve.

[0008] Specifically, there are two fixing sleeves, which are movably fitted onto both ends of the metal connecting rod, and fixing grooves are provided on the outer side of the opposite end of each fixing sleeve.

[0009] Furthermore, the torsion spring is sleeved in the middle of the metal connecting rod and located between the two fixed sleeves, with both ends of the torsion spring locked in the fixing grooves of the two fixed sleeves.

[0010] Furthermore, the spacer sleeve is fitted onto the outer side of the middle part of the torsion spring.

[0011] Furthermore, there are two sleeves, which are respectively sleeved on the outer sides of both ends of the torsion spring, with one end of the sleeve sleeved on the outside of the fixed sleeve and the other end sleeved on the outside of the spacer sleeve.

[0012] Furthermore, the spacer is made entirely of metal, and a ring-shaped retaining ring is integrally formed in the middle of the spacer.

[0013] Furthermore, the two coiled rod handles are fitted onto both ends of the rotary damping mechanism through mounting holes, and the end faces of the two coiled rod handles slide against each other. Anchoring holes are present on both coiled rod handles and their corresponding sleeves, and the coiled rod handles and their corresponding sleeves are fixed together by anchoring bolts through the anchoring holes.

[0014] Furthermore, the inner walls at both ends of the sleeve are respectively attached to the outer surfaces of the fixed sleeve and the spacer sleeve, and the sleeve and the fixed sleeve are fixedly connected by fixing bolts.

[0015] Furthermore, each end of the metal connecting rod is fitted with a washer ring, one side of which is fitted with a fixing sleeve, and each end of the metal connecting rod, located outside the washer ring, is threaded with a positioning bolt.

[0016] Furthermore, the outer diameter of the washer ring is consistent with the outer diameter of the sleeve, and the outer diameter of the sleeve is adapted to the inner diameter of the mounting hole on the handle of the wire winding rod.

[0017] Furthermore, the fixing bolts, anchor bolts, and positioning bolts are all end cap hex bolts.

[0018] Beneficial effects:

[0019] This invention uses a rotary damping mechanism as its carrier. Two independently rotatable sleeves on the mechanism are used to mount the two handles of the winding rod. The handles are then connected to fixed sleeves with torsion springs via these sleeves. This allows the handles at both ends of the winding rod to achieve a damping rebound effect while maintaining rotatability. This effectively prevents friction between the hand and the handles during training, providing effective protection for the user's palms. It not only enhances the training experience but also allows the handles to return to their initial working state when no external force is applied. Furthermore, the damping rebound effect achieved by utilizing the characteristics of the torsion springs ensures that the damping rebound effect of the handles at both ends of the winding rod remains relatively stable over a long period, avoiding frequent maintenance.

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model.

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.

[0026] Example:

[0027] To address the issues of traditional Tai Chi winding rods causing calluses or blisters on the palms due to friction between the hands and the rod during various training movements, and the unsatisfactory training experience of damped, rotatable winding rods, which suffer from wear and tear on the damping pads over time, necessitating periodic adjustment of the damping, we propose a rotatable Tai Chi winding rod based on a damping rotation mechanism consisting of a torsion spring 104, a metal connecting rod 101, a fixed sleeve 102, and a sleeve 107. The specific technical solution is as follows:

[0028] like Figure 1-4 As shown, this embodiment provides a rotatable Tai Chi winding rod, including a rotation damping mechanism 1 and two winding rod handles 2 with mounting holes in the middle; the rotation damping mechanism 1 includes a metal connecting rod 101, a fixing sleeve 102, a torsion spring 104, a spacer 105 and a sleeve 107.

[0029] Specifically, there are two fixing sleeves 102, and the two fixing sleeves 102 are respectively movably fitted on both ends of the metal connecting rod 101. The outer side of the opposite end of each of the two fixing sleeves 102 is provided with a fixing groove 103. The torsion spring 104 is fitted in the middle of the metal connecting rod 101 and is located between the two fixing sleeves 102. The two ends of the torsion spring 104 are integrally formed with ring hooks. The torsion spring 104 is engaged in the fixing grooves 103 on the two fixing sleeves 102 through the hooks at both ends, so that the two fixing sleeves 102 and the torsion spring 104 are connected together.

[0030] The spacer 105 is made of metal, preferably copper alloy or stainless steel. The spacer 105 is fitted on the outer side of the middle part of the torsion spring 104, and the inner wall of the spacer 105 is in close contact with the outer side of the torsion spring 104. At the same time, in order to position the spacer 105, an annular retaining ring 106 is integrally formed in the middle part of the spacer 105. By using the retaining ring 106 and the sleeve 107 to limit the position, it can be ensured that the spacer 105 can always be in the middle position of the rotation damping mechanism 1.

[0031] In addition, there are two sleeves 107, which are respectively fitted on the outer sides of both ends of the torsion spring 104. At the same time, one end of the sleeve 107 is fitted on the outside of the fixed sleeve 102, and the other end is fitted on the outside of the spacer 105. The inner walls of both ends of the sleeve 107 are in contact with the outer surfaces of the fixed sleeve 102 and the spacer 105, respectively. The sleeve 107 and the fixed sleeve 102 are fixedly connected by a fixing bolt 108, wherein the fixing bolt 108 is a capless hexagonal socket head cap bolt. Fitting the sleeve 107 on the outside of the fixed sleeve 102 can position the snap-fit ​​position between the torsion spring 104 and the fixed sleeve 102, which can effectively prevent the end of the torsion spring 104 from disengaging from the slot on the fixed sleeve 102, thereby ensuring the stability of the assembly between the torsion spring 104 and the fixed sleeve 102.

[0032] Two wire-wound rod handles 2 are fitted onto both ends of the rotation damping mechanism 1 through mounting holes. The end faces of the two wire-wound rod handles 2 slide against each other. Anchor holes 3 are present on both the wire-wound rod handles 2 and their corresponding sleeves 107. The wire-wound rod handles 2 and their corresponding sleeves 107 are fixed together by anchor bolts 4 through the anchor holes 3. The anchor bolts 4 are end cap hex bolts. The wire-wound rod handles 2 are connected to the fixed sleeve 102 through the sleeves 107, thus allowing the two wire-wound rod handles 2 to rotate independently through the sleeves. 107 and the fixing sleeve 102 apply force to the torsion spring 104, and the elasticity of the torsion spring 104 itself achieves damping rebound, which can effectively avoid friction between the hand and the handle during training. It can effectively protect the user's palm and not only improve the experience during exercise, but also allow the two handles to return to their initial use state when the external force is removed. Moreover, the damping rebound achieved by the characteristics of the torsion spring 104 can keep the damping rebound effect of the handles at both ends of the coiled rod in a relatively stable state for a long time, avoiding frequent maintenance.

[0033] To prevent the positions of the two fixed sleeves 102 on the metal connecting rod 101 from changing and to improve the structural stability of the entire rotary damping mechanism 1 after assembly, a washer 109 is fitted at both ends of the metal connecting rod 101. One side of the washer 109 fits against the fixed sleeve 102, and the outer diameter of the washer 109 is the same as the outer diameter of the sleeve 107. A positioning bolt 110 is threaded at both ends of the metal connecting rod 101 and at the position outside the washer 109. The positioning bolt 110 is a capless hexagonal socket head cap bolt. The positioning bolt 110, in conjunction with the washer 109, is used to position the outer side of the fixed sleeve 102 and the end of the sleeve 107.

[0034] In order to improve the stability of the assembly between the coiled rod handle 2 and the rotary damping mechanism 1, the outer diameter of the sleeve 107 is adapted to the inner diameter of the mounting hole on the coiled rod handle 2, so that the damping rotary mechanism can fit more tightly with the coiled rod handle 2.

[0035] 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.
