Description

Technical Field

[0001] This utility model relates to the field of tension belt technology, specifically a multifunctional tension belt device. Background Technology

[0002] Resistance bands are fitness equipment made of elastic materials, usually in the shape of a band, with a certain degree of elasticity and resistance. They are widely used in various fitness training, rehabilitation training and sports activities to help users increase muscle strength, improve body flexibility and coordination. Resistance bands are loved by many fitness enthusiasts because of their portability, ease of use and versatility.

[0003] While existing resistance bands can meet basic fitness needs to some extent, their simple structure and relatively limited function often fail to satisfy the diverse needs of users. Specifically, the length and resistance of traditional resistance bands are usually fixed and cannot be flexibly adjusted according to individual exercise intensity or goals. In addition, the ways to use traditional resistance bands are also relatively limited, mainly relying on the user's body parts (such as hands and feet) for fixation and stretching, lacking diverse exercise methods. These limitations make traditional resistance bands inadequate when dealing with complex and ever-changing fitness needs.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional tension belt device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-functional tension belt device, including a handle 1 and a handle 2 located on the same horizontal straight line, a box and a tension belt body. The box is fixed to the side wall of the handle 2 near the handle 1. The box is provided with a winding mechanism. The winding mechanism includes a fixed rod 1 horizontally rotatably disposed in the box. One end of the fixed rod 1 passes through the box and is fixed with a locking mechanism. The end of the locking mechanism away from the fixed rod 1 is rotatably provided with a knob. The locking mechanism includes an internal toothed ring 1 coaxially rotatably connected to the side wall of the knob near the fixed rod 1, an internal toothed ring 2 fixed to the side wall of the internal toothed ring 1 near the fixed rod 1, the internal toothed ring 2 fixed to the end of the fixed rod 1, a fixed seat fixed at the center of the side wall of the fixed rod 1 near the knob, the length direction of the fixed seat being consistent with the radial direction of the fixed rod 1, sliders sliding at both ends of the side wall of the fixed seat near the knob along its own length direction, pawls fixed on the side walls of the two sliders that are far apart from each other, and the two pawls respectively engaging with the internal toothed ring 1 and the internal toothed ring 2; One end of the tension belt body passes through the box and is fixed in the groove of the winding wheel. The other end of the tension belt body passes through the handle one and is fixed in the storage groove to the outer arc wall of the fixing rod two. The handle two has a pedal fixed on one end away from the handle one along its width direction on both outer side walls. The length direction of the pedal is consistent with the width direction of the handle two.

[0007] Furthermore, the gear teeth of the first and second internal gear rings rotate in opposite directions. A sliding channel is formed along the length of the fixed seat on the side wall near the knob. An oblique groove is formed on the side wall of the slider near the knob. The oblique grooves on the two sliders are arranged symmetrically about the axis of the fixed rod. The width of the fixed seat is greater than the sum of the axial lengths of the first and second internal gear rings. Two sliding pillars are fixed on the side wall of the knob near the fixed seat and are arranged symmetrically about the axis of the fixed rod. The two sliding pillars slide in the oblique grooves on the two sliders respectively. A fixed shaft is fixed at the center of the side wall away from the knob. The end of the fixed shaft away from the fixed rod is rotatably connected to the knob.

[0008] Furthermore, a return spring is fixed on the side wall of each of the two sliders that are close to each other. The end of the return spring away from the slider is fixed on the outer arc wall of the fixed shaft. The axial direction of the return spring is consistent with the length direction of the fixed seat. The two pawls are symmetrically arranged about the vertical plane where the axis of the fixed rod is located, and the two pawls are located in different vertical planes. A winding wheel is fixed on the outer arc wall of the fixed rod. The same tension belt body is fixed on the side wall of the handle and the box that are close to each other at the position corresponding to the winding wheel. A storage groove is opened at the top of the end of the handle near the second handle. An installation cover is installed at the top opening of the storage groove. The second fixed rod is horizontally arranged in the storage groove. A handle is fixed on the outer wall of the handle corresponding to the two ends of the second fixed rod.

[0009] Furthermore, the second fixed rod is parallel to the first fixed rod along its axis. The second fixed rod is coaxially arranged with the handle, and one of the handles is hollow along its axis. A limiting groove is coaxially formed on the side wall of the handle near the second fixed rod. Spline hoops are fixed at both ends of the outer arc wall of the second fixed rod. The spline hoops slide and adapt to the limiting groove. The end of the second fixed rod near the hollow handle slides inside the handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By combining the winding mechanism with the locking mechanism, the length of the resistance band can be flexibly adjusted to adapt to different exercise intensities. At the same time, the winding mechanism can easily wind up and unwind the resistance band, while the locking mechanism can ensure the stability and fixation of the resistance band at the required length, avoiding poor exercise results or safety hazards caused by the resistance band slipping during exercise.

[0011] 2. The design of the grips and pedals changes the traditional exercise method and provides more diverse exercise options. The grips make it easier for users to hold the resistance band and perform various movements, while the pedals allow users to fix their feet on the resistance band and perform more types of exercises such as leg stretches and squats. This not only increases the functionality of the resistance band, but also allows users to choose more suitable exercise methods according to their needs and preferences. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 To be continued Figure 6The present invention provides a multifunctional tension belt device, including a handle 10 and a handle 11 located on the same horizontal line, a housing 12 and a tension belt body 13. The housing 12 is fixed to the side wall of the handle 11 near the handle 10. The housing 12 is provided with a winding mechanism. The winding mechanism includes a fixed rod 20 horizontally rotatably disposed in the housing 12. One end of the fixed rod 20 passes through the housing 12 and is fixed with a locking mechanism. The end of the locking mechanism away from the fixed rod 20 is rotatably provided with a knob 16. The locking mechanism includes an internal gear ring 30 coaxially rotatably connected to the side wall of the knob 16 near the fixed rod 20. An internal gear ring 31 is fixed to the side wall of the internal gear ring 30 near the fixed rod 20. The internal gear ring 31 is fixed to the end of the fixed rod 20. A fixed seat 32 is fixed at the center of the side wall of the fixed rod 20 near the knob 16. The length direction of the fixed seat 32 is consistent with the radial direction of the fixed rod 20. Sliding blocks 33 are slidable at both ends of the side wall of the fixed seat 32 near the knob 16 along its own length direction. Pawls 34 are fixed on the side walls of the two sliding blocks 33 that are far apart from each other. The two pawls 34 respectively engage with the internal gear ring 30 and the internal gear ring 31. The gear teeth of the first internal gear ring 30 and the second internal gear ring 31 have opposite directions of rotation. A sliding channel is provided through the side wall of the fixed seat 32 near the knob 16 along its own length. An oblique groove is provided on the side wall of the slider 33 near the knob 16. The oblique grooves on the two sliders 33 are symmetrically arranged about the axis of the fixed rod 20. The width of the fixed seat 32 is greater than the sum of the axial length of the first internal gear ring 30 and the axial length of the second internal gear ring 31. Two sliding columns 35 are fixed on the side wall of the knob 16 near the fixed base 32. They are rotationally symmetrical about the axis of the fixed rod 20. The two sliding columns 35 slide in the inclined grooves on the two sliders 33 respectively. A fixed shaft is fixed at the center of the side wall away from the knob 16. The end of the fixed shaft away from the fixed rod 20 is rotatably connected to the knob 16. A return spring is fixed on the side wall of each of the two sliders 33 that are close to each other. The end of the return spring away from the slider 33 is fixed on the outer arc wall of the fixed shaft. The axial direction of the return spring is consistent with the length direction of the fixed seat 32. The two pawls 34 are symmetrically arranged about the vertical plane where the axis of the fixed rod 20 is located, and the two pawls 34 are located in different vertical planes.

[0016] It should be noted that: the outer wall of handle 21 is provided with a rotating channel that runs through the axis of fixed rod 20 at both ends; the inner toothed ring 30 and the inner toothed ring 31 are both fixed to the inner wall of the rotating channel. The inclined slide groove passes through the slider 33. The end of the slide post 35 away from the knob 16 is set in the inclined slide groove. When the knob 16 is rotated actively, whether the knob 16 is clockwise or counterclockwise, since the two pawls 34 are symmetrically arranged, that is, the rotation direction is opposite, one of the two pawls 34 will not obstruct the corresponding internal tooth ring 1 30 and internal tooth ring 2 31. For example, when the knob 16 rotates in one direction, the internal gear ring 30 and one of the pawls 34 will not block each other, but the internal gear ring 31 will block the other pawl 34. However, since the rotation of the knob 16 synchronously drives the slide column 35 to rotate, the slide column 35 will abut against the inner wall of the inclined groove on the slider 33, thereby forcing the slider 33 on that side to slide towards the axis of the knob 16, so that the pawl 34 on that side disengages from the internal gear ring 31 and can drive the fixed rod 20 to rotate. When the user actively rotates the knob 16, the knob 16 can rotate without obstruction. However, when the user pulls the handle 10 and the handle 11, the tension band body 13 will pull the winding wheel 21 to rotate. At this time, the driving end of the movement changes from the knob 16 to the fixed rod 20. When the fixed rod 20 rotates actively, since the fixed rod 20 cannot drive the slide 35 to rotate, no matter which direction the internal gear ring 30 and the internal gear ring 31 rotate, one of them will engage with the pawl 34 and thus cannot rotate, achieving the purpose of locking.

[0017] Please see the appendix Figure 1 To be continued Figure 6 The present invention provides a technical solution: a winding wheel 21 is fixed on the outer arc wall of the fixed rod 1 20, and the same tension belt body 13 is fixed on the side wall of the handle 1 10 and the box 12 close to each other at the position corresponding to the winding wheel 21. A storage groove is opened at the top of the end of the handle 1 10 close to the handle 2 11, and an installation cover 17 is installed at the top opening of the storage groove. The fixed rod 2 22 is horizontally arranged in the storage groove, and a handle 14 is fixed on the outer wall of the handle 1 10 at the positions corresponding to both ends of the fixed rod 2 22. The axial direction of the second fixing rod 22 is parallel to that of the first fixing rod 20. The second fixing rod 22 is coaxially arranged with the handle 14, and one of the handles 14 is hollow along its axial direction. A limiting groove is coaxially formed on the side wall of the handle 14 near the second fixing rod 22. Spline clamps 23 are fixed at both ends of the outer arc wall of the second fixing rod 22. The spline clamps 23 are slidably adapted to the limiting groove. One end of the second fixing rod 22 near the hollow structure of the handle 14 is slidably set inside the handle 14. One end of the tension belt body 13 passes through the box body 12 and is fixed in the groove of the winding wheel 21. The other end of the tension belt body 13 passes through the handle 10 and is fixed in the storage slot to the outer arc wall of the fixing rod 22. The handle 21 has a pedal 15 fixed on one end away from the handle 10 on both outer side walls along its width direction. The length direction of the pedal 15 is consistent with the width direction of the handle 21.

[0018] It should be noted that: the fixed rod 22 is fixed with a buckle at one end corresponding to the hollow handle 14. The buckle is specifically an "L"-shaped fixing plate, which makes it easy for the user to pull out the fixed rod 22 to replace the tension band body 13. The spline clamp 23 is used to prevent the fixed rod 22 from rotating. Furthermore, the fixing rod 22 and spline hoop 23 can be horizontally divided into two parts along the axial direction of the fixing rod 22, and then spliced ​​together with bolts. This allows the end of the tension band body 13 to be clamped and fixed, while the fixing rod 22 can also be pre-adjusted by winding. In addition, users can change the exercise method by holding the handle 14 and stepping on the pedal 15, or they can change to another exercise method by holding the first handle 10 and the second handle 11.

[0019] Working principle: By rotating the knob 16, the slide column 35 slides in the inclined groove of the slider 33, pushing the sliders 33 closer or further apart, so that the pawl 34 engages or disengages with the internal toothed ring 30 or the internal toothed ring 31, thereby controlling the rotation of the fixed rod 20. When the knob 16 is rotated actively, it can drive the fixed rod 20 and the winding wheel 21 to rotate, thereby enabling the tension belt body 13 to be wound up and down. When the user pulls the handle 10 and the handle 21, the fixed rod 20 rotates actively. Since it cannot drive the slide column 35 to rotate, the pawl 34 engages with the internal tooth ring, the fixed rod 20 is locked, and the length of the tension belt is fixed. One end of the resistance band body 13 is fixed to the winding wheel 21, and the other end is fixed to the fixed rod 22. The fixed rod 22 can be pulled out through the handle 14 to replace the resistance band. Users can also change the exercise method by holding the handle 14 or stepping on the pedal 15.
