Description

Technical Field

[0001] This utility model relates to the field of neck exerciser technology, and in particular to a portable neck exerciser with adjustable resistance. Background Technology

[0002] Modern work and entertainment methods heavily rely on computers and mobile phones, leading to prolonged periods of poor posture with heads down, constantly harming cervical spine health. Resistance exercises targeting the neck muscles can enhance muscle strength and elasticity, effectively maintaining the biomechanical balance of the cervical spine. The head-hand resistance training method, also known as "isometric contraction exercise of the posterior neck muscles," is widely recognized in the medical rehabilitation field and is a method with reliable literature support for the prevention and treatment of cervical spondylosis. However, the above exercises require hand coordination, and prolonged practice can lead to arm fatigue. Therefore, some devices have emerged to replace the hands for neck exercises.

[0003] For example, Chinese Patent No. CN114669017A discloses a neck strength ring for neck muscle training, which belongs to the technical field of fitness exercise equipment and medical rehabilitation equipment. It includes a head support ring, a handle, and a shoulder support ring. The head support ring is located above the shoulder support ring, and the handle is connected between the head support ring and the shoulder support ring.

[0004] These neck exercise devices consist of a headrest, shoulder rests, and resistance components. The user rests their head and shoulders against the headrest and shoulder rests respectively, grips the resistance components with both hands, and exercises by tilting their head backward to resist the resistance provided by the elastic components (such as torsion springs or straight springs). However, these devices have a significant technical limitation: the resistance level is not adjustable, failing to meet the different exercise intensity needs of different users at different stages.

[0005] Therefore, this application proposes a portable neck exerciser with adjustable resistance to solve the above problems. Utility Model Content

The two ends of the multiple vortex elastic bands are respectively fixedly connected to the outer end of the second connecting shaft and the inner wall of the end of the upper half ring, and the multiple vortex elastic bands are distributed in a ring array around the central axis of the second connecting shaft.

[0011] Preferably, the resistance component includes a third resistance mechanism, which is installed between the upper half ring and the lower half ring. The third resistance mechanism includes an elastic ring, with a stabilizing cover fitted at the top and bottom of the elastic ring. A movable clamp is fixedly connected to the outside of the stabilizing cover, and two movable clamps are respectively fitted onto the outer ends of the upper half ring and the lower half ring.

[0030] Please see Figure 1-12 The technical solution provided by this utility model specifically includes the following embodiments:

[0031] In one embodiment, the present invention includes an exerciser body 1, which is composed of an upper half ring 11 and a lower half ring 12 distributed vertically, and the ends of the upper half ring 11 and the lower half ring 12 are movably connected.

[0032] A resistance element is connected between the upper half ring 11 and the lower half ring 12. The resistance element is used to adjust the resistance when the upper half ring 11 and the lower half ring 12 are bent.

[0033] The resistance component includes a first resistance mechanism 2, which is connected at the end connection of the upper half ring 11 and the lower half ring 12. The first resistance mechanism 2 consists of a connecting shaft 21, a coil spring 22, a ratchet 23, a pawl 24, a spring 25, a button 26, and a knob 27. The coil spring 22 is connected to the inner wall of the upper half ring 11, and the outer end of the coil spring 22 is engaged with the inner wall of the upper half ring 11. The connecting shaft 21 is movably connected between the ends of the upper half ring 11 and the lower half ring 12, and the inner end of the coil spring 22 is engaged with the outer end of the connecting shaft 21. Ratchet 23 is fixedly connected to the outer end of connecting shaft 21. Pad 24 is movably connected to the inner wall of the lower half ring 12, and ratchet 23 and pad 24 mesh with each other. The two ends of spring 25 are fixedly connected to the outer side of pad 24 and the inner wall of the lower half ring 12, respectively. Button 26 is slidably connected to the outer side of the lower half ring 12, and extends into the inner wall of the lower half ring 12. The end of button 26 abuts against pad 24. Knob 27 is fixedly connected to the end of connecting shaft 21, and knob 27 is located on the outer side of the lower half ring 12.

[0034] The first adjustment part, consisting of ratchet 23, pawl 24, spring 25, button 26, and knob 27, works in conjunction with coil spring 22 to adjust the resistance. When using the first resistance mechanism 2 to adjust the resistance between the upper half ring 11 and the lower half ring 12, the connecting shaft 21 can be rotated via knob 27. Rotation of the connecting shaft 21 tightens the coil spring 22, increasing its preload. This increases the resistance between the upper half ring 11 and the lower half ring 12. The rotation of the connecting shaft 21 causes the ratchet 23 to rotate synchronously. When the ratchet 23 rotates clockwise, the pawl 24 does not interfere. However, when the ratchet 23 rotates counterclockwise… When in motion, the pawl 24, pushed by the spring 25, engages the ratchet 23, preventing it from rotating counterclockwise. This avoids the problem of self-recovery after the resistance increases. When it is necessary to reduce the resistance, the button 26 can be pushed by hand to slide. When the button 26 slides, it will press against the end of the pawl 24, preventing the pawl 24 from engaging and locking the ratchet 23. At this time, the ratchet 23 rotates counterclockwise with the connecting shaft 21 under the deformation recovery action of the coil spring 22. The coil spring 22 will also loosen as the connecting shaft 21 rotates in the opposite direction, reducing its preload and thus reducing the resistance between the upper half ring 11 and the lower half ring 12.

[0035] In addition, even without installing the first adjustment part, only the coil spring 22 can be installed to meet different resistance requirements by replacing the coil spring 22 with one of different preloads. At the same time, there are two connection points between the upper half ring 11 and the lower half ring 12. Depending on the requirements, a resistance element can be installed at one connection point, and a conventional shaft can be used for the other connection point. This also provides resistance adjustment function and reduces costs. Alternatively, resistance elements can be installed at both connection points, selectively installed according to actual needs.

[0036] In embodiment two, the resistance component includes a second resistance mechanism 3, which is connected at the end connection of the upper half ring 11 and the lower half ring 12. The second resistance mechanism 3 consists of a connecting shaft 31, a spiral elastic band 32, a ratchet 33, a pawl 34, a spring 35, a button 36, and a knob 37. The connecting shaft 31 is movably connected between the ends of the upper half ring 11 and the lower half ring 12. Multiple spiral elastic bands 32 are provided, with their ends fixedly connected to the outer end of the connecting shaft 31 and the inner wall of the upper half ring 11, respectively. The multiple spiral elastic bands 32 are connected to the connecting shaft 31. The central axis of the second shaft 31 is arranged in a circular array. The second ratchet 33 is fixedly connected to the outer end of the second shaft 31. The second pawl 34 is movably connected to the inner wall of the lower half ring 12, and the second ratchet 33 and the second pawl 34 mesh with each other. The two ends of the second spring 35 are fixedly connected to the outer side of the second pawl 34 and the inner wall of the lower half ring 12, respectively. The second button 36 is slidably connected to the outer side of the lower half ring 12, and the second button 36 extends into the inner wall of the lower half ring 12. The end of the second button 36 abuts against the second pawl 34. The second knob 37 is fixedly connected to the end of the second shaft 31, and the second knob 37 is located on the outer side of the lower half ring 12.

[0037] The second adjustment part consists of ratchet 33, pawl 34, spring 35, button 36, and knob 37. It works in conjunction with the vortex elastic band 32 to adjust the resistance. When using the second resistance mechanism 3 to adjust the resistance between the upper half ring 11 and the lower half ring 12, the function and operation of the second resistance mechanism 3 are roughly the same as those of the first resistance mechanism 2, and the structure is also roughly the same. The difference is that the elastic component coil spring 22 in the first resistance mechanism 2 is replaced by the vortex elastic band 32 in the second resistance mechanism 3. When adjusting the resistance between the upper half ring 11 and the lower half ring 12, the second resistance mechanism 3 can be operated in accordance with the steps of operating the first resistance mechanism 2. Therefore, the specific usage of the second resistance mechanism 3 will not be described in detail here.

[0038] Similarly, without installing the second adjustment unit, only installing the spiral elastic band 32, different resistance requirements can be achieved by replacing the spiral elastic band 32 with different preloads. At the same time, there are two connection points between the upper half ring 11 and the lower half ring 12. Depending on the requirements, a resistance component can be installed at one connection point, and a conventional shaft connection can be used at the other connection point. This also has the function of resistance adjustment and the cost can be reduced. Alternatively, resistance components can be installed at both connection points, and selective installation can be carried out according to actual needs.

[0039] In embodiment three, the resistance component includes a third resistance mechanism 4, which is installed between the upper half ring 11 and the lower half ring 12. The third resistance mechanism 4 includes an elastic ring 41, with a stabilizing cover 42 fitted at the top and bottom of the elastic ring 41. A movable clamp 43 is fixedly connected to the outside of the stabilizing cover 42, and two movable clamps 43 are respectively fitted at the outer ends of the upper half ring 11 and the lower half ring 12. Four mounting holes 44 arranged in a rectangular array are opened on the inner side of the elastic ring 41. A telescopic rod 45 is fixedly connected between the two stabilizing covers 42, and the telescopic rod 45 passes through two adjacent mounting holes 44.

[0040] When the upper half ring 11 and the lower half ring 12 rotate closer, the elastic ring 41 will bend under pressure. The force that causes the elastic ring 41 to bend is the resistance between the upper half ring 11 and the lower half ring 12. Since the inner ring of the elastic ring 41 is elliptical, when it is necessary to adjust the resistance, the elastic ring 41 can be adjusted to a 90-degree position. When the elastic ring 41 is bent under force, the resistance will be greater, thereby achieving the purpose of adjusting the resistance between the upper half ring 11 and the lower half ring 12. Through the cooperation of the stabilizing cover 42 and the telescopic rod 45, the elastic ring 41 can always be kept vertically stressed.

[0041] It is worth mentioning that the two components that make up the telescopic rod 45, namely the inner rod and the outer tube, are detachable. During normal use, the inner rod and the outer tube are assembled together, and the telescopic rod 45 passes through the elastic ring 41. This can prevent the elastic ring 41 from tilting or detaching from the stabilizing cover 42, and can also keep the elastic ring 41 perpendicular to the force during use. When it is necessary to adjust the direction of the elastic ring 41, the inner rod can be pulled out from the outer tube, and then the elastic ring 41 can be separated from the stabilizing cover 42. After the angle is adjusted, the inner rod and the outer tube are passed through the corresponding mounting holes 44 again and the elastic ring 41 is installed between the two stabilizing covers 42. Then the inner tube and the outer tube are reassembled to form the telescopic rod 45.

[0042] In embodiment four, the resistance component includes a fourth resistance mechanism 5, which is installed between the upper half ring 11 and the lower half ring 12. The fourth resistance mechanism 5 includes a telescopic rod 51, with bases 52 fixedly connected to both ends of the telescopic rod 51. A movable clamp 53 is fixedly connected to the side of the base 52 away from the telescopic rod 51. The two movable clamps 53 are respectively sleeved on the outer ends of the upper half ring 11 and the lower half ring 12. A preload nut 55 is sleeved on the outer end of the outer tube of the telescopic rod 51, and the telescopic rod 51 and the preload nut 55 are threadedly connected. A spring 54 is sleeved on the outer end of the telescopic rod 51, and the spring 54 is located between the preload nut 55 and one of the bases 52.

[0043] When the upper half ring 11 and the lower half ring 12 rotate closer, the two bases 52 are interfered with by the movable clamp 2 53 and move closer to each other. During this period, the telescopic rod 2 51 is compressed and shortened, and the spring 3 54 is also compressed and generates elastic force. The reverse elastic force of the spring 3 54 under compression is the resistance between the upper half ring 11 and the lower half ring 12. When it is necessary to adjust the resistance, the preload nut 55 can be rotated to compress the spring 3 54 in advance to increase its initial preload force, so that the compression resistance of the spring 3 54 is greater when the upper half ring 11 and the lower half ring 12 are close together. Conversely, the preload nut 55 rotates in the opposite direction to release the elasticity of the spring 3 54 to reduce its initial preload force, so that the compression resistance of the spring 3 54 is smaller when the upper half ring 11 and the lower half ring 12 are close together, thereby achieving the purpose of adjusting the resistance when using the exerciser body 1.

[0044] The aforementioned third resistance mechanism 4 and fourth resistance mechanism 5 can be used in combination with the first resistance mechanism 2 or the second resistance mechanism 3, such as by simultaneously installing the first resistance mechanism 2 and the third resistance mechanism 4, or the first resistance mechanism 2 and the fourth resistance mechanism 5, or the second resistance mechanism 3 and the third resistance mechanism 4, or the second resistance mechanism 3 and the fourth resistance mechanism 5 on the same exerciser body 1.

[0045] The four embodiments described above correspond to four style embodiments of style one, style two, style three, and style four, respectively. Figure 13 These are schematic diagrams illustrating the specific usage effects of Style 1 or Style 2.
