Abstract
Description
Technical Field
[0001] This utility model relates to the field of exercise equipment, and in particular to a circular arm strength training device. Background Technology
[0002] The speed arm machine is primarily used to train the arms and shoulders. It works by combining speed and force to strengthen the muscles in the arms and shoulders.
[0003] Patent publication number CN204121675U shows a structure for an arm exerciser, including a main body, two turntables, two bearing assemblies, two elastic blocks, a rear clamping plate, a front clamping plate, and an adjustment knob. The main body has two outer rings, and the two turntables are rotatably mounted on the two outer rings. The two bearing assemblies are located between the two turntables and the two outer rings. The two elastic blocks have elastic deformation force and are attached to the main body. The rear clamping plate is located on the rear side of the two elastic blocks, with a central screw extending through to the front side of the main body. Each of the two sides of the rear clamping plate has a rear damping plate. The front clamping plate is located on the front side of the two elastic blocks, with a central through hole. Each of the two sides of the front clamping plate has a front damping plate. The adjustment knob can be screwed onto the end of the screw. Tightening the adjustment knob increases rotational resistance, and loosening the adjustment knob reduces rotational resistance. However, the structure of this prior art is not simple enough, and its usage is relatively complicated. Utility Model Content
[0004] To address the aforementioned issues, this invention proposes a wraparound arm strength trainer, which solves the problems of an insufficiently simple arm strength trainer structure and complex usage.
[0005] The technical solution adopted by this utility model is: a ring-shaped arm strength trainer, including a ring shell, a handle on the ring shell, a rotating ring rotatably connected to the ring shell, at least three rotating parts inside the ring shell, the inner side of the rotating ring contacting the rotating parts, a connecting belt connected to the rotating ring, and a counterweight connected to the connecting belt.
[0006] Through the above technical solution, the main structure of this utility model includes an annular shell, a rotating ring, a rotating component, a connecting belt, and a counterweight. The user only needs to hold the handle and shake his arm to make the counterweight swing. The counterweight will carry the connecting belt and the rotating ring to make a circular motion. The rotating component is driven by the rotating ring to rotate together, reducing the friction when the rotating ring rotates, making its rotation smoother. The faster the rotation speed, the better the exercise effect on the arm, and the simpler the way to use it.
[0007] Furthermore, the rotating component has annular protrusions on both sides, and the rotating ring has an annular inner end portion, which is located between the two annular protrusions.
[0008] Through the above technical solution, the annular protrusions on both sides of the rotating component limit the inner end of the annular ring on the rotating ring. During exercise, this prevents the rotating ring and the rotating component from shaking, which would lead to uneven exercise and avoid safety hazards.
[0009] Furthermore, the annular shell includes an upper shell and a lower shell. The upper shell is provided with a first limiting part, and the lower shell is provided with a second limiting part. The rotating member is located between the first limiting part and the second limiting part, and the first limiting part and the second limiting part limit the rotating member.
[0010] Through the above technical solution, the first and second limiting parts limit the rotating part, preventing the rotating part from shaking inside the annular shell, which would cause the exercise to be unsmooth and avoid safety hazards.
[0011] Furthermore, the rotating component includes a rotating block, and two rotating blocks constitute the rotating component. The rotating block has a mounting hole, and a connecting post is installed between the upper housing and the lower housing, with the connecting post passing through the mounting hole.
[0012] With the above technical solution, two rotating blocks form a rotating component, and the two rotating components are respectively installed from the upper shell and the lower shell of the trainer onto the connecting column, making the assembly of the entire trainer more convenient.
[0013] Furthermore, the rotating block is provided with an inclined conical section, and the rotating ring is provided with a corresponding inclined conical surface, the diameter of the inclined conical section gradually increasing towards the annular protrusion.
[0014] With the above technical solution, when the rotating block is installed, the inclined cone section will slide along the inclined cone surface, and the inclined cone surface will avoid the inclined cone section, making the installation of the rotating block simpler.
[0015] Furthermore, the upper housing is provided with a first annular end, the lower housing is provided with a second annular end, and both sides of the rotating ring are provided with third annular ends. The first annular end is in clearance fit with the adjacent third annular end, and the second annular end is in clearance fit with the adjacent third annular end.
[0016] With the above technical solution, the first annular end does not contact the third annular end, and the second annular end does not contact the third annular end, ensuring that the rotating ring can rotate smoothly and preventing the rotating ring from shifting up and down, causing friction and collision, thus increasing its service life.
[0017] Furthermore, an annular groove is provided on the rotating ring, and the annular groove is located between the inner end of the ring and the third annular end.
[0018] The above technical solution involves creating an annular groove on the rotating ring, which reduces the amount of material used, making the whole device lighter and reducing material costs.
[0019] Furthermore, the rotating ring is provided with a protrusion, and the protrusion has a plurality of adjustment holes, and the connecting band is connected to the adjustment holes.
[0020] By adjusting the connection between the connecting belt and each hole, and increasing or decreasing the distance between the counterweight and the handle, the length of the lever arm can be adjusted, requiring less or more force for training and changing the training intensity of the trainer.

[0032] See Figure 1 , Figure 2 A ring-shaped arm strength trainer includes an annular shell 1, a handle 101 on the annular shell 1, a rotating ring 2 rotatably connected to the annular shell 1, at least three rotating parts 3 inside the annular shell 1, the inner side of the rotating ring 2 in contact with the rotating parts 3, a connecting belt 4 connected to the rotating ring 2, and a counterweight 5 connected to the connecting belt 4.
[0033] The main structure of this utility model consists of an annular shell 1, a rotating ring 2, a rotating component 3, a connecting belt 4, and a counterweight 5. The user only needs to hold the handle 101 and shake his arm to make the counterweight 5 swing. The counterweight 5 will carry the connecting belt 4 and the rotating ring 2 to make a circular motion together. The rotating component 3 is driven by the rotating ring 2 to rotate together, reducing the friction when the rotating ring 2 rotates, making its rotation smoother. The faster the rotation speed, the better the exercise effect on the arm. The method of use is also simpler.
[0034] The preferred number of rotating parts 3 is 6.
[0035] See Figure 2 , Figure 4The rotating part 3 has annular protrusions 302 on both sides, and the rotating ring 2 has annular inner end 201, which is located between the two annular protrusions 302.
[0036] The annular protrusions 302 on both sides of the rotating component 3 limit the annular inner end 201 on the rotating ring 2. During exercise, this prevents the rotating ring 2 and the rotating component 3 from shaking, which would cause the exercise to be unsmooth and avoid safety hazards.
[0037] See Figure 2 The annular shell 1 includes an upper shell 102 and a lower shell 103. The upper shell 102 is provided with a first limiting part 1021, and the lower shell 103 is provided with a second limiting part 1031. The rotating member 3 is located between the first limiting part 1021 and the second limiting part 1031. The first limiting part 1021 and the second limiting part 1031 limit the rotating member 3.
[0038] The first limiting part 1021 and the second limiting part 1031 limit the rotating part 3 to prevent the rotating part 3 from shaking inside the annular shell 1, which would cause the exercise to be unsmooth and avoid safety hazards.
[0039] See Figure 2 , Figure 4 The rotating component 3 includes a rotating block 301. Two rotating blocks 301 form the rotating component 3. The rotating block 301 has a mounting hole 3011. A connecting post 6 is installed between the upper housing 102 and the lower housing 103. The connecting post 6 passes through the mounting hole 3011.
[0040] Two rotating blocks 301 form a rotating component 3. The two rotating components 3 are installed from the upper shell 102 and the lower shell 103 of the trainer to the connecting column 6, making the assembly of the entire trainer more convenient.
[0041] See Figures 2-4 The rotating block 301 is provided with a tapered section 3012, and the rotating ring 2 is provided with a corresponding tapered surface 202. The diameter of the tapered section 3012 gradually increases towards the annular protrusion 302.
[0042] The inclined cone segment 3012 will slide along the inclined cone surface 202, and the inclined cone surface 202 will avoid the inclined cone segment 3012, making the installation of the rotating block 301 simpler.
[0043] See Figure 2 The upper housing 102 is provided with a first annular end 1022, the lower housing 103 is provided with a second annular end 1032, and both sides of the rotating ring 2 are provided with a third annular end 203. The first annular end 1022 is in clearance fit with the adjacent third annular end 203, and the second annular end 1032 is in clearance fit with the adjacent third annular end 203.
[0044] The first annular end 1022 does not contact the third annular end 203, and the second annular end 1032 does not contact the third annular end 203, ensuring that the rotating ring 2 can rotate smoothly and preventing the rotating ring 2 from shifting up and down, causing friction and collision, thus increasing its service life.
[0045] See Figure 2 , Figure 3 The rotating ring 2 has an annular groove 204, which is located between the inner end 201 of the ring and the third annular end 203.
[0046] The rotating ring 2 has an annular groove 204, which reduces the amount of material used, making the whole unit lighter and reducing material costs.
[0047] See Figures 1-3 The rotating ring 2 is provided with a protrusion 205, and the protrusion 205 is provided with multiple adjustment holes 2051. The connecting belt 4 is connected to the adjustment holes 2051.
[0048] Adjusting the connection between the connecting strap 4 and each hole, increasing or decreasing the distance between the counterweight 5 and the grip 101, can adjust the length of the lever arm, requiring less or more force for training and changing the training intensity of the trainer.
[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
