Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0062] refer to Figure 1-13 A specific embodiment of the present invention provides a multifunctional double lever arm training machine, comprising:

[0063] Base 1;

[0064] The main storage compartment 13 is located inside the base 1;

[0065] The first end of the column 8 is slidably connected to the bottom surface of the main storage compartment 13 via the first slider 39, and is restricted to the end of the main storage compartment 13 by the positioning unit. The first end of the column 8 is rotatably connected to the first slider 39, and the rotation angle is restricted by the first angle limiting unit.

[0066] The second ends of the two sets of lever arms 10 are rotatably connected to the second ends of the column 8, and the horizontal and vertical rotation angles are limited by the second angle limiting unit respectively.

[0067] The second slider 29, the counterweight plate 7 is detachably connected to the second slider 29 and is slidably connected to the column 8 via the second slider 29, and the first end of the lever arm 10 is connected to the second slider 29 via the training rope 20.

[0068] Existing fitness equipment typically has limited functionality, making it difficult to meet users' training needs for different muscle groups. Furthermore, many pieces of equipment are inconvenient to store and use, impacting the user's training experience. In this application, the main function of the main storage compartment 13 is to store the column 8 and the lever arm 10. The positioning unit primarily confines the column 8 within the main storage compartment 13, preventing it from wobbling or bumping during transport. The first angle limiting unit primarily limits the angle of the column 8 when unfolded or retracted, facilitating adjustment of different training angles and easy opening or storage. The second angle limiting unit primarily limits the horizontal and vertical angles between the lever arm 10 and the column 8, providing different training modes through the two sets of lever arms 10, effectively enhancing training results. By uniformly pulling or releasing the first end of the lever arm 10, the weight plate 7 slides, thus completing reciprocating training. Overall, this application allows for angle adjustment as needed, enabling multiple training modes, facilitating the training of different muscle groups, and is also convenient to store and use.

[0069] Further optimizations to the plan include:

[0070] Locking ball 19, the first end of training rope 20 passes through the first end of lever arm 10 and is fixedly connected to locking ball 19;

[0071] Gantry handle 11, the T-shaped fixing head 17 on gantry handle 11 is detachably connected to locking ball 19;

[0072] The first groove 14 is located on the side of the locking ball 19 away from the training rope 20;

[0073] The second groove 18 is formed inside the locking ball 19 and communicates with the first groove 14. The second groove 18 is perpendicular to the first groove 14, and the T-shaped fixing head 17 is adapted to fit inside the second groove 18.

[0074] The main function of the locking ball 19 is to facilitate the connection between the gantry handle 11 and the training rope 20, so that by pulling the training rope 20, the counterweight plate 7 can be driven to complete the training. The length and width of the first groove 14 and the second groove 18 are adapted to the T-shaped fixing head 17. The T-shaped fixing head 17 extends from the first groove 14 into the locking ball 19, and after being manually rotated 90°, it is adapted into the second groove 18. During the pulling process, the T-shaped fixing head 17 is confined in the second groove 18 to prevent the gantry handle 11 from becoming loose from the locking ball 19, thus ensuring safe training.

[0075] Further optimizations to the plan include:

[0076] The first spring 16 abuts against the inner wall of the locking ball 19 and the T-shaped fixing head 17;

[0077] The top cover 15 is slidably connected within the locking ball 19 and abuts against the first spring 16 and the T-shaped fixing head 17.

[0078] When the T-shaped fixing head 17 is manually inserted into the first groove 14, it abuts against the top cover 15, overcomes the elastic force of the first spring 16, rotates 90°, and is pushed into the second groove 18 by the first spring 16. The main function of the first spring 16 is to abut the top cover 15 against the T-shaped fixing head 17 and restrict the T-shaped fixing head 17 in the second groove 18. When not training, it can also ensure a stable connection between the gantry handle 11 and the locking ball 19.

[0079] The scheme has been further optimized, and the second angle limiting unit includes:

[0080] Rotary seat 9 is horizontally rotatably connected to the second end of column 8, and the second end of lever arm 10 is vertically rotatably connected to rotary seat 9;

[0081] A horizontal angle limiting component is installed at the connection between the rotating base 9 and the column 8;

[0082] The upper and lower angle limiting components are located at the connection between the rotating seat 9 and the lever arm 10.

[0083] The main function of the horizontal angle limiting component is to facilitate adjustment and limit the position of the lever arm 10 in the horizontal plane; the main function of the vertical angle limiting component is to facilitate adjustment and limit the position of the lever arm 10 and the column 8 in the vertical plane; through the above adjustments, multi-angle training modes can be met, so as to achieve training effects on different muscle groups.

[0084] Further optimization of the solution includes the following upper and lower angle limiting components:

[0085] Fixed gear 21 is fixedly connected to the second end of lever arm 10;

[0086] Positioning teeth 22 are slidably connected in the rotating seat 9 and are set to correspond to the teeth on the fixed gear 21;

[0087] The sixth spring 27 abuts against the inner wall of the rotating seat 9 on the side of the positioning tooth 22 away from the fixed gear 21.

[0088] When the lever arm 10 and the column 8 are moved out of the main storage compartment 13, the lever arm 10 and the column 8 are parallel and fitted together, and the positioning teeth 22 are adapted between the adjacent teeth of the fixed gear 21. When it is necessary to unfold the lever arm 10 and the column 8, manually move the positioning teeth 22 so that the positioning teeth 22 overcome the elastic force of the sixth spring 27 and disengage from the fixed gear 21. At the same time, manually rotate the lever arm 10 so that the first end of the lever arm 10 gradually moves away from the column 8. When rotated to the appropriate position, release the positioning teeth 22. Under the elastic force of the sixth spring 27, the positioning teeth 22 are pushed into the corresponding adjacent teeth on the fixed gear 21 to realize the vertical angle adjustment between the lever arm 10 and the column 8.

[0089] Further optimizations to the plan include:

[0090] Adjustment button 24, the first end of adjustment button 24 is rotatably connected to the rotating base 9;

[0091] Link 23 is pivotally connected between the second end of the adjustment button 24 and the positioning tooth 22.

[0092] Pressing the adjustment button 24 causes the positioning tooth 22 to slide within the rotating seat 9 via the connecting rod 23, overcoming the elastic force of the sixth spring 27. At the same time, the positioning tooth 22 disengages from the fixed gear 21. After releasing the adjustment button 24, under the elastic force of the sixth spring 27, the positioning tooth 22 pushes into the corresponding adjacent teeth on the fixed gear 21, thereby realizing the adjustment of the vertical angle between the lever arm 10 and the column 8.

[0093] Further optimization of the solution includes the following horizontal angle limiting components:

[0094] Second positioning groove 28, a plurality of second positioning grooves 28 are circumferentially formed on the bottom surface of the rotating seat 9;

[0095] The second positioning pin 25 passes through the second end of the column 8 and extends into one of the sets of second positioning grooves 28;

[0096] The second spring 26 abuts against the upper end of the second locating pin 25 and the top of the column 8.

[0097] When the lever arm 10 and the column 8 are moved out of the main storage compartment 13, and the lever arm 10 has completed the vertical angle adjustment, the two sets of lever arms 10 are located directly above the base 1. At this time, the second positioning pin 25 extends into one of the second positioning grooves 28 under the elastic force of the second spring 26. When adjusting the horizontal angle between the lever arm 10 and the column 8 as needed, manually move the second positioning pin 25 to overcome the elastic force of the second spring 26, so that the second positioning pin 25 is disengaged from the second positioning groove 28. Manually rotate the lever arm 10 until it reaches the designated position, then release the second positioning pin 25. Under the elastic force of the second spring 26, the second positioning pin 25 is pushed into the corresponding second positioning groove 28, completing the horizontal angle limit.

[0098] Further optimizations to the plan include:

[0099] Sleeve rod 36, the first end of sleeve rod 36 is inserted into the second slider 29, and several counterweight discs 7 are sleeved on sleeve rod 36;

[0100] Disassemble connecting rod 35, and sleeve rod 36 is axially sleeved on disassemble connecting rod 35;

[0101] The first end of at least one set of sliding columns 31 radially passes through the side wall of the sleeve rod 36 and is axially contacted with the inner side wall of the second slider 29, and the second end of the sliding column 31 is in contact with the second end of the disassembly connecting rod 35.

[0102] When the lever arm 10 and the column 8 are removed from the main storage compartment 13 and unfolded as needed, the first end of the sleeve rod 36 is inserted into the second slider 29. By sliding the connecting rod 35 inside the sleeve rod 36, the sliding column 31 is pushed out of the side wall of the sleeve rod 36, so that the sliding column 31 is axially contacted with the inner side wall of the second slider 29, so that the sleeve rod 36 cannot be pulled out from the second slider 29. Then, several counterweight plates 7 are fitted onto the sleeve rod 36, and all the counterweight plates 7 are limited on the sleeve rod 36 through the quick-release connector 37 to prevent them from falling off.

[0103] Further optimizations to the plan include:

[0104] The second end of the variable diameter connecting rod 33 and the disassembly connecting rod 35 is configured as the variable diameter connecting rod 33. The second end of the sliding column 31 is in contact with the circumferential side of the large diameter end of the variable diameter connecting rod 33. The connection between the variable diameter connecting rod 33 and the disassembly connecting rod 35 is the small diameter end.

[0105] The third spring 32 abuts against the inner wall of the second slider 29 and the large diameter end of the variable diameter connecting rod 33.

[0106] Under the elastic force of the third spring 32, the disassembly connecting rod 35 abuts against the end of the sleeve rod 36 connected to the quick-release connector 37. At this time, the second end of the sliding column 31 contacts the circumference of the large diameter end of the variable diameter connecting rod 33, and the sleeve rod 36 is locked in the second slider 29. When it is necessary to store the lever arm 10 and the column 8, after restoring the lever arm 10 and the column 8 to their previous state or before restoring them, open the quick-release connector 37 and remove the counterweight plate 7 in sequence. It can be installed in the kettlebell. A kettlebell of a certain weight is used for training. After the counterweight plate 7 is removed, the disassembly link 35 is pressed towards the second slider 29, while the third spring 32 is compressed. When the small diameter end of the variable diameter link 33 corresponds to the slide column 31, the centripetal direction of the slide column 31 is no longer constrained. When the sleeve rod 36 is pulled out from the second slider 29, all the slide columns 31 are squeezed into the sleeve rod 36. At this point, the disassembly of the counterweight plate 7 and the sleeve rod 36 is completed. Next, the lever arm 10 and the column 8 are stored.

[0107] Further optimizations to the plan include:

[0108] Locking block 30, which is axially sleeved on the first end of sleeve rod 36, and the first end of sliding pin 31 that passes radially through the side wall of sleeve rod 36 extends into locking block 30;

[0109] The third groove 38 is formed on the column 8, and the first locking block on the locking block 30 is adapted to the third groove 38.

[0110] The main function of the locking block 30 is to restrict the second slider 29 on the column 8, that is, the starting position of the second slider 29. The first locking block on the locking block 30 is located in the third groove 38. When the sliding column 31 is pushed into the locking block 30 by the large diameter end of the variable diameter connecting rod 33, the locking block 30 and the sleeve rod 36 are relatively fixed. When the sleeve rod 36 is pushed axially, the locking block 30 is disengaged from the third groove 38. Then the second slider 29 and the counterweight plate 7 on the second slider 29 can be pulled by the gantry handle 11 and the training rope 20.

[0111] The scheme has been further optimized, and the first angle limiting unit includes:

[0112] A hollow central rotating shaft 6 is axially fixed through the first end of the column 8 and is rotatably connected to the first slider 39.

[0113] First positioning groove 40, a plurality of first positioning grooves 40 are radially opened at both ends of the hollow central rotating shaft 6;

[0114] The first positioning pin 4 has its first end passing through the first slider 39 and extending into one of the first positioning grooves 40.

[0115] The mounting hole is located inside the first slider 39, and the first end of the first positioning pin 4 passes through the mounting hole.

[0116] The fourth spring 42 is located inside the mounting hole and abuts against the first end of the first locating pin 4 and the inner wall of the mounting hole.

[0117] When the column 8 is in the retracted state, the first end of the first positioning pin 4 passes through the first slider 39 and abuts against the side wall of the hollow central rotating shaft 6 under the elastic force of the fourth spring 42. When the column 8 is unfolded, the first positioning groove 40 rotates with the hollow central rotating shaft 6 until the first positioning groove 40 corresponds to the first positioning pin 4, and the first positioning pin 4 is pushed into the first positioning groove 40 by the elastic force. By manually moving the first positioning pin 4, the first positioning pin 4 is disengaged from the first positioning groove 40. When the column 8 rotates to the designated position, the first positioning pin 4 is released, and the first positioning pin 4 is matched with the corresponding set of first positioning grooves 40, thus completing the angle adjustment of the column 8. Retraction process: the first positioning pin 4 is disengaged from the first positioning groove 40 until the column 8 returns to the retracted state.

[0118] The scheme has been further optimized, and the positioning unit includes:

[0119] Handle slider 46 is slidably connected to the bottom of the entrance / exit of the main storage compartment 13;

[0120] Fixed blocks 45, several fixed blocks 45 are fixedly connected to the bottom four corners of the main storage compartment 13;

[0121] The second locking block 44 is slidably connected between the fixed block 45 and the bottom of the main storage compartment 13, and is set in correspondence with the first slider 39. All the second locking blocks 44 are fixedly connected to the handle slider 46 by the locking pull rope 43 respectively.

[0122] The fifth spring 47 abuts against the second locking block 44 on the side near the locking rope 43 between it and the fixing block 45.

[0123] In the folded state, the first slider 39 is located inside the main storage compartment 13 and is blocked by one of the second locking blocks 44 to prevent the first slider 39 and the column 8 from shifting. When the column 8 needs to be unfolded, the handle slider 46 is manually pulled to overcome all the fifth springs 47 and bring all the second locking blocks 44 into the fixing block 45, at which time the first slider 39 is released. When the first slider 39 slides with the column 8 to the entrance and exit of the main storage compartment 13, the second locking blocks 44 are released and locked on the side of the first slider 39 near the main storage compartment 13, limiting the first slider 39 and the column 8 at the entrance and exit of the main storage compartment 13. Each of the second locking blocks 44 has a slope on one side. The slope is located at the storage position (storage state position) and the unfolded position (unfolded state position) of the second locking block 44 away from the first slider 39. When the first slider 39 contacts the second locking block 44 during movement, the slope squeezes the second locking block 44, driving the second locking block 44 to retract. When the first slider 39 passes the second locking block 44, the second locking block 44 pops out, thus achieving the purpose of the second locking block 44 limiting the first slider 39.

[0124] Further optimizations to the plan include:

[0125] First roller 3, several first rollers 3 are rotatably connected to the first end of base 1;

[0126] Handle 12 is installed at the second end of the base 1.

[0127] When the machine is in its stored state, the second end of the base 1 can be lifted by the handle 12, and the first roller 3 will contact the bottom surface, allowing the entire training machine to be moved flexibly.

[0128] Further optimizations to the plan include:

[0129] Second rollers 48, several second rollers 48 are rotatably connected to the bottom of the main storage compartment 13, and are respectively arranged along the sliding direction of the column 8.

[0130] The main function of the second roller 48 is to make it easier and less strenuous when manually driving the column 8 to slide within the main storage compartment 13.

[0131] Further optimizations to the plan include:

[0132] Cover plate 2 is rotatably connected to the entrance and exit of the main storage compartment 13.

[0133] When in the storage state, the cover 2 seals the entrance and exit of the main storage compartment 13, providing a certain degree of protection; when it needs to be unfolded, the cover 2 should be opened in advance.

[0134] Alternatively, one of the aforementioned lever arms 10 can be replaced with a grip connecting rod 41. The grip connecting rod 41 is inserted into the column 8 and can be fixed with bolts or left unfixed, facilitating one-handed training by holding the grip connecting rod 41 with one hand.

[0135] Further optimizations to the plan include:

[0136] Steering head 51, the first end of steering head 51 extends into the first end of lever arm 10 and is rotatably connected to lever arm 10 through bearing 50, the first end of training rope 20 passes out of steering head 51 and is fixedly connected to locking ball 19;

[0137] Pulley 49, two sets of pulleys 49 are rotatably connected in the steering head 51 and symmetrically contact the two sides of the first end of the training rope 20.
