Description

Technical Field

[0001] This invention relates to the field of tension training equipment technology, and more specifically, to a multifunctional low-position tension training equipment. Background Technology

[0002] A resistance trainer is a fitness machine that transmits resistance through steel cables. Traditional low-position resistance trainers provide vertical pulleys via a fixed pulley system and are primarily used for basic movements such as single-arm rows (training the latissimus dorsi / biceps) and biceps curls. Users stand in front of the machine, gripping the D-handles connected to the weight cables to perform single-plane movements. Weight adjustment is achieved by manually inserting and removing weight plates. Currently, low-position resistance trainers are typically found in gyms for users.

[0003] Regarding the aforementioned technologies, existing low-position resistance trainers, while capable of performing corresponding training movements, suffer from limited functionality due to their structural constraints. They offer a relatively limited range of training methods and movements, failing to support compound movements like squats and deadlifts, let alone multi-angle training such as lateral raises. Furthermore, different training methods require different weight adjustments. When users connect the equipment via a belt (e.g., for squats), the belt restricts its position, necessitating a break in training, belt removal, and walking to the weight adjustment pin (each adjustment takes ≥60 seconds). Frequent adjustments disrupt the continuity of training and negatively impact the overall workout. Therefore, a multifunctional low-position resistance trainer is proposed. Summary of the Invention

[0004] To address the above problems, this invention provides a multifunctional low-position tension training device, employing the following technical solution:

One end of each of the two linkage arms 314 is hinged to the outer surface of the column 316. The engaging assembly 310 also includes a square sleeve 319 fixedly connected to one side of the inner wall of the engaging plate 311. An extension rod 3110 is movably connected inside the square sleeve 319. One end of the extension rod 3110 extends to the outside of the engaging plate 311. An attractive magnetic block 3113 and a repulsive magnetic block 3112 are fixedly connected to the outer surface of the extension rod 3110. The attractive magnetic block 3113 is magnetically connected to the magnetic block 317. The other end of the extension rod 3110 is fixedly connected to the inner wall of the engaging plate 311 by a first spring 318. Two springs 3111, a connecting groove 3114 is provided on one side of the front end face of the snap-fit ​​plate 311, the limiting component 320 includes a limiting frame 321 fixedly connected to the training main frame 110, the limiting frame 321 has a plurality of fixing holes 322 equidistantly arranged in a straight line, the height of the plurality of fixing holes 322 respectively corresponding to two snap-fit ​​holes 260, the manual component 330 includes a manual arm 331 slidably connected inside the limiting frame 321, a hollow push rod 332 is movably connected between the two sides of the manual arm 331, the hollow push rod 332 is close to the rear end face of the manual arm 331, an inner wheel 333 is rotatably connected between the top and bottom of the inner wall of the hollow push rod 332, and a third spring is fixedly connected between one end of the hollow push rod 332 and one side of the manual arm 331. Spring 334, hollow push rod 332 and extension rod 3110 are adapted to each other. The manual assembly 330 also includes a booster rack rod 335 movably connected inside the manual arm 331.

[0041] Pulling the control handle 339 with the hand grip 3310 will cause the gear 338 to rotate and push the booster rack rod 335. At this time, the insertion rod 337 will retract from one of the fixing holes 322 and insert into the connecting slot 3114. Simultaneously, the booster rack rod 335 will push the inner wheel 333, causing the inner wheel 333 to push the hollow push rod 332. The hollow push rod 332 will push the extension rod 3110. The movement of the extension rod 3110 will cause the magnetic block 317 to separate from the attracting magnetic block 3113, and the repulsive magnetic block 3112 to repel the magnetic block 317, thereby pushing the mounting column 316 to move. At this time, the two linkage arms 314 will push the two connecting plates 313, which will drive the two locking rods 312. Remove the two locking holes 260, lift the lever 3310 to raise the locking plate 311, and after it rises to the corresponding position, gradually release the control handle 339. At this time, the magnetic block 3113 resets and reconnects with the magnetic block 317. The locking rod 312 will first connect with the other two locking holes 260. Then, the insertion rod 337 will disconnect from the connecting groove 3114 and insert into another fixing hole 322. At the same time, the tension winder will wind up the connecting rope 220 to prevent it from becoming loose. Then, pull the connecting rope 220 through the connecting chain 270 to pull out the connecting rope 220 wound by the tension winder.

The single-hand auxiliary handle 163 and the double-hand auxiliary handle 166 are each threaded with a first fixing bolt 165. The two first fixing bolts 165 extend into the interior of two of the first locking holes 164 respectively.

[0045] By removing the two first fixing bolts 165, the positions of the two-hand auxiliary handle 166 and the one-hand auxiliary handle 163 can be rotated and adjusted. After adjustment, the designated first fixing bolt 165 can be turned into the designated first locking hole 164 to complete the fixation. The two-hand auxiliary handle 166 and the one-hand auxiliary handle 163 can provide assistance during training, and the trainee can hold them as needed.

[0046] The main module 100 also includes a hoisting plate 120 fixedly connected to one side of the training main frame 110. Three hanging rods 180 are fixedly connected to one side of the hoisting plate 120. Each of the three hanging rods 180 has a buckle 170 on its outer surface. One end of each of the three buckles 170 is connected to a single-hand grip 150, a double-hand grip 140, and a waist belt 130, respectively.

[0047] Choose one of the following: belt 130, two-handed grip 140, and one-handed grip 150, and then connect it to the connecting chain 270 via buckle 170.

[0048] The implementation principle of this invention is as follows: When using this trainer, first stand on the main training frame 110, and select one of the following: waist belt 130, two-handed grips 140, and one-handed grip 150. Then connect it to the connecting chain 270 through the buckle 170. When in use, pull the connecting rope 220, which will pull the locking assembly 310 through the tension winding device, thereby lifting the corresponding number of counterweights 230 to achieve the training effect. The one-handed grip 150 can be used for single-arm rowing training, targeting the latissimus dorsi, posterior deltoid, and biceps brachii. Stand with one hand holding the one-handed grip 150 and perform back contraction and pulling. The waist belt 130 can be used for weighted squat training, targeting the gluteus maximus, quadriceps, and hamstrings. Place both feet firmly on the pedals. The machine allows for squatting, and with both hands gripping handles 140, it can be used for deadlifts, biceps curls, and lateral raises. Deadlifts target the glutes, lower back, and hamstrings. Grips 140 simulate a free deadlift. Biceps curls target the biceps. Grips 140 involve curling the elbows upwards to focus on the upper arms. Lateral raises target the anterior deltoid. This machine is suitable for improving anterior shoulder strength and shoulder shape, allowing for multiple training options and enhancing its overall functionality. The direction can be adjusted by lifting the second fixing bolt 253 and then pushing the cable traction bracket 254. Once the direction is confirmed, the second fixing bolt 253 can be inserted into another second locking hole. Between 252 and the rope traction bracket 254, the rope traction bracket 254 is fixed, thereby changing the position of the connecting chain 270 to adapt to different training methods. By removing the two first fixing bolts 165, the positions of the two-handed auxiliary handle 166 and the one-handed auxiliary handle 163 can be rotated and adjusted. After adjustment, the designated first fixing bolt 165 is turned into the designated first locking hole 164 to complete the fixation. The two-handed auxiliary handle 166 and the one-handed auxiliary handle 163 can provide assistance during training. The trainee can hold them as needed. When it is necessary to adjust the training weight during training while wearing the waist belt 130, the staff first holds the handle 3310 and pulls the control handle 339. The control handle 339 will drive the gear 338 to rotate. Pushing the rack and pinion rod 335 causes the insertion rod 337 to retract from one of the fixing holes 322 and insert into the connecting slot 3114. Simultaneously, the rack and pinion rod 335 pushes the inner wheel 333, causing the inner wheel 333 to push the hollow push rod 332. The hollow push rod 332 pushes the extension rod 3110, causing the extension rod 3110 to move and causing the magnetic block 317 to separate from the attracting magnetic block 3113. The repulsive magnetic block 3112 repels the magnetic block 317, thereby pushing the mounting column 316 to move. At this time, the two linkage arms 314 push the two connecting plates 313, which will cause the two locking rods 312 to retract from the two locking holes 260. By lifting the grip rod 3310, the locking plate 311 rises. After rising to the corresponding position, the control handle 339 is gradually released.At this point, the magnetic block 3113 resets and reconnects with the magnetic block 317. The locking rod 312 will first connect with the other two locking holes 260. Subsequently, the insertion rod 337 disconnects from the connecting slot 3114 and inserts into another fixing hole 322. Simultaneously, the tension winder winds up the connecting rope 220 to prevent it from becoming loose. Then, the connecting chain 270 pulls the connecting rope 220 to pull out the winder-wound rope 220. Connecting the buckle 170 to the other positions of the connecting chain 270 completes the entire operation.
