Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment, and in particular to a multifunctional resistance band. Background Technology
[0002] A resistance band is a home fitness exercise device that works the biceps brachii by bending the arms. The resistance is provided by elastic bands. Existing resistance bands can vary the resistance by changing the number of elastic bands, thus meeting the training needs of different people. To avoid muscle over-fatigue, users need to silently count the number of stretches and rest immediately after reaching the planned number. Because existing resistance bands do not have a counting function, counting by heart can easily lead to errors when exercising frequently, potentially affecting the fitness results.

[0022] 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.
[0023] This utility model proposes a multifunctional tensioner, see reference. Figure 1 , 3 The system includes a counting connector 1 and a positioning connector 2. Both the counting connector 1 and the positioning connector 2 have several positioning posts 11 on their inner ends. The counting connector 1 has a sliding cavity 12 inside. The two ends of the sliding cavity 12 have openings that communicate with the outside. The bottom of the sliding cavity 12 has a Hall sensor 13. The top of the sliding cavity 12 has a display screen 14 and a circuit board 15. The display screen 14 is signal-connected to the Hall sensor 13. The positioning connector 2 has a positioning cavity 21 inside.
[0024] Two handles 3 are connected to the counting connector 1 and the positioning connector 2 respectively. (See reference) Figure 2 The grip 3 is provided with a limiting section 31. One of the limiting sections 31 extends into the sliding cavity 12 through an opening and is slidably connected to the sliding cavity 12. The inner side of the limiting section 31 is provided with a positioning shaft 32. A return spring 33 is sleeved on the positioning shaft 32. The two ends of the return spring 33 abut against the sliding cavity 12 and the limiting section 31, respectively. A magnet 34 is provided on the limiting section 31. The other limiting section 31 is inserted and fixed in the positioning cavity 21.
[0025] Several elastic ropes 4 are provided, and positioning holes 41 are provided at both ends of the elastic ropes 4. The positioning pins 11 are inserted into the positioning holes 41 to realize the connection between the elastic ropes 4 and the counting connecting seat 1 and the positioning connecting seat 2. The user can increase or decrease the number of elastic ropes according to the usage requirements.
[0026] When using this resistance band, the user holds both handles 3 and pulls them to the sides. Under the pull, the limiting section 31 slides outward in the sliding cavity 12. After the user releases the force, the return spring 33 pushes the limiting section 31 to slide inward in the sliding cavity 12. This is one complete displacement. During this process, the magnet 34 passes back and forth above the Hall sensor 13, generating a displacement signal that is sent to the circuit board 15. After processing, the signal is displayed on the display screen 14. One complete displacement corresponds to a count of one. The user can know the number of stretches through the numbers on the display screen 14, thus accurately completing the exercise task and ensuring the fitness effect.
[0027] See Figure 2 , 3The counting connector 1 includes an upper shell 16 and a lower shell 17 that are spliced together. The sliding cavity 12 is formed between the upper shell 16 and the lower shell 17. The upper shell 16 is provided with an opening 161, and the display screen 14 is fixed in the opening 161.
[0028] See Figure 3 The positioning post 11 is located in the upper shell 16, and the positioning post 11 is provided with a plug hole 111. The lower shell 17 is provided with a plug shaft 171. In the combined state, the plug shaft 171 is inserted into the plug hole 111.
[0029] See Figure 2 The sliding cavity 12 is provided with a guide groove 121, and the reset spring 33 is provided in the guide groove 121 to prevent the reset spring 33 from shifting left and right and affecting the return effect of the limiting section 31.
[0030] See Figure 2 , 3 The opening is provided with a limiting piece 122, and the limiting segment 31 is provided with limiting grooves 311 on both sides. The limiting piece 122 abuts against the limiting grooves 311 to prevent the limiting segment 31 from coming out of the sliding cavity 12.
[0031] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
