Description

Technical Field

[0001] The invention relates to the technical field of swimming training equipment, in particular to a swimming training resistance device. Background Art

[0002] Swimming training resistance equipment is mainly used to improve swimming resistance and training effect. These equipments increase the forward resistance of athletes in the water, help them to perform load training under different resistance conditions, and thus improve swimming skills and physical fitness. Among them, the swimming resistance parachute is a typical resistance equipment. It is connected to the athlete's waist through a fixed belt. When swimming, the water bag is fully opened to provide stable resistance and help practice swimming skills.

[0003] The problems with existing swimming resistance parachutes mainly include: inconvenient resistance adjustment, lack of real-time monitoring function, and inaccurate resistance data display; first, resistance adjustment is inconvenient; because many existing swimming resistance equipment, such as traditional resistance trainers, often have fixed resistance or can only be adjusted in a limited way; this results in the trainee being unable to flexibly adjust the resistance according to their own training needs and physical condition, thus affecting the training effect and the satisfaction of personalized needs; second, lack of real-time monitoring function; currently in swimming training, understanding the resistance values ​​of athletes at different speeds is crucial for coaches to formulate training plans and evaluate training effects. However, most of the existing swimming resistance equipment lacks real-time monitoring function and cannot provide real-time feedback on the resistance data of athletes during swimming, which makes it difficult for coaches to accurately grasp the training status of athletes and provide targeted guidance; and the resistance data display is inaccurate; although some swimming resistance equipment claims to have monitoring functions, due to design or technical limitations, their monitoring results are often not accurate enough; this may cause coaches and trainees to misjudge the training effect, thereby affecting the formulation and implementation of training plans;

[0004] In summary, existing swimming resistance equipment has obvious problems in resistance adjustment, real-time monitoring function and resistance data display, which need further improvement and optimization to meet the needs of trainees and improve training effects. Therefore, the above problems need to be solved and optimized. Summary of the invention

Through the setting of the locking assembly, it is convenient to achieve the purpose of quickly connecting the resistance assembly and the waist belt 1 through the connecting seat 5.

[0045] Working principle: In this embodiment, the present invention also proposes a method for using a swimming training resistance device, comprising the following steps:

[0046] Step 1: first, turn on the tension sensor 20 in the present application, then put the waist belt 1 on the user's waist, and adjust the length of the tightening belt 2 hooked on the waist belt 1 to achieve the purpose of tightening the waist belt 1, then through the cooperation of the locking assembly, the connecting seat 5 is clamped in the connecting groove 4, and under the action of the thrust spring 28 and the stabilizing rod 27, the locking block 26 inserted in the locking mouth on the clamping strip is pushed and abutted, so that the connecting seat 5 is stably installed in the connecting groove 4 behind the waist belt 1;

[0047] Step 2, then install one end of the connecting rope 9 on the tail end of the connecting rod 15 by rotating the connecting head 17, and then connect the other end of the connecting rope 9 to the three stabilizing ropes 31 through the threading seat 30, and then choose whether to use the second resistance bucket 35 and the third resistance bucket 36 according to the swimming resistance to be trained. If it is necessary to choose to use the second resistance bucket 35, the resistance of the resistance component after the second resistance bucket 35 is installed is twice that of the first resistance bucket 10 when it is used alone. If it is necessary to choose to use the third resistance bucket 36, the resistance component after the third resistance bucket 36 is installed is The resistance in water is five times that when the first resistance bucket 10 is used alone; and the first resistance bucket 10 is connected and limited with the second resistance bucket 35 and the third resistance bucket 36 by means of magnetic attraction, so as to improve the convenience of disassembling and using the resistance components when in use, and can be used by swimmers with different resistance requirements. At the same time, when the second resistance bucket 35 and the third resistance bucket 36 are used in water, the faster the water flows through the bucket, the tighter the second resistance bucket 35 and the third resistance bucket 36 are connected to the first resistance bucket 10, and the bucket body will not be displaced due to impact;

[0048] Step three, then hang the detection ring 8 with the monitoring component on the anti-detachment hook 7, so as to complete the assembly of the resistance component connected by the connecting rope 9 and the waist belt 1, and turn on the battery module tension sensor 20 for power supply, and make the tension sensor 20 wirelessly connected to the external data receiving terminal, and then screw the anti-detachment nut 16 in the direction away from the detection ring 8, so as to form a moving blank section between the anti-detachment nut 16 and the inner wall of the detection ring 8 for satisfying the lateral movement of the moving bar 13; after that, when the connecting rod 15 is worn by the user to enter the swimming pool for training, the resistance component is located behind the user's forward direction, with the wide mouth facing forward and the narrow mouth facing backward. When water starts to flow through the first resistance bucket 10, the first resistance bucket 10 will straighten the connection rope 9 under the action of water resistance;

[0049] Step 4: After the connecting rope 9 is stretched straight, the connecting rope 9 will pull the connecting rod 15 to move, and the moving connecting rod 15 will pull the moving bar 13 fixed to the mounting seat 14 to move, and the moving moving bar 13 will drive the sliding block 22 to squeeze and move the reset spring 23, and the moving reset spring 23 will drive the thrust ring 24 to apply pressure to the contact end of the tension sensor 20, so that the tension sensor 20 can transmit the pressure to the external data receiving terminal, and the external data terminal can display the resistance of the athlete at different speeds when swimming in the swimming pool, so that the coach can clearly know the speed changes of this athlete in different time periods when swimming, and the resistance values ​​at different speeds;

[0050] Step five, after use, close the tension sensor 20, and screw the anti-detachment nut 16 to move toward the inner wall of the detection ring 8, so that the anti-detachment nut 16 abuts against the inner wall of the detection ring 8, and then the connecting rod 15 pushes the moving bar 13 fixed to the mounting seat 14 to abut against the fixed bar 12, so as to facilitate monitoring of the component when not in use, and avoid the moving bar 13 from falling due to gravity and causing the sliding block 22 to be squeezed, thereby improving the protection effect of the tension sensor 20 when not in use.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
