Description

Technical Field

[0001] The utility model belongs to the field of fitness equipment design, and is a rowing equipment regulating system capable of regulating load. Background Art

[0002] The water resistance rowing machine, also known as the water resistance rowing machine, is a type of rowing machine. It has a water tank. When the athlete exercises, it can simulate the real rowing method, allowing the athlete to truly feel that he is rowing. It has a more obvious effect on strengthening the muscles of the legs, waist, upper limbs, chest, and back.

[0003] The resistance of existing water resistance rowing machines is determined by the rated resistance of the water resistance box, and athletes cannot adjust the load by themselves. Utility Model Content

[0004] The purpose of the utility model is to provide a rowing machine regulating system capable of adjusting load.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a transmission system for adjusting the load of a rowing machine, including a support frame, a seat slidably connected to the support frame, footrests are connected on both sides of the seat, and the seat performs reciprocating sliding motion along the length direction of the support frame; the support frame is also fixedly connected to a water resistance box and a transmission part that transmits motion to the athlete through the water resistance box, the transmission part is provided with a resilient handheld structure for the athlete to hold, a load-adjustable structure is provided inside the transmission part, a transmission shaft with paddles is provided in the water resistance box, the load-adjustable structure is connected to the transmission shaft by a belt, and the resilient handheld structure is connected to the load-adjustable structure, and the size of the load of the load-adjustable structure is controlled.

[0006] According to the utility model, further, the load-adjustable structure includes a volute spring for increasing the load, a connecting shaft is coaxially installed at the center of the volute spring, the connecting shaft is connected to the transmission shaft through a belt, and the resilient handheld structure is connected to the connecting shaft.

[0007] According to the utility model, further, the resilient handheld structure has an elastic band, and the elastic band is connected to the connecting shaft.

[0008] The beneficial effects of the utility model are as follows: by connecting the load-adjustable structure with the resilient hand-held structure, the spiral spring generates a greater torsion force under the external force of the athlete, that is, the load is increased. The load is further adjusted according to the tension applied by the athlete to the elastic band, thereby improving the applicability of the rowing machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the utility model;

[0010] Among them, 100-support frame, 200-seat, 300-water resistance box, 310-transmission shaft, 400-transmission part, 410-volute spring, 420-connecting shaft, 430-belt, 500-handheld structure, 510-elastic belt, 600-foot pedal. DETAILED DESCRIPTION

[0011] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0012] The utility model provides a rowing machine adjustment system capable of adjusting load, such as Figure 1 As shown, the support frame 100 includes a support frame 100, which is in the shape of a long strip. A seat 200 is slidably connected to the support frame 100. Footrests 600 are connected to both sides of the seat 200. The footrests 600 do not contact the ground, and the seat 200 performs reciprocating sliding motion along the length direction of the support frame 100. A water resistance box 300 and a transmission part 400 that transmits motion to the athlete through the water resistance box 300 are also fixedly connected to the support frame 100. A resilient handheld structure 500 for the athlete to hold is provided on the transmission part 400. A transmission shaft 310 with paddles is provided in the water resistance box 300, and one end of the transmission shaft 310 is connected to the transmission part 400. The water resistance box 300 is filled with liquid. The athlete sits on the seat 200 with both feet on the footrests 600 on the corresponding sides, holds the handheld structure 500 with his hands, and leans back. The athlete's buttocks drive the seat 200 to slide toward the water resistance box 300. The handheld structure 500 relies on the resilience of its own elastic structure to pull the athlete's upper body toward the water resistance box 300. The buttocks drive the seat 200 to move away from the water resistance box 300 along the length direction of the support frame 100, thereby achieving a reciprocating training.

[0013] Specifically, the handheld structure 500 has an elastic band 510 , one end of which is connected to the transmission part 400 , and the other end is used for the athlete to pull, and the purpose of exercise is achieved by pulling the elastic band 510 .

[0014] In order to increase the load, a load-adjustable structure is provided in the transmission part 400, and the load-adjustable structure includes a spiral spring 410 for increasing the load, and a connecting shaft 420 is coaxially installed at the center of the spiral spring 410. The shaft head of the connecting shaft 420 is connected to the transmission shaft 310 through a belt 430, and the elastic belt 510 is connected to the connecting shaft 420. When an external force is applied to the connecting shaft 420, the connecting shaft 420 will transfer the received force to the spiral spring 410, so that the spiral spring 410 generates a greater torsion force, that is, the load is increased. The load is further adjusted according to the tension applied by the athlete to the elastic belt 510, thereby improving the applicability of the rowing machine.

[0015] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
