Description

Technical Field

[0001] The utility model relates to the technical field of pedal tensioners, in particular to a pedal tensioner with replaceable elastic ropes. Background Art

[0002] The Foot Pedal Exerciser is a portable training device for exercising lower limb muscles. It usually consists of a pedal, an adjustment system, and a handle. The Foot Pedal Exerciser can help users perform low-intensity aerobic exercise and lower limb muscle training, and is suitable for people of all ages and health conditions. The use of the Foot Pedal Exerciser is very simple. Users only need to sit on a chair or place the Foot Pedal Exerciser on the ground, put their feet on the pedals and start pedaling. The training effect of the Foot Pedal Exerciser is significant. By pedaling the Foot Pedal Exerciser, users can exercise lower limb muscles such as the front of the thigh (quadriceps femoris), the back of the thigh (biceps femoris), the front of the calf (tibialis muscle) and the back of the calf (gastrocnemius muscle). Continuous pedal training can effectively enhance the strength and endurance of the lower limb muscles, improve the balance of leg strength, and promote blood circulation. In addition, the Foot Pedal Exerciser can also help shape the leg lines, reduce fat accumulation, and make the legs look more symmetrical and toned. By adjusting the resistance of the puller, users can choose the appropriate intensity according to their physical condition and exercise goals. Generally speaking, you can choose a lower resistance when you first start using it, and as you get more accustomed, gradually increase the resistance to make the training more challenging.

[0003] Existing pedal tensioners realize the functions of stretching and resetting by arranging elastic sheets or elastic ropes. However, these elastic sheets or elastic ropes cannot be replaced after being assembled, and cannot meet the needs of different groups of people or the needs of different training stages.

[0084] The handle 20 also has handles 220, which are arranged on both sides of the second connecting portion 210. The handles 220 can also be arranged in a detachable connection mode, so as to facilitate the replacement of different types of handles to meet the needs of different types of people, for example: handles of different thicknesses, handles of different lengths.

[0085] Example 2

[0086] The difference between this embodiment and embodiment 1 is that, in this embodiment, the first mounting member 40 and the second mounting member 50 are respectively a first buckle ring and a second buckle ring;

[0087] The first connecting end 310 and the second connecting end 320 of the elastic cord 30 are buckled on the first buckle ring and the second buckle ring respectively;

[0088] The first accommodating cavity 111 and the second accommodating cavity 211 respectively have a socket for clamping the first buckle ring and the second buckle ring. When the first cover 60 and the first cover 60 are fastened together, the first buckle ring and the second buckle ring are respectively clamped in the first accommodating cavity 111 and the second accommodating cavity 211 through the socket; when the first cover 60 and the first cover 60 are opened, the first buckle ring and the second buckle ring can be taken out from the first accommodating cavity 111 and the second accommodating cavity 211 respectively.

[0089] Example 3

[0090] The difference between this embodiment and embodiment 1 is that, in this embodiment, the first mounting member 40 and the second mounting member 50 are respectively a first buckle hook and a second buckle hook;

[0091] The first connecting end 310 and the second connecting end 320 of the elastic cord 30 are buckled on the first buckle hook and the second buckle hook respectively;

[0092] The first buckle hook and the second buckle hook are respectively fixed on the inner cavity side walls of the first accommodating cavity 111 and the second accommodating cavity 211;

[0093] When the elastic cord 30 is stretched in a direction away from the pedal 10 or the handle 20,

[0094] The pedal 10 uses the first buckle to prevent the first connection end 310 of the elastic cord 30 from being separated from the pedal 10, and the handle 20 uses the second buckle to prevent the second connection end 320 of the elastic cord 30 from being separated from the handle 20;

[0095] When replacing the elastic cord 30, make sure that the elastic cord 30 is not in a stretched state, use a long hook to pass through the first outlet 113 to remove the first connecting end 310 of the elastic cord 30 from the first hook, and pass through the second outlet 213 to remove the second connecting end 320 of the elastic cord 30 from the second hook for replacement.

[0096] Example 4

[0097] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, the elastic rope 30 is an elastic narrow band, and the elastic narrow band includes three pieces, and the three elastic narrow bands are arranged between the pedal 10 and the handle 20 at intervals.

[0098] In actual use, the resistance value of the pedal tensioner can be adjusted by removing a single narrow elastic band.

[0099] In actual use, the width and number of the elastic rope 30 are determined according to the resistance value of the actual elastic band and the resistance value required by the user for training.

[0100] The foot pedal 120 includes a base and a cover plate, which are integrally formed, thus eliminating the need for assembly. Especially for factories that produce in large quantities, even if only one step is optimized, production efficiency can be greatly improved, and production costs can be greatly reduced.

[0101] The foot pedal 120 is integrally formed of a soft rubber material, such as TPR, TPE, silicone, etc. The soft rubber material can improve the comfort when stepping on the foot, commonly known as the "fecal stepping feeling". Therefore, it will not have a hard "discomforting" feeling like a hard pedal.

[0102] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
