DETAILED DESCRIPTION

[0021] The utility model is further explained in connection with the drawings and specific embodiments.

[0022] As Figures 1 to 3 shown, the fitness resistance band includes resistance band body 1, and further includes tension measurement structure 2, and the tension measurement structure 2 includes stretchable flexible sensor 22, first clamping device 21, second clamping device 24 and force measurement structure host 25, and the stretchable flexible sensor 22 includes sensor body 221 and lead wire 222 connected with the sensor body 221, and the first clamping device 21 and the second clamping device 24 are connected with both ends of the sensor body 221 respectively, and the force measurement structure host 25 is connected with the second clamping device 24 and is electrically connected with the lead wire 222, and the force measurement structure host 25 can display the force measured by the stretchable flexible sensor 22, and the first clamping device 21 and the second clamping device 24 clamp the resistance band body 1 respectively, and the resistance band body 1 and the sensor body 221 between the first clamping device 21 and the second clamping device 24 are straightened.

[0023] When the fitness resistance band is used to stretch, the stretchable flexible sensor 22 stretches along with the resistance band body 1, and the stretchable flexible sensor 22 generates a measurement signal, which is transmitted to the force measurement structure host 25 for display, so that the tension measurement and display of the fitness resistance band are realized.

[0024] The tension measurement and display mode of the utility model is suitable for various use modes of the fitness resistance band, and the application range is wide, and the tension measurement structure 2 can also be detached from the resistance band body 1 when the tension is not needed to be measured. The tension measurement and display of the fitness resistance band are beneficial to the exerciser and trainer to know the accurate situation of exercise, and accordingly control the exercise process and designated exercise plan.

[0025] The resistance band body 1 is the same as existing fitness resistance bands, being a strip or ring-shaped band, and the material can be rubber. The stretchable flexible sensor 22 is a prior art product, disclosed in patent applications with application numbers 202110899693.2, 201910721294.X, and 201810150112.3. Clearly, the tensile force signal generated by the stretchable flexible sensor 22 of this utility model should be compatible with the tensile force generated by the stretching of the resistance band body 1.

[0026] The first clamp 21 and the second clamp 24 should be able to securely clamp onto the resistance band body 1, and their specific structure can be as follows: Figure 4 As shown, the first clamp 21 includes a first clamping plate 211, a second clamping plate 212, and two first fasteners 213; the two first fasteners 213 are respectively close to the two ends of the first clamping plate 211, one first fastener 213 passes through the first clamping plate 211 and is threaded to one end of the second clamping plate 212, and the other first fastener 213 passes through the first clamping plate 211 and is threaded to the other end of the second clamping plate 212.

[0027] The resistance band body 1 passes between the first clamping plate 211 and the second clamping plate 212, and between two first fasteners 213. Tightening the first fasteners 213 will clamp the resistance band body 1 between the first clamping plate 211 and the second clamping plate 212.

[0028] The second clamp 24 can also adopt the same structure, i.e., as Figure 5 As shown, the second clamp 24 includes a third clamping plate 241, a fourth clamping plate 242, and two second fasteners 243; the two second fasteners 243 are respectively close to both ends of the third clamping plate 241, one second fastener 243 passes through the third clamping plate 241 and is threaded to one end of the fourth clamping plate 242, and the other second fastener 243 passes through the third clamping plate 241 and is threaded to the other end of the fourth clamping plate 242.

[0029] The first clamp 21 and the second clamp 24 are firmly clamped onto the resistance band body 1, enabling the stretchable flexible sensor 22 to extend and retract synchronously with the resistance band body 1.

[0030] The force measuring structure host 25 can be designed based on existing force gauges, and its functions include powering the stretchable flexible sensor 22 and displaying the signals from the stretchable flexible sensor 22. Specifically, as follows... Figure 6As shown, the force measuring structure main unit 25 includes a housing 251, a battery 252, and a display screen 253. The housing 251 is connected to a second clamp 24, which has a through hole 245. A connecting wire 222 passes through the through hole 245 and extends into the housing 251. The battery 252 is fixed inside the housing 251, and the display screen 253 is mounted on the housing 251. The battery 252 powers the stretchable flexible sensor 22 and the display screen 253. The signal from the stretchable flexible sensor 22 is transmitted to the display screen 253, which displays the force measured by the stretchable flexible sensor 22. Both the display screen 253 and the battery 252 can be existing technology products.

[0031] Furthermore, the preferred fitness resistance band of this utility model includes a thin film sleeve 23, which is sleeved on the outside of the sensor body 221. The two ends of the thin film sleeve 23 are respectively connected to the first clamp 21 and the second clamp 24. When the sensor body 221 is straightened, the thin film sleeve 23 is in a compressed state.

[0032] The function of the membrane sleeve 23 is to protect the stretchable flexible sensor 22 from direct contact. It also limits the maximum elongation of the stretchable flexible sensor 22; sturdy membrane sleeve 23 prevents further stretching of the stretchable flexible sensor 22, thus protecting it. When the sensor body 221 is sturdy (straightened but not stretched), the membrane sleeve 23 is in a compressed state and can stretch. Therefore, when the membrane sleeve 23 is not sturdy, it does not create resistance to the elongation of the resistance band body 1 and the stretchable flexible sensor 22.

[0033] Furthermore, the preferred embodiment of this utility model includes a positioning rod 26; each end of the first clamp 21 has a first insertion hole 214 arranged along the length direction of the first clamp 21, and each end of the second clamp 24 has a second insertion hole 244 arranged along the length direction of the second clamp 24; the positioning rod 26 is U-shaped, and when the resistance band body 1 is straightened, both ends of the positioning rod 26 can be inserted into the first insertion hole 214 and the second insertion hole 244 respectively, and the positioning rod 26 can be pulled out. Preferably, the cross-sectional shape of the insertion hole 214, the second insertion hole 244, and the positioning rod 26 are all square.

[0034] The function of the positioning rod 26 is as follows: When the tension measuring structure 2 is not in use, the positioning rod 26 can be installed to restrict the relative movement of the first clamp 21 and the second clamp 24, thereby preventing the stretchable flexible sensor 22 from deforming when the tension measuring structure 2 is not in use, and further protecting the stretchable flexible sensor 22. When the tension measuring structure 2 is installed on the resistance band body 1, the positioning rod 26 should be removed. The positioning rod 26 can be made of plastic with slight elasticity, and has a small interference fit with the first insertion hole 214 and the second insertion hole 244. Thus, inserting and removing the positioning rod 26 requires a certain amount of force to prevent it from easily moving out of the first insertion hole 214 and the second insertion hole 244.
