Technical Field

[0001] The utility model relates to the field of body fat scales, in particular to a telescopic structure, a handle and a body fat scale. Background Art

[0002] A body fat scale is a tool used to measure body fat and other parameters of the human body. In order to ensure that the calculated body fat and other parameters are more accurate, the body fat scale usually has eight electrodes, including four electrodes distributed on the handle and four electrodes distributed on the scale body, which measure the impedance of the upper and lower limbs of the human body respectively.

[0003] However, in the existing eight-electrode body fat scales, the handle length cannot be adjusted.

[0030] Reference Figures 1 to 4 , a telescopic structure, comprising a jacket 10, a telescopic rod 20, a guide rail 30, a limiter 40 and a reset member 50;

[0031] The telescopic rod 20 is movably disposed in the outer jacket 10;

[0032] The guide rail 30 is disposed between the outer sleeve 10 and the telescopic rod 20 and connected to the inner wall of the outer sleeve 10. The guide rail 30 is provided with a receiving groove 31 and a limiting groove 32 which are interconnected.

[0033] The limiter 40 is rotatably connected to the telescopic rod 20 and extends into the receiving groove 31 or the limiter groove 32;

[0034] The reset member 50 is disposed on the telescopic rod 20 and abuts against the outer sleeve 10;

[0035] The limit system 40 can enter the receiving groove 31 and be confined in the limit groove 32 under the drive of the telescopic rod 20, so that the telescopic rod 20 is extended relative to the outer sleeve 10; or enter the receiving groove 32 and be confined in the receiving groove 31 under the drive of the telescopic rod 20, so that the telescopic rod 20 is shortened relative to the outer sleeve 10.

[0036] In the present invention, the application of the telescopic structure in an eight-electrode body fat scale is taken as an example for explanation. Specifically, the eight-electrode body fat scale includes a handle, a scale body 80, four first electrode sheets 91 arranged on the handle, and four second electrode sheets 92 arranged on the scale body 80, wherein the four second electrode sheets 92 on the scale body 80 are connected to the control board in the scale body 80, and the four first electrode sheets 91 on the handle are connected to the control board in the scale body 80 through connecting lines; when children and other users use the body fat scale, the handle in a shortened state can be used to measure the upper limb impedance, and when adults and other users use the body fat scale, the handle in an extended state can be used to measure the upper limb impedance; the four second electrode sheets 92 on the scale body 80 can measure the lower limb impedance, and the control board calculates the body fat parameters and the like based on the feedback data.

[0037] Taking the adjustment of the handle from the shortened state to the extended state as an example for explanation, the limit system 40 has a long side and a short side. Specifically, when the handle is in the shortened state, the limit system 40 is received in the receiving groove 31 with the long side parallel to the extension direction of the telescopic rod 20. During adjustment, the first outer sleeve 10 is kept stationary, and the second outer sleeve 10 on the opposite side of the first outer sleeve 10 and the telescopic rod 20 are pulled to move in the opposite direction (the reset member 50 is in a compressed state), thereby driving the limit system 40 with the receiving groove 31 to enter into the limit groove 32 until it contacts the abutment portion 70 provided in the limit groove 32, so that the limit system 40 rotates in the limit groove 32 (rotates until the long side is parallel to the extension direction of the telescopic rod 20). When the second outer cover 10 is released, the second outer cover 10 and the telescopic rod 20 move in the opposite direction under the action of the reset member 50, driving the limit system 40 to abut against the limit boss 60 located between the receiving groove 31 and the limit groove 32, so as to be limited in the limit groove 32; since the limit system 40 moves a distance (the length of the receiving groove 31) in the telescopic direction relative to the initial position, that is, the first outer cover 10 is extended a distance relative to the second outer cover 10, which can meet the use needs of users such as adults; the utility model has the advantage that: through the above structure, the length of the handle can be quickly adjusted to meet the use needs of different groups of people, and has very good practicality.

[0038] In one embodiment, an avoidance groove 33 connected to the limit groove 32 is provided on the guide rail 30, and the receiving groove 31, the limit groove 32 and the avoidance groove 33 are arranged along the extension direction of the telescopic rod 20. The avoidance groove 33 is used to provide an avoidance space for the limit system 40 when the telescopic rod 20 is shortened relative to the outer sleeve 10.

[0039] In one embodiment, a limiting boss 60 is disposed between the receiving groove 31 and the limiting groove 32 , and the limiting mechanism 40 can abut against the limiting boss 60 so that the limiting mechanism 40 is limited in the limiting groove 32 .

[0040] In one embodiment, an abutment portion 70 is disposed in the limiting groove 32 , and the limiting device 40 can contact the abutment portion 70 , so that the limiting device 40 can rotate in the limiting groove 32 and be confined in the limiting groove 32 .

[0041] As a first embodiment of the connection between the guide rail 30 and the outer casing 10, the guide rail 30 is connected to the inner wall of the outer casing 10 via a detachable structure.

[0042] In one embodiment, the detachable structure is configured as a bolt connection structure or a clamping structure.

[0043] As a second embodiment of the connection between the guide rail 30 and the outer sleeve 10 , the guide rail 30 is bonded to the inner wall of the outer sleeve 10 .

[0044] As a second embodiment of the connection between the guide rail 30 and the outer sleeve 10 , the guide rail 30 and the outer sleeve 10 are integrally formed.

[0045] A handle comprises the telescopic structure.

[0046] A body fat scale comprises the handle.

[0047] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
