Abstract
Description
Technical Field
[0001] This utility model relates to the field of body measuring scales, specifically to a full-circumference body measuring scale. Background Technology
[0002] Nowadays, people are paying more and more attention to their health, so they measure their arm circumference, leg circumference, and waist circumference at home to check whether their physique is within a healthy range. Waist circumference is a very important indicator for measuring cardiovascular risk factors. Therefore, in addition to measuring other cardiovascular risk factors such as blood pressure, blood lipids, and blood sugar levels, waist circumference should also be measured. An increased waist circumference increases the risk of coronary heart disease. Therefore, measuring waist circumference is more clinically significant for diagnosing overweight or obesity.
[0003] While existing 3D measuring rulers are already small and convenient, people usually measure arm circumference, leg circumference, and waist circumference together. However, existing 3D measuring rulers do not have the function of marking on the measuring ruler. Therefore, people have to write down each measurement with a pen and paper, which is inconvenient and easy to forget, requiring repeated measurements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a full-circumference measuring scale to address the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a full-circumference measuring ruler, including: a shell, calipers, and a marking device. The marking device is located at the exit of the calipers and includes a marking core, a marking block, a support plate, a push rod, and an auxiliary plate. The support plate is located at the exit of the calipers and is situated on the left side of the calipers. One end face of the support plate is connected to the shell. The support plate has a placement hole. The push rod is movably disposed in the placement hole, and its tip passes through the placement hole and connects to the marking block. The marking core is embedded in the end face of the marking block near the calipers. The auxiliary plate is located at the exit of the calipers and is situated on the left side of the calipers. The right side of the caliper is opposite to the support plate. The aforementioned full-circumference measuring scale moves the marker block and marker core towards the caliper by pushing the push rod, eventually making the marker core contact the end face of the caliper, thus allowing markings to be made on the caliper. Therefore, when people are taking body measurements, they can measure their arm circumference, chest circumference, waist circumference, and thigh circumference, and then compare the marks on the caliper with these body circumference charts. There is no need to record with paper or pen, and even when measuring only the waist circumference, there is no need to worry about misremembering or constantly reciting the measured value. The auxiliary plate can improve the speed and convenience of marking, and can also prevent the marks from being too wide, which would affect the accuracy of the reading.
[0006] Furthermore, the tail end of the push rod passes through the placement hole and extends to the outside of the support plate. An elastic rope is connected to the tail end of the push rod, and the other end of the elastic rope is connected to the outer shell. The elastic rope enables the push rod, the marker block, and the marker core to automatically reset, improving the convenience of marking the device.
[0007] Furthermore, the diameter of the push rod matches the diameter of the placement hole, improving the stability of the push rod during movement.
[0008] Furthermore, the cross-section of the marking core is trapezoidal, and the end of the marking core connected to the marking block is set from wide to narrow from the end closest to the caliper, with the width of the end closest to the caliper ≤ 1mm; by setting the cross-sectional shape and width of the marking core, the marking is avoided from being too wide, thus affecting the accuracy of the reading.
[0009] Furthermore, the marking device also includes a cleaning wipe, a clamp, and a hanging plate. The hanging plate is located at the upper end of the caliper's exit and connected to the outer casing. The cross-section of the hanging plate is a sideways "7" shape. The cleaning wipe is located on the left side of the caliper, and the clamp is located on the right side of the caliper and opposite to the cleaning wipe. The cleaning wipe is connected to the upper end of the clamp and is removably mounted on the hanging plate. The cleaning wipe allows the markings to be erased when the caliper is retracted for the next measurement. The removable design makes it convenient to remove the cleaning wipe when not in use, preventing the markings from being accidentally erased when measuring a larger size first and then a smaller size.
[0010] Furthermore, the end faces of the cleaning wipe and the clamping plate abut against the left and right end faces of the caliper, respectively; the markings are automatically wiped off by the friction generated when the caliper is retracted, and the clamping plate increases the friction, thereby improving the cleaning effect.
[0011] Furthermore, the outer casing is provided with a locking hole located opposite the exit of the caliper, and the end of the caliper is provided with a locking rod that can be placed in the locking hole in a removable manner; the cooperation between the locking rod and the locking hole improves the convenience of measurement.
[0012] Furthermore, the outer wall of the outer shell between the exit of the caliper and the caliper hole has a concave arc-shaped end face, and the circumference between them is 5cm; the arc-shaped end face allows the outer shell to fit snugly against various parts of the human body, facilitating measurement.
[0013] Furthermore, the length between the exit of the caliper and the position of the marking core is 1cm; this facilitates the setting of the caliper scale.
[0014] Furthermore, the caliper has graduations on both ends, with each graduation starting from 6cm. The starting 6cm is the sum of the circumference of the concave arc end face of the outer shell and the length between the marking core and the exit of the caliper. Therefore, the user does not need to calculate; the reading of the graduation at the marked position is the measured size.
[0015] As described above, the full-circumference measuring ruler provided by this utility model has the following beneficial effects: by pushing the push rod, the marking block and marking core are moved towards the caliper, and finally the marking core contacts the end face of the caliper, so that a mark can be made on the caliper. Therefore, when people are taking body measurements, they can measure the arm circumference, chest circumference, waist circumference and leg circumference, and then compare the marks made on the caliper with these body circumference comparison tables (since the arm circumference < leg circumference < waist circumference < chest circumference of normal people, there is no need to worry about confusion when making multiple marks). There is no need to record with paper and pen, and even when only waist circumference is measured, there is no need to worry about misremembering or constantly reciting the measured value. The auxiliary plate can improve the speed and convenience of marking, and can avoid making the marks too wide, which would affect the accuracy of the reading. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figures 1-4As shown, this utility model provides a full-circumference measuring ruler: including a shell 1, a caliper 2, and a marking device 3. The internal connection structure between the caliper 2 and the shell 1, the automatic fixing of the caliper 2 when pulled out, and the automatic retraction of the caliper 2 when a button is pressed are all existing technologies in the field and will not be described further here. The marking device 3 is located at the exit of the caliper 2 and includes a marking core 31, a marking block 32, a support plate 33, a push rod 34, and an auxiliary plate 35. The support plate 33 is located on the caliper... At the outlet of caliper 2, and located to the left of caliper 2, one end face of support plate 33 is connected to outer casing 1. Support plate 33 has placement hole 331. Push rod 34 is movably disposed in placement hole 331. The head end of push rod 34 passes through placement hole 331 and is connected to marking block 32. Marking core 31 is embedded in the end face of marking block 32 near caliper 2. Marking core 31 is made of colored chalk, which is a powder block used to draw lines when cutting clothes. It is similar in nature to chalk and is made by mixing calcined gypsum powder with water. The strip-shaped material solidifies after being inserted into the mold. Sewing chalk, similar to regular chalk, comes in many colors and is used for marking fabric during cutting and sewing. It is easy to remove. The marking auxiliary plate 35 is located at the exit of the caliper 2, on the right side of the caliper 2 opposite to the support plate 33. By pushing the push rod 34, the marking block 32 and the marking core 31 are moved towards the caliper 2, eventually bringing the marking core 31 into contact with the end face of the caliper 2, thus allowing marking to be made on the caliper 2. Therefore, when people are... During the body measurement, after measuring the arm circumference, chest circumference, waist circumference, and leg circumference, you can compare the marks on the caliper 2 with these body circumference comparison charts. Since the normal range of arm circumference < leg circumference < waist circumference < chest circumference, there is no need to worry about confusion when making multiple marks. There is no need to record with paper and pen. Even when measuring only the waist circumference, there is no need to worry about misrecording or constantly reciting the measured value. The auxiliary plate 35 can improve the speed and convenience of marking and can avoid making the marks too wide, which would affect the accuracy of the reading.
[0022] The tail end of the push rod 34 passes through the placement hole 331 and extends to the outside of the support plate 33. The tail end of the push rod 34 is connected to an elastic rope 341. The other end of the elastic rope 341 is connected to the outer shell 1. The push rod 34, the marker block 32 and the marker core 31 can be automatically reset through the elastic rope 341, which improves the convenience of marking when the marking device 3 makes marks.
[0023] The diameter of the push rod 34 matches the diameter of the placement hole 331, which improves the stability of the push rod 34 when it moves.
[0024] The cross-section of the marking core 31 is trapezoidal. The end of the marking core 31 connected to the marking block 32 is set from wide to narrow from the end closest to the caliper 2, and the width of the end closest to the caliper 2 is ≤1mm. By setting the cross-sectional shape and width of the marking core 31, the marking is avoided from being too wide, which would affect the accuracy of the reading.
[0025] The marking device 3 further includes a cleaning wipe 36, a clamping plate 37, and a hanging plate 38. The hanging plate 38 is located at the upper end of the exit of the caliper 2 and is connected to the outer casing 1. The cross-section of the hanging plate 38 is a sideways "7" shape. The cleaning wipe 36 is located on the left side of the caliper 2, and the clamping plate 37 is located on the right side of the caliper 2 and opposite to the cleaning wipe 36. The cleaning wipe 36 is connected to the upper end of the clamping plate 37 and is removably mounted on the hanging plate 38. The cleaning wipe 36 allows the markings to be erased when the caliper 2 is retracted for the next measurement. The removable design makes it convenient to remove the cleaning wipe 36 when not in use, preventing the markings from being accidentally erased when measuring a larger size first and then a smaller size.
[0026] The end faces of the cleaning wipe 36 and the clamp 37 respectively abut against the left and right end faces of the caliper 2. The marks are automatically wiped off by the friction generated when the caliper 2 is retracted. The clamp 37 increases the friction and improves the cleaning effect.
[0027] The outer casing 1 is provided with a locking hole 11, which is located opposite the exit of the caliper 2. The end of the caliper 2 is provided with a locking rod 21, which can be placed in the locking hole 11 in a removable manner. The cooperation between the locking rod 21 and the locking hole 11 improves the convenience of measurement.
[0028] The outer wall of the outer shell 1 between the outlet of the caliper 2 and the caliper hole 11 has a concave arc-shaped end face, and the circumference between them is 5cm. The arc-shaped end face allows the outer shell 1 to fit snugly against various parts of the human body, making it convenient for measurement.
[0029] The length between the exit of the caliper 2 and the position of the marking core 31 is 1cm, which facilitates the setting of the scale 22 of the caliper 2.
[0030] The caliper 2 has scales 22 on both ends. The scales 22 on both ends start from 6cm. The starting 6cm is the circumference of the concave arc end face of the outer shell 1 and the length between the marking core 31 and the exit of the caliper 2. Therefore, the user does not need to calculate, and the reading of the scale 22 marked by the mark is the measured size.
[0031] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
