[0049] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0050] The following is combined with Figures 1 to 10 The meter 100 according to the embodiment of the present invention will be described in detail.

[0051] like Figure 1 and Figure 2 As shown, the meter 100 according to the embodiment of the present invention includes a dial 10 , a measurement indicating device 20 , an upper limit indicating device 30 and a lower limit indicating device 40 .

[0052] Specifically, a scale 11 is provided on the dial 10, and a measurement indicating device 20 is provided on the dial 10. One end of the measurement indicating device 20 can move within the scale 11 on the dial 10 to indicate the measurement value. An upper limit indicating device 30 and a lower limit indicating device 40 are respectively provided on the dial 10 and move synchronously with the measurement indicating device 20. One end of the upper limit indicating device 30 and one end of the lower limit indicating device 40 are respectively located on both sides of one end of the measurement indicating device 20 and indicate different measurement values ​​respectively. The measurement value corresponding to the upper limit indicating device 30 and the measurement value corresponding to the lower limit indicating device 40 cooperate to define the interval value measured by the measurement indicating device 20.

[0053] In other words, the instrument 100 according to the embodiment of the present invention is mainly composed of a dial 10, a measurement indicating device 20, an upper limit indicating device 30 and a lower limit indicating device 40, wherein the dial 10 is provided with a scale 11 for displaying the measurement value, the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 are all arranged on the dial 10, and one end of the measurement indicating device 20 can be movable on the dial 10 to indicate different measurement values ​​within the range of the scale 11.

[0054] One end of the upper limit indicating device 30 and one end of the lower limit indicating device 40 are respectively arranged on both sides of the measurement indicating device 20, and the upper limit indicating device 30 and the lower limit indicating device 40 rotate together with the measurement indicating device 20. The upper limit indicating device 30 is located on one side of the measurement indicating device 20, and can be used to indicate the upper limit value of the measurement value. The lower limit indicating device 40 is located on the other side of the measurement indicating device 20, and can be used to indicate the lower limit value of the measurement value. The range composed of the upper limit value and the lower limit value constitutes the interval range of the measurement value. When reading the value, the user can not only directly read the measurement value, but also directly read the interval value of the measurement value, which intuitively gives the interval range of the true value of the measured parameter. The structure is simple, and it is more convenient to use. It effectively guarantees high-precision readings and provides users with more effective, true and accurate information.

[0055] Therefore, according to the instrument 100 of the embodiment of the present invention, by arranging the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 on the dial 10, when in use, the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 can respectively indicate different scales, the measurement indicating device 20 can be used to indicate the measurement value, the upper limit indicating device 30 and the lower limit indicating device 40 can cooperate to limit the interval value of the measurement value indicated by the measurement indicating device 20, when the user reads the number, he can not only directly read the measurement value, but also directly read the interval value of the measurement value, which is more convenient to use.

[0056] Specifically, the measurement indicating device, the upper limit indicating device and the lower limit indicating device are pointers respectively, the measurement indicating device is the middle pointer, the upper limit indicating device and the lower limit indicating device are the remaining pointers on both sides of the middle pointer respectively, the middle pointer indicates the measured value, and the remaining pointers are used to indicate the interval boundary values ​​of the true value under different probabilities, the measurement accuracy is high, and it is very convenient to use.

[0057] According to one embodiment of the present invention, the meter 100 further includes: a rotating shaft 50, which is disposed on the dial 10, and the other end of the measurement indicating device 20 is connected to the rotating shaft 50, and the measurement indicating device 20 can rotate around the rotating shaft 50 to indicate different measurement values.

[0058] Specifically, Figures 2 to 8 As shown, in the present application, the rotating shaft 50 can also be one of the components of the instrument 100. The rotating shaft 50 is set at the center position of the dial 10 and is connected to the other end of the measurement indicating device 20. The measurement indicating device 20 can rotate 360 ​​degrees around the rotating shaft 50 on the dial 10. One end of the measurement indicating device 20 indicates different measurement values ​​on the scale 11 displaying the measurement value. The rotating shaft 50 can fix the measurement indicating device 20 on the dial 10, so that the measurement indicating device 20 rotates around the rotating shaft 50 on the dial 10, thereby achieving the purpose of measuring the required measurement parameters.

[0059] It should also be noted that the instrument 100 may not include the rotating shaft 50. Figure 1 As shown, the instrument dial 10 is generally formed as a long strip-shaped scale structure. The dial 10 is provided with a scale 11 extending along its length direction for displaying measurement values. The measurement indicating device 20 is provided on the dial 10 and is movable along the length direction of the dial 10 .

[0060] When the mechanical type 100 of this structure is not measuring, the measuring indicator device 20 indicates the original scale value of the scale. When measuring a certain parameter, the measuring pointer 20 moves accordingly to indicate the corresponding scale value. An upper limit value indicating device 30 and a lower limit value indicating device 40 are provided on both sides of the measuring indicator device 20, which are fixedly connected to the measuring indicator device 20 and move synchronously with the measuring indicator device 20. The range composed of the indicated upper limit value and lower limit value constitutes the interval range of the measured value, which intuitively gives accurate and effective readings and provides convenience for users.

[0061] In some specific embodiments of the present invention, Figure 2 and Figure 5 As shown, the other end of the upper limit indicating device 30 and the other end of the lower limit indicating device 40 are respectively connected to the rotating shaft 50 and can rotate around the rotating shaft 50.

[0062] That is to say, the upper limit indicating device 30 and the lower limit indicating device 40 are respectively located on both sides of the measuring indicating device 20, and like the measuring indicating device 20, the other ends of the upper limit indicating device 30 and the lower limit indicating device 40 are respectively fixedly connected to the rotating shaft 50, and can rotate on the dial 10 around the rotating shaft 50, and rotate synchronously with the measuring indicating device 20, so as to intuitively identify the interval range of the measured value and provide accurate and effective information on the measured parameters.

[0063] In some other specific embodiments of the present invention, the other end of the upper limit indicating device 30 and the other end of the lower limit indicating device 40 are respectively connected to the measurement indicating device 20 .

[0064] Specifically, Figure 6 As shown, in the present application, the other end of the upper limit indicating device 30 and the other end of the lower limit indicating device 40 are respectively connected to the measuring indicating device 20, and the upper limit indicating device 30 is arranged on one side of the measuring indicating device 20, and the lower limit indicating device 40 is arranged on the other side of the measuring indicating device 20. The upper limit indicating device 30 and the lower limit indicating device 40 form a whole with the measuring indicating device 20, and rotate synchronously on the dial 10. The upper limit indicating device 30 and the lower limit indicating device 40 indicate different interval ranges of different measurement values, providing accurate and effective readings for users.

[0065] Preferably, a connecting rod 60 perpendicular to the measuring indicating device 20 is provided on the measuring indicating device 20 , and the upper limit indicating device 30 and the lower limit indicating device 40 are respectively located on both sides of the measuring indicating device 20 and are respectively connected to both ends of the connecting rod 60 .

[0066] Reference Figure 6As shown, the connecting rod 60 is fixedly connected to the measuring indicating device 20 and is vertically arranged with respect to the measuring indicating device 20. The two ends of the connecting rod 60 are distributed on both sides of the measuring indicating device 20, and are respectively connected with the other ends of the upper limit indicating device 30 and the lower limit indicating device 40. In this way, the upper limit indicating device 30 and the lower limit indicating device 40 are respectively distributed on both sides of the measuring indicating device 20, and can respectively indicate the upper limit value and the lower limit value of the measured value, thereby constituting the interval range of the measured value, and ensuring that the read value is more accurate.

[0067] Further, according to an embodiment of the present invention, the connecting rod 60 is disposed between one end and the midpoint of the measurement indicating device 20 and is disposed adjacent to the midpoint.

[0068] like Figure 6 As shown, in the present application, the other end of the measuring indicating device 20 is connected to the rotating shaft 50 on the dial 10 to realize the rotation of the measuring indicating device 20 on the dial 10, and one end indicates different measurement values ​​according to different rotation positions, and the connecting rod 60 is arranged at a position adjacent to the midpoint of the measuring indicating device 20.

[0069] Specifically, the connecting rod 60 is arranged between the midpoint of the measuring indicating device 20 and one end indicating the measured value, and is relatively close to the midpoint of the measuring indicating device 20, so that the length of the upper limit indicating device 30 and the lower limit indicating device 40 connected by the connecting rod 60 is shortened, and is only the distance from the connecting rod 60 to the indicating scale 11, making the structure of the instrument simpler and saving the cost of producing the instrument. In addition, the angle formed by the spacing between the upper limit indicating device 30 and the lower limit indicating device 40 and the measuring indicating device 20 is smaller, so that the accuracy of the measured interval value is higher.

[0070] Advantageously, the upper limit indicating device 30 , the lower limit indicating device 40 , the connecting rod 60 and the measurement indicating device 20 are integrally formed.

[0071] In other words, the connecting rod 60 is fixedly connected to the measuring indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 are respectively connected to the two ends of the connecting rod 60, and the upper limit indicating device 30, the lower limit indicating device 40, the connecting rod 60 and the measuring indicating device 20 together form a whole. The upper limit indicating device 30, the lower limit indicating device 40, the connecting rod 60 and the measuring indicating device 20 are integrally formed, not only the pointer structure is light and the entire instrument structure is simple, but also the overall structure of the pointer indicating the reading is stable, the upper limit indicating device 30 and the lower limit indicating device 40 can stably display the interval range of the measured value, and the reading given is accurate and effective. In addition, the material cost of producing the instrument is saved, and the production cost is saved.

[0072] According to one embodiment of the present invention, the distance between one end of the upper limit indicating device 30 and one end of the measurement indicating device 20 is equal to the distance between one end of the lower limit indicating device 40 and one end of the measurement indicating device 20 .

[0073] It can be understood that the upper limit indicating device 30 and the lower limit indicating device 40 are respectively distributed on both sides of the measuring indicating device 20. Since the other ends of the upper limit indicating device 30 and the lower limit indicating device 40 are respectively connected to the connecting rod 60 on the measuring indicating device 20, the measuring indicating device 20 is separated from the upper limit indicating device 30 and the lower limit indicating device 40 by a distance, and the spacing distance between the measuring indicating device 20 and the upper limit indicating device 30 is equal to the spacing distance between the measuring indicating device 20 and the lower limit indicating device 40. In this way, the upper limit value interval range indicated by the upper limit indicating device 30 is the same as the lower limit value interval range indicated by the lower limit indicating device 40. That is to say, the absolute values ​​of the upper limit value indicated by the upper limit indicating device 30 and the lower limit value indicated by the lower limit indicating device 40 are equal. In this way, the read measurement value is in the middle position of the measurement interval. The upper limit interval and the lower limit interval of the same range ensure the accuracy of the read measurement value and provide reliable measurement information for the user.

[0074] Preferably, in some specific embodiments of the present invention, the distance between one end of the upper limit value indicating device 30 and one end of the measurement indicating device 20 is adjustable, and the distance between one end of the lower limit value indicating device 40 and one end of the measurement indicating device 20 is adjustable.

[0075] Specifically, on one side of the measuring indicating device 20, there is a certain distance between one end of the upper limit indicating device 30 and one end of the measuring indicating device 20, and the distance of this interval can be adjusted. Similarly, the distance between one end of the lower limit indicating device 40 and one end of the measuring indicating device 20 can also be adjusted, and in each adjustment process, the adjustment amplitude of the two interval distances can be the same to meet the needs of actual measurement parameters. For example, the measurement value interval required to be measured by the original instrument is 3%, but with the change of the use environment, it is determined through analysis that the parameter measured by the instrument needs to be measured at a measurement interval of 4%. A smaller adjustment or replacement can be made to make it suitable for the new accuracy or measurement value interval range to meet the actual measurement needs.

[0076] According to one embodiment of the present invention, the measuring indicating device is a wide-width pointer, on which a probability scale 113 and a deviation value scale 114 are provided, and the upper limit indicating device and the lower limit indicating device are pointers respectively, and the upper limit indicating device and the lower limit indicating device are respectively movably arranged on the measuring indicating device to correspond to different probability scales 113 and deviation value scales 114.

[0077] That is, the measurement value indicating device adopts a wide pointer, as follows Figure 2 and Figure 3 As shown, a probability scale 113 and a deviation value scale 114 are arranged on the wide pointer, the side close to the free end of the pointer is the probability scale 113, and the side away from the free end of the pointer is the deviation value scale 114, the wide pointer can indicate the interval range and mark the probability size, the upper limit value indicating device and the lower limit value indicating device are pointers respectively, the upper limit value indicating device and the lower limit value indicating device are respectively arranged on both sides of the measurement indicating device and can be rotatable relative to the measurement indicating device, wherein the middle pointer indicates the measurement value, and the remaining pointers are used to indicate the interval boundary values ​​of the true value under different probabilities, and the remaining pointers can be rotated according to different probabilities that need to be measured, rotated to the specified position and locked, the probability scale 113 and the deviation value scale 114 marked on the wide pointer, the rotatable pointer can be conveniently adjusted to the required probability value through the probability scale 113, and the deviation size of the indicated value and the measured value can be intuitively observed through the deviation value scale 114, the operation is convenient, and the measurement accuracy is high.

[0078] Preferably, the probability scale 113 and the deviation value scale 114 have different colors, such as the probability scale 113 is marked in red and the deviation value scale 114 is marked in green. In this way, the measurement personnel can easily distinguish the probability scale 113 and the deviation value scale 114, which is not easy to make mistakes. It is easy to read the probability size and the deviation value size of the measured value, avoiding reading errors caused by confusing the probability scale 113 and the deviation value scale 114, which provides great convenience for the measurement personnel to read the readings.

[0079] Reference Figure 2 and Figure 3 It can be seen that further, there are two upper limit value indicating devices and two lower limit value indicating devices. There are two upper limit value indicating devices on one side of the measurement value indicating device, which can respectively indicate different probability sizes and different deviation ranges on one side of the measurement value indicating device, and there are two lower limit value indicating devices on the other side of the measurement value indicating device, which can respectively indicate different probability sizes and different deviation ranges on the other side of the measurement value indicating device.

[0080] It is understandable that if Figure 2 and Figure 3 As shown, the two upper limit value indicating devices on one side of the measurement value indicating device and the two lower limit value indicating devices on the other side of the measurement value indicating device can be rotated and adjusted to correspond to each other on both sides of the measurement value indicating device, or can be rotated and adjusted to not correspond according to actual measurement needs.

[0081] It should also be noted that, depending on the actual measurement situation, the range of the true value under different probabilities may change, and the entire indicating device can be disassembled or replaced to meet the actual measurement needs. For example, in some measurement situations, only a few fixed probability values, such as 95%, 90%, and 85%, are required. Figure 3 The indicating device shown can be simplified to Figure 4 If the probability value to be measured does not need to be intuitively identified or is already well known to the measurement personnel, Figure 4 The device shown can be simplified to Figure 7 If the device shown needs to measure fewer probability values, Figure 7 The indicating device shown can be simplified to Figure 8 The indicating device shown, wherein the pointers of the upper limit indicating device and the lower limit indicating device can be rotated and adjusted and locked and fixed, so that the indicating device can be disassembled and replaced with a different indicating device according to different actual measurement requirements, the structure is simpler, making the measurement process more convenient and easier to read.

[0082] It should be further explained that the instrument has various measurement implementation forms, and can also emit infrared rays to indicate the interval range of the true value, and use the distribution range of infrared rays to identify a certain probability interval range of the true value.

[0083] In some specific embodiments of the present invention, the dial 10 is formed in a circular shape, and the scale 11 includes a plurality of scale lines, and the plurality of scale lines are arranged in a circle at intervals along the circumference of the dial 10 .

[0084] Reference Figure 2 , Figure 5 and Figure 6 As shown, the dial 10 is circular in shape, and has a scale 11 around the circumference of the dial 10 near the periphery. The scale 11 is composed of a plurality of scale lines, and the plurality of scale lines are evenly spaced at circumferential positions of the dial 10, wherein the two intervals formed by any one scale line and the other two adjacent scale lines are equal, and the plurality of scale lines together constitute a circle, and different scale lines represent different values. When the measurement indicating device 20 indicates a certain scale line, it represents that the measured parameter is the scale value, and accordingly, a certain scale line indicated by the upper limit indicating device 30 and the lower limit indicating device 40 represents the upper limit value and the lower limit value of the measured value.

[0085] In some other specific embodiments of the present invention, the dial 10 is formed in a non-circular shape, and the scale 11 includes a plurality of scale lines, and the plurality of scale lines are arranged in a zigzag or spiral shape at intervals along the circumference of the dial 10 .

[0086] Specifically, refer to Fig. 9As shown, in the present application, the dial 10 of the instrument can adopt a non-circular dial 10 in addition to the common circular dial 10, for example Figure 4 Correspondingly, the scale lines on the non-circular dial 10 are also non-circular scale lines, and the non-circular scale lines can be arranged as scale lines composed of broken lines or spiral lines, so that the length of the scale lines in the same area (for example, the same angle interval of the circular dial 10) will be greatly increased. Due to the increase in the length of the scale lines, there will be more space on the scale lines to arrange more subdivided scales 112, thereby improving the accuracy of the scale 11, further improving the accuracy of the read measurement value, providing users with accurate and effective information, and meeting the actual needs of high-precision measurement.

[0087] According to one embodiment of the present invention, the measurement indicating device 20 includes two measurement indicating devices 20 , which are arranged on the dial 10 at intervals along the axial direction of the dial 10 , and the two measurement indicating devices 20 move synchronously and their orthographic projections on the dial 10 coincide.

[0088] like Fig.10 As shown, two measuring indicating devices 20 are provided on the dial 10, one end of the two measuring indicating devices 20 indicates the scale value, and the other end is fixedly connected to the rotating shaft 50, and the two measuring indicating devices 20 are spaced apart along the axial direction of the rotating shaft 50, and the two measuring indicating devices 20 rotate synchronously with the rotation of the rotating shaft 50.

[0089] It should be understood that there is usually a certain gap between the pointer of the instrument 100 and the dial 10 to ensure that the pointer can operate normally. When the user reads the pointer on the dial 10, if the user's line of sight is not facing the pointer or the dial, it will cause a certain deviation in the reading.

[0090] However, according to the mechanical dial 100 of the embodiment of the present invention, when two pointers are arranged axially and spaced apart from each other along the dial 10, when the user reads the pointers, if the lower pointer is blocked by the upper pointer, the orthographic projections of the two measuring indicating devices 20 overlap, and the user only sees one measuring indicating device 20, which means that the user's line of sight is facing the dial 10, and the reading is accurate at this time; if the lower pointer cannot be blocked by the upper pointer, the orthographic projections of the two measuring indicating devices 20 do not overlap, and the user can see that there are two measuring indicating devices 20, which means that the user's line of sight is not facing the dial, and the reading error is relatively large at this time, so as to identify and remind the user whether the reading method is correct, thereby ensuring the accuracy of the read value.

[0091] Preferably, in some specific embodiments of the present invention, the two measurement indicating devices 20 have different colors.

[0092] Specifically, in the present application, the colors of the upper and lower measurement indicating devices 20 spaced apart along the axial direction of the dial 10 are different, and two colors that are easy to distinguish are preferably selected, such as the upper measurement indicating device 20 can be black, and the lower measurement indicating device 20 can be red. When the user does not read the value correctly, the lower red measurement indicating device 20 will be observed. When and only when the user reads the value correctly, the lower red pointer will be blocked, and only the upper black pointer will be visible. Therefore, by setting the two measurement indicating devices 20 with different color markings, it is easier for the user to find problems when reading and correct reading errors in a timely manner, which can assist and ensure that the user reads the dial 10 correctly, avoid inaccurate measurement values ​​due to incorrect reading posture of the user, and further ensure the reliability of the information provided from the observer's perspective.

[0093] In some other specific embodiments of the present invention, one side surface of the dial 10 where the scale 11 is provided is formed as a reflective surface.

[0094] In other words, only one measuring indicating device 20 may be provided on the dial 10, and the side of the dial 10 with the scale 11 may be set as a reflective surface, such as a reflective mirror or a mirror-like surface, so that the measuring indicating device 20 will have a parallel mirror image in the reflective surface of the dial 10. When the user reads the value vertically, the measuring indicating device 20 on the dial 10 and the mirror image formed by the measuring indicating device 20 in the dial 10 overlap, and only one measuring indicating device 20 is seen. When the user reads the value not vertically, the measuring indicating device 20 on the dial 10 and the mirror image formed by the measuring indicating device 20 in the dial 10 do not overlap, and two measuring indicating devices 20 are seen. By observing whether the pointer overlaps with its mirror image when reading, the observer's correct vertical reading can be guaranteed, thereby ensuring the accuracy and reliability of the measurement value provided.

[0095] The measurement process of the meter 100 according to the embodiment of the present invention is described below in conjunction with specific embodiments.

[0096] like Figures 1 to 10As shown, the meter 100 according to the embodiment of the present invention includes a dial 10 , a measurement indicating device 20 , an upper limit indicating device 30 and a lower limit indicating device 40 . A scale 11 is provided on the dial 10, and a rotating shaft 50 is provided on the circular dial 10. The rotating shaft 50 can rotate relative to the dial 10, and one end of the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 respectively indicate each scale value, and the other ends of the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 are fixedly connected to the rotating shaft 50, and the pointer can rotate 360 ​​degrees synchronously on the dial 10 around the rotating shaft 50, wherein the upper limit indicating device 30 and the lower limit indicating device 40 are respectively distributed on both sides of the measurement indicating device 20, the upper limit indicating device 30 indicates the upper limit value at the upper limit position of the measurement indicating device 20, and the lower limit indicating device 40 indicates the lower limit value at the lower limit position of the measurement indicating device 20, and the upper limit value and the lower limit value together constitute the interval range of the measurement value, which meets the accuracy requirements of the user's measurement parameters.

[0097] When the meter 100 according to the embodiment of the present invention is measuring, before measuring a certain parameter, the required measurement accuracy range of the meter is analyzed and determined according to the needs of the actual use environment, and the two interval distances between one end of the upper limit value indicating device 30 and the lower limit value indicating device 40 and one end of the measuring indicating device 20 are adjusted to a suitable interval distance, and measurement is started. The measuring indicating device 20, the upper limit value indicating device 30 and the lower limit value indicating device 40 are synchronously rotated from the original scale value position to the measurement value position around the rotating shaft 50, the measuring indicating device 20 indicates the measurement value, the upper limit value indicating device 30 indicates the upper limit value of the measurement value, and the lower limit value indicating device 40 indicates the lower limit value of the measurement value, and the upper limit value and the lower limit value together constitute the interval range of the measurement value. When the user reads the value, if it is found that the measuring indicating device 20 has two different colors or two of the same color that do not overlap, it means that there is no vertical reading and the reading is incorrect. The reading is corrected again until it is observed that there is only one measuring indicating device 20, and then the measurement value, the upper limit value and the lower limit value are recorded, and the upper limit value and the lower limit value are used together as the interval range of the measurement value.

[0098] Therefore, by arranging a measurement indicating device 20, an upper limit indicating device 30 and a lower limit indicating device 40 on the dial 10, during measurement, the measurement indicating device 20, the upper limit indicating device 30 and the lower limit indicating device 40 can respectively indicate different scales 11, the measurement indicating device 20 can be used to indicate the measurement value, the upper limit indicating device 30 and the lower limit indicating device 40 can cooperate together to indicate the interval range of the measurement value indicated by the measurement indicating device 20, and meet the accuracy range required for actual measurement. When reading the numbers, the user can not only directly read the measurement value, but also directly read the interval value of the measurement value, which is more convenient to use, improves the accuracy of the measurement value, and can provide the user with effective information.

[0099] In addition, two measurement indicating devices 20 are provided on the dial 10, or the surface of the dial 10 is set as a reflective surface. In this way, when the user uses the instrument, if the user observes the two measurement indicating devices 20, he can realize that there is no vertical reading and the reading is incorrect. It is easy to find the reading error, and the user's irregular reading behavior when using the instrument is corrected in time, which effectively avoids inaccurate measurement values ​​caused by incorrect reading methods, makes the measurement process more rigorous, and improves the credibility and reliability of the measured parameter values.
