[0035] Example 1
[0036] refer to Figure 1 and Figure 2 As shown, an embodiment of this application provides a lever micrometer 100, which includes a frame 110, a measuring component 120, a measuring anvil 130, and a limiting component 140.
[0037] Specifically, in combination Figure 2 and Figure 3 As shown, the measuring assembly 120 includes a sleeve 121, a rotating guide 122, and a measuring rod 123. The sleeve 121 is movably connected to the ruler frame 110 and defines a first receiving cavity 111. The rotating guide 122 is disposed in the first receiving cavity 111 and is threadedly connected to the sleeve 121. One end of the measuring rod 123 is connected to the rotating guide 122, and the end of the measuring rod 123 away from the rotating guide 122 corresponds to the mounting hole of the first receiving cavity 111. The measuring rod 123 is provided with a guide groove 1231. The anvil 130 and the measuring rod 123 are arranged opposite to each other. The rotating sleeve 121 drives the rotating guide 122 to rotate synchronously. The rotating guide 122 can drive the measuring rod 123 to move relative to each other to adjust the measuring rod 123, thereby adjusting the relative distance between the measuring rod 123 and the anvil 130. The item to be measured is placed between the measuring rod 123 and the anvil 130, so that the measuring rod 123 touches the item to be measured, so as to facilitate the measurement of the size of the item to be measured.
[0038] In this embodiment, the limiting component 140 includes a positioning member 141 and a limiting member 142. The positioning member 141 is disposed in the first receiving cavity 111, and one end of the positioning member 141 is movably connected to the sleeve 121. The positioning member 141 is provided with a limiting hole 1411, and the limiting member 142 passes through the limiting hole 1411. The limiting member 142 is movably engaged with the guide groove 1231, so that the rotating guide member 122 drives the measuring rod 123 to move movably through the positioning hole 1411. Component 141, correspondingly, is used to regulate the movement path of the measuring rod 123. The limiting component 142 passes through the limiting hole 1411 of the positioning component 141, so that the guide groove 1231 of the measuring rod 123 is engaged with the limiting component 142 of the limiting assembly 140, so as to limit the relative rotation of the measuring rod 123, avoid wear on the contact surface of the measuring rod 123, reduce the occurrence of axial offset or misalignment of the measuring rod 123, ensure the accuracy of measurement, and enable the measuring rod 123 to move relatively quickly in the axial direction.
[0039] It should be noted that the reference Figures 1 to 4 As shown, the lever micrometer 100 has a first direction. For example, the first direction is the length direction of the lever micrometer 100.
[0040] In one embodiment, alternatively, referencing Figure 4 and Figure 5 As shown, the positioning member 141 is a hollow tubular structure forming a limiting channel. The measuring rod 123 passes through the limiting channel along the first direction. The limiting channel is connected to the limiting hole 1411. The limiting channel of the positioning member 141 corresponds to the measuring rod 123, allowing the measuring rod 123 to pass through the limiting channel along the length direction of the lever micrometer 100. The limiting member 142 limits the relative rotation of the measuring rod 123 in the limiting channel through the limiting hole 1411. The limiting channel regulates the movement of the measuring rod 123 along the length direction of the lever micrometer 100, reducing the possibility of the measuring rod 123 deviating, and has a better technical effect.
[0041] Optionally, such as Figure 4 As shown, the centerline direction of the limiting hole 1411 is perpendicular to the extension direction of the limiting channel. That is, the centerline direction of the limiting hole 1411 is the extension direction of the limiting member 142, the extension direction of the limiting channel is the moving direction of the measuring rod 123, and the extension direction of the limiting member 142 is perpendicular to the moving direction of the measuring rod 123. The limiting member 142 is used to limit the rotation of the measuring rod 123 around the extension direction of the limiting channel. The limiting member 142 will not hinder or affect the movement of the measuring rod 123.
[0042] In one embodiment, alternatively, referencing Figure 3 andFigure 4 As shown, the lever micrometer 100 also includes an adjusting member 150 and a movable member 160. The frame 110 defines a second receiving cavity 112. The adjusting member 150 is inserted into the mounting port of the second receiving cavity 112, and the adjusting member 150 is movably connected to the anvil 130 through the movable member 160 to drive the anvil 130 to move relative to each other along a first direction. Correspondingly, the anvil 130, the movable member 160, and the adjusting member 150 are all disposed in the second receiving cavity 112 of the frame 110. The user can adjust the anvil 130 by rotating the adjusting member 150. The adjusting member 150 drives the anvil 130 to move relative to each other along the length direction of the lever micrometer 100 through the movable member 160, adjusting the relative distance between the anvil 130 and the measuring rod 123. The object to be measured is placed between the measuring rod 123 and the anvil 130 to facilitate the measurement of the size of the object to be measured.
[0043] In summary, the lever micrometer 100 drives the rotating guide 122 to rotate synchronously via the rotating sleeve 121. The rotating guide 122 can drive the measuring rod 123 to move relative to the measuring rod 123, thereby adjusting the relative distance between the measuring rod 123 and the anvil 130. The object to be measured is placed between the measuring rod 123 and the anvil 130, so that the measuring rod 123 abuts against the object to be measured, facilitating the measurement of the object's dimensions. The positioning element 141 is used to regulate the movement of the measuring rod 123. The moving path, the limiting member 142 passes through the limiting hole 1411 of the positioning member 141, so that the guide groove 1231 of the measuring rod 123 corresponds to the limiting member 142 of the limiting assembly 140, so as to limit the relative rotation of the measuring rod 123, avoid wear on the contact surface of the measuring rod 123, reduce the occurrence of axial offset or misalignment of the measuring rod 123, ensure the accuracy of measurement, and enable the measuring rod 123 to move faster in the axial direction, thereby improving the measurement efficiency of the lever micrometer 100.
[0044] Example 2
[0045] refer to Figures 1 to 3 As shown, an embodiment of this application provides another lever micrometer 100, which includes a frame 110, a measuring component 120, a measuring anvil 130, and a limiting component 140.
[0046] Specifically, in combination Figure 2 and Figure 3As shown, the measuring assembly 120 includes a sleeve 121, a rotating guide 122, and a measuring rod 123. The sleeve 121 is movably connected to the ruler frame 110 and defines a first receiving cavity 111. The rotating guide 122 is disposed within the first receiving cavity 111 and threadedly connected to the sleeve 121. One end of the measuring rod 123 is connected to the rotating guide 122, and the end of the measuring rod 123 away from the rotating guide 122 corresponds to the mounting hole in the first receiving cavity 111. The measuring rod 123 is provided with a guide groove 1231. The anvil 130 is disposed opposite to the measuring rod 123. The limiting component 140 includes a positioning member 141 and a limiting member 142. The positioning member 141 is disposed in the first receiving cavity 111, and one end of the positioning member 141 is movably connected to the sleeve 121. The positioning member 141 is provided with a limiting hole 1411, and the limiting member 142 passes through the limiting hole 1411. The limiting member 142 is movably engaged with the guide groove 1231, so that the rotating guide member 122 drives the measuring rod 123 to move movably through the positioning member 141. Correspondingly, by rotating the sleeve 121, the rotating guide member 122 is driven to rotate synchronously, and the rotating guide member 122 can drive the measuring rod 123 to move relatively to adjust the measuring rod 123, thereby adjusting the measurement. The purpose of the relative distance between the measuring rod 123 and the anvil 130 is to place the object to be measured between the measuring rod 123 and the anvil 130, so that the measuring rod 123 abuts against the object to be measured, so as to facilitate the measurement of the size of the object to be measured. The positioning member 141 is used to regulate the movement path of the measuring rod 123. The limiting member 142 passes through the limiting hole 1411 of the positioning member 141, so that the guide groove 1231 of the measuring rod 123 corresponds to the limiting member 142 of the limiting assembly 140, so as to limit the relative rotation of the measuring rod 123, avoid wear on the contact surface of the measuring rod 123, reduce the occurrence of axial offset or misalignment of the measuring rod 123, ensure the accuracy of measurement, and enable the measuring rod 123 to move relatively quickly in the axial direction.
[0047] It should be noted that the reference Figures 1 to 4 As shown, the lever micrometer 100 has a first direction. For example, the first direction is the length direction of the lever micrometer 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the parts in the lever micrometer 100 and should not be construed as limitations on this application.
[0048] In one embodiment, alternatively, referencing Figure 4 and Figure 5As shown, the positioning member 141 is a hollow tubular structure forming a limiting channel. The measuring rod 123 passes through the limiting channel along a first direction. The limiting channel is connected to the limiting hole 1411. The limiting channel of the positioning member 141 corresponds to the measuring rod 123, allowing the measuring rod 123 to pass through the limiting channel along the length direction of the lever micrometer 100. The limiting member 142 limits the relative rotation of the measuring rod 123 within the limiting channel through the limiting hole 1411. The limiting channel regulates the movement of the measuring rod 123 along the length direction of the lever micrometer 100, reducing the possibility of the measuring rod 123 deviating, thus achieving better technical results. For example, the limiting channel is a cylindrical cavity, and the shape and size of the measuring rod 123 are adapted to the limiting channel of the cylindrical cavity.
[0049] Optionally, such as Figure 4 As shown, the centerline of the limiting hole 1411 is perpendicular to the extension direction of the limiting channel. That is, the centerline of the limiting hole 1411 is the extension direction of the limiting member 142, and the extension direction of the limiting channel is the moving direction of the measuring rod 123. The extension direction of the limiting member 142 is perpendicular to the moving direction of the measuring rod 123. The limiting member 142 is used to limit the rotation of the measuring rod 123 around the extension direction of the limiting channel. The limiting member 142 will not hinder or affect the movement of the measuring rod 123.
[0050] In this embodiment, optionally, in combination with Figure 5 and Figure 6 As shown, the end of the limiting member 142 is a tapered structure, and the guide groove 1231 extends along the first direction. The end of the limiting member 142 engages with the groove wall of the guide groove 1231. The end of the tapered limiting member 142 corresponds to the groove wall of the guide groove 1231. The guide groove 1231 extends along the first direction to facilitate the relative movement of the measuring rod 123 along the first direction, and the limiting member 142 limits and regulates the relative rotation of the measuring rod 123. Since the rotation of the measuring rod 123 avoids wear on the contact surface of the measuring rod 123, the measuring rod 123 can move faster along the axial direction to amplify the travel of the measuring rod 123, achieve the purpose of rapid measurement, and thus improve measurement efficiency.
[0051] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, the lever micrometer 100 also includes an adjusting member 150 and a movable member 160. The frame 110 defines a second receiving cavity 112. The adjusting member 150 is inserted into the mounting port of the second receiving cavity 112, and the adjusting member 150 is movably connected to the anvil 130 through the movable member 160 to drive the anvil 130 to move relative to each other along a first direction. Correspondingly, the anvil 130, the movable member 160, and the adjusting member 150 are all disposed in the second receiving cavity 112 of the frame 110. The user can adjust the anvil 130 by rotating the adjusting member 150. The adjusting member 150 drives the anvil 130 to move relative to each other along the length direction of the lever micrometer 100 through the movable member 160, adjusting the relative distance between the anvil 130 and the measuring rod 123, and placing the object to be measured between the measuring rod 123 and the anvil 130.
[0052] Optionally, refer to Figure 4 As shown, one end of the movable member 160 abuts against the adjusting member 150, and the end of the movable member 160 away from the adjusting member 150 engages with the limiting groove 131 of the anvil 130. The movable member 160 rotates around the rotation axis. In other words, the adjusting member 150 abuts against the movable member 160 and drives the movable member 160 to rotate around the rotation axis, so that the movable member 160 engages with the limiting groove 131 of the anvil 130 and drives the anvil 130 to move, so that the anvil 130 moves relative to the other within a preset range, thereby achieving the purpose of adjusting the position of the anvil 130.
[0053] Optionally, such as Figure 4 As shown, the adjusting member 150 is threadedly connected to the ruler frame 110. The adjusting member 150 drives the anvil 130 to move relative to it via the movable member 160. The direction of movement of the adjusting member 150 is opposite to the direction of movement of the anvil 130. Correspondingly, the adjusting member 150 moves relative to the movable member 160 along a first direction to push the movable member 160 to move, so that the movable member 160 drives the anvil 130 to move during rotation. Since the two opposite ends of the movable member 160 are respectively connected to the adjusting member 150 and the anvil 130, when the movable member 160 rotates relative to the movable member, the direction of movement of the adjusting member 150 is opposite to the direction of movement of the anvil 130. Exemplarily, the direction of rotation of the movable member 160 is clockwise.
[0054] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, the lever micrometer 100 also includes a sensing element and a control element. The sensing element is connected to the anvil 130, and the control element is electrically connected to the output terminal of the sensing element. The sensing element senses and measures the position of the anvil 130. The control element receives the output signal from the output terminal of the sensing element, processes the output signal, and outputs measurement data. Exemplarily, the sensing element is a grating encoder, a linear or angular position sensor based on grating technology. It achieves accurate measurement of object position through photoelectric conversion and features high resolution, non-contact measurement, strong anti-interference capability, and fast response speed.
[0055] It is understandable that the control unit can be an integrated circuit chip with signal processing capabilities. The aforementioned control unit can be a general-purpose processor, including a central processing unit (CPU), or it can be a microcontroller, microcontroller unit, complex programmable logic device (MCU), field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), embedded ARM, etc. The control unit also includes memory to store program instructions that can be executed by the integrated circuit chip; for example, the memory can be integrated within the chip.
[0056] Optionally, combined Figure 1 and Figure 2 As shown, the lever micrometer 100 also includes a display screen 170, which is mounted on the frame 110 and electrically connected to the control unit. The display screen 170 facilitates a more intuitive and convenient display of the measurement readings of the lever micrometer 100, making it easy to view the measurement readings. By directly displaying the measurement values on the screen, the measurement speed and accuracy are improved, human error is reduced, and the user experience is enhanced.

[0059] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0060] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
