Description

Technical Field

[0001] This utility model belongs to the field of vernier caliper technology, and specifically relates to a digital vernier caliper with voice broadcast. Background Technology

[0002] Digital vernier calipers, as a high-precision length measuring tool, play an indispensable role in many fields such as machining, scientific research, and quality inspection. Utilizing electronic technology, they convert the measured displacement into a digital signal and display it intuitively on a screen, improving measurement accuracy and efficiency. Compared to traditional vernier calipers, reading is more convenient and accurate, making them popular among professionals.

[0003] However, when using digital vernier calipers for vertical measurements at heights, positioning the vernier becomes inconvenient. Due to gravity, the vernier easily slides downwards without proper fixation, making it difficult for the surveyor to obtain stable and accurate measurements. Although current digital vernier calipers are equipped with locking screws to secure the vernier, in practice, when the surveyor lifts the calipers for measurements at heights, the arm needs to extend upwards, making it difficult to accurately reach and operate the screws. Even if the screws are reached, the accuracy and stability of the operation are difficult to guarantee, resulting in the vernier still not being effectively positioned.

[0004] To address the above issues, this application proposes a digital vernier caliper with voice prompts. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a digital vernier caliper with voice-guided operation, achieved through the design of a high-positioning component. The rotation of the rotating wheel drives the lead screw to rotate synchronously within the central slot. The lead screw and the inner slider are connected by a threaded connection; the rotation of the lead screw causes the inner slider to slide stably along the central slot. As the inner slider slides, the upper and lower push plates connected to it push the vernier upwards until it reaches the desired measurement position. This design not only enables the vernier to rise but also allows it to be positioned correctly after reaching the designated location. It effectively prevents the vernier from sliding downwards due to gravity when measuring at heights, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A digital vernier caliper with voice broadcast capability includes: a caliper body, a high-positioning component on one side of the caliper body; the high-positioning component includes a central through groove in the middle of the caliper body, an inner slider inside the central through groove, connecting plates fixedly connected to both sides of the inner slider, an upper push plate fixedly connected to the upper end of the connecting plates, and a lower push plate fixedly connected to the lower end of the connecting plates; a screw hole is opened in the center of the inner slider, a lead screw is threaded into the screw hole, a wheel cavity is opened on the rear side of the caliper body, a rotating wheel is provided in the wheel cavity, and a positioning port is opened on the rear surface of the caliper body, a magnetic block is provided in the positioning port.

[0008] Through the above technical solution, the rotation of the rotary wheel can drive the lead screw to rotate synchronously. The lead screw and the screw hole utilize a threaded transmission principle, allowing the lead screw to rotate smoothly within the screw hole, thereby driving the inner slider to slide smoothly along the central through groove. During its movement, the inner slider simultaneously applies thrust to the upper and lower push plates via the connecting plate.

[0009] In a preferred embodiment, both the rotating wheel and the magnetic block are made of magnetic material. The rotating wheel is fixedly connected to the lead screw, and the magnetic block is fixedly connected to the ruler body via a connecting rope.

[0010] Using the above technical solution, the magnetic block is picked up and inserted into the positioning port. Once inserted, it can quickly form a magnetic connection with the rotating wheel, fixing the rotating wheel in the current position. This positioning method ensures that the rotating wheel will not rotate due to external vibrations or accidental touches during the measurement process.

[0011] In a preferred embodiment, the length of the upper push plate is greater than the length of the lower push plate, and both the upper push plate and the lower push plate are L-shaped structures, with the upper push plate and the lower push plate being mirror images of each other.

[0012] Through the above technical solution, the thrust of the upper push plate can directly act on the vernier, while the lower push plate moves the vernier by pushing the fine-tuning roller. This dual-push structure design allows the vernier to obtain more stable and reliable support when measuring at heights, preventing the vernier from sliding downwards.

[0013] In a preferred embodiment, a vernier is slidably disposed on one side of the ruler body, two sets of inner diameter measuring claws are disposed above the ruler body, and two sets of outer diameter measuring claws are disposed below the ruler body. The two sets of inner diameter measuring claws and the two sets of outer diameter measuring claws are respectively fixedly connected to the ruler body and the vernier.

[0014] With the above technical solution, the vernier can slide on the outside of the ruler body, thereby enabling the measurement of the size of an object through the inner diameter measuring jaw or the outer diameter measuring jaw.

[0015] In a preferred embodiment, a digital display screen is mounted on the front of the vernier, a unit conversion key is mounted on the top of the front of the vernier, a power switch is mounted on the lower left side of the front of the vernier, and a zeroing / reset key is mounted on the lower right side of the front of the vernier.

[0016] Through the above technical solution, the digital display screen can display the size value of the measured object.

[0017] In a preferred embodiment, a fastening screw is installed above the vernier, a battery compartment cover is provided to the right of the unit conversion key, the battery compartment cover is snapped onto the front of the vernier, a voice button is installed on the upper right side of the front of the vernier, a fine-tuning roller is installed on the lower right side of the vernier, and a depth rod is fixedly connected to the right end of the ruler.

[0018] In a preferred embodiment, a voice module is installed inside the vernier, a miniature speaker is installed at the rear of the vernier, a speaker opening is provided on the back of the vernier, and a tail screw is installed at the tail end of the ruler.

[0019] Using the above technical solution, the miniature speaker can convert the measured audio signal into sound and play it out through the speaker opening on the back of the vernier.

[0020] In a preferred embodiment, the voice module is electrically connected to the digital display screen. The voice module includes a microcontroller, an audio decoding chip, a miniature speaker, and a storage chip. A battery is installed inside one side of the cursor, and the position of the battery corresponds to the position of the battery compartment cover. The battery is electrically connected to the voice module and the digital display screen via a power switch. The unit conversion key, voice button, and zero reset key are electrically connected to the digital display screen. A displacement sensor is installed inside the cursor and is electrically connected to the digital display screen.

[0021] Using the above technical solution, the displacement sensor installed inside the vernier will detect the displacement change of the vernier relative to the scale in real time. The displacement sensor transmits the measured displacement data to the digital display screen.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are:

[0023] 1. When performing measurements at heights, digital vernier calipers often suffer from inaccuracies due to difficulties in vernier positioning. To address this, we have designed a special high-positioning component. A rotating wheel is located at the rear of the caliper. When measurements need to be performed at heights, rotating this wheel causes the lead screw to rotate synchronously within a central slot. The lead screw and the inner slider are connected by a threaded connection, and the rotation of the lead screw causes the inner slider to slide stably along the central slot. As the inner slider slides, the upper and lower push plates connected to it move accordingly. When they move upwards, they steadily push the vernier up until it reaches the desired measurement position. This design not only enables the vernier to rise but also positions it after reaching the designated location, effectively preventing the vernier from sliding downwards due to gravity during measurements at heights, ensuring the stability of the measurement process and the accuracy of the measurement results.

[0024] 2. By designing a voice module, after measuring an object with a vernier caliper, pressing the voice button will read out the measured value through a miniature speaker, making it easier for the measuring personnel to read and record the value, thus improving the ease of operation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 5 A digital vernier caliper with voice broadcast capability includes: a caliper body 6, with a high positioning component 15 on one side of the caliper body 6; the high positioning component 15 includes a central through groove 152 in the middle of the caliper body 6, an inner slider 154 inside the central through groove 152, connecting plates 155 fixedly connected to both sides of the inner slider 154, an upper push plate 156 fixedly connected to the upper end of the connecting plate 155, and a lower push plate 157 fixedly connected to the lower end of the connecting plate 155; a screw hole is opened in the center of the inner slider 154, and a lead screw 153 is threaded into the screw hole; a wheel cavity 151 is opened on the rear side of the caliper body 6, and a rotating wheel 158 is provided in the wheel cavity 151; a positioning port is opened at the rear of the upper surface of the caliper body 6, and a magnetic block 159 is provided in the positioning port.

[0034] The rotation of the rotary wheel 158 drives the lead screw 153 to rotate synchronously. The lead screw 153 and the screw hole adopt the principle of threaded transmission. The lead screw 153 rotates smoothly in the screw hole, thereby driving the inner slider 154 to slide smoothly along the central through groove 152. During the movement, the inner slider 154 applies a pushing force to the upper push plate 156 and the lower push plate 157 simultaneously through the connecting plate 155.

[0035] Both the rotating wheel 158 and the magnetic block 159 are made of magnetic material. The rotating wheel 158 is fixedly connected to the lead screw 153, and the magnetic block 159 is fixedly connected to the ruler body 6 through the connecting rope 1510.

[0036] Pick up the magnetic block 159 and insert it into the positioning port. Once inserted, it can quickly form a magnetic connection with the rotating wheel 158, fixing the rotating wheel 158 in the current position. This positioning method ensures that the rotating wheel 158 will not rotate due to external vibration or accidental touch during the measurement process.

[0037] The length of the upper push plate 156 is greater than the length of the lower push plate 157. Both the upper push plate 156 and the lower push plate 157 are L-shaped structures and are mirror images of each other.

[0038] The pushing force of the upper push plate 156 can directly act on the vernier 14, while the lower push plate 157 pushes the vernier 14 to move by pushing the fine-tuning roller 13. This dual-push structure design allows the vernier 14 to obtain more stable and reliable support when measuring at a height, preventing the vernier 14 from sliding downward.

[0039] A vernier 14 is slidably mounted on one side of the ruler body 6. Two sets of inner diameter measuring claws 1 are provided above the ruler body 6, and two sets of outer diameter measuring claws 9 are provided below the ruler body 6. The two sets of inner diameter measuring claws 1 and the two sets of outer diameter measuring claws 9 are respectively fixedly connected to the ruler body 6 and the vernier 14.

[0040] The vernier 14 can slide on the outside of the scale body 6, thereby enabling the measurement of the size of an object by means of the inner diameter measuring jaw 1 or the outer diameter measuring jaw 9.

[0041] The vernier 14 has a digital display screen 4 mounted on its front, a unit conversion key 2 mounted on the top of the front of the vernier 14, a power switch 10 mounted on the lower left side of the front of the vernier 14, and a zeroing / reset key 11 mounted on the lower right side of the front of the vernier 14.

[0042] The digital display screen 4 can display the dimensions of the measured object.

[0043] A fastening screw 3 is installed on the top of the vernier 14. A battery compartment cover 12 is located on the right side of the unit conversion key 2. The battery compartment cover 12 is fastened and installed on the front of the vernier 14. A voice button 5 is installed on the upper right side of the front of the vernier 14. A fine-tuning roller 13 is installed on the lower right side of the vernier 14. A depth rod 8 is fixedly connected to the right end of the ruler 6.

[0044] The vernier 14 is equipped with a voice module, a miniature speaker is installed at the rear of the vernier 14, a speaker opening is provided on the back of the vernier 14, and a ruler tail screw 7 is installed at the end of the ruler body 6.

[0045] The miniature speaker can convert the measured audio signal into sound and play it out through the speaker opening on the back of the vernier 14.

[0046] The voice module is electrically connected to the digital display screen 4. The voice module includes a microcontroller, an audio decoding chip, a miniature speaker, and a storage chip. A battery is installed inside the vernier 14 on one side, and the position of the battery corresponds to the position of the battery compartment cover 12. The battery is electrically connected to the voice module and the digital display screen 4 through the power switch 10. The unit conversion key 2, the voice button 5, and the zero reset key 11 are electrically connected to the digital display screen 4. A displacement sensor is installed inside the vernier 14, and the displacement sensor is electrically connected to the digital display screen 4.

[0047] The displacement sensor installed inside the vernier 14 senses the displacement change of the vernier 14 relative to the scale 6 in real time. The displacement sensor transmits the measured displacement data to the digital display screen 4.

[0048] In practical use, the working principle of this utility model is as follows:

[0049] When using this vernier caliper for dimensional measurement, first turn on the power switch 10. The battery powers the voice module and digital display 4, putting them into operation. To measure the outer diameter of an object, place the object between the outer diameter measuring jaws 9; to measure the inner diameter, use the inner diameter measuring jaws 1. Then, move the vernier 14 outside the scale body 6, bringing the measuring jaws into contact with the object. The displacement sensor installed inside the vernier 14 senses the displacement change of the vernier 14 relative to the scale body 6 in real time. The displacement sensor transmits the measured displacement data to the digital display 4. After internal calculation and processing, the digital display 4 displays the measured object's dimensional value. When the measuring operator wants to obtain the measurement result via voice broadcast, simply press the voice button 5. Since the voice module is electrically connected to the digital display 4, the dimensional value displayed on the digital display 4 is transmitted to the voice module. After receiving this numerical information, the microcontroller in the voice module coordinates the operation of the audio decoding chip and the storage chip. The memory chip pre-stores voice data such as numbers and units. The audio decoding chip, according to instructions from the microcontroller, retrieves the corresponding voice data from the memory chip, decodes it, generates an audio signal, and transmits it to a miniature speaker installed at the rear of the vernier 14. The miniature speaker converts the audio signal into sound, which is then played through a speaker opening on the back of the vernier 14, thus enabling voice announcement of the measured values, facilitating reading and recording by the measurement personnel.

[0050] When conducting measurements at height, the operator can rotate the rotating wheel 158, which drives the lead screw 153 to rotate synchronously. The lead screw 153 and the screw hole utilize a threaded transmission principle, allowing the lead screw 153 to rotate smoothly within the screw hole, thereby driving the inner slider 154 to slide smoothly along the central through groove 152. During its movement, the inner slider 154 applies a pushing force to both the upper push plate 156 and the lower push plate 157 via the connecting plate 155. The upper push plate 156 directly acts on the vernier 14, while the lower push plate 157 pushes the vernier 14 by driving the fine-tuning roller 13. This dual-push structure design provides the vernier 14 with more stable and reliable support during measurements at height, preventing it from sliding downwards and effectively ensuring the stability of the measurement process and the accuracy of the measurement results. During the measurement process, to prevent the rotating wheel 158 from rotating accidentally and affecting the measurement accuracy, the operator only needs to pick up the magnetic block 159 and insert it into the positioning port. Once inserted into the positioning port, it can quickly form a magnetic connection with the rotating wheel 158, fixing the rotating wheel 158 in the current position. This positioning method ensures that the rotating wheel 158 will not rotate due to external vibration or accidental contact during the measurement process, providing a stable operational guarantee for high-altitude measurements.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
