[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1-5 , the present invention is further introduced in detail.

[0027] An embodiment of the present invention provides an Internet of Things vernier caliper, comprising a ruler body 1, a vernier scale 2, a digital display module 3, a first outer measuring jaw 4 and a second outer measuring jaw 5, the vernier scale 2 is slidably mounted on the ruler body 1, the first outer measuring jaw 4 is mounted on the ruler body 1, the second outer measuring jaw 5 is mounted on the vernier scale 2, the digital display module 3 is mounted on the vernier scale 2, the digital display module 3 displays and records the measured value, and also includes a horizontal adjustment unit 6 fixedly mounted on the first outer measuring jaw 4, the horizontal adjustment unit 6 is used to adjust the part to be measured to be parallel to the ruler body 1.

[0028] Specifically, the ruler body 1 of the vernier caliper is usually a metal bar with a scale, providing a basic measurement unit (millimeter or inch), and each scale on the ruler body 1 is used to represent the main data of the measurement, wherein the vernier ruler 2 is slidably installed on the ruler body 1, and the vernier ruler 2 has finer scales. When the first outer measuring jaw 4 and the second outer measuring jaw 5 clamp the object, combined with the scales on the ruler body 1 and the vernier ruler 2, the length of the object can be directly read, wherein the digital display module 3 includes a display screen and a built-in control unit. When the first outer measuring jaw 4 and the second outer measuring jaw 5 clamp the object, the display screen on the digital display module 3 directly displays the length of the object, eliminating the reading time of the staff, and the digital display module 3 is connected to the computer and mobile phone terminals for communication. After completing the measurement of the object, the digital display module 3 is powered off, and the measured data is transmitted to the computer and mobile phone terminals to save the measurement information.

[0029] Obviously, when the vernier caliper is used to measure objects with sharp ends such as needles and nails, the vernier caliper does not hold the object firmly due to the small contact area between the sharp end of the object and the vernier caliper, and the object is prone to tilt. Therefore, when clamping and measuring the object, it is necessary to manually adjust the object's placement angle repeatedly until it is horizontal in order to measure an accurate value.

[0030] In order to solve the above problem, in the present embodiment, a horizontal adjustment unit 6 is fixedly mounted on the first outer measuring jaw 4 , and the horizontal adjustment unit 6 is used to adjust the part to be measured and the ruler body 1 to be parallel.

[0031] Specifically, when it is necessary to measure the length of objects with sharp ends such as needles and nails, the object to be measured is manually placed on the horizontal adjustment unit 6, and the horizontal adjustment unit 6 adjusts the object to be detected to a horizontal placement state (the horizontal placement state is also a state parallel to the ruler body 1), and then the first outer measuring claw 4 and the second outer measuring claw 5 clamp the two ends of the object to be measured, and the measured value is displayed on the display screen of the digital display module 3, thereby completing the measurement of the length of the object.

[0032] Preferably, the horizontal adjustment unit 6 includes an adjustment plate 61, a horizontal slide groove 62 is provided on the adjustment plate 61, one end of the adjustment plate 61 is fixedly connected to the first outer measuring claw 4, a slider 63 is fixedly installed on the second outer measuring claw 5, the slider 63 is inserted into the horizontal slide groove 62, and a first fixing portion 64 and a second fixing portion 65 are also provided in the horizontal slide groove 62, and the first fixing portion 64 and the second fixing portion 65 are both located between the first outer measuring claw 4 and the second outer measuring claw 5.

[0033] Specifically, the adjustment plate 61 is arranged parallel to the ruler body 1, and the horizontal slide groove 62 is also arranged parallel to the ruler body 1. When it is necessary to measure the length of an object, the staff puts the object to be measured into the first fixing part 64 and the second fixing part 65. The first fixing part 64 and the second fixing part 65 both fix the object to be measured, which is equivalent to the object to be measured being fixed at two points. Due to the principle of two points and one line, the first fixing part 64 and the second fixing part 65 are both in the horizontal slide groove 62. At this time, the object to be measured fixed by the first fixing part 64 and the second fixing part 65 is also parallel to the ruler body 1. At this time, relative to the ruler body 1, the object to be measured remains in a horizontal position. Then the staff pushes the vernier ruler 2 so that the first outer measuring claw 4 and the second outer measuring claw 5 clamp the two ends of the object to be detected, and then observes the value on the digital display module 3 to complete the length detection of the object to be detected, thereby avoiding the situation where the object tilts when measuring the length of an object with a sharp end, thereby affecting the accuracy of the measurement data.

[0034] Preferably, the first fixing portion 64 includes a sliding block 641 slidably installed in the horizontal sliding groove 62, the sliding block 641 is connected to the first outer measuring claw 4 by connecting the straight rod 642, and a fixing seat 643 is detachably installed on the sliding block 641, and the fixing seat 643 is used to fix the object to be measured. The first fixing portion 64 and the second fixing portion 65 have the same structure, and the second fixing portion 65 is connected to the second outer measuring claw 5 by connecting the straight rod 642; a placement notch 644 is provided on the fixing seat 643, and a clamping portion 66 is provided in the placement notch 644, and the clamping portion 66 is used to clamp the object to be detected and maintain the object to be detected in a horizontal placement state; the clamping portion 66 includes two groups of clamping springs 661 arranged at intervals in the upper and lower parts, and the two groups of clamping springs 661 are arranged relatively to clamp the object to be detected.

[0035] Specifically, by providing a detachable fixing seat 643, objects to be measured of different sizes can be fixed. In this embodiment, the fixing seat 643 and the sliding block 641 are detachably connected by a threaded connection, and the sliding block 641 is connected to the first outer measuring claw 4 by a connecting straight rod 642. At this time, there is a length of the connecting straight rod 642 between the fixing seat 643 and the first outer measuring claw 4, that is, the fixing seat 643 and the first outer measuring claw 4 are spaced apart. Similarly, because the first fixing portion 64 and the second fixing portion 65 have the same structure, the second fixing portion 643 is 5 is also spaced apart from the fixing seat 643 and the second outer measuring claw 5. At this time, the two fixing seats 643 clamp the side wall of the object to be measured to avoid interference with the first outer measuring claw 4 and the second outer measuring claw 5, which would cause inaccurate measurement data. In this embodiment, the two clamping springs 661 are spaced apart up and down. When the object to be detected needs to be clamped, the staff presses the side wall of the object to be detected into the fixing seat 643. The two clamping springs 661 on the fixing seat 643 clamp the side wall of the object to be detected, thereby completing the fixing of the object to be detected.

[0036] Obviously, when the clamping spring 661 is used to clamp an object, the object is clamped by the elastic deformation of the clamping spring 661. When the width of the object is too large, the clamping spring 661 needs to undergo a larger deformation to ensure the clamping of the object. When the clamping spring 661 undergoes repeated loading and unloading during the clamping process, the stress generated can easily cause cracks to form inside the material of the clamping spring 661. As time goes by, these cracks can easily expand and cause fatigue damage to the clamping spring 661, making it impossible for the clamping spring 661 to restore its original shape, affecting the clamping of the object to be detected.

[0037] In order to solve the above problem, the placement gap 644 is divided into an adjustment sensing section 645 and a clamping section 646 from front to back. The clamping spring piece 661 is arranged in the clamping section 646. A trigger unit 67 is arranged in the adjustment sensing section 645. The trigger unit 67 moves based on the diameter and width of the object to be detected. An adjustment component 68 is also arranged on the fixed seat 643. The adjustment component 68 adjusts the distance between the two groups of clamping spring pieces 661 based on the movement of the trigger unit 67 to adapt to objects of different sizes to be detected; the trigger unit 67 includes The adjusting assembly 68 comprises two trigger push rods 671 which are arranged opposite to each other, and the two trigger push rods 671 correspond to the two clamping springs 661 respectively. The trigger push rods 671 are connected to the fixing seat 643 through the connecting spring 672. The adjusting assembly 68 comprises two connecting rods 681 which correspond to the two trigger push rods 671 one by one respectively. Both ends of the connecting rods 681 are wedge-shaped structures. One end of the connecting rod 681 is wedge-fitted with the trigger push rod 671, and the other end of the connecting rod 681 is wedge-fitted with the clamping springs 661.

[0038] Specifically, the interior of the fixing seat 643 is hollow, and two adjustment slots 647 are provided on the fixing seat 643. The two adjustment slots 647 correspond to the two clamping springs 661 one by one. One end of the trigger push rod 671 extends into the adjustment slot 647. One end of the trigger push rod 671 located in the adjustment slot 647 is connected to the fixing seat 643 through a connecting spring 672. The other end of the trigger push rod 671 is located in the adjustment sensing section 645 on the fixing seat 643, and one end of the trigger push rod 671 located in the adjustment sensing section 645 is also wedge-shaped. In addition, in order to facilitate the adjustment of the clamping springs 661, Position, in this embodiment, the clamping spring 661 is fixedly installed on the spring seat 662, and the spring seat 662 is composed of a frame and a rod body. The clamping spring 661 is fixedly installed on the frame, and the frame and the rod body are fixedly connected. The rod body of the spring seat 662 is connected to the adjusting groove 647 through a reset spring 663, and a avoidance notch 664 is opened on the rod body of the spring seat 662. The avoidance notch 664 is used for the connecting rod 681 to pass through, and an extrusion wedge 665 is fixedly installed on the end of the rod body of the avoidance notch 664 away from the clamping spring 661, and the extrusion wedge 665 is wedge-matched with the end of the connecting rod 681.

[0039] When installing the object to be detected, the staff presses the object to be detected into the placement notch 644 on the fixed seat 643. When the object to be detected passes through the adjustment sensing section 645 of the placement notch 644, the object to be detected squeezes the wedge-shaped surface of the trigger push rod 671. The trigger push rod 671 moves toward the adjustment groove 647 of the fixed seat 643 under the squeezing of the object to be detected. At this time, the connecting spring 672 connected to the trigger push rod 671 shrinks and deforms, accumulating elastic potential energy, and as the trigger push rod 671 moves, the trigger push rod 671 squeezes the wedge-shaped end of the connecting rod 681, pushing the connecting rod 681 to slide in the direction of the clamping spring 661. When the connecting rod 681 slides and the end of the connecting rod 681 passes through the avoidance notch 664, the connecting rod 681 and the extrusion wedge block 665 are wedge-fitted, and under the extrusion of the connecting rod 681, the spring plate seat 662 on which the clamping spring plate 661 is installed slides toward the direction of the adjustment groove 647, so that the two clamping spring plates 661 are separated from each other. Therefore, when clamping an object with a larger width, the two clamping spring plates 661 can clamp the object to be measured with a smaller deformation amplitude, thereby protecting the clamping spring plates 661 and avoiding damage to the clamping spring plates 661 due to excessive deformation, which affects the normal clamping of the object to be detected.

[0040] Obviously, in order to facilitate the object to be detected to leave the placement notch 644 of the fixed seat 643, preferably, in the present embodiment, the trigger push rod 671 is located at the end of the placement notch 644 and presents a triangular structure, that is, no matter whether the object to be detected enters or leaves the placement notch 644, the trigger push rod 671 always has an inclined surface that cooperates with the object to be detected, ensuring that under the squeezing of the object to be detected, the trigger push rod 671 can always move toward the adjustment slot 647 on the fixed seat 643, thereby facilitating the disassembly of the object to be detected, thereby indirectly improving the detection efficiency of the object.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
