Description

Technical Field

[0001] This utility model relates to the field of length measurement and detection technology, and more specifically, it relates to a length measurement and detection device with a telescopic calibration probe. Background Technology

[0002] Length measurement and inspection refers to the technical means of accurately quantifying the linear dimensions (such as side length, diameter, and spacing) of objects using professional measuring devices. It is widely used in fields such as machining, construction, and electronic component manufacturing. It is a core link in ensuring the dimensional accuracy and assembly compatibility of products. To adapt to the measurement needs of objects of different sizes, length measurement and inspection devices with telescopic calibration probes have emerged. Through the telescopic adjustment of the calibration probe, it can flexibly adapt to the measurement range requirements in different measurement scenarios. At the same time, the calibration function of the probe ensures the accuracy of the measurement benchmark, which greatly improves the applicability and measurement reliability of the device.

[0003] However, in existing methods for straight-line measurement of right-angle structures, since the calibration probes are mostly single linear telescopic structures, they can only perform straight-line measurements in a fixed direction. When facing right-angle structures (such as the corner length of a workpiece), it is necessary to manually adjust the overall angle of the device to align with the measurement reference in another direction. This is not only cumbersome to operate, but also prone to causing the measurement reference to shift due to angular positioning deviation. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above situation and to overcome the defects of the prior art, this utility model provides a length measurement and detection device with a telescopic calibration probe, which aims to solve the problems in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this application provides the following technical solution: a length measurement and detection device with a telescopic calibration probe, comprising a measuring shell, a measuring plate slidably connected inside the measuring shell, multiple first scale lines and multiple second scale lines respectively etched on the upper right surface of the measuring shell and the upper right surface of the measuring plate, two symmetrical first balance grooves formed on the inner sidewall of the measuring shell, symmetrical first balance plates fixedly connected to the two sides of the measuring plate, two insertion holes formed on the upper surface of one open end of the measuring shell, multiple positioning grooves corresponding to the insertion holes formed on the upper surface of the measuring plate, a positioning head being engaged with the interior of each insertion hole and one of the positioning grooves, and two positioning heads... An auxiliary plate is fixedly connected to the top of the measuring plate. A storage groove is provided on the front of the measuring plate. A symmetrical second balance groove is provided on the inner side wall of the storage groove. A movable seat is slidably connected inside the storage groove. A symmetrical second balance plate is fixedly connected to the outer surface of the movable seat. Two symmetrical ball bearings are fixedly connected to the inner top wall and inner bottom wall of the movable seat. An adjustment shaft is fixedly connected to the inner ring of each pair of ball bearings. An angle opening and closing plate is fixedly connected to the outer surface of each adjustment shaft. Multiple third scale lines are etched on the upper surface of each angle opening and closing plate. A first calibration probe is fixedly connected to one side of the front of the measuring plate. A second calibration probe is fixedly connected to one end of each angle opening and closing plate.

[0006] The present invention is further configured such that the outer surface of each of the first balance plates is slidably connected to the interior of the first balance groove, and the outer surface of each of the second balance plates is slidably connected to the interior of the second balance groove.

[0007] The present invention is further configured such that two symmetrical balance rods are fixedly connected to the inner wall of the measuring shell, and two balance holes are opened on the front side of the measuring plate, and the interior of each balance hole is slidably connected to the outer surface of the balance rod.

[0008] The present invention is further configured such that a first magnet is fixedly connected to the inner bottom wall of each positioning groove, and a second magnet is fixedly connected to the bottom end of each positioning head, and each second magnet is attracted to the first magnet.

[0009] The present invention is further configured such that two anti-slip plates are fixedly connected to the outer surface of the auxiliary plate, and the two anti-slip plates are located above the auxiliary plate.

[0010] The present invention is further configured such that a rubber pad is provided on the outer side of the measuring shell, and the outer surface of the rubber pad is fixedly connected to the outer surface of the measuring shell.

[0011] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: 1. By sliding the measuring plate and the measuring shell in a straight line, the extension length of the measuring plate can be flexibly adjusted to increase the measurement range and adapt to the measurement needs of right-angled sides of different lengths. With the positioning structure, the adjusted measuring plate is stably locked. Combined with the scale lines on the measuring shell and the measuring plate, the size can be read, which can easily align the measurement of one side of the right angle without manually adjusting the overall angle of the device. At the same time, the two angle opening plates can slide out from the measuring plate storage slot and rotate, and cooperate with the probe on the measuring plate to fit the side of the right angle in the other direction. This avoids the tedious operation of repeatedly adjusting the overall angle of the existing device, realizes accurate measurement of the right angle in one direction, and improves the convenience and accuracy of measurement. 2. The two angle-opening plates are slidable within the measuring plate storage slot by a movable base, allowing for flexible adjustment of their positions. After sliding out, the angle-opening plates rotate around the adjustment structure, adapting to the side angles of different directions of the right angle. Combined with the linear sliding adjustment of the measuring shell and measuring plate, the two angle-opening plates can be respectively attached to the two sides of the right angle without moving the entire device. This, along with the scale lines on the measuring shell and measuring plate, enables synchronous measurement of the two sides of the right angle, avoiding the superposition of reference errors from segmented measurements. This solves the problems of cumbersome operation and low accuracy in measuring right angles in existing devices, ensuring the efficiency and reliability of multi-directional side measurement of right angle structures.

[0017] Please see Figures 1-7The measuring plate 5 is slidably connected to the measuring shell 3. Multiple first scale lines 2 and multiple second scale lines 6 are etched on the upper right surface of the measuring shell 3 and the upper right surface of the measuring plate 5, respectively. Two symmetrical first balance grooves 14 are formed on the inner sidewall of the measuring shell 3. Symmetrical first balance plates 15 are fixedly connected to both sides of the measuring plate 5. Two insertion holes 13 are formed on the upper surface of the opening end of the measuring shell 3. Multiple positioning grooves 7 corresponding to the insertion holes 13 are formed on the upper surface of the measuring plate 5. A positioning head 19 is engaged with the interior of one of the positioning grooves 7. An auxiliary plate 4 is fixedly connected to the top of the two positioning heads 19. The front of the measuring plate 5... A storage slot 26 is provided, and a symmetrical second balance slot 17 is provided on the inner side wall of the storage slot 26. A movable seat 11 is slidably connected inside the storage slot 26. A symmetrical second balance plate 21 is fixedly connected to the outer surface of the movable seat 11. Two symmetrical ball bearings 22 are fixedly connected to the inner top wall and inner bottom wall of the movable seat 11. An adjusting shaft 23 is fixedly connected to the inner ring of each pair of ball bearings 22. An angle opening and closing plate 9 is fixedly connected to the outer surface of each adjusting shaft 23. Multiple third scale lines 10 are etched on the upper surface of each angle opening and closing plate 9. A first calibration probe 24 is fixedly connected to one side of the front of the measuring plate 5. A second calibration probe 25 is fixedly connected to one end of each angle opening and closing plate 9.

[0018] Specifically, the extension length of the measuring plate 5 can be adjusted by sliding inside the measuring shell 3 to adapt to different right-angle side measurement needs. The first scale line 2 on the measuring shell 3 cooperates with the second scale line 6 on the measuring plate 5 to achieve length reading. The first balance plate 15 of the measuring plate 5 slides in the first balance groove 14 of the measuring shell 3 to prevent the measuring plate 5 from shifting during sliding. The insertion hole 13 of the measuring shell 3 and the positioning groove 7 of the measuring plate 5 are locked in place by the positioning head 19. The auxiliary plate 4 facilitates the operation of the positioning head 19. The measuring plate 5 has a storage groove 26. The second balance plate 21 of the movable seat 11 slides in the second balance groove 17 of the receiving groove 26 to stabilize the position of the movable seat 11. The ball bearing 22 of the movable seat 11 cooperates with the adjusting shaft 23 to allow the angle opening plate 9 to rotate. The third scale line 10 of the angle opening plate 9 assists in adjusting the angle. The first calibration probe 24 and the second calibration probe 25 are respectively attached to the two sides of the right angle. The right angle side can be measured without adjusting the overall angle of the device, which solves the problems of cumbersome operation and easy reference deviation of the existing device, and realizes accurate measurement of the right angle side.

[0019] Please see Figures 1-7 The outer surface of each first balance plate 15 is slidably connected to the interior of the first balance groove 14, and the outer surface of each second balance plate 21 is slidably connected to the interior of the second balance groove 17.

[0020] Specifically, by sliding the first balance plate 15 within the first balance groove 14, the sliding direction of the measuring plate 5 within the measuring housing 3 can be restricted, preventing the measuring plate 5 from swaying or tilting when sliding. The second balance plate 21, by sliding within the second balance groove 17, can constrain the movement trajectory of the moving seat 11 within the storage groove 26, preventing the moving seat 11 from deviating when sliding. The two work together to improve the stability of the sliding of the measuring plate 5 and the moving seat 11, ensuring the accurate position of the components during the measurement process, reducing measurement errors caused by sliding deviation, and ensuring the accuracy of right-angle side measurement.

[0021] Please see Figures 1-7 The measuring shell 3 is characterized by having two symmetrical balance rods 12 fixedly connected to its inner wall, and two balance holes 16 opened on the front side of the measuring plate 5, with the interior of each balance hole 16 being slidably connected to the outer surface of the balance rod 12.

[0022] Specifically, by sliding the balance rod 12 of the measuring shell 3 with the balance hole 16 of the measuring plate 5, the sliding direction of the measuring plate 5 can be further restricted from the front. This, together with the cooperation of the first balance plate 15 and the first balance groove 14, forms a double balance constraint, preventing the measuring plate 5 from warping or shifting during the sliding process. This ensures that the measuring plate 5 always slides in a straight line, avoiding scale reading deviations caused by unstable sliding of the measuring plate 5, and further improving the accuracy of right-angle side measurement.

[0023] Please see Figures 1-7 Each positioning groove 7 has a first magnet piece 8 fixedly connected to its inner bottom wall, and each positioning head 19 has a second magnet piece 20 fixedly connected to its bottom end. Each second magnet piece 20 is attracted to the first magnet piece 8.

[0024] Specifically, by attracting the first magnet 8 in the positioning groove 7 to the second magnet 20 of the positioning head 19, the firmness of the engagement between the positioning head 19 and the positioning groove 7 can be enhanced, preventing the positioning head 19 from accidentally falling off during the measurement process and causing the measuring plate 5 to shift. This ensures that the position of the measuring plate 5 is stable after locking, avoids the offset of the measurement reference caused by loose positioning, and ensures the stability and accuracy of the right-angle side measurement process.

[0025] Please see Figures 1-7 Two anti-slip plates 18 are fixedly connected to the outer surface of the auxiliary plate 4. The two anti-slip plates 18 are located above the auxiliary plate 4. A rubber pad 1 is provided on the outer side of the measuring shell 3. The outer surface of the rubber pad 1 is fixedly connected to the outer surface of the measuring shell 3.

[0026] Specifically, the anti-slip plate 18 on the auxiliary plate 4 can increase the friction between the hand and the auxiliary plate 4, making it easier for the operator to hold the auxiliary plate 4 to insert and remove the positioning head 19, and avoiding slippage during operation that affects positioning efficiency. The rubber pad 1 on the outside of the measuring shell 3 can enhance the comfort and friction when the hand holds the measuring shell 3, prevent the device from slipping accidentally, and at the same time, the rubber pad 1 can buffer the impact force when the device is collided, protect the measuring shell 3 and internal components, and improve the ease of use and service life of the device.

[0027] Working principle: In use, first stabilize the gripping device using the rubber pad 1 on the outside of the measuring shell 3, then slide the measuring plate 5 along the inside of the measuring shell 3 to match the length of the right-angle side. During the sliding process, the first balance plate 15 of the measuring plate 5 slides in the first balance groove 14 of the measuring shell 3, and the balance rod 12 of the measuring shell 3 slides in the balance hole 16 of the measuring plate 5. This double constraint ensures that the measuring plate 5 slides in a straight line without deviation. After adjusting to the appropriate length, grip the auxiliary plate 4 using the anti-slip plate 18 on the auxiliary plate 4, and insert the positioning head 19 through the insertion hole 13 of the measuring shell 3 into the positioning groove 7 of the measuring plate 5. The first magnet 8 in the positioning groove 7 is attracted and fixed to the second magnet 20 of the positioning head 19, locking the position of the measuring plate 5. Then, push the moving seat 11 on the measuring plate 5. The second balance plate 21 of the moving seat 11 slides within the storage slot 26 and slides within the second balance groove 17 of the storage slot 26 to maintain stability. After the moving seat 11 is adjusted to a suitable position, the angle opening and closing plate 9 is rotated by the cooperation of the ball bearing 22 and the adjusting shaft 23 inside the moving seat 11. The angle is calibrated by the third scale line 10 on the angle opening and closing plate 9, so that the first calibration probe 24 of the measuring plate 5 and the second calibration probe 25 of the angle opening and closing plate 9 respectively fit against the two sides of the right angle. Finally, the length of the right angle side is read by combining the first scale line 2 of the measuring shell 3 and the second scale line 6 of the measuring plate 5. The measurement can be completed without adjusting the overall angle of the device, which solves the problems of cumbersome operation and easy reference deviation of the existing device, and realizes accurate and stable measurement of the right angle side.

For all the fixed connections mentioned above, welding is preferred.
