Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, and in particular to a dental orthodontic measuring rod. Background Technology

[0002] In the field of dentistry, accurate data measurement before orthodontic treatment plays a crucial role. However, traditional tooth measurement methods are not only complex to operate, but also often rely on the doctor's subjective judgment, which may affect the accuracy of the measurement results. On the one hand, many tools are complex in design and cumbersome to operate, which not only increases the workload of doctors, but may also affect the accuracy of measurement results. On the other hand, these tools often can only measure certain specific dimensions of teeth, such as length and width, and cannot fully reflect the complex morphology of teeth such as tilting and rotation, thus limiting the development of personalized orthodontic plans.

[0003] To overcome the shortcomings of existing technologies, a tool is needed that can conveniently, quickly, and accurately measure teeth in multiple dimensions to meet the high requirements for data accuracy in orthodontic treatment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a dental orthodontic measuring rod that is simple to operate, allows for direct reading, and provides comprehensive measurements, thus solving some of the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a dental orthodontic measuring rod, including an outer rod, a bidirectional threaded rod rotatably installed in the middle of the inner part of the outer rod, two sets of symmetrical movable sleeves threadedly sleeved on the bidirectional threaded rod near the front and rear sides, a limiting block fixedly connected to the upper and lower ends of the movable sleeves, a sliding sleeve slidably sleeved on the outer side of the outer rod near the front and rear sides, the movable sleeves being fixedly connected to the sliding sleeves through the limiting blocks, a movable retaining plate fixedly connected to the middle of the lower end of the sliding sleeves, a fixed retaining plate fixedly connected to the lower end of the outer rod near the rear side, a sliding groove provided in the middle of the fixed retaining plate and the two sets of movable retaining plates, a sliding cylinder slidably installed through the three sets of sliding grooves, a measuring rod slidably connected inside the sliding cylinder, and a stop rod fixedly connected to the left end of the measuring rod near the rear side.

[0006] Furthermore, the upper and lower ends of the outer rod are provided with limit grooves near the left and right sides, and the limit block passes through and is slidably connected inside the limit groove. The linear movement of the moving sleeve is ensured by the cooperation of the limit groove and the limit block.

[0007] Furthermore, the front end of the bidirectional threaded rod passes through the outer rod and is fixedly mounted with a knob. The upper end of the outer rod is provided with a scale near the front side. The upper half of the front sliding sleeve is provided with a reading plate in the middle. The reading plate is in contact with the scale. The specially designed reading plate allows for more precise reading of the measured value.

[0008] Furthermore, the outer side of the slide cylinder is fixedly fitted with limit rings at both ends of the moving plate and the fixed plate. The left end of the slide cylinder is provided with a measuring groove near the rear side. The left end of the abutment passes through and is slidably connected inside the measuring groove. The measuring groove is used for the movement of the abutment during measurement and is used to measure the protruding part of the tooth surface.

[0009] Furthermore, a fixing member is fixedly connected to the front end of the moving plate on the right side of the slide groove. A spring rod is fixedly connected through the inside of the fixing member. A movable sleeve is rotatably sleeved on the outside of the slide cylinder at the corresponding spring rod. The movable sleeve is fixedly connected to the spring rod. It is worth mentioning that the design of the movable sleeve ensures that the connection between the slide cylinder and the spring rod will not change when the slide cylinder rotates, thus ensuring the rationality of the structural design.

[0010] Furthermore, the telescopic rod of the spring rod is provided with a second scale, and the front end of the measuring rod is fixedly installed with a second knob. It is worth mentioning that the initial position of the second scale on the telescopic rod of the spring rod is zero. As the telescopic rod is pushed into the interior, the scale value at its cross-section is the measured value. The structure is simple and practical.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This dental orthodontic measuring rod features a clever symmetrical design, allowing staff to directly read measurements from outside the mouth. The symmetrical arrangement of the fixed and movable clasps, along with the bidirectional threaded rod transmission mechanism, ensures both accuracy and convenience. The scale design is intuitive and clear, with values ​​increasing sequentially from front to back, making the measurement process simpler and faster, greatly improving work efficiency. Furthermore, the adjustable movable clasp can adapt to the measurement needs of teeth of different sizes, enhancing the flexibility and applicability of the measurement.

[0013] 2. In addition to measuring tooth dimensions, this measuring rod also has the function of assessing tooth misalignment. By rotating knob two, the measuring rod moves the slide and the abutment to fit against the tooth surface. Utilizing the telescopic mechanism of the measuring groove and spring rod, the degree of tooth misalignment can be accurately measured. This design not only simplifies the measurement process and reduces patient discomfort, but also provides more comprehensive and accurate dental data support. This data is crucial for developing personalized orthodontic treatment plans and helps improve treatment outcomes. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-4A dental orthodontic measuring rod includes an outer rod 1. A bidirectional threaded rod 2 is rotatably mounted inside the middle of the outer rod 1. Two sets of symmetrical movable sleeves 3 are threaded onto the bidirectional threaded rod 2 near the front and rear sides. Limiting blocks 4 are fixedly connected to the upper and lower ends of the movable sleeves 3. Sliding sleeves 5 are slidably mounted on the outer side of the outer rod 1 near the front and rear sides. The movable sleeves 3 are fixedly connected to the sliding sleeves 5 through the limiting blocks 4. Movable clamping plates 7 are fixedly connected to the middle of the lower end of each sliding sleeve 5. Fixed clamping plates 8 are fixedly connected to the lower end of the outer rod 1 near the rear side. Sliding grooves 12 are provided in the middle of the fixed clamping plates 8 and the two sets of movable clamping plates 7. A sliding cylinder 1 is slidably mounted through the three sets of sliding grooves 12. 3. A measuring rod 15 is slidably connected inside the sliding cylinder 13. A stop rod 16 is fixedly connected to the left end of the measuring rod 15 near the rear side. The fixed clamp plate 8 is placed behind the tooth to be measured. The double-threaded rod 2 is rotated by turning the knob 9. The rotation of the double-threaded rod 2 can drive the moving sleeve 3 to move. The movement of the moving sleeve 3 can drive the limiting block 4 to move the sliding sleeve 5 synchronously. Thus, the movement of the sliding sleeve 5 can drive the rear movable clamp plate 7 to be clamped in the gap between the tooth to be measured and the previous tooth. Since the front movable clamp plate 7 and the rear movable clamp plate 7 are symmetrical and move symmetrically, the size of the tooth to be measured can be obtained by observing the scale value on the scale 10 of the reading plate 11.

[0021] Please see Figures 2-3 The outer rod 1 has limit grooves 6 at both ends near the left and right sides. Limiting blocks 4 pass through and slide inside the limit grooves 6. The front end of the bidirectional threaded rod 2 passes through the outer rod 1 and is fixedly installed with a knob 9. The upper end of the outer rod 1 has a scale 10 near the front side. The upper half of the front sliding sleeve 5 has a reading plate 11 in the middle. The reading plate 11 fits against the scale 10. It is worth mentioning that the scale 10 is zero near the front end of the outer rod 1 and increases sequentially from front to back. This symmetrical design allows the operator to read the measurement value directly outside the mouth during measurement, which is more intuitive, convenient and quick. The adjustable movable clasp 7 can be used to measure teeth of different sizes. The movable clasp 7 and the fixed clasp 8 can be aligned with the gap between the teeth, making it flexible to use.

[0022] Please see Figures 2-4Limiting rings 14 are fixedly sleeved on the outer side of the slide cylinder 13 at both ends of the moving plate 7 and the fixed plate 8. A measuring groove 17 is provided on the left end of the slide cylinder 13 near the rear side. The left end of the abutment rod 16 passes through and is slidably connected inside the measuring groove 17. A fixing member 18 is fixedly connected to the front end of the moving plate 7 at the right side of the slide groove 12. A spring rod 19 passes through and is fixedly connected inside the fixing member 18. A movable sleeve 20 is rotatably sleeved on the outer side of the slide cylinder 13 at the corresponding spring rod 19. The movable sleeve 20 is fixedly connected to the spring rod 19. A scale 21 is provided on the telescopic rod of the spring rod 19. A knob 22 is fixedly installed on the front end of the measuring rod 15. By adjusting, the moving plate 7 and the fixed plate 8 are spaced one tooth apart from the front and rear ends of the tooth to be measured, and a lateral measurement is adopted. At this time, by rotating the knob 22, the measuring rod 15 drives the slide cylinder 13 to rotate synchronously. Finally, the abutment 16 is brought into contact with the tooth surface. Then, by pulling the measuring rod 15 outward, the abutment 16 slides inside the measuring groove 17. When the abutment 16 passes the middle tooth, it will be affected by its protruding part. The abutment 16 will drive the measuring rod 15 to slide the slide cylinder 13 to the other side of the slide groove 12. The slide cylinder 13 will maintain the overall consistency due to the action of the limiting ring 14. Therefore, when the slide cylinder 13 moves, it will squeeze the spring rod 19 through the movable sleeve 20, causing its telescopic rod to slide inward. By observing the change of the scale 21 on the telescopic rod of the spring rod 19, the deviation size of the tooth to be measured can be known. The operation is simple. The measurement value can be read and recorded directly outside the mouth. It is convenient and quick. Various data of the teeth can be measured, providing sufficient and accurate data support for the treatment plan of orthodontic treatment and ensuring the integrity of this technical solution.

[0023] Working principle: In use, place the fixed clasp 8 behind the tooth to be measured. Rotate the knob 9 to rotate the double-threaded rod 2. The rotation of the double-threaded rod 2 drives the moving sleeve 3 to move. The movement of the moving sleeve 3 causes the limiting block 4 to move the sliding sleeve 5 synchronously. Thus, the movement of the sliding sleeve 5 causes the rear movable clasp 7 to be engaged in the gap between the tooth to be measured and the previous tooth. Since the front movable clasp 7 and the rear movable clasp 7 are symmetrical and move symmetrically, the size of the tooth to be measured can be obtained by observing the scale value on the reading plate 11 on scale 10. Furthermore, by adjusting the movable clasp 7 and the fixed clasp 8 to be evenly spaced from the front and rear ends of the tooth to be measured... When measuring from the side, skipping one tooth, the measuring rod 15 rotates synchronously with the slide cylinder 13 by rotating knob 22, eventually bringing the abutment 16 into contact with the tooth surface. Then, by pulling the measuring rod 15 outward, the abutment 16 slides inside the measuring groove 17. When the abutment 16 passes the middle tooth, it will be affected by its protruding part, and the abutment 16 will drive the measuring rod 15 to slide the slide cylinder 13 to the other side of the groove 12. When the slide cylinder 13 moves horizontally, it will squeeze the spring rod 19 through the movable sleeve 20, causing its telescopic rod to slide inward. By observing the change of the scale 21 on the telescopic rod of the spring rod 19, the skewness of the tooth to be measured can be determined.
