Technical Field
[0001] This utility model relates to the field of measurement technology, and in particular to a medical measuring ruler. Background Technology
[0002] Micrometers are typically used to precisely measure very small dimensions, with an accuracy of one-thousandth of a millimeter. While they are widely used in most industrial measurements, they can also be used as precision measuring tools in some medical fields, especially in dentistry. They provide very fine measurement accuracy and are suitable for applications requiring high precision. Micrometers can be used to measure the size and thickness of dental prosthetic instruments such as crowns, bridges, and braces. In dental implant surgery, micrometers can be used to measure the diameter and length of implants, or to measure their fit with the jawbone. The measuring jaws of medical micrometers are prone to wear after prolonged use. This is because the measuring jaws are usually made of metal, and long-term friction with the object being measured leads to wear. Wear affects measurement accuracy because once the jaw surface deforms or is damaged, the contact surface cannot be guaranteed to be completely flat and stable. This instability may increase the error of the measurement value, especially in medical equipment that requires high precision, and may even lead to diagnostic errors. This problem is particularly serious because the measuring jaws are not replaceable. On the one hand, the lifespan of the measuring tool is shortened with the accumulation of wear; on the other hand, once the measuring jaws are damaged, the performance of the entire instrument will be affected, and it may be necessary to replace the entire tool rather than just the damaged part, resulting in unnecessary costs and waste. This is a problem that urgently needs to be solved. Utility Model Content
[0003] To overcome the shortcomings of the existing technology, this utility model provides a medical measuring ruler. The device enables the measuring claw to be detached and replaced through the installation component. When the measuring claw is worn, deformed or damaged due to long-term friction, the operator can easily remove and replace the measuring claw by pulling the pull ring and moving the installation rod.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a medical measuring ruler, including a measuring ruler body, a rotating measuring head rotatably connected to the measuring ruler body, a scale line provided at the connection position between the measuring ruler body and the rotating measuring head, a clamping head connected to the inner end of the rotating measuring head, a measuring claw connected to one end of the measuring ruler body symmetrical to the clamping head, an installation component also provided on the measuring ruler body, the measuring claw being inserted into the measuring ruler body through the installation component, and a limit component provided on the installation component.
[0005] As a preferred technical solution of this utility model, the mounting assembly includes a mounting plate mounted on the outer wall of the measuring ruler body, a groove formed on the inner wall of the mounting plate, a slider slidably connected in the groove, a mounting rod connected to the slider, a return spring wound around the outer wall of the mounting rod, a pull ring fixed on the top of the mounting rod, a first insertion groove formed in the measuring ruler body, a second insertion groove formed in the measuring ruler body and communicating with the first insertion groove, and a third insertion groove formed in the measuring claw.
[0006] In a preferred embodiment of this utility model, one end of the mounting rod is connected to the inner wall of the mounting plate, and the other end of the mounting rod is connected to the outer wall of the slider.
[0007] As a preferred embodiment of this utility model, the pull ring is shaped like a circular ring, and the outer wall of the pull ring is provided with anti-slip texture.
[0008] As a preferred embodiment of this utility model, the diameter of the mounting rod is set to be equal to the inner diameter of the first insertion groove, and the inner diameter of the first insertion groove is set to be equal to the inner diameter of the third insertion groove.
[0009] As a preferred technical solution of this utility model, the limiting component includes an auxiliary plate fixedly installed on the outer wall of the mounting plate, a movable cavity opened on the inner wall of the auxiliary plate, a limiting rod slidably connected in the movable cavity, and a limiting groove opened in the mounting rod.
[0010] As a preferred embodiment of this utility model, the outer end wall of the limiting rod is provided with anti-slip texture, and the outer diameter of the inner end of the limiting rod is set to be equal to the inner diameter of the limiting groove.
[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: This device allows for the detachable and replaceable measuring claws through the installation components. When the measuring claws become worn, deformed, or damaged due to long-term friction, operators can easily remove and replace them with new measuring claws by pulling the pull ring and moving the mounting rod. Furthermore, the diameter of the mounting rod is equal to the inner diameter of the first insertion slot, and the diameter of the first insertion slot is equal to the diameter of the third insertion slot. This ensures that the new measuring claws are tightly connected to the main body of the measuring scale after installation, and that the contact surface is flat and stable. This effectively avoids increased measurement errors caused by claw surface problems, meets the high precision requirements of medical equipment, and reduces the risk of diagnostic errors.
[0012] The device allows for the individual replacement of worn measuring jaws, eliminating the need to discard the entire measuring scale due to jaw damage. Operators only need to replace the damaged measuring jaws, while the measuring scale body, rotating measuring head, clamping head, and other undamaged parts can continue to be used. This avoids the impact of wear accumulation on the overall tool life and significantly extends the overall service life of the medical measuring scale.
[0013] This device only requires the replacement of a single damaged component, eliminating the need to replace the entire measuring scale. On the one hand, it reduces the high costs associated with replacing the entire instrument; on the other hand, it avoids the waste of undamaged components such as the measuring scale body, meeting the requirements for efficient resource utilization. In addition, the limiting component can limit the installation rod by using a limiting rod when replacing the measuring claw, allowing staff to free their hands to complete the installation operation, improving replacement efficiency, further alleviating the cost and waste caused by replacing the entire tool, and effectively solving the current pain point that urgently needs to be addressed.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0017] Example: like Figure 1-5As shown, a medical measuring ruler includes a measuring ruler body 1, a rotating measuring head 2 rotatably connected to the measuring ruler body 1, a scale line 3 provided at the connection position between the measuring ruler body 1 and the rotating measuring head 2, a clamping head 4 connected to the inner end of the rotating measuring head 2, a measuring claw 5 connected to one end of the measuring ruler body 1 symmetrical to the clamping head 4, and an installation component 6 provided on the measuring ruler body 1. The measuring claw 5 is inserted into the measuring ruler body 1 through the installation component 6, and a limit component 7 is provided on the installation component 6. Mounting assembly 6 includes a mounting plate 61 mounted on the outer wall of the measuring scale body 1, a groove 62 formed on the inner wall of the mounting plate 61, a slider 63 slidably connected in the groove 62, a mounting rod 64 connected to the slider 63, a return spring 65 wound around the outer wall of the mounting rod 64, a pull ring 66 fixed on the top of the mounting rod 64, a first insertion groove 67 formed in the measuring scale body 1, a second insertion groove 68 formed in the measuring scale body 1 and communicating with the first insertion groove 67, and a third insertion groove 69 formed in the measuring claw 5; When the operator needs to disassemble the measuring claw 5, simply pull the pull ring 66 upwards, causing the pull ring 66 to move the mounting rod 64 upwards. The mounting rod 64 slides outwards in the slide groove 62 via the slider 63. During the sliding process, the return spring 65 is compressed and deformed until the mounting rod 64 moves out of the third insertion groove 69 and into the first insertion groove 67. This releases the position limit on the measuring claw 5, allowing the measuring claw 5 to be pulled outwards and removed from the second insertion groove 68, thus completing the disassembly and replacement.
[0018] It is worth noting that one end of the mounting rod 64 is connected to the inner wall of the mounting plate 61, and the other end of the mounting rod 64 is connected to the outer wall of the slider 63. The slider 63 provides guidance for the mounting rod 64 by sliding in the groove 62, ensuring that the mounting rod 64 moves stably, avoiding deviation, and ensuring that it can be accurately inserted into or removed from the insertion groove. The pull ring 66 is designed in a circular shape, and the outer wall of the pull ring 66 is provided with anti-slip texture. The circular shape makes it easy for staff to pull with their fingers, which is in line with operating habits. The anti-slip texture increases friction and prevents the hand from slipping when pulling, ensuring the reliability of operation, especially suitable for the possible wet hands in the medical environment. The diameter of the mounting rod 64 is set to be equal to the inner diameter of the first insertion slot 67, and the inner diameter of the first insertion slot 67 is set to be equal to the inner diameter of the third insertion slot 69. This ensures that the mounting rod 64 fits tightly with the two slots, which not only ensures the firmness of the limiting of the measuring claw 5, but also allows the mounting rod 64 to slide smoothly, avoiding jamming or displacement due to excessive gaps, and ensuring smooth disassembly and installation.
[0019] The limiting component 7 includes an auxiliary plate 71 fixedly installed on the outer wall of the mounting plate 61, a movable cavity 72 opened on the inner wall of the auxiliary plate 71, a limiting rod 73 slidably connected in the movable cavity 72, and a limiting groove 74 opened in the mounting rod 64; When the worker pulls the pull ring 66 upwards, the pull ring 66 moves the mounting rod 64 upwards to its highest position. At this time, the limiting groove 74 inside the mounting rod 64 is exposed, and the limiting groove 74 and the limiting rod 73 are at the same horizontal height. Then, the worker pushes the limiting rod 73, causing the limiting rod 73 to slide from the movable cavity 72 into the limiting groove 74. Finally, the limiting rod 73 limits the limiting groove 74, further limiting the position of the mounting rod 64. At this time, the worker can free up his hand to install the measuring claw 5. The outer end wall of the limiting rod 73 is provided with anti-slip texture. The outer diameter of the inner end of the limiting rod 73 is set to be equal to the inner diameter of the limiting groove 74. The anti-slip texture on the outer end increases the friction when pushing and prevents the hand from slipping. The inner end matches the diameter of the limiting groove 74 to ensure that the limiting rod 73 is tightly embedded in the limiting groove 74, and firmly limits the installation rod 64. This prevents the installation rod 64 from moving accidentally when the operator installs the measuring claw 5, and improves the safety and convenience of operation.
[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
