[0002] Dosimeter placement is a key pre-work in dose field testing, and its accuracy directly affects the reliability of test data and the validity of experimental results. At present, dosimeter placement mainly relies on manual operation by operators.

However, the manual placement method lacks standardized auxiliary tools and it is difficult to ensure the position accuracy of the dosimeter within the range of micrometers or millimeters. Even if the operator tries his best to place the dosimeter at the specified position, position deviation may still occur due to measurement errors or manual operation deviations. This low-precision problem is particularly obvious in high-requirement dose field tests. Summary of the Invention

[0049] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] Please refer to the attached Figure 1, an embodiment of the present invention provides a dosimeter placement caliper, which includes a substrate 1, positioning grooves 2, scale marks 3, and a holding area 4. The substrate 1 is a rectangular flat plate structure, providing a bearing surface for dosimeter placement;

[0051] The positioning grooves 2 are evenly distributed on the surface of the substrate 1. Designed according to the coordinate system of dose field testing, the positioning grooves 2 are rectangular grooves, and their sizes are adapted to the fixed points of the dosimeter, used to define the placement positions of the dosimeter;

[0052] The scale marks 3 are arranged along the middle of the substrate 1, made by laser etching or printing technology, providing an auxiliary reference for the placement position;

[0053] The holding area 4 is located at one end of the substrate 1, designed as a convex or frame structure, facilitating the operator to hold and move the caliper.

[0054] Specifically, the dosimeter placement caliper, through the precisely designed positioning grooves 2 and laser-etched scale marks 3, effectively improves the placement accuracy and efficiency, while significantly reducing human errors. The processing accuracy of the positioning grooves reaches ±0.05 mm, ensuring that the position of the dosimeter fully meets the design requirements; the scale marks use millimeters or centimeters as units, and the position error is less than ±0.1 mm, meeting the needs of high-precision dose field testing. Users only need to embed the dosimeter into the positioning groove, without repeated measurement and adjustment. The placement process is convenient and fast, greatly improving the work efficiency. In addition, the standardized design of the caliper avoids placement deviations caused by different operating methods of the operator, ensuring the consistency and reliability of the measurement results from the source. The wear-resistant coating on the surface of the scale marks further extends the service life of the product. Even in high-frequency use and complex environments, the caliper can maintain its clarity and measurement accuracy, providing a solid guarantee for long-term stable dose field testing.

[0055] The substrate 1 is made of aluminum alloy or engineering plastic, with a thickness of 3 to 10 mm.

[0056] Specifically, aluminum alloy has excellent mechanical properties, including high strength and corrosion resistance, which can ensure the stability and durability of the caliper during long-term use. At the same time, the density of aluminum alloy is relatively low, ensuring that the substrate is lightweight while meeting the strength requirements.

[0057] Engineering plastic has excellent insulation, wear resistance, and impact resistance, and is suitable for use in scenarios sensitive to electromagnetic interference such as medical and nuclear industries. In addition, engineering plastic has good processability and can be quickly formed by injection molding or CNC machining, reducing the manufacturing cost.

[0058] The thickness range of 3 to 10 mm is to reduce the weight of the material used while ensuring the strength of the substrate. If the thickness is too thin, the substrate may deform and affect the positioning accuracy, while if the thickness is too large, it will increase the weight of the caliper and reduce its portability.

[0059] The selection of aluminum alloy or engineering plastic materials for the substrate ensures that the caliper not only has excellent structural strength but also has a low weight, making it convenient to carry and use.

[0060] The optimized design of the thickness range improves the balance between the strength and portability of the product, making it suitable for a variety of test environments.

[0061] The scale markings 3 use millimeters or centimeters as the unit, with a line width of 0.1 to 0.3 millimeters, and a wear-resistant coating is added on the surface.

[0062] Specifically, for the selection of scale units: The design of scale markings in millimeters or centimeters can meet the requirements for high-precision placement in dose field tests. For example, millimeters can be used for small-dose field tests, while centimeters are suitable for large-scale dose field placement.

[0063] Line width range: The line width of 0.1 to 0.3 millimeters is to ensure that the scale markings are visible to the naked eye while maintaining clarity. If it is too thin, the scale may be difficult to observe, and if it is too wide, the accuracy of the scale marking position will be reduced.

[0064] Wear-resistant coating treatment: Adding a wear-resistant coating, such as polyurethane, fluorocarbon coating or titanium nitride coating, on the surface of the scale markings can improve the scratch resistance of the scale, extend the service life, and ensure that the scale markings are still clearly visible after long-term operation. The coating thickness should be appropriate so as not to affect the clarity of the scale markings.

[0065] The combination of clear scale markings and wear-resistant coating ensures that the caliper can maintain high-precision measurement ability during long-term use.

[0066] The scale marking design meets the accuracy requirements of different dose fields, and at the same time, the wear-resistant treatment improves the reliability and durability of the product.

[0067] The gripping area 4 is of a frame structure, integrally connected to the substrate 1, with a size greater than 5 cm and less than 10 cm.

[0068] Specifically, for the frame structure: The gripping area adopts a frame design, providing a balance between portability and rigidity. The inside of the frame is empty, reducing unnecessary material use while ensuring the rigidity and stability of the hand gripping area.

[0069] Size range: The internal size of the gripping area is designed to be greater than 5 cm and less than 10 cm, meeting the needs of different operators' palm sizes. The design of greater than 5 cm is suitable for users with smaller palms, and the limit of not exceeding 10 cm ensures that the overall gripping area will not be too large to affect the operation convenience.

[0070] Integral connection: The holding area and the substrate 1 are integrally connected by integral molding or welding technology, avoiding loosening or damage that may occur to independent parts, and improving the structural integrity and durability.

[0071] The frame design reduces the overall weight while maintaining the strength and stability of the holding area.

[0072] The internal size range is optimized to fit the hand sizes of different users, improving the operating comfort and ease of use.

[0073] The surface of the holding area 4 is provided with anti-slip textures or anti-slip rubber coatings. The anti-slip textures adopt a criss-cross grid design, and the coating thickness is 0.5 to 1 millimeter.

[0074] Specifically, for the anti-slip textures: The criss-cross grid texture design can provide sufficient friction in different holding directions, ensuring that the operator's hand does not slip even when sweating during use.

[0075] For the anti-slip coating: A rubber coating with a thickness of 0.5 to 1 millimeter is used, which can further enhance the anti-slip performance and at the same time improve the holding comfort. The rubber material has a certain elasticity, which can relieve the hand fatigue caused by long-term operation.

[0076] The anti-slip design significantly improves the stability of the caliper during operation, and is especially suitable for test scenarios in high humidity or complex environments.

[0077] The elasticity of the anti-slip coating relieves the hand fatigue during long-term use and improves the user experience.

[0078] The edge of the holding area 4 adopts an arc transition design to avoid hand discomfort caused by long-term use.

[0079] Specifically, for the arc transition treatment: The edge of the holding area adopts an arc design with a curvature radius of 1 to 3 millimeters, avoiding possible compression or scratching of the hand skin by sharp corners or straight edges.

[0080] Processing method: The arc transition is achieved by CNC machining, grinding or mold forming, etc., ensuring that the edge is smooth and free of burrs.

[0081] The arc transition design eliminates the pressure point distribution of sharp corners on the hand, improving the comfort during long-term use.

[0082] By optimizing the edge shape, the possibility of accidental damage caused by machining is reduced, improving the safety and user-friendly design of the product.
