Description

Technical Field

[0001] This utility model relates to the field of test probe mold structure technology, and in particular to a test mold for a metal coating thickness detection probe. Background Technology

[0002] Whether the coating thickness of engineering metal materials meets the design requirements has a significant impact on the durability of metal structures, especially for corrosion-resistant materials such as steel structures.

[0003] In existing testing equipment, the probe at the testing end is exposed separately outside the testing end, see... Figure 2 Due to the small probe area and the small radius of curvature of the component, the following problems exist when measuring curved surfaces: 1. The probe cannot effectively fit with the measuring point, and the perpendicular contact between the probe and the measuring point surface cannot be guaranteed, affecting the detection effect and the accuracy of the reading; 2. Without an auxiliary fixing structure, it is impossible to guarantee that the probe will remain stationary for 2 seconds when in contact with the measuring point, which also leads to inaccurate measurement results; 3. Due to the pure single-point contact measurement method, which cannot maintain angular contact, there are large data errors when measuring multiple times; 4. The existing detection end probe only uses a simple collar at the bottom for contact protection, while the upper probe is completely exposed, posing a certain risk of damage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a test mold for a metal coating thickness detection probe in order to overcome the shortcomings of the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a test mold for a metal coating thickness detection probe, including a protective collar installed on the measuring end post of the detection equipment, and an arc-shaped rubber fixing component is provided on the protective collar;

[0006] The arc-shaped rubber fastener includes a straight section in the center, and arc-shaped sections are symmetrically arranged on the left and right sides of the straight section. A through hole is provided in the center of the straight section for placing the probe on the measuring end post. During installation, the probe protrudes or partially protrudes above the straight section.

[0007] By adopting the above technical solution, when measuring the measuring points on a curved surface, the test piece can be fixed by three points of the test mold (probe contact point, two arc-shaped contact points), making it less likely for the arc-shaped probe to loosen when testing the arc-shaped test piece, and ensuring that the probe is as perpendicular as possible to the contact point and can maintain a stable contact time of more than 2 seconds, thus making the measurement more accurate.

[0008] The design of the straight section can help the operator determine the location of the test point.

[0009] Furthermore, the arc-shaped rubber fastener described in this utility model is an elastic rubber component, and multiple components with different radii of curvature can be customized to replace it as needed.

[0010] Furthermore, the protective collar and the arc-shaped rubber fastener described in this utility model are integrally molded structures.

[0011] Furthermore, the protective collar described in this utility model is directly sleeved or threaded onto the measuring end post.

[0012] The beneficial effects of this utility model are: This utility model solves the problems existing in the prior art. By improving the existing contact protection collar and adding a simple arc-shaped rubber fixing part, it can increase the protection of the probe to a certain extent. At the same time, it can play a left and right auxiliary fixing role when measuring the measuring point on the arc surface, so that the probe and the measuring point are in as perpendicular contact as possible, and can maintain the same angle for more than 2 seconds, thereby improving the measurement accuracy and work efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1The test mold shown is for a metal coating thickness detection probe, including a protective collar 2 installed on the measuring end post 1 of the detection equipment, and an arc-shaped rubber fixing component is provided on the protective collar 2;

[0019] The arc-shaped rubber fastener includes a straight section 3 in the center, and arc-shaped sections 4 are symmetrically arranged on the left and right sides of the straight section 3. A through hole 6 is provided in the center of the straight section 3 for placing the probe 5 on the measuring end post 1. During installation, the probe 5 protrudes or partially protrudes above the straight section 3.

[0020] The arc-shaped rubber fastener is an elastic rubber component. The protective collar 2 and the arc-shaped rubber fastener are integrally molded. The protective collar 2 is directly sleeved or threaded onto the measuring end post 1.

[0021] This invention adds an arc-shaped rubber fixing component to the protective collar, which not only increases the protection of the probe to a certain extent, but also provides lateral auxiliary fixation when measuring points on arc surfaces, ensuring that the probe and the measuring point are in as perpendicular contact as possible and maintaining the same angle for more than 2 seconds, thereby improving the measurement accuracy and work efficiency.

[0022] In practical work, multiple curved rubber fasteners with different radii of curvature can be customized and prepared in advance as needed for easy replacement to correspond to different curved surface measurement points. For example, three types of curved rubber fasteners with radii of curvature of less than 50mm, 50mm to 100mm, and greater than 100mm can be prepared for replacement, which is very convenient.
