Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building construction detection, and in particular to a Leeb hardness tester sensor auxiliary device that is easy to operate with one hand. Background Art
[0002] Leeb hardness tester can measure a variety of metal materials quickly and easily based on the Leeb hardness test principle. Its components include a high-definition display, sensor connecting wire and sensor. During testing, the sensor must be completely in contact with the surface of the object being tested to ensure data accuracy.
[0003] For example, a dual-purpose Leeb hardness tester disclosed in Chinese patent announcement number (CN207488099U) includes a host and an impact device, and also includes a socket. The host is connected to the impact device through the socket. Both the host and the impact device are provided with direct plug-in interfaces. The host and the impact device are connected for data communication through the direct plug-in interface. The Leeb hardness tester combines the advantages of both an integrated Leeb hardness tester and a split Leeb hardness tester. On the one hand, the impact device can be replaced by itself, and on the other hand, the portability of the Leeb hardness tester is ensured. The host and the impact device can also be separated for measurement.
[0004] However, as in the above patent, there is still the problem of inconvenient operation of the Leeb hardness tester sensor. In actual work, the sensor can only be operated with one hand due to the inconvenient on-site environment. Since the area of the sensor end is small, it is difficult to ensure that the sensor end is completely overlapped with the object to be tested, resulting in distortion of the test data.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0024] 1.

The anti-rotation plug 24 is fixed to the lower surface of the limiting ring 23, and the sleeve tube 22 is screwed onto the connecting screw sleeve 21 through a rotating action, thereby being fixed to the end of the hardness tester body 1. The locking nut 25 is threadedly connected to the outer side of the connecting screw sleeve 21 and is located above the limiting ring 23.
[0033] In this embodiment, a docking groove 26 is provided on the upper surface of the sleeve 22, and the distance between the inner walls on the left and right sides of the docking groove 26 is equal to the width of the anti-rotation block 24. The limiting ring 23 slides to drive the anti-rotation block 24 to move and insert into the docking groove 26 on the sleeve 22 to prevent the hardness tester from rotating during the measurement process and ensure the accuracy of the measurement. The diameter of the limiting ring 23 is equal to the diameter of the sleeve 22, and the length of the anti-rotation block 24 is equal to the depth of the inner cavity of the docking groove 26. Tightening the locking nut 25 and making it abut against the limiting ring 23 can fix the position of the limiting ring 23 to prevent it from moving during the measurement process and ensure that the anti-rotation block 24 will not detach from the docking groove 26. Through the interaction and precise cooperation of these components, the disassembly and assembly connection between the hardness tester body 1 and the expansion mechanism 3 is realized.
[0034] See also Figure 3In order to expand the hardness tester for one-handed operation, the expansion mechanism 3 in this embodiment includes an extension sleeve 31, an adjusting screw sleeve 32, a rotating screw sleeve 33, an expansion sleeve 34 and an expansion contact frame 35.

The user can adjust the position between the expansion contact frame 35 and the end of the hardness tester by rotating the rotating screw sleeve 33 on the adjusting screw sleeve 32 to meet different measurement requirements.
[0035] In this embodiment, the shape of the expanded contact frame 35 is conical, and the diameter of the expanded contact frame 35 is larger than the diameter of the hardness tester body 1, the diameter of the extended sleeve 31 is equal to the diameter of the sleeve tube 22, the length of the rotating screw 33 is larger than the length of the adjusting screw sleeve 32, and the expanded sleeve 34 and the expanded contact frame 35 provide a larger support area, making it easy to ensure that the end of the sensor is perpendicular to and completely fits the object to be detected when operated with one hand.
[0036] The working principle of the above embodiment is:
[0037] (1) When the hardness tester is connected for use, the connecting screw sleeve 21 is directly fixed to the end of the hardness tester body 1 and has an external thread for connecting with other components. The sleeve 22 is screwed onto the connecting screw sleeve 21 by a rotating action, thereby being fixed to the end of the hardness tester body 1. Then, the limit ring 23 slides to drive the anti-rotation plug 24 to move and insert into the docking groove 26 on the sleeve 22 to prevent the hardness tester from rotating during the measurement process and ensure the accuracy of the measurement. The locking nut 25 is further tightened and abutted against the limit ring 23 to fix the position of the limit ring 23 and prevent it from moving during the measurement process, ensuring that the anti-rotation plug 24 will not detach from the docking groove 26. Through the interaction and precise cooperation of these components, the assembly and disassembly connection between the hardness tester body 1 and the expansion mechanism 3 is realized.
[0038] (2) When the hardness tester is used in an expanded one-handed operation, the user can adjust the position between the expanded contact frame 35 and the end of the hardness tester by rotating the position of the rotating screw 33 on the adjusting screw sleeve 32 to adapt to different measurement requirements. The expanded sleeve 34 and the expanded contact frame 35 provide a larger support area, making it easy to ensure that the end of the sensor is perpendicular to and completely fits the object to be tested when operating with one hand.
