[0003] Comparing the threaded products of my country with those of foreign industrialized countries, the biggest problem of my country's threaded products is the processing quality. The premise of improving the thread processing quality is to ensure that the processing errors of various thread parameters are controlled within the specified tolerance of the product. This requires not only advanced processing technology, but also various thread single parameter measuring instruments.

[0004] There are many thread inspection templates at present, and the inspection of thread size parameters, whether the thread tooth profile meets the specifications, etc. requires the use of separate inspection templates, which leads to a long thread inspection time and cumbersome operation, reducing the work efficiency of the inspectors. Utility Model Content

[0005] The purpose of the utility model is to provide a thread detection template to solve the problem raised in the above background technology that currently the detection of thread size parameters, whether the thread tooth profile conforms to the specifications, etc. all require the use of a separate detector, resulting in a long thread detection time and cumbersome operation, resulting in low work efficiency of the inspectors.

[0009] A first detection sample, rotatably connected in the first cavity;

[0010] A second detection sample, rotatably connected in the second cavity;

[0011] Among them, one side of the first test sample and the second test sample are both threaded, and the thread tooth shape of the second test sample corresponds to the thread tooth shape of the first test sample, and a qualified line is marked on the second test sample.

[0012] Preferably, the first detection template and the second detection template may be provided in plurality, and the thread tooth profiles of the plurality of second detection templates correspond one-to-one to the thread tooth profile of the first detection template.

[0013] Preferably, the first test template is marked with corresponding thread size parameters.

[0014] Preferably, the first cavity and the second cavity are located on the same side of the detection end, and a rotating shaft passes through the top, and the first detection sample and the second detection sample are both installed on the axis of the rotating shaft.

[0015] Preferably, the threaded sides of the first detection sample plate and the second detection sample plate face toward the inside of the first cavity and the second cavity respectively.

[0016] Preferably, first grooves are provided on the sides of the first cavity and the second cavity.

[0017] Preferably, the non-threaded sides of the first detection sample and the second detection sample are both provided with strip-shaped through holes along their length directions.

[0018] Preferably, a second groove is provided on a side of the handheld end away from the first cavity and the second cavity, and anti-slip grooves are provided in the second groove.

[0034] A first detection sample 4, rotatably connected in the first cavity 2;

[0035] A second detection sample 5, rotatably connected in the second cavity 3;

[0036] One side of the first test sample 4 and the second test sample 5 are both threaded, and the thread profile of the second test sample 5 corresponds to the thread profile of the first test sample 4 , and a qualified line 51 is marked on the second test sample 5 .

[0037] It should be noted that the qualified line 51 is marked according to the specified tolerance range. When the horizontal line where the thread crest is located is higher than the qualified line 51, it is judged that the thread to be tested is not within the specified tolerance range, that is, the thread is unqualified; when the horizontal line where the thread crest is located is not higher than the qualified line 51, it is judged that the thread to be tested is within the specified tolerance range, that is, the thread is qualified.

[0038] When in use, first select a suitable first test template 4 according to the thread profile to test the thread to be tested. If the first test template 4 is completely consistent with the thread to be tested, it means that the thread to be tested is qualified, and the corresponding thread size data on the first test template 4 is the size parameter of the thread to be tested; if the first test template 4 is not consistent with the thread to be tested, then select a suitable second test template 5 according to the thread profile, and judge whether the thread to be tested is within the specified tolerance through the qualified line 51 on the second test template 5. If it is within the specified tolerance, the corresponding thread size data on the first test template 4 is the size parameter of the thread to be tested. If it is not within the specified tolerance, the thread to be tested is judged to be unqualified.

[0039] The first detection template 4 and the second detection template 5 are both rotatably connected to the detection end 11, so that the detection personnel can adjust the appropriate angle according to the actual situation, which is convenient for the detection personnel to use, and can be stored in the cavity when not in use to prevent loss; through the coordinated use of the first detection template 4 and the second detection template 5, the size parameters of the thread to be tested can be obtained while detecting whether the thread to be tested is qualified, which shortens the time of thread detection, simplifies the operation, and thus improves the work efficiency of the detection personnel.

[0040] Specifically, the first detection template 4 and the second detection template 5 may be provided in plurality, and the thread profiles of the plurality of second detection templates 5 correspond one-to-one to the thread profile of the first detection template 4 .

[0041] For the convenience of reading, the first detection template 4 is marked with corresponding thread size parameters. Specifically, the thread size parameters include pitch, thread depth and thread angle.

[0042] It should be noted that, when there are multiple first detection templates 4, the thread size parameters on the multiple first detection templates 4 are all different.

[0043] Furthermore, the first cavity 2 and the second cavity 3 are located on the same side of the detection end 11, and a rotating shaft 6 passes through the top, and the first detection sample 4 and the second detection sample 5 are both installed on the axis of the rotating shaft 6, so that the first detection sample 4 and the second detection sample 5 can be rotated according to actual needs to adjust to a suitable angle.

[0044] In order to prevent the threads from scratching the inspectors, the threaded sides of the first inspection template 4 and the second inspection template 5 are respectively facing the inside of the first cavity 2 and the second cavity 3.

[0045] In order to facilitate the turning out of the sample, first grooves 7 are provided on the sides of the first cavity 2 and the second cavity 3 .

[0046] Specifically, the non-threaded sides of the first detection sample 4 and the second detection sample 5 are both provided with strip-shaped through holes 8 along their length directions. When in use, the inspector can hook the corresponding strip-shaped through hole 8 on the required sample to pull it out.

[0047] Furthermore, a second groove 9 is provided on a side of the handheld end 12 away from the first cavity 2 and the second cavity 3, and an anti-slip pattern is provided in the second groove 9 to prevent inaccurate detection caused by hand sliding.

[0048] It should be noted that during testing, the working part of the thread should be measured as much as possible to make the test results more accurate.
