[0003] Thread gauges are mostly used on machining production lines. They need to be used by pinching a hexahedral straight rod. Operators repeat the above actions for a long time, which not only easily causes fatigue damage to the hands, but also greatly affects work efficiency. At the same time, when using thread gauges, there are cases where the thread gauges are not in a vertical state to contact the inspection parts during operation, and the thread gauges need to be withdrawn and re-measured. Especially for new employees who have just come into contact with thread gauges, the above situation occurs more frequently, seriously affecting work efficiency;

[0004] In view of this, there is an urgent need for a thread stop gauge that can solve the above problems and improve work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0025] Please refer to the attached Figure 1-3 , a threaded plug gauge, comprising:

[0026] A threaded through-and-no-go plug gauge body 1 comprises a hexahedral straight rod 10 and a through gauge 11 and a no-go gauge 12 fixedly connected to both ends of the hexahedral straight rod 10, and end faces of the through gauge 11 and the no-go gauge 12 are provided with external connection holes 13 for improving work efficiency, and the threaded through-and-no-go plug gauge body 1 is provided with an auxiliary rotating assembly 2 matching therewith.

[0027] Specifically, the external connection hole 13 is an inner tetragonal / hexagonal hole or a cross-shaped hole;

[0028] After setting inner square / hexagonal holes or cross holes on the end faces of the go gauge 11 and the stop gauge 12, the thread gauge can be assisted by an external auxiliary rotating component 2 or other tools. For example, an electric tool with a torque function can be used to insert the external connecting hole 13, and then the go and stop gauges can be screwed in by the electric tool.

[0029] Specifically, the auxiliary rotating assembly 2 includes a sleeve 20, a rotating handle 21 and a connecting column 22. The sleeve 20 has no bottom wall. The rotating handle 21 is located on the outside of the sleeve 20 and is fixedly connected to the top wall of the sleeve 20. The connecting column 22 is located on the inside of the sleeve 20 and is fixedly connected to the middle position of the top wall of the sleeve 20. The connecting column 22 matches the external connecting hole 13.

[0030] Taking into account the problem that the power tool has a high rotation speed and cannot be stopped in time, the power tool and the thread gauge may accidentally fall off, which may cause mechanical damage to the operator. Therefore, an auxiliary rotating assembly 2 composed of a sleeve 20, a turning handle 21 and a connecting column 22 is used to assist in screwing the thread gauge. When the connecting column 22 is inserted into the external connecting hole 13, the sleeve 20 can wrap the upper end of the hexahedral straight rod 10. In this case, when the thread gauge is rotated by the turning handle 21, the auxiliary rotating assembly 2 will not be detached from the thread gauge, and the use of the turning handle 21 can also reduce the possibility of fatigue damage to the operator's hands. It is worth noting that the structure of the turning handle 21 can also be replaced by a low-speed motor to further improve the overall work efficiency. Embodiment 2

[0031] Please refer to the attached Figure 4-5

[0032] Specifically, the auxiliary rotating assembly 2 includes a sleeve 20, a handle 21 and at least one group of locking assemblies 3. The sleeve 20 has no bottom wall. The handle 21 is located on the outside of the sleeve 20 and is fixedly connected to the top wall of the sleeve 20. The locking assembly 3 includes a convex column 30, an arc-shaped pressure plate 31, a spring 32 and a rotating shaft 33. One end of the spring 32 is fixedly connected to the outside of the curved side wall of the sleeve 20, and the other end is fixedly connected to the concave side wall of the arc-shaped pressure plate 31 close to one end of the top wall of the sleeve 20. The rotating shaft 33 is hinged at the middle position of the concave side wall of the arc-shaped pressure plate 31, and is fixedly connected to the sleeve 20. One end of the convex column 30 passes through the side wall of the sleeve 20 and is slidably connected to it, and the other end is movably connected to the arc-shaped pressure plate 31.

[0033] Specifically, a position locking hole 100 matching the boss 30 is provided on the side wall of the hexahedral straight rod 10 .

[0034] Considering that the auxiliary rotating assembly 2 and the hexahedral straight rod 10 are connected by simply relying on the external connecting hole 13 and the connecting column 22, each time the detection part is replaced, it is necessary to move the threaded plug gauge body 1 and the auxiliary rotating assembly 2 to the new detection part and then assemble them. In order to improve work efficiency, a locking assembly 3 is provided on the original auxiliary rotating assembly 2. When the sleeve 20 is inserted into the hexahedral straight rod 10, the side of the protruding column 30 and the arc-shaped pressure plate 31 that are movably connected to the protruding column 30 moves in a direction away from the hexahedral straight rod 10. At this time, the rotating shaft 3 3, one end of the arc pressure plate 31 fixedly connected to the spring 32 will move toward the side close to the hexahedral straight rod 10, and the spring 32 will be compressed in the process. As the sleeve 20 is continuously inserted, the boss 30 moves to the position of the position locking hole 100. Under the reverse force of the spring 32, the boss 30 is snapped into the position locking hole 100, and the arc pressure plate 31 also returns to its original position. When the detection parts need to be replaced during subsequent use, the threaded plug gauge body 1 and the auxiliary rotating component 2 can be lifted up by holding the rotating handle 21. Embodiment 3

[0035] Please see attached Figure 6-7

[0036] Specifically, the threaded through-and-stop plug gauge body 1 is provided with a position correction component 4 matched therewith, and the position correction component 4 includes a positioning ring 40, a connecting ring 41, at least two groups of correction rods 42 and at least two groups of connecting plates 43, at least two groups of connecting plates 43 are respectively fixedly connected to the connecting ring 41 and the positioning ring 40 at both ends, an arc-shaped slide groove 410 is provided on the inner wall of the connecting ring 41, and a vertical slide groove 102 matching the correction rod 42 is provided on the side wall of the hexahedral straight rod 10, and the two ends of the correction rod 42 are respectively slidably connected in the arc-shaped slide groove 410 and the vertical slide groove 102;

[0037] Considering that in actual application, due to the misalignment between the thread gauge and the threaded hole of the part to be inspected, it is often necessary to withdraw the thread gauge and screw it in again for inspection, especially for new employees who are not proficient in using the thread gauge, which seriously affects the overall inspection efficiency. Therefore, a position correction component 4 is used for auxiliary inspection. When the two ends of the correction rod 42 are respectively inserted into the arc-shaped slide groove 410 and the vertical slide groove 102, when the positioning ring 40 contacts the surface of the part to be inspected, the two ends of the connecting plate 43 are respectively fixedly connected to the positioning ring 40 and the connecting ring 41, and the position of the connecting ring 41 is aligned with the part to be inspected. The threaded hole is actually in a relatively parallel state. Due to the existence of the correction rod 42, the threaded go / no-go plug gauge body 1 is in a vertical state relative to the threaded hole. At this time, when the threaded go / no-go plug gauge body 1 is moved downward, the correction rod 42 slides along the vertical slide groove 102 until the go gauge 11 / no-go gauge 12 contacts the threaded hole. At this time, the threaded go / no-go plug gauge body 1 is rotated, the positioning ring 40 remains in position, and the correction rod 42 slides along the arc-shaped slide groove 410. The above method can ensure that the threaded go / no-go plug gauge body 1 will not tilt when it is screwed into the threaded hole, thereby avoiding detection failure.

[0038] Specifically, the correction rod 42 is a sleeve rod structure, on which an adjustment handle for adjusting the length is provided; considering the possible difficulty in installing the position correction component 4, the correction rod 42 can be in the form of a sleeve rod, thereby achieving the purpose of rapid installation of the position correction component 4.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
