The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described:

[0026] As Figures 1-3 shown, a go-no-go gauge 12 inspection tool with depth detection includes a hole diameter detection mechanism 1 for detecting the diameter of a blind hole and a hole depth detection mechanism 2. The hole depth detection mechanism 2 includes a mandrel 21 and a depth detection block 22. A sliding connection portion 23 is provided at any position outside both ends of the mandrel 21. The depth detection block 22 is slidably sleeved with the sliding connection portion 23. A low surface 22a and a high surface 22b are provided on the upper end surface of the depth detection block 22;

[0027] The hole diameter detection mechanism 1 includes a go gauge 11 and a no-go gauge 12 respectively provided at both ends of the mandrel 21. When the go gauge 11 contacts the bottom of the blind hole and the upper end surface of the sliding connection portion 23 is located between the low surface 22a and the high surface 22b, the hole depth of the blind hole (not shown in the figure) is qualified;

[0028] It further includes a limit mechanism 3, and the limit mechanism 3 is used to prevent the depth detection block 22 from detaching from the sliding connection portion 23.

[0029] In this embodiment, the go - gauge 11 and no - go - gauge 12 of the aperture detection mechanism 1 are respectively arranged at both ends of the mandrel 21, and a sliding connection part 23 slidably connected to the depth detection block 22 is arranged at a set position outside both ends of the mandrel 21. A low surface 22a and a high surface 22b are arranged on the upper end surface of the depth detection block 22. When detecting the go - no - go of the aperture of a blind hole with the no - go - gauge 12, if the go - gauge 11 is qualified, the end of the go - gauge 11 touches the bottom of the blind hole. At the same time, it is judged whether the hole depth is qualified by the upper end surface of the sliding connection part 23 staying at the position of the depth detection block 22. If the upper end surface of the sliding connection part 23 is located at any position between the low surface 22a and the high surface 22b, the hole depth of the blind hole is qualified; otherwise, it is unqualified.

[0030] With this inspection tool, the quality inspector can confirm whether the depth of the blind hole meets the standard while inspecting the diameter of the blind hole.

[0031] In this embodiment, the depth detection block 22 is a hollow cylinder, and the low surface 22a and the high surface 22b each account for half of the upper circular surface of the depth detection block 22.

[0032] Further, as Figure 1 shown, for the convenience of taking and using, it further includes a handle 4. The mandrel 21 includes a first shaft section 211 and a second shaft section 212. The go - gauge 11 and the sliding connection part 23 are respectively arranged on the first shaft section 211, and the no - go - gauge 12 is arranged on the second shaft section 212.

[0033] The first shaft section 211 and the second shaft section 212 are connected by the handle 4.

[0034] Further, inspection tool information (not shown in the figure) is engraved on the handle 4.

[0035] Further, as Figure 1 、 2 、3 shown, in order to prevent the depth detection block 22 from detaching from the sliding connection part 23 and enable the depth detection block 22 to slide relative to the sliding connection part 23 within a set small range, improving the connection stability and detection accuracy. An axially extending chute 31 is provided on the outer surface of the sliding connection part 23, a limiting hole 32 horizontally penetrating from the inside to the outside is provided on the depth detection block 22, the limiting hole 32 is correspondingly arranged with the chute 31, a limiting rod 33 is arranged in the limiting hole 32, one end of the limiting rod 33 extends into the chute 31, and the limiting hole 32, the limiting rod 33 and the chute 31 form the limiting mechanism 3.

[0036] Further, as Figure 1 、 2 shown, the length of the depth detection block 22 is not equal to the length of the sliding connection part 23.

[0037] In this embodiment, when the end of the go - gauge 11 touches the bottom of the blind hole, the upper end surface of the sliding connection part 23 can move between the lower surface 22a and the upper surface 22b through the above - mentioned structure, thereby realizing depth detection.

[0038] Furthermore, as Figure 2 shown, in order to visually, clearly, and accurately observe whether the upper end surface of the sliding connection part 23 is at the position between the lower surface 22a and the upper surface 22b; an axially extending notch 221 is provided at the connection between the lower surface 22a and the upper surface 22b on the depth detection block 22.

[0039] Furthermore, as Figure 1 shown, in order to simplify the structure and reduce the number of components; the first shaft section 211, the go - gauge 11, and the sliding connection part 23 are of an integral structure, and the second shaft section 212 and the no - go gauge 12 are of an integral structure.

[0040] Furthermore, in order to more conveniently and labor - savingly pick up, place, and use the inspection tool; an anti - slip pattern (not shown in the figure) is provided on the outer surface of the handle 4.

[0041] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model patent.
