[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown;

[0027] A portable multi-purpose hole and shaft inspection gauge comprises a ring gauge 1.

[0028] In this embodiment: CN208520292U discloses a spray can top cover inspection gauge. Although the design can quickly detect parameters such as the top cover curvature and the can mouth diameter, thereby improving the inspection efficiency of the spray can top cover, the device is large in size and inconvenient to carry, and the quick-release head cannot be replaced according to the size of the measured object, which affects the operation. On this basis, a quick-release component 2 and a dustproof component 3 are added.

[0029] More specifically:

[0030] like Figures 1 to 4 As shown:

[0031] In combination with the above content: it also includes a quick release assembly 2 arranged behind the ring gauge 1;

[0032] The quick-release assembly 2 includes a slider 23, a threaded rod 24, a cylindrical base 27, a plug gauge 28 and a threaded rod 212. A threaded groove is provided inside the ring gauge 1, and the threaded rod 24 is threadedly connected to the ring gauge 1 through the threaded groove. The threaded rod 24 is fixedly connected to one end of the slider 23, and the other end of the slider 23 is fixedly connected to the threaded rod 212. A threaded groove is provided inside the cylindrical base 27, and the cylindrical base 27 is threadedly connected to the other end of the slider 23 through the threaded groove, and the plug gauge 28 is fixedly connected to the cylindrical base 27.

[0033] In this embodiment: because the bar 25 is fixedly connected to the slider 23, the slider 23 is fixedly connected to the threaded rod 24, and the threaded rod 24 is fixedly connected to the ring gauge 1, the ring gauge 1 slides forward to complete the detection process. When the object to be detected chooses to use the plug gauge 28, the handle 26 is pushed in the reverse direction. Because the threaded rod 212 is fixedly connected to the slider 23, the cylindrical base 27 is threadedly connected to the threaded rod 212, and the plug gauge 28 is fixedly connected to the cylindrical base 27, the plug gauge 28 moves synchronously to complete the detection process.

[0034] It should be noted that both the ring gauge 1 and the plug gauge 28 can be replaced according to the size of the object to be tested.

[0035] Going further:

[0036] In an optional embodiment, the quick-release assembly 2 also includes a protective cover 21, a rod 25 and a handle 26. The inner side of the central position of the protective cover 21 is slidably connected to the outer surface of the slider 23. A T-shaped slot 22 is provided on the outer surface of the protective cover 21. One end of the rod 25 is fixedly connected to the slider 23, and the other end of the rod 25 passes through the T-shaped slot 22 and is fixedly connected to the handle 26.

[0037] In this embodiment, the dust cover 31 is threadedly connected to the protective cover 21, so the dust cover 31 rotates synchronously and leaves the protective cover 21, and a forward force is applied to the handle 26 at this time. Since the handle 26 is fixedly connected to the bar 25, the bar 25 moves forward synchronously.

[0038] Going further:

[0039] In an optional embodiment, the quick-release assembly 2 further includes a slider groove 29, a spring 210 and a slider 211. The outer surface of the protective cover 21 is provided with a slider groove 29, one end of the spring 210 is fixedly connected to the inner wall of the slider groove 29, and the other end of the slider groove 29 is fixedly connected to the slider 211.

[0040] In this embodiment, the bar 25 moves to exert a force on the second slider 211 , so that the second slider 211 moves inside the slider slot 29 and compresses the spring 210 .

[0041] Going further:

[0042] In an optional embodiment, it further includes a dustproof component 3 arranged behind the ring gauge 1;

[0043] The dustproof assembly 3 includes a dustproof cover 31 . A threaded groove is formed inside the dustproof cover 31 . The dustproof cover 31 is threadedly connected to the protective cover 21 via the threaded groove.

[0044] In this embodiment, the dust cover 31 is threadedly connected to the protective cover 21 , so the dust cover 31 rotates synchronously and leaves the protective cover 21 .

[0045] Going further:

[0046] In an optional embodiment, the dustproof component 3 further includes anti-slip strips 32 , and a plurality of anti-slip strips 32 are fixedly connected to the outer surface of the dustproof cover 31 .

[0047] In this embodiment, when the object to be detected chooses to use the ring gauge 1, the anti-slip strip 32 is rotated. Since the anti-slip strip 32 is fixedly connected to the dust cover 31, and the dust cover 31 is threadedly connected to the protective cover 21, the dust cover 31 rotates synchronously and leaves the protective cover 21.

[0048] Working principle: When the object to be detected chooses to use the ring gauge 1, the anti-slip strip 32 is rotated. Since the anti-slip strip 32 is fixedly connected to the dust cover 31, and the dust cover 31 is threadedly connected to the protective cover 21, the dust cover 31 rotates synchronously and leaves the protective cover 21. At this time, a forward force is applied to the handle 26. Since the handle 26 is fixedly connected to the bar 25, the bar 25 moves forward synchronously. The movement of the bar 25 applies a force to the slider 211, so that the slider 211 moves inside the slider groove 29 and compresses the spring 210. Since the bar 25 is fixedly connected to the slider 1 23, the slider 1 23 rotates inside the protective cover 21. At this time, the handle 26 is pushed to make the bar 25 slide inside the T-slot 22. Since the bar 25 is fixedly connected to the slider 1 23, the slider One 23 is fixedly connected to the threaded rod one 24, and the threaded rod one 24 is fixedly connected to the ring gauge 1, so the ring gauge 1 slides forward, thereby completing the detection process. When the object to be detected chooses to use the plug gauge 28, the handle 26 is pushed in the reverse direction. Because the threaded rod two 212 is fixedly connected to the slider one 23, the cylindrical base 27 is threadedly connected to the threaded rod two 212, and the plug gauge 28 is fixedly connected to the cylindrical base 27, the plug gauge 28 moves synchronously, thereby completing the detection process. When the detection is completed and it needs to be carried, the handle 26 is pushed successively at this time. Because the spring 210 is fixedly connected to the slider two 211, the slider one 23 is suppressed under the action of the elastic potential energy of the spring 210, so that the slider one 23 will not swing back and forth inside the protective cover 21, which is convenient for the staff to operate.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
