Description

Technical Field

[0001] The utility model relates to the technical field of thread gauges, in particular to a novel thread gauge. Background Art

[0002] A thread gauge is a tool used to measure thread specifications and dimensions, and it plays an important role in the field of industrial manufacturing. The thread gauge includes a through end and a stop end. The through end is the lower limit of the allowable deviation of the aperture. If it cannot pass, it means that the aperture of the product is too small. The stop end is the upper limit of the allowable deviation of the aperture. If it can pass, it means that the aperture is too large.

[0003] The structure of the existing thread gauge is mostly as disclosed in the Chinese patent with publication number CN217818426U, which is named a through-stop gauge structure for easy replacement of thread gauge head. A through-end thread gauge head and a stop-end thread gauge head are respectively provided at both ends of the gauge body for easy replacement of thread gauge head, and the length of the through-end thread gauge head and the stop-end thread gauge head cannot be adjusted.

[0004] There is another structure in which the thread gauge probe head is retractable, such as the solution disclosed in the Chinese patent with publication number CN201672891U, entitled Retractable Thread Gauge. It realizes telescopic adjustment by installing an inner and outer sleeve that slides together on the side head of the thread gauge, and is equipped with a positioning and fixing structure. However, in this structure, the inner sleeve is prone to rotation during the telescopic process, making it difficult to align the positioning hole on the inner sleeve with the threaded hole on the outer sleeve, resulting in difficulty in adjustment.

[0028] The embodiment of the utility model provides a novel thread gauge, comprising a gauge body 10, a first thread gauge head 21, a first chuck 31, and a first locking cap 41;

[0029] One end of the first thread gauge head 21 is a first thread end 211, and the other end is a first connecting rod 212;

[0030] The gauge body 10 is provided with a cavity; the outer wall of one end of the cavity is provided with a first external thread end 12; the first external thread end 12 is provided with a first chuck 31;

[0031] The first connecting rod 212 is disposed in the first clamping head 31; the first connecting rod 212 can be partially or completely received in the cavity;

[0032] The first clamp 31 clamps the first connecting rod 212 by locking and clamping the first locking cap 41 and the first external thread end 12 .

[0033] When implementing it, Figure 1 , Figure 2 As shown, the novel thread gauge includes a gauge body 10, a first thread gauge head 21, a first chuck 31, and a first locking cap 41;

[0034] One end of the first thread gauge head 21 is a first thread end 211, and the other end is a first connecting rod 212;

[0035] The gauge body 10 is a hollow structure with two ends open, and the hollow structure of the gauge body 10 forms a cavity; a first external thread end 12 is provided on the outer wall of one end of the cavity; a first chuck 31 is provided in the first external thread end 12;

[0036] The first connecting rod 212 is disposed in the first clamp 31; the first connecting rod 212 can be partially or completely received in the cavity;

[0037] The first clamp 31 clamps the first connecting rod 212 by locking and clamping the first locking cap 41 and the first external thread end 12. The structures and locking principles of the first clamp 31 and the first locking cap 41 in this embodiment are all prior art and will not be described in detail.

[0038] like Figure 3 The first threaded end 211 is a schematic diagram of the current detection depth. When a deeper thread needs to be detected, the first locking cap 41 is rotated to make the first locking cap 41 and the first external threaded end 12 in an unlocked state, and then the first connecting rod 212 is pulled out for a distance according to the detection needs; thereafter, the first locking cap 41 is rotated in the opposite direction to make the first locking cap 41 and the first external threaded end 12 in a locked state, so as to hold the first connecting rod 212 tightly and fix the first connecting rod 212. The length of the first threaded end 211 after adjustment is as shown in FIG. Figure 4 The above adjustment structure is easy to adjust, and the connection between the first connecting rod 212 and the gauge body 10 is stable.

[0039] The new thread gauge provided by the embodiment of the utility model, through the structure combining the gauge body 10 with the first thread gauge head 21, the first chuck 31, and the first locking cap 41, can facilitate adjustment of the length of the first thread gauge head 21 according to the actual thread detection depth. The adjustment structure is simple and easy to operate, thus solving the problem of difficulty in adjusting the first thread gauge head 21.

[0040] Furthermore, it also includes a second thread gauge head 22, a second chuck 32, and a second locking cap 42;

[0041] One end of the second thread gauge head 22 is a second thread end 221, and the other end is a second connecting rod 222;

[0042] The cavity passes through the gauge body 10; the outer wall of the other end of the cavity is provided with a second external thread end 13; the second external thread end 13 is provided with a second chuck 32;

[0043] The second connecting rod 222 is disposed in the second clamp 32; the second connecting rod 222 can be partially or completely received in the cavity;

[0044] The second clamp 32 clamps the second connecting rod 222 by locking and clamping the second locking cap 42 and the second external thread end 13 .

[0045] When implementing it, Figure 2 As shown, the novel thread gauge further includes a second thread gauge head 22, a second chuck 32, and a second locking cap 42;

[0046] One end of the second thread gauge head 22 is a second thread end 221, and the other end is a second connecting rod 222;

[0047] The cavity runs through the gauge body 10; a second external thread end 13 is provided on the outer wall of the other end of the cavity; a second chuck 32 is provided in the second external thread end 13;

[0048] The second connecting rod 222 is disposed in the second clamp 32; the second connecting rod 222 can be partially or completely received in the cavity;

[0049] The second clamp 32 clamps the second connecting rod 222 by locking and clamping the second locking cap 42 and the second external thread end 13. The connection and adjustment principle of the gauge body 10, the second thread gauge head 22, the second clamp 32, and the second locking cap 42 are the same as those of the first thread gauge head 21, the first clamp 31, and the first locking cap 41.

[0050] In this embodiment, a first thread gauge head 21 and a second thread gauge head 22 are respectively arranged at both ends of the gauge body 10. The first thread gauge head 21 can be a through-end thread gauge head and the second thread gauge head 22 can be a stop-end thread gauge head. Two detection thread gauge heads are provided for detection.

[0051] Furthermore, the first locking cap 41 and the second locking cap 42 have different surface colors.

[0052] In specific implementation, the first locking cap 41 and the second locking cap 42 have different surface colors, and the through-end thread gauge head and the stop-end thread gauge head are distinguished by different colors.

Using color to distinguish is more obvious and easier to see than using numbers or graphic marks.

[0053] Furthermore, the surface color of the first lock cap 41 is green; the surface color of the second lock cap 42 is red.

[0054] Furthermore, the cross-sectional profiles of the gauge body 10 , one end of the first locking cap 41 , and one end of the second locking cap 42 are polygonal.

[0055] Furthermore, the cross-sectional profiles of the gauge body 10 , one end of the first locking cap 41 , and one end of the second locking cap 42 are hexagonal.

[0056] When implementing it, Figure 1 , Figure 2 As shown, the cross-sectional profiles of the gauge body 10, one end of the first locking cap 41, and one end of the second locking cap 42 are polygonal, such as hexagonal. Compared with the circular structure, the polygonal shape can make it easier for the user to exert force and conveniently rotate the locking cap.
