[0024] In order to take into account both the detection accuracy and detection efficiency of aperture detection, this technical solution proposes a plug gauge, including:

[0025] Fixed seat 100;

[0026] At least two needle gauge assemblies 200 are disposed on the fixing base 100 , and each needle gauge assembly 200 has a different size to detect apertures of different sizes.

[0027] Compared with the prior art, in the technical solution of the utility model, the plug gauge includes a fixed base 100, on which at least two needle gauge assemblies 200 are arranged, and each needle gauge assembly 200 has a different size to detect apertures of different sizes. In this way, the plug gauge can be used to detect apertures of multiple sizes without repeatedly replacing the needle gauge, thereby improving the detection efficiency while ensuring the detection accuracy.

[0028] Specifically, Figure 1The plug gauge includes a fixing base 100, which is a rectangular structure. A needle gauge assembly 200 is arranged on the fixing base 100. At least two needle gauge assemblies 200 are arranged on the fixing base 100, and the size of each needle gauge assembly 200 is different. Each needle gauge assembly 200 may include two needle gauges with adjacent sizes. In this way, each needle gauge assembly 200 can detect a range of apertures, and the plug gauge can detect at least two ranges of apertures. When using the plug gauge, it is only necessary to detect the holes with different needle gauge assemblies 200 to realize the detection of apertures of different sizes. There is no need to replace other needle gauges during the detection process, so the detection speed can be improved. In addition, the use of needle gauge detection also ensures the detection accuracy.

[0029] Further, the needle gauge assembly 200 includes a go gauge 210 and a stop gauge 220, and the go gauges 210 of at least two needle gauge assemblies 200 have different sizes, and the stop gauges 220 of at least two needle gauge assemblies 200 have different sizes. Figure 1 In the present embodiment, the needle gauge assembly 200 includes a go gauge 210 and a stop gauge 220, and the size of the go gauge 210 and the size of the stop gauge 220 of each needle gauge assembly 200 are different. Thus, the go gauge 210 and the stop gauge 220 of each needle gauge assembly 200 can be set as the minimum limit size and the maximum limit size of the hole to be measured. Thus, one needle gauge assembly 200 can be used to determine whether the hole to be measured meets the processing requirements, thereby improving the detection efficiency. By arranging a plurality of the above-mentioned needle gauge assemblies 200 on the fixing seat 100, the detection of a plurality of holes of different sizes can be realized, thereby expanding the application scope of the plug gauge and improving the detection efficiency of a plurality of holes.

[0030] Furthermore, the go gauge 210 and the stop gauge 220 of each needle gauge assembly 200 are disposed adjacent to each other on the fixing seat 100. Figure 1 In the present embodiment, the go gauge 210 and the stop gauge 220 of each needle gauge assembly 200 can be arranged adjacent to each other. Thus, when inspecting the hole to be tested, the travel of the plug gauge can be shortened, thereby further improving the inspection efficiency. At the same time, it is also convenient to easily distinguish the go gauge 210 and the stop gauge 220 in different needle gauge assemblies 200.

[0031] Furthermore, the fixing seat 100 is a rectangular parallelepiped structure, and each plug gauge and each stop gauge 220 are arranged on different surfaces of the fixing seat 100. Figure 1 In the present embodiment, the fixing base 100 is a rectangular parallelepiped structure, and each plug gauge and each stop gauge 220 on the fixing base 100 are arranged on different surfaces of the fixing base 100, so that the plug gauge can be suitable for the detection of holes on a large plane, and prevents other plug gauges or stop gauges 220 from interfering with the large plane and affecting the detection.

[0032] Furthermore, the needle gauge assembly 200 has a chamfered structure, and the chamfered structure is provided on the peripheral edge of the end of the go gauge 210 away from the fixing seat 100 and the peripheral edge of the end of the stop gauge 220 away from the fixing seat 100. In this embodiment, the peripheral edges of the end of the go gauge 210 and the stop gauge 220 of the needle gauge assembly 200 away from the fixing seat 100 can be provided with a chamfered structure, so that the go gauge 210 and the stop gauge 220 can be more easily matched with the hole to be tested under the guidance of the chamfer during detection, thereby improving the detection efficiency.

[0033] Furthermore, an identification body 110 is recessed on the mounting seat, and an identification body 110 is disposed adjacent to each needle gauge assembly 200, and the outer dimensions of each identification body 110 are different. In order to facilitate the distinction between different needle gauge assemblies 200, an identification body 110 may be recessed on the mounting seat, and an identification body 110 may be disposed adjacent to the go gauge 210 and the stop gauge 220 of each needle gauge assembly 200. The identification body 110 may be the specification of the go gauge 210 or the stop gauge 220, or may be other identification that facilitates identification of the specification of the needle gauge assembly 200. The provision of the identification body 110 can facilitate personnel to determine the specification of the needle gauge assembly 200 and the size of the hole to be measured, and is also convenient for novices to use the plug gauge.

[0034] Furthermore, a support body 120 is convexly provided on the fixing seat 100, and one end of the plug gauge and / or one end of the stop gauge 220 penetrates into the support body 120. In order to improve the strength of the plug gauge, a support body 120 is further convexly provided on the fixing seat 100, and the support body 120 can be integrally formed with the fixing seat 100. The support body 120 can be an annular structure, and the plug gauge or the stop gauge 220 can penetrate into the support body 120. In this way, the support body 120 can provide support for the side walls of the plug gauge and the stop gauge 220, improve the connection strength between the fixing seat 100 and the needle gauge assembly 200, and thus improve the reliability of the plug gauge.

[0035] Furthermore, an anti-skid body is convexly provided on the outer peripheral wall of the fixing seat 100. In this solution, an anti-skid body can be convexly provided on the outer peripheral wall of the fixing seat 100, and a plurality of anti-skid bodies can be arranged at intervals, so that the friction between the fixing seat 100 and the hand can be increased when holding, the anti-skid performance can be improved, and the plug gauge can be prevented from accidentally falling out of the hand and affecting the safety of use.

[0036] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
