Description

Technical Field

[0001] The utility model belongs to the technical field of plug gauges, and in particular relates to an improved large-diameter special plug gauge. Background Art

[0002] A plug gauge is a tool used to measure and inspect the size of a workpiece, and is mainly used to measure the diameter or gap size of a round hole or a cylindrical hole. The existing large-diameter special plug gauge includes a stop end and a through end, with a connecting rod fixedly installed between the stop end and the through end. When this plug gauge is used to detect a round hole, after detecting the through end, the plug gauge needs to be rotated to perform the stop end detection again, and the operation is relatively complicated. In addition, when detecting a round hole opened on the side of the workpiece, the plug gauge needs to be inserted horizontally into the round hole, which is inconvenient to operate. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an improved large-diameter special plug gauge, which can be bent to detect the round hole on the side of the workpiece and the through end and the stop end are arranged on the same side by bending to facilitate detection.

[0004] The utility model is realized by the following technical solutions:

[0005] An improved large-diameter special plug gauge comprises a stop end, a through end and a connecting cross frame assembly, wherein the connecting cross frame assembly comprises a cross frame, and side rotation blocks are arranged in pairs on the left and right sides of a groove opened in the lower part of the cross frame, and the outer ends of the side rotation blocks are connected to the cross frame pin shaft, and the left and right ends of the cross frame are integrally provided with connecting protrusions, and each of the connecting protrusions is fixedly installed with a hinge.

[0006] Preferably, one end of the stop end and the through end are both integrally provided with a connecting portion.

[0007] Preferably, a stop end connecting rod is threadedly connected to the connection portion of the stop end.

[0008] Preferably, a through-end connecting rod is threadedly connected to the connecting portion of the through-end.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. In the utility model, the setting of the stop end connecting rod, the through end connecting rod, the connecting cross frame assembly, the cross frame, the connecting protrusion, the side rotating block, and the hinge is conducive to bending to detect the circular hole on the side of the workpiece, and the through end and the stop end are arranged on the same side by bending to facilitate the detection of the hole of the workpiece.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, an improved large-diameter special plug gauge includes a stop end 1 and a through end 2, one end of the stop end 1 and the through end 2 are both integrally provided with a connecting portion 3, a stop end connecting rod 4 is threadedly connected at the connecting portion 3 of the stop end 1, a through end connecting rod 5 is threadedly connected at the connecting portion 3 of the through end 2, and a connecting cross frame assembly 6 is connected between the stop end connecting rod 4 and the through end connecting rod 5.

[0017] In this embodiment, combined with the Figure 2 As shown, the connecting cross frame assembly 6 includes a cross frame 61, and side rotating blocks 63 are arranged in pairs on the left and right sides of the groove opened in the lower part of the cross frame 61. The outer ends of the side rotating blocks 63 are connected to the cross frame 61 pin shaft, and the left and right ends of the cross frame 61 are integrally provided with connecting protrusions 62, and each of the connecting protrusions 62 is fixedly installed with a hinge 64. When measuring, the side rotating blocks 63 are rotated open to increase the stability of the cross frame 61 placed on the desktop. The user rotates the stop end connecting rod 4 and the through end connecting rod 5 to a vertical state through the connecting cross frame assembly 6 so that the stop end 1 and the through end 2 are in a vertical state. The user takes the workpiece and places it on the stop end 1 and the through end 2 for measurement, thereby avoiding the need to flip the plug gauge when measuring the through end and the stop end of the existing plug gauge.
