Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an in-situ metrological verification mechanism for a pressure gauge, comprising: the connecting component 2 is arranged on one side of the watch body 1, the connecting component 2 comprises a bottom plate 22 which is arranged on the surface of the checking pipe 21 and is connected with the surface of a top plate 23 in a fitting mode, the bottom plate 22 and the top plate 23 are both sleeved on the surface of the checking pipe 21, sliding columns 24 fixedly connected with thread plates 25 are arranged on the surfaces of the bottom plate 22 and the top plate 23 in a sliding mode, and meanwhile the sliding columns 24 and the thread plates 25 are arranged on the surfaces of the bottom plate 22 and the top plate 23 at equal angles.

As shown in fig. 1 to 4, when the top plate 23 and the bottom plate 22 are rotated relative to each other, the slide column 24 can be slid in a groove formed in the surface of the bottom plate 22, and the slide column 24 and the screw plate 25 can be prevented from rotating on the surface of the bottom plate 22 and being unable to be connected to the watch body 1 effectively due to the elliptic shape of the slide column 24.

As shown in fig. 1-4, the arc-shaped groove formed on the surface of the top plate 23 can drive the sliding column 24 to effectively slide on the surface of the bottom plate 22, so that the screw plate 25 can effectively fix the watch body 1.

As shown in fig. 1 to 4, the screw plate 25 can be fixed by working between the stud 31 and the stabilizing block 33 when the strut 24 needs to be fixed by the stabilizing block 33, thereby ensuring the stability of the connection between the screw plate 25 and the watch body 1.

As shown in fig. 1 to 4, the connection between the stud 31 and the hole formed on the surface of the stabilization block 33 can be performed, so that the stabilization block 33 can be pulled when the stud 31 is rotated.

The working principle is as follows: when the watch body 1 needs to be checked, the watch body 1 and the check pipe 21 arranged in the connecting assembly 2 can be aligned, then the bottom plate 22 and the top plate 23 can slide on the surface of the watch body 1, the sliding column 24 is pushed to be close to the watch body 1, then the bottom plate 22 and the top plate 23 can be twisted to enable the two to rotate relatively, at the moment, the arc-shaped groove formed in the surface of the top plate 23 can push the sliding column 24 to slide in the strip-shaped groove formed in the surface of the bottom plate 22, and each thread plate 25 gradually approaches to the direction of the watch body 1, when each thread plate 25 is contacted with the watch body 1, the watch body 1 can be rotated, and thread rotation is generated between the watch body 1 and each thread plate 25, at the moment, the pulling force generated between the watch body 1 and the thread plates 25 can drive the bottom plate 22, the top plate 23, the sliding column 24 and the thread plates 25 to simultaneously move towards the direction of the watch body 1 along the surface of the check pipe 21 until the surface of the top plate 23 is tightly attached to the outer edge of the check pipe 21, and the check pipe 21 is butted;

then, the stud 31 arranged in the reinforcing component 3 can be rotated to enable the stud 31 and the stabilizing plate 32 to generate threaded rotation, and the stabilizing block 33 is gradually pushed by the stud 31 to move towards the direction of the slide column 24 until the stabilizing block 33 and the slide column 24 are tightly attached, so that the slide column 24, the threaded plate 25 and the watch body 1 can be prevented from being loosened.

It should be noted that: the rubber ring is arranged at the joint of the watch body 1 and the detection tube 21, so that the condition that the detection structure is inaccurate due to the leakage of gas or liquid between the watch body 1 and the detection tube 21 can be avoided when the connection is generated between the detection tube 21 and the chassis 22.

In the above, the present invention is only a preferred embodiment, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the equivalent embodiments modified or modified by the above-mentioned technical contents to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention will still fall within the protection scope of the technical solution of the present invention.
