Description

Technical Field

[0001] The utility model belongs to the field of technical measurement and relates to pipeline standard detection, in particular to a scissor-type pipe diameter standard detection tool. Background Art

[0002] During the pipeline production process, standard inspections are required. Traditional methods for standard inspections of pipeline outer diameters include: direct measurement, that is, direct measurement using a vernier caliper, tape measure, or ruler. The operation is simple, but attention must be paid to the clamping strength of the caliper or the measurement accuracy may be limited due to factors such as the shape and curvature of the pipeline; another method is to use professional instruments for measurement, including photoelectric diameter gauges, laser diameter gauges, etc., which have the advantages of high degree of automation, fast measurement speed, and high accuracy. However, such inspection equipment is very expensive and requires professional technicians to operate. At the same time, the maintenance or repair costs are relatively high. Utility Model Content

[0003] The utility model aims to provide a scissor-type pipe diameter standard checking tool which has a simple structure, low cost, and is easy to use, and can quickly and efficiently detect the size standard of the outer diameter of a pipe.

[0005] A scissor-type pipe diameter standard gauge includes a first lever and a second lever, which are connected by a rivet to form a hinge structure, so that the first lever and the second lever can rotate around the rivet; the first lever is provided with a first handle and a first measuring ring; the second lever is provided with a second handle and a second measuring ring; the first measuring ring and the second measuring ring are respectively made according to the standard size of the outer diameter of the pipeline to be tested, and when the first measuring ring and the second measuring ring are closed, the outer diameter of the pipeline to be tested is the standard size.

[0006] Furthermore, the second hand-held part and the second measuring ring are fixedly connected via an upper connecting plate and a lower connecting plate.

[0007] Furthermore, the rivet fixing positions are the middle of the first lever and the middle of the upper connecting plate and the lower connecting plate of the second lever.

[0008] The beneficial effects of the utility model are as follows: the scissor-type pipe diameter standard gauge can perform batch detection of pipe outer diameter dimensions, has a simple structure, low manufacturing cost, is easy and convenient to operate, and produces accurate detection results, which can greatly improve work efficiency and reduce detection errors.

DETAILED DESCRIPTION

[0015] The following describes preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the examples described herein are only used to illustrate and strengthen the present invention, and are not used to limit the present invention.

[0016] like Figures 1 to 5 As shown, a scissor-type pipe diameter standard gauge includes a first lever 1 and a second lever 2. The first lever 1 and the second lever 2 are connected by a rivet 3 to form a hinge structure, so that the first lever 1 and the second lever 2 can rotate with the rivet 3 as the rotating axis.

[0017] The first lever 1 is an integral component, provided with a first handle portion 1.1 and a first measuring ring 1.2.

[0018] The second lever 2 comprises a second gripping portion 2.1, a second measuring ring 2.4, an upper connecting plate 2.2 and a lower connecting plate 2.3. The second gripping portion 2.1 and the second measuring ring 2.4 are fixedly connected via the upper connecting plate 2.2 and the lower connecting plate 2.3.

[0019] The rivet 3 is located in the middle of the first lever 1 and in the middle of the upper connecting plate 2.2 and the lower connecting plate 2.3 of the second lever 2. The first measuring ring 1.2 and the second measuring ring 2.4 are respectively semicircular and manufactured according to the standard outer diameter size of the pipeline to be measured. When the first measuring ring 1.2 and the second measuring ring 2.4 are closed, they are used to check whether the outer diameter size of the pipeline to be measured is qualified.

[0020] When using this gauge, hold the first hand-held part 1.1 and the second hand-held part 2.1, first separate the first measuring ring 1.2 and the second measuring ring 2.4, then place the pipe 4 to be measured between the first measuring ring 1.2 and the second measuring ring 2.4 and completely clamp them closed. At this time, observe the closure of the ends of the first measuring ring 1.2 and the second measuring ring 2.4, and verify whether there is a gap between the first measuring ring 1.2 and the second measuring ring 2.4 and the pipe 4 to be measured by whether light is transparent. If the ends of the first measuring ring 1.2 and the second measuring ring 2.4 are completely closed, If there is no gap between the first measuring ring 1.2 and the second measuring ring 2.4 and the pipe to be measured 4, the outer diameter of the pipe is consistent with the standard outer diameter; if the ends of the first measuring ring 1.2 and the second measuring ring 2.4 are completely closed, there is a gap between the first measuring ring 1.2 and the second measuring ring 2.4 and the pipe to be measured 4, then the outer diameter of the pipe is smaller than the standard outer diameter, and the larger the gap, the greater the gap; if the ends of the first measuring ring 1.2 and the second measuring ring 2.4 are not completely closed, then the outer diameter of the pipe is larger than the standard outer diameter, and the larger the gap between the ends of the first measuring ring 1.2 and the second measuring ring 2.4, the greater the gap.

[0021] Due to the adoption of the above technical solution, the inspection tool has the characteristics of simple structure, convenient operation and accurate reading, which can greatly improve work efficiency and reduce detection errors.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
