DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment: This embodiment provides a portable measuring instrument for accurately measuring eye position, see Figure 1-5 Specifically, it includes a portable box, an inner diameter measuring instrument 17 installed in the portable box, and a distance measuring component installed on the inner diameter measuring instrument 17. The portable box includes a top cover 1. Four fixed rods 11 are fixedly provided on the lower surface of the top cover 1. The lower ends of the four fixed rods 11 are fixedly provided with limit blocks 12. Moving blocks 13 are slidably provided in the four limit blocks 12. One end of the four moving blocks 13 is fixedly provided with a protective plate 14. A rubber plug 16 is inserted into the inner side of the protective plate 14. An end of the moving block 13 away from the protective plate 14 is provided with an inclined surface. The area of ​​the protective plate 14 is a quarter circle. An arc block is provided at the end of the positioning rod 15. A switch component is provided on the top cover 1;

[0025] The inner diameter measuring instrument 17 is a three-point inner diameter micrometer, which can measure the inner diameter of the punched hole and detect whether the punched hole is eccentric. The distance measuring component can measure the position of the punched hole on the product, and can also measure whether the outer wall of the cylindrical product is flat. The inner diameter measuring instrument 17 is inserted from the bottom of the portable box, and the moving block 13 is moved inward along the limit block 12 through the switch component. The moving block 13 drives the protective plate 14 to move synchronously. The arc block at the end of the positioning rod 15 inside the protective plate 14 contacts the outer wall of the inner diameter measuring instrument 17 to squeeze and fix the inner diameter measuring instrument 17. The four protective plates 14 are closed in a cylindrical shape, and then the rubber plug 16 is inserted into the inner side of the protective plate 14 to protect the measuring instrument. The portable box formed by the protective plate 14 not only occupies a small space and is easy to carry, but also fixes the measuring instrument more stably.

[0026] In the specific implementation process, Figure 2 and Figure 3 As shown, the switch assembly includes a screw rod 2 threadedly connected to the center of the top cover 1, a driving block 21 is fixedly disposed at the lower end of the screw rod 2, and first springs 22 are fixedly disposed on the inner walls of the four protective plates 14, and one end of the four first springs 22 is fixedly connected to the outer wall of the fixing rod 11;

[0027] The first spring 22 pulls the protective plate 14 toward the middle of the top cover 1, and the protective plate 14 drives the moving block 13 to always fit the driving block 21. When the screw 2 is rotated, the screw 2 rotates along the top cover 1, and the screw 2 drives the driving block 21 to rotate while also moving up and down. Since the driving block 21 is conical in shape, it drives the moving block 13 away from or close to the center position when moving up and down, allowing the protective plate 14 to open or close.

[0028] In the specific implementation process, Figure 4 and Figure 5 As shown, the distance measuring assembly includes a mounting ring 3 fixedly connected to the outer wall of the inner diameter measuring instrument 17, a rotating ring 31 is rotatably provided on the mounting ring 3, a connecting frame 32 is fixedly provided on the outer wall of the rotating ring 31, a rotating rod 33 is rotatably provided on the connecting frame 32, a scale 34 is slidably provided in the rotating rod 33, second springs 35 are fixedly provided on both sides of the end of the scale 34, one end of the two second springs 35 are fixedly connected to the outer walls of both sides of the rotating rod 33, a fixing plate is fixedly provided on both sides of the rotating rod 33 and the scale 34, one side of the fixing plate is connected to the second spring 35, a positioning assembly is provided at the end of the scale 34, the positioning assembly includes a fixing column 4 fixedly connected to the end of the scale 34, a measuring rod 41 is slidably provided in the fixing column 4, a bolt 42 is threadedly provided on the fixing column 4, and the end of the bolt 42 is fitted with the outer wall of the measuring rod 41;

[0029] The rotating rod 33 is rotated, and the bottom of the rotating rod 33 is fitted with the bottom of the connecting frame 32. The rotating rod 33 is perpendicular to the inner diameter measuring instrument 17. By pulling the measuring rod 41, the measuring rod 41 moves along the fixed column 4. When the bolt 42 is rotated, the bolt 42 is fitted with the outer wall of the measuring rod 41, and the position of the measuring rod 41 is fixed, so that the measuring rod 41 is fitted with the edge of the outer wall of the product. By observing how much the scale 34 leaves the rotating rod 33, it is determined how far the punching eye is from the edge of the product, and the distance between the two eye positions can also be measured. Through the pulling force of the second spring 35, the scale 34 can drive the measuring rod 41 to always be located at the edge of the product, which is convenient for measurement. By rotating the rotating ring 31, the measuring rod 41 is driven to rotate along the outer wall of the cylindrical product to measure whether the cylindrical outer wall is flat.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] Insert the inner diameter measuring instrument 17 from the bottom of the portable box. When the screw 2 is turned, the screw 2 rotates along the top cover 1. The screw 2 drives the driving block 21 to rotate and move up and down at the same time. Since the driving block 21 is in a conical shape, it moves downward, allowing the moving block 13 to move closer to the center position, allowing the protective plate 14 to be closed, and the arc block at the end of the positioning rod 15 inside the protective plate 14 contacts the outer wall of the inner diameter measuring instrument 17 to squeeze and fix the inner diameter measuring instrument 17. The four protective plates 14 are closed in a cylindrical shape, and then the rubber plug 16 is inserted into the inner side of the protective plate 14 to protect the measuring instrument. The portable box formed by the protective plate 14 not only occupies a small space, but is also easy to carry.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
