Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a measuring ruler for engineering detection. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. A building structure refers to a project with a roof, beams, columns, walls, foundations, and internal space that can meet people's needs for production, residence, study, and public activities. When a house is built, building materials need to be laid on the ground. Therefore, a measuring ruler is needed to measure and mark construction supplies such as boards to facilitate cutting of building materials.

[0003] When measuring, a common measuring ruler needs to first place the ruler itself on the surface of the object to be measured, and then obtain the measurement information and mark it through the scale lines. However, this method marks the surface of the object to be measured according to the scale lines after measurement, and the measuring ruler itself has no marks. As a result, when the same length needs to be obtained later, it is necessary to compare the readings again, which makes the measuring ruler very inconvenient to use and cannot meet the working requirements of the measuring ruler. For this reason, a measuring ruler for engineering inspection is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a measuring ruler for engineering inspection to solve the technical problem that, since the surface of the object to be measured is marked according to the scale lines after measurement, it is necessary to re-compare the readings when the same length is needed later.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a measuring ruler for engineering inspection, comprising:

[0008] A ruler plate, wherein a slide groove is provided in the middle of the ruler plate, an adjustment seat is inserted into the left side of the slide groove, and a vernier caliper is inserted into the right side of the adjustment seat in the slide groove;

[0009] A mounting seat is installed on the top right side of the adjustment seat, the top left side of the vernier holder is connected to a mounting platform, and the front middle position of the mounting platform is connected to a scale needle;

[0010] The scale line is installed on the top front side of the ruler plate. A rotating shaft is inserted inside the mounting seat, and a roller is coaxially installed on the right end of the rotating shaft. A screw is coaxially connected to the right side of the roller, and the right part of the screw is screwed to the inside of the mounting platform.

[0011] Preferably, the slide groove, adjustment seat and vernier card seat are all trapezoidal in shape, and the left and right sides of the bottom of the adjustment seat and vernier card seat are rounded, which improves the stability of the adjustment seat and vernier card seat when they move left and right.

[0012] Preferably, the shape of the scale needle is L-shaped, and the color of the scale needle is different from the color of the scale lines, so that the scale needle can be distinguished between the scale lines, which facilitates reading.

[0013] Preferably, the diameter of the roller is larger than the rotating shaft and the screw, and a convex strip is arranged on the outer circumference of the roller to facilitate the rotation of the roller.

[0014] Preferably, a bolt is screwed into the middle position of the adjustment seat, paddles are installed on both the left and right sides of the top of the bolt, and a ball bearing is inserted into the lower side of the bolt.

[0015] Preferably, a connecting pin is inserted into the inner ring of the ball bearing, and a base is coaxially installed at the bottom end of the connecting pin. A circular ring is connected to the lower left end of the ruler plate, and the base can be driven to move up and down by rotating the bolt, so that the base contacts the inner wall of the slide groove, and the adjustment seat can be limited to prevent further movement after the scale needle moves to the specified position.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a measuring ruler for engineering inspection, which has the following

[0018] Beneficial effects:

[0019] The measuring ruler for engineering inspection drives the left and right movement of the vernier cassette by pushing the adjustment seat, so that the scale needle can be driven to move and read through the scale lines. After reading the large scale, the screw can be driven to rotate by turning the roller, so that the vernier cassette and the scale needle can be driven to make fine adjustments, which is convenient for accurate reading of small scales. At the same time, since the vernier cassette and the scale needle do not move when the adjustment seat is not pushed and the roller is not turned, the scale needle always hovers at the position of the scale line, which not only facilitates recording, but also allows quick marking when performing measurements of the same specifications and large quantities, without the need to read each time, thereby improving the convenience of using the measuring ruler.
