3 results about "Sliding scale" patented technology

As shown in the reference exploded perspective view, this item has a plate-shaped sliding scale slidably disposed on a plate-shaped gauge body, length scales formed on the front and back of the gauge body, and the height of each scale line on the length scale is different in a stepped manner, i.e., a stepped scale, a reading indicator is formed on the surface of the sliding scale, and a finger hook projection with a roughly triangular prism-like ridge is fixedly disposed on the surface of the sliding scale. For example, as shown in reference diagram (1) showing the usage state, after butt welding a pair of base materials having a groove, to measure the height of the excess weld bead at the welded portion, the gauge body of this item is placed upright on one of the base materials, and the sliding scale is slid with the finger of the measurer relative to the gauge body, and the measurement point at the lower end of the sliding scale is brought into contact with the weld bead at the welded portion, and the excess weld bead height is read using the reading indicator on the surface of the sliding scale and the length scale on the surface of the gauge body. This welding gauge is used to measure the fillet height of a weld, and, for example, as shown in reference diagram (2) showing the state of use, after fillet welding of a flange material and a web material, the gauge body of this product is placed at an angle of 45°, and the measurement point at the tip of the sliding scale is brought into contact with the weld bead at the weld location, and the fillet throat thickness of the weld bead is measured using the reading indicator on the surface of the sliding scale and the length scale on the surface of the gauge body.Also, as shown in reference diagram (3) showing the state of use, after fillet welding of the flange material and a web material, the gauge body of this product is placed upright on the flange material, the rotating scale is rotated by a rotating pin, and the measurement point at the tip of the rotating scale is brought into contact with the intersection of the weld bead and the web material at the weld location, and the leg length of the weld bead is measured using the reading indicator on the surface of the rotating scale and the length scale on the back of the gauge body.

This utility model relates to the field of diameter measurement technology and proposes a digital display diameter ruler, including a first main scale and a slide ruler slidably disposed on the first main scale. The first main scale has a first measuring scale, and the slide ruler has a second measuring scale. After the slide ruler slides on the first main scale, it is used to measure the distance between the first and second measuring scales. A display component is provided on the slide ruler to display the distance between the first and second measuring scales. The first main scale has a groove in which the second main scale is slidably disposed. After the second main scale slides within the groove, it increases the measuring length of the first and second measuring scales. This invention solves the problem that existing equipment in the prior art cannot meet the requirements for these high-precision, large-range measurements.

The utility model belongs to the technical field of measuring rulers, and particularly relates to a special measuring ruler for construction engineering cost, which comprises three telescopic measuring rulers, each telescopic measuring ruler comprises a main ruler plate and a sliding ruler plate, each main ruler plate is internally provided with an inner sliding groove, two sides of each main ruler plate and two sides of each sliding ruler plate are provided with scale marks, and the scale marks are arranged in the inner sliding grooves. The end part of one main ruler plate and the end part of one sliding ruler plate are rotationally connected with grabbing plates; through cooperative use of the three telescopic measuring rulers, the two telescopic measuring rulers and the two telescopic measuring rulers, the grabbing plates and the connecting plates can change the rotation angle under the condition that the same distance is kept between the grabbing plates and the corresponding main ruler plate or the sliding ruler plate, so that the telescopic measuring rulers can conveniently adapt to corner measurement of different angles, and meanwhile, the two grabbing plates abut against a wall body, so that the three telescopic measuring rulers can be hung on the wall body; according to the invention, the three surfaces of the wall body can be conveniently measured by a worker at the same time, the worker can more visually and stereoscopically know the size information of the building structure body, and the measurement effect is better.
