Description

Technical Field

[0001] This utility model relates to a measuring tool, specifically a portable sickle-shaped measuring tool, belonging to the field of measuring instrument technology. Background Technology

[0002] Uneven thickness on both sides during sheet metal rolling leads to poor sheet shape; deviation during finishing shearing; and cylinders failing to retract in time can all cause camber. Traditional measurement methods require three people to complete the measurement, and the distances at both ends must be calculated and calibrated, making it time-consuming and labor-intensive. In the context of reducing manpower and increasing efficiency, there is an urgent need to innovate a simple, time-saving, and labor-saving measurement tool that meets on-site requirements.

[0003] Currently, patent CN202048877U describes a rapid measuring tool for the sickle bend of thick plates, comprising a first fixed bracket, a second fixed bracket, a thin rope, and a thin rope tensioning device. This tool installs the first and second fixed brackets on the same side of the steel plate's head and tail, respectively. The guide hole of the thin rope is equidistant from the surface of the steel plate. The thin rope tensioning device tightens the rope, using it as a measurement baseline for rapid and accurate determination of the sickle bend in thick plates. Only one person is needed for measurement, resulting in high efficiency and providing strong evidence for improving the quality of thick plates. This effectively solves the problems of previous methods for measuring the sickle bend of steel plates, which lacked dedicated measuring instruments and resulted in inaccurate and inefficient data. However, this tool has a complex structure; for example, the thin rope tensioning device consists of ratchet teeth, ratchet wheels, a rocker arm, a handle, and a stop, making it inconvenient to use. Different lengths of thin rope are required for steel plates of varying lengths, and the fixed distance between the thin rope and the edge of the steel plate makes it difficult to adjust, resulting in poor applicability.

[0004] Therefore, developing a portable sickle bend measuring tool that can overcome the above defects has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0013] The technical advantages include multiple fixing slots on the head positioning strip, which effectively limit the distance for use. The sickle bend can be calculated by directly measuring the distance between the nylon thread and the edge of the steel plate. Furthermore, the multiple fixing slots and distances can be adjusted in real time according to the steel plate used, making it highly adaptable.

[0014] In the aforementioned portable sickle-shaped measuring tool, one side of the head plate covers part of the head body, while the other side extends out of the head body to hold the steel plate.

[0015] Technically, this utility model requires no other fixing components. It uses a head plate that extends out of the head body and is combined with nylon thread to fix the tool to the steel plate, making it convenient to use and saving time and effort.

[0016] In the aforementioned portable sickle bend measuring tool, the fixing components include a fixing block, a stud, and a nut. The stud is fixedly mounted on the head body, the fixing block is sleeved on the stud through a through hole, and the nut is threaded onto the stud to control the rotation of the fixing block and thus fix the take-up device.

[0017] In terms of technical benefits, this utility model uses simple fasteners to achieve the rotation and fixation of the take-up coil, which is simple in structure, easy to use, and saves time and effort.

[0018] In the aforementioned portable sickle-shaped measuring tool, the head and tail devices are made of stainless steel, which has a long service life.
