Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tape measures, in particular to a high-precision tape measure with a magnetic ruler hook. Background Art
[0002] The tape measure is a commonly used length measuring tool in daily work and life. The steel tape measure that is often seen and used in daily life is an essential measuring tool in the construction and decoration industry, and is also one of the essential tools in the home.
[0003] The tape measure mainly uses two measurement methods: hook measurement and top measurement. When the front end of the tape measure hook is against the object to be measured, it is top measurement; when the tape measure hook is hooked on the object to be measured, it is hook measurement. In order to eliminate the error caused by the thickness of the hook, the tape measure usually leaves a certain amount of movement at the connection between the hook and the tape. When measuring with the hook, the hook and the tape are pulled apart by a certain distance, and when measuring with the top, the hook and the tape are compressed by a certain distance.
[0004] However, in daily operations, when the measuring distance is far, the ruler hook is easy to separate from the object being measured, and manual pressing operation is required on the ruler hook, which increases the difficulty of measurement. At the same time, when measuring at a long distance, the ruler tape is also required to be pressed against the ruler hook manually to eliminate the error caused by the thickness of the ruler hook. The operation is cumbersome and it is easy to cut fingers with the ruler tape during the operation.
[0005] Therefore, in view of the shortcomings of the prior art, it is necessary to design a high-precision tape measure with a magnetic ruler hook to solve the above problems.
[0006] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the utility model. Utility Model Content
[0007] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to disclose a high-precision tape measure with a magnetic ruler hook, which is used to save time and manpower in measurement operations and improve measurement accuracy.
[0008] The utility model discloses a high-precision tape measure with a magnetic hook, comprising a tape measure body, a reading tape and a hook, wherein the reading tape is installed in the tape measure body, the tape measure body is provided with an opening for the reading tape to enter and exit, and the hook is arranged at the front end of the reading tape; a mounting hole is provided at the front end of the hook, and a strong magnet is riveted in the mounting hole. When measuring by hook or by top measurement, the strong magnet can be used to replace manual adsorption on the object to be measured, thereby improving the convenience of the measurement operation.
[0009] Preferred technical solution: The front end of the reading tape is provided with a hook measurement positioning hole and a top measurement positioning hole, and the hook is provided with a hook measurement locking hole and a top measurement locking hole. The hook measurement positioning hole and the hook measurement locking hole are pluggable connected by a latch, which is used to position and fix the hook and the reading tape when the hook measurement test is adopted; the top measurement positioning hole and the top measurement locking hole are also pluggable connected by a latch, which is used to position and fix the hook and the reading tape when the top measurement test is adopted. According to the hook measurement and the top measurement, the corresponding connection method is selected to lock the reading tape and the hook, so as to eliminate the error caused by the thickness of the hook.
[0010] The preferred technical solution: the bolt is a stepped bolt, including a pin cap, a positioning column and a connecting column arranged in sequence. The end of the connecting column is detachably provided with a fixing plate, which prevents the bolt from being separated from the reading tape and the ruler hook; the outer diameter of the connecting column is the same as the inner diameter of the hook measurement positioning hole and the top measurement positioning hole; the outer diameter of the positioning column is the same as the inner diameter of the hook measurement locking hole and the top measurement locking hole; the outer diameter of the positioning column is larger than the outer diameter of the connecting column. It is convenient to switch the connection mode between the ruler hook and the reading tape.
[0011] Preferred technical solution: The radius difference between the positioning column and the connecting column is greater than the thickness of the ruler hook. After one of the hook locking hole or the top locking hole is locked by the latch, the latch on the other one only needs to be pulled upward a certain distance so that the connecting column part corresponds to the outer hole wall to avoid interference.
[0012] Preferred technical solution: The connection between the positioning column and the connecting column adopts a conical transition to facilitate the insertion and removal of the latch.
[0013] Optimal technical solution: There are two strong magnets on the front end hook surface of the ruler hook to improve the stability of magnetic attraction.
[0014] Preferred technical solution: The front end of the reading tape is connected to the tape hook via rivets to improve the stability of the connection.
[0015] Due to the application of the above technical solution, the high-precision tape measure with a magnetic ruler hook of the utility model has the following beneficial effects:
[0016] (1) Strong magnets are used instead of manual operation to increase the connection stability between the ruler hook and the object being measured, thus improving the convenience of measurement operation;
[0017] (2) The connection mode between the reading tape and the hook is switched by plugging and pulling out the stepped pin, which is used to match the corresponding hook measurement and top measurement operations, eliminate the error caused by the thickness of the hook, and improve the measurement accuracy.
