Internal structure of automatic measuring tape

Abstract

The invention provides an internal structure of an automatic measuring tape, which comprises a box body, a T-shaped buckle clamping slot arranged at the middle part inside the box body, a T-shaped buckle matched with the T-shaped buckle clamping slot, a rotating portion movably arranged at the outer side of the T-shaped buckle clamping slot in a sleeved manner, a tape winding position formed between the outer side of the rotating portion and the inner wall of the box body, an iron strap and a flexible tape, wherein the iron strap and the flexible tape are arranged at the tape winding position,one ends of the iron strap and the flexible tape are mutually connected, the top end of the rotating portion extends towards the outer side so as to form blocking positions perpendicular to the outerside wall of the rotating portion. The internal structure of the automatic measuring tape is provided with the blocking positions at the outer side of the top of the rotating portion so as to fix themoving trajectory of the iron strap and the flexible tape, so that the iron strap and the flexible tape are difficult to be disordered or dislocated, thus a problem of easy failure caused by long-term use is avoided, and the convenience performance of the automatic measuring tape is enabled to be higher.

Description

technical field [0001] The invention belongs to the technical field of measuring tools, in particular, the invention relates to an internal structure of an automatic tape measure. Background technique [0002] As a measuring tool in daily life, the tape measure is used in every aspect of our life. However, tape measures are often longer and convenient to use, but more troublesome to take back after use, so automatic tape measures have appeared again. The automatic tape measure is generally a box body, and the tape measure is neatly curled inside the box body. When it is used, it is pulled out to a corresponding length according to the need, and it is automatically retracted under the action of the internal resilience after use, or it can be retracted by pressing the button. However, there are also corresponding problems in the automatic tape measure in these two cases: the automatic tape measure retracted under the action of the internal springback force always exists, so t...
