Rapid testing tool for pulling force of self-tightening type binding tape

Abstract

The invention relates to a rapid testing tool for a pulling force of a self-tightening type binding tape. The rapid testing tool comprises a base, a wire winding rod and a limiting device, wherein thebase is internally provided with a through groove which is transversely arranged and is provided with openings at two ends; an opening, which is communicated with the inner part of the through groove, is formed in the upper end of the base; the wire winding rod is adaptively inserted into the through groove; the limiting device is mounted on the base and is close to the opening; after two ends ofthe binding tape winds around the wire winding rod, the binding tape stretches out from the opening and a stretching-out part of the binding tape is clamped through the limiting device. According tothe rapid testing tool provided by the invention, the wire winding rod, the through groove and the limiting device are matched, so that the binding tape is wound on the wire winding rod; in a processof upward lifting the wire winding rod, the tool can ensure that slippage and dislocation of the binding tape do not occur in an initial upward movement process; when the binding tape moves upward under the action of an external force, the wire winding rod slides upward along the through groove of the base, and a gap between the wire winding rod and the through groove of the base is reduced, so that a self-tightening process of the binding tape is realized.

Description

technical field [0001] The invention relates to the technical field of cable tie tension testing, in particular to a self-tightening tool for quick testing of cable tie tension. Background technique [0002] Cable ties are also called: cable ties, cable ties, cable ties, nylon cable ties, strapping straps, cable ties, electronic cable ties, etc. The main raw materials of packaging cable ties are polyethylene, polypropylene resin, and cold-rolled strip steel, and nylon and polyester are also used as raw materials. Cable ties have the properties of acid resistance, corrosion resistance, good insulation, not easy to age, and strong endurance. Widely used in binding items such as industry, agriculture, gardening, handicrafts, etc. [0003] The tensile strength of the cable tie is an important indicator to measure the mechanical properties of the cable tie. Before using the cable tie, it needs to pass multiple sets of tensile tests, and it can be put into use after meeting the ...

AI Technical Summary

Problems solved by technology

However, there are problems such as irregular testing and low efficiency in the cable tie tension test. For example, the simple tooling for clamping the cable tie causes stress concentration at the clamping position, resulting in a discrepancy between the fracture position of the cable tie and the theoretical position; , the cable tie will slip during the test
