Impact down penetration resistant instrument

Abstract

The invention relates to an impact down penetration resistant instrument, which is characterized by comprising guardrails, a mobile impact plate, an impact rod, a support, a fixed impact plate and a reciprocating driving mechanism, wherein the support is provided with a support oblique plane which forms a certain included angle with the horizontal plane; the mobile impact plate is placed on the support oblique plane; the plane of the mobile impact plate is vertical to the support oblique plane; the mobile impact plate is driven through the reciprocating driving mechanism and slides up and down on the support oblique plane; the fixed impact plate is arranged at the top of the support; the plane of the fixed impact plate is parallel to the plane of the mobile impact plate; a plurality of impact rods are respectively arranged on the face, which is opposite to the mobile impact plate, of the fixed impact plate; and the guardrails are arranged on the two sides of the mobile impact plate and are fixed on the fixed impact plate. The impact down penetration resistant instrument has a craft and reasonable structure; and by adoption of the impact down penetration resistant instrument, the impact strength and the impact area can be relatively uniform; the external force to a down product in a daily wearing process can be accurately reflected; and the test result is more accurate.

Description

technical field [0001] The invention relates to a test instrument, in particular to an impact-type anti-drilling instrument for detecting the down-drilling resistance of fabrics. Background technique [0002] In the actual production and use of down garments, the phenomenon of down garment leakage has been perplexing down garment manufacturers and consumers. Therefore, the anti-drilling properties of down clothing need to be tested. At present, the new anti-drilling standards for feather down in China: GB / T12705.1-2009 "Test method for anti-drilling of textile fabrics Part 1: Friction method" and GB / T12705.2-2009 "Anti-drilling of textile fabrics The test principles involved in Down Test Method Part 2: Turning Box Method are the friction method and the turning box method, but due to the unevenness of rolling, the down is easy to drill out from the suture, and the test error is relatively large. Contents of the invention [0003] The purpose of the present invention is to...
