Description

Technical Field:

[0001] The present invention belongs to the field of textile testing, and more specifically, relates to the test for discriminating three-dimensional ornaments at the end of cord for the safety testing technology of cord for infants' and children's textiles. Background Art:

[0002] In daily life, infants and children need to use and wear textile products such as clothing to protect the skin, keep warm, and be beautiful and decorative. When designing clothing for infants and children, fashion designers will design some cords on the surface and inside of the clothing to meet the functional requirements of adjusting the clothing size and the aesthetic requirements of decorating the clothing. Infants and children are active and have weak safety awareness. When getting off the car or getting out of the elevator door, if the cord on the clothing is too long or there is a three-dimensional ornament at the end of the cord, it may be caught by the car door or elevator, posing safety risks such as dragging and falling. In addition, when infants and children are playing, if the cord on the clothing is too long or there is a three-dimensional ornament at the end of the cord, it is also very easy to hook onto entertainment facilities, leading to the occurrence of serious accidents. Based on this, China has formulated standards such as GB 31701 "Safety Technical Code for Textile Products for Infants and Children" and GB / T 22705 "Safety Requirements for Cords and Drawstrings on Children's Clothing", which stipulate the safety requirements for cords used on textile products for infants and children, so as to prevent cords that are too long or have three-dimensional ornaments at the end of the cord from harming infants and children.

[0003] The standard only requires that three-dimensional ornaments cannot be used at the end of the cord, but does not make quantitative requirements for judging whether it is a three-dimensional ornament, mainly relying on the experience and understanding of the testers to make judgments, with strong subjectivity. When judging whether there is a three-dimensional ornament at the end of the cord and whether the cord has safety risks, the conclusions of each testing institution and tester are not unified and controversial. Summary of the Invention:

[0004] Based on the requirements and interpretations of three-dimensional ornaments at the end of the cord in standards such as GB 31701, GB / T 22705, and the Implementation Guide of GB 31701 "Safety Technical Code for Textile Products for Infants and Children", the present invention focuses on designing a test device for discriminating three-dimensional ornaments at the end of the cord, and provides a test method based on this device. The present invention can conduct experimental tests on whether there are three-dimensional ornaments at the end of the cord used on textile products for infants and children, quantify the process of discriminating whether it is a three-dimensional ornament at the end of the cord, solve the problem that the conclusions of each testing institution and tester are not unified when judging whether there is a three-dimensional ornament at the end of the cord and whether the cord has safety risks, and unify the test conclusions. The present invention is suitable for various cords used on textile products for infants and children, solves the controversy over the judgment of three-dimensional ornaments at the end of the cord, and reduces the error caused by subjective factors to the test results.

[0005] To achieve the above-mentioned invention object, the present invention provides the following technical solutions:

[0006] A test device for identifying three-dimensional ornaments at the end of a cord includes a device base and a device bracket; the device base is a support base, and an upper part thereof is provided with a device bracket and a lower fixture fixing base; the device bracket is a support main body, a slide rail is installed on the front surface of the upper part, a rocker is installed on the side surface, and the lower part is concave.

[0007] Further, a spiral hole is embedded in the middle of the lower fixture fixing base, and a lower fixture is installed on the upper part.

A hook is installed at the lower part of the tensiometer, and the hook is used to hang and fix an upper fixture, and the upper fixture is used to fix a test object.

[0008] Further, the rocker controls the up and down movement of the tensiometer. The tensiometer drives the hook, the hook drives the upper fixture, and the upper fixture drives the test object to move upward. The tensiometer is used to measure the force value of the upper fixture pulling the test object out of the lower fixture.

[0010] Further, the bottom of the lower fixture is a threaded base, the middle part is a fixture base, and the upper part is a fixture clamp; the threaded base can be installed in the spiral hole of the lower fixture fixing base and fixed by rotating the lower fixture; the fixture clamp is divided into left / right clamps, and the upper cross-section of the left / right clamps is a smooth surface; the fixture clamp and the fixture base are connected by three screws; a gear is placed in the middle of the fixture clamp, and a full-threaded bar sequentially passes through the left clamp, the gear and the right clamp of the fixture clamp; rotating the gear can control the left / right clamps of the fixture clamp to move on the full-threaded bar to both sides of the gear, so as to control the upper spacing of the fixture clamp and simulate slits of different widths.

[0011] Further, both the device base and the device bracket are made of high-strength metal, and the device base and the device bracket require high-strength performance to prevent irreparable damage to the device during the test process.
