Description

Technical Field

[0001] The utility model relates to an elastic band elongation ratio detection device. Background Art

[0002] When testing elastic bands in garment factories, it is usually done manually by marking 10 cm on the elastic bands, then stretching the elastic bands with both hands, measuring the stretched length with a ruler and calculating the elongation ratio. This process is difficult to complete by one person, and is not only inefficient, but also has low measurement accuracy. Only one elastic band can be tested at a time. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide an elastic band elongation ratio detection device.

[0004] In order to achieve the above-mentioned purpose, the elastic band elongation ratio detection device of the utility model comprises a work surface, on which an elastic band fixing device is arranged, and the elastic band fixing device comprises a fixed base plate, on which a fixed splint is arranged by means of clamping and hinged connection; a marking and printing device is arranged on the work surface 10 cm above the position corresponding to the elastic band fixing device; and a measuring ruler is arranged on the work surface corresponding to the right side of the elastic band fixing device.

[0005] Furthermore, the marking and printing device consists of a powder box and a marking line; the powder box is made of metal, has an open top, is filled with drawing powder, is fixed to the work surface with bolts, and has two small holes with a diameter of 2 mm at the bottom of the powder box; the marking line is a cotton rope.

[0006] Furthermore, the position of 26cm-32cm on the measuring ruler is marked as a green area.

[0007] Furthermore, a side of the fixing splint contacting the elastic band is provided with serrations.

[0008] The utility model develops and designs an elastic band elongation ratio detection device, which can fix one end of the elastic band on the work surface, and use a marking printing device to easily and accurately draw a mark position print, stretch the elastic band, and see whether the mark print can reach the green area on the measuring ruler, so as to quickly determine whether the elastic band elongation ratio index is qualified. Through practical application, this device can be applied to elastic bands of any specifications, and can simultaneously detect multiple elastic bands at a time, thereby improving detection efficiency and accuracy, reducing operation difficulty, and being able to meet the detection needs of various elastic band elongation ratio indicators.

[0014] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] like Figures 1 to 3 The embodiment of the utility model shown comprises a work surface 1, an elastic band fixing device 2, a marking drawing device 3, and a measuring ruler 4.

[0017] The elastic band fixing device is provided with a fixing base plate 21 and a fixing clamping plate 22, the fixing base plate is fixed to the work surface 1 by bolts; one end of the elastic band is fixed to the fixing base plate 21 by the fixing clamping plate 22. The marking drawing device 3 is fixed to the work surface 1 by bolts.

[0018] The marking and printing device consists of a powder box and a marking line. The powder box is made of metal, has an open top, is filled with drawing powder, and is fixed to the work surface with bolts. The marking line is generally a cotton string with a diameter of 1-2 mm, and one end of the cotton string is fixed at a position of 10 cm on the work surface; the marking line is stained with drawing powder after passing through the powder box, and the marking line is stretched and then pulled to print the drawing powder on the elastic band. The distance between the position of the marking line and the fixed position of the elastic band is 10 cm.
