Embodiment Construction

[0008] As shown in the figure: a pressing block 2 for clamping the material 6 is arranged on the upper part of the cantilever frame 1 , and a pressing mechanism for pushing the pressing block 2 to move is arranged between the pressing block 2 and the cantilever frame 1 . In the pressing mechanism, one end of the threaded part is connected with the threaded hole provided on the cantilever frame 1, and there is a through hole on the pressing block 2, and the pressing block 2 is sleeved on the outer end of the threaded part by using the through hole. Nut 3 is arranged on the threaded member outside briquetting block 2. There is a fabric 6 between the briquetting block 2 and the cantilever frame 1, a hook 4 is arranged under the fabric 6, and a weight 5 is arranged below the hook 4.

[0009] When working, first cut a piece of fabric sample, fix the upper end of the sample fabric 6 on the head of the cantilever bracket 1, tighten the round nut 3 to drive the pressing block 2 to cla...

Abstract

The invention relates to lining test equipment, specifically to a testing device for testing the coefficient of extension of the ceiling lining of automobile. According to the technical proposal provided by the invention, a bundle which is used for clamping the lining is equipped on the upper part of a suspension arm frame. A clamping mechanism which is used for pushing the bundle to move is equipped between the bundle and the suspension arm frame. In the clamping mechanism, one end of a screw thread piece is matched and connected with a screw thread hole equipped on the suspension arm frame, a through hole is provided on the bundle, and the bundle is sleeved on the outer end of the screw thread piece. A screw nut is provided on the screw thread piece outside the bundle. The invention has the advantages that the structure is simple, compact and reasonable; different linings of products can be tested on the device, and the real state of the goods delivered can be accurately reflected, the performance of the raw material of the product can be accurately grasped and the fraction defective can be promptly discovered, and the quality of the product can be improved.

Description

technical field [0001] The invention relates to a fabric testing device, in particular to a testing device for the elongation rate of a car ceiling fabric. Background technique [0002] At present, in the elongation inspection process of automobile headliner fabrics, it generally relies on the inspection report of the supplier or the inspection by a professional unit. This kind of external test results, on the one hand, cannot accurately know whether the supplier's incoming materials meet the requirements, second, whether it is applicable under our production conditions, and third, requires a certain amount of operating time and testing costs, that is, it cannot solve the problem in time Too much time wasted. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a simple, compact and reasonable structure; accurate testing, timely feedback on site, and can improve the quality of the car roof fabric...
