Title:
HIGH-MOLECULAR MATERIAL DENSITY TESTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/246855
Kind Code:
A1
Abstract:
Disclosed in the present invention is a high-molecular material density testing apparatus, relating to the technical field of high-molecular material testing. The present invention comprises a workbench, wherein a sliding groove is provided in an upper surface of the workbench, and supporting columns are fixedly connected to four corners of a lower surface of the workbench; a moving plate is slidably connected in the sliding groove; a rotating rod is rotatably connected to a side wall of the moving plate; one end of the rotating rod penetrates the moving plate and is fixedly connected to a clamping block; a sliding column is slidably connected to an upper surface of the clamping block; one end of the sliding column penetrates an upper inner wall of the clamping block and is fixedly connected to a clamping plate; a reset spring is sleeved on an outer surface of the sliding column; a fixing column is fixedly connected to the upper surface of the workbench; and a density tester is fixedly connected to a lower surface of a telescopic rod. The present invention solves the problems whereby most existing testing devices can only test the density of a certain single surface of a high-molecular material to be tested during testing, resulting in the possibility of errors in the density of the high-molecular material to be tested, and that it is difficult to test the density of each surface of the high-molecular material to be tested.
