Problems solved by technology

This "suspended" sample loading method is simple and easy to implement, and can meet the needs of general research and teaching, but it also has the following defects: 1) only one sample can be loaded at a time, which affects research efficiency and research quality; Supporting special occasions that are difficult to achieve, such as the traditional hydrogen evolution test method for the biodegradability of magnesium alloys, the application of the "suspension" sample loading method is limited; 3) When performing material performance tests in fluid media, such as using wire / wire If the software adopts the "suspension" method to hang the sample, the position of the sample will be "erratic" due to the double influence of its own gravity and the flow rate of the medium, which will have intricate effects on the test results, which is not conducive to the analysis of data and the determination of related laws. explore

Embodiment Construction

[0016] The specific implementation of the present invention will be further described below in conjunction with the drawings, but the implementation and protection scope of the present invention is not limited to this.

[0017] Such as figure 1 , figure 2 As shown, the upper sample loading device involved in the present invention is composed of a functional axis 1, three or more sample loading heads 2, and the same number of bridges 3 as the sample loading heads 2. One end of the connecting bridge 3 is connected with the lower end of the functional shaft 1, and the other end is connected with the upper end of the sample loading head 2, and there is a one-to-one correspondence between the sample loading head 2 and the connecting bridge 3. The functional shaft 1 and the sample loading head 2 are both cylindrical. The axis of the sample loading head 2 and the axis of the functional shaft 1 are parallel to each other. The sample loading head 2 has the same size, and its free ends a...

Abstract

The invention discloses an upper sample loader, which is a sample loading device capable of loading a test sample from the upper end of the test sample. The upper sample loader comprises a functional shaft, more than three sample loading heads and as many joining bridges as the sample loading heads, wherein one end of each of the joining bridge is connected with the lower end of the functional shaft and the other end of each joining bridge is connected with the upper end of one sample loading head; the sample loading heads are in one-to-one correspondence with the joining bridges; the functional shaft and the sample loading heads are all cylinders; and the axes of the sample loading heads are parallel to the axis of the functional shaft. The upper sample loader has the advantages of simple structure, convenient use, reliable performance, high universality and the like, can be widely applied to upper loading of the test sample, provides a beneficial solution for a test sample loading mode in upgrade scientific research and experimental teaching, particularly for solving the problem of the conventional suspension sample loading method in sample loading on special occasions, and is particularly suitable for loading and using of the sample in dynamic test of biodegradability of medical magnesium alloy.

Description

Technical field [0001] The invention belongs to the technical field of material / apparatus performance testing, and relates to a sample loading device for loading test samples from the upper end in scientific research and experimental teaching. Background technique [0002] The loading of test samples, especially solid test samples immersed in a liquid medium is a basic link in scientific research and experimental teaching, and has a direct and important impact on research results / teaching effects. The existing test sample loading method is mainly the "suspended" sample loading method with upper support, that is, a through hole is drilled in the test sample, and the thread / thread is used to vertically hang it on a supporting object such as a glass rod. This "suspended" sample loading method is simple and easy to implement, and can meet general research and teaching needs, but it also has the following shortcomings: 1) Only one sample can be loaded at a time, which affects research...
