The sample loader comprises a functional shaft, more than three sample loading heads and connecting bridges, wherein the number of the connecting bridges is equal to that of the sample loading heads; one end of each connecting bridge is connected with the lower end of the functional shaft, and the other end of each connecting bridge is connected with the upper end of each sample loading head; the sample loading heads and the connecting bridges are in corresponding relations one by one; the functional shaft and the sample loading heads are all cylinders; and the axes of the sample loading heads and the axis of the functional shaft are mutually parallel. The up position sample loader in the utility model has the advantage of simple structure, is convenient in use, reliable in performance and strong in versatility, and can be widely applied to up position loading of test samples. The up position sample loader in the utility model also provides a beneficial solution for upgrading the test sample loading mode in scientific research and laboratory teaching, and especially for solving the problems encountered in sample loading on special occasions by the traditional suspension type sample loading method, and the up position sample loader is especially suitable for loading samples in a dynamic test for the biodegradability of a medical magnesium alloy.
Description
Technical field
The utility model belongs to material/apparatus technical field of performance test, relates to being used in a kind of scientific research and the experimental teaching from the test specimen upper end its load sample device that loads.
Background technology
The especially default loading that immerses the solid test sample of liquid medium of test specimen is the basic link in scientific research and the experimental teaching, and result of study/teaching efficiency is had directly and significant effects.Existing test specimen load mode is promptly bored a through hole based on " suspension type " load sample method of upper support on test specimen, be behind filament/line it is hung vertically on supporting object such as the glass bar etc.Simple, the easy row of this " suspension type " load sample method, can satisfy general Study, teaching needs, but also have following defective simultaneously: 1) once can only load a sample, efficient and research quality are studied in influence; 2) special occasions that is difficult to realize in upper support, in the traditional liberation of hydrogen method of testing as the magnesium alloy biodegradability, the application of " suspension type " load sample method is restricted; When 3) in fluid media (medium), carrying out material properties test, as utilize software such as silk/line to adopt " suspension type " mode to hang sample, then the position of sample is subjected to the double influence of self gravitation effect and velocity of medium and " fluid ", test result is produced complicated influence, be unfavorable for the parsing of data and the exploration of related law.
Summary of the invention
The purpose of this utility model is the deficiency at prior art, and the upper load sampler of a kind of simple for structure, easy to use, dependable performance, highly versatile is provided, promptly can be from the test specimen upper end to its load sample device that loads.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of upper load sampler, comprise a function axle, three above load sample heads and with the bridge that is connected of a load sample equal number, an end that wherein is connected bridge links to each other with the lower end of function axle, the other end links to each other with the upper end of load sample head, the lower end of the upper end of function axle and load sample head is free end, and described load sample head is an one-to-one relationship with being connected between the bridge; Described function axle and load sample head are right cylinder; The axis of the axis of described load sample head and function axle is parallel to each other.
Described linking bridge is measure-alike straight-bar, and to be connected bridge be that datum line spatially evenly distributes with the axis of function axle.
Described load sample area of bed is identical, and its free end is equipped with the external thread that is used to install sample.
Compared with prior art, the utlity model has following outstanding effect:
1) can realize test specimen fix from sample upper end with hard material and is supported, thus the difficult problem that traditional " suspension type " load sample method of solution runs into.
2) design that is threaded between load sample head and specimen sample, the loading that can guarantee sample firmly, reliable, the regulation and control for the sample pose simultaneously provide convenience.
3) one drag three or above structural design, can realize disposable loading and follow-up study test to a plurality of samples, obtain multi-group data by single test, when significantly reducing workload, significantly improving efficiency of research and development, guarantee the controllability and the collimation of test condition, be particularly suitable in the cylindrical shape test container or in the simulation test that rotatablely moves to the loading of a plurality of parallel samples.

Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further, but enforcement of the present utility model and protection domain are not limited thereto.
As shown in Figure 1 and Figure 2, the upper load sampler that relates to of the utility model by a function axle 1, three above load samples 2 and with load sample 2 equal number be connected bridge 3 totally three parts form.An end that wherein is connected bridge 3 links to each other with the lower end of function axle 1, and the upper end of the other end and load sample 2 links to each other, and load sample 2 is one-to-one relationship with being connected between the bridge 3.Function axle 1 and load sample 2 is right cylinder.The axis of load sample 2 and the axis of function axle 1 are parallel to each other.Load sample 2 is measure-alike, and its free end is equipped with the external thread that is used to install sample.Being connected bridge 3 be measure-alike straight-bar, and to be connected bridge 3 be datum line evenly distribution spatially with the axis of function axle 1.
As shown in Figure 3, Figure 4, be enforcement synoptic diagram of the present utility model, implementation step is as follows: at first the sample 4 that is processed with the internal thread hole that mates with load sample 2 external thread is carried out pre-treatments such as metallographic polishing, cleaning, drying, the differential of the arc/anodic oxidation, chemical conversion, bionical passivation, electroless plating, afterwards sample is screwed in load sample 2, promptly realized easily test specimen fix from sample upper end with hard material and is supported, thereby solved the difficult problem that traditional " suspension type " load sample method runs into.The design that is threaded between load sample 2 and the specimen sample 4, the loading that can guarantee sample firmly, reliable, the regulation and control for the sample pose simultaneously provide convenience.Benefit from the structural design of overloading sample head, during practical application the utility model, according to research/teaching needs, but a specimen of disposable loading (as shown in Figure 3) or a plurality of specimen (being illustrated in figure 4 as the situation of loading three samples simultaneously), be convenient to obtain multi-group data by single test, when significantly reducing workload, significantly improving efficiency of research and development, guarantee the controllability and the collimation of test condition.After finishing the loading of sample, again down with load sampler load sample 2, free end by load sampler function axle 1 vertically is fixed in assigned address in the test container with load sampler, can carry out subsequent operation according to known research/teaching operation step subsequently, as processing of film forming such as the differential of the arc/anodic oxidation, chemical conversion, bionical passivation, electroless plating or the test of corrosion degradation property etc.When reality was used, the free end of described function axle 1 can be according to practical situations, and processing through hole, screw thread etc. are to satisfy the exact functionality additional requirement.Fixing and installing a plurality of parallel samples when the utility model is particularly suitable for rotatablely moving simulation test.
