Description
Technical Field
The invention designs a soaking experiment tool for a plastic retainer.
Background
Plastic holders often come into contact with various liquid chemicals during use, which requires good compatibility between the plastic holder and the various liquid chemicals. When the plastic retainer contacts with the liquid chemical reagent, the quality, the size, the appearance, the mechanical property and the like of the plastic retainer can be changed, and the liquid chemical reagent resistance of the plastic retainer can be known through comparing and analyzing various indexes of the sample before and after soaking.
At present, in the plastic holder soaking test process, a tester generally suspends and then soaks a sample, the method is difficult to ensure the stability of the sample in liquid, excessive contact is easily caused between the sample and the sample, and between the sample and a container, and the experimental result is easily influenced, so that the tester is often required to frequently perform manual interference, the contact of the sample in the liquid is reduced as much as possible, and the sample is kept independent. In addition, because some plastic holders have low density, in order to completely soak the sample in the test solution, a weight needs to be tied on the sample, so that the sample is easy to deform under stress, the operation is complex and time-consuming, and the experimental result is easy to be inaccurate.

By adopting the scheme, the specific operation mode is as follows: firstly, a chassis is horizontally placed on a desktop, then a support frame is sleeved on a support shaft, then a sample needing to be soaked is placed on the support frame along the support shaft, then a sample frame is sleeved on the support shaft, the sample is enabled to be positioned between the support frame and the sample frame under the action of a first gear lever and a second gear lever, then the sample is continuously placed on the first sample frame along the support shaft, a second sample frame is continuously sleeved on the support shaft, the sample frame at two axial ends of the sample can be positioned between the sample frame and the sample frame under the limitation of the sample frame, the operation is repeated, the completed tool is placed in a beaker after the sample frame cannot be continuously sleeved on the support shaft, the chassis is enabled to be positioned at the bottom of the beaker, a plurality of samples hung on the support shaft are all positioned in the beaker, and at the moment, only a test solution needs to be injected into the beaker. Experiment is carried out through this frock, simple structure not only, and convenient operation can effectively keep apart the contact between sample and the sample, also can reduce the contact between sample and the beaker wall to a certain extent, can be through simple human interference when appropriate for sample and beaker wall contactless provides convenience for the experiment, also provides the assurance for experimental data.
As a further configuration of the present invention, the first shift lever and the second shift lever have a circular cross section.
Adopt above-mentioned scheme, when the cross-section of first shelves pole and second shelves pole is circular, the contact between sample and first shelves pole or the second shelves pole of arranging in wherein all is line contact, can further reduce the contact of sample and first shelves pole or second shelves pole, is favorable to improving the accuracy of experimental result.
According to the further arrangement of the invention, the space between the support frame and the sample frame or the space between the sample frame and the sample frame is respectively separated through the isolation sleeve, two ends of the isolation sleeve are respectively abutted against the sample frame or the support frame at two axial ends, and the isolation sleeve is in threaded connection with the support shaft.
By adopting the scheme, the distance between the support frame and the sample frame or between the sample frame and the sample frame is isolated by using the isolating sleeve, so that the aim of controlling the distance between the support frame and the sample frame or between the sample frame and the sample frame can be achieved, and the distance between the support frame and the sample frame or between the sample frame and the sample frame is the same as the height of the isolating sleeve.
As a further arrangement of the invention, a pressing rod for pressing against the sample is slidably arranged on the second blocking rod of the sample holder along the axial direction of the second blocking rod, and an elastic pressing block with a bullet-shaped head is arranged at the end part of the pressing rod.
Adopt above-mentioned scheme, support through supporting the depression bar and press on the sample, can further reduce the area of contact of second shelves pole and sample, be the point contact between the tip of support depression bar and the sample, when having guaranteed to form limiting displacement to the sample like this, can reduce the contact rather than as far as, set up elasticity suppression piece at the tip of support depression bar simultaneously and can prevent that the sample atress warp, avoid influencing the experimental result.
As a further arrangement of the present invention, a limiting member for limiting the axial upward sliding of the sample holder is screwed to the supporting shaft.
Adopt above-mentioned scheme, through locating part and back shaft threaded connection, can play limiting displacement to the sample frame, prevent sample frame rebound, the sample frame can move under the locating part knob to with the sample spacing position slightly can, the briquetting is just in time contradicted with the sample this moment, can guarantee that the sample is spacing between support frame and sample frame or between sample frame and sample frame, not only simple structure, it is also very convenient to operate.
As a further arrangement of the invention, the top end of the supporting shaft is detachably connected with a handle which is convenient to take.
Adopt above-mentioned scheme, the handle can be convenient for the sample and soak the completion back, takes out its whole beaker from, avoids the direct and liquid chemical reagent contact of health, improves experiment operation security.
The invention is further described below with reference to the accompanying drawings.
