Description

Technical Field

[0001] The utility model relates to an experimental tool, in particular to a special tool for EP tubes. Background Art

[0002] An experiment usually requires the use of multiple EP tubes. When using multiple EP tubes for an experiment, you need to avoid cross contamination during the operation when opening the EP tubes. In particular, you need to be very careful when opening the EP tubes. If you are not careful, your gloves will touch the inside of the EP tube caps, causing cross contamination of samples in multiple EP tubes.

[0003] During the experiment, it is necessary to observe whether the gloves are touching the inner wall of the EP tube at any time during the opening process, and to change gloves at any time. If necessary, it is even necessary to repeat the experiment from the beginning, which reduces the experimental efficiency and increases the consumption of consumables. At the same time, on the other hand, when the experiment volume is large, it is easy to cause finger pain because the same finger, such as the thumb, is always used to open the cover. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a special tool for EP pipes, which can realize the opening and closing operation of the pipe cover of the EP pipe and the removal operation of the inner pipe, and avoid direct contact of human hands with the EP pipe.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a special tool for EP pipes, including a connecting part, a V-shaped part arranged at one end of the connecting part and a pulling part arranged at the other end of the connecting part, the V-shaped part includes two fork arms arranged symmetrically on the left and right, a V-shaped groove is formed between the two fork arms, and a long through hole is provided on the pulling part. Principle of the utility model: when it is necessary to open the tube cover of the EP tube, fingers pinch the connecting part and the lifting part, place the first fork arm under the buckle part protruding on one side of the tube cover, place the second fork arm on the top of the tube cover, rotate the first fork arm with the second fork arm as the rotation axis, and the first fork arm acts on the tube cover to open it; the second way to open the tube cover is to pinch the connecting part and the V-shaped part with fingers, insert the elongated hole on the lifting part into the buckle part protruding on one side of the tube cover, and pull up with force to open the tube cover; when it is necessary to close the tube cover, fingers pinch the connecting part and the lifting part, place the first fork arm on one side of the outer tube, place the second fork arm on the top of the tube cover, rotate the second fork arm with the first fork arm as the rotation axis, and the second fork arm acts on the tube cover to close it; when it is necessary to take the inner tube out of the outer tube, fingers pinch the connecting part and the lifting part, place the two fork arms on both sides of the inner tube, and lift the inner tube through the annular boss on the outer wall of the inner tube. It can realize the opening and closing operation of the EP tube cover and the removal operation of the inner tube, avoiding direct contact of human hands with the EP tube and avoiding cross contamination.

[0006] As an improvement, the connecting portion, the V-shaped portion and the lifting portion are punched and formed in one piece, and the connecting portion, the V-shaped portion and the lifting portion have the same thickness.

[0007] As an improvement, the lifting portion is oval in shape.

[0008] As an improvement, the angle between the two fork arms is 30-60°, and the length of the fork arms is 15-25 mm.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The tube cover can be opened and closed by placing the two fork arms in different positions, the tube cover can be opened by the long perforation on the lifting part, and the inner tube can be lifted and taken out by the two fork arms, thereby preventing direct contact of human hands with the EP tube and avoiding cross contamination.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] A special tool for EP pipes, such as Figure 2 , 3 As shown, the EP pipe targeted by the utility model is a mixed pipe, which includes an outer tube 6, an inner tube 5 and a tube cover 4; the tube cover 4 includes a cover plate 42 and a round tube 43 arranged at the bottom of the cover plate 42, the round tube 43 cooperates with the tube mouth of the inner tube 5, the cover plate 42 is connected to the outer tube 6 through a connecting belt 7, the cover plate 42 includes a circular portion and a protruding buckle portion 41 arranged on one side of the circular portion, and the tube cover 4 is usually opened and closed by the buckle portion 41; the outer wall of the inner tube 5 is provided with an annular flange 51, and the annular flange 51 is abutted against the upper end of the outer tube 6, so that the lower part of the inner tube 5 is inserted into the outer tube 6, and the upper part of the inner tube 5 extends out of the outer tube 6. Figure 1As shown, the EP pipe special tool includes a connecting part 1, a V-shaped part arranged at one end of the connecting part 1, and a lifting part 2 arranged at the other end of the connecting part 1; the connecting part 1, the V-shaped part and the lifting part 2 are punched and formed by sheet metal, and the thickness of the connecting part 1, the V-shaped part and the lifting part 2 are the same, all of which are 1-2mm, and the overall structure is light and small; the V-shaped part includes two fork arms 3 arranged symmetrically on the left and right, a V-shaped groove is formed between the two fork arms 3, the angle between the two fork arms 3 is 30~60°, the length of the fork arms 3 is 15~25mm, and the size can be set according to the size of the EP.
