Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a test tube, the utility model provides a technical problem can avoid the test tube lid to pop out.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a test tube, includes test tube body and test tube lid, the test tube lid includes the lid and fixes the bottle plug in the lid, its characterized in that, the perisporium of bottle plug is face of cylinder and the perisporium of bottle plug can paste with the inner wall that is located this mouth of pipe department of test tube and paste sealedly, the exhaust duct has been seted up along the axial on the perisporium of bottle plug, the one end of exhaust duct runs through the front end of bottle plug for lining up the end, the other end of exhaust duct extends to the middle part of bottle plug and is the blind end.

When the test tube cap is covered on the test tube body, the bottom of the bottle plug is firstly plugged into the tube opening of the test tube body, the peripheral wall of the bottle plug is sealed and attached to the inner wall of the test tube body at the moment, along with the continuous plugging of the bottle plug, the air in the test tube body can be extruded, the redundant air can be discharged through the exhaust groove through the through end of the exhaust groove, when the bottle plug moves to the closed end of the exhaust groove to enter the tube opening of the test tube body, the exhaust groove is sealed at the moment, namely the bottle plug completely seals the tube opening of the test tube body, finally, the rear end of the bottle plug is also plugged into the tube opening of the test tube body, and the operation of the; can fill in test tube body through the air discharge duct when the test tube body is filled in to the bottle plug to reduce and cover this internal atmospheric pressure of test tube behind the test tube lid, avoid appearing because of the too big roughly test tube cap of atmospheric pressure is by the condition of popping out, the volume of exhaust air is equivalent to on the bottle plug with the volume that air discharge duct length matches.

In the test tube, the length of the vent groove is not more than half of the length of the bottle stopper, and the length of the vent groove is not less than one third of the length of the bottle stopper. The structure ensures that the exhaust groove can exhaust enough air and simultaneously ensures that the bottle stopper has enough length to seal the pipe orifice.

In the test tube, the middle part in the cover body is provided with a raised cylindrical lug, and the bottle stopper is sleeved on the cylindrical lug and is integrally formed with the cylindrical lug. The cover body is made of plastic, the bottle stopper is made of rubber, and the bottle stopper is directly formed on the cylindrical convex block of the cover body during processing; bottle plug and lid structure as an organic whole avoids appearing the lid when uncapping and takes off the condition that the back bottle plug still blockked in test tube body.

In the test tube, the outer edge of the rear end of the bottle stopper is provided with a convex abutting convex ring, and the abutting convex ring abuts against the inner bottom surface of the cover body. Support to lean on the bulge loop to support at the mouth of pipe border of test tube body behind the test tube body is filled in completely to the bottle plug, strengthen the leakproofness.

In foretell test tube, the middle part of test tube body is equipped with the partition portion, the partition portion separates into stock solution section and support section with test tube body, the mouth of pipe of stock solution section is covered to the test tube lid. The test tube rack for placing the test tubes is standard, the length of each test tube is matched with the test tube rack, so that the test tube body can be stably placed on the test tube rack, when a small amount of liquid is stored in the existing standard test tube and needs to be extracted, the needle tube needs to be inserted into the bottom of the test tube, and the insertion distance of the needle tube is large, so that the operation is unchanged; the length of the test tube body is standard length, the partition part is arranged in the middle of the test tube body, the depth of the liquid storage section can be reduced, the liquid storage section is smaller relative to the depth of the existing test tube aiming at the extraction of a small amount of liquid, namely, the liquid can be extracted by inserting the needle tube into a shallow distance, the operation is more convenient, and the efficiency is improved; the support section guarantees that the test tube can normally be placed on the test-tube rack of standard.

In the above test tube, the partition is funnel-shaped, and an opening of the partition faces the liquid storage section. The partition part of the structure is convenient for gathering liquid and extracting the liquid.

In the test tube, the bottom of the partition part is also extended with a counterweight strip positioned in the support section, and the counterweight strip is coaxial with the test tube body. The balance weight strip makes the focus of test tube reduce, and the stability of the test tube of being convenient for is placed.

In the test tube, the end of the support section is an open nozzle, and the end face of the support section where the nozzle is located is perpendicular to the axis of the test tube body. When not placing on the test-tube rack, can be with the vertical direct placement of test tube body on the desktop through above-mentioned structure.

In the test tube, the tube opening of the support section is detachably connected with a tube bottom cap, and the cap head of the tube bottom cap is a dome. When the operation test tube, adorn the tube bottom block to test tube body on, the calotte of tube bottom block supports in palm department of the hand, promotes operation comfort level.

Compared with the prior art, the test tube has the advantages that the phenomenon that the test tube cover pops up is avoided through the exhaust of the exhaust groove, and the test tube cover can be conveniently drawn.
