The utility model adds a test tube plug to the glass test tube, so that the glass test tube can be made into a sealed container, which is convenient for the test tube to store experimental or inspection supplies, expands the use of the glass test tube, and brings convenience to laboratories and test rooms.
[0004] However, the utility model still has some shortcomings. For example, the device is sealed by a test tube plug, but when the test tube plug is pulled out from the sampling test tube, it is easy to cause the hazardous chemical test sample to splash on the hands of the staff due to excessive force, causing damage to the staff's hands and making it inconvenient to use. In addition, when the sampling test tube containing the hazardous chemical test sample accidentally falls to the ground, it cannot effectively cushion the impact force when it falls to the ground, and it is easy to break due to the impact force when it falls to the ground, causing hazardous chemicals to splash, posing a great safety hazard.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-4 As shown, a portable sampling test tube for laboratory use comprises an armored protective cover 1, a protective mechanism 2 is arranged on the inner side of the armored protective cover 1, a cover opening mechanism 3 is arranged on the upper side of the protective mechanism 2, the cover opening mechanism 3 comprises a cover body 31 movably arranged on the upper end of the protective mechanism 2, a push rod 32 is movably arranged on the inner side of the cover body 31, a pressing block 33 is fixedly connected to the upper end of the push rod 32, a top block 34 is fixedly arranged on the lower end of the push rod 32, a reset spring 35 is fixedly connected between the lower end of the armored protective cover 1 and the upper end of the top block 34, a silicone cover 36 is fixedly connected to the lower end of the armored protective cover 1, a fixing ring 37 is fixedly arranged on the lower end of the silicone cover 36, a plurality of groups of anti-sliding blocks 38 are fixedly connected to the outer side of the fixing ring 37, a pull ring 39 is fixedly arranged on the upper end of the armored protective cover 1 near the outer side, and a pull rope 310 is movably sleeved on one side of the pull ring 39.
[0023] In this embodiment, the push rod 32 passes through the inner side of the cover body 31 near the center and is connected to the pressing block 33. The upper side of the top block 34 near the outer side is set as an inclined surface. The top block 34 is adapted to the fixing ring 37. The reset spring 35 is movably sleeved on the outer side of the push rod 32. The silicone sleeve 36, the fixing ring 37, and the anti-sliding block 38 are an integrated structure. The silicone sleeve 36 and the fixing ring 37 cover the outer side of the reset spring 35. The fixing ring 37 and several groups of anti-sliding blocks 38 are made of heat-resistant silicone material, and several groups of anti-sliding blocks 38 are arranged in a circle.
[0024] The push rod 32 and the top block 34 are reset according to the elastic action of the reset spring 35, and then the top block 34 supports the inner side of the fixing ring 37 and the anti-sliding block 38, thereby increasing the direct pressure between the fixing ring 37 and the test tube body 21, thereby facilitating the sealing and opening of the test tube body 21, preventing the dangerous chemical test sample from splashing on the hands of the staff due to excessive force, thereby reducing the damage to the hands of the staff and facilitating use. In addition, the setting of the pull rope 310 facilitates the convenient storage and use of multiple groups of test tube bodies 21, thereby improving convenience.
[0025] In this embodiment, the protective mechanism 2 includes a test tube body 21 fixedly arranged on the inner side of the armored protective cover 1, and a plurality of buffer blocks 22 are directly fixedly arranged on the armored protective cover 1 and the test tube body 21. Five groups of buffer springs 23 are fixedly connected between the armored protective cover 1 and the test tube body 21 near the bottom. The upper end of the test tube body 21 is movably covered with a cover body 31, and a limiting ring is fixedly arranged on the inner side of the test tube body 21 near the lower side of the fixing ring 37. The plurality of buffer blocks 22 are evenly arranged, and the buffer blocks 22 are made of elastic silicone material.
[0026] Specifically, when the test tube body 21 accidentally falls, the armored protective cover 1 first contacts the ground, and the first step of impact force unloading and buffering is performed on the test tube body 21 to prevent it from directly contacting the ground. Through the joint elastic action of several groups of buffer blocks 22 and five groups of buffer springs 23 fixed at the bottom, the test tube body 21 is further elastically buffered to achieve multi-angle protection without dead ends, preventing the test tube body 21 from being broken due to excessive impact force when falling to the ground, thereby avoiding the splashing of dangerous chemicals and improving safety.
[0027] Working principle:
[0028] During use, when the test tube body 21 accidentally falls, the armored protective cover 1 first contacts the ground, and the first step of impact force unloading and buffering is performed on the test tube body 21 to prevent it from directly contacting the ground. The test tube body 21 is further elastically buffered by the elastic action of several groups of buffer blocks 22 and five groups of buffer springs 23 fixedly arranged at the bottom, so as to achieve multi-angle and no-dead-angle protection, and prevent the test tube body 21 from being broken due to excessive impact force when falling on the ground, thereby avoiding the splashing of dangerous chemicals and improving safety. In addition, by pressing the pressing block 33, the push rod 32 drives the top block 34 to move downward, and at the same time the top block 34 stretches the reset spring 35, and the top block 34 moves to the fixing ring 37. When the cover 31 is removed, the push rod 32 and the top block 34 are reset by loosening the pressing block 33 and the elastic action of the reset spring 35, so that the top block 34 supports the inner side of the fixing ring 37 and the anti-sliding block 38, thereby increasing the direct pressure between the fixing ring 37 and the test tube body 21, making it convenient to cover and open the test tube body 21, and preventing the dangerous chemical test samples from splashing on the hands of the staff due to excessive force, thereby reducing the damage to the hands of the staff and facilitating use. In addition, the setting of the pull rope 310 facilitates the convenient storage and use of multiple groups of test tube bodies 21, thereby improving convenience.
