Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge tubes, and particularly relates to a centrifuge tube for preventing spillage. Background Art

[0002] A centrifuge tube is a commonly used tubular container in laboratories, mainly used for containing samples, and different components in the samples are separated by the high-speed rotation of a centrifuge. The design and material selection of centrifuge tubes are both aimed at meeting specific experimental requirements to ensure the accuracy and reliability of experimental results.

[0003] For example, a Chinese patent with the publication number CN209974770U discloses a new type of cell centrifuge tube, which includes a centrifuge tube body. There is a centrifuge tube opening at the top of the centrifuge tube body, and a sealing rubber plug is arranged outside the centrifuge tube opening. A polypropylene tube is arranged outside the accommodating cavity. There is a centrifuge tube base at the bottom of the scale marking line, and a reinforcing bottom ring is arranged at the bottom of the centrifuge tube base. Anti-slip ridges are arranged on the outside of the centrifuge tube body; the centrifuge tube cap is fixedly connected to the centrifuge tube body through a bent connecting belt. The side sealing plunger is connected to the outside of the centrifuge tube cap through an adhesive. The annular groove is connected to the bottom of the centrifuge tube cap through an adhesive. The fixing block is fixedly arranged inside the centrifuge tube cap through an adhesive; the bent connecting belt is fixedly connected to the centrifuge tube body through an adhesive block. The bent curved belt is fixed at the center of the bent connecting belt through a connecting buckle. The reinforcing rib is connected and fixed to the bottom of the bent curved belt through an adhesive.

[0004] The above-mentioned cell centrifuge tube solves the problem of the firmness of the bent connecting belt of the existing centrifuge tube cover. However, there are still some defects in the existing centrifuge tubes that need to be improved. Traditional centrifuge tubes often lack sufficient stability when directly placed, and are prone to tipping due to slight touch or environmental vibration, which undoubtedly increases the risk of accidental outflow of the sample liquid, not only may pollute the experimental environment, but also may cause the loss of valuable samples. In addition, the commonly used socket connection method between the existing centrifuge tube and the tube sleeve, although simple and easy to implement, shows insufficient reliability of the connection in the face of high-intensity centrifugal action or after long-term use and wear.

Detailed implementation manners

[0020] Embodiment

[0021] Referring to Figures 1 to 4 In this embodiment, a spill-proof centrifuge tube includes a centrifuge tube body 1. A tube sleeve 5 is sleeved on one side of the centrifuge tube body 1. One end of the tube sleeve 5 is fixedly connected to a supporting ball seat 2. A placement groove 3 is formed inside the supporting ball seat 2. A counterweight 4 is installed inside the placement groove 3. A positioning mechanism 12 is provided between the tube sleeve 5 and the centrifuge tube body 1. The positioning mechanism 12 includes a mounting block 121. The mounting block 121 is fixedly connected to the outer wall of the centrifuge tube body 1. A positioning hole 122 is formed inside the mounting block 121. A positioning rod 123 is inserted into the positioning hole 122. The top end of the positioning rod 123 is fixedly connected to the bottom end of the tube sleeve 5. A clamping hole 124 is formed inside the positioning rod 123. A clamping component 125 is provided on one side of the mounting block 121; Through the above settings, not only the problem that the centrifuge tube may be toppled due to slight touch or environmental vibration, which increases the risk of accidental outflow of the sample liquid, is solved, but also the problem that the commonly used socket connection method between the existing centrifuge tube and the tube sleeve 5 has insufficient connection reliability is solved.

[0022] Referring to Figure 4, the snap - fit component 125 includes an installation groove 1254. The installation groove 1254 is opened inside the installation block 121. A snap - block 1251 is slidably connected inside the installation groove 1254. The snap - block 1251 is movably connected to the snap - hole 124. One side of the snap - block 1251 is an arc - shaped structure. One end of the snap - block 1251 is fixedly connected to a slider 1252. A spring 1253 is fixedly connected between the slider 1252 and the installation groove 1254. By setting the snap - fit component 125, when the positioning rod 123 is inserted into the positioning hole 122 of the installation block 121, the arc - shaped snap - block 1251 is pushed. Since the snap - block 1251 is connected to the spring 1253, it contracts into the installation groove 1254 under the action of the spring 1253. When the positioning rod 123 is inserted to the maximum distance, the snap - block 1251 is fixed to the snap - hole 124 through the spring 1253, making the connection between the tube sleeve 5 and the centrifuge tube body 1 more reliable and not easily falling off. On the contrary, when it is necessary to remove the tube sleeve 5, only an upward force needs to be applied to separate the tube sleeve 5 from the centrifuge tube body 1.

[0023] Reference Figure 2 , a support ball seat 2 is fixedly connected with support bent rods 6 on the outside, and there are six support bent rods 6 in total. One end of the support bent rod 6 is fixedly connected with a ball block 7. By fixing a plurality of support bent rods 6 on the support ball seat 2, the support bent rods 6 incline downward, and the ball block 7 is fixed on the support bent rod 6. When the inclination angle of the support ball seat 2 is relatively large, the support ball seat 2 can be supported under the action of the support bent rods 6 and the ball block 7, preventing the support ball seat 2 from lying flat and causing the centrifuge tube body 1 to incline, and improving the stability of the placement of the centrifuge tube body 1.

[0024] Reference Figures 2 - 3 , a docking groove 8 is opened inside the support ball seat 2. One end of the centrifuge tube body 1 is fixedly connected with a docking block 9. The docking block 9 is movably connected to the docking groove 8. By opening the docking groove 8 inside the support ball seat 2, a sealing ring is fixed in the docking groove 8, and the docking block 9 is fixed on the centrifuge tube body 1. Using the connection between the docking block 9 and the docking groove 8, the connection between the centrifuge tube body 1 and the support ball seat 2 is better, preventing liquid from flowing out.

[0025] Reference Figure 3 , a rubber column 10 is fixedly connected inside the tube sleeve 5 where the support ball seat 2 is located. The rubber column 10 is movably connected to the centrifuge tube body 1. One end of the rubber column 10 is fixedly connected with a rubber disc 11, and the rubber disc 11 is also movably connected to the centrifuge tube body 1. By setting the rubber column 10 and the rubber disc 11, when the liquid in the centrifuge tube body 1 shakes and impacts upward, buffering is carried out using the characteristics of the rubber disc 11 and the rubber column 10, avoiding directly impacting the tube sleeve 5 and causing unstable installation. Moreover, the rubber disc 11 can prevent the liquid in the centrifuge tube body 1 from flowing out and prevent the liquid from spilling.

[0026] Principle of use and advantages: When the centrifuge tube body 1 is placed, place the bottom of the supporting ball seat 2 on the experimental platform. When the centrifuge tube body 1 is collided by an external object, the center of gravity of the supporting ball seat 2 is stably supported under the action of the counterweight 4, preventing the centrifuge tube body 1 from tipping over and causing the liquid in the centrifuge tube body 1 to accidentally flow out, thereby avoiding environmental pollution and loss of valuable samples. When the liquid in the centrifuge tube body 1 sloshes upward and impacts, the characteristics of the rubber disc 11 and the rubber column 10 are used for buffering to avoid directly impacting the tube sleeve 5 and causing unstable installation. Moreover, the rubber disc 11 can prevent the liquid in the centrifuge tube body 1 from flowing out and prevent the liquid from spilling. Since the positioning rod 123 is installed on the tube sleeve 5 and the fixed mounting block 121 is installed on the centrifuge tube body 1, the positioning rod 123 is inserted into the positioning hole 122 in the mounting block 121, and the clamping block 1251 is fixed to the clamping hole 124 under the action of the spring 1253, so that the positioning rod 123 is fixedly connected to the mounting block 121, making the tube sleeve 5 not easy to fall off and ensuring that the liquid in the centrifuge tube body 1 will not flow out. When it is necessary to remove the tube sleeve 5, only need to move the supporting ball seat 2 upward, so that the positioning rod 123 forces the clamping block 1251, and the clamping block 1251 leaves the clamping hole 124 under the action of the spring 1253. At this time, the tube sleeve 5 can be removed from the centrifuge tube body 1, and then the centrifuge tube body 1 can be used.
