Description

Buffering protection pad for centrifugal machine

Technical Field

The utility model belongs to centrifuge, concretely relates to centrifuge buffering protection pad.

Background

The centrifugal machine is an instrument which accelerates the sedimentation speed of particles in liquid by utilizing the strong centrifugal force generated by the high-speed rotation of a rotor and separates substances with different sedimentation coefficients and buoyancy densities in a sample, and is widely applied to the fields of life science, medicine, chemistry, environmental protection and the like.

Centrifuge rotors are a key component of centrifuges. When the centrifuge works normally, strong centrifugal force can be generated due to high-speed rotation of the rotor, so that loads (test tubes) in the rotor can bear huge centrifugal force. Because the bottom of a common test tube is hemispherical, the bottom of the test tube is easy to break during centrifugation, thereby causing the liquid in the test tube to flow out and the detection experiment to fail.

The current scheme for solving the problem is two: the first scheme is that a flat pad made of rubber materials is arranged at the bottom of a test tube, has a certain buffering effect, and can only meet the requirement of low-speed centrifugation. Once the rotating speed is slightly higher, the test tube is easy to break, and meanwhile, the flat pad is easy to slide, so that the normal use of the test tube can be ensured only by frequent arrangement; scheme two is wrapped up the test tube bottom according to the gasket of rubber materials of the size preparation of test tube bottom, this kind of mode effect is better, when high-speed centrifugation, the test tube is also difficult to break, but because the test tube size of the customer use of difference differs, the bottom shape is also different, just must customize the rubber pad according to every test tube shape, the great variety of use that can cause the user simultaneously is inconvenient, or be equipped with wrong gasket and can cause man-machine injury, and one set of grinding apparatus of cushion needs customization of each kind of size, lead to with high costs.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a adaptability is good, can effectively protect the centrifuge buffering protection pad of test tube.

Realize the utility model discloses the technical scheme of purpose is:

the utility model provides a centrifuge buffering protection pad, which comprises a body, the back of body is equipped with a plurality of evenly distributed's the pit as the buffering space that corresponds bottom the test tube.

The front surface of the body is provided with a plurality of positioning support columns which are uniformly distributed and are arranged around the concave pits correspondingly.

The utility model has the advantages that:

1. the utility model discloses the pit as buffer space that has elastic deformation can effectual absorption impact energy protection test tube bottom, avoids bounce-back liquid simultaneously to hit (its buffering principle is similar with fire control air cushion or trampoline). Simultaneously the body can wrap up whole test tube bottom until moving to the pit bottom at the buffering deformation layer of pit department, and the test tube just is difficult to break just so to the even atress in whole test tube bottom.

2. The utility model discloses can effectively reduce because of the different problem that causes the gasket kind of test tube, can realize that a blotter satisfies the use of the multiple test tube in certain size range, the effectual kind that reduces the blotter reduces the mould cost.

3. The locate function of location support column effectively reduces the arrangement work of user before centrifugation at every turn, also need not often to change the gasket simultaneously, reduces operating personnel's work load. The positioning support column also serves to even the pressure of the entire adapter against the bottom.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Detailed Description

See fig. 1 and 2, the utility model provides a centrifuge buffering protection pad 1, including body 101, the back of body 101 is equipped with a plurality of evenly distributed's pit 103 that corresponds with the test tube bottom, the front of body 101 be equipped with a plurality of evenly distributed establish with the positioning support post 102 that corresponds around the pit 103.

The utility model discloses an use

After the body 101 of the centrifuge buffer protection pad 1 is placed at the bottom of the adapter holder 5, the adapter 2 is assembled on the adapter holder 5, and the positioning support column 102 is abutted against and supports the adapter 2, at this time, the concave pit 103 is aligned with the test tube hole on the adapter 2, and the part of the body 101 is the buffer deformation layer 104.

When adapter 2 is fully inserted with vacuum blood collection tube 4, the bottom of the tube is suspended for a distance of 5-7mm, as shown in FIG. 3. The whole centrifuge that puts into of adapter 2 begins high-speed rotation, until when its centrifugal force is greater than vacuum blood collection tube 4 self and vacuum blood collection tube cap 3's bonding strength, vacuum blood collection tube 4 separates with vacuum blood collection tube cap 3, vacuum blood collection tube 4 down strikes buffering deformation layer 104 on centrifuge buffering protection pad 1's the body 101 with certain speed, thereby produce elastic deformation and slow down vacuum blood collection tube 4 down impact force, until buffering motion space 104 is contacted by the bottom surface of complete extrusion with adapter support 5, as shown in fig. 4, 5. When the centrifugation is finished, the buffer deformation layer 104 gradually recovers along with the reduction of the centrifuge rotating speed and the reduction of the centrifugal force, and the vacuum blood collection tube 4 is slowly bounced to finish the buffer protection.

When the test tube is separated with the pipe cap when the test tube down strikes with certain speed, because the utility model discloses the buffer space that has elastic deformation can effectual absorption impact energy protect the test tube, avoids bounce-back liquid to hit simultaneously (its buffering principle is similar with fire control air cushion or trampoline).

Claims (2)

1. The utility model provides a centrifuge buffering protection pad, characterized by includes the body, the back of body is equipped with a plurality of evenly distributed and test tube bottom correspond as the pit in buffering space.

2. The cushion of claim 1, wherein the front surface of the body has a plurality of positioning support columns uniformly distributed around the concave pits.
