Description

Technical Field

[0001] The present application relates to the technical field of centrifuge protection, and in particular to a desktop low-speed centrifuge protection mechanism. Background Art

[0002] The centrifuge is composed of a body, a motor, a rotor shaft, an angle rotor, a sample tube and a control system. It is used to separate solid particles or liquid components in a suspended liquid according to density differences. It is a common laboratory equipment.

[0003] In the prior art, the angular rotor is generally placed directly on the rotor shaft and then centrifuged. However, in this operation, the angular rotor is easily disturbed by the outside world and is easily touched by people by mistake, which can easily lead to accidents.

[0004] In order to solve the problem of being easily disturbed by the outside world during the centrifugation process, the prior art uses a centrifuge closed cover to ensure safety, but the operation is not convenient enough and the cover needs to be opened frequently to check the sample.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a desktop low-speed centrifuge protection mechanism, including a body, a turntable is arranged inside the body, a rotor shaft is fixedly connected to the upper surface of the turntable, a thread is provided on the upper end of the rotor shaft, an angular rotor is slidably connected to the arc surface of the rotor shaft, one end of the body is electrically connected to a control board, one end of the body is provided with a protection device, the protection device includes two limit plates, one end of the two limit plates are fixedly connected to the body, the ends of the two limit plates close to each other are fixedly connected to a rotating shaft, and the arc surface of the rotating shaft rotates An adjusting plate is connected, and one end of the adjusting plate close to the body is fixedly connected to a connecting column, one end of the connecting column is fixedly connected to a round cover, the round cover is made of transparent glass, and the end of the round cover away from the adjusting plate is fixedly connected to a positioning column, the inner wall of the positioning column is threadedly connected to a screw, and two limiting grooves are provided on one side of the body with a control plate, and the two limiting grooves are symmetrically distributed on both sides of the control plate, and the inner wall of the limiting groove is provided with a circular hole, and the inner wall of the limiting groove is slidably connected to a protective cover, and the lower surface of the protective cover is fixedly connected to two fixing blocks, and the fixing blocks are interference-connected with the circular holes.

[0007] The effect achieved by the above components is: when centrifugal operation is needed, we can place the test tube on the angular rotor, then fix the angular rotor on the rotating shaft, and then rotate the round cover, the round cover will move in a circle along the rotating shaft. When the round cover reaches the upper surface of the machine body, rotate the screw until the screw is close to the machine body, and then start the centrifuge through the control panel. After starting, separate the fixed block from the circular hole, and then move the protective cover down along the direction of the limit groove until it completely covers the control panel.

[0008] Preferably, a rubber pad is provided on the lower surface of the screw, and anti-slip grooves are evenly formed on the surface of the rubber pad.

[0009] The effect achieved by the above components is: to provide a certain buffering effect when tightening the screw, thereby reducing the pressure on the machine body and preventing the machine body from being scratched.

[0010] Preferably, a handle is fixedly connected to the upper surface of the round cover, and the cross-section of the handle is U-shaped.

[0011] The effect achieved by the above components is that the operator can more easily open or close the round cover to perform maintenance, cleaning and other operations.

[0012] Preferably, a support block is fixedly connected to the upper surface of the body, and the support block is slidably connected to the round cover.

[0013] The effects achieved by the above components are as follows: the support block is used to provide support and guidance when the round cover is opened or closed.

[0014] Preferably, a storage device is provided on one side of the body, and the storage device includes two positioning plates, one end of the positioning plates is fixedly connected to the body, a sliding groove is provided on the side where the two positioning plates are close to each other, the inner walls of the two sliding grooves are slidably connected with sliders, and a test tube rack is fixedly connected on the side where the two sliders are close to each other.

[0015] The effect achieved by the above components is: in order to provide a safe and stable position for storing test tubes, this design allows the test tube rack to be easily pulled out when needed and can be pushed back to one side of the body when not in use, thereby saving space and ensuring safe storage of the test tube rack.

[0016] Preferably, a support plate is provided below the test tube rack, and one end of the support plate is fixedly connected to the body.

[0017] The effect achieved by the above components is: by adding a support plate under the test tube rack, the structural support of the test tube rack can be effectively increased to prevent the test tube rack from shaking or tilting when storing test tubes or other experimental instruments.

[0018] Preferably, handles are fixedly connected to the upper surfaces of the two sliding blocks, and the handles are made of titanium alloy.

[0019] The effect achieved by the above components is that by adding a handle, the user can more easily pull out or push the test tube rack back into the storage device, and this design can make the operation more convenient and comfortable.

[0020] In summary, the beneficial effects of this application are:

[0021] In the present application, the test tubes are symmetrically placed on the angular rotor, and then the angular rotor is fixed on the rotor shaft, and the handle can be turned, and the handle drives the round cover to rotate. Because the round cover is fixedly connected to the connecting column, the connecting column is fixedly connected to the adjusting plate, and the adjusting plate is rotatably connected on the arc surface of the rotating shaft, the round cover will make a circular motion along the rotating shaft. When the round cover is rotated to the surface of the machine body, the round cover and the support block are tightly fitted. At this time, the screw is rotated, and the screw moves along the positioning column until the screw is tightly attached to the positioning column and fixed to the machine body. At this time, the protective cover is moved, and the protective cover moves along the direction of the limit groove. When the fixed block reaches the position of the circular hole, the fixed block is moved. Fixed block, move the fixed block into the round hole, then set the speed through the console, and then start the centrifuge. After starting, separate the fixed block from the round hole. The protective cover will automatically move down along the limit slot due to gravity. Then the centrifuge will drive the turntable to rotate at high speed, and the rotor shaft on the turntable will rotate with the turntable, and the angular rotor will also rotate at high speed until the centrifugation is completed. During the process, the round cover can be used to observe whether the centrifugation is completed, and the round cover can effectively prevent disturbance during the centrifugation process. Among them, the rubber pad is set to provide a certain buffering effect when tightening the screw, thereby reducing the pressure on the machine body and preventing scratches on the machine body.

[0022] In the present application, before centrifugation begins, the experimenter can place the test tube on the test tube rack, and then align the slider with the slide slot until the slider can no longer slide down. At this time, the test tube rack will also be close to the support plate. When centrifugation starts, the test tube can be removed from the test tube rack and symmetrically placed on the angle rotor. At the end of centrifugation, the test tube is removed from the angle rotor, placed on the test tube rack, and the next batch of test tubes is replaced. The design of the storage device provides a safe and stable position for storing test tubes. This design allows the test tube rack to be easily pulled out when needed, and can be pushed back to one side of the body when not in use, thereby saving space and ensuring the safe storage of the test tube rack. The purpose of the handle is to allow the user to more easily pull out or push the test tube rack back into the storage device. This design can make the operation more convenient and comfortable.

When the round cover 205 reaches the upper surface of the body 1, the screw 207 is rotated until the screw 207 is close to the body 1, and then the centrifuge is started through the control panel 7. After starting, the fixed block 214 is separated from the circular hole 213, and then the protective cover 212 is moved down along the direction of the limit groove 211 until it completely covers the control panel 7. The lower surface of the screw 207 is provided with a rubber pad 208, and the surface of the rubber pad 208 is evenly opened. There are anti-slip grooves. In order to provide a certain buffering effect when tightening the screw 207, thereby reducing the pressure on the body 1 and preventing the body 1 from being scratched, a handle 209 is fixedly connected to the upper surface of the round cover 205. The cross-section of the handle 209 is U-shaped, so that the operator can more easily open or close the round cover 205 for maintenance, cleaning and other operations. A support block 210 is fixedly connected to the upper surface of the body 1. The support block 210 is slidably connected to the round cover 205. The support block 210 is used to provide support and guidance when opening or closing the round cover 205.

[0033] Reference Figure 4 and Figure 5As shown, in this embodiment: the storage device 3 includes two positioning plates 31, one end of the positioning plate 31 is fixedly connected to the body 1, and the two positioning plates 31 are provided with a sliding groove 32 on the side close to each other, and the inner walls of the two sliding grooves 32 are slidably connected with a slider 33, and the two sliders 33 are fixedly connected with a test tube rack 34 on the side close to each other.

A support plate 35 is provided under the test tube rack 34, and one end of the support plate 35 is fixedly connected to the body 1. By adding the support plate 35 under the test tube rack 34, the structural support of the test tube rack 34 can be effectively increased to prevent the test tube rack 34 from shaking or tilting when storing test tubes or other experimental instruments. The upper surfaces of the two sliders 33 are fixedly connected with handles 36, and the material of the handles 36 is titanium alloy.

[0034] Working principle: place the test tube symmetrically on the angle rotor 6, and then fix the angle rotor 6 on the rotor shaft 5, and then turn the handle 209, and the handle 209 drives the round cover 205 to rotate. Because the round cover 205 is fixedly connected to the connecting column 204, the connecting column 204 is fixedly connected to the adjusting plate 203, and the adjusting plate 203 is connected in a rotational connection on the arc surface of the rotating shaft 202, the round cover 205 will make a circular motion along the rotating shaft 202. When the round cover 205 is rotated to the surface of the body 1, the round cover 205 and the support block 210 are tightly fitted. At this time, rotate the screw 207, and the screw 207 moves along the positioning column 206 until the screw 207 is tightly attached to the positioning column 206 and the body 1 to complete the fixation. At this time, move the protective cover 212, and the protective cover 212 moves along the direction of the limiting groove 211 to be fixed. The block 214 reaches the position of the circular hole 213, the fixed block 214 is moved, and the fixed block 214 is moved into the circular hole 213, and then the speed is set through the console, and then the centrifuge is started. After starting, the fixed block 214 is separated from the circular hole 213, and the protective cover 212 will automatically move down along the limit groove 211 due to gravity. Then the centrifuge will drive the turntable 4 to rotate at a high speed, and the rotor shaft 5 on the turntable 4 will rotate with the turntable 4, and the angular rotor 6 will also rotate at a high speed until the centrifugation is completed. During the process, the round cover 205 can be used to observe whether the centrifugation is completed, and the round cover 205 can effectively prevent the centrifugation process from being disturbed. Among them, the rubber pad 208 is provided to provide a certain buffering effect when tightening the screw 207, thereby reducing the pressure on the machine body 1 and preventing the machine body 1 from being scratched.

[0035] Before centrifugation begins, the experimenter can place the test tube on the test tube rack 34, and then align the slider 33 with the slide groove 32 until the slider 33 can no longer slide down. At this time, the test tube rack 34 will also be close to the support plate 35. At the beginning of centrifugation, the test tube can be removed from the test tube rack 34 and symmetrically placed on the angle rotor 6. At the end of centrifugation, the test tube is removed from the angle rotor 6, placed on the test tube rack 34, and a batch of test tubes is replaced. The design of the storage device 3 provides a safe and stable position for storing test tubes. This design allows the test tube rack 34 to be easily pulled out when needed, and can be pushed back to one side of the body 1 when not in use, thereby saving space and ensuring the safe storage of the test tube rack 34. The handle 36 is designed to allow the user to more easily pull out or push the test tube rack 34 back into the storage device 3. This design can make operation more convenient and comfortable.
