Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal equipment, in particular to a sample centrifugal device for antibody preparation. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. In medicine, centrifuges are usually instruments used to separate raw materials such as blood and plasma for inspection. During the high-speed rotation of the centrifuge rotor, the particles inside the raw materials sink faster, separating substances of different densities.

[0003] The existing sample centrifuge device for antibody preparation can only use centrifuge tubes of the same size during use, which is inconvenient to separate raw materials inside centrifuge tubes of different sizes and has low applicability. Utility Model Content

[0004] The utility model aims to solve the technical problems in the above background and provides a sample centrifugal device for antibody preparation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sample centrifugal device for antibody preparation, comprising a base, a motor is fixedly mounted on the surface of the base, a placement tube is fixedly mounted on the output end of the motor, a centrifugal sleeve is placed inside the placement tube, and a clamping device is provided on the outer wall surfaces on both sides of the placement tube, and the clamping device comprises two round rods, the two round rods are fixedly mounted on the outer wall surfaces on both sides of the placement tube, and the two round rods are fixedly mounted on the end surfaces away from the placement tube, and a threaded rod is rotatably connected between the two support frames. The setting of the support frame plays an effect of supporting the threaded rod.

[0006] Preferably, a rotating wheel is fixedly mounted on the surface of the threaded rod, and the threads on the surface of the threaded rod are mutually reverse threads with the rotating wheel as the center. The setting of the rotating wheel plays the effect of driving the threaded rod to rotate.

[0007] Preferably, a slide bar is fixedly installed between the two support frames, two movable plates are threadedly connected to the surface of the threaded bar, and a clamping plate is fixedly installed on the side of the movable plate. The setting of the threaded bar has the effect of driving the movable plate to move on the surface of the slide bar, and the setting of the clamping plate has the effect of clamping and fixing the centrifugal casing.

[0008] Preferably, the surfaces of the two clamping plates are provided with protective devices, the protective devices comprising through holes, the through holes are provided on the surfaces of the clamping plates, a mounting rod is movably inserted inside the through holes, and a protective pad is fixedly installed at one end of the mounting rod. The provision of the protective pad has the effect of preventing the clamping plates from directly contacting the centrifugal casing.

[0009] Preferably, a vertical rod is fixedly mounted on the side of the clamping plate, a movable plate is slidably connected to the surface of the vertical rod, an insertion rod is fixedly mounted on the surface of the movable plate, and a plurality of insertion holes are formed in an annular shape on the outer wall surface of the mounting rod. The arrangement of the insertion rod and the insertion holes has the effect of limiting the mounting rod inside the through hole.

[0010] Preferably, a limiting plate is fixedly installed on the surface of one end of the vertical rod away from the clamping plate, and a spring is fixedly installed between the limiting plate and the movable plate. The setting of the spring has the effect of limiting the position of the movable plate on the surface of the vertical rod.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting a clamping device, when the device is needed, first, the centrifugal casing is placed inside the placing cylinder, and then the rotating wheel is rotated according to the size of the centrifugal casing. The rotation of the rotating wheel drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are mutually reverse threads with the rotating wheel as the center, when the rotating wheel drives the threaded rod to rotate, the two movable plates threadedly connected on the surface of the sliding rod move in the direction away from or close to each other on the surface of the sliding rod, and the two movable plates move in the direction away from or close to each other on the surface of the sliding rod, driving the two clamping plates to move in the direction away from or close to each other. The two clamping plates move in the direction away from or close to each other to clamp and fix the centrifugal casing. When the centrifugal casing is clamped, the motor is started, and the motor starts to drive the placing cylinder to rotate. The rotation of the placing cylinder drives the centrifugal casing to rotate. The centrifugal casing rotates to complete the corresponding centrifugal operation. Through the cooperation of the above structure, the distance between the two clamping plates can be adjusted according to the size of the centrifugal casing, so that the device can clamp and fix centrifugal casings of different sizes, further improving the adaptability of the device.

[0013] When the locking plate is in a position to move, the locking plate is released and the locking plate is engaged with the locking member, thereby preventing the locking plate from being in direct contact with the locking member and causing the locking member to be locked.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] The specific arrangement and function of the clamping device 5 and the protective device 6 will be described in detail below.

[0024] In this embodiment: the outer wall surfaces on both sides of the placing cylinder 3 are provided with clamping devices 5, and the clamping devices 5 include two round rods 51, and the two round rods 51 are fixedly installed on the outer wall surfaces on both sides of the placing cylinder 3. The end surfaces of the two round rods 51 away from the placing cylinder 3 are fixedly installed with support frames 52, and a threaded rod 53 is rotatably connected between the two support frames 52.

[0025] In this embodiment, the support frame 52 is provided to support the threaded rod 53 .

[0026] Specifically, a rotating wheel 54 is fixedly mounted on the surface of the threaded rod 53 , and the threads on the surface of the threaded rod 53 are reverse threads with the rotating wheel 54 as the center.

[0027] In this embodiment, the setting of the rotating wheel 54 plays the effect of driving the threaded rod 53 to rotate.

[0028] Specifically, a slide bar 55 is fixedly installed between the two support frames 52, two movable plates 56 are threadedly connected to the surface of the threaded rod 53, and a clamping plate 57 is fixedly installed on the side of the movable plate 56. The setting of the threaded rod 53 has the effect of driving the movable plate 56 to move on the surface of the slide bar 55, and the setting of the clamping plate 57 has the effect of clamping and fixing the centrifugal casing 4.

[0029] In this embodiment: the surfaces of the two clamping plates 57 are provided with a protective device 6, and the protective device 6 includes a through hole 61, and the through hole 61 is opened on the surface of the clamping plate 57. A mounting rod 62 is movably inserted inside the through hole 61, and a protective pad 63 is fixedly installed at one end of the mounting rod 62. When it is necessary to avoid direct contact between the clamping plate 57 and the centrifugal casing 4, first slide the movable plate 65 so that the movable plate 65 moves on the surface of the vertical rod 64. The movement of the movable plate 65 on the surface of the vertical rod 64 will squeeze the spring 69, so that the spring 69 is compressed. At the same time, the movement of the movable plate 65 on the surface of the vertical rod 64 also drives the insertion rod 66 to move. When the insertion rod 66 moves to a suitable position, the mounting rod 62 is inserted into the interior of the through hole 61. After the mounting rod 62 and the through hole 61 are inserted, the movable plate 65 is released, and the rebound of the spring 69 is utilized. The force causes the insertion rod 66 to reset, and the insertion rod 66 resets itself and then inserts itself into the inside of the socket 67. The insertion rod 66 and the socket 67 are plugged together, so that the installation rod 62 is limited inside the through hole 61. The installation operation of the protective pad 63 is completed. Through the cooperation of the above-mentioned structure, the purpose of installing the protective pad 63 is achieved, so that when the clamping plate 57 clamps and fixes the centrifugal sleeve 4, the protective pad 63 can prevent the clamping plate 57 from directly contacting the centrifugal sleeve 4 and causing damage to the centrifugal sleeve 4.

[0030] Specifically, a vertical rod 64 is fixedly installed on the side of the clamping plate 57, a movable plate 65 is slidably connected to the surface of the vertical rod 64, an insertion rod 66 is fixedly installed on the surface of the movable plate 65, and a plurality of insertion holes 67 are annularly provided on the outer wall surface of the installation rod 62.

[0031] In this embodiment, the provision of the insertion rod 66 and the insertion hole 67 has the effect of limiting the installation rod 62 inside the through hole 61 .

[0032] Specifically, a limiting plate 68 is fixedly installed on the surface of one end of the vertical rod 64 away from the clamping plate 57 , and a spring 69 is fixedly installed between the limiting plate 68 and the movable plate 65 .

[0033] In this embodiment, the setting of the spring 69 has the effect of limiting the position of the moving plate 65 on the surface of the vertical rod 64 .

[0034] Working principle: By setting the clamping device 5, when the device needs to be used, first place the centrifugal sleeve 4 inside the placing cylinder 3, then according to the size of the centrifugal sleeve 4, rotate the rotating wheel 54, and the rotating wheel 54 drives the threaded rod 53 to rotate. Since the threads on the surface of the threaded rod 53 are mutually reverse threads with the rotating wheel 54 as the center, when the rotating wheel 54 drives the threaded rod 53 to rotate, the two movable plates 56 connected by the threads on its surface move in the direction of moving away from or approaching each other on the surface of the sliding rod 55, and the two movable plates 56 move in the direction of moving away from or approaching each other on the surface of the sliding rod 55, driving the two clamping The plates 57 move in a direction away from or close to each other, and the two clamping plates 57 move in a direction away from or close to each other to clamp and fix the centrifugal sleeve 4. When the centrifugal sleeve 4 is clamped, the motor 2 is started, and the motor 2 starts to drive the placement cylinder 3 to rotate, and the rotation of the placement cylinder 3 drives the centrifugal sleeve 4 to rotate, and the centrifugal sleeve 4 rotates to complete the corresponding centrifugal operation. Through the cooperation of the above structure, the distance between the two clamping plates 57 can be adjusted according to the size of the centrifugal sleeve 4, so that the device can clamp and fix centrifugal sleeves 4 of different sizes, further improving the adaptability of the device. When it is necessary to avoid direct contact between the clamping plate 57 and the centrifugal sleeve 4, first slide the movable plate 65 to move the movable plate 65 on the surface of the vertical rod 64. The movement of the movable plate 65 on the surface of the vertical rod 64 will squeeze the spring 69, so that the spring 69 is compressed. At the same time, the movement of the movable plate 65 on the surface of the vertical rod 64 also drives the insertion rod 66 to move. When the insertion rod 66 moves to a suitable position, the installation rod 62 is inserted into the interior of the through hole 61. After the installation rod 62 and the through hole 61 are inserted, the movable plate 65 is released, and the spring 69 is used to rebound. The force causes the insertion rod 66 to reset, and the insertion rod 66 resets itself and then inserts itself into the inside of the socket 67. The insertion rod 66 and the socket 67 are plugged together, so that the installation rod 62 is limited inside the through hole 61. The installation operation of the protective pad 63 is completed. Through the cooperation of the above-mentioned structure, the purpose of installing the protective pad 63 is achieved, so that when the clamping plate 57 clamps and fixes the centrifugal sleeve 4, the protective pad 63 can prevent the clamping plate 57 from directly contacting the centrifugal sleeve 4 and causing damage to the centrifugal sleeve 4.
