Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of centrifuge accessories, specifically, it relates to a capillary rotor frame. Background Technology
[0002] A centrifuge is a device that uses centrifugal force to separate mixed liquids or particles. It can be widely used in education, scientific research, environmental protection, medicine, metrology, health, food, chemical industry, light industry, agriculture, materials, epidemic prevention and other departments, and is an essential instrument in routine laboratories.
[0003] The rotor is the core component of a centrifuge, used to carry samples and generate centrifugal force during high-speed rotation to separate mixtures. Rotors are typically made of high-strength metals (such as aluminum alloys and titanium alloys) or composite materials and must withstand extremely high mechanical stress. Depending on the application, rotors can generally be classified into fixed-angle rotors, horizontal rotors, and special-purpose rotors. Capillary rotors are a type of special-purpose rotor, a specially designed rotor primarily used for analyzing trace samples (such as blood, proteins, and nucleic acids). Capillary rotors are irreplaceable in scientific research fields (such as structural biology), but they are costly and complex to operate, primarily used for high-end research rather than routine separation.
[0004] Currently, capillary rotors on the market generally have a special structural design, making it difficult to remove or place the capillary tube inside the rotor body, and making it inconvenient to clean and disinfect the rotor body. Utility Model Content
[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a capillary rotor frame.
[0006] According to the present invention, a capillary rotor frame is provided, the shape of which is adapted to the sleeve engagement structure of the mainstream centrifuge rotor. The capillary rotor frame is divided into two parts: an outer protective shell and an inner movable frame. The inner movable frame is limited and set inside the outer protective shell, and the inner movable frame slides correspondingly with the outer protective shell.
[0007] In a preferred embodiment: the internal movable frame consists of a push rod, a silicone gasket, a push block, and an annular sealing ring.
[0008] In a preferred embodiment: a long sliding hole is provided in the middle of the push rod.
[0009] In a preferred embodiment: the top of the push rod has several annularly arranged circular holes for placing capillary tubes, which are long and thin tubes made of glass.
[0010] In a preferred embodiment: a silicone washer is installed at the bottom of the push rod, the silicone washer being used to support and protect the lower end of the capillary tube.
[0011] In a preferred embodiment: the lower end of the push rod is connected to a short round rod, and a silicone gasket is sleeved on the upper side of the short round rod. A push block is sleeved in the middle of the short round rod, and an annular groove is opened at the tail of the short round rod. An annular sealing ring is inserted into the annular groove. The push rod, silicone gasket and push block are tightly assembled through the annular sealing ring to form a linked internal movable frame.
[0012] In a preferred embodiment, a boss is fixedly installed on the left end of the push block.
[0013] In a preferred embodiment: the outer protective shell consists of a back plate, a buckle plate, and a hand-locking screw. The back plate and buckle plate together form a square track, and the internal movable frame can slide up and down within the square track.
[0014] In a preferred embodiment: the screw holes in the middle of the back plate and the buckle plate are corresponding to the hand-locking screws, and the long sliding hole is slidably disposed with the hand-locking screws. The hand-locking screws fix the back plate and the buckle plate together through the long sliding hole in the middle of the push rod.
[0015] In a preferred embodiment: an elongated hole is provided on the back plate, and the elongated hole slides with the boss to limit the movement, so as to realize the lifting and lowering of the internal movable frame by pushing it from the outside of the capillary rotor frame through the boss.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In use, this invention uses an annular sealing ring to engage and limit the push rod, silicone gasket, and push block, forming an internal movable frame. A hand-locking screw is used to fix the back plate and buckle plate through the long sliding hole in the middle of the push rod. This design makes the capillary placement structure a separate component of the capillary rotor frame, improving the ease of assembly and disassembly of the capillary rotor frame and aiding in cleaning and disinfection. Simultaneously, the push-up boss slides within the long slot on the back plate, and the push block, in conjunction with this, moves the push rod back and forth within the square track, allowing the capillary to be exposed on the internal movable frame for easy access.

[0023] Detailed Implementation
[0024] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0025] like Figure 1 and Figure 2 As shown, this utility model discloses a capillary rotor frame, including a capillary rotor frame 11. The shape of the capillary rotor frame 11 is adapted to the locking structure of the protective sleeve 12 of the mainstream centrifuge rotor, so that the capillary rotor frame 11 becomes an independent universal rotor component. The capillary rotor frame 11 is divided into two parts: an outer protective shell and an inner movable frame. The inner movable frame is limited and set inside the outer protective shell, and the inner movable frame slides correspondingly with the outer protective shell.
[0026] The internal movable frame consists of a push rod 3, a silicone gasket 5, a push block 8, and an annular sealing ring 9. The push rod 3 has a long sliding hole in its middle that corresponds to the hand-locking screw 6. The top of the push rod 3 has four annularly arranged circular holes for placing capillary tubes 2. The capillary tubes 2 are slender glass tubes used for blood separation. A silicone gasket 5 is installed at the bottom of the push rod 3 to support and protect the lower end of the capillary tube 2. A short round rod is connected to the lower end of the push rod 3, and the silicone gasket... 5 are set on the upper side of the short round rod. A push block 8 is set in the middle of the short round rod. A boss 10 is fixedly installed on the left end of the push block 8. An annular groove 7 is opened at the tail of the short round rod. An annular sealing ring 9 is inserted into the annular groove 7. Thus, the push rod 3, silicone gasket 5 and push block 8 are tightly assembled through the annular sealing ring 9 to form a linked internal movable frame. The push rod 3, silicone gasket 5 and push block 8 can be disassembled through the annular sealing ring 9, which facilitates the disassembly and cleaning of the push rod 3, silicone gasket 5 and push block 8.
[0027] The outer protective shell consists of a back plate 1, a buckle plate 4, and a hand-locking screw 6. The back plate 1 and buckle plate 4 together form a square track. The square track is used to accommodate the internal movable frame, which consists of a push rod 3, a silicone gasket 5, a push block 8, and an annular sealing ring 9. The internal movable frame can slide up and down within the square track. The screw holes in the middle of the back plate 1 and buckle plate 4 correspond to the hand-locking screw 6. The hand-locking screw 6 fixes the back plate 1 and buckle plate 4 together through the long sliding hole in the middle of the push rod 3. In the subsequent disassembly process, the square track can be separated simply by rotating the hand-locking screw 6 from the back plate 1, which facilitates the quick disassembly and assembly of the shell of its internal structure. The back plate 1 has a long slotted hole that slides and limits the boss 10, so as to realize the lifting and lowering of the internal movable frame through the boss 10 from the outside of the capillary rotor frame 11.
[0028] like Figure 3 As shown, a common horizontal rotor 13 has several protective sleeves 12 installed in a ring inside. The protective sleeves 12 are used to protect and prevent centrifuge tubes from being separated. The capillary rotor frame 11 can be placed inside the protective sleeves 12 of the horizontal rotor 13 to perform corresponding centrifugal rotation to separate samples.
[0029] like Figure 4 As shown, a common angle rotor 14 has several protective sleeves 12 installed in a ring inside. The multiple protective sleeves 12 are installed at an angle on the rotor seat. The capillary rotor frame 11 can be placed inside the protective sleeves 12 of the angle rotor 14 to perform corresponding centrifugal rotation to separate the sample.
[0030] Working principle
[0031] In use, this utility model uses the annular sealing ring 9 to engage and limit the push rod 3, silicone gasket 5, and push block 8 to form an internal movable frame. The hand-locking screw 6 is used to fix the back plate 1 and buckle plate 4 through the long sliding hole in the middle of the push rod 3. Thus, the capillary placement structure is designed as a separate component of the capillary rotor frame 11. This not only improves the ease of disassembly and assembly of the capillary rotor frame 11 and helps with cleaning and disinfection, but also allows it to be installed with the protective sleeve 12 of the centrifuge rotor commonly used in the market. This makes it convenient to use in various centrifuges and different types of rotors, such as horizontal rotors 13 and angle rotors 14, reducing the manufacturing cost of the capillary rotor and expanding the application of other centrifuges.
[0032] Secondly, by moving the boss 10 to slide within the elongated hole on the back plate 1, and cooperating with the push block 8 to make the push rod 3 slide back and forth in the square track, it can both expose the capillary tube on the internal movable frame for easy access, and also send the capillary tube on the internal movable frame back into the square track to ensure that it can be well protected during centrifugal separation.
