Description

Technical Field

[0001] This application relates to the field of centrifuge technology, and in particular to a centrifuge for use in a cosmetics development laboratory. Background Technology

[0002] In cosmetic development laboratories, centrifuges are an indispensable key piece of equipment. Their main function is to generate powerful centrifugal force through high-speed rotation, and to effectively separate different components in cosmetic raw materials, semi-finished products, or finished products based on differences in material density. This process is of vital importance for cosmetic quality control, component analysis, and new product development.

[0003] A search revealed a Chinese utility model patent (publication number: CN222428264U) that discloses an easy-to-handle centrifuge. One end of the telescopic block is connected to a clamping plate, which can hold the sample tubes and simultaneously remove them. This allows for rapid and batch processing of sample tubes, greatly improving work efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] The clamping method used in existing centrifuges relies solely on springs and clamps to hold the ends of the sample tubes. During long-term and frequent use, the springs are prone to fatigue and aging, resulting in a decrease in the elastic coefficient and a weakening of the clamping force. Once the springs age, the clamping stability of the sample tube ends cannot be reliably guaranteed when the sample tube is removed as a whole after high-speed centrifugation.

[0006] Therefore, in response to the above problems, the applicant provides a centrifuge for cosmetic development laboratories. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a centrifuge for cosmetic development laboratories.

[0008] This application provides a centrifuge for a cosmetic development laboratory, which adopts the following technical solution:

[0009] A centrifuge for a cosmetic development laboratory includes a centrifuge body and a connecting plate. A rotating disk is rotatably mounted inside the centrifuge body, and a plurality of placement cylinders are fixed on the rotating disk, with the plurality of placement cylinders evenly distributed on the rotating disk.

[0010] The outer wall of the connecting plate is provided with a placement mechanism that can support the bottom of the sample tube. The number of placement mechanisms corresponds to the number of placement cylinders. The outer wall of the placement cylinder is provided with a side groove that communicates with the inner cavity of the placement cylinder.

[0011] The placement mechanism includes a fixing ring for clamping the sample tube, a connecting rod fixed to the bottom of the fixing ring, two connecting rods, the bottoms of the two connecting rods being fixedly connected to the same support plate, a fixing rod fixed to the outer wall of the fixing ring, and the fixing rod being detachably connected to the connecting plate.

[0012] Optionally, the top of the connecting plate is provided with an arc-shaped groove, the bottom center of the connecting plate is fixed with a first insert rod, and the bottom of the connecting plate is shaped like an equilateral triangle and fixed with a second insert rod.

[0013] Optionally, a first insertion cylinder is fixed at the top center of the rotating disk, and a second insertion cylinder is fixed at the top of the rotating disk in the shape of an equilateral triangle. The first insertion cylinder is inserted into and cooperates with the first insertion rod, and the second insertion cylinder is inserted into and cooperates with the second insertion rod.

[0014] Optionally, a positioning hole is provided at the end of the fixing rod away from the fixing ring.

[0015] Optionally, the connecting plate is provided with a positioning mechanism for positioning the fixed rod. The positioning mechanism includes a slot formed in the side wall of the connecting plate, a circular groove formed on the top surface of the inner wall of the slot, a through hole formed on the top of the connecting plate communicating with the circular groove, a T-shaped rod fitted with the circular groove with clearance, a spring sleeved on the outer wall of the T-shaped rod, the top of the spring being fixedly connected to the top of the inner wall of the circular groove, and when the fixed rod is inserted into the slot, the bottom of the T-shaped rod engaging with the positioning hole.

[0016] Optionally, the top of the T-shaped rod has a through hole, and a circular handle is fixedly connected to the through end of the T-shaped rod.

[0017] Optionally, the top of the tray is provided with a groove, and a silicone pad is provided in the groove. The tray is in clearance fit with the inner cavity of the placement cylinder.

[0018] Optionally, when the tray extends into the inner cavity of the placement cylinder, the connecting rod slides into the side groove.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model, through the structural design of a fixing ring, connecting rod, support plate, and fixing rod, provides reliable support for the bottom of the sample tube when it is removed as a whole after high-speed centrifugation. Compared with the prior art that only clamps the end of the sample tube, it greatly reduces the risk of the sample tube falling off and breaking due to aging of the clamping parts or unstable clamping. It keeps the test tube stable throughout the entire removal process, ensuring the integrity of the sample inside the tube and avoiding sample loss due to test tube falling off.

[0021] 2. Through the structural design of the slot, the circular groove, the fixing rod, the T-shaped circular rod and the spring, each placement mechanism has an individual quick-release function. When a placement mechanism is partially damaged due to long-term use, the staff only needs to quickly remove the damaged placement mechanism and replace it with a new part, which reduces the cost of maintenance and replacement.

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses a centrifuge for use in a cosmetics development laboratory.

[0032] like Figure 1-7As shown, a centrifuge for a cosmetic development laboratory includes a centrifuge body 1 and a connecting plate 4. A sealing cover is hinged to the centrifuge body 1. A rotating disk 2 is rotatably installed inside the centrifuge body 1. The rotating disk 2 is usually made of aluminum alloy or high-strength alloy steel, which has a light weight and high strength. Its shape is a circular flat plate. Several placement cylinders 3 are fixed on the rotating disk 2. The placement cylinders 3 are evenly distributed on the rotating disk 2 and are used to hold sample tubes. The placement cylinders 3 are made of stainless steel or high-strength plastic, which has good corrosion resistance and mechanical strength. Their shape is cylindrical, and the inner wall is polished to reduce friction on the sample tubes.

[0033] Please see Figure 2 , Figure 3 and Figure 5 The top of the connecting plate 4 has a through arc-shaped groove designed to facilitate the installation and disassembly of the placement mechanism 5. A first insert rod is fixed at the center of the bottom of the connecting plate 4, and a second insert rod is fixed at the bottom of the connecting plate 4 in an equilateral triangle shape. A first insert cylinder is fixed at the center of the top of the rotating disk 2, and a second insert cylinder is fixed at the top of the rotating disk 2 in an equilateral triangle shape. The first insert cylinder is inserted into the first insert rod, and the second insert cylinder is inserted into the second insert rod. The inner diameter and depth of the first insert cylinder and the second insert cylinder are precisely machined according to the dimensions of the first insert rod and the second insert rod to ensure the fitting accuracy between the two.

[0034] The outer wall of the connecting plate 4 is provided with a placement mechanism 5 that can support the bottom of the sample tube. The number of placement mechanisms 5 corresponds to the number of placement cylinders 3. The outer wall of the placement cylinder 3 is provided with a side groove 300 that communicates with the inner cavity of the placement cylinder 3.

[0035] The placement mechanism 5 includes a fixing ring 500 for clamping sample tubes. The inner wall of the fixing ring 500 has multiple grooves, each containing a compression spring. One end of each compression spring is connected to a telescopic block, and one end of the telescopic block is connected to an arc-shaped clamping plate for clamping and positioning sample tubes containing cosmetic production-related raw materials. Two connecting rods 501 are fixed to the bottom of the fixing ring 500, and the bottoms of both connecting rods 501 are fixedly connected to the same support plate 502. (See also...) Figure 5The top of the tray 502 has a groove with a silicone pad inside. The tray 502 is fitted with the inner cavity of the placement cylinder 3 with a clearance. When the tray 502 is inserted into the inner cavity of the placement cylinder 3, the connecting rod 501 slides with the side groove 300. The shape and size of the groove are adapted to the bottom of the sample tube, providing stable support for the sample tube. The silicone pad has good elasticity and anti-slip properties, which can further protect the bottom of the sample tube and increase the friction between the tray 502 and the sample tube, preventing the sample tube from sliding on the tray 502. The tray 502 can move freely up and down in the placement cylinder 3 without affecting the stability of the sample tube due to shaking. When the tray 502 is inserted into the inner cavity of the placement cylinder 3, the connecting rod 501 slides with the side groove 300 to ensure the stability of the placement mechanism 5 during rotation.

[0036] A fixing rod 503 is fixed to the outer wall of the fixing ring 500. Please refer to [link / reference]. Figure 6 The fixing rod 503 has a positioning hole 5030 at the end away from the fixing ring 500. The fixing rod 503 is detachably connected to the connecting plate 4. Please refer to [link / reference]. Figure 6 and Figure 7 The connecting plate 4 is equipped with a positioning mechanism for positioning the fixing rod 503. The positioning mechanism includes a slot 400 formed on the side wall of the connecting plate 4. The width and depth of the slot 400 are designed according to the dimensions of the fixing rod 503 for insertion and positioning. A circular groove 401 is formed on the top surface of the inner wall of the slot 400. A through hole 402 communicating with the circular groove 401 is formed on the top of the connecting plate 4. A T-shaped rod 6 is fitted with the circular groove 401 with clearance. A spring 601 is sleeved on the outer wall of the T-shaped rod 6. The top of the spring 601 is fixedly connected to the top of the inner wall of the circular groove 401. When the fixing rod 503 is inserted into the slot 400, the bottom of the T-shaped rod 6 engages with the positioning hole 5030. The diameter and depth of the positioning hole 5030 are designed according to the thick cylindrical end of the T-shaped rod 6 in the positioning mechanism, and are used to cooperate with the positioning mechanism to achieve quick installation and fixation of the placement mechanism 5. Please refer to [link to relevant documentation]. Figure 6 and Figure 7 The thin cylindrical end of the T-shaped rod 6 passes through the through hole 402. A circular handle is fixedly connected to the through end of the T-shaped rod 6. When the fixing rod 503 is inserted into the slot 400, the T-shaped rod 6 moves downward under the action of the spring 601. Its thick cylindrical end cooperates with the positioning hole 5030 to realize the positioning of the fixing rod 503. The circular handle makes it convenient for the operator to manually operate the T-shaped rod 6 to disengage it from the positioning hole 5030, thereby realizing the disassembly of the placement mechanism 5.

[0037] The implementation principle of a centrifuge for a cosmetic development laboratory according to an embodiment of this application is as follows:

[0038] When retrieving the centrifuged sample tubes, the operator lifts the connecting plate 4 upwards, allowing the support plate 502 to move upwards from the inner cavity of the placement cylinder 3. This process continues until the support plate 502 is completely separated from the inner cavity of the placement cylinder 3, completing the synchronous unloading of all sample tubes. During unloading, the support plate 502 provides reliable support for the bottom of the sample tubes. Compared to existing technologies that only clamp the ends of the sample tubes, this significantly reduces the risk of sample tubes falling off and breaking due to aging or unstable clamping parts. It ensures the test tubes remain stable throughout the entire removal process, guaranteeing the integrity of the samples inside and preventing sample loss due to test tube detachment.

[0039] When one of the placement mechanisms 5 is damaged, pull the circular handle upward. The circular handle will cause the thick cylindrical end of the T-shaped rod 6 to extend out of the positioning hole 5030. During this process, the thick cylindrical end of the T-shaped rod 6 compresses the spring 601. After inserting the fixing rod 503 in the new placement mechanism 5 into the slot 400, release the circular handle. Under the reset of the spring 601, the T-shaped rod 6 will be inserted back into the positioning hole 5030 to complete the fixing.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
