Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a flip-top self-locking high-speed centrifuge. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquids and solid particles or liquids and liquids.

[0003] Centrifuges are common laboratory equipment. After the experimental liquid is centrifuged, the operator studies the separated liquid and obtains experimental data. Because the centrifuge rotates at extremely high speeds, the machine will vibrate continuously each time it runs. Due to prolonged vibration, the centrifuge may occasionally experience circuit failures. If the machine stops running due to a failure and does not give a clear indication, the operator may take out the experimental liquid that has not been centrifuged and use it for experiments, which will greatly affect the accuracy of the experimental data. Utility Model Content

[0004] The purpose of this application is to provide a flip-top self-locking high-speed centrifuge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A flip-top self-locking high-speed centrifuge includes a top cover and a housing, as well as a self-locking assembly installed on one side of the top cover. One end of the outer wall of the top cover is rotatably connected to the outer wall of the housing, with a torsion spring installed at the connection. The self-locking assembly includes a locking block and an electromagnetic lock. The locking block is fixedly installed on one end of the outer wall of the top cover, and the electromagnetic lock is fixedly installed on the outer wall of the housing. The outer wall of the electromagnetic lock has a locking groove. The electromagnetic lock is made of an electromagnet, and its circuit is controlled by a control terminal inside the housing. The shape of the locking block is adapted to the locking groove. A sleeve is fixedly installed on the side of the top cover away from the locking block, and a fixing rod is fixedly installed on one side of the housing. The sleeve is fitted over the fixing rod, and a torsion spring is installed between the inner wall of the sleeve and the fixing rod. A rubber strip is embedded in the top edge of the housing.

[0007] Preferably, both the locking blocks and the locking grooves are arranged in two sets. A fixing plate is fixedly installed between the two locking blocks. The outer wall of the fixing plate has an insertion hole. A movable block is movably installed on the outer wall of the electromagnetic lock. The shape of the movable block is adapted to the shape of the insertion hole. The outer wall of the electromagnetic lock has a slot. The movable block is embedded in the slot. A spring is fixedly installed between the movable block and the inner wall of the slot. The movable block is made of ferrous metal. The outer wall of the locking block has a groove. The groove is arc-shaped. A protrusion is fixedly installed on the inner wall of the locking groove. The shape of the protrusion is adapted to the shape of the groove.

[0008] The beneficial effects of this utility model are: by setting a self-locking component, the moving block enters the insertion hole, which can lock the locking block and locking groove, prevent the end cap from being opened by mistake, ensure that the experimental liquid is not taken out, and at the same time prompt the operator to inspect the centrifuge.

[0013] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0014] like Figs. 1-3 The disclosed high-speed centrifuge features a flip-top self-locking design, comprising a top cover 1, a housing, and a self-locking assembly mounted on one side of the top cover 1. One end of the outer wall of the top cover 1 is rotatably connected to the outer wall of the housing, with a torsion spring installed at the connection point. The self-locking assembly includes a locking block 4 and an electromagnetic lock 2. The locking block 4 is fixedly mounted on one end of the outer wall of the top cover 1, and the electromagnetic lock 2 is fixedly mounted on the outer wall of the housing. The outer wall of the electromagnetic lock 2 has a locking groove 3. The electromagnetic lock 2 is made of electromagnet, and its circuit is controlled by an internal control terminal within the housing. The shape of the locking block 4 is adapted to the locking groove 3. A sleeve is fixedly mounted on the side of the top cover 1 away from the locking block 4, and a fixing rod is fixedly mounted on one side of the housing. The sleeve is fitted over the fixing rod, and a torsion spring is installed between the inner wall of the sleeve and the fixing rod. A rubber strip is embedded in the top edge of the housing.

[0015] Both the locking block 4 and the locking groove 3 are arranged in two sets. A fixing plate 5 is fixedly installed between the two locking blocks 4. The outer wall of the fixing plate 5 has an insertion hole 6. A movable block 7 is movably installed on the outer wall of the electromagnetic lock 2. The shape of the movable block 7 matches the shape of the insertion hole 6. The outer wall of the electromagnetic lock 2 has a slot 8. The movable block 7 is embedded in the slot 8. A spring 9 is fixedly installed between the movable block 7 and the inner wall of the slot 8. The movable block 7 is made of iron metal. The outer wall of the locking block 4 has a slot 10. The slot 10 is an arc-shaped groove. A protrusion is fixedly installed on the inner wall of the locking groove 3. The shape of the protrusion matches the shape of the slot 10.

[0016] Example: The operator puts the liquid to be tested into the centrifuge housing. In the initial state, the sleeve at the end of the top cover 1 is in the open state driven by the torsion spring. After the liquid is put in, the start button is pressed, the electromagnetic lock 2 is energized, the moving block 7 is attracted into the slot 8, the spring 9 is compressed, and the locking block 4 is made of plastic. The operator inserts the locking block 4 into the locking groove 3. The protrusion inside the locking groove 3 and the slot 10 on the side wall of the locking block 4 engage. At this time, the top cover 1 is closed, and the centrifuge starts to run after closing.

[0017] If the centrifuge is operating normally, after centrifugation, the operator opens the top cover 1, and the locking block 4 separates from the locking groove 3. If the centrifuge malfunctions due to a circuit problem during operation, causing it to stop running, the experimental liquid that has not completed centrifugation may be taken out by the operator, which will have a significant impact on subsequent experimental data. Therefore, after a circuit failure occurs, in order to prevent the experimental liquid from being mistakenly taken out by the operator, the centrifuge will be powered off. After the electromagnetic lock 2 is powered off, it loses its magnetic attraction, and the moving block 7 is pushed by the spring 9, causing the moving block 7 to enter the insertion hole 6 of the fixed plate 5. This locks the locking block 4 and the locking groove 3, preventing it from being opened by mistake. After the centrifuge is repaired, the electromagnetic lock 2 is powered on, and the moving block 7 is attracted into the groove 8, allowing the operator to open the top cover 1 again.

[0018] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

[0019] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
