Description

Technical Field

[0001] The present invention relates to the technical field of scientific experimental devices, and particularly to a self-tightening gland three-dimensional oscillating bead homogenizer. Background Art

[0002] In experiments such as bioscience, environmental science, and food science, bead homogenizers mainly fall into two types:

[0003] 1. The oscillating grinding method is horizontal or vertical linear reciprocating motion: This type of oscillating grinding has a very low speed, and there are problems of low homogenization and crushing efficiency, poor effect, and high vibration and noise.

[0004] 2. The oscillating grinding method is three-dimensional oscillating motion: The moving direction of the oscillating head of this type is clockwise, but the fixing screws of the oscillating head, gland, etc. are also clockwise. In the case of high-speed oscillation, it often leads to the risk of easy detachment of the gland, grinding tube, and grinding tube adapter, and the vibration and noise are extremely high. At present, springs are mostly used as anti-torsion devices, with low strength, easy wear, easy corrosion, and very poor durability. Because of the high oscillation speed, the grinding tube is easy to rupture, and the internal biological samples are easy to leak and enter the electrical components below the equipment, resulting in equipment damage. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-tightening gland three-dimensional oscillating bead homogenizer to solve the problems raised in the above background art.

[0006] The present invention provides the following technical solution: a self-tightening gland three-dimensional oscillating grinding bead homogenizer, comprising a reverse-thread self-locking anti-overtightening safety cap, a safety gland, a reverse-thread oscillating head, a rubber ball shock-absorbing base and a power system. The reverse-thread self-locking anti-overtightening safety cap includes a telescopic rotary indexing pin, a knob disc and a reverse-thread inner thread sleeve of the rotary cap. The safety gland includes a gland and a gland positioning indexing disc. A first through hole is formed in the gland positioning indexing disc, and a first circlip is fixedly installed in the first through hole. The gland passes through the first through hole in the gland positioning indexing disc and is fixedly connected to the first circlip. The reverse-thread self-locking anti-overtightening safety cap and the safety gland are assembled into a reverse-thread self-locking anti-overtightening safety gland. The reverse-thread oscillating head includes an oscillating head reverse-thread fixing shaft, an oscillating head upper cover, a bearing fixing pin, an oscillating head bearing, an oscillating head lower cover and an eccentric shaft. The rubber ball shock-absorbing base includes an oscillating head mounting base, rubber shock-absorbing balls, an equipment base, an equipment housing mounting chassis, equipment feet and an anti-torsion part fixing disc. The top end of each equipment foot is fixedly installed with an equipment housing mounting chassis. The power system includes a coupling, a motor, an eccentric shaft positioning bearing and a motor fixing frame. The motor fixing frame is fixedly installed below the oscillating head mounting base. A gland and a grinding tube adapter are placed above the oscillating head upper cover. A reverse thread is provided on the reverse-thread oscillating head. The reverse-thread self-locking anti-overtightening safety gland is connected to the reverse-thread oscillating head through the reverse thread. The reverse-thread oscillating head is locked to the coupling through the eccentric shaft passing through the eccentric shaft positioning bearing and is connected to the motor. The outer side of the oscillating head reverse-thread fixing shaft is threadedly connected with the reverse-thread inner thread sleeve of the rotary cap. A first anti-torsion positioning post is provided at the outer edge of the oscillating head lower cover. A rubber anti-torsion part is movably installed on the oscillating head lower cover through the first anti-torsion positioning post. A second anti-torsion positioning post is provided at the inner edge of the anti-torsion part fixing disc. The lower inner ring of the rubber anti-torsion part is sleeved on the inner edge of the anti-torsion part fixing disc and fixed through the second anti-torsion positioning post. The lower outer ring of the rubber anti-torsion part is sleeved on the edge of the equipment housing. The outer ring side of the eccentric shaft positioning bearing is fixedly connected to the motor fixing frame.

[0007] Preferably, the reverse-thread self-locking anti-overtightening safety cap can rotate relative to the safety gland.

[0008] Preferably, a first limiting groove is formed in the gland, a second limiting groove is formed in the grinding tube adapter. The gland is located above the grinding tube adapter. A first limiting post is provided on the oscillating head upper cover. The first limiting post respectively passes through the first limiting groove and the second limiting groove.

[0009] Preferably, the rubber anti-torsion part is a rubber ring with good sealing performance.

[0010] Preferably, a bevel surface is provided at the top end of the eccentric shaft.

[0011] Preferably, the bottom end of the bearing fixing pin extends into the top end of the eccentric shaft, and the outer side of the bearing fixing pin is fixedly connected to the inner ring side of the oscillating head bearing.

[0012] Preferably, the top end of the rubber damping ball is fixedly connected to the bottom end of the oscillating head mounting base, and the bottom end of the rubber damping ball is fixedly connected to the top end of the equipment base.

[0013] Compared with the prior art, the present invention provides a self-tightening gland three-dimensional oscillating grinding bead homogenizer, which has the following beneficial effects:

[0014] 1. For this self-tightening gland three-dimensional oscillating grinding bead homogenizer, the noise is further reduced, reducing the noise damage to the operator.

[0015] 2. For this self-tightening gland three-dimensional oscillating grinding bead homogenizer, the vibration of the equipment is further reduced, reducing the damage to the electrical components in the equipment caused by vibration and reducing the probability of the fastening screws loosening due to vibration. Therefore, the damage and failure rate of the equipment are reduced.

[0016] 3. For this self-tightening gland three-dimensional oscillating grinding bead homogenizer, the combined threads of the gland and the oscillating head are all counterclockwise threads. According to the inertia principle, when the gland and the oscillating head swing clockwise at high speed, the counterclockwise thread structure will make them tighter and tighter, fundamentally solving the problem of getting looser. Even in the absence of a locking mechanism to prevent loosening, it avoids the risk of the gland and the grinding tube adapter detaching from the oscillating head and flying out to injure the operator or damage the equipment.

[0017] 4. For this self-tightening gland three-dimensional oscillating grinding bead homogenizer, there is an automatic locking anti-loosening mechanism. After the grinding bead homogenizer starts and runs, the internal spring pin of the retractable rotary indexing pin of the automatic locking anti-loosening mechanism will automatically fall into the indexing hole of the indexing plate under the action of inertia, locking the gland in place. This not only prevents the knob disk from rotating counterclockwise too tightly, making it impossible to unscrew after shutdown, but also prevents the gland from continuing to move downward.

Specific embodiments

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] Please refer to Figures 1 - 3, the present invention provides a technical solution: a self-tightening gland three-dimensional oscillating grinding bead homogenizer, including a reverse-thread self-locking anti-overtightening safety cap, a safety gland, a reverse-thread oscillating head, a rubber ball shock-absorbing base and a power system. The reverse-thread self-locking anti-overtightening safety cap includes a telescopic rotary indexing pin 1, a knob disc 2 and a rotary cap reverse-thread inner thread sleeve 13. The safety gland includes a gland 3 and a gland positioning indexing disc 14. A first through hole is provided in the gland positioning indexing disc 14, and a first circlip is fixedly installed in the first through hole. The gland 3 passes through the first through hole in the gland positioning indexing disc 14 and is fixedly connected to the first circlip. The reverse-thread self-locking anti-overtightening safety cap and the safety gland are assembled into a reverse-thread self-locking anti-overtightening safety gland. The reverse-thread oscillating head includes an oscillating head reverse-thread screw fixing shaft 15, an oscillating head upper cover 16, a bearing fixing pin 17, an oscillating head bearing 18, an oscillating head lower cover 19 and an eccentric shaft 20. The rubber ball shock-absorbing base includes an oscillating head mounting base 6, a rubber shock-absorbing ball 7, an equipment base 8, an equipment housing mounting chassis 11, equipment feet 12 and an anti-torsion part fixing disc 21. The top of each equipment foot 12 is fixedly installed with an equipment housing mounting chassis 11. The power system includes a coupling 9, a motor 10, an eccentric shaft positioning bearing 22 and a motor fixing frame 23. The motor fixing frame 23 is fixedly installed below the oscillating head mounting base 6. The gland 3 and a grinding tube adapter 4 are placed above the oscillating head upper cover 16. A reverse thread is provided on the reverse-thread oscillating head. The reverse-thread self-locking anti-overtightening safety gland is connected to the reverse-thread oscillating head through the reverse thread. The reverse-thread oscillating head is locked to the coupling 9 through the eccentric shaft 20 passing through the eccentric shaft positioning bearing 22 and is connected to the motor 10. The outer side of the oscillating head reverse-thread screw fixing shaft 15 is threadedly connected to the rotary cap reverse-thread inner thread sleeve 13. A first anti-torsion positioning post is provided at the outer edge of the oscillating head lower cover 19. The oscillating head lower cover 19 is movably installed with a rubber anti-torsion part 5 through the first anti-torsion positioning post. A second anti-torsion positioning post is provided at the inner edge of the anti-torsion part fixing disc 21. The lower inner ring of the rubber anti-torsion part 5 is sleeved on the inner edge of the anti-torsion part fixing disc 21 and is fixed through the second anti-torsion positioning post. The lower outer ring of the rubber anti-torsion part 5 is sleeved on the edge of the equipment housing. The outer ring side of the eccentric shaft positioning bearing 22 is fixedly connected to the motor fixing frame 23. When the motor 10 operates, it drives the coupling 9 to rotate clockwise. The rotation of the coupling 9 drives the eccentric shaft 20 to rotate in the same direction. The rotation of the eccentric shaft 20 drives the inner ring of the eccentric shaft positioning bearing 22 to rotate in the same direction. The outer ring of the eccentric shaft positioning bearing 22 is fixed together with the motor fixing frame 23 and does not rotate. The eccentric shaft positioning bearing 22 keeps the eccentric shaft 20 vertical. The eccentric shaft 20 with a certain-angle inclined plane at the top rotates to drive the bearing fixing pin 17 to rotate in the same angle and in the same direction. The bearing fixing pin 17 drives the inner ring of the oscillating head bearing 18 to rotate in the same angle and in the same direction. The outer ring of the oscillating head bearing 18 is fixed together with the oscillating head reverse-thread screw fixing shaft 15, the oscillating head upper cover 16 and the oscillating head lower cover 19. The oscillating head lower cover 19 is pulled by the rubber anti-torsion part 5 and cannot rotate freely.The outer ring of the oscillating head bearing 18 does not rotate together with the inner ring of the oscillating head bearing 18. The above structure enables the outer ring of the oscillating head bearing 18, the reverse-thread fixed shaft 15, the upper cover 16 of the oscillating head, and the lower cover 19 of the oscillating head to swing in the same direction at the same angle along with the inner ring of the oscillating head bearing 18. The grinding tube adapter placed on the upper cover 16 of the oscillating head, and the retractable rotary indexing pin 1, the knob disk 2, the gland 3, the reverse-thread inner-thread sleeve 13 of the knob cover, and the gland positioning indexing disk 14 screwed onto the reverse-thread fixed shaft of the oscillating head swing in the same direction at the same angle together. The high-speed swing at a certain angle is three-dimensional oscillation; before the equipment starts, the external force rotates the knob disk 2 counterclockwise, and the reverse-thread inner-thread sleeve 13 of the knob cover fixed together with the knob disk 2 rotates and is screwed and fixed with the reverse-thread fixed shaft 15 of the oscillating head. At the same time, the gland 3 and the gland positioning indexing disk 14 are fixed together. The grinding tube adapter 4 is located between the gland 3 and the upper cover 16 of the oscillating head and is pressed tightly. The limit grooves or holes on the gland 3 and the grinding tube adapter 4 and the limit posts on the upper cover 16 of the oscillating head act together to prevent rotation; when the equipment starts, the reverse-thread fixed shaft 15 of the oscillating head starts to swing clockwise. Under the action of inertia, the originally stationary reverse-thread inner-thread sleeve 13 of the knob cover starts to rotate counterclockwise relative to the reverse-thread fixed shaft 15 of the oscillating head automatically. The retractable rotary indexing pin 1 and the knob disk 2 assembled with the reverse-thread inner-thread sleeve 13 of the knob cover also rotate counterclockwise together and automatically press the gland 3, the grinding tube adapter 4, and the gland positioning indexing disk 14 toward the oscillating head; when the retractable rotary indexing pin 1 rotates counterclockwise to a certain position, its spring pin will automatically fall into the indexing hole of the gland positioning indexing disk 14, locking the retractable rotary indexing pin 1, the knob disk 2, the reverse-thread inner-thread sleeve 13 of the knob cover, the gland 3, and the gland positioning indexing disk 14, stopping the actions and trends of continuing to rotate counterclockwise and pressing down. The high-speed swing of the oscillating head, the gland, and the adapter will cause high-frequency and high-amplitude vibrations. The vibrations are transmitted to the anti-torsion part fixing disk 21 and the oscillating head mounting base 6 in sequence through the rubber anti-torsion part 5, and then are transmitted to the equipment base 8, the equipment housing mounting chassis 11, and the equipment anchor 12 in sequence after being absorbed, buffered, and shock-absorbed by the rubber shock-absorbing balls 7.

[0025] In this embodiment, the reverse-thread self-tightening and self-locking anti-overtightening safety screw cap can rotate relative to the safety gland.

[0026] In this embodiment, a first limit groove is formed in the gland 3, a second limit groove is formed in the grinding tube adapter 4, the gland 3 is located above the grinding tube adapter 4, and a first limit post is provided on the upper cover 16 of the oscillating head. The first limit post passes through the first limit groove and the second limit groove respectively.

[0027] In this embodiment, the rubber anti-torsion part 5 is made of a rubber ring with good sealing performance.

[0028] In this embodiment, a slope is provided at the top of the eccentric shaft 20.

[0029] In this embodiment, the bottom end of the bearing fixing pin 17 extends to the inside of the top end of the eccentric shaft 20, and the outer side of the bearing fixing pin 17 is fixedly connected to the inner ring side of the oscillating head bearing 18.

[0030] In this embodiment, the top end of the rubber shock-absorbing ball 7 is fixedly connected to the bottom end of the oscillating head mounting base 6, and the bottom end of the rubber shock-absorbing ball 7 is fixedly connected to the top end of the equipment base 8.

[0031] Working principle of this embodiment: Before the equipment starts, manually or by external force, rotate the knob disk 2 counterclockwise. The assembled telescopic rotary indexing pin 1, knob disk 2, gland 3, knob cover reverse-threaded inner-threaded sleeve 13 and gland positioning indexing disk 14 move downward to the target position. When the equipment starts, the oscillating head reverse-threaded fixed shaft 15 starts to swing clockwise. Under the action of inertia, the originally stationary knob cover reverse-threaded inner-threaded sleeve 13 starts to automatically rotate counterclockwise relative to the oscillating head reverse-threaded fixed shaft 15. The telescopic rotary indexing pin 1 and knob disk 2 assembled with the knob cover reverse-threaded inner-threaded sleeve 13 also rotate counterclockwise together and automatically press the gland 3, grinding tube adapter 4 and gland positioning indexing disk 14 towards the oscillating head. During the operation of the equipment, under the action of inertia, the telescopic rotary indexing pin 1, knob disk 2, and knob cover reverse-threaded inner-threaded sleeve 13 will always maintain the tendency of counterclockwise rotation and downward pressure, avoiding the risk of loosening, falling off and being thrown out of the telescopic rotary indexing pin 1, knob disk 2, gland 3, grinding tube adapter 4, knob cover reverse-threaded inner-threaded sleeve 13 and gland positioning indexing disk 14.

[0032] When the equipment starts, the oscillating head reverse-threaded fixed shaft 15 starts to swing clockwise. Under the action of inertia, the originally stationary knob cover reverse-threaded inner-threaded sleeve 13 starts to automatically rotate counterclockwise relative to the oscillating head reverse-threaded fixed shaft 15. The telescopic rotary indexing pin 1 and knob disk 2 assembled with the knob cover reverse-threaded inner-threaded sleeve 13 also rotate counterclockwise together and automatically press the gland 3, grinding tube adapter 4, and gland positioning indexing disk 14 towards the oscillating head. The limiting groove or hole of the grinding tube adapter 4 meshes with the limiting post of the oscillating head upper cover 16 and cannot rotate. When the telescopic rotary indexing pin 1 rotates counterclockwise to a certain position, its spring pin will automatically fall into the indexing hole of the gland positioning indexing disk 14, locking the telescopic rotary indexing pin 1, knob disk 2, knob cover reverse-threaded inner-threaded sleeve 13, gland 3, and gland positioning indexing disk 14, stopping the actions and tendencies of continuous counterclockwise rotation and downward pressure, and preventing the telescopic rotary indexing pin 1, knob disk 2, and knob cover reverse-threaded inner-threaded sleeve 13 from being pressed too tightly and unable to be unscrewed after the equipment stops running.

[0033] The high-speed swinging of the oscillation head, gland, and adapter will cause high-frequency and high-amplitude vibrations. The vibrations are sequentially transmitted to the fixed disk 21, the oscillation head mounting base 6, and the rubber shock-absorbing ball 7 through the rubber anti-torsion member 5. Since the rubber shock-absorbing ball 7 is a hollow rubber material shock-absorbing ball, it can absorb some vibrations and reduce the vibration amplitude. The weakened vibrations are then sequentially transmitted to the equipment base 8, the equipment housing mounting chassis 11, and the equipment feet 12, significantly reducing the vibrations and noise during equipment operation.

[0034] The upper end of the rubber anti-torsion member 5 is sleeved on the outer edge of the lower cover 19 of the oscillation head and fixed through the anti-torsion positioning column. The inner ring of the lower end of the rubber anti-torsion member 5 is sleeved on the inner edge of the fixed disk 21 and fixed through the anti-torsion positioning column. The outer ring of the oscillation head bearing 18, the oscillation head reverse-thread fixing shaft 15, the upper cover 16 of the oscillation head, and the lower cover 19 of the oscillation head are fixed together. The rubber anti-torsion member 5 is pulled by the fixed disk 21 and cannot rotate. The lower cover 19 of the oscillation head is pulled by the rubber anti-torsion member 5 and cannot rotate freely. The outer ring of the oscillation head bearing 18 does not rotate with the inner ring of the oscillation head bearing 18. When the inner ring of the oscillation head bearing 18 rotates at a certain angle, it will drive the outer ring of the oscillation head bearing 18 to perform three-dimensional oscillation at a certain angle. The above structure enables the outer ring of the oscillation head bearing 18, the oscillation head reverse-thread fixing shaft 15, the upper cover 16 of the oscillation head, and the lower cover 19 of the oscillation head to swing in the same direction at the same angle. The outer ring of the lower end of the rubber anti-torsion member 5 is sleeved on the edge of the equipment housing to seal and isolate the sample grinding cavity and various electrical components inside the equipment housing.
