Description

Technical Field

[0001] The utility model relates to the field of rotor structures, in particular to a rotor quick opening and closing cover structure. Background Art

[0002] The centrifuge rotor container is one of the key components of the centrifuge. Its function is to hold the samples that need to be centrifuged. The design and performance of the rotor container directly affect the working efficiency and separation effect of the centrifuge. The airtightness of the centrifuge rotor container is an important aspect in its design, especially when handling potentially infectious substances or performing high-speed centrifugation. Good airtightness ensures that the sample will not leak during the centrifugation process, and also protects the operator from possible dangerous contamination.

[0003] In the current technical context, based on the actual needs of centrifuges, the centrifuge rotor container not only needs to meet the requirements of good sealing, but also needs to be quickly locked and sealed. Because the lid needs to be opened and closed frequently, large-diameter rotor containers in the prior art often use threaded connections to lock and seal the rotor cover. Due to the sealing performance requirements, a large stroke is usually used, so that fast locking cannot be achieved. In addition, the sealing and locking reliability of threaded connections are low, and they are prone to wear, resulting in loose connections and locking failures.

[0004] In view of this, this application is hereby filed. Utility Model Content

A rotor quick opening and closing cover structure provided by an embodiment of the utility model, wherein the opening and closing cover is arranged on a locking handle mechanism, and quick sealing and opening between the opening and closing cover and the rotor mechanism are achieved through quick engagement and disengagement of the locking handle mechanism.

[0039] Example

[0040] like Figure 4-5 As shown, the embodiment of the utility model provides a rotor quick opening and closing cover structure, including a rotor mechanism 1 and an opening and closing cover 2. The upper end of the rotor mechanism 1 is open. The rotor mechanism 1 is used to accommodate samples and can rotate at high speed. The upper end of the rotor mechanism 1 is open for placing and taking out samples. The opening and closing cover 2 can be covered on the rotor mechanism 1 to cover the opening of the rotor mechanism 1 to protect the sample from contamination and maintain the sealing of the sample during centrifugation. A locking handle mechanism 3 is provided through the opening and closing cover 2 to achieve quick locking and unlocking of the opening and closing cover 2. The locking handle mechanism 3 includes a cover handle 4, a first clamping component 5 and a second clamping component 6. The cover handle 4 is provided with a first clamping component 5 and a second clamping component 6. One side is connected, the other side of the first engaging part 5 can be engaged with one side of the second engaging part 6, and the other side of the second engaging part 6 is connected to the rotor mechanism 1; the opening and closing cover 2 is sleeved on the outside of the first engaging part 5, and when the opening and closing cover 2 is covered on the rotor mechanism 1, the cover handle 4 is located on the outside of the opening and closing cover 2; when the cover handle 4 is rotated, the first engaging part 5 will be driven to rotate, and when the first engaging part 5 is rotated in the first direction, the first engaging part 5 and the second engaging part 6 can be engaged with each other and limited, and when the first engaging part 5 is rotated in the second direction, the first engaging part 5 and the second engaging part 6 can release the engagement limit; the first direction and the second direction are opposite directions.

[0041] Specifically, the lid handle 4 is the part that the operator directly operates. The operator can control the action of the clamping component by turning the handle to achieve the locking and unlocking of the opening and closing cover 2. The first clamping component 5 is connected to the lid handle 4. When the lid handle 4 rotates, it drives the first clamping component 5 to rotate. One end is connected to the lid handle 4, and the other end can interact with the second clamping component 6 to achieve clamping and unlocking. The second clamping component 6 is connected to the rotor mechanism 1. When the first clamping component 5 rotates to a specific position, it interacts with the second clamping component 6 to achieve the locking or unlocking of the opening and closing cover 2. Exemplarily, when the lid handle 4 rotates in a first direction (e.g., clockwise), the first clamping component 5 and the second clamping component 6 are mutually engaged, thereby locking the opening and closing cover 2, ensuring that the cover will not be accidentally opened during the centrifugation process. On the contrary, when the lid handle 4 rotates in a second direction (e.g., counterclockwise), the first clamping component 5 and the second clamping component 6 are released from the clamping, allowing the operator to open the opening and closing cover 2. The structure provided by the embodiment of the utility model is based on the principle of mechanical linkage. Through the user's operation of the lid handle 4, the torque is transmitted to the first engaging part 5, thereby achieving engagement or unlocking with the second engaging part 6. This structure simplifies the complexity of the traditional threaded fastening method and improves the operating efficiency.

[0042] For example, Figure 1-3As shown, the first engaging component 5 or the second engaging component 6 includes a hollow sleeve member 8, and a plurality of spiral grooves 9 are arranged on the wall of the hollow sleeve member 8. The second engaging component 6 or the first engaging component 5 includes an axial member 10, and a plurality of pin structures 11 are radially extended from the axial member 10; the outer diameter of the axial member 10 is less than or equal to the inner diameter of the hollow sleeve member 8 to ensure that the axial member 10 and the hollow sleeve member 8 can be interlocked with each other, and the sum of the radial extension distance of the pin structure 11 and the radius of the axial member 10 is greater than the inner radius of the hollow sleeve member 8 to limit the pin structure 11 from passing through the hollow sleeve member 8; the spiral groove 9 includes an open end 12 and a sealing end 13, and the spiral groove 9 is a spiral channel inside the hollow sleeve member 8, allowing the pin structure 11 to move therein. When the first engaging member 5 rotates in the first direction (e.g., clockwise), the single pin structure 11 can enter the single spiral groove 9 from the open end 12, and is in a locked state when it moves to the sealed end 13, at which time the hollow sleeve member 8 is sleeved on the outside of the shaft member 10; when the first engaging member 5 rotates in the second direction (e.g., counterclockwise), the single pin structure 11 can move from the sealed end 13 to the open end 12, until it is in an unlocked state when it is separated from the single spiral groove 9. Specifically, when the first engaging member 5 rotates in the first direction (e.g., clockwise), the pin structure 11 enters the groove from the open end 12 of the spiral groove 9, and as it rotates, the pin structure 11 moves to the sealed end 13 of the spiral groove 9. At this time, due to the matching of the radial dimensions, the pin structure 11 interacts with the sealed end 13 of the spiral groove 9 to achieve a locked state. This structure enables the operator to quickly lock and unlock the engaging member through a simple rotation action, thereby improving the operating efficiency. In the locked state, the interaction between the pin structure 11 and the sealing end 13 of the spiral groove 9 provides reliable locking, which increases safety during use. The size setting of the shaft member 10 and the hollow sleeve member 8 ensures the compactness of the overall structure, which may make the mechanism suitable for application scenarios with limited space.

[0043] By adopting the structure provided by the embodiment of the utility model, the traditional large-diameter opening and closing cover 2 is locked by thread locking and converted to a small-size knob locking, and the traditional threaded connection is converted into a spiral groove 9 and a pin structure 11, and the sealing end 13 adopts a card slot. This locking structure depends on the structure of the parts themselves, and there is no locking failure due to thread wear, vibration and other factors. In terms of operation, the smaller-size knob is closer to ergonomics, saves more manpower and time, and improves work efficiency. It should be noted that this structure can be used in various types of containers that need to be sealed in the traditional way, especially in situations where the threaded connection is unreliable and easy to loosen due to vibration, equipment operation, etc. Back to the embodiment of the utility model, it should also be explained that the first clamping component 5 can be driven, the second clamping component 6 is fixedly connected to the rotor mechanism 1 and cannot rotate, and the hollow sleeve member 8 can be the structure of the first clamping component 5 or the second clamping component 6. There is no limitation here, as long as the purpose of matching the hollow sleeve member 8 and the shaft member 10 can be achieved. In the embodiment of the utility model, the spiral groove 9 is arranged on the first clamping component 5, and the pin structure 11 is arranged on the second clamping component 6. In other embodiments, the spiral groove 9 can also be arranged on the second clamping component 6, and the pin structure 11 can also be arranged on the first clamping component 5.

[0044] As a preferred embodiment of the utility model, two spiral grooves 9 are provided, and two pin structures 11 are provided, and the two pin structures 11 are arranged axially symmetrically along the axis of the shaft core member 10. The design of the double spiral groove 9 and the double pin provides a double locking mechanism, which provides higher stability and safety when engaging. When the first engaging part 5 rotates in the first direction, the two pin structures 11 enter the groove from the opening ends 12 of the respective spiral grooves 9, and achieve locking when moving to the sealing end 13. Due to the axially symmetrical arrangement, the engaging part in this locked state has good balance. When the first engaging part 5 rotates in the second direction, the two pin structures 11 start to move from the sealing ends 13 of the spiral grooves 9 where they are located, until they reach the opening end 12 and disengage from the spiral grooves 9, thereby achieving unlocking. Of course, in other embodiments, only one spiral groove 9 and one pin structure 11 can be provided, or three or four can be provided. The specific arrangement can be based on actual conditions, and there is no restriction here, as long as the purpose of stable and rapid engagement and unlocking can be achieved.

[0045] Furthermore, a plurality of first bolt holes 14 are provided on the rotor mechanism 1, a mounting tray 15 is provided at one end of the shaft member 10, a plurality of second bolt holes 16 are provided on the mounting tray 15, and a single first bolt hole 14 and a single second bolt hole 16 can be fixedly connected by a bolt rod. The mounting tray 15 and the shaft member 10 can be integrally arranged or detachably arranged, and there is no restriction here, as long as the purpose of stable connection can be achieved. For the convenience of understanding, the mounting tray 15 provided in the embodiment of the utility model is integrally arranged with the shaft member 10, and a single first bolt hole 14 and a single second bolt hole 16 can be fixedly connected by a bolt rod. The bolt rod is usually threaded and can be screwed into the bolt hole and tightened. The tightening of the bolt rod can ensure a rigid connection between the rotor mechanism 1 and the shaft member 10, and prevent relative movement or axial movement of the shaft member 10 during the operation of the centrifuge. This structure ensures that the connection between the shaft member 10 and the rotor mechanism 1 is not only firm but also detachable. When the shaft member 10 is damaged, it is convenient to disassemble and replace it, and has high flexibility.

[0046] In order to improve the connection stability between the opening and closing cover 2 and the first engaging part 5, an outwardly convex step structure 17 can be provided on the first engaging part 5, a mounting groove 18 is formed between the step structure 17 and the lid handle 4, a through hole 19 is provided on the opening and closing cover 2, and the mounting groove 18 is arranged on the inner side of the through hole 19. Specifically, the mounting groove 18 is a groove for positioning and fixing the opening and closing cover 2, and the through hole 19 cooperates with the groove to realize the stable installation of the opening and closing cover 2 and the first engaging part 5. Through the design of the mounting groove 18 and the step structure 17, the connection stability between the opening and closing cover 2 and the first engaging part 5 is improved, and the displacement or looseness caused by vibration or impact during the operation of the centrifuge is reduced. Of course, a polytetrafluoroethylene gasket 20 can also be provided between the opening and closing cover 2 and the lid handle 4. The polytetrafluoroethylene gasket 20 can effectively prevent liquid and gas leakage and maintain the sealed environment inside the centrifuge. At the same time, the use of the gasket helps to reduce the direct contact between the lid handle 4 and the opening and closing cover 2, thereby reducing wear.

[0047] In order to improve the sealing performance between the opening and closing cover 2 and the rotor mechanism 1, the embodiment of the utility model is provided with a sealing groove on the outer edge of the opening and closing cover 2, and a sealing ring 21 is provided in the sealing groove. The sealing ring 21 is embedded in the sealing groove and matched with the corresponding part of the rotor mechanism 1 to form a sealing interface, thereby improving the sealing performance of the entire centrifugal process. In order to improve the connection stability and flexibility between the lid handle 4 and the first clamping part 5, a flange mechanism 22 can be sleeved on the first clamping part 5, and the flange mechanism 22 is connected to the lid handle 4 through a screw mechanism, and the flange mechanism 22 is riveted to the first clamping part 5. Of course, in other embodiments, the connection structure part is limited as long as the purpose of sufficient connection stability can be achieved. In general, the structure of the embodiment of the utility model can achieve rapid locking, and the spiral groove 9 is combined with the pin structure 11, so that the locking is more reliable. At the same time, the operation is more ergonomic than the knob of the end cover with a larger diameter, which is more convenient and fast, and saves time and effort.

[0048] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
