Description

Technical Field

[0001] The invention relates to the technical field of hanging cups, and in particular provides a hanging cup assembly. Background Art

[0002] In the field of biochemical research technology, centrifuges are needed to centrifuge samples. Existing centrifuges need to use rotors as carriers when separating samples. Existing rotors are divided into angle rotors and horizontal rotors. Angle rotors can achieve sealing through their own structure; horizontal rotors need to hang hanging cups when separating samples. Some special samples are harmful to the human body. In order to protect operators, sealed hanging cups or rotors are needed to improve safety.

[0003] The current airtight hanging cup technology mainly achieves sealing by adding a sealing cover to the hanging cup. The existing sealing structure mainly uses a threaded cover and a rotating mechanism to achieve a compressed closed seal.

[0004] The biosafety sealing cover structure on the existing centrifuge includes a hanging basket and a cover body that matches the hanging basket; the hanging basket is provided with an upper port as a sealing surface, and bosses are provided on both sides; rotatable inverted U-shaped handles are provided on both sides of the cover body, and a sealing ring that matches the upper port of the hanging basket is provided on the lower port; both ends of the handle are provided with a slot that can match the boss on the hanging basket. The seal between the sealing cover and the hanging cup is mainly achieved by rotating the handle on the sealing cover around a point on the sealing cover so that the lower port of the handle is stuck in the groove of the hanging cup. Since the lower port is a plastic part, long-term friction and extrusion with the metal hanging cup boss will cause the lower port to wear too quickly. As a result, the service life of the sealing cover structure is relatively low, and the cost of replacing the sealing cover is high.

[0005] Therefore, a new hanging cup assembly is urgently needed to solve the above technical problems Summary of the invention

[0006] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing hanging cup assembly has a short service life and the cost of replacing the sealing cover is high.

[0007] In a first aspect, the present invention provides a hanging cup assembly, the hanging cup assembly comprising:

[0008] The hanging cup body has a first connecting portion disposed on the outer edge of the top thereof;

[0009] A hanging cup cover, the outer edge of which is provided with a second connection portion corresponding to the first connection portion;

[0010] The fixing assembly comprises a connecting piece and a limiting piece, wherein the connecting piece is used to connect the first connecting part and the second connecting part, and the limiting piece is used to limit the connecting piece so that the connecting piece fixes the hanging cup body and the hanging cup cover.

[0011] In a specific embodiment of the above hanging cup assembly, a first limiting portion is provided on the connecting member, and a second limiting portion is provided on the limiting member;

[0012] The first limiting portion and the second limiting portion cooperate with each other, so that the limiting member can limit the position of the connecting member, so that the connecting member is fixedly connected to the first connecting portion and the second connecting portion;

[0013] After the first limiting portion and the second limiting portion are released from engagement, the connecting member can release the locking of the first connecting portion and the second connecting portion.

[0014] In a specific embodiment of the above-mentioned hanging cup assembly, one of the first limiting portion and the second limiting portion is a limiting protrusion, and the other is a limiting groove.

[0015] In a specific embodiment of the above-mentioned hanging cup assembly, the limiting member includes a limiting spring sheet, and the second limiting portion is arranged on the limiting spring sheet.

[0016] In a specific implementation of the above-mentioned hanging cup assembly, two first limiting portions are arranged on the connecting member, and the limiting member includes two limiting spring pieces.

[0017] In a specific embodiment of the above hanging cup assembly, the connecting member is arranged on the second connecting portion and is movably connected to the second connecting portion;

[0018] The limiting member is arranged on the first connection part. After the hanging cup cover is buckled on the hanging cup body, rotating the connecting member can make the first limiting part cooperate with the second limiting part or release the cooperation between the first limiting part and the second limiting part.

[0019] In a specific embodiment of the above-mentioned hanging cup assembly, the fixing assembly further includes a positioning member, which is arranged on the connecting member and is used to limit the connecting member on the second connecting portion.

[0020] In a specific embodiment of the above hanging cup assembly, one end of the connecting member that cooperates with the limiting member is a pointed end.

[0021] In a specific embodiment of the above hanging cup assembly, the hanging cup body is provided with a plurality of the first connection parts along its circumferential spaced ring, and the hanging cup cover is provided with a plurality of second connection parts corresponding to the first connection parts.

[0022] In a specific embodiment of the above hanging cup assembly, the hanging cup assembly further includes a sealing ring, and the sealing ring is arranged between the hanging cup cover and the hanging cup body.

[0023] When adopting the above technical scheme, the hanging cup assembly of the present invention includes a hanging cup body, a hanging cup cover and a fixing assembly; a first connecting portion is provided at the outer edge of the top of the hanging cup body; a second connecting portion corresponding to the first connecting portion is provided at the outer edge of the hanging cup cover; the fixing assembly includes a connecting piece and a limiting piece, the connecting piece is used to connect the first connecting piece and the second connecting piece, and the limiting piece is used to limit the connecting piece so that the connecting piece fixes the hanging cup body and the hanging cup cover; the hanging cup assembly can be placed on a centrifuge to separate samples.

[0024] Furthermore, a first limiting portion is provided on the connecting member, and a second limiting portion is provided on the limiting member; the first limiting portion and the second limiting portion cooperate to enable the limiting member to limit the connecting member, so that the connecting member is fixedly connected to the first connecting portion and the second connecting portion; after the first limiting portion and the second limiting portion are released from cooperation, the connecting member can release the lock on the first connecting portion and the second connecting portion. Specifically, one of the first limiting portion and the second limiting portion is a limiting protrusion, and the other is a limiting groove. The limiting protrusion and the limiting groove cooperate to limit the connecting member and the limiting member, so that the two cooperate to lock the first connecting portion and the second connecting portion, thereby connecting the hanging cup body to the hanging cup cover. Since the connection is made by a snap-on method instead of a threaded connection, there is no friction between the hanging cup cover and the hanging cup body, and the service life of the hanging cup assembly will not be reduced due to frequent connections, thereby ensuring the service life of the hanging cup assembly and reducing the use cost of the hanging cup assembly.

[0025] In addition, two first limiting parts are arranged on the connecting member, and the limiting part includes two limiting spring plates; the two first limiting parts are symmetrically arranged, and the two limiting spring plates are respectively located on both sides of the connecting member. Since the two limiting spring plates are respectively located on both sides of the connecting member, after the first limiting part cooperates with the second limiting part, if the hanging cup cover tends to separate from the hanging cup body, the clamping force of the two limiting spring plates on the connecting member will increase, so that the connecting member cannot separate from the limiting part, that is, the hanging cup cover can be firmly fixed on the hanging cup body.

[0026] Furthermore, a positioning groove is provided on the connecting rod, and the positioning member is a retaining spring. After the connecting member is inserted into the second connecting part, the retaining spring is embedded in the positioning groove, and the connecting member is limited to the second connecting part, and the connecting member can be rotated relative to the second connecting part, but cannot move axially. Since the connecting member cannot move axially relative to the second connecting part, when the hanging cup cover is fastened, the connecting rod can pass through the first connecting part and cooperate with the limiting member, and after the hanging cup cover is removed, the connecting member cannot fall off from the second connecting part, which can ensure that the connecting member is not easily lost; furthermore, when the hanging cup cover is fastened, the connecting member can be directly matched with the limiting member, which is convenient for connection; the surface area of ​​the hanging cup cover relative to the connecting member is large, and when fastened, the connecting member can be inserted between the two limiting springs more easily.

[0027] One end of the connecting piece that matches the limiting piece is a tip; that is, the free end of the connecting rod is a tip, so that when the hanging cup cover is buckled, the tip can open the two limiting springs, so that the part where the first limiting part is set moves to between the second limiting parts of the two limiting springs; so that the first limiting part and the second limiting part can cooperate with each other to lock the connecting piece, so as to lock the hanging cup cover and the hanging cup body. Furthermore, when removing the hanging cup cover, the two limiting springs clamp the tip, so that the hanging cup cover can be easily removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The biosafety sealing cover structure on the existing centrifuge includes a hanging basket and a cover body that cooperates with the hanging basket; the hanging basket is provided with an upper port as a sealing surface, and bosses are provided on both sides; rotatable inverted U-shaped handles are provided on both sides of the cover body, and a sealing ring that cooperates with the upper port of the hanging basket is provided on the lower port; and slots that can cooperate with the upper boss of the hanging basket are provided at both ends of the handle. The sealing between the sealing cover and the hanging cup is mainly achieved by rotating the handle on the sealing cover around a point on the sealing cover so that the lower port of the handle is stuck in the groove of the hanging cup. Since the lower port is a plastic part, long-term friction and extrusion with the metal hanging cup boss will cause the lower port to wear too quickly. As a result, the service life of the sealing cover structure is short and the replacement cost is high; as a result, the use cost of the hanging cup is high.

[0039] In order to solve the above technical problems, Figure 1-4 As shown, the present invention discloses a hanging cup assembly, which includes a hanging cup body 2, a hanging cup cover 1 and a fixing assembly.

[0040] The outer edge of the top of the hanging cup body 2 is provided with a first connecting portion; that is, the first connecting portion is provided outside the cup mouth of the hanging cup body 2, wherein the first connecting portion is specifically a connecting ear. The connecting ear is an arc-shaped plate, and is smoothly connected to the hanging cup body 2. Specifically, the direct connection between the connecting ear and the hanging cup body 2 is arc-shaped, which can make the connection between the connecting ear and the hanging cup body 2 more reliable, and reduce the edges and corners, and reduce the resistance when the hanging cup assembly rotates. In the present embodiment, the connecting ear and the hanging cup body 2 are integrally formed, and the integral forming can ensure the connection strength between the two. In other embodiments, the connecting ear can also be fixed on the hanging cup body 2 by welding.

[0041] The outer edge of the hanging cup cover 1 is provided with a second connecting portion corresponding to the first connecting portion; wherein the second connecting portion is also a connecting ear, and is smoothly connected to the hanging cup cover 1. Specifically, the direct connection between the connecting ear and the hanging cup cover 1 is arc-shaped, which can make the connection between the connecting ear and the hanging cup cover 1 more reliable, and reduce the edges and corners, and reduce the resistance when the hanging cup assembly rotates. In this embodiment, the connecting ear and the hanging cup cover 1 are integrally formed, and the integral forming can ensure the connection strength between the two. In other embodiments, the connecting ear can also be fixed to the hanging cup cover 1 by welding.

[0042] like Figure 4As shown, the hanging cup cover 1 can be buckled on the hanging cup body 2 to cover the hanging cup body 2. The hanging cup assembly also includes a sealing ring 6, which is arranged between the hanging cup cover 1 and the hanging cup body 2. Specifically, an annular groove is provided on the hanging cup cover 1, and the sealing ring 6 is embedded in the annular groove. The sealing ring 6 and the annular groove have an interference fit, so that the sealing ring 6 cannot fall off from the annular groove by itself, and the sealing ring 6 and the annular groove can be sealed. It should be noted that the connection method between the sealing ring 6 and the annular groove is that although the two are interference fit in this embodiment, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art can also choose to connect the sealing ring 6 to the annular groove by bonding, which can also fix the sealing ring 6 on the hanging cup cover 1, and can make the sealing ring 6 and the hanging cup cover 1 sealed. This does not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0043] The sealing ring 6 is partially protruded from the hanging cup cover 1 , so that when the hanging cup cover 1 and the hanging cup body 2 are buckled together, the sealing ring 6 can abut against the top surface of the hanging cup body 2 to achieve a sealed connection between the hanging cup cover 1 and the hanging cup body 2 .

[0044] The hanging cup body 2 is provided with a plurality of first connecting parts along its circumferential spacing ring, and the hanging cup cover 1 is provided with a plurality of second connecting parts corresponding to the first connecting parts; by providing a plurality of first connecting parts and a plurality of second connecting parts, the hanging cup cover 1 and the hanging cup body 2 can be subjected to force at multiple circumferential positions, the stability of the connection can be ensured, and the hanging cup cover 1 and the hanging cup body 2 are not easily damaged. Preferably, in the present embodiment, two first connecting parts are symmetrically provided on the hanging cup body 2, and correspondingly, two second connecting parts are symmetrically provided on the hanging cup cover 1. Regarding the number of the first connecting parts and the second connecting parts, it should be noted that, although there are two in the present embodiment, this is not a limitation of the present invention. In other embodiments, those skilled in the art may choose to provide three or more first connecting parts on the hanging cup body 2, and correspondingly, provide three or more second connecting parts on the hanging cup cover 1, which can make the hanging cup body 2 firmly connected to the hanging cup cover 1. This does not deviate from the basic principle of the present invention and will fall within the scope of protection of the present invention.

[0045] Among them, Figure 1-4As shown, the fixing assembly includes a connecting member 3 and a limiting member 4, the connecting member 3 is used to connect the first connecting part and the second connecting part, and the limiting member 4 is used to limit the connecting member 3 so that the connecting member 3 fixes the hanging cup body 2 and the hanging cup cover 1. Specifically, a first limiting portion 31 is provided on the connecting member 3, and a second limiting portion 41 is provided on the limiting member 4. The first limiting portion 31 and the second limiting portion 41 cooperate to enable the limiting member 4 to limit the connecting member 3 so that the connecting member 3 is fixedly connected to the first connecting part and the second connecting part. After the first limiting portion 31 and the second limiting portion 41 are released from cooperation, the connecting member 3 can release the lock on the first connecting part and the second connecting part.

[0046] More specifically, one of the first limiting portion 31 and the second limiting portion 41 is a limiting protrusion and the other is a limiting groove. In this embodiment, the first limiting portion 31 is a limiting groove and the second limiting portion 41 is a limiting protrusion. The limiting member 4 includes a limiting spring sheet, which has a certain elasticity and can make the free end of the limiting spring sheet abut against the connecting member 3. The second limiting portion 41 is arranged on the limiting spring sheet, specifically at the free end of the limiting spring sheet. Furthermore, the free end of the limiting spring sheet is bent to form a limiting protrusion. The limiting spring sheet can make the limiting protrusion embedded in the limiting groove, specifically refer to Figure 2 , so that the two can cooperate with each other to lock the connector 3. Regarding the positions of the limiting groove and the limiting protrusion, it should be noted that although the limiting groove is set on the connector 3 and the limiting protrusion is set on the limiting spring sheet in this embodiment, this is not a limitation of the present invention. In other embodiments, those skilled in the art can also set the limiting groove (the limiting groove can be a groove or a through hole) on the limiting spring sheet, and the limiting protrusion on the connector 3. The limiting spring sheet can make the limiting groove buckle on the limiting protrusion to achieve the locking of the connector 3. This does not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0047] The connecting member 3 is provided with two first limiting portions 31, and the limiting member 4 includes two limiting springs. The two first limiting portions 31 are symmetrically arranged, and the two limiting springs are respectively located on both sides of the connecting member 3, so that the two second limiting portions 41 can cooperate with the two first limiting portions 31 to achieve locking of the connecting member 3.

[0048] The connecting member 3 is arranged on the second connecting part and is movably connected with the second connecting part; the connecting member 3 includes an integrally formed limiting cap and a connecting rod. A through hole is arranged on the second connecting part, and the connecting rod is passed through the through hole and can rotate relative to the second connecting part. The limiting cap is located on the side of the second connecting part away from the first connecting part, that is, located above the second connecting part. A rotating handle 32 is arranged on the limiting cap, and the connecting member 3 can be rotated by rotating the handle 32.

[0049] The limiting member 4 is arranged on the first connecting part, and the limiting member 4 is specifically located on the side of the first connecting part away from the second connecting part, and is fixed to the first connecting part by screws. The limiting member 4 is in an "Ω" shape as a whole, and can clamp the connecting member 3 in the middle. A through hole is arranged on the first connecting part, and a avoidance hole corresponding to the through hole of the first connecting part is arranged on the limiting member 4, so that the connecting member 3 can cooperate with the limiting spring sheet for limiting. Since the two limiting spring sheets are respectively located on both sides of the connecting member 3, after the first limiting portion 31 cooperates with the second limiting portion 41, if the hanging cup cover 1 tends to be separated from the hanging cup body 2, the clamping force of the two limiting spring sheets on the connecting member 3 will increase, so that the connecting member 3 cannot be separated from the limiting member 4, that is, the hanging cup cover 1 can be firmly fixed on the hanging cup body 2. In addition, the sealing ring 6 protrudes from the hanging cup cover 1. When the hanging cup cover 1 is pressed onto the hanging cup body 2, the sealing ring 6 is elastic and can tighten the connecting piece 3 in the vertical direction, cooperate with the groove on the connecting piece 3, prevent the connecting piece 3 from rotating, and play a sealing role.

[0050] After the hanging cup cover 1 is buckled, the connecting member 3 passes through the through hole on the first connecting part and the avoidance hole on the limiting member 4, so that the connecting rod is inserted between the two limiting spring sheets. Figure 1 Rotating the rotary handle 32 can rotate the connecting rod so that the first limiting portion 31 cooperates with the second limiting portion 41, specifically referring to Figure 2 , to connect the first connection portion and the second connection portion; or release the first limit portion 31 and the second limit portion 41, for specific reference Figure 1 , so that the first connection part can be separated from the second connection part. Specifically, the rotating handle 32 is rotated to rotate the connecting rod so that the limiting groove rotates relative to the limiting protrusion. When the limiting groove rotates to the limiting protrusion, the limiting protrusion can be embedded in the limiting groove under the drive of the limiting spring sheet to achieve the locking of the axial movement of the connecting member 3, thereby achieving the fixed connection between the hanging cup cover 1 and the hanging cup body 2; when the connecting member 3 is rotated to make the limiting groove separate from the limiting protrusion, the locking of the axial movement of the connecting member 3 is released, so that the hanging cup cover 1 can be removed from the hanging cup body 2, so as to place the sample in the hanging cup body 2 or take the sample out of the hanging cup body 2.

[0051] Please continue to refer to Figure 4, the fixing assembly also includes a positioning member 5, which is arranged on the connecting member 3 and is used to limit the connecting member 3 on the second connecting part. Specifically, a positioning groove is arranged on the connecting rod, and the positioning member 5 is a retaining spring. After the connecting member 3 is inserted into the second connecting part, the retaining spring is embedded in the positioning groove, the connecting member 3 is limited to the second connecting part, and the connecting member 3 can be rotated relative to the second connecting part, but it cannot move axially. Since the connecting member 3 cannot move axially relative to the second connecting part, when the hanging cup cover 1 is buckled, the connecting rod can pass through the first connecting part and cooperate with the limiting member 4; after the hanging cup cover 1 is removed, the connecting member 3 cannot fall off from the second connecting part, which can ensure that the connecting member 3 is not easy to lose; furthermore, when the hanging cup cover 1 is buckled, the connecting member 3 can be directly matched with the limiting member 4, which is convenient for connection; the surface area of ​​the hanging cup cover 1 relative to the connecting member 3 is large, and when buckled, the connecting member 3 can be inserted between the two limiting springs more easily.

[0052] Specific reference Figure 1-4 , one end of the connecting member 3 that matches with the limiting member 4 is a tip; that is, the free end of the connecting rod is a tip, so that when the hanging cup cover 1 is buckled, the tip can open the two limiting springs, so that the part where the first limiting part 31 is set moves to between the second limiting parts 41 of the two limiting springs; so that the first limiting part 31 and the second limiting part 41 can cooperate with each other to lock the connecting member 3, so as to lock the hanging cup cover 1 and the hanging cup body 2. Furthermore, when removing the hanging cup cover 1, the two limiting springs clamp the tip, so that the hanging cup cover 1 can be easily removed.

[0053] When the sample needs to be centrifuged, the sample is placed in the hanging cup body 2; then the hanging cup cover 1 is buckled on the hanging cup body 2. During the buckling process, the connecting rod is aligned with the through hole on the first connecting part, so that the connecting rod can pass through the through hole and move to the position limiting member 4, and the rotating handle 32 is rotated to rotate the position limiting groove to the position limiting protrusion, and the position limiting protrusion is embedded in the position limiting groove, so that the connecting member 3 and the position limiting member 4 cooperate to lock the first connecting part and the second connecting part, thereby fixing the hanging cup cover 1 on the hanging cup body 2.

[0054] After the centrifugal separation of the sample is completed, the hanging cup is removed. The rotating handle 32 is turned to disengage the limiting groove from the limiting protrusion, and then the limiting protrusion is abutted against the side wall of the connecting rod to release the limit of the connecting member 3, so that the connecting member 3 can be separated from the limiting member 4, so that the second connecting part can be separated from the first connecting part, so that the hanging cup cover 1 can be removed; then the sample in the hanging cup body 2 is taken out.

[0055] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
