Technical Field

[0001] This utility model relates to the field of adsorption instruments, specifically providing a sample tube mounting device and an adsorption instrument. Background Technology

[0002] An adsorption analyzer is a precision analytical instrument used to determine the specific surface area of ​​materials. In practical use, because different samples need to be frequently changed for testing, operators must repeatedly disassemble and assemble the sample tubes. Currently, the sample tube assembly and disassembly process is entirely manual: before testing, the sample tube must be manually sealed and installed on the adsorption analyzer's assembly and disassembly device; after testing, it must be manually disassembled. This traditional manual assembly and disassembly method is not only cumbersome but also severely impacts testing efficiency.

[0003] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

The size of the transition zone to the side of the quick-connect insert closer to the sealing assembly gradually changes along the length direction of the adjustment hole. The second connecting structure is a guide that abuts against the transition zone. The guide can move along the transition zone when the driving member drives the quick-connect insert to move, thereby causing the sealing assembly to move between the first position and the second position; or

The first channel is close to the sealing component and its inner diameter is larger than that of the second channel, for inserting the sample tube. The inner diameter of the second channel is smaller than that of the sample tube and is used to connect with the gas inlet / outlet mechanism. The difference in inner diameter between the first channel and the second channel forms a limiting structure that restricts the insertion depth of the sample tube. Or

[0025] The first installation channel is provided with a third limiting member for limiting the insertion depth of the sample tube.

[0026] In the preferred embodiment of the above-mentioned sample tube mounting device, the sealing assembly includes a sealing plate and an elastic sealing element. The sealing plate is provided with a second mounting channel and is connected to the movable component. The elastic sealing element is located on the side of the sealing plate near the mounting joint and can be sleeved on the sample tube so that when the sealing plate moves from the second position to the first position, it cooperates with the mounting joint to squeeze the elastic sealing element, thereby pressing and sealing the sample tube.

[0027] In the preferred embodiment of the above-mentioned sample tube mounting device, the mounting joint is provided with a first insertion structure penetrated by the first mounting channel; and

[0028] The sealing plate is provided with a second insertion structure that is penetrated by the second installation channel and is inserted into and cooperates with the first insertion structure; when the first insertion structure and the second insertion structure are inserted into and cooperate, the elastic seal can be squeezed.

[0035] In a preferred embodiment of the above-mentioned sample tube mounting device, the sample tube mounting device further includes a pull rod, which connects the movable component to the sealing component.

[0036] In the preferred embodiment of the above-mentioned sample tube mounting device, the mounting joint includes a mounting block and a connector, the connector being disposed on the side of the mounting block near the sealing assembly, and having the first mounting channel thereon.

[0037] In the preferred embodiment of the above-mentioned sample tube mounting device, the number of the connectors is at least one.

[0038] This application also provides an adsorption apparatus, which includes the sample tube mounting device described in any of the above preferred technical solutions.

[0039] Those skilled in the art will understand that the sample tube installation device of this application, by setting the movable component on the mounting joint and connecting it to the sealing component, allows the sealing component to move between a first position and a second position under the drive of the movable component. When the sealing component is in the first position, it works in conjunction with the mounting joint to compress and seal the sample tube inserted in the mounting joint, ensuring the airtightness of the gas inside the sample tube. When the sealing component moves to the second position, it disengages from the mounting joint, facilitating the installation or removal of the sample tube. Furthermore, the sample tube installation device of this application eliminates the need for manual sealing of the sample tube; instead, the sealing installation of the sample tube is completed through the movable component, significantly improving operational convenience and experimental efficiency.

[0040] Furthermore, by opening a third mounting channel on the mounting joint for the rod to pass through, and connecting the two ends of the rod to the drive assembly and the sealing assembly respectively, the rod can move along the first direction under the drive of the drive assembly, thereby driving the sealing assembly to move between the first position and the second position.

[0041] Furthermore, by setting a first connecting structure on the quick-connect insert and a second connecting structure that cooperates with the first connecting structure on the rod, the quick-connect insert can drive the rod to move along the first direction when it moves under the drive of the driving component, thereby driving the sealing assembly to move between the first position and the second position.

[0042] Furthermore, by configuring the first connecting structure as an adjustment hole and a transition zone, and the second connecting structure as a guide on the rod, the adjustment hole allows the rod to pass through, enabling the quick-connect insert to move relative to the rod along the length of the adjustment hole. The transition zone corresponds to the position of the adjustment hole and abuts against it. Due to the gradual dimension design of the transition zone along the first direction, the movement of the quick-connect insert is converted into the movement of the rod along the first direction through the guide, thereby realizing the movement of the sealing assembly between the first and second positions. In addition, by configuring the first connecting structure as a transition zone with a gradual dimension along the first direction, and the second connecting structure as a connecting hole, when the quick-connect insert passes through the connecting hole, the gradual characteristic of the transition zone works in conjunction with the connecting hole to convert the movement of the quick-connect insert into the linear displacement of the rod, thereby driving the sealing assembly to move between the first and second positions.

[0043] Furthermore, by providing a guide channel on the quick-connect guide, the quick-connect insert can move along the guide channel, thereby enabling the sealing assembly to move between the first position and the second position.

[0044] Furthermore, by inserting a portion of the first connecting rod into the second connecting rod and providing an elastic element on the first connecting rod located within the second connecting rod, or by inserting a portion of the second connecting rod into the first connecting rod and providing an elastic element on the second connecting rod located within the first connecting rod; the two ends of the elastic element are respectively connected to a first limiting element on the first connecting rod and a second limiting element on the second connecting rod, such that when the first connecting rod moves away from the sealing assembly under the drive of the driving assembly, the elastic element undergoes elastic deformation, and the rebound force of the elastic element drives the second connecting rod to move the sealing assembly from the second position to the first position; when the first connecting rod moves towards the sealing assembly under the drive of the driving assembly, the elastic element undergoes elastic deformation again, and the rebound force of the elastic element drives the second connecting rod to move the sealing assembly from the second position to the first position.

[0045] Furthermore, by movably setting the first limiting member on the first connecting rod and / or movably setting the second limiting member on the second connecting rod, the initial deformation of the elastic member can be adjusted, which can prevent the spring from being over-compressed or stretched, reduce fatigue damage, and effectively adjust the impact force between the sealing assembly and the mounting joint.

[0046] Furthermore, by setting the first installation channel as an interconnected first channel and second channel, with an inner diameter difference between the first channel and the second channel, this inner diameter difference can serve as a limiting structure to restrict the insertion depth of the sample tube. This can both avoid the problem of the sample tube being inserted too deeply or too shallow due to manual operation and ensure the consistency of the positioning of sample tubes from different batches.

[0047] Furthermore, by setting the sealing assembly as a sealing plate and an elastic seal, and connecting the sealing plate to the movable assembly, when the movable assembly drives the sealing plate to move from the second position to the first position, the elastic seal sleeved on the sample tube can be squeezed under the cooperation of the sealing plate and the mounting joint, thereby achieving a tight seal on the sample tube.

[0048] Furthermore, by setting a first insertion structure on the mounting connector and a second insertion structure on the sealing plate, when the first insertion structure and the second insertion structure are inserted and engaged, the elastic sealing element can be squeezed to achieve a tight seal on the sample tube.

[0049] Furthermore, by configuring the first insertion structure as a first connecting sleeve and a first clamping member, and the second insertion structure as a second connecting sleeve that can be inserted into the first connecting sleeve, with the elastic sealing member located between the first clamping member and the second connecting sleeve, when the sealing plate moves from the second position to the first position, the first clamping member and the second connecting sleeve cooperate to compress the elastic sealing member, thereby achieving a seal on the sample tube. Additionally, by configuring the first insertion structure as a first connecting sleeve, and the second insertion structure as a second clamping member and a second connecting sleeve that can be fitted outside the first connecting sleeve, with the elastic sealing member located between the second clamping member and the first connecting sleeve, when the sealing plate moves from the second position to the first position, the second clamping member and the first connecting sleeve cooperate to compress the elastic sealing member, thereby achieving a seal on the sample tube.

[0050] Furthermore, by providing a skeleton oil seal on the inner wall of the sealing plate, the skeleton oil seal can fit tightly against the surface of the sample tube to form a radial seal, thereby ensuring that the pressure plate is in the first position and the sample tube is inserted into the second installation channel to prevent the sample tube from falling out.

[0063] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. It should be noted that in the description of this application, terms such as "upper," "lower," "inner," "bottom," and "end," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation of this application.

[0064] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "set up," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0065] Combination Figure 1-9 The sample tube mounting device of this application is described below.

[0066] like Figure 1-7 As shown, the sample tube mounting device includes a mounting connector 1, a movable component 2, and a sealing component 3. The mounting connector 1 includes a mounting block 11 and four connectors 12. The mounting block 11 has a gas passage 112 and a third mounting channel 111 extending along a first direction. The four connectors 12 are all located on one side of the mounting block 11 in the first direction. Each connector 12 has a first mounting channel 121 along the first direction that communicates with the gas passage 112. The gas passage 112 is connected to the gas inlet / outlet mechanism of the adsorption apparatus. The end of the first mounting channel 121 away from the mounting block 11 is used to insert a sample tube 7, enabling the gas inlet / outlet mechanism to perform degassing and adsorption operations on the sample in the sample tube 7. Furthermore, by providing four connectors 12, four sample tubes 7 can be inserted into the mounting connector 1 simultaneously, thereby enabling simultaneous degassing and adsorption operations on the samples in four sample tubes 7, improving experimental efficiency.

[0067] It should be noted that the first direction of this application refers to, for example, Figure 1-2 The Z-direction shown in Figure 7 includes both the positive and negative directions indicated by the arrow. The second direction refers to... Figure 1 , 3 -4 and 7 indicate the Y-direction, including both the positive and negative directions indicated by the arrows. The third direction refers to... Figure 1-2 The X direction shown in Figure 7 includes both the positive and negative directions indicated by the arrow.

[0068] In exemplary embodiments, this application does not limit the connection method between the mounting block 11 and the connector 12, as long as the connector 12 can be disposed on the mounting block 11. For example, the connector 12 is integrally formed with the mounting block 11, or the connector 12 is detachably disposed on the mounting block 11. Wherein, when the connector 12 is detachably mounted on the mounting head, a fourth limiting member 6 can be provided at the end of the connector 12 away from the mounting head, such as... Figure 1 As shown, the fourth limiting member 6 is provided with the same number of limiting holes as the connectors 12, so that these connectors 12 are limited within the limiting plate, thereby improving the stability of these connectors 12.

[0069] In exemplary embodiments, the number of connectors 12 is not fixed and can be adjusted as needed by those skilled in the art. For example, the number of connectors 12 can be one, two, three, or other numbers. Furthermore, in other preferred embodiments, the installation of connectors 12 is not mandatory and can be selected as needed by those skilled in the art. In the absence of connectors 12, a first mounting channel 121 can be directly provided on the mounting block 11, such that one end of the first mounting channel 121 is used to insert the sample tube 7, and the other end is connected to the gas passage 112.

[0070] In other preferred embodiments, the gas passage 112 is not mandatory, and those skilled in the art can choose it as needed. Without the gas passage 112, the first mounting channel 121 is directly connected to the air inlet / outlet mechanism.

[0071] See next Figure 4-6 The first installation channel 121 includes a first channel 1211 and a second channel 1212 that are interconnected. The first channel 1211 is close to the sealing assembly 3 and its inner diameter is larger than that of the second channel 1212, and is used to insert the sample tube 7. The inner diameter of the second channel 1212 is smaller than that of the sample tube 7 and is used to communicate with the gas passage 112. The difference in inner diameter between the first channel 1211 and the second channel 1212 forms a limiting structure that restricts the insertion depth of the sample tube 7, so that when the sample tube 7 is inserted into the first channel 1211, the opening of the sample tube 7 can abut against the limiting structure, thereby limiting the insertion depth of the sample tube 7.

[0072] In the exemplary embodiments, the method for limiting the insertion depth of the sample tube 7 is not fixed and can be adjusted as needed by those skilled in the art. For example, if the first installation channel 121 is a channel of equal diameter, the insertion depth of the sample tube 7 can also be limited by providing a third limiting member in the first installation channel 121, wherein the third limiting member can be an annular limiting plate.

[0073] See next Figure 3 , 7-8. The movable component 2 includes a drive component 21 and a quick-connect lifting component 22. The drive component 21 is located on the side of the mounting block 11 away from the sample tube 7. A connecting cylinder 113 is provided within the third mounting channel 111 to ensure the rod can move along the first direction. The quick-connect lifting component 22 includes a rod 221 and an elastic element. The rod 221 is inserted into the connecting cylinder 113, with both ends extending out of the connecting cylinder 113 along the first direction. One end of the rod 221 is connected to the drive component 21, and the other end is connected to the sealing component 3, allowing the sealing component 3 to move along the first direction between a first position and a second position under the action of the drive component 21 and the rod 221.

[0074] In the exemplary embodiment, the quick-connect lifting component 22 is not mandatory, and those skilled in the art can choose it as needed. Without the quick-connect lifting component, the movable component 2 or the drive component 21 can be designed as an electrically operated telescopic mechanism, the movable end of which is connected to the sealing component 3, thus enabling the sealing component 3 to move along the first direction between the first and second positions.

[0075] In the exemplary embodiment, the connection cylinder 113 is not mandatory, and those skilled in the art can choose to include it as needed. Without 113, the rod can be directly inserted into the third mounting channel extending in the first direction, ensuring that the rod moves in the first direction as well.

[0076] See next Figure 1-3 The drive assembly 21 includes a quick-connect insert 211, a drive component, and a quick-connect guide 213. The drive component is a cylinder 212. Both the quick-connect guide 213 and the cylinder 212 are mounted on the side of the mounting block 11 away from the sample tube 7 via a bracket. A guide channel 2131 is formed inside the quick-connect guide 213, extending through both ends of the quick-connect guide 213 in the second direction, allowing the quick-connect insert 211 to be movably inserted into the guide channel 2131. Both ends of the quick-connect guide 213 in the first direction are provided with communication ports 2132 communicating with the guide channel 2131. These communication ports 2132 communicate with the third mounting channel 111, allowing one end of the rod 221 to pass through the communication port 2132 and extend into the guide channel 2131.

[0077] In the exemplary embodiments, the arrangement of the quick-connect guide 213 in this application is not fixed, and those skilled in the art can adjust it according to the specific application scenario. For example, the quick-connect guide 213 may be open at both ends along the first direction, or the quick-connect guide 213 may be open at one end away from the sealing component 3, and the other end may be provided with a connecting port 2132; or the quick-connect guide 213 may not be provided with a through hole at the end away from the sealing component 3, that is, this side is a closed side.

[0078] In other preferred embodiments, the quick-connect guide 213 is not mandatory, and those skilled in the art can choose to include it as needed. Without the quick-connect guide 213, the quick-connect insert 211 is movably disposed on the side of the mounting block 11 away from the sample tube 7. This application does not limit the manner in which the quick-connect insert 211 is disposed on the side of the mounting block 11 away from the sample tube 7, as long as the quick-connect insert 211 is movably disposed on the side of the mounting block 11 away from the sample tube 7. For example, the side of the mounting block 11 away from the sample tube 7 may extend along a second direction to a slide, and the quick-connect insert 211 may be disposed within the slide via a slider.

[0079] See next Figure 7-9 The quick-connect insert 211 has a first connecting structure, and the end of the rod 221 away from the sealing assembly 3 has a second connecting structure. The first connecting structure consists of an adjustment hole 2111 and a transition area 2112. The adjustment hole 2111 is formed on the quick-connect insert 211 along a first direction, and extends along a second direction and penetrates one end of the quick-connect insert 211 in the second direction, making one end of the quick-connect insert 211 in the second direction a notched end and the other end a closed end. The closed end is connected to the movable end of the cylinder 212, and the notched end serves as an insertion end for insertion into the guide channel 2131, thereby allowing the quick-connect insert 211 to reciprocate along the second direction within the guide channel 2131 under the action of the cylinder 212. The adjustment hole 2111 is larger in the second direction than the rod 221 in the second direction, while the adjustment hole 2111 is adapted to the rod 221 in the third direction, thus facilitating the quick-connect insert 211 to pass through the rod 221 and move along the second direction within the guide channel 2131. The transition zone 2112 is located on the side of the quick-connect insert 211 away from the sealing assembly 3 and corresponds to the position of the adjustment hole 2111. The transition zone 2112 is an inclined surface, and its dimension towards the side of the quick-connect insert 2111 closest to the sealing assembly 3 gradually increases from the notched end to the closed end. The second connecting structure is a guide 223 abutting against the transition zone 2112. The guide 223 is a guide rod that can move along the transition zone 2112 when the drive member moves the quick-connect insert 211, thereby causing the sealing assembly 3 to move between the first and second positions.

[0080] It should be noted that the connecting port 2132 on the side of the quick-connect guide 213 away from the connector can also extend the guide to the connecting port 2132 when the maximum dimension of the transition zone 2112 to the side of the quick-connect plug 211 near the sealing assembly 3 is equal to the dimension of the guide channel 2131 in the first direction, ensuring that the guide can move along the transition zone. Where the connecting port 132 is not provided on the side of the quick-connect guide 13 away from the connector, the dimension of the guide channel in the first direction only needs to be not less than the sum of the dimension of the guide in the first direction and the maximum dimension of the quick-connect plug in the first direction.

[0081] It should be noted that when assembling the quick-connect lifting assembly 22 and the drive assembly 21, the first end of the rod 221 with the guide 223 is first passed through the communication port 2132 of the quick-connect guide 213, so that it extends outside the quick-connect guide 213. Then, under the action of the cylinder 212, the quick-connect insert 211 is pushed into the guide channel 2131, and then the force applied to the rod 221 is removed, so that the guide 223 extends into the guide channel 2131 and abuts against the side of the quick-connect insert 211 away from the sealing assembly 3.

[0082] In the exemplary embodiment, the structure of the adjustment hole 2111 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, both ends of the adjustment hole 2111 along the second direction are closed ends.

[0083] In the exemplary embodiments, the configuration of the first and second connecting structures is not fixed and can be adjusted as needed by those skilled in the art. For example, the first connecting structure is a transition zone 2112, which is located on the side of the quick insert 211 away from the sealing component 3, and its dimension on the side of the quick insert 211 closer to the sealing component 3 gradually changes along the length direction of the adjusting hole 2111; the second connecting structure is a connecting hole provided on the rod 221 that allows the quick insert 211 to pass through, and the inner wall of the connecting hole away from the sealing component 3 abuts against the transition zone 2112, so that when the quick insert 211 moves under the drive of the driving member, the rod 221 moves along the transition zone 2112, thereby driving the sealing component 3 to move between the first and second positions.

[0084] In the exemplary embodiments, the specific configuration of the transition region 2112 is not fixed and can be adjusted as needed by those skilled in the art. For example, the transition region 2112 may also be a curved surface. And / or, the transition region 2112 may gradually decrease in size from the notch end to the closed end.

[0085] See next Figure 3 , 7The side of quick-connect plug 211 away from mounting block 11 includes not only transition area 2112, but also first area 2113 and second area 2114. First area 2113, transition area 2112, and second area 2114 are sequentially arranged along the second direction, and transition area 2112 is connected to both first area 2113 and second area 2114. First area 2113 is near the notch end, and second area 2114 is near the closed end. The positions of the three areas correspond to the positions of adjustment holes 2111. First area 2113 and second area 2114 are both planar, while transition area 2112 is an inclined surface. Specifically, the dimension of first area 2113 in the first direction is smaller than the dimension of second area 2114 in the first direction, causing the dimension of transition area 2112 in the first direction to gradually increase from the notch end to the closed end. The guide 223 is located in the guide channel 2131. When the cylinder 212 drives the quick insert 211 to move, the guide 223 can move along the side of the quick insert 211 away from the mounting block 11 between the first zone 2113 and the second zone 2114. When the guide 223 moves along the transition zone 2112, it can drive the sealing assembly 3 to move between the first position and the second position.

[0086] In the exemplary embodiments, the configuration of the quick-connect plug 211 in this application is not fixed, and those skilled in the art can adjust it as needed. For example, the quick-connect plug 211 may only have a transition area 2112, that is, the position corresponding to the adjustment hole 2111 may only have a transition area 2112, and the guide 223 may only move along the transition area 2112 under the action of the cylinder 212.

[0087] See next Figure 2-37. Rod 221 includes a first connecting rod 2211 and a second connecting rod 2212. The second connecting rod 2212 is a sleeve structure, which is inserted into the connecting cylinder 113. Both ends of the second connecting rod 2212 extend out of the connecting cylinder 113, and one end is connected to the sealing assembly 3, while the other end allows the first connecting rod 2211 to be inserted into it. A portion of the first connecting rod 2211 is disposed within the second connecting rod 2212, and a first limiting member 22111 is provided at the end of this portion. The other portion extends out of the second connecting rod 2212 and a guide member 223 is provided at the end away from the sealing assembly 3. The first limiting member 22111 is an adjustable nut, which is threadedly connected to the first connecting rod 2211 and can move along the first connecting rod 2211 in a first direction. A second limiting member 22121 is provided at the end of the second connecting rod 2212 away from the sealing assembly 3. The second limiting member 22121 is a lock nut, which allows the first connecting rod 2211 to pass through while also being threaded to the end of the second connecting rod 2212. These two nuts also prevent the first connecting rod 2211 from coming out of the second connecting rod 2212. An elastic element, a spring 222, is provided on the first connecting rod 2211 located inside the second connecting rod 2212. The two ends of the spring 222 along the first direction are respectively connected to the lock nut and the adjustable nut. Since the adjustable nut can move along the length of the first connecting rod 2211, it can also adjust the initial compression of the spring 222. When the first connecting rod 2211 moves away from the sealing assembly under the action of the quick-connect insert 211 and the cylinder 212, the spring 222 is compressed. The rebound force of the elastic element causes the second connecting rod 2212 to move the sealing assembly 3 from the second position to the first position, thus achieving a tight seal on the sample tube 7. Conversely, when the first connecting rod 2211 moves closer to the sealing assembly 3 under the action of the quick-connect insert 211 and the cylinder 212, the elastic element is stretched. The rebound force of the elastic element causes the second connecting rod 2212 to move the sealing assembly 3 from the first position back to the second position, disengaging the sealing assembly 3 from the mounting connector 1, thereby facilitating the removal of the sample tube 7.

[0088] It should be noted that the difference between a lock nut and an adjustable nut is that the lock nut has a step formed on its inner wall, so it can only be threaded onto the end of the second connecting rod 2212 and cannot move as a whole along its length. Furthermore, the step of the lock nut is located within the cylindrical space of the second connecting rod 2212, thus allowing it to connect with the spring 222. The adjustable nut, on the other hand, can move as a whole along the length of the first connecting rod 2211.

[0089] In the exemplary embodiments, the specific configuration of the first limiting member 22111 and the second limiting member 22121 is not fixed, and those skilled in the art can adjust it as needed. For example, the first limiting member 22111 can also be a lock nut, or a limiting plate fixed on the first connecting rod 2211; and / or, the second limiting member 22121 can also be a limiting plate fixed on the inner wall of the second connecting rod 2212, or the second limiting member 22121 can also be a limiting plate threadedly connected to the inner wall of the second connecting rod 2212.

[0090] In exemplary embodiments, the configuration of the first connecting rod 2211 and the second connecting rod 2212 is not fixed and can be adjusted by those skilled in the art according to specific application scenarios. For example, the first connecting rod 2211 may be a sleeve structure, with one part of the second connecting rod 2212 disposed inside the first connecting rod 2212 and the other part extending outside the second connecting rod 2212 and connected to the sealing assembly 3; an elastic element may be provided on the second connecting rod 2212 located inside the first connecting rod 2211, with both ends of the elastic element along the first direction forming an abutment fit with the first limiting member 22111 and the second limiting member 22121 respectively. In this case, the first limiting member 22111 may be an anti-loosening nut, which is threadedly connected to the end of the first connecting rod 2211 near the sealing assembly 3, and the second limiting member 22121 may be an adjustable nut, which is connected to the second connecting rod 2212 inside the first connecting rod 2211.

[0091] In other exemplary embodiments, the provision of an elastic element is not mandatory, and those skilled in the art can choose to include it as needed. In the absence of an elastic element, the rod 221 comprises only a first connecting rod 2211 and a second connecting rod 2212, and the first connecting rod 2211 and the second connecting rod 2212 are fixedly connected to form rods 221 of equal length.

[0092] See next Figure 1-4 The sealing assembly 3 includes a sealing plate 31 and an elastic seal 32. The sealing plate 31 includes a pressure plate 311 and a connecting plate 312. The connecting plate 312 is located on the side of the pressure plate 311 near the mounting joint 1. The connecting plate 312 has four second mounting channels and through holes. The four second mounting channels correspond one-to-one with and communicate with the first mounting channel 121. Each second mounting channel passes through the pressure plate 311, and the through holes allow the end of the second connecting rod 2212 to pass through, connecting the second connecting rod 2212 to the pressure plate 311. The elastic seal 32 is a sealing ring located on the side of the connecting plate 312 near the mounting joint. It can be fitted onto the sample tube 7, so that when the pressure plate 311 moves from the second position to the first position, the connecting plate 312 cooperates with the mounting joint 1 to squeeze the sealing ring, thereby pressing and sealing the sample tube 7.

[0093] In the exemplary embodiments, the arrangement of the sealing plate 31 is not fixed and can be adjusted as needed by those skilled in the art. For example, the sealing plate 31 may also include only the pressure plate 311, which cooperates with the mounting joint 1 to compress the sealing ring.

[0094] It should be noted that the number of second installation channels is not fixed in this application, and those skilled in the art can adjust it according to the number of first installation channels 121. For example, when the number of first installation channels 121 is 1, the number of second installation channels is also 1; when the number of first installation channels 121 is 2, the number of second installation channels is also 2.

[0095] See next Figure 4-5 The connector 12 has a first insertion structure near the sealing assembly 3. The first insertion structure consists of a first connecting sleeve 122 and a first clamping member 123. The first clamping member 123 extends along the connector 12 away from the axis of the connector 12, and the first connecting sleeve 122 extends along the edge of the first clamping member 123 toward the sealing assembly 3. The connecting plate 312 has a second insertion structure near the mounting connector 1. The second insertion structure consists of a second connecting sleeve 3121, which is penetrated by a second mounting channel and extends along the connecting plate 312 toward the mounting block 11. The first connecting sleeve 122 is fitted over the second connecting sleeve 3121. The sealing ring is located inside the first connecting sleeve 122 and between the first clamping member 123 and the second connecting sleeve 3121, so that when the pressure plate 311 moves from the second position to the first position, the first clamping member 123 and the second connecting sleeve 3121 can compress the sealing ring, thereby pressing and sealing the sample tube 7.

[0096] In the exemplary embodiments, the configuration of the first and second plug-in structures is not fixed and can be adjusted as needed by those skilled in the art. For example, see... Figure 6 As shown, the first insertion structure is a first connecting sleeve 122, and the second insertion component is a second connecting sleeve 3121 and a second clamping component 3122. The second connecting sleeve 3121 extends along the connecting plate 312 toward the connector 12. The inner diameter of the second connecting sleeve 3121 is larger than the inner diameter of the second mounting channel, so that the connecting plate 312 between the inner wall of the second connecting sleeve 3121 and the second mounting channel serves as the second clamping component 3122. The second connecting sleeve 3121 is fitted over the first connecting sleeve 122, and the sealing ring is disposed inside the second connecting sleeve 3121 and located between the second clamping component 3122 and the first connecting sleeve 122. This allows the second clamping component 3122 and the first connecting sleeve 122 to compress the sealing ring when the pressure plate 311 moves from the second position to the first position, thereby pressing and sealing the sample tube 7.

[0097] In exemplary embodiments, the location of the second insertion structure is not fixed and can be adjusted as needed by those skilled in the art. For example, the second insertion structure can also be located on the pressure plate 311. When the second insertion structure is the second connecting sleeve 3121, the second connecting sleeve 3121 passes through the connecting plate 312 and is inserted into the first connecting sleeve 122, and squeezes the sealing ring inside the first connecting sleeve 122 to achieve a tight seal on the sample tube 7. When the second insertion structure is the second connecting sleeve 3121 and the second clamping member 3122, the second connecting sleeve 3121 extends along the connecting plate 312 toward the connector 12. The inner diameter of the second connecting sleeve 3121 is larger than the inner diameter of the second mounting channel, so that the pressure plate 311 between the inner wall of the second connecting sleeve 3121 and the second mounting channel serves as the second clamping member 3122. The second connecting sleeve 3121 is fitted over the first connecting sleeve 122, and the sealing ring is located inside the second connecting sleeve 3121 and between the second clamping member 3122 and the first connecting sleeve 122.

[0098] See next Figure 4-6 The sealing assembly 3 also includes four skeleton oil seals 33, each corresponding to one of the four first mounting channels 121. The inner wall of the first mounting channel 121, located at the connection between the sealing plate 31 and the connecting plate 312, forms a recessed assembly groove. The skeleton oil seals 33 are installed within this groove. When the sample tube 7 passes through the skeleton oil seal 33 and is inserted into the first mounting channel 121, the skeleton oil seal 33 can tightly adhere to the surface of the sample tube 7, forming a radial seal. This ensures that the pressure plate 311 is in the first position and that the sample tube 7 is inserted into the first mounting channel 121, preventing the sample tube 7 from falling out.

[0099] The number of skeleton oil seals 33 is consistent with the number of first mounting channels 121. That is, when there are 2 first mounting channels 121, there are 2 skeleton oil seals 33. When there are 3 first mounting channels 121, there are 3 skeleton oil seals 33.

[0100] In the exemplary embodiments, the location of the assembly groove is not fixed and can be adjusted as needed by those skilled in the art. For example, the assembly groove can also be independently disposed on the sealing plate 31 or the connecting plate 312. It should be noted that when the sealing plate 31 only includes the pressure plate 311, the assembly groove is only disposed on the pressure plate 311.

[0101] See next Figure 3 and 7The sample tube mounting device also includes a pull rod 4, which is used to connect the movable component 2 and the sealing component 3. Specifically, a connecting channel is also provided on the pressure plate 311, which passes through the connecting plate 312. A slot 3111 is provided on the inner wall of the connecting channel of the pressure plate 311. A locking block 41 that engages with the slot 3111 is provided on the outer wall of one end of the pull rod 4. The other end of the pull rod 4 passes through the first connecting channel and abuts against the end of the second connecting rod 2212. The pull rod 4 and the second connecting rod 2212 are connected by a locking member 5.

[0102] In the exemplary embodiments, the connection method between the second connecting rod 2212 and the pressure plate 311 is not fixed and can be adjusted by those skilled in the art according to the setting requirements. For example, both the second connecting rod 2212 and the pressure plate 311 are provided with threaded holes, and the outer wall of the pull rod 4 is provided with external threads, so that the pull rod 4 is threadedly connected to the first connecting rod 2211 and the pressure plate 311, thereby realizing the connection between the second connecting rod 2212 and the pressure plate 311.

[0103] In the exemplary embodiment, this application does not limit the locking element 5, as long as it can connect the pull rod 4 and the second connecting rod 2212. For example, the locking element 5 can be a bolt.

[0104] Combination Figure 1-9 This application describes the workflow for installing the sample tubes using the equipment.

[0105] When installing sample tube 7, pressure plate 311 is in the second position and sealing ring is in the initial state. Sample tube 7 is passed through the second installation channel, skeleton oil seal 33, and sealing ring, and finally inserted into the first installation channel 121 until the opening of sample tube 7 abuts against the limiting structure formed by the difference in inner diameter between the first channel 1211 and the second channel 1212.

[0106] After sample tube 7 is installed, cylinder 212 drives quick-connect insert 211 to move from the notched end to the closed end within guide channel 2131. Since guide 223 abuts against transition area 2112, the movement of quick-connect insert 211 is converted by guide 223 into movement of first connecting rod 2211 away from sealing assembly 3. At this time, elastic element is compressed, and the rebound force of elastic element causes second connecting rod 2212 to drive pressure plate 311 to move from second position to first position. During the movement, second connecting sleeve 3121 and first clamping element 123 compress the sealing ring, achieving a tight seal on sample tube 7.

[0107] After the test, cylinder 212 reverses the direction of the quick-connect insert 211, moving it from the closed end to the notched end within the guide channel 2131. This movement of the quick-connect insert 211 is then converted by guide 223 into the movement of the first connecting rod 2211 towards the sealing assembly 3. At this time, the elastic element is stretched, and the rebound force of the elastic element causes the second connecting rod 2212 to drive the pressure plate 311 from the first position back to the second position. This releases the pressure of the second connecting sleeve 3121 and the first clamping element 123 on the sealing ring, allowing the sealing ring to return to its initial state, thus facilitating the removal of the sample tube 7.
