[0031] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present application with reference to the drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0032] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0033] In addition, if the term "and / or" appears, "and / or" is merely a description of the relationship between associated objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this text generally indicates an "or" relationship between the associated objects before and after it. If terms such as "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, four, five, etc., unless otherwise specifically and clearly defined.

[0034] In the present application, unless otherwise clearly specified and limited, if terms such as "install", "connect", "join", "fix", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0035] In this application, unless otherwise clearly defined and limited, when a first feature is described as being "on" or "under" a second feature or similar descriptions, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0037] Please refer to Figure 1 and Figure 2 As shown in [figures not provided], a reagent tray 100 provided by an embodiment of the present application includes a base assembly 10 and a tray body 30. The base assembly 10 has a sliding guide structure 11, and the tray body 30 has a placement groove 31 and a sliding fit structure 32. The placement groove 31 is used to place solution bottles, and the sliding fit structure 32 is configured to be able to slide fit with the sliding guide structure 11. The tray body 30 is slidably mounted on the base assembly 10 through the sliding fit structure 32.

[0038] It can be understood that the reagent tray 100 can be used in a detection device and is used to hold solution bottles, and the solution bottles can be specifically placed in the placement groove 31. The tray body 30 may have at least two placement grooves 31 to distinguish and place different solution bottles. Specifically, the placement grooves 31 of the tray body 30 can be divided into at least two specifications to be able to place solution bottles of different specifications. The solution bottles are used to hold various solutions such as different reaction reagents and cleaning liquids, so that the detection device can automatically suck the solutions held in the solution bottles to achieve functions such as rapid sample addition and cleaning. In addition, a distinguishing mark may be provided beside the placement groove 31 to distinguish the placement groove 31 and the solution bottles therein.

[0039] The tray body 30 is slidably mounted on the base assembly 10 along the sliding direction. The tray body 30 has a pushed-in state and a pulled-out state, and switches between the pushed-in state and the pulled-out state by sliding relative to the base assembly 10. During use, the base assembly 10 can be placed on a fixed tabletop, and by pushing and pulling the tray body 30, it can be driven to move relative to the base assembly 10 so as to be pushed into and pulled out of the detection device. When the tray body 30 is in the pushed-in state, functions such as sampling, sample addition, and cleaning can be performed. When the tray body 30 is in the pulled-out state, operations such as placing and removing the solution bottle can be performed.

[0040] For the above reagent tray 100, the tray body 30 and the base assembly 10 are slidably engaged through the sliding guide structure 11 and the sliding fit structure 32, forming a push-pull structure that facilitates the placement and removal of the solution bottle. When it is necessary to place and remove the solution bottle, the reagent tray 100 is pulled out so that the solution bottle can be less interfered by the detection device and be smoothly and accurately placed in the placement groove 31 of the tray body 30, ensuring the reliable progress of the experiment.

[0041] Please refer to Figure 3 and Figure 4 In some embodiments, one of the sliding guide structure 11 and the sliding fit structure 32 is a guide rail, and the other is a sliding groove that can be slidably engaged with the guide rail.

[0042] It can be understood that the extending direction of the sliding groove is the same as the longitudinal direction of the guide rail (such as Figure 1 the X direction shown in), that is, the sliding direction of the tray body 30. The guide rail has an outer end 111 and an inner end 113 in the longitudinal direction. When pushing the tray body 30, the tray body 30 slides along the direction from the outer end 111 towards the inner end 113, switching from the pulled-out state to the pushed-in state. On the contrary, when pulling the tray body 30, the tray body 30 slides along the direction from the inner end 113 towards the outer end 111, switching from the pushed-in state to the pulled-out state. In some other embodiments, one of the sliding guide structure 11 and the sliding fit structure 32 can also be a slider, a roller, a ball, etc., and the other is a slideway, a roller groove, a ball groove, etc. that cooperate with the slider, roller and other structures, which are not specifically limited herein.

[0043] In this way, the tray body 30 and the base assembly 10 can form a sliding fit through the guide rail and the sliding groove, and the sliding direction of the tray body 30 relative to the base assembly 10 can be set by correspondingly configuring the direction of the guide rail and the sliding groove.

[0044] In some embodiments, at least one of the surface of the tray body 30 in contact with the guide rail and the surface of the guide rail in contact with the tray body 30 has a groove 34 and / or a hollow structure (not shown in the figure).

[0045] Among them, the groove 34 is formed by the concave of the surface of the tray body 30, and the hollow structure is a through hole formed by the tray body 30. The hollow structure can make the contact surface between part of the tray body 30 and the guide rail missing. Specifically, the bottom surface of the tray body 30 in contact with the guide rail is constructed with a groove 34, and the groove 34 can be arranged to extend along the sliding direction.

[0046] In this way, the groove 34 and the hollow structure can reduce the contact area between the tray body 30 and the guide rail. If the surface of the tray body 30 in contact with the guide rail becomes rough due to wear, corrosion or attachment of sundries, reducing the contact area between the two can reduce the sliding resistance increased due to the increase in the surface roughness of the contact surface, ensuring the smoothness of the pulling.

[0047] In some embodiments, at least one side of the guide rail in the width direction (such as Figure 1 the Y direction shown in the figure) has a concavo-convex structure.

[0048] It can be understood that the sliding groove is correspondingly shaped to fit the guide rail. In other words, at least one side of the two in the width direction meshes with each other, and the guide rail is inserted into the sliding groove along its longitudinal direction, so that the tray body 30 can be pulled on the guide rail.

[0049] Specifically, the cross-section of the guide rail perpendicular to its longitudinal direction can be in the shape of a "T" or an "I", etc.

[0050] In this way, the guide rail can be more stably fitted with the sliding groove, preventing the two from separating from each other along the height direction (such as Figure 2 the Z direction shown in the figure).

[0051] In some embodiments, one end of the guide rail is narrowed in the width direction of the guide rail and / or one end of the sliding groove is gradually widened in the width direction of the guide rail.

[0052] In other words, the outer end 111 of the guide rail can be designed to be narrowed, forming guiding inclined surfaces on both sides. One end of the sliding groove close to the outer end 111 of the guide rail in the pulled-out state can be designed to be gradually widened, and the two side groove walls form guiding inclined openings.

[0053] In this way, under the cooperation and guidance of the guiding inclined surface and the guiding inclined opening, the guide rail can be more conveniently inserted into the sliding groove.

[0054] In some embodiments, the base assembly 10 includes a fixing member 13 and a guide rail as a sliding guiding structure 11, and the guide rail is arranged on the fixing member 13. The fixing member 13 has a positioning structure 131, and the guide rail has a positioning and mating structure 115 that mates with the positioning structure 131.

[0055] The fixing member 13 can be plate-shaped, the positioning structure 131 can be a positioning post, and the positioning and matching structure 115 can be a positioning hole. The guide rail is positioned and matched with the fixing member 13 through the positioning structure 131 and the positioning and matching structure 115, and can be mounted on the fixing plate via fixing parts 116. The fixing parts 116 can be, but are not limited to, screws, bolts, rivets, etc., and the guide rail is provided with corresponding mounting holes 117.

[0056] The guide rail can be made of stainless steel, which has excellent rust and energy resistance, and the tray body 30 can be made of polypropylene (PP) material, which has excellent acid and alkali resistance. The surfaces of the two materials are in contact with each other when pushed and pulled.

[0057] In this way, the guide rail is positioned and mounted on the mounting plate through the positioning structure 131 and the positioning matching structure 115 , the fixing member 13 is placed or fixed on the table of the detection equipment, and the tray body 30 can slide relative to the table of the detection equipment.

[0058] In some embodiments, the base assembly 10 has a limiting structure, which is configured to generate resistance to the sliding of the tray body 30 when the tray body 30 is in a pushed-in state and / or the tray body 30 is in a pulled-out state, at least so that when it is in the pushed-in state, pushing in encounters resistance, and when it is in the pulled-out state, pulling out encounters resistance.

[0059] In some embodiments, the retaining structure includes a first retaining structure 15 and a second retaining structure 17, and the tray body 30 has a first abutting portion 35 and a second abutting portion 37. When the tray body 30 is in the pushed-in state, the first abutting portion 35 abuts against the first retaining structure 15 to retain the tray body 30 in the direction from the outer end 111 toward the inner end 113. When the tray body 30 is in the pulled-out state, the second abutting portion 37 abuts against the second retaining structure 17 to retain the tray body 30 in the direction from the inner end 113 toward the outer end 111.

[0060] It can be understood that the abutment between the first abutting portion 35 and the first limiting structure 15 and the abutment between the second abutting portion 37 and the second limiting structure 17 can be direct abutment or indirect abutment.

[0061] Thus, when the tray body 30 is pushed into the pushed-in position, the first abutting portion 35 is blocked by the first limiting structure 15, preventing the tray body 30 from being pushed further inward. When the tray body 30 is pulled out to the pulled-out position, the second abutting portion 37 is blocked by the second limiting structure 17, preventing the tray body 30 from being pulled outward. During normal use, the tray body 30 remains in the maximum position, avoiding the risk of the tray body 30 falling and improving the safety of the reagent tray 100.

[0062] Specifically, the first limiting structure 15 is formed at the outer end 111 of the guide rail, and the first abutting portion 35 is formed at one end of the sliding groove in the extending direction. The second limiting structure 17 is a limiting post provided on the top surface of the guide rail. The groove wall of the sliding groove corresponding to the top surface of the guide rail has a sliding groove 38. The sliding groove 38 is consistent with the extending direction of the sliding groove. One end of the limiting post away from the top surface of the guide rail is located in the sliding groove 38 and can slide in the sliding groove 38 when the tray body 30 slides. The second abutting portion 37 is formed at one end of the sliding groove 38 in the extending direction.

[0063] In some embodiments, the reagent tray 100 further includes a buffer member 50. At least one of the surface of the first limiting structure 15 facing the first abutting portion 35, the surface of the first abutting portion 35 facing the first limiting structure 15, the surface of the first limiting structure 15 facing the first abutting portion 35, and the surface of the first abutting portion 35 facing the first limiting structure 15 is provided with the buffer member 50.

[0064] In other words, when the first abutting portion 35 abuts against the first limiting structure 15, the buffer member 50 is provided between the abutting surfaces of the two; and / or when the second abutting portion 37 abuts against the second limiting structure 17, the buffer member 50 is provided between the abutting surfaces of the two. The buffer member 50 can be made of an elastic material. The elastic material includes but is not limited to materials that can undergo elastic deformation such as rubber, springs, and sponges, and is not specifically limited herein.

[0065] Specifically, the surface of the first limiting structure 15 facing the first abutting portion 35 is provided with the buffer member 50, and the buffer member 50 plays a buffering role between the abutting surfaces of the first abutting portion 35 and the first limiting structure 15. The surface of the second abutting portion 37 facing the first limiting structure 15 is provided with the buffer member 50, and the buffer member 50 plays a buffering role between the abutting surfaces of the second abutting portion 37 and the second limiting structure 17.

[0066] In this way, the buffer member 50 has a buffering effect. When the tray body 30 is pushed into the pushed state and pulled out to the pulled state, the buffer member 50 buffers in both cases. The impact between the first abutting portion 35 and the first limiting structure 15 and the impact between the second abutting portion 37 and the second limiting structure 17 are both buffered by the buffer member 50, realizing buffer cooperation and reducing the risk of solution splashing after impact.

[0067] In some embodiments, the tray body 30 further has a push-pull handle 33. Specifically, the push-pull handle 33 is located at one end of the tray body 30 in the sliding direction, facilitating manual pushing and pulling of the tray body 30.

[0068] In some embodiments, the reagent tray 100 further includes a positioning member 70. The positioning member 70 is provided on the guide rail, and the groove wall of the sliding groove has a positioning groove 119 that cooperates with the positioning member 70; and / or the positioning member 70 is provided on the groove wall of the sliding groove, and the guide rail has a positioning groove 119 that cooperates with the positioning member 70.

[0069] Understandably, when the tray body 30 is in the pushed-in state, the positioning member 70 can be snapped into the corresponding positioning groove 119; and / or, when the tray body 30 is in the pulled-out state, the positioning member 70 can be snapped into the corresponding positioning groove 119 to achieve the positioning cooperation between the tray body 30 and the base assembly 10.

[0070] In this way, the positioning member 70 cooperates with the positioning groove 119 to help the tray body 30 and the base assembly 10 achieve positioning, ensuring the consistency of the position of the tray body 30 relative to the base assembly 10 in the length direction of the guide rail when the tray body 30 is in the pushed-in state and / or the pulled-out state, so that the tray body 30 can be at the same position every time it is pushed or pulled, ensuring the consistency of each experiment.

[0071] In some embodiments, the positioning member 70 is located on one side of the guide rail in the width direction, and at least part of the positioning member 70 is elastic. The positioning member 70 is provided on the guide rail and abuts against the wall of the sliding groove; and / or, the positioning member 70 is provided on the wall of the sliding groove and abuts against the guide rail.

[0072] Understandably, when the number of the positioning members 70 is one, it is provided on the wall of the guide rail or the sliding groove. When the number of the positioning members 70 is multiple, they can be provided on the wall of the guide rail or the sliding groove, or part of them can be provided on the guide rail and part of them can be provided on the wall of the sliding groove.

[0073] At least part of the positioning member 70 is elastic and can undergo elastic deformation to generate an elastic force. The positioning member 70 can be an elastic member as a whole, such as a spring, a rubber member, etc., or can be a combined member including a spring, a rubber member and a top bead, etc., as long as it can generate a thrust by abutting against the wall of the guide rail and / or the sliding groove, and no specific limitation is made here.

[0074] In this way, during the pushing and pulling process of the tray body 30 sliding relative to the base assembly 10, the positioning member 70 will abut against the wall of the guide rail or the sliding groove on one side, so that the other side of the guide rail is in close contact with the wall of the sliding groove, improving the position consistency of the tray body 30 in the width direction of the guide rail during the pushing and pulling process.

[0075] In some embodiments, the reagent tray 100 includes at least two positioning members 70, and all the positioning members 70 are arranged at intervals along the sliding direction.

[0076] Understandably, the positioning grooves 119 are correspondingly arranged at intervals along the sliding direction. Each positioning member 70 can be snapped into the positioning groove 119 located on its path by sliding, and each time it is snapped into a different positioning groove 119, the tray body 30 corresponds to a different position.

[0077] Specifically, among all the positioning members 70, there are two positioning members 70. When the tray body 30 is in the pushed-in state, one of them is snapped into the corresponding positioning groove 119, and when the tray body 30 is in the pulled-out state, the other one is snapped into the corresponding positioning groove 119.

[0078] In this way, on the one hand, all the positioning members 70 can meet the positioning requirements of different positions of the tray body 30, and can also better improve the position consistency of the tray body 30 in the width direction of the guide rail.

[0079] In some embodiments, the reagent tray 100 further includes a position-in-place detection member 90. The position-in-place detection member 90 is provided on the base assembly 10 and is used to detect whether the tray body 30 is in the designed position.

[0080] The position-in-place detection member 90 can be installed at the installation position on the fixing member 13 by screws. After the tray body 30 reaches the designed position, the position-in-place detection member 90 obtains the position information. In other words, the position-in-place detection member 90 obtaining the position information indicates that the tray body 30 is in the designed position. Among them, the designed position can be the position where the tray body 30 is in the pushed-in state and / or the position where the tray body 30 is in the pulled-out state.

[0081] The position-in-place detection member 90 can be, but is not limited to, an optocoupler detection member, a touch switch, etc., as long as the tray body 30 reaching the designed position can trigger the position-in-place detection member 90 to generate a signal, and no specific limitation is made here.

[0082] In this way, after the position-in-place detection member 90 obtains the corresponding position information, the detection device can perform the corresponding work.

[0083] Specifically, the tray body 30 has a detection portion 39, and the position-in-place detection member 90 is used to detect whether the detection portion 39 reaches the set position.

[0084] Among them, the position-in-place detection member 90 is an optocoupler detection member. As the tray body 30 slides, when the detection portion 39 reaches the set position, it will block the detection area of the optocoupler detection member, and then generate a detection signal, indicating that the detection portion 39 reaches the set position, that is, indicating that the tray body 30 is in the designed position.

[0085] In some embodiments, the tray body 30 is detachably installed on the base assembly 10.

[0086] In this way, when there is reagent or dirt on the guide rail, the tray body 30 can be removed, and then the guide rail can be wiped and cleaned.

[0087] When the above reagent tray 100 is in use, the tray body 30 can be pushed and pulled to slide along the guide rail on the fixing member 13. When pulled out to the maximum position, the tray body 30 is in the pulled-out state, and the positioning member 70 can cooperate with the positioning groove 119 to help the tray body 30 and the base assembly 10 achieve positioning. The buffer member 50 buffers the impact between the second abutting portion 37 and the second limiting structure 17, realizing the position function of the pulled-out positioning design of the tray body 30 and reducing the negative impact caused by the collision during pulling out. When pushed in to the maximum position, the tray body 30 is in the pushed-in state, and the positioning member 70 can cooperate with the positioning groove 119 to help the tray body 30 and the base assembly 10 achieve positioning. The buffer member 50 buffers the impact between the first abutting portion 35 and the first limiting structure 15, realizing the position function of the pushed-in positioning design of the tray body 30 and reducing the negative impact caused by the collision during pulling out. In addition, the in-place detection member 90 can accurately reflect whether the tray body 30 reaches the designed position, so as to determine whether the detection device starts to work.

[0088] In this way, the cooperation mode of the guide rail and the sliding groove improves the smoothness and directionality of the sliding of the tray body 30. The positioning member 70 improves the accuracy of the sliding positioning of the tray body 30. The buffer member 50 reduces the risk of solution splashing, increases the comfort of manual use, and the in-place detection member 90 can help the user accurately judge whether the tray body 30 is pushed in to the designed position.
