[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0032] The first aspect of the present invention provides a sample rack 50, such as Figure 1-Figure 2As shown, it includes: a sample rack body 51, on which a plurality of placement holes 52 are arranged at intervals along a first direction, and the placement holes 52 are used to install sample tubes 53; first guide grooves 54 and recessed portions 55 are respectively provided on both sides of the sample rack body 51, and the first guide grooves 54 extend toward the inside of the sample rack body 51 along the first direction, and the first guide grooves 54 penetrate the sample rack body 51 along the second direction; the recessed portion 55 extends downward to the bottom of the sample rack body 51; wherein the first guide grooves 54 are used to adapt to the first slide rails 62 on the lifting basket 60, so that the sample rack body 51 can be loaded in the lifting basket 60, and the sample rack body 51 can move along the first slide rails 62; the first direction is perpendicular to the second direction.

[0033] In the embodiment of the utility model, the first direction is, for example, the X direction in the coordinate system, the second direction is, for example, the Y direction, and the third direction is, for example, the Z direction. In order to facilitate the operation of the host 100 by the staff, when the staff stands on one side of the host 100 to operate, the side can be defined as the front side; the track conveying mechanism 400 can be set to be located at the rear side of the host 100, the sample library 300 is set on the left or right side of the host 100, and the loading area and the recycling area can be set to be front and back.

[0034] The sample rack body 51 is, for example, provided with a plurality of placement holes 52 spaced apart in the left-right direction, into which the sample tube 53 is inserted and fixed; the sample rack body 51 can be provided in an approximately rectangular parallelepiped shape, and one side of the sample tube 53 can be provided with an identification code to facilitate detection by a barcode scanner and / or a photoelectric sensor. For example, when the identification codes of the sample tubes 53 on the sample rack are all facing the front side, the barcode can be scanned and the sample information can be identified. If the sample rack is loaded upside down, the instrument will not be able to detect the sample or will generate erroneous information. In view of this, for example, a first guide groove 54 is provided on the left side of the sample rack body 51. Since the first guide groove 54, for example, extends rightward into the sample rack body 51 and the first guide groove 54 is through-through, the first guide groove 54 is sleeved on the first slide rail 62 of the basket 60, and the sample rack can be correctly installed in the basket 60. At this time, the identification codes of the sample tubes 53 on the sample rack are all facing the front side, and the sample rack can be prevented from tipping over in the front-to-back direction after being installed in the basket 60. A recessed portion 55 is provided on the right side of the sample rack body 51. If the sample rack is placed upside down during installation, the sample rack on the sample rack will When the identification codes of the sample tubes 53 are all facing the rear side, the recessed portion 55 cannot be matched with the first slide rail 62 of the basket 60, and the right side of the sample rack body 51 rests on the first slide rail 62. The sample rack body 51 is tilted, which indicates that the sample rack is not installed correctly. Therefore, the first guide groove 54 and the recessed portion 55 can be used together to prevent the sample rack from being loaded into the basket 60. When the sample rack is manually placed into the basket 60, there is a relatively obvious distinction between the front and back. In this way, when the sample rack is pushed into the instrument, various interference problems can be avoided, thereby ensuring the accuracy of the instrument's detection of the sample. Once the sample rack is placed upside down, the sample rack is not placed in place, which can be observed intuitively and needs to be re-placed correctly, otherwise the sample rack cannot be pushed into the instrument.

[0035] In some embodiments, a second guide groove 56 is provided at the bottom of the sample rack body 51, and the second guide groove 56 extends toward the inside of the sample rack body 51 along the third direction, and the second guide groove 56 penetrates the sample rack body 51 along the second direction; wherein, the second guide groove 56 is used to match with the second slide rail 63 on the basket 60, so that the sample rack body 51 is loaded in the basket 60, and the sample rack body 51 can move along the first slide rail 62 and the second slide rail 63; the first direction is perpendicular to the third direction. Specifically, for example, the second guide groove 56 extends longitudinally upward from the bottom of the sample rack body 51 to the inside of the sample rack body 51, and the second guide groove 56 penetrates front and back, and the second guide groove 56 cooperates with the second slide rail 63 at the bottom of the basket 60, and plays a guiding role when the sample rack moves back and forth in the basket 60.

[0036] In an exemplary embodiment, the sample rack body 51 is provided with a longitudinal center line along the first direction, and the second guide groove 56 deviates from the longitudinal center line; and the first guide groove 54 and the second guide groove 56 are respectively provided on both sides of the longitudinal center line. Specifically, for example, if the first guide groove 54 is provided on the left side of the sample rack body 51, then the second guide groove 56 can be provided on the right side close to the sample rack body 51, so that the sample rack is more stable and reliable when moving forward and backward in the basket 60. Of course, the second guide groove 56 can be provided at any position of the bottom of the sample rack body 51 to achieve a guiding role when the sample rack moves forward and backward in the basket 60, but when the second guide groove 56 is provided to deviate from the longitudinal center line, the second guide groove 56 and the first guide groove 54 can also play a foolproof role in loading the sample rack into the basket 60, that is, when the sample rack is manually placed in the basket 60, there is a relatively obvious distinction between front and back placement; if the sample rack is placed upside down, the sample rack cannot be correctly placed in the basket 60.

[0037] In some embodiments, a plurality of notches are provided on the side wall of the sample rack body 51, each notch corresponds to each of the placement holes 52, and the notches extend downward from the top of the sample rack body 51; the identification code on the sample tube 53 faces the notch, so as not to block the barcode scanner and / or photoelectric sensor from detecting the identification code. Specifically, for example, the notch can be provided on the front side of the sample rack body 51, and when the sample tube 53 is inserted into the placement hole 52, the identification code on the sample tube 53 faces the notch, so as not to block the barcode scanner and / or photoelectric sensor from detecting the identification code. The width of the notch in the left and right directions can be set to be smaller than the diameter of the placement hole 52, so as to prevent the sample tube 53 from tipping forward.

[0038] In some embodiments, a recessed square hole 57 is provided on the side wall of the sample rack body 51, and the square hole 57 is located on the other side opposite to the first guide groove 54 and above the recessed portion 55. Specifically, for example, the recessed square hole 57 is provided on the right side wall of the sample rack body 51; when the sample rack is installed in the basket 60, especially when the basket 60 is fully loaded, the operator inserts a finger into the recessed square hole 57, and can hold up the sample rack with one finger, so that it is easy to take out; that is, the operator lifts up from the square hole 57 on the right side of one of the sample racks, and the sample rack body 51 first disengages from the second slide rail 63, and then continues to lift the sample rack to the right, and the sample rack body 51 disengages from the first slide rail 62. Since the recessed portion 55 is provided on the right side of the sample rack body 51 and is located at the bottom, the interference between the sample rack body 51 and the side wall of the basket 60 can be avoided, which shows the ingenuity of the structural design of the sample rack body 51.

[0039] The second aspect of the present invention provides a basket 60, such as Figure 3-Figure 7As shown, it includes: a frame body 61, which includes: a bottom plate 611, and a first side wall 612 and a second side wall 613 connected to the bottom plate 611; the first side wall 612 and the second side wall 613 are relatively parallel and spaced apart; a storage space is formed between the first side wall 612 and the second side wall 613, and the storage space is used to load the sample rack; a plurality of sample racks are arranged side by side in the storage space along the second direction; wherein a first slide rail 62 is provided on the first side wall 612, and the first slide rail 62 is arranged to extend along the second direction; the first slide rail 62 is used to adapt to the first guide groove 54 on the sample rack body 51, so that the sample rack body 51 can be loaded in the basket 60, and the sample rack body 51 can move along the first slide rail 62. Specifically, for example, the rear side of the frame body 61 is set as an opening, which is convenient for the sample rack to move out of the basket 60 horizontally from front to back. The front side opposite to the opening can be provided with a third side wall 614, and one end of the first side wall 612 and the second side wall 613 are respectively connected to the third side wall 614, and the bottom of the third side wall is connected to the bottom plate 611; the setting of the third side wall 614 can prevent the sample rack loaded in the basket 60 from sliding out from the front side. The first side wall 612 is located on the left side, and the first side wall 612 is provided with a first slide rail 62, and the first slide rail 62 protrudes from the first side wall 612 to the right. For example, when the identification codes of the sample tubes 53 on the sample rack are all facing the front side, the code scanning and sample information identification can be realized. If the sample rack is placed upside down when loading, it will cause the instrument to fail to detect the sample or generate erroneous information. Once the sample rack is placed upside down, the sample rack is not placed in place, which can be observed intuitively, and it needs to be placed correctly again, otherwise the sample rack cannot be pushed into the instrument. In view of this, for example, a first guide groove 54 is provided on the left side of the sample rack body 51. Since the first guide groove 54, for example, extends rightward into the sample rack body 51 and the first guide groove 54 is through-through, the first guide groove 54 is sleeved on the first slide rail 62 on the left side wall of the basket 60, and the sample rack can be correctly installed in the basket 60. At this time, the identification codes of the sample tubes 53 on the sample rack are all facing the front side, and the sample rack can be prevented from tipping over in the front-to-back direction after being installed in the basket 60. A recessed portion 55 is provided on the right side of the sample rack body 51. If the sample rack is placed upside down during installation, the sample rack When the identification codes of the sample tubes 53 on the rack are all facing the rear side, the recessed portion 55 cannot be matched with the first slide rail 62 of the basket 60, and the right side of the sample rack body 51 is placed on the first slide rail 62. The sample rack body 51 is tilted, which indicates that the sample rack is not installed correctly. Therefore, the first guide groove 54 and the recessed portion 55 are used together to prevent the sample rack from being loaded into the basket 60. When the sample rack is manually placed into the basket 60, there is a relatively obvious distinction between the front and back. In this way, when the sample rack is pushed into the interior of the instrument, various interference problems can be avoided, thereby ensuring the accuracy of the instrument's detection of the sample.

[0040] In some embodiments, a second slide rail 63 is provided on the bottom plate 611, the second slide rail 63 is configured to extend along the second direction, and the second slide rail 63 is located near the second side wall 613; the second slide rail 63 is used to match the second guide groove 56 on the sample rack body 51, so that the sample rack body 51 is loaded in the basket 60, and the sample rack body 51 can move along the first slide rail 62 and the second slide rail 63. Specifically, for example, the second slide rail 63 is provided on the right side close to the bottom plate 611, the second slide rail 63 protrudes upward from the bottom plate 611, and the second guide groove 56 matches the second slide rail 63, and plays a guiding role when the sample rack moves back and forth in the basket 60. In addition, the first guide groove 54 is compatible with the first slide rail 62. For example, if the first guide groove 54 is arranged on the left side of the sample rack body 51, then the second guide groove 56 can be arranged on the right side close to the sample rack body 51, so that the sample rack is more stable and reliable when moving back and forth in the basket 60; moreover, the second guide groove 56 and the first guide groove 54 are used in conjunction to prevent the sample rack from being mistakenly loaded into the basket 60, that is, when the sample rack is manually placed in the basket 60, there is a relatively obvious distinction between the front and back; if the sample rack is placed upside down, the sample rack cannot be correctly placed in the basket 60.

[0041] In some embodiments, the basket 60 further includes: a handle 64, which is set as a U-shaped structure; the outer surfaces of the first side wall 612 and the second side wall 613 are both provided with grooves that penetrate along the third direction, and the two ends of the handle 64 are inserted into the grooves, and the handle 64 is connected and fixed to the first side wall 612 and the second side wall 613 by threaded fasteners. The arrangement of the handle 64 facilitates the transportation of the basket 60; for example, two handles 64 can be arranged at intervals in front and behind, which is more conducive to the stability of the basket 60 during transportation.

[0042] In some embodiments, the basket further includes: a blocking mechanism, which is arranged at the opening, and the blocking mechanism includes: a blocking member 65, which is rotatably mounted on the end of the bottom plate; an elastic member, which acts on the action end of the blocking member 65, so that the free end of the blocking member swings upward and is higher than the bottom plate 611, so as to prevent the sample rack 50 loaded in the basket from sliding out. Specifically, when the elastic member applies a force to one end of the blocking member 65, the other end of the blocking member can swing upward, and when it is higher than the top surface of the bottom plate 611, it can prevent the sample rack 50 loaded in the basket from sliding out; this is conducive to and convenient for carrying the basket.

[0043] In some embodiments, an inwardly recessed accommodation area is provided at the end of the bottom plate 611; the blocking mechanism also includes: a fixed shaft 66 and a fixed plate 67, the fixed shaft 66 is located in the recessed accommodation area, and one end of the fixed shaft 66 is connected and fixed to the bottom plate, the other end of the fixed shaft 66 extends horizontally toward the opening, the elastic member is configured as a torsion spring 68, the fixed shaft 66 is sequentially sleeved with the torsion spring 68, the blocking member and the fixed plate 67, the fixed plate 67 is connected and fixed to the end of the bottom plate, so that the fixed plate 67 axially presses the torsion spring 68 and the blocking member; wherein, one end of the torsion spring 68 is connected and fixed to the bottom plate, the other end of the torsion spring 68 presses downwardly against the active end of the blocking member, so that the free end of the blocking member swings upward and is higher than the bottom plate; when the active end of the blocking member is pushed upward, the free end of the blocking member swings downward and is lower than the bottom plate. Specifically, the end of the bottom plate 611 is provided with an inwardly recessed groove to form a accommodating area; the fixed plate 67 and the end of the bottom plate 611 can be connected and fixed by a screw, and the two ends of the fixed shaft 66 are respectively inserted into the bottom plate 611 and the fixed plate 67, the torsion spring 68 and the blocking member 65 are sleeved on the fixed shaft 66 and are located in the accommodating area, the blocking member 65 can rotate around the fixed shaft 66, and the fixed plate 67 axially positions the torsion spring 68 and the blocking member 65, and the free end and the active end of the blocking member are respectively located on the left and right sides of the fixed shaft 66, one end of the torsion spring 68 is connected and fixed to the bottom plate 611 to generate a pre-tightening force, so that the other end of the torsion spring 68 presses downward against the active end of the blocking member 65, and then the free end of the blocking member swings upward and is higher than the bottom plate 611. When the working end of the blocking member 65 is pushed upward, the pushing force overcomes the preload force of the torsion spring 68, and the blocking member 65 rotates clockwise, causing the free end of the blocking member to swing downward and be lower than the bottom plate. At the same time, the top surface of the working end of the blocking member 65 is lower than the top surface of the bottom plate 611. At this time, the sample rack 50 can slide out of the opening smoothly.

[0044] In some embodiments, the blocking mechanism also includes: a limit block 69, which is arranged in the recessed accommodating area, and the limit block 69 is connected and fixed to the bottom plate; the blocking member includes a rotating arm and a horizontal plate connected to one side of the rotating arm, and the rotating arm is provided with a mounting hole, and the mounting hole is adapted to the fixed shaft 66; the horizontal plate constitutes the active end of the blocking member, and the active end and the free end of the blocking member are respectively located on both sides of the mounting hole along the first direction; when the other end of the torsion spring 68 presses downward against the active end of the blocking member, the other end of the torsion spring 68 contacts the top surface of the horizontal plate, and the bottom surface of the horizontal plate contacts the limit block 69; in the recessed accommodating area, a plurality of adjustment holes 70 are provided on the bottom plate, one end of the torsion spring 68 is fixed in the adjustment hole 70, and the adjustment hole 70 is used to adjust the preload force of the torsion spring 68. Specifically, the cross plate is connected to one side of the rotating arm approximately vertically, and the cross plate is arranged to extend backward. The arrangement of the cross plate increases the contact area of ​​the force, which is beneficial to the stability of the structure when the blocking member 65 rotates; the distance between the center of the mounting hole on the rotating arm and the end of the free end is set to be greater than the distance between the center of the mounting hole and the end of the action end; when the other end of the torsion spring 68 presses downward against the cross plate, the bottom surface of the cross plate contacts the limit block 69, which can make the blocking member 65 rotate counterclockwise by a certain angle, and the free end of the blocking member 65 can be higher than the top surface of the bottom plate 611 by a certain height, so as to prevent the blocking member 65 from rotating too much. The large angle makes the horizontal plate extend beyond the bottom surface of the bottom plate 611. When the horizontal plate is higher than the bottom surface of the bottom plate 611, it is convenient for the basket to be placed on any table. When the basket is placed in the loading area, for example, a matching upwardly protruding push rod is provided at the corresponding position of the shelf. The push rod pushes the horizontal plate upward. The lifting force overcomes the preload force of the torsion spring 68. The blocking member 65 rotates clockwise, causing the free end of the blocking member to swing downward and be lower than the bottom plate. At the same time, the top surface of the action end of the blocking member 65 is lower than the top surface of the bottom plate 611. At this time, the sample rack 50 can smoothly slide out of or enter the basket from the opening. The setting of the adjustment hole 70 is convenient for flexibly adjusting the preload force of the torsion spring 68. When the basket is moved away from the shelf, the free end of the blocking member 65 can be controlled to pop out and be higher than the top surface of the bottom plate 611, thereby preventing the sample rack 50 from sliding out of the basket when the basket is transported.
