In some embodiments, the number of the concave portions 21 is plural, and the plural concave portions 21 are provided at intervals in the left-right direction of the housing 14. Illustratively, the number of the recesses 21 is two, three or more, and each recess 21 is provided with one pin hole 2121. The plurality of concave portions 21 are provided along the left-right direction of the housing 14 such that the pin holes 2121 are provided at intervals along the left-right direction of the housing 14, so that the sample introduction device 20 can be adapted to analysis devices 10 of different sizes or layouts, and the applicability or reusability of the sample introduction device 20 is improved.

Illustratively, the left-right direction of the housing 14 is the X1 and X2 directions in the drawing.

Illustratively, the number of the concave portion 21 is one, and a plurality of pin holes 2121, i.e., two, three or more pin holes 2121, are provided on the concave portion 21, and the plurality of pin holes 2121 are spaced along the left-right direction of the housing 14, so that the sample injection device 20 can be adapted to analysis devices 10 with different sizes or layouts, and the applicability or reusability of the sample injection device 20 is improved.

Of course, in other embodiments, the number of the concave portions 21 is at least two, and the number of the pin holes 2121 provided in each concave portion 21 may be different, and is not limited herein.

Referring to fig. 23(a) and 23(b), a plurality of pin holes 2121 illustratively include pin holes a1 and pin holes a 2. The pin holes a1 and a pin hole a2 are provided at intervals in the X1 and X2 directions in the drawing. Referring to fig. 23(a), when the protrusion 132 of the analyzer B1 is inserted into the pin hole a1 of the sample injector 20, the sampling site on the sample injector 20 is aligned with the sampling needle 121 on the analyzer B1, and the pin hole a2 of the sample injector 20 does not interfere with the analyzer B1. When the protrusion 132 of the analyzer B2 is engaged with the pin hole a2 of the sample injector 20, the sampling site on the sample injector 20 is aligned with the sampling needle 121 on the analyzer B2, and the pin hole a1 of the sample injector 20 does not interfere with the analyzer B2.

Illustratively, the pin hole a1 is disposed adjacent to one end of the sample injection device 20. The pin hole a2 is located near the middle of the sample injection device 20. For example, the analyzer B1 and the analyzer B2 each have only one protrusion 132 to avoid interference of the extra protrusion 132 with the sample injector 20 or the analyzer 10.

Illustratively, the plurality of recesses 21 or the plurality of pin holes 2121 are provided at intervals in the directions X1 and X2 in the drawing.

In some embodiments, the second connecting portion 211 and the setting portion 212 are disposed at an angle. Of course, the included angle between the second connection portion 211 and the setting portion 212 may also be 0 degree, and both the pin hole 2121 and the second connection portion 211 are disposed on the side of the sample injection device 20 facing the analysis device 10.

In some embodiments, the first connection portion 131 is fixedly connected to the front plate 142 of the analysis device 10 by a snap connection, an adhesive connection, a screw connection, or the like, and the second connection portion 211 is fixedly connected to the sample injection device 20 by a snap connection, an adhesive connection, a screw connection, or the like. Thus, the analyzer 10 and the sample injection device 20 can be selectively manufactured by the same manufacturer and respectively installed with the protruding part 13 and the concave part 21; alternatively, the protrusion member 13 and the concave portion 21 may be mounted after being processed by different manufacturers, so that the sampling needle 121 and the sampling site are aligned and positioned. Therefore, a manufacturer of the sample analyzer 100 can be flexibly selected, and the practicability is high.

Due to machining errors, the actual position of the boss 132 (or the actual position of the pin hole 2121) may not be exactly the same as the design position of the boss 132 (or the design position of the pin hole 2121). Thus, the relative position of the projection member 13 and the front side plate 142 needs to be adjusted before shipment or at the time of assembly of the sample analyzer 100; and/or adjusting the relative position of the concave portion 21 and the sample injection device 20, so that the protruding portion 132 is matched with the pin hole 2121 of the concave portion 21, thereby realizing the alignment positioning of the sampling needle 121 and the sampling position. To this end, in some embodiments, the first connection portion 131 is detachably connected to the front side plate 142 of the analysis device 10; and/or the second connection part 211 is detachably connected with the sample introduction device 20. In this way, before the sample analyzer 100 is shipped or assembled, the relative positions of the protrusion 132 and the front plate 142 may be adjusted, so that the projection of the protrusion 132 and the sampling needle 121 on the horizontal plane is separated by the preset distance; and/or adjusting the relative position of the pin hole 2121 and the sampling device 20, so that the pin hole 2121 is spaced from the projection of the sampling site on the horizontal plane by the preset distance, so that the sampling needle 121 and the sampling site can be aligned and positioned.

Referring to fig. 9, 10 and 14, in some embodiments, the sample analyzer 100 further includes a second retaining member 40. The second connecting portion 211 is provided with a second through hole 2111, and the second locking member 40 is connected to the sample injection device 20 through the second through hole 2111.

Illustratively, the second locking member 40 is disposed through the second through hole 2111 and locked on the sample introduction device 20. The second locking member 40 can be a quick release connector such as a screw or bolt.

It can be understood that the number of the second through holes 2111 and the number of the second locking members 40 can be designed according to actual requirements, such as one, two, three or more, as long as the number of the second through holes 2111 and the number of the second locking members 40 are adapted. Exemplarily, the number of the second through holes 2111 and the second locking members 40 is multiple, i.e., two, three or more, and each second through hole 2111 corresponds to one second locking member 40, so as to improve the connection reliability of the recess 21 and the sample injection device 20.

Referring to fig. 13 and 14, in some embodiments, the sample injection device 20 includes a device bottom plate 23. It will be understood that when the sample introduction device 20 comprises a track, the track comprises a device floor 23. When the sample injection device 20 comprises a sample injector, the sample injector comprises a device base plate 23.

In some embodiments, the device floor 23 includes a bottom wall 231 and a bent wall 232. The bent wall 232 is bent upward from the end of the bottom wall 231 near the analysis device 10. The second locking member 40 is inserted into the second insertion hole 2111 and locked on the bottom wall 231, so as to lock and fix the second connecting portion 211 and the sample injection device 20.

Illustratively, the second connection portion 211 is parallel to the bottom wall 231. The bent wall 232 is parallel to the setting portion 212.

Illustratively, a bent wall 232 is provided between the setting portion 212 and the front side plate 142. The bending wall 232 is provided with an avoiding hole (not labeled), and the protrusion 132 can penetrate through the avoiding hole to match with the pin hole 2121 of the setting portion 212.

Referring to fig. 24, in some embodiments, the dimension of the protrusion 132 along the vertical direction of the housing 14 is smaller than the dimension of the pin hole 2121 along the vertical direction. Illustratively, the dimension of the protrusion 132 along the Z1 and Z2 directions is smaller than the length of the opening of the pin hole 2121 along the Z1 and Z2 directions to accommodate the position offset of the protrusion 132 and the pin hole 2121 in the up-down direction (i.e., the Z1 and Z2 directions) and reduce the processing difficulty or the assembly difficulty of the sample analyzer 100.
