Referring to fig. 11, the present embodiment provides a sample storage device 1, which includes a sample box 10, a sample rack 200, a power mechanism 400, and a rack 500. The sample storage device can be used for storing samples by the detection equipment. The sample cartridge 10 includes a cartridge body 100 and a stopper mechanism 300.

Further, referring to fig. 1 and 2, the cartridge body 100 includes a cartridge body 110 and a bottom cover 120, and the cartridge body 110 is provided with a plurality of sample channels 111 arranged at intervals to accommodate the sample racks 200.

It is understood that the sample channels 111 may be a plurality of sample racks arranged in parallel on the box body 110, so that a plurality of sample racks can be simultaneously disposed in the box body 110. In addition, in other embodiments, the number of the sample channels 111 may be one.

Alternatively, the bottom cover 120 and the case 110 may be mounted by, but not limited to, bolting, clamping, riveting, welding, bonding, pinning, etc. Of course, the molding can be integrated. Wherein the integral molding mode can be injection molding, casting and the like.

Specifically, the bottom cover 120 is bolted to the case 110.

In one embodiment, referring to fig. 3, the box body 110 is provided with a groove 112. The groove 112 is located on the side of the cartridge body 110 remote from the sample channel 111. The bottom cover 120 is seated on the groove 112. The bottom wall 114 of the sample channel 111 is opened with a through hole 113. The through hole 113 is provided at the opening 1111 remote from the sample channel 111, and the through hole 113 communicates with the groove 112.

Further, the bottom cover 120 is provided with a notch 121. The notch 121 is extended from the bottom cover 120, and is used for extending the output end of the power mechanism 400 into the bottom cover 120 to drive the limiting mechanism 300.

Furthermore, a through-type boss 122 is disposed on a side of the bottom cover 120 away from the notch 121. The boss 122 can be inserted into the groove 112 and fixedly connected with the box body 110. The through space of the boss 122 is used for fingers of an operator to extend into, so that the sample box 10 can be conveniently held by hands.

In one embodiment, referring to fig. 1 and 2, cassette body 110 has a bottom wall 114, an end wall 150, and two spaced apart side portions 140. An end wall 150 and two side walls 140 are provided on the bottom wall 114. One end of each of the two side walls 140 is connected to an end wall 150. A plurality of partitions 130 are disposed in the box body 110 in parallel at intervals. Each of the partitions 130 extends in the direction of the end wall 150 such that the cartridge body 110 cooperates with the plurality of partitions 130 to form the plurality of sample channels 111.

In one embodiment, referring to fig. 3, 5 and 7, the limiting mechanism 300 includes a limiting member 310. At least a part of the limiting member 310 is movably inserted into the through hole 113 and is used for driving and matching with the power mechanism 400. The limiting member 310 is provided with a first buckling position 311, and the sample holder 200 is provided with a second buckling position 210. The limiting member 310 can drive the first buckling position 311 to move along the first direction under the driving of the power mechanism 400, so as to be coupled with the second buckling position 210 of the sample rack 200; the limiting member 310 can drive the first snap-fit portion 311 to disengage from the second snap-fit portion 210 of the sample holder 200 along a second direction under the driving of the power mechanism 400, wherein the first direction is opposite to the second direction. The first direction is a direction away from the bottom cover 120 along the through hole 113, and the second direction is a direction approaching to the bottom cover 120 along the through hole 113. Therefore, when the sample rack 200 is accommodated in the sample passage 111, the power mechanism 400 is activated to drive the limiting member 310 to move toward the first direction, so that the first latching portion 311 of the limiting member 310 is in the ejected state, and thus the second latching portion 210 of the sample rack 200 in the sample passage 111 can be coupled with the ejected first latching portion 311, so that the sample rack 200 is stably and reliably limited in the sample passage 111. In addition, when the sample rack 200 needs to be taken out, the limiting member 310 can be driven to move towards the second direction again by the power mechanism 400, and the first buckling position 311 is retracted, so as to release the connection between the first buckling position 311 and the second buckling position 210, thereby ensuring that the sample rack 200 can be easily taken out from the box body 100 when necessary.

Optionally, the first fastening portion 311 is a convex structure, and the second fastening portion 210 is a groove or hole structure; or the first buckling position 311 is a groove or hole structure, and the second buckling position is a convex structure.

Specifically, the first fastening portion 311 is a convex-structured limiting tooth, and the second fastening portion 210 is a groove-structured limiting groove.

Referring to fig. 5, it should be noted that the driving cooperation manner of the limiting member 310 and the power mechanism 400 may be a direct driving manner or an indirect driving manner. When the driving engagement manner of the limiting member 310 and the power mechanism 400 is an indirect driving manner, an intermediate structure is connected between the limiting member 310 and the power mechanism 400, for example: a connector 320, etc.

Referring to fig. 6, further, the limiting mechanism 300 further includes a connecting member 320. The connecting member 320 is located on a side of the cartridge body 110 opposite to the sample channel 111, and is connected to the limiting member 310 below the through hole 113, and the connecting member 320 is used for driving and matching with the power mechanism 400. As can be seen, the driving engagement between the limiting member 310 and the power mechanism 400 is indirect driving. That is, the power mechanism 400 is started, and the connecting member 320 is driven to drive the limiting member 310 to move toward the first direction, so that the first buckling position 311 on the limiting member 310 is in the ejected state, and thus the second buckling position 210 of the sample rack 200 located in the sample channel 111 can be coupled with the ejected first buckling position 311, so that the sample rack 200 is stably and reliably limited. When the sample rack 200 needs to be taken out, the connecting member 320 can be driven by the power mechanism 400 again to drive the limiting member 310 to move toward the second direction, and the limiting member 310 and the first fastening position 311 are retracted to release the connection between the first fastening position 311 and the second fastening position 210. Meanwhile, when the connecting member 320 and the limiting member 310 are divided into two parts, the difficulty of machining and casting a single part is reduced, the production cost is reduced, and the production and installation of the limiting mechanism 300 are more flexible.

Furthermore, one side of the connecting member 320 is fixedly connected to one side of the limiting member 310 away from the first fastening portion 311. The connection mode shown in the figures is a screw connection mode, that is, the connection portion of the position limiting member 310 and the connection member 320 is provided with screw holes, and the position limiting member 310 and the connection member 320 can be screwed by screws. It is understood that the connection mode is not only screw connection, but also welding, gluing and the like can be used.

In one embodiment, referring to fig. 1 and 4, when the sample holder 200 is received in the sample channel 111, the first fastening portion 311 of the limiting member 310 is coupled to the second fastening portion 210 of the sample holder 200 to prevent the sample holder 200 from coming out of the sample channel 111 from the opening 1111; when the sample rack 200 needs to be removed from the sample passage 111, the power mechanism 400 may be operated to disengage the second latch 210 of the sample rack 200 from the first latch 311 of the limiting member 310.

It is understood that the number of the first fastening portions 311 on the limiting member 310 may be one or more. When the number of the first fastening locations 311 is plural, one limiting member 310 can be used to simultaneously connect to a plurality of sample racks 200. In addition, when the sample rack 200 is connected, the distance between two adjacent first fastening positions 311 may be opposite to one second fastening position 210, so that two adjacent first fastening positions 311 can be inserted into one second fastening position 210, thereby increasing the stability of the installation of the sample rack 200.

It should be noted that the number of the first fastening positions 311 is not limited to a plurality, and may be one. When there is one first catch 311, one first catch 311 mates with the second catch 210 of each sample rack 200.

Further, referring to fig. 2, each partition 130 has a gap with the end wall 150. The first buckle 311 can move in the gap under the driving of the limiting member 310. Specifically, the box body 110 is provided with a containing groove 180, and the containing groove 180 is located on the end wall 150 of the box body 110 and is communicated with the through hole 113. A notch of the receiving groove 180 faces each of the partitions 130 such that each of the partitions 130 forms a gap with the end wall 150. The receiving groove 180 can receive at least a portion of the limiting member 310. The accommodating groove 180 allows the first buckle 311 to move in the space of the box body 100 under the driving of the power mechanism 400. It should be noted that the accommodating groove 180 may be omitted. When the receiving groove 180 is omitted, a notch may be formed on a side of each partition 130 close to the end wall 150, so that a gap is formed between each partition 130 and the end wall 150, so that the first locking portion 311 can move.

In one embodiment, referring to fig. 6, the connecting member 320 includes a connecting body 325, a first bending portion 322, and a second bending portion 321. The connection body 325 is connected to the stopper 310. The first and second bent portions 322 and 321 are connected to the connection body 325. The second bending portion 321 is used for driving and matching with the power mechanism 400. Further, the first bending portion 322 is disposed closer to the limiting member 310 than the second bending portion 321. One side of the first bending portion 322 facing away from the second bending portion 321 can be in limit fit with one side of the box body 100 (for example, one side of the box body 110 facing the bottom cover 120) to limit the driving stroke of the power mechanism 400 on the limiting member 310, so as to ensure that the limiting mechanism 300 is stably and reliably coupled with the box body 100. A connection hole 323 is further formed at a position where the connection body 325 of the connection member 320 is connected to the second bending portion 321. The limiting mechanism 400 can be inserted into the connecting hole 323 to be connected to the connecting member 320, so as to drive the connecting member 320.

It should be noted that there are various molding manners for connecting the first bending portion 322 and the second bending portion 321 to the connecting body 325, and this embodiment is not particularly limited, for example: the first bending portion 322 and the second bending portion 321 may be formed on the connecting body 325 in the following manner: bolt connection, clamping connection, riveting connection, welding connection, bonding connection, pin connection and the like; of course, the method can also be integrated, such as: opposite ends of the connection body 325 are bent in an arbitrary direction to form a first bent portion 322 and a second bent portion 321, respectively.

Specifically, opposite ends of the connection body 325 are respectively bent toward the same side to form a first bent portion 322 and a second bent portion 321. The first bending portion 322 and the second bending portion 321 are bent toward the same side, so that the assembling space of the connecting member 320 can be better saved.

Further, one or more buffering pads 324 may be disposed on a side of the first bending portion 322 away from the second bending portion 321, and under the action of the elastic member 330, the buffering pads 324 are located between the first bending portion 322 and the case 110, so as to prevent the first bending portion 322 from directly contacting the case 110 when the connection member 320 moves toward the case 110, reduce adverse effects on the sample caused by vibration during the operation of the apparatus, and reduce wear between the first bending portion 322 and the case 110, so as to increase the service life of the apparatus. It is understood that the buffer pad 324 may also be fixed on the case 110, and may be a silicone pad, a rubber pad, a foam pad, or other elastic elements. Note that the cushion pad 324 may be omitted if the effect of the cushion is not considered.

In one embodiment, referring to fig. 5, the limiting mechanism 300 further includes an elastic member 330. The elastic member 330 is disposed between the connecting member 320 and the box body 100 to elastically connect the limiting member 310 and the box body 100. Thus, when the first fastening portion 311 is coupled to the second fastening portion 210, the elastic member 330 elastically supports the connecting member 320, so that the limiting member 310 has a certain elastic retaining force, thereby effectively preventing the limiting member 310 from sliding downward due to its own weight and causing the coupling to be loosened, and further enabling the limiting on the sample member 200 to be more stable and reliable.

Alternatively, the elastic member 330 may be a spring, elastic rubber, elastic metal sheet, or the like.

Specifically, the elastic member 330 is a spring.

Further, referring to fig. 3, 4 and 6, the bottom cover 120 is provided with a first connecting portion 1231, and the first bending portion 322 is provided with a second connecting portion 3221 at a position facing the second bending portion 321. The elastic element 330 is disposed between the connecting element 320 of the limiting mechanism 300 and the bottom cover 120, and opposite ends of the elastic element 330 are respectively connected to the first connecting portion 1231 and the second connecting portion 3221. The connection may be by abutment, adhesive or other fixed or movable connection. The elastic member 330 can provide a supporting force to the connecting member 320 so that the connecting member does not directly contact with the bottom cover 120 in an operating state, and when the sample holder 200 is coupled to the stopper 310, the connecting member 320 is supported to ensure that the stopper 310 is coupled to the sample holder 200.

It can be understood that the number of the first connecting portion 1231, the second connecting portion 3221 and the elastic member 330 is not limited to two, and may be one or more.

In one embodiment, referring to fig. 7, the sample holder 200 is provided with a second fastening portion 210, and the second fastening portion 210 can be coupled to the first fastening portion 311 of the limiting member 310 to limit the sample holder 200 by the limiting mechanism 300. When the second fastening portion 210 of the sample holder 200 is coupled to the first fastening portion 311 of the limiting member 310, the sample holder 200 is received in the sample passage 111.

It is understood that the size of the sample rack 200 can be adjusted according to the size of the sample channel 111, and the size of the second catching position 210 can also be adjusted according to the size of the first catching position 311. In addition, the first fastening portion 311 and the second fastening portion 210 can be both of a tooth structure or a fastening structure.

Further, the friction between the first fastening portion 311 and the second fastening portion 210 can be increased to increase the stability of the first fastening portion 311 and the second fastening portion 210.

Optionally, the mating surfaces of the first fastening portion 311 and the second fastening portion 210 form a friction surface; the surface of the first buckle position 311 or the second buckle position 210 is provided with a limiting protrusion (not shown), and the surface of the second buckle position 210 or the first buckle position 311 is provided with a groove (not shown) which is engaged with the limiting protrusion.

Specifically, in the present embodiment, the mating surfaces of the first fastening portion 311 and the second fastening portion 210 form friction surfaces with each other, so as to increase the stability of the mating of the first fastening portion 311 and the second fastening portion 210.

In one embodiment, referring to fig. 1 and 8, the power mechanism 400 includes a transmission structure 430, a fixing member 410, and a power source 420, wherein one end of the fixing member 410 is fixedly connected to the transmission structure 430, the other end of the fixing member is connectable to the connection hole 323 of the connection member 320, and an output end of the power source 420 is connected to the transmission structure 430 to control the movement of the fixing member 410. When the power mechanism 400 operates, the power source 420 outputs kinetic energy to drive the transmission structure 430 to move, and the transmission structure 430 drives the fixing element 410 fixed thereon to move. Since the fixing member 410 can extend into the bottom cover 120 through the notch 121 and is fastened to the connecting hole 323 of the connecting member 320, the power mechanism 400 can drive the whole limiting mechanism 300 to move, thereby realizing the limiting control of the sample rack 200.

Further, the power mechanism 400, the limiting mechanism 200 and the through hole 113 are all arranged on one side of the opening 1111 far away from the sample channel 111, so that the whole structure is more compact, and the installation space is saved.

Specifically, the transmission structure 430 includes a gear 431, a rack 432, and a rack guide 433. The output end of the power source 420 is connected with the axis of the gear 431, the gear 431 is meshed with the rack 432, one end of the rack 432 close to the fixing piece 410 is fixedly connected with the fixing piece 410, and the rack 431 is movably connected with the rack guide block 433. The power source 420 rotates the gear 431 around the axis of the gear 431, and the gear 431 is engaged with the rack 432 and moves the rack 432 to change the rotational movement into the linear movement. When the power source 420 outputs kinetic energy, the rack 432 moves along the direction defined by the rack guide 433, and drives the fixing member 410 to move.

It should be noted that the power source 420 may be a manual power mechanism or an automatic power mechanism, wherein the automatic power mechanism may be an element capable of outputting kinetic energy, such as a motor, an air cylinder, a hydraulic cylinder, an electric cylinder, and the like.

Specifically, power source 420 is an electric motor.

Further, a spring 440 may be further installed below the rack 432 to prevent the rack 432 from sliding down due to its own weight against the self-locking force of the power source 420 in a state where the power source 420 does not operate.

In one embodiment, referring to fig. 9 and 10, the rack 500 includes a bottom plate 510 and two or more side plates 520 spaced apart from the bottom plate 510, and a receiving space is formed between the bottom plate 510 and two adjacent side plates 520 to receive the sample box 10. The two ends of the accommodating space are respectively provided with an inlet (not shown) and an outlet (not shown), and the sample box 10 enters the accommodating space from the inlet; at the same time, the sample rack 200 on the sample cartridge 10 can be pulled out of the sample cartridge 10 through the outlet.

In one embodiment, a blocking member (not shown) is disposed at an outlet of the rack 500, and the blocking member may be disposed on the bottom plate 510 or the side plate 520. When the sample cartridge 10 is located in the storage space, the stopper can abut against the sample cartridge 10 and does not block the opening 1111 of the sample passage 111. In this way, the sample cartridge 10 can be prevented from slipping out from the outlet of the storage space by providing the stopper, so that the mounting stability of the sample cartridge 10 can be increased, and the stability of storing the sample in the sample cartridge 10 can be improved.

In one embodiment, referring to fig. 1 and 9, two opposite sides of the two side plates 520 may be provided with opposite insertion slots 530, and correspondingly, two opposite sides of the sample box 10 may also be provided with insertion pieces 160. When the sample box 10 is accommodated in the accommodating space of the rack 500, the connectors 160 on both sides of the sample box 10 can be inserted into the insertion grooves 530 on the rack 500, so that the sample box 10 is fixed on the rack 500.

Specifically, the insertion slot 530 in this embodiment is a strip-shaped insertion slot, and the insertion member 160 is a strip-shaped insertion member.

It is understood that the shape of the insertion slot 530 and the insertion member 160 can be any shape that can achieve insertion fixation; the insertion grooves 530 may be provided on both sides of the sample container 10, and accordingly, the insertion pieces 160 may be provided on the side plates 520.

Specifically, in order to increase the mounting stability of the sample cartridge 10, the frictional force between the plug 160 and the groove wall of the insertion groove 530 may be increased. For example: using a material with a higher coefficient of friction or increasing the unevenness of the surfaces of the plug 160 and the socket 530, etc.

In one embodiment, referring to fig. 9 and 10, the rack 500 is provided with a first positioning portion 540, and the bottom cover 120 of the sample box 10 is provided with a second positioning portion 170 corresponding to the first positioning portion 540. The first aligning portion 540 is aligned with the second aligning portion 170 so that the sample box 10 is fixed on the rack 500. It is understood that the first alignment part 540 can be an alignment protrusion or an alignment groove, and correspondingly, the second alignment part 170 can be an alignment groove or an alignment protrusion.

Specifically, the alignment protrusion is a ball plunger commonly used in the mechanical field.
