Example one

As shown in FIGS. 8, 10 and 12, the direction of the sample rack 201 moving from the inlet 141 of the sample channel 14 to the outlet 142 of the sample channel 14 is set to be a first direction, whereas the direction from the outlet 142 of the sample channel 14 to the inlet 141 of the sample channel 14 is set to be a second direction, i.e. the first direction is opposite to the second direction. It should be understood that the above setting is only for the convenience of describing the moving direction of the pushing assembly 20 for transporting the sample rack outwards when the sample introduction device 100 is in the working state, and should not be construed as limiting the present application.

As shown in fig. 1 to 4, embodiments of the present application provide a sample introduction device 100 that can be used in a transport apparatus and a sample analysis instrument for loading and transporting a sample rack tray 200. The sample introduction device 100 includes a loading seat 10, a pushing assembly 20, and a limiting plate 30.

The loading seat 10 is provided with a sample feeding channel 14, and a limiting plate 30 is arranged on the loading seat 10 at one end of the sample feeding channel 14. Optionally, at least one of the two sides of the sample introduction channel 14 is provided with a guide groove, and the guide groove is provided with a limiting plate 30. The stopper plate 30 may also be provided directly on the carriage 10 without a guide groove for abutting against the push assembly 20. Meanwhile, an inlet 141 is provided at one end of the sample introduction channel 14, an outlet 142 is provided at the other end, and an opening which is completely opened is opened at the top of the sample introduction channel 14. The sample rack tray 200 can be placed into the sample channel 14 from the inlet 141 of the sample channel 14.

The pushing assembly 20 comprises a support 21, a pushing member and an elastic member, and the pushing assembly 20 reciprocates along the direction of the sample feeding channel 14. Specifically, the pushing element is rotatably disposed on the support 21, and the support 21 can reciprocate along a direction from an inlet to an outlet of the sample feeding channel 14, so that the pushing element can be movably disposed in the guide groove. Meanwhile, the pushing piece has a first state and a second state. The first state refers to the state that the pushing piece does not enter the sample feeding channel. The second state refers to the pushing piece is in the sample feeding channel. When the pushing element is in the first state, the pushing element abuts against the limiting plate 30 so that the pushing element leaves the sample feeding channel 14, and when the pushing element is in the second state, the pushing element leaves the limiting plate 30 so that the pushing element enters the sample feeding channel 14 under the urging of the elastic element. "the pusher abuts against the position-limiting plate 30 to make the pusher leave the sample channel 14" means that the pusher is not in the sample channel 14 or the pusher partially enters the sample channel 14 but does not affect the sample rack tray 200 carrying the sample rack 201 to enter the sample channel 14 when the pusher abuts against the position-limiting plate 30. "when the pusher is in the second state, the pusher leaves the position-limiting plate 30 so that the pusher enters the sample channel 14 under the urging of the elastic member" means that the pusher is out of abutment with the position-limiting plate 30.

In this embodiment, the first state refers to the sample channel 14, the pushing element does not enter the sample channel 14, and the pushing element abuts against the limiting plate 30, so as to limit the pushing element from rotating towards the sample channel 14; the second state refers to the pushing element entering the sample feeding channel 14.

The elastic element is arranged between the pushing element and the bracket 21 and is used for urging the pushing element, and when the pushing element is in the second state, the elastic element is used for driving the pushing element to rotate relative to the bracket 21, so that one part of the pushing element is positioned in the sample feeding channel 14 and the pushing element can abut against the sample rack 201 in the sample rack tray 200. The limiting plate 30 abuts against the pushing element in the first state of the pushing element, and is used for limiting the pushing element from rotating towards the sample feeding channel.

In the sample introduction device 100 provided in the embodiment of the present application, when the sample rack tray 200 with the sample rack 201 is not placed in the sample introduction channel 14, that is, the pushing assembly 20 is in the initial state, at this time, the limiting plate 30 limits the pushing member to rotate towards the sample introduction channel 14, and the pushing member is located in the guide groove. Thus, when the sample rack tray 200 with the sample rack 201 is required to be placed in the sample channel 14, the sample rack tray is easily placed in the sample channel 14 due to the fact that the pushing piece is located in the guide groove, blocking of the sample rack 201 by the pushing piece is avoided, and the sample rack tray 200 and the sample rack 201 on the sample rack tray are convenient to place.

As shown in fig. 1 to 4, in the present embodiment, the guide grooves are provided on both sides of the sample channel 14, but of course, the guide grooves may be provided on one side of the sample channel 14. The number of guide grooves is two, and the guide grooves are a first guide groove 15 and a second guide groove 16. In particular, the sample channel 14 comprises a bottom 13, a first side wall 11 and a second side wall 12 of the cartridge, i.e. the bottom 13, the first side wall 11 and the second side wall 12 of the cartridge form the sample channel 14. Optionally, the first side wall 11 and the second side wall 12 are disposed parallel to each other, the first guide slot 15 is opened on the first side wall 11, and the second guide slot 16 is opened on the second side wall 12.

It will be understood that, correspondingly, the pushers are exemplified by two, each of which is selected to use a push plate, the two push plates being a first push plate 22 and a second push plate 23, respectively. Two corresponding elastic members are also provided, namely a first elastic member 24 and a second elastic member 25. Two limiting plates 30 are also provided, namely a first limiting plate and a second limiting plate (not shown in the figure).

Specifically, the first push plate 22 and the second push plate 23 are respectively rotatably disposed in the support 21, and the support 21 can reciprocate along a direction from the inlet 141 to the outlet 142 of the sample channel 14, so that the first push plate 22 can be movably disposed in the first guide groove 15, and the second push plate 23 can be movably disposed in the second guide groove 16.

The first elastic member 24 is disposed between the first push plate 22 and the bracket 21, and the second elastic member 25 is disposed between the second push plate 23 and the bracket 21. When the pushing element is in the second state, the first elastic element 24 is used to drive the first pushing plate 22 to rotate relative to the bracket 21, and the second elastic element 25 is used to drive the second pushing plate 23 to rotate relative to the bracket 21, so that a part of the first pushing plate 22 and the second pushing plate 23 is located in the sample channel 14. When the pushing element is in the first state, the first limiting plate is used for limiting the first pushing plate 22 to rotate towards the sample feeding channel 14, and the second limiting plate is used for limiting the second pushing plate 23 to rotate towards the sample feeding channel 14.

Specifically, when the pushing element is in the first state, the first elastic element 24 and the second elastic element 25 are respectively in a compressed state, the first limiting plate limits the first pushing plate 22 to rotate towards the sample channel 14, and the second limiting plate limits the second pushing plate 23 to rotate towards the sample channel 14. At this time, the first and second push plates 22 and 23 are respectively located in the first and second guide grooves 15 and 16. Thus, when the sample rack tray 200 with the sample rack 201 is required to be placed in the sample channel 14, the first push plate 22 and the second push plate 23 are correspondingly located in the first guide groove 15 and the second guide groove 16, so that the sample rack tray 200 can be easily placed in the sample channel 14, the sample rack 201 is prevented from being blocked by the first push plate 22 and the second push plate 23, and the sample rack tray 200 and the sample rack 201 thereon can be conveniently placed.

After the sample rack tray 200 with the sample rack 201 is placed in the sample channel 14, the driving bracket 21 moves a preset distance in the first direction, and at this time, the first and second limiting plates release the limitation on the first and second pushing plates 22 and 23, respectively. The first elastic member 24 and the second elastic member 25 are restored from the compressed state to a non-elastically deformed state (normal state), so that the first elastic member 24 drives the first push plate 22 to rotate toward the sample channel 14 by a predetermined angle, and the second elastic member 25 drives the second push plate 23 to rotate toward the sample channel 14 by a predetermined angle. If the sample rack 201 on the sample rack tray 200 is pushed to move in the first direction, the driving of the rack 21 is continued to move in the first direction, that is, the first push plate 22 and the second push plate 23 respectively move in the first direction along the first guide groove 15 and the second guide groove 16, and at this time, the first push plate 22 and the second push plate 23 can respectively abut against the sample rack 201. Thus, the first push plate 22 and the second push plate 23 are continuously driven to move towards the first direction, so that the sample rack 201 can move towards the first direction, the outlet 142 of the sample channel 14 of the sample rack 201 can be pushed out, and the sample rack 201 can be conveniently conveyed.

As shown in fig. 12 and 13, in the second state of the pushing member, when a new sample rack 201 is pushed by a person in the sample rack tray 200 by the first pushing plate 22 and the second pushing plate 23 toward the inlet 141 side of the sample injection channel 14, the new sample rack 201 is pushed, so that the new sample rack 201 pushes the first pushing plate 22 and the second pushing plate 23 to rotate in the direction toward the first guide groove 15 and the second guide groove 16, respectively, until the new sample rack 201 moves to the side of the first pushing plate 22 and the second pushing plate 23 away from the inlet 141 side of the sample injection channel 14. At this time, a new sample rack 201 is completely put on the sample rack tray 200.

The first elastic member 24 and the second elastic member 25 may be torsion springs, or the torsion springs may be elastic members having the same function, such as a tension spring, a spring, and a plate spring, which can pull the first push plate 22 and the second push plate 23 to move.

As shown in fig. 5, in some embodiments of the present application, a limit stop is disposed on the bracket 21, and the limit stop is used for limiting the push member to change from the second state to the first state. The limit baffle can be used for limiting the push piece to rotate towards the direction far away from the sample feeding channel 14 in the second state of the push piece, can limit the push piece to rotate towards the first direction, can also limit the push piece to rotate towards the first reverse direction, but does not simultaneously limit the push piece to rotate towards the first direction and the reverse direction of the first direction. In the description of fig. 5, two limit baffles are provided corresponding to the number of the guide grooves and the number of the pushing members. The two limit baffles are a first limit baffle 211 and a second limit baffle 212 respectively.

When the pushing member is in the second state, at this time, one side of the first pushing plate 22 and one side of the second pushing plate 23 can abut against the sample rack 201 on the sample rack tray 200 in the sample channel 14, and the other side of the first pushing plate 22 and the other side of the second pushing plate 23 respectively abut against the first limiting baffle 211 and the second limiting baffle 212 correspondingly. In this case, the first limit baffle 211 is used to limit the first push plate 22 to rotate in a direction away from the sample rack tray 200, and the second limit baffle 212 is used to limit the second push plate 23 to rotate in a direction away from the sample rack tray 200 and the sample injection channel 14. Thus, when the first and second push plates 22 and 23 push the sample rack 201, the first and second limit stoppers 211 and 212 can prevent the first and second push plates 22 and 23 from rotating in a direction away from the sample rack tray 200. At this time, as shown in fig. 10 and 11, the first limit stopper 211 and the second limit stopper 212 can prevent the first push plate 22 and the second push plate 23 from rotating in the opposite direction to the first direction.

Optionally, the support 21 includes bottom plate 213, riser, diaphragm and support, the riser sets up the one end of bottom plate, the one end of diaphragm with the riser is connected, the other end with limit baffle connects, just limit baffle with the diaphragm mutually perpendicular sets up, the support is fixed in on the limit baffle, push away the piece with the support rotates to be connected. If the number of the pushing members is two, the bracket 21 specifically includes a bottom plate 213, a first vertical plate 214, a second vertical plate 215, a first cross plate 216, a second cross plate 217, a first support 218, and a second support 219. The first riser 214 and the second riser 215 are fixed to opposite ends of the base plate 213. One end of the first transverse plate 216 is fixed on the first vertical plate 214, the other end is connected with the first limit baffle, one end of the second transverse plate 217 is fixed on the second vertical plate 215, the other end is connected with the second limit baffle, the first limit baffle and the first transverse plate 216 are perpendicular to each other, and the second limit baffle and the second transverse plate 217 are perpendicular to each other. The first support 218 is connected to the first limit baffle and is rotatably connected to the first push plate 22 via the first rotating shaft 60, one end of the torsion spring abuts against the first push plate 22, and the other end abuts against the first support 218. The second support 219 is connected with the second limit baffle, and is rotationally connected with the second push plate 23 through the second rotating shaft 61, one end of the torsion spring abuts against the second push plate 23, and the other end abuts against the second support 219.

As shown in fig. 5, in any of the above embodiments of the present application, optionally, the pushing assembly 20 further includes a rotating shaft, the pushing member is rotatably connected to the support through the rotating shaft, the elastic member is fixed on the rotating shaft, one end of the elastic member abuts against the pushing member, and the other end of the elastic member abuts against the support. Namely, one pushing piece is used corresponding to one rotating shaft.

Referring to fig. 5, two rotating shafts are taken as an example, and the two rotating shafts are a first rotating shaft 60 and a second rotating shaft 61 respectively. The first push plate 22 is rotatably connected to the bracket 21 via the first rotating shaft 60, and the second push plate 23 is rotatably connected to the second support 219 via the second rotating shaft 61. The first elastic member 24 is fixed on the first rotating shaft 60, one end of the first elastic member 24 abuts against the first push plate 22, and the other end abuts against the first support 218. The second elastic member 25 is fixed on the second rotating shaft 61, one end of the second elastic member 25 abuts against the second push plate 23, and the other end abuts against the second support 219. For example, when the first elastic member 24 and the second elastic member 25 select torsion springs, two torsion springs are sleeved on the first rotating shaft 60 and the second rotating shaft 61, one end of one torsion spring abuts against the first push plate 22, and the other end abuts against the first support 218. One end of the other torsion spring abuts on the second push plate 23, and the other end abuts on the second support 219.

In addition, the first push plate 22 is rotatably connected with the first support 218 through the first rotating shaft 60, and the second push plate 23 is rotatably connected with the second support 219 through the second rotating shaft 61, so that the connecting structure is simple, and the production, manufacturing and assembly are convenient.

As shown in fig. 4, in some embodiments of the present application, optionally, the pushing assembly 20 further includes a driving mechanism 26 and a transmission mechanism 27, and the transmission mechanism 27 includes a supporting frame 271, a transmission wheel 272 and a transmission belt 273. Specifically, the supporting frame 271 is fixed to the bottom 13 of the loading seat. The driving wheel 272 is rotatably disposed on the supporting frame 271 near one end of the outlet 142 of the sample feeding channel 14, and is in transmission connection with the output end of the driving mechanism 26 through the conveying belt 273. The bracket 21 is fixedly connected to the conveyor belt 273. Thus, when the driving mechanism 26 rotates, the output end of the driving mechanism 26 drives the conveyor belt 273 to move, and the conveyor belt 273 further drives the bracket 21 to move.

In this embodiment, the driving mechanism 26 drives the transmission mechanism 27 to transmit, so that the transmission mechanism 27 drives the support 21 to reciprocate in the first direction and the second direction, if the driving mechanism 26 rotates forward, the rotating mechanism drives the support 21 to move toward the first direction. The driving mechanism 26 is reversed, and the transmission mechanism 27 drives the bracket 21 to move towards the second direction. Thus, the pusher can be reciprocated along the guide grooves, i.e., the first and second push plates 22 and 23 are reciprocated along the first and second guide grooves 15 and 16, respectively. The driving mechanism 26 may be a driving source such as a motor or a stepping motor.

As shown in fig. 4, in the above embodiment of the present application, further, the transmission mechanism 27 further includes a sliding portion 275 and a guiding portion 274, the guiding portion 274 is fixed on the supporting frame 271, and the sliding portion 275 is fixed on the top of the bottom plate 213 and is connected with the guiding portion 274 in a sliding manner. In this embodiment, by the arrangement of the sliding portion 275 and the guide portion 274, the sliding portion 275 can be slidably connected with the guide portion 274 during the movement of the bracket 21, so as to increase the movement guidance and stability. Specifically, the sliding part 275 may be a slider fixed on the top of the bottom plate 213 of the rack 21, that is, the slider is fixed on the conveyor belt 273 by the bottom plate 213.

In this embodiment, the first detecting device 40 is used to detect whether the sample rack tray 200 is placed in the sample channel 14, and if so, a signal is sent to the driving mechanism 26, and the driving mechanism 26 drives the support 21 to move. Otherwise, no signal is sent to the drive mechanism 26. The first detecting device 40 may be a micro switch, or may be other detecting devices such as a pressure sensor and a hall element. For example, the first detecting device 40 is a microswitch, and a slider capable of pressing the microswitch is provided above the microswitch. The through hole of the sliding member passing through the bottom of the loading base 10 can contact with the bottom of the sample rack tray 200. When the sample rack tray 200 is placed in the sample channel 14, the bottom of the sample rack tray 200 presses the sliding member in the through hole, the sliding member presses the micro switch, and after the micro switch detects that the sample rack tray 200 is placed on the sample channel 14, the first push plate 22 and the second push plate 23 of the push assembly 20 move to the first direction, so that the sample rack 201 in the sample tray can be pushed to move along the sample channel 14.
