Referring to fig. 1 and 2, the present invention provides a sample rack transferring structure 100, where the sample rack transferring structure 100 is applied to a sample analyzer, and on one hand, provides a sample rack 200 for the sample analyzer, and on the other hand, can facilitate recovery of the sample rack 200 after sampling is completed, so as to ensure that the sample analyzer can continuously detect; moreover, the sample rack transport structure 100 may carry a sample rack 200 having sample containers, a user may load the sample rack 200 onto the sample rack transport structure 100 at a sample storage area, and then the user places the sample rack transport structure 100 onto a sample analyzer from the sample storage area with the sample rack transport structure 100, effecting transport of the sample rack 200. In particular, the sample rack transport structure 100 may carry a plurality of sample racks 200 arranged side by side, and each sample rack 200 may carry a plurality of sample containers thereon. Then, when the sample analyzer detects, the sample rack 200 is sent out from the sample rack transferring structure 100, the sample rack 200 and the sample container on the sample analyzer are conveyed to a designated sample sucking position by the sample conveying structure on the sample analyzer, and the sample in the sample container is sucked by the dispensing needle; after the sample on the sample rack 200 is sucked, the sample conveying structure conveys the sample rack 200 to the recycling place. In this embodiment, a sample rack transport structure 100 is also provided at the recycling location, facilitating the recycling and transport of the sample rack 200. It should be noted that the specific kind of the sample to be measured is not limited, and in some embodiments, the sample to be measured includes a solid sample or a liquid sample. It will be appreciated that the testing of a liquid sample may be performed by carrying the liquid sample in a container such as a test tube and placing it on the sample holder 200. Further liquid samples include, but are not limited to, blood samples.

In the present invention, the sample rack transport structure 100 includes a carrying tray 110 and a clamping mechanism 120. The carrying tray 110 serves as a carrying function for placing the sample rack 200. The carrying tray 110 has a placing cavity 114, the carrying tray 110 has an opening 115 communicating with the placing cavity 114 at one side of the placing cavity 114, the placing cavity 114 is used for carrying the sample racks 200 placed in a row, and the arrangement direction of the sample racks 200 extends toward the opening 115. Specifically, the carrying tray 110 includes a carrying bottom plate 113 and carrying baffles 112 surrounding three sides of the carrying bottom plate 113, the carrying bottom plate 113 and the carrying baffles 112 enclose the placing cavity 114, wherein two opposite carrying baffles 112 are denoted as carrying side plates 111, the opening 115 is formed between the two carrying side plates 111, and the opening 115 is opposite to the carrying baffles 112 between the two carrying side plates 111. The opening 115 is used to load reaction vessels into the carrying tray 110 or to remove sample vessels from the carrying tray 110.

It will be appreciated that the opening 115 is the entrance and exit of the sample rack 200 from the carrying tray 110 during operation of the sample analyzer. Specifically, the sample rack transport structure 100 carries the sample rack 200 of the sample storage area onto the sample analyzer, and the sample rack 200 enters the carrying tray 110 from the opening 115; in operation of the sample analyzer, the sample rack 200 may be fed out of the carrying tray 110 through the opening 115; the sample rack transport structure 100 recovers the sampled sample rack 200, and when the sample analyzer is in operation, the sampled sample rack 200 enters the carrying tray 110 through the opening 115; the sample rack transport structure 100 is removed from the sample analyzer and placed in a recovery site, and the sampled sample rack 200 is fed out of the carrying tray 110 through the opening 115.

The plurality of sample racks 200 are arranged in the placing cavity 114 along the connecting line direction of the bearing baffle 112 and the opening 115, and the positions of the sample racks 200 are limited by the bearing side plates 111 opposite to the two sides, so that the sample racks 200 are prevented from moving towards the outer sides of the bearing side plates 111, and the sample racks 200 are reliably limited in the bearing tray 110. Moreover, the loading barrier 112 opposite to the opening 115 can also limit the position of the sample rack 200 so that the loaded sample rack 200 can only abut against the loading barrier 112 at most, and the sample rack 200 is prevented from moving to the outside of the loading barrier 112.

Optionally, the carrying side plate 111 further has a guiding function, and correspondingly, the two ends of the sample rack 200 facing the carrying side plate 111 are respectively provided with a protruding part, after the sample rack 200 is loaded into the placing cavity 114, the sample rack 200 is lapped on the top of the carrying side plate 111 through the protruding parts on two sides, at this time, the sample rack 200 can be pushed, so that the sample rack 200 slides along the carrying side plate 111, and the loading and unloading of the sample rack 200 are guided and limited, so that the sample rack 200 is prevented from tilting in the placing cavity 114 to affect the loading of the sample rack 200, and the like. Of course, in other embodiments of the present invention, a guide protrusion or a guide groove may be provided on the loading base 113, and the guide protrusion or the guide groove extends along the connection line direction between the loading baffle 112 and the opening 115, and correspondingly, the bottom structure of the sample rack 200 is matched with the guide protrusion or the guide groove, so that loading and unloading of the sample rack 200 can be guided.

The clamping mechanism 120 is fixedly disposed on an inner sidewall of the carrying tray 110 and is disposed adjacent to the opening 115. I.e. the clamping mechanism 120 is arranged on the side of the carrying side plate 111 facing the placing cavity 114, facilitating the cooperation of the clamping mechanism 120 with the sample holder 200. The clamping mechanism 120 is used to effect locking of the sample rack 200. The clamping mechanism 120 is movably disposed on an inner sidewall of the carrying tray 110, and the clamping mechanism 120 can extend into the placement cavity 114 and contact an end of the sample rack 200 to clamp the sample rack 200. Accordingly, the clamping mechanism 120 may not clamp the sample rack 200, i.e., unlock the sample rack 200; specifically, the clamping mechanism 120 moves away from the placement cavity 114 and out of the end of the sample rack 200 to unlock the sample rack 200.

It will be appreciated that the clamping mechanism 120 has two modes of operation, one is to clamp the sample rack 200 to achieve a locking operation of the sample rack 200, and in particular, the clamping mechanism 120 may extend into the placement cavity 114 and contact an end of the sample rack 200 in the placement cavity 114 to achieve clamping of the sample rack 200, so that the sample rack 200 is reliably fixed in the placement cavity 114, and at this time, the sample rack 200 cannot move in the carrying tray 110, thereby avoiding sliding or tilting of the sample rack 200 during handling. The other is far away from the sample rack 200 to unlock the sample rack 200, specifically, the clamping mechanism 120 can move towards the outer side of the placement cavity 114 in a direction far away from the sample rack 200, so that the clamping mechanism 120 is separated from the sample rack 200 to unlock the sample rack 200, at this time, the sample rack 200 is not limited by the clamping mechanism 120 in the placement cavity 114, and the sample rack 200 can freely move in the placement cavity 114 to realize loading or unloading operation of the sample rack 200.

Moreover, the clamping and unlocking control with respect to the clamping mechanism 120 is achieved by the position of the sample rack transport structure 100. Illustratively, when the clamping mechanism 120 is constrained, the clamping mechanism 120 will move in a direction away from the sample holder 200 and gradually extend out of the placement cavity 114; when the holding mechanism 120 is unrestrained, the holding mechanism 120 moves toward the direction in which the sample holder 200 is located, gradually extending into the placement cavity 114. The limitation herein refers to limitation by a table, and it is understood that the table may be a location where the sample transport structure is placed for the sample analyzer, or may be a reference surface, such as a table, a platform, or the like, where the sample rack transport structure 100 is placed when loading or unloading the sample rack 200.

Specifically, when the sample rack transferring structure 100 leaves the table top, the clamping mechanism 120 loses the limitation of the table top, so that the clamping mechanism 120 can extend into the placing cavity 114 and contact with the end part of the sample rack 200, thereby realizing the clamping and fixing of the sample rack 200 and avoiding the movement of the sample rack 200 in the transferring process; when the sample rack transport structure 100 is positioned on a table top, the clamping mechanism 120 is limited by the table top, and the clamping mechanism 120 can move away from the placement cavity 114 to unlock the sample rack 200, so that the sample rack 200 can move in the placement cavity 114 to load or unload the sample rack 200. That is, when the sample rack transport structure 100 is lifted, the sample rack transport structure 100 may leave the table, and at this time, the clamping mechanism 120 loses the restriction to clamp the sample rack 200 on the carrying tray 110, so as to lock the sample rack 200; when the sample rack 200 transfer mechanism is lowered, i.e., the sample rack transfer structure 100 is placed on a table, the clamping mechanism 120 is restrained to move away from the sample rack 200 on the carrying tray 110, thereby unlocking the sample rack 200.

The present invention can achieve the clamping and unlocking of the sample rack 200 in the carrying tray 110 by lifting or lowering the sample rack transport structure 100. In this way, when a user uses the sample rack transfer structure 100 to transfer the sample rack 200, the user places the sample rack 200 on the table, and the clamping mechanism 120 moves in a direction away from the placement cavity 114, at this time, the clamping mechanism 120 does not limit the position of the sample rack 200, so that the sample rack 200 can be loaded into the carrying tray 110; after loading, a user lifts the sample rack transferring structure 100, and the clamping mechanism 120 can clamp and fix the sample rack 200 to realize transferring, so that the sample rack 200 is prevented from moving in the transferring process, and the problems of sample damage and the like caused by falling of the sample rack 200 from the bearing tray 110 are avoided; placing the sample rack transfer structure 100 on the sample analyzer, and unlocking the sample rack 200 by the clamping mechanism 120, wherein the sample rack 200 is sent out from the bearing tray 110, so that the sample rack 200 is conveyed; after the sample rack 200 is transported, the sample rack transport structure 100 may be lifted to reload the sample rack 200. It is understood that when the sample rack transport structure 100 recovers the sample rack 200 of the sampled sample container, the operation procedure is the same as the operation mode of the sample rack transport structure 100, and will not be described in detail herein.

Moreover, after the clamping mechanism 120 unlocks the sample rack 200, the movement of the sample rack 200 can also be guided by the bearing side plates 111 on both sides of the bearing tray 110, so that the sample rack 200 can slide into and out of the placing cavity 114 along the bearing side plates 111, and loading and unloading of the sample rack 200 are realized. In addition, the sample rack transferring structure 100 of the invention realizes the locking and unlocking of the sample rack 200 through the clamping mechanism 120, and does not need to be manually locked and unlocked by a user, so that the sample rack transferring structure 100 has the advantages of simple structure, convenient operation and convenient use for the user, and meanwhile, the sample rack transferring structure 100 is light and handy after the clamping mechanism 120 is adopted, and the operation hand feeling of the user is improved.

Referring to fig. 1, 5 and 6, in the present embodiment, the clamping mechanism 120 includes a first clamping mechanism and a second clamping mechanism, and the first clamping mechanism and the second clamping mechanism are disposed on the inner sidewall of the carrying tray 110 opposite to each other. The first clamping mechanism and the second clamping mechanism can synchronously abut against two ends of the sample rack 200 to clamp the sample rack 200. That is, the sample rack transferring structure 100 of the present invention clamps the sample rack 200 by the cooperation of two oppositely disposed clamping mechanisms 120, so that the sample rack 200 is reliably fixed in the placement cavity 114 of the carrying tray 110, and the clamping and fixing of the sample rack 200 are realized. It can be appreciated that the first clamping mechanism and the second clamping mechanism move synchronously, and when locked, the first clamping mechanism and the second clamping mechanism can synchronously extend into the placing cavity 114 and respectively abut against two ends of the sample rack 200 so as to clamp the sample rack 200; when the sample rack 200 is unlocked, the first clamping mechanism and the second clamping mechanism can synchronously move towards a direction away from the placing cavity 114 and separate from the end parts of the sample rack 200, so as to unlock the sample rack 200. In this way, the two clamping mechanisms 120 move synchronously, so that the position of the sample rack 200 can be prevented from moving in the connecting line direction of the two bearing side plates 111, and the clamping and fixing reliability of the sample rack 200 can be ensured.

Of course, in other embodiments of the present invention, the number of the clamping mechanisms 120 may be one, the clamping mechanisms 120 are disposed on one of the bearing side plates 111, the clamping mechanisms 120 are matched with the other bearing side plate 111, and the clamping mechanisms 120 prop the sample rack 200 against the bearing side plate 111, so that the sample rack 200 is reliably fixed between the clamping mechanisms 120 and the bearing side plate 111, and thus the clamping fixation of the sample rack 200 can be realized.

Optionally, the sample rack transferring structure 100 further includes a handle 130, where the handle 130 is disposed on the carrying tray 110, and the handle 130 is used for carrying the carrying tray 110. When carrying the carrying tray 110, a user can realize the carrying tray through the handle 130, so that the carrying by the user is convenient. It can be appreciated that the handle 130 and the carrying tray 110 are in an integrated structure, so that reliability of carrying the carrying tray 110 by the handle 130 is ensured; of course, the handle 130 is detachably connected with the carrying tray 110, so as to meet different use requirements of users. Preferably, the number of the handles 130 is two, and the two handles 130 are symmetrically disposed at two ends of the carrying tray 110. When carrying the sample rack transferring structure 100, the user can directly lift the handle 130 to lift the carrying tray 110, so that the user can hold the carrying tray 110 conveniently.

Referring to fig. 1 to 4, in an embodiment of the present invention, the clamping mechanism 120 includes a clamping arm 121, a clamping rod 122 and an unlocking portion 123, wherein the clamping arm 121 is rotatably mounted in the carrying tray 110, and the clamping rod 122 and the unlocking portion 123 are located on the clamping arm 121. When the clamping arm 121 rotates under the action of gravity, the clamping arm 121 can drive the unlocking portion 123 to extend out of the carrying tray 110, and simultaneously, the clamping rod 122 extends into the placing cavity 114 and abuts against the sample rack 200, so as to clamp the sample rack 200. Correspondingly, when the unlocking part 123 receives a force towards the placing cavity 114, the unlocking part 123 retracts into the placing cavity 114, the unlocking part 123 can drive the clamping arm 121 to retract into the bearing tray 110, and the clamping rod 122 is separated from the sample rack 200. It should be noted that, the clamping arm 121 is in a lever structure, the clamping arm 121 further includes a rotating member, and the clamping arm 121 is rotatably mounted in the carrying tray 110 through the rotating member, and the rotating member is, for example, a structure for realizing rotation by a rotating shaft, a hinge, or the like. One end of the clamping arm 121 is a clamping rod 122 for being matched with the end part of the sample rack 200, and the other end of the clamping arm 121 is an unlocking part 123 for being matched with the table top. For example, the unlocking portion 123 is a protrusion provided at an end of the clamp arm 121, which facilitates unlocking control.

It will be appreciated that the clamping arm 121 is locked by gravity and unlocked by engagement with the table top. When the sample rack transferring structure 100 is lifted, the unlocking part 123 is separated from the table surface and loses the gravity action of the bearing tray 110, at this time, the clamping arm 121 drives the unlocking part 123 to reset and stretch out of the bearing tray 110 under the action of self gravity, and the clamping rod 122 stretches into the placing cavity 114, and the clamping rod 122 can be abutted with the end part of the sample rack 200 in the placing cavity 114, so that the sample rack 200 is clamped. When the sample rack transferring structure 100 is placed on the table top, the table top is in contact with the unlocking part 123, the gravity of the bearing tray 110 can cause the bearing tray 110 to act downwards due to the gravity action of the bearing tray 110, and the gravity of the bearing tray 110 can apply a reaction force to the unlocking part 123 through the table top, so that the clamping arm 121 drives the unlocking part 123 to retract into the bearing tray 110 under the gravity action of the bearing tray 110, and simultaneously, the clamping arm 121 drives the clamping rod 122 to move towards the direction away from the placing cavity 114 so as to separate from the end part of the sample rack 200, so that the sample rack 200 is unlocked. Of course, in other embodiments of the present invention, the unlocking or locking operation of the sample rack 200 may be performed by applying or withdrawing an external force to or from the unlocking portion 123.

Further, the clamping arm 121 includes a first arm 1211 and a second arm 1212 that are connected to each other, the connection portion between the first arm 1211 and the second arm 1212 is rotatably mounted on the carrier tray 110, and one ends of the first arm 1211 and the second arm 1212 that are far away from each other are away from each other and extend toward the direction in which the placement cavity 114 is located, the clamping rod 122 is located at an end of the first arm 1211, and the unlocking portion 123 is located at an end of the second arm 1212. The first arm 1211 drives the clamping lever 122 to extend into the placement cavity 114, and the second arm 1212 drives the unlocking portion 123 to extend from the bottom of the carrying tray 110. In this embodiment, an included angle exists between the first arm 1211 and the second arm 1212, one end of the first arm 1211 is connected to one end of the second arm 1212, the end of the other end of the first arm 1211 is provided with the clamping rod 122, the end of the other end of the second arm 1212 is provided with the unlocking portion 123, and the ends of the first arm 1211 and the second arm 1212 facing away from each other extend toward the inner side of the bearing side plate 111, and the first arm 1211 and the second arm 1212 are linked. Preferably, the angle between first arm 1211 and second arm 1212 ranges from 75 ° to 150 °. It will be appreciated that the carrying side plate 111 of the carrying tray 110 has a mounting space therein in which the clamp arm 121 is rotatably mounted, and that the side of the carrying side plate 111 facing the placing chamber 114 has an extension opening through which the clamp lever 122 extends into the placing chamber 114 or retracts from the placing chamber 114. The bottom of the carrying tray 110 has an unlocking opening, and the unlocking part 123 can be extended or retracted from the bottom of the carrying tray 110.

When the sample rack transferring structure 100 is lifted, the bottom of the carrying tray 110 is gradually far away from the table top, the first arm 1211 drives the unlocking part 123 to reset under the action of self gravity, and the carrying tray 110 extends out of the unlocking opening, meanwhile, the first arm 1211 and the second arm 1212 are linked, the second arm 1212 drives the clamping rod 122 to extend into the placing cavity 114 from the extending opening, and the clamping rod 122 can be abutted with the end part of the sample rack 200 in the placing cavity 114, so as to clamp the sample rack 200. When the sample rack transferring structure 100 is placed on the table top, the table top is in contact with the unlocking part 123, the first arm 1211 drives the unlocking part 123 to retract into the carrying tray 110 from the unlocking opening under the gravity action of the carrying tray 110, meanwhile, the first arm 1211 is linked with the second arm 1212, and the second arm 1212 drives the clamping rod 122 to move from the extending opening to a direction away from the placing cavity 114 so as to separate from the end of the sample rack 200, so that the sample rack 200 is unlocked.

Optionally, the clamping mechanism 120 further includes an elastic member 124, where the elastic member 124 is disposed in the carrying tray 110 and abuts against the carrying tray 110 and the clamping arm 121, and the elastic force of the elastic member 124 can make the clamping rod 122 always abut against the sample rack 200. The elastic member 124 can provide a pushing force so that the holding rod 122 of the holding arm 121 can be in a state of extending into the placement chamber 114, abutting against the end of the sample rack 200. That is, the elastic member 124 always keeps the clamp arm 121 in the clamped sample rack 200; when unlocking, the gravity of the carrying tray 110 is greater than the elastic force of the elastic member 124, at this time, the unlocking part 123 pushes the first arm 1211 to move upwards, the first arm 1211 is linked with the second arm 1212, and the second arm 1212 drives the clamping rod to separate from the sample rack 200; when clamping, after the unlocking part 123 loses the gravity action of the carrying tray 110, the second arm 1212 drives the clamping rod 122 to extend into the placing cavity 114 to abut against the sample rack 200 under the gravity action of the clamping arm 121 and the thrust action of the elastic member 124, the second arm 1212 is linked with the first arm 1211, and the first arm 1211 drives the unlocking part 123 to extend out of the bottom of the carrying tray 110. The elastic member 124 is an elastic structure such as a torsion spring, a tension spring, a compression spring, and the like.

Referring to fig. 5, in another embodiment of the present invention, the lifting handle 130 is disposed in the carrying tray 110 in a liftable manner, the clamping mechanism 120 includes a clamping rod 122', and the bottom of the lifting handle 130 has an inclined surface, and the inclined surface is inclined toward the direction of the placement cavity 114 and abuts against the clamping rod 122'. The angled surface enables at least a portion of the clamping bar 122' to extend into the placement cavity 114 to clamp the sample rack 200 when the handle 130 is lifted. As the handle 130 is lowered, the clamping bar 122' can move away from the placement cavity 114 to disengage the sample rack 200. That is, when the handle 130 is lifted, the inclined surface at the bottom of the handle 130 can apply an upward force to the clamping rod 122', so that the clamping rod 122' can at least partially extend into the placing cavity 114 to abut against the sample rack 200, and locking of the sample rack 200 is achieved; when the handle 130 is put down, the inclined surface at the bottom of the handle 130 is lowered, so that the clamping rod 122 'returns to the initial position, and at this time, the clamping rod 122' is separated from the sample rack 200, so that the sample rack 200 is unlocked.

Specifically, in one implementation of the present embodiment, the clamping lever 122 'is rotatably disposed in the carrying tray 110, and the rotation axis of the clamping lever 122' is eccentrically disposed. When the handle 130 is lifted, the inclined surface drives the clamping rod 122' to rotate around the axis, so that the clamping rod 122' partially stretches into the placing cavity 114 and clamps the sample rack 200, and when the handle 130 is lowered, the inclined surface drives the clamping rod 122' to rotate around the axis, so that the clamping rod 122″ slides out of the placing cavity 114 to unlock the sample rack 200. That is, the clamping rod 122' is eccentrically disposed, when the sample rack transferring structure 100 is lifted, the lifting handle 130 is lifted and drives the inclined surface at the bottom to lift, and the inclined surface can drive the clamping rod 122' to eccentrically rotate, so that the eccentric large end of the clamping rod 122' rotates to the position that the placing cavity 114 is abutted with the end of the sample rack 200, thereby locking the sample rack 200; when the sample rack transfer structure 100 is put down, the lifting handle 130 descends and drives the inclined surface at the bottom to descend, and the inclined surface can drive the clamping rod 122 'to eccentrically rotate, so that the eccentric large end of the clamping rod 122' rotates out of the placing cavity 114 to separate from the end part of the sample rack 200, and unlocking of the sample rack 200 is achieved. Of course, the clamping lever 122' may be a cam structure. Moreover, the bottom of the handle 130 is provided with a wedge 131, and the inclined surface of the wedge 131 forms the inclined surface, however, an inclined plate or the like may be provided.

Of course, in another implementation of the present embodiment, the clamping mechanism 120 further includes a guide rail (not shown) disposed in the carrying tray 110, and the clamping rod 122' is slidably disposed on the guide rail; the guide sliding rail is horizontally arranged, or the guide sliding rail is arranged along the inclined direction vertical to the inclined surface. When the handle 130 is lifted, the inclined surface slides the clamping rod 122' into the placing cavity 114 along the guiding sliding rail so as to clamp the sample rack 200; when the handle 130 is lowered, the inclined surface slides the clamping bar 122' out of the placement cavity 114 along the guide rail to unlock the sample rack 200. That is, the handle 130 drives the clamping rod 122' to slide into or out of the placing cavity 114 along the guiding sliding rail through the inclined surface to lock and unlock the sample rack 200.

When the sample rack transferring structure 100 is lifted, the lifting handle 130 is lifted and drives the inclined surface at the bottom to lift, and the inclined surface can drive the clamping rod 122 'to slide out along the guide sliding rail, so that the clamping rod 122' at least partially slides into the placing cavity 114 to be abutted with the end part of the sample rack 200, thereby realizing the locking of the sample rack 200; when the sample rack transfer structure 100 is put down, the lifting handle 130 descends and drives the inclined surface at the bottom to descend, and the inclined surface is separated from the clamping rod 122', at this time, the clamping rod 122' can slide out of the placing cavity 114 along the guiding sliding rail so as to separate from the end of the sample rack 200, so that unlocking of the sample rack 200 is realized.

Optionally, the clamping mechanism 120 further includes a restoring member disposed in the carrying tray 110 for connecting the carrying tray 110 and the clamping rod 122', and the restoring member is capable of generating a force for moving the clamping rod 122' away from the sample rack 200. The resetting piece is an elastic element such as a tension spring, a compression spring, an elastic rope and the like. It can be appreciated that when the clamping lever 122' locks the sample rack 200, the clamping lever 122' drives the elastic member 124 to be in a stretched state, so that the clamping lever 122' can abut against the end of the sample rack 200; when the clamping lever 122 'unlocks the sample rack 200, the elastic member 124 drives the clamping lever 122' to be at an initial position away from the sample rack 200. Specifically, when the sample rack transferring structure 100 is lifted, the lifting handle 130 is lifted and drives the inclined surface at the bottom to lift, and the inclined surface can drive the clamping rod 122 'to overcome the elastic force of the reset piece, so that the clamping rod 122' at least partially slides into the placing cavity 114 to abut against the end part of the sample rack 200, thereby realizing locking of the sample rack 200; when the sample rack transfer structure 100 is put down, the lifting handle 130 descends and drives the inclined surface at the bottom to descend, the inclined surface is separated from the clamping rod 122', and the clamping rod 122' resets and slides out of the placing cavity 114 under the action of the elastic force of the resetting piece so as to separate from the end part of the sample rack 200, so that the unlocking of the sample rack 200 is realized.

Referring to fig. 6, in yet another embodiment of the present invention, the sample rack transferring structure 100 further includes a handle 130, a brake member 140, and a transmission mechanism, wherein the brake member 140 is disposed on the handle 130, and the clamping mechanism 120 includes a clamping rod 122 ", and the brake member 140 is linked with the clamping rod 122" through the transmission mechanism. The brake member 140 moves the clamping bar 122 "through the transmission mechanism, so that the clamping bar 122" extends into the placing cavity 114 to clamp the sample holder 200. The brake member 140 is in this embodiment a hand brake. When the sample rack transferring structure 100 is lifted, a user grips the braking part 140 while grabbing the lifting handle 130, and the braking part 140 drives the clamping rod 122 'to move through the transmission mechanism, so that the clamping rod 122' stretches into the placing cavity 114 to be abutted with the end part of the sample rack 200, so as to clamp the sample rack 200, and lock the sample rack 200 is realized; when the sample rack transfer structure 100 is put down, the user releases the handle 130 and releases the brake component 140, at this time, the brake component 140 is reset, and drives the clamping rod 122 "to reset through the transmission mechanism, at this time, the clamping rod 122" can move towards a direction away from the placing cavity 114, so that the clamping rod 122 "is separated from the end of the sample rack 200, and the unlocking of the sample rack 200 is realized. By way of example, the transmission mechanism may be a wire transmission mechanism, a link transmission mechanism, or the like capable of achieving linkage of the clamp lever 122″ with the brake member 140.

Referring to fig. 1-6 and 9, alternatively, the clamping bar 122 is made of a flexible material. In this way, the acting force of the contact between the clamping rod 122 and the sample rack 200 can be increased, the sample rack 200 is prevented from sliding off from the clamping rod 122, and the sample rack 200 is ensured to be fixed reliably. Alternatively, the clamping bar 122 is made of an elastically deformable material, such as a silicone material or a hard elastic material, etc. In this way, the acting force of the contact between the clamping rod 122 and the sample rack 200 can be increased, so that the sample rack 200 is prevented from slipping from the clamping rod 122, and the sample rack 200 is ensured to be fixed reliably. Alternatively, the clamping rod 122 may be made of a material with a high friction coefficient, so as to increase the friction force at the contact position of the sample rack 200 and the clamping rod 122, avoid the sample rack 200 from sliding off the clamping rod 122, and ensure that the sample rack 200 is fixed reliably.

Still alternatively, the clamping bar 122 has a plurality of engaging portions thereon, and the plurality of engaging portions are respectively engaged with the fixing portions 210 at the end of the sample rack 200. The shape of the mating portion is adapted to the fixing portion 210. Thus, after the sample rack 200 is mounted on the loading tray 110, the fixing portion 210 of the sample rack 200 can be engaged with the engaging portion, further improving the reliability of fixing the sample rack 200. Illustratively, the fixing portion 210 is a protrusion, and the mating portion is a recess; of course, the fixing portion 210 may be a groove, and the mating portion may be a protrusion.

Still alternatively, the clamping mechanism 120 further includes a clamping sleeve 125, where the clamping sleeve 125 is sleeved on the outer side of the clamping rod 122, and the clamping sleeve 125 is made of a flexible material. That is, the clamping bar 122 is in contact with the end of the sample rack 200 through the clamping sleeve 125. To ensure reliable contact of the clamping sleeve 125 with the sample holder 200, the clamping sleeve 125 is made of a flexible material. In this way, the acting force of the contact between the clamping rod 122 and the sample rack 200 can be increased, the sample rack 200 is prevented from sliding off from the clamping rod 122, and the sample rack 200 is ensured to be fixed reliably.

Further, the clamping sleeve 125 has a plurality of positioning portions 1251 disposed at intervals, and the plurality of positioning portions 1251 are respectively engaged with the fixing portions 210 at the end of the sample holder 200; the positioning portion 1251 is shaped to fit the fixing portion 210. In this way, after the sample rack 200 is mounted on the carrying tray 110, the fixing portion 210 of the sample rack 200 can be engaged with the positioning portion 1251, further improving the reliability of fixing the sample rack 200. Illustratively, the securing portion 210 is a protrusion and the positioning portion 1251 is a recess; of course, the fixing portion 210 may be a groove, and the positioning portion 1251 may be a protrusion. In this embodiment, the fixing portion 210 is a protrusion, the positioning portion 1251 is a groove, and the plurality of fixing portions 210 are disposed on the clamping sleeve 125 at intervals, and can cooperate with the grooves disposed on the sample rack 200 at intervals, so as to ensure that the sample rack 200 is reliably locked.

Optionally, the clamping sleeve 125 is made of an elastically deformable material, such as a silicone material or a hard elastic material, etc. In this way, the acting force of the contact between the clamping rod 122 and the sample rack 200 can be increased, so that the sample rack 200 is prevented from slipping from the clamping rod 122, and the sample rack 200 is ensured to be fixed reliably. Alternatively, the clamping sleeve 125 may be made of a material with a high friction coefficient, so as to increase the friction force at the contact position of the sample rack 200 and the clamping rod 122, avoid the sample rack 200 from slipping from the clamping rod 122, and ensure that the sample rack 200 is reliably fixed.

Referring to fig. 1, 7 and 8, as an embodiment, the sample rack transferring structure 100 further includes an anti-disengaging mechanism 150 and an unlocking mechanism 160, the anti-disengaging mechanism 150 is disposed on an inner sidewall of the carrying tray 110, the anti-disengaging mechanism 150 is close to the opening 115, and the anti-disengaging mechanism 150 is used for preventing the sample rack 200 from sliding out of the carrying tray 110; the unlocking mechanism 160 is disposed on the sample analyzer, and is used for unlocking the anti-disengaging mechanism 150. The anti-drop mechanism 150 is disposed at one end of the carrying side plate 111 away from the carrying baffle 112, and the anti-drop mechanism 150 plays a role in blocking, so as to prevent the sample rack 200 from sliding out of the placing cavity 114 of the carrying tray 110 during the transferring process of the sample rack transferring structure 100. Moreover, the anti-disengaging mechanism 150 is close to the opening 115, so that the sample racks 200 can be prevented from sliding out, the maximum number of sample racks 200 can be ensured to be loaded, and the transfer efficiency can be improved. After the anti-drop mechanism 150 is locked, the sample rack 200 cannot slide out of the placement cavity 114, and the sample rack 200 cannot be loaded into the placement cavity 114. The unlocking mechanism 160 can unlock the anti-disengaging mechanism 150, and after unlocking, the sample rack 200 in the placement chamber 114 can be unloaded, and the sample rack 200 can also be placed in the placement chamber 114.

When the carrying tray 110 is lifted, the anti-disengaging mechanism 150 can extend into the placement cavity 114 to limit the sample rack 200 from sliding out of the placement cavity 114. The carrying tray 110 is placed on the sample analyzer, and the unlocking mechanism 160 is engaged with the anti-release mechanism 150, and the anti-release mechanism 150 unlocks the sample rack 200. The carrying tray 110 is placed on the table top and the anti-drop mechanism 150 restricts the sample rack 200 from sliding out of the placement cavity 114. It can be understood that the unlocking mechanism 160 is disposed on the sample analyzer, that is, only when the sample rack transferring structure 100 is disposed on the sample analyzer, the anti-disengaging mechanism 150 can be matched with the unlocking mechanism 160, so as to unlock the anti-disengaging mechanism 150; at the same time, the clamping mechanism 120 is also in an unlocked state, at which time the sample rack 200 can be loaded into the carrying tray 110 or unloaded from the carrying tray 110. When the sample rack 200 transfer mechanism is lifted, the anti-disengaging mechanism 150 can extend into the placement cavity 114 and flank the sample rack 200, while the clamping mechanism 120 extends into the placement cavity 114 to contact the sample rack 200 to limit the position of the sample rack 200 so that the sample rack 200 is reliably secured in the placement cavity 114. When the sample rack transferring structure 100 is temporarily stored at the table top, the clamping mechanism 120 is unlocked, and the anti-disengaging mechanism 150 is still in a locked state due to the absence of the unlocking mechanism 160 on the table top, so as to prevent the sample rack 200 from sliding out of the placing cavity 114, and further improve the safety performance of the sample rack 200.

Specifically, when the sample rack transfer structure 100 is located on the sample analyzer, the anti-disengaging mechanism 150 is acted on by the unlocking mechanism 160 on the sample analyzer, so that the anti-disengaging mechanism 150 can move in a direction away from the placement cavity 114, to unlock the sample rack 200, so that the sample rack 200 can slide into or out of the placement cavity 114 to load or unload the sample rack 200. When the sample rack transfer structure 100 leaves the sample analyzer, the anti-falling mechanism 150 loses the effect of the unlocking mechanism 160, so that the anti-falling mechanism 150 can extend into the placing cavity 114 and be positioned at one side of the sample rack 200 to limit the position of the sample rack 200 and prevent the sample rack 200 from sliding out of the placing cavity 114; when the sample rack transport structure 100 is placed on the table top, no unlocking mechanism 160 on the table top is matched with the sample rack 200, and the anti-disengaging mechanism 150 is still positioned in the placing cavity 114 to limit the sample rack 200. That is, when the sample rack transport structure 100 is lifted, the sample rack transport structure 100 may be separated from the sample analyzer, and at this time, the anti-disengaging mechanism 150 can limit the position of the sample rack 200 on the carrying tray 110; when the sample rack 200 transfer mechanism is placed on the sample analyzer, the anti-disengaging mechanism 150 is now acted upon by the unlocking mechanism 160 to unlock the sample rack 200 away from the sample rack 200 on the carrying tray 110. When the sample rack transport structure 100 is placed on a table, the anti-drop mechanism 150 is still able to limit the position of the sample rack 200 on the carrying tray 110.

Moreover, when the sample rack 200 is loaded in the sample storage area of the sample rack 200, the area may also be provided with an unlocking mechanism 160, which can facilitate loading of the sample rack 200 from the opening 115 onto the carrying tray 110; of course, in other embodiments of the invention, the sample rack 200 may also be placed directly into the placement cavity 114 from the upper region of the carrying tray 110.

The invention can realize the limit and the unlock of the sample rack 200 in the bearing tray 110 by lifting or lowering the sample rack transferring structure 100. In this way, when a user uses the sample rack transfer structure 100 to transfer the sample rack 200, the sample rack 200 is placed on the sample analyzer, and the anti-drop mechanism 150 moves in a direction away from the placement cavity 114, at this time, the anti-drop mechanism 150 does not limit the position of the sample rack 200, and the sample rack 200 can be loaded into the carrying tray 110 or unloaded; the user lifts the sample rack transferring structure 100, the anti-disengaging mechanism 150 can limit the position of the sample rack 200 to realize transferring, so that the sample rack 200 is prevented from sliding out of the placing cavity 114 in the transferring process, and the problems of sample damage and the like caused by falling of the sample rack 200 from the bearing tray 110 are avoided; the sample rack transport 100 is placed onto the sample analyzer and the clamping mechanism 120 unlocks the sample rack 200. It should be understood that, when the sample rack 200 transferring mechanism is used for recycling the sample rack 200 of the sampled sample container, the operation procedure is the same as the operation mode of the sample rack transferring mechanism 100, and will not be described in detail herein.

Moreover, after the anti-disengaging mechanism 150 is unlocked, the movement of the sample rack 200 can also be guided by the bearing side plates 111 on both sides of the bearing tray 110, so that the sample rack 200 can slide into or slide into the slide groove placing cavity 114 along the bearing side plates 111, and loading and unloading of the sample rack 200 are realized. In addition, the sample rack transferring structure 100 of the invention realizes the limit and the unlock of the sample rack 200 through the anti-disengaging mechanism 150, and does not need a user to manually limit and unlock, so that the sample rack transferring structure 100 has the advantages of simple structure, convenient operation and convenient use for the user, and meanwhile, after the clamping mechanism 120 is adopted, the sample rack transferring structure 100 is light and handy, and the operation hand feeling of the user is improved.

As an embodiment, the anti-disengaging mechanism 150 includes a first anti-disengaging mechanism and a second anti-disengaging mechanism, and the first anti-disengaging mechanism and the second anti-disengaging mechanism are disposed on the inner sidewall of the bearing tray 110. The first and second anti-slip mechanisms can be in synchronous contact with or away from the sample rack 200. That is, the sample rack transfer structure 100 of the present invention blocks the sample rack 200 by the cooperation of the two oppositely disposed anti-disengaging mechanisms 150 to restrain the sample rack 200 in the placement cavity 114 of the carrying tray 110, thereby preventing the sample rack 200 from sliding out of the placement cavity 114. It can be appreciated that the first anti-falling mechanism and the second anti-falling mechanism move synchronously, and when locked, the first anti-falling mechanism and the second anti-falling mechanism can synchronously extend into the placing cavity 114 and are respectively positioned at the side surfaces of the sample rack 200 so as to limit the position of the sample rack 200; when the sample rack 200 is unlocked, the first and second anti-drop mechanisms can synchronously move towards the direction away from the placement cavity 114, and retract the carrying tray 110, and at this time, the anti-drop mechanism 150 is not limiting the sample rack 200. This prevents the sample rack 200 from sliding out of the placement cavity 114 by the synchronized movement of the two anti-disengaging mechanisms 150.

Of course, in other embodiments of the present invention, the number of the anti-disengaging mechanisms 150 may be one, and the anti-disengaging mechanisms 150 are disposed on one of the bearing side plates 111, so that the position of the sample rack 200 is limited by blocking one end of the sample rack 200, thereby limiting the sample rack 200.

As an embodiment, the anti-disengaging mechanism 150 includes a limiting arm 151, where the limiting arm 151 is rotatably installed in the carrying tray 110, and the limiting arm 151 has an opposite shielding plate 152 and a contact portion 153. The shielding plate 152 can contact with the sample rack 200 or be away from the sample rack 200, and the contact portion 153 is located in the carrying tray 110; when unlocked, the unlocking mechanism 160 can extend into the bearing tray 110 and contact the contact portion 153; when the lock is locked, the unlocking mechanism 160 is separated from the contact portion 153, and the limiting arm 151 rotates under the action of gravity and drives the shielding plate 152 to extend into the placing cavity 114 to be located at one side of the sample rack 200, so as to limit the position of the sample rack 200. It will be appreciated that after the shutter 152 extends into the placement cavity 114, the shutter 152 is positioned on the side of the sample holder 200 adjacent to the opening 115 and on the side of the sample holder 200 adjacent to the opening 115. This ensures a shielding effect of the shielding plate 152, and prevents the sample holder 200 from slipping out of the placement chamber 114. It can be appreciated that when the anti-release mechanism 150 is locked and unlocked, the contact portion 153 is always located in the bearing tray 110, and the unlocking operation is achieved by matching the contact portion 153 extending into the bearing tray 110 through the unlocking mechanism 160, so that after locking, if the unlocking mechanism 160 is not matched, the anti-release mechanism 150 cannot be unlocked, and the reliability of the limiting of the anti-release mechanism 150 is ensured.

Specifically, the limiting arm 151 is also of a lever structure, when the sample rack transferring structure 100 is lifted, the end portion of the carrying tray 110 is gradually far away from the table surface, the limiting arm 151 drives the contact portion 153 to reset under the action of self gravity, and meanwhile, the limiting arm 151 drives the shielding plate 152 to extend into the placing cavity 114, and the shielding plate 152 is located on one side of the sample rack 200 in the placing cavity 114, so that the limiting of the sample rack 200 is blocked. When the sample rack transfer structure 100 is placed on the sample analyzer, the unlocking mechanism 160 can extend into the bearing tray 110 to contact with the contact portion 153, so that the contact portion 153 moves and drives the limiting arm 151 to move, and meanwhile, the limiting arm 151 drives the shielding plate 152 to move in a direction away from the placement cavity 114 to be away from the sample rack 200, so that unlocking of the shielding plate 152 is achieved. When the sample rack transport structure 100 is placed on the table top, no corresponding unlocking mechanism 160 on the table top contacts the contact portion 153 of the anti-release mechanism 150 in the carrying tray 110, and the anti-release mechanism 150 is still in a locked state.

Optionally, the anti-disengaging mechanism 150 further includes an elastic member 154, where the elastic member 154 is disposed in the carrying tray 110 and abuts against the carrying tray 110 and the limiting arm 151, respectively. The elastic member 154 can provide a pushing force so that the shielding plate 152 of the stopper arm 151 can be in a state of being extended into the placement chamber 114, on one side of the sample rack 200. That is, the elastic member 154 always positions the limiting arm 151 at one side of the sample rack 200; when unlocking, the pushing force of the unlocking mechanism 160 is greater than the elastic force of the elastic piece 154, at this time, the contact portion 153 pushes the limiting arm 151 to move upwards, and drives the shielding plate 152 to be far away from the sample rack 200; when clamping, after the contact portion 153 loses the thrust action of the unlocking mechanism 160, the limiting arm 151 drives the shielding plate 152 to extend into the placing cavity 114 and be located at one side of the sample rack 200 under the gravity action of the limiting arm 151 and the thrust action of the elastic member 154, and meanwhile drives the contact portion 153 to move downwards for resetting. The elastic member 154 is an elastic structure such as a torsion spring, a tension spring, a compression spring, and the like.

Moreover, in one embodiment, the unlocking mechanism 160 includes an unlocking protrusion; when the anti-release mechanism 150 is unlocked, the unlocking protrusion extends into the bearing tray 110 to contact with the contact portion 153, so that the limiting arm 151 drives the shielding plate 152 to be away from the sample rack 200. When the sample rack transferring structure 100 is placed on the sample analyzer, the unlocking mechanism 160 corresponds to the anti-disengaging mechanism 150, and the unlocking protrusion can extend into the bearing tray 110 and contact with the contact portion 153 of the anti-disengaging mechanism 150, so as to provide thrust for the contact portion 153, and the limiting arm 151 drives the shielding plate 152 to move towards a direction away from the sample rack 200, so that unlocking of the anti-disengaging mechanism 150 is realized. After the sample frame transferring structure 100 is lifted, the anti-disengaging mechanism 150 is separated from the unlocking protrusion, and the limiting arm 151 drives the shielding plate 152 to extend into the placing cavity 114 to be located on one side of the sample frame 200 under the action of self gravity, so that the limiting of the sample frame 200 is realized.

In another embodiment, the unlocking mechanism 160 includes a pusher; when the anti-release mechanism 150 is unlocked, the pushing member extends out and into the carrying tray 110 to contact with the contact portion 153, so that the limiting arm 151 drives the shielding plate 152 to be away from the sample rack 200. When the sample rack transferring structure 100 is placed on the sample analyzer, the unlocking mechanism 160 corresponds to the anti-disengaging mechanism 150, and the pushing member stretches into the bearing tray 110 and contacts with the contact portion 153 of the anti-disengaging mechanism 150, so as to provide thrust for the contact portion 153, and the limiting arm 151 drives the shielding plate 152 to move towards a direction away from the sample rack 200, so that unlocking of the anti-disengaging mechanism 150 is realized. After the sample frame transferring structure 100 is lifted, the anti-disengaging mechanism 150 is separated from the pushing piece, and the limiting arm 151 drives the shielding plate 152 to extend into the placing cavity 114 to be located on one side of the sample frame 200 under the action of self gravity, so that the limiting of the sample frame 200 is realized. The pushing piece is an electric push rod or a telescopic rod and other structures.

In yet another embodiment, the unlocking mechanism 160 includes a magnetic member capable of attracting the shielding plate 152; when the anti-release mechanism 150 is unlocked, the magnetic member attracts the shielding plate 152, causing the shielding plate 152 to move away from the sample holder 200. It will be appreciated that the magnetic element is provided on the sample analyzer and can cooperate with the shielding plate 152 of the anti-drop mechanism 150 on the side of the carrier tray 110. When the sample rack transport structure 100 is placed on the sample analyzer, the unlocking mechanism 160 corresponds to the anti-disengaging mechanism 150, and the magnetic member can adsorb the shielding plate 152 in the carrying tray 110 to move towards the direction away from the placing cavity 114, so as to unlock the anti-disengaging mechanism 150. After the sample frame transferring structure 100 is lifted, the magnetic force between the anti-disengaging mechanism 150 and the magnetic piece disappears, and the limiting arm 151 drives the shielding plate 152 to extend into the placing cavity 114 to be located on one side of the sample frame 200 under the action of self gravity, so that the limiting of the sample frame 200 is realized. The magnetic member is exemplified by a magnet or the like.
