[0007] Beneficial effects: This utility model provides a sample holder, which is formed by combining a base and a loading part connected to the base to form a sample holder capable of holding a sample tube. The base is set on a transport track for transportation, and a clamping structure formed by multiple wire springs is used to clamp a sample tube, so that sample tubes can be transported one by one using an independent sample holder. This sample holder is small in size and occupies little space, has high transportation flexibility in the transport track, and is convenient for high-speed sample processing.

[0008] In one alternative implementation, the multiple coil springs are arranged in a centrally symmetrical manner, with the spacing between adjacent coil springs being equal.

[0009] Beneficial effects: Multiple wire springs surround to form a clamping structure to stabilize and limit the sample tube, while also facilitating the quick placement and removal of the sample tube in the sample holder.

[0014] In one alternative embodiment, the edge of the protruding edge is provided with a clearance structure away from the inner wall of the conveying groove.

[0015] Beneficial effects: By setting a clearance structure away from the inner wall of the conveying trough at the edge of the protruding edge, positional interference between the protruding edge and the inner wall of the conveying trough is avoided, thus improving the smoothness of sample holder transportation in the conveying track.

[0016] In one optional embodiment, the conveying track is further provided with a track plate located above the conveying groove, and the base is further provided with a limiting groove located above the protrusion, the limiting groove being able to engage with the track plate.

[0051] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0052] The following is combined with Figures 1-8 The following describes embodiments of the present invention.

[0053] According to embodiments of the present invention, in one aspect, a sample holder is provided, such as... Figure 1 , Figure 2 , Figure 4 As shown, it includes: a base and a loading part 310.

[0054] The base can be placed in the transport track 100 to transport the sample holder; the loading part 310 is connected to the base; the loading part 310 includes a connecting seat 311 fixedly connected to the base, and a clamping structure fixedly connected to the connecting seat 311. The clamping structure includes multiple wire springs 312, and the inner circumference of the multiple wire springs 312 is used to clamp a sample tube.

[0055] In the above embodiment, a sample holder capable of holding a sample tube is formed by combining a base and a loading part 310 connected to the base. The base is placed on the transport track 100 for transportation, and a clamping structure formed by multiple wire springs 312 is used to clamp a sample tube. This allows for the independent transport of sample tubes one by one using an independent sample holder. This sample holder is small in size and occupies little space, has high transportation flexibility in the transport track 100, and is convenient for high-speed sample processing.

[0056] Specifically, such as Figure 2As shown, the loading section 310 is provided with a connecting seat 311 to provide an assembly position for fixed connection with the base, and a clamping structure is provided to clamp the sample tube to stably limit the sample tube on the loading section 310.

[0057] Furthermore, this embodiment does not limit the specific connection method between the base and the loading part 310. In one embodiment, the loading part 310 is integrally formed on the base; in another embodiment, the loading part 310 and the base are fixedly connected by a connector.

[0058] Furthermore, this embodiment does not limit the specific connection method between the clamping structure and the connecting seat 311. In one embodiment, the clamping structure is integrally formed on the connecting seat 311; in another embodiment, the clamping structure and the connecting seat 311 are fixedly connected by a connector.

[0059] In some embodiments, such as Figure 4 , Figure 5 As shown, multiple coil springs 312 are arranged in a centrally symmetrical manner, and the spacing between two adjacent coil springs 312 is equal.

[0060] In the above embodiment, multiple wire springs 312 surround to form a clamping structure to stabilize and limit the sample tube, while facilitating the quick placement and removal of the sample tube in the sample holder.

[0061] Specifically, such as Figure 4 , Figure 5 As shown, the sample tube loading space formed by multiple springs 312 can be adjusted according to the actual size of the sample tube. In this embodiment, a clamping structure is formed by eight springs 312, which avoids wasting material due to overly dense arrangement of springs 312, and also avoids ensuring the loading stability of the sample tube due to overly sparse arrangement of springs 312.

[0062] Furthermore, such as Figure 5 As shown, the included angle between two adjacent springs 312 tends to be 45°.

[0063] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the base has a mounting position, and the loading part 310 has a screw hole 313. The mounting position and the screw hole 313 are connected by a screw 350.

[0064] In the above embodiment, the base and the mounting position of the loading part 310 are detachably connected by screws 350 in the screw hole 313 to facilitate the storage of the sample holder.

[0065] Specifically, such as Figure 2 , Figure 3 , Figure 4As shown, the connecting seat 311 of the loading part 310 is provided with a screw hole 313, and the inner cavity of the mounting seat 320 on the base is provided with a mounting position. The screw hole 313 and the mounting position are fastened by screws 350, thereby fixing the connecting seat 311 of the loading part 310 to the inner cavity of the mounting seat 320.

[0066] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the conveying track 100 is provided with a conveying groove 110, and the base is provided with a protruding edge 321. The protruding edge 321 can be embedded in the conveying groove 110 so that the base can move in a plane in the conveying track 100.

[0067] In the above embodiment, the transport track 100 and the base of the sample holder 300 are connected by a limiting fit through the transport groove 110 and the protrusion 321 to improve the stability of the transport of the sample holder 300.

[0068] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, along the extension direction of the conveying track 100, two conveying grooves 110 are arranged opposite each other on both sides of the conveying track 100. The two conveying grooves 110 are recessed in a direction away from the center line of the conveying track 100. The bottom of the sample holder 300 is provided with a protruding edge 321. The protruding edge 321 is arranged along the circumference of the base and protrudes in a direction away from the center line of the sample holder 300. The protruding edge 321 is fitted into the conveying groove 110, thereby realizing a limit of the conveying track 100 on the base of the sample holder 300.

[0069] Furthermore, such as Figure 1 As shown, the base can move in a planar manner in the conveying track 100. Specifically, the base can rotate in the conveying track 100 and can move in a straight line along the conveying track 100.

[0070] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the edge of the protruding edge 321 is provided with a clearance structure 322 that is away from the inner wall of the conveying groove 110.

[0071] In the above embodiment, a clearance structure 322 is provided at the edge of the protrusion 321 away from the inner wall of the conveying groove 110 to avoid positional interference between the protrusion 321 and the inner wall of the conveying groove 110, thereby improving the smoothness of the sample holder 300 in the conveying track 100.

[0072] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, the protruding edge 321 has two sides, upper and lower, and the avoidance structure 322 is provided on the outer edge of each of the upper and lower sides and is continuously provided along the entire circumference of the protruding edge 321.

[0073] Furthermore, the avoidance structure 322 is chamfered, with the chamfer angle being 30°-60°, preferably 45°.

[0074] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the conveying track 100 is also provided with a track plate 120 located on the upper part of the conveying groove 110, and the base is also provided with a limiting groove 323 located on the upper part of the protrusion 321, the limiting groove 323 can be fitted with the track plate 120.

[0075] In the above embodiment, the base of the transport track 100 and the sample holder 300 are connected by a limiting fit through the track plate 120 and the limiting groove 323 to further improve the stability of the transport of the sample holder 300.

[0076] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, along the extension direction of the conveying track 100, two track plates 120 are arranged opposite each other on both sides of the conveying track 100. The track plates 120 are also the upper edge of the conveying groove 110. The two track plates 120 protrude in the direction close to the center line of the conveying track 100. The limiting groove 323 on the sample holder 300 is arranged along the circumference of the base and is recessed in the direction close to the center line of the sample holder 300. The track plates 120 and the limiting groove 323 are fitted together to achieve another limiting of the base of the sample holder 300 by the conveying track 100.

[0077] In some embodiments, such as Figure 2 , Figure 3 As shown, the base includes: a mounting base 320, an electronic tag 330, and a mounting sleeve 340.

[0078] The mounting base 320 has an inner cavity, and the loading part 310 is fixedly connected to the inner cavity. The mounting base 320 has a protruding edge 321 and a limiting groove 323, as well as a side wall 324 located on the upper part of the limiting groove 323. The electronic tag 330 is located on the side wall 324. The mounting sleeve 340 is fixedly connected to the side wall 324 and located outside the electronic tag 330.

[0079] In the above embodiment, an electronic tag 330 is provided around the mounting base 320 to facilitate electronic identification and information reading, and a mounting sleeve 340 is provided on the outside of the electronic tag 330 to prevent the electronic tag 330 from directly contacting the external transmission structure, thus effectively protecting the electronic tag 330.

[0080] Specifically, such as Figure 2 , Figure 3 As shown, the electronic tag 330 is an RFID tag, and an identification device for identifying the electronic tag 330 is also provided on the outside of the driving device 200. After the electronic tag 330 is placed on the side panel 324, the electronic tag 330 is protected by a mounting sleeve 340 fixedly connected to the side panel 324 to prevent the electronic tag 330 from directly contacting the external transmission structure. At the same time, the mounting sleeve 340 can directly contact the external transmission structure to transmit the driving force of the external transmission structure to the base and the entire sample holder 300.

[0081] Furthermore, such as Figure 2 As shown, the mounting base 320 has a downwardly recessed inner cavity, and the lower part of the loading part 310 is fixedly connected to the inner cavity of the mounting base 320.

[0082] According to an embodiment of the present invention, another aspect also provides a sample holder driving assembly, such as... Figure 1 , Figure 6 , Figure 7 , Figure 8 It includes: a transport track 100, a drive device 200, and multiple sample holders 300 as described in the above embodiments.

[0083] The drive device 200 is located on the outside of the conveying track 100. The drive device 200 includes a stop member 210 that can be driven to rotate. A plurality of sample seats 300 are rotatably and linearly disposed in the conveying track 100. When the sample seats 300 are conveyed, they can contact the stop member 210 and be driven by the stop member 210 to separate two adjacent sample seats 300.

[0084] In the above embodiment, the stop 210 provided on the outside of the conveying track 100 limits and blocks the sample holder 300 so that two adjacent sample holders 300 are separated, thereby separating two adjacent sample tubes from each other, so that there is a sufficient gap between the adjacent sample tubes, which facilitates the gripping device to grip the sample tubes for subsequent operations.

[0085] Specifically, such as Figure 1 As shown, the conveying track 100 is generally configured as a circular track, and the sample holder 300 is rotatably and linearly positioned within the conveying track 100 through a clearance fit or other means. In this embodiment, the stop member 210 includes at least a portion that engages with the outer periphery of the sample holder 300 and a portion that prevents the sample holder 300 from continuing to move forward.

[0086] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 As shown, the stop member 210 includes a limiting part 211 and a blocking part 212.

[0087] The limiting part 211 is provided with a groove that conforms to the outer periphery of the sample holder 300; the blocking part 212 is provided on the side of the limiting part 211; the sample holder 300, which moves linearly along the conveying track 100, can be limited by the groove of the limiting part 211, and can continue to move linearly after the stop member 210 rotates away from the groove of the limiting part 211. As the stop member 210 rotates, the blocking part 212 can block the next sample holder 300 adjacent to the sample holder 300, so that the two adjacent sample holders 300 are separated.

[0088] In the above embodiment, by providing a limiting part 211 and a blocking part 212 in the stop member 210, the groove of the limiting part 211 is used to limit the sample holder 300, and the blocking part 212 is used to block the next sample holder 300, so that the two adjacent sample holders 300 are separated, thereby facilitating the clamping device to clamp the sample tube.

[0089] Specifically, such as Figure 6 , Figure 7 , Figure 8 As shown, the sample holders 300 tend to come into close contact with each other during transport on the conveyor track 100. When one sample holder 300 approaches the stop member 210, it is engaged by the groove of the stop member 210, thus limiting its movement. At the same time, the stop member 210 is driven to rotate clockwise. As the stop member 210 rotates, the sample holder 300 disengages from the groove of the limiting part 211 and continues to move linearly. As the stop member 210 rotates, the blocking part 212 is inserted between the sample holder 300 and the adjacent next sample holder 300, thereby preventing the next sample holder 300 from continuing to move forward. This causes the two adjacent sample holders 300 to separate, forming a certain distance, so that there is sufficient gap between the adjacent sample tubes.

[0090] In some embodiments, such as Figure 1 As shown, the drive device 200 also includes a power component 220, and a stop component 210 is provided on the output shaft 221 of the power component 220.

[0091] In the above embodiment, the driving device 200 is driven by the power component 220 to ensure that the gear component 210 rotates stably.

[0092] Specifically, such as Figure 1 As shown, the power component 220 is arranged in the vertical direction, and the output shaft 221 is arranged in the vertical direction; the gear component 210 is arranged on the horizontal plane.

[0093] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
