Description

Technical Field

[0001] This utility model belongs to the field of sample tube stabilization technology for cell detectors, specifically relating to a sample tube positioning and stabilization structure. Background Technology

[0002] Cell detectors are devices used for high-precision and high-efficiency detection and analysis of cell samples. They are widely used in biomedical research, clinical diagnosis, and biotechnology. Chinese utility model patent CN220603487U discloses a cell detector, which includes a detection module, a rotary sample loading module, and a pipetting module. The detection module includes multiple cell detectors, each with a sample loading port for adding samples. The rotary sample loading module includes a turntable, a first rotary motor, and multiple sample containers mounted on the turntable. The turntable is connected to the first rotary motor, which drives the turntable to rotate, moving the sample containers to the manual sample loading position and the automatic sampling position. The pipetting module includes a transfer assembly and a pipette mounted on the transfer assembly. The pipette can move to the automatic sampling position and the sample loading port of the cell detector under the drive of the transfer assembly. The cell detector provided by this invention, by adopting a design that combines multiple detectors with a rotating sample loading module working in parallel, achieves high-speed, high-precision, and highly automated detection and analysis of multiple cell samples, thereby solving the efficiency bottleneck problem of traditional single detector designs.

[0003] The application discloses a rotary sample loading module consisting of a turntable, a first rotary motor, a sample container, a clamping component, a clamping port, a sensor, a cover, and a sample loading port. The rotary sample loading module is used to rotate and load multiple sample tubes, thereby enabling highly efficient automated detection and analysis of multiple cell samples.

[0004] However, as can be seen from the specification and accompanying drawings, the rotary sample loading module in this application mainly clamps and limits the sample tubes by engaging clamping components. Furthermore, the operator needs to manually place the sample tubes into the clamping components during clamping. While this method can clamp and fix the sample tubes, the stability of clamping the sample tubes in practical applications is poor. This can easily lead to inconsistent clamping heights among multiple sample tubes and wobbling during the rotary loading process, resulting in poor reliability of sample tube clamping and loading.

[0005] Therefore, to address the aforementioned technical issues, it is necessary to provide a stable structure for the sample tube in place.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a stable structure for the positioning of sample tubes, which can improve the stability of clamping and loading sample tubes.

[0008] To achieve the above objectives, a specific embodiment of this utility model provides a sample tube positioning and stabilization structure, including: a worktable, a rotary feeding assembly, and multiple sets of auxiliary clamping assemblies.

[0009] The rotary feeding assembly is mounted above the worktable. The rotary feeding assembly includes a turntable, which is mounted above the worktable. A supporting shaft is fixedly connected to the bottom of the turntable, and the supporting shaft is rotatably connected to the worktable.

[0010] Multiple sets of the auxiliary clamping components are evenly distributed on the outer side of the turntable. Each auxiliary clamping component includes a clamping block, which is fixedly assembled on the outer side of the turntable. A pair of arc-shaped engaging parts are fixedly connected to the side of the clamping block away from the turntable. The pair of arc-shaped engaging parts cooperate with the clamping block to form an engaging cavity. A pair of friction pads are fixedly connected to the inner wall of the engaging cavity. A limiting pressure plate is slidably assembled above the clamping block, and the limiting pressure plate is correspondingly arranged with the engaging cavity.

[0011] In one or more embodiments of this utility model, a cover is fitted over the outer side of the turntable, and the cover is fixedly mounted above the worktable. The cover protects the turntable, reducing the risk of contamination of the sample tubes due to environmental factors during the rotating loading process. A sample loading port is provided on one side of the cover. Sample tubes are manually loaded through the sample loading port.

[0012] In one or more embodiments of this utility model, a transmission box is fixedly connected below the worktable. The transmission box provides assembly and operating space for the drive shaft, drive bevel gear, and transmission bevel gear. The support shaft is integrally formed with the drive shaft at one end located inside the transmission box. The support shaft is rotated by driving the drive shaft to rotate, thereby facilitating the rotation of the turntable to feed the sample tube.

[0013] In one or more embodiments of this utility model, a drive bevel gear is fixedly connected to the outer side of the drive shaft. The drive bevel gear drives the drive shaft to rotate. A transmission bevel gear meshes with one side of the drive bevel gear. The transmission bevel gear transmits power from the rotary motor, and the drive shaft rotates synchronously with the output shaft of the rotary motor under the meshing action of the drive bevel gear and the transmission bevel gear. A rotary motor is fixedly mounted on one side of the transmission box, and the output shaft of the rotary motor is connected to the transmission bevel gear. The rotary motor provides power, and the drive shaft is driven to rotate by controlling the operation of the rotary motor.

[0014] In one or more embodiments of this utility model, a pair of assembly plates are integrally formed on the side of the clamping block closest to the worktable, and the spacing between the pair of assembly plates is consistent with the thickness of the turntable. Multiple sets of auxiliary clamping components are assembled onto the outer side of the turntable through the mutual cooperation of the pair of assembly plates and the turntable. Assembly bolts are fixedly connected between the pair of assembly plates and the turntable. The assembly bolts serve to assemble and fix the assembly plates to the turntable.

[0015] In one or more embodiments of this utility model, a pair of friction pads are symmetrically arranged on both sides of the locking cavity. This facilitates the auxiliary clamping of the sample tube using the pair of friction pads. The sides of the pair of friction pads that are in contact with each other are integrally formed with multiple evenly distributed anti-slip protrusions. By providing multiple evenly distributed anti-slip protrusions on the inner surface of the friction pads, the friction between the friction pads and the outer surface of the sample tube is increased, thereby improving the stability of the friction pads in assisting in clamping the sample tube.

[0016] In one or more embodiments of this utility model, a pair of compression cylinders are fixedly assembled inside the clamping block. The compression cylinders serve to slide and limit the piston block. Simultaneously, the compression cylinders function as gas storage. A piston block is slidably assembled inside each pair of compression cylinders. The movement of the piston blocks controls the compression of the gas storage chamber, thereby facilitating the control of the gas delivery and retraction within the chamber. The lower end face of the piston block mates with the compression cylinder to form the gas storage chamber. The delivery and retraction of the gas within the friction pad are controlled by adjusting the volume of the gas storage chamber.

[0017] In one or more embodiments of this utility model, a connecting pipe is provided between the pair of compression cylinders, and both ends of the connecting pipe are connected to the compression storage chamber. The connecting pipe serves as a connecting pipe between the pair of compression storage chambers. A support rod is fixedly connected to the side of the piston block away from the compression storage chamber. The support rod provides support and movement control for the piston block.

[0018] In one or more embodiments of this utility model, a linkage plate is fixedly connected to one end of the support rod located outside the compression cylinder. The linkage plate connects and fixes the limiting pressure plate and the support rod, allowing the support rod to move synchronously with the movement of the limiting pressure plate. A connecting spring is provided between the linkage plate and the compression cylinder, and the connecting spring is fitted onto the outside of the support rod. The contraction and return of the connecting spring provides support and limitation for the linkage plate.

[0019] In one or more embodiments of this utility model, a guide air pipe is connected between each pair of compression cylinders and the friction inner pad. One end of the guide air pipe is connected to the compression storage chamber, and the other end of the guide air pipe is connected to the friction inner pad. The guide air pipe serves to connect the compression storage chamber and the friction inner pad, facilitating the flow of gas between the compression storage chamber and the friction inner pad under the action of the guide air pipe.

[0020] Compared with the prior art, the sample tube positioning and stabilizing structure disclosed in this utility model can assist in clamping and fixing the sample tube through the setting of the corresponding structure, reducing the situation of multiple sample tubes having different heights during the clamping process, and improving the reliability and stability of clamping and feeding the sample tubes.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figures 1 to 8 As shown, the sample tube positioning and stabilization structure in one embodiment of this utility model includes: a worktable 1, a rotary feeding assembly 2, and multiple sets of auxiliary clamping assemblies 3.

[0034] like Figure 1 As shown, the rotary feeding assembly 2 is mounted above the worktable 1. The rotary feeding assembly 2 includes a turntable 201, which is mounted above the worktable 1. The turntable 201 is used to assemble, fix, and rotate multiple sets of auxiliary clamping assemblies 3, thereby facilitating the rotary feeding of multiple sample tubes.

[0035] like Figure 7 As shown, a supporting shaft 202 is fixedly connected to the lower part of the turntable 201, and the supporting shaft 202 is rotatably connected to the worktable 1. The supporting shaft 202 serves to support, limit, and drive the rotation of the turntable 201.

[0036] like Figure 8 As shown, a cover 203 is fitted over the outer side of the turntable 201, and the cover 203 is fixedly mounted on top of the worktable 1. The cover 203 protects the turntable 201, reducing the risk of contamination of the sample tubes due to environmental factors during the rotating feeding process.

[0037] Specifically, a sample loading port is provided on one side of the cover 203. The sample tube is manually loaded through the sample loading port.

[0038] like Figures 7 to 8 As shown, a transmission box 204 is fixedly connected to the lower part of the worktable 1. The transmission box 204 provides assembly and operating space for the drive shaft 205, drive bevel gear 206, and transmission bevel gear 207.

[0039] like Figures 7 to 8 As shown, the supporting shaft 202 is integrated with a drive shaft 205 at one end inside the transmission box 204. The supporting shaft 202 is rotated by driving the drive shaft 205 to rotate, thereby facilitating the rotation of the drive turntable 201 to feed the sample tube.

[0040] like Figures 7 to 8 As shown, a drive bevel gear 206 is fixedly connected to the outer side of the drive shaft 205. The drive bevel gear 206 drives the drive shaft 205 to rotate.

[0041] like Figures 7 to 8 As shown, a transmission bevel gear 207 meshes with one side of the drive bevel gear 206. The transmission bevel gear 207 transmits power to the rotary motor 208, and the drive shaft 205 rotates synchronously with the output shaft of the rotary motor 208 under the meshing action of the drive bevel gear 206 and the transmission bevel gear 207.

[0042] like Figures 7 to 8 As shown, a rotary motor 208 is fixedly mounted on one side of the transmission box 204, and the output shaft of the rotary motor 208 is connected to the transmission bevel gear 207. The rotary motor 208 provides power, and the operation of the rotary motor 208 is controlled to drive the drive shaft 205 to rotate.

[0043] like Figures 2 to 4 As shown, multiple sets of auxiliary clamping components 3 are evenly distributed on the outer side of the turntable 201. Each auxiliary clamping component 3 includes a clamping block 301, which is fixedly assembled on the outer side of the turntable 201. The clamping block 301 serves to assemble and fix a pair of arc-shaped engaging parts 302 and a pair of assembly plates 306. At the same time, the clamping block 301 provides auxiliary clamping and limiting for the sample tube to be clamped.

[0044] like Figures 2 to 3 As shown, a pair of mounting plates 306 are integrally formed on the side of the clamping block 301 close to the worktable 1, and the spacing between the pair of mounting plates 306 is the same as the thickness of the turntable 201. Through the mutual cooperation between the pair of mounting plates 306 and the turntable 201, multiple sets of auxiliary clamping components 3 are assembled on the outside of the turntable 201.

[0045] like Figures 2 to 3 As shown, a pair of assembly plates 306 are fixedly connected to the turntable 201 by assembly bolts 307. The assembly bolts 307 serve to assemble and fix the assembly plates 306 and the turntable 201.

[0046] like Figures 2 to 3 As shown, a pair of arc-shaped locking parts 302 are fixedly connected to the side of the clamping block 301 opposite to the turntable 201. The sample tube is assembled by the mutual cooperation between the pair of arc-shaped locking parts 302 and the clamping block 301.

[0047] Specifically, a pair of arc-shaped locking elements 302 cooperate with the clamping block 301 to form a locking cavity 303. The locking cavity 303 can support and limit the position of the sample tube.

[0048] like Figures 2 to 4 As shown, a pair of friction pads 304 are fixedly connected to the inner wall of the locking cavity 303. The pair of friction pads 304 assist in clamping and limiting the sample tube, ensuring the stability of clamping and fixing the sample tube.

[0049] Specifically, a pair of friction pads 304 are symmetrically arranged on both sides of the engagement cavity 303. This facilitates the auxiliary clamping of the sample tube using the pair of friction pads 304.

[0050] like Figures 2 to 4 As shown, a pair of friction pads 304 have multiple evenly distributed anti-slip protrusions 308 integrally formed on the side of their contact surfaces. By setting multiple evenly distributed anti-slip protrusions 308 on the inner surface of the friction pads 304, the friction between the friction pads 304 and the outer surface of the sample tube is increased, thereby improving the stability of the friction pads 304 in assisting to hold the sample tube.

[0051] like Figures 2 to 4 As shown, a limiting pressure plate 305 is slidably mounted above the clamping block 301, and the limiting pressure plate 305 is correspondingly set with the locking cavity 303. The limiting pressure plate 305 presses and limits the top of the sample tube, reducing the possibility of multiple sample tubes having different heights during clamping.

[0052] like Figures 5 to 6 As shown, a pair of compression cylinders 309 are fixedly assembled inside the clamping block 301. The compression cylinders 309 serve as sliding limiters for the piston block 310. At the same time, the compression cylinders 309 serve as gas storage.

[0053] like Figure 5 As shown, piston blocks 310 are slidably mounted inside each of the pair of compression cylinders 309. The movement of the piston blocks 310 controls the compression of the compression storage chamber 311, thereby facilitating the control of the gas delivery and retraction state within the compression storage chamber 311.

[0054] like Figure 5As shown, the lower end face of the piston block 310 mates with the compression cylinder 309 to form a compression storage chamber 311. The delivery and retraction of gas within the friction pad 304 are controlled by adjusting the volume of the compression storage chamber 311.

[0055] like Figures 5 to 6 As shown, a connecting pipe 312 connects a pair of compression cylinders 309, with both ends of the connecting pipe 312 communicating with the compression storage chamber 311. The connecting pipe 312 serves as a connecting pipe between the pair of compression storage chambers 311. A support rod 313 is fixedly connected to the side of the piston block 310 away from the compression storage chamber 311. The support rod 313 provides support and movement control for the piston block 310.

[0056] like Figures 2 to 5 As shown, a linkage plate 314 is fixedly connected to one end of the support rod 313 outside the compression cylinder 309. The linkage plate 314 connects and fixes the limiting pressure plate 305 and the support rod 313, so that the support rod 313 can move synchronously with the movement of the limiting pressure plate 305.

[0057] like Figures 3 to 4 As shown, a connecting spring 315 is arranged between the linkage plate 314 and the compression cylinder 309, and the connecting spring 315 is sleeved on the outside of the support rod 313. The contraction and reset of the connecting spring 315 provides support and limit for the linkage plate 314.

[0058] like Figure 6 As shown, a guide air pipe 316 connects each of the pair of compression cylinders 309 and the friction inner pad 304. One end of the guide air pipe 316 is connected to the compression storage chamber 311, and the other end is connected to the friction inner pad 304. The guide air pipe 316 serves to connect the compression storage chamber 311 and the friction inner pad 304, facilitating the flow of gas within both chambers under the influence of the guide air pipe 316.

[0059] In practical use, the operation of the rotary motor 208 can drive the transmission bevel gear 207 to rotate. The drive shaft 205 drives the turntable 201 to rotate under the meshing action of the drive bevel gear 206 and the transmission bevel gear 207. When the turntable 201 rotates to the sample port position of the cover 203, the limiting pressure plate 305 can be manually pulled up and the sample tube can be pushed into the locking cavity 303. The sample tube is initially limited by the locking of the clamping block 301 and a pair of arc-shaped locking parts 302.

[0060] When the limiting pressure plate 305 is pulled up, the volume of the compressed gas storage chamber 311 increases, which allows the gas in the pair of friction pads 304 to be transported to the compression cylinder 309 under the action of gas pressure along the guide gas tube 316. The friction pads 304 can also shrink, which simplifies the process of pushing and locking the sample tube.

[0061] Subsequently, the limiting pressure plate 305 can be lowered, and the linkage plate 314 drives the support rod 313 to descend under the action of the connecting spring 315. The top of the sample tube is pressed and limited by the descent of the limiting pressure plate 305, thereby reducing the situation of inconsistent heights of multiple sample tubes during clamping. During the reset process of the limiting pressure plate 305, the volume of the compressed gas storage chamber 311 decreases, and the gas in the compressed gas storage chamber 311 is transported to the friction inner pad 304 along the guide gas pipe 316. The expansion of the friction inner pad 304 allows the friction inner pad 304 to assist in clamping the sample tube, ensuring the stability of clamping and limiting the sample tube.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
