[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.
[0031] In one embodiment, Figure 1-3As shown, a swab rod 41 guiding mechanism includes a mounting frame 30 and a positioning assembly, and the positioning assembly is arranged on the mounting frame 30. The positioning assembly includes a positioning plate 10, and one end of the positioning plate 10 is recessed inward to form a positioning groove matching the diameter of the swab rod 41.
[0032] When in use, first move the positioning assembly or the tube body 43 so that the positioning groove is opposite to the tube mouth of the tube body 43. When the mobile device needs to put the swab stick 41 back into the tube body 43, the mobile device first drives the swab stick 41 that has completed the smearing of the glass slide to be aligned. During the alignment of the swab stick 41, the swab stick 41 slides into the positioning groove from the end of the positioning plate 10, and the positioning groove is used to correct the position of the swab stick 41. Then, the positioning plate 10 is removed, and the mobile device continues to move, driving the swab stick 41 to fully extend into the tube body 43, completing the return of the swab stick 41. Under the limiting effect of the positioning groove, the swab stick 41 can be put back into the tube body 43 more smoothly and accurately, reducing biological contamination, ensuring the preservation of samples and subsequent experiments, reducing the breakage of the swab stick 41 and the damage of the sample storage device 40, reducing the failure rate of the entire sample detection system, and improving the efficiency and quality of medical work.
[0033] In one embodiment, Figure 6 As shown, the positioning groove includes a first section 101 and a second section 102, and the first section 101 and the second section 102 are continuously arranged along the depth direction of the positioning groove, and the bottom of the positioning groove is located in the second section 102, that is, when the swab rod 41 slides into the positioning groove from the end of the positioning plate 10, it first passes through the first section 101, then reaches the second section 102, and finally can abut against the bottom of the positioning groove. The first section 101 is trumpet-shaped, and the width of the end of the first section 101 away from the second section 102 is greater than the width of the end close to the second section 102. The wide mouth design of the trumpet shape helps to prevent the swab rod 41 from getting stuck or blocked when entering the positioning groove, ensuring the smooth placement of the swab rod 41; the two sides of the gradually transitioning first section 101 help guide the swab rod 41 into the positioning groove, making the placement process of the swab rod 41 smoother and more stable. The second section 102 is rectangular, and the width of the second section 102 matches the diameter of the swab rod 41 , so that once the swab rod 41 enters the second section 102 , it can be firmly supported, thereby ensuring the accurate positioning and stability of the swab rod 41 .
[0034] In one embodiment, Figure 3-5As shown, the positioning assembly further includes a connecting plate 11 and a connecting plate 2 12, the positioning plate 10 is fixedly connected to the connecting plate 2 12 through the connecting plate 11, the connecting plate 2 12 is arranged on the mounting frame 30, and the extension direction of the connecting plate 11 is perpendicular to the extension direction of the connecting plate 2 12. The positioning plate 10 is not directly connected to the mounting frame 30, but is indirectly connected through the connecting plate 11 and the connecting plate 2 12, so that the mutually perpendicular connecting plate 11 and the connecting plate 2 12 can adjust the position of the positioning plate 10 from two directions, so that it is not completely restricted by the mounting frame 30, reducing the interference between the structures, facilitating the design of the overall structure of the guide mechanism of the swab rod 41, and facilitating the production and manufacturing.
[0035] In one embodiment, the guiding mechanism of the swab rod 41 also includes an avoidance component disposed on the mounting frame 30, and the avoidance component drives the connection positioning component and drives the positioning component to move between the first position and the second position. When the positioning component is located at the first position, the positioning groove can limit the position of the swab rod 41, thereby ensuring the accuracy and stability of the placement of the swab rod 41; when the positioning component is located at the second position, the positioning groove is away from the swab rod 41, and no longer limits the position of the swab rod 41, which can facilitate the entry and exit or movement of the moving device of the swab rod 41, the swab rod 41, and the cover body 42 at the end of the swab rod 41. The avoidance component can accurately control the position of the positioning component by driving the positioning component to move between the first position and the second position, thereby changing the relative position of the positioning groove and the swab rod 41, making the position adjustment of the positioning component more flexible, and can be adjusted at any time according to actual needs to adapt to different operating requirements.
[0036] Specifically, the avoidance assembly includes a shaft 20 fixed on the mounting frame 30, and the end of the connecting plate 12 away from the connecting plate 1 is sleeved on the shaft 20. The connecting plate 12 is rotatably connected to the mounting frame 30 through the shaft 20, so that the positioning assembly can rotate around the shaft 20 and pass through the first position and the second position. The avoidance assembly also includes a spring, one end of the spring is connected to the mounting frame 30, and the other end is connected to the connecting plate 12. When the spring is in a relaxed state, the positioning assembly is in the first position, and when the spring is in a compressed / stretched state, the positioning assembly is in the second position. Therefore, by compressing or stretching the spring, the positioning assembly can be driven to rotate, thereby changing the position of the positioning plate 10, which is convenient and flexible, and improves the overall efficiency and quality of the sample detection system.
[0037] Specifically, the spring may be a tension spring 21 or a compression spring.
[0038] In other embodiments, the end of the spring away from the mounting bracket 30 can also be connected to other structures of the positioning assembly, such as a connecting plate 11, which can also drive the positioning plate 10 to rotate.
[0039] In one embodiment, the positioning plate 10 is parallel to the connecting plate 1 11 , and when the spring is in a compressed / stretched state, the elastic force of the spring drives the connecting plate 2 12 to move, and the movement direction is toward a direction away from the connecting plate 1 11 .
[0040] Specifically, the spring is a tension spring 21. When the tension spring 21 is in a relaxed state, the connecting plate 12 and the positioning plate 10 are arranged horizontally, the tension spring 21 is arranged above the connecting plate 12 and connected to the upper surface of the connecting plate 12, the connecting plate 11 is arranged below the left end of the connecting plate 12, and the shaft 20 is arranged at the right end of the connecting plate 12. After the positioning plate 10 completes the position correction of the swab rod 41, the moving device drives the swab rod 41 to move downward and extend into the tube body 43. During the movement, the cover body 42 / moving device squeezes the upper surface of the connecting plate 12, driving the connecting plate 12 to drive the connecting plate 11 and the positioning plate 10 to rotate counterclockwise around the shaft 20, so as to avoid the positioning assembly interfering with the movement of the swab rod 41 and the cover body 42, until the swab rod 41 is completely extended into the tube body 43 and the cover body 42 covers the tube body 43.
[0041] In other embodiments, the spring may also be a compression spring, which may be disposed below the second connecting plate 12 and connected to the lower surface of the second connecting plate 12, and may also achieve the function of changing the position of the positioning assembly. In other embodiments, the positions and connection relationships of the spring, the shaft 20, the first connecting plate 11, the second connecting plate 12, and the positioning plate 10 may also be specifically set according to actual space and other conditions.
[0042] In one embodiment, the avoidance assembly further includes a torsion spring sleeved on the shaft 20, one end of the torsion spring is fixedly connected to the shaft 20, and the other end is fixedly connected to the second connecting plate 12. When the torsion spring is in a relaxed state, the positioning assembly is in the first position, and when the torsion spring is in a twisted state, the positioning assembly is in the second position. Specifically, a sleeve is provided at the end of the second connecting plate 12, and the sleeve is sleeved on the shaft 20, so that the positioning assembly can rotate around the shaft 20, and the torsion spring can be provided between the shaft 20 and the sleeve, so that the positioning assembly can be driven to return to its original position through its twisting force.
[0043] In other embodiments, the avoidance component may also be configured as other structures.
[0044] In one embodiment, the avoidance assembly further includes a limiter disposed on the mounting frame 30, and the limiter is disposed on the moving path of the positioning assembly, thereby preventing the positioning assembly from excessively rotating around the shaft 20, causing the performance of the spring or torsion spring to deteriorate or even fail, and also preventing excessive rotation of the positioning assembly from interfering with other structures in the sample detection system. Specifically, the limiter may be a first limit screw 22 and a second limit screw 23 fixed to the mounting frame 30. During the rotation of the positioning assembly, the first limit screw 22 and the second limit screw 23 respectively limit the rotation of the connecting plate 2 12 from the lower end and the upper end, thereby preventing excessive rotation of the positioning assembly. In other embodiments, the limiter may also be a limit block, a limit rod, etc. fixed to the mounting frame 30.
[0045] The swab stick 41 guiding mechanism in the above embodiment can be applied to any scenario where a swab stick 41, a smear stick, a medical cotton swab or other structure needs to be calibrated to improve work efficiency.
[0046] In one embodiment, a sample detection system includes the swab rod 41 guiding mechanism in the above embodiment. By providing the swab rod 41 guiding mechanism, the failure rate of the entire sample detection system is reduced, thereby improving the efficiency and quality of medical work.
