Description

Technical Field

[0001] This utility model belongs to the field of detection instruments, and in particular relates to a biological detection instrument. Background Technology

[0002] In recent years, molecular-level detection of pathogenic bacteria in food has become rapidly widespread. The detection process mainly includes three steps: pretreatment, nucleic acid extraction, and nucleic acid amplification and detection. In the pretreatment process, the sample is mechanically pulverized and then cultured in an incubator.

[0003] A search revealed an existing technology (publication number: CN222540743U) for a rapid biological detection instrument. The paper proposes that "a detection box can be installed inside the housing, allowing for modular assembly. A support spring is used to install a fixing block, which, combined with a protective plate on the surface, provides elastic support after covering and protection, facilitating vibration operation, making it convenient and efficient, and beneficial for vibration culture for detection." However, in actual use, this device cannot effectively secure reagent bottles of different sizes, nor is it convenient to observe the shaking and fusion process of the test substance inside the bottle, resulting in significant operational inconvenience. Therefore, designing a biological detection instrument is essential. Utility Model Content

[0021] Example 1

[0022] like Figures 1 to 4As shown, a biological detector according to the first aspect of this utility model includes: a base plate 1; a protective shell 4 fixedly connected to the top surface of the base plate 1, a sealing cover 6 placed on the top surface of the protective shell 4, a handle 7 fixedly connected to the top surface of the sealing cover 6, an observation window 5 provided on one side of the protective shell 4, and multiple fixed cylinders 10 provided inside the protective shell 4. A spring 11 is fixedly connected to the bottom surface of the inner wall of each fixed cylinder 10, and a sliding rod 12 is fixedly connected to the top of each spring 11. The rod wall of each sliding rod 12 is connected to the corresponding fixed cylinder 10. The inner wall is slidably connected, and the top surfaces of multiple sliding rods 12 are fixedly connected to a bracket 13. The top surface of the bracket 13 is equipped with a vibration motor 9, and the top surface of the bracket 13 has multiple placement holes 14. The bottom surface of each base plate 1 is fixedly connected with four support legs 8. A control component 2 is assembled inside the base plate 1. The control component 2 is used to control the rotation of the bracket 13 to cooperate with the observation window 5 for observing the reagent. Multiple fixing components 3 are assembled inside the bracket 13. Each fixing component 3 is used to fix the reagent bottle inside the corresponding placement hole 14.

[0023] The technical effects achieved by the above embodiments are as follows: By setting a support structure consisting of a fixed cylinder 10, a spring 11, and a sliding rod 12 inside the protective shell 4 to support the bracket 13, during operation, the vibration motor 9 drives the bracket 13 to shake, thereby allowing the test items in the reagent bottles placed on it to shake and fuse. At the same time, the control component 2 drives the bracket 13 to rotate, which cooperates with the observation window 5 on the surface of the protective shell 4, allowing the operator to clearly observe the fusion effect in each reagent bottle. The fixed component 3 can effectively fix the reagent bottles in the placement hole 14, preventing them from falling or colliding during shaking, thereby significantly improving the reliability and effectiveness of the device.

[0024] Example 2

[0025] like Figure 1 and Figure 2As shown, a biological detector includes all the contents of Embodiment 1. Furthermore, the control component 2 includes: a mounting cavity 201 formed in the inner wall of the base plate 1; a control groove 202 formed on one side of the inner wall of the mounting cavity 201; the control groove 202 communicating with the surface of the base plate 1; and the control component 2 further includes: a gear 204 rotatably connected to the bottom surface of the inner wall of the mounting cavity 201; one side of the gear 204 meshes with a gear 203; and one side of the gear 203 extends to the base plate through the control groove 202. On the surface of 1, the control component 2 further includes: a transmission rod 208 fixedly connected to the top surface of gear 204, the top end of the transmission rod 208 extending to the top surface of the base plate 1 and fixedly connected to a fixing plate 207, the top surface of the fixing plate 207 being fixedly connected to the bottom end of each fixing cylinder 10 respectively, and the control component 2 further includes: an annular groove 206 formed on the top surface of the base plate 1, the inner wall of the annular groove 206 being slidably connected to a limiting ring 205, the top surface of the limiting ring 205 being fixedly connected to the bottom surface of the fixing plate 207.

[0026] The technical effects achieved by the above embodiments are as follows: Through the installation cavity 201 and control groove 202 inside the base plate 1, the gear 203 extends to the surface for easy manual operation and meshes with the gear 1 204 to drive the transmission rod 208 fixedly connected to the top surface of the gear 1 204 to rotate, thereby driving the fixed plate 207 to rotate; the fixed plate 207 is connected to the bottom end of the fixed cylinder 10, so that the bracket 13 rotates smoothly as a whole. At the same time, the annular groove 206 cooperates with the limiting ring 205 to limit the rotation and ensure that there is no deviation. This transmission mechanism allows the reagent bottles in the placement hole 14 on the bracket 13 to be aligned with the observation window 5 on the surface of the protective shell 4 in sequence. Combined with the vibration motor 9 driving the bracket 13 to shake through the support structure composed of the fixed cylinder 10, spring 11 and slide rod 12, it promotes the shaking and fusion of the test objects. The fixing component 3 fixes the reagent bottles from the inside to prevent them from falling, thereby realizing clear observation of the fusion process of each reagent bottle and improving the ease of operation and reliability of the device.

[0027] Example 3

[0028] like Figure 1 and Figure 4 As shown, a biological detector includes all the contents of Embodiment 2. In addition, the fixing component 3 includes: two fixing cavities 302 formed in the inner wall of the support 13, a spring 303 fixedly connected to one side of the inner wall of each fixing cavity 302, a mounting block 304 fixedly connected to one end of each spring 303, the surface of each mounting block 304 being slidably connected to the inner wall of the corresponding fixing cavity 302, a fixing block 301 fixedly connected to one side of each mounting block 304, and one side of each fixing block 301 extending into the interior of the corresponding placement hole 14.

[0029] The technical effects achieved by the above embodiments are as follows: Through the two fixed cavities 302, spring 2 303 and mounting block 304 symmetrically arranged inside the bracket 13, the fixed block 301 is driven to move towards the center of the placement hole 14. When the vibration motor 9 drives the bracket 13 to shake through the support structure composed of the fixed cylinder 10, spring 11 and slide rod 12, the fixed block 301 made of elastic rubber material can adapt to the bottle body of different specifications of reagent bottles and provide continuous elastic clamping force, effectively preventing the reagent bottles from tilting, colliding or slipping during the shaking and mixing process. At the same time, combined with the control component 2, the bracket 13 is rotated as a whole through gear 1 204, gear 2 203, transmission rod 208 and fixing plate 207, so that each reagent bottle that is firmly fixed can be aligned with the observation window 5 on the surface of the protective shell 4 in turn, which facilitates clear observation of the mixing state of the test substance in the bottle from multiple angles. Thus, while ensuring the vibration mixing effect, the stability of operation and the convenience of observation are significantly improved.

[0030] Example 4

[0031] like Figure 1 and Figure 3 As shown, a biological detector includes all the contents of Example 3. In addition, two connecting blocks 15 are fixedly connected to the surface of the protective shell 4. A connecting rod 16 is hinged to the inner wall of each connecting block 15. A fixing screw 17 is threaded to the inner wall of each connecting rod 16. An abutment block 18 is fixedly connected to the bottom end of each fixing screw 17.

[0032] The technical effect achieved by the above embodiment is as follows: by rotating the two connecting rods 16 to make the two fixing screws 17 located on the top surface of the sealing cover 6, rotating each fixing screw 17 can cause the corresponding abutment block 18 to move downward to abut against the sealing cover 6, thereby completing the fixing of the sealing cover 6.
