[0003] However, general bioanalyzers are placed in places that are easily accessible to personnel. When operators are testing and analyzing reagents, if other personnel accidentally bump into the operators or bump into the placement table while walking, it is very easy to cause the horizontal angle of the analyzer to change, thereby causing the reagents placed inside the analyzer to spill, and then causing the required concentration or ratio of the reagents to change, resulting in errors in the test results. At the same time, most test reagents are chemical substances. If they are spilled, they may corrode or damage the circuits, optical elements or other components inside the instrument, affecting the service life of the instrument. Therefore, we need a bioanalyzer with good stability;

[0004] In order to solve the above problems, this application proposes a bioanalyzer with good stability. Utility Model Content

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-3 , a biological analyzer with good stability, including an analyzer main body 1. A placing groove 2 is provided on the outer side wall of the analyzer main body 1. The analyzer main body 1 is rotatably connected with a support rod 3 through the placing groove 2. The support rod 3 is located inside the placing groove 2. The bottom of the support rod 3 is fixedly connected with a contact plate 4. The cross section of the contact plate 4 is arc-shaped, which is convenient for increasing the contact area between the contact plate 4 and the tabletop or the ground when the analyzer main body 1 is tilted, and improving the stability. The bottom of the analyzer main body 1 is fixedly connected with a sleeve 5. The inner side wall of the sleeve 5 is slidably connected with a support foot 6. The top of the support foot 6 is fixedly connected with a return spring 7. The return spring 7 is located inside the sleeve 5. The top of the support foot 6 is fixedly connected with an extrusion block 8. The extrusion block 8 is located at the center of the return spring 7, and the outer side wall of the extrusion block 8 does not fit with the outer side wall of the return spring 7. An extrusion groove 9 is provided inside the analyzer main body 1. One end of the extrusion block 8 away from the support foot 6 is located inside the extrusion groove 9. The inner side wall of the support rod 3 is fixedly connected with an ejection spring 10. One end of the ejection spring 10 away from the support rod 3 is fixedly connected with the inner side wall of the analyzer main body 1. The bottom of the support rod 3 is fixedly connected with an elastic piece 11. When the support rod 3 is located inside the placing groove 2, one end of the elastic piece 11 away from the support rod 3 is located inside the extrusion groove 9;

[0023] When tilting occurs, the return spring 7 provided at the lower end of the analyzer main body 1 with a lower horizontal height is stressed and contracts. At this time, the support foot 6 contracts into the sleeve 5 under the action of the force generated by the tilt, and at the same time drives the extrusion block 8 to contract into the extrusion groove 9. Further, the top of the extrusion block 8 squeezes the bottom of the elastic piece 11, thereby releasing the locking of the elastic piece 11 on the support rod 3. Under the action of the ejection spring 10, one end of the support rod 3 close to the contact plate 4 pops out towards the outside of the analyzer main body 1, and the other end of the support rod 3 is rotatably connected with the analyzer main body 1. Therefore, after the support rod 3 pops out, there is a certain included angle between the support rod 3 and the analyzer main body 1. At this time, the bottom of the contact plate 4 contacts the tabletop or the ground, supports the analyzer main body 1, improves the stability of the analyzer main body 1, and prevents the analyzer main body 1 from tilting.

[0024] Reference Figure 1 and Figure 4 A base 13 is fixedly connected to the inner bottom of the analyzer body 1. The base 13 is located at the center of the inner bottom wall of the analyzer body 1. A slide groove 14 is opened on the top of the base 13. Two slide grooves 14 are provided. The two slide grooves 14 are symmetrically distributed with respect to the central axis plane of the base 13. The base 13 is slidably connected to a sliding frame 15 through the slide groove 14. Two sliding frames 15 are provided. The outer side walls of the two sliding frames 15 are in contact with each other, and the two slide grooves 14 are perpendicular to the directions of the two slide grooves 14 respectively.

[0025] Reference Figure 1 and Figure 4 The outer side walls of the two sliding frames 15 are fixedly connected with a clamping ring 16, and the openings of the two clamping rings 16 face each other. The two clamping rings 16 form a circular ring when combined, which is convenient for supporting the sample container and preventing the sample container from tipping over during use.

[0026] Reference Figure 1 and Figure 4 The outer walls of the two sliding frames 15 are fixedly connected with fixing plates 17, the outer wall of one of the fixing plates 17 is fixedly connected with a tension spring 18, one end of the tension spring 18 away from one of the fixing plates 17 is fixedly connected to the outer wall of the other fixing plate 17, and the outer walls of the two sliding frames 15 are provided with holes, and the tension spring 18 is located in the holes provided in the outer walls of the two sliding frames 15.

[0027] Reference Figure 2 and Figure 3 The inner wall of the support rod 3 is fixedly connected to the limiting column 12, and a slide is arranged inside the analyzer body 1. The entrance of the slide is located inside the placement groove 2, and the inner wall of the slide is matched with the outer wall of the limiting column 12. When the support rod 3 pops out toward the outside of the analyzer body 1, the limiting column 12 limits the pop-up angle of the support rod 3 to avoid that the angle between the support rod 3 and the analyzer body 1 is too large, thereby causing the support rod 3 and the resistance plate 4 to lose the supporting effect.

[0028] Reference Figure 1 The top of the analyzer body 1 is rotatably connected with a cover plate 19. When the staff is not using the equipment, the cover plate 19 is closed with the analyzer body 1 to prevent dust and other impurities from falling into the interior of the analyzer body 1 and reducing the detection efficiency of the equipment.

[0029] Working principle: When the analyzer body is tilted, the reset spring 7 provided at the lower end of the lower horizontal height of the analyzer body 1 is stressed and contracts. At this time, the support feet 6 contract towards the inside of the sleeve 5 under the action of the force generated by the tilt, and at the same time drive the extrusion block 8 to contract towards the inside of the extrusion groove 9. Further, the top of the extrusion block 8 squeezes the bottom of the elastic piece 11. When one end of the elastic piece 11 located inside the extrusion groove 9 is extruded out of the extrusion groove 9, the locking of the elastic piece 11 to the support rod 3 is released. Under the action of the self-elastic force of the ejection spring 10, the end of the support rod 3 close to the contact plate 4 is ejected towards the outside of the analyzer body 1, and the other end of the support rod 3 is rotatably connected to the analyzer body 1. Therefore, after the support rod 3 is ejected, there is a certain angle between the support rod 3 and the analyzer body 1. At this time, the bottom of the contact plate 4 abuts against the tabletop or the ground to support the analyzer body 1, improve the stability of the analyzer body 1, prevent the analyzer body 1 from tilting, and at the same time, under the action of the self-elastic force of the fixing piece 17, the two sliding frames 15 are pulled, so that the outer side walls of the two snap rings 16 are closely attached to the outer side wall of the reagent container to support the reagent container and prevent the reagent from spilling out during tilting.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
