DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a floating plate for multi-sample endotoxin detection, comprising a floating plate body 1, mounting holes 2 and a telescopic bracket 4. The surface of the floating plate body 1 is arranged with mounting holes 2, and the mounting holes 2 can be used to fix the ampoule bottle. The bottom center of the floating plate body 1 is connected with a bracket interface 3, and the bracket interface 3 plays a connecting role. The telescopic bracket 4 is embedded in the bottom end of the bracket interface 3. The telescopic bracket 4 and the bracket interface 3 are detachably inserted and connected. The telescopic bracket 4 can be telescoped according to the required length. The end of the telescopic bracket 4 away from the bracket interface 3 is connected with a silicone suction cup 5, and the silicone suction cup 5 plays a fixing role and can be adsorbed on the water bath partition for fixing. The height of the floating plate body 1 in the water bath is adjusted up and down by the telescopic bracket 4, ensuring that the ampoule bottle can be fully immersed in the water bath and the floating plate body 1 does not deviate from the position with the water flow, thereby avoiding the floating plate drifting everywhere due to the influence of the water flow.

[0021] Limiting grooves 6 are provided at the edges of both sides of the upper surface of the floating plate body 1, and the limiting grooves 6 play a limiting role. A plate cover 7 is provided on the top of the floating plate body 1, and the plate cover 7 can prevent small liquid droplets condensed from water vapor on the lower surface of the water bath lid from dripping into the ampoule bottle, thereby causing pollution and affecting the detection results. Connecting blocks 8 are provided at the bottom edges of both sides of the plate cover 7, and the connecting blocks 8 play a connecting role. Two groups of connecting blocks 8 are respectively embedded in the limiting grooves 6. A card slot 9 is provided in the middle of one side of the connecting block 8 away from the center of the plate cover 7. The card slot 9 plays a limiting role and cooperates with the card block 11 to fix the plate cover 7.

[0022] An active cavity 10 is provided on one side of the two groups of limit grooves 6 away from the center of the floating plate body 1. A clamping block 11 is embedded in the movable cavity 10. The clamping block 11 can move in the movable cavity 10. One end of the clamping block 11 is embedded in the clamping groove 9. The clamping block 11 is embedded in the clamping groove 9 to clamp and fix the plate cover 7 and the floating plate body 1. The end of the clamping block 11 close to the clamping groove 9 is set as an inclined surface.

[0023] The end of the card block 11 away from the card slot 9 is connected to a connecting rod 12, and the outer wall of the connecting rod 12 is sleeved with a spring 13. The two ends of the spring 13 are respectively in contact with the inner wall of the active cavity 10 and the card block 11. The end of the connecting rod 12 away from the card block 11 passes through the floating plate body 1 and is connected to a pull block 14. When the plate cover 7 needs to be disassembled, the pull block 14 can be pulled, and the pull block 14 drives the connecting rod 12 to move outward, and the connecting rod 12 pulls the card block 11 out of the card slot 9, thereby canceling the engagement between the card block and the card slot, and lifting The plate cover 7 can be separated. When installing, the connecting block 8 at the bottom of the plate cover 7 is aligned with the limiting groove 6 and inserted. The clamping block 11 is compressed and contracted into the movable cavity 10, and the spring 13 is compressed and contracted. When the clamping groove 9 in the middle of the connecting block 8 moves to one side of the clamping block 11, the rebound force of the spring 13 pushes the clamping block 11 to be embedded in the clamping groove 9, thereby realizing the fixed installation of the plate cover 7, thereby preventing the ampoule bottle in the installation hole 2 from being condensed by the water vapor liquefied on the lower surface of the cover of the water bath pot and dripping.

[0024] The outer walls on both sides of the float body 1 are connected with float handles 15, and the float body 1 can be lifted by the float handles 15 to facilitate the placement and removal of the float body 1. The bottom edge of the float body 1 is connected with an annular float ring 16, which can enhance the buoyancy of the float body 1 and enable the float body 1 to evenly distribute the weight on the water surface, resist lateral tilt, and enhance the stability of the float body 1.

[0025] The float body 1, the float handle 15 and the bracket interface 3 are all made of PVC. The PVC material contains a large number of tiny bubbles inside, which reduces the overall density and thus has a certain buoyancy. The telescopic bracket 4 is made of 304 stainless steel to prevent rust in water, and the silicone suction cup 5 is made of silicone.

[0026] Working principle: When using a floating plate for multi-sample endotoxin detection, first insert the retractable bracket 4 with the silicone suction cup 5 into the bracket interface 3, and then insert the ampoule into the mounting hole 2 on the floating plate body 1 for fixing, hold the floating plate handle 15 to put the floating plate body 1 into the water bath, and adsorb the silicone suction cup 5 on the water bath partition. The height of the floating plate body 1 in the water bath is adjusted up and down by the retractable bracket 4 to ensure that the ampoule can be fully immersed in the water bath and the floating plate does not shift with the water flow. The plate cover 7 can prevent the small liquid droplets condensed from the water vapor on the lower surface of the water bath cover from dripping into the ampoule, thereby causing pollution and affecting the detection results. When the plate cover 7 needs to be removed, the pull block 14 can be pulled, and the pull block 14 drives the connecting rod 12 to move outward, and the connecting rod 12 pulls the card block 11 out of the card slot 9, thereby canceling the engagement between the card block and the card slot, and the plate cover 7 can be separated by lifting. When installing, align the connecting block 8 at the bottom end of the plate cover 7 with the limiting groove 6 and insert it. The card block 11 is compressed and shrinks into the active cavity 10, and the spring 13 is compressed and shrinks. When the card slot 9 in the middle of the connecting block 8 moves to one side of the card block 11, the card block 11 is pushed to be embedded in the card slot 9 by the rebound force of the spring 13, thereby realizing the fixed installation of the plate cover 7, thereby preventing the ampoule bottle in the installation hole 2 from being condensed by the water vapor on the lower surface of the cover of the water bath pot and being liquefied into small droplets. The annular float ring 16 can increase the buoyancy of the floating plate body 1, and at the same time enable the floating plate body 1 to evenly distribute the weight on the water surface, resist lateral tilt, and improve the stability of the floating plate body 1.
