The first small hole and the second small hole that play a role in detection are in an exposed state, which makes it easy for dust to accumulate in the first small hole and the second small hole, and the dust will affect the transmission of the light source and the detection of the detector.

[0005] To this end, the utility model provides an immunochromatographic quantitative detection device. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: an immunochromatographic quantitative detection device, including a detector body 1, the detector body 1 adopts the detection device mentioned in the background technology, and a base plate 11 is arranged at the bottom of the detector body 1, and the base plate 11 plays a role in supporting the detection device.

[0023] The present technical solution also includes a testing table 2, the function of which is to support the entire testing equipment in the prior art. The middle part of the testing table 2 is rotatably connected to a door frame 3. The top of the testing table 2 is provided with shock-absorbing pads 4 located on both sides of the door frame 3. There are two shock-absorbing pads 4, and a base plate 11 is fixedly set on the shock-absorbing pads 4. The shock-absorbing pads 4 and the base plate 11 are bonded and connected. One shock-absorbing pad 4 corresponds to one detector body 1. This arrangement makes it convenient for the two detector bodies 1 to be used in turn.

[0024] The top of the portal frame 3 is rotatably connected to the sealing cover 5. Specifically, the top of the portal frame 3 is rotatably connected to the crossbeam 31, and the crossbeam 31 is welded to the middle of the top of the sealing cover 5. The opening of the sealing cover 5 faces downward, and a synchronous control group 6 is arranged between the detection platform 2 and the sealing cover 5. The synchronous control group 6 has the function of keeping the sealing cover 5 and the detection platform 2 parallel. When the portal frame 3 swings left and right to the extreme position, the sealing cover 5 will cover the two detector bodies 1 in turn.

[0025] The specific structure of the above-mentioned synchronous control group 6 is that it includes a pulley 61 and a synchronous belt 62. A positioning shaft 21 is welded on the top of the inspection platform 2 and is rotatably connected to the bottom of the portal frame 3. The positioning shaft 21 and one end of the beam 31 are both welded with a pulley 61 connected by a synchronous belt 62. Under the restriction of the synchronous belt 62, the pulley 61 connected to the beam 31 will rotate when the portal frame 3 swings, thereby ensuring that the cover 5 and the inspection platform 2 are in a parallel state.

[0026] The sealing cover 5 and the shock-absorbing pad 4 are in a sealed state when in contact. A filter fan 7 is arranged on the top of the sealing cover 5. The function of the filter fan 7 is to provide clean air into the sealing cover 5. An exhaust hole 8 is opened on one side of the sealing cover 5. When the air pressure in the sealing cover 5 increases, it will be discharged through the exhaust hole 8, so that the hot air in the sealing cover 5 is quickly discharged, thereby accelerating the heat dissipation of the entire detection equipment.

[0027] In this embodiment, an annular groove 41 surrounding the outer peripheral wall of the base plate 11 is formed at the bottom of the shock-absorbing pad 4, and a rubber strip 51 which is interference-fitted with the annular groove 41 is bonded to the bottom of the sealing cover 5. The rubber strip 51 is a rectangular closed-loop structure. After the rubber strip 51 is inserted into the annular groove 41, the sealing cover 5 and the shock-absorbing pad 4 are in a sealed state. This arrangement makes the sealing process simpler.

[0028] In this embodiment, the filter fan 7 includes an air duct 71, a fan 72 and a filter plate 73. One end of the air duct 71 is welded to the enclosure 5, the fan 72 is fixedly arranged in the air duct 71, and the filter plate 73 is arranged on the top of the air duct 71. When the fan 72 is started, the external air will pass through the filter plate 73 and then enter the enclosure 5.

[0029] Furthermore, a perforated plate 711 is welded inside the air duct 71 near the top, and the filter plate 73 is snap-connected to the air duct 71 and limited by the perforated plate 711, that is, the filter plate 73 is placed above the perforated plate 711, and when the filter plate 73 needs to be replaced, a tool can be used to pry it out and remove it for replacement.

[0030] In this embodiment, a handlebar 31 is welded to the top of the portal frame 3 , and the handlebar 31 is a component for manually controlling the swing of the portal frame 3 .

[0031] Working principle: Before testing the sample liquid, first manually hold the handle 32 to drive the door frame 3 to swing. Due to the limiting effect of the synchronous belt 62, the crossbeam 31 will rotate to keep the cover 5 in a horizontal state with the test platform 2. When the rubber sleeve 51 is inserted into the annular groove 41, the cover 5 and the shock-absorbing pad 4 are in a sealed contact state. Then, the fan 72 is powered on, and the fan 72 starts. The external air passes through the filter plate 73 and enters the cover 5. The filtered gas impacts the detection equipment on the detector body 1. The dust accumulated in various places on the detection equipment will be impacted and then discharged through the exhaust hole 8 to prevent dust from blocking the detection channel. Then control the cover 5 to open, put the sample liquid, and then close the cover 5. At this time, the equipment on the detection body 1 can be ventilated and cooled to ensure the normal operation of the detection equipment.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
