Description

Technical Field

[0001] The utility model relates to the technical field of enzyme markers, in particular to a small-sized enzyme marker capable of automatically entering and exiting a bin. Background Art

[0002] The microplate reader is an enzyme-linked immunosorbent assay (ELISA) instrument, which is a special instrument for ELISA and is also called a microplate detector. The microplate reader is actually a phase-changing photoelectric colorimeter or spectrophotometer. Its basic working principle and main structure are basically the same as those of a photoelectric colorimeter: the light waves emitted by the light source lamp are converted into a monochromatic light through a filter or a monochromator and enter the sample to be tested in the plastic microplate. Part of the monochromatic light is absorbed by the sample, and the other part passes through the sample to irradiate the photodetector. After signal processing, it is sent to the microprocessor for data processing and calculation, and finally the display and printer display the results.

[0003] The existing small-sized microplate reader includes an illumination device, a receiving device and a detection device. The receiving device is provided with an intermediate space, which is an open measurement structure for inserting and placing microplates. The intermediate space of the existing small-sized microplate reader is not provided with an automatic entry and exit structure for microplates, which makes it difficult to put microplates into and out of the intermediate space, affecting the convenience of using the small-sized microplate reader.

The automatic entry and exit structure for microplates comprises a rebound device 5.

[0023] like Figure 4-Figure 5 As shown, the rebounder device includes a rebounder track base 10, a rebounder slider 7, a rebounder ejection device 11 and a rebounder lock tongue 12. The rebounder track base is fixedly mounted on the inner end of the middle space of the detection device, a track is arranged on the rebounder track base, and a rebounder slider is connected to the track and slides forward and backward along the track. The rebounder slider is provided with a slider upper end surface 8 and a slider lower end surface 9 that protrude forward in a stepped manner, a rebounder ejection device is installed between the slider lower end surface and the rebounder track base, a notch is provided on the stepped surface between the slider upper end surface and the slider lower end surface, a lock hole is provided on the rebounder ejection device, a rebounder lock tongue is installed in the lock hole, and a travel switch is installed at the extreme position of the rebounder ejection device, and the travel switch controls the pop-up and retraction of the rebounder lock tongue.

[0024] like Figure 6-Figure 7 As shown, the automatic entry and exit structure of the microplate also includes a propulsion device 6, which includes a propulsion device slider 13, a propulsion device slide rail 14 and a propulsion device spring 15. The propulsion device slider is connected to the propulsion device slide rail and slides back and forth along the propulsion device slide rail. The propulsion device spring is installed on the propulsion device slide rail. The propulsion device spring presses the propulsion device slider to keep the propulsion device slider located at the outer end of the propulsion device slide rail.

[0025] The propulsion device is symmetrically mounted on the detection device at two sides of the middle space. The rebounder device is mounted on the detection device at the center of the inner side end of the middle space.
