[0016] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0017] See also Figure 1 and Figure 2 , the utility model provides a technical solution:

[0018] A detection device for opening and closing the door of an automatic sampler is installed on a box (not shown in the figure). The box contains an instrument (not shown in the figure) and a main controller (not shown in the figure) that are electrically connected to each other. The box is provided with an observation window (not shown in the figure). The detection device includes a frame structure installed at the observation window and a detection unit installed on the frame structure. The frame structure covers the observation window. The detection unit is electrically connected to the main controller.

[0019] In this embodiment, the frame structure includes a frame 101 mounted at the observation window and a cover 102. A transparent plate 103 is mounted within the frame 101, covering the observation window. The left end of the frame 101 and the left end of the cover 102 are hingedly connected. The right end of the frame 101 and the right end of the cover 102 are detachably connected via a male-female buckle 104, allowing the cover 102 to be snapped onto the frame 101. In this embodiment, the male buckle of the male-female buckle 104 is mounted on the cover 102, while the female buckle of the male-female buckle 104 is mounted on the frame 101.

[0020] Specifically, in this embodiment, the detection unit includes a microswitch 201 and a light strip 202. The microswitch 201 is mounted on the side wall of the cover 102 near the frame 101, allowing it to abut the frame 101. The light strip 202 is mounted within the cover 102. Both the microswitch 201 and the light strip 202 are electrically connected to the main controller. The microswitch 201 has a small contact spacing and a snap-action mechanism, which switches with a specified stroke and force. It is covered by a housing and has an external drive rod. External mechanical force acts on the actuating reed through a transmission element, causing the fixed contact at its end to quickly connect or disconnect with the moving contact. The microswitch 201 used in this embodiment is model: CHINT Microswitch 201 Limit Switch Small Travel Switch YBLXW-6 / 11CL.

[0021] The status of the instrument inside the box can be judged by the different colors displayed by the light strip 202:

[0022] 1. When the cover 102 is opened, the male buckle and the female buckle of the male and female buckle 104 are separated, and the micro switch 201 pops outward. At this time, the light strip 202 displays white.

[0023] 2. When the cover 102 is closed, the male buckle and the female buckle of the male and female buckle 104 are tightly fastened, and at the same time, the micro switch 201 is compressed inward, and the light strip 202 displays blue.

[0024] 3. When the light strip 202 displays red, it means that the instrument in the box is operating abnormally and is in an alarm state.

[0025] 4. When the instrument in the box is operating normally, the light strip 202 is always in a constantly on state, making it convenient for outsiders to observe the internal operating status of the instrument through the transparent plate 103.

[0026] In order to facilitate opening the cover 102 , a groove 301 is specially designed at the right end of the cover 102 in this embodiment to facilitate the application of fingers when opening the cover 102 .

[0027] In order to facilitate the passage of liquid pipelines, realize the connection between internal and external instruments, and achieve the function of multi-instrument collaboration, a through hole is specially opened at the right end of the cover body 102, so that the liquid pipelines of the instruments outside the box can pass through this through hole and enter the box. To protect the liquid pipelines, a coil 401 is installed in the through hole.

[0028] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
