[0002] Microbial analysis equipment can realize the amplification, detection and analysis of nucleic acid molecules in biological samples, and can accurately obtain the required target molecule information. It has been widely used in disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research and other fields.

[0003] At present, conventional commercial microbial analysis equipment, such as Roche LC96, basically uses plastic shells to complete the development of nucleic acid amplification equipment in order to reduce transportation weight and development costs.

[0059] Example:

[0060] A device for real-time detection of environmental microorganisms, such as Figure 1 and Figure 4 As shown, it includes a shell 1, a frame 2 and a detection chip, the detection chip is installed in the frame 2, the frame 2 is installed in the shell 1, the shell 1 has a door 3, and a buffer energy absorption unit is arranged between the shell 1 and the frame 2, as shown in FIG. Figure 2 and Figure 3 As shown; the buffer energy absorption unit is an elastic structure, which is wrapped around the frame 2; the elastic structure is in a contracted state; the inner side of the buffer energy absorption unit is connected to the outer wall of the frame 2, and the outer side is connected to the inner wall of the shell 1.

[0063] In this embodiment, when the device is impacted, the frame 2 and the shell 1 will produce relative displacement. The sliding groove and the slider provided at the side buffer unit 4 can enable the frame 2 and the shell 1 to remain connected when the frame 2 and the shell 1 are relatively displaced, so that the elastic force of the elastic part always acts on the shell 1 and the frame 2, thereby reducing the impact on the frame 2.

The horizontal groove is hook-shaped, and its opening is opened in the horizontal direction. The horizontal bar is embedded in the horizontal groove, and the upper pull plate 11 and the frame body 2 move up and down synchronously.

[0065] like Fig.10As shown, the lower buffer unit 8 includes an elastic part and a lower support plate 12; the elastic part is arranged in the vertical direction, and its lower end is fixedly connected to the housing 1, and its upper end is fixedly connected to the lower support plate 12; the lower support plate 12 is arranged in the horizontal direction, and its upper surface is slidably connected to the lower surface of the frame 2, and the elastic part includes a compression spring and a telescopic rod; the two ends of the telescopic rod are respectively fixedly connected to the lower support plate 12 and the frame 2; the compression spring is sleeved on the telescopic rod, and its two ends are respectively abutted against the lower support plate 12 and the frame 2. In this embodiment, in order to facilitate the installation of the frame 2, the lower support plate 12 is a rectangular annular plate structure.

[0066] like Fig.13 As shown, the front side buffer unit 5 includes an elastic part and a front pressure plate 13; the elastic part is arranged in the horizontal direction, and its two ends are fixedly connected to the door 3 and the front pressure plate 13 respectively; the front pressure plate 13 is arranged in the vertical direction; when the door 3 is in the open state, the front pressure plate 13 is separated from the frame 2; when the door 3 is in the closed state, the front pressure plate 13 is in contact with the frame 2 and is slidably connected. The elastic part includes a compression spring and a telescopic rod; the two ends of the telescopic rod are fixedly connected to the front pressure plate 13 and the frame 2 respectively; the compression spring is sleeved on the telescopic rod, and the two ends are respectively in contact with the front pressure plate 13 and the frame 2. In order to avoid placing the detection chip or observing the detection chip, the front side buffer unit 5 is set into two groups, which are arranged in the vertical direction, installed on both sides of the door 3 plate, and in contact with both sides of the front side of the frame 2.

[0067] like Fig.14 As shown, the rear buffer unit 6 includes an elastic part and a rear pressure plate 14; the elastic part is arranged in the horizontal direction, and its two ends are fixedly connected to the back plate of the housing 1 and the rear pressure plate 14 respectively; the rear pressure plate 14 is arranged in the vertical direction, and the rear pressure plate 14 is in contact with and slidably connected to the frame 2.

At the same time, when the buffer unit in contact with the frame 2 moves or vibrates or is impacted, relative movement occurs between the frame 2 and the shell 1, and the contact state between the buffer unit and the frame 2 is converted into a sliding connection state. The rear compression spring will expand and contract, thereby producing a change in elastic force, which will absorb energy and reduce the energy received by the frame 2.
