[0002] According to the patent document with the authorization announcement number "CN218727329U" and the invention name "A fully automatic fluorescent immunoassay analyzer", its description states: when working, the electric slide rail is started, and the electric slider slides in the inner wall of the electric slide rail. The sliding of the electric slider can drive the placement rack to move. When the placement rack moves to the outside of the placement slot, the test tube can be placed in the placement rack. When the placement rack is full and needs to be replaced with a new placement rack, the electric slider can be moved to one end of the inner wall of the electric slide rail, and the placement rack can be removed through the installation mechanism. When the test tube is placed, the test tube can be protected by the protective mechanism. Since the placement rack can be outside the placement slot, it is convenient to take and place the test tube. The protective mechanism includes a protective cover hinged to the top of both sides of one end of the analyzer body. The protective cover can isolate the placement slot from the outside world, thereby protecting the test tube. However, the following defects still exist:

[0003] While the protective cover can isolate the placement slot from the outside world, the protective cover cannot be tightly attached to the analyzer body because it is hinged to the analyzer body, so that outside air may still come into contact with the test tubes stored in the analyzer body and adhere to dust, affecting the use of the test tubes. Utility Model Content

A pressing member 608 is installed on the baffle 602.

[0027] The sealing member 607 includes a sealing plate 6071 arranged on the inner side of the internal groove 606, and a connecting plate 6072 is symmetrically installed on the side of the sealing plate 6071 away from the analyzer body 1, and a first spring 6073 is fixedly installed on the side of the connecting plate 6072 close to the baffle 602, and one end of the first spring 6073 is fixedly connected to the baffle 602, and a pressure block 6074 is fixedly installed on the side of the connecting plate 6072 away from the sealing plate 6071.

At the same time, since the baffle 602 and the inner sealing plate 6071 are in contact with the surface of the analyzer body 1, the sealing effect of the placement chamber 2 is improved.

[0028] The pressing member 608 includes a fixed plate 6081 provided on the side of the baffle 602 away from the analyzer body 1, a guide rod 6082 is symmetrically installed between the fixed plate 6081 and the baffle 602, and the connecting plate 6072 is slidably connected to the guide rod 6082.
