[0002] The microorganism detector mainly incubates the sample in the sample container by at least one incubation assembly, and detects the microorganism growth in the sample by a detection assembly. The incubation assembly is a drawer type structure installed inside the housing assembly.

In this embodiment, the locking mechanism 30 fixes the first connecting part and the second connecting part to the casing 11 and the drawer body 21 respectively by screws. Correspondingly, the drawer body 21 is fixedly connected to the casing 11 to prevent the incubation component 20 from sliding out abnormally during handling or transportation. The structure is simple and reliable. After unlocking, the corner code can be fixed to other positions of the casing 11 by screws to facilitate the storage of parts, or the corner code can be moved from the original position along the long axis direction of the waist-shaped hole to the storage position and fixed by screws.

Specifically, when the incubation component 20 is in the closed position, in the absence of external force, the torsion spring 334 is in a compressed state to drive the locking mechanism 30 to lock, and the lock hook 331 abuts against the latch under the action of the torsion force, and the lock hook 331 applies continuous pressure to the latch; the direction of the clasp 332 from the locked position to the unlocked position is consistent with the compression direction of the torsion spring 334. When the external force in the direction from the locked position to the unlocked position is greater than the torsion force, the locking mechanism 30 is unlocked, the latch and the lock hook 331 are separated from each other, and the panel 12 can drive the incubation component 20 to move between the open position and the closed position. In this embodiment, the locking mechanism 30 drives the lock hook 331 to repositionably hook the latch through the torsion force of the torsion spring 334, and the structure is reliable and easy to operate.

When the locking mechanism 30 is unlocked, the incubation assembly 20 can move between an open position and a closed position relative to the housing 11; when the locking mechanism 30 is locked, the locking mechanism 30 can prevent the incubation assembly 20 and / or the panel 12 from moving relative to the housing 11 under the action of an external force. In a specific application, as an alternative embodiment, when the locking mechanism 30 is locked, the movement of the incubation assembly 20 relative to the housing 11 is restricted, so that the incubation assembly 20 moves within a range that does not exceed the incubation chamber.

[0079] As an embodiment, the locking mechanism 30 includes a limit member; the limit member is arranged between the casing 11 and the drawer body 21, and when the incubation component 20 is in the closed position, the limit member can switch from an unlocked state to a locked state; in the locked state, the drawer body 21 is abutted against the casing 11 through the limit member, and the limit member can respond to external force to provide a reverse force to the drawer body 21 to prevent the drawer body 21 from moving relative to the casing 11.

[0080] As an embodiment, the locking mechanism 30 includes a limiter; the limiter is disposed between the housing 11 and the panel 12, the panel 12 being fixedly connected to the drawer body 21, and the panel 12 being configured to drive the incubation assembly 20 to move between an open position and a closed position under the action of an external force. When the panel 12 is closed, the incubation assembly 20 is positioned in the closed position. When the incubation assembly 20 is in the closed position, the limiter can switch from an unlocked state to a locked state. In the locked state, the panel 12 abuts against the housing 11 through the limiter, and the limiter can provide a reverse force to the panel 12 in response to an external force, thereby preventing the panel 12 and the drawer body 21 from moving relative to the housing 11.
