[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: A laboratory reagent cabinet that is opened using a barcode scanner, such as... Figs. 1-4 As shown, the reagent cabinet includes a reagent cabinet 1. Several storage slots 12 are evenly distributed on one side of the reagent cabinet 1. A cabinet door 2 is rotatably connected inside the storage slot 12. A damping rod 3 is rotatably connected to the side of the cabinet door 2 near the storage slot 12. The end of the damping rod 3 away from the cabinet door 2 is rotatably connected to the inner wall of the storage slot 12. A spring 11 is provided on the outside of the damping rod 3, and the damping rod 3 is inserted into the spring 11.

[0026] Before the cabinet door 2 is opened by scanning the code, the damping rod 3 and the spring 11 are in the original state of no stretching. When the cabinet door 2 is automatically popped out by scanning the code, the damping rod 3 and the spring 11 are stretched at the same time. When the test personnel take out the reagent, the spring 11 drives the damping rod 3 to return to the original position under the rebounding action. When the damping rod 3 is in the original state, the cabinet door 2 is in the closed state. The spring 11 and the damping rod 3 are used to limit the cabinet door 2. First, when the cabinet door 2 is opened, the cabinet door 2 can be prevented from being instantly popped open to cause the impact injury to the test personnel under the damping action of the damping rod 3 and the rebounding action of the spring 11. Second, when the reagent is placed in the storage groove 12, the cabinet door 2 is tightly attached to the cabinet door 2 due to the external force, so that the cabinet door 2 is instantly opened to cause the reagent to fall. Third, when the cabinet door 2 is opened, the test personnel will not be convenient to close the door with the reagent in hand, and will forget to close the cabinet door 2. At this time, the cabinet door 2 can be automatically closed under the rebounding action of the spring 11, and the closing speed of the cabinet door 2 under the pulling of the spring 11 can be slowed down under the damping action of the damping rod 3, so as to provide sufficient time for the test personnel to take the reagent.

[0027] As shown in Figs. 1-4 , the damping rod 3 is composed of a piston rod 301 and a piston cylinder 302, and the piston rod 301 slides in the piston cylinder 302.

[0028] The side of the piston rod 301 away from the piston cylinder 302 and the side of the piston cylinder 302 away from the piston rod 301 are both provided with a rotating column 6, and the rotating column 6 is rotatably connected with a rotating support column 5.

[0029] The rotating support column 5 is provided with a rotating connecting block 4 on opposite sides, and the two rotating connecting blocks 4 are fixedly connected with the cabinet door 2 and the inner wall of the storage groove 12 respectively.

[0030] When the damping rod 3 is stretched, the piston rod 301 moves in the piston cylinder 302, and under the action of the piston rod 301 and the piston cylinder 302, the opening and closing of the cabinet door 2 is limited. The rotating column 6, the rotating support column 5 and the rotating connecting block 4 can ensure that the damping rod 3 can rotate when the cabinet door 2 is opened and closed, prevent the cabinet door 2 from being stuck due to the angle problem of the damping rod 3, and ensure the stability of the running angle of the damping rod 3.

[0031] As shown in Figs. 1-4 , one end of the piston rod 301 is inserted with an extension cylinder 7, one end of the piston cylinder 302 is inserted with a storage cylinder 8, and the extension cylinder 7 slides in the storage cylinder 8.

[0032] The spring 11 is located in the extension cylinder 7 and the storage cylinder 8, and the opposite ends of the spring 11 are fixedly connected with the inner walls of the two ends of the extension cylinder 7 and the storage cylinder 8 respectively.

[0033] When the piston rod 301 is stretched, the extension cylinder 7 is driven to move at the same time, and the spring 11 is stretched. Under the action of the extension cylinder 7 and the storage cylinder 8, the first pair of springs 11 plays a supporting role, so that the spring 11 is always in a fixed position, ensuring the stability of the spring 11 operation. Secondly, under the connection of the extension cylinder 7 and the storage cylinder 8, the spring 11 can be stretched at the same time as the piston rod 301, further ensuring the stability of the device operation. Thirdly, the extension cylinder 7 and the storage cylinder 8 play a protective role on the spring 11, preventing the spring 11 from being eroded by being in the storage groove 12 filled with chemical reagents for a long time, and prolonging the service life of the spring 11.

[0034] As shown in Figs. 1-4 The outer surface of the extension cylinder 7 is symmetrically provided with two sliding blocks 9, and the inner walls of the opposite sides of the storage cylinder 8 close to the sliding blocks 9 are provided with sliding grooves 10, and the sliding blocks 9 slide in the sliding grooves 10.

[0035] Under the guidance and limiting of the sliding blocks 9 and the sliding grooves 10, the sliding direction and sliding distance of the extension cylinder 7 in the storage cylinder 8 can be limited, preventing the extension cylinder 7 from being separated from the storage cylinder 8 due to the excessive rebound force of the spring 11, and ensuring the stability of the extension cylinder 7 operation and the tightness of the extension cylinder 7 and the storage cylinder 8 connection.

[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
