[0025] Example

[0026] This embodiment provides a stability test chamber, such as Figures 1-4 As shown, the test chamber includes a housing 1, a shelf 2, and a door 3. The housing 1 serves as the outer shell of the entire test chamber, providing structural support and a closed space to maintain the internal temperature and humidity environment. The shelf 2 is horizontally placed inside the housing 1. The door 3 is used to open and close the housing 1 to allow operators to place or remove medicines. The shelf 2 is used to place medicines or samples to be tested. A first baffle 4 is provided on the side of the shelf 2 near the door 3 to prevent medicines from slipping during the opening and closing of the door 3. A fixing rod 5 is vertically installed on one side of the first baffle 4, and a trapezoidal plate 6 is installed at the upper end of the fixing rod 5. The fixing rod 5 provides support and connection points for the trapezoidal plate 6, ensuring the stability and positional accuracy of the trapezoidal plate 6, and providing a foundation for the subsequent setting of the first connecting rod 7 and the second connecting rod 8.

[0027] The upper end of the trapezoidal plate 6 is hingedly connected to the bottom end of the first connecting rod 7, the lower end of the trapezoidal plate 6 is hingedly connected to the bottom end of the second connecting rod 8, the top end of the first connecting rod 7 is hingedly connected to the top end of the fixed frame 9 away from the cabinet door 3, the top end of the second connecting rod 8 is hingedly connected to the bottom end of the fixed frame 9 away from the cabinet door 3, the side of the fixed frame 9 close to the cabinet door 3 is fixedly connected to the second baffle 10, the side of the second baffle 10 close to the cabinet door 3 is provided with a handle 11, the first connecting rod 7 and the second connecting rod 8 are used for connecting the trapezoidal plate 6 and the fixed frame 9 respectively, the first connecting rod 7, the second connecting rod 8, the trapezoidal plate 6 and the fixed frame 9 form a four-connecting-rod mechanism, and the fixed frame 9 is allowed to move within a certain range. Because the side of the fixed frame 9 close to the cabinet door 3 is fixedly connected to the second baffle 10, that is, the position of the second baffle 10 is accurately controlled through the movement of the four-connecting-rod mechanism, so as to adapt to different operation requirements.

[0028] The movement of the second baffle 10 can be controlled through the handle 11; the first baffle 4 and the second baffle 10 are kept at a distance to form a channel, so that an operator can stretch out an arm to take medicine, or the second baffle 10 and the first baffle 4 form a closed vertical plane to reduce the overflow of cold air, and when the cabinet door 3 is opened, the second baffle 10 and the first baffle 4 form an "air buffer layer" to reduce the direct convection of cold and hot air, thereby reducing the influence of the external environment on the temperature in the cabinet 1 and helping to protect the stable environment established in the cabinet 1.

[0029] The first baffle 4 is vertically arranged with the storage rack 2, and the trapezoidal plate 6 is perpendicular to the first baffle 4. This vertical design scheme ensures that the first baffle 4 can effectively prevent the medicine from falling during the opening and closing of the cabinet door 3, and at the same time provides stable vertical support for the trapezoidal plate 6, ensuring the accuracy of the connection and movement of the trapezoidal plate 6,

[0030] When the second baffle 10 moves to the lowermost end, the second baffle 10 is on the same plane as the first baffle 4, and there is no gap between the first baffle 4 and the second baffle 10, and when the second baffle 10 moves to the lowermost end, the first baffle 4 forms a completely closed vertical plane, effectively preventing the overflow of cold air and reducing the influence of the external environment on the temperature in the cabinet 1.

[0031] The front projection of the first baffle 4 and the second baffle 10 is a rectangle, and the front projection of the rectangle ensures that the coverage area of the first baffle 4 and the second baffle 10 is maximized, which can more effectively prevent the overflow of cold air.

[0032] The cross section of the trapezoidal plate 6 is a right trapezoid, wherein the vertical right angle side of the trapezoidal plate 6 is connected to the fixed rod 5, and the design of the right trapezoid makes the trapezoidal plate 6 more stable when connected to the fixed rod 5.

[0033] The trapezoidal plate 6 and the fixed rod 5 are integrally formed, the integrally formed design eliminates looseness and failure problems caused by connection of multiple components, improves the overall strength and durability of the components, reduces maintenance and replacement frequency, and ensures the stability and reliability of the equipment during long-term use.

[0034] The width of the first baffle 4 and the width of the second baffle 10 are the same, and the same width ensures that the first baffle 4 and the second baffle 10 can be completely aligned when closed, forming a seamless closed plane, effectively preventing cold air from overflowing, and improving the closing effect.

[0035] The bottom of the shelf 2 can be optionally provided with a support leg 12, which provides additional support for the shelf 2 and ensures the stability of the shelf 2 when carrying drugs, which is beneficial to improve the adaptability and stability of the device, and ensure the safety of the drugs and the reliability of the data during the test.

[0036] The use process of the stability test box is as follows:

[0037] (1) Open the door 3: the operator needs to manually open the door 3 for placing or taking out the drugs.

[0038] (2) Control the movement of the second baffle 10: by pulling or pushing the handle 11, the operator can control the movement of the second baffle 10. The specific operation is as follows: when placing or taking out the drugs, the operator pulls the handle 11 to move the second baffle 10 away from the first baffle 4, forming a passage. At this time, the operator can stretch his arm through the passage to take or place the drugs. When the drug placement or taking out is completed, the operator pushes the handle 11 to move the second baffle 10 to the same plane as the first baffle 4, forming a closed vertical plane, avoiding direct heat exchange between the drugs and the air outside the door 3, and reducing the influence of the external environment on the temperature in the box 1.

[0039] (3) Close the door 3: after completing the placement or taking out of the drugs, the operator needs to manually close the door 3 to ensure the stability of the environment in the box 1.

[0040] The support leg 12 is a conventional setting in the prior art, and those skilled in the art can select appropriate devices or settings according to the above description to achieve "the bottom of the shelf 2 can be optionally provided with a support leg 12."

[0041] The Figure 1 The present application only shows a single shelf 2 placement situation, and in normal use state, several shelves 2 will be placed in the vertical direction in the box 1.

[0042] The length and the curvature and the number of the lines of the first connecting rod 7 and the second connecting rod 8 and the shelf 2 in the drawings are only for illustration, and those skilled in the art can make adaptive adjustment according to the actual use.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
