Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This embodiment provides a basket locking mechanism, such as Figures 1-4 As shown, this mechanism is used to detachably secure the basket 3. The basket 3 is typically used to carry biological culture containers such as petri dishes and culture flasks. By employing the locking mechanism provided in this embodiment, the basket 3 can be quickly installed and removed, thereby improving the convenience and efficiency of experimental operations.

[0021] Specifically, as shown in the appendix Figure 1 As shown, the basket locking mechanism in this embodiment mainly includes a positioning base 1 and one or more telescopic locking mechanisms 2 disposed on the side of the positioning base 1. At least one telescopic locking mechanism 2 is configured to extend and retract elastically relative to the positioning base 1. Specifically, the telescopic locking mechanism 2 is adapted to elastically engage with the preset mating part on the basket when the basket with the preset mating part is pressed against the positioning base 1, thereby detachably locking the basket onto the positioning base 1. To adapt to the high humidity or periodic disinfection environment inside the biological culture chamber, the positioning base 1 can be made of a material with sufficient rigidity and corrosion resistance, such as 304 or 316L stainless steel. Accordingly, the surface of the positioning base 1 can be polished or passivated to reduce the adhesion of microorganisms. The positioning base 1 is securely installed on the inner wall or bottom plate of the biological culture chamber by bolts, welding, or other suitable fixing methods, providing a stable and reliable installation reference for the entire locking mechanism.

[0022] Understandably, the number and layout of the telescopic locking mechanism 2 can be adjusted according to the size, weight and required locking force of the basket. For example, other layouts such as rectangular evenly distributed on all four sides or circular evenly distributed can also be used.

[0023] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, the telescopic locking mechanism 2 includes a mounting housing 21, an elastic element 23 housed within the mounting housing 21, and a locking element 22 connected to the elastic element 23. One end of the locking element 22 can extend or retract from the mounting housing 21 under the action of the elastic element 23. This telescopic locking mechanism 2 can be a standard or custom-made spring plunger, which is compact and highly reliable.

[0024] The mounting housing 21 is typically made of a metal material (such as brass, stainless steel, or carbon steel), and its outer surface may be threaded to allow it to be screwed into a pre-drilled threaded hole on the positioning base 1 for quick installation and replacement. The mounting housing 21 and the positioning base 1 can also be connected via an interference fit. The interior of the mounting housing 21 is a hollow structure to accommodate part of the elastic element 23 and the clamping element 22. The elastic element 23 provides elastic tension and can be a helical compression spring in this embodiment. This spring is preferably made of a highly elastic material such as spring steel and undergoes appropriate heat treatment to ensure good elasticity and fatigue resistance. One end of the elastic element 23 abuts against the inner bottom wall of the mounting housing 21, while the other end acts on the clamping element 22. The clamping element 22 is the component that directly contacts and engages with the basket 3. A portion of it is housed within the mounting housing 21 and connected to the elastic element 23, while the other end extends out of the opening of the mounting housing 21. When not subjected to external force, the clamping member 22 remains in the extended state under the elastic force of the elastic member 23; when subjected to external axial pressure, the clamping member 22 will overcome the elastic force of the elastic member 23 and retract inward into the mounting housing 21.

[0025] In a preferred embodiment, to facilitate smoother installation of the basket and reduce friction and wear, the clamping member 22 extends out of one side of the mounting housing 21 in a smooth hemispherical shape. When this hemispherical head contacts the mating part of the basket, it can smoothly guide the vertical pressing pressure into a radial force that retracts the clamping member 22.

[0026] In a preferred embodiment, a retaining ring 24 is provided at the end of the mounting housing 21 near the protruding end of the clamping member 22, and the outer diameter of the retaining ring 24 is larger than the outer diameter of the mounting housing 21.

[0027] In this embodiment, the mounting housing 21 of the telescopic clamping mechanism 2 has a retaining ring 24 integrally formed or securely fixed by welding, interference fit, or other means near the protruding end of the clamping member 22. The retaining ring 24 has a structure similar to a flange, with its outer diameter significantly larger than the outer diameter of the main body of the mounting housing 21. When the telescopic clamping mechanism 2 is installed on the positioning base 1, the retaining ring 24 is engaged with the outer side of the positioning base 1, providing precise axial positioning. This improves the maintainability of the device, facilitating the disassembly and assembly of the telescopic clamping mechanism 2 when it fails due to fatigue or wear and needs to be replaced.

[0028] In a preferred embodiment, the positioning base 1 is rectangular, and the telescopic clamping mechanism 2 is installed on two adjacent sides of the positioning base 1 so that the telescopic clamping mechanism 2 can push the positioning base 1 to move towards the two sides of the locking positioning port 31 of the basket 3, so that the two sides of the positioning base 1 without the telescopic clamping mechanism 2 can fit tightly with the locking positioning port 31, thereby increasing the stability of the connection between the locking positioning port 31 of the basket 3 and the basket locking mechanism of this embodiment.

[0029] In a preferred embodiment, an inclined surface 11 is provided on the top surface of the two sides of the positioning base 1 where the telescopic locking mechanism 2 is not installed. The inclined surface 11 makes the thickness of the middle of the positioning base 1 greater than the thickness of its sides. The inclined surface 11 allows the locking positioning port 31 on the basket 3 to slide down along the inclined surface 11, which facilitates the positioning between the locking positioning port 31 on the basket 3 and the positioning base 1.

[0030] In a preferred embodiment, a mounting hole 12 is provided on the positioning base 1, and the mounting hole 12 is disposed through the thickness direction of the positioning base 1. There may be two mounting holes 12, which are arranged along the length direction of the positioning base 1. The mounting holes 12 allow connectors such as bolts to pass through so as to install the positioning base 1 in the biological culture chamber.

[0031] In a preferred embodiment, the positioning base 1 is elongated, with a telescopic locking mechanism 2 disposed on one short side. Five telescopic locking mechanisms 2 are disposed on one long side of the positioning base 1, evenly distributed across the base. This L-shaped layout provides limiting and locking forces to the basket 3 in two mutually perpendicular directions, effectively preventing the basket 3 from shifting or rotating after installation, thus ensuring its positioning accuracy and stability.

[0032] First, this application achieves rapid installation and disassembly of the basket through the elastic engagement of the telescopic locking mechanism with the basket's mating part. The operator only needs to press the basket downwards to lock it and pull it upwards to remove it, achieving a plug-and-play effect. This greatly improves operational convenience and work efficiency, solving the problems of cumbersome and time-consuming disassembly and assembly in existing technologies. Second, by setting multiple elastic locking components on the positioning base, a stable and reliable multi-point locking can be formed with the basket, effectively preventing the basket from shaking during movement or vibration, improving positioning accuracy and stability, and overcoming the defect of inaccurate positioning due to wear after long-term use of existing elastic devices. Finally, the locking mechanism of this application has a simple structure and can use standardized parts such as ball-head plungers or integrated buckles, facilitating standardization and modular design. This not only reduces production and maintenance costs but also allows for interchangeability between different baskets, achieving good versatility.

[0033] This embodiment also provides a biological culture chamber, such as Figure 4 As shown, the basket includes the aforementioned basket locking mechanism and basket 3. A locking positioning port 31 is provided on the bottom plate of basket 3. The size of the locking positioning port 31 is larger than the outline size of the positioning base 1, but smaller than the maximum outline size formed when the telescopic clamping mechanism 2 is extended. That is, the length of the locking positioning port 31 is greater than the length of the positioning base 1 and less than the length of the clamping member 22 when it extends out of the short side of the positioning base 1, and the width of the locking positioning port 31 is greater than the width of the positioning base 1 and less than the width of the clamping member 22 when it extends out of the long side of the positioning base 1.

[0034] In this embodiment, the shape and size of the locking positioning port 31 are precisely designed to ensure reliable engagement with the basket locking mechanism. Specifically, the outline dimension of the locking positioning port 31 is larger than the overall outline dimension of the positioning base 1, so that the positioning base 1 can pass through the locking positioning port 31; at the same time, the outline dimension of the locking positioning port 31 is smaller than the maximum outline dimension formed by all the telescopic locking mechanisms 2 in their naturally extended state. That is to say, these locking members 22 can be locked at the edge of the locking positioning port 31, thereby providing effective support and limiting for the bottom plate of the basket 3.

[0035] The biological culture chamber in this embodiment also includes a turntable 4, and multiple basket locking mechanisms are evenly arranged around the turntable 4. Five or six basket locking mechanisms can be set, and one basket can be installed on each basket locking mechanism. Each basket locking mechanism is the same size, so the baskets can be installed on different basket locking mechanisms and interchanged at any position, thus achieving universality.

[0036] When installing the basket, the operator picks up the basket 3, aligns the locking positioning port 31 at its bottom roughly with the basket locking mechanism below, and presses it vertically downwards. During the pressing process, the inner wall of the locking positioning port 31 on the basket 3 first contacts the hemispherical locking members 22 of each telescopic locking mechanism 2. As the basket 3 continues to be pressed down, the locking members 22 are subjected to pressure from the basket 3, which overcomes the preload of the internal elastic member 23, causing the locking members 22 to be pressed into their respective mounting housings 21, temporarily retracting to a position flush with or lower than the side of the positioning base 1. Because all telescopic locking mechanisms 2 are compressed, the basket 3 can move downwards smoothly.

[0037] When the basket 3 is pressed into place, driven by the elastic potential energy stored in each elastic element 23, all the locking elements 22 immediately and automatically pop outward and abut against the inner wall of the locking positioning port 31 on the basket 3, so that the basket 3 is firmly locked on the positioning base 1. The L-shaped layout ensures that the basket is accurately positioned in both dimensions and cannot wobble.

[0038] When removing the basket, the operator grasps the handle or edge of the basket 3 and applies a sufficiently large vertical upward pulling force. Under this pulling force, the lower surface of the basket 3's base plate, located at the edge of the locking positioning port 31, will press against the hemispherical locking member 22. Similar to the installation process, the locking member 22 will be compressed again and retracted into the mounting housing 21, thereby releasing the lock on the basket 3. Once all locking members 22 are compressed, the basket 3 can be smoothly lifted upward and removed from the basket locking mechanism.

[0039] This embodiment, through the aforementioned structure, enables quick insertion and removal of the basket. The entire installation and disassembly process requires no tools, is intuitive, labor-saving, and time-efficient, thus improving work efficiency. Simultaneously, the multi-point elastic locking method ensures connection stability and positioning reliability.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
