Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1-7 This utility model provides a technical solution: an intelligent sample retention cabinet, including a cabinet body 1 and a U-shaped frame 7. Multiple positioning holes 5 are provided on both the left and right sides of the cabinet body 1. A guide groove 4 is provided on the rear side of the cabinet body 1. A slot 9 is provided on the front side of the U-shaped frame 7. A protrusion 8 is fixed in the middle of the rear side of the U-shaped frame 7. A placement tray 6 is slidably inserted into the slot 9. Operation grooves 12 are provided at both the left and right ends of the front side of the U-shaped frame 7. Square grooves 11 communicating with the operation grooves 12 are respectively provided at the front ends of the left and right sides of the U-shaped frame 7. Positioning devices are provided inside both square grooves 11. The positioning component includes a positioning post 14, a square plate 15, and a limiting disc 16. The positioning post 14 is slidably connected to the middle of the square plate 15. The square plate 15 is fixed to the inner wall of the square groove 11. A return spring 17 is fixed to the right side of the square plate 15. The limiting disc 16 is fixed to the right end of the positioning post 14. The right end of the return spring 17 is fixed to the limiting disc 16. A lever 13 is fixed to the front of the limiting disc 16, and the lever 13 passes through the operating groove 12. This design solves the problem that most of the shelves in the current sample retention cabinets are fixed structures and cannot be adjusted in height. This results in low space utilization when storing sample boxes of different sizes. If the container is too short, it wastes the upper space; if the container is too tall, it cannot be placed. In addition, the disassembly and assembly steps are cumbersome, making it inconvenient to clean quickly and adjust the layout.
[0023] As the first embodiment of this utility model: Multiple U-shaped frames 7 are provided, and multiple protrusions 8 are slidably installed inside the guide groove 4. Multiple U-shaped frames 7 mean that multiple placement trays 6 can be installed, realizing vertical layering of the internal space of the cabinet 1, greatly improving space utilization and sample storage capacity. Each U-shaped frame 7 can slide independently up and down within the guide groove 4 via its protrusions 8, allowing the height of each layer to be flexibly adjusted to accommodate sample containers of different heights. The U-shaped frames 7 are made of iron, and a magnetic sheet 10 is fixed to the rear side of the placement tray 6. When the placement tray 6 is inserted into the slot 9, the magnetic sheet 10 will attract the iron U-shaped frame 7. This magnetic force improves the stability of the placement tray 6, preventing it from accidentally sliding out or shifting. The diameter of the positioning post 14 is smaller than the diameter of the positioning hole 5, making it easier and smoother to insert the positioning post 14 into the positioning hole 5.
[0024] The front of cabinet 1 is hinged with an observation door 2. The observation door 2 has lock cylinders 3 and latches on both the upper and lower left sides. Lock seats are also located on the upper and lower left sides of the front of cabinet 1. The double lock cylinders 3 (one on the top and one on the bottom) significantly enhance the cabinet's security, effectively preventing unauthorized personnel from opening the sample retention cabinet. A handle is fixed to the front left side of the observation door 2, providing a clear point of leverage for easy opening and closing by staff.
[0025] As a second embodiment of this utility model: First, to adjust the height of the U-shaped frame 7, the operator needs to press the levers 13 located at both ends of the front side of the U-shaped frame 7 simultaneously with both hands (i.e., towards the rear of the cabinet 1). This action causes the levers 13 to drive the limiting disc 16, thereby compressing the return spring 17 and forcing the positioning pin 14, which is fixed to the limiting disc 16, to completely retract from the current positioning hole 5 on the side wall of the cabinet 1, thus releasing the horizontal locking of the U-shaped frame 7. Next, while keeping the levers 13 pressed down, the operator can use the precise cooperation between the protrusion 8 fixed in the middle of the rear side of the U-shaped frame 7 and the guide groove 4 on the rear side inside the cabinet to smoothly slide the entire U-shaped frame 7 upward or downward. The guide groove 4 not only ensures the smoothness and stability of the movement process, but also prevents the U-shaped frame 7 from shifting in the front-back direction during adjustment. When the U-shaped frame 7 is moved to the desired height and the positioning pin 14 is aligned with the positioning hole 5 of the corresponding height, the levers 13 can be released. At this time, the compressed return spring 17 will release its elastic potential energy, pushing the limiting disc 16 and the positioning pin 14 forward to reset, so that the positioning pin 14 is accurately embedded in the new positioning hole 5.
[0026] Next, the placement tray 6 is installed. The operator holds the placement tray 6 and aligns its rear end (the end with the fixed magnetic piece 10) with the specially designed slot 9 on the front side of the U-shaped frame 7. The placement tray 6 is then pushed horizontally into the cabinet. During this process, the magnetic piece 10 fixed to the rear side of the placement tray 6 gradually approaches the iron U-shaped frame 7. The magnetic attraction between the two helps guide the placement tray 6 to fully enter the bottom of the slot 9 and keeps it stable during daily operation vibrations, preventing accidental slippage. This design enables quick and accurate installation of the placement tray 6.
[0027] When it is necessary to retrieve or place samples, the operator only needs to hold the front end of the placement tray 6 with their hand and apply a horizontal outward pulling force to overcome the weak attraction of the magnetic sheet 10, easily pulling the entire placement tray 6 out of the slot 9 for sample storage or retrieval. After storage or retrieval, simply push it back in; the operation is extremely simple.
[0028] Finally, after all sample retention operations are completed, the observation door 2 should be closed, and the lock cylinder 3 located on the upper and lower sides of the observation door 2 should be rotated using a special key so that the lock tongue can reliably extend into the corresponding lock seat on the front side of the cabinet 1, thereby achieving double locking of the sample retention cabinet and ensuring the safety of the internal samples.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
