Description

Technical Field

[0001] This utility model relates to the field of automated single-unit refrigerator technology, specifically to a top quick-release structure that is easy to assemble and disassemble. Background Technology

[0002] The automated single-unit refrigerator's storage chamber is divided into a storage chamber and an equipment chamber. The storage chamber temperature needs to be controlled at -80℃ for storing frozen samples, while the equipment chamber is composed of mechanical components and is the main structure for automated sample handling. In ultra-low temperature environments, the mechanical structure is prone to failure and malfunction. Furthermore, due to the necessity of sample handling and movement, the storage chamber and equipment chamber must be kept connected. This inevitably leads to the mechanical components between the equipment chambers being prone to failure, thus requiring regular inspection or maintenance.

[0003] However, traditional equipment compartments mostly have mechanical devices directly installed inside the top cabinet of automated single-unit refrigerators. During inspection and maintenance, the storage compartment needs to be opened for a long time to disassemble the mechanical parts one by one, which can easily damage the frozen samples that need to be stored at low temperatures. Therefore, how to quickly disassemble and assemble the mechanical parts inside the equipment compartment is of great significance for maintaining the frozen storage environment of automated single-unit refrigerators, in order to avoid the problem of excessive temperature fluctuations caused by long-term openness. In view of this, we propose a top quick-release structure that is easy to disassemble and assemble. Utility Model Content

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments: This embodiment features a quick-release top structure for easy assembly and disassembly, such as... Figures 1-2 As shown in the structure, considering the need for quick assembly and disassembly of the three-dimensional sampling robotic arm 2 installed in the automated single refrigerator 1, a quick-release mounting bracket 3 is set in the storage cavity 101, and the three-dimensional sampling robotic arm 2 is installed on top in the equipment cavity 102.

[0017] Specifically, such as Figures 3-5 As shown in the structure, in this embodiment, the quick-release mounting bracket 3 includes a fixed frame installed inside the storage cavity 101. The fixed frame includes a base plate 31 detachably installed at the bottom of the storage cavity 101. The base plate 31 is provided with three cryogenic trays 311 for fixing and installing the cryogenic rack. Therefore, the stability of the cryogenic rack can be ensured when the fixed frame is stable. Vertical brackets 32 are vertically installed at the four ends of the base plate 31. In this embodiment, top brackets 34 are installed at the top of the four vertical brackets 32. In order to facilitate the quick-release plate 36 to be quickly installed and removed horizontally along the top brackets 34, the top brackets 34 are as follows: Figure 5 The configuration shown adopts a U-shaped structure with an opening near the outer end.

[0018] To improve stability, a crossbeam 33 is fixedly installed between the vertical frames 32 on both sides in this embodiment, so the fixed frame itself is structurally stable; therefore, the quick-release plate 3 can be detachably installed at the top of the fixed frame without affecting the frame. When the quick-release plate 36 is removed, the three-dimensional sampling robot arm 2 is taken out simultaneously to facilitate inspection and maintenance operations.

[0019] For easy and quick assembly and disassembly, such as Figures 3-5 As shown in the structure, a protrusion 35 is installed on the inner side of the top bracket 34, and a positioning pin 351 is provided on the protrusion 35. In order to achieve quick positioning and facilitate quick installation and fixation, two sets of limiting cams 37 are symmetrically installed on the bottom surface of the quick-release plate 36. Each set of limiting cams 37 is attached to the inner wall of the U-shaped structure. In this embodiment, the limiting cams 37 are rotated to reduce frictional resistance. At the same time, a locking block 38 is installed on the inner side of the bottom surface of the quick-release plate 36. The locking block 38 and the positioning pin 351 are inserted and positioned. Finally, the screws between the top bracket 34 and the quick-release plate 36 are tightened to complete the positioning. The overall disassembly and assembly are highly efficient.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] It will be apparent to those skilled in the art that this invention 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 essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
