Description

Technical Field

[0001] This utility model relates to the field of liquid nitrogen tank technology, specifically to a footrest step for storing liquid nitrogen tanks. Background Technology

[0002] In fields such as biomedicine and materials science, liquid nitrogen tanks are widely used as cryogenic storage devices to preserve biological samples, cells, vaccines, and special materials. Because liquid nitrogen tanks are usually quite tall, and to ensure good cryogenic storage, their openings are often designed at the top of the tank.

[0003] When retrieving or placing items at higher positions within a liquid nitrogen tank, height limitations often force operators to tiptoe and bend over, making the process inconvenient. Additional tools, such as stools, are frequently needed, but these can easily tip over, posing a significant safety hazard and are unsuitable for use and storage in the relatively confined work area around the liquid nitrogen tank. Therefore, it is necessary to address these technical issues and improve the ease of access when storing items in liquid nitrogen tanks. In this regard, we propose a footrest for liquid nitrogen tank storage. Utility Model Content

[0008] The foot step includes a first-stage step plate and a second-stage step plate that are rotatably installed on the underside of the first horizontal pressure plate and the second horizontal pressure plate, respectively.

[0009] The storage unit includes a storage tray inserted into the side shelf on either side, and an outer baffle is fixedly installed at the outer end of the storage tray.

[0010] Preferably, the storage unit includes an L-shaped tray that is symmetrically arranged and detachably mounted on the second horizontal pressure plate, and a slide rail is mounted on the L-shaped tray;

[0011] The storage tray is equipped with a slider that is slidably mounted on the slide rail.

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.

[0031] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0032] In this embodiment, the liquid nitrogen tank storage foot step is designed for easy folding. Figure 4 The structure shown needs to be as follows: Figure 1 and Figure 2 The installation position shown maintains a certain height off the ground, specifically including:

[0033] Two side frame plates 2 are fixedly connected by a first horizontal pressure plate 6 and a second horizontal pressure plate 7 set at the upper and lower ends. A first-level step plate 3 and a second-level step plate 4 are rotatably installed on the lower side of the first horizontal pressure plate 6 and the second horizontal pressure plate 7. The first-level step plate 3 and the second-level step plate 4 can maintain the horizontal support force of the step based on the limiting effect of the first horizontal pressure plate 6 and the second horizontal pressure plate 7. The rotation axis of the first-level step plate 3 and the second-level step plate 4 is located at the outer end of the first horizontal pressure plate 6 and the second horizontal pressure plate 7, which does not affect the rotation and folding.

[0034] To facilitate the storage and folding of the first-level step plate 3 and the second-level step plate 4, a connecting rod 5 is rotatably installed between the outer ends of the first-level step plate 3 and the second-level step plate 4, enabling the connection from... Figures 3 to 4 The rotating and folding action.

[0035] In this embodiment, an insertion hole is provided on one side shelf plate 2 to insert a storage unit 8, which facilitates the storage of liquid nitrogen tank components, specifically including, for example... Figure 5 , Figure 6 The storage tray 81 with an outer baffle 84 fixedly installed at the outer end of the structure shown, wherein a handle 85 is installed at the outer end of the outer baffle 84.

[0036] To maintain the horizontal insertion function of the storage tray 81 and obtain limiting capability, two symmetrically arranged L-shaped trays 86 are installed on the second horizontal pressure plate 7. A slide rail 88 is detachably installed on the inner side of the vertical plate of the L-shaped tray 86, and a rubber gasket 87 is fitted around the outer edge of the L-shaped tray 86; the storage tray 81... Figure 6 As shown, by installing a slider 89 in the provided groove 811 and sliding it along the slide rail 88, in order to avoid directly pulling out the storage tray 81 and to facilitate the disassembly and assembly of the storage tray 81 for subsequent maintenance and replacement of parts, a protrusion 82 is fixedly installed on the inner end side of the storage tray 81, and a retaining plate 83 is inserted into the protrusion 82. The retaining plate 83 can play a blocking and limiting role in the process of pulling out the storage tray 81.

[0037] 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.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
