Technical Field

[0001] This utility model relates to the field of storage device technology, specifically to a storage component for early fish resource samples. Background Technology

[0002] Early fish resources refer to fish resources in the three early life stages: egg, larva, and juvenile. Their abundance can influence changes in fish population size and age structure, and is of great significance for replenishing fishery resources. Conducting early fish resource surveys is fundamental work for understanding the current status of fishery resources, studying the patterns of fish population and quantity changes, and assessing the condition of the aquatic ecological environment. It is an indispensable and crucial link in aquatic ecological protection and restoration.

[0003] During early fish resource surveys, it is necessary to preserve collected fish eggs and fry to support subsequent identification of egg and fry species and calculation of early resource quantities. Currently, EP tubes (2ml or 5ml) are typically used to preserve the collected fish egg and fry samples, and a certain number of EP tubes are then placed in centrifuge racks for transport.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a technical solution: a fish early resource sample storage component, including a first fixing seat 1, a second fixing seat 2, a placement groove 3, a plastic centrifuge tube 4, a placement component, a hinge 5, and a closing component.

[0025] Preferably, the top of the first fixing seat 1 and the second fixing seat 2 are evenly provided with several sets of placement slots 3. Number plates are provided on one side of the placement slot 3 and on the top of the first fixing seat 1 and the top of the second fixing seat 2. Plastic centrifuge tubes 4 are adapted to be placed inside the placement slots 3. A placement component for placing plastic centrifuge tubes 4 is provided below the plastic centrifuge tubes 4 and inside the placement slot 3. Two sets of hinges 5 are provided on both sides of one end of the first fixing seat 1. One end of the first fixing seat 1 is rotatably connected to one end of the second fixing seat 2 through the two sets of hinges 5. A closing component for closing one end of the first fixing seat 1 and the second fixing seat 2 is provided between the other end of the first fixing seat 1 and the other end of the second fixing seat 2.

[0026] Specifically, through the combined use of hinge 5 and the closing component, the closing component is used to connect or open one end of the first fixing seat 1 and one end of the second fixing seat 2, thereby folding the first fixing seat 1 and the second fixing seat 2 together. This makes it convenient to fold and carry the device, solving the problem that the device needs to occupy a lot of space for carrying. The operation is convenient and quick. At the same time, after the device is folded, the top of the first fixing seat 1 and the top of the second fixing seat 2 come into contact, which allows the tops of the plastic centrifuge tubes 4 placed inside the placement slot 3 to be squeezed against each other, preventing the samples inside the plastic centrifuge tubes 4 from shaking during transportation, preventing sample leakage, and ensuring the safety of early fish resource samples.

[0027] Preferably, the mounting components include: a damping sponge block 6, a sliding plate 7, a limiting block 8, a limiting groove 9, and a first telescopic spring 10. The damping sponge block 6 is fixedly installed on the upper end of the inner wall of the placement groove 3. The sliding plate 7 is adapted to be installed at the corresponding position below the damping sponge block 6 and inside the placement groove 3. Two sets of limiting blocks 8 are fixedly installed at both ends of the sliding plate 7. Two sets of limiting grooves 9 are opened on both sides of the inner wall of the placement groove 3. The interior of the limiting groove 9 is adapted to the surface of the limiting block 8, and the limiting block 8 is slidably connected to the inner wall of the limiting groove 9. The first telescopic spring 10 is fixedly installed on the inner wall at the lower end of the limiting groove 9. The upper end of the first telescopic spring 10 is fixedly connected to the bottom of the sliding plate 7.

[0028] Specifically, through the combined use of the damping sponge block 6, sliding plate 7, limiting block 8, limiting groove 9, and first telescopic spring 10, the damping sponge block 6 fixes the plastic centrifuge tube 4 inside the placement groove 3. The bottom of the plastic centrifuge tube 4 contacts the top of the sliding plate 7. Then, the first fixing seat 1 and the second fixing seat 2 fold together, causing the top of the plastic centrifuge tube 4 placed on the upper end of the first fixing seat 1 and the second fixing seat 2 to press against each other. Combined with the elastic force of the first telescopic spring 10, the plastic centrifuge tube 4 can be firmly fixed inside the placement groove 3, which can prevent the sample inside from leaking or evaporating due to poor sealing.

[0029] Preferably, the closing assembly includes: a fixing block 11, a fixing groove 12, a mounting block 13, and a limiting mechanism. Two sets of fixing blocks 11 are fixedly installed at both ends of one side of the first fixing seat 1. A fixing groove 12 is provided on one side of the fixing block 11. Two sets of mounting blocks 13 are fixedly installed at both ends of one side of the second fixing seat 2. The mounting block 13 and the fixing groove 12 are adapted to each other. A limiting mechanism is provided between the mounting block 13 and the fixing block 11. The mounting block 13 is installed in the inner cavity of the fixing groove 12 through the limiting mechanism.

[0030] Preferably, the limiting mechanism includes: a limiting rod 14, a limiting plate 15, a second telescopic spring 16, and a limiting hole 17. The limiting rod 14 is slidably connected to the inside of the fixing block 11. The limiting plate 15 is fixedly connected to the surface of the limiting rod 14 and located inside the fixing block 11. The second telescopic spring 16 is provided on one side of the limiting plate 15 and on the surface of the limiting rod 14. The limiting hole 17 is opened through one side of the mounting block 13. The inside of the limiting hole 17 is adapted to one end of the limiting rod 14, and one end of the limiting rod 14 is inserted into the inner cavity of the limiting hole 17.

[0031] Specifically, by using the limiting rod 14, the limiting plate 15, the second telescopic spring 16 and the limiting hole 17 together, the mounting block 13 can be installed inside the fixing groove 12 or taken out from the fixing groove 12. The operation is simple, convenient and quick, and it is easy to connect one end of the first fixing seat 1 to one end of the second fixing seat 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
