Description

Technical Field

[0001] The utility model relates to the technical field of fish specimens, and particularly relates to a fish specimen bottle. Background Art

[0002] In the field of ichthyological research, fish samples are often collected for making specimens, which is convenient for more detailed observation, photographing and display of the morphological characteristics of fish in later research; in the environment where fish specimens are preserved, especially when the sealing performance of the specimen bottle is not tight enough, these gases will gradually penetrate into the bottle. Among them, oxygen and water vapor in the air are the most influential factors on the preservation liquid. As a strong oxidant, oxygen can react with organic substances in the preservation liquid, resulting in the oxidation and deterioration of the solution. This will not only change the chemical properties of the preservation liquid and reduce its anti-corrosion effect, but may also trigger a series of adverse chemical reactions, such as promoting the growth of microorganisms, accelerating the fading and decay of the specimen. After water vapor enters the specimen bottle, it will increase the humidity of the preservation liquid, providing favorable conditions for the growth of microorganisms. At the same time, the increase in moisture will also affect the concentration and stability of the preservation liquid. The deteriorated preservation liquid cannot effectively inhibit the growth of microorganisms and prevent the oxidation of fish specimens, resulting in the fading, deformation or even decay of fish specimens. This not only destroys the morphological integrity of the specimen, but also affects its scientific value and ornamental value. In view of this, a fish specimen bottle is proposed. Content of the Utility Model

[0003] To solve the above at least one technical defect, the utility model provides a fish specimen bottle, which includes a bottle body. An inner tightening sleeve is arranged above the bottle body, and an outer tightening sleeve is connected to the middle of the inner tightening sleeve.

[0004] Further, an extrusion hole is arranged in the middle of the inner tightening sleeve. A glue layer is connected below the inner tightening sleeve, and a liquid-contact plate is connected below the glue layer. The extrusion hole is connected to the outer tightening sleeve.

[0005] Further, the outer diameters of the glue layer and the liquid-contact plate are equal to the inner diameter of the bottle body. The top of the glue layer is fixedly connected to the inner tightening sleeve, and the bottom of the glue layer is fixedly connected to the liquid-contact plate. The inner tightening sleeve and the liquid-contact plate are made of corrosion-resistant alloy materials, and the glue layer is made of flexible rubber material.

[0006] Further, the outer diameter of the inner tightening sleeve is slightly larger than the inner diameter of the bottle body.

[0007] Further, internal threads are arranged on the extrusion hole, and a connecting convex column with external threads is arranged at the bottom of the outer tightening sleeve. The extrusion hole is threadedly connected to the connecting convex column, and a matching handle is also arranged above the outer tightening sleeve.

[0008] Further, a reinforcing sleeve for reinforcement is also arranged above the bottle body.

[0009] Beneficial effects: Inject a formalin solution into the prepared fish specimen. After injecting the fixing solution, gently place the fish specimen into the bottle body containing the specimen solution. At this time, place the fish with its head down and tail up to reduce the movement and damage of the fish body in the bottle. Put the inner tight sleeve over the upper part of the bottle body, and gradually screw the externally threaded outer tight sleeve into the extrusion hole of the inner tight sleeve. At this time, the space inside the inner tight sleeve is gradually compressed by the connecting convex column at the bottom of the outer tight sleeve, which will cause the air pressure inside the inner tight sleeve to squeeze against the rubber layer of the inner tight sleeve. Since the rubber layer is made of flexible rubber, the contact wall between the outside of the rubber layer and the bottle body will gradually become tight. The liquid contact plate and the top of the inner tight sleeve are made of corrosion-resistant alloy materials and will not deform after the space inside the inner tight sleeve is squeezed, thus forming a double-sealing effect with the outer tight sleeve, solving the problem of the fish specimen rotting due to the insufficient tightness of the specimen bottle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] This embodiment provides a fish specimen bottle, which includes a bottle body 1. An inner tight sleeve 2 is arranged above the bottle body 1, and an outer tight sleeve 3 is connected to the middle of the inner tight sleeve 2; Refer to Figure 1 and Figure 2 , an extrusion hole 203 is arranged in the middle of the inner tight sleeve 2. A rubber layer 201 is connected below the inner tight sleeve 2, and a liquid contact plate 202 is connected below the rubber layer 201. And the extrusion hole 203 is connected to the outer tight sleeve 3. The outer diameters of the rubber layer 201 and the liquid contact plate 202 are equal to the inner diameter of the bottle body 1. And the top of the rubber layer 201 is fixedly connected to the inner tight sleeve 2, and the bottom of the rubber layer 201 is fixedly connected to the liquid contact plate 202. The inner tight sleeve 2 and the liquid contact plate 202 are made of corrosion-resistant alloy materials, the rubber layer 201 is made of flexible rubber material, the outer diameter of the inner tight sleeve 2 is slightly larger than the inner diameter of the bottle body 1. Inner threads are provided on the extrusion hole 203, and a connecting convex column 301 with external threads is arranged at the bottom of the outer tight sleeve 3. The extrusion hole 203 is threadedly connected to the connecting convex column 301. And a matching handle is further arranged above the outer tight sleeve 3; A reinforcement sleeve 101 for reinforcement is also arranged above the bottle body 1;

[0016] In a specific embodiment, a formalin solution is injected into the prepared fish specimen. After injecting the fixing solution, the fish specimen is gently placed into the bottle body containing the specimen solution. At this time, the fish's head is placed downward and the tail is placed upward to reduce the movement and damage of the fish body in the bottle. The inner tightening sleeve 2 is sleeved over the upper part of the bottle body 1, and the externally threaded outer tightening sleeve 3 is gradually screwed into the extrusion hole 203 of the inner tightening sleeve 2. At this time, the space inside the inner tightening sleeve 2 is gradually compressed by the connecting convex column 301 at the bottom of the outer tightening sleeve 3, which will cause the air pressure inside the inner tightening sleeve 2 to be extruded towards the glue layer 201 of the inner tightening sleeve 2. Since the glue layer 201 is made of flexible rubber, the contact wall between the outside of the glue layer 201 and the bottle body 1 will gradually become tight. The liquid contact plate 202 and the top of the inner tightening sleeve 2 are made of corrosion-resistant alloy material, so that they will not deform after the space inside the inner tightening sleeve 2 is compressed, thus forming a double-closed effect with the outer tightening sleeve 3 and solving the problem of the fish specimen rotting due to the insufficient tightness of the specimen bottle's seal.
