Description

Technical Field

[0001] The utility model relates to a cage, in particular to a yellow eel cage. Background Art

[0002] In the field of catching eels, traditional catching tools are mostly long cylindrical cages, which are usually designed with only one entrance. Such a design has many inconveniences when catching eels. First, the single entrance limits the eel's entry path, making the catching efficiency of eels low. Secondly, due to the restrictions on the shape and position of the entrance, the eel may feel difficult or uneasy when trying to enter the cage due to the unreasonable design of the entrance, further reducing the success rate of catching. At the same time, the traditional catching tools are small in size, which is not conducive to the survival of the eel after being caught.

[0003] Therefore, in order to improve the capture efficiency and success rate of yellow eels and the survival comfort of yellow eels after capture, it is particularly important to design a new yellow eel cage. The new yellow eel cage needs to improve the entry convenience and comfort of yellow eels as much as possible while ensuring the capture effect, thereby increasing the success rate of capture.

[0005] The technical problem to be solved by the utility model is achieved by the following technical solutions:

[0006] A yellow eel cage includes a cage body, which is formed by an upper cover body and a lower cover body clamped together by a clamping structure, the upper cover body and the lower cover body are both basin-shaped, the lower end side surfaces of the upper cover body and the lower cover body are each provided with six semicircular holes, and the outer side surfaces of the semicircular holes are provided with external threads; after the upper cover body and the lower cover body are clamped together, the semicircular holes of the upper cover body and the semicircular holes of the lower cover body form a circular inlet, a movable inlet is provided at the circular inlet, the movable inlet includes a tapered mouth and an outer edge portion, the outer edge portion is provided with an internal thread, and the movable inlet is threadedly connected to the circular inlet through the internal thread and the external thread.

[0007] The snap-fit ​​structure comprises snap buckles and snap holes on the lower end surfaces of the upper cover body and the lower cover body. The snap buckles and snap holes are respectively provided in three numbers and are spaced between adjacent semicircular holes.

[0008] The three buckles and three buckle holes on the upper cover body respectively correspond to the three buckles and buckle holes on the lower cover body and are adapted to each other.

[0009] The clamping structure is clamped in such a way that the three buckles of the upper cover body are clamped in the three clamping holes of the lower cover body, and the three buckles of the lower cover body are clamped in the three clamping holes of the upper cover body.

[0010] The lower end sides of the upper cover body and the lower cover body are both provided with concave openings corresponding to the positions of the buckles and the clamping holes.

[0011] The upper cover body, the lower cover body and the conical opening are all provided with lattice holes.

[0012] The beneficial effects of the utility model are as follows: 1. A circular inlet is formed by designing a plurality of semicircular holes, thereby increasing the entry paths for the yellow eels and improving the capture efficiency.

[0013] 2. The tapered mouth design of the movable entrance makes it smoother and more comfortable for the eel to enter the cage when trying to enter, reducing the eel's resistance and thus increasing the success rate of capture.

[0014] 3. The design of the snap-fit ​​structure makes it easy to install and disassemble the upper and lower covers, and is convenient for cleaning and maintenance. At the same time, the design of the concave mouth makes the installation of the snap-fit ​​structure simpler and more stable.

[0015] 4. The design of the lattice holes not only increases the air permeability of the cage, but also makes the cage have excellent water permeability when immersed in water.

[0016] 5. The upper cover and the lower cover are basin-shaped structures, which make the cage space larger, facilitate the movement of eels in the cage, and improve the practicality of the cage.

[0017] 6. The movable inlet is threadedly connected to the circular inlet through internal and external threads, which further enhances the stability of the connection between the upper cover and the lower cover. BRIEF DESCRIPTION OF THE DRAWINGS
