DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figures 1-4 In order to solve the problem that the leech seedlings are easy to climb up the inner wall of the container and escape from the gap between the breeding box and the sealing cover, resulting in loss of seedlings and increasing the breeding cost, the following preferred technical solutions are provided:

[0022] A leech seedling breeding box with an anti-escape structure comprises a breeding box body 1, a sealing cover 2 hinged to the upper end of the breeding box body 1, an auxiliary frame 3 slidably connected to the inner wall of the breeding box body 1, a mesh main body 4 fixedly connected to the inner wall of the auxiliary frame 3, an extension rod assembly 5 fixedly connected to the lower end of the auxiliary frame 3, wherein the extension rod assembly 5 is provided in multiple groups and the multiple groups of extension rod assemblies 5 are evenly arranged about the lower wall of the auxiliary frame 3, the extension rod assembly 5 comprises an inner connecting rod 51 fixedly connected to the lower wall of the auxiliary frame 3 and an outer connecting rod 52 fixedly connected to the bottom of the cavity of the breeding box body 1, one end of the inner connecting rod 51 is located in the inner cavity of the outer connecting rod 52, an active block 53 is fixedly connected to the outer wall of the inner connecting rod 51, and the active block 53 is slidably connected to the inner wall of the outer connecting rod 52.

[0023] The inner wall of the outer connecting rod 52 is fixedly connected with a receiving block 54, the upper end of the receiving block 54 is fixedly connected with a mounting rod 55, the outer wall of the inner connecting rod 51 and the mounting rod 55 is sleeved with a return spring 56, one end of the return spring 56 is fixedly connected with the active block 53, and the other end of the return spring 56 is fixedly connected with the receiving block 54, and in the relaxed state of the return spring 56, the auxiliary frame 3 is located at the opening of the breeding box body 1, and the auxiliary frame 3 is in close contact with the inner wall of the breeding box body 1.

[0024] The edge of the sealing cover 2 is fixedly connected with a sealing block 6, the sealing block 6 is a component made of rubber material, the inside of the sealing block 6 is a hollow structure, the inner wall of the sealing block 6 is fixedly connected with a rubber elastic column 7, the rubber elastic column 7 is provided in multiple groups and is evenly arranged about the inner wall of the sealing block 6.

[0025] Specifically, the leech seedlings are stored in the cavity of the breeding box body 1. When the leech seedlings climb up from the inner wall of the breeding box body 1, the auxiliary frame 3 and the partition net body 4 are blocked, and the auxiliary frame 3 can be pressed down. The auxiliary frame 3 moves downward along the inner wall of the breeding box body 1, drives the inner connecting rod 51 to press down the movable block 53, and the movable block 53 is pressed tightly against the return spring 56. Since the auxiliary frame 3 is attached to the inner wall of the breeding box body 1, the auxiliary frame 3 can push the climbing leech seedlings down. Then, the auxiliary frame 3 is released, and the return spring 56 drives the inner connecting rod 51 to lift the auxiliary frame 3, so that the auxiliary frame 3 returns to the original position. The operation is convenient, and the problem that the leech seedlings easily climb up the inner wall of the container, escape from the gap between the breeding box and the sealing cover, cause the loss of seedlings, and increase the breeding cost is solved.

[0026] When the sealing cover 2 is closed, the inner wall of the breeding box body 1 extrudes the sealing block 6, the outer wall of the sealing block 6 is deformed under pressure, thereby extruding the rubber elastic column 7 inside the sealing block 6. Therefore, through the elasticity of the sealing block 6 and the reaction force of the rubber elastic column 7, the deformed part of the sealing block 6 tightly tops the inner wall of the breeding box body 1, improving the sealing performance.

[0027] In summary: When the leech seedlings climb up from the inner wall of the breeding box body 1, the auxiliary frame 3 and the partition net body 4 are blocked, and the auxiliary frame 3 can be pressed down. The auxiliary frame 3 moves downward along the inner wall of the breeding box body 1, drives the inner connecting rod 51 to press down the movable block 53, and the movable block 53 is pressed tightly against the return spring 56. Since the auxiliary frame 3 is attached to the inner wall of the breeding box body 1, the auxiliary frame 3 can push the climbing leech seedlings down. Then, the auxiliary frame 3 is released, and the return spring 56 drives the inner connecting rod 51 to lift the auxiliary frame 3, so that the auxiliary frame 3 returns to the original position. When the sealing cover 2 is closed, the inner wall of the breeding box body 1 extrudes the sealing block 6, the outer wall of the sealing block 6 is deformed under pressure, thereby extruding the rubber elastic column 7 inside the sealing block 6. Therefore, through the elasticity of the sealing block 6 and the reaction force of the rubber elastic column 7, the deformed part of the sealing block 6 tightly tops the inner wall of the breeding box body 1.
