Description

Technical Field

[0001] The utility model belongs to the technical field of trapping equipment, and in particular relates to a frog catcher. Background Art

[0002] When sampling and investigating frogs, it is necessary to capture frogs first. Traditional manual capture has been gradually replaced by some frog catchers due to many safety issues and high labor intensity. For example, the Chinese patent No. 201310257812.X specifically discloses that the frog catcher includes a capture cavity and an upper cover. A fixing belt is connected between the middle of the capture cavity and the middle of the upper cover. A light tube is provided in the middle of the inner side of the upper cover. An opening is provided at the top of the capture cavity. Two notches are divided by a fixing rod, etc., and movable covers are evenly arranged in the notches. The movable covers are movably connected to the side walls of the capture cavity and the fixing rods through elastic connection components. A door is provided on the front side of the capture cavity. A solar panel is embedded in the upper cover. A pull ring is installed on the front side of the upper cover. The frog catcher has many parts and a relatively complex structure. Therefore, it is very necessary to design a frog catcher with a simple structure and convenient use. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of the design of the utility model is to provide a frog catcher with few parts and simple structure, which is specifically achieved through the following technical solutions:

[0004] The frog catcher comprises a capturing cavity and a cover assembly arranged at the upper open end of the capturing cavity, the cover assembly comprising a mesh cover plate and a hole cover plate, one end of the hole cover plate is welded to the inner edge of the mesh cover plate, and the mesh cover plate and the hole cover plate are arranged at 90 degrees; the capturing cavity is a trapezoidal structure with an upper open end, and is composed of a bottom plate, a front panel, a rear panel and side panels, the upper surface of the rear panel is connected to the bottom of the cover assembly by a hinge, magnets are installed on the inner sides of the front panel, the rear panel and the hole cover plate, and the magnet installed on the hole cover plate is in a balanced state with the magnet installed on the front panel, and the hinge is opened, and the hole cover plate covers the upper opening of the capturing cavity.

[0014] The utility model is further described below in conjunction with the accompanying drawings in order to better understand the technical solution.

[0015] like Figure 1-2 As shown, the frog catcher of the utility model comprises a capturing cavity 1 and a cover assembly arranged at the upper open end of the capturing cavity 1, the cover assembly comprises a mesh cover plate 2 and a hole cover plate 3, one end of the hole cover plate 2 is welded to the inner edge of the mesh cover plate 3, and the mesh cover plate 2 and the hole cover plate 3 are arranged at 90°; the capturing cavity 1 is a trapezoidal structure with an upper open end, the outer edge of the hole cover plate 2 coincides with the inner edge of the upper opening of the capturing cavity 1, and the outer edge of the mesh cover plate 2 is not smaller than the outer edge of the upper opening of the capturing cavity 1.

[0016] The trapezoidal structure of the capture cavity 1 is convenient for improving stability when it is buried in the soil and reducing the impact of the environment on the frog capture efficiency. It is specifically composed of a base plate 4, a front panel 5, a rear panel 6 and a side panel 7. The upper surface of the rear panel 6 is connected to the bottom of the cover assembly through a hinge. The inner sides of the front panel 5, the rear panel 6 and the hole cover plate 3 are all equipped with cube-shaped magnets 8, and the magnets 8 installed on the hole cover plate 3 are in a balanced state with the magnets 8 installed on the front panel 5. When the hinge is opened, the hole cover plate 3 covers the upper end opening of the capture cavity 1. The magnet 8 on the inner wall of the hole cover plate 3 is installed at the end away from the hinge, and the distance from the upper surface of the magnet 8 installed on the rear panel 6 to the top of the rear panel 6 is equal to the farthest distance from the magnet 8 installed on the hole cover plate 3 to the top of the rear panel 6. This arrangement facilitates the rotation of the hole cover plate 3 into the capture cavity 1 when the mesh cover plate 2 covers the upper end opening of the capture cavity 1, and the magnet 8 on the hole cover plate 3 is firmly adsorbed with the magnet 8 on the rear panel 6. The installation positions of the magnets 8 on the front panel 5 and the hole cover plate 3 make the lower surface of the hole cover plate 3 and the side end surface of the front panel 5 located in the same plane.

[0017] The specific dimensions of the frog catcher of the utility model can be selected as follows: the length of the mesh cover plate 2 is 30 cm and the width is 18 cm; the length of the hole cover plate 3 is 25 cm and the width is 18 cm. In this way, when the magnet 8 on the hole cover plate 3 and the magnet 8 on the rear panel 6 are attracted to each other, the mesh cover plate 2 can cover the upper end opening of the capture cavity 1 to prevent the frog falling into the capture cavity 1 from escaping.

[0018] The distance between the magnet 8 fixedly mounted below the hole cover plate 3 and the connection between the mesh cover plate 2 and the hole cover plate 3 is 20 cm, the length of the bottom plate 4 is 60 cm, the width is 20 cm, and the magnet 8 is a cube with an edge length of 2 cm; the length of the rear panel 6 is 40 cm, the width is 20 cm, the magnet 8 fixedly mounted on the rear panel 6 is located on the inner side of the capture cavity 1, and the distance from the magnet 8 to the top of the rear panel 6 is 22 cm. The magnet 8 is fixedly mounted on the lower surface of the front panel 5. When the magnet 8 mounted on the hole cover plate 3 and the magnet 8 of the front panel 5 form a balanced state, the lower surface of the hole cover plate 3 and the side end surface of the front panel 5 are located in the same plane, and the length of the side end surface of the front panel 5 is 25 cm, and the width is 1 cm. With such arrangement, the magnet 8 installed on the hole surface cover plate 3 and the magnet 8 installed on the front panel 5 form a balanced state, and the lower surface of the hole surface cover plate 3 and the side end surface of the front panel 5 are located in the same plane. When a frog jumps onto the hole surface cover plate 3, the balanced state formed by the magnet 8 on the hole surface cover plate 3 and the magnet 8 on the front panel 5 is broken, and the hole surface cover plate 3 is flipped downward under the action of gravity, and the frog falls into the capture cavity 1, and the magnet 8 on the hole surface cover plate 3 and the magnet 8 on the rear panel 6 attract each other, the cover body assembly flips downward, and the mesh cover plate 2 covers the upper end opening of the capture cavity 1.

[0019] When in use, the capture cavity 1 is partially buried in the soil, the bait is placed in the capture cavity 1, the mesh cover plate 2 is pulled to drive the hole cover plate 3, the magnet 8 installed on the hole cover plate 3 and the magnet 8 installed on the front panel 5 form a balanced state, the hinge is in an open state, the cover body is suspended, and the hole cover plate 3 covers the upper end opening of the capture cavity 1 to complete the installation. When the frog smells the smell of the bait and jumps on the hole cover plate 3, the balance between the hole cover plate 3 and the front panel 5 is destroyed. Under the action of gravity, the hole cover plate 3 flips down, and the frog falls into the capture cavity 1. The magnet 8 on the hole cover plate 3 and the magnet 8 on the rear panel 6 attract each other, the cover assembly flips down, the hinge is in a closed state, and the mesh cover plate 2 covers the upper end opening of the capture cavity 1 to complete the capture. When taking the frog, the device is taken out of the soil and inverted, and the mesh cover plate 2 is pulled to drive the hole cover plate 3 to separate the magnet of the hole cover plate 3 from the magnet 8 of the rear panel 6, and the frog is taken out. The device can achieve this by changing the magnetic force of the magnet according to the size of the frog to be captured.
