Description

Technical Field

[0001] This utility model relates to the field of fish control equipment technology, specifically to a fish control device. Background Technology

[0002] Fishing is becoming an increasingly popular leisure activity. After a fish is hooked, removing it from the hook is usually done manually, requiring one hand to hold the fish's body and the other to remove the hook. At this time, the fish's struggles often result in cuts to the hand from its fins or spines. To address this, fish control devices were invented. However, existing fish control devices are prone to being stretched open by the fish they are holding when opened to a large angle, leading to failure in controlling the fish. Therefore, this shortcoming needs to be addressed promptly. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fish control device.

[0004] The technical solution of this utility model is as follows: This utility model provides a fish control device, including a mounting base. A push rod assembly is slidably disposed in the mounting base along its length. A gripper assembly is disposed on the front side of the mounting base via a first pivot. The gripper assembly includes a first gripper and a second gripper rotatably connected via the first pivot. The portion of the first gripper and the second gripper away from the gripping end is a control arm. A third pivot is mounted on the front end of the push rod assembly corresponding to the two control arms. The control arm has an elongated hole that mates with the third pivot. The third pivot extends into the corresponding elongated hole. The mounting base is provided with guide structures corresponding to the two third pivots. When the third pivot slides towards the front end of the guide structure, it pushes the corresponding control arm outward. The elongated hole has an opening surface near the outer side and a closing surface near the inner side. The closing surface includes at least a first closing surface near the free end of the control arm and a second closing surface near the first pivot. The acute angle A between the second closing surface and the guide structure on the same side is smaller than the acute angle B between the first closing surface and the guide structure on the same side.

[0005] Furthermore, the guide structure includes a second guide groove on the mounting base corresponding to the third pivot, and the third pivot slides in conjunction with the corresponding second guide groove.

[0006] Furthermore, the distance between the front ends of the two second guide grooves is greater than the distance between the rear ends.

[0007] Furthermore, the push rod assembly includes a first push rod and a second push rod corresponding to the first and second grippers. The front ends of the first and second push rods are rotatably connected to one end of the corresponding connecting rod via a second pivot, and the other end of the connecting rod is equipped with a third pivot.

[0008] Furthermore, both the first push rod and the second push rod are slidably installed with the mounting base through the first guide groove assembly.

[0009] Furthermore, the mounting base includes a first mounting base and a second mounting base disposed opposite to each other, and a first guide groove is formed on the inner side of the first mounting base and the second mounting base opposite to each other.

[0010] Furthermore, the first gripper and the second gripper are constrained between the opposing inner surfaces of the first mounting base and the second mounting base, and both sides of the control arm are in contact with the opposing inner surfaces of the first mounting base and the second mounting base.

[0011] Furthermore, an elastic element is provided on the rear side of the mounting base. One end of the elastic element is a fixed end, and the other end of the elastic element is a free end. The free end of the elastic element is connected to the push rod assembly.

[0012] Furthermore, the elastic element is a spring.

[0013] The beneficial effects achieved by this utility model are as follows: This invention clamps the fish using the clamping ends of the first and second jaws. At this time, the third pivot is in contact with the corresponding second closed surface. When the fish is clamped, the fish exerts a reaction force F1 on the clamping end. The second closed surface then presses against the corresponding third pivot. The reaction force F1 causes the first and second jaws to tend to open again. The angle design of the second closed surface allows the first and second jaws to maintain a more stable clamping state, especially when the first and second jaws are in a large-open clamping state.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0018] like Figures 1-5 As shown, this utility model provides a fish control device, including a mounting base. A push rod assembly 1 is slidably disposed within the mounting base along its length. A gripper assembly 2 is disposed on the front side of the mounting base. The gripper assembly 2 includes a first gripper 201 and a second gripper 202 that are cross-hinged. The push rod assembly 1 includes a first push rod 101 and a second push rod 102 corresponding to the first gripper 201 and the second gripper 202. An elastic element 3 is disposed on the rear side of the mounting base. The elastic element 3 is preferably a spring. One end of the elastic element is a fixed end, and the other end of the elastic element is a free end. The free end of the elastic element is connected to the push rod assembly. When the push rod assembly is pushed, the elastic element stores energy, and the first push rod 101 and the second push rod 102 individually control the opening of the corresponding first gripper 201 and second gripper 202. When the push rod assembly is released, the elastic element has a tendency to drive the push rod assembly to reset and cause the first gripper 201 and the second gripper 202 to close together.

[0019] The first push rod and the second push rod of the push rod assembly are slidably installed with the mounting base through the first guide groove group 4. This design can ensure the installation stability of the first push rod and the second push rod. The mounting base includes a first mounting base 5 and a second mounting base 6 arranged opposite to each other. The first guide groove group is opened on the inner side of the first mounting base and the second mounting base opposite to each other.

[0020] The first gripper 201 and the second gripper 202 are arranged in a cross configuration, and the intersection is rotatably connected by the first pivot 7. The portion of the first gripper 201 and the second gripper 202 away from the gripping end is the control arm. The front end of the first push rod and the front end of the second push rod are connected to the corresponding control arm via a connecting rod 8, which is also part of the push rod assembly. The first gripper 201 and the second gripper 202 are constrained between the opposing inner surfaces of the first mounting base 5 and the second mounting base 6. Both sides of the control arm are in contact with the opposing inner surfaces of the first mounting base 5 and the second mounting base 6, which can improve the stability of the structure by preventing the first gripper 201 and the second gripper 202 from swaying to the side when rotating.

[0021] The front ends of the first push rod and the second push rod are rotatably connected to one end of the corresponding connecting rod 8 via the second pivot 9. The other end of the connecting rod 8 is equipped with a third pivot 10. The control arm has an elongated hole 11 that mates with the third pivot. The third pivot extends into the corresponding elongated hole 11. The mounting base is provided with guide structures for the two third pivots respectively. The guide structures are the second guide grooves 12 opened by the mounting base for the two third pivots respectively. The third pivot 11 and the second guide groove 12 are slidably engaged. The distance between the front ends of the two second guide grooves is greater than the distance between the rear ends. The second guide grooves guide the sliding of the third pivot. When the third pivot slides towards the front end of the second guide groove, it pushes the corresponding control arm outward, thereby opening the first gripper 201 and the second gripper 202. Conversely, it controls the first gripper 201 and the second gripper 202 to close.

[0022] The elongated hole 11 has an outwardly extending surface 13 and an inwardly closing surface 14. The closing surface includes at least a first closing surface 141 near the free end of the control arm and a second closing surface 142 near the first pivot. The acute angle A between the second closing surface 142 and the second guide groove 12 on the same side is smaller than the acute angle B between the first closing surface 141 and the second guide groove 12 on the same side. When the third pivot slides along the front end of the second guide groove, it cooperates with the extending surface 13 to extend the corresponding control arm outward. When the first gripper 201 and the second gripper 202 are open, the third pivot 10 is located on one side of the corresponding second closing surface 142. Figure 3As shown, at this time, the elastic element has the tendency to drive the push rod assembly to reset and close the first gripper 201 and the second gripper 202 together, thereby clamping the fish through the clamping ends of the first gripper 201 and the second gripper 202. At this time, the third pivot is in contact with the corresponding second closing surface 142. When the fish is clamped, the fish exerts a reaction force F1 on the clamping end. At this time, the second closing surface presses against the corresponding third pivot. The reaction force F makes the first gripper 201 and the second gripper 202 tend to be opened again. Since the second closing surface 142 has an acute angle A with the second guide groove 12 on the same side, if the reaction force F1 is large enough, the third pivot will be pushed to the front end of the corresponding second guide groove. At this time, the first gripper 201 and the second gripper 202 are opened. Since the acute angle A between the second closing surface 142 and the second guide groove 12 on the same side is smaller than the acute angle B between the first closing surface 141 and the second guide groove 12 on the same side, the force F2 applied by the second closing surface 142 to the third pivot is... The obtuse angle C between the direction and the second guide groove 12 is closer to perpendicular, making it less likely to push the third pivot towards the front end of the second guide groove. In other words, the third pivot can better prevent the first gripper 201 and the second gripper 202 from being pried open. The angle design of the second closing surface 142 can better maintain the clamping state of the first gripper 201 and the second gripper 202 more stably. In particular, the clamping state of the first gripper 201 and the second gripper 202 with a large opening is more stable. This is because without the angle design of the second closing surface 142, that is, when the closing surface 14 is in a straight state, the reaction force F1 can more easily pry the first gripper 201 and the second gripper 202 open when the first gripper 201 and the second gripper 202 are in a large opening clamping state. Therefore, the direction of F2 is less perpendicular to the obtuse angle C of the second guide groove 12. The above conclusion can be easily drawn through mechanical disassembly analysis, and will not be elaborated further here.

[0023] The working principle is as follows: the fish is clamped by the gripping ends of the first and second jaws. At this time, the third pivot is in contact with the corresponding second closed surface. When the fish is clamped, the fish exerts a reaction force F1 on the gripping end. At this time, the second closed surface presses against the corresponding third pivot. The reaction force F1 makes the first and second jaws tend to be opened again. The angle design of the second closed surface can better maintain the clamping state of the first and second jaws more stably, especially when the first and second jaws are in a large-open clamping state.

[0024] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
