Description

Technical Field

[0001] The utility model relates to the technical field of fishing appliances, in particular to an expandable three-legged support folding bridging for fishing. Background Art

[0002] With the improvement of living standards, fishing, while being a fishing method, has gradually developed into a recreational and mood-cultivating sports activity full of fun.

[0003] Generally speaking, suitable fishing locations are mostly located in rugged terrains such as by lakes and rivers. In order to facilitate anglers to place fishing rods stably and safely, fishing platforms have emerged. However, in the prior art, when the fishing platform is put into use, the following situations exist: In order to enable the fishing platform to be set up stably in the water, the fishing platform is usually set in the water at a certain distance from the shore, or due to the rising water level in this water area, the fishing platform is farther away from the shore, which causes the trouble for anglers that they need to wade through the water to land on the fishing platform, which is very inconvenient, and the underwater objects to step on are uneven, posing certain dangers. Therefore, how to solve the problems that anglers need to wade through the water and are in danger when landing on the fishing platform in the prior art has become an important technical problem to be solved by those skilled in the art.

[0004] The utility model patent with the publication number CN216108019U discloses a fishing platform auxiliary bridging. The fishing platform auxiliary bridging includes a bridge pier and a hanging structure. Among them, the bridge pier includes several spliced bridge plates, and the hanging structure is arranged on the side of the bridge pier, and the hanging structure can be hooked to the fishing platform. With such a setting, one side of the fishing platform auxiliary bridging is hooked to the fishing platform, and the opposite side is placed on the shore or supported by other objects. Anglers can smoothly reach the fishing platform by stepping on the bridge pier. Even when the distance between the fishing platform and the shore is far and there is water, it will not affect the normal progress of the fishing plan, and there is no need to wade through the water, which is safe and reliable, and solves the problems that anglers need to wade through the water and are in danger when landing on the fishing platform in the prior art.

[0005] However, the fishing platform is set in the water area. Although there is no need to wade through the water to pass after the fishing platform and the auxiliary bridging are set up, this patent requires the fishing platform to be set up first and then the auxiliary bridging to be laid. The processes of setting up and dismantling the fishing platform and the auxiliary bridging still need to wade through the water to be successfully completed. Moreover, the objects at the bottom of the water area are uneven, the spacing is relatively narrow, and the four-legged support legs are difficult to adjust to fully contact with the objects at the bottom of the water area, resulting in the instability of the auxiliary bridging. At the same time, the auxiliary bridging is temporarily set up and needs to be dismantled after fishing. The existing design is large in volume and is not convenient for disassembly and storage.

[0006] Therefore, there is an urgent need to design an expandable three-legged support folding bridging for fishing. Summary of the Invention
