Problems solved by technology

The existing ground nails are made of wood or plastic, and it is not easy to insert deep into the ground. If there is a strong wind, the ground nails will not be fixed firmly, and the tent will be easily blown away by the wind, which poses a safety hazard. If the ground nails are firmly fixed, put them away. When using tents, the ground nails are not easy to pull out, and a lot of force is required, which consumes energy and time

Abstract

The invention provides an easy-to-pull ground nail. The ground nail comprises a ground nail body and a nail head; an air outlet is formed in the upper part of the ground nail body, and an air blockingcover is arranged at the air outlet; a movable groove is formed in the ground nail body; an air inlet is formed in the upper surface of the ground nail body; a rotary cavity is formed between the bottom surface of the ground nail body and the upper surface of the nail head; a rotating rod is arranged in the ground nail body; a baffle I is arranged in the ground nail body; an air valve I and an air valve II are arranged between the rotating rod and the inner wall of the ground nail body; the upper part of the air valve I is conical, and an air hole is formed in the center of the air valve I; an air blocking bead is arranged in the air valve I, a spring is arranged below the air blocking bead, a butting plate is arranged in the movable groove, and a pressing cavity is formed between a baffle II and the inner wall of the ground nail. After the middle rotating rod rotates, the crescent baffles extend out, so that the ground nail is firmly fixed. The butting plate ascends and descends dueto the air pressure control, the ground nail is easier to pull out, the operation is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a ground nail that is easy to pull out. Background technique [0002] Generally speaking, camping in the wild requires setting up a tent, and the ropes that fix the tent are tied to the ground nails. The existing ground nails are made of wood or plastic, and it is not easy to insert deep into the ground. If there is a strong wind, the ground nails will not be fixed firmly, and the tent will be easily blown away by the wind, which poses a safety hazard. If the ground nails are firmly fixed, put them away. When using a tent, the ground nails are not easy to pull out, which requires a lot of force, energy and time. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ground nail that is easy to pull out. [0004] The technical solution adopted by the present invention to solve the technical problem is: a ground nail tha...
