Description

Technical Field

[0001] The utility model relates to the technical field of iron sheets and iron nails, in particular to an anti-loosening fixing iron sheet and iron nail. Background Art

[0002] A nail refers to a pointed piece of hard metal used to fix wood and other objects. Cast iron nails are also called iron nails. They are hammered into objects with a hammer. Recently, electric nail guns and gas nail guns have also appeared. The reason why iron nails can stabilize objects is that they can hook on them by their own deformation and rely on friction. Anti-loosening iron nails are one of the most common things in decoration.

[0003] The existing anti-loosening iron nails are usually used together with iron sheets during use, but the friction between the vertical nail body, the smooth iron sheet and the object is not large enough, so the iron nails are easily fallen off the objects, resulting in loose connection of the objects. Utility Model Content

[0004] The utility model aims to solve the problem that the existing anti-loosening iron nails are usually used together with iron sheets during use, but the friction between the vertical nail body, the smooth iron sheet and the object is not large enough, so the iron nail is easy to fall off the object, resulting in the loose connection of the object, and an anti-loosening fixing iron sheet iron nail is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An anti-loosening fixing iron sheet and iron nail, comprising:

[0007] A nail cap, a movable nail rod is installed on one side of the nail cap, and a fixed nail rod is arranged on the outside of the movable nail rod, a connecting groove is opened inside the fixed nail rod, and a barb is installed on the outside of the fixed nail rod, a threaded portion is arranged on the surface of the movable nail rod, and an iron sheet ring is movably connected to the outside of the movable nail rod, a fixing groove is opened inside the iron sheet ring, and a hook is installed on the outside of the iron sheet ring, and a fixing sleeve is connected to one side of the iron sheet ring and the outside of the movable nail rod.

[0008] Preferably, a detachable structure is formed between the iron sheet ring and the movable nail rod through a fixing sleeve and a fixing groove, and the inner wall of the fixing groove is in contact with the outer wall of the movable nail rod.

[0009] Preferably, the movable nail rod and the fixed nail rod form a fixing structure through a threaded portion and a connecting groove, and the inner wall of the connecting groove is a threaded structure.

[0010] Preferably, the hooks are symmetrical about the center point of the iron sheet ring.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model is provided with a nail cap, a fixing sleeve, a movable nail rod, barbs, a fixing nail rod, an iron sheet ring and a hook. The hook increases the fixing points and fixing area between the iron sheet ring and the object to be fixed. The barbs increase the reverse force area between the iron nail and the object, so that the fixing nail rod can be firmly combined with the object, and the iron nail is not easy to loosen after being nailed into the object, thereby making it difficult for the iron nail as a whole to be separated from the object to be fixed.

[0013] 2. In the utility model, a nail cap, a movable nail rod, a fixed nail rod, a connecting groove and a threaded portion are provided. By operating the nail cap, the movable nail rod and the threaded portion can be conveniently driven to rotate, so that the length of the entire nail rod can be easily adjusted, so that the iron nail can adapt to a variety of objects to be fastened with different thicknesses, and has high practicality.

[0023] Reference Figure 1-3 A kind of anti-loosening fixed iron sheet iron nail, including a nail cap 1, a movable nail rod 2 is installed on one side of the nail cap 1, and a fixed nail rod 3 is arranged on the outside of the movable nail rod 2, the movable nail rod 2 and the fixed nail rod 3 form a fixed structure through a threaded portion 8 and a connecting groove 9, and the inner wall of the connecting groove 9 is a threaded structure, the movable nail rod 2 is manually operated, the movable nail rod 2 drives the threaded portion 8 to rotate, and the threaded portion 8 will rotate into the connecting groove 9, so that it is convenient to complete the fixing work of the movable nail rod 2, the inside of the fixed nail rod 3 is provided with a connecting groove 9, and the outside of the fixed nail rod 3 is installed with a barb 4, the surface of the movable nail rod 2 is provided with a threaded portion 8, and the outside of the movable nail rod 2 is movably connected with an iron sheet ring 5, and the iron sheet ring 5 and the movable nail rod 2 are connected. A detachable structure is formed by a fixing sleeve 7 and a fixing groove 10, and the inner wall of the fixing groove 10 contacts the outer wall of the movable nail rod 2. The fixing sleeve 7 is manually operated and moved to the outside of the movable nail rod 2, so that the restriction of the iron sheet ring 5 can be released. The iron sheet ring 5 can then be moved to the outside of the movable nail rod 2 through the fixing groove 10, so that the disassembly of the iron sheet ring 5 is convenient. A fixing groove 10 is provided inside the iron sheet ring 5, and a hook 6 is installed outside the iron sheet ring 5. The hook 6 is symmetrical about the center point of the iron sheet ring 5.
