Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] The invention provides an anti-loosening nail, which is characterized in that: it includes a nail body 1, and a plurality of barbs 2 are evenly distributed on the side surface of the nail body 1; After being nailed in, the barb 2 will hook the object firmly so that it is not easy to withdraw.

[0013] A cavity 3 is arranged in the middle of the nail body 1, and a nail needle 4 with a length smaller than the length of the cavity and a wedge-shaped head is arranged in the cavity 3, and transverse through holes are arranged on both sides of the head of the nail needle 4. A movable block 6 is arranged in the hole 5 and the through hole 5 .

[0014] One end of the movable block 6 is in contact with the wedge surface of the head of the nail 4 , and the other end is flush with the surface of the nail body 1 .

[0015] After the nail is driven...

Abstract

The invention provides an anti-loose nail which comprises a nail body. A plurality of barbs are distributed on the side surface of the nail body. A cavity is formed in the middle of the nail body; a nail needle with the length smaller than that of the cavity is arranged in the cavity, and the head of the nail needle is in a wedge shape; transverse through holes are formed in the two sides of the head of the nail needle; movable blocks are arranged in the through holes; one end of each movable block is in contact with the wedge face of the head of the nail needle, and the other end of each movable block is flushed with the surface of the nail body. The anti-loose nail has the beneficial effect that the barbs on the surface of the nail body can fixedly hook an object without easy retracting; after the nail is driven into the object, the nail needle is pushed forwards, the wedge face on the head of the nail needle pushes the movable blocks out of the two sides, and the movable blocks transversely protrude out of the surface of the nail body; the nail body is more firmly embedded into the nailed object, and the phenomenon that due to shaking or stressing, the nail loosens and drops is avoided. The anti-loose nail has the advantages of being simple in structure, reasonable in design, firm in fixation, good in safety and the like.

Description

technical field [0001] The invention belongs to the field of daily hardware devices, in particular to an anti-loosening nail. Background technique [0002] In the prior art, the nail shank of the nail is smooth, and it is easy to be loosened and withdrawn by the shaking or vibration of the object after being nailed into the object. There are technical problems such as unreasonable structural design, unstable fixation, time-consuming and laborious adjustment, low work efficiency, and poor safety performance. Contents of the invention [0003] The object of the present invention is to provide a nail with simple structure, convenient operation and high work efficiency, which is especially suitable for fixing objects in daily life. [0004] The technical solution of the present invention is to provide an anti-loosening nail, which is characterized in that: it includes a nail body, a plurality of barbs are evenly distributed on the side surface of the nail body; a cavity is ar...
