Description

A kind of fiber nail

Technical field

The utility model is related to screw technique field, specially a kind of fiber nail.

Background technology

Fiber nail is a kind of common fastener in current daily life, for component and component to be fixedly connected on one Rise, when fiber nail is used by the operator, it is necessary to using can only single use screwdriver it could be carried out it is elastic or fastening, If temporarily without this tool but must to fiber nail carry out it is elastic or fastening when, this just causes our work Influence, in addition, fiber nail can only single use screwdriver promoted, often will appear nut groove quilt during propulsion The situation of destruction, groove are destroyed, and fiber nail is just dropped, and cause to waste.

Utility model content

The purpose of this utility model is to provide a kind of fiber nail, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides following technical solution：A kind of fiber nail, including nail rod, the head of a nail and Ailhead is uniformly provided with main thread in the nail rod, is interrupted equidistant being fixed with barb, and one end of nail rod is equipped with nail on main thread Head is uniformly provided with the incremental start screw threads of volume on ailhead, and start screw threads are fixedly connected with main thread, and the nail rod is far from ailhead One end be fixed with the head of a nail, the junction of the head of a nail and nail rod is equipped with rib, and in the nail rod between the head of a nail and main thread top Equipped with milling muscle, the diameter of milling muscle is more than the diameter of nail rod, and the center position at the top of the head of a nail is welded with block, the top of block Portion offers crisscross grooves.

Preferably, the ailhead is conical structure.

Preferably, the block is regular hexagonal prism structure, and the height of block is 2-4mm.

Preferably, the flight pitch of the start screw threads is less than the flight pitch of main thread.

Preferably, the barb is triangular structure, and barb zenith directions are identical with main thread direction.

Compared with prior art, the beneficial effects of the utility model are：

(1) fiber nail at the top of the head of a nail by setting the block of regular hexagonal prism structure, and opened up at the top of block There are crisscross grooves so that fiber nail is easy to use there are a variety of modes of operation when in use, improves service efficiency.

(2) fiber nail on ailhead by setting the start screw threads smaller than main thread flight pitch so that the fiber nail It is more convenient in starting to hammer into, it is time saving and energy saving, further improve service efficiency.

(3) fiber nail is not being influenced by the barb for setting zenith directions identical with main thread direction on main thread Under the premise of hammering into, fiber nail is avoided to extract, effectively promote connectivity robustness.

(4) fiber nail extends through external screw thread by being equipped with milling muscle in the nail rod between the head of a nail and main thread top The drilling of generation so as to reduce the friction between workpiece and the unthreaded portion of fiber nail, reduces the stress in workpiece.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

- 3 are please referred to Fig.1, a kind of embodiment provided by the utility model：A kind of fiber nail, including nail rod 5, the head of a nail 2 and nail First 7, be uniformly provided with main thread 6 in nail rod 5, be interrupted on main thread 6 it is equidistant be fixed with barb 10, barb 10 is triangle knot Structure, and 10 zenith directions of barb are identical with 6 direction of main thread, under the premise of not influencing to hammer into, fiber nail avoided to extract, effectively Promotion connectivity robustness, and one end of nail rod 5 is equipped with ailhead 7, and ailhead 7 is conical structure, is uniformly provided with volume on ailhead 7 Incremental start screw threads 8, start screw threads 8 are fixedly connected with main thread 6, and the flight pitch of start screw threads 8 is less than the spiral shell of main thread 6 Line spacing, since the flight pitch between the start screw threads 8 that are set on ailhead 7 is less than the flight pitch of main thread 6 in nail rod 5, So that the resistance smaller when entering workpiece of ailhead 7, facilitates starting to hammer into, easy to use, raising hammers into efficiency, and nail rod 5 is far from nail First 7 one end is fixed with the head of a nail 2, and the head of a nail 2 and the junction of nail rod 5 are equipped with rib 3, and between 6 top of the head of a nail 2 and main thread Nail rod 5 be equipped with milling muscle 4, the diameter of milling muscle 4 is more than the diameter of nail rod 5, and milling muscle 4 extends through the workpiece of the generation of external screw thread 6 Drilling, more convenient to hammer into so as to reduce the friction between 5 unthreaded portion of workpiece and nail rod, the center at 2 top of the head of a nail Place is welded with block 1, and block 1 is regular hexagonal prism structure, and the height of block 1 is 2-4mm, and the top of block 1 offers cross Groove 9 so that fiber nail is easy to use there are a variety of modes of operation when in use, improves service efficiency.

Operation principle：In use, according to practical operation needs, select fiber nail to be driven to hammer by block 1 using handle Workpiece or workpiece is hammered by the drive of crisscross grooves 9 using screwdriver, due between the start screw threads 8 that are set on ailhead 7 Flight pitch is less than the flight pitch of main thread 6 in nail rod 5 so that the resistance smaller when entering workpiece of ailhead 7 facilitates starting to follow closely Enter, it is easy to use, since the nail rod 5 between 6 top of the head of a nail 2 and main thread is equipped with milling muscle 4, extends through external screw thread 6 and generate Workpiece boring, it is more convenient to hammer into so as to reduce the friction between 5 unthreaded portion of workpiece and nail rod, after hammering into, due to master The barb 10 for setting zenith directions identical with 6 direction of main thread on screw thread 6, avoids fiber nail from extracting, and promotes connectivity robustness.
