Description

A kind of Novel nail

Technical field

Instrument manufacturing field is the utility model is related to, the Novel nail fixed particularly for plank, woodenware, wall.

Background technology

With the development of modern industry, the use of nail is very universal, and the function of nail also becomes more diverse.One A little specially designed nails, have special purposes and function.

The axial restraint ability of common nail is very weak, because its all carrys out limit value movement by sliding friction, hammers into rear past Exited toward easily loosening, the object for causing to be fixed comes off.After common nails hammer into, there is no any latch at its rivet nut position, Not only nail is easily slided along axis, and nailed object is also easy to rotate.Although thering are some nail designs to have hangnail on the market at present, Prevent nail from having exited certain effect, but it prevents that the ability of axial rotation is limited.The expansion bolt being widely used at present (screw), its structure is relative complex, and using preceding need with electric drill bore a sizeable hole, bolt is then filled in hole Simultaneously the nut of bolt is tightened and could fixed in hole.

The function of common nails is relatively simple at present and has many limitations, and expansion bolt (screw) is complicated, It is inconvenient for use, the embedded fixation on wall and ground is only used for, the function for not possessing nail.Therefore, exploitation is a kind of simple in structure, Easy to use, nail vdiverse in function is necessary.

A kind of Novel nail of inventor's design, not only possesses anti-retrogression, anti-loosening, anti-rotation that common nails do not possess Function, but also have the function of expansion bolt and rivet concurrently, its is simple in structure, easy to use, can be widely used for wooden utensil, Glued board bind and the embedded fixation on metope and ground.

Utility model content

The utility model nail mainly solves the shortcomings that existing common nails are easily loosened, fallen back and does not possess embedded solid Fixed and riveted technical limitation, it is as follows that its shape, structure and each component form taken technical measures：

A kind of Novel nail (attached drawing 9), it is characterised in that：Rivet nut including the hexagonal head of a nail (2), tool internal thread cavity (3), interior latch (1), two latches (4), the hexagonal head of a nail are connected with having the cavity rivet nut of internal thread, the interior latch It is nested in the rivet nut of tool internal thread cavity, described two latches are located at nail lower part.

The hexagon head of a nail (2) and the rivet nut (3) for having thread cavity are connected and one are made, different from current nail, it Shape be hexagon, the inside for having the rivet nut of thread cavity is designed for cavity, for being inserted into latch, the top half tool of cavity There is internal thread, behind the sub- bottom of latch knock-in tack, the cavity for having threaded portion reveals, and facilitates precession screw or bolt, makes Obtain the nail and possess the identical function of common expansion bolt.In the close nail afterbody of rivet nut, there are a square hole, this hole Hole provides laterally movable space for two latches, and nailed object is caught in by this hole after latch stress.

There are cross one another 90 degree of inclined-planes in the lower end of interior latch (1), and there is the beveling of mutual 90 degree of intersections in the lower end of interior latch Face, scarf of the scarf respectively with two latch one end is connected, and when hammering into, interior latch active force directed downwardly is delivered to latch On, latch is blocked into such as nailed object along rivet nut hole towards extrapolation.

One end scarf of two latches (4) is connected with the scarf of interior latch, and the other end is cut into two one big up and down One small bevel, greatly downward, it is small upward.The square hole in the rivet nut of tool internal thread cavity is overlayed using preceding latch Hole, after use, two horizontal latches are released and are caught in nailed object by interior latch along hole.

Helpfulness effect：The utility model, can be widely used for wooden utensil, glued board bind and metope and ground It is embedded to fix, not only possess anti-retrogression, anti-loosening, anti-rotation function that common nails do not possess, but also have expanding screw concurrently The fixed function of bolt and rivet, its is simple in structure, easy to use, can be as the replacement solution party of expansion bolt under Part load Case.

【Embodiment】

The principle and feature of the utility model are described with reference to attached drawing, example is served only for explaining that this practicality is new Type, is not intended to limit the scope of the utility model.

Example 1

The shape of the utility model, construct as shown in attached drawing 9 and attached drawing 1, attached drawing 2, and attached drawing 9 is each portion of the utility model Part assembles schematic three dimensional views, and attached drawing 1 uses preceding view for nail, and attached drawing 2 uses rear view for nail.This reality It is connected with the hexagon head of a nail described in Novel nail with the rivet nut of tool thread cavity and one is made, two latches is located under rivet nut In the square aperture at end (such as attached drawing 3, Fig. 4), latch (such as attached drawing 5, Fig. 6) in push-in, makes interior two scarves in latch lower end The scarf with two in tool horizontal latches (such as attached drawing 7, Fig. 8) is connected respectively, and nail is then immersed tool antirust and prevents group The solidifying oil that part slides is completed.The square aperture in the rivet nut of tool internal thread cavity is overlayed using preceding latch, is used Afterwards, two horizontal latches are released and are caught in nailed object by interior latch along hole.

Example 2

The utility model nail is as plank nail in use, to bind wooden in being placed on floor or platform first Plate, nail is first hammered into nail hammer, after knock in interior latch, two pairs of scarves of latch, can release latch rivet nut and embedded plank In, the utility model nail can prevent nail from loosening to exit, its riveted ability is much better than to depend merely on frictional force due to there is two latches Common nails.In addition, latch tightly blocks plank in the plane perpendicular to nail, opposite turn between plank can be also prevented It is dynamic.

Embodiment 3

As expansion bolt substitute, when the utility model nail of large size hammers into wall or ground, knock in nail and insert Sell, then two in nail latch insertion ground or wall, the effect after being expanded equivalent to expansion bolt, after latch is knocked in, Expose helicoid cavity above nail, be screwed into bolt or screw so as to fulfill it is identical with expansion bolt the effect of.

In the example, the use of the utility model nail, simple and fast, aids in without electric drill.
