The purpose of the utility model can be realized by the following technical proposal: the foot nail comprises a foot nail body made of plastics, wherein the foot nail body comprises a nail cap and a nail rod, and is characterized in that the nail rod is cylindrical, external threads I are arranged on the outer wall surface of the nail rod, a core rod made of a metal material is inserted into the nail rod in a penetrating mode, and a gap is reserved between the upper end of the core rod and the inner wall surface of the upper end of the nail rod.

In the foot nail, the outer wall surface of the core rod is provided with a second external thread.

In the foot nail, the top surface of the core bar is lower than or equal to the top surface of the nail rod.

In the foot nail, the bottom end of the core rod is positioned in the nail cap.

In the above-described leg nail, the nail shaft has a flared portion at a distal end of an inner wall surface thereof.

In the foot nail, the lower part of the core rod is also provided with a core cap, and the size of the core cap is larger than the diameter of the core rod.

In the above-mentioned foot nail, the bottom surface of the nail cap is made into a cambered surface.

In the foot nail, the side surface of the nail cap is provided with a plurality of concave holes.

In the above foot nail, the foot nail body is made of nylon.

Compared with the prior art, the utility model discloses a core bar that metal material made and the plastics foot nail body at the outside injection moulding of core bar both have higher structural strength, solve the not hard up drawback when cooperating with metalwork screw thread through setting up at the outside plastics thread of nail pole simultaneously again.

Fig. 2 is a schematic diagram of a half-section structure of the present invention.

In the figure, 1, a foot nail body; 2. a nail cap; 3. a nail rod; 4. the first external thread; 5. a core bar; 6. a second external thread; 7. a flared part; 8. a core cap; 9. a concave hole.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1 and 2, the present embodiment is a foot nail, including a foot nail body 1 made of plastic, the foot nail body 1 includes a nail cap 2 and a nail rod 3, the nail rod 3 is cylindrical, an external thread 4 is provided on an outer wall surface of the nail rod 3, a core bar 5 made of a metal material is inserted into the nail rod 3, and a gap is provided between an upper end of the core bar 5 and an inner wall surface of an upper end of the nail rod 3.

This foot nail uses core bar 5 to do as the inner core and fix when the preparation, then injection moulding makes foot nail body 1 on the outer wall of core bar 5, when moulding plastics, the upper end of core bar 5 is connected on injection mold, this injection mold has formed the clearance between core bar 5 and the nail pole 3, the formation in this clearance is convenient for the foot nail 3 can carry out the shrinkage of small amplitude when the screw in work piece for it is more smooth and easy to twist.

Further, the outer wall surface of the core rod 5 is provided with an external thread II 6. The external thread two 6 not only makes the connection degree of the nail rod 3 of the foot nail body 1 made of plastics and the core rod 5 higher, is not easy to loosen, but also can ensure that the core rod 5 is screwed with an injection mold when the injection mold is used for injection molding, and the connection is more convenient and is not easy to shift.

Further, the top surface of the core bar 5 is lower than or equal to the top surface of the nail rod 3.

Further, the bottom end of the core rod 5 is positioned in the nail cap 2.

Further, the nail shaft 3 has a flared portion 7 at the tip of the inner wall surface.

Further, the lower part of the core rod 5 is also provided with a core cap 8, and the size of the core cap 8 is larger than the diameter size of the core rod 5.

Further, the bottom surface of the nail cap 2 is made into a cambered surface.

Furthermore, a plurality of concave holes 9 are arranged on the side surface of the nail cap 2. The concave hole 9 is used as a force transferring hole, so that labor is saved when the foot nail is transferred into a workpiece.

Further, the material of the nail body 1 is nylon.

Further, the core rod is made of stainless steel or aluminum materials.

This embodiment includes that metal material makes's core bar 5 and at 5 outside injection moulding's of core bar plastics foot nail body 1, both had higher structural strength, simultaneously again through setting up the plastics thread in 1 nail pole 3 outsides of foot nail body can solve effectively with the not hard up drawback of metalwork screw-thread fit, but also have and adjust smooth function.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
