Description
Technical field
The present invention relates to a kind of plank connected nail.
Background technology
The connection of two planks connects by nail, and right and wrong are usually used and connected mode easily. But, the easy loose or dislocation of current nail, two plank connections are insecure, easily throw off, and make the installation firmness of plank low.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of plank connected nail, plank is connected more firm, be difficult for throwing off.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of plank connected nail, comprise main nail and secondary nail, described main nail is made up of main ailhead and main nail post, main ailhead and main nail post are column, the outer circumference surface of main ailhead is provided with back-off, on the shaft of main nail post, be evenly provided with teeth, the middle part of described main ailhead is provided with endoporus, described secondary nail is made up of secondary ailhead and correcting cylinder, described correcting cylinder is arranged at the head end of described secondary ailhead, described secondary ailhead is diameter by the diminishing taper of tail end head-end, described secondary ailhead is inserted in the endoporus of described main ailhead by the guiding of described correcting cylinder.
Further, the inwall of the endoporus that described main ailhead middle part is provided with is provided with internal thread, and the outer surface of described secondary ailhead is provided with external screw thread.
Further, the outer circumference surface of described main ailhead offers two flutings that are communicated with described endoporus vertically, and these two flutings are with respect to the axial line symmetry of main ailhead.
The invention has the beneficial effects as follows: the present invention is made up of main nail and secondary nail, and the secondary ailhead of secondary nail, under the guide effect of correcting cylinder, can be inserted in the endoporus of main ailhead of main nail, and because the head end diameter of secondary ailhead is less than tail end diameter, secondary nail difficult drop-off; The main nail of combining and secondary binding after the installing hole of front plate, by beaing the outer end of main nail post, make in the whole installing hole that packs by force front plate into of main ailhead of this plank connected nail, because the head end diameter of secondary ailhead is less than tail end diameter, under the effect of the diameter increasing gradually at secondary ailhead, can make the external diameter of main ailhead become large, and then can with the installing hole close-fitting of front plate, simultaneously again because the outer circumference surface of main ailhead is provided with back-off, more make this plank connected nail pack difficult drop-off after front plate into; Dress is when side plate, by beaing side plate, winner followed closely in the installing hole that post packs side plate by force into, and because main nail post is provided with teeth, can with tightly interlock of side plate, make side plate difficult drop-off. Plank connected nail of the present invention is very firm to the connection of plank, and interconnective plank is not easily separated, has increased the security reliability that plank connects.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figures 1 to 4, a kind of plank connected nail, comprise main nail 1 and secondary nail 2, described main nail 1 is made up of main ailhead 11 and main nail post 12, main ailhead 11 and main nail post 12 are column, the outer circumference surface of main ailhead 11 is provided with back-off 111, on the shaft of main nail post 12, be evenly provided with teeth 121, the middle part of described main ailhead 11 is provided with endoporus 112, described secondary nail 2 is made up of secondary ailhead 21 and correcting cylinder 22, described correcting cylinder 22 is arranged at the head end of described secondary ailhead 21, described secondary ailhead 21 is diameter by the diminishing taper of tail end head-end, described secondary ailhead 21 is inserted in the endoporus 112 of described main ailhead 11 by the guiding of described correcting cylinder 22.
The inwall of the endoporus 112 that main ailhead 11 middle parts are provided with is provided with internal thread, and the outer surface of secondary ailhead 21 is provided with external screw thread.
The outer circumference surface of main ailhead 11 offers two flutings 113 that are communicated with described endoporus 112 vertically, and these two the fluting 113 axial line symmetries with respect to main ailhead 11.
Utilize the concrete steps of this plank connected nail connection plank as follows:
First, as shown in Figure 4, the secondary ailhead 21 of pair nail 2 is inserted in the endoporus 112 of main ailhead 11 of main nail 1 under the guide function of correcting cylinder 22, because the head end diameter of secondary ailhead 21 is less than tail end diameter, thus secondary nail 2 difficult drop-offs;
Then, as shown in Figure 5 and Figure 6, the pair nail 2 being assembled together and the main ailhead 11 of main nail are first inserted in the installing hole of front plate 3, beat the outer end of main nail post 12 with rubber hammer, winner's ailhead 11 entirety are packed in the installing hole of front plate 3 by force. And, in main nail post 12, be provided with guide hole, after main ailhead 11 assembles with the installing hole of front plate 3, the final guide hole that inserts of correcting cylinder 22,21 of secondary ailheads are inserted in the endoporus 112 of main ailhead 11 completely. Because the head end diameter of secondary ailhead 21 is less than tail end diameter, under the effect of the diameter increasing gradually at secondary ailhead 21, can make the cylindrical of main ailhead 11 expand, it is large that external diameter becomes, and then can with the installing hole close-fitting of front plate 3, simultaneously again because the outer circumference surface of main ailhead 11 is provided with back-off 111, back-off 111 and tightly interlock of front plate 3, thus more make the main ailhead 11 of this plank connected nail pack the rear difficult drop-off of front plate 3 into;
Finally, as shown in Figure 7 and Figure 8, side plate 4 is packed into. When assembling, beat side plate 4 with rubber hammer, winner is followed closely in the installing hole that post 12 packs side plate 4 by force into, and because main nail post 12 is provided with teeth 121, make side plate 4 and the tightly interlock of main nail post 12, difficult drop-off.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
