Description
Technical field
The utility model relates to a kind of plank connecting nail.
Background technique
The connection of two planks connects by nail, and right and wrong are usually used and Placement easily.But, the easy loose or dislocation of current nail, two plank connections are insecure, easily throw off, and make the installation fastness of plank low.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of plank connecting nail, plank is connected more firm, is difficult for throwing off.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of plank connecting nail, comprise main nail and secondary nail, described main nail is comprised of main ailhead and main nail post, main ailhead and main nail post are column, the outer peripheral 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 comprised 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 outside thread.
Further, the outer peripheral surface of described main ailhead offers two flutings that are communicated with described endoporus vertically, and these two flutings are symmetrical with respect to the shaft axis of main ailhead.
The beneficial effects of the utility model are: the utility model is comprised of main nail and secondary nail, the secondary ailhead of secondary nail is under the leading role 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 mounting hole of front plate, by beaing the outer end of main nail post, make in the whole mounting hole that packs by force front plate into of the main ailhead of this plank connecting 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 mounting hole close-fitting of front plate, simultaneously again because the outer peripheral surface of main ailhead is provided with back-off, more make this plank connecting nail pack difficult drop-off after front plate into; Dress is during side plate, by beaing side plate, winner followed closely in the mounting 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 connecting nail of the present utility model is very firm to the connection of plank, and interconnective plank is not easily separated, has increased the safety reliability that plank connects.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figures 1 to 4, a kind of plank connecting nail, comprise main nail 1 and secondary nail 2, described main nail 1 is comprised of main ailhead 11 and main nail post 12, main ailhead 11 and main nail post 12 are column, the outer peripheral 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 comprised 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 outside thread.
The outer peripheral surface of main ailhead 11 offers two flutings 113 that are communicated with described endoporus 112 vertically, and these two fluting 113 shaft axiss with respect to main ailhead 11 are symmetrical.
Utilize the concrete steps of this plank connecting nail connection plank as follows:
First, as shown in Figure 4, the secondary ailhead 21 of pair nail 2 is inserted under the guide function of correcting cylinder 22 in the endoporus 112 of main ailhead 11 of main nail 1, 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 mounting hole of front plate 3, with rubber hammer, beat the outer end of main nail post 12, winner's ailhead 11 integral body are packed in the mounting hole of front plate 3 by force.And, in main nail post 12, be provided with guide hole, after the mounting hole of main ailhead 11 and front plate 3 assembles, 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 mounting hole close-fitting of front plate 3, while is provided with back-off 111 due to the outer peripheral surface of main ailhead 11 again, back-off 111 and tightly interlock of front plate 3, thus more make the main ailhead 11 of this plank connecting 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.During assembling, with rubber hammer, beat side plate 4, winner is followed closely in the mounting 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 embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification 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 utility model.
