Description
Technical field
A kind of device being reliably connected for timber is the utility model is related to, is reliably connected more particularly to a kind of parted hair formula
Member nail.
Background technology
Member nail is often used as hardware-joint in production and construction timber combines connection, and existing member nail is all solid list
Bar, during use in the straight connection of insertion two timber, makes two timber link together, due to nail tip side timber nail rod straight cutting into
Enter, stress is easy to pull-off and comes out, and connection reliability is low, how to be reliably connected using member nail realization and is still solved up for technology.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of parted hair formula and is reliably connected first nail.
The technical solution adopted in the utility model is：A kind of parted hair formula is reliably connected first nail, it is characterised in that is followed closely including core
With main nail, main nail is equipped with nail rod and the head of a nail, and nail rod is divided into two sections of nail rod leading portion and nail rod back segment, and nail rod leading portion front end is equipped with nail
Point, nail rod leading portion shaft core position are equipped with from the front to the back to the circular hole at nail tip position, and nail tip is equipped with least two with nail rod axis
For the through hole of the circumferentially equidistant distribution of axis, through hole is spent angles in 30 to 45 for its axis of circular hole and nail rod leading portion axis, is passed through
Perforation upper end is open into circular hole bottom, and through hole lower end is open on the nail tip conical surface, and core nail is equipped with each through hole upper end one by one
Corresponding vertical core bar, core bar lower end are equipped with conical points, and core bar upper end is connected with the core cap coincideing in circular hole, nail rod back segment tail
End is connected with the head of a nail, and nail rod back segment is equipped with the core bore rearwardly through the head of a nail, and the front end of nail rod back segment, which is equipped with, passes through screw thread and nail rod
The annular convex platform being pressed on core cap of leading portion rear end connection.
Further, the through hole is three.
Further, the core bore is equipped with end cap.
Further, the core bar is a diameter of through 90 70 the percent to percent of bore dia.
The utility model is used for the connection between upper and lower two timber, and when use first hammers into timber by main, then uses mandril
Core bore is inserted into core cap, mandril is tapped and pushes each core bar using core cap, core bar enters through hole under the guiding of through hole to side
Side changes direction, and insertion side balk, it is not easy to which pull-off, is connected firmly.
Brief description of the drawings
Fig. 1 is the utility model embodiment overall schematic.
Fig. 2 is the utility model embodiment schematic cross-sectional view.
Reference numeral:1 head of a nail；2 nail rod leading portions；3 nail rod back segments；4 nail tips；5 circular holes；6 through holes；7 core bars；8 conical points；
9 core caps；10 core bore；11 annular convex platform.
Embodiment
As shown in Figure 1, 2, which is reliably connected member nail and is used between upper and lower two timber the utility model embodiment
Connection, is equipped with nail rod and the head of a nail 1, nail rod is divided into 3 two sections of nail rod leading portion 2 and nail rod back segment, nail rod equipped with core nail and main nail, main nail
Leading portion front end is equipped with nail tip 4, and nail rod leading portion shaft core position is equipped with to be equipped with extremely to the circular hole 5 at nail tip position, nail tip from the front to the back
Few two through holes 6 using nail rod axis as the circumferentially equidistant distribution of axis, the present embodiment through hole are three, the present embodiment three
A, through hole is open into circular hole bottom for its axis of circular hole and nail rod leading portion axis in 30 to 45 degree angles, through hole upper end,
Through hole lower end is open on the nail tip conical surface, and core nail is equipped with and each through hole upper end vertical core bar 7 correspondingly, core bar lower end
Equipped with conical points 8, core bar upper end is connected with the core cap 9 coincideing in circular hole, and nail rod back segment tail end is connected with the head of a nail, nail rod back segment
Equipped with the core bore 10 rearwardly through the head of a nail, the front end of nail rod back segment is equipped with is pressed in core by screw thread with what nail rod leading portion rear end was connected
Annular convex platform 11 on cap.
The utility model is used for the connection between upper and lower two timber, and when use first hammers into timber by main, then uses mandril
Core bore is inserted into core cap, mandril is tapped and pushes each core bar using core cap, core bar enters through hole under the guiding of through hole to side
Side changes direction, and insertion side balk, it is not easy to which pull-off, is connected firmly.
During implementation, end cap can be equipped with core bore, for decorating, core bar it is a diameter of through bore dia 70 percent to
90 percent, it is more conducive to core bar deformation.
It is only in summary the utility model preferred embodiment, all equivalent modification done according to the application and the prior art add
Add and be accordingly to be regarded as the utility model technology category.
