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 centering type
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 centering type and is reliably connected first nail.
The technical solution adopted in the utility model is：A kind of centering type is reliably connected first nail, it is characterised in that including main nail
And eccentric nail, main nail are equipped with nail rod and the head of a nail, nail rod front end is equipped with nail tip, and nail rod tail end is connected with the head of a nail, and nail rod side wall is equipped with
The side channel stretched by head of a nail extroversion nail tip direction, the head of a nail are equipped with the vertical core opposite with side channel, and side channel front end is connected with one and runs through
The inclined hole of nail rod, inclined hole lower end position is than side channel front end close to nail tip, and inclined hole axis intersects with side channel axis and both are in be more than
135 degree of angles, eccentric nail are equipped with a guide rod coincideing with side channel penetrated by vertical core, and guide rod front end is connected with transversal
The face area locating rod that leans against side channel on the inside of smaller than guide rod cross-sectional area, locating rod front end are equipped with beveled tip, and beveled tip tip is leaned on
On the inside of side channel, eccentric nail length is more than the sum of side channel and inclined hole length.
Further, the side channel is C-shaped channel or dovetail groove.
Further, the guide rod and locating rod are same material integrally connected.
Further, the guide rod and locating rod are different material integrally connected, and guide rod hardness is more than locating rod hardness.
Further, the side channel front end apart from nail tip distance for nail rod length half to a quarter it
Between.
Further, the vertical core is equipped with gap at head of a nail edge.
Further, it is respectively equipped with the guide rod and side channel and coordinates sliding slot and protrusion.
The utility model is used for the connection between upper and lower two timber, and main hammer into first is needed two timber of connection during use
In, then then the locating rod of eccentric nail and beveled tip pound with a hammer under beveled tip guiding role towards insertion vertical core on the inside of side channel
Side channel is squeezed into, the beveled tip of locating rod is contacted with the sloped inner face of inclined hole, then proceedes to tap eccentric nail downwards, beveled tip is along inclined hole
Sloped inner face change direction, guiding positioning rod bending along inclined hole to side insertion lower part second block of timber, until guide rod with
The head of a nail is concordant, realizes that main nail intersects locking with second block of lower part timber, and main nail and eccentric nail are not easy pull-off, are connected firmly,
Making easy to process.

Embodiment
As shown in Figure 1, 2, which is reliably connected member nail and is used between upper and lower two blocks of timber the utility model embodiment
Be reliably connected, including main nail and eccentric nail, main nail are equipped with nail rod 1 and the head of a nail 2, and nail rod front end is equipped with nail tip 3, nail rod tail end and
The head of a nail connects, and nail rod side wall is equipped with the side channel 4 stretched by head of a nail extroversion nail tip direction, and side channel can be C-shaped channel or dovetail groove, this reality
Apply example to be completed by beveled tip for opening groove guiding function, the head of a nail is equipped with the vertical core 5 opposite with side channel, this implementation vertical core is on head of a nail side
Along being equipped with open gap 6, setting easy to process and side channel unicom, side channel front end is connected with the inclined hole 7 of consistent drift bolt bar, before side channel
Apart from the half that the distance of nail tip is nail rod length, the inclined hole to after between a quarter, hammering into two timber is located at lower part at end
Second piece of wood internal, inclined hole lower end position is than side channel front end close to nail tip, and inclined hole axis intersects with side channel axis and both are in
More than 135 degree angles, angle is more big more is conducive to eccentric nail locating rod curved side and inserts, and the present embodiment angle is 135
Degree, ensure that bending is easy while ensureing that locating effect is inserted in side, eccentric nail be equipped with one penetrated by vertical core coincide with side channel
Guide rod 8, guide rod front end are connected with the cross-sectional area locating rod 9 that leans against side channel on the inside of smaller than guide rod cross-sectional area, positioning
Bar front end is equipped with the beveled tip 11 formed by inclined-plane 10, and beveled tip tip is leaned against on the inside of side channel, and eccentric nail length is more than side channel and inclined hole
The sum of length, inclined hole diameter are more than the diameter of locating rod, are readily bent and have the curved space, the present embodiment guide rod and locating rod
For same material integrally connected, the irony being readily bent or aluminum or alloy material, guide rod and locating rod can be used to be alternatively different material
Matter integrally connected, guide rod hardness is more than locating rod hardness, easy to be oriented to and deform.
The utility model is used for the connection between upper and lower two timber, and main hammer into first is needed two timber of connection during use
In, then then the locating rod of eccentric nail and beveled tip pound with a hammer under beveled tip guiding role towards insertion vertical core on the inside of side channel
Side channel is squeezed into, the beveled tip of locating rod is contacted with the sloped inner face of inclined hole, then proceedes to tap eccentric nail downwards, beveled tip is along inclined hole
Sloped inner face change direction, guiding positioning rod bending along inclined hole to side insertion lower part second block of timber, until guide rod with
The head of a nail is concordant, realizes that main nail intersects locking with second block of lower part timber, and main nail and eccentric nail are not easy pull-off, are connected firmly,
Making easy to process.
It can be respectively equipped with during implementation on guide rod and side channel and coordinate sliding slot and protrusion, prevent guide rod rotation beveled tip deflection.
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.
