The invention discloses a kind of knob type anticreep member to follow closely, it is characterized in that including nail rod and the head of a nail, nail rod front end is provided with nail tip, the head of a nail is connected to nail rod rear end, and head of a nail rear end is provided with prism hole, and nail rod is provided with one to three-start screw, screw thread is half-turn a to circle by nail rod rear end to front end, screw thread is provided with threadingly the fracture port of distribution up and down, and fracture port length is more than one millimeter, and fracture port is deep to nail rod surface；Engagement is firm, is bitten wood snail line upwards by the termination of screw thread breaking part upward during pulling capacity, connection reliability is higher.
Description
Technical field
The present invention relates to a kind of device being reliably connected for timber, is followed closely more particularly to a kind of knob type anticreep member.
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, two timber are made to link together, because nail tip side timber nail rod straight cutting enters
Enter, stress is easy to pull-off and come out, and connection reliability is low, occurs a kind of member nail of front curvature for this, how by bending
Member hammers into timber, is still solved up for technology.
The content of the invention
In order to solve the above problems, the invention provides a kind of knob type anticreep member to follow closely.
The technical solution adopted by the present invention is：A kind of knob type anticreep member nail, it is characterised in that including nail rod and the head of a nail, nail
Bar front end is provided with nail tip, and the head of a nail is connected to nail rod rear end, and head of a nail rear end is provided with prism hole, and nail rod is provided with one to three-start screw,
Screw thread is that half-turn a to circle, screw thread is provided with the fracture port being threadingly distributed up and down, fracture port length by nail rod rear end to front end
More than one millimeter, fracture port is deep to nail rod surface.
Further, 1 to one/3rd times of the fracture port length equal to reach between adjacent fracture port.
Further, reach is more than nail rod radius between the adjacent fracture port.
Further, the nail rod length is five times to 20 times of its diameter.
The present invention is used to connect in two blocks of timber, and nail tip is first hammered into timber straight during use, then first with hammering into instrument
Sleeve entangle first nail, annular boss is fallen on timber, the prism hole hammered on the prism insertion head of a nail of instrument push rod lower end, fixed
Position sleeve, push rod is hammered downwards and hammers into first nail, the spiral salient on push rod glides along the thread groove in sleeve pipe, push rod rotating band
The dynamic descending member nail synchronous rotary for hammering into timber, push rod rotation downstream rate is consistent with first oncomelania line feed rotation downstream rate,
Member nail, which is rotating, hammers into timber, and wood internal forms the lossless screw thread being coincide with nail rod screw thread, and engagement is firm, by pulling capacity
When screw thread breaking part termination upward bite wood snail line upwards, connection reliability is higher.
Brief description of the drawings
Fig. 1 is integrality schematic diagram of the embodiment of the present invention.
Fig. 2 is the embodiment of the present invention and top such as instrument mated condition schematic diagram.
Reference:1 nail rod；2 heads of a nail；3 prism holes；4 screw threads；5 fracture ports；6 sleeve pipes；7 push rods；8 annular boss；9 spiral shells
Groove；10 end caps；11 prisms；12 spiral salients.
Embodiment
The embodiment of the present invention is used for being reliably connected for timber, as shown in figure 1, knob type anticreep member nail is provided with the He of nail rod 1
The head of a nail 2, nail rod front end are provided with nail tip, and the head of a nail is connected to nail rod rear end, and head of a nail rear end is provided with prism hole 3, nail rod be provided with one to
Three-start screw 4, the present embodiment are three, and screw thread is that half-turn a to circle, the present embodiment encloses close to one by nail rod rear end to front end, spiral shell
Line is provided with threadingly the fracture port 5 of distribution up and down, and fracture port length is more than one millimeter, and fracture port is deep to nail rod surface, can be with
Wood snail line is bitten in vertical extract, difficulty is extracted in increase, and fracture threaded upper end can become to up hand of spiral phase backward extrusion
Shape, check effect are more preferable.
In order that the member nail rotation of knob type anticreep hammers into timber, knob type member nail installation tool is additionally provided, such as Fig. 2 institutes
Show, provided with sleeve pipe 6 and push rod 7, sleeve pipe is a hollow pipe, and its lower end is provided with an outstanding annular boss 8, for positioning
With the stress of unit area, downward sharp protrusion can be arranged below in annular boss, being used for positioning during use prevents from rotating,
Can be to be connected with handle on sleeve pipe or annular boss, holding handle prevents its rotation, can also its lower end be provided with through side wall
Gap be provided with as peep hole, in sleeve pipe by upper end stretch downwards one to three-start screw groove 9, thread groove pitch and first oncomelania line
Pitch it is equal, push rod is coordinated from top plug-in-sleeve and shell clearance, and push rod upper end is provided with end cap 10, is followed closely for impacting nail,
Push rod lower end is provided with prism 11 prominent in opposite directions, and the spiral salient 12 being coincide with thread groove is provided with outside push rod hypomere, can be with
Push rod rotation is driven during push rod is descending.
The present invention is used to connect in two blocks of timber, and nail tip is first hammered into timber straight during use, then first with hammering into instrument
Sleeve entangle first nail, annular boss is fallen on timber, the prism hole hammered on the prism insertion head of a nail of instrument push rod lower end, fixed
Position sleeve, push rod is hammered downwards and hammers into first nail, the spiral salient on push rod glides along the thread groove in sleeve pipe, push rod rotating band
The dynamic descending member nail synchronous rotary for hammering into timber, push rod rotation downstream rate is consistent with first oncomelania line feed rotation downstream rate,
Member nail, which is rotating, hammers into timber, and wood internal forms the lossless screw thread being coincide with nail rod screw thread, and engagement is firm, by pulling capacity
When screw thread breaking part termination upward bite wood snail line upwards, connection reliability is higher.
During implementation, fracture port length is equal to 1 to one/3rd times of reach between adjacent fracture port, can be more preferable
Anticreep；Reach is more than nail rod radius between adjacent fracture port, and the effect that is screwed is preferable；Nail rod length is five times of its diameter
To 20 times, it is more suitable for setting member nail.
It is only present pre-ferred embodiments in summary, all equivalent modification done according to the application and prior art additions are equal
It is considered as the technology of the present invention category.
