Description
Technical field
A kind of device being reliably connected for timber is the utility model is related to, more particularly to a kind of member nail installation of knob type
Instrument.
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, occurs a kind of needs with interrupted screw-thread for this and rotate hammer into first following closely, its how to hammer into still up for
Technology solves.
Utility model content
In order to solve the above problems, the utility model provides a kind of knob type member nail installation tool.
The technical solution adopted in the utility model is：A kind of knob type member nail installation tool, it is characterised in that including sleeve pipe
And push rod, sleeve pipe are a hollow pipe, its lower end is provided with an outstanding annular boss, is provided with sleeve pipe and is stretched downwards by upper end
The one of exhibition is to three-start screw groove, and for push rod with top plug-in-sleeve and shell clearance, push rod upper end is provided with end cap, push rod lower end
Provided with prism prominent in opposite directions, the spiral salient being coincide with thread groove is provided with outside push rod hypomere.
Further, downward sharp protrusion is arranged below in the annular boss.
Further, described sleeve pipe lower end is provided with the gap through side wall.
Further, it is connected with handle on described sleeve pipe or annular boss.
The utility model 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
The sleeve of instrument entangles first nail, and annular boss is fallen on timber, the prism hammered on the prism insertion head of a nail of instrument push rod lower end
Hole, abutment 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
Rotation drives the descending member nail synchronous rotary for hammering into timber, push rod rotation downstream rate and first oncomelania line feed rotation downstream rate
Unanimously, member nail, which is rotating, hammers into timber, and engagement is firm, and wood is bitten upwards by the termination of screw thread breaking part upward during pulling capacity
Screw thread, connection reliability is higher, hammers into rotation using this instrument and vertical feed is in time and synchronous, be easy to be formed in wood internal
The lossless wood snail line being coincide with nail rod screw thread, beneficial to solid and reliable connection.
Brief description of the drawings
Fig. 1 is the utility model embodiment decomposing schematic representation.
Fig. 2 is the utility model embodiment schematic cross-sectional view.
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 utility model embodiment is to rotate the instrument for hammering into a kind of knob type anticreep member, knob type anticreep member nail such as Fig. 1,
Shown in 2, provided with nail rod 1 and the head of a nail 2, nail rod 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
3, nail rod is provided with one to three-start screw 4, and the present embodiment is three, and screw thread is half-turn a to circle by nail rod rear end to front end, this
For embodiment close to a circle, screw thread is provided with threadingly the fracture port 5 of distribution up and down, and fracture port length is more than one millimeter, fracture port
Nail rod surface is deep to, wood snail line can be bitten in vertical extract, difficulty is extracted in increase, and fracture threaded upper end can be to up spiral shell
Crimp in opposite direction is revolved, check effect is more preferable.
For hammering into the knob type member nail installation tool of above-mentioned member nail, as shown in Figure 1, 2, provided with sleeve pipe 6 and push rod 7, set
Guan Weiyi hollow pipes, its lower end are provided with an outstanding annular boss 8, can be for positioning and the stress of unit area
Annular boss is arranged below downward sharp protrusion, and being used for positioning during use prevents from rotating, can also be on sleeve pipe or annular boss
Be connected with handle, holding handle prevents its rotation, can also its lower end be provided with gap through side wall as peep hole, in sleeve pipe
Provided with one stretched downwards by upper end to three-start screw groove 9, thread groove pitch is equal with the pitch of first oncomelania line, and push rod is by top
Plug-in-sleeve coordinates with shell clearance, and push rod upper end is provided with end cap 10, and for impacting nail nail, push rod lower end is provided with prominent in opposite directions
Prism 11, push rod hypomere outside are provided with the spiral salient 12 being coincide with thread groove, top can be driven during push rod is descending
Bar rotates.
The utility model 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
The sleeve of instrument entangles first nail, and annular boss is fallen on timber, the prism hammered on the prism insertion head of a nail of instrument push rod lower end
Hole, abutment 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
Rotation drives the descending member nail synchronous rotary for hammering into timber, push rod rotation downstream rate and first oncomelania line feed rotation downstream rate
Unanimously, member nail, which is rotating, hammers into timber, and engagement is firm, and wood is bitten upwards by the termination of screw thread breaking part upward during pulling capacity
Screw thread, connection reliability is higher, hammers into rotation using this instrument and vertical feed is in time and synchronous, be easy to be formed in wood internal
The lossless wood snail line being coincide with nail rod screw thread, beneficial to solid and reliable connection.
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, being also adapted to property of instrument is servo-actuated arrange parameter.
It is only in summary the utility model preferred embodiment, all equivalent modification done according to the application and prior art add
Add and be accordingly to be regarded as the utility model technology category.
