Description
Technical field
A kind of wooden boards attachment screw of the utility model is related in a kind of wooden boards process, carries out to plate
The attachment screw being connected and fixed belongs to woodworking equipment field.It is in particular to a kind of to be screwed in hollow stem in plate by rotary-cut sword,
And enter cutting clast in hollow stem, the attachment screw of mobile discharge is carried out then along the internal screw thread on hollow stem inner wall.
Background technique
Currently, when carrying out plate connection, often needing to carry out plate by attachment screw in woodworking process of manufacture
Material is connected and fixed, and when directly screwing in screw in plate, screw is squeezed with plate, is easy to make plate from screw position distending
The case where cracking influences the tightness of connection, destroys the integrality of plate, existing frequently-used screw, publication number
CN1509366 discloses the screw with cutting function, which is manufactured with whole pressed form, which includes head
(50), bar portion (30) and tip (12), and at least one cutting member (20) is set, the cutting member is radial from bar portion (3)
Extend outwardly.Cutting member (20) is separately sufficient to accommodate at a distance from gasket (40) with head (50), and is cut on synthetic plate
System opening is to make material expand and shrink, without being damaged by caused by shank (30).Screw (10) further includes extending to
The screw thread (11) at tip (12) and at least one extend through the cutting surface (15) of the screw thread (11) of tip (12) nearby, so as to
It penetrates and self tapping enters wooden or metal support structure, when carrying out plate cutting using the screw, clast caused by cutting passes through
Screw outside screw is exported, and during screw screws in, loose clast and screw mutual extrusion make screw hole cycle side plate
Material stress is larger, is easy to strut plate, be damaged, using effect is bad.
Summary of the invention
In order to improve above situation, a kind of wooden boards attachment screw of the utility model provides one kind will by rotary-cut sword
Hollow stem screws in plate, and enters cutting clast in hollow stem, is moved then along the internal screw thread on hollow stem inner wall
The attachment screw of dynamic discharge.Plate can not be squeezed during screw-in, prevent plate cracking damage.
A kind of wooden boards attachment screw of the utility model is achieved in that a kind of wooden boards connection of the utility model
Screw is formed by hollow stem, into bits slot, limited block, chip removal chamber, card slot, side edge, rotary-cut sword, external screw thread and internal screw thread, limited block
It being placed on hollow stem one end, the limited block diameter is gradually increased from bottom to top, it is provided with chip removal chamber in the middle part of the limited block,
And be connected inside hollow stem, be provided with multiple card slots at the top of the limited block, rotary-cut sword is placed on the hollow stem other end, described
It is provided with multiple chamferings on rotary-cut sword, external screw thread is equipped on the hollow stem outer wall, is equipped with internal screw thread on the hollow stem inner wall, it is more
A side edge is equidistantly placed on hollow stem outer wall, be provided in the hollow stem it is multiple into bits slot, and with multiple side edges correspond, institute
It states into bits slot position in the side of corresponding side edge.
In use, screw installation tool is stuck on limited block by card slot, by screw installation tool rotary hallow stem,
Hollow stem drives the rotation of rotary-cut sword, and then rotary-cut sword cuts plate, and hollow stem follows rotary-cut sword gradually to screw in plate
Portion, and then hollow stem is not squeezed with plate, prevents plate from cracking from screw position, the side edge on hollow stem outer wall is to screw thread
Hole side wall is cut, and clast caused by cutting into bits slot by entering inside hollow stem, then along on hollow stem inner wall
The upward spiral of internal screw thread it is mobile, then into the atria in limited block, be finally discharged, and then prevent clast stripper plate
Material reaches in wooden boards process, and fixed purpose is attached to plate.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, cheap, it is easy to spread.
Three, plate can not be squeezed during screw-in, prevents plate cracking damage.
Detailed description of the invention
Fig. 1 is a kind of three-dimensional structure diagram of wooden boards attachment screw of the utility model.
Fig. 2 is a kind of externally threaded three-dimensional structure diagram of wooden boards attachment screw sliding panel of the utility model.
In attached drawing
Wherein part are as follows: hollow stem (1), into bits slot (2), limited block (3), chip removal chamber (4), card slot (5), side edge (6), rotation
Cutting blade (7), external screw thread (8), internal screw thread (9).
Specific embodiment:
A kind of wooden boards attachment screw of the utility model be achieved in that by hollow stem (1), into bits slot (2), limit
Block (3), chip removal chamber (4), card slot (5), side edge (6), rotary-cut sword (7), external screw thread (8) and internal screw thread (9) composition, limited block (3)
It is placed on hollow stem (1) one end, limited block (3) diameter is gradually increased from bottom to top, is opened in the middle part of the limited block (3)
Have chip removal chamber (4), and be connected with hollow stem (1) inside, is provided with multiple card slots (5), rotary-cut sword at the top of the limited block (3)
(7) it is placed on hollow stem (1) other end, multiple chamferings is provided on the rotary-cut sword (7), are equipped on hollow stem (1) outer wall
External screw thread (8) is equipped with internal screw thread (9) on hollow stem (1) inner wall, and multiple side edges (6) are equidistantly placed in hollow stem (1) outer wall
On, be provided on the hollow stem (1) it is multiple into bits slot (2), and with multiple side edges (6) correspond, it is described into bits slot (2) be located at
The side of corresponding side edge (6).
In use, screw installation tool is stuck on limited block (3) by card slot (5), rotated by screw installation tool
Hollow stem (1), hollow stem (1) drive rotary-cut sword (7) rotation, and then rotary-cut sword (7) cuts plate, hollow stem (1) with
It is gradually screwed in inside plate with rotary-cut sword (7), and then hollow stem (1) is not squeezed with plate, prevents plate from screw position
Cracking, the side edge (6) on hollow stem (1) outer wall cut threaded hole side wall, and clast caused by cutting is by into bits slot (2)
Hollow stem (1) inside is entered, then along the internal screw thread (9) on hollow stem (1) inner wall, spiral is mobile upwards, subsequently into
It into the atria in limited block (3), is finally discharged, and then prevents clast extrusion plate；
The design that limited block (3) diameter is gradually increased from bottom to top can limit hollow stem (1),
It prevents the utility model from entirely screwing in inside plate, is not easy to dismantle；
It is provided with the design of multiple chamferings on the rotary-cut sword (7), the frictional force between rotary-cut sword (7) and plate can be increased,
Plate is cut convenient for rotary-cut sword (7)；Reach in wooden boards process, fixed purpose is attached to plate.
