Description
Technical field
The utility model is related to build the finishing field of furniture, and in particular to a kind of tapping screw.
Background technology
Tapping screw, the entitled Self-tapping Screw of English be in the prebored hole of metal or nonmetallic materials voluntarily
Attacking the one kind for drilling out negative thread joined together has threaded fasteners.Tapping screw is chiefly used between thin metallic plate (steel plate, saw plate etc.)
Connection.When connection, thread Pilot hole first is made to connected piece, then tapping screw is screwed into the thread Pilot hole of connected piece.
It, can be in the thread Pilot hole of connected piece in tapping since the thread surface of tapping screw has higher hardness (>=45HRC)
Screw thread, to form connection.
Tapping screw is often threaded onto on the mounting material that timber is matrix, especially very extensive in furniture sector application, mesh
It is particieboard (Particle board) to have in preceding furniture greatly, bagasse board is called, by timber or other wood fibres
Particle made of cellulosic material applies the wood-based plate composed under heating power and pressure effect after adhesive, also known as flakeboard.Mainly
For Furniture manufacture and building industry and train, automobile bodies manufacture.Because wood shavings harden structure is relatively uniform, processing performance is good,
It can be processed into the plank of large format as needed, be the preferable raw material of furniture for making different size, pattern.Manufactured goods are dug
Card need not be dried again, can directly use, and sound-absorbing and sound insulation value are also fine.But it also has the shortcomings that its is intrinsic, because
For edge roughness, it is easy moisture absorption, so just seeming especially important with the edge sealing of furniture technique of particle boards to manufacturing.Additionally, due to wood shavings
Plate volume is larger, with its Hepplewhite, for other planks, also than heavier.
But particieboard can destroy the glued construction of its own when tapping screw is screwed into, therefore can cause to be screwed into a mechanics
Reduced performance.
Utility model content
Based on the above issues, the utility model aim can melt included hot melt after being to provide a kind of installation by heating
Glue, to realize the tapping screw mutually glued with fixture.
In view of the above problems, providing following technical solution：A kind of tapping screw, including shank of screw, the shank of screw one
End is equipped with nut, and the shank of screw is equipped with taper from tap holder relative to one end of nut, and the shank of screw surface is along its axial direction side
To if arterial highway melten gel slot is uniformly offered, hot melt adhesive is filled in the colloidal sol slot；The shank of screw and taper self tapping head surface
Equipped with tapping screw thread.
In above structure, by the way that melten gel slot is arranged on shank of screw surface, then hot melt adhesive is filled inside it, after it is screwed into
Can carry out heating to nut by electric iron makes its melting hot melt adhesive realize that gluing is fixed, improves fix tightly soundness.
The utility model is further arranged to, and melten gel slot one end approaches nut, and the melten gel slot flute length is less than screw
Pole length.
In above structure, since tapping screw thread needs to squeeze into material, melten gel slot from tap holder by taper when being screwed into
It is shorter in length than screw pole length, the threaded hole of tapping is supported using the diameter of shank of screw itself, avoids being screwed into
The hot melt adhesive being expressed in journey in melten gel slot causes hot melt adhesive to be lost or be detached from melten gel slot.
The utility model is further arranged to, and the tapping screw thread is disconnected when being equipped with the surface of melten gel slot by shank of screw
It opens.
In above structure, shank of screw just starts to open up melten gel slot after processing tapping screw thread, therefore can cut off melten gel slot
The tapping screw thread of top, convenient for next procedure towards filling hot melt adhesive in melten gel slot.
The beneficial effects of the utility model：Nut can be heated by electric iron after installation, its heat is made to conduct to shank of screw
Included hot melt adhesive is melted with this, and, raising fix tightly soundness mutually glued with fixture is realized by hot melt adhesive, especially for
The damage of particieboard inside glued construction caused after being screwed into tapping screw, has positive repair.
Description of the drawings
Fig. 1 is the complete section structural schematic diagram of the utility model；
Fig. 2 is the A of the utility model to section structure diagram.
Figure label meaning：10- shanks of screw；11- nuts；12- tapers are from tap holder；13- melten gel slots；14- hot melt adhesive；15-
Tapping screw thread.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
With reference to figure 1 and Fig. 2, a kind of tapping screw as shown in Figures 1 and 2, including shank of screw 10, the shank of screw 10 1
End is equipped with nut 11, and the shank of screw 10 is equipped with taper from tap holder 12,10 surface of the shank of screw relative to one end of nut 11
If uniformly offering arterial highway melten gel slot 13 along its axial direction, hot melt adhesive 14 is filled in the colloidal sol slot 13；The shank of screw
10 and taper from 12 surface of tap holder be equipped with tapping screw thread 15.
In above structure, by the way that melten gel slot 13, then filling hot melt adhesive 14 inside it is arranged on 10 surface of shank of screw, when it
Can carry out heating to nut 11 by electric iron after being screwed into makes its melting hot melt adhesive 14 realize glued fixation, improves fixation
Degree.
In the present embodiment, described 13 one end of melten gel slot approaches nut 11, and 13 flute length of melten gel slot is grown less than shank of screw 10
Degree.
In above structure, since tapping screw thread 15 needs to squeeze into material from tap holder 12 by taper when being screwed into, melt
Glue groove 13 is shorter in length than 10 length of shank of screw, and using shank of screw 10, the diameter of itself is supported the threaded hole of tapping, keeps away
The hot melt adhesive 14 for exempting to be expressed in melten gel slot 13 during being screwed into causes hot melt adhesive 14 to be lost or be detached from melten gel slot 13.
In the present embodiment, the tapping screw thread 15 is disconnected when being equipped with the surface of melten gel slot 13 by shank of screw 10.
In above structure, shank of screw 10 just starts to open up melten gel slot 13 after processing tapping screw thread 15, therefore can cut off
The part tapping screw thread 15 of 13 top of melten gel slot fills hot melt adhesive 14 convenient for next procedure towards melten gel slot 13 is interior.
The beneficial effects of the utility model：Nut 11 can be heated by electric iron after installation, its heat is made to conduct to screw
Bar 10 melts included hot melt adhesive 14 with this, and, raising fix tightly soundness mutually glued with fixture is realized by hot melt adhesive 14, special
It is not the damage of the inside glued construction caused after being screwed into tapping screw for particieboard, there is positive repair.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
