Specific embodiment
Below with reference to examples and drawings, the technical solution of the utility model is further elaborated.
As shown in Figure 1 to Figure 3, this hinge screw includes:
Bar portion 20 is surrounded with two screw threads thereon, and two screw threads are arranged in double-helix, wherein a screw thread is to cut
Screw thread 21 is cut, another screw thread is complementary screw-threads 22, and the outer diameter of screw cutting 21 is greater than the outer diameter of complementary screw-threads 22, and is cutting
Multiple row notch 23 is offered on screw thread 21；
Head 10 is installed in 20 one end of bar portion, and head 10 is in pyramidal setting, and end face of the head 10 far from bar portion 20 is straight
Diameter is greater than head 10 close to the end face diameter of bar portion 20.
The screw that existing mating hinge uses is arranged to greatly single thread structure, for cutting speed when cutting timber
Slowly, incision effect is undesirable, is unfavorable for cutting hard timber etc., and common screw is often made of ferrous material, with wood
It gets rusty easily, reduces the service life after moisture in door；In addition, the chip of generation cannot be timely when screw squeezes into timber
Discharge, rests on inside timber and is centered around around screw, is easy squeeze crack wood substrates, is unfavorable for connecting between screw and timber steady
It is fixed, it is easy to influence the normal mounting of hinge, using effect is poor.
For this purpose, the utility model devises a kind of hinge screw, screw is enhanced by the setting of double helix screw thread and is screwed into wood
The intensity of door etc., quickly cuts timber；Notch 23 is opened up on screw cutting 21 simultaneously, is conducive to chip discharge.
Specifically, the head 10 of hinge screw is tack setting herein, and head 10 is in pyramidal setting, and frustum is compared with facet
Long-pending end face is connect with bar portion 20, and preferably head 10 and bar portion 20 are integrally formed setting, and head 10 is close to the end face of bar portion 20
Diameter is equal with the diameter of bar portion 20, and transition is gentle in structure, and intensity is high.
Two screw threads of double-helix, respectively screw cutting 21, complementary screw-threads 22, and this reality is presented in setting in bar portion 20
The outer diameter for applying preferred screw cutting 21 in example is greater than the outer diameter of complementary screw-threads 22, and the state of height tooth, incision is presented in two screw threads
Speed is fast, and pulling capacity is high, is respectively suitable for the timber installation of hardwood, cork etc., easy for installation and good fixing effect.
Preferably, each column notch 23 is uniformly distributed around screw cutting 21 in the shape of a spiral.
Herein around multiple row notch 23 is opened up preferably on screw cutting 21, specially two are arranged, and two Lieque mouths 23 are same
Double-spiral structure setting is presented, is uniformly distributed around screw cutting 21, on the one hand the setting of notch 23 is convenient for screw to cut timber,
On the other hand screw can be cut chip discharge caused by timber, to reduce swelling stress, using effect is good.
Further, bar portion 20 offers tail cutting slot 24 far from the one end on head 10, and the width of tail cutting slot 24 is towards head
10 direction of portion is gradually increased.The setting of tail cutting slot 24 is further convenient for screw to be screwed into the components such as timber, improves the cutting energy of screw
Power.
Wherein the width of tail cutting slot 24 is gradually increased by bar portion 20 to 10 direction of head, is conducive to production when screw incision timber
Raw cutting discharges, and quickly cuts timber convenient for screw.In addition, the chip that part can not be discharged immediately can also accommodate
In tail cutting slot 24, chip is avoided excessively and influences the connective stability between screw and timber.
Preferably, multiple fins 11 are provided on 10 outer peripheral surface of head, each fin 11 is in gradually to open around 10 axial line of head
Formula distribution, and the arc-shaped shape setting of each fin 11.
The fin 11 of retaining is set preferably on the frustum on head 10 in the present embodiment, and is uniformly divided on frustum week side
Cloth, herein on the one hand preferred each fin 11 can be improved between screw and timber along involute around the side EDS maps of frustum
Frictional force, the phenomenon that avoiding screw from retracting；On the other hand be conducive to contact between screw head 10 and timber closely, mention
High bonding strength.
Further, head 10 is recessed inwardly to form the groove 12 of class plum blossom-shaped far from the end face of bar portion 20.
The setting of groove 12 is convenient for inserting screws into timber using plum blossom-shaped screwdriver etc., the groove 12 of plum blossom-shaped setting with
The screwdriver to match is used cooperatively, and compared to traditional cross-shaped groove structure, driving force is bigger and driving is steady, so that installation is flat
Surely, the surface layer of survivable screw head 10 and structure and when being screwed into screw avoid screw damage from getting rusty.
In addition, groove 12 is arranged in plum blossom-shaped, moreover it is possible to can be improved the aesthetics of screw.
The setting of this hinge bolt structure rationally, the intensity of timber etc. is screwed by the setting enhancing screw of double helix screw thread,
Quickly incision timber；Notch 23 is opened up on screw cutting 21 simultaneously, is conducive to chip discharge；In addition, the setting of tail cutting slot 24
It further can be quickly screwed timber convenient for screw, and certain chip can be accommodated, prevent squeeze crack timber, and convenience is installed.
Described herein is only preferred embodiments of the present invention, but the protection scope of the utility model is not
It is confined to this.The modify or supplement or adopt that the utility model those skilled in the art carries out described specific embodiment
