Abstract

A wood screw having anticracking and high-speed locking function comprises a screw head for connecting with a fastening tool, a stem body and a screw thread arranged on the stem body, wherein the stem body is extended from the screw head and provided with an axis and a parallel stem body part, the tail end of the parallel stem body part is a gradually-tapered pointed cone part with the tail part being pointed end. Two mutually-symmetrical first groove are arranged on the pointed cone part, the content space is tapered toward the pointed end along axial direction, a second groove is arranged on the parallel stem body part, and the content space is tapered toward the direction of screw head and the pointed end. The utility mode has the advantages that the wood screw can be screwed into the wood without effort as a result of the small friction, the second groove can provide enough content space to hold wood dust produced in the case of screwing the wood screw, thereby making up the insufficiency of the content space of the first groove, reducing the increasing speed of screwing-in torque, enabling the quick locking of the wood screw and the wood block, and effectively preventing the cracking of the wood block.

Description

WOOD SCREWS with anticracking and high speed locking function
Technical field
The utility model is relevant a kind of screw, particularly relevant a kind of WOOD SCREWS.
Background technique
With reference to figure 1, a kind of known WOOD SCREWS 100 comprises a spiral shell head 110 and a body of rod 120.Spiral shell head 110 is in order to join with the locking instrument; 120 of the bodies of rod are extended by spiral shell head 110, and have a parallel bar body portion 124, and the end of this parallel bar body portion 124 is a pointed cone part 122.On parallel bar body portion 124 and pointed cone part 122, be provided with screw thread 130.
Screwing in wooden unit with above-mentioned WOOD SCREWS 100 need not hole on wooden unit in advance, can directly WOOD SCREWS 100 be screwed in the wooden unit.Yet, when WOOD SCREWS 100 is screwed in wooden unit, because of increasing gradually from the frictional force between the parallel body of rod 124 and screw thread 130 and wooden unit, need increasing screw-in torsion, and along with WOOD SCREWS 100 screws in wooden unit, the screw thread 130 cutting wood chips that wooden unit produced can't be discharged smoothly, make the situation that wooden unit splits easily.
With reference to figure 2 and 3 figure, for addressing the above problem, No. the 454834th, TaiWan, China patent announcement, title is " a Screw cutting groove improved structure ", disclosed a kind of screw structure, the pointed cone part 222 of this screw 200 is provided with two corresponding tail cutting slots 240 that extend to parallel bar body portion 224, and its content space makes progress gradually wide shape by the bottom, and the center line of the tail cutting slot 240 and the body of rod 220 forms an angle that tilts.
Above-mentioned screw 200 is threaded in the process of wooden unit, can utilize tail cutting slot 240 to cut off wood fiber, needed torsion when screwing in wooden unit to reduce.Yet the content space of the tail cutting slot 240 of above-mentioned screw 200 is limited can not to hold too many wood fiber, and runs into harder wooden unit, for example when red oak, walnut, easily splits the situation of material, even can't lock.
In addition, with reference to figure 4, No. the 388464th, TaiWan, China patent announcement, title is " but screw structural of fast locking ", also disclosed a kind of screw structure, the pointed cone part 422 of this screw 400 is provided with the tail cutting slot 440 that extends to parallel bar body portion 424, and the center line of itself and the body of rod 420 is formed with an angle that tilts.Also be provided with a profile groove of cutting sth. askew 450 on parallel bar body portion 424, its width dwindles from top to bottom gradually.
Above-mentioned screw 400 is threaded in the process of wooden unit, can utilize tail cutting slot 440 to cut off wood fiber, needed torsion when screwing in wooden unit to reduce.In addition, be located at the profile groove 450 on the parallel bar body portion 424, the wood chip that then can be used to hold in the working angles and produced.Yet, the tail cutting slot 440 of above-mentioned screw 400 still can't hold too many wood fiber with the content space of profile groove 450, cause screw 400 in the process that screws in wooden unit, to meet with bigger frictional force, lock the situation that fracture takes place at profile groove 450 places in the harder wooden unit easily.
Summary of the invention
The utility model is made in view of above-mentioned existing problems, and its purpose is, a kind of WOOD SCREWS with anticracking and high speed locking function is provided.The pointed cone of the utility model WOOD SCREWS part is provided with two first symmetrical grooves that extend to the parallel bar body portion, and also is provided with second groove longitudinally on the parallel bar body portion.
WOOD SCREWS of the present utility model comprises: a spiral shell head and a body of rod and be located at screw thread on the body of rod, the spiral shell head is in order to join with the locking instrument, so that WOOD SCREWS is screwed in the wooden unit.Extend the body of rod by the spiral shell head, this body of rod has an axis and a parallel bar body portion, and the end of this parallel bar body portion is tapered pointed cone part, and the end of this pointed cone part is most advanced and sophisticated.The body of rod is provided with screw thread and can meshes with wooden unit, so that the stretching resistance that prevents that WOOD SCREWS from extracting to be provided.The pointed cone part is provided with two first grooves that are in symmetry, and towards most advanced and sophisticated convergent, partly locate by the pointed cone that is tapered to tip or close tip at last along axial direction for the content space of this first groove.First groove has a diapire, the angle of itself and the parallel axes or the non-zero that tilts.Be provided with second groove longitudinally on the parallel bar body portion, the content space of this second groove is towards spiral shell head and tip direction convergent, most advanced and sophisticated apart from the nearest axial distance of second groove less than or be not less than most advanced and sophisticated apart from first groove axial distance farthest.
The advantage of the utility model WOOD SCREWS is, because partly having two first symmetrical grooves at its pointed cone can be used to cut off wood fiber, prevent that wooden unit from breaking in sealed process, and can make WOOD SCREWS in screwing in the process of wooden unit, suffer from less frictional force and need not effort and screw in.In addition, on the parallel bar body portion, be provided with produce when second groove can provide enough content space to screw in WOOD SCREWS to hold wood chip, remedy the deficiency of the first groove content space of two symmetries, can reduce and screw in advancing the speed of torsion, make WOOD SCREWS and wooden unit fast locking, and can effectively prevent breaking of wooden unit, when running into harder wooden unit, also can lock smoothly.
