Abstract
The invention publicizes a screw that comprises a head, a rod, a tip and multi continuous coiling screw threads formed on the rod. A protruding cutting section is set on the threaded front facing the tip on the rod to allow the front successfully finishing the first stage of process for cutting and quick chip removal while screwing to the working piece. An inward concave cutting section is set on the threaded back to allow the back part inserted into the working piece with smooth completion of the second stage process of cutting and quick chip removal. Apart from that, a cutting groove can be set at the tip of the screw or set several cutting teeth outside of the thread to enhance the ability of quick screwing the tip of the screw. With the above design, a screw fastening device is formed with the features of laborsaving cutting, quick chip removal and chip collecting.
Description
Technical field
The present invention relates to a kind of screw, relate in particular to a kind of bar portion and be positioned at and have evagination cutting portion, indent cutting portion between screw thread respectively, and make this screw form a kind of solid product of spiral shell with laborsaving cutting and multi-efficiencies such as quick chip removal and crumb loading at screw.
Background technique
Progress along with each industrial technology, structural design for present screw, from only being simple locking, and then develop into the working efficiency of paying attention in the locking process, and the integrity of destrudo locking object not, can be by the present invention designed in the early time and through application check and approve and disclosed TaiWan, China patent gazette on No. 556784 " screw improvement ", No. 289405 novel patent cases such as " integrating the sealed screw of stablizing laborsaving quick multifunctional " is as the main representative of screw, can know and learn that this two case is not only fully improved the deficiency of the simple screw that locks of tradition, and in actual use, reach the designed screw of each case really and have the purpose of essence progress.
Yet the present invention still felt to have to make its more perfect progressive space for " screw improvement ", " integrating the sealed screw of stablizing laborsaving quick multifunctional " of above-mentioned two cases; For example, the novel patent case of No. 556784 " screw improvement ", though its bar portion has the structure function of cutting crumb loading, but coping screw nail begins to screw in as objects such as timber when interior, be subjected to object and organize the obstruction of hardness, so the staff still needs the operation of the suitable application of force, cause in the locking operation, still have the disappearance that is screwed into operating difficulties; And for example, No. 289405 novel patent cases such as " integrating the sealed screw of stablizing laborsaving quick multifunctional ", though its bar portion has the structure function of cutting chip removal, but in bar portion with the stage casing that screws in object between back segment, because of bits shape thing can't be discharged, and pushing tow is to the object surrounding tissue laterally by bar portion, so that object has outside expansion, even heavy damage object outward appearance.
The present invention has the novel patent case of stating both parties in a lawsuit in view of this, still have and to carry out Luo Guzhong, multi-efficiencies such as cutting, chip removal and crumb loading are arranged simultaneously, there is not satisfactory part, so adhere to the professional experiences of being engaged in this technical field for many years, be the idea of asking the product lean to look for novelty, improved innovation at the deficiency of above-mentioned screw especially, in this, finally successfully develop a kind of really can be when locking with screw, the function that has quick cutting, chip removal and a crumb loading by its structure is gathered the design in one, to reach the value of this industry.
Summary of the invention
The objective of the invention is to by a kind of screw is provided, in its bar portion, be formed with the plural screw thread that coils continuously with helical; Wherein this bar portion is provided with the evagination cutting portion at the leading portion place that has screw thread towards the tip, screw in the object for being in for its leading portion, to finish the phase I work of cutting and quick chip removal smoothly, and this bar portion is provided with the indent cutting portion at the back segment place that has screw thread towards head, for in its back segment place Import Object, finished the work of the second stage of the quick crumb loading of cutting smoothly; So that this screw in the process that locks, reaches laborsaving, the smooth and multi-efficiencies such as quick chip removal and crumb loading of cutting.
Another object of the present invention is to, for above-mentioned screw, not only have beyond the design of evagination cutting portion, indent cutting portion, more can be positioned at the place, tip and can be provided with cutting slot in screw, or the screw thread outside that is positioned at this place is provided with several cutting teeths, with this, has the miscellaneous function that the tip that strengthens screw screws in fast, effectively improve the real benefit of this screw integral body, so that this screw forms a kind of solid product of spiral shell of innovating practicality and having enhancement essence effect.
The present invention realizes by the following technical solutions:
A kind of screw is to include head, bar portion, tip, and is positioned at a plurality of screw threads that are formed with in the bar portion with the continuous coiling of helical; This bar portion is provided with the evagination cutting portion at the leading portion place towards the tip, and this bar portion is provided with at the back segment place that has screw thread towards head for this place and enters indent cutting portion in the object.
Aforesaid evagination cutting portion can be the rib-like of the evagination of falling V.
Aforesaid evagination cutting portion can be the rib-like of the oblique evagination of falling V.
Aforesaid evagination cutting portion can be built in the bar portion in being oblique between screw thread and the screw thread.
Aforesaid indent cutting portion can be the ditch strip of V word indent.
Aforesaid indent cutting portion can be the ditch strip of oblique V word indent.
Aforesaid indent cutting portion can be built in the bar portion in being oblique between screw thread and the screw thread.
Aforesaid screw is positioned at the place, tip can be provided with cutting slot.
The screw thread outside that aforesaid screw is positioned at the place, tip is provided with several cutting teeths.
The present invention compared with prior art has remarkable advantages and beneficial effect:
Because a kind of screw of the present invention, be provided with the evagination cutting portion in its bar portion at leading portion place towards the tip, and be provided with at the back segment place that has screw thread towards head for this place in this bar portion and enter indent cutting portion in the object, therefore make in its back segment place Import Object, finished the work of the quick crumb loading of cutting smoothly; So that this screw in the process that locks, cuts laborsaving, smooth and multi-efficiencies such as quick chip removal and crumb loading, effectively raise the utilization efficiency of this screw.
