Abstract
Schraube (3), die einen Schraubenkopf (31), einen Schaft (32), eine Vielzahl von Gewindezähnen (33) um den Schaft (32) und eine Hilfszone (34) zwischen zwei beliebigen Gewindezähnen (33) umfasst, wobei in der Hilfszone (34) ein Spanabschnitt (341), der mit einem Gewindezahn (33) verbunden ist, und ein Späneableitabschnitt (342) gebildet sind, der sich zwischen dem Spanabschnitt (341) und dem anderen Gewindezahn (33), um die Späne zu ableiten, befindet, wobei der Spanabschnitt (341) eine Vielzahl von Zähnen (3411) bildet, die einen Winkel haben, der anders als der der Gewindezähne (33).Screw (3) comprising a screw head (31), a shaft (32), a plurality of thread teeth (33) around the shaft (32) and an auxiliary zone (34) between any two threaded teeth (33), being in the auxiliary zone (34) a chip portion (341) connected to a thread tooth (33) and a chip discharge portion (342) formed between the chip portion (341) and the other thread tooth (33) to discharge the chips, The chip section (341) forms a plurality of teeth (3411) which have an angle which is different from that of the thread teeth (33).
Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Befestigungselement, insbesondere eine Schraube.The invention relates to a fastening element, in particular a screw.
Stand der TechnikState of the art
Die
In der Praxis weist die Schraube
- 1. da sich die
Rippen 14 von demSchaft 12 nach außen erstrecken, wird der Späneraum durch dieRippen 14 zwischen zweiGewindezähnen 13 verkleinert, wodurch die Befestigungsfestigkeit derSchraube 1 an dem Gegenstand reduziert wird; - 2. wie aus
3 ersichtlich ist, wenn die Späne entlang den Gewindezähnen verschoben werden, werden die Spane von denRippen 14 gesperrt und gesammelt, wodurch die Späne nicht abgeleitet und nur von den hinteren Spänen vorgedruckt werden können, so dass die gesammelten Spane einen Widerstand in der Gegenrichtung für dieGewindezähne 13 derSchraube 1 erzeugen, weshalb der Benutzer mit größerer Kraft dieSchraube 1 drehen muss, was zu einem Bruch der Schraube und einer Reduzierung der Drehgeschwindigkeit führen kann; - 3. wenn die gesammelten Spane eine bestimmte Menge erreicht, wie die Pfeilrichtung zeigt, werden sie von den
Rippen 14 gesperrt und gegen den Gegenstand gedrückt, was zu einem Bruch des Gegenstands führen kann, wodurch dieRippen 14 verkleinert werden müssen, so dass dieRippen 14 die Fasern des Gegenstands, die denSchaft 12 umschlingen, nicht zuverlässig durchschneiden können.
- 1. because the
ribs 14 from theshaft 12 extend to the outside, the chip room is through theribs 14 between twothread teeth 13 reduced, reducing the fastening strength of thescrew 1 is reduced to the object; - 2. like out
3 it can be seen that when the chips are displaced along the thread teeth, the chips are removed from theribs 14 locked and collected, whereby the chips can not be derived and pre-printed only by the back chips, so that the collected chips resistance in the opposite direction for thethread teeth 13 thescrew 1 generate, which is why the user with greater force thescrew 1 turning, which can lead to breakage of the screw and a reduction in the rotational speed; - 3. When the collected chippings reach a certain amount, as indicated by the direction of the arrow, they become off the
ribs 14 locked and pressed against the object, which can lead to breakage of the object, causing theribs 14 need to be scaled down, leaving theribs 14 the fibers of the object, theshaft 12 wrap around, can not cut reliably.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Schraube zu schaffen, die beim Drehen einen Bruch des Gegenstands vermeiden und das Drehmoment reduzieren kann und sich nicht brechen lässt.The invention has for its object to provide a screw that can avoid a breakage of the object during rotation and reduce the torque and can not be broken.
Diese Aufgabe wird durch die erfindungsgemäße Schraube gelöst, die einen Schraubenkopf, einen Schaft, eine Vielzahl von Gewindezähnen um den Schaft und eine Hilfszone zwischen zwei beliebigen Gewindezähnen umfasst, wobei in der Hilfszone ein Spanabschnitt, der mit einem Gewindezahn verbunden ist, und ein Späneableitabschnitt gebildet sind, der sich zwischen dem Spanabschnitt und dem anderen Gewindezahn befindet, wobei der Spanabschnitt eine Vielzahl von Zähnen bildet, die einen Winkel haben, der anders als der der Gewindezähne. Die Zähne in der Hilfszone können die Fasern des Gegenstands, die den Schaft umschlingen, durchschneiden, wodurch der Drehwiderstand des Schaftes verringert wird, so dass das Drehen der Schraube kraftsparend ist. Die durchschnittenen Späne können durch den Spanableitabschnitt abgeleitet werden, wodurch ein Verstopfen der Späne verhindert wird, so dass ein Bruch des Gegenstands und der Schraube vermieden wird.This object is achieved by the screw according to the invention comprising a screw head, a shank, a plurality of thread teeth around the shank and an auxiliary zone between any two thread teeth, wherein formed in the auxiliary zone a chip portion which is connected to a thread tooth, and a chip discharge portion which is located between the chip portion and the other thread tooth, wherein the chip portion forms a plurality of teeth having an angle other than that of the thread teeth. The teeth in the auxiliary zone can cut through the fibers of the article which wrap around the shaft, thereby reducing the rotational resistance of the shaft, so that the rotation of the screw is energy-saving. The cut chips can be discharged through the chip discharge portion, whereby clogging of the chips is prevented, so that breakage of the object and the screw is avoided.

Da der Späneableitabschnitt
Zusammenfassend ist festzustellen, dass die Erfindung zwischen zwei beliebigen Gewindezähnen eine Hilfszone aufweist, in der Zähne vorgesehen sind, die die Fasern um den Schaft durchschneiden und durch den Späneableitabschnitt der Hilfszone ableiten können, wodurch ein Verstopfen der Späne verhindert wird, so dass ein Bruch des Gegenstands und der Schraube vermieden wird und das Drehmoment der Schraube reduziert wird.In summary, it should be noted that between any two thread teeth, the invention has an auxiliary zone in which teeth are provided which can cut the fibers around the shank and divert them through the shaving section of the auxiliary zone, thereby preventing clogging of the shavings, so that breakage of the chips is avoided The object and the screw is avoided and the torque of the screw is reduced.
