Description

Airfoil thrust screw structure

This wing-shaped thrust screw structure is mainly applied to the technology of integrally forming the thrust part of the wing-shaped thrust screw. The thrust part is first formed by stamping a two-wing block, and then the two-wing block The lower edge of the sheet is flattened into two straight parts.

Press, U.S. Patent Certificate Number: 4,764,069 "Anchor for masonry veneer walls" "Stonework Wall Anchor" invention patent, in which: the wall anchor is provided with an internal threaded hole at the tail for fixing a headless screw, The headless screw can be locked and fixed in the internal threaded hole of the wall anchor. The tail of the headless screw is provided with a drill tail or a tapered part, because the outer diameter of the tail end of the wall anchor is larger than that of the headless screw Because of the outer diameter of the tooth, a thrust part is formed to prevent the headless screw from continuing to lock in. However, after making the wall anchor and the headless screw separately, tapping with zinc alloy casting, and finally fixing the headless screw knot in the internal threaded hole of the wall anchor, because the wall anchor is not integrated with the headless screw Molding, complicated processing and high production cost are the existing problems and shortcomings to be solved.

According to another press, the number of the US patent certificate: 6,050,765 "Fastener for logs and fastening technique therefor" invention patent of "Fastener for logs and fastening technique therefor", in which: the fastener is provided with two enlarged parts, the two enlarged parts are mainly For the purpose of hole expansion and chip evacuation, the two enlarged parts do not have a thrust function and cannot prevent the external thread segment from continuing to lock in.

Press again, China Patent Certificate No.: M311788 "Stainless Steel Self-Drilling Screw" new type patent, in which: the stainless steel nail body is provided with an enlarged cap edge at the top, a nail body part at the middle and a drill edge at the bottom, the nail The body part is also provided with a threaded section; the two opposite sides of the nail body part are provided with two convex fins, the two convex fins are in the form of vertical slices; thereby, when the stainless steel self-drilling screw is used for locking The non-metallic plate and the metal skeleton can be used to expand the non-metallic plate by the two convex wing pieces, so that the nail body and the non-metallic plate can maintain a gap, so that the non-metallic plate can be stretched when it shrinks due to heat and cold shrinkage There is space; in addition, the two-convex wing is a stainless steel sheet type, which is extremely hard and brittle, so when the two-convex wing passes through a non-metallic plate and touches the metal skeleton, it will definitely break away from the nail body, making it The effect does not extend to the metal skeleton structure, so as to ensure the stable screwing state of the nail body part and the metal skeleton. However, the role of the two-convex fin is to enlarge the hole, so it does not have the function of thrust, and cannot prevent the thread segment from continuing to lock in.

Press again, the applicant in this case filed an application on September 28, 107, Republic of China, application number: 107134417, certificate number: I664037 "self-tapping screw threading die" invention patent, please refer to the first figure: It is a three-dimensional exploded schematic diagram of Xi-style. The main reason is that one end of the self-tapping screw 40 is provided with a head 41, and the head 41 is provided with a horizontally arranged limiting part 411, and the limiting part 411 is provided with a vertically arranged rotating part 412, and the rotating part 412 As a plate, the rotating part 412 is provided with a penetrating hole 413. The user only needs to insert a driving tool (not shown) on the rotating part 412 to drive and rotate the self-tapping screw 40. The self-tapping The other end of the screw 40 is provided with a drilling portion 42, the drilling portion 42 is formed into a tapered portion 421, the self-tapping screw 40 is interposed between the limiting portion 411 of the head 41 and the drilling portion 42 There is a first shaft 43 and a first Two shafts 44, the second shaft 44 is provided with an outer screw tooth portion 441, which is characterized in that: the tooth is mainly formed by pushing and integrally forming a tooth on the top of the outer screw tooth portion 441 when rubbing teeth A thrust portion 45 is provided at an appropriate position to push the material forming the concave portion 451 downwards out of a convex ring portion 452 so that the outer diameter of the convex ring portion 452 is greater than the outer diameter of the teeth of the outer thread portion 441, by The protruding ring portion 452 prevents the outer screw portion 441 from continuing to lock in. At the same time, a third gasket 50 is provided at the bottom of the protruding ring portion 452, and a third elastic gasket 51 is provided at the bottom of the third gasket 50 By.

However, for the above-mentioned "self-tapping screw rubbing mold" invention patent, in actual operation and application, please refer to the second figure: the lock-in state schematic diagram during the construction of the traditional style. As shown in the third figure: It is a schematic diagram of the completion status during the construction of the Xi-style. Since the thrust portion 45 is integrally formed by pushing, the material forming the recess 451 is pushed down the convex ring portion 452 so that the outer diameter of the convex ring portion 452 is only larger than the outer thread portion 441 The outer diameter of the tooth is a little bit, and the thickness of the protruding ring portion 452 is very thin, causing the user to sleeve a driving tool (not shown) on the rotating portion 412 to drive and rotate the self-tapping screw 40 while using the tip The taper portion 421 is drilled into the cement object 1. When the outer screw portion 441 is locked into the cement object 1, if the self-tapping screw 40 and the third washer 50 are deflected and cannot be corrected, the third The perforation 52 of the gasket 50 and the third elastic gasket 51 will pass through the convex ring portion 452, and may even cause the convex ring portion 452 to be damaged and deformed by the third gasket 50, and then cause the thrust portion 45 to lose its stop The function of blocking the external screw portion 441 to continue to lock in is its existing problems and deficiencies that have yet to be resolved.

The creator is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. In response to the existing problems and deficiencies of the above two US and two Chinese patents, he has actively invested in the spirit of innovation and improvement. Type thrust screw structure.

The technical means applied to solve the new problem and the effect compared with the prior art are: the wing-shaped thrust screw is provided with a head, a first shaft, a second shaft and a drilling portion, the second shaft is provided with There is an external screw portion, the first shaft is provided with a thrust portion corresponding to the external screw portion, and two wings are formed on both sides of the first shaft by integral molding by stamping during the first molding In the second molding, the two wing-shaped baffles are cut into two straight portions corresponding to the outer thread portion. The outer diameter of the thrust portion is larger than the outer diameter of the outer thread portion, with thrust The function of the two straight parts prevents the external screw teeth from continuing to lock in. Since the thrust part is integrally formed, it will not cause the external screw teeth to lock due to defects in processing and assembly processes or improper use by the user If the penetration is too deep, the thrust part breaks when locked, which has an improvement in efficiency and is the main purpose of the achiever.
