Description
本新型是有關於一種螺絲，特別是指一種用於鎖入水泥或混凝土材質之被鎖合物中的水泥螺絲The present invention relates to a screw, in particular to a cement screw for locking into a cement or concrete material.
為了達到最佳的鎖固效果，螺絲之形態需要針對不同材質及特性的被鎖合物進行設計，其中，用於鎖固水泥或混凝土材質的水泥螺絲為了達到更好的鎖固效果，其螺紋之設計常需要與一般螺絲之螺紋有所區別，以便能適應水泥或混凝土硬度較高之材質特性。In order to achieve the best locking effect, the shape of the screw needs to be designed for the lock compound of different materials and characteristics. Among them, the cement screw used for locking cement or concrete material has a thread for better locking effect. The design often needs to be different from the thread of a general screw in order to adapt to the material properties of cement or concrete with higher hardness.
參閱圖1，為傳統使用之水泥螺絲1。該水泥螺絲1包含一螺頭11、一連接自該螺頭11並具有一遠離該螺頭11之***端121的螺桿12、一環繞於該螺桿12之第一螺紋13，及一環繞於該螺桿12且與該第一螺紋13相間隔之第二螺紋14。其中，該第二螺紋14之外徑是小於該第一螺紋13之外徑。Referring to Figure 1, the cement screw 1 is conventionally used. The cement screw 1 includes a screw head 11 , a screw 12 connected from the screw head 11 and having an insertion end 121 away from the screw head 11 , a first thread 13 surrounding the screw 12 , and a surrounding A screw 12 and a second thread 14 spaced from the first thread 13 . The outer diameter of the second thread 14 is smaller than the outer diameter of the first thread 13 .
當習知水泥螺絲1在鎖固一水泥或混凝土材質之被鎖合物(圖未示)時，該第一螺紋13及該第二螺紋14可分別對該被鎖合物形成新的切入面，使得習知水泥螺絲1與該被鎖合物間的接觸面積增加，進而提高鎖固能力。此 外，透過外徑較小之第二螺紋14的設計，能在習知水泥螺絲1鎖固該被鎖合物的過程中做為緩衝區，讓該習知水泥螺絲1的旋入扭力可以降低，加快鎖固的速度。When the conventional cement screw 1 locks a cement or concrete material (not shown), the first thread 13 and the second thread 14 respectively form a new cut surface for the interlocking compound. The contact area between the conventional cement screw 1 and the interlocked compound is increased, thereby improving the locking ability. this In addition, the design of the second thread 14 having a smaller outer diameter can be used as a buffer in the process of locking the lock compound by the conventional cement screw 1, so that the screwing torque of the conventional cement screw 1 can be reduced. Speed up the locking.
參閱圖2，為中華民國公告第M385613號「螺絲」新型專利，其所揭露之螺絲2包含一螺頭21、一連接自該螺頭21並具有一遠離該螺頭21之***端221的螺桿22、環繞於該螺桿22且彼此相間隔之一第一螺紋23、一第二螺紋24，及一第三螺紋25。其中，該第一螺紋23具有多數個螺牙231，且該第二螺紋24之外徑寬度是小於該第一螺紋23之外徑寬度，並大於該第三螺紋25之外徑寬度。藉此設計，不但能達到與習知水泥螺絲1相同之功效，更以該第二螺紋24及該第三螺紋25的雙重設置提升了緩衝效果。Referring to Fig. 2, there is a new patent of "Mount Screw" No. M385613 of the Republic of China. The screw 2 disclosed therein comprises a screw head 21, a screw connected from the screw head 21 and having a insertion end 221 away from the screw head 21. 22. A first thread 23, a second thread 24, and a third thread 25 that surround the screw 22 and are spaced apart from each other. The first thread 23 has a plurality of threads 231, and the outer diameter of the second thread 24 is smaller than the outer diameter of the first thread 23 and larger than the outer diameter of the third thread 25. With this design, not only can the same effect as the conventional cement screw 1 be achieved, but the double setting of the second thread 24 and the third thread 25 enhances the cushioning effect.
然而，參閱圖1及圖2，無論是習知水泥螺絲1或習知螺絲2，在鎖固混凝土或水泥材質之被鎖合物時，由於該***端121、221受到的摩擦阻力過大，會導致習知水泥螺絲1或該螺絲2在施工時因平衡不佳而產生鎖固方向歪斜的問題。此外，在鎖固的過程中，所述第一螺紋13、23、所述第二螺紋14、24，及該第三螺紋25的形狀設計，會使得該水泥螺絲1或該螺絲2隨著鎖固深度之增加而需要更大的旋入扭力才能克服越來越大之摩擦力，導致作業費時費力，亦不能克服鎖固過程中被鎖合物碎裂產生的碎屑無法被排除的問題。However, referring to FIG. 1 and FIG. 2, whether the conventional cement screw 1 or the conventional screw 2 is locked in the concrete or cement material, since the frictional resistance of the insertion ends 121 and 221 is too large, This causes the conventional cement screw 1 or the screw 2 to have a problem of skewing in the locking direction due to poor balance during construction. In addition, during the locking process, the first thread 13, 23, the second thread 14, 24, and the third thread 25 are shaped to make the cement screw 1 or the screw 2 follow the lock. The increase in solid depth requires greater screwing torque to overcome the increasing friction, resulting in time-consuming and laborious operations, and cannot overcome the problem that debris generated by the cracking of the lock compound during the locking process cannot be eliminated.
因此，本新型之目的，即在提供一種在鎖入時可以維持平衡，並可增進作業效率之水泥螺絲。Therefore, the object of the present invention is to provide a cement screw which can maintain balance during locking and can improve work efficiency.

And a second tooth surface that intersects the first tooth surface and faces one side of the flat cone portion, and the first tooth surface extends outward from the shaft portion in a curved shape. In addition, the angle between the second tooth surface and a plane perpendicular to the central axis of the screw is smaller than the angle between the first tooth surface and the plane perpendicular to the central axis of the screw.
該第二螺紋單元包括多數個螺旋設於該螺桿上並介於該螺頭及該平錐部間之第二螺牙，且該等第二螺牙是與該第一螺牙間隔設置。該引導單元則包括至少一設置於該平錐部表面並向該桿身部方向延伸之引導螺牙，該引導螺牙是位於該第一螺牙單元及該第二螺牙單元之下方。The second threaded unit includes a plurality of second threaded screws disposed on the screw and interposed between the screw head and the flat taper portion, and the second threaded teeth are spaced apart from the first thread. The guiding unit includes at least one guiding screw disposed on the surface of the flat cone portion and extending in the direction of the shaft portion, and the guiding screw is located below the first screw unit and the second screw unit.
本新型之功效在於，藉由該第二牙面與垂直該螺桿中心軸線的平面所相夾的夾角小於該第一牙面與該垂直該螺桿中心軸線之該平面所相夾的夾角的設計，輔以該 第一牙面呈弧面狀的態樣，使該水泥螺絲能輕易地切削被鎖合物，並透過該引導單元的設置而能於鎖固過程中順利排屑。The effect of the present invention is that the angle between the second tooth surface and the plane perpendicular to the central axis of the screw is smaller than the angle between the first tooth surface and the plane perpendicular to the central axis of the screw.

該第二螺紋單元34包括二螺旋環設於該螺桿32上且介於該螺頭31之頭部311及該平錐部322間之第二 螺牙341，且該等第二螺牙341是與該第一螺牙331間隔設置。此外，該等第二螺牙341之牙底徑D2是大於該第一螺牙331之牙底徑D1。The second thread unit 34 includes a second spiral ring disposed on the screw 32 and interposed between the head 311 of the screw head 31 and the flat cone portion 322. The thread 341 is disposed, and the second thread 341 is spaced apart from the first thread 331. In addition, the bottom diameter D2 of the second thread 341 is greater than the bottom diameter D1 of the first thread 331.
該引導單元35包括三個對稱地設置於該平錐部322表面並向該桿身部321方向延伸之引導螺牙351，該等引導螺牙351是位於該第一螺紋單元33及該第二螺紋單元34之下方。需特別說明的是，該等第二螺牙341的外徑是小於該第一螺牙331的外徑，且大於或等於該等引導螺牙351之外徑。此外，該第一螺牙331的導程角(lead angle)A是小於該等引導螺牙351的導程角C，且等於該等第二螺牙341的導程角B。The guiding unit 35 includes three guiding threads 351 symmetrically disposed on the surface of the flat tapered portion 322 and extending toward the shaft portion 321 .

It should be noted that the outer diameter of the second thread 341 is smaller than the outer diameter of the first thread 331 and greater than or equal to the outer diameter of the guiding threads 351. In addition, the lead angle A of the first thread 331 is smaller than the lead angle C of the guiding threads 351 and is equal to the lead angle B of the second threads 341.
續參閱圖3及圖4，使用時，使用者會先在該被鎖合物上預鑽一預鑽孔(圖未示)，並將一鎖固工具(圖未示)與該螺頭31相接，使本新型之水泥螺絲3的平錐部322即可自該預鑽孔漸次向下鎖固該被鎖合物，並透過該等引導螺牙351的引導，迅速地旋入該被鎖合物中。需特別說明的是，該等引導螺牙351之數目在本較佳實施例中是以三個做說明，但並不以此為限，也可以是僅具有一個引導螺牙351。但當引導螺牙351的數目為三時，在水泥螺絲3之平錐部322與該被鎖合物相交接的任一個橫切面上，該等引導螺牙351共可對該被鎖合物產生三個施力點，並由於三點可決定一平面，使該水泥螺絲3的平錐部322在鎖固的過程中可依照預期的方向穩定的形成多個彼此平行的切面，進而能確保該水泥螺絲3在鎖固的過程中不會因為 施力點的偏移而歪斜。Referring to FIG. 3 and FIG. 4, in use, the user pre-drills a pre-drilled hole (not shown) on the interlocking compound, and a locking tool (not shown) and the screw head 31. In connection, the flat taper portion 322 of the cement screw 3 of the present invention can gradually lock the lock compound downward from the pre-drilled hole, and can be quickly screwed into the quilt through the guiding of the guiding screw 351. In the lock compound. It should be noted that the number of the guiding threads 351 is described by three in the preferred embodiment, but not limited thereto, and only one guiding screw 351 may be provided. However, when the number of the guiding threads 351 is three, the guiding threads 351 can be the same in the cross section of the flat taper portion 322 of the cement screw 3 and the interlocking compound. Three force application points are generated, and a flat surface is determined by three points, so that the flat taper portion 322 of the cement screw 3 can stably form a plurality of parallel cutting surfaces in a desired direction during the locking process, thereby ensuring a plurality of mutually parallel cutting surfaces. The cement screw 3 will not be in the process of locking The offset of the force point is skewed.
此外，由於該等引導螺牙351的設置，使該水泥螺絲3在沿該預鑽孔向下鎖固時，該等引導螺牙351還能繼續切削擴孔，使該預鑽孔的寬度些微變大，讓之後位於該桿身部321上的第一螺紋單元33及第二螺紋單元34能更容易鎖入該被鎖合物中，加快了本新型之水泥螺絲3的鎖合速度。In addition, due to the arrangement of the guiding threads 351, when the cement screw 3 is locked downward along the pre-drilled hole, the guiding threads 351 can continue to cut and ream, so that the width of the pre-drilling hole is slightly When it is enlarged, the first thread unit 33 and the second thread unit 34 which are later located on the shaft portion 321 can be more easily locked into the interlocking compound, which accelerates the locking speed of the cement screw 3 of the present invention.
此外，由於該被鎖合物的材質特性，會讓使用者在對該被鎖合物進行預鑽孔的鑽設步驟時，在預鑽孔中留下大量的積屑，如果不清除積屑，則會嚴重地影響鎖固的速度及效果。而在本新型之水泥螺絲3鎖固的過程中，該第一螺紋單元33及該第二螺紋單元34鎖入該被鎖合物前會先有該引導單元35做為前導，因此留於該預鑽孔中之積屑可藉由該等引導螺牙351的設計順利排出，使積屑不再影響後續的鎖固效果及鎖固速度。In addition, due to the material properties of the locked compound, the user may leave a large amount of accumulated debris in the pre-drilled hole during the drilling step of pre-drilling the locked compound, if the accumulated debris is not removed. , it will seriously affect the speed and effect of the lock. In the process of locking the cement screw 3 of the present invention, the first thread unit 33 and the second thread unit 34 are pre-guided before being locked into the lock compound, so The accumulated debris in the pre-drilled hole can be smoothly discharged by the design of the guiding screw 351, so that the accumulated debris no longer affects the subsequent locking effect and the locking speed.
而當該等第二螺牙341及該第一螺牙331開始鎖固於該被鎖合物中時，由於該等第二螺牙341之外徑小於該第一螺牙331之外徑，因此能對該被鎖合物產生不同於該第一螺牙331之切入面，進而增加與該被鎖合物之間的接觸面積並提升鎖固效果，且同時為該水泥螺絲3提供介於該第一螺牙331之螺距間的緩衝區，降低鎖固過程中產生的摩擦力並減少旋入扭力，使鎖固的過程更加順暢。 藉由上述設計，本新型水泥螺絲3在實際使用時具有下列優點：When the second screw 341 and the first screw 331 start to be locked in the interlocking compound, since the outer diameter of the second screw 341 is smaller than the outer diameter of the first screw 331, Therefore, the cut-in surface different from the first screw 331 can be generated for the lock compound, thereby increasing the contact area with the lock compound and improving the locking effect, and at the same time providing the cement screw 3 with The buffer between the pitches of the first thread 331 reduces the friction generated during the locking process and reduces the screwing torque, so that the locking process is smoother. With the above design, the new cement screw 3 has the following advantages in practical use:
(1)利於切削硬質水泥：(1) Conducive to cutting hard cement:
藉由該第二牙面339與垂直該中心軸線L的平面P所相夾的夾角α小於該第一牙面338與該垂直該中心軸線L之平面P所相夾的夾角β的設計，以及呈弧面狀之第一牙面338，使本新型之水泥螺絲3易於切削硬質水泥，並能避免鎖入時造成該第一螺牙331及該等第二螺牙341周邊的水泥碎裂。The angle α between the second tooth surface 339 and the plane P perpendicular to the central axis L is smaller than the angle β between the first tooth surface 338 and the plane P perpendicular to the central axis L, and The first tooth surface 338 having a curved surface makes the cement screw 3 of the present invention easy to cut hard cement, and can prevent the first screw 331 and the cement around the second screw 341 from being broken when locked.
(2)增加鎖固速度：(2) Increase the locking speed:
由於該等引導螺牙351的導程角C的角度較大，且該等引導螺牙351在鎖固的過程中可持續對該預鑽孔進行切削及擴孔，因此能降低本新型之水泥螺絲3的旋入扭力，引導該水泥螺絲3迅速的鎖入該被鎖合物中。此外，透過該等第二螺牙341形成之緩衝區，同樣可達到降低旋入扭力而提升鎖固速度的功效。Since the angles of the lead angles C of the guiding threads 351 are large, and the guiding threads 351 can continuously cut and ream the pre-drilled holes during the locking process, the cement of the present invention can be reduced. The screwing torque of the screw 3 guides the cement screw 3 to quickly lock into the interlocking compound. In addition, the buffer formed by the second screw 341 can also achieve the effect of reducing the screwing torque and increasing the locking speed.
(3)維持平衡：(3) Maintain balance:
由於該等引導螺牙351是對稱地設置於該平錐部322及該桿身部321與該平錐部322相連之一段上，因此能於鎖固過程中以三點定位的方式不斷地於該被鎖合物與該水泥螺絲3間產生定向的切面，使該水泥螺絲3之螺桿32可維持平衡地依使 用者預定的方向穩固地鎖入，不會產生鎖固方向歪斜的問題。Since the guiding screw 351 is symmetrically disposed on the flat taper portion 322 and the shaft portion 321 is connected to the flat taper portion 322, it can be continuously positioned in a three-point manner during the locking process. The locked compound and the cement screw 3 produce an oriented cut surface, so that the screw 32 of the cement screw 3 can maintain a balanced balance. The user's predetermined direction is firmly locked, and there is no problem that the locking direction is skewed.
(4)增加鎖固能力：(4) Increase the locking capacity:
本新型之水泥螺絲3於鎖固過程中，透過該等第二螺牙341不同於該第一螺牙331之外徑，對該被鎖合物形成另一切入面，使該水泥螺絲3與該被鎖合物間的咬合面積增加，進而提高鎖固能力。此外，透過該第一牙面338是呈弧面狀之設計，亦能增加該水泥螺絲3的承載力及抗拉力。In the locking process of the present invention, the second screw 341 is different from the outer diameter of the first screw 331 by the second screw 341 to form another cutting surface of the locked compound, so that the cement screw 3 and the cement screw 3 The occlusal area between the interlocked compounds is increased, thereby improving the locking ability. In addition, the first tooth surface 338 has a curved surface design, and the bearing capacity and tensile strength of the cement screw 3 can also be increased.
(5)有效排除積屑：(5) Effectively eliminate accumulated debris:
由於該被鎖合物的材質為水泥或混凝土材質，因此在預鑽孔中會留有許多積屑。而本新型之水泥螺絲3則可藉由該等引導螺牙351的設計，使水泥螺絲3在鎖固的過程中能將預鑽孔中的積屑順利沿該等引導螺牙351排出。Since the material of the lock compound is made of cement or concrete, many accumulated chips remain in the pre-drilled hole. The cement screw 3 of the present invention can be designed such that the cement screw 3 can smoothly discharge the accumulated debris in the pre-drilled hole along the guiding screw 351 during the locking process.
(6)增加拉出力：(6) Increase the pull-out force:
由於該等第二螺牙341之牙底徑D2是大於該第一螺牙331之牙底徑D1，使得本新型水泥螺絲3鎖入被鎖合物中後，藉由螺旋間隔的該等第二螺牙341與該第一螺牙331之牙底徑D2、D1的不同，增進本新型水泥螺絲3與被鎖合物(例如：混凝土)的卡掣效果，讓該水泥螺絲3被拉出之阻 力增加，使得本新型之水泥螺絲3不易脫落或鬆開。Since the bottom diameter D2 of the second thread 341 is larger than the bottom diameter D1 of the first thread 331, the cement screw 3 of the present type is locked into the locked compound, and the spiral spacing is used. The difference between the second screw 341 and the bottom diameter D2 and D1 of the first screw 331 improves the clamping effect of the cement screw 3 and the locked compound (for example, concrete), and the cement screw 3 is pulled out. Resistance The increase in force makes the cement screw 3 of the present invention less likely to fall off or loosen.
