Description

螺絲結構 Screw structure

本創作係與螺絲有關，尤指一種在結合兩個工件時可以將兩個工件拉緊而不致令工件間造成間距的螺絲構造。 This creation is related to screws, especially a screw structure that can tighten two workpieces without causing a gap between them when joining two workpieces.

螺絲具有固定物件或結合物件的功能，其取得容易且價格便宜，操作又非常方便，因此需求量很大。請參第5~6圖所示為目前螺絲在結合固定兩個物件，例如將兩個木板結合在一起時的連續操作示意圖，其包含一第一木板91、一第二木板92及一螺絲93，該螺絲93具有螺紋931，該螺絲93由其尖端932從第一木板91旋入並穿過第一木板91後，其尖端932接觸並刺入第二木板92時，此時螺紋931的前端935尚未旋入第二木板92中，在這種情形下會將第一木板91推開而形成一間隙P，這個間隙P會一直保持到螺絲93螺入時，因此讓第一木板91及第二木板92間形成有該間隙P，影響到第一木板91及第二木板92的結合。 Screws have the function of fixing objects or combining objects. They are easy to obtain and inexpensive, and they are very convenient to operate. Therefore, they are in great demand. Please refer to Figures 5 to 6 for the current schematic diagram of the continuous operation of screws when combining and fixing two objects, for example, when two wooden boards are combined together, which includes a first wooden board 91, a second wooden board 92 and a screw 93 The screw 93 has a thread 931. After the screw 93 is screwed in from the first wood board 91 by its tip 932 and penetrates the first wood board 91, when the tip 932 touches and pierces the second wood board 92, the front end of the thread 931 935 has not been screwed into the second wood board 92. In this case, the first wood board 91 will be pushed aside to form a gap P. This gap P will remain until the screw 93 is screwed in. Therefore, the first wood board 91 and the second wood board 91 The gap P formed between the two wooden boards 92 affects the combination of the first wooden board 91 and the second wooden board 92.

為了解決先前技術問題，本創作係在提供一種螺絲結構，可以克服先前技術中螺絲鎖入兩物件時，在兩物件間形成 間隙的問題。 In order to solve the problem of the prior art, the author provides a screw structure, which can overcome the formation of the screw between the two objects in the prior art. The issue of gaps.

而本創作的螺絲結構包含有一桿體及一螺紋部，該桿體前端具有一漸縮部，該漸縮部具有一尖端，該螺紋部包含有螺繞在桿體上的第一螺紋，以及螺繞在該漸縮部上的第二螺紋，該第一螺紋及該第二螺紋係連接在一起，該第一螺紋的每一螺牙間距相同，該第二螺紋的螺牙間距大於第一螺紋的螺牙間距，該第二螺紋的每一螺牙間距不同，且其間距由第一螺紋往尖端方向漸增。 The screw structure of the present creation includes a rod body and a threaded part, the front end of the rod body has a tapered part, the tapered part has a tip, the threaded part includes a first thread wound on the rod, and A second thread wound on the tapered portion, the first thread and the second thread are connected together, the pitch of each thread of the first thread is the same, and the pitch of the second thread is greater than that of the first thread The thread pitch of the second thread is different from each thread pitch, and the pitch gradually increases from the first thread toward the tip.

上述之螺絲結構，其中，該第二螺紋的每一螺牙間距順序為a+n1，a+2n1，....a+yn1；

；a為第一螺紋的螺牙間距，P1為欲拉緊的距離，y為第二螺紋的螺牙數，n1為第二螺紋的螺牙間距係數。 In the above screw structure, the sequence of the pitch of each thread of the second thread is a+n1, a+2n1,...a+yn1;

; A is the thread pitch of the first thread, P1 is the distance to be tightened, y is the number of threads of the second thread, and n1 is the thread pitch coefficient of the second thread.

上述之螺絲結構，其中，該第二螺紋的螺牙數y為自定。 In the above screw structure, the number y of the second thread is self-determined.

上述之螺絲結構，其中，該第二螺紋的欲拉緊的距離P1為自定。 In the above screw structure, the distance P1 to be tightened of the second thread is self-determined.

上述之螺絲結構，其中，該桿體後端具有一頭部，該頭部設有一施力槽。 In the above-mentioned screw structure, the rear end of the rod body has a head, and the head is provided with a force applying groove.

本創作藉由螺絲中的第二螺紋的間距大於第一螺紋的間距，且第二螺紋的每一螺牙間距往前漸增，而螺絲轉一圈時第二螺紋位置的直線方向移動的行程大於第一螺紋位置的直線方向移動的行程，因此，結合兩工件時，螺絲第二螺紋穿入第一工 件，再從第一工件進入到第二工件時，造成第一工件及第二工件的間隙，可以藉由螺絲的第二螺紋進入第二工件後，因與第一螺紋間的行程差，將第一工件往第二工件拉近，可以解決兩個工件間的間隙問題。 In this creation, the distance between the second thread in the screw is greater than the distance between the first thread, and the distance between each thread of the second thread gradually increases forward, and the stroke of the second thread position when the screw rotates in a linear direction. It is greater than the linear movement stroke of the first thread position. Therefore, when the two workpieces are combined, the second thread of the screw penetrates into the first workpiece. When the workpiece enters the second workpiece from the first workpiece, the gap between the first workpiece and the second workpiece is caused. After the second thread of the screw enters the second workpiece, the stroke difference with the first thread will reduce The first workpiece is drawn closer to the second workpiece, which can solve the gap problem between the two workpieces.

以上兩個實施例僅供說明，讓閱讀者能理解但並不在限制本專利之範圍。 The above two embodiments are for illustration only, so that readers can understand, but they do not limit the scope of this patent.

上述即為本創作一較佳實施例所提供之一種螺絲結構100之各部構件及其組成方式介紹，接著再將其使用特點說 明如下： The above is an introduction to the various components of a screw structure 100 provided by a preferred embodiment and their composition methods, and then the characteristics of its use are described. The instructions are as follows:

請參第2~4圖所示，為本創作螺絲結構100鎖入第一工件31及第二工件32的使用操作連續示意圖。其中第2圖顯示本創作的螺絲結構100先由第二螺紋22穿過第一工件31，再從第一工件31的位置進入第二工件32，這時將第一工件31往後推(參第2圖箭頭)，因此，在第一工件31及第二工件32間產生間隙P1，而這個間隙P1就是前面所述兩個工件間欲拉緊的距離P1。當螺絲結構100再往第二工件32旋入時，螺絲結構100的第二螺紋22進入第二工件32後，因為第二螺紋22直線方向移動行程大於第一螺紋21直線方向移動行程，而將第一工件31往第二工件32拉近(參第3圖箭頭所示)，一直到螺絲結構100完全鎖入第一工件31及第二工件32，而將兩個工件結合(參第4圖所示)，而且兩個工件間會越來越緊，解決了先前技術中兩工件間產生間隙的問題。 Please refer to Figures 2 to 4, which are a continuous schematic diagram of the use operation of locking the first work piece 31 and the second work piece 32 of the creative screw structure 100. The second figure shows that the screw structure 100 of the present creation first passes through the first workpiece 31 by the second thread 22, and then enters the second workpiece 32 from the position of the first workpiece 31, and then pushes the first workpiece 31 back (see section Fig. 2 arrow), therefore, a gap P1 is generated between the first work piece 31 and the second work piece 32, and this gap P1 is the distance P1 to be tightened between the two work pieces mentioned above. When the screw structure 100 is screwed into the second workpiece 32 again, after the second thread 22 of the screw structure 100 enters the second workpiece 32, because the linear movement stroke of the second thread 22 is greater than the linear movement stroke of the first thread 21, the The first workpiece 31 is drawn closer to the second workpiece 32 (refer to the arrow shown in Figure 3), until the screw structure 100 is completely locked into the first workpiece 31 and the second workpiece 32, and the two workpieces are combined (refer to Figure 4) As shown), and the two workpieces will become tighter and tighter, which solves the problem of gaps between the two workpieces in the prior art.
