I 元（A)以形成一鏈條構造，而在於該鏈條彐端之串接單元 〇 (A)之間則需要以二相對之外鏈片(B)配合鏈軸（A 3)穿設 固定予以結合，其中該鏈軸（A3) —端設有固定部（A31) ，而另一端則設有一扣合部（A 3 2 )，而該扣合部（A 3 2)則 接續連接有一直徑較小之頸部（A33)，又該二外鏈片（B) 上設有穿孔（B1)，以及一與穿孔（B1)左右間隔的扣合孔 (B2)，其中該穿孔（B1)係供鏈軸（A3)之固定部（A31)固 定於其中，又該扣合孔（B2)係設有一可供扣合部（A32) 穿伸之大徑部（B21)以及一與大徑部（B21)鄰接相切並且 寬度小於扣合部（A32)之小徑部（B22)，且該小徑部 098117684 (B22)之寬度大於鏈軸（A3)之頸部（A33)，又該小徑部 表單編號A0101 第3頁/共37頁 （ 201042182 (B22)之周'緣環繞凹設有-滑移面（B23)，又該二外鏈片 (B)係设呈為8字形，於二外鏈片（B)之二側腰部形成有 凹入部（B3)。 [0003] 組裝時，請參考第十六圖及第十七圖所示，將二鏈轴 (A3)之固定部（A31)先分別固定於二相對之外鏈片（B)上 ’並於二鍵轴（A3)上分別套合有串接單元（八），再將該二 外鍵片（B)以相對方向進行組裝，使二鏈軸（A3)之扣合部 (A32)分別先伸入二相對外鏈片（B)之扣合孔（B2)的大徑 部（B21)内’此時二相鄰内鏈片（A1)之間的間距係為 2. 36mm〔如第十六圖所示〕，再使其扣合部（A32)可分 別凸伸出外鏈片（B)以外，並將鏈轴（A3)之扣合部（A”） 沿著滑移面（B23)向小徑部（B22)移動後再向下按壓卡掣 ’使鏈轴（A3)之頸部（A33)可以伸入小徑部（B22)内被卡 掣，如此一來，二外鏈片（B)則可互相結合固定，此時組 裝完成後串接單元（A)上之内鏈片（A1)與鄰近的外鏈片 (B)之間必定會產生一較大的間隙（D )〔如第十八圖所示 〕，所以鏈軸（A3)與外鏈片（B)間容易產生相對移動，當 鏈軸（A3)之扣合部（A32)移動凸出於外鏈片（B)之外侧位 置時’一旦鏈軸（A3)此時又受到變速時產生朝向穿孔 (B1)方向之斜向拉力時，則其鏈轴（A3)即會朝向穿孔 (B1)的方向移動而脫落，故使用此種鏈條構造將有安全 上的疑慮；又存在於内鍵片（A1)與外鏈片（B)間的間隙 (D)，則會造成鏈條之各個串接單元（A)容易左右移位， 又由於串接單元（A)上的内鏈片（A1)與外鏈片（B)間的間 隙（D)較大，因此，在各個外鏈片（B)之凹入部（B3)與自 098117684 表單編號A0101 第4頁/共37頁 0982030067-0 201042182 '， 行車輪轴上飛輪（G)之齒塊（G1)相嚙合進行傳動或變速時 ❹ 〔如第十九圖所示〕，飛輪（G)上之齒塊（G1)尖端則會卡 入於該間隙（D)内而造成脫離及斷鏈狀況發生，也會造成 串接單元（A)左右移位，又由於鏈軸（A3)之扣合部（A32) 係凸出於外鏈片（B)之外侧位置，故在傳動或變速的過程 中會產生較大的碰撞、磨損及碰撞噪音，因此外鏈片（B) 之扣合孔（B2)之孔徑如向穿孔（B1)方向移動則厚度將變 薄，相對造成強度不足，如增加扣合孔（B2)至外鏈片（B) 周緣之寬度時，則會碰到飛輪（G)之齒塊（G1)底緣内外侧 (Η )，而有浮起情形，會有節距不準，產生雜音和不順暢 ，另齒塊（G1)底緣之壁厚也會變薄，而外鍵片（Β)之凹入 部（Β3)弧度不夠大時也容易碰到齒塊（G1)之底緣，因此 在使用上存在著有相當大的危險性。 嚤 [0004] 【發明内容】 爰此，有鑑於目前的鏈條接合構造之外鏈片與内鏈片之 間會因產生間隙而脫離，故本發明係在提無一種單腳快 〇 卡式鏈片，其係設有一第一外鏈片，其係設有一第一穿 孔及一相鄰之第一卡入孔，該第一卡入孔向二側反向延 伸連通有第一伸縮槽及第一扣合槽，其中該第一伸縮槽 位置係接近第一穿孔，而第一扣合槽位置則遠離第一穿 孔，並於該第一卡入孔之周緣壁面上沿著第一扣合槽凹 設有第一滑移面，且於第一卡入孔與第二扣合槽連通之 壁面位置處相向成型有至少一個以上之第一卡掣塊，另 於該第一外鏈片之第一穿孔内固定有一第一鏈軸，該第 一鏈軸一端設有第一扣合部，而該第一扣合部則接續連 098117684 接有一直徑小於第一扣合部之第一頸部；一第二外鏈片 表單編號Α0101 第5頁/共37頁 0982030067-0 201042182 ，其係設呈為與第-外鏈片相同形狀，並與該第—外鍵 片對應卡合’該第二外鏈片係設有_第二穿孔及—相鄰 之第二卡人孔’該第二卡人孔向二側反向延伸連通有第 二伸縮槽及第二扣合槽’其中該第二伸縮槽位置係接近 第二穿孔’而第二扣合槽位置則遠離第二穿孔，並於胃 第二卡入孔之周緣壁面上沿著第二扣合槽凹設有第二滑 移面’且於第二卡人孔與第二扣合槽連通之壁面位置: 相向成型有至少-個以上之第二卡掣塊，另於該第二外 鏈片之第二穿孔内^有—第二鏈軸，該第二__端 設有第二扣合部’而觀二扣合部祕續連射—直徑 Ο 小於第二扣合部之第二頸部β [0005] 上述該第-卡f塊係由第—滑移面向下延伸至第一外鍵 片之底部，㈣第二卡掣塊難由第二滑移面向下延伸 . 至第二外鏈片之底部。 ， [0006] 上述該第-卡掣塊係由第―扣秦槽壁緣之中段位置處向 下延伸至第—外鏈片之底部，而該魏卡f塊係由第二 扣合槽壁緣之中段位置處向下延伸至第二外鏈以㈣ y 〇 [0007] •小叹王兩弟一弧形面，另該 第二外鏈片之-外側係設呈為第二弧形面。 [0008] 上述該第-外鏈片於第-卡掣塊與第—扣合槽之間沿 著第一滑移面其中—單側之壁面位置處，僅成型有一第 一輔助卡掣塊，另該第二外 罐月於第二卡掣塊與第二扣 合槽之間，沿著第二滑移面其中„ 共中―早側之壁面位置處， 098117684 表單編號A0101 第6頁/共37 頁 0982030067-0 201042182 '' 僅成型有一第二輔助卡掣塊。 [0009] 上述該第一外鏈片於第一卡掣塊與第一扣合槽之間，沿 著第一滑移面二侧之壁面位置處，相向成型有二第一輔 助卡掣塊，另該第二外鏈片於第二卡掣塊與第二扣合槽 之間，沿著第二滑移面二侧之壁面位置處，相向成型有 二第二輔助卡掣塊。 [0010] 本發明亦可為一種單腳快卡式鏈片，係配合有一鏈條實 施，該鏈條之二端設有内鏈片，包括有：一第一外鏈片 0 ，其係設有一第一穿孔及一相鄰之第一卡入孔，該第一 卡入孔向二側反向延伸連通有第一伸縮槽及第一扣合槽 ，其中該第一伸縮槽位置係接近第一穿孔，而第一扣合 -

The chain shaft does not escape from the second snap-in hole and the first snap-in hole to ensure the safety of the chain in use. 0002 [0002] < [Prior Art] The current chain structure is mainly the prior art described in the specification of the "Chain Chain" patent of No. 1276751 of the Republic of China on March 21, 1996. That is, a conventional chain joint structure has been disclosed. Please refer to the fifteenth, sixteenth and seventeenth diagrams, which are mainly provided between the two inner links (A1). The chain roller (A2) and the two-chain shaft (A3) are combined into one tandem unit (A), and then combined with a plurality of tandem joints: .. I (A) to form a chain structure, and at the end of the chain The tandem unit 〇(A) needs to be coupled by two opposite outer links (B) with the chain shaft (A3), wherein the chain shaft (A3) is provided with a fixing portion (A31). ), while the other end is provided with a fastening portion (A 3 2 ), and the fastening portion (A 3 2) is connected to a neck having a smaller diameter (A33), and the two outer links (B) A perforation (B1) is provided, and a fastening hole (B2) spaced apart from the perforation (B1), wherein the perforation (B1) is fixed to the fixing portion (A31) of the chain shaft (A3) Wherein, the fastening hole (B2) is provided with a large diameter portion (B21) through which the fastening portion (A32) can be extended, and a tangential portion adjacent to the large diameter portion (B21) and having a width smaller than the fastening portion (A32) The small diameter portion (B22), and the width of the small diameter portion 098117684 (B22) is larger than the neck portion (A33) of the chain shaft (A3), and the small diameter portion form number A0101 is 3/37 (201042182 ( The circumference of B22) is surrounded by a concave-slip surface (B23), and the two outer chain pieces (B) are formed in a figure-eight shape, and a concave portion is formed on the waist of the two outer chain pieces (B). (B3) [0003] When assembling, please refer to the sixteenth and seventeenth figures, and fix the fixed part (A31) of the two-chain shaft (A3) to the two opposite outer links (B). The upper part is respectively fitted with a serial connection unit (8) on the two-key shaft (A3), and then the two outer key pieces (B) are assembled in opposite directions to make the fastening portion of the two-chain shaft (A3) ( 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 [as shown in Figure 16], and then make the buckle part (A32) separable When the outer link piece (B) is protruded, the engaging portion (A" of the chain shaft (A3) is moved along the sliding surface (B23) toward the small diameter portion (B22), and then the clicker is pressed downward. The neck (A33) of the chain shaft (A3) can be inserted into the small diameter portion (B22) to be jammed, so that the two outer chain pieces (B) can be combined and fixed to each other, and the assembled unit is assembled after completion of the assembly. A large gap (D) must be generated between the inner chain piece (A1) on the upper (A) and the adjacent outer chain piece (B) (as shown in Fig. 18), so the chain axis (A3) and When the outer chain piece (B) is easily moved relative to each other, when the engaging portion (A32) of the chain shaft (A3) moves to protrude from the outer side of the outer chain piece (B), once the chain axis (A3) is again subjected to When an oblique pulling force is generated in the direction of the perforation (B1) during shifting, the chain axis (A3) moves toward the perforation (B1) and falls off, so there is a safety concern when using such a chain structure; The gap (D) between the inner key piece (A1) and the outer link piece (B) causes the respective tandem units (A) of the chain to be easily displaced left and right, and the inner chain on the tandem unit (A) Sheet (A1) and outer chain piece The gap (D) between B) is large, so the recessed portion (B3) of each outer link piece (B) and the 909117684 form number A0101 page 4/37 pages 0992030067-0 201042182 ', on the wheel axle When the tooth block (G1) of the flywheel (G) is engaged for transmission or shifting ❹ [as shown in Fig. 19], the tip of the tooth block (G1) on the flywheel (G) is caught in the gap (D). Internal disconnection and chain scission occur, which also causes the tandem unit (A) to shift to the left and right, and the snap portion (A32) of the chain shaft (A3) protrudes from the outer side of the outer link (B). Therefore, in the process of transmission or shifting, large collision, wear and collision noise are generated, so that the aperture of the fastening hole (B2) of the outer link piece (B) is thinned as it moves toward the perforation (B1). Relatively insufficient strength, such as increasing the width of the peripheral hole (B2) to the outer edge of the outer chain piece (B), it will hit the inner side (Η) of the bottom edge of the tooth block (G1) of the flywheel (G), and In the case of floating, there will be inaccurate pitch, noise and smoothness, and the wall thickness of the bottom edge of the other tooth block (G1) will also become thinner, and the concave portion (Β3) arc of the outer key piece (Β) When large enough to easily hit the bottom edge of the toothed block (G1), the so there is considerable risk in use. 0004 0004 0004 0004 0004 0004 0004 0004 0004 0004 0004 [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ The first outer chain piece is provided with a first through hole and an adjacent first locking hole.
