(94)與凸栓(22)的鎖固方式，必對業者有所幫助，遂有改進的 必要。 • 又，滑座（2)底部的容槽(21)需供擋塊(8)嵌入，而擋塊(8) 鲁 是以兩侧的小凸塊(81)與滑座執槽（12)兩侧的小凹口（13)對 正配合後才能達到固定，由於這種固定方式需使用到擋塊 ⑻，所以在製造、加工、組裝配合、及生產成本等方面，都 會帶給製造業者不少麻煩，故有改進的必要。 前案的紗線空氣喷嘴中’除了滑座⑵、扳塊⑷、播塊⑻ ，塑膠材質’紐⑶與以⑽為陶斜，其餘耕結構都 是金屬材質，在目前金屬價格上揚的時代裡，使用的金屬材料 • 愈多’生產成本就相對提高，因此如何減少使用金屬材料，便 • 成為本新型欲解決的問題點。 二、本新型的技術手段： • 基於上述關繼，本新型的目的在域供—種以塑膠材 ^製作、易於拆卸與組合、便於峨維護保養、鎖固力道平均、 能多次重複使用、及降低生產成本的紗線空氣喷嘴。 ^解決上·題點及_本_的目的，本新型的技術 手段是這樣實現的’其共有二個主要請求，第一個主要請求是 一種紗線空㈣嘴⑽），是由—具錢财⑻的基座 8 M322410 (10)、一藉由短軸栓(20)樞設在前述雙拱臂（丨丨）内的壓臂 (50)、一固定在壓臂（5〇)前底部且結合有瓷片（61)的壓塊 (60)、一縱向設置在前述基座（1〇)後端且頂抵著壓臂（5〇)後底 部的擴張彈簧（12)、一設置在前述基座（10)上且結合瓷塊(4〇) 的滑座(30)、一藉由長軸栓(21)樞設在雙拱臂（11)上且結合另 一長軸栓(22)來推動滑座(30)前後滑動的扳塊(7〇)所組成；其 特徵在於··前述雙拱臂（11)以一短軸栓(23)樞設壓桿(8〇)，該 壓桿(80)藉助抵止部(81)扣壓在壓臂（5〇)上使該壓臂（50)前 端不輕易上翹，並使壓桿(80)的按壓部(82)與基座（1〇)後端產 生一間距。 根據上述第一主要請求的紗線空氣喷嘴（1〇〇)，其特徵在 於：所述壓桿(80)是由橫向的抵止部（81)與縱向的按壓部（82) 連結呈倒L形，而短樞軸(23)是設置在抵止部（81)的中央朝前 位置；而壓臂（50)的後上部具有對應前述抵止部（81)的凹陷部 (51)。 根據上述依附在第一主要請求下所屬附屬請求的紗線空 • 氣喷嘴（1〇〇)，其特徵在於··所述壓桿(80)的抵止部（81)底面 由前而後分別是大弧凹面（85a)、大弧凸面（84a)、小凹面 (85b)、及小弧凸面（84b)所組成；所述壓臂（5〇)的凹陷部（51) 由前而後分別是圓弧面（53)、平枕面(52)、及凸緣體(54)組 成；前述大弧凹面（85a)是壓制在圓弧面（53)上，大弧凸面（84a) 是壓制在平枕面（52)上，小凹面(85b)或小弧凸面(84b)是壓制 在凸緣體(54)上。 根據上述第一主要請求的紗線空氣噴嘴(1〇〇)，其特徵在 M322410 於：所述擴張彈簧（12)下端是嵌入於基座（10)後上部所設的垂 向凹孔（15)内，而上端則嵌入壓臂（50)後底部所設的垂向凹孔 (55)内。 第二個主要請求為一種紗線空氣喷嘴（100),是由一具有 雙拱臂（11)的基座（10)、一藉由短軸栓(2〇)樞設在前述拱雙臂 (11)内的壓臂（50)、一固定在壓臂（50)前底部且結合有瓷片 (61)的壓塊(60)、一縱向設置在前述基座（1〇)後端且頂抵著壓 • 臂（5〇)後底部的擴張彈簧（12)、一設置在前述基座（1〇)上且結 > 合瓷塊(40)的滑座（30 )、一藉由長轴栓(21)樞設在雙拱臂（11) 上且結合另一長軸栓(22)來推動滑座(30)前後滑動的扳塊(70) 所組成；其特徵在於：所述滑座(3〇)前端設置一用於扣固瓷塊 (40)前部的彈性扣片（33),而後端則設置一用於扣固瓷塊(4〇) 後部的彈性卡鉤(32)。 根據上述第二主要請求的紗線空氣喷嘴（1〇〇)，其特徵在 於：所述滑座（30)上具有一突出的定位凸塊(34)，而瓷塊(4〇) ) 的兩端分別設置對應前述定位凸塊(34)且供其嵌入的定位孔 • (42)。 根據上述第二主要請求的紗線空氣喷嘴（1〇〇)，其特徵在 於·所述彈性扣片（33)是垂直固定在滑座(3〇)前端且上部具有 突緣(331)的金屬簧片。 根據上述第二主要請求的紗線空氣喷嘴（100)，其特徵在 於··所述彈性卡鉤(32)與滑座(3的是一體成型的塑製體，前述 彈性卡鉤(32)是懸立在滑座(3〇)後端的空槽(3〇2)上，其前部 具有一供瓷塊(40)後端易於導入的傾面（321)。 M322410 根據上述第二主要請求的紗線空氣喷嘴(1〇〇)，其特徵在 於··所述滑座（30)底面具有可容基座（1〇)導入於内的容槽 (301)，容槽的後端為開放性的開口，前端為封閉端。 三、對照先前技術之功效： 本新型第一主要請求的雙拱臂（U)後上部以一短軸栓(23) 樞設一壓桿(80) ’該壓桿(80)藉助抵止部（幻）底端的大弧凸面 (84a)與大弧凹面（85a)，隨時緊配扣壓在壓臂（5〇)後端的凹陷 部（51)上，以抵制擴張彈簧（12)頂擎壓臂（5〇)的力道；其次， 由於壓桿(80)的按壓部（82)具有較長的施力距，施以一較小外 力便能將壓臂（50)下壓，即具有以大輸入運動產生小輸出運動 的省力效果，並使前端抵止部(81)翹起，這時壓臂（5〇)前端亦 伴隨上揚，使結合有瓷片（61)的壓塊（6〇)不再壓制著瓷塊 (40) ’此·時加壓桿(81)的小弧凸面（84b)便會扣壓在壓臂（5〇) 的凸緣體（54)上，以避免壓臂（5〇)過於上揚而造成滑座（3〇) 自動脫落，基於此，本新型就無需使甩前案的手工具來開閉壓 臂（50)，所以能避免使用手工具的困擾。 本新型擴張彈簣（12)下端是由上而下喪入於基座（1〇)的 垂向凹孔（15)内，無需使用前案的調整螺絲來止擋擴張彈簀 (12)，所以省掉組裝調整螺麻煩；而上端是嵌入壓臂（5〇)的垂 向凹孔(56)内，使壓臂（50)的後端部始終緊頂著壓桿(go)前端 的抵止部（81)，因此，在壓臂（50)與壓桿(80)之間產生槓桿作 用時，就能發揮極佳的施力效果。 本新型第二主要請求的滑座（30)前端設置一用於扣固兗 塊(40)前部的彈性扣片（33)，而後端則設置一用於扣固莞塊 11 M322410 (40)後部的彈性卡鉤(32);此種固定方式，已搏除前案以螺絲 配合擋刪定銳所造成的不便，同時德聽如·滑座之 凸栓的内螺孔易崩牙問題發生；再者，能使竟塊⑽迅速地固 定在滑座(30)上，而且夾持穩固，且在取出瓷塊(4〇)時也非常 方便與快速。 本麵滑座⑽)上具有-突$的定位凸塊(34)可後入莞 塊(40)兩端的任一端定位孔(41)内而達到定位效果，使瓷塊 (40)在滑座(30)上不會產生偏位或異動。 > 本新型彈性扣片（33)是一金屬簧片，其以射包成型技術垂 直固定在滑座（30)的前端，而上部具有用於卡入瓷塊(4〇)前端 的突緣(331)，由於金屬簀片是沖製加工成型，所以彈性扣固 效果極佳。 本新型彈性卡鉤(32)與滑座(30)是一體成型的塑製體，該 彈性卡鉤（32)是懸立在滑座（3〇)後端的空槽（3〇2)上，所以具 有適當的彈性以對瓷塊(40)後端產生扣固作用，又彈性卡鉤 I— (32)前具有傾面（321)能使兗塊(40)後端易於朝下導入。 ， 本新型滑座（3〇)底面具有可容基座（1〇)導入於内的容槽 (37)，該容槽的後端為開放性的開口，所以能使基座（1〇)順利 地由容槽(37)後端導入於内，而前端為封閉端，所以能阻擋基 座（10)前進；由於本新型並未使用前案的擋塊結構，所以減少 了一項組合元件，但這能使本新型組合更簡化、維護更容易、 製造成本更降低。 【實施方式】 以下即依據圖面所示的實施例詳細說明如後： 12 M322410 、如圖1所示為本新型紗線空氣喷嘴的立體分解圖，圖2所 示為圖1紗線空氣喷嘴閉合時的示意圖，圖3所示為圖2之扳 塊去除後的立體透視圖，圖4所示為圖1紗線空氣喷 狀的立體圖，圖5所示為圖i之基座結合壓臂、壓桿、及^塊 的。’J面圖’圖6所示為圖1之基座結合滑座、变塊的剖面圖。 上圖中揭示出本新型紗線空氣喷嘴（1〇〇)，是由一具有雙 拱臂（11)的基座（10)、一藉由短軸栓(2〇)樞設在前述雙拱臂 (11)内的壓臂（50)、一固定在壓臂（50)前底部且結合有瓷片 (61)的壓塊⑽、-縱向設置在前絲座⑽後端且頂抵著廢 臂(50)後底部的擴張彈簧（12)、一設置在前述基座（1〇)上且結 合瓷塊(40)的滑座(30)、一藉由長軸栓(21)樞設在雙拱臂（11) 上且結合另一長軸栓(22)來推動滑座（3〇)前後滑動的扳塊(7〇) 所組成。 上述中，滑座(30)呈英文的L字形，其後上端具有開口槽 (31)以容-絲栓(21)橫置軸，而長軸栓(⑴的兩端更枢設 在扳塊(70)的兩側臂（73)後下部（如圖3所示）；當扳塊(7〇) 旋動時，可藉由長軸栓(21)來推動滑座（3〇)移動（如圖4所 示）；又，上述扳塊(70)的二侧臂（73)是藉由另一長軸栓(22) 與拱臂（11)福設結合，所以扳塊(70)能在麵臂⑴）上旋動。 上述壓臂(50)前部下緣具有一橫向卡溝⑽，而扳塊⑽ 的底面設置一對應前述卡溝（55)且能微微卡入固定的卡塊 (71)(如圖5所示）。 一 本新型的特徵如圖5所示，在於雙拱臂（11；)後上部以一短 軸栓⑽樞設-壓桿⑽，該壓桿⑽是由橫向的抵止部⑻） 13 M322410 與縱向的按壓部（82)連結呈倒L形，而短樞軸(23)是設置在抵 止部(81)的中央朝前位置；而壓臂（50)的後上部具有對應前述 抵止部（81)的凹陷部（51) 〇 上述壓桿(80)的抵止部（81)底面由前而後分別是大弧凹 面（85a)、大弧凸面（84a)、小凹面（85b)、及小弧凸面（84b); 所述凹陷部（51)由前而後分別是圓弧面（53)、平枕面（52)、及 凸緣體（54);前述大弧凹面（85a)是壓制在圓弧面（53)上，大 > 弧凸面（84a)是壓制在平枕面（52)上，小凹面（85b)或小弧凸面 (84b)是壓制在凸緣體(54)上，藉此使壓桿(80)的抵止部（81) 隨時緊配扣壓在壓臂（50)後端的凹陷部（51)上，以抵制擴張彈 簧（12)頂擎壓臂（50)的力道;其次，所述壓桿(8〇)的按壓部(82) 具有相互對應的圓弧面（86a、86b)，而其一圓弧面（86b)具有 供手指按屬且止滑的凹凸紋，使壓桿（80)被施以一外力按壓 後，其按壓部（82)會與基座（10)後端產生一施力移動的間距。 上述擴張彈簧（12)下端是由上朝下嵌入於基座（1〇)後上 > 部所設的垂向凹孔（15)内，無需使用前案（公告第454768號） - 的調整螺絲來止擋擴張彈簧（12)，所以省掉組裝調整螺麻煩； 而擴張彈簧（12)上端則嵌入壓臂（50)後底部所設的垂向凹孔 (56)内’使壓臂（50)的平枕面（52)、圓弧面(53)及凸緣體(54) 始終緊頂著壓桿(80)的大弧凸面（84a)、大弧凹面（85a)及小凹 面(85b) 〇 本新型的另一特徵如圖6所示，滑座（30)前端設置一用於 扣固瓷塊(40)前部的彈性扣片（33)，而後端則設置一用於扣固 竞塊(40)後部的彈性卡鉤(32)，前述彈性卡鉤(32)及彈性扣片 M322410 (33)皆卡扣在定位槽(41)内；此種固定方式，已摒除前案（公 告第454768號）以螺絲配合擋帽固定竟塊所造成的不便，同 時也能避免如前案滑座之凸栓的内螺孔易崩牙問題發生；再 者’能使究塊(40)迅速地固定在滑座（3〇)上，而且夹持穩固， 且在取出瓷塊(40)時也非常方便與快速。 上述滑座（30)上具有一突出的定位凸塊(34)，而瓷塊(4〇) 的兩端分別設置對應前述定位凸塊(34)且供其嵌入的定位孔 (42);當前述定位凸塊(34)嵌入瓷塊(4〇)任一端的定位孔(42) > 内，就能使瓷塊(40)在滑座（30)上不產生偏位或異動。 上述彈性扣片（33)是垂直固定在滑座（3〇)前端且上部具 有突緣(331)的金屬簧片，其以射包成型技術垂直固定在滑座 (30)的前端，而上部具有用於卡入瓷塊前端的突緣 (331) ’由於金屬簧片是沖製加工成型，所以彈性扣固效果極 佳。 上述彈性卡鉤(32)與滑座(30)是一體成型的塑製體，該彈 • 性卡鉤(32)是懸立在滑座（30)後端的空槽(3〇2)上，其前部具 • 有一供瓷塊(40)後端易於導入的傾面（321)。 上述滑座（30)底面具有可容基座（1〇)導入於内的容槽 (37)，該容槽(37)的後端為開放性的開口，所以能使基座〇〇) 順利地由容槽(37)後端導入於内，而前端為封閉端，所以能阻 播基座（10)前進，·由於本新型並未使用前案的擋塊結構，所以 減少了一項組合元件，但這能使本新型組合更簡化、維護更容 易、製造成本更降低。 其次，在滑座（30)的前端左右兩側具有垂直凸出的擋體 15 M322410 (39) ’以用於止擋瓷塊(40)的前端，使瓷塊(40)在滑座（3〇) 上的設置更為穩固；又，前述二擋體(39)之間的滑座（3〇)前端 還具有透空的框槽(37)，該框槽(37)的形成能助於彈性扣片 (33)的設置。另外，滑座（3〇)的兩侧具有防滑用的止滑紋 (35)，能在雙指夾取滑座(3〇)時達到防滑效果。 再者，為防止氣體產生洩漏，在滑座（3〇)的通氣孔(36) 的孔口上設置一止漏墊圈（38)，另在基座（1〇)的通氣孔（13) 孔口上也設置一止漏墊圈（14);當瓷塊(4〇)的通氣孔(43)與前 述通氣孔(36、13)垂直對稱配合後，在二止漏墊圈（38、μ) 的防範下，使空氣能由下往上垂直通過通氣孔(43、36、13) 然後對瓷塊(40)之半圓孔槽(44)中通過的紗線(未揭）進行吹 氣。 如圖.7〜圖9所示為本新型的剖面動作示意圖，圖7揭示 出壓臂（50)以前端壓塊(60)下的瓷片（61)壓制著滑座（3〇)上 的瓷塊(40)，而扳塊(70)以底下凸出的擋片（72)壓制著兗塊 - (4〇)的前部，且扳塊(70)底下的卡塊(71)扣入壓臂（50)前的卡 溝(55)内；這時壓桿(80)藉助抵止部（81)底端的大弧凸面（84a) 與大弧凹面（85a)，隨時緊配扣壓在壓臂（50)後端的凹陷部（51) 上，以抵制擴張彈簧（12)頂擎壓臂（50)的力道。 其次，如圖8揭示出扳塊(70)向上掀轉時，能以長軸栓(22) 為轴心’且藉助長轴检(21)推動滑座(30)前移，然而這時滑座 (30)仍因其上的瓷塊(40)被結合-有瓷片（61)的壓塊(6〇)壓制 在基座（10)内。 此外，如圖9所示，由於上述壓桿(80)的按壓部（82)具有 16 M322410 較長的施力距，施以一較小外力便能將壓臂（5〇)下壓，即具有 以大輪入運動產生小輸出運動的省力效果，並使前端抵止部 (81)翹起，這時壓臂（5〇)前端亦伴隨上揚，使結合有瓷片（Μ) 的壓塊(60)不再壓制著瓷塊(4〇)，而在同時，加壓桿(81)的小 弧凸面（84b)會扣壓在壓臂（50)的凸緣體(54)上，再加上壓桿 (80)的連結處所形成的凹槽(83)、及按壓部（82)的弧凹面(86a) 月&抵觸在基座（1〇)後端的平突部（16a)及凹凸部（16b)，以避免 壓臂（50)過於上揚而造成滑座（3〇)自動脫落，因此，此時就能 1 針對滑座(30)上的竟塊(4〇)進行賴，基於此，本新型就無需 使用刖案（公告第454768號）的手工具來開閉壓臂（5〇；)，所以 能避免使用手工具的困擾。 再者’本新型除了瓷片（61)及瓷塊(4〇)是陶瓷材料、長短 軸栓(20〜23)為金屬材質外，其它所有組件都是塑製成型，此 不但使重量減輕、更能易於大量生產製造、又材料成本大大降 低、使具經濟效益。 • 以上，是依據本新型圖式詳細說明如後，唯業者能在不超 .越本嶋旨的細進行各種削合實施 用與本新型有關結構的實施形態，只要在不超出本新型要旨範 _的各種等效變更實施例，皆應涵屬於本新型㈣内。 17 M322410 【圖式簡單說明】 圖1:本新型紗線空氣喷嘴的立體分解圖。 圖2 :為圖1紗線空氣喷嘴閉合時的立體圖。 圖3:為圖2之扳塊去除後的立體透視圖。 圖4:為圖1紗線空氣喷嘴呈開啟狀的立體圖。 圖5 :為圖1之基座結合壓臂、壓桿、及扳塊的剖面圖。 圖6:為圖1之基座結合滑座、瓷塊的剖面圖。 圖7〜圖9:為本新型的剖面動作示意圖。 • 【主要元件符號說明】 100 紗線空氣喷嘴 10 基座 11 雙拱臂 12 擴張彈簧 13 通氣孔 14 止漏墊圈 15 凹孔 16a 平枕面 16b 凹凸面 20、23 短轴栓 2卜22 長軸栓 30 滑座 301 容槽 — 302 空槽 31 開口槽 M322410 卡鉤 傾面 彈性扣片 突緣 定位凸塊 止滑紋 通氣孔 框槽 止漏塾圈 擋體 瓷塊 定位槽 定位孔 通氣孔 半圓孔槽 壓臂 凹陷部 平枕面 圓弧面 凸緣體 卡溝 凹孔 壓塊 瓷片 19 M322410 扳塊 卡塊 擋片 侧臂 加壓桿 抵止部 按壓部 凹槽 大弧凸面 小弧凸面 大弧凹面 小凹面 86a、86b 弧凹面M322410 VIII.
