Description

軟管可旋轉接頭
本發明係有關於一種水管連接接頭，尤指一種用於連接供水或用水端且具有兩端相對旋轉功能之軟管可旋轉接頭。
按，習知應用於噴水槍之連接接頭，如第12、13圖所示，其主要包括有一連接頭50與一軟管60，該連接頭50一端形成有一螺紋段51，且該螺紋段51用於鎖設牆面水管接頭、水龍頭或噴水槍，又該連接頭50另一端形成有一束緊段52，且該束緊段52用於連接該軟管60，當使用者要將該軟管60連接至水管接頭或水龍頭時，該連接頭50之螺轉將會帶動該軟管60同步旋轉，使該軟管60形成扭轉或捲繞之情況，造成組裝時之困擾，又於使用者將連接頭50連接噴水槍時，因為需要採用不同方向或角度操作噴水，是故該噴水槍將會對軟管60產生有旋轉或扭轉之外力，其外力將會導致該軟管60形成扭轉或捲繞之情況，故常會發生該軟管60的打結纏繞，不僅會造成噴水操作之阻礙與增加水管收捲之難度，亦會因為打結纏繞所造成之阻力而提高水管內部水壓，使該水管容易爆裂或水管自行由該供水設備端脫離之可能，更進一步還會造成該連接頭50之鬆脫與損壞，此為本創作所欲解決之技術問題點。
有鑑於此，本發明人於多年從事相關產品之製造開發與設計經驗，針對上述之目標，詳加設計與審慎評估後，終得一確具實用性之本發明。
本發明所欲解決之技術問題在於針對現有技術存在的上述缺失，提供一種軟管可旋轉接頭。
一連接外管貫穿有一通孔，且該通孔的內緣凸設有一內環圈，又該連接外管一端形成有一扳動部，且該連接外管另一端形成有一螺鎖部，一連接內管貫穿有一穿孔，且該穿孔於一端開口處形成有一具多邊形之鎖設內孔，又該連接內管外表面的一端凸設有一擴大環部，且該連接內管由該擴大環部向另一端依序形成有一第一凹圈、一第二凹圈及一外螺紋段，又該第一凹圈內裝設有一第一止水環，且該第二凹圈內裝設有一第二止水環，又該連接內管置入於該連接外管之通孔，讓該擴大環部抵觸於該內環圈，讓該第一止水環夾設於該連接外管與該連接內管之間，而該第二止水環與該外螺紋段穿出該連接外管，一軟管接頭一端形成有一螺帽，且該螺帽開設有一內螺紋段，而該軟管接頭於該內螺紋段的外側形成有一無螺紋段，又該軟管接頭以該內螺紋段鎖設於該連接內管之外螺紋段，且該無螺紋段與該第二凹圈互相抵觸該第二止水環，另該軟管接頭另一端形成有一束緊段，一軟管一端套設於該束緊段，且該束緊段與該軟管的連接處擠壓固定有一金屬套。
其中，該螺鎖部形成於該連接外管之外表面呈螺紋狀，藉此以內鎖方式連接一噴水槍或一灑水器。
其中，該螺鎖部形成於該連接外管之內表面呈螺紋狀，藉此以外鎖方式連接一水龍頭。
其中，該軟管接頭之無螺紋段的外緣形成有一導斜面，且該 導斜面讓該無螺紋段容易滑過該第二止水環。
其中，該連接內管之鎖設內孔呈內六角、星形、梅花形之形狀。
其中，該軟管接頭之束緊段外表面形成有複數個逆向斜錐面，且該逆向斜錐面配合該金屬套擠壓該軟管。
本發明的第一主要目的在於，當噴水動作導致噴水槍與軟管之間有互相旋轉或扭轉時，由於該連接內管之擴大環部與該軟管接頭之螺帽係相對阻擋於該內環圈的兩端，因此該連接內管、該軟管接頭與該軟管將不會隨著該連接外管一起旋轉，藉此防止噴水槍與該軟管之間產生有扭轉或捲繞之情況發生，俾以提高用水操作之便利性。
本發明的第二主要目的在於，於該連接外管以該螺鎖部進行鎖設動作時，該連接內管之擴大環部與該軟管接頭之螺帽係相對阻擋於該內環圈的兩端，因此該連接內管、該軟管接頭與該軟管將不會隨著該連接外管一起旋轉，藉此有效防止該軟管於鎖設連接時產生扭轉或捲繞情況，俾以提高管路連接之便利性。
本發明的第三主要目的在於，該連接外管與該連接內管之間以該第一止水環形成防漏效果，且該連接內管與該軟管接頭之間以該第二止水環形成防漏效果，並讓該連接外管與該連接內管之間僅形成該內環圈的少量面積接觸，即能在有效防漏之前提下，進一步提高該連接外管與該連接內管之間的可滑動性，使其操作時更為省力，亦不容易黏死導致失去相對旋轉之功能，俾以提高其實用性。

為使 貴審查委員對本發明之目的、特徵及功效能夠有更進一步之瞭解與認識，以下茲請配合【圖式簡單說明】詳述如後：
先請由第1圖、第2圖與第3圖所示觀之，一種軟管可旋轉接頭，其包括有：一連接外管10、一連接內管20、一軟管接頭30及一軟管40，一連接外管10貫穿有一通孔11，該通孔11的內緣凸設有一內環圈12， 又該連接外管10一端形成有一扳動部13，且該連接外管10另一端形成有一螺鎖部14，一連接內管20貫穿有一穿孔21，且該穿孔21於一端開口處形成有一具多邊形之鎖設內孔22，而該連接內管20之鎖設內孔22呈內六角、星形、梅花形之形狀(配合第9、10、11圖所示)，又該連接內管20外表面的一端凸設有一擴大環部23，且該連接內管20由該擴大環部23向另一端依序形成有一第一凹圈24、一第二凹圈25及一外螺紋段26，又該第一凹圈24內裝設有一第一止水環27，且該第二凹圈25內裝設有一第二止水環28，又該連接內管20置入於該連接外管10之通孔11，讓該擴大環部23抵觸於該內環圈12，讓該第一止水環27夾設於該連接外管10與該連接內管20之間，而該第二止水環28與該外螺紋段26穿出該連接外管10，一軟管接頭30一端形成有一螺帽31，該螺帽31開設有一內螺紋段32，而該軟管接頭30於該內螺紋段32的外側形成有一無螺紋段33，又該軟管接頭30以該內螺紋段32鎖設於該連接內管20之外螺紋段26，且該無螺紋段33的外緣形成有一導斜面331，且該導斜面331讓該無螺紋段33容易滑過該第二止水環28，藉此提高鎖設時該第二止水環28之結構穩定性，讓該無螺紋段33與該第二凹圈25互相抵觸該第二止水環28，另該軟管接頭30另一端形成有一束緊段34，一軟管40一端套設於該束緊段34，該束緊段34與該軟管40的連接處擠壓固定有一金屬套41，其中，該軟管接頭30之束緊段34外表面形成有複數個逆向斜錐面341，且該逆向斜錐面341配合該金屬套41擠壓該軟管40，藉此該軟管40、該軟管接頭30與該連接內管20能同步相對該連接外管10進行自由旋轉。
其結構之組合，再請由第2、3、4圖所示觀之，該連接內管 20於該第一凹圈24與該第二凹圈25分別裝設有該第一止水環27與該第二止水環28，再將該連接內管20置入該連接外管10之通孔11內，讓該連接內管20之外螺紋段26穿過該內環圈12，使該外螺紋段26與該第二止水環28皆伸出該連接外管10形成外露狀，而該擴大環部23抵靠於該內環圈12一側，同時該第一止水環27夾設於該內環圈12與該連接內管20之間，藉此具有防漏之功效，又該軟管接頭30之束緊段34套設有該軟管40，更進一步套設該金屬套41，透過擠壓該金屬套41束緊該軟管40，使該軟管40無法脫離該束緊段34之逆向斜錐面341，再將該軟管接頭30之螺帽31鎖設於該連接內管20之外螺紋段26，於鎖設時利用手工具固定該連接內管20之鎖設內孔22，即能形成該連接內管20端之防轉，就能順利轉動該螺帽31形成螺轉鎖入，又該軟管接頭30之導斜面331能讓該無螺紋段33容易滑過該第二止水環28，並於螺鎖時以該無螺紋段33接觸該第二止水環28，藉此防止螺帽31夾住該第二止水環28，或該內螺紋段32接觸該第二止水環28，防止於鎖入時造成該第二止水環28產生扭轉變形或拉扯破損之情況，俾以提高組裝良率，即讓該第二止水環28夾設於該連接內管20與該無螺紋段33之間形成防漏效果，其實際使用之情況，該連接外管10以該螺鎖部14鎖設於水管、噴水槍或水龍頭等供水或用水元件，如第5、6圖所示，該螺鎖部14形成於該連接外管10之外表面呈螺紋狀，藉此以內鎖方式連接一噴水槍A或一灑水器C，當噴水動作導致噴水槍A(或灑水器C)與軟管40之間有互相旋轉或扭轉時，由於該連接內管20之擴大環部23與該軟管接頭30之螺帽31係相對阻擋於該內環圈12的兩端，因此該連接內管20、該軟管接頭30與該軟管40將不會隨著該連接外管10一起旋轉，藉此防止噴水 槍A(或灑水器C)與該軟管40之間產生有扭轉或捲繞之情況發生，俾以提高用水操作之便利性，又如第7、8圖所示，該螺鎖部14形成於該連接外管10之內表面呈螺紋狀，藉此以外鎖方式連接一水龍頭B或水管接頭，於該連接外管10以手工具帶動該扳動部13，讓該螺鎖部14進行鎖設動作時，該連接內管20之擴大環部23與該軟管接頭30之螺帽31係相對阻擋於該內環圈12的兩端，因此該連接內管20、該軟管接頭30與該軟管40將不會隨著該連接外管10一起旋轉，藉此有效防止該軟管40於鎖設連接時產生扭轉或捲繞情況，俾以提高管路連接之便利性，另一方面，該連接外管10與該連接內管20之間以該第一止水環27形成防漏效果，且該連接內管20與該軟管接頭30之間以該第二止水環28形成防漏效果，並讓該連接外管10與該連接內管20之間僅形成該內環圈12的少量面積接觸，即能在有效防漏之前提下，進一步提高該連接外管10與該連接內管20之間的可滑動性，使其操作時更為省力，亦不容易黏死導致失去相對旋轉之功能，俾以提高其實用性。
綜上所述，本發明確實已達突破性之結構設計，而具有改良之發明內容，同時又能夠達到產業上之利用性與進步性，且本發明未見於任何刊物，亦具新穎性，當符合專利法相關法條之規定，爰依法提出發明專利申請，懇請 鈞局審查委員授予合法專利權，至為感禱。
唯以上所述者，僅為本發明之一較佳實施例而已，當不能以之限定本發明實施之範圍；即大凡依本發明申請專利範圍所作之均等變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。
