• 多種管件鉗具，如美國專利US 2,559,973及US 6’026, 714等專利前案，這些管鉗主要包含有一手柄 ，手柄頂端具設有一具多數咬合齒的固定顎塊，且手 柄頂端另樞設有一可相對固定顎塊夾合或分離之活動 夾顎，該活動夾顎並利用彈性元件使其常保有相對固 定顎塊夾合的預力，且該活動夾顎内面亦形成有與固 疋顎塊咬合齒相對的多數咬合齒，在前述的專利中， 固定顎塊的複數咬合齒係呈弧形延伸，而活動夾顎内 面的咬合齒則形成兩具夾角的延伸面，供利用活動夾 顎與固定顎塊之咬合齒形成三點接觸來夾緊圓形的被 夾持物； 别述管鉗進一步並利用活動夾顎的樞設，來配合 被夾持物的不同直徑來張閤，但當活動夾顎的擺幅超 過一定角度後’其即使會活動夾顎與固定顎塊之咬合 齒無法有效的咬合在被夹持物的周面，造成咬合點摩 擦力降低的現象，進而產生打滑的現象，影響到管鉗 夾掣被夾持物的效果，造成使用者操作上的不便與困 擾。 5 1332883 而為了能進一步提升這類管鉗的摩擦力與夾掣力 ，業界進一步提出多件專利，以求透過不同的技術來• A variety of pipe fittings, such as U.S. Patent No. 2,559,973 and U.S. Patent No. 6, 026, 714, each of which incorporates a handle having a fixed gusset at the apex of the handle and a distal end of the handle. The utility model is provided with a movable clamp which can be clamped or separated with respect to the fixed clamping block, and the movable clamping member uses the elastic member to maintain the pre-stress of the relatively fixed clamping block, and the inner surface of the movable clamping jaw is also formed and fixed. In the above patent, the plurality of occlusal teeth of the fixed mortise block extend in an arc shape, and the occlusal teeth on the inner surface of the movable jaw form two extended angles for the use of the movable clip. The cymbal forms a three-point contact with the occlusal teeth of the fixed cymbal to clamp the circular object to be clamped; the pipe tongs are further used and the pivoting of the movable clamp is used to fit the different diameters of the clamped object, but when After the swing of the movable clamp exceeds a certain angle, even if the engaging teeth of the movable clamp and the fixed clamp cannot be effectively engaged on the circumferential surface of the clamped object, the frictional force of the occlusal point is lowered. Slip phenomenon is generated, the impact effect of the latch tube clamp jaw clamped object, causing inconvenience to the user operation to plague. 5 1332883 In order to further enhance the friction and clamping force of these pipe wrenches, the industry has further proposed several patents in order to use different technologies.
解決前述的問題，如美國專利US 6,742,419、US 7,044’03(3 及 US 7, 096, 764 等。而以其中 us 6, 74^419與（JS 7, 044, 030為例，其活動夾顎的第一 、二齒面可沿一軸線相對固定顎塊環繞分離或靠近， 前j活動夾顎之第一、二齒面與固定顎塊的咬合齒具 有一頂尖，各咬合齒的頂尖與該活動夾顎軸線有關地 角度R與在前的咬合齒的頂尖錯開，該角度R由公式 R_TR* (D卜D2) / (D3-D2)決定’使其可有效的提 升夾掣多種不同直徑的被夾持物之摩擦力，避免發生 打滑的現象。至於us 7,096,764則係令其中的^動 夾顎内側排列齒牙呈V型為115度，其亦在於增進其 夾掣被夾持物的咬合摩擦力，防止管鉗於操作過程/中 打滑。 換言之，如能提升管鉗咬合被夾持物的摩擦力， 即可增強其夾掣力，使管鉗咬合被夾持物轉動^，不 致因管件變形而發生滑動的現象，相信可提高管鉗 經濟價值。 有鑑於此’本發明人乃針對使用者希望能進一步 提升管鉗咬合摩擦力的需求深入探討，並藉由多年^ 事相關產業的開發經驗’積極尋求解決之道，經不斷 努力之研究與試作，終於成功的創作出—種管二結構 ’藉以有效增進管鉗的夾掣力’防止管鉗於操作^程 中發生打滑的現象。 6 1332883 【圖式簡單說明】 第一圖：係本發明管鉗結構之外觀示意圖，用以說明管鉗之 構成及其相對關係。 第二圖：係本發明管鉗結構之局部放大示意圖。 第三圖：係本發明管鉗結構之平面標示示意圖。 麵 【主要元件符號說明】 (10) 手柄 (12) 樞軸 (13) 扭力彈簀 (15) 弧型顎塊 (150) 咬合齒 (20) 活動夾顎 (21) 第一齒面 (210) 咬合齒 (22) 第二齒面 (220 ) 咬合# 11To solve the aforementioned problems, such as U.S. Patent No. 6,742,419, US 7,044'03 (3 and US 7, 096, 764, etc., and in the case of us 6, 74^419 and (JS 7, 044, 030, for example, its movable folder) The first and second tooth surfaces may be separated or adjacent to each other along an axis, and the first teeth of the front j movable jaw and the fixed teeth have a tip, and the tip of each bite is The angle R between the axis of the movable jaw axis is offset from the tip of the preceding bite. The angle R is determined by the formula R_TR* (D Bu D2) / (D3-D2), which makes it possible to effectively lift the clips of various diameters. The friction of the clamped object avoids the occurrence of slipping. As for us 7,096,764, the inner tooth of the movable clamp is arranged at a V-shape of 115 degrees, which is also to improve the occlusal friction of the clamped object. In order to prevent the pipe wrench from slipping during operation/slippery. In other words, if the pipe wrench can be lifted to engage the friction of the clamped object, the clamping force can be enhanced, and the pipe wrench can be engaged by the clamped object, so that the pipe clamp does not deform. The phenomenon of sliding is believed to increase the economic value of pipe wrenches. This inventor has in-depth discussion on the user's desire to further improve the frictional force of the pipe wrench, and has been actively seeking solutions through years of experience in the development of related industries, and has been continuously researching and trialing. The successful creation of the tube-two structure 'to effectively improve the clamping force of the pipe wrench' prevents the pipe wrench from slipping during the operation. 6 1332883 [Simple diagram of the drawing] The first figure: the pipe wrench of the invention The appearance of the structure is used to illustrate the structure of the pipe wrench and its relative relationship.
