Description
本發明係關於扳手,特別是指扳手被操作下具有能伸長與所縮短改變整體長度的扳手者。 The present invention relates to a wrench, and in particular to a wrench having the ability to extend and shorten to change the overall length when the wrench is operated.
在不少產業中都會利用螺栓、螺帽作為構件的組裝,而為了轉動螺栓、螺帽等有扳手(例如開口扳手、梅花扳手、活動扳手等)直接驅動,或是扳手(套筒扳手、氣動扳手、電動扳手)轉接套筒驅動等。 In many industries, bolts and nuts are used as components for assembly. In order to rotate the bolts and nuts, there are wrenches (such as open-end wrenches, torx wrenches, adjustable wrenches, etc.) for direct driving, or wrenches (socket wrenches, pneumatic wrenches, etc.) Wrench, electric wrench) adapter socket drive, etc.
常見的扳手整體長度都是固定尺寸,在特定情況例如裝置/結構深處或狹小空間等難以操作的工作空間區域,為了因應上述工作情況,選擇適當扳手長度是購買的考量因素,如果是經常性需要外出進行維護修繕,且需要攜帶多種長度尺寸的扳手,此舉不僅增加添購成本,攜帶上增加重量外,對於用戶體力負荷也是一種考驗,甚至影響工作效率。 The overall length of common wrenches is fixed. In certain situations, such as difficult-to-operate workspace areas deep in the device/structure or in small spaces, in order to cope with the above working conditions, choosing the appropriate wrench length is a consideration when purchasing. If it is a frequent use You need to go out for maintenance and repairs, and you need to carry wrenches of various lengths and sizes. This not only increases the purchase cost, but also increases the weight of carrying. It is also a test on the user's physical load and even affects work efficiency.
目前業界開發了可以調節整體扳手長度,例如台灣新型M429564、中國大陸發明CN111975699B、美國發明公開US20170312906A1,主要是利用外套管套接在內接管,調整長度時讓內接管、外套管兩者朝彼此靠近的方向軸向滑移時呈縮短樣貌,兩者朝彼此遠離的方向軸向滑移時呈伸長樣貌。 At present, the industry has developed wrenches that can adjust the overall length, such as Taiwan's new M429564, Mainland China's invention CN111975699B, and the United States' invention publication US20170312906A1. They mainly use the outer sleeve to sleeve the inner pipe. When adjusting the length, the inner pipe and the outer sleeve are closer to each other. When they slide axially in the direction of each other, they appear to be shortened, and when they slide axially away from each other, they appear to be elongated.
然而,上述調節扳手拉伸整體長度時,外套管與內套管兩者的接觸位置(面積)會逐漸變少,以致施加在扳手的作用力需要由兩者接觸位置承當,不僅受力過度集中有結構強度不足的疑慮,也容易在此處發生鬆動現象甚至產生操作上的異音。對此相關業者,必須針對上述扳手進行結構上改進之必要。 However, when the above-mentioned adjusting wrench stretches the entire length, the contact position (area) between the outer casing and the inner casing will gradually decrease, so that the force exerted on the wrench needs to be borne by the contact position between the two. Not only is the force excessively concentrated, There is concern that the structural strength is insufficient, and loosening may easily occur here or even abnormal noise may occur during operation. Relevant manufacturers must make structural improvements to the above-mentioned wrenches.
本發明提供一種伸縮扳手,包括有:外管,其具有沿該外管軸向設置的滑孔;該外管具有彼此呈相反方向的第一端與第二端;外套環,其具有軸向設置的套接孔以及相通該套接孔的加強孔,該外套環的該套接孔套設於該外管的該第一端;與內桿,其包括有工作部以及連接該工作部的桿段;該桿段環設有外環槽,該外環槽套設有彈性墊圈;該桿段活動滑設於該滑孔及該加強孔,且該彈性墊圈被該滑孔接觸下壓縮;而該工作部外露於該第一端外側。 The invention provides a telescopic wrench, which includes: an outer tube, which has a sliding hole arranged along the axial direction of the outer tube; the outer tube has a first end and a second end in opposite directions to each other; and an outer ring, which has an axial direction. A socket hole and a reinforced hole connected to the socket hole are provided. The socket hole of the outer ring is sleeved on the first end of the outer tube; and the inner rod includes a working part and a connecting rod connecting the working part. Rod segment; the rod segment ring is provided with an outer ring groove, and the outer ring groove is equipped with an elastic washer; the rod segment is movably slidably installed in the sliding hole and the reinforced hole, and the elastic washer is compressed by contact with the sliding hole; The working part is exposed outside the first end.
本發明提供另一種伸縮扳手,包括:外管,其具有沿該外管軸向設置的滑孔;該外管具有彼此呈相反方向的第一端與第二端;該外管於該第一端設置有連通該滑孔的安置孔;內套環,其相反兩端分別為穿入段與外置段;該穿入段插設於該安置孔,而該外置段位於該第一端外側;該內套環具有軸向貫穿該穿入段與該外置段的加強孔,又該加強孔連通該滑孔;與內桿,其包括有工作部以及連接該工作部的桿段,該桿段活動滑設於該滑孔及該加強孔,且該彈性墊圈被該滑孔接觸下壓縮;而該工作部外露於該外置段的外側。 The present invention provides another telescopic wrench, including: an outer tube with a sliding hole arranged along the axial direction of the outer tube; the outer tube has a first end and a second end in opposite directions to each other; the outer tube is located on the first The end is provided with a mounting hole connected to the sliding hole; the inner collar has a penetrating section and an external section at its opposite ends; the penetrating section is inserted into the mounting hole, and the external section is located at the first end On the outside; the inner collar has a reinforced hole that axially penetrates the penetration section and the external section, and the reinforced hole is connected to the sliding hole; and the inner rod includes a working part and a rod section connected to the working part, The rod section is movably slidably mounted on the sliding hole and the reinforcing hole, and the elastic washer is compressed under contact with the sliding hole; and the working part is exposed outside the external section.
透過上述結構配合下,外套環、內套環能穩固結合在外管(第一端),且加強孔提供內桿的桿段外周側接觸下,外套環、內套環形成了與內桿、外管兩者的外部輔助套接結構;如此提供伸縮扳手於操作使用時,可以改善過 往習知結構容易有鬆動現象以及發生異音,更進一步提升操作時承受作用力的結構強度。 Through the cooperation of the above structures, the outer ring and the inner ring can be firmly combined with the outer tube (first end), and the reinforced holes provide contact with the outer peripheral side of the rod section of the inner rod. The outer ring and the inner ring form a connection with the inner rod and the outer tube. The external auxiliary socket structure between the pipe and the pipe; thus providing a telescopic wrench during operation can improve the process. In the past, conventional structures were prone to loosening and abnormal noises, which further improved the structural strength to withstand the force during operation.
除此之外,彈性墊圈可受力壓縮變形特性,提供推、拉外管或內桿調節伸縮扳手長度時,形成一種手動操作動作阻尼順暢感外,更能減少外界異物、雜質進入影響伸縮扳手調節整體長度的運作。 In addition, the elastic washer can compress and deform under force, providing a smooth damping feel when pushing or pulling the outer tube or inner rod to adjust the length of the telescopic wrench. It can also reduce the impact of external foreign matter and impurities entering the telescopic wrench. Adjust the overall length of the operation.

The working
進一步詳細說明本發明伸縮扳手1細部特徵以及相關構件的組配關係。該外套環200具有抵接面230位於該套接孔210與該加強孔220之間,且該抵接面230係與該外管100的該第一端101端面相接觸。前述抵接面230與套接孔210的孔壁以及加強孔220的孔壁呈相連接型態,如此增加外套環200於桿段320以及外管100的接觸部位,提供伸縮扳手1被操作使用時結構穩定性。
The detailed features of the
請參閱第六圖所示,該桿段320於其外周側設有側槽323,另以一彈性件324的兩端分別彈抵該側槽323與該珠體325,以致該珠體325滾動接觸於該滑孔110。前述側槽323係未貫穿該桿段320的徑向方向,且該側槽323位置係位於桿段320相連工作部310的相反端;又彈性件324係以彈簧為例,而前述珠體325以金屬球為例;據以提供調節伸縮扳手1整體長度時操作穩定性。
Please refer to the sixth figure. The
請參閱第一、七至十一圖所示,該桿段320於其外周側沿該桿段320的軸向方向設置有滑槽326,且該滑槽326沿該滑槽326的軸向方向間隔設置有定位凹327;該外管100於其外周側設置有連通該滑孔110的側孔120;該伸縮扳手1進一步包括有控制環400並活動套置於該外管100並位於該側孔120的外側位置,且該控制環400的內推環面410位於該側孔120的外側位置,且該內推環面410限制控制球510活動於該側孔120避免從該側孔120向外脫離,以致該控制球510定位於其中一定位凹327,即該控制球510部分位於該側孔120以及部分位於定位凹327。透過上述配置下,提供伸縮扳手1調節整體長度後的定位以及多段尺寸的選擇。
Please refer to Figures 1, 7 to 11. The
另外,該控制環400設有第一內閃孔420與第二內閃孔430,前述內推環面410位於該第一內閃孔420與該第二內閃孔430之間,而該外管100的周側套

In addition, the
本實施例中,該外管100的外周側套設有第二限制件140並與該第一限制件130有間隔;當推動該控制環400朝向第一端101的方向位移時,該第二限制件140與該控制環400的第二限制面450相接觸,進而限制該控制環400從該第一端101方向向外脫離該外管100。前述第二限制件140係以C型扣為例。
In this embodiment, the outer circumferential side of the
圖式中第八至十一圖所表示伸縮扳手1的長度調節,主要是以一手握持外管100,而另一手拉動內桿300的工作部310朝遠離外管100方向為例。亦可一手握持內桿300的工作部310,另一手拉動外管100朝遠離內桿300的方向;或是雙手分別拉動外管100與內桿300的工作部310朝彼此的反方向拉動。
The length adjustment of the
請參閱第七圖所示,該外套環200設有閃避孔240並與該套接孔210相通,而該控制環400一端係常態伸入該閃避孔240內,且該外套環200未與該控制環400接觸,如此不會影響該控制環400的位移動作。
Please refer to the seventh figure, the
請配合參閱第十二至十四圖所示為本發明另一實施例,其不同於上述實施例在於:該外管100於第一端101設置有連通該滑孔110的安置孔160;內套環600,其相反兩端分別為穿入段610與外置段620;該穿入段610插設於該安置孔160,而該外置段620位於該第一端101外側;該內套環600具有軸向貫穿該穿入
