Description
本發明係與車輛保修工具有關，特別是關於一種適於對開環狀支撐座進行擴張之擴張工具。The present invention relates to vehicle maintenance tools, and in particular to an expansion tool suitable for expanding a split-ring support seat.
我國第M352438號及第M597208號新型專利前案中分別揭露了一種可用以對開環狀支撐座進行擴張之工具，渠等工具乃係分別藉由二懸臂插接於支撐座之結合孔中，使工具與支撐座彼此間相對位置受到定位，並同步地使一分隔元件位於支撐座之環狀開口中，再將螺桿之角位移改變為驅使該分隔元件移動之直線位移，進而由該分隔元件從環狀開口處對該支撐座施加擴張之力，以擴張該支撐座之內徑，使得原本結合於該支撐座中之外部元件得以被分離。my country's new patents No. M352438 and M597208 respectively disclose a tool that can be used to expand the open-ring support base. The tools are inserted into the combination holes of the support base through two cantilevers, so that The tool and the support base are positioned relative to each other, and a separation element is synchronously located in the annular opening of the support base, and then the angular displacement of the screw is changed into a linear displacement that drives the separation element to move, and then the separation element moves from The annular opening exerts an expansion force on the support base to expand the inner diameter of the support base, so that the external components originally combined in the support base can be separated.
上開專利前案所揭之技術固可達成對支撐座進行擴張之效果，惟其構造過於複雜，使得其在使用上甚為不便，除需先將原本用以鎖固支撐座環狀開口之結合螺栓予以卸除，始能提供上開習知工具之懸臂插接之構造外，亦必需有較大之工作空間始能順利操作，顯仍未臻於良善。The technology disclosed in the previously issued patent case can achieve the effect of expanding the support base, but its structure is too complicated, making it very inconvenient to use. In addition to needing to first lock the annular opening of the support base, the combination The bolts must be removed to provide a cantilevered connection structure for opening conventional tools. A larger working space is also required for smooth operation, which shows that it has not yet reached perfection.
因此，本發明之主要目的即係在提供一種擴張工具，其構造精簡且可於狹隘空間中進行操作，更可在作為擴張標的之支撐座的結合元件僅鬆脫但未卸除之狀態下進行對開環狀支撐座之擴張作業，進一步地增加該擴張工具之實用性。Therefore, the main purpose of the present invention is to provide an expansion tool that has a streamlined structure and can be operated in a narrow space. It can also be operated in a state where the connecting element of the support base used as the expansion target is only loose but not removed. The expansion operation of the open ring support seat further increases the practicality of the expansion tool.
緣是，為達成上述目的，本創作所提供之擴張工具乃係包括二相對配置的頂抵部，而且各該頂抵部更分別具有二彼此相隔開來之靠抵凸體及一介於各該靠抵凸體間之避讓缺口，其中，當該二頂抵部***於一外部之支撐座的一結合元件鬆開時所形成之一縫隙中時，係利用該避讓缺口容置仍位於該縫隙中之該結合元件，使得各該靠抵凸體能分別避開並越過該結合元件，而深入該縫隙中，得以令該二頂抵部能確實地分別迫抵在該支撐座於該縫隙中的二相對內壁面，據此，本案相較於習知技術能簡便且快速地進行擴張作業，並更可適於狹小的工作空間來操作使用。The reason is that, in order to achieve the above purpose, the expansion tool provided by this invention includes two oppositely arranged abutting parts, and each of the abutting parts has two abutting protrusions that are spaced apart from each other and a between each of the abutting protrusions. The avoidance gap between the abutting protrusions is used. When the two abutting parts are inserted into a gap formed when a coupling element of an external support seat is loosened, the escape gap is used to accommodate the gap that is still located in the gap. The coupling element allows each of the abutting protrusions to avoid and cross the coupling element respectively, and penetrate deep into the gap, so that the two resisting parts can reliably press against the support seat in the gap. According to the two opposite inner wall surfaces, this case can perform expansion operations more easily and quickly compared with the conventional technology, and is more suitable for operation in a narrow working space.
具體來說，該擴張工具還包括一身部、一固設於該身部上之固定部、一可移動地設於該身部上之活動部及一設於該身部上之驅動部，並且，該二頂抵部係兩兩相對地分別設於該固定部及該活動部上，藉此，該驅動部得以驅動該活動部於一靠近該固定部之第一位置與一遠離該固定部之第二位置間移動，據以調整該二頂抵部彼此之間的距離，以進行擴張作業之用。Specifically, the expansion tool further includes a body, a fixed part fixed on the body, a movable part movably provided on the body and a driving part provided on the body, and , the two resisting parts are respectively provided on the fixed part and the movable part opposite each other, whereby the driving part can drive the movable part to a first position close to the fixed part and a first position away from the fixed part The movement between the second positions is used to adjust the distance between the two resisting parts for expansion operations.
更進一步地，為使該活動部於該身部上受導引地移動，係使該身部具有一長形之柱體及一滑動空間，而該滑動空間係設於該柱體長軸之一端並沿該柱體之長軸延伸一預定之距離，並使該活動部可於該滑動空間中在該第一位置與該第二位置間移動。Furthermore, in order to allow the movable part to move guided on the body, the body is provided with a long cylinder and a sliding space, and the sliding space is provided on the long axis of the cylinder.

Furthermore, the movable part includes a sliding seat that is slidably disposed in the sliding space and can linearly reciprocate between the first position and the second position, and one of the resisting parts is integrally formed. The base is disposed on the sliding seat and protrudes from the sliding space outside the body.
而為改善該活動部的作動行程的精確度及荷重量，該活動部係螺接於該驅動部之一局部周側環設有螺紋之桿體上，以利用該桿體轉動來帶動該活動部位移。In order to improve the accuracy and load capacity of the actuating stroke of the movable part, the movable part is screwed to a rod body with threads on a part of the peripheral side of the driving part, so as to utilize the rotation of the rod body to drive the movement. Partial displacement.
更進一步來說，該身部係更包含有一開口及一通孔，兩者係彼此相隔開來且同軸地設於該柱體兩端，並使該開口與該通孔彼此間經由該滑動空間而連通，以供該桿體穿置。Furthermore, the body further includes an opening and a through hole, which are spaced apart from each other and coaxially provided at both ends of the cylinder, and the opening and the through hole are connected to each other through the sliding space. Connected for the rod body to pass through.
在一實施例中，該桿體以桿軸兩端側分別為第一端及第二端，且該桿體伸出該身部外之第二端更固設有一驅動端體，便於使用者利用一外部手工具施力於該驅動端體上，使該驅動端體相對該身部轉動，並連動該桿體樞轉。In one embodiment, the two ends of the rod shaft are respectively the first end and the second end, and the second end of the rod extending out of the body is further provided with a driving end body, which is convenient for the user. An external hand tool is used to apply force on the driving end body, so that the driving end body rotates relative to the body and links the rod body to pivot.
為了限制該桿體相對該身部沿該柱體長軸方向位移，並允許該桿體相對該柱體旋轉轉動，該通孔係呈階狀孔，而該桿體之第二端係具有一與該通孔相互補之階狀桿身，並同軸穿設於該通孔中；再者，該固定部面對該身部之一側設有一凹入，用以容置該桿體呈錐狀之該第一端，據以達到適當限制該桿體作動方式的目的。In order to limit the displacement of the rod relative to the body along the long axis of the cylinder and allow the rod to rotate relative to the cylinder, the through hole is a stepped hole, and the second end of the rod has a A stepped shaft complementary to the through hole is coaxially inserted into the through hole; furthermore, a recess is provided on one side of the fixed portion facing the body to accommodate the tapered shape of the shaft. The first end is shaped to achieve the purpose of appropriately restricting the action mode of the rod body.
在一實施例中，該滑座更貫設有一與該通孔同軸之螺孔，以與該桿體之該第一端相螺接。In one embodiment, the sliding seat is further provided with a screw hole coaxial with the through hole for screwing with the first end of the rod body.
