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 is related to vehicle maintenance tools, in particular to an expansion tool suitable for expanding split-ring support seats.
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 No. M352438 and No. M597208 New Patents previously disclosed a tool that can be used to split the ring-shaped support seat for expansion. The tools such as the cantilever are respectively inserted into the joint hole of the support seat by two cantilever arms, so that the relative positions of the tool and the support seat are positioned, and simultaneously a partition element is positioned in the ring-shaped opening of the support seat, and then the angular displacement of the screw is changed into a linear displacement that drives the partition element to move. An expansion force is applied to the support base to expand the inner diameter of the support base, so that the external elements 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 above-mentioned patent can achieve the effect of expanding the support seat, but its structure is too complicated, which makes it very inconvenient to use. In addition to firstly removing the coupling bolts originally used to lock the annular opening of the support seat to provide the cantilever insertion structure of the conventional tools above, a large working space is required to operate smoothly, which is obviously not perfect.
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, which has a simple structure and can be operated in a narrow space. It is also possible to perform the expansion operation of the split ring-shaped support seat under the condition that the coupling element of the support seat as the expansion target is only loosened but not removed, so as to further increase the practicability 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-mentioned purpose, the expansion tool provided by this creation is composed of two opposing abutting parts, and each of the abutting parts has two abutting protrusions spaced apart from each other and an avoidance gap between each of the abutting protrusions. By avoiding and passing over the coupling element, and going deep into the gap, the two abutting portions can be respectively pressed against the two opposite inner walls of the support base in the gap. According to this, compared with the prior art, the expansion operation can be performed easily and quickly in this case, and it is more suitable for operation and use in a narrow working space.

The part is pushed into the recess 22 of the fixing part 20 . In addition, the second end 412 of the rod body 41 has a stepped shaft complementary to the through hole 14 and coaxially passes through the through hole 14, thereby restricting the displacement of the rod body 41 relative to the body 10 along the long axis of the cylinder 11 and allowing the rod body 41 to rotate relative to the cylinder 11.
接著，該桿體41之第二端412的端部係伸出該身部10外，而該驅動端體42係固設於該桿體41伸出該身部10外之第二端412上。Then, the end of the second end 412 of the rod body 41 protrudes out of the body 10 , and the driving end body 42 is fixed on the second end 412 of the rod body 41 protruding out of the body 10 .
該二頂抵部50係兩兩相對且分別一體成形地各自設於該座體21及該滑座31上，而位於該滑座31上之該頂抵部50係顯露於該身部10之外，在本例中，各該頂抵部50更分別具有二彼此相隔開來之靠抵凸體51及一介於各該靠抵凸體51間之避讓缺口52。The two abutting portions 50 are opposite to each other and integrally formed respectively on the seat body 21 and the sliding seat 31, and the abutting portions 50 on the sliding seat 31 are exposed outside the body portion 10.
藉由上述構件之組成，本創作之該擴張工具於具體操作使用過程如圖5所示，首先，當該滑座31位於該第一位置上時，係使該二頂抵部50彼此相向之側面彼此貼合，而可使該二頂抵部50得以同時***於一外部之開環狀支撐座60的一結合元件61鬆開時所形成之一縫隙62中，並得以該避讓缺口52容置仍位於該縫隙62中之該結合元件61，使得各該靠抵凸體51能分別避開並越過該結合元件61，而深入該縫隙62中，得以令該二頂抵部50能確實地分別迫抵在該支撐座60於該縫隙62中的二相對內壁面63上。By the composition of the above-mentioned components, the specific operation and use process of the expansion tool of the present invention is shown in Figure 5. First, when the sliding seat 31 is located at the first position, the sides of the two abutting parts 50 facing each other are made to fit together, so that the two abutting parts 50 can be simultaneously inserted into a gap 62 formed when a coupling element 61 of an external open ring support seat 60 is loosened, and the avoidance gap 52 can accommodate the coupling element 6 that is still in the gap 62 1, so that each of the abutment projections 51 can respectively avoid and pass over the coupling element 61, and go deep into the gap 62, so that the two abutting parts 50 can be pressed against the two opposite inner wall surfaces 63 of the support seat 60 in the gap 62 respectively.
接著，使用者係利用一外部手工具（圖式中未顯示）施力於該驅動端體42上，使該驅動端體42相對該身部10轉動，並連動該桿體41樞轉，然而，因該桿體41與該滑座31彼此之間屬螺接關係，使該桿體41旋轉的過程係得以驅動該滑座31於該滑動空間121中移動，而使該滑座31由該第一位置移動至該第二位置，即使得該二頂抵部50彼此間相隔開來，藉以撐開該支撐座60之縫隙62。Then, the user uses an external hand tool (not shown in the drawings) to exert force on the driving end body 42, so that the driving end body 42 rotates relative to the body 10, and the rod body 41 is pivoted. The abutting portions 50 are spaced apart from each other so as to expand the gap 62 of the support base 60 .
此外，本創作另一具體使用方式如圖6所示，其係顯示該結合元件61已自該支撐座60上卸除，接著，同如前述操作方式，係先確定該滑座31位於該第一位置，以將該二頂抵部50同時***該縫隙62，亦可順利地對該支撐座60進行後續之擴張作業。In addition, another specific usage method of the present invention is shown in FIG. 6 , which shows that the coupling element 61 has been removed from the support seat 60 . Then, as in the aforementioned operation mode, it is first determined that the slide seat 31 is located at the first position, so that the two abutting portions 50 are inserted into the gap 62 at the same time, and the subsequent expansion operation of the support seat 60 can be carried out smoothly.
