Description
本發明係有關一種活塞式氣密裝置，尤指一種將條狀活塞體設置於條狀中空體內部，且利用充氣與抽氣而令條狀活塞體之伸縮部外伸或是回縮，進而達到氣密狀態或是解除氣密之設計者。The present invention relates to a piston type airtight device, in particular to a strip-shaped piston body disposed inside a strip-shaped hollow body, and using an inflation and suction to extend or retract the expansion and contraction portion of the strip-shaped piston body, thereby A designer who achieves airtightness or releases airtightness.
按，如第一圖所示，連結至充氣與抽氣泵(圖未示)之膨脹式膠條(10)為普遍使用之氣密裝置，在此以裝設於曝光框(20)說明其氣密原理，充氣膨脹時可讓曝光框(20)維持氣密，抽氣萎縮後則解除其氣密性；但因膨脹式膠條(10)之接合面稍有瑕疵就會造成氣壓洩漏，無法充氣膨脹而提供高度氣密之環境，故造成膨脹式膠條(10)有氣密性不穩定之問題，進而必須時常予以更換，乃成為氣密設計所亟待解決之問題。According to the first figure, the expansion strip (10) connected to the inflation and air pump (not shown) is a commonly used airtight device, and the gas is installed in the exposure frame (20). The principle of denseness, the inflation frame can maintain the airtightness of the exposure frame (20), and the airtightness is released after the suction is atrophied; however, due to the slight flaw of the joint surface of the expansion type rubber strip (10), the air pressure leaks, and the air pressure cannot be The inflation and expansion provide a highly airtight environment, so that the expansion strip (10) has the problem of unstable airtightness, and must be replaced frequently, which is a problem to be solved in the airtight design.
本發明之主要目的，係欲提供一種活塞式氣密裝置，而具有氣密性穩定之功效。The main object of the present invention is to provide a piston type airtight device which has the effect of airtight stability.
為達上述功效，本發明之結構特徵，係包括有：一條狀中空體，底緣形成有穿槽；一條狀活塞體，設置於該條狀中空體內部，而相對該穿槽形成有伸縮部；以及一氣管，一端連結至該條狀中空體內部，另端則連結至充氣與抽氣泵，而對該條狀活塞體頂緣上方之空間充氣 與抽氣，俾令該條狀活塞體之伸縮部外伸或是回縮者。In order to achieve the above-mentioned effects, the structural features of the present invention include: a hollow body having a bottom edge formed with a through groove; and a strip-shaped piston body disposed inside the strip-shaped hollow body, and a telescopic portion is formed with respect to the through-groove And an air pipe, one end is connected to the inside of the strip hollow body, and the other end is connected to the inflation and air pump, and the space above the top edge of the strip piston body is inflated With the pumping, the extension of the strip-shaped piston body is extended or retracted.
此外，進一步相對該條狀活塞體頂緣設置有複數個彈性體。又，該條狀中空體進一步於頂緣設置有定位膠條。Further, a plurality of elastic bodies are further disposed with respect to the top edge of the strip-shaped piston body. Further, the strip-shaped hollow body is further provided with a positioning strip at the top edge.
首先，請參閱第二圖所示，本發明係包括有：一條狀中空體(30)，底緣形成有穿槽(31)，並進一步於頂緣設置有定位膠條(32)，俾以提供氣密性更佳之裝設面；一條狀活塞體(40)，設置於該條狀中空體(30)內部，而相對該穿槽(31)形成有伸縮部(41)，該伸縮部(41)乃可外伸(氣密狀態)或是回縮(解除氣密)；以及一氣管(50)，一端連結至該條狀中空體(30)內部，另端則連結至充氣與抽氣泵(圖未示)，而對該條狀活塞體(40)頂緣上方之空間充氣與抽氣，俾令該條狀活塞體(40)之伸縮部(41)外伸或是回縮者。First, referring to the second figure, the present invention includes a strip-shaped hollow body (30), the bottom edge is formed with a through groove (31), and further a positioning strip (32) is disposed on the top edge, Providing a more airtight mounting surface; a strip-shaped piston body (40) disposed inside the strip-shaped hollow body (30), and a telescopic portion (41) formed with respect to the through-groove (31), the telescopic portion ( 41) can be extended (airtight state) or retracted (unsealed); and a trachea (50), one end is connected to the inside of the strip hollow body (30), and the other end is connected to the inflation and air pump (not shown), and the space above the top edge of the strip piston body (40) is inflated and evacuated, so that the expansion and contraction portion (41) of the strip-shaped piston body (40) is extended or retracted.
此外，進一步相對該條狀活塞體(40)頂緣設置有複數個諸如彈簧之彈性體(60)，該彈性體(60)用以平衡該條狀活塞體(40)外推時所受到之摩擦力，致使將該條狀活塞體(40)外推時較為省力且敏捷，得以快速達到氣密狀態。In addition, a plurality of elastic bodies (60), such as springs, are further disposed on the top edge of the strip piston body (40), and the elastic body (60) is used to balance the external piston body (40) when it is extrapolated. The friction force causes the strip piston body (40) to be extrapolated and labor-saving, and the airtight state can be quickly achieved.
基於如是之構成，本發明利用對該條狀中空體(30)內部充氣與抽氣，而令該條狀活塞體(40)之伸縮部(41)外伸或是回縮，進而達到氣密狀態或是解除氣密之活塞式氣密設計，構件間之密合性極佳，並不會產生氣壓洩漏之情事，具有氣密性穩定之功效。Based on the configuration, the present invention utilizes the inside of the strip-shaped hollow body (30) to inflate and evacuate, and the telescopic portion (41) of the strip-shaped piston body (40) is extended or retracted to achieve airtightness. The state is either a gas-tight piston-type airtight design, and the adhesion between the components is excellent, and there is no leakage of air pressure, which is airtight and stable.
