該第二防漏層4具有相連接的一上防漏部41及一下防漏部42，該上防漏部41形成在該數個鍊齒3的上端，該上防漏部41的內側形成一抵接面411；該下防漏部42則形成在該數個鍊齒3的下端，該下防漏部42的外側連接該第一防漏層2，該下防漏部42的內側形成一抵接面421。該上防漏部41及下防漏部42的局部填滿各該鍊齒3的凹溝311，且該上防漏部41及下防漏部42以填注在任二相鄰鍊齒3之間的部位相連接。在設有前述輔助定位孔34的實施例中，該上防漏部41具有一延伸部412填注在設於該鍊齒3上端的輔助定位孔34中，該下防漏部42具有一延伸部422填注在設於該鍊齒3下端的輔助定位孔34中，以分別提升該上防漏部41及下防漏部42與該鍊齒3的結合穩固性，其中尤以該二輔助定位孔34呈相連通的實施例具有最佳的結合穩固性及成型良率。 The second leakage preventing layer 4 has an upper leakage preventing portion 41 and a lower leakage preventing portion 42. The upper leakage preventing portion 41 is formed at an upper end of the plurality of fastener elements 3, and the inner side of the upper leakage preventing portion 41 is formed. An abutting surface 411; the lower leakage preventing portion 42 is formed at a lower end of the plurality of fastener elements 3, and the outer side of the lower leakage preventing portion 42 is connected to the first leakage preventing layer 2, and the inner side of the lower leakage preventing portion 42 is formed Abutting surface 421. The upper leakage preventing portion 41 and the lower leakage preventing portion 42 partially fill the concave grooves 311 of the fastener elements 3, and the upper leakage preventing portion 41 and the lower leakage preventing portion 42 are filled in any two adjacent fastener elements 3. The parts are connected. In the embodiment provided with the auxiliary positioning hole 34, the upper leakage preventing portion 41 has an extending portion 412 filled in the auxiliary positioning hole 34 provided at the upper end of the element 3, and the lower leakage preventing portion 42 has an extension. The portion 422 is filled in the auxiliary positioning hole 34 provided at the lower end of the sprocket 3 to respectively improve the bonding stability of the upper leakage preventing portion 41 and the lower leakage preventing portion 42 and the sprocket 3, wherein the auxiliary The embodiment in which the positioning holes 34 are in communication has the best combination of stability and molding yield.
該第二防漏層4與該第一防漏層2可選擇為相同材質，或是使該第二防漏層4的熔點高於該第一防漏層2，以於成型該第二防漏層4時，使該第二防漏層4能與該第一防漏層2相互熔合，以提升該第二防漏層4與該第一防漏層2的結合強度及緊密性。又，任二相鄰鍊齒3之間還可藉由設置前述的凹缺313，而增加該第二防漏層4與該二鍊齒3的接觸面積，以及該第二防漏層4與該第一防漏層2的接觸面積，使該第二防漏層4與各該鍊齒3及該第一防漏層2的結合強度及緊密性更佳，同時亦可提供穩固該第二防漏層4的效果，使該第二防漏層4更不易在受到Y方向上的外力時產生裂損。再且，該第二防漏層4可以採射出成型法成型，以確保該抵接面411、421能形成平整的表面。 The second leakage preventing layer 4 and the first leakage preventing layer 2 may be selected from the same material, or the melting point of the second leakage preventing layer 4 is higher than the first leakage preventing layer 2, so as to form the second anti-drain layer 2 When the layer 4 is drained, the second leakage preventing layer 4 can be fused with the first leakage preventing layer 2 to improve the bonding strength and tightness of the second leakage preventing layer 4 and the first leakage preventing layer 2. Moreover, between the two adjacent sprocket teeth 3, the contact area of the second leakage preventing layer 4 and the two sprocket teeth 3 can be increased by providing the aforementioned recess 313, and the second leakage preventing layer 4 and The contact area of the first leakage preventing layer 2 makes the bonding strength and tightness of the second leakage preventing layer 4 and each of the sprocket 3 and the first leakage preventing layer 2 better, and can also provide the second The effect of the leakage preventing layer 4 makes it more difficult for the second leakage preventing layer 4 to be cracked when subjected to an external force in the Y direction. Further, the second leakage preventing layer 4 can be formed by injection molding to ensure that the abutting faces 411, 421 can form a flat surface.
請參照第6、7圖所示，據由前述結構，將二個前述的鍊條相對接以形成本實施例的防水拉鍊時，該二鍊條的防水鍊布各可朝其外側彎折成水平延伸，且該二鍊條可設置一拉頭5，經由拉動該拉頭5，可以使該二鍊條的數個鍊齒3形成交錯的相嚙合或分離。當該二鍊條的數個鍊齒3形成交錯的相嚙合時，藉由該第一防漏層2可以防止流體由該布帶1的一表面滲漏到另一表面；以及，由於該二鍊條的第二防漏層4的上防漏部41及下防漏部42各由內側之抵接面411、421成相對緊抵，如此，當即使有少量的流體由該二鍊條成相對緊抵的上防漏部41的抵接面411之間滲入時，也會因壓力驟降而被設於該二鍊條成相對緊抵的下防漏部42的抵接面421所攔阻，因此，本發明的防水拉鍊可以由該二鍊條的上防漏部41及下防漏部42成相對緊抵的抵接面411、421分別形成雙重防漏保護效果。 Referring to Figures 6 and 7, according to the foregoing structure, when the two aforementioned chains are connected to form the waterproof zipper of the embodiment, the waterproof chain of the two chains can be bent horizontally to the outside thereof. Extendingly, the two chains can be provided with a slider 5, and by pulling the slider 5, the plurality of sprocket teeth 3 of the two chains can be engaged or disengaged. When the plurality of sprocket teeth 3 of the two chains form a staggered phase engagement, the first leakage preventing layer 2 can prevent fluid from leaking from one surface of the tape 1 to the other surface; and, due to the two chains The upper leakage preventing portion 41 and the lower leakage preventing portion 42 of the second leakage preventing layer 4 are relatively tightly pressed by the inner abutting faces 411, 421, so that even a small amount of fluid is relatively tightly resisted by the two chains. When the contact surface 411 of the upper leakage preventing portion 41 penetrates between the contact surfaces 411 of the upper leakage preventing portion 41, the contact surface 421 of the lower leakage preventing portion 42 in which the two chains are relatively tightly resisted by the pressure drop is blocked. The waterproof zipper of the present invention can form a double leakage preventing effect by the abutting surfaces 411 and 421 which are relatively abutted by the upper leakage preventing portion 41 and the lower leakage preventing portion 42 of the two chains.
將本發明的防水拉鍊作防漏耐受程度的測試時，即使高壓流體通過其相緊抵的上防漏部41，流體壓力也會被大幅降低而無法通過其相緊抵的下防漏部42，故本發明防水拉鍊的防漏耐受程度可明顯提升，防止流體滲漏的效果極佳。 When the waterproof zipper of the present invention is tested for the degree of leakage tolerance, even if the high-pressure fluid passes through the upper leakage preventing portion 41 against which the high-pressure fluid passes, the fluid pressure is greatly reduced, and the lower leakage preventing portion that cannot be passed through the phase is prevented. Therefore, the leakage resistance of the waterproof zipper of the invention can be significantly improved, and the effect of preventing fluid leakage is excellent.
請參照第8圖，其係本發明防水拉鍊的鍊條的第二實施例，本第二實施例與第一實施例大致相同，其主要差異在於：本第二實施例的布帶1及第一防漏層2係將各鍊齒3的頭部3a及尾部3b分隔在二側，使各該鍊齒3同時由設於本體31上、下表面的二擋止牆33連接該防水鍊布，故該第二防漏層4的上防漏部41及下防漏部42之外側同連接於第一防漏層2。 Referring to FIG. 8 , which is a second embodiment of the chain of the waterproof zipper of the present invention, the second embodiment is substantially the same as the first embodiment, and the main difference is that the tape 1 and the first embodiment of the second embodiment The leakage preventing layer 2 separates the head portion 3a and the tail portion 3b of each of the fastener elements 3 on two sides, so that each of the fastener elements 3 is simultaneously connected to the waterproof chain cloth by a second blocking wall 33 provided on the upper and lower surfaces of the body 31. Therefore, the outer leakage preventing portion 41 of the second leakage preventing layer 4 and the outer side of the lower leakage preventing portion 42 are connected to the first leakage preventing layer 2 at the same time.
請參照第9圖，將二個第二實施例的鍊條相對接以形成一防水拉鍊時，同樣能使該二鍊條的第二防漏層4的上防漏部41及下防漏部42的抵接面411、421相對緊抵，其同可以達到相同的雙重防漏效果。 Referring to FIG. 9 , when the chains of the two second embodiments are connected to each other to form a waterproof zipper, the upper leakage preventing portion 41 and the lower leakage preventing portion 42 of the second leakage preventing layer 4 of the two chains can also be The abutting faces 411, 421 are relatively tight, and the same double leakage preventing effect can be achieved.
綜上所述，本發明之防水拉鍊，不僅在布帶1設有第一防漏層2可防止流體通過外，由於該鍊齒3更具有第二防漏層4，而該第二防漏層4係具有上防漏部41及下防漏部42之雙重防漏效果，因此，即使有少量的高壓流體由設於該二鍊條成相對緊抵的上防漏部41的抵接面411之間通過時，也會因壓力驟降而被成相對緊抵的下防漏部42的抵接面421所攔阻，以形成第二重防漏效果。 In summary, the waterproof zipper of the present invention not only has the first leakage preventing layer 2 disposed on the tape 1 to prevent fluid from passing through, but the sprocket 3 further has a second leakage preventing layer 4, and the second leakage preventing layer The layer 4 has a double leakage preventing effect of the upper leakage preventing portion 41 and the lower leakage preventing portion 42. Therefore, even if a small amount of high-pressure fluid is provided by the abutting surface 411 of the upper leakage preventing portion 41 which is relatively tightly provided to the two chains. When passing between, the contact surface 421 of the lower leakage preventing portion 42 which is relatively tightly pressed by the sudden drop of pressure is also blocked to form a second heavy leakage preventing effect.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention.
