Description
本發明與有關一種管鉗，尤指一種易解鎖扣的管鉗。 The invention relates to a pipe wrench, in particular to a pipe wrench with an easy release button.
請參閱圖1A、1B及1C，圖1A、1B係為習知管鉗作動的剖面示意圖，圖1C係為習知管鉗齒塊及嚙齒部的放大圖。習知管鉗1包含第一鉗體11、第二鉗體12及按壓件13，按壓件13穿過彈性元件14、第一鉗體11及第二鉗體12，其中第一鉗體11及第二鉗體12係為交叉樞設。第一鉗體11上設有一貫穿之齒槽，齒槽內左、右兩側分別設有多數齒塊15。第二鉗體12包含一穿孔，第二鉗體12以穿孔正對於第一鉗體11齒槽，並藉由按壓件13穿過該穿孔與第一鉗體11交叉相疊。按壓件13包含第一結合件13A及第二結合件13B，第二結合件13B上具有對應多數齒塊15的嚙齒部16，以便於藉由嚙齒部16與多數齒塊15齧合。 Please refer to FIGS. 1A, 1B, and 1C. FIGS. 1A and 1B are schematic cross-sectional views of the operation of a conventional pipe wrench, and FIG. 1C is an enlarged view of a tooth block and a rod portion of the conventional pipe wrench. The conventional pipe wrench 1 includes a first jaw body 11, a second jaw body 12, and a pressing member 13. The pressing member 13 passes through the elastic element 14, the first jaw body 11, and the second jaw body 12, wherein the first jaw body 11 and The second forceps body 12 is pivotally arranged. The first pliers body 11 is provided with a penetrating tooth groove, and the left and right sides of the tooth groove are respectively provided with a plurality of tooth blocks 15. The second forceps body 12 includes a perforation. The second forceps body 12 faces the tooth gap of the first forceps body 11 with the holes, and passes through the holes through the pressing member 13 to overlap and overlap the first forceps body 11. The pressing member 13 includes a first coupling member 13A and a second coupling member 13B. The second coupling member 13B has a toothing portion 16 corresponding to the plurality of tooth blocks 15 so that the toothing portion 16 can be engaged with the plurality of tooth blocks 15.
承上所述，由圖1B可以看出齒塊15與互相齧合的嚙齒部16具有相對應的長邊15L1、16L1及短邊15L2、16L2，長邊15L1、16L1係為貫穿齒槽的方向，短邊15L2、16L2係為沿著第一鉗體11本體的方向。習知管鉗1則是藉由使用者按壓按壓件13，使得第二結合件13B的嚙齒部16脫離第一鉗體11的齒塊15，以便於將按壓件13移動至齒槽另一位置，進一步調整第一鉗體11及第二鉗體12之間的開口大小。 As mentioned above, it can be seen from FIG. 1B that the tooth block 15 and the meshing rod portion 16 have corresponding long sides 15L1 and 16L1 and short sides 15L2 and 16L2, and the long sides 15L1 and 16L1 are the directions penetrating the tooth grooves. The short sides 15L2 and 16L2 are along the direction of the body of the first forceps 11. In the conventional pipe wrench 1, the user presses the pressing member 13 so that the rod portion 16 of the second coupling member 13B is separated from the tooth block 15 of the first jaw body 11 in order to move the pressing member 13 to another position of the tooth groove. , Further adjust the size of the opening between the first jaw body 11 and the second jaw body 12.
然而，由於按壓按壓件13使得第二結合件13B的嚙齒部16脫離第一鉗體11齒塊15的按壓距離係與齒塊15與嚙齒部16長邊15L1、16L1的長度相關，當長邊長度越長時，按壓距離越長，將使得使用者必須花費更多力氣與時間方能將按壓件13移動至齒槽另一位置，因此，也造成使用者在使用上的不便。 However, the pressing distance caused by pressing the pressing member 13 to disengage the rod portion 16 of the second coupling member 13B from the tooth block 15 of the first pliers body 11 is related to the length of the long sides 15L1 and 16L1 of the tooth block 15 and the rod portion 16. When the length is longer, the longer the pressing distance is, the more effort and time is required for the user to move the pressing member 13 to another position of the alveolar groove. Therefore, the user is also inconvenienced in use.
據此，如何提供一種可快速變換按壓件的位置，以進一步快速調整第一鉗體及第二鉗體之間開口大小的管鉗已成為目前急需研究的課題。 According to this, how to provide a pipe wrench that can quickly change the position of the pressing member to further quickly adjust the size of the opening between the first jaw body and the second jaw body has become an urgent research topic.

The easy-release buckle pipe wrench 2 includes a first jaw body 21, a second jaw body 22, and a control member 26. The first jaw body 21 has a first jaw portion 211 and a first grip portion 212 at both ends, and an actuating portion 23 is provided between the first jaw portion 211 and the first grip portion 212. The tooth groove 24 is provided with a plurality of triangular tooth blocks 25 on the left and right sides in the tooth groove 24, respectively. The second jaw body 22 has a second jaw portion 221 and a second grip portion 222 at both ends, and a perforation 220 is provided between the second jaw portion 221 and the second grip portion 222. The tooth grooves 24 of the first forceps body 21 intersect and overlap the first forceps body 21. The control member 26 is provided in the actuating portion 23 through the perforation. The control member 26 includes a pressing member 261, an elastic member 262, a first coupling member 263, and a second coupling member 264. Press The member 261 has an opening 260. Two ends of the elastic element 262 are in contact with the pressing member 261 and the first pliers 21, respectively. The first coupling member 263 passes through the opening 260 and the elastic element 262 of the pressing member 261. The second coupling member 264 has a rod portion 2641 corresponding to the plurality of triangular tooth blocks 25, and is combined with the first coupling member 263 through the perforation and the actuating portion 23. The rod portion 2641 is engaged with the majority of the triangular tooth blocks 25, and the rod portion 2641 The position can be moved to another position of the tooth groove 24 by pressing the pressing member 261 to escape from most of the triangular tooth blocks 25, thereby changing the opening size between the first jaw body 21 and the second jaw body 22. In addition, a length 25L2 of a long side extending in the radial direction of each triangular tooth block 25 is longer than a length 25L1 of a short side extending in the axial direction.
承上所述，嚙齒部2641沿徑向延伸的一斜邊的長度264L2長於沿軸向延伸的一直邊的長度264L1。 As mentioned above, the length 264L2 of the oblique side extending in the radial direction of the rod portion 2641 is longer than the length 264L1 of the straight side extending in the axial direction.
進一步而言，由於按壓按壓件261而使嚙齒部2641脫離多數三角形齒塊25的距離，與嚙齒部2641及多數三角形齒塊25在軸向的長度25L1、264L1有關，因此，當使用者按壓按壓件261，使得第二結合件264的嚙齒部2641脫離第一鉗體21的三角形齒塊25，以便於將按壓件261移動至齒槽24的另一位置，進一步調整第一鉗部211及第二鉗部221之間的開口大小時，因為在按壓方向(亦即軸向)上的長度25L1、264L1距離較短，因此可達到快速變換按壓件261的位置，進一步快速調整第一鉗部211及第二鉗部221之間開口的大小。 Further, the distance that the rod portion 2641 is separated from the majority of the triangular tooth blocks 25 by pressing the pressing member 261 is related to the axial lengths 25L1 and 264L1 of the rod portion 2641 and the majority of the triangular tooth blocks 25. Therefore, when the user presses the button Piece 261, so that the rod portion 2641 of the second coupling piece 264 is separated from the triangular tooth block 25 of the first jaw body 21, so as to move the pressing member 261 to another position of the tooth groove 24, and further adjust the first jaw portion 211 and the first jaw portion 211 When the opening between the two jaws 221 is large, the distances 25L1 and 264L1 in the pressing direction (that is, the axial direction) are short, so the position of the pressing member 261 can be quickly changed, and the first jaw 211 can be adjusted quickly. And the size of the opening between the second jaw portion 221.
請參閱圖4A及圖4B，其係為本發明易解鎖扣管鉗與習知管鉗在按壓距離上的比較圖。在相同結構的情況下，如圖4A所示，由於本案易解鎖扣管鉗2在按壓方向上的長度25L1、264L1距離較短，亦即脫離距離H1較短，因此可達到快速脫離的效果。相較於習知管鉗1，由於其在按壓方向上的長度16L1距離較長，亦即脫離距離H2較長，因此，習知的管鉗1必須在按壓方向上花費較多的時間及距離，方能達到變換按壓件13位置的效果。 Please refer to FIG. 4A and FIG. 4B, which are comparison diagrams of the pressing distance between the easy-release pipe clamp and the conventional pipe clamp according to the present invention. In the case of the same structure, as shown in FIG. 4A, since the lengths 25L1 and 264L1 in the pressing direction of the easy-to-unlock pipe clamp 2 in this case are relatively short, that is, the detachment distance H1 is short, the effect of rapid detachment can be achieved. Compared to the conventional pipe wrench 1, the distance of 16L1 in the pressing direction is longer, that is, the separation distance H2 is longer. Therefore, the conventional pipe wrench 1 must spend more time and distance in the pressing direction. , To achieve the effect of changing the position of the pressing member 13.
此外，由於在按壓方向上的長度25L1、264L1距離較短，因此，本發明易解鎖扣的管鉗2整體元件的厚度相較於習知 管鉗1的厚度亦可較薄。 In addition, since the lengths 25L1 and 264L1 in the pressing direction are relatively short, the thickness of the overall component of the pipe wrench 2 of the easy-release buckle of the present invention is compared with the conventional The pipe wrench 1 may also be thin.
再者，易解鎖扣的管鉗2更包含一墊片265，設置於彈性元件262與第一鉗體21之間。按壓件261具有一容置空間，彈性元件262設置於按壓件261的容置空間中。 Furthermore, the easy-to-release pipe wrench 2 further includes a gasket 265 disposed between the elastic element 262 and the first jaw body 21. The pressing member 261 has an accommodating space, and the elastic element 262 is disposed in the accommodating space of the pressing member 261.
綜上所述，本發明易解鎖扣管鉗藉由在按壓方向(軸向)上設計為相比於徑向上較短的長度，因此，便於使用者可以較短的按壓距離及時間達到嚙齒部2641與齒塊25快速脫離的效果，因而可快速變換按壓件在齒槽24中的位置，進一步快速調整第一鉗部211及第二鉗部221之間開口的大小。此外，藉由在按壓方向(軸向)上較短長度的設計，亦可使整體易解鎖扣管鉗的厚度薄型化。 To sum up, the easy-to-unlock pipe clamp of the present invention is designed to be shorter in length in the pressing direction (axial direction) than in the radial direction. Therefore, it is convenient for the user to reach the rod portion in a short pressing distance and time. The effect of rapid disengagement between 2641 and the tooth block 25 can quickly change the position of the pressing member in the tooth groove 24, and further quickly adjust the size of the opening between the first jaw portion 211 and the second jaw portion 221. In addition, by designing a shorter length in the pressing direction (axial direction), the thickness of the overall easy-to-unlock pipe clamp can also be reduced.
