[0044] like Figure 1 and Figure 2 As shown, the tightening tool for resistance welding cooling water pipe of the utility model comprises a first rod 100 and a second rod 200, and the second rod 100 is connected to the first rod 100. In detail, the first rod 100 comprises a first connecting end 110 and a first free end 120, and the second rod 200 comprises a second connecting end 210 and a second free end 220. The second rod 200 is connected to the outside of the first connecting end 110 of the first rod 100 through the second connecting end 210. The first connecting end 110 to the first free end 120 of the first rod 100 is a through hollow structure, and the first free end 120 has a built-in first knot tightening portion 121.

[0045] The utility model provides a first rod 100 with a penetrating hollow structure to be sleeved on the outside of the cooling water pipe, and provides a sleeve-knotting tightening portion 121 corresponding to the cooling water pipe. The cooling water pipe is tightened by the first rod 100 to avoid the cooling water pipe from breaking and falling off due to direct action on the through-rod portion of the cooling water pipe.

[0046] The second rod 200 is connected to the outside of the first rod 100 and can be used for tightening the first rod 100. In some embodiments of the utility model, the second connecting end 210 to the second free end 220 of the second rod 200 is also set as a through hollow structure, and the second free end 220 has a built-in second knot tightening portion 221. In this embodiment, the second rod 200 can also be knotted on the outside of the cooling water pipe, and the cooling water pipe is tightened by the second knot tightening portion 221.

[0047] like Figure 3 and Figure 4 As shown, the cooling water pipe 30 includes a threaded opening 31 and a through rod 32, wherein the threaded opening 31 is used for connecting with the connecting structure 40. Figures 1 to 4During the tightening operation, the first free end 120 of the first rod 100 is passed through the through rod portion 32 of the cooling water pipe 30 until the first knotting tightening portion 121 is knotted on the connecting structure outside the threaded mouth portion 31, and the cooling water pipe 30 and the connecting structure 40 are tightened by tightening the first rod 100, wherein the through rod portion 32 of the cooling water pipe 30 can pass through the first connecting end 110 of the first rod 100.

[0048] At this time, the first rod 100 serves as a fixing member for tightening the cooling water pipe 30 , and the second rod 200 serves as an operating member for tightening the first rod 100 .

[0049] In other embodiments, during the tightening operation, the second free end 220 of the second rod 200 is passed through the through-rod portion 32 of the cooling water pipe 30 until the second loop-tightening portion 221 is looped onto the connecting structure outside the threaded mouth 31, and the cooling water pipe 30 and the connecting structure 40 are tightened by tightening the second rod 200, wherein the through-rod portion 32 of the cooling water pipe 30 can pass through the second connecting end 210 of the second rod 200.

[0050] At this time, the second rod 200 serves as a fixing member for tightening the cooling water pipe 30 , and the first rod 100 serves as an operating member for tightening the second rod 200 .

[0051] Preferably, the first rod 100 and the second rod 200 are connected in an L-shape, and the tightening tool for resistance welding cooling water pipes of the utility model is in an L-shape as a whole. The length of the first rod 100 is not equal to the length of the second rod 200, which is suitable for different cooling water pipes 30, so that the first rod 100 or the second rod 200 can be selected to tighten the cooling water pipe 30.

[0052] The first rod 100 has a first inner diameter, the second rod 200 has a second inner diameter, the first inner diameter 100 is equal to the second inner diameter 200, the inner diameters of the first rod 100 and the second rod 200 are the same and correspond to the cooling water pipe 30. In other embodiments, the inner diameters of the first rod 100 and the second rod 200 can be set to be different to accommodate different types of cooling water pipes 30.

[0053] In this embodiment, the connection structure outside the threaded opening 31 of the cooling water pipe 30 is a hexagonal structure, and correspondingly, the first knotted tightening portion 121 of the first free end portion 120 and the second knotted tightening portion 221 of the second free end portion 220 are both configured as inner hexagonal structures of corresponding sizes. However, in other embodiments, the first knotted tightening portion 121 of the first free end portion 120 and the second knotted tightening portion 221 of the second free end portion 220 may also be other fixing structures, or fixing structures of different shapes or sizes, as long as they have the function of fixing the cooling water pipe 30.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first rod 100 has a first outer diameter portion 101 and a second outer diameter portion 102 , the diameter of the second outer diameter portion 102 is larger than the diameter of the first outer diameter portion 101 , wherein the second outer diameter portion 102 is disposed at the first free end portion 120 .

[0055] Similarly, the second rod 200 has a third outer diameter portion 201 and a fourth outer diameter portion 202 , wherein the diameter of the fourth outer diameter portion 202 is greater than the diameter of the third outer diameter portion 201 , wherein the fourth outer diameter portion 202 is disposed at the second free end portion 220 .

[0056] The utility model arranges a slightly larger pipe diameter at the free end portion, which can not only ensure the firmness of the structure of the knot tightening portion in the free end portion, but also facilitates operation as a handle end.

[0057] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
