[0032] The hinged positioning structure 200 can be arranged on the first side of the tool main body 100, and can be used to position a plurality of first ear plates 1, wherein the first ear plates 1 are used to hinge the explosion-proof valve support plate 2, and the explosion-proof valve support plate 2 can include a locking structure 4 used to lock the explosion-proof valve support plate 2 after opening the explosion-proof valve 3 connected to the explosion-proof valve support plate 2; the locking positioning structure 300 can be arranged on the first side of the tool main body 100, and can be used to position at least one second ear plate 5, wherein the second ear plate 5 is used to cooperate with the locking structure 4 for locking.

[0033] In an embodiment, the hinged positioning structure 200 can be arranged on the first side of the tool main body 100 by welding, one-piece molding, etc., which is not limited here.

[0034] In an embodiment, the hinged positioning structure 200 can include a plurality of positioning sockets arranged on the first side of the tool main body 100, and the plurality of positioning sockets correspond one-to-one to the plurality of first ear plates 1. The first ear plates 1 can be limited by the positioning sockets to achieve positioning.

[0035] In an embodiment, the first ear plate 1 is provided with a through hole, and the hinged positioning structure 200 can be provided with a plurality of hollow positioning barrels of the positioning sockets. The length of the hollow positioning barrel is the same as the length of the first side of the tool main body 100, and the inner diameter of the hollow positioning barrel is the same as the inner diameter of the through hole of the first ear plate 1. The first ear plate 1 can be first limited by the positioning socket of the hollow positioning barrel to align and coincide the columnar core of the hollow positioning barrel with the columnar core of the through hole, and then the first positioning column with the same outer diameter as the inner diameter of the hollow positioning barrel is arranged through the hollow positioning barrel and the through hole of the first ear plate 1, thereby achieving positioning of the first ear plate 1.

[0036] In an embodiment, the hinged positioning structure 200 includes a plurality of positioning portions 210, at least one positioning portion 210 is arranged at the first end of the first side of the tool main body 100, and at least one positioning portion 210 is arranged at the second end of the first side of the tool main body 100. The positioning portion 210 is used to position one of the plurality of first ear plates 1; the locking positioning structure 300 is arranged at at least one of the first end of the first side of the tool main body 100 and the second end of the first side of the tool main body 100. When the locking positioning structure 300 is a plurality, each locking positioning structure 300 can be arranged at at least one of the first end of the first side of the tool main body 100 and the second end of the first side of the tool main body 100. The specific arrangement can refer to the arrangement of the locking structure 4 on the explosion-proof valve support plate 2 corresponding to the tool, which is not limited here.

[0037] In an embodiment, the positioning portion 210 can be one or more of a hollow positioning barrel, a positioning sheet with a through hole having the same inner diameter as the through hole of the first ear plate 1, etc., which is not limited here.

[0038] In an embodiment, the positioning part 210 can be a positioning assembly provided with a second positioning column extending outwardly, and a first lug plate 1 can be sleeved onto the second positioning column on the corresponding positioning part 210 through the through hole of the first lug plate 1, so as to realize the positioning of the first lug plate 1. Since the positioning part 210 is provided with the second positioning column, compared with the through hole provided on the other positioning part 210, the time for simultaneously sleeving the through hole of the positioning part 210 and the through hole of the first lug plate 1 through one column can be saved, so that the alignment can be more convenient and simple.

[0039] In an embodiment, each positioning part 210 extends away from the tool body 100 on the first side of the tool body 100. The extension distance is various and is not limited here. As shown in FIG. 1, by extending the positioning part 210, the lug plate welding tool can reduce the part of the tool body 100 between the positioning parts 210, so that the lug plate welding tool can be more portable.

[0040] In an embodiment, the locking positioning structure 300 extends away from the positioning part 210 on one of the plurality of positioning parts 210. Specifically, the locking positioning structure 300 can extend outwardly on the positioning part 210 in the same direction away from the tool body 100 of the positioning part 210. By extending the locking positioning structure 300 away from the positioning part 210 on the positioning part 210, when positioning the second lug plate 5, the tool does not need to be turned up to position the second lug plate 5, so that the positioning method of the second lug plate 5 is more convenient and simple, thereby improving the positioning efficiency of the lug plate.

[0041] In an embodiment, the positioning part 210 forms an extension structure 220 on the first side of the tool body 100; and the locking positioning structure 300 is arranged on at least one of the plurality of extension structures 220. Specifically, when positioning the second lug plate 5, the tool needs to be turned up, and the turning-up angle depends on the specific height of the second lug plate 5.

[0042] In an embodiment, the hinge positioning structure 200 can further comprise a plurality of first pads 230 corresponding to the plurality of positioning portions 210, and the first pads 230 are arranged on the side of the corresponding positioning portions 210 in contact with the positioned first ear plate 1. By arranging the first pads 230, when the first ear plate 1 is positioned with the corresponding positioning portion 210, the first ear plate 1 can not be in direct contact with the material of the positioning portion 210, thereby reducing the wear of the first ear plate 1 by the positioning portion 210; and after the first ear plate 1 is tightly fixed with the corresponding positioning portion 210 to complete the positioning, the first pad 230 can reduce the rotation of the first ear plate 1 relative to the positioning portion 210, thereby improving the positioning accuracy.

[0043] In an embodiment, the locking positioning structure 300 comprises at least one second pad 310 arranged on the side of the locking positioning structure 300 in contact with the positioned second ear plate 5. By arranging the second pad 310, when the second ear plate 5 is positioned with the locking positioning structure 300, the second ear plate 5 can not be in direct contact with the material of the locking positioning structure 300, thereby reducing the wear of the first ear plate 1 by the locking positioning structure 300; and after the second ear plate 5 is tightly fixed with the locking positioning structure 300 to complete the positioning, the second pad 310 can reduce the rotation of the second ear plate 5 relative to the locking positioning structure 300, thereby improving the positioning accuracy.

[0044] In an embodiment, the tool body 100 can comprise a plurality of positioning holes 110, and the distribution positions of the plurality of positioning holes 110 on the tool body 100 are the same as the distribution positions of the plurality of fixing columns 7 on the mounting flange 6 of the explosion-proof valve 3.
