[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0025] like Figure 1-5 As shown, the economizer converter tube guard plate welding assembly of the embodiment includes a first base 1 and a flip base 2 rotatably connected to the first base 1. The first base 1 is provided with a first arc-shaped groove 11 that cooperates with the guard plate 3. The guard plate 3 is disposed in the first arc-shaped groove 11, and the converter tube 5 is disposed on the guard plate 3. The flip base 2 is provided with a second arc-shaped groove 21. The second arc-shaped groove 21 is provided with a fixing component for fixing the position of the connecting arc plate 4. The flip base 2 is provided with two working positions. In the first working position, the flip base 2 is in an open state and is used to place the connecting arc plate 4. In the second working position, the flip base 2 cooperates with the first base 1 to be in a closed state, and the connecting arc plate 4 is in contact with the guard plate 3 for welding.

[0026] With this design, the protective plate is first placed in the first arc-shaped groove of the first base. Since both the conversion tube and the protective plate are curved tubes, the protective plate only needs to be placed in place to achieve its positioning. Then, the conversion tube is placed on the protective plate. The second arc-shaped groove of the flip base is equipped with a fixing component, and the connecting arc plate is fixed in position by the fixing component. Then, the flip base is simply flipped to cooperate with the first base, and the connecting arc plate and the protective plate abut against each other to perform welding, so that the protective plate is fixed to the outer periphery of the conversion tube.

[0027] According to one embodiment of the present invention, the fixing component includes a fixing arc plate 6, which is fixedly connected to the second arc groove 21, and the fixing arc plate 6 is magnetically attracted to the connecting arc plate 4.

[0028] With this design, since the connecting arc plate is made of ferrous material, it can be magnetically attracted, and the fixing arc plate is fixed by magnetic attraction, which is simple and quick.

[0029] According to one embodiment of the present invention, the fixed arc plate 6 is provided with a limiting wall 61 that abuts against the side wall of the connecting arc plate 4.

[0030] This design achieves the goal of limiting the connection between the arc plate and the fixed arc plate in the axial direction.

[0031] According to one embodiment of the present invention, the fixed arc plate 6 is provided with an arc-shaped groove 62 that contacts the connecting arc plate 4.

[0032] This design increases the contact area of ​​the limit switch and improves its stability.

[0033] According to one embodiment of the present invention, the side wall of the flipping base 2 is provided with an operation groove 22 for easy welding, and the operation groove 22 is arranged adjacent to the fixed arc plate 6.

[0034] This design provides the welding area with a clear view and ease of use.

[0035] According to one embodiment of the present invention, a flat plate is further included for making the end face of the connecting arc plate 4 horizontal, the flat plate being movably disposed on one side of the first base 1.

[0036] With this design, the flat plate is movable. After all the connecting arc plates are placed, there will be unevenness at both ends of the connecting arc plates. At this time, the connecting arc plates can be manually adjusted or the flat plate can be placed on the connecting arc plates. Simply adjusting the flat plate to be horizontal will indicate that the two ends of the connecting arc plates are flush.

[0037] According to one embodiment of the present invention, the side wall of the first base 1 is provided with a shaft groove 12, and the side wall of the flip base 2 is provided with a rotating shaft 23 that rotates with the shaft groove 12, and the rotating shaft 23 is offset from the operating groove 22.

[0038] This design achieves the purpose of flipping the base.

[0039] According to one embodiment of the present invention, in the second working state, the inner wall of the connecting arc plate 4 is abutted against the outer wall of the guard plate 3.

[0040] This design increases the welding contact area between the connecting arc plate and the guard plate, thus improving the strength of the weld.

[0041] According to one embodiment of the present invention, in the second working state, the limiting wall 61 is in contact with or in a gap fit with the conversion tube 5.

[0042] This design avoids the influence of the limiting wall on the fit between the connecting arc plate and the guard plate.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
