Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a positioning fixture for welding a flip-up display board, as shown in Figures 1-3. It includes a placement plate 1 and a flip-up display board 2. The flip-up display board 2 also includes a rotating shaft 21 and a display board body 22. A support plate 3 is welded to the top of the placement plate 1. Two first L-shaped blocking plates 4 are welded to the top of the support plate 3. A limiting plate 5 is provided on the left side of each of the two first L-shaped blocking plates 4, forming a groove 6 between the limiting plate 5 and the first L-shaped blocking plate 4. Second L-shaped blocking plates 7 are provided on both the front and rear sides of the support plate 3. Third L-shaped blocking plates 8 are provided on both the front and rear sides of the display board body 22. The two third L-shaped blocking plates 8 are staggered. Only two third L-shaped blocking plates 8 are needed to position the display board body 22, reducing the need for third L-shaped blocking plates. The use of the L-shaped baffles 8 allows for the positioning of the rotating shaft 21 to be welded by placing it in the slot 6 between the first L-shaped baffle 4 and the limiting plate 5, thus positioning the left and right positions of the rotating shaft 21. Two second L-shaped baffles 7 are used to position the front and back positions of the rotating shaft 21. The display plate 22 to be welded is placed between two third L-shaped baffles 8, limiting its front and back positions. The display plate 22 is then slid to fit against the rotating shaft 21, allowing for welding of the rotating shaft 21 and the display plate 22. This method facilitates quick and easy positioning of the rotating shaft 21 and the display plate 22, improving the welding efficiency of the flip display plate 2. Furthermore, the welding process does not require manual support, enhancing welding safety.
