[0003] During the welding process of traditional reverse-hanging hinges on the market, operators need to manually position the hinges and shaft cylinder. This process is not only time-consuming and labor-intensive, but also difficult to ensure welding accuracy and repeatability. Moreover, before the availability of this positioning tool, welding of reverse-hanging hinges was entirely based on feel. Improper welding can easily make it difficult to open the compartment panel, resulting in the need for subsequent rework and other unnecessary processes.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] See also Figures 1 to 3 , the utility model provides a technical solution:
[0034] A reverse-hanging hinge welding positioning tool comprises an outer square steel tube 1 and an inner square steel tube 2. The inner square steel tube 2 is located behind the outer steel tube 1. A reverse-hanging hinge 3 is rotatably installed between the upper end surfaces of the outer steel tube 1 and the inner square steel tube 2. The upper end surface of the inner square steel tube 2 is provided with a positioning component 4. The positioning component 4 is generally U-shaped. The positioning component 4 comprises a positioning plate 41 fitted on the upper end surface of the inner square steel tube 2. An inner positioning block 42 is fixedly installed at the center position of the inner rear side wall of the positioning plate 41. Side positioning blocks 43 are fixedly installed on both side walls of the inner opening of the positioning plate 41. A picking piece 44 is fixedly installed at the center position of the upper rear end of the positioning plate 41. The reverse-hanging hinge 3 comprises an inner page 32 rotatably installed inside the positioning plate 41.
[0035] The front end of the inner page 32 is fixedly mounted with an inner sleeve 33 . The reverse hanging hinge 3 further comprises an outer page 31 located on the upper end surface of the outer square steel tube 1 . The front end of the inner sleeve 33 is slidably mounted on the inner side of the rear end of the outer page 31 .
[0036] A latch 34 is installed inside the outer page 31 and the inner sleeve 33 from the left end to the right end. The diameter of the left end of the latch 34 is larger than the outer diameter of the outer page 31. A limit ring 35 is slidably installed on the outer circumferential surface of the right end of the latch 34. A through hole is provided on the right end circumferential surface of the latch 34. A limit rod 36 is slidably installed in the through hole on the right end circumferential surface of the latch 34 located on the outside of the limit ring 35; the upper plate 5 is fixedly installed on the rear end of the lower part of the positioning plate 41, and through openings 51 are provided at the left and right corners of the upper part of the upper plate 5. A sliding groove 46 is provided inside the positioning plate 41 near the edges of both sides from the front end to the rear end, and the front end of the through opening 51 is connected to the rear end of the sliding groove 46.
[0037] By adopting the above technical solution, when in use, the positioning plate 41 in the positioning assembly 4 is placed on the upper surface of the inner square steel tube 2. At this time, the operator allows the positioning rod 47 to slide, so that the front end of the positioning plate 41 can slide to the upper surface of the outer square steel tube 1. At this time, under the action of the positioning rod 47, the upper surfaces of the outer square steel tube 1 and the inner square steel tube 2 are in a parallel state.
[0038] Then, the operator places the outer leaf 31 at the front end of the reverse hanging hinge 3 on the upper surface of the outer square steel pipe 1 , and then rotates the inner leaf 32 so that the inner leaf 32 can be rotated to the inside of the positioning plate 41 .
[0039] At this time, under the restriction of the positioning plate 41, the position of the reverse hanging hinge 3 is generally restricted. At this time, after the inner page 32 rotates to the inside of the positioning plate 41, the inner page 32 is mainly positioned in all directions under the action of the inner positioning block 42 and the side positioning block 43, so that the inner page 32 is positioned.
[0040] Finally, the reverse hinge 3 is welded to the upper surface of the outer steel pipe 1 and the inner steel pipe 2 by manual welding by the operator, and the reverse hinge 3 will not be offset; and the latch 34 of the reverse hinge 3 is ensured to be parallel to the outer steel pipe 1 and the inner steel pipe 2, thereby ensuring the smooth opening and closing of the subsequent box panels.
[0041] Specifically, such as Figures 4 and 5 As shown, a common positioning rod 47 is slidably installed inside the two through-holes 51 opened at the corner positions of the upper plate 5, and both sides of the front end opening of the positioning rod 47 are slidably installed inside the slide groove 46; a lower plate 6 is provided below the upper plate 5, and an insert plate 7 is provided between the upper plate 5 and the lower plate 6, and both ends of the insert plate 7 are slidably installed inside the adjacent upper plate 5 and lower plate 6.
[0042] A horizontal plate 8 is fixedly installed on the lower front end surface of the lower plate 6, and an outer plate 9 is provided at the front end of the horizontal plate 8. A first slide plate 10 is slidably installed inside the front end surface of the horizontal plate 8, and a second slide plate 11 is slidably installed inside the rear end surface of the outer plate 9; a plurality of folding rods 12 are provided between the first slide plate 10 and the second slide plate 11, and the plurality of folding rods 12 are rotatably connected by hinges, and the two folding rods 12 at the front and rear ends are rotatably connected to the adjacent first slide plate 10 and the second slide plate 11 by hinges.
[0043] By adopting the above technical solution, when in use, the lower plate 6 is allowed to slide downward, so that the horizontal plate 8 and the outer plate 9 can be adapted to the outer square steel tube 1 and the inner square steel tube 2 of different thicknesses. It should be noted that under the action of the inserting plate 7, the upper plate 5 and the lower plate 6 are in a connected state, and the lower plate 6 will only slide up and down when manually pulled. In the absence of external force, the lower plate 6 will not move at all, thereby ensuring the stability of the structure.
[0044] Secondly, the outer plate 9 is pulled away from the horizontal plate 8 by the operator. At this time, under the action of the second slide plate 11, the outer plate 9 can be kept in a horizontal state, thereby supporting the lower end surface of the outer steel pipe 1.
[0045] Then, in order to cope with the outer square steel tube 1 and the inner square steel tube 2 of different thicknesses, the folding rod 12 can be pulled out under the action of the second slide 11. The folding rod 12 is multiple and is rotated with a damping hinge. At this time, the operator manually rotates the folding rod 12 so that the folding rod 12 and the first slide 10 are in a 90-degree structural state, and the second slide 11 is also in a 90-degree state with the first slide 10 under the action of the folding rod 12. At this time, under the action of the folding rod 12, the second slide 11 is rotated so that the second slide 11 and the first slide 10 are in a 90-degree state. The first slide plate 10 is also in a parallel state, so that the second slide plate 11 can support and limit the lower end surface of the outer steel tube 1 whose thickness exceeds that of the inner square steel tube 2; with the cooperation of the above-mentioned multiple structures, the upper end surfaces of the outer steel tube 1 and the inner square steel tube 2 can be in a flush state, and then the lower end surfaces of the outer steel tube 1 and the inner square steel tube 2 can be supported with the cooperation of multiple structures such as the horizontal plate 8, the outer plate 9 and the folding rod 12, so as to further ensure that the outer steel tube 1 and the inner square steel tube 2 will not be misaligned.
[0046] Working principle: First, place the positioning plate 41 at the position where welding is required. The operator rotates the inner page 32 so that the inner page 32 rotates to the inside of the positioning plate 41, and under the action of the inner positioning block 42 and the side positioning block 43, the inner page 32 is fixed.
[0047] After the inner page 32 is fixed, the operator welds the inner page 32 and the outer page 31, so that the pin 34 of the reverse hinge 3 can be parallel to the outer steel pipe 1 and the inner steel pipe 2, thereby ensuring the opening and closing of the box panel.
[0048] Secondly, under the action of the positioning rod 47, the upper end surfaces of the outer square steel tube 1 and the inner square steel tube 2 can be ensured to be in a horizontal state.
[0049] Finally, under the action of multiple structures such as the horizontal plate 8 and the outer plate 9, the lower end surfaces of the outer steel tube 1 and the inner steel tube 2 can be supported and restricted, further enhancing the stability of the welding of the reverse hanging hinge 3.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
