Description

Technical Field

[0001] This utility model relates to the technical field of metal welding, and in particular to a sloped welding structure. Background Technology

[0002] Metal welding is a common method of metal connection. After welding, metals can be fixed. Common welding angles are vertical welding and planar welding. When two objects are in contact and form an angle, the solder will weld at the angle between the two objects. After the solder melts, it is not easy to enter the gap between the two objects. At the same time, the weld between the two objects will form a slope, which will reduce the compressive strength of the weld edge and affect the aesthetics and structural strength of the weld between the two objects. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sloped welding structure to solve the problem of the impact of welding on the aesthetics and structural strength of metal parts.

[0004] Based on the technical problems existing in the background art, this utility model proposes a slope welding structure, including two interconnected first workpieces and second workpieces. The first workpiece has an embedded hole on its upper part and an annular stepped groove along the embedded hole. The second workpiece has a corresponding plug body for insertion into the embedded hole on its lower part. When the plug body is inserted into the embedded hole, the stepped groove is filled with solder to connect the first workpiece and the second workpiece.

[0005] Preferably, the bottom surface of the ladder groove is lower than the upper surface of the first workpiece, and the ladder groove and the side surface of the connector form a U-shaped groove.

[0006] Preferably, the apex angle where the ladder groove contacts the second workpiece is a guide slope.

[0007] Preferably, the solder fills the U-shaped groove to connect the stepped groove with the connector of the second workpiece, and the upper surface of the solder is lower than the upper surface of the first workpiece.

[0008] Compared with the prior art, the slope welding structure proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0009] This invention can increase the aesthetics of welding between two workpieces, while the welded body can avoid protruding from the surfaces of the two workpieces, improving the flatness between the workpieces. The solder in this invention can increase the connection area and connection strength between the two workpieces, thereby improving the structural strength. Attached Figure Description

[0014] Example

[0015] Please refer to Figures 1 to 3 This utility model proposes a sloped welding structure, including two interconnected first workpieces 1 and second workpieces 2. The first workpiece 1 has an embedded hole 11 at its top, and an annular stepped groove 12 along the embedded hole 11. The second workpiece 2 has a corresponding insert body 21 below the embedded hole 11. When the insert body 21 is inserted into the embedded hole 11, the stepped groove 12 is filled with solder 4 to connect the first workpiece 1 and the second workpiece 2. In this design, the first workpiece 1 is a tubular workpiece or a workpiece with a thickness greater than the depth of the stepped groove 12. During installation, the insert body 21 of the second workpiece 2 is inserted into the embedded hole 11, leaving a small gap between the insert body 21 and the embedded hole 11. Solder 4 is placed in the stepped groove 12 for welding, connecting the stepped groove 12 to the side of the second workpiece 2. After melting, the solder 4 remains within the stepped groove 12, and some of the molten solder 4 flows through the gap to strengthen the weld between the first workpiece 1 and the second workpiece 2, preventing the welded body from protruding from the surfaces of the first workpiece 1 and the second workpiece 2.

[0016] In specific implementation, refer to Figure 3 The bottom surface of the stepped groove 12 is lower than the upper surface of the first workpiece 1, and the stepped groove 12 and the side of the plug body 21 form a U-shaped groove 3. In this solution, the U-shaped groove 3 can provide a short-term storage space for the melting of the solder 4, provide a re-molding space for the molten solder 4, and provide a connection space for the first workpiece 1 and the second workpiece 2.

[0017] In specific implementation, refer to Figure 3 The apex of the groove 12 that contacts the second workpiece 2 is the guide slope 13. In this scheme, the guide slope 13 can guide the molten solder 4, fill the gaps mentioned above, and increase the firmness.

[0018] In specific implementation, refer to Figure 3 Solder 4 fills the U-shaped groove 3 to connect the stepped groove 12 with the plug body 21 of the second workpiece 2. The upper surface of solder 4 is lower than the upper surface of the first workpiece 1. In this solution, after the solder 4 melts, it can connect the first workpiece 1 and the second workpiece 2 in the U-shaped groove 3 and increase the connection area between the two. At the same time, it changes the shape of the melted solder 4 and improves the welding strength.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
