Description

Technical Field

[0001] This utility model relates to the field of welding screw technology, and in particular to a welding screw. Background Technology

[0002] Welded screws are special fasteners that are directly fixed to a metal substrate through welding, achieving a metallurgical bond between the screw and the workpiece. Generally, welded screws do not require pre-drilling, thus avoiding weakening the cross-sectional strength of the material. They are suitable for thin plates or space-constrained scenarios. The joints created by welding have higher tensile and shear strengths than traditional screws.

[0003] Most existing welding screws are designed as a single, integrated unit. During use, the screw head is attached to the board surface and welded in place. However, the weld point of the integrated screw is located on the outer edge of the screw head during the welding process, which makes subsequent grinding and cleaning more difficult. Furthermore, the stress on the weld point is most concentrated when the screw is in use, requiring high welding quality and resulting in a decline in the performance of the welding screw.

[0004] Therefore, to address the problem that the weld points of existing welded screws are located on the outer edge of the screw head during the welding process, making subsequent grinding and cleaning difficult and requiring high welding quality, which leads to a decrease in the performance of the welded screws, a composite welded screw can be designed. Utility Model Content

[0005] To overcome the problem that existing welded screws have weld points located on the outer edge of the screw head during the welding process, which makes subsequent grinding and cleaning difficult and requires high welding quality, thus reducing the performance of the welded screws.

[0025] Please see Figures 4-5 In this embodiment, a placement groove 16 is provided on the inner side of the screw connector 15, and a connecting groove 17 is provided on the outer side of the screw connector 15. A limiting groove 18 is provided on the inner side of the screw body 13 and the screw connector 15.

The mounting table 2 is connected through the placement groove 16, and the support bar 4 is connected through the limiting groove 18, thereby initially installing and positioning the support tube 1 and the screw body 13. The welding and fixing effect is enhanced by the connecting groove 17. A moving block 19 is threadedly connected to the screw body 13. A second threaded groove 20 is provided on the inner side of the moving block 19. A grinding disc 21 is installed on the outside of the screw body 13.

[0026] During installation, firstly, the support tube 1 is connected to the predetermined position through the mounting platform 2 and the welding groove 3, and the welding groove 3 is used in conjunction with the welding rod and welding machine to weld and fix it, thereby improving the overall stability. Next, the mounting platform 2 is connected through the placement groove 16, and the support bar 4 is connected through the limiting groove 18, thereby initially installing and positioning the support tube 1 and the screw body 13. Then, the built-in welding bar 7 is placed through the first connecting port 6, and the first threaded tube 8 is installed through the first threaded groove 5, thereby using the connecting top block 10 and the first threaded tube 8 to support and push out the built-in welding bar 7. Finally, the support tube 1, the first threaded tube 8 and the screw body 13 are welded into a whole through the third connecting port 14 and the built-in welding bar 7 in conjunction with the first connecting port 6 and the second connecting port 9, thereby facilitating subsequent fixing work.

[0027] In use, firstly, the connecting head 11 and connecting tube 12 facilitate subsequent material filling, thereby improving the performance of the screw.

Next, the moving block 19 is moved on the screw body 13 through the second thread groove 20, and the grinding disc 21 is used to improve the continuity of the welding position, facilitating the subsequent installation of external equipment. Finally, the supporting tube 1, screw body 13 and first threaded tube 8 are sealed through the sealing joint 22 and sealing bolt 23 to improve the overall integrity of the screw.

[0028] Through the above steps, the screw is connected to the predetermined position by setting the mounting platform 2 and the welding groove 3. During welding, the welding groove 3 is used to place and weld the welding rod and the plate surface, which improves the integration of the mounting platform 2 and the plate surface, reduces the difficulty of cleaning the welding edge, and improves the overall stability. At the same time, the support tube 1 can be used to install the support first threaded tube 8 and install the built-in welding rod 7. During welding, the built-in welding rod 7 connects the various components of the screw, improves the integrity of the screw, thereby improving the overall welding fixation of the screw and improving the subsequent use stability of the welded screw. This solves the problem that the welding point of the existing welded screw is located on the outer edge of the screw head, which makes subsequent grinding and cleaning difficult and requires high welding quality, resulting in a decline in the performance of the welded screw.
