Abstract

A positioning structure of a frame welding assembly for a metal product, the metal product is a holding plate or a holding basket made of metal mesh and contains: multiple bodies, each of the multiple bodies is folded in a square shape and includes multiple raised faces and multiple slots which are stamped on a peripheral side of each body respectively. Two adjacent of the multiple bodies are connected together, and the two adjacent bodies have multiple recesses and multiple protrusions respectively formed on two connection sides thereof so that the multiple recesses retain with the multiple protrusions individually before welding the two adjacent bodies together.

Claims

1. A welded positioning frame assembly for a metal product, the metal product being a holding plate or a holding basket made of metal mesh and comprising: multiple bodies, each of the multiple bodies being folded in a square shape and including multiple raised faces and multiple slots which are stamped on a peripheral side of each body respectively; wherein two adjacent of the multiple bodies are welded together, and each of the two adjacent bodies has multiple recesses and multiple protrusions respectively formed on two connection sides thereof so that the multiple recesses interconnect with the multiple protrusions; wherein a height of each of the multiple protrusions is more than a depth of each of the multiple recesses so that when the two adjacent bodies are connected together, a slit it defined between the two adjacent bodies and the two adjacent bodies are then welded together so that the multiple protrusions partially melt and fill into the slit.

2. The welded positioning frame assembly as claimed in claim 1, wherein the two adjacent bodies are high-frequency welded together so that the multiple protrusions partially melt and fill into the slit.

3. The welded positioning frame assembly as claimed in claim 1, wherein each body includes at least one peripheral rib and multiple recesses and multiple protrusions formed on the at least one peripheral rib.

4. The welded positioning frame assembly as claimed in claim 1, wherein the multiple recesses and the multiple protrusions are alternatively formed on the multiple raised faces or the multiple slots on peripheral sides of the two adjacent bodies respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) With reference to FIGS. 1-5, a positioning structure of a frame welding assembly according to a first embodiment of the present invention is applied to a holding plate of a metal shelf and comprises a body 10 stamped in a C shape from a metal sheet, the body 10 includes a first peripheral rib 11 formed on a first end thereof, a second peripheral rib 12 formed on a second end of the body 10, multiple slots 13 stamped on each of a peripheral side of the body 10, the first peripheral rib 11, and the second peripheral rib 12 respectively so as to reinforce the positioning structure, wherein the body 10 is folded in a square shape, and the first peripheral rib 11 is welded with a metal mesh 20 made of metal material, thus producing the holding plate.

(10) Before welding multiple bodies 10 with the metal mesh 20 so as to produce the holding plate, two adjacent of the multiple bodies 10 have multiple recesses 15 and multiple protrusions 16 respectively formed on two connection sides of the two adjacent bodies 10 respectively, and the multiple recesses 15 and the multiple protrusions 16 are alternatively formed on multiple raised faces 14 or the multiple slots 13 on peripheral sides of the two adjacent bodies 10 respectively, wherein a height of each of the multiple protrusions 16 is more than a depth of each of the multiple recesses 15 so that when the two adjacent bodies 10 are connected together, the multiple recesses 15 individually retain the multiple protrusions 16, and a slit is defined between the two adjacent bodies 10. Thereafter, the two adjacent bodies 10 are high-frequency welded together so that the multiple protrusions 16 partially melt and fill into the slit, thus obtaining aesthetic welding appearance.

(11) Referring further to FIGS. 6 and 7, a difference of a positioning structure of a frame welding assembly of a second embodiment from that of the first embodiment comprises: multiple notches 17 and multiple projections 18 formed on two first peripheral ribs 11 and two second peripheral ribs 12 of the two adjacent bodies 10 respectively, hence the two first peripheral ribs 11 and the two second peripheral ribs 12 of the two adjacent bodies 10 are retained and are high-frequency welded matingly so as to obtain secure connection and aesthetic welding appearance of the two adjacent bodies 10.

(12) As shown in FIG. 8, a positioning structure of a frame welding assembly according to a third embodiment of the present invention is applied to a holding basket made from multiple metal meshes. The positioning structure comprises a body 30 folded and stamped from a metal sheet, the body 30 includes a peripheral rib 31 formed around a peripheral edge thereof, multiple notches 32 and multiple projections 33 which are formed on two connection ends of the peripheral rib 31 respectively, hence the multiple notches 32 and the multiple projections 33 of the peripheral rib 31 retain together individually. Thereafter, the two connection ends of the peripheral rib 31 are high-frequency welded so as to produce the holding basket at high quality.

(13) Thereby, the two adjacent bodies of the positioning structure are connected together by retaining the multiple notches with the multiple projections respectively and in high-frequency welding manner, thus enhancing welding quality.

(14) Furthermore, when the two adjacent bodies are connected together, the multiple recesses individually retain with the multiple protrusions, and two adjacent bodies are high-frequency welded together so that the multiple protrusions partially melt and fill into the slit, thus obtaining aesthetic welding appearance.

(15) While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
