Description

Technical Field

[0001] The utility model belongs to the field of metal furniture, in particular to a fixing device for welding metal furniture. Background Art

[0002] Compared to traditional wooden furniture, steel furniture offers significant advantages in fire resistance, durability, and environmental friendliness. Steel furniture is typically constructed from cold-rolled steel sheets, and its surface is electrogalvanized, hot-dip galvanized, electrostatically powder-coated, or phosphated and then sprayed with epoxy resin. This results in high hardness and strong coloration, preventing the paint from peeling or surface dents from common impacts. This ensures that office furniture remains fresh and new throughout frequent use, and the simple, elegant straight-line design ensures that steel office filing cabinets remain timeless, even over extended periods of use. Furthermore, the aforementioned coloring methods avoid the production of harmful gases that are detrimental to health, making their use safer and more environmentally friendly.

[0003] The existing technology has specially developed some fixing devices for furniture welding. For example, the Chinese patent with the announcement number "CN210334924U" announced "A fixing device for welding steel furniture", which is suitable for auxiliary fixation during welding of sheet metal steel furniture. The staff can adjust the angle between the two sets of support arms according to the angle of the welding angle, so that the angle between the two sets of support arms is equal to the welding angle, and then place multiple sets of devices with adjusted angles between the welding plates, so that the magnet blocks on both sides are respectively attracted and fixed to the welded sheet metal, thereby avoiding the need for manual assistance during welding.

[0004] Although the angle between the two sets of support arms is adjusted by the angle of the welding angle, and then multiple sets of angle-adjusted devices are placed between the welding plates, so that the magnet blocks on both sides are respectively attracted and fixed to the welded sheet metal, thereby avoiding the need for manual assistance during welding, but in the above structure, the angle adjustment will be limited by the angle, and only a few angles can be adjusted, which will cause inconvenience to the staff during use. Moreover, when using the above structure, the first support rod and the second support rod cannot be effectively folded up when stored, which will cause inconvenience in storage and will take up most of the space. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a fixing device for welding metal furniture to solve the problem of fixing metal furniture.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The cam is connected to the second support rod by a screw thread on the first support rod and the second support rod by a screw thread on the second support rod, and the cam is connected to the second support rod by a screw thread on the first support rod and the second support rod by a screw thread on the second support rod.

[0008] As a preferred technical solution, a circular groove is provided inside one end of the first support rod and the second support rod close to the bottom block, and the spiral column is accommodated inside the circular groove.

[0009] As an optimal technical solution, the end of the spiral column away from the circular groove is fixedly mounted with a rotating shaft, the bottom block is fixedly mounted on one end of the rotating shaft, and the end of the bottom block away from the rotating shaft is fixedly mounted with an anti-slip pad.

[0010] As a preferred technical solution, a rectangular groove is provided on one side of the first support rod and the second support rod, and a plurality of pin interfaces are provided on both sides of the interior of the rectangular groove.

[0011] As an optimal technical solution, slots are provided on both sides of the interior of the sliding block, a spring is fixedly installed inside the slot, a pin connection block is fixedly installed on one end of the spring away from the spring, and the pin connection block is clamped inside the pin interface.

[0012] As an optimal technical solution, pin holes are opened inside the two groups of the raised blocks, and an installation groove is opened inside one end of the raised block near the first stabilizing rod and the second stabilizing rod, and a screw is slidably connected inside the installation groove, and a nut is threadedly connected to one end of the screw, and the screw is slidably connected to the inside of the installation groove through the pin hole opened inside the raised block.

[0013] As an optimal technical solution, circular blocks are integrally formed on both sides of the end of the fixing plate away from the first stabilizing plate, and a connecting groove is opened inside the end of the mounting plate away from the second stabilizing rod, and the circular blocks are rotatably installed inside the connecting groove.

[0014] In summary, the present invention has the following beneficial effects:

[0015] When a larger support angle is needed, the staff can push the sliding block to the end close to the first support rod and the second support block, so that the opening angle of the first support rod and the second support rod will become larger, which can be effectively applied to more places and improve the portability. When the first support rod and the second support rod are to be folded, the staff can adjust the sliding block to the farthest point, so that the folding effect of the first support rod and the second support rod can be achieved, which is convenient for storage and placement.
