Description

Technical Field

[0001] The utility model relates to the technical field of welded pipes, in particular to a welded pipe for a medical bed with good bending resistance. Background Art

[0002] During the production of medical beds, welded pipes are connected to other pipes through precise welding processes such as argon arc welding and laser welding to form the main structure of the bed. However, most commonly used welded pipes are hollow. Over the long-term use of a medical bed, the performance of the welded pipes gradually deteriorates due to metal fatigue, and the pipes are likely to bend. This bending can cause changes in the support structure of the medical bed, reducing support strength, and ultimately causing deformation of the bed, affecting its use. Utility Model Content

[0003] The purpose of the utility model is to provide a welded pipe for a medical bed with good bending resistance, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a welded pipe for a medical bed with good bending resistance, comprising a square pipe, wherein anti-wear strips are installed at the four corners of the square pipe. The anti-wear strips are L-shaped and have grooves on the surface. The anti-wear strips can prevent the reinforcing strips from directly contacting the square pipe, thereby reducing wear and increasing the contact area between the reinforcing strips and the square pipe, thereby providing more sufficient support and preventing the square pipe from deforming easily.

[0005] The assembly column is inserted into the center of the square tube. Four reinforcement strips are connected to the surface of the assembly column. The reinforcement strips are connected to the corresponding anti-wear strips through grooves. The four reinforcement strips and the square tube form a triangular support structure, making the square tube structure more stable.

[0006] The support tubes are provided with four pieces and have a flat surface on the surface of the support tubes. The flat surface fits the inner wall of the square tube. The support tubes are connected to the assembly column, which can further improve the bending resistance of the square tube.

[0007] Furthermore, a sealing cover is sleeved on the end of the square tube, and a plurality of assembly holes are provided on the surface of the square tube. Fixing wires screwed to the assembly holes are inserted into the surface of the sealing cover. The sealing cover shields the square tube to prevent debris from entering the interior of the square tube and also improves the sense of integrity of the square tube.

[0008] Furthermore, a transfer strip is provided on the surface of the support tube, a plug-in groove is provided on the surface of the assembly column, and the reinforcement strip and the transfer strip are connected inside the plug-in groove, so as to facilitate the splicing of the assembly column, the reinforcement strip and the transfer strip.

[0009] Furthermore, a plurality of receiving grooves are provided on the surface of the anti-wear strip, and glue can be applied to the receiving grooves to improve the strength of the connection between the anti-wear strip and the square tube.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: four reinforcing strips cooperate with the assembly columns to support the four corners of the square tube inside the square tube, ensuring that the corners of the square tube are not easy to bend; the four supporting tubes support the four sides of the square tube, thereby improving the compressive resistance of the four sides of the square tube, ensuring that the square tube is not prone to metal fatigue problems during long-term use; the medical bed welded with the square tube has high structural strength, will not deform during long-term use, and has better quality.
