Specific implementation manners
[0020] Such as Figures 1 to 7As shown in the figure, a combined easy-to-install high-precision steel pipe includes a cylindrical steel pipe main structure 1. An installation auxiliary fitting seat 2 is provided at the end face of the steel pipe main structure 1, which can be used as an installation auxiliary structure for the connection and fitting of the steel pipe main body during installation and fitting. A clearance fitting safety groove 3 is provided at the upper left position of the installation auxiliary fitting seat 2 to ensure a larger space at the upper end position and make the combined operation more convenient when fitting with the connecting steel pipe. A conical combined guiding groove 4 communicating with the inside of the steel pipe main structure 1 is provided on the left side of the installation auxiliary fitting seat 2, making the combined operation during splicing easier and having the function of guiding the fitting. An arc-shaped welding fitting safety groove 5 is provided at the lower end position of the combined guiding groove 4, which can provide precise fitting for the welding material during welding and ensure higher strength during welding. The steel pipe main structure 1 is located at a position slightly above the middle of the installation auxiliary fitting seat 2 to ensure a larger space at the lower end position during fastening and combination, and the structure at the upper end position occupies less space. A precise combined sliding groove 6 that completely penetrates the whole in the left-right direction is provided at the lower end of the installation auxiliary fitting seat 2, which can be fitted and connected with the guide rail at the steel pipe installation position during use. The width of the upper end position of the precise combined sliding groove 6 is greater than the width of the lower end position, and the fitting position has a reliable anti-disconnection effect. Integral fastening connection holes 7 are provided on the installation auxiliary fitting seat 2, which can fixedly connect the integral installation position, ensure more convenient integral fixed connection operation, and higher fastening fitting strength. A combined connection limit boss 8 is formed between the two sides of the welding fitting safety groove 5 and the clearance fitting safety groove 3, which has the function of position calibration when fitting with the splicing steel pipe and ensures higher accuracy during fitting. By integrating the installation components on the steel pipe structure, it can be combined with the slide rail at the installation position during use. It can not only ensure the combined accuracy during fitting, but also be moved and combined in a sliding manner, making the installation more flexible and labor-saving, with higher combined strength at the fitting position. Through the settings of the welding fitting safety groove and the limit connection boss at the connection position, it can ensure higher fitting strength during welding, more reliable firmness at the connection position, stronger overall durability during use, higher installation efficiency at the connection position, and relatively lower overall combined cost.
[0021] Preferably, the projection of the installation auxiliary fitting seat 2 in the left-right direction is a triangular structure, and the installation auxiliary fitting seat 2 is connected to the steel pipe main structure 1 by welding, so that the overall structural support strength is better and the service life during use is longer.
[0022] Preferably, the cross-section of the upper end position of the precise combined sliding groove 6 is an inverted isosceles trapezoid structure, and the lower end of the precise combined sliding groove 6 is a rectangular structure, with higher connection and combination strength, stronger bearing capacity, and higher safety during moving and fitting when fitting with the slide rail.
[0023] Preferably, the depth of the avoidance and cooperation safety groove 3 is less than or equal to half of the thickness of the installation auxiliary cooperation seat 2, which can ensure better overall strength at the installation and cooperation position and more reliable combination firmness during use.
[0024] Preferably, installation combination convenient chamfer structures are provided at the two side edge positions of the overall fastening connection hole 7, which is more convenient during assembly and combination, has the function of cooperation guidance, and can improve the cooperation efficiency during combination.
[0025] The above is the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements or replacements can still be made, and these improvements or replacements should also be regarded as the protection scope of the present utility model.
