In actual construction, there are problems such as inaccurate welding positioning of the mechanical connection sleeve of the steel bar and the steel column, and the angle does not meet the requirements.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example: Reference Figure 1-4A steel bar connection sleeve welding bracket shown in the figure comprises a fixing plate 1, two clamping plates 2 arranged opposite to each other are fixed at the front end of the fixing plate 1, the two clamping plates 2 are detachably connected via a plug-in column 3, and a clamping space for clamping the steel bar connection sleeve is formed between the two clamping plates 2;
[0025] An adsorption ring 4 is fixedly connected to the rear side of the fixed plate 1 through a support rod 5. The inner diameter of the adsorption ring 4 is larger than the outer diameter of the steel bar connecting sleeve. One end of the adsorption ring 4 is adsorbed on the steel column. A limiting loop 100 is formed on the side of the adsorption ring 4 away from the steel column. The limiting loop 100 is ring-shaped and is used to guide the welding tool for ring welding.
[0026] Based on the above structure, by enlarging the inner diameter of the adsorption ring 4 to make it larger than the diameter of the steel bar connecting sleeve, a larger gap is formed between the steel bar connecting sleeve and the adsorption ring 4, reducing the obstruction of the welding point and facilitating the subsequent welding operation. The formed limiting ring 100 can help guide the welding tool, so that the welding tool can move in a circle on the premise of fitting the limiting ring 100, and perform stable circular welding, thereby ensuring good and stable welding quality and improving the welding qualification rate.
[0027] Furthermore, a limiting ring 6 is fixed at the rear side of the fixed plate 1 , the inner diameter of the limiting ring 6 is consistent with the inner diameter of the adsorption ring 4 , a limiting ring channel 100 is formed between the limiting ring 6 and the adsorption ring 4 , and a guide is installed between the limiting ring 6 and the adsorption ring 4 .
[0028] A limiting ring 100 is formed through the gap between the limiting ring 6 and the adsorption ring 4, so that the limiting ring 100 can be used to guide the welding tool, thereby achieving the purpose of stable welding. At the same time, the guide piece pinched by the limiting ring 6 can also play a guiding role for the welding tool, achieving a better welding effect.
[0029] Furthermore, the guide member includes a guide slider 7, both ends of which are slidably connected to the ends of the adsorption ring 4 and the limiting ring 6 that are close to each other. The guide slider 7 moves in a circular motion along the limiting ring 100, and a welding hole 71 is provided on the guide slider 7 for the tip of the welding tool to pass through.
[0030] When welding is required, the staff only needs to pass the welding head of the welding tool through the welding hole 71, and the welding hole 71 guides the welding head of the welding tool to the connection between the steel bar connecting sleeve and the steel column. At this time, the staff only needs to start the welding tool and push the welding tool to move, so that the guide slider 7 can make a circular motion along the limiting ring 100, so as to guide the welding tool to move in a more stable circular manner, which can further improve the stability during welding and further improve the welding quality after welding;
[0031] It should be noted that when the welding tool passes through the support rod 5, it is only necessary to take out the welding tool from one side and reinsert it into the welding hole 71 from the other side to continue welding. Since the width of the support rod 5 is small and the inner diameter of the adsorption ring 4 is large, the support rod 5 will not block the welding tool and cause a welding blind area, so it will not affect the welding operation.
[0032] Furthermore, a slide groove 8 is provided on the end surfaces of the adsorption ring 4 and the limiting ring 6 which are close to each other, and both sides of the guide slider 7 are slidably connected in the slide groove 8 through sliding members 9 .
[0033] Furthermore, one end of the adsorption ring 4 for adsorbing the steel column is set to a plane or arc that fits the steel column, and the limiting ring 100 is set to the same plane or arc as one end of the adsorption ring 4 for adsorbing the steel column, so as to fit steel columns of different shapes, such as round or square, thereby improving the practicality of the steel bar connecting sleeve welding bracket.
[0034] Furthermore, the sliding member 9 includes a sleeve 91, a movable rod 92 and a spring 93. The sleeve 91 is fixed to one side of the guide slider 7, the movable rod 92 is movably inserted in the sleeve 91, and both ends of the spring 93 are respectively pressed against the side wall of the guide slider 7 and one end of the movable rod 92.
[0035] When the limiting ring 100 is set to the same arc shape as one end of the steel column adsorbed by the adsorption ring 4, during the movement of the guide slider 7, the end of the movable rod 92 will produce a certain lateral movement as the bending change of the slide groove 8 occurs, thereby causing the spring 93 to contract or extend, thereby being able to provide stable compensatory support for the movement of the guide slider 7 during its sliding along the limiting ring 100, so that the guide slider 7 can also move smoothly in the arc-shaped limiting ring 100, thereby playing a stable guiding role.
[0036] Furthermore, a ball head 94 is formed at one end of the movable rod 92 away from the guide slider 7, and the ball head 94 is in rolling contact with the inner wall of the slide groove 8. Through the setting of the ball head 94, the contact area between the movable rod 92 and the inner wall of the slide groove 8 can be reduced, thereby reducing the wear of the slide groove 8 and the movable rod 92, and at the same time meeting the requirement of stable contact between the movable rod 92 and the inner wall of the slide groove 8.
[0037] Working principle of the utility model: in daily use, firstly, the steel bar connection sleeve welding bracket is adsorbed on the steel column through the adsorption ring 4, and the steel bar connection sleeve is installed on one side of the steel column through two clamping plates 2 to achieve positioning support, and the inner diameter of the adsorption ring 4 is enlarged to make it larger than the diameter of the steel bar connection sleeve, thereby forming a larger gap between the steel bar connection sleeve and the adsorption ring 4, reducing the obstruction of the welding point and facilitating the subsequent welding operation, and a limiting ring 100 is formed through the gap between the limiting ring 6 and the adsorption ring 4, which can facilitate the welding. The tool is used for guidance. When welding is required, the staff only needs to pass the welding head position of the welding tool through the welding hole 71. The welding hole 71 guides the welding head position of the welding tool to the connection between the steel bar connecting sleeve and the steel column. At this time, the staff only needs to start the welding tool and push the welding tool to move, so that the guide slider 7 can make a circular motion along the limiting ring 100, so as to guide the welding tool to move in a more stable circular manner, which can further improve the stability during welding, further improve the welding quality after welding, and perform stable circular welding, thereby ensuring good and stable welding quality and improving the welding qualification rate.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
