[0002] Bolt ball grid engineering is a common building structure engineering, usually used in stadiums, parks, schools, sports stadiums, exhibition centers, conference halls, large commercial complexes and other places. The cone head is an accessory used in the bolt ball steel grid structure. It is a conical object welded to the end of the steel pipe. The screw of the high-strength bolt passes through the bottom round hole and is screwed into the bolt ball. The nut is inside the cone head to avoid collision between steel pipes on the same bolt ball. The cone head should be made of the same material as the steel pipe.

[0003] When the cone head is welded and fixed to the steel pipe, the cone head and the steel pipe need to be relatively still. However, since there is no limiting structure between the existing cone head and the steel pipe, after the cone head and the steel pipe are aligned, they need to be manually supported and fixed during the welding process, which increases the difficulty of operation when assembling the cone head.

The bottom surface of the cone head body 1 is welded and fixed to the top surface of the connecting steel pipe 4.

[0023] Specifically, when it is necessary to fix the cone head body 1 and the bolt screw 2, the bolt screw 2 is inserted through the top of the cone head body 1, and the bolt head 3 is aligned and sleeved on the positioning protrusion 5, the cone head body 1 is rotated, and the bolt ball is fixed when the cone head body 1 is twisted. After fixation, the connecting steel pipe 4 is aligned with the cone head body 1, so that the limiting protrusion 8 is aligned and inserted into the positioning sleeve plate 7, and the positioning sleeve plate 7 and the positioning inner plate 6 are welded and fixed, and the bottom of the cone head body 1 can be fixed to the connecting steel pipe 4.

[0024] As an optimization solution, Figure 3 and Figure 4As shown, a fixed support plate 10 is symmetrically fixed to the inner wall of the positioning inner plate 6, and an insert block 12 is fixed at the bottom. A fixed sleeve plate 11 is slidably sleeved on the insert block 12, and the outer side of the fixed sleeve plate 11 is fixed to the inner wall of the connecting steel pipe 4. A movable plate 13 is symmetrically slidably arranged inside each insert block 12. A fixed slide rod 16 is slidably sleeved inside each group of two movable plates 13 and a limit block 14. The lower fixed slide rod 16 is set to a horizontally placed "T" shape, and its side wall is fixed on the inner wall of the insert block 12. Both ends of the upper fixed slide rod 16 penetrate the movable plate 13 and are fixed on the inner wall of the insert block 12.

[0025] Specifically, when the cone head body 1 and the connecting steel pipe 4 are aligned and fitted, the insert block 12 is inserted into the fixed sleeve 11, so that the inner wall of the fixed sleeve 11 squeezes the limit block 14, so that the limit block 14 drives the movable plate 13 to compress the spring 15 and move into the insert block 12. When the limit block 14 moves over the fixed sleeve 11, the squeezing of the limit block 14 by the fixed sleeve 11 is released. At this time, the limit block 14 moves to the lower part of the fixed sleeve 11 under the push of the spring 15, and the fixed sleeve 11 can be limited by the limit block 14, so that the cone head body 1 and the connecting steel pipe 4 can be fixed.
