Furthermore, the welding positions of the upper spherical shell and the lower spherical shell are provided with corresponding welding grooves, so that better welding is facilitated.
Furthermore, chord member through holes corresponding to the threaded connection chord members are formed in the upper spherical shell and the lower spherical shell, so that the threaded connection chord members can be welded more firmly.
Furthermore, the threaded connection chord member avoids the welding parts of the upper spherical shell and the lower spherical shell, so that the mutual influence among welding seams is reduced, and the welding is firmer.
Furthermore, the cross cylindrical support tube comprises a first support frame welded with the front part and the rear part of the upper spherical shell, a second support frame welded with the left part and the right part of the upper spherical shell, and a third support frame welded with the top of the upper spherical shell and abutted against the lower spherical shell, wherein the first support frame, the second support frame and the third support frame are mutually perpendicular and are welded in a penetrating manner, so that the better support of the hollow ball is realized, and the better strength of the hollow ball is improved.
Compared with the prior art, the utility model, have following advantage:
the utility model discloses simple structure, can be fine support the hollow ball can improve the intensity of clean shot greatly, and support and can also carry out welding position to spherical shell down, and it can more be favorable to the welding to be provided with the groove between spherical shell and the spherical shell down, and the threaded connection chord member of setting can carry out the prewelding, and the on-the-spot welded operation intensity that reduces that can be fine is provided with the chord member moreover and can makes through-hole threaded connection chord member welding easier, also more firm, and the result of use is better.
