[0002] When stainless steel pipes are spliced, it is usually necessary to use combined components to match and connect the ends of the steel pipes. For structures that need to be connected together during later use, the connection positions need to be welded. The accuracy of the connection positions is relatively poor, and the stability and bearing capacity during combination are also relatively poor. The matching efficiency during splicing and combination is relatively low, and the connection positions cannot achieve precise isolation and matching. Utility Model Content

For the connection position that requires welding, it can ensure higher accuracy of the connection position, better matching operation during welding, more reliable connection strength, and better durability during later use. By setting up a reinforcement structure inside, it not only improves the overall strength of the inside and outside, but also has the function of isolation and matching, so that the overall service life of the connection position is longer.

[0006] Furthermore, the left end surface of the combined limiting matching plate and the left end surface of the steel pipe main structure are on the same plane.
[0007] Furthermore, a convenient fitting guide structure is provided at the outer edge of the combined connection fitting groove for easy fitting and placement.

[0009] Beneficial effects of the utility model:
[0010] The utility model provides a matching structure at the end of the steel pipe when combined, which not only improves the strength of the connection position, but also can provide accurate combined connection during splicing. For the connection position that requires welding, it can ensure higher accuracy of the connection position, better matching operation during welding, more reliable connection strength, and better durability during later use. By setting up a reinforcement structure inside, not only the overall strength of the inside and outside is improved, but also it has the effect of isolation and matching, which makes the overall service life of the connection position longer.

[0019] like Figures 1 to 7As shown, a separated combined steel pipe includes a cylindrical steel pipe main structure 1, a central conveying through hole 2 is provided at the center position of the steel pipe main structure 1, and a cylindrical reinforcement stabilization stop seat 3 is provided on the left side of the outer cylindrical surface of the steel pipe main structure 1, which can improve the strength of the connection position during assembly, and at the same time can cooperate with the spliced steel pipes at the connection position for precise and stable splicing. The left end face of the reinforcement stabilization stop seat 3 is connected with an integrally formed and circumferentially evenly distributed combination limit matching plate 4, which can limit the structure of the splicing position and ensure better structural stability during splicing. The combination limit matching plate 4 is connected to the outer cylindrical surface of the steel pipe main structure 1 to ensure higher structural strength at the connection position. The left side of the combination limit matching plate 4 and the outer cylindrical surface of the steel pipe main structure 1 are provided with a combination connection matching groove 5, which is inserted and matched with the spliced steel pipe ends when in use. The interior of the central conveying through hole 2 is provided with a reinforced support connecting plate 7 on the inner side corresponding to the reinforced stable stop seat 3, which ensures higher internal structural strength and can play a role in isolating materials during internal conveying, providing a buffering fit for the conveying speed and reducing the impact force during conveying. The depth of the combined connection fitting groove 5 is less than half the length of the combined limit fitting plate 4, ensuring higher structural strength and more reliable connection stability during fitting. The outer right side of the combined limit fitting plate 4 is provided with a safety arc surface for avoiding positioning, which reduces the space occupied by the right side during use. By providing a combined fitting structure at the end of the steel pipe, it not only improves the strength of the connection position, but also provides a precise combined connection during splicing. For connection positions that require welding, it can ensure higher connection accuracy, better fitting operation during welding, more reliable connection strength, and better durability during later use. The internal reinforcement structure not only improves the overall strength of the inside and outside, but also has the function of isolation and fitting, which prolongs the overall service life of the connection position.
[0020] Preferably, the left end face of the combined limiting matching plate 4 is on the same plane as the left end face of the steel pipe main structure 1, so that the structural strength of the combined limiting matching plate 4 position is higher, the overall flatness of the left position is better, and the structural strength of the matching position can reach the maximum.
[0021] Preferably, the outer edge of the combined connection and fitting groove 5 is provided with a convenient fitting guide structure 6 for convenient fitting and placement, so that the connection and fitting operation during the combination is more convenient and the fitting is smoother.
[0022] Preferably, the fastening guide structure 6 is an installation group fitting chamfer structure, which is more convenient during production and processing.
[0023] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or replacements can be made without departing from the principles described in the present invention. These improvements or replacements should also be regarded as the scope of protection of the present invention.
