[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3As shown, this utility model provides a technical solution: a quick-connectable steel pipe, including a steel pipe 1, a rotatable annular rotating plate 2 on the outer surface of the steel pipe 1, a fixed rack 3 fixedly installed on the outer surface of the annular rotating plate 2, an annular grip handle 4 fixedly installed on the outer surface of the annular rotating plate 2, and a connecting and fixing device 5 in the middle of the steel pipe 1. The annular grip handle 4 facilitates the operator to apply force, drive the annular rotating plate 2 to rotate, thereby enabling the fixed rack 3 to function and providing a power transmission path for the quick connection of the steel pipe.

[0020] The connecting and fixing device 5 includes a fixed bracket 501 fixedly installed on the outer surface of the steel pipe 1 on the right side. A slidable tensioning crossbar 502 is provided on the top of the fixed bracket 501. A tensioning bracket 503 connected to the steel pipe 1 on the left side is provided on the left side of the tensioning crossbar 502. A rotatable bending pull rod 504 is provided in the middle of the tensioning crossbar 502. A movable upright block 505 is fixedly installed on the right side of the bending pull rod 504. An installation bracket 506 is fixedly installed on the outer surface of the steel pipe 1 on the right side. A rotating screw 507 threaded inside the installation bracket 506 is provided on the top of the installation bracket 506. A rotating gear 508 is fixedly installed on the right end of the rotating screw 507. The fixed rack 3 meshes with the rotating gear 508. This structural design, through the coordinated cooperation of various components, converts the rotation of the annular rotating plate 2 into the linear movement of the tensioning crossbar 502, thereby realizing the rapid connection of the steel pipe.

[0021] Specifically, such as Figure 1 and Figure 2 As shown, an annular slider is fixedly installed on the inner side of the annular rotating plate 2, and an annular groove is opened on the outer surface of the steel pipe 1 on the right side. The annular slider is rotatably connected to the annular groove. This structure allows the annular rotating plate 2 to rotate flexibly on the outer surface of the steel pipe 1, while ensuring the stability and smoothness of the rotation process. There are two sets of steel pipes 1, and the inner side of both sets of steel pipes 1 is provided with sealing rubber strips. The sealing rubber strips can effectively prevent leakage during fluid transportation and improve the sealing performance after the steel pipes are connected. It is suitable for engineering scenarios with requirements for sealing performance.

[0022] Specifically, such as Figure 3 As shown, a fixing groove is provided on the left side of the tensioning crossbar 502. The fixing groove is inserted into the interior of the tensioning bracket 503. The design of the fixing groove makes the tensioning crossbar 502 and the tensioning bracket 503 more stable during the initial fixing, and can better transmit the tension during the subsequent tensioning process, ensuring the reliability of the connection. A long strip-shaped through hole is provided at the top of the tensioning crossbar 502. The fixing bracket 501 slides inside the long strip-shaped through hole. The long strip-shaped through hole provides guidance and space for the sliding of the tensioning crossbar 502, ensuring that it will not deviate during the movement and ensuring the accuracy of the connection operation.

[0023] The working principle of this utility model is as follows:

[0024] S1. When it is necessary to connect the steel pipes 1, insert the tensioning crossbar 502 into the tensioning bracket 503 to perform simple preliminary fixation on the two sets of steel pipes 1.

[0025] S2. Then, control the ring grip handle 4 to drive the ring rotating plate 2 to rotate. The ring rotating plate 2 drives the fixed rack 3 to mesh with the rotating gear 508. The rotating gear 508 drives the rotating screw 507 to rotate. The rotating screw 507 drives the moving block 505 to move. The moving block 505 drives the bending pull rod 504 to move. The bending pull rod 504 drives the tensioning column 502 to move to the right. The tensioning column 502 pulls the tensioning bracket 503 to achieve quick connection and fixation of the two sets of steel pipes 1.

[0026] In summary, this quick-connect steel pipe, through the setting of annular grip handle 4, drives annular rotating plate 2 and fixed rack 3 to mesh with rotating gear 508, so that rotating screw 507 drives moving block 505 and bending pull rod 504 to drive tension crossbar 502 to engage with tension bracket 503, realizing the quick connection operation of steel pipe 1. This makes the connection of steel pipe 1 more time-saving and labor-saving, and can be completed quickly without professional personnel using professional tools. It has a more efficient connection efficiency for steel pipe 1, which helps people use it better and effectively improves the convenience of use.
