DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figures 1-9 As shown, the present invention is a stainless steel pipe welding and butt-jointing device, comprising a positioning frame 1, a mounting frame 6 is welded and fixed on the surface of the positioning frame 1, a screw handle 20 is rotatably connected to the surface of the mounting frame 6, a long rod 22 is fixedly connected to the surface of the screw handle 20, a connecting section 25 is sleeved and connected to the surface of the long rod 22, connecting blocks 30 are provided on both sides of the connecting section 25, and a long handle 34 is sleeved and connected to the surface of the connecting section 25;

[0032] One end of the long rod 22 is fixedly connected to the limit frame 23, and the surface of the limit frame 23 is symmetrically provided with a limit groove 24. The side surface of the connecting section 25 is symmetrically welded and fixed with a connecting frame 26 near one end. The other end surface of the connecting section 25 is fixedly connected to a docking block 27, and the side surface of the docking block 27 is fixedly connected to a protruding rod 28. The surface of the connecting frame 26 is provided with a hole groove, and the surface of the hole groove is sleeved with a connecting rod 33. The connecting rod 33 is rotatably connected to the connecting block 30. The inner side of the connecting block 30 is symmetrically fixedly connected to the limit rod 32, and the limit rod 32 is embedded in the limit groove 24.

[0033] A movable groove 2 is symmetrically provided on one end surface of the positioning frame 1, a supporting groove 3 is provided at the middle part of one end surface of the positioning frame 1, a slot 4 is provided inside the positioning frame 1 near the other end, a mounting groove 5 is provided inside the positioning frame 1 near the slot 4, the other end surface of the positioning frame 1 is fixedly connected to a mounting frame 6, a threaded groove 7 is provided on the surface of the mounting frame 6, a screw rod 8 is rotatably connected to the surface of the mounting groove 5, a straight rod 11 is embedded in the surface of the movable groove 2, a special-shaped block 14 is embedded in the surface of the slot 4, and a support rod 17 is symmetrically welded and fixed to the surface of one long side of the mounting frame 6;

[0034] A limit joint 9 is symmetrically welded and fixed on the surface of the twisting rod 8 near the bottom end, and an eccentric block 10 is fixedly connected to the surface of the twisting rod 8 near the limit joint 9;

[0035] A convex section 12 is symmetrically fixedly connected to the surface of the straight rod 11 near one end, and a stop block 13 is fixedly connected to the surface of the other end of the straight rod 11. The convex sections 12 can cooperate with each other to limit the protruding portion of the special-shaped block 14 therein. When the special-shaped block 14 is affected and starts to move, the convex sections 12 can drive the straight rod 11 to move accordingly.

[0036] One end surface of the special-shaped block 14 is fixedly connected to a clamping rod 15, and the other end surface of the special-shaped block 14 is fixedly connected to a first spring 16. In the actual construction site environment, the general stainless steel pipe welding and docking device is large in size and inconvenient to carry, install and use. Manually holding the stainless steel pipe for welding is not only dangerous to operate, but also the welding process is not easy to operate, which easily affects the welding effect. When using this stainless steel pipe welding and docking device, the user can use the common tubular frame structure, first place the pipe body in the gap between the groove 3 and the abutment block 13, and then start to rotate continuously. When the rod 8 is twisted, the limit section 9 can cooperate with the installation groove 5 to maintain stable rotation, and the eccentric block 10 will slowly push the clamping rod 15 to move toward the first spring 16. At the same time, the special-shaped block 14 can also push the convex section 12 to drive the straight rod 11 to move in the movable groove 2 until the abutment block 13 is tightly against the surface of the pipe body. The friction between the eccentric block 10 and the clamping rod 15 is used to complete the positioning, thereby completing the positioning of the stainless steel pipe. By rotating the twisting rod 8 in the opposite direction, the unlocking can be easily completed. It is not only simple and convenient to operate, but also convenient for installation and use on the construction site.

[0037] A connecting rod 18 is fixedly connected to the surface of one of the supporting rods 17. A threaded groove is provided on the surface of the connecting rod 18. A screw block 19 is spirally connected to the surface of the connecting rod 18.

[0038] A threaded rod 21 is fixedly connected to the surface of the screw handle 20, and the threaded rod 21 is spirally connected to the thread groove 7. A second spring 29 is fixedly connected to one end surface of the connecting section 25, and a rubber pad 31 is fixedly connected to one end surface of the connecting block 30.

[0039] The surface of the long handle 34 is provided with a through hole, which is connected to the connecting rod 18. The surface of one end of the long handle 34 is symmetrically fixedly connected to the docking frame 35, and the facing surfaces of the two docking frames 35 are symmetrically fixedly connected to the sleeve blocks 36. After the device is positioned, for the welding needs of the stainless steel pipe, the user can sleeve one of the stainless steel pipes on the outside of the connecting block 30, and then rotate the long handle 34 to rotate it around the connecting rod 18, and the sleeve block 36 will cooperate with the protruding rod 28 to drive the connecting section 25 to move. As the connecting section 25 moves toward the limit frame 23, the connecting rod 33 located on the connecting frame 26 will also push the connecting block 30 to move to both sides of the limit frame 23, and the limit rod 32 cooperates with the limit groove 24 can make the connecting block 30 move horizontally until the rubber pad 31 is attached to the inner wall surface of the stainless steel tube, thereby playing the role of internal support, and then re-rotate the screw block 19 on the surface of the connecting rod 18 until the support rod 17 tightly clamps the long handle 34, thereby completing the clamping and fixation of one stainless steel tube, and then swinging it against another stainless steel tube for welding. During this process, the long handle 32 rotates with the axis centerline of the connecting rod 18 as the center of the circle, thereby driving the sleeve block 36 to move through the docking frame 35. Due to the hole structure on the surface of the connecting joint 25, the arc motion trajectory of the sleeve block 36 can be met to a certain extent, so as to avoid the situation of restricted movement in the process of internally supporting the stainless steel tube.

[0040] The working principle of the present invention: In the actual construction site environment, the general stainless steel pipe welding and docking device is large in size and inconvenient to carry, install and use. Manually holding the stainless steel pipe for welding is not only dangerous to operate and use, but also inconvenient to operate during the welding process, which can easily affect the welding effect. When using this stainless steel pipe welding and docking device, the user can use the common tubular frame structure, first place the pipe body in the gap between the groove 3 and the abutment block 13, and then start to rotate the screw rod 8 continuously. During this process, the limit section 9 can cooperate with the installation groove 5 to maintain rotation stability, and the eccentric block 10 will slowly push the clamping rod 15 toward the first spring 16. At the same time, the special-shaped block 14 can also push the convex section 12 to drive the straight rod 11 to move in the movable groove 2 until the abutment block 13 is tightly against the surface of the pipe body, thereby completing the positioning. By rotating the screw rod 8 in the opposite direction, it can be easily unlocked. The screw block 19 is rotated again on the surface of the connecting rod 18 until the support rod 17 tightly clamps the long handle 34, thereby completing the clamping and fixing of one stainless steel pipe, and then placing it against another stainless steel pipe for welding.

However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention.
