Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, and more specifically, to a stainless steel pipe for welding a support frame with a connecting structure. Background Technology

[0002] The support frame is made by welding stainless steel pipes, which can provide good support performance for the supported object. Therefore, multiple stainless steel pipes are needed in the welding process of the support frame. Stainless steel pipe is a hollow long round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, and machinery and instrumentation, as well as mechanical structural components.

[0003] However, there are various types of stainless steel pipes in the existing technology. For example, utility model patent CN222334727U involves a stainless steel pipe that is easy to install. This utility model includes a stainless steel pipe body, a connecting mechanism, and an installation mechanism. One end of the stainless steel pipe body is integrally formed with a connecting pipe. This easy-to-install stainless steel pipe allows the connecting pipe of one stainless steel pipe body to be inserted into the insert of another stainless steel pipe body, which facilitates the connection of the two stainless steel pipe bodies. During the insertion process, the connecting pipe will squeeze the spring piece, causing one end of the limiting plate to abut against the fixing groove. Through the setting of the arc surface, the limiting plate deforms and moves closer to the spring piece. Both the spring piece and the limiting plate are made of highly elastic stainless steel, which has good resilience. When the connecting pipe is fully inserted into the insert, the spring piece and the limiting plate rebound and snap into the slot. One side of the limiting plate is close to the inner wall of the slot, thereby fixing the connecting pipe and the insert. This completes the pre-fixation of the two stainless steel pipe bodies, which is convenient for workers to weld.

[0004] Although the stainless steel pipe can pre-fix two stainless steel pipes to facilitate welding, the two stainless steel pipes can only be horizontally joined. When used as a material for support frame construction, it is difficult to join the two stainless steel pipes at multiple angles, making it inconvenient for workers to weld the stainless steel pipes in multiple directions according to actual needs. This greatly limits its use. To avoid this, it is essential to design a stainless steel pipe for welding support frames with a connecting structure. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0028] like Figure 1 , Figure 4 as well as Figure 5The diagram shows the structure of the stainless steel pipe used for welding the support frame with a connecting structure in this embodiment. The stainless steel pipe in this embodiment includes a first stainless steel pipe 1. Two sets of fastening semi-rings 2 are symmetrically distributed on the outer surface of the first stainless steel pipe 1. Two symmetrical connecting rods 3 are fixedly connected between the two sets of fastening semi-rings 2. A drive shaft 4 is mounted on each of the distant surfaces of the two connecting rods 3 via bearings. A movable frame 5 is fixedly connected to one end of each of the two drive shafts 4. A threaded limiting rod 6 is fixed to one end of the movable frame 5. An installation sleeve 7 is fitted onto the surface of each threaded limiting rod 6. A support ring 8 is fixedly connected between the two installation sleeves 7. Two clamping plates 9 are movably arranged inside the support ring 8. A second stainless steel pipe 10 is fixed between the two clamping plates 9. A positioning sleeve 11 is threadedly connected to the surface of the threaded limiting rod 6, and the positioning sleeve 11 is located on one side of the installation sleeve 7. The threaded limiting rod 6 passes through the installation sleeve 7. Multiple adjusting knobs 12 are fixedly connected to the outer surface of the positioning sleeve 11. The two stainless steel pipes used for welding the support frame are then... First, two fastening half-rings 2 are joined and fixed to the outer surface of the first stainless steel pipe 1. Then, the movable frame 5 is deflected by the set transmission shaft 4. The two stainless steel pipes can be connected horizontally, vertically, or at a certain angle. According to the actual needs of the support frame welding, the movable frame 5 is rotated to the corresponding position. At this time, the second stainless steel pipe 10 to be spliced ​​is passed through the support ring 8 and placed between the two clamps 9. The second stainless steel pipe 10 is clamped and fixed by the two clamps 9. Then, the mounting sleeve 7 on the support ring 8 is respectively put on the two threaded limit rods 6. Then, the positioning sleeve 11 is tightened by the adjusting knob 12. The positioning sleeve 11 will press the support ring 8, so that the support ring 8 drives the second stainless steel pipe 10 to be tightly connected with the first stainless steel pipe 1. Thus, when welding stainless steel pipes to make support frames, the two stainless steel pipes can be connected at multiple angles, which is convenient for workers to weld stainless steel pipes in multiple directions according to actual needs, better meeting the needs of workers. Therefore, the stainless steel pipe with the connecting structure has few limitations.

[0029] like Figure 4As shown, in order to clamp the second stainless steel pipe 10 using two clamping plates 9, in this embodiment, the support ring 8 is provided with two symmetrical threaded rings. The inner surface of the threaded rings is threaded with a screw 19, and one end of the screw 19 is rotatably connected to the clamping plate 9. The clamping plate 9 is arc-shaped, and an anti-slip pad 20 is provided on the inner side of the clamping plate 9. The anti-slip pad 20 is attached to the second stainless steel pipe 10. The other end of the screw 19 is fixedly connected to a rotating handle 21. Two symmetrical guide rods 22 are fixedly connected to the clamping plate 9, and the guide rods 22 are slidably installed between the support ring 8. When the second stainless steel pipe 10 is placed between the two clamping plates 9, the two rotating handles 21 are adjusted respectively, and the ends of the screw 19 drive the two clamping plates 9 to move, so that the clamping plates 9 move closer to the second stainless steel pipe 10. Then, the clamping plates 9 are used to press the anti-slip pad 20 onto the second stainless steel pipe 10, thereby clamping and fixing the second stainless steel pipe 10 to be welded.

[0030] It is worth noting that, in order to limit the movement of the movable frame 5 after the angle is adjusted, such as... Figure 2 as well as Figure 3 As shown, in this embodiment, a limiting disk 13 is coaxially provided on the surface of one of the drive shafts 4. The limiting disk 13 has several slots 14, which are distributed at equal intervals. The connecting rod 3 has a guide groove 15 inside, and a slider 16 is slidably installed in the guide groove 15. A socket 17 is fixedly connected to the slider 16. A compression spring 18 is provided inside the guide groove 15. Pulling the socket 17 releases the socket 17 from the positioning of the limiting disk 13. When the drive shaft 4 rotates with the movable frame 5 by a corresponding angle, the drive shaft 4 will drive the limiting disk 13 to rotate together. At this time, by utilizing the elasticity of the compression spring 18, the compression spring 18 can press the slider 16 to make the socket 17 re-enter the corresponding slot 14, thereby fixing the adjusted movable frame 5.

[0031] In this embodiment, the socket 17 can be embedded inside the slot 14, and one end of the compression spring 18 is fixedly connected to the slider 16, and the compression spring 18 is in a compressed state.

[0032] like Figure 6As shown, this is a schematic diagram of the structure of the two fastening half-rings 2 after disassembly in this embodiment. In this embodiment, each set of fastening half-rings 2 includes two symmetrically distributed fastening half-rings 2. The inner surface of the fastening half-ring 2 is provided with a rubber sheet 24, and the rubber sheet 24 is attached to the first stainless steel tube 1. Two symmetrical mounting plates 23 are provided on the fastening half-ring 2. The mounting plates 23 are provided with mounting holes, and connecting bolts 25 are provided in the mounting holes. Connecting nuts 26 are threadedly connected to the surface of the connecting bolts 25. When fixing the two sets of fastening half-rings 2, the two symmetrically distributed fastening half-rings 2 are merged, and the rubber sheet 24 is pressed against the first stainless steel tube 1. Then, the connecting bolts 25 and connecting nuts 26 are tightened respectively, thereby fastening the mounting plates 23 and pressing the two fastening half-rings 2 against each other.
