Description

Technical Field

[0001] This utility model relates to the field of stainless steel shaped tube technology, specifically a high-strength stainless steel shaped tube. Background Technology

[0002] Stainless steel shaped pipes refer to all stainless steel pipes with shapes other than circular cross-sections. Due to their excellent bending strength, they are widely used in building load-bearing support structures. When used to manufacture door and window frames, they combine lightweight and high strength, offering over 40% better bending and torsional resistance than round pipes. This makes them particularly suitable for load-bearing structural designs and extends the service life of the pipes.

[0003] When using existing high-strength stainless steel special-shaped tubes, most of them need to be connected by welding, which makes the operation more complicated. Furthermore, the welded stainless steel special-shaped tubes need to be cut when dismantling, making it inconvenient to disassemble and replace them later. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength stainless steel shaped tube to solve the problem of inconvenience in disassembling stainless steel shaped tubes mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength stainless steel shaped tube, comprising a first shaped tube body, a insertion tube, and a second shaped tube body. The first shaped tube body has an insertion tube at its top end, and the insertion tube has a second shaped tube body at its top end. A stabilizing locking mechanism is provided at one end of the first shaped tube body. The stabilizing locking mechanism includes a fixing frame at one end of the first shaped tube body, a rotating wheel at one end of the fixing frame, and a rotating rod extending into the interior of the fixing frame at one end of the rotating wheel.

[0006] Preferably, a threaded rod is provided inside the fixed frame near one end of the rotating rod, and a bevel gear set is connected between the threaded rod and the rotating rod. A movable seat extending to the outside of the fixed frame is provided on the surface of the threaded rod.

[0007] Preferably, the top of the movable seat is provided with a connecting plate, and the top of the connecting plate is provided with a pull hook.

[0008] Preferably, the hook has a T-shaped block inside that connects to the connecting plate, and a fixing rod is provided at one end of the second shaped tube body near the hook.

[0009] Preferably, the surfaces of the first and second shaped tube bodies are provided with a protective sealing mechanism, which includes a protective ring disposed on the surfaces of the first and second shaped tube bodies, and the protective rings are symmetrically distributed on the surfaces of the first and second shaped tube bodies.

[0010] Preferably, each of the two protective rings has a mounting plate at one end, one mounting plate has a docking block on one side, and the other mounting plate has symmetrically distributed limiting plates inside.

[0011] Preferably, one end of the limiting plate is provided with a pull rod extending to the outside of the mounting plate, a spring is welded between the two limiting plates, and a locking rod extending into the docking block is provided on one side of the limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The high-strength stainless steel shaped tube is first subjected to sandblasting hardening on its surface to improve its hardness during use. The hook is then separated from the fixing rod to allow for quick disassembly of the stainless steel shaped tube, avoiding the difficulty of disassembly after welding.

[0014] 2. This high-strength stainless steel shaped tube, by inserting two locking rods into the connecting block, allows the protective ring to lock onto the surfaces of the first and second shaped tube bodies. This protects the connection point and prevents the stable locking mechanism from rusting due to prolonged contact with air, which would make subsequent disassembly more inconvenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 It can be seen that this utility model provides a technical solution:

[0023] exist Figure 1 In the first shaped tube body 1, a plug tube 2 is provided at the top end, and a second shaped tube body 3 is provided at the top end of the plug tube 2. A stabilizing locking mechanism 4 is provided at one end of the first shaped tube body 1. The stabilizing locking mechanism 4 includes a fixing frame 401 provided at one end of the first shaped tube body 1, a rotating wheel 402 provided at one end of the fixing frame 401, and a rotating rod 403 extending into the interior of the fixing frame 401 provided at one end of the rotating wheel 402.

[0024] This high-strength stainless steel shaped tube can be inserted into the first shaped tube body 1 through the second shaped tube body 3, and then the rotating wheel 402 can drive the rotating rod 403 to rotate.

[0025] exist Figure 4 In the middle: a threaded rod 404 is provided at one end of the fixed frame 401 near the rotating rod 403. A bevel gear set 405 is connected between the threaded rod 404 and the rotating rod 403. A movable seat 406 extending to the outside of the fixed frame 401 is provided on the surface of the threaded rod 404.

[0026] This high-strength stainless steel shaped tube can drive the bevel gear set 405 to rotate when the rotating rod 403 rotates. At the same time, the bevel gear set 405 can drive the threaded rod 404 to rotate when it rotates, so that the threaded rod 404 drives the moving seat 406 on the surface to move when it rotates.

[0027] exist Figure 4In the middle: The top of the movable seat 406 is provided with a connecting plate 407, and the top of the connecting plate 407 is provided with a hook 408.

[0028] This high-strength stainless steel shaped tube can drive the connecting plate 407 and the hook 408 to move upward when the moving seat 406 moves.

[0029] exist Figure 4 In the middle: The hook 408 is provided with a T-shaped block 409 that is connected to the connecting plate 407, and a fixing rod 410 is provided at one end of the second special-shaped tube body 3 near the hook 408.

[0030] This high-strength stainless steel shaped tube, when the hook 408 moves to one side of the fixing rod 410, the hook 408 can be rotated to hook onto the surface of the fixing rod 410, thereby enabling the first shaped tube body 1 and the second shaped tube body 3 to be stably locked together.

[0031] See Figures 1-4 It can be seen that, firstly, the surface of the stainless steel shaped tube is sandblasted and hardened to improve its hardness during use, thus providing better strength. Then, the hook 408 is rotated, causing the T-block 409 to rotate, making the hook 408 more stable during rotation. Next, the second shaped tube body 3 is fitted onto the surface of the insertion tube 2. Simultaneously, the movement of the second shaped tube body 3 causes the fixed rod 410 to move. Then, the rotating wheel 402 is rotated, causing the rotating rod 403 to rotate. The rotating rod 403, in turn, drives the bevel gear set 405 on its surface to rotate, and the bevel gear set 405, in turn, drives the threaded rod 404. The threaded rod 404 is rotated, causing the movable seat 406 to move. The movable seat 406, in turn, moves the connecting plate 407 at the top, which in turn moves the hook 408. When the hook 408 moves to a certain position, it is rotated so that it can be fitted onto the surface of the fixed rod 410. This locks the second shaped tube body 3 and the first shaped tube body 1 together, preventing gaps during use. Alternatively, the hook 408 can be separated from the fixed rod 410 for quick disassembly, avoiding the difficulty of disassembly after welding.

[0032] See Figures 1-3 and Figure 5 It can be seen that,

[0033] exist Figure 5In the middle: the surfaces of the first shaped tube body 1 and the second shaped tube body 3 are provided with a protective sealing mechanism 5. The protective sealing mechanism 5 includes a protective ring 501 disposed on the surfaces of the first shaped tube body 1 and the second shaped tube body 3. The protective rings 501 are symmetrically distributed on the surfaces of the first shaped tube body 1 and the second shaped tube body 3.

[0034] This high-strength stainless steel shaped tube allows the two protective rings 501 to be combined by setting protective rings 501 on the surfaces of the first shaped tube body 1 and the second shaped tube body 3.

[0035] exist Figure 5 In the middle: each of the two protective rings 501 has a mounting plate 502 at one end, a docking block 503 is provided on one side of one mounting plate 502, and symmetrically distributed limiting plates 504 are provided inside the other mounting plate 502.

[0036] This high-strength stainless steel shaped tube allows the mounting plates 502 at one end of the protective rings 501 to merge when the two protective rings 501 are combined. At the same time, the mating block 503 on one side of one mounting plate 502 can be inserted into the other mounting plate 502, thereby limiting the position of the protective rings 501.

[0037] exist Figure 5 In the middle: One end of the limiting plate 504 is provided with a pull rod 505 extending to the outside of the mounting plate 502, and a spring 506 is welded between the two limiting plates 504. A locking rod 507 extending into the docking block 503 is provided on one side of the limiting plate 504.

[0038] This high-strength stainless steel shaped tube uses two locking rods 507 to lock the mating block 503, thereby enabling the protective ring 501 to be locked on the surfaces of the first shaped tube body 1 and the second shaped tube body 3.

[0039] See Figures 1-3 and Figure 5It can be seen that by pinching the two pull rods 505 together, the pull rods 505 can drive the limiting plate 504 to move when they move. When the limiting plate 504 moves, it can squeeze the spring 506 on one side. When the limiting plate 504 moves, it can drive the locking rod 507 on one side to move. Then, the protective rings 501 are merged, so that the mounting plate 502 at one end of the protective ring 501 can be merged. And the docking block 503 can be inserted into the interior of the mounting plate 502. Then, the pull rods 505 are loosened. Through the reset effect of the spring 506, the locking rod 507 can be inserted into the interior of the docking block 503. This allows the protective ring 501 to lock the surfaces of the first shaped tube body 1 and the second shaped tube body 3. The protective ring 501 can protect the connection, preventing the stable locking mechanism 4 from rusting after long-term use due to contact with air, which would make subsequent disassembly more inconvenient. This gives the stainless steel shaped tube a better protective effect during use.

[0040] In summary, firstly, the surface of the stainless steel shaped tube is sandblasted to harden it, thereby increasing its hardness and strength during use. Then, the hook 408 is rotated, and the second shaped tube body 3 is fitted onto the surface of the insertion tube 2. Simultaneously, the movement of the second shaped tube body 3 moves the fixing rod 410. Rotating the wheel 402 moves the moving seat 406, which in turn moves the connecting plate 407 and the hook 408 at the top. When the hook 408 moves to... After reaching a certain position, rotate the hook 408 so that it can be fitted onto the surface of the fixing rod 410. This allows the hook 408 to lock the fixing rod 410, thus achieving a stable lock between the second shaped tube body 3 and the first shaped tube body 1, preventing gaps during use. Conversely, the hook 408 can be separated from the fixing rod 410, allowing for quick disassembly and avoiding difficulties in disassembly after welding.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
