Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe bending technology, specifically a stainless steel pipe with adjustable docking direction. Background Technology

[0002] Stainless steel bends are a type of stainless steel shaped pipe. They are made by bending stainless steel pipes into different shapes and angles through a specific process. They come in various types, have good performance, and are widely used in various fields of life. However, some problems still occur in the actual use of existing stainless steel bends.

[0003] For example, patent application number CN202022516144.6 discloses a stainless steel bend, including two straight sections at both ends, several inner straight sections with both ends aligned, and several bends. The two straight sections at both ends are parallel to each other, and the inner straight sections are arranged between the two straight sections at both ends. Adjacent straight sections at both ends and inner straight sections, as well as adjacent inner straight sections, are connected end to end by bends. This design improves the efficiency of pressure testing after assembly. Most existing stainless steel bends have a simple structure. After installation, when adjusting the connection direction of the bend according to actual needs, it is inconvenient for workers to make adjustments. The bend needs to be completely disassembled before installation.

[0004] To address the aforementioned problems, a stainless steel bend with adjustable docking direction is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel bend with adjustable docking direction. By using this device, the problem is solved that most existing stainless steel bends have a simple structure, and after installation, it is inconvenient for workers to adjust the docking direction according to the actual situation, requiring the bend to be completely disassembled before installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel bend with adjustable docking direction, comprising a stainless steel pipe body and a bend body disposed at one end of the stainless steel pipe body. One end of the stainless steel pipe body is fixedly connected to a mounting box. The bend body is rotatably connected to one side of the mounting box. The mounting box is provided with an adjustment mechanism, which adjusts the direction of the bend body. The adjustment mechanism includes knobs rotatably connected to the upper and lower sides of the mounting box. A baffle is slidably connected inside the stainless steel pipe body. A fixing pipe is also fixedly connected inside the mounting box. Protrusions are fixedly connected to both the upper and lower sides of the fixing pipe. The bend body is rotatably connected to the fixing pipe.

[0007] Preferably, a transmission screw is fixedly connected to the bottom of the knob, the transmission screw is threadedly connected to the baffle, and the baffle matches the protrusion.

[0008] The design using the above structure allows the transmission screw to rotate via a knob, and the baffle to be displaced via a threaded connection. When the baffle separates from the protrusion, the bending tube body can rotate freely to adjust its direction. When the baffle returns to its original position and presses against the protrusion, it can fix the bending tube body in place. This design enables rapid adjustment and stable locking of the bending tube direction. It is simple to operate and does not require disassembly of the entire structure, thus solving the problem of complete disassembly required for traditional bending tube adjustment.

[0009] Preferably, one end of the stainless steel tube body extends into the interior of the stainless steel tube body and is fixedly connected to a contact tube. A slot assembly is provided on one side of the contact tube, and a sealing ring is also fixedly connected inside the contact tube.

[0010] With the above-mentioned structural design, the contact tube extends into the interior of the stainless steel tube body. Its slotted assembly cooperates with the locking block assembly of the bend body to provide a positioning reference for the rotation of the bend, ensuring accurate direction after adjustment. The sealing ring fits snugly with the sealing tube, maintaining good sealing performance after the bend is rotated and adjusted, preventing fluid leakage, and improving the sealing performance and reliability of the pipeline connection.

[0011] Preferably, a spring rod is fixedly connected to both the upper and lower sides of the stainless steel pipe body, a transmission block is fixedly connected to the top of the spring rod, and a rotating rod is rotatably connected to the top of the transmission block.

[0012] With the above-mentioned structure, the spring rod provides elastic support for the transmission block, and the rotating rod can rotate around the transmission block. By controlling the position of the rotating rod, the knob can be locked or unlocked. This elastic linkage structure provides a flexible way to fix the knob, making it easy for operators to quickly switch the working state of the knob and enhancing the ease of use of the device.

[0013] Preferably, a friction block one is fixedly connected to the bottom of the rotating rod near one end, a friction block two is fixedly connected to the top of the knob, and a spring rod two is fixedly connected to one side of the protrusion.

[0014] With the above-mentioned structure, when friction block one and friction block two are in contact, the friction force restricts the rotation of the knob, preventing it from rotating accidentally due to external forces; spring rod two applies elastic thrust to the protrusion, which can cause it to automatically reset after the bend is adjusted, ensuring that the locking block group and the locking groove group are tightly engaged. The double limit design improves the stability of the device and prevents the bend from loosening or the knob from being misoperated after adjustment.

[0015] Preferably, one end of the second spring rod is fixedly connected to the inside of the mounting box, and one end of the bent tube body is fixedly connected to a sealing tube.

[0016] With the above-mentioned structural design, the second spring rod is fixed inside the mounting box, providing continuous reset elasticity for the bend body, ensuring that the bend can automatically fit with the contact pipe after adjustment; the sealing pipe and sealing ring match, further enhancing the sealing effect at the pipe connection, and can effectively prevent fluid leakage even after frequent direction adjustments, making it suitable for various fluid transportation scenarios.

[0017] Preferably, a locking block assembly is fixedly connected to one side of the bent pipe body, the locking block assembly slides in conjunction with the locking groove assembly, and the sealing pipe matches the sealing ring.

[0018] The above-mentioned structural design, with the sliding cooperation of the locking block group and the locking groove group, not only provides guidance for the rotation of the bent pipe, but also enables precise positioning through locking after adjustment, ensuring the stability of the bent pipe's direction. The tight fit between the sealing tube and the sealing ring forms a double sealing guarantee. Combined with the mechanical positioning of the locking block and the locking groove, the bent pipe has both stability and sealing after the direction is adjusted, improving the overall performance of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application, through the setting of knobs, locking blocks, locking slots, and baffles, enables workers to easily adjust the docking direction of the bent pipe body, improves the effectiveness of the device, and solves the problem that most existing stainless steel bent pipes have a simple structure, and after installation, it is inconvenient for workers to adjust the docking direction according to the actual situation, requiring the bent pipe to be completely disassembled before installation.

[0021] 2. This application, through the setting of a pull rod, friction block one, friction block two, and spring rod one, achieves the function of preventing the knob from rotating when not in use, which saves more manpower and solves the problem that most existing stainless steel bend adjustment components lack a fixed structure, and the knob may rotate when subjected to external force, thus affecting the stability of the device.

[0030] Combination Figures 1-4 An adjustable stainless steel bend includes a stainless steel pipe body 1 and a bend body 2 disposed at one end of the stainless steel pipe body 1. One end of the stainless steel pipe body 1 is fixedly connected to a mounting box 11. The bend body 2 is rotatably connected to one side of the mounting box 11. The mounting box 11 is provided with an adjustment mechanism, which adjusts the direction of the bend body 2. The adjustment mechanism includes knobs 111 rotatably connected to the upper and lower sides of the mounting box 11. A baffle 12 is slidably connected inside the stainless steel pipe body 1. A fixing pipe 212 is also fixedly connected inside the mounting box 11. Protrusions 21 are fixedly connected to the upper and lower sides of the fixing pipe 212. The bend body 2 is rotatably connected to the fixing pipe 212.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that most existing stainless steel bends have a simple structure, making adjustments to the bend's alignment after installation inconvenient for workers and requiring complete disassembly before reinstallation, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a transmission screw 112 is fixedly connected to the bottom of the knob 111. The transmission screw 112 is threadedly connected to the baffle 12. The baffle 12 matches the protrusion 21. One end of the stainless steel tube body 1 extends into the interior of the stainless steel tube body 1 and is fixedly connected to a contact tube 13. A slot assembly 131 is opened on one side of the contact tube 13. A sealing ring 132 is also fixedly connected inside the contact tube 13. A spring rod 211 is fixedly connected to one side of the protrusion 21. One end of the spring rod 211 is fixedly connected to the interior of the mounting box 11. A sealing tube 221 is fixedly connected to one end of the bent tube body 2. A locking block assembly 22 is fixedly connected to one side of the bent tube body 2. The locking block assembly 22 and the slot assembly 131 slide together. The sealing tube 221 matches the sealing ring 132. During use, the stainless steel tube body 1 can be installed in a designated position. When necessary, it can be installed according to the actual situation. When adjusting the direction of the bend body 2, the knob 111 can be turned first. The knob 111 drives the transmission screw 112 to rotate, thereby moving the baffle 12. After the baffle 12 moves away from one side of the protrusion 21, the bend body 2 can be pulled. The bend body 2 drives the sealing tube 221 to move, thereby moving the locking block group 22 out of the inside of the locking groove group 131. At this time, the bend body 2 can be rotated. The rotation of the bend body 2 can adapt to pipes in different positions. After the adjustment is completed, the bend body 2 can be released. Under the action of the spring rod 211, the bend body 2 returns to its original position, thereby making the sealing tube 221 fit with the sealing ring 132, and the locking block group 22 engage with the locking groove group 131, thus completing the adjustment of the bend body 2. This realizes the function of making it convenient for workers to adjust the docking direction of the bend body 2, improving the use effect of the device.

[0034] Example 2:

[0035] To address the issue that most existing stainless steel pipe bending adjustment components lack a fixed structure, and that knob 111 may rotate under external force, thus affecting the stability of the device, this embodiment discloses the following technical solution, specifically as follows: Figure 5As shown, spring rods 14 are fixedly connected to both the upper and lower sides of the stainless steel pipe body 1. A transmission block 141 is fixedly connected to the top of the spring rod 14. A rotating rod 142 is rotatably connected to the top of the transmission block 141. A friction block 143 is fixedly connected to the bottom of the rotating rod 142 near one end. A friction block 144 is fixedly connected to the top of the knob 111. When the knob 111 needs to be rotated, the rotating rod 142 can be pulled first. The rotating rod 142 drives the friction block 143 to move, thereby separating the friction block 143 from the friction block 144. At this time, the knob 111 can be rotated. After rotation, the rotating rod 142 can be rotated so that the friction block 143 at the bottom of the rotating rod 142 is aligned with the friction block 144. Finally, the rotating rod 142 is released, and the friction block 143 and the friction block 144 are in contact. This effectively prevents the knob 111 from rotating, thus preventing the knob 111 from rotating when not in use and saving manpower.
