Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel composite pipes, in particular to a stainless steel lined composite pipe. Background Art

[0002] A composite pipe is an innovative pipe product, which is composed of two or more different materials skillfully combined to present a multi-layer structure. To prevent the composite pipe from rusting and scaling, a stainless steel lined composite pipe is needed.

[0003] After retrieval, the Chinese patent publication number is: CN208845894U, which discloses a stainless steel lined composite pipe, including a carbon steel pipe and a stainless steel pipe. The first pipe head and the second pipe head are respectively welded to the left end and the right end of the carbon steel pipe and the stainless steel pipe, so that the pipe head, the carbon steel pipe and the stainless steel pipe form an independent cavity. Inside the cavity, aluminum foil, aerogel felt and foamed cotton sleeve are arranged in sequence from inside to outside, realizing that the aluminum foil reflects heat radiation, and the aerogel felt and the foamed cotton sleeve have low thermal conductivity to reduce heat loss and ensure the heat preservation function. And the liquid conveyed will not directly contact the layer structure, improving the stability. Moreover, the aluminum foil, the aerogel felt and the foamed cotton sleeve are thin in thickness and will not increase the installation difficulty. By arranging an inner groove on the inner wall of the left end of the first pipe head and an outer groove on the outer wall of the right end of the second pipe head, an internal thread and an external thread are integrally formed on the inner wall of the inner groove and the outer wall of the outer groove respectively, realizing the screwing connection of the internal thread and the external thread to achieve the function of convenient connection. However, when the device is actually used, the composite pipe cannot be bent and adjusted according to needs to meet the use requirements in different environments, thus reducing the practicability of the device. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a stainless steel lined composite pipe, aiming to improve the problem that the composite pipe cannot be adjusted in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a stainless steel lined composite pipe, including a hose, both the upper and lower sides of the outer wall of the hose are communicated with composite pipes. The front side of the upper composite pipe is fixedly connected with a U-shaped plate. A rotating plate is rotatably connected inside the U-shaped plate. A moving rod is rotatably connected to the outside of the rotating plate. The outside of the moving rod is slidably connected with a hollow plate. The rear side of the hollow plate is fixedly connected with the lower composite pipe. A rack is fixedly connected to the inside of the moving rod. A gear is rotatably connected to the inside of the hollow plate. The gear is meshed with the rack. A positioning mechanism is arranged on the outside of the composite pipe, and the positioning mechanism is used to fix the device.

[0006] Through the above technical solution: when adjusting the rotation angle of the pipeline, rotate the rotating plate in the front U-shaped plate of the upper composite pipe. The rotating plate drives the moving rod to slide in the hollow plate. At this time, the rack inside the moving rod moves accordingly. Since the inside of the hollow plate is rotatably connected to the gear and the gear meshes with the rack, during the movement of the rack, the gear rotates, thereby realizing the adjustment of the angle of the lower composite pipe relative to the upper composite pipe.

[0007] As a further description of the above technical solution:

[0008] The positioning mechanism includes two rotating rings, and the two rotating rings are respectively rotatably connected to the outer sides of the corresponding composite pipes.

A belt is arranged on the outer side of the rotating wheel, and the two rotating wheels are connected by the belt for transmission. The outer side of the rotating wheel penetrates through the fixed frame and is fixedly connected to a threaded rod, and a positioning sleeve is threadedly connected to the outer side of the threaded rod.

[0009] Through the above technical solution: the two rotating rings rotate on the outer sides of the composite pipes respectively. Inside the fixed frame on the front side of the rotating ring, the upper and lower rotating wheels are connected by a belt for transmission. When the rotating wheel rotates, the threaded rod on its outer side also rotates. Since the positioning sleeve is threadedly connected to the threaded rod, the rotation of the threaded rod causes the positioning sleeve to move, thereby realizing the fixation of the equipment.

[0010] As a further description of the above technical solution:

[0011] The front side of the U-shaped plate is rotatably connected to an indicating block. The outer side of the indicating block penetrates through the U-shaped plate and is fixedly connected to the rotating plate. A plurality of indicating grooves are fixedly connected to the front side of the U-shaped plate.

[0012] Through the above technical solution: when the rotating plate rotates, it can drive the indicating block to rotate at the same time, making it point to the corresponding indicating groove, and the current rotation angle can be known.

[0013] As a further description of the above technical solution:

[0014] The outer side of the hollow plate is rotatably connected to a knob. The outer side of the knob penetrates through the hollow plate and is fixedly connected to the gear.

[0015] Through the above technical solution: the gear can be easily driven to rotate by the knob.

[0016] As a further description of the above technical solution:

[0022] As a further description of the above technical solution:

[0023] A U-shaped block is fixedly connected to the outer wall of the composite pipe, and a connecting plate is rotatably connected to the inner side of the U-shaped block.

[0024] Through the above technical solution: The connecting plate can fix the composite pipe.

[0025] As a further description of the above technical solution:

[0026] A plugging rod is slidably connected to the inner side of the fixing frame, and the plugging rod is engaged with the connection hole.

[0027] Through the above technical solution: The engagement of the plugging rod and the connection hole facilitates the fixing of the rotating ring.

[0028] The utility model has the following beneficial effects:

[0029] 1. In the utility model, when it is necessary to adjust the rotation angle of the pipeline, the rotating plate in the U-shaped plate on the front side of the upper composite pipe is rotated. The rotating plate drives the moving rod to slide in the hollow plate, so that the rack on the inner side of the moving rod moves. Since the gear on the inner side of the hollow plate is engaged with the rack, the gear rotates when the rack moves, and the angle adjustment of the lower composite pipe relative to the upper composite pipe can be realized, thereby improving the practicability of the device.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Reference Figure 1 、 Figure 3 and Figure 4 The utility model provides an embodiment: a lined stainless steel composite pipe, including a hose 1, the upper and lower sides of the outer wall of the hose 1 are connected with composite pipes 3, the front side of the upper composite pipe 3 is fixedly connected with a U-shaped plate 4, the inner side of the U-shaped plate 4 is rotatably connected with a rotating plate 6, the outer side of the rotating plate 6 is rotatably connected with a moving rod 7, the outer side of the moving rod 7 is slidably connected with a hollow plate 5, the rear side of the hollow plate 5 is fixedly connected to the lower composite pipe 3, the inner side of the moving rod 7 is fixedly connected with a rack 9, the inner side of the hollow plate 5 is rotatably connected with a gear 8, the gear 8 is meshed with the rack 9, and a positioning mechanism 2 is provided on the outer side of the composite pipe 3, which is used to fix the device;

[0040] Specifically, when the rotation angle of the pipeline needs to be adjusted, first, the rotating plate 6 inside the U-shaped plate 4 on the front side of the upper composite pipe 3 needs to be rotated. The rotation of the rotating plate 6 will drive the moving rod 7 to move along its sliding track inside the hollow plate 5. Since a rack 9 is arranged on the inner side of the moving rod 7, the rack 9 will also move accordingly during the movement. At this time, a rotatably connected gear 8 is arranged on the inner side of the hollow plate 5, and the gear 8 and the rack 9 are mutually matched by meshing. The movement of the rack 9 causes the corresponding rotation of the gear 8, and the rotation of the gear 8 drives the lower composite pipe 3 to adjust the angle relative to the upper composite pipe 3, ensuring the precise positioning and adjustment of the pipeline.

[0041] Refer to Figure 1 , Figure 2 and Figure 5 , the positioning mechanism 2 includes two rotating rings 201. The two rotating rings 201 are respectively rotatably connected to the outer sides of the corresponding composite pipes 3. A fixing frame 204 is fixedly connected to the front side of the rotating ring 201. Rotating wheels 202 are rotatably connected to the upper and lower sides of the inner wall of the fixing frame 204. A belt 203 is arranged on the outer sides of the rotating wheels 202, and the two rotating wheels 202 are connected by belt 203 for transmission. The outer side of the rotating wheel 202 penetrates through the fixing frame 204 and is fixedly connected with a threaded rod 205. A positioning sleeve 206 is threadedly connected to the outer side of the threaded rod 205;

[0042] Specifically, the two rotating rings 201 are respectively installed on the outer sides of the composite pipes 3 for rotation. The front sides of these rotating rings 201 are provided with fixing frames 204. The inner part of the fixing frame 204 is provided with rotating wheels 202 on the upper and lower sides. These rotating wheels 202 are connected by belt 203 for transmission, forming a coordinated transmission system. When the rotating wheel 202 starts to rotate, the threaded rod 205 on its outer side will also rotate accordingly. There is a threaded connection between the threaded rod 205 and the positioning sleeve 206. This threaded connection enables the rotation of the threaded rod 205 to cause the axial movement of the positioning sleeve 206. Through this movement mechanism, the positioning sleeve 206 can accurately move to the predetermined position, thereby realizing the stable fixation of the equipment and ensuring the stability and accuracy of the equipment during operation.

[0043] Refer to Figure 1 , Figure 2 and Figure 3 , a indicating block 11 is rotatably connected to the front side of the U-shaped plate 4. The outer side of the indicating block 11 penetrates through the U-shaped plate 4 and is fixedly connected with the rotating plate 6. A plurality of indicating grooves 12 are fixedly connected to the front side of the U-shaped plate 4; A knob 10 is rotatably connected to the outer side of the hollow plate 5. The outer side of the knob 10 penetrates through the hollow plate 5 and is fixedly connected with the gear 8; A handle 15 is fixedly connected to the outer side of the composite pipe 3. A sheath 16 is fixedly connected to the middle of the outer side of the handle 15;

[0044] Specifically, by rotating the rotating plate 6, the rotation of the indicating block 11 can be driven simultaneously. The design of the indicating block 11 enables it to point to the cooperating indicating groove 12 during its rotation. The setting of the indicating groove 12 allows the operator to intuitively understand the current rotation angle by observing the pointing of the indicating block 11. By rotating the knob 10, the gear 8 can be effectively driven to rotate, thereby realizing the adjustment of the relevant mechanism. This design not only improves the convenience of operation but also ensures that the rotation of the gear 8 can stably and precisely control the angle adjustment of the lower composite pipe 3. The design of the handle 15 enables the operator to easily hold the entire device, thus realizing stable operation. The sheath 16 provides additional protection and comfort, making the handle 15 safer and more comfortable during use.

[0045] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, on the outer side of the composite pipe 3, a flange plate 17 is fixedly connected, and a plurality of connection holes 18 are opened on the outer side of the flange plate 17; on the outer wall of the composite pipe 3, a U-shaped block 13 is fixedly connected, and a connecting plate 14 is rotatably connected inside the U-shaped block 13; inside the fixed frame 204, a plugging rod 19 is slidably connected, and the plugging rod 19 is engaged with the connection hole 18.

[0046] Specifically, through the flange plate 17 and the connection holes 18 thereon, the installation and fixation of the device become more convenient. The flange plate 17 provides a stable installation base. Through the connection holes 18, the device can be firmly fixed to the support structure. Through the U-shaped block 13 and the inner connecting plate 14, the effective fixation of two composite pipes 3 can be realized. The structural design of the U-shaped block 13 enables it to tightly clamp the two composite pipes 3, while the connecting plate 14 provides additional support and stability. By moving the plugging rod 19 to engage it with the corresponding connection hole 18, it is ensured that the rotating ring 201 can be firmly fixed at the predetermined position. This engaging mechanism not only improves the stability of the device but also simplifies the installation process of the rotating ring 201.

[0047] Working principle: Before using this device, when the rotation angle of the pipeline needs to be adjusted, first, the rotating plate 6 in the U-shaped plate 4 on the front side of the upper composite pipe 3 should be rotated. When the rotating plate 6 is adjusted, it will drive the moving rod 7 to slide inside the hollow plate 5. Since a rack 9 is provided inside the moving rod 7, it will move correspondingly as the moving rod 7 moves. The gear 8 connected to the rack 9 inside the hollow plate 5 will also rotate accordingly. This is because the meshing relationship between the gear 8 and the rack 9 causes the movement of the rack 9 to directly result in the rotation of the gear 8, thereby realizing the angle adjustment of the lower composite pipe 3 relative to the upper composite pipe 3.

[0048] It rotates by being respectively installed on the outer side of the composite pipe 3 through two rotating rings 201. Inside the fixing frame 204 on the front side of the rotating ring 201, the upper and lower rotating wheels 202 are drivingly connected through a belt 203. When the rotating wheel 202 starts to rotate, the threaded rod 205 on its outer side will also rotate accordingly. The threaded rod 205 and the positioning sleeve 206 are matched with each other by means of threaded connection, which means that the rotation of the threaded rod 205 will cause the positioning sleeve 206 to move along the axial direction of the threaded rod 205. Such a motion mechanism enables the positioning sleeve 206 to accurately adjust and fix the position of the device, thereby ensuring the stability and reliability of the device.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
