Description

Technical Field

[0001] The utility model relates to the technical field of copper pipe elbow connection, in particular to a copper pipe elbow connection device. Background Technique

[0002] Due to a series of physical property advantages, copper pipes are widely used in many industries. These advantages include a hard texture, high temperature resistance, high pressure resistance, and relatively light weight. In addition, copper pipes have excellent thermal conductivity and can still maintain high strength in low temperature environments. During installation, in order to adjust the pipeline direction, accessories such as copper pipe elbows are usually required.

[0003] Under the background of traditional technology, the following steps are generally taken when installing a copper pipe elbow: First, align and connect the elbow with a flange to the corresponding end of the copper pipe, and then complete the entire installation process by tightening the bolts on the flange. However, in actual use, especially after long-term use, the installed elbow may become blocked. Workers usually need to use tools or manually screw the bolts on the flanges at both ends of the elbow to disassemble or clean the blockage. This manual operation is not only time-consuming and laborious, but also suitable tools may not be available on site, which seriously affects work efficiency and increases the complexity of the work. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, especially after long-term use, the installed elbow may become blocked, and workers usually need to use tools or manually screw the bolts on the flanges at both ends of the elbow to disassemble or clean the blockage. This manual operation is not only time-consuming and laborious, but also suitable tools may not be available on site, which seriously affects work efficiency and increases the complexity of the work, and a copper pipe elbow connection device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A copper pipe elbow connection device includes an elbow pipe and a straight pipe. Fixed rings are fixedly connected to the ports of the elbow pipe and the straight pipe. A plurality of screw holes are opened on the fixed ring, and fixing bolts are threadedly installed in the screw holes;

[0007] A moving structure for driving the linear movement adjustment of the elbow pipe is arranged on the fixed ring;

[0008] The moving structure includes a sleeve arranged on the opposite sides of the elbow pipe and the straight pipe. One end of the sleeve close to the elbow pipe is fixedly connected with a first installation ring. The first installation ring corresponds to the fixed ring, and the first installation ring is threadedly connected with the fixing bolt. Threads are arranged on the inner wall of the sleeve;

[0009] A driving member for facilitating the user to drive the sleeve to move is provided on the straight pipe;

[0010] The driving member includes a second mounting ring provided on the opposite side of the elbow pipe and the straight pipe. One end of the second mounting ring relative to the elbow pipe is fixedly connected with a limiting ring. The second mounting ring is threadedly connected with the fixing bolt. A threaded cylinder is rotatably connected inside the limiting ring, and the threaded cylinder is threadedly connected with the sleeve.

[0011] Preferably, a rotating ring is fixedly sleeved on the outer side wall of the threaded cylinder. A rotating groove corresponding to the rotating ring is provided on the inner wall of the limiting ring, and the rotating ring is rotatably connected with the rotating groove.

[0012] Preferably, a ring groove for facilitating the rotation of the threaded cylinder is provided on the limiting ring, and the threaded cylinder is rotatably connected with the side wall of the second mounting ring close to the elbow pipe.

[0013] Preferably, the second mounting ring is fixed relative to the straight pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the setting of the moving structure of the present utility model, the sleeve with internal threads is arranged on the opposite side of the elbow pipe and the straight pipe. The first mounting ring corresponding to the fixing ring is fixed at one end of the sleeve close to the elbow pipe. The threaded cylinder threadedly connected with the sleeve can rotate freely inside the limiting ring. When the staff needs to inspect or clean the inside of the elbow pipe, they only need to simply turn the threaded cylinder. As the threaded cylinder rotates, the sleeve will move along the thread direction, thereby driving the fixing ring, the mounting ring and the elbow pipe to move together, and finally effectively showing one port of the elbow pipe. This process does not require manually turning the bolts or operating with tools that must be adapted by the user, greatly simplifying the operation steps, reducing the work difficulty, making the whole inspection and cleaning process faster, and thus saving a lot of time and labor.

[0016] 2. Through the setting of the fixing bolt, the fixing ring, the first mounting ring and the second mounting ring of the present utility model, the fixing ring is respectively fixed at the ports of the elbow pipe and the straight pipe. A plurality of screw holes are designed on the fixing ring, and the screw holes are threadedly connected with the fixing bolt. When it is necessary to replace or maintain connection components such as the threaded cylinder or the sleeve, the staff only need to simply turn the fixing bolt to easily remove these components together. This design effectively avoids the problem of insufficient sealing caused by long-term use, thereby ensuring the normal operation and use of the entire pipeline system. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1-6 , a copper pipe elbow connection device, including an elbow pipe 1 and a straight pipe 2. Fixing rings 3 are fixedly connected to the ports of the elbow pipe 1 and the straight pipe 2. A plurality of screw holes are provided on the fixing ring 3, and fixing bolts 4 are threadedly installed in the screw holes; the setting of the fixing bolts 4 enables the user to easily disassemble, assemble or replace the elbow pipe 1 during subsequent use of the device, greatly improving the maintainability and service life of the device, and the screw holes and the fixing bolts 4 provide a reliable and effective fastening method.

[0026] A moving structure for driving the linear movement adjustment of the elbow pipe 1 is provided on the fixing ring 3.

[0027] The moving structure includes a sleeve 5 provided on the opposite sides of the elbow pipe 1 and the straight pipe 2. One end of the sleeve 5 close to the elbow pipe 1 is fixedly connected with a first installation ring 6. The first installation ring 6 corresponds to the fixing ring 3, and the first installation ring 6 is threadedly connected with the fixing bolt 4. Threads are provided on the inner wall of the sleeve 5; the threaded connection of both the first installation ring 6 and the fixing ring 3 with the fixing bolt 4 ensures the stability of the entire device and provides a convenient operation method for the user.

[0028] A driving member for facilitating the user to drive the movement of the sleeve 5 is provided on the straight pipe 2.

[0029] The driving member includes a second mounting ring 7 disposed on the opposite side of the curved pipe 1 and the straight pipe 2. The second mounting ring 7 is fixedly connected to a limit ring 8 at one end of the curved pipe 1. The second mounting ring 7 is threadedly connected to the fixing bolt 4. A threaded barrel 9 is rotatably connected inside the limit ring 8, and the threaded barrel 9 is threadedly connected to the sleeve 5. The user can rotate the threaded barrel 9 to make the sleeve 5 move synchronously with the curved pipe 1 in the same direction. This design greatly facilitates the user's subsequent inspection of the interior of the curved pipe 1 and effectively prevents the curved pipe 1 from being blocked.

[0030] A rotating ring 10 is fixedly sleeved on the outer wall of the threaded barrel 9, and a rotating groove 11 corresponding to the rotating ring 10 is opened on the inner wall of the limiting ring 8, and the rotating ring 10 and the rotating groove 11 are rotatably connected. The arrangement of the rotating ring 10 and the rotating groove 11 ensures that the threaded barrel 9 can rotate smoothly and continuously in the limiting ring 8, further improving the operating efficiency and reliability of the entire driving component.

[0031] The limiting ring 8 is provided with an annular groove 12 for facilitating the rotation of the threaded barrel 9, and the threaded barrel 9 is rotatably connected to the side wall of the mounting ring 27 near the elbow 1. The provision of the annular groove 12 ensures that the threaded barrel 9 can rotate smoothly during operation. The presence of the annular groove 12 not only enables the threaded barrel 9 to fit tightly against the outer side wall of the straight pipe 2, but also helps to ensure the connection sealing performance of the straight pipe 2 during use, effectively preventing any possible leakage, thereby ensuring the integrity and safety of the pipeline system.

[0032] The mounting ring 2 7 is fixed relative to the straight pipe 2, thus ensuring the stability and durability of the entire device.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] When the staff needs to check the inside of the elbow 1 to determine whether there is a blockage, they can manually hold the elbow 1 and perform necessary limiting. Then, by screwing one of the threaded barrels 9, this action will cause the threaded barrel 9 to rotate, and then drive the rotating ring 10 to rotate accordingly in the rotating groove 11. At the same time, the rotation of the threaded barrel 9 will also cause the sleeve 5 to move in a specific direction. Since the sleeve 5 is closely connected to the mounting ring 6, the fixing ring 3 and the straight pipe 2, the movement of the sleeve 5 will drive these components to move together. This mechanical linkage ultimately allows one port of the elbow 1 to be effectively displayed, greatly facilitating the staff's inspection of the inside of the elbow 1 and creating conditions for subsequent cleaning operations. The entire operation process does not require manual tightening of bolts or the use of tools that must be adapted by the user, which not only simplifies the operating steps, but also saves time and labor;

[0035] After long-term use, if the elbow pipe 1 needs to be replaced, the staff can achieve this by screwing the fixing bolt 4. After unscrewing and removing the fixing bolt 4, the separation between the elbow pipe 1 and the straight pipe 2 can be easily achieved, thus providing convenience for replacing the elbow pipe 1. This design not only improves the maintenance efficiency of the equipment but also reduces the maintenance cost, ensuring that the pipeline system can quickly resume normal operation.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
