Description

Technical Field

[0001] This invention relates to the field of copper pipe welding technology, specifically to a fixing device for welding copper pipes used in air conditioning systems. Background Technology

[0002] A copper pipe welding device is a piece of equipment installed at the joint of copper pipes, which can weld pipes of various materials.

[0003] Copper pipe fusion welding is a common method for connecting copper pipes, primarily used in building, industrial, and domestic plumbing systems. It involves heating the copper pipes to partially melt them, then joining two pipes together under pressure or using flux to form a sealed connection. Copper pipe fusion welding typically uses flame heating or resistance heating methods.

[0004] However, the following defects still exist after the above copper pipe connection is completed:

[0005] ① After the above copper pipes are connected, the two pipes can be connected to achieve the purpose of pipe connection. However, after the connection is completed, the workers directly place it in the working environment. Since some copper pipes need to be buried in the soil for protection, the outer wall of the joint is easily damaged by hard substances in the soil, which can cause the joint to crack, resulting in leakage of the copper pipe joint and affecting subsequent normal use.

[0006] ② In addition, compared with ordinary pressure vessels, copper pipes have poorer working conditions and are subjected to excessive pressure, especially at the pipe joints, i.e., the interface of the copper pipe. Therefore, during long-term operation, the pipe interface is subjected to greater stress, which causes the entire pipe to shift and then causes greater deformation at the pipe interface. This not only affects the flow of the medium inside the pipe, but also reduces the pipe's sealing performance.

[0007] Therefore, in view of this, the present invention proposes a fixing device for welding copper pipes in air conditioners to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a fixing device for welding copper pipes in air conditioning systems, thereby resolving the corresponding technical issues raised in the background section.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a copper tube body, and a positioning anti-cracking mechanism is provided on the outside of the copper tube body, and telescopic limiting mechanisms are installed on both sides of the positioning anti-cracking mechanism.

[0010] The positioning anti-cracking mechanism includes: a protective frame, a screw, a fixed shaft, an arc shell, a connecting plate, an adjusting rod, a rotating plate, a rotating shaft, and a groove. The fixed shaft is evenly distributed inside the protective frame. A groove is formed on the inner wall of the protective frame. A screw is installed on the upper surface of the protective frame. The lower end of the screw is rotatably connected to the arc shell. Connecting plates are fixedly connected to both sides of the arc shell. Adjusting rods are rotatably connected to both sides of the connecting plates. A rotating plate is rotatably connected to the end of the adjusting rod away from the connecting plate. A rotating shaft is installed in the middle of the rotating plate. The telescopic limiting mechanism includes: a connecting shaft, a connecting rod, a cylindrical shell, a fixed ring, a drill rod, and a limiting ring. A connecting shaft is fixedly connected to the end of the rotating shaft away from the rotating plate. A connecting rod is fixedly connected to the arc surface of the connecting shaft. A fixed ring is fitted onto the arc surface of the connecting shaft. A drill rod is fixedly connected to the end of the connecting shaft away from the protective frame. A limiting ring is fixedly connected to the arc surface of the drill rod. A cylindrical shell is fitted onto the arc surface of the fixed ring.

[0011] Preferably, in this invention, the upper surface of the protective frame has two placement slots, which are symmetrically distributed on both sides of the screw. A handle is installed inside the placement slot, and the handle has a U-shaped cross-section.

[0012] In a preferred embodiment of the present invention, the lower surface of the protective frame is fixedly connected to a fixing surface, and the surface of the fixing surface is uniformly provided with conical protrusions.

[0013] In a preferred embodiment of the present invention, both ends of the connecting plate are provided with circular slots, the inner walls of the circular slots are smooth and extend through the connecting plate from top to bottom, and the arc shell and the fixed shaft are slidably connected through the connecting plate.

[0014] In a preferred embodiment of the present invention, the rotating shaft extends through the protective frame on both sides, and the end of the rotating shaft near the adjusting rod is fixedly connected to the rotating plate.

[0015] In a preferred embodiment of the present invention, the arc surface of the fixing ring is provided with a sliding groove, the inner wall of the sliding groove is smooth, and the connecting rod and the fixing ring are rotatably connected through the sliding groove.

[0016] In a preferred embodiment of the present invention, the drill rod is provided with fixing plates evenly distributed on its arc surface, and a cylindrical shaft is fixedly connected to one side of the fixing plates that are close to each other. The arc surface of the cylindrical shaft is hinged with connecting claws.

[0017] Compared with the prior art, the beneficial effects achieved by the technical solution of the present invention are:

[0018] (1) After the workers connect the copper pipe body between the arc shells, since the arc shells are fixedly connected to both sides, and the arc shells are slidably connected to the fixed shaft through the connecting plates, when the screw is turned, the upper and lower parts of the arc shells fit tightly against the outer wall of the copper pipe body. The installation of the positioning anti-cracking mechanism can not only keep the interface of the copper pipe body stable and effectively prevent the interface of the copper pipe body from shifting and deforming, but also prevent the interface from being damaged by hard substances or corroded during long-term work, thereby improving the performance of the copper pipe body and extending its service life.

[0019] (2) Through the cooperation between the connecting shaft, connecting rod, cylindrical shell, fixing ring, sliding groove, drill rod, limiting ring, fixing plate, and connecting claw, since one end of the rotating shaft is fixedly connected to the rotating plate, the whole device will remain stable during use and will not change position, thus affecting the working state of the copper pipe body. Since the fixing plate and connecting claw are hinged and evenly distributed on the arc surface of the drill rod, after the drill rod extends out from the inside of the cylindrical shell, the pressure on the connecting claw inside the cylindrical shell disappears, so the connecting claw will automatically open, thus ensuring the firmness of the pipe joint during use.

[0020] (3) Two placement slots are opened on the upper surface of the protective frame and the placement slots are symmetrically distributed on both sides of the screw. A handle is installed inside the placement slot. The installation of the handle makes it easier for the staff to pick up the device. A fixing surface is fixedly connected to the lower surface of the protective frame. The surface of the fixing surface is uniformly provided with conical protrusions, which can increase the friction between the device and the ground and increase the stability of the device during operation.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Embodiments of the present invention

[0032] Please refer to Figure 1 As shown, a fixing device for welding copper pipes in air conditioners includes a copper pipe body 1, a positioning anti-cracking mechanism 2 is provided on the outside of the copper pipe body 1, and telescopic limiting mechanisms 3 are installed on both sides of the positioning anti-cracking mechanism 2.

[0033] Please refer to Figures 2 to 5 As shown, fixed shafts 24 are evenly arranged inside the protective frame 21. Grooves 29 are provided on the inner wall of the protective frame 21. Screws 22 are installed on the upper surface of the protective frame 21. The lower end of the screws 22 is rotatably connected to an arc shell 25. Connecting plates 2501 are fixedly connected to both sides of the arc shell 25. Adjusting rods 26 are rotatably connected to both sides of the connecting plate 2501. A rotating plate 27 is rotatably connected to the end of the adjusting rod 26 away from the connecting plate 2501. A rotating shaft 28 is installed in the middle of the rotating plate 27. Circular slots are provided at both ends of the connecting plate 2501. The inner wall of the circular slots is smooth and extends through the connecting plate 2501 vertically. The arc shell 25 and the fixed shafts 24 are slidably connected through the connecting plate 2501. The rotating shaft 28 extends through the protective frame 21 from left to right. The end of the rotating shaft 28 near the adjusting rod 26 is fixedly connected to the rotating plate 27.

[0034] The above structure can effectively prevent the copper tube body 1 from shifting and deforming at the interface, which would lead to internal flow blockage. It can also prevent the interface from being damaged by hard materials or corroded during long-term operation, thereby reducing the service life of the copper tube body 1.

[0035] Please refer to Figure 2 , Figure 3 As shown, the upper surface of the protective frame 21 has two placement slots, which are symmetrically distributed on both sides of the screw 22. A handle 23 is installed inside the placement slot. The handle 23 has a U-shaped cross section. The installation of the handle 23 makes it easier for workers to pick up the device.

[0036] The lower surface of the protective frame 21 is fixedly connected to a fixing surface 2101. The surface of the fixing surface 2101 is uniformly provided with conical protrusions. The conical protrusions can increase the friction between the device and the ground and increase the stability of the device during operation.

[0037] Please refer to Figures 6 to 8 As shown, a connecting shaft 31 is fixedly connected to the end of the rotating shaft 28 away from the rotating plate 27. A connecting rod 3101 is fixedly connected to the arc surface of the connecting shaft 31. A fixing ring 33 is fitted onto the arc surface of the connecting shaft 31. A drill rod 34 is fixedly connected to the end of the connecting shaft 31 away from the protective frame 21. A limit ring 35 is fixedly connected to the arc surface of the drill rod 34. A cylindrical shell 32 is fitted onto the arc surface of the fixing ring 33. A sliding groove 3301 is formed on the arc surface of the fixing ring 33. The inner wall of the sliding groove 3301 is smooth. The connecting rod 3101 and the fixing ring 33 are connected through the sliding groove 3301. The drill rod 34 is rotated and connected. Fixed plates 36 are evenly arranged on the arc surface of the drill rod 34. A cylindrical shaft is fixedly connected to one side of the fixed plates 36 that are close to each other. A connecting claw 37 is hinged to the arc surface of the cylindrical shaft. The telescopic limiting mechanism 3 can extend into the soil on both sides to keep the entire device stable during use and prevent positional changes that could affect the working state of the copper tube body 1. After the drill rod 34 extends out of the inside of the cylindrical shell 32, the pressure on the connecting claw 37 inside the cylindrical shell 32 disappears, so the connecting claw 37 will automatically open, thereby enhancing the stability of the drill rod 34.

[0038] The complete usage steps and working principle of the above embodiments are as follows:

[0039] This device is mainly used for sewage treatment plants, sewage discharge treatment in factories and mines, etc., and is installed and used at the interface of double-walled copper pipes.

[0040] Initial state: such as Figure 1 and Figure 2As shown, the two are the initial states of the equipment at different angles. At this time, the handle 23 is reset in the placement groove on the upper surface of the protective frame 21, and the screw 22 is furthest away from the upper surface of the protective frame 21. Since the lower end of the screw 22 is connected to the upper half of the arc shell 25, the upper and lower parts of the arc shell 25 are separated in this state, and the rotating plate 27 remains in an inclined static state in the groove 29. Since the positioning anti-cracking mechanism 2 and the telescopic limit mechanism 3 are linked through the rotating shaft 28, the telescopic limit mechanism 3 also remains static. At this time, the connecting rod 3101 is located above the slide groove 3301, and the drill rod 34 remains static inside the cylindrical shell 32.

[0041] In use: After the worker connects the copper pipe body 1 between the arc shells 25, since both sides of the arc shell 25 are fixedly connected to the connecting plates 2501, and the arc shell 25 is slidably connected to the fixed shaft 24 through the connecting plates 2501, when the screw 22 is rotated, since the lower end of the screw 22 is rotatably connected to the upper part of the arc shell 25, the screw 22 drives the upper part of the arc shell 25 to move from top to bottom. Because the connecting plates 2501 are rotatably connected to the two sides of the adjusting rods 26, and the other ends of the adjusting rods 26 are respectively fixed to the two sides of the rotating plate 27, during the downward movement of the upper part of the arc shell 25, it will drive... The rotating plate 27 rotates in the groove 29. At this time, the lower half of the arc shell 25 will move upward with the rotation of the rotating plate 27 until the screw 22 is attached to the upper surface of the protective frame 21. At this time, the upper and lower parts of the arc shell 25 are tightly attached to the outer wall of the copper tube body 1. The installation of the positioning anti-cracking mechanism 2 can not only keep the interface of the copper tube body 1 stable and effectively prevent the interface of the copper tube body 1 from shifting and deforming, thus causing internal flow blockage, but also prevent the interface from being damaged by hard substances or corroded during long-term operation, thereby reducing the service life of the copper tube body 1.

[0042] Meanwhile, since one end of the rotating shaft 28 is fixedly connected to the rotating plate 27, and the other end of the rotating shaft 28 passes through the side wall of the protective frame 21 and is fixedly connected to the connecting shaft 31, the connecting shaft 31 will rotate along with the rotating shaft 28. At this time, the connecting rod 3101 fixedly connected to the arc surface of the connecting shaft 31 will slide along the groove 3301 opened on the arc surface of the fixing ring 33. Due to the rotation and compression of the connecting shaft 31, the limiting ring 35 will extend out from the inside of the cylindrical shell 32 until the limiting ring 35 fixedly connected to the arc surface of the drill rod 34 is stuck in the cylindrical shell 32. At the outlet of 2, since the copper pipe body 1 is mainly used underground, the telescopic limiting mechanism 3 can extend into the soil on both sides, so that the entire device remains stable during use and will not change position, thereby affecting the working state of the copper pipe body 1. Since the fixing plate 36 and the connecting claw 37 are hinged and evenly distributed in a circular pattern on the arc surface of the drill rod 34, after the drill rod 34 extends out from the inside of the cylindrical shell 32, the pressure on the connecting claw 37 inside the cylindrical shell 32 disappears, so the connecting claw 37 will automatically open, thereby enhancing the stability of the drill rod 34.

[0043] After use: Finally, after the device has finished operating on the interface of the copper tube body 1, the staff will carry out subsequent processing.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
