Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to stainless steel pipe connection structures. Background Technology

[0002] Pipeline connection assemblies are crucial components of fluid systems, and it is essential to ensure that the pipeline remains leak-free during operation. Traditional pipeline connection techniques, which use threaded connections between the connecting pipe and the fitting body, often suffer from unreliable sealing, leading to liquid leaks, significantly reducing work efficiency, and potentially causing accidents.

[0003] For example, patent application number CN202121315559.5 discloses a stainless steel pipe connection assembly, belonging to the field of mechanical technology. It solves the problems of poor sealing, easy leakage, and environmental unfriendliness of existing pipe connection assemblies. This stainless steel pipe connection assembly includes a connecting pipe and a connecting joint inserted into one end of the connecting pipe. A locking nut is fitted on the outside of the connecting pipe and threadedly connected to the connecting joint. Both the connecting joint and the connecting pipe are made of stainless steel. One end of the connecting pipe is a conical section, which is flared. The outer end of the connecting joint has a second conical section, which matches the first conical section and is inserted inside the first conical section. The inner end face of the locking nut has a tapered surface that abuts against the outer wall of the first conical section. However, because the locking nut used to fasten the connecting joint and the connecting pipe is mounted on the outside of the connection structure, it is prone to corrosion after prolonged use, especially in humid environments. This leads to difficulties in removing the nut when replacing the pipe, requiring further optimization. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a stainless steel pipe connection structure, including connectors and a protective cover.

[0026] The connector includes a tee seat 3, and three pipe fittings 5 ​​are provided on the outside of the tee seat 3. The pipe fittings 5 ​​are fixedly connected to the tee seat 3, and a stainless steel pipe 4 is threaded onto the pipe fittings 5.

[0027] The pipe fitting 5 is connected to the stainless steel pipe 4 by threads. After installation, tighten the ferrule nut on the pipe fitting 5 to achieve a tight fit by squeezing the stainless steel pipe 4 with the ferrule nut.

[0028] The protective cover includes a bottom cover 1 and a top cover 2. The bottom cover 1 is fixedly installed at the lower end of the tee pipe seat 3. The back of the top cover 2 is rotatably connected to the back of the bottom cover 1 through a rotating shaft 11. The bottom cover 1 and the top cover 2 are engaged.

[0029] Multiple arc-shaped grooves 6 are provided at the connection between the bottom cover 1 and the top cover 2. The stainless steel tube 4 passes through the arc-shaped grooves 6. The left and right sides of the bottom cover 1 are provided with a pin structure to prevent the bottom cover 1 from separating from the top cover 2.

[0030] After the three stainless steel pipes 4 are installed, rotate the top cover 2 and place it on the upper end of the bottom cover 1. The top cover 2 and the bottom cover 1 are locked together, and the stainless steel pipe 4 passes through the arc groove 6 between the bottom cover 1 and the top cover 2. The bottom cover 1, together with the top cover 2, wraps the tee pipe seat 3, the pipe joint 5, and the connection between the stainless steel pipe 4 and the pipe joint 5, thereby improving the impact resistance of the tee pipe seat 3. The setting of the pin structure ensures that the top cover 2 and the bottom cover 1 will not separate, while not affecting the opening of the top cover 2, which is convenient for maintenance and repair.

[0031] It is worth explaining in detail that the bottom of the top cover 2 is provided with multiple spherical buckles 17, which are fixedly connected to the top cover 2. The top of the bottom cover 1 is provided with multiple spherical slots 18, which engage with the spherical buckles 17. After the top cover 2 is placed on top of the bottom cover 1, the spherical buckles 17 at the bottom of the top cover 2 will engage with the spherical slots 18 at the top of the bottom cover 1, thus initially limiting the position of the top cover 2 through the engaging structure.

[0032] Regarding the pivot structure:

[0033] The pin structure includes a pin plate 9 and a slot 15. The pin plate 9 is detachably connected to the left and right sides of the bottom cover 1. The slot 15 is opened on the left and right sides of the top cover 2. The upper end of the pin plate 9 is provided with a rotating shaft 11, which is rotatably connected to the pin plate 9. The upper end of the rotating shaft 11 is provided with a semi-circular baffle 12, which is fixedly connected to the rotating shaft 11. The semi-circular baffle 12 is placed on one side of the slot 15 and is slidably connected to the slot 15.

[0034] In the locked state, rotate the semi-circular stop 12 to slide it into the slot 15 from one side. The semi-circular stop 12, in conjunction with the slot 15, will limit the top cover 2 from both sides, preventing it from separating from the bottom cover 1 and ensuring a secure connection between them. To unlock, simply rotate the semi-circular stop 12 to pull it out of the slot 15; unlocking is quick and easy.

[0035] To facilitate the rotation of the rotating shaft 11, a handle 14 is provided at the upper end of the rotating shaft 11, and the handle 14 is fixedly connected to the rotating shaft 11. When rotating the semi-circular baffle 12, simply engage the handle 14 to rotate it.

[0036] To increase the stability of the mating point between the semicircular baffle 12 and the slot 15, a rubber pad 13 is wrapped around the outside of the semicircular baffle 12, and the rubber pad 13 has strip-shaped protrusions on its outer side. When the semicircular baffle 12 is screwed into the slot 15, the rubber pad 13 on the outside of the semicircular baffle 12 will be in close contact with the slot 15. The rubber pad 13 can absorb some vibration energy, reduce the rigid collision between the top cover 2 and the semicircular baffle 12, reduce the amplitude of vibration transmitted to the semicircular baffle 12 and the top cover 2, and extend the service life of the structure.

[0037] More specifically, fixing bolts 10 are fitted on both sides of the bolt plate 9. The fixing bolts 10 pass through the bolt plate 9 and are threadedly connected to the bolt holes opened on the outside of the bottom cover 1. When removing the entire screw pin structure, the fixing bolts 10 on the bolt plate 9 and the bottom cover 1 can be released.

[0038] To facilitate the user's opening of the top cover 2 from the top of the bottom cover 1, in a preferred embodiment, the front of the top cover 2 is provided with a handle 8, and a connecting bolt 16 is mounted on the handle 8. The connecting bolt 16 passes through the handle 8 and is threadedly connected to a bolt hole on the outside of the top cover 2. An arc-shaped groove 6 is provided on the back of the bottom cover 1 and the top cover 2. When opening the top cover 2, after releasing the locking mechanism of the top cover 2, the user can grasp the handle 8 and pull the top cover 2 upwards.

[0039] In the preferred embodiment, a sealing ring 7 is provided on the inner side of the arc-shaped groove 6, and the sealing ring 7 is fixedly connected to the top cover 2. The sealing ring 7 can tightly fit the outer wall of the stainless steel pipe 4, preventing external dust, moisture, oil, solid particles, etc. from entering the interior of the bottom cover 1 and the top cover 2 through the gap of the arc-shaped groove 6, causing pollution or corrosion. If liquid, gas, or other media are transported in the pipeline, the sealing ring can effectively seal the gap between the arc-shaped groove 6 and the stainless steel pipe 4, preventing the media from leaking from the connection point and avoiding safety hazards or environmental pollution.

[0040] How this application works:

[0041] The pipe fitting 5 is threaded to the stainless steel pipe 4. After the stainless steel pipe 4 is connected, tighten the ferrule nut on the pipe fitting 5. The ferrule nut will secure the stainless steel pipe 4. After the three stainless steel pipes 4 are installed, rotate the top cover 2 and place it on top of the bottom cover 1. The top cover 2 and the bottom cover 1 are engaged. The stainless steel pipe 4 passes through the arc-shaped groove 6 between the bottom cover 1 and the top cover 2. The bottom cover 1, together with the top cover 2, wraps around the tee fitting 3, the pipe fitting 5, and the connection between the stainless steel pipe 4 and the pipe fitting 5, improving the impact resistance of the tee fitting 3. The setting of the pin structure ensures that the top cover 2 and the bottom cover 1 will not separate, while not affecting the opening of the top cover 2, which is convenient for maintenance and repair.
