Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe joints, specifically a stainless steel pipe joint with stable connection. Background Technology

[0002] Stainless steel is short for stainless and acid-resistant steel. Steels resistant to weak corrosive media such as air, steam, and water, or those possessing rust-resistant properties, are called stainless steel. Steels resistant to chemical corrosion media (acids, alkalis, salts, etc.) are called acid-resistant steel. Due to differences in their chemical composition, their corrosion resistance differs. Ordinary stainless steel is generally not resistant to chemical corrosion, while acid-resistant steel generally possesses rust-resistant properties. The term "stainless steel" does not refer to a single type of stainless steel, but rather to over one hundred types of industrial stainless steel. Each type of stainless steel developed has excellent performance in its specific application field. Pipes made of stainless steel have a longer service life and adaptability due to the unique properties of stainless steel, leading to their increasingly widespread application. To facilitate the connection of stainless steel pipes, specialized connectors for stainless steel pipes are now available on the market.

[0003] A search revealed that existing patent [CN 211976171 U] discloses a stainless steel pipe connector with safety valves, including a pipe joint. Safety valves are installed at both ends of the pipe joint. A connecting pipe is fixedly connected to the end of the safety valve away from the pipe joint. A movable pipe is threaded onto the external side of the connecting pipe. A limit ring is fixedly connected to the end of the connecting pipe away from the safety valves. Multiple clamping plates, arranged in a clustered shape and fixedly connected to the movable pipe, are arranged inside the limit ring. This utility model, with its connection between the stainless steel pipe and the pipe joint, and the safety valves on both sides of the pipe joint, allows for rapid control of the conveying operation in case of problems within the conveying system, thus quickly terminating the entire conveying process. This not only prevents material leakage but also enhances the connection stability between the clamping plates and the stainless steel pipe, making the connection between the connector and the stainless steel pipe more secure and safer to use. This stainless steel pipe connector solves the problem that if the stainless steel pipe is damaged, these connectors cannot effectively control the pipe, which may not only lead to material waste but also dangerous accidents.

[0004] While the aforementioned utility model patent addresses the problem that damaged stainless steel pipes cannot be effectively controlled by these connectors, potentially leading to material waste and even dangerous accidents, most currently used stainless steel pipe joints are inconvenient to install and cannot seal the pipe-joint connection. If the pipe and joint are not securely installed, they may loosen or even detach after prolonged use, resulting in poor installation stability. Since these joints are typically used to transport liquids such as water, the inability to seal the connection can lead to leaks, wasting resources and compromising the environmental friendliness of the joint. Furthermore, they hinder flow control of the transported water, negatively impacting user experience and causing water waste. This could even damage equipment requiring high water flow rates, thus limiting the joint's applicability. Utility Model Content

[0005] The purpose of this invention is to provide a stable stainless steel pipe joint to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable stainless steel pipe joint, comprising a connecting block, with a joint body fixedly connected to both ends of the connecting block, a sealing mechanism provided on the top of the connecting block, the sealing mechanism including threads, threads inside the connecting block, threads on the inner wall of the joint body, a reserved groove provided on the top of the connecting block, a sealing ring provided inside the reserved groove, the sealing ring being used to form a seal at the connection point of the connecting block, a fixed cylinder slidably connected to the outer wall of the joint body, a sealing ring fixedly connected to the inner wall of the fixed cylinder, a lower clamp fixedly connected to one side of the fixed cylinder, a rotating shaft fixedly connected to one side of the lower clamp, a rotating plate rotatably connected to the outer wall of the rotating shaft, a connecting rod fixedly connected to one side of the rotating plate, an upper clamp fixedly connected to one end of the connecting rod, mounting plates fixedly connected to the bottom of the upper clamp and the top of the lower clamp, bolts fitting against the inner wall of the mounting plates, and nuts threadedly connected to the outer wall of the bolts.

[0007] As a preferred technical solution, the number of the connector bodies is two, and the two connector bodies are symmetrically arranged with the vertical center line of the connector block as the axis of symmetry.

[0008] As a preferred technical solution, the number of the fixing cylinders is two, and the two fixing cylinders are symmetrically arranged with the vertical center line of the connecting block as the axis of symmetry.

[0010] As a preferred technical solution, the outer wall of the connector body is provided with a flow control mechanism, the flow control mechanism includes a valve, and the valve is fixedly connected to the outer wall of the connector body.

[0011] As a preferred technical solution, the number of valves is two, and the two valves are symmetrically arranged with the vertical center line of the connecting block as the axis of symmetry.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the installation and sealing mechanism, facilitates the installation and connection of pipes and joints and seals the connection between them. During use, the pipes and joints are connected through the threaded engagement, and the sealing ring seals the connection. This prevents the pipes and joints from loosening or even detaching after prolonged use due to insecure installation, ensuring the installation stability of the joint. It also avoids water leakage at the connection between the joint and pipe due to the inability to seal the connection, thus preventing resource waste and ensuring the environmental friendliness and practicality of the joint.

[0014] 2. This utility model, through the setting of the flow control mechanism, can facilitate the control of the water flow during transportation. During use, the flow of water during transportation can be controlled by turning the valve. This also avoids situations where the user experience is affected and water resources are wasted due to the inconvenience of flow control, and may even damage some equipment that requires water flow speed. This ensures the applicability of the connector. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 As shown, the present invention provides the following technical solution, including a connecting block 1, with connector bodies 4 fixedly connected to both ends of the connecting block 1, a sealing mechanism 2 installed on the top of the connecting block 1, two connector bodies 4, and the two connector bodies 4 are symmetrically arranged with the vertical center line of the connecting block 1 as the axis of symmetry, and a flow control mechanism 3 is provided on the outer wall of the connector body 4.

[0024] Specifically: When the stainless steel pipe fitting is needed to connect stainless steel pipes, the stainless steel pipe must first be installed and connected to the top of the fitting body 4 and the connecting block 1. The stainless steel pipe is installed onto the stainless steel pipe fitting using the installation sealing mechanism 2. After installation, the connection between the pipe and the fitting body 4 needs to be sealed using the installation sealing mechanism 2. Once connected, the pipe and the stainless steel fitting can be used to transport water resources. During the transport process, the flow rate of water resources in the pipe and fitting body 4 needs to be adjusted using the flow control mechanism 3 to control the water flow rate, thereby completing the work.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the top of the connecting block 1 is provided with a sealing mechanism 2, which includes a thread 201. The connecting block 1 has a thread 201 inside, and the inner wall of the connector body 4 has a thread 201. The top of the connecting block 1 is provided with a reserved groove, and a sealing ring 202 is provided inside the reserved groove. The sealing ring 202 is used to form a seal at the connection point of the connecting block 1. A fixed cylinder 203 is slidably connected to the outer wall of the connector body 4. The sealing ring 202 is fixedly connected to the inner wall of the fixed cylinder 203. A lower clamp 204 is fixedly connected to one side of the fixed cylinder 203. A rotating shaft 205 is fixedly connected to one side of the lower clamp 204. A rotating shaft 205 is rotatably connected to the outer wall of the rotating shaft 205. A connecting rod 207 is fixedly connected to one side of plate 206 and rotating plate 206. An upper clamp 208 is fixedly connected to one end of the connecting rod 207. Mounting plates 209 are fixedly connected to the bottom of the upper clamp 208 and the top of the lower clamp 204. Bolts 210 are attached to the inner wall of mounting plate 209. Nuts 211 are threadedly connected to the outer wall of bolts 210. There are two fixing cylinders 203, and the two fixing cylinders 203 are symmetrically arranged with the vertical center line of connecting block 1 as the axis of symmetry. A through hole is opened inside the mounting plate 209. The shape and size of the through hole match the shape and size of the bolt 210, and the mounting plate 209 is attached to the bolt 210.

[0026] When using this stainless steel pipe fitting to connect stainless steel pipes, the stainless steel pipe must first be installed and connected to the top of the fitting body 4 and the connecting block 1. The pipe is then inserted into the through hole at the top of the connecting block 1. The pipe is then rotated, and its threads 201 align with the threads 201 in the through hole, fixing the pipe to the top of the connecting block 1. Next, the threads 201 on the pipe are aligned with the threads 201 inside the fitting body 4. The pipe is then rotated, and its threads 201 on the inner wall of the fitting body 4 and the outer wall of the stainless steel pipe are engaged, rotating the pipe into the fitting body 4 for fixation. This completes the installation. After installation, the connection between the pipe and the fitting body 4 needs to be sealed using the sealing ring 202. Then, the upper clamp 20 is adjusted. 8. By rotating the rotating plate 206 outside the rotating shaft 205, the upper clamp 208 can be pried open. After the upper clamp 208 is pried open, the fixing cylinder 203 will be delivered. At this time, the fixing cylinder 203 is moved to the middle position of the connection between the connector body 4 and the pipe. Then, the upper clamp 208 is pried open so that the mounting plate 209 on the upper clamp 208 is in contact with the mounting plate 209 on the lower clamp 204. Then, the bolt 210 is passed through the through hole on the mounting plate 209, and then the nut 211 is rotated into the outside of the bolt 210, so that the nut 211 and the bolt 210 cooperate to fix the mounting plate 209. By fixing the mounting plate 209, the sealing ring 202 in the fixing cylinder 203 is fixed at the connection, so that the sealing ring 202 in the fixing cylinder 203 seals the connection between the pipe and the connector body 4, thereby completing the sealing work.

[0027] like Figure 1 and Figure 6 As shown, a flow control mechanism 3 is provided on the outer wall of the connector body 4. The flow control mechanism 3 includes a valve 301. The valve 301 is fixedly connected to the outer wall of the connector body 4. There are two valves 301, and the two valves 301 are symmetrically arranged with the vertical center line of the connector block 1 as the axis of symmetry.

[0028] Once connected, water can be transported using the pipe and the stainless steel connector. During the transport process, it is necessary to adjust the flow rate of the water in the pipe and connector body 4 by turning the valve 301 to adjust the flow rate and thus complete the flow control work.

[0029] The working principle of this utility model is as follows: When the stainless steel pipe fitting is needed to connect stainless steel pipes, the stainless steel pipe first needs to be installed and connected to the top of the fitting body 4 and the connecting block 1. At this time, the pipe is inserted into the through hole at the top of the connecting block 1, and then the pipe is rotated. Through the thread 201 on the pipe and the thread 201 in the through hole, the pipe is fixed to the top of the connecting block 1. Then, the thread 201 on the pipe is aligned with the thread 201 inside the fitting body 4. Then, the pipe is rotated. Through the cooperation of the thread 201 on the inner wall of the fitting body 4 and the thread 201 on the outer wall of the stainless steel pipe, the pipe is rotated into the interior of the fitting body 4 for fixing, thus completing the installation work. After installation, the connection between the pipe and the fitting body 4 needs to be sealed. Through the sealing ring 202, the connection between the connecting block 1 and the pipe is sealed. Then, the upper clamp 208 is bent. Through the rotation of the rotating plate 206 outside the rotating shaft 205, the upper clamp 208 can be bent. After bending, the fixing cylinder 203 will be delivered. At this time, move the fixing cylinder 203 to the middle position of the connection between the connector body 4 and the pipe. Then, bend the upper clamp 208 so that the mounting plate 209 on the upper clamp 208 is in contact with the mounting plate 209 on the lower clamp 204. Then, pass the bolt 210 through the through hole on the mounting plate 209, and then rotate the nut 211 into the outside of the bolt 210. This makes the nut 211 and the bolt 210 fit together, fixing the mounting plate 209. By fixing the mounting plate 209, the sealing ring 202 in the fixing cylinder 203 is fixed at the connection, so that the sealing ring 202 in the fixing cylinder 203 seals the connection between the pipe and the connector body 4, thus completing the sealing work. After the connection is completed, the pipe and the stainless steel connector can be used to transport water resources. During the transportation process, it is necessary to adjust the flow rate of water resources in the pipe and connector body 4. The flow rate of water resources is adjusted by turning the valve 301, thus completing the flow control work.
