Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe connectors, and in particular to a stainless steel pipe connector that is easy to assemble and disassemble. Background Technology

[0002] Stainless steel pipe fittings are key components used to connect stainless steel pipes, achieving a sealed and secure connection in the piping system. They encompass various types, including elbows, tees, straight fittings, and flanges, and are made of high-quality stainless steel such as 304 and 316. These fittings possess excellent corrosion resistance, high-temperature resistance, and high-pressure resistance, with a smooth surface that resists scaling, effectively reducing fluid transport resistance. They also exhibit good mechanical strength and impact resistance. Widely used in industries such as chemical, food, medical, and building water supply and drainage, they ensure tight, safe, and reliable connections in the piping system through welding, crimping, and threaded connections, guaranteeing stable fluid transmission.

[0003] Existing stainless steel pipe fittings often lack precise guiding structures during installation. Installers need to rely on experience to repeatedly adjust the pipe position and angle, which is time-consuming and prone to installation deviations, resulting in low connection efficiency. At the same time, existing fittings are defective in terms of the stability of the pipe connection after it is established. They lack an effective and stable support structure, which can easily lead to pipe loosening, displacement, or even leakage and other safety accidents when subjected to external impacts or vibrations of the pipe system. Therefore, we propose a stainless steel pipe fitting that is easy to install and disassemble. Utility Model Content

[0004] The purpose of this utility model is to provide a stainless steel pipe connector that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe connector that is easy to assemble and disassemble, comprising a connecting mechanism and a stabilizing guide mechanism disposed on its outer side. The stabilizing guide mechanism includes a stabilizing base, and the stabilizing base is connected to two sets of rotating frames through two sets of rotating grooves on the upright. The bottom of each set of rotating frames is provided with a sliding groove, and each set of rotating frames is connected to a guide stabilizing collar through an extension rod. A limit collar frame is fixedly installed at the upper end of the upright.

[0006] As a preferred embodiment, the upright is fixedly installed at the center of the upper surface of the stable base, and two sets of rotating slots are formed on the outer wall of the upright, with two sets of rotating frames rotatably connected inside the two sets of rotating slots respectively.

[0007] As a preferred embodiment, the extension rod is slidably connected inside the rotating frame, and a sliding block is fixedly installed on the lower surface of the extension rod near one end. The sliding block is slidably connected inside the sliding groove, and the guide stabilizing collar is fixedly installed on the lower surface of the extension rod near the other end.

[0008] As a preferred embodiment, the connecting mechanism includes a connecting pipe, with mating grooves extending through all four sides of the connecting pipe, wherein two sets of mating grooves are internally threaded with sealing thread plugs.

[0009] As a preferred embodiment, the other two sets of docking grooves are each fitted with a connecting pipe, and both ends of the connecting pipe are fixedly fitted with sealing sleeves. One end of the sealing sleeve is inserted into the inside of the docking groove, and the other end of the sealing sleeve is inserted into the inner wall of the stainless steel pipe.

[0010] As a preferred embodiment, the two ends of the limiting collar are sleeved on the inner and outer walls of the limiting groove, and the middle end of the limiting collar abuts against the outer wall of the connecting pipe.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set stable guide mechanism, the rotating frame is connected to the upright through the rotating groove, so that the rotating frame can rotate flexibly. When installing stainless steel pipes, the angle of the guide stabilizing collar can be quickly adjusted to provide precise guidance for pipe docking, which significantly reduces the installation difficulty. The extension rod can slide inside the rotating frame, and through the cooperation of the sliding block and the sliding groove, the position and spacing of the guide stabilizing collar can be flexibly adjusted to adapt to the horizontal or vertical connection requirements of stainless steel pipes.

[0013] 2. Through the designed connection mechanism and the mating groove design around the connecting pipe, combined with the sealing threaded plug and sealing sleeve, a double sealing system is constructed. The sealing threaded plug can effectively seal the unused mating groove to prevent external impurities from entering the pipeline system. The sealing sleeves at both ends of the connecting pipe are tightly inserted into the mating groove at one end and tightly fitted to the inner wall of the stainless steel pipe at the other end, which greatly avoids liquid or gas leakage at the connection and ensures the sealing performance and operational safety of the pipeline system. The sealing threaded plug allows for easy opening of the mating groove during pipeline maintenance or repair to inspect, clean, or repair the inside of the pipeline. At the same time, the insertion and connection of the connecting pipe and the mating groove allows for easy separation without complicated tools when it is necessary to disassemble part of the pipeline for repair.

[0023] 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.

[0024] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 6 - Appendix Figure 8 A stainless steel pipe connector that is easy to assemble and disassemble includes a connecting mechanism 1 and a stabilizing guide mechanism 2 disposed on its outer side. The stabilizing guide mechanism 2 includes a stabilizing base 201. The stabilizing base 201 is connected to two sets of rotating frames 205 through two sets of rotating grooves 203 on the upright 202. The bottom of each set of rotating frames 205 is provided with a sliding groove 206. Each set of rotating frames 205 is connected to a guide stabilizing collar 209 through an extension rod 207. A limit collar frame 204 is fixedly installed at the upper end of the upright 202.

[0025] The guide stabilizing collar 209, together with the extension rod 207 and the rotating bracket 205, can provide stable support for the pipeline after installation, preventing the pipeline from shaking or displacing due to external forces. This effectively enhances the overall stability and reliability of the pipeline connection and extends the service life of the stainless steel pipeline system.

[0026] The upright 202 is fixedly installed at the center of the upper surface of the stable base 201. Two sets of rotating slots 203 are opened on the outer wall of the upright 202, and two sets of rotating frames 205 are rotatably connected to the inside of the two sets of rotating slots 203 respectively.

[0027] The rotating frame 205 can rotate along the rotating groove 203. There is a certain resistance to the rotation, and it will not rotate under natural conditions, so as to limit the horizontal or vertical pipe.

[0028] The extension rod 207 is slidably connected inside the rotating frame 205. A sliding block 208 is fixedly installed on the lower surface of the extension rod 207 near one end. The sliding block 208 is slidably connected inside the sliding groove 206. The guide and stabilizing collar 209 is fixedly installed on the lower surface of the extension rod 207 near the other end.

[0029] The extension rod 207 can slide and extend within the rotating frame 205, and the sliding block 208 experiences certain resistance while sliding inside the sliding groove 206, and will not slide under normal conditions.

[0030] Specifically, the rotating frame 205 is connected to the upright 202 via the rotating groove 203, allowing the rotating frame 205 to rotate flexibly. When installing stainless steel pipes, the angle of the guide stabilizing collar 209 can be quickly adjusted, providing precise guidance for pipe connection and significantly reducing installation difficulty. The extension rod 207 can slide inside the rotating frame 205 and, through the cooperation of the sliding block 208 and the sliding groove 206, can flexibly adjust the position and spacing of the guide stabilizing collar 209 to meet the horizontal or vertical connection requirements of stainless steel pipes.

[0031] Please see the appendix Figure 1 - Appendix Figure 5 The connecting mechanism 1 includes a connecting pipe 101, and a mating groove 102 is passed through all four sides of the connecting pipe 101. Two sets of mating grooves 102 are internally threaded with sealing thread plugs 104.

[0032] Multiple mating grooves 102 are provided on the connecting pipe 101, two of which can be closed by sealing threaded plugs 104, and the other two are used for inserting mating pipes 105. This design allows the connector to flexibly select the number of connection ports and connection method according to the actual pipeline layout requirements. It can realize the convergence connection of multiple pipelines, and can also close some pipelines when no connection is needed, meeting diverse engineering connection requirements and improving the applicability and flexibility of the connector in different pipeline systems.

[0033] The other two sets of docking grooves 102 are each fitted with a connecting pipe 105. Both ends of the connecting pipe 105 are fixedly fitted with sealing sleeves 106. One end of the sealing sleeve 106 is inserted into the inside of the docking groove 102, and the other end of the sealing sleeve 106 is inserted into the inner wall of the stainless steel pipe. The two ends of the limiting collar 204 are fitted onto the inner and outer walls of the limiting groove 103, and the middle end of the limiting collar 204 abuts against the outer wall of the connecting pipe 101.

[0034] By designing a single connector with multiple connection combinations, the need for multiple connectors due to different connection requirements is reduced. Furthermore, the connecting mechanism 1 and the stable guide mechanism 2 can be connected by a limiting collar 204, ensuring overall integrity while also making disassembly and assembly relatively convenient.

[0035] Specifically, the design of the mating grooves 102 around the connecting pipe 101, together with the sealing threaded plugs 104 and sealing sleeves 106, constructs a double sealing system. The sealing threaded plugs 104 can effectively seal the unused mating grooves 102, preventing external impurities from entering the pipeline system. The sealing sleeves 106 at both ends of the connecting pipe 105 are tightly inserted into the mating grooves 102 at one end and tightly fitted to the inner wall of the stainless steel pipe at the other end, which greatly avoids liquid or gas leakage at the connection and ensures the sealing performance and operational safety of the pipeline system. The setting of the sealing threaded plugs 104 makes it easy to open the mating grooves 102 to inspect, clean or repair the inside of the pipeline when maintaining or repairing the pipeline system. At the same time, the insertion and engagement of the connecting pipe 105 and the mating grooves 102 allows for easy separation without complicated tools when it is necessary to disassemble part of the pipeline for maintenance.

[0036] Working principle of this utility model: This utility model is a stainless steel pipe connector that is easy to assemble and disassemble. The stable base 201 is placed in the predetermined installation position, ensuring its stability. At this time, according to the position and angle of the pipe to be connected, the rotating frame 205 is rotated for initial adjustment. By pulling the extension rod 207, it slides inside the rotating frame 205. Simultaneously, the sliding block 208 on the lower surface of the extension rod 207 slides within the sliding groove 206, thereby precisely adjusting the position and spacing of the guide stabilizing collar 209, according to the pipe connection... If some of the docking slots 102 are not needed, the sealing threaded plug 104 is threaded into the corresponding docking slot 102 to seal it. For docking slots 102 that need to be connected to pipes, the sealing sleeve 106 at one end of the connecting pipe 105 is inserted into the docking slot 102, and the sealing sleeve 106 at the other end is inserted into the inner wall of the stainless steel pipe to complete the initial insertion. The two ends of the limiting collar 204 are respectively fitted onto the outer wall of the limiting groove 103 of the connecting pipe 101, so that the middle end of the limiting collar 204 abuts against the outer wall of the connecting pipe 101. According to the actual disassembly requirements, the position of the extension rod 207 in the rotating frame 205 is adjusted in the opposite direction, so that the guide stabilizing collar 209 is disengaged from the support of the stainless steel pipe. At the same time, the rotating frame 205 is rotated to leave operating space for disassembling the pipe. The connecting pipe 105 is pulled out from the docking slot 102 and the inner wall of the stainless steel pipe. Since the sealing sleeve 106 is inserted into the docking slot 102 and the inner wall of the stainless steel pipe, separation can be easily achieved. If it is necessary to inspect the inside of the connecting pipe 101, the sealing thread plug 104 can be unscrewed, and the relevant operations can be performed through the mating groove 102. The limiting collar 204 can be removed from the limiting groove 103 to complete the overall disassembly of the connector, which is convenient for subsequent maintenance, replacement or transfer to other installation scenarios.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
