A new type of spliced ​​stainless steel pipe

Abstract

This utility model relates to the field of stainless steel pipe technology and discloses a novel spliced ​​stainless steel pipe, including a stainless steel pipe 1, with a connector threaded onto the outer wall of the stainless steel pipe 1. This utility model involves threading a connector and a second connector onto the surfaces of stainless steel pipe 1 and stainless steel pipe 2 respectively. A limiting block is then aligned with a clearance groove on the surface of the second connector. The stainless steel pipe 1 is then moved to drive the connector, which in turn moves the limiting block into the clearance groove. Rotating the stainless steel pipe 1 causes the connector to rotate, and the connector rotates the limiting block into the limiting groove, thus completing the connection. Simultaneously, the connector causes a sealing ring to press against the surface of the second connector, thereby sealing the liquid flowing inside the stainless steel pipes 1 and 2 and isolating external harmful substances and rainwater. This connection method is simple and convenient.

Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, and in particular to a novel spliced ​​stainless steel pipe. Background Technology

[0002] Stainless steel pipe fittings are a general term for various stainless steel pipe connection components. They are made of stainless steel and can be classified into different categories according to shape, use, and connection method. They have chemical resistance, resistance to alkali metals and acids, high toughness, and flame retardancy. Stainless steel pipe is a type of cross-sectional steel material that is widely used in domestic decoration and industry. Because stainless steel pipe has a hollow cross-section, it is most suitable for use as a pipeline for transporting liquids, gases, and solids.

[0003] In the existing technology, most stainless steel pipe splicing devices use threads and bolts to splice stainless steel pipes together. During long-term use, stainless steel pipes with this connection method are prone to problems such as rusting and aging of bolts due to rain and high temperature. As a result, during subsequent disassembly, the aged bolts are likely to break off inside the stainless steel pipe, making the stainless steel pipe unusable. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel splicing stainless steel pipe.

[0005] This utility model is achieved using the following technical solution: A novel spliced ​​stainless steel pipe includes a stainless steel pipe one, a connector threaded to the outer wall of the stainless steel pipe one, a sealing ring disposed on the left side of the connector, a limit block fixedly connected to the left side of the connector, a sealing ring two disposed at the end of the sealing ring away from the connector, a connector two disposed at the end of the sealing ring two away from the sealing ring, a stainless steel pipe two threaded to the inner wall of the connector two, an clearance groove formed on the surface of the stainless steel pipe two, a limit groove formed on the surface of the stainless steel pipe two, and the outer wall of the limit block slidably connected to the clearance groove.

[0006] As a further improvement to the above solution, the sealing ring is disposed on the outer wall of the limiting block, and the outer wall of the limiting block is slidably connected to the inner wall of the limiting groove.

[0007] As a further improvement to the above solution, four limiting blocks are provided, four clearance slots are provided, and four limiting slots are provided.

[0008] Through the above technical solution, the connector head and connector head 2 are threaded onto the surfaces of stainless steel pipe 1 and stainless steel pipe 2 respectively. Then, the limiting block is aligned with the clearance groove opened on the surface of connector head 2. Then, stainless steel pipe 1 drives the connector head, and the connector head drives the limiting block to slide into the clearance groove. Then, stainless steel pipe 1 is rotated.

[0009] As a further improvement to the above solution, a limiting head is threadedly connected to the outer wall of the connector, and the limiting head is slidably connected to the outer wall of the stainless steel pipe.

[0010] As a further improvement to the above solution, a second limiting groove is formed on the surface of the limiting head, a rotating shaft is rotatably connected to the inner wall of the second limiting groove, and a third limiting groove is formed on the surface of the second connecting head.

[0011] As a further improvement to the above solution, the outer wall of the rotating shaft is in contact with the surface of the second connector, and a limiting rod is fixedly connected to one end of the rotating shaft near the second connector. The outer wall of the limiting rod is slidably connected to the inner wall of the third limiting groove, and the outer wall of the limiting rod is slidably connected to the surface of the limiting block.

[0012] As a further improvement to the above solution, the limiting groove is provided with four openings, and the limiting rod is provided with four openings.

[0013] With the above technical solution, when the limiting block is connected inside the limiting groove, the limiting rod can be aligned with the limiting groove three opened on the surface of the second connector, and then the limiting head can be threaded onto the surface of the second connector. As the limiting head rotates, the limiting rod drives the rotating shaft to rotate on the inner wall of the limiting groove two opened on the limiting head.

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

[0015] This invention connects a connector and a second connector to the surfaces of stainless steel pipes 1 and 2 respectively via threaded connections. A limiting block is then aligned with a clearance groove on the surface of the second connector. The stainless steel pipe 1 moves the connector, which in turn moves the limiting block into the clearance groove. Rotating the stainless steel pipe 1 causes the connector to rotate, and the connector rotates the limiting block into the clearance groove, thus completing the connection. Simultaneously, the connector causes a sealing ring to press against the surface of the second sealing ring on the second connector, sealing the liquid flowing inside the stainless steel pipes 1 and 2. This also isolates external harmful substances and rainwater. This connection method is simple and convenient, preventing drawbacks such as bolts breaking off inside the stainless steel pipes due to aging.

[0016] This invention allows for the following: When the limiting block is connected inside the limiting groove, the limiting rod is aligned with the limiting groove three opened on the surface of the connecting head two. Then, the limiting head is threaded onto the surface of the connecting head two. As the limiting head rotates, the limiting rod drives the rotating shaft to rotate on the inner wall of the limiting groove two opened on the limiting head. This causes the limiting rod to slide along the limiting groove three towards the surface of the limiting block, thereby limiting the limiting block and preventing it from dislodging from the limiting groove due to vibration or other factors. This design is particularly suitable for scenarios involving rapid repairs and frequent disassembly. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-6 This embodiment of a novel splicing stainless steel pipe includes a stainless steel pipe 1, a connector 2 threadedly connected to the outer wall of the stainless steel pipe 1, a sealing ring 3 disposed on the left side of the connector 2, a limiting block 4 fixedly connected to the left side of the connector 2, a second sealing ring 5 disposed on the end of the sealing ring 3 away from the connector 2, a second connector 6 disposed on the end of the second sealing ring 5 away from the sealing ring 3, a stainless steel pipe 7 threadedly connected to the inner wall of the second connector 6, a clearance groove 8 and a limiting groove 9 formed on the surface of the second stainless steel pipe 7, and the outer wall of the limiting block 4 slidably connected to the clearance groove 8.

[0028] The sealing ring 3 is positioned on the outer wall of the limiting block 4, and the outer wall of the limiting block 4 is slidably connected to the inner wall of the limiting groove 9.

[0029] There are four limit blocks 4, four clearance slots 8, and four limit slots 9.

[0030] Connector 26 has a threaded connection to a limiting head 10 on its outer wall, and the limiting head 10 is slidably connected to the outer wall of stainless steel pipe 27.

[0031] Limiting head 10 has a second limiting groove 11 on its surface, and a rotating shaft 13 is rotatably connected to the inner wall of the second limiting groove 11. Connecting head 2 6 has a third limiting groove 12 on its surface.

[0032] The outer wall of the rotating shaft 13 is in contact with the surface of the connector 6. The end of the rotating shaft 13 near the connector 6 is fixedly connected to a limiting rod 14. The outer wall of the limiting rod 14 is slidably connected to the inner wall of the limiting groove 12. The outer wall of the limiting rod 14 is slidably connected to the surface of the limiting block 4.

[0033] There are four limit grooves 12 and four limit rods 14.

[0034] The implementation principle of a novel splicing stainless steel pipe in this application embodiment is as follows: by threading connector 2 and connector 6 onto the surfaces of stainless steel pipe 1 and stainless steel pipe 7 respectively, then aligning the limiting block 4 with the clearance groove 8 opened on the surface of connector 6, then moving stainless steel pipe 1 to drive connector 2, connector 2 to drive limiting block 4 to slide into clearance groove 8, and then rotating stainless steel pipe 1, stainless steel pipe 1 to rotate connector 2, connector 2 to rotate limiting block 4 into limiting groove 9, thereby completing the connection between the two.

[0035] At the same time, the connector 2 drives the sealing ring 3 to fit and press against the sealing ring 5 on the surface of the connector 2 6, so that the sealing ring 3 and the sealing ring 2 5 seal the liquid flowing inside the stainless steel pipe 1 and stainless steel pipe 2 7, and can also isolate external harmful substances and rainwater. This connection method is simple and convenient, and prevents the disadvantages such as bolts breaking inside the stainless steel pipe 1 and stainless steel pipe 2 7 due to aging.

[0036] When the limiting block 4 is connected inside the limiting groove 9, the limiting rod 14 can be aligned with the limiting groove 12 opened on the surface of the connecting head 2 6, and then the limiting head 10 can be threaded onto the surface of the connecting head 2 6. As the limiting head 10 rotates, the limiting rod 14 drives the rotating shaft 13 to rotate on the inner wall of the limiting groove 2 11 opened on the limiting head 10. This causes the limiting rod 14 to slide along the limiting groove 3 12 toward the surface of the limiting block 4, thereby limiting the limiting block 4 by the limiting rod 14 and preventing the limiting block 4 from falling out of the limiting groove 9 due to vibration or other factors. This design is particularly suitable for scenarios involving rapid repair and frequent disassembly.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
