Description

Technical Field

[0001] This utility model relates to stainless steel pipes, and more particularly to a stainless steel pipe with a joint. Background Technology

[0002] Stainless steel pipe is a type of pipe made of stainless steel. It has good corrosion resistance, heat resistance and high mechanical strength, so it is widely used in many fields, such as chemical, petroleum, pharmaceutical, food, light industry, shipbuilding, water treatment and machinery equipment industries.

[0003] Due to limitations in manufacturing processes, seamless stainless steel pipes are typically shorter in length, and manufacturing large-diameter products is even more challenging. This poses a challenge to the design of long-distance pipelines. On the other hand, stainless steel pipes without joints lack flexibility during installation. Compared to pipeline systems with joints, they are not easily disassembled, replaced, or expanded once formed. This causes inconvenience in projects requiring frequent maintenance or complex layouts. Especially in applications with limited space or requiring multi-directional branching, the lack of joint design significantly increases construction difficulty. Therefore, by setting joints on steel pipes, it is possible to facilitate connections with other steel pipes.

[0004] Therefore, how to make the joints on the steel pipe detachable to facilitate multi-branch layout scenarios has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stainless steel pipe with a joint, which connects the second steel pipe to the joint located on the first steel pipe by inserting the second steel pipe into the joint.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a first steel pipe and a connector, wherein the first steel pipe extends axially to the left and right and the connector is located on the left side of the first steel pipe, the inner wall of the first steel pipe is hollow, and further including a second steel pipe connected to the connector, wherein the first steel pipe and the second steel pipe have the same shape and size, and the first steel pipe and the second steel pipe are detachably connected to the left and right sides of the connector respectively.

[0007] The present invention is further configured such that: the first steel pipe includes a connecting section with an inserted connector, the connector is provided with a connecting groove corresponding to the connecting section, and the connecting section is provided with a plurality of positioning protrusions at intervals around the circumference to prevent the connecting section from rotating relative to the connector; a positioning seat made of rubber is fixedly installed on the right side of the first steel pipe at the connector, and the positioning seat is used to insert the connector.

[0008] The present invention is further configured such that: the connector is provided with a positioning groove corresponding to each positioning protrusion, and the connector is located on the right side of each positioning groove and is open.

[0009] The present invention is further configured such that each of the positioning protrusions includes a left-side inclined surface, and the inclined surface is inclined from left to right and from bottom to top.

[0010] The present invention is further configured such that: the connector is provided with mating blocks between each positioning groove, and each mating block is inserted between adjacent positioning protrusions.

[0011] The present invention is further configured such that: the positioning seat includes a limiting section for sleeved connector, and a limiting ring is provided protruding inward in the middle of the connecting section, and the limiting ring is inserted into the connecting section.

[0012] The present invention is further configured such that: the cross-section of the limiting ring is triangular and includes an inner guide surface that is inclined from left to right and radially from outside to inside.

[0013] The present invention is further provided with a sealing ring located between the connecting section and the joint.

[0014] By adopting the above technical solution, when the first steel pipe and the second steel pipe are connected together, the overall length can be increased to achieve the connection length of the entire stainless steel pipe, meeting more usage requirements. Since the first steel pipe and the second steel pipe have the same shape and size, if the first steel pipe or the second steel pipe is worn during the assembly process, it can be replaced because the first steel pipe and the second steel pipe are exactly the same, thus providing convenience for production and installation. Furthermore, since the joint is detachably connected to the first steel pipe and the second steel pipe, when the first steel pipe or the second steel pipe is worn, a new steel pipe can be replaced by separating the joint and the worn steel pipe, thereby extending the service life of the other steel pipe and the joint.

[0028] 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.

[0029] like Figures 1-8As shown, this utility model discloses a stainless steel pipe with a connector 2, including a first steel pipe 1 and a connector 2. The first steel pipe 1 extends axially to the left and right, and the connector 2 is located on the left side of the first steel pipe 1. The inner wall of the first steel pipe 1 is hollow, and fluid flows through the first steel pipe 1. By connecting other steel pipes to the connector 2, multiple steel pipes can be assembled. It also includes a second steel pipe 3 connected to the connector 2. The first steel pipe 1 and the second steel pipe 3 have the same shape and size. The first steel pipe 1 and the second steel pipe 3 are detachably connected to the left and right sides of the connector 2, respectively. When the first steel pipe 1 and the second steel pipe 3 are connected together... This increases the overall length of the stainless steel pipe, meeting more usage needs. Since the first steel pipe 1 and the second steel pipe 3 have the same shape and size, if the first steel pipe 1 or the second steel pipe 3 is worn during assembly, it can be replaced because the first steel pipe 1 and the second steel pipe 3 are exactly the same. This provides convenience for production and installation. Furthermore, since the joint 2 is detachably connected to the first steel pipe 1 and the second steel pipe 3, when the first steel pipe 1 or the second steel pipe 3 is worn, the joint 2 and the worn steel pipe can be separated and replaced with a new steel pipe, thereby extending the service life of the other steel pipe and the joint 2.

[0030] The first steel pipe 1 includes a connecting section 11 for inserting a connector 2. The connector 2 is provided with a connecting groove 21 corresponding to the connecting section 11. The connecting section 11 is provided with a plurality of positioning protrusions 111 at circumferential intervals to prevent the connecting section 11 from rotating relative to the connector 2. The first steel pipe 1 is fixedly installed with a positioning seat 12 made of rubber on the right side of the connector 2. The positioning seat 12 inserts the connector 2. When the connecting section 11 of the first steel pipe 1 is inserted into the connector 2, the positioning protrusions 111 will cooperate with the connector 2, thus preventing the connecting section 11 from rotating radially relative to the connector 2. Since the first steel pipe 1 is fixedly installed with the positioning seat 12 on the right side of the connector 2, and the positioning seat 12 can insert the connector 2, a force is applied to the positioning seat 12, so that after the connector 2 is inserted, the first steel pipe 1 cannot move axially relative to the connector 2, thereby achieving a stable connection between the connector 2 and the first steel pipe 1.

[0031] The connector 2 is provided with a positioning groove 22 corresponding to each positioning protrusion 111. The connector 2 is located on the right side of each positioning groove 22 and is open. Since the connector 2 is located on the right side of each positioning groove 22 and is open, when the connecting section 11 of the first steel pipe 1 is inserted into the connector 2, each positioning protrusion 111 of the connecting section 11 can be directly inserted into the corresponding positioning groove 22 through the opening on the right side of each positioning groove 22, thus facilitating the determination of the relative position of the connecting section 11 of the first steel pipe 1 and the connector 2.

[0032] Preferably, each of the positioning protrusions 111 includes a left-side inclined surface 1111, and the inclined surface 1111 is inclined from left to right and from bottom to top. Therefore, when the connecting section 11 is inserted into the connector 2, the left-side inclined surface 1111 of each positioning protrusion 111 will first enter into each positioning groove 22, thereby facilitating the alignment of each positioning protrusion 111 with one end of the corresponding positioning groove 22, making the insertion smoother.

[0033] The connector 2 is provided with mating blocks 23 between each positioning groove 22. Each mating block 23 is inserted between adjacent positioning protrusions 111. When the connecting section 11 is installed into the connector 2, as each positioning protrusion 111 enters the corresponding positioning groove 22, the mating blocks 23 of the connector 2 between each positioning groove 22 will fall into the adjacent positioning protrusions 111, thereby making the relative position of the connector 2 and the connecting section 11 more stable, that is, the connector 2 cannot be radially connected to the connecting section 11.

[0034] The positioning seat 12 includes a limiting section 121 for fitting the connector 2. A limiting ring 1211 protrudes inward from the middle of the limiting section 121. The limiting ring 1211 is inserted into the connector 2 and performs axial limiting function to prevent the positioning seat 12 on the first steel pipe 1 from separating from the connector 2. It is also worth noting that due to the setting of the limiting ring 1211, after the connector 2 is connected to the positioning seat 12 and the connecting section 11, if the fluid in the first steel pipe 1 leaks at the connection position of the connector 2 and the connecting section 11, it will reach the limiting section 121 and be affected by the limiting section 121, thus preventing it from passing through the limiting section 121 and improving the sealing effect between the two.

[0035] The limiting ring 1211 has a triangular cross-section and includes an inner guide surface 12111 that is inclined from left to right and radially from outside to inside. Since the guide surface 12111 is inclined, when the positioning seat 12 is subjected to a force to bend the limiting segment 121 outward, the innermost side of the limiting ring 1211 will first enter the connector 2, thus facilitating the insertion of the limiting ring 1211 into the connector 2.

[0036] Preferably, a sealing ring 4 is provided between the connecting section 11 and the connector 2. The sealing ring 4 effectively prevents fluid leakage from the connection and improves the sealing performance of the entire stainless steel pipe connection.

[0037] It also includes a socket 122 on the positioning seat 12 and a screw hole 24 on the connector 2 corresponding to the socket 122. A bolt that is compatible with the screw hole 24 is inserted into the socket 122 and threaded into the screw hole 24 (not shown in the bolt diagram). This can improve the connection strength between the connector 2 and the first steel pipe 1.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
