[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. Furthermore, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in manufacturing mechanical parts and engineering structures. High-temperature resistant stainless steel pipe is also a type of stainless steel pipe. Traditionally, high-temperature resistant stainless steel pipes are mostly fixed by multiple sets of bolts, which makes the fixing process extremely cumbersome and requires appropriate installation tools. This makes it difficult to quickly connect high-temperature resistant stainless steel pipes, and the stability of the connection cannot be guaranteed, easily leading to breakage at the joint and posing a significant safety hazard.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0005] The technical solution of this utility model is implemented as follows: a high-temperature resistant stainless steel pipe includes two sets of high-temperature resistant stainless steel pipe bodies symmetrically arranged in the left-right direction. A docking ring is fixed at one end of the high-temperature resistant stainless steel pipe bodies that are close to each other. A reinforcing pipe is inserted at one end of the high-temperature resistant stainless steel pipe bodies that are close to each other. A positioning ring is fixed at the middle section of the reinforcing pipe. The docking rings are attached to the positioning ring on one side that is close to each other. A self-locking component that cooperates with the docking ring is provided on the positioning ring.

[0006] The present invention provides a high-temperature resistant stainless steel pipe as described above, further comprising: the self-locking assembly including arc-shaped brackets symmetrically engaged with the front and back sides of the docking ring and the positioning ring along the front-back direction; each set of arc-shaped brackets has an L-shaped bracket fixed at the top and bottom; adjacent sets of L-shaped brackets have positioning seats engaged with each other; a support plate is fixed on the left side of the positioning seat; an L-shaped connector is inserted into the support plate; a square sleeve for inserting the bottom ends of the L-shaped connector is fixed at the top and bottom of the left side of each set of arc-shaped brackets; multiple sets of springs are fixed on the left side of the positioning seats on the opposite side; one end of each spring is fixed to the bent end of the L-shaped connector.

[0007] The present invention provides a high-temperature resistant stainless steel pipe as described above, further comprising: multiple sets of anti-displacement rods uniformly fixed on both sides of the positioning ring, and each set of the docking ring having a fixed insertion hole for inserting one end of the anti-displacement rod.

[0008] The present invention provides a high-temperature resistant stainless steel pipe as described above, further comprising: positioning plates fixed on both the front and back of the positioning ring; and auxiliary slots for inserting the positioning plates are provided on the opposite side of the arc-shaped card seat.

[0009] The present invention provides a high-temperature resistant stainless steel pipe as described above, further comprising: two adjacent sets of L-shaped clamps arranged in opposite directions, and the two adjacent sets of L-shaped clamps forming an overall T-shaped structure.

Detailed Implementation

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0027] A high-temperature resistant stainless steel pipe includes two sets of high-temperature resistant stainless steel pipe bodies 1 symmetrically arranged in the left-right direction. A connecting ring 2 is fixed to one end of each high-temperature resistant stainless steel pipe body 1 that is close to the other. A reinforcing pipe 3 is inserted into one end of each high-temperature resistant stainless steel pipe body 1 that is close to the other. A positioning ring 4 is fixed to the middle section of the reinforcing pipe 3. The connecting ring 2 is attached to the positioning ring 4 on one side that is close to the other. A self-locking component is provided on the positioning ring 4 to cooperate with the connecting ring 2. The self-locking component includes components that are symmetrically engaged with the connecting ring 2 and the positioning ring 4 in the front-back direction. The front and back of the arc-shaped card holder 7 are each fixed with an L-shaped card plate 10 at the top and bottom. A positioning seat 15 is snapped onto two adjacent sets of L-shaped card plates 10. A support plate 13 is fixed on the left side of the positioning seat 15. An L-shaped plug-in bracket 11 is inserted into the support plate 13. A square sleeve 14 for inserting the bottom ends of the L-shaped plug-in bracket 11 is fixed at the top and bottom of the left side of each set of arc-shaped card holder 7. Multiple sets of springs 12 are fixed on the left side of the positioning seat 15 on the side that is far apart from each other. One end of the spring 12 is fixed to the bent end of the L-shaped plug-in bracket 11.

[0028] Specifically, this utility model, by setting a self-locking component, utilizes spring 12, L-shaped plug-in bracket 11, and square sleeve 14 to form a quick-locking structure for positioning seat 15, so that positioning seat 15 can be used to quickly fix two adjacent sets of L-shaped clamping plates 10, thereby quickly fixing arc-shaped clamping seat 7, and then quickly docking and positioning two sets of high-temperature resistant stainless steel pipe bodies 1. In conjunction with the reinforcement pipe 3, it effectively supports the docking point between the two sets of high-temperature resistant stainless steel pipe bodies 1, so that while ensuring docking stability, the two sets of high-temperature resistant stainless steel pipe bodies 1 can be quickly docked and fixed by a snap-fit ​​docking method, improving docking efficiency and reinforcing the docking point between the two sets of high-temperature resistant stainless steel pipe bodies 1.

[0029] The positioning ring 4 has multiple sets of anti-slip rods 6 evenly fixed on both sides in a ring shape. Each set of docking rings 2 has a fixed insertion hole 5 for inserting one end of the anti-slip rod 6.

[0030] Specifically, by using the anti-slip rod 6 and the fixing hole 5, the two sets of high-temperature resistant stainless steel pipe bodies 1 can be pre-positioned and connected, which improves the stability of the two sets of high-temperature resistant stainless steel pipe bodies 1 when they are connected, and prevents the high-temperature resistant stainless steel pipe bodies 1 from easily rotating relative to each other under the influence of external forces after connection.

[0031] Positioning plates 8 are fixed on both the front and back of the positioning ring 4, and auxiliary slots 9 for the positioning plates 8 are provided on the opposite side of the arc-shaped card seat 7 for insertion.

[0032] Specifically, the positioning plate 8 and the auxiliary slot 9 are used to position the arc-shaped card seat 7, so as to assist the two sets of arc-shaped positioning seats 15 to quickly dock, which improves the assembly efficiency and prevents the arc-shaped card seat 7 from rotating easily after docking, further improving the docking stability.

[0033] The two adjacent sets of L-shaped card plates 10 are arranged in opposite directions, and the two adjacent sets of L-shaped card plates 10 form a T-shaped structure.

[0034] Specifically, the two sets of L-shaped clamping plates 10 arranged in opposite directions, together with the L-shaped clamping plates 10 with an overall T-shaped structure, make the positioning seat 15 more securely engaged with the two adjacent sets of L-shaped clamping plates 10, thereby improving the docking stability of the two sets of arc-shaped clamping seats 7.

[0035] The number of springs 12 on each L-shaped connector 11 is at least two.

[0036] Specifically, the number of springs 12 is limited to provide sufficient tensile force to the L-shaped connector 11, thereby effectively preventing the L-shaped connector 11 from easily detaching from the square sleeve 14, and thus effectively locking and positioning the positioning seat 15, improving the docking stability of the two sets of arc-shaped card seats 7.

[0037] The number of positioning rings 4 and anti-displacement inserts 6 on one side is at least seven.

[0038] Specifically, limiting the number of anti-displacement inserts 6 on one side of the positioning ring 4 effectively improves the stability between the positioning ring 4 and the docking ring 2, thereby improving the stability between the high-temperature resistant stainless steel pipe body 1 and the reinforced pipe 3. The specific usage process is as follows: When two sets of high-temperature resistant stainless steel pipe bodies 1 need to be docked, the user inserts one end of the reinforced pipe 3 into one set of high-temperature resistant stainless steel pipe bodies 1, and makes the left side of the positioning ring 4 contact the docking ring 2 on that set of high-temperature resistant stainless steel pipe bodies 1. The anti-displacement insert 6 on the left side of the positioning ring 4 will be inserted into the fixing hole 5 on the docking ring 2. Then, the user inserts the other set of high-temperature resistant stainless steel pipe bodies 1 into the other end of the reinforced pipe 3 until the docking ring 2 contacts the right side of the positioning ring 4, and the right anti-displacement insert 6 is inserted into the fixing hole 5 on the other set of docking rings 2. Then, the user connects the two sets of arc-shaped... The card holder 7 is engaged with the docking ring 2 and the positioning ring 4, and the two adjacent sets of L-shaped card plates 10 are in contact. At this time, the positioning plate 8 is inserted into the auxiliary card slot 9. Then, the user pulls up the L-shaped plug-in bracket 11 and stretches the spring 12, while simultaneously engaging the positioning seat 15 with the L-shaped card plate 10, until the bottom two ends of the L-shaped plug-in bracket 11 are moved above the square sleeve 14. At this time, the elastic rebound of the spring 12 can drive the L-shaped plug-in bracket 11 to move down and insert its bottom end into the square sleeve 14, locking the positioning seat 15. Thus, the positioning seat 15 can be used to quickly fix the two sets of arc-shaped card holders 7, and then the two sets of high-temperature resistant stainless steel pipe bodies 1 can be quickly docked and fixed. Furthermore, the reinforcement pipe 3 effectively supports the joint between the two sets of high-temperature resistant stainless steel pipe bodies 1. While ensuring joint stability, a snap-fit ​​joint method is used to quickly and securely connect and fix the two sets of high-temperature resistant stainless steel pipe bodies 1, improving connection efficiency. It also reinforces the joint between the two sets of high-temperature resistant stainless steel pipe bodies 1, preventing breakage and avoiding safety hazards. This utility model, by setting a self-locking component, utilizes spring 12, L-shaped plug-in bracket 11, and square sleeve 14 to form a quick-locking structure for the positioning seat 15. This allows the positioning seat 15 to quickly fix two adjacent sets of L-shaped clamping plates 10, thereby quickly fixing the arc-shaped clamping seat 7, and further... The high-temperature resistant stainless steel pipe body 1 is quickly connected and positioned, and the reinforcement pipe 3 effectively supports the connection between the two sets of high-temperature resistant stainless steel pipe bodies 1. This allows for quick connection and fixation of the two sets of high-temperature resistant stainless steel pipe bodies 1 by a snap-fit ​​connection method while ensuring connection stability. This improves connection efficiency and strengthens the connection between the two sets of high-temperature resistant stainless steel pipe bodies 1. By using the anti-slip plug 6 and the fixing plug hole 5, the two sets of high-temperature resistant stainless steel pipe bodies 1 can be pre-connected and positioned, improving the stability of the two sets of high-temperature resistant stainless steel pipe bodies 1 during connection and preventing the high-temperature resistant stainless steel pipe bodies 1 from easily rotating under the influence of external forces after connection.By utilizing the snap-fit ​​of the positioning plate 8 and the auxiliary slot 9, the arc-shaped card seat 7 can be positioned to facilitate the rapid docking of the two sets of arc-shaped positioning seats 15, improving assembly efficiency and preventing the arc-shaped card seat 7 from easily rotating after docking, further enhancing docking stability. The two sets of L-shaped card plates 10 arranged in opposite directions, along with the overall T-shaped L-shaped card plate 10, allow the positioning seat 15 to be more securely engaged with the adjacent two sets of L-shaped card plates 10, improving the docking stability of the two sets of arc-shaped card seats 7. Limiting the number of springs 12 provides sufficient tensile force to the L-shaped plug-in bracket 11, effectively preventing the L-shaped plug-in bracket 11 from easily detaching from the square sleeve 14, thus effectively locking and positioning the positioning seat 15, improving the docking stability of the two sets of arc-shaped card seats 7. Limiting the number of anti-shifting plug rods 6 on one side of the positioning ring 4 effectively improves the stability between the positioning ring 4 and the docking ring 2, thereby improving the stability between the high-temperature resistant stainless steel pipe body 1 and the reinforced pipe 3.
