Description

Stainless steel pipe fitting extension edge connection structure Technical Field

[0001] This utility model relates to the field of stainless steel pipe fittings technology, and in particular to the extension edge connection structure of stainless steel pipe fittings. Background Technology

[0002] Stainless steel pipe fittings are widely used in various industrial and civil fields due to their excellent corrosion resistance, high strength, and aesthetic appeal. However, traditional stainless steel pipe fitting connection methods have many drawbacks.

[0003] While common welding connection methods offer high connection strength, they require highly skilled construction workers, are prone to deformation during welding, affecting the overall precision and appearance of the pipe fittings, and may reduce the corrosion resistance of the welded area due to welding process issues. Clamp connections are relatively convenient to install, but their connection strength is limited. Connections using flanges and bolts are more stable, but require workers to tighten multiple bolts, which is time-consuming and labor-intensive, making it difficult to quickly assemble and disassemble multiple pipes. Therefore, we propose a stainless steel pipe fitting extension edge connection structure. Summary of the Invention

[0004] In view of this, this application provides a stainless steel pipe fitting extension edge connection structure, which solves the above technical problems to a certain extent.

[0015] This utility model discloses a stainless steel pipe fitting extension edge connection structure. The elastic buckle is made of high-strength, high-elasticity stainless steel material, which has excellent toughness and fatigue resistance. A groove is set at the corresponding position of the disc, and the shape and size of the groove are precisely matched with the elastic buckle. When the extension fold and expansion fold above the first pipe and the second pipe are connected, simply align the extension fold with the elastic buckle with the expansion fold with the groove, and push gently.

[0024] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Referring to Figures 1-4, the stainless steel pipe fitting extension edge connection structure includes a first pipe 1, an extension flange 2 fixedly installed on one side of the first pipe 1, a second pipe 3 provided on one side of the first pipe 1, an expansion flange 4 fixedly installed on the left side of the second pipe 3, the extension flange 2 and the expansion flange 4 fitting together, two sealing rings 5 ​​fixedly installed on the outer side of the expansion flange 4, a fixing plate 6 fixedly installed on the outer side of the extension flange 2, a disc 8 fixedly installed on the outer side of the expansion flange 4, multiple elastic buckles 7 fixedly installed on the right side of the fixing plate 6, and multiple slots 9 opened on one side of the disc 8, with the elastic buckles 7 corresponding to the slots 9.

[0027] In a further preferred embodiment of the present invention, a plurality of limiting grooves 10 are provided on the right side of the disc 8, a slider 11 is slidably installed on the inner side of the limiting groove 10, and a pressing control block 12 is fixedly installed on one side of the slider 11.

[0028] In a further preferred embodiment of this utility model, the pressing control block 12 is semi-circular in shape, and the two pressing control blocks 12 are arranged opposite to each other; the semi-circular pressing control block 12 allows the operator to operate with one hand when pressing, making it easier to detach the first pipe 1 and the second pipe 3.

[0029] In a further preferred embodiment of this utility model, the extended fold 2 and the extended fold 4 are both arc-shaped, and the first pipe 1, the extended fold 2, the second pipe 3 and the extended fold 4 are all made of stainless steel. The stainless steel first pipe 1, extended fold 2, second pipe 3 and extended fold 4 are less prone to corrosion and rust during long-term use, which can improve the service life of the pipe. The arc-shaped extended fold 2 and extended fold 4 can increase the connection area of ​​the pipe.

[0030] In a further preferred embodiment of this utility model, an annular groove is provided on the left side of the extended folded edge 4, and the sealing ring 5 is fixedly installed on the inner side of the annular groove; the annular groove facilitates the installation and fixing of the sealing ring 5, allowing the sealing ring 5 to fit tightly with the extended folded edge 4. After the extended folded edge 2 is connected to the extended folded edge 4, the connection gap between the extended folded edge 2 and the extended folded edge 4 can be sealed, making the connection between the first pipe 1 and the second pipe 3 on both sides relatively tight.

[0031] In a further preferred embodiment of this utility model, the elastic buckle 7 is made of elastic steel, and a triangular locking block is provided on one side of the elastic buckle 7. When it is necessary to disassemble the pipe connection, simply press the pressing control block 12 lightly. After pressing, the pressing control block 12 can slide through the cooperation of the limiting slide groove 10 and the slider 11, which can squeeze the elastic buckle 7, causing the elastic buckle 7 to change shape and thus detach from the inside of the slot 9, thereby realizing the quick disassembly of the pipe.

[0032] In a further preferred embodiment of this utility model, the sealing ring 5 is made of rubber, and the sealing ring 5 matches the contact surfaces of the extended fold 2 and the extended fold 4; the sealing ring 5 is provided between the contact surfaces of the extended fold 2 and the extended fold 4, and the sealing ring 5 is made of corrosion-resistant and aging-resistant rubber material, and its shape matches the shape of the contact surfaces of the extended fold 2 and the extended fold 4; it can effectively fill the tiny gaps between the extended fold 2 and the extended fold 4 to prevent media leakage.

[0033] In a further preferred embodiment of this utility model, the slider 11 is T-shaped and fits into the limiting groove 10; multiple limiting grooves 10 are provided above the disc 9, and the slider 11 is provided on the inner side of the limiting groove 10. The slider 11 can only slide on the inner side of the limiting groove 10; this ensures that the slider 11 and the pressing control block 12 will not detach from the inner side of the limiting groove 10.

[0034] Specifically, the extended flange 2 and extended flange 4 above the first pipe 1 and the second pipe 3 adopt a unique arc-shaped flange structure. Compared with the traditional straight edge design, the arc-shaped flange significantly increases the contact area between the ends of the pipe fittings. This larger contact area not only improves the stability of the connection, but also distributes external forces more evenly, effectively enhancing the tensile and shear resistance of the connection part.

[0035] The elastic buckle 7 is made of high-strength, high-elasticity stainless steel, which has excellent toughness and fatigue resistance. A slot 9 is set at the corresponding position of the disc 8. The shape and size of the slot 9 are precisely matched with the elastic buckle 7. When the extended fold 2 and the extended fold 4 above the first pipe 1 and the second pipe 3 are connected, simply align the extended fold 2 with the elastic buckle 7 with the extended fold 4 with the slot 9, and push gently. The elastic buckle 7 will undergo elastic deformation when squeezed and smoothly snap into the slot 9, achieving a quick and firm connection.

[0036] A sealing ring 5 is provided between the contact surfaces of the extended fold 2 and the extended fold 4. The sealing ring 5 is made of corrosion-resistant and aging-resistant rubber material, and its shape matches the contact surface shape of the extended fold 2 and the extended fold 4. It can effectively fill the tiny gap between the extended fold 2 and the extended fold 4 to prevent media leakage.

[0037] Multiple limiting grooves 10 are provided above the disc 9. A slider 11 is provided on the inner side of the limiting groove 10. The slider 11 can only slide on the inner side of the limiting groove 10. When it is necessary to disassemble the pipe connection, simply press the pressing control block 12. After pressing, the pressing control block 12 can slide through the cooperation of the limiting groove 10 and the slider 11, which can squeeze the elastic buckle 7, causing the elastic buckle 7 to change shape and thus disengage from the inner side of the groove 9, realizing the quick disassembly of the pipe. This design makes the disassembly process simple and convenient, and greatly improves the efficiency of maintenance and repair.

[0038] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
