[0025] like Figures 1-2 As shown, the integrated grooved clamp quick-connect pipe fitting of this utility model includes a first pipe fitting 1, a second pipe fitting 2, a clamp 3, a sealing element 4, a support plate 5, a connecting plate 6, and a connecting lug 7.

[0026] like Figures 1-2 As shown, both the first pipe fitting 1 and the second pipe fitting 2 have a shell-like structure and are spliced ​​together; the clamp 3 is provided at the ends of both the first pipe fitting 1 and the second pipe fitting 2, and both the first pipe fitting 1 and the second pipe fitting 2 are integrally formed with the clamp 3; the sealing element 4 is partially clamped between the first pipe fitting 1 and the second pipe fitting 2, and is partially located inside the clamp 3; As described above, the first pipe fitting 1 and the second pipe fitting 2 are set as shell-shaped structures and are provided with clamps 3 at the ends. In this way, during assembly, the pipe sections to be connected can be directly clamped by clamps 3 to achieve the connection of the two pipe sections. The inner cavity formed by the spliced ​​first pipe fitting 1 and the second pipe fitting 2 is used to provide a channel for the transportation of fluid media. The first pipe fitting 1 and the second pipe fitting 2 are integrated with the clamp 3, which can ensure the stability of the structure, while reducing the number of required parts and facilitating assembly. Among them, by setting the sealing element 4, it can seal the gap between the first pipe fitting 1 and the second pipe fitting 2, and can also seal the clamp 3 and the pipe section to be connected, thereby ensuring a good sealing effect.

[0027] like Figure 2 As shown, the sealing element 4 includes a sealing ring 41 and a sealing strip 42. There are two sealing rings 41, and the sealing rings 41 are located inside the clamp 3. There are two sealing strips 42, which connect the two sealing rings 41 and are sandwiched between the first pipe fitting 1 and the second pipe fitting 2. As described above, the sealing element 4 is composed of two parts: a sealing ring 41 and a sealing strip 42. The two sealing rings 41 are connected by two sealing strips 42 to form an integral structure. This facilitates the preparation of the sealing element 4 and ensures the stability of the overall structure to guarantee the sealing effect. In practical applications, the first pipe fitting 1 and the second pipe fitting 2 clamp the sealing strip 42 to achieve gap sealing, while the clamp 3 clamps the sealing ring 41 between it and the pipe fitting to be connected to achieve gap sealing.

[0028] like Figure 1 As shown, both the first pipe fitting 1 and the second pipe fitting 2 are provided with protruding ribs 8. The inner side of the protruding ribs 8 of the second pipe fitting 2 and the inner side of the clamp 3 are provided with grooves 100. The sealing element 4 is fitted into the grooves 100. As described above, by opening a groove 100 on the second pipe 2, the sealing strip 42 of the sealing element 4 can be engaged. In this way, the second pipe 2 will have a larger contact area with the sealing strip 42, which achieves the limitation of the sealing strip 42 and ensures the stability of the position of the sealing element 4. Meanwhile, the groove 100 on the clamp 3 is used to engage the sealing ring 41 of the seal 4, thereby ensuring the sealing effect and further guaranteeing the installation stability of the seal 4. Meanwhile, the presence of the convex rib 8 also strengthens the structural strength of the first pipe fitting 1 and the second pipe fitting 2, making their application more stable and reliable.

[0029] like Figure 1 A support plate 5 is provided on the inner side of the groove 100, and the sealing element 4 abuts against the support plate 5; As described above, by providing a support plate 5 inside the groove 100, the position of the seal 4 can be further stabilized.

[0030] Furthermore, both the first pipe fitting 1 and the second pipe fitting 2 are provided with support plates 5, and the support plates 5 on the first pipe fitting 1 and the second pipe fitting 2 are interlocked. As described above, the support plate 5 of the first pipe fitting 1 is inserted into the support plate 5 of the second pipe fitting 2. This allows for the assembly and positioning of the first pipe fitting 1 and the second pipe fitting 2, ensuring good structural stability of the connecting pipe fitting after assembly, thereby ensuring its performance.

[0031] like Figure 1 As shown, both the sealing ring 41 and the sealing strip 42 are provided with strip grooves 401; As described above, by creating a strip groove 401 on the sealing ring 41 and the sealing strip 42, two sealing lips can be formed, which helps to improve the sealing effect.

[0032] Specifically, clamp 3 is cast as an integral structure with the first pipe fitting 1 or the second pipe fitting 2.

[0033] like Figure 1 As shown, the inner side of the second pipe fitting 2 is provided with a protrusion 9, and the first pipe fitting 1 is provided with a groove for inserting the protrusion 9. With the above structure, when the first pipe 1 and the second pipe 2 are spliced, the protrusion 9 on the second pipe 2 can be inserted into the groove of the first pipe 1, thereby ensuring the stable insertion of the first pipe 1 and the second pipe 2 and providing a positioning effect to ensure the stability of the application.

[0034] like Figure 1 As shown, the first pipe fitting 1 and the second pipe fitting 2 have an angular structure; As described above, the first pipe fitting 1 and the second pipe fitting 2 can be set as angular structures, so that when the sealing element 4 is installed, the sealing strip 42 can be set as an arc-shaped structure. Specifically, the angular structure of the first fitting 1 and the second fitting 2 is not limited. It can be set as an acute angle, a right angle or an obtuse angle, or an arc transition can be set at the corner to reduce the resistance to medium flow.

[0035] Specifically, in this application, the shapes of the first pipe fitting 1 and the second pipe fitting 2 are not limited. Setting them as angular structures is only one application example. Specifically, they can be set to various angles such as 11.25°, 22.5°, 45°, and 90°. As needed, this integrated structure can be modified to adapt the angular structure to pipe connection structures such as tees, crosses, and reducers.

[0036] like Figure 1 As shown, one connecting plate 6 is provided on each of the first pipe fitting 1 and the second pipe fitting 2, and the connecting plate 6 is connected to the clamp 3 at the end of the first pipe fitting 1 or the second pipe fitting 2. As described above, by setting the connecting plate 6, the first pipe fitting 1 or the second pipe fitting 2 can be connected to the connecting plate 6, which helps to improve the stability of the overall structure. Meanwhile, during assembly, the connecting plate 6 can be used to install fasteners, such as bolts, thereby bringing the first pipe fitting 1 and the second pipe fitting 2 together.

[0037] like Figure 1 As shown, the connecting ear 7 is set on the clamp 3; As described above, the connecting ear 7 is also used to achieve the connection. After the clamp 3 is connected, the installation bolts can be used to lock and fix it.

[0038] Specific implementation steps: First, insert the pipe section to be connected into the sealing ring 41 of the sealing component 4. Then, connect the first pipe component 1 and the second pipe component 2. The clamp 3 corresponds to the sealing ring 41, and the first pipe component 1 and the second pipe component 2 correspond to the sealing strip 42. Finally, connect the connecting ears 7 on the clamp 3 with bolts, and connect and fix the connecting plate 6.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
