[0032] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0033] Please refer to Figures 1-3 .like Figures 1-3 As shown, on the one hand, the present invention provides a clamp with a ribbed inner liner, the clamp including a clamp band 1, a clamp shell assembly 2, a screw 4 and a clamp band inner liner 5;
[0034] The clamp 1 includes a fixed end 11 and an adjusting end 12. The surface of the adjusting end 12 is provided with an adjusting hole 13 along the length direction that matches the thread on the screw 4.
[0035] The hoop assembly 2 includes a hoop seat 21 and a hoop 22. The hoop seat 21 is fixedly connected to the inner wall of the fixed end 11. The hoop 22 is provided with a receiving groove along the axial direction. The receiving groove is located on the side of the hoop 22 close to the hoop seat 21. The screw 4 is sleeved into the receiving groove of the hoop 22. The hoop 22 is placed on the side of the hoop band 1 away from the hoop seat 21 and is fixedly connected to the hoop seat 21.
[0036] The adjusting end 12 of the hoop 1 is configured to extend into the receiving groove and move by rotating the screw 4 to adjust the hoop diameter. The adjusting end 12 is located between the fixed end 11 and the screw 4.
[0037] The inner liner 5 is fitted onto the inner wall of the hoop 1 rolled into a ring. The inner surface of the inner liner 5 is provided with at least two protruding ribs 51 along the length direction. The inner side of the inner liner 5 is provided with a limiting edge 52 facing one side of the hoop 1 along the radial direction. The limiting edge 52 is limited to the side of the hoop 1.
[0038] The design of reinforced double inner ribs enhances the overall sealing performance of the clamp.
[0039] This patented double-ribbed liner clamp, by adding a reinforced double-ribbed liner, features two sealing lines, enhancing the overall sealing performance of the clamp. The sealing method is changed to two-line-surface contact, unlike the traditional surface-to-surface contact. Long-term research and experimentation have shown that surface-to-surface contact sealing performance is relatively average, while the improved line-surface contact significantly improves the clamp's sealing performance and reduces leakage in the pipeline. Simultaneously, the double-ribbed liner also provides a certain degree of compensating for clamping force.
[0040] In the example, the adjusting end 12 of the clamp 1 extends into the receiving groove. Rotating the screw causes the adjusting end 12 to continue moving into the receiving groove, engaging with the adjusting hole on the adjusting end 12. The end of the adjusting end 12 may even extend out of the receiving groove, thereby reducing the clamp diameter. Conversely, rotating the screw in the opposite direction causes the adjusting end 12 to gradually move out of the receiving groove, thereby increasing the clamp diameter or loosening the clamp. In this example, the clamp 1 is adjusted by rotating the screw to regulate its tension.
[0041] In the example, the hoop seat 21 is spot welded to the inner wall of the hoop 1.
[0042] In this embodiment, as Figure 3 As shown, there are two ribs 51, which are symmetrically arranged on the inner wall of the hoop liner 5. Of course, this patent is not limited to this, and multiple ribs can also be arranged at intervals; or, in a second-best solution, one rib is sufficient. In the example, the hoop liner 5 is integrally connected. Specifically, the hoop liner 5 is roll-formed to form the ribs 51 and the limiting edge 52.
[0043] In a preferred embodiment, such as Figures 1-2 As shown, a disc 3 is sleeved on the screw 4. The screw 4 has limiting heads at both ends. The inner diameter of the receiving groove in the hoop 22 is smaller than the outer diameter of the limiting head on the screw 4. The screw 4 is housed within the receiving groove of the hoop 22, which is fixedly connected to the hoop base 21. In this example, the disc has a through-hole. The outer diameter of the limiting head at the end of the screw 4 near the hoop assembly is smaller than the outer diameter of the limiting head at the end of the screw 4 near the disc. The disc is sleeved onto the screw 4 from the end near the hoop assembly. The inner diameter of the disc's inner hole is smaller than the outer diameter of the limiting head at the end of the screw 4 near the disc, and larger than the outer diameter of the limiting head at the end of the screw 4 near the hoop assembly.
[0044] In a preferred embodiment, such as Figures 1-2 As shown, the hoop base 21 and the hoop 22 are riveted and fixedly connected. Specifically, the hoop base 21 has fixing protrusions 211 on both sides, and the hoop 22 has through holes that match the fixing protrusions 211. The fixing protrusions 211 pass through the through holes and are fixedly connected to the hoop 22. In the example, the fixing protrusions 211 are riveted and fixed to the surface of the hoop 22 through the through holes. In the example, each side of the hoop base 21 has two fixing protrusions 211, and each side of the hoop 22 also has a corresponding through hole.
[0045] The specific manufacturing steps for the clamp with ribbed inner lining of this patent are as follows:
[0046] 1. Roll the hoop 1 into a circle, and roll the inner lining 5 of the hoop into a shape to form a rib 51 and a limiting edge 52;
[0047] 2. The hoop housing 21 is spot welded to the inner wall of the fixed end of the hoop using a special welding fixture and equipment;
[0048] 3. Place the disc 3 onto the screw, and house the screw in the receiving groove of the hoop. The fixing protrusion on the hoop seat 21 passes through the corresponding through hole on the hoop 22 and is riveted to the surface of the hoop.
[0049] 4. The adjusting end 12 of the clamp 1 extends into the receiving groove. The adjusting end 12 is located between the fixed end and the screw. The thread on the screw meshes with the adjusting hole of the adjusting end. By rotating the screw, the adjusting end 12 gradually moves into or out of the receiving groove. By rotating the screw, the diameter of the clamp can be adjusted. That is, when the clamp is installed and used, rotating the screw can tighten or loosen the clamp.
[0050] 5. The inner liner 5 of the hoop is fitted onto the inner wall of the hoop 1. The limiting edge of the inner liner 5 is located on both sides of the hoop 1 so that the inner liner 5 is stably fitted into the hoop 1.
[0051] It should be noted that, unless otherwise specified, all features in the above embodiments or embodiments described herein can be combined arbitrarily.
[0052] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "yet another embodiment," "another embodiment," "other embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
