[0031] First embodiment

[0032] Please refer to Figure 1 The embodiment provides a endless clamp 100, including the hoop body 110 curled into an oval shape and the dismounting unit 120 arranged on the hoop body 110.

[0033] By curling the hoop body 110 into an oval shape, when the hoop body 110 is sleeved on the pipeline, preliminary positioning can be carried out, so that the hoop body 110 is prevented from being randomly displaced on the pipeline, and meanwhile, the oval structure also provides additional space for the pipe fitting to be inserted into the pipeline, so that smooth insertion of the pipe fitting is ensured, and the installation efficiency of the endless clamp 100 and the pipe fitting is improved.

[0034] The opposite ends of the hoop body 110 are respectively a first fixed end 111 and a second fixed end 112, the first fixed end 111 is located outside the second fixed end 112, and the first fixed end 111 and the second fixed end 112 are curled to form an overlapping area 113 on the hoop body 110, and the outer ring part of the overlapping area 113 and the inner ring part of the overlapping area 113 are positioned and connected.

[0035] In the embodiment, three positioning holes 114 are arranged on the outer ring part of the overlapping area 113, and three positioning protrusions 115 are arranged on the inner ring part of the overlapping area 113, the positioning protrusions 115 are arranged one by one corresponding to the positioning holes 114, so that the positioning protrusions 115 are accommodated in the positioning holes 114.

[0036] In the embodiment, the three positioning protrusions 115 are uniformly spaced.

[0037] In the embodiment, the height of the positioning protrusions 115 is greater than the depth of the corresponding positioning holes 114.

[0038] In the embodiment, the positioning protrusions 115 are inclined protrusion structures with increasing height in the direction close to the first fixed end 111, and the positioning protrusions 115 are configured as structures that can be driven to be pressed down or protruded, so that the positioning protrusions 115 can pass through the positioning holes 114 one by one without being stuck in the positioning holes 114 during the compression process of the endless clamp 100.

[0039] In the embodiment, after the hoop body 110 is crimped and formed, the end of the second fixed end 112 is composed of a guide piece 116, and the inner surface of the hoop body 110 is provided with a guide groove 117, and the guide piece 116 is accommodated in the guide groove 117.

[0040] Specifically, the guide groove 117 is located in the non-overlapping area 113 of the hoop body 110 and extends to the outer ring part of the overlapping area 113 with the guide piece 116, so that the guide piece 116 and the guide groove 117 are arranged correspondingly.

[0041] Please refer to Figure 2 , the disassembly unit 120 includes a fixing piece 121, a positioning piece 122 and a disassembly piece 123.

[0042] The fixing piece 121 is provided with a sliding groove 1211, the disassembly piece 123 has an operating end 1231 and a disassembly end 1232 at the two ends in the axial direction, and the operating end 1231 and the disassembly end 1232 are located on both sides of the through hole arranged in the radial direction on the disassembly piece 123, and the positioning piece 122 passes through the through hole of the disassembly piece 123 and is accommodated in the sliding groove 1211 of the fixing piece 121; the surface of the fixing piece 121 away from the disassembly piece 123 is mounted on the hoop body 110 close to the first fixed end 111, and the sliding groove 1211 is in the same direction as the annular crimping direction of the hoop body 110, so that when the positioning piece 122 moves in the sliding groove 1211, the disassembly end 1232 abuts against the first fixed end 111 to disassemble.

[0043] The dismounting unit 120 is arranged on the hoop body 110. When dismounting is needed, the dismounting piece 123 can be slid to contact the first fixed end 111 of the hoop body 110 through the sliding groove 1211, and then the dismounting end 1232 is lifted up by operating the operation end 1231 with the positioning piece 122 as the center by using the lever principle, so that the hoop body 110 is dismounted without tools and damage, the dismounting difficulty of the endless clamp 100 is reduced, and the service life of the endless clamp 100 is prolonged. During the installation of the clamp, the dismounting piece 123 can be slid away from the first fixed end 111 of the hoop body 110 through the sliding groove 1211, so that the dismounting piece 123 does not affect the compression process of the endless clamp 100.

[0044] In the embodiment, the fixing piece 121 is arc-shaped and arranged concentrically with the hoop body 110, so that the installation and arrangement are facilitated.

[0045] In the embodiment, the dismounting end 1232 of the dismounting piece 123 is in the shape of a triangular prism, and the operation end 1231 is in the shape of a quadrangular prism, so that the tip of the dismounting end 1232 is better clamped between the first fixed end 111 and the inner ring part of the overlapping area 113, and the first fixed end 111 is easily lifted up.

[0046] In the embodiment, the opposite ends of the positioning piece 122 are provided with limiting blocks 1221, so that the fixing piece 121 and the dismounting piece 123 are prevented from falling out, and the rotating process of the fixing piece 121 and the dismounting piece 123 is more stable.

[0047] The embodiment also provides a clamp type connecting pipe fitting, which comprises a pipe fitting and the above-mentioned endless clamp 100. The pipe fitting comprises a core part, the endless clamp 100 is arranged in correspondence with the core part at intervals, and the interval between the endless clamp 100 and the core part is used to accommodate a pipeline.

[0048] The embodiment provides a clamp type connecting pipe fitting, and the working principle is as follows:

[0049] The pipeline is installed between the endless clamp 100 and the core part. Since the shape of the endless clamp 100 is elliptical, the short axis direction of the endless clamp 100 can preliminarily position the pipeline, so that the endless clamp 100 is prevented from being randomly displaced. After the pipeline, the endless clamp 100 and the pipe fitting are installed, the position of the endless clamp 100 is adjusted to correspond to the core part of the pipe fitting, then the endless clamp 100 is compressed, the guide piece 116 extends into the guide groove 117, and the compression stability of the endless clamp 100 is ensured. During the process that the guide piece 116 extends into the guide groove 117 and the endless clamp 100 is gradually compressed, the area of the overlapping area 113 increases, the positioning protrusion 115 extends into the positioning hole 114 to be fixed, and the installation of the endless clamp 100 is completed.

[0050] When the endless clamp 100 needs to be disassembled, the positioning member 122 is moved in the sliding groove 1211 of the fixing member 121, so that the disassembling end 1232 of the disassembling member 123 is clamped between the first fixing end 111 and the inner ring part of the overlapping area 113, the disassembling end 1232 is lifted by operating the operation end 1231, so that the first fixing end 111 is lifted, the positioning protrusion 115 and the positioning hole 114 close to the first fixing end 111 are separated, and the disassembly of the endless clamp 100 is completed without damage, quickly and without using additional tools.

[0051] The preferred embodiments of the utility model are merely used for limiting the utility model, and the utility model can be changed and varied for the person skilled in the art. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.
