Description

Technical Field

[0001] The utility model relates to the technical field of exhaust system connectors, in particular to a simple and efficient exhaust system connector. Background Art

[0002] Exhaust system connectors are installed on the exhaust system and are used to connect pipe interfaces or gas transition parts. They are annularly sleeved between two pipes and are also called clamps.

[0003] To ensure the normal circulation of the medium in the system and the normal operation of the whole machine. Selecting different types of clamps according to the characteristics of the pipeline system and the use environment can improve the reliability of the system and pipelines and effectively control the occurrence of oil, air and water leakage.

[0004] The current clamp has poor sealing performance and does not evenly apply force to the inner mounting member as the bending angle opens and closes.

[0005] Therefore, there is still a need for a simple and efficient exhaust system connector to solve the above problems. Utility Model Content

[0006] The utility model provides a simple and efficient exhaust system connector for solving the above problems.

[0007] The purpose of this utility model is achieved by the following technical solutions:

[0008] A simple and efficient exhaust system connection, comprising:

[0009] The clamping portion has a V-shaped cross section and is in an arc shape with an opening when no external force is applied;

[0010] The connecting part is respectively connected to the openings on both sides of the clamping part. The connecting part protrudes from the outer surface of the clamping part and has a connecting hole. The connecting hole is used for the connecting piece to pass through so that the clamping part maintains an overall circular state.

[0011] In one embodiment, a gasket is further included, which is in the shape of a circular ring as a whole, and in the axial direction of the circular ring, one end of the gasket is formed with a limiting portion evenly distributed along the arc, and the other end is formed with a hook extending from the root of the limiting portion. The limiting portion is offset toward the axis as a whole, and the hook is used to hang the gasket and connect at least part of the gasket to the inner side of the clamping portion.

[0012] In one embodiment, the gasket is in an inward-retracted shape as a whole in the axial direction of the ring, approaching the axis.

[0013] In one embodiment, the number of the limiting parts is 3-9.

[0014] In one embodiment, the connecting member includes a bolt and a nut, and the shape of the connecting hole is polygonal. When the clamping portion is in a circular state, the bolt or the nut is sleeved in the connecting hole.

[0015] In one embodiment, the connecting portion is on a diameter extension line of the circle formed by the clamping portions.

[0016] Compared with the prior art, the beneficial effects of the present invention include at least:

[0017] When in use, manually press the connection part on one side, and then press the other side with the other hand, so that the clamping part can be evenly deformed until it becomes a circular state when fully buckled. At this time, the clamping part can evenly buckle the outside of the pipe, provide uniform stress in the circumferential direction of the pipe, and provide good sealing.

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0024] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0025] Reference Figure 1-4 The utility model provides a simple and efficient exhaust system connector 3, comprising: a clamping part 1 and a connecting part 2. The cross section of the clamping part 1 is V-shaped, and in the absence of external force, the whole is in the shape of an arc with an opening. The connecting part 2 is respectively connected to the openings on both sides of the clamping part 1. The connecting part 2 protrudes from the outer surface of the clamping part 1 and has a connecting hole 21. The connecting hole 21 is used for the connector 3 to pass through, so that the clamping part 1 remains in a circular state as a whole. The clamping part 1 is an overall annular component. When working, the annular component is in the shape of an arc when not subject to external force, and the arc has an opening. When in use, the worker grabs the connecting part 2 by hand, and uses the grip to buckle the clamp, and then passes the connector 3 through the hole on the connecting part 2 and locks it to buckle the clamp 1. The clamping part 1 can be buckled with one hand, and the clamping part 1 after buckling can evenly restrain the outer wall of the pipeline, so that the pipeline can be evenly stressed and will not be damaged due to excessive local stress, thereby providing good sealing.

[0026] Preferably, a gasket 4 is further included, the gasket 4 being in the shape of a circular ring as a whole, and having a limiting portion 41 evenly distributed along the arc formed at one end of the gasket 4 in the axial direction of the circular ring, and a hook 42 formed at the other end, extending from the root of the limiting portion 41, the limiting portion 41 being offset toward the axis as a whole, and the hook 42 being used to hook the gasket 4 and connect at least part of the gasket 4 to the inner side of the clamping portion 1. The limiting portion 41 is in the shape of an inward buckle extending toward the inside as a whole, and when connected, one side of the gasket 4 is hooked to the opening between the clamping portions 1 through the hook 42, and the other end is connected to the limiting portion 41 to buckle the inner pipeline. When working, the inner pipeline is tightly embraced by the limiting portion 41, which can effectively lock the pipeline, prevent the pipeline from rotating or shifting, and provide sufficient sealing.

[0027] Preferably, the gasket 4 is in an inward-contracted shape as a whole, approaching the axis, in the axial direction of the ring. Furthermore, the gasket 4 has an inward-contracting tendency as a whole, which can effectively fit inside the clamping portion 1, ensuring the sealing of the clamping portion 1 and preventing the constrained pipe from leaking gas or liquid due to a loose seal.

[0028] Preferably, the number of the limiting parts 41 is 3 to 9. The connectors 3 of the limiting parts 41 can effectively hold the inner pipe tightly and fix the outer wall of the pipe.

[0029] Preferably, the connector 3 includes a bolt and a nut, and the connection hole 21 is polygonal in shape. When the clamping portion 1 is in a circular state, the bolt or nut is inserted into the connection hole 21. During the tightening process, the stud of the bolt will gradually rotate into the connection hole 21, forming an interlocking structure with the connection hole 21, preventing the bolt from falling out of the connection hole 21, thereby weakening the sealing effect of the clamping portion 1 on the pipeline and causing gas or liquid leakage.

[0030] Preferably, the connecting portion 2 is on a diameter extension line of the circle formed by the clamping portion 1. The connecting portion 2 is perpendicular to the clamping portion 1. When working, the user can hold and clamp the two parts with one hand, so that the clamping portion 1 quickly and evenly forms a circle.

[0031] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
