Anti-pinch ring copy link clasp

Abstract

This utility model provides an anti-pinch ring clamp, comprising two mating clamp bodies. Each clamp body has an installation groove for inserting a sealing ring. At least one clamp body has a clearance notch at the opening of its installation groove, allowing the sealing ring to move under pressure and deformation. The beneficial effects of this utility model are: by providing a clearance notch at the opening of the clamp body's installation groove, the clamp body can create clearance space for the sealing ring when locking it. This allows the sealing ring to be partially accommodated within the clearance space after being compressed, preventing the sealing ring from being trapped due to its size within the inner cavity, thereby improving the sealing performance and service life of the sealing ring.

Description

Technical Field

[0001] This utility model belongs to the field of pipe connection technology, specifically a clamp. Background Technology

[0002] Pipe clamps are a type of connector used for pipe connections. They typically consist of two mating clamp bodies with a sealing ring between the clamp body and the pipe connection. The clamp body presses against the sealing ring to seal the pipe connection, ensuring a secure connection between the two pipes. However, due to manufacturing tolerances in the sealing ring and pipe, and uneven height of the sealing ring, the outer diameter of the sealing ring may become trapped at the parting line of the two clamp bodies. Over time, this trapping can damage the sealing ring, especially in high-pressure pipeline systems. Once this trapping occurs, the sealing ring cannot withstand the impact of high pressure and will quickly fail, leading to leakage in the clamp joint. This can eventually cause leakage throughout the entire pipeline, and in more severe cases, damage to other equipment within the pipeline, with extremely serious consequences. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to prevent the sealing ring from being damaged during hoop connection.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A type of anti-pinch ring clamp includes two mating clamp bodies, each with an installation groove for inserting a sealing ring. At least one of the clamp bodies has a clearance notch at the opening of its installation groove, which allows the sealing ring to make way when it is deformed under pressure.

[0006] Preferably, the clearance notch is provided along each groove wall of the mounting groove.

[0007] As a preferred option, both ends of the mounting slots of the two hoop bodies are provided with clearance notches.

[0008] Preferably, the clearance notch is a sloped or curved surface structure.

[0009] Preferably, the groove depth of the clearance notch end face is greater than that of the end furthest from the end face.

[0010] Preferably, the length of the clearance notch is 3-20mm; the depth of the clearance notch on the bottom surface of the mounting groove is 0.5-2mm; and the depth of the clearance notch on the side surface of the mounting groove is 0.5-2mm.

[0011] Preferably, the inner surface of the hoop located on both sides of the mounting groove is provided with raised ribs.

[0012] The beneficial effects of this utility model are: by setting a clearance notch at the groove opening of the hoop mounting groove, this utility model can provide clearance space for the sealing ring when the hoop is locking the sealing ring, so that the sealing ring can be partially accommodated in the clearance space after being compressed, preventing the sealing ring from being clamped in the inner cavity due to the size of the sealing ring, thereby improving the sealing performance and service life of the sealing ring.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figures 1-4The figure shows a type of anti-pinch ring clamp, including two mating clamp bodies 1. The clamp body 1 has an installation groove 11 for inserting a sealing ring 2. The inner surface of the clamp body 1 on both sides of the installation groove 11 has raised ribs 12. These two raised ribs 12 are used to clamp onto two connected pipes to achieve the connection between the pipes. The sealing ring 2 is set at the interface between the clamp body 1 and the pipe to achieve the seal at the interface. It is worth noting that in this embodiment, at least one of the clamp bodies 1 has a clearance notch 13 at the groove opening of the installation groove 11, which makes way for the sealing ring 2 when it is deformed by pressure. The groove opening of the installation groove 11 is located at the installation groove 11 position on both end faces of the semi-circular clamp body 1. The setting of the clearance notch 13 ensures that after the two clamp bodies 1 are mated and locked, the part of the sealing ring 2 that is squeezed out is placed at the clearance notch 13, so that the sealing ring 2 will not be damaged locally, thereby ensuring the integrity of the sealing ring 2 and achieving a better sealing effect.

[0021] In this embodiment, the clearance notch 13 is provided along each groove wall of the mounting groove 11, which provides clearance space on each surface where the sealing ring 2 contacts the hoop 1, thus providing all-round protection for the sealing ring 2.

[0022] In this embodiment, both ends of the mounting groove 11 of the two hoop bodies 1 are provided with clearance notches 13. In this embodiment, both ends of the groove of the two hoop bodies 1 are provided with clearance notches 13, so that a large clearance space is formed after the two hoop bodies 1 are connected. This also ensures that there are no sharp edges at the contact position between the groove of the two hoop bodies 1 and the sealing ring 2, thereby further ensuring that the sealing ring 2 is not easily damaged and improving the service life of the sealing ring 2.

[0023] In this embodiment, the clearance notch 13 is a sloping or curved surface structure. The groove depth at the end face of the clearance notch 13 is greater than that at the end furthest from the end face, thus forming a larger notch together after the two hoop bodies 1 are joined. Figure 3 and Figure 4 As shown, in this embodiment, the length of the clearance notch 13 is any value within the range of 3-20mm, that is, as... Figure 3 The length range of section A; the depth of the clearance notch 13 on the bottom surface of the mounting groove 14 is any value within the range of 0.5-2mm, that is, as shown in the figure. Figure 3 The length range of section B; the depth of the clearance notch 13 on the side of the mounting groove 15 is any value within the range of 0.5-2mm, that is, as shown in the figure. Figure 4 The optimal value for the length range of section C is determined based on the pipe size. For example, if the pipe diameter is small, the sealing ring 2 should be small, and its notch length or depth can be smaller. This is because if the sealing ring 2 is small, the amount extruded when it is squeezed will be relatively small, so there is no need to design such a large clearance space. Furthermore, if the clearance space is too large, it will cause leakage at the clearance space location, affecting the sealing performance at the interface.
