Description

Technical Field

[0001] This utility model belongs to the field of vehicle accessories technology, specifically a Lock ring structure for connecting metal tubes. Background Technology

[0002] Traditional metal pipe connection methods (such as welding and threaded connections) suffer from problems such as complex operation, insufficient sealing, or the need for specialized tools. While the lock ring structure, as a mechanical crimping connection, offers the advantage of convenient installation, existing structures often rely on sealing rings for sealing, which carries risks such as sealing ring aging and detachment. Therefore, an improved lock ring structure is proposed, which enhances connection reliability and sealing durability through the synergistic effect of tool crimping and sealing fluid. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a Lock ring structure for metal pipe connection, which effectively solves the problems mentioned in the background.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a Lock ring structure for connecting metal pipes, comprising a main body, wherein the main body has a hollow cavity inside, and the hollow cavity is provided with a short horizontal section, a slightly inclined section, a long horizontal section, a flared section and an arc-shaped section from left to right; the main body has an inner concave annular groove on the outside, and an open annular groove on one side of the inner concave annular groove.

[0005] Preferably, the main body is made of metal.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] 1. High sealing performance: Mechanical seal is achieved through tool crimping, combined with the chemical bonding and filling effect of the sealing fluid to form a double sealing barrier, which significantly improves the sealing performance of the joint. Moreover, there is no need to pre-assemble the sealing ring. The seal can be completed by dripping the sealing fluid, which simplifies the installation process and is suitable for rapid on-site construction.

[0008] 2. Easy to install: The open ring groove design allows the LOCK ring to be easily fitted onto the pipes to be connected. During installation, the LOCK ring can be fitted onto the end of the pipe from one side of the open ring groove, and then the LOCK ring can be squeezed with crimping pliers to make it firmly fixed on the pipe and achieve a sealed connection.

[0009] 3. Stress relief: In pipeline systems, due to factors such as temperature changes and pipeline vibration, certain stresses will be generated in the pipeline. The open annular groove on the Lock ring can allow the Lock ring to have slight deformation to a certain extent, thereby releasing the stress generated by various factors in the pipeline, avoiding cracks or loosening at the pipeline connection due to stress concentration, and improving the reliability and stability of the connection.

[0010] 4. Auxiliary positioning: The open ring groove can be used as a positioning mark during installation to help operators accurately install the Lock ring in the correct position on the pipeline. For some Lock rings that require a specific installation direction, the open ring groove can also serve as a direction indicator to prevent installation errors. Attached Figure Description

[0011] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example 1, by Figures 1-3 The present invention relates to a Lock ring structure for connecting metal pipes, comprising a main body 1, a hollow cavity inside the main body 1, and a short horizontal section 2, a slightly inclined section 3, a long horizontal section 4, a flared section 5 and an arc-shaped section 6 arranged sequentially from left to right in the hollow cavity; a concave annular groove 7 is provided on the outside of the main body 1, and an open annular groove 8 is provided on one side of the concave annular groove 7.

[0019] With the design of the open annular groove 8, in the pipeline system, due to factors such as temperature changes and pipeline vibration, the pipeline will generate a certain stress. The open annular groove 8 on the Lock ring can allow the Lock ring to have a small deformation to a certain extent, thereby releasing the stress generated by the pipeline due to various factors, avoiding cracks or loosening at the pipeline connection due to stress concentration, and improving the reliability and stability of the connection.

[0020] In addition, the open ring groove 8 can serve as a positioning mark during installation, helping operators to accurately install the Lock ring in the correct position on the pipeline. During installation, operators can observe the position of the open ring groove 8 to ensure the fit accuracy between the Lock ring and the pipeline and guarantee the connection quality. At the same time, for some Lock rings that require a specific installation direction, the open ring groove 8 can also serve as a direction indicator to prevent installation errors and can play an auxiliary positioning role.

[0021] The main body 1 is made of metal.

[0022] Working principle: Insert two metal pipes into the two ends of the main body 1 respectively. At the same time, drip an appropriate amount of sealing liquid onto the outer wall of the pipe ends to coat the outer wall of the pipe. Then, use a special crimping tool to apply clamping and squeezing force to the outside of the main body 1. The sealing liquid and the hollow cavity inside the main body 1 fill the connection gap through capillary action, so that the main body 1 and the pipe are nested and pressed tightly, and fixed on the pipe to achieve a sealed connection.
