Description

Quick plug with sealing ring fixing compression ring Technical Field The utility model belongs to the technical field of quick plugs, and particularly relates to a quick plug with a sealing ring fixing compression ring. Background In a fluid or gas transmission system, the quick plug is widely applied to various fields such as automobile manufacturing, industrial equipment, aerospace and the like due to the characteristics of convenience and high efficiency in connection. Traditional quick plug internal seal circle mounting means often has the fixed unstable problem of sealing effect. When the sealing ring is influenced by factors such as medium pressure fluctuation, temperature change and the like in the long-term use process, the sealing ring is easy to shift and deform, so that leakage occurs at the joint, resource waste can be caused, and safety accidents can be caused. Part of the quick plug adopts a simple embedding mode to fix the sealing ring, lacks an effective limiting and anti-loosening structure, and is extremely easy to loosen or even fall off under the frequent plugging operation, so that the normal operation of the system cannot be ensured. Meanwhile, in the structural design of the existing quick plug, the tight fit between the sealing ring and the inner wall of the plug is difficult to realize, and the strict requirements on the sealing performance under the complex working conditions of high pressure, high flow speed and the like cannot be met. Therefore, how to design a quick plug with reasonable structure, reliable sealing and firm fixing of the sealing ring becomes a technical problem to be solved urgently. Disclosure of utility model In order to solve the technical problems, the quick plug with the sealing ring fixing compression ring is provided with the sealing ring inside, the quick plug is internally provided with the annular supporting table, the sealing ring fixing compression ring is arranged above the annular supporting table, the sealing ring is positioned between the annular supporting table and the sealing ring fixing compression ring, the sealing ring fixing compression ring is in interference fit with the quick plug, the inner side surface of the sealing ring fixing compression ring is provided with a plurality of inner positioning grooves which are uniformly arranged at intervals, the outer side surface of the sealing ring fixing compression ring is provided with a plurality of outer positioning grooves which are uniformly arranged at intervals, and the inner wall of the quick plug is provided with a plurality of positioning blocks which are matched with the outer positioning grooves and are respectively positioned in the corresponding outer positioning grooves. As the optimization of the technical scheme, the inner wall of the quick plug is provided with the annular bulge and the annular boss, the annular boss is positioned between the annular bulge and the annular supporting table, and the sealing ring is fixedly clamped between the annular bulge and the annular boss. As the optimization of the technical scheme, the two ends of the annular bulge are respectively in smooth transition with the inner wall of the quick plug. Preferably, in the above technical solution, the inner side of the sealing ring fixing compression ring has a guiding inclined plane. As the optimization of the technical scheme, the U-shaped clamp springs are arranged on the quick plug, and side openings into which the U-shaped clamp springs extend are respectively arranged on two sides of the quick plug. The sealing ring clamping device has the beneficial effects that the sealing ring is firmly clamped through the cooperation of the annular supporting table and the sealing ring fixing compression ring, so that displacement deformation of the sealing ring under pressure fluctuation and temperature change is effectively avoided, the sealing performance is greatly improved, leakage is prevented, and the resource waste and the safety risk are reduced. The design of locating piece and external positioning groove has strengthened the connection stability of sealing washer fixed clamping ring and quick plug, cooperates annular bulge and annular boss's spacing, even if frequent plug also is difficult for becoming flexible droing. The inner positioning groove on the inner side of the sealing ring fixing pressure ring can further optimize the installation of the sealing ring, and the inner guiding inclined surface is convenient for assembly. The U-shaped clamp spring provides additional reinforcement for the integral structure, so that the quick plug can stably operate under complex working conditions such as high pressure, high flow rate and the like, and the diversified application requirements are met.
