Description

Technical Field

[0001] The utility model relates to the technical field of catheter connectors, in particular to a novel catheter quick connector. Background Art

[0002] Conduit quick connectors, also known as quick connect / disconnect connectors, can quickly, simply and safely repeatedly connect and disconnect almost any fluid or gas pipeline without using any tools. They can quickly connect two pipes, fittings or hoses, thereby achieving effective transmission of fluid or gas.

[0003] During use, existing catheter joints usually use sealing rings and retaining rings to connect two pipes. Due to the elastic force of the retaining ring, under the action of external force, elastic force may be generated, causing the pipeline to be impacted by force, thereby affecting the stability and sealing of the joint during connection.

[0004] Therefore, those skilled in the art provide a novel catheter quick connector to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to provide a novel catheter quick connector to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A novel catheter quick connector includes a connector 1, one side of which is movably connected to a connector 2, a limiting groove is provided on one side of the connector 1, a limiting block is fixedly connected to one side of the connector 2, the limiting groove is adapted to the limiting block, and a fixing mechanism is provided inside the limiting groove;

[0008] The fixing mechanism includes a pressure plate, which is fixedly connected to the inside of the limiting groove, and one side of the pressure plate is fixedly connected to a fixing piece, and one side of the pressure plate is fixedly connected to a spring through the fixing piece, and a sleeve is sleeved on the outside of the spring, and one end of the sleeve is fixedly connected to a pressure block, and a rubber pad is provided on one side of the pressure block. By installing the fixing mechanism, the first and second joints can be stably connected through the cooperation of the limiting groove and the limiting block and the support of the fixing mechanism during use, and the sealing and fixation of the joint are also enhanced by the fit between the pressure block and the limiting block, thereby avoiding accidental disconnection of the joint when subjected to external force during use, thereby comprehensively improving the stability and sealing of the joint during use.

[0009] As a further solution of the present invention: the outside of the connector one is sleeved with a clamping ring, and a sliding groove is provided on the side wall of the clamping ring near the open end, and a locking block is movably connected to the side wall of the sliding groove, and an annular groove is provided on the side wall of the connector two. The annular grooves are distributed in an annular array, and the annular grooves are adapted to the locking block. The clamping ring serves as an additional fixing component, which can tightly wrap the connector one, and cooperate with the annular groove on the connector two through the locking block in the sliding groove to form a multi-point locking, thereby enhancing the connection between the connector one and the connector two. At the same time, through the movement of the locking block in the sliding groove, the user can quickly install and disassemble the connector by sliding the locking block, thereby reducing the difficulty and complexity of the installation and disassembly process.

Once the indicator light lights up or changes color, it means that there may be an overpressure risk at the connection, thereby reminding the operator to take timely measures to avoid potential safety hazards.

[0014] As a further solution of the present invention: the side surface of the clamping ring is provided with anti-slip grooves, and the side surface of the clamping ring is provided with usage markings. The anti-slip grooves enable the operator to operate stably when installing, removing or adjusting the clamping ring, reducing the risk of accidental injury due to hand slippage, thereby enhancing operational safety.

[0015] As a further solution of the present invention: the interior of the docking groove is movably connected to a connecting pipeline, the connecting pipeline is adapted to the docking groove, and the exterior of the connecting pipeline is sleeved with a valve.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By installing a fixing mechanism, the cooperation between the limit groove and the limit block and the support of the fixing mechanism can stably connect the joint 1 and the joint 2 during use. The fit between the pressure block and the limit block also enhances the sealing and fixation of the joint, preventing the joint from accidentally disconnecting when subjected to external force during use, thereby comprehensively improving the stability and sealing of the joint during use;

[0018] 2. The clamping ring serves as an additional fixing component, which can tightly wrap around connector one and cooperate with the annular groove on connector two through the locking block in the slide groove to form a multi-point locking, thereby strengthening the connection between connector one and connector two. At the same time, the movement of the locking block in the slide groove allows the user to quickly install and remove the connector by sliding the locking block, thereby reducing the difficulty and complexity of the installation and removal process.
