Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a quick joint for a direct drinking water pipeline. Background Art

[0002] When laying many temporary or short- to medium-term direct drinking water pipe systems, pipes are connected by joints. Since such direct drinking water pipe systems are long and the demand is urgent, quick joints are required. However, the current quick joints have the following defects during use:

[0003] 1. Compared with traditional welding and threaded joints, water pipe quick joints are prone to water leakage during use. The simple structure of the quick joint is connected by external force extrusion. Although this connection method is temporarily reliable, the applied pressure will gradually decrease over time, resulting in water leakage and seepage;

[0004] 2. Regarding 1, there are currently complex quick connectors. Although they can avoid water leakage and seepage, they are complex in structure, high in cost, more prone to damage, and not so quick and convenient to install.

[0005] 3. Lack of protection at the connection. Many quick connectors lack protective structures, which are easily damaged and have low stability in use.

[0006] Therefore, we propose a quick connector for direct drinking water pipes, which has the advantages of avoiding water leakage, simple structure, and stable use of protective structure. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings existing in the prior art. Compared with traditional welding and threaded joints, water pipe quick joints are prone to water leakage during use. Quick joints with simple structures are connected by external force squeezing. Although this connection method is temporarily reliable, the applied pressure will gradually decrease with the increase of time, thus causing water leakage and seepage. Currently, there are quick joints with complex structures. Although they can avoid the problem of water leakage and seepage, they are complex in structure, high in cost, more prone to damage, and relatively not so quick and convenient to install. There is a lack of protection at the connection, and many quick joints lack protective structures, which are easily damaged and have low stability in use.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A quick connector for a direct drinking water pipe, comprising a connector seat and a connector column, wherein the connector column is threadedly connected to the inside of the connector seat, and a protective sleeve is threadedly connected to the periphery of the connector seat and the connector column;

[0010] The joint seat comprises a joint main rod and a joint, the joint main rod and the joint are integrally formed, and the inner and outer parts of the joint are respectively provided with a joint internal thread and a joint external thread;

[0011] The connector column is provided with a thread path on the periphery near the connector seat end, the thread path is threadedly connected to the connector internal thread, and the protective sleeve is simultaneously threadedly connected to the periphery of the thread path and threadedly connected to the connector external thread;

[0012] The protective sleeve is rotated away from the connector seat end so that the protective sleeve is only threadedly connected to the thread path of the connector column.

[0013] Furthermore, a connecting threaded portion is provided on the periphery of one end of the joint main rod and the joint column away from each other, and is connected to pipes at both ends by wrapping a waterproof tape around the connecting threaded portion, or the connecting threaded portion is integrally connected to the pipes at both ends.

[0014] Furthermore, the joint main rod, the joint and the joint column are connected.

[0015] Furthermore, a first waterproof gasket is provided inside the joint near the end of the joint main rod, and a second waterproof gasket is provided at the end of the joint column corresponding to the first waterproof gasket.

[0016] Furthermore, the protective sleeve is in two sections, a section with a smaller diameter is adapted and threadedly connected to the thread path, and a section with a smaller diameter is adapted and threadedly connected to the external thread of the joint.

[0017] Furthermore, the protective cover is made of stainless steel.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] This quick connector design adopts the structure of threaded connection and waterproof gasket, which effectively prevents water leakage caused by pressure reduction after long-term use. The first waterproof gasket inside the connector and the second waterproof gasket on the connector column, as well as the tight threaded connection between the connector seat and the connector column, jointly ensure the sealing of the connector;

[0020] Compared with the quick connector with complex structure, this design maintains the simplicity of structure and reduces the production cost. At the same time, due to the simple structure, installation and maintenance are also more convenient and quick.

[0021] The joint main rod, joint and joint column are tightly connected by threads, and the outer protective cover further enhances the stability and durability of the joint. This design makes the joint not easily damaged when subjected to external force or vibration, ensuring the stability of use.

[0022] The design of the protective cover not only enhances the stability of the connector, but also protects the connection. The protective cover adopts a two-stage design and stainless steel material, which is adapted and tightly threaded to the connector column and connector seat, effectively preventing damage to the connection caused by external force or environmental factors.

[0023] To sum up, the direct drinking water pipe quick connector has effectively solved the problems existing in the prior art through its design, and has the beneficial effects of preventing water leakage and seepage, simple structure and low cost, high stability in use, protection of the connection and convenient installation, and has practical value.
