Description
Technical Field
[0001] The utility model relates to the technical field of sealing structures, in particular to a sealing structure of a water supply pipe fitting with a quick locking function. Background Art
[0002] Traditional connections of water supply pipe fittings usually adopt methods such as threaded connection or flange connection. However, these traditional methods have certain limitations: on the one hand, they often require the use of additional tools to complete the installation, which not only increases the complexity and time cost of the operation, but also may be difficult to implement in occasions with limited space; on the other hand, due to the lack of an effective contraction mechanism, loosening may occur during long-term use, resulting in a decline in sealing performance, and further causing problems such as water leakage, which poses challenges to the effective utilization of water resources and environmental protection. In addition, once leakage occurs, traditional pipe fitting connection methods are also not convenient enough in terms of maintenance and repair. Usually, the entire pipeline system needs to be disassembled to make adjustments or repairs, which undoubtedly increases the maintenance cost and workload. Content of the Utility Model

Specific embodiments
[0024] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0025] The present invention relates to a sealing structure for a water supply pipe fitting with a quick locking function, as Figures 1 to 4 shown, including:
[0026] A connecting piece 1, as the core part of the entire pipe fitting, is symmetrically provided with mounting pipes 2 at both ends. The mounting pipes 2 are integrally formed with the connecting piece 1, and tapered threads 21 are provided on the outer wall of the mounting pipes 2. Notch 22 are equally spaced on the distal sides of the two mounting pipes 2, and the notch 22 is used to contract the diameter of the mounting pipe 2;
[0027] A water pipe body 3 is inserted and pulled out from the mounting pipe 2 at one end of the connecting piece 1;
[0028] A sealing gasket 4 is arranged in the inner cavity of the connecting piece 1, usually made of rubber or other materials with good elasticity and durability, and is used for sealing the contact end between the water pipe body 3 and the connecting piece 1;
[0029] A lock nut 5, with an internal tapered thread, is installed in cooperation with the tapered thread 21 on the outer wall of the mounting pipe 2, and is used to clamp the water pipe body 3 by the mounting pipe 2. By rotating the lock nut 5, the mounting pipe 2 can be gradually pressed and the water pipe body 3 can be clamped;
[0030] The specific operation process of this device is as follows:
[0031] Insert the water pipe body 3 into the installation pipe 2 at one end until it touches the gasket 4. After ensuring that the water pipe body 3 is correctly aligned, start rotating the lock nut 5 so that it advances along the tapered thread 21 on the installation pipe 2. As the lock nut 5 rotates, it will exert pressure on the installation pipe 2, and at the same time cause the distal end side of the installation pipe 2 to contract due to the presence of the notch 22, thereby tightly holding the water pipe body 3. Continue to rotate until a distinct resistance is felt, indicating that the locking is in place. At this time, the operation can be stopped, and the above process is repeated for the other end to complete the entire connection; by designing the connecting part 1 as an integrally formed installation pipe 2 symmetrically arranged at both ends, and setting a tapered thread 21 on the outer wall of the installation pipe 2 and a notch 22 for diameter contraction on the distal end side, and cooperating with the lock nut 5 with an internal tapered thread, the connection and sealing between pipe fittings can be simply and quickly completed without the assistance of additional tools; at the same time, due to the presence of the gasket 4, the sealing performance at the contact end between the water pipe body 3 and the connecting part 1 is enhanced, effectively preventing water leakage; in addition, this structure allows the sealing state at the connection to be adjusted or repaired only by rotating the lock nut 5 without disassembling the pipeline, greatly improving the maintenance and repair efficiency, reducing the operation difficulty and time cost, and enhancing the stability and reliability of the overall system.
[0032] As a preferred solution, as Figure 4 shown, it further includes a sealing ring 6. The sealing ring 6 is made of a material with strong weather resistance and good elasticity, and is arranged on the inner wall of the installation pipe 2 for sealing the connection between the water pipe body 3 and the installation pipe 2, providing an additional layer of sealing barrier for the connection to prevent water from leaking from the interface;
[0033] A plurality of limiting grooves 31 are equidistantly arranged on the outer wall of the connecting end of the water pipe body 3 and the limiting grooves 31 are vertical planes on the port side of the water pipe body 3;
[0034] A plurality of protrusions 61 are equidistantly arranged on the sealing ring 6, and the protrusions 61 are engaged with the limiting grooves 31 on the outer wall of the water pipe body 3, and the protrusions 61 will enter the limiting grooves 31 to form a tight engagement;
[0035] By introducing the sealing ring 6 and its unique structural design, the utility model not only strengthens the sealing performance at the connection of the water supply pipe fittings, effectively avoiding water leakage problems caused by pressure changes or long-term use, but also improves the stability and durability of the sealing structure.
[0036] As a preferred solution, as Figure 3 shown, the lock nut 5 is provided with an extension end 51, and a hanging member 52 is arranged on the extension end 51, and the hanging member 52 cooperates with the limiting groove 31 of the water pipe body 3 for restricting the displacement of the water pipe body 3 and the installation pipe 2;
[0037] A plurality of through slots 53 are equidistantly arranged on the extension end 51. The through slots 53 are used for expansion when the water pipe body 3 is inserted. After the extension end 51 is deformed, the restoring force causes the hanging member 52 to be buckled into the limiting slot 31.
[0038] When the water pipe body 5 and the connecting member 1 move in the separating direction, the cooperation between the hanging member 52 and the limiting slot 31 limits their movement, ensuring a stable fit with the gasket 4. When the locking nut 5 rotates, it can also drive the water pipe body 5 to move towards the connecting member 1 through the hanging member 52, further improving the sealing effect.
[0039] As a preferred solution, as Figure 2 and Figure 3 shown, the outer wall of the locking nut 5 is provided with anti-slip threads 54.
[0040] The anti-slip threads 54 in the present utility model increase the friction force, enabling the locking nut 5 to be easily and firmly rotated even without special tools, ensuring the reliability and tightness of the connection. In addition, the design of the anti-slip threads 54 also takes into account the ergonomic principle, optimizing the operation feel, reducing the working intensity of the operator, and improving work efficiency.
[0041] As a preferred solution, as Figure 2 shown, the outer wall of the connecting member 1 is provided with a regular polygon structure 11.
[0042] The regular polygon structure 11 in the present utility model provides multiple flat sides, increasing the contact area with the hand or tool, enabling the operator to grasp the connecting member 1 more firmly, and ensuring sufficient friction force even in a wet or greasy environment to prevent slipping.
[0043] As a preferred solution, as Figure 2 shown, a positioning member 12 is provided in the middle of the connecting member 1 for positioning the installation position of the water pipe body 3 and the connecting member 1.
[0044] The presence of the positioning member 12 significantly improves the accuracy and efficiency of the installation process. It can guide the water pipe body 3 to be accurately inserted into the predetermined position, ensuring that the gasket 4 and other sealing components are in the best working state, thus achieving a more reliable sealing effect.
[0045] For the water pipe fitting sealing structure with a quick locking function of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.
[0046] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
