Description

Technical Field

[0001] This utility model relates to the field of pipe connector structure technology, specifically a quick-assembly and disassembly pipe connector. Background Technology

[0002] In piping systems, pipe fittings are key components for connecting and securing pipes, and their performance directly affects the safety and stability of the entire piping system. During the manufacturing process of pipe fittings, clamping technology is a crucial step in ensuring the quality of the fittings and improving production efficiency.

[0003] While welding can provide high connection strength, its construction process is complex and requires a high level of technical skill from the operators. Furthermore, once the welding is completed, it is difficult to disassemble and replace, which undoubtedly increases the difficulty of later maintenance and modification.

[0004] While flange connections are easy to disassemble, they require precise bolt hole positioning and bolt tightening, making the process cumbersome. Furthermore, they demand high quality from both the flanges and bolts to prevent leaks. Threaded connections, on the other hand, are limited by pipe material and specifications. For non-standard or dissimilar pipes, they often fail to achieve ideal connection results and are susceptible to loosening or leaks due to environmental factors.

[0005] Furthermore, traditional connection methods are particularly inconvenient when dealing with emergency repairs or pipeline modifications, often requiring significant time and manpower for disassembly and reinstallation. This not only affects construction efficiency but also increases costs. Therefore, developing a pipe connector that can be quickly disassembled and assembled, has excellent sealing performance, and is suitable for various pipe specifications and materials has become an urgent technical challenge to be solved in the field of pipeline system engineering.

[0006] Therefore, we propose a quick-assembly and disassembly pipe connector. Utility Model Content

[0007] The purpose of this invention is to provide a quick-assembly and disassembly pipe connector to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides a quick-assembly and disassembly pipe connector, including a fixing mechanism and an integrally formed connecting mechanism. The connecting mechanism includes an axial limiting section, with pipe cavities fixedly connected to both ends of the axial limiting section. A sealing cavity containing a sealing element is fixedly connected to the end of the pipe cavity, and a guide sleeve is provided at the end of the sealing cavity. The fixing mechanism includes an arc-shaped sleeve and a spring cavity that are connected and fixed to each other. A pipe insertion port is fixedly connected to the end of the arc-shaped sleeve. An arc-shaped retaining ring is sleeved inside the arc-shaped sleeve, and the arc-shaped retaining ring presses against a spring located in the spring cavity. The guide sleeve is inserted into the spring cavity, and the spring is sleeved on the outer surface of the guide sleeve and welded to the guide sleeve.

[0009] Preferably, the back of the arc-shaped retaining ring is an arc.

[0010] Preferably, the back of the arc-shaped retaining ring forms a 7-degree angle with the retaining teeth, the arc of the tooth tip of the arc-shaped retaining ring is consistent with the inserted pipe, and each retaining tooth of the arc-shaped retaining ring is aligned with the surface of the pipe.

[0011] Preferably, the cross-section of the arc-shaped retaining ring is C-shaped.

[0012] Preferably, the pipe insertion end of the arc-shaped sleeve is provided with a waterproof sealing sleeve.

[0013] Preferably, an arc-shaped retaining ring is installed inside the fixing mechanism, and the spring and sealing mechanism are assembled and welded together to form a single workpiece; wherein, at the welded joint: the welded joint has an inward arc-shaped chamfer to match the shape of the sealing cavity of the sealing mechanism, increasing the contact surface of the weld.

[0014] Preferably, a pipe release device is inserted into the end of the pipe insertion port. The pipe release device is a fixed pipe release device, which consists of two semi-circular ring clamps that are hinged to each other.

[0015] Preferably, a pipe release device is inserted into the end of the pipe insertion port. The pipe release device is a variable diameter pipe release device, which is composed of multiple arc-shaped retaining rings. Two adjacent arc-shaped retaining rings are fixed by inserting pins.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model's quick-connect pipe fitting, through its innovative structural design, enables rapid connection and disassembly of pipes. During connection, simply insert the pipe into the insertion port; the arc-shaped retaining ring, under the action of a spring, automatically engages with the outer surface of the pipe, forming a stable connection. During disassembly, simply release the retaining force of the arc-shaped retaining ring using a pipe release tool to easily pull out the pipe. This design greatly simplifies the operation process and improves construction efficiency, making it particularly suitable for emergency repairs and pipe modifications. The sealing cavity of this utility model contains a high-performance seal; when positive or negative pressure is generated inside the pipe, the seal will not experience axial sliding or friction, effectively preventing fluid leakage. Simultaneously, the guide sleeve design ensures the accuracy and stability of pipe insertion, further improving sealing performance. This excellent sealing performance provides strong protection for the safe operation of the pipeline system. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a quick-assembly and disassembly pipe connector, including a fixing mechanism and an integrally formed connecting mechanism. The connecting mechanism includes an axial limiting section 1, with a pipe cavity 2 fixedly connected to both ends of the axial limiting section 1, and a sealing cavity 3 containing a sealing element fixedly connected to the end of the pipe cavity 2. A guide sleeve 4 is provided at the end of the sealing cavity 3.

[0026] In this application, when positive or negative pressure is formed inside the pipeline, the seal will not slide or rub, thereby improving the sealing performance and service life of the seal and forming an independent sealed cavity.

[0027] The function of the axial limiting section 1 is to ensure that the insertion dimensions at both ends of the connecting mechanism are consistent when the pipe is inserted, and to ensure that the pipe and the sealing element have sufficient sealing contact surface.

[0028] The function of the guide sleeve 4 is to extend outward from the sealing cavity 3 and form the guide sleeve 4. When the pipe is inserted, the pipe opening will not scratch the seal, forming a fixed sealing pressure, and preventing the inserted pipe from shaking radially. This ensures that the connecting mechanism and the pipe are on the same axis and precisely locks the toothed ring of the arc-shaped retaining ring 8 onto the pipe.

[0029] It is worth noting that the manufacturing process and technical requirements for the connecting mechanism are as follows:

[0030] First, the semi-finished welded pipe is laser-cut to the specified size;

[0031] Secondly, the internal high-pressure molding process results in one-time molding without scratches or burrs on the inner and outer walls. The sealing cavity has high dimensional accuracy and can mold multiple workpieces at once, resulting in high efficiency, high pass rate, and significantly reduced production costs.

[0032] Finally, stainless steel shot blasting improves surface corrosion resistance and extends product lifespan.

[0033] The fixing mechanism includes an arc-shaped sleeve 5 and a spring cavity 6 that are connected and fixed to each other. A pipe insertion port 7 is fixedly connected to the end of the arc-shaped sleeve 5. An arc-shaped retaining ring 8 is sleeved inside the arc-shaped sleeve 5. The arc-shaped retaining ring 8 presses against a spring 9 located inside the spring cavity 6. The guide sleeve is inserted into the spring cavity 6. The spring 9 is sleeved on the outer surface of the guide sleeve and welded to the guide sleeve.

[0034] The function of the arc-shaped sleeve 5 in this application is as follows: when the toothed ring of the arc-shaped retaining ring 8 slides outward, the diameter of the arc-shaped retaining ring 8 shrinks until the tooth tip is in close contact with the inserted pipe and forms a certain engagement with the outer surface of the inserted pipe, so that the pipe will not move axially, thereby achieving the effect of complete edge connection. The arc-shaped retaining ring 8 is formed in one step.

[0035] Furthermore, the back of the arc-shaped retaining ring 8 adopts a multi-arc design to reduce the friction between the arc-shaped retaining ring 8 and the outer ring of the fixing mechanism, so that the arc-shaped retaining ring 8 always adheres to the outer surface of the inserted pipe, ensuring that the installed pipe is 100% locked.

[0036] The back of the arc-shaped retaining ring 8 is designed at a 7-degree angle to the retaining teeth. The curvature of the tooth tips of the arc-shaped retaining ring 8 is consistent with the inserted pipe. Each retaining tooth of the arc-shaped retaining ring 8 is aligned with the surface of the pipe, which greatly increases the friction with the pipe.

[0037] The arc-shaped retaining ring 8 design allows for radial pull-out force when there is pressure inside the pipe. The greater the pull-out force, the greater the pull-out resistance of the arc-shaped retaining ring 8. The axial direction of the back of the arc-shaped retaining ring 8 is also larger. The arc-shaped retaining ring 8 design increases the force-bearing area, making the outer ring of the fixing mechanism less prone to deformation.

[0038] The arc-shaped retaining ring 8 adopts a C-mouth design to overcome the diameter tolerance during pipe manufacturing;

[0039] The pipe insertion end of the arc-shaped sleeve 5 is equipped with a waterproof sealing sleeve. After the pipe is inserted and connected, it is sealed by the waterproof sealing sleeve to prevent rainwater and splashing water from entering the connection mechanism and extend the service life of the outlet ring and spring 9.

[0040] The arc-shaped retaining ring 8 and the spring 9 are installed inside the fixing mechanism and then assembled and welded with the sealing mechanism to make it a whole workpiece.

[0041] Among them, the welded joint has an inward arc chamfer to match the shape of the sealing cavity 3 of the sealing mechanism, increasing the contact surface of the weld. Through laser welding, the inner surface of the sealing cavity 3 is protected from oxidation and deformation, ensuring that the sealing cavity 3 is effectively sealed.

[0042] It is worth noting that, in order to further improve the flexibility and convenience of pipe connection, a pipe release device is inserted into the end of the pipe insertion port 7. The pipe release device is divided into a fixed pipe release device 11 and a variable diameter pipe release device 12. The fixed pipe release device 11 is composed of two semi-circular ring clamps that are hinged to each other and is suitable for pipe connection of specific specifications. The variable diameter pipe release device 12 is composed of multiple arc-shaped clamps. Two adjacent arc-shaped clamps are fixed by being inserted with a pin and can be flexibly adjusted according to the pipe diameter to meet the connection requirements of pipes of different specifications.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
