Description

Technical Field

[0001] This utility model belongs to the field of automotive piping technology, specifically relating to a pipe connector disconnector. Background Technology

[0002] In today's numerous industrial sectors and various complex engineering systems, pipe fittings, as key components connecting various pipelines and ensuring smooth media transmission, are widely used in many industries such as automobile manufacturing, aerospace, chemical production, and electronic equipment heat dissipation systems. However, existing pipe fitting connection and disassembly technologies face a series of challenging problems that urgently need to be solved.

[0003] Traditional pipe fitting connections mostly rely on simple plugging and unplugging followed by forceful locking, or tightening with screw threads to achieve a secure connection. These conventional methods have significant drawbacks during disassembly: firstly, forceful plugging, unplugging, or tightening operations can easily cause wear, deformation, or even breakage of the pipe fitting itself. For example, in the repair of cooling pipes around a car engine, technicians often need to use considerable force to pry off old pipe fittings. Slight carelessness can cause damage such as stripped threads and dented pipe walls, rendering the individual fitting unusable and potentially causing more serious system malfunctions due to debris falling into the pipes, significantly increasing repair costs and time. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, this utility model provides a pipe connector disconnector to solve the problems that the pipe connector itself is easily worn, deformed, or even broken and scrapped due to forceful insertion, pulling or twisting operations in the existing technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The pipe connector disconnector includes a male plug, a female plug, and a disconnector. The male plug has a protrusion inside, and the female plug has a clip inside. The protrusion inside the male plug passes through the clip inside the female plug for fixation. The disconnector is inserted into the female plug to expand the clip and pull out the male plug.

[0007] Furthermore, the female connector includes a locking section, a connecting section, and an inserting section. The connecting section is located between the locking section and the inserting section. The inner diameter of the connecting section is smaller than that of the locking section, and the inner diameter of the inserting section is smaller than that of the connecting section.

[0008] Furthermore, the clip is located inside the locking section, and the locking section is also provided with a groove. The groove is located inside the clip. The clip includes a clip plate and an expansion groove. The clip plate is raised towards the inside of the locking section, and the expansion groove is located at the connection between the clip plate and the groove.

[0009] Furthermore, the card plate includes an inclined surface, an arc-shaped surface, and a turning surface. The arc-shaped surface is located at the top of the inclined surface, the turning surface is located at both ends of the arc-shaped surface, and a slope is provided at the connection between the inclined surface and the arc-shaped surface.

[0010] Furthermore, the connecting section is provided with multiple annular grooves.

[0011] Furthermore, the outer side of the embedded section is provided with multiple sets of connecting protrusions, which are used to snap into the inside of the pipe.

[0012] Furthermore, a protective sleeve is provided on the outside of the locking section.

[0013] Furthermore, a first sealing ring is provided on the outside of the embedded section.

[0014] Furthermore, a second sealing ring is provided inside the connecting section.

[0015] Furthermore, the disassembly tool includes a handle and an insertion part, the insertion part being fixedly connected to the handle, and the insertion part being semi-circular.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention enables non-destructive insertion and removal, and is simple and efficient to operate, making it unrestricted by specific industries or scenarios. Whether it's the frequent debugging of small pipe joints on various instruments and equipment in scientific research laboratories, the temporary assembly and disassembly of a large number of pipe components during the trial production stage of automobile manufacturing and industrial production lines, or the maintenance of delicate internal pipelines in electronic products, it can perfectly adapt to any situation involving repeated insertion and removal of pipe joints, demonstrating extremely strong versatility.

[0030] Example

[0031] like Figures 1-6 As shown, the pipe connector disconnector includes a male plug 1, a female plug 2, and a disconnector 3. The male plug 1 has a protrusion 10 inside, and the female plug 2 has a clip 20 inside. The protrusion inside the male plug 1 passes through the clip 20 inside the female plug 2 for fixation. The disconnector 3 is inserted into the female plug 2 to expand the clip 20 and pull out the male plug 1. The female plug 2 includes a locking section 21, a connecting section 22, and an inserting section 23. The connecting section 22 is located between the locking section 21 and the inserting section 23. The inner diameter of the connecting section 22 is smaller than that of the locking section 21, and the inner diameter of the inserting section 23 is smaller than that of the connecting section 22.

[0032] The clip 20 is located inside the locking section 21. The locking section 21 is also provided with a groove 210. The groove 210 is located inside the clip 20. The clip 20 includes a clip plate 200 and an expansion groove 201. The clip plate 200 is raised towards the inside of the locking section 21. The expansion groove 201 is located at the connection between the clip plate 200 and the groove 210. The clip plate 200 includes an inclined surface 202, an arc surface 203 and a turning surface 204. The arc surface 203 is located at the top of the inclined surface 202 and the turning surface 204 is located at both ends of the arc surface 203. A slope 205 is provided at the connection between the inclined surface 202 and the arc surface 203. A first sealing ring 231 is provided outside the embedding section 23 and a second sealing ring 221 is provided inside the connecting section 22. The remover 3 includes a handle 31 and an insertion part 32. The insertion part 32 is fixedly connected to the handle 31 and is semi-circular.

[0033] The connecting section 22 is provided with multiple annular grooves 220, the inserting section 23 is provided with multiple sets of connecting protrusions 230 on the outside, the connecting protrusions 230 are used to be inserted into the pipe, and the locking section 21 is provided with a protective sleeve 211 on the outside.

[0034] In practical use, the disassembly tool 3 is inserted into the hole of the female connector 2 along the circle of the male connector 1. The female connector 2 has a non-removable clip 20 inside. The function of the clip 20 is to allow insertion but not removal. The disassembly tool 3 must be used to expand the clip plate 200 so that the protrusion 10 on the male connector 1 can be pulled out from the groove 210. This utility model is highly efficient and convenient to use. It is needed whenever there is a need to insert and remove the plug, whether for testing or trial assembly. This is because it will not scrap the product.

[0035] In practice, simply insert the disassembly tool 3 into the hole of the female connector 2 along the male connector 1 to easily separate the pipe connector. The entire process is simple and easy to learn, requiring no complex tools or cumbersome procedures, greatly saving operation time and labor costs, and effectively improving work efficiency. Whether it is frequent plugging and unplugging tests in experimental scenarios or temporary adjustments to pipe connector connections during trial assembly, it can quickly respond to needs and reduce equipment downtime and waiting time.

[0036] Traditional pipe connector disassembly methods often damage the plug or connected products, leading to component failure and increased maintenance and replacement costs. This invention, however, cleverly designs a mechanism for the disassembly tool 3 to engage with the internal clip 20 of the female connector 2. The disassembly tool 3 expands the clip 20 to allow the male connector 1 to be easily pulled out, avoiding physical damage to the pipe connector caused by forced disassembly. This ensures the product can be reused multiple times and significantly reduces material waste and economic losses caused by disassembly.

[0037] The female connector 2 is subdivided into a locking section 21, a connecting section 22, and an inserting section 23, each with a clearly defined function. The inner diameter of the connecting section 22 is smaller than that of the locking section 21, and the inner diameter of the inserting section 23 is smaller than that of the connecting section 22. This stepped structural design [as shown in the structure of the female connector 2] not only helps to stabilize the position of the male plug 1 when it is inserted, but also forms an effective seal and buffer at the connection of different pipe diameters. The locking section 21 is equipped with a clip 20 and a groove 210 to precisely control the insertion and removal state of the male plug 1. The expansion groove 201 on the clip 20 cleverly realizes the deformation under force, which facilitates the coordinated work with the removal tool 3. The multiple annular grooves 220 provided in the connecting section 22 further enhance the friction and stability of the connection between the female connector 2 and the external accessories, preventing accidental loosening.

[0038] The unique design of the clamp plate 200 in the clip 20, including the inclined surface 202, the curved surface 203, the turning surface 204, and the slope surface 205, is ingenious. The inclined surface 202 facilitates the smooth insertion of the male plug 1, reducing insertion resistance; the curved surface 203 conforms to the contour of the protrusion 10 of the male plug 1, ensuring a stable connection; the turning surface 204 strengthens the overall structural strength of the clamp plate 200; and the slope surface 205 optimizes the transition effect during insertion. The cooperation of each surface makes the plug insertion and removal process smooth and reduces jamming and wear.

[0039] Multiple sets of connecting protrusions 230 on the outside of the embedded section 23 [based on the structural design of the embedded section 23] can be firmly inserted into the inside of the pipe, which enhances the reliability of the connection between the female connector 2 and the pipe, effectively prevents liquid and gas leakage, ensures good sealing of the pipeline system, and maintains stable system operation.

[0040] The locking section 21 is equipped with a protective sleeve 211. This thoughtful design can prevent damage to the locking section 21 due to accidental collisions or scratches during daily handling, installation, and plugging / unplugging operations, maintain the integrity of the internal structure of the female connector 2, and extend its service life. At the same time, it can also prevent operators from accidentally touching sharp edges and corners and causing personal injury, thus improving operational safety.

[0041] This invention enables non-destructive insertion and removal, and is simple and efficient to operate, making it unrestricted by specific industries or scenarios. Whether it's the frequent debugging of small pipe joints on various instruments and equipment in scientific research laboratories, the temporary assembly and disassembly of a large number of pipe components during the trial production stage of automobile manufacturing and industrial production lines, or the maintenance of delicate internal pipelines in electronic products, it can perfectly adapt to any situation involving repeated insertion and removal of pipe joints, demonstrating extremely strong versatility.
