Description

Technical Field

[0001] The invention belongs to the technical field of automobile pipelines, and in particular relates to a pipe joint connection remover. Background Art

[0002] In many industrial fields and various complex engineering systems today, pipe fittings are key components that connect various pipelines and ensure smooth medium transmission. They are widely used in many industries such as automobile manufacturing, aerospace, chemical production, and electronic equipment cooling systems. However, the existing pipe fitting connection and disassembly technology has a series of thorny problems that need to be solved urgently.

[0003] Most traditional pipe joint connection methods rely on simple plug-in and pull-out to lock strongly, or use threaded rotation and tightening to achieve a stable connection. The disadvantages of this type of conventional connection method are obvious during disassembly: on the one hand, strong plug-in or twisting operations can easily cause the pipe joint itself to wear, deform, or even break and become scrapped. For example, in the maintenance scene of the cooling pipes around the automobile engine, maintenance personnel often need to use a large external force to pry out the old pipe joints. If they are not careful, the metal pipe joints will be damaged such as thread stripping and pipe wall dents. Not only will a single pipe joint be scrapped, but debris may also fall into the pipeline, causing more serious system failures, greatly increasing maintenance costs and time costs. Summary of the invention

[0030] Example

[0031] like Figure 1-Figure 6 As shown, the pipe joint connection remover includes a male plug 1, a female connector 2 and a remover 3. The male plug 1 is provided with a protrusion 10, and the female connector 2 is provided with a clip 20. The protrusion inside the male plug 1 passes through the clip 20 inside the female connector 2 for fixation. The remover 3 is inserted into the female connector 2 to expand the clip 20 so that the male plug 1 is pulled out. The female connector 2 includes a locking section 21, a connecting section 22, and an embedding section 23. The connecting section 22 is provided between the locking section 21 and the embedding 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 embedding section 23 is smaller than that of the connecting section 22.

[0032] The clip 20 is arranged inside the locking section 21, and a groove 210 is also provided on the locking section 21. The groove 210 is arranged on the inner side of the clip 20. The clip 20 includes a card plate 200 and an expansion groove 201. The card plate 200 is tilted toward the inner side of the locking section 21. The expansion groove 201 is arranged at the connection between the card plate 200 and the groove 210. The card plate 200 includes an inclined surface 202, an arcuate surface 203 and a turning surface 204. The arcuate surface 203 is arranged at the top of the inclined surface 202, and the turning surface 204 is arranged at both ends of the arcuate surface 203. A slope 205 is provided at the connection between the inclined surface 202 and the arcuate surface 203. A first sealing ring 231 is provided on the outside of the embedded 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 portion 32. The insertion portion 32 is fixedly connected to the handle 31, and the insertion portion 32 is semicircular.

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

[0034] When in use, the remover 3 is held by hand and inserted into the hole of the female connector 2 along the circle of the male plug 1. A non-detachable clip 20 is provided inside the female connector 2. The clip 20 can only be inserted but not removed. The remover 3 must be used to expand the card plate 200 so that the protrusion 10 on the male plug 1 can be partially withdrawn from the groove 210. The present invention is efficient and convenient to use. It is only needed for testing or test assembly, as long as the insertion and removal are required, because the product will not be scrapped.

[0035] In actual operation, you only need to hold the remover 3 and insert it into the hole of the female connector 2 along the male plug 1 to easily complete the separation operation of the pipe joint. The whole process is simple and easy to use, without the need for complex tools or cumbersome procedures, which greatly saves operation time and labor costs and effectively improves work efficiency. Whether it is frequent plug-in and unplug tests in test scenarios or temporary adjustments to pipe joint connections during test assembly, it can respond quickly to needs and reduce equipment downtime and waiting time.

[0036] Conventional pipe joint disassembly methods often easily damage the plug or the product connected thereto, causing the parts to be scrapped and increasing the cost of repair and replacement. However, the present invention cleverly designs the matching mechanism between the remover 3 and the internal clip 20 of the female connector 2, and uses the remover 3 to expand the clip 20 to smoothly pull out the male plug 1, thereby avoiding physical damage to the pipe joint caused by forced disassembly, ensuring that the product can be reused multiple times, and greatly reducing material loss and economic losses caused by disassembly.

[0037] The female connector 2 is subdivided into a locking section 21, a connecting section 22, and an embedding section 23, each of which has a clear division of labor. The inner diameter of the connecting section 22 is smaller than that of the locking section 21, and the inner diameter of the embedding 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] is not only conducive to stabilizing the position of the male plug 1 when inserted, but also can form an effective seal and buffer at the connection of different pipe diameters; the locking section 21 is provided with a clip 20 and a groove 210 to accurately control the plug-in and pull-out state of the male plug 1, and the expansion groove 201 on the clip 20 cleverly realizes force deformation, which is convenient for working with the remover 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 to prevent accidental loosening.

[0038] The unique design of the inclined surface 202, curved surface 203, turning surface 204 and slope surface 205 of the card plate 200 in the clip 20 is ingenious. The inclined surface 202 is conducive to guiding the male plug 1 when it is first inserted, reducing the insertion resistance; the curved surface 203 fits the contour of the protrusion 10 of the male plug 1 to ensure a stable connection; the turning surface 204 strengthens the overall structural strength of the card plate 200; the slope surface 205 optimizes the transition effect during insertion, and the various surfaces cooperate with each other to make the plug insertion and removal process smooth and reduce jamming and wear.

[0039] The multiple groups of connecting protrusions 230 outside the embedded section 23 [based on the structural design of the embedded section 23] can be firmly inserted into the inside of the pipe, thereby enhancing the reliability of the connection between the female connector 2 and the pipe, effectively preventing liquid and gas leakage, ensuring good sealing of the pipeline system, and maintaining stable operation of the system.

[0040] A protective cover 211 is provided on the outside of the locking section 21. This considerate design can prevent the locking section 21 from being damaged due to accidental collision or scratching during daily transportation, installation, and plugging and unplugging operations, thereby maintaining the internal structural integrity of the female connector 2 and extending its service life. At the same time, it can also prevent operators from accidentally touching sharp edges and causing personal injury, thereby improving operational safety.

[0041] The present invention can achieve lossless plugging and unplugging, and the operation is simple and efficient, so that it is not restricted by specific industries and scenarios. Whether it is the frequent debugging of small pipe joints on various instruments and equipment in scientific research laboratories, or the temporary assembly and disassembly of a large number of pipe fittings in the trial assembly stage of automobile manufacturing and industrial production lines, or the maintenance of fine pipelines inside electronic products, as long as it involves situations where pipe joints need to be repeatedly inserted and removed, it can be perfectly adapted and has strong versatility.
