Understandably, the locking member 3 can also be disposed on both the male end joint 2 and the female end joint 1 simultaneously. When the plug-in section 22 of the male end joint 2 is plugged into the socket section 12 of the female end joint 1, the locking member 3 can lock the female end joint 1 and the male end joint 2 together, thereby enabling the rapid installation and connection of two pipes. When the locking of the male end joint 2 or the female end joint 1 by the locking member 3 is released, the plug-in section 22 of the male end joint 2 and the socket section 12 of the female end joint 1 can be quickly disassembled and separated, thereby enabling the rapid disconnection of two pipes.

[0037] The socket joint provided by the embodiment of the utility model, compared with the prior art, when it is necessary to install and connect two pipes, only the insertion section 22 of the male end joint 2 needs to be inserted into the socket section 12 of the female end joint 1, and then the male end joint 2 and / or the female end joint 1 is locked by the locking member 3 to lock the female end joint 1 and the male end joint 2 together, so as to realize the quick installation and connection of two pipes. When it is necessary to disassemble and disconnect two pipes, when the locking of the male end joint 2 and / or the female end joint 1 is released only through the locking member 3, the insertion section 22 of the male end joint 2 and the socket section 12 of the female end joint 1 can be quickly disassembled and separated, so as to realize the quick disassembly and disconnection of two pipes. Since the installation and disassembly of the above socket joint do not require the aid of complex professional tools, the difficulty of pipe installation and disassembly is reduced, the operation is simple, time-saving and labor-saving, and the pipes can be connected and disassembled on a large scale quickly and efficiently, greatly improving the work efficiency and being beneficial to reducing the installation and maintenance costs of pipes.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the locking member 3 is a spring clamp. The spring clamp is sleeved on the female end joint 1 and the male end joint 2. Only by locking the female end joint 1 and the male end joint 2 together through the spring clamp can the quick installation and connection of two pipes be realized. It should be noted that the spring clamp can also be sleeved on the female end joint 1 or the male end joint 2. When the spring clamp is sleeved on the female end joint 1, the male end joint 2 can be locked to the female end joint 1 through the spring clamp, so as to realize locking the female end joint 1 and the male end joint 2 together through the spring clamp. When the spring clamp is sleeved on the male end joint 2, the female end joint 1 can be locked to the male end joint 2 through the spring clamp, so as to realize locking the female end joint 1 and the male end joint 2 together through the spring clamp.

[0039] It can be understood that in some other embodiments, the locking member 3 is an internal thread sleeve. A first external thread is provided on the outer peripheral surface of the female end joint 1 near the male end joint 2, and a second external thread is provided on the outer peripheral surface of the male end joint 2 near the female end joint 1. The internal thread sleeve is screwed onto the first external thread and / or the second external thread. When the internal thread sleeve is simultaneously screwed onto the first external thread on the female end joint 1 and the second external thread on the male end joint 2, the female end joint 1 and the male end joint 2 can be locked together through the internal thread sleeve.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 4, in some embodiments, a first clamping structure 13 is provided on the outer peripheral surface of the female end joint 1, and a second clamping structure 23 is provided on the outer peripheral surface of the male end joint 2. The locking member 3 is a spring clip. At positions corresponding to the first clamping structure 13 and the second clamping structure 23 on the spring clip, a first hole groove structure 311 and a second hole groove structure 312 are respectively provided. When the spring clip locks the female end joint 1 and the male end joint 2 together, the first clamping structure 13 on the female end joint 1 is clamped in the first hole groove structure 311 on the spring clip, and the second clamping structure 23 on the male end joint 2 is clamped in the second hole groove structure 312 on the spring clip, which can improve the locking connection strength of the spring clip to the female end joint 1 and the male end joint 2, and effectively prevent the female end joint 1 and the male end joint 2 from slipping when subjected to axial tension. Therefore, when the female end joint 1 and the male end joint 2 are under a certain pressure and tension, they will not loosen or fall off easily, which is particularly important for some occasions with high requirements for connection stability, such as fluid transportation, chemical pipelines, etc.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments, the first clamping structure 13 can be, but is not limited to, a first annular protrusion protruding from the outer peripheral surface of the female end joint 1, and the first hole groove structure 311 can be, but is not limited to, a first annular limiting hole or a first annular groove provided on the spring clip. Similarly, the second clamping structure 23 can be, but is not limited to, a second annular protrusion protruding from the outer peripheral surface of the male end joint 2, and the second hole groove structure 312 can be, but is not limited to, a second annular limiting hole or a second annular groove opened on the spring clip.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments, the spring clip includes a ring-shaped clip body 31 made of an elastic material, a first retaining ear 32 provided at one end of the clip body 31, and a second retaining ear 33 provided at the other end of the clip body 31. The first hole groove structure 311 and the second hole groove structure 312 are opened on the clip body 31. The operator only needs to pinch the first retaining ear 32 and the second retaining ear 33 at both ends of the clip body 31 to realize the installation and disassembly of the spring clip. Without the aid of complex special tools, the socket joint can be quickly installed and disassembled, and ordinary operators can also easily complete it, which makes the on-site operation more convenient and reduces the requirements for the operator's skill level.

[0043] Please refer to Figure 1 、 Figure 2 and Figure 3, in some of these embodiments, the part of the clamp body 31 located between the first hole groove structure 311 and the second hole groove structure 312 forms an occlusion part 313. The occlusion part 313 is sleeved on the connection part of the female end joint 1 and the male end joint 2, so that the occlusion part 313 can occlude the connection seam between the female end joint 1 and the male end joint 2. On the one hand, it can prevent external foreign objects from entering the inside of the socket joint through the connection seam between the female end joint 1 and the male end joint 2. On the other hand, it can provide reliable connection strength to the female end joint 1 and the male end joint 2.

[0044] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some of these embodiments, the socket joint further includes at least one sealing ring 4 provided between the insertion section 22 and the socket section 12. The insertion section 22 and / or the socket section 12 are provided with sealing grooves 5 for positioning and installing the sealing ring 4. Specifically, a multi-layer sealing structure using 3-layer O-ring seals 4 can effectively prevent fluid leakage. Whether it is liquid or gas, it can ensure that there is no leakage at the connection part of the socket joint, guaranteeing the normal operation of the system.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 4 , in some of these embodiments, in order to further improve the sealing performance of the connection part of the socket joint, the number of the sealing rings 4 is set to be multiple, and the multiple sealing rings 4 are arranged at intervals along the axial direction of the insertion section 22.

[0046] Please refer to Figure 2 and Figure 4 , in some of these embodiments, the socket section 12 is provided with a first limit step 6 for abutting against the corresponding end of the insertion section 22, and the insertion section 22 is provided with a second limit step 7 for abutting against the corresponding end of the socket section 12. When the insertion section 22 of the male end joint 2 is inserted into the socket section 12 of the female end joint 1, the first limit step 6 plays a role of abutting and limiting the corresponding end of the insertion section 22. At the same time, the second limit step 7 plays a role of abutting and limiting the corresponding end of the socket section 12. On the one hand, it can enable the female end joint 1 and the male end joint 2 to withstand a certain axial pressure and not loosen easily. On the other hand, it can enhance the connection strength and stability between the socket section 12 and the insertion section 22.

[0047] The embodiments of the present utility model also provide a pipeline system, which includes the socket joint provided in any of the above embodiments. Since the pipeline system has all the technical features of the socket joint provided in any of the above embodiments, it has the same technical effects as the above socket joint.
