Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, specifically a quick pipe fitting assembly. Background Technology

[0002] Quick-connect pipe assemblies are devices used to quickly connect and disconnect pipes without the need for complicated tools or cumbersome operations. They offer advantages such as high efficiency, convenience, and reliable sealing, and are widely used in various fluid transport systems.

[0003] Existing patent document CN218992696U discloses a quick-connect assembly for an alcohol-based fuel pipeline, comprising a male and a female connector, which are fixedly connected by a connecting assembly. Each of the male and female connectors has a connecting head fixedly connected to one side for connecting to the alcohol-based fuel pipeline. The advantages of this invention are: after disassembling the connector assembly, i.e., when separating the male and female connectors, the push rod is pulled out from the through hole, causing the sealing plate to abut against one side of the baffle under the elastic action of the spring, thereby sealing the through hole and closing the female connector. In other words, after separating the male and female connectors, the female connector can be closed, thus preventing the alcohol-based liquid fuel from leaking from the pipeline. The feed switch does not need to be turned off when separating the connector assembly, making it quick and convenient for practical use.

[0004] However, existing quick-connect pipe fittings, while capable of quickly separating male and female connectors, require clamps or other methods for installation, which complicates the process and reduces efficiency. To address this, we propose a quick-connect pipe fitting assembly. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a quick-connect pipe assembly, which has the following advantages:

[0016] (1) This type of quick pipe connector assembly, through the setting of nut sleeve, compression ring and fixing ring, when using the pipe connector, when it is necessary to connect the pipe connector to the pipe, the worker inserts the pipe plug into the pipe, and the pipe will press against the sealing ring. At the same time, the anti-detachment ring can play a role in preventing detachment. Then the worker rotates the nut sleeve clockwise, and the nut sleeve moves towards the fixing ring. At this time, the compression ring of the nut sleeve squeezes the fixing ring, and the fixing ring will shrink through the through groove after being squeezed. At this time, the fixing ring can fix the pipe, and the pipe can be connected. When it is necessary to separate the pipe, the worker rotates the connecting nut counterclockwise, and the connecting nut disengages from the threaded ring. At this time, the male and female can be separated. This method simplifies the installation steps and thus improves the installation efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a quick pipe connector assembly, including a male connector 1 and a female connector 8. Both the male connector 1 and the female connector 8 are threadedly connected to a nut sleeve 2 on their outer sides. A compression ring 3 is installed on the inner side of the nut sleeve 2. One end of both the male connector 1 and the female connector 8 is integrally formed with a shrink tube 4 and a pipe plug 7. One end of the shrink tube 4 is integrally formed with a fixing ring 5. Both the shrink tube 4 and the fixing ring 5 have through grooves 6 on their outer sides. The other end of the male connector 1 is integrally formed with a limiting ring 101 on its outer side. A connecting nut 9 is movably connected to the outer side of the limiting ring 101. The other end of the female connector 8 is integrally formed with a threaded ring 801 on its outer side.

[0024] Furthermore, an anti-detachment ring 701 is integrally formed on the outer side of the pipe plug 7. The anti-detachment ring 701 gradually decreases in size from left to right. The anti-detachment ring 701 can prevent the pipe installed on the pipe plug 7 from falling off.

[0025] Furthermore, a sealing ring 10 is installed on the inner side of the shrink tube 4. The sealing ring 10 is made of rubber material and can play a sealing role to prevent water leakage.

[0026] Furthermore, the diameter of the threaded ring 801 is matched with the inner diameter of the connecting nut 9. The threaded ring 801 is threadedly connected to the connecting nut 9. By rotating the connecting nut 9 counterclockwise, the connecting nut 9 disengages from the threaded ring 801. At this time, the male head 1 and the female head 8 can be separated. During assembly, the connecting nut 9 is threadedly connected to the threaded ring 801, and the male head 1 and the female head 8 can be combined.

[0027] Furthermore, both the male head 1 and the female head 8 have a cylindrical structure, and the interior of the male head 1 and the female head 8 is hollowed out, allowing the liquid to flow inside the male head 1 and the female head 8.

[0028] Furthermore, there are two pipe plugs 7, both of the same size and symmetrically arranged. When the pipe plugs 7 are inserted into the pipe, the pipe will press against the sealing ring 10, thus achieving the function of connecting the pipe.

[0029] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the pipe connector, when it is necessary to connect the pipe connector to the pipe, the worker inserts the pipe plug 7 into the pipe, and the pipe will press against the sealing ring 10. At the same time, the anti-detachment ring 701 can play a role in preventing detachment. Then, the worker rotates the nut sleeve 2 clockwise, and the nut sleeve 2 moves towards the fixing ring 5. At this time, the nut sleeve 2 squeezes the ring 3 and the fixing ring 5. After being squeezed, the fixing ring 5 will shrink through the through groove 6, and the fixing ring 5 can fix the pipe. At this time, the pipe can be connected. When it is necessary to separate the pipe, the worker rotates the connecting nut 9 counterclockwise, and the connecting nut 9 disengages from the threaded ring 801. At this time, the male head 1 and the female head 8 can be separated. During assembly, the connecting nut 9 is threadedly connected to the threaded ring 801, and the male head 1 and the female head 8 can be merged. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
