Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quick coupling technology, and in particular relates to a high-pressure resistant quick coupling. Background Technology
[0002] Quick couplings are efficient and convenient pipe connection devices that can connect or disconnect pipes without the use of tools. They are used in pipes, hoses, or other fluid transfer systems, but they have the following drawbacks:
[0003] 1. Some existing quick couplings have poor sealing and high-pressure resistance at the connection point. When the pressure at the connection point is too high, leakage may occur. They may not be able to provide sufficient sealing force under high pressure, which makes them not very practical.
[0004] 2. At the same time, some quick couplings are not convenient for intercepting the liquid in the pipeline when disassembling, and cannot automatically cut off the fluid flow when disassembling.
[0005] Therefore, we propose a high-pressure resistant quick connector. Utility Model Content
[0006] The purpose of this invention is to address the problems of existing quick couplings, such as poor sealing and high-pressure resistance at the connection point, potential leakage under excessive pressure, and insufficient sealing force under high pressure, which reduces their practicality. Additionally, some quick couplings are not convenient for intercepting liquid in the pipeline during disassembly and cannot automatically cut off fluid flow. Therefore, this invention proposes a high-pressure resistant quick coupling.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A high-pressure resistant quick coupling includes:
[0009] A male connector and a female connector are provided. The outer wall of the male connector is slidably fitted with a sleeve. The front end of the sleeve is provided with an internal thread groove. The outer wall of the rear end of the female connector is provided with an external thread block. The sleeve and the female connector are threadedly connected through the external thread block and the internal thread groove, which is used to connect the male connector and the female connector.
[0010] A sealing assembly includes a positioning plate fixedly installed on the inner wall of the female connector. An annular cylinder is fixedly connected to the outer wall of the rear end of the positioning plate. A limiting sleeve is fixedly connected to the outer wall of the front end of the male connector. The limiting sleeve is slidably sleeved on the outer wall of the annular cylinder. A first sealing ring is provided at the rear end of the inner wall of the limiting sleeve to improve the high pressure resistance of the connection between the male and female connectors.
[0011] The flow-stopping component is designed to be installed inside the female connector to control fluid flow when the male and female connectors are separated.
[0012] In one possible design, the flow-stopping assembly includes support rods fixedly mounted on the upper, lower, and sides of the positioning plate, with positioning frames slidably connected to the outer walls of the support rods, and baffles fixedly connected to the middle of the positioning frames for sealing the positioning plate.
[0013] In one possible design, multiple positioning frames pass through the positioning plate and are fixedly connected to a push plate, and springs are slidably sleeved on the outer walls of multiple support rods, with a second sealing ring provided at the rear end of the push plate.
[0014] In one possible design, the outer wall of the front end of the male connector is fixedly connected with multiple guide rods, and the outer wall of the rear end of the female connector is provided with multiple guide holes. The guide rods are slidably connected to the guide holes to enable the male and female connectors to be installed stably.
[0015] In one possible design, the outer wall of the guide rod is fitted with a sealing gasket.
[0016] In one possible design, both the outer walls of the female connector and the sleeve are provided with an anti-slip layer.
[0017] In this application, when connecting pipelines, first align the male and female connectors, ensuring the guide rod is aligned with the guide hole. Manually rotate the sleeve to connect it to the external threaded block at the rear end of the female connector. Push the male connector into the female connector, allowing the guide rod to slide along the guide hole, ensuring stable installation of the male and female connectors. Simultaneously, as the male connector is pushed in, the limiting sleeve slides along the outer wall of the annular cylinder until it reaches the preset position. At this point, the first sealing ring is compressed and tightly adheres to the outer wall of the annular cylinder, forming a sealing barrier to effectively prevent high-pressure fluid from leaking from the connection. At the same time, the limiting sleeve pushes the push plate to open the baffle, allowing the flow-stopping component to be opened. When disassembling the pipeline, first rotate the sleeve to disconnect it from the external threaded block at the rear end of the female connector, allowing the guide rod to slide along the guide hole until the male connector is completely disengaged from the female connector. During this process, the flow-stopping component is automatically activated by the spring, sealing the positioning plate through the baffle to effectively prevent fluid from flowing out during disassembly.
[0018] In this utility model, the high-pressure resistant quick connector, through the combined design of a first sealing ring and an annular cylinder, as well as the guiding effect of the guide rod and guide hole, forms multiple sealing barriers at the connection point, effectively improving its high-pressure resistance performance. Even under high-pressure environments, it can ensure the stability and safety of the connection point and avoid leakage. At the same time, the quick connector adopts a threaded connection and guide design, which allows for quick connection and disassembly between the male and female connectors without the need for tools, greatly improving work efficiency.
[0019] In this utility model, a high-pressure resistant quick connector is provided. During disassembly, the flow-stopping component automatically activates, and the baffle is pushed by a spring to seal the positioning plate, effectively preventing fluid leakage. At the same time, by adopting a multi-layer sealing barrier design, this high-pressure resistant quick connector has high stability and safety at the connection point, ensuring the normal operation of the pipeline even in harsh working environments.

[0032] Male connector 1 and female connector 2. A sleeve 3 is slidably fitted on the outer wall of male connector 1. An internal thread groove 4 is opened at the front end of sleeve 3. An external thread block 5 is provided on the outer wall of the rear end of female connector 2. Sleeve 3 and female connector 2 are threadedly connected by external thread block 5 and internal thread groove 4, which is used to connect male connector 1 and female connector 2.
[0033] The sealing assembly includes a positioning plate 12 fixedly installed on the inner wall of the female connector 2. An annular cylinder 7 is fixedly connected to the outer wall of the rear end of the positioning plate 12. A limiting sleeve 6 is fixedly connected to the outer wall of the front end of the male connector 1. The limiting sleeve 6 is slidably sleeved on the outer wall of the annular cylinder 7.

[0034] The flow-stopping component is designed to be installed inside the female connector 2 to control fluid from flowing out when the male connector 1 and the female connector 2 are separated.
[0035] In the above technical solution, the male connector 1 and the female connector 2 are connected by the internal thread groove 4 on the sleeve 3 to the external thread block 5 at the rear end of the female connector 2, thereby achieving the connection between the two.

[0039] In the above technical solution, by setting a second sealing ring 18, the limiting sleeve 6 can be tightly fitted with the second sealing ring 18, which can improve the sealing performance of the quick connector.
[0040] This application can be used in the field of quick connectors, or in other fields applicable to this application.
