A fixing screw is fixedly connected to the upper surface of the threaded rod, and a threaded hole is threadedly connected to the lower surface of the fixing screw. This water pipe connector, by setting the fixing screw to drive the threaded rod to rotate inside the threaded hole, can thread the fixing ring and the connecting ring together, which increases the stability of the product when the water pipe is increased or the length is extended. By applying an anti-rust coating to the connecting pipe, the corrosion and rust caused by water flow to the inner wall of the equipment can be reduced during long-term use, increasing the service life of the connecting pipe and reducing production costs.

[0004] This device uses a connecting ring with a threaded inner wall to connect water pipes to the product during installation. However, this method of connecting water pipes via threaded connection is slow, and the threads are prone to corrosion during long-term use, which affects the firmness of the connection and results in insufficient sealing of the water pipe connection on both sides.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing quick-connect double-compression fitting structure for water pipes. Utility Model Content

[0006] The purpose of this invention is to provide a water pipe connector that can quickly connect to a double compression fitting, in order to solve the problems mentioned in the background art, such as the slow efficiency of connecting and installing water pipes through threaded connection, and the fact that the thread is easily corroded during long-term use, thus affecting the firmness of the connection and causing insufficient sealing of the water pipe connection on both sides.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water pipe connector with a quick-connect double-clamp sleeve, comprising a butt joint fixedly connected to both ends of a pipe body; an inner sleeve fixedly connected to the inside of the butt joint; a butt assembly disposed on the connecting pipe, the connecting pipe and the pipe body being on the same pipeline axis, the butt assembly being used to connect the butt joint; and a fastening assembly movably disposed on the butt assembly, the fastening assembly being used to fasten the butt joint, wherein when the connecting pipe connects to the pipe body, the butt joint and the inner sleeve move toward the butt assembly and the fastening assembly, so that the butt joint respectively engages with the butt assembly and fastens the fastening assembly.

[0008] Preferably, the docking assembly includes a sliding rod, a limiting block, and a first telescopic spring. The sliding rod is slidably connected to the inner side of the docking joint, the limiting block is fixedly connected to the tail end of the sliding rod, and the limiting block is shaped like a slanted trapezoid when viewed from the side. The first telescopic spring is connected between the limiting block and the inner wall of the docking joint.

[0009] Preferably, the limiting blocks are arranged in four sets at equal angles with respect to the center of the joint.

[0010] Preferably, the docking assembly further includes a connector, a plug, and a sealing ring. The connector is connected to the outside of the docking head, the plug is fixedly connected to the outside of the connector, the sealing ring is fixedly connected to the inner ring of the plug, and the plug is nested on the outside of the inner sleeve. The outside of the connector is fixedly connected to the connecting tube.

[0011] Preferably, the diameter of the plug is larger than the diameter of the inner sleeve, and the diameter of the plug is smaller than the diameter of the connector.

[0012] Preferably, the fastening assembly includes a first cover plate, a second cover plate, and a through groove. The first cover plate is rotatably connected to the outside of the connector, and the second cover plate is rotatably connected to the outside of the connector. The through groove is formed at both ends of the first cover plate and the second cover plate.

[0013] Preferably, the fastening assembly further includes a connecting plate, a second telescopic spring, and a locking rod. The connecting plate is fixedly connected to the outside of the first cover plate, one end of the second telescopic spring is connected to the connecting plate, and the other end of the second telescopic spring is connected to the tail end of the locking rod, with the locking rod penetrating through the inside of the connecting plate.

[0014] Preferably, the fastening assembly further includes a notch and a slot, the notch being formed in the second cover plate and the slot being formed within the notch;

[0015] The slot can engage with the connecting rod.

[0016] Compared with the prior art, the beneficial effect of this utility model is that the quick-connect double-compression fitting water pipe connector is provided with:

[0017] 1. The quick-connect structure allows for the connection of water pipes on both sides. First, the connector and the fitting are placed on the same horizontal plane. Then, the plug is pushed inward along the inner side of the connector. During this sliding process, the outer wall of the plug pushes the limiting block outward and compresses the first telescopic spring. As the plug goes deeper, the distance the limiting block moves outward increases, and the elasticity of the first telescopic spring also increases until the plug is completely fitted onto the outer side of the inner sleeve. At this point, the sealing ring between the inner wall of the plug and the inner sleeve prevents liquid leakage from the connection between the plug and the inner sleeve. The limiting block is also tightly fitted to the outer side of the plug by the elasticity of the first telescopic spring, thus connecting the connector and the fitting together and allowing the water pipes on both sides to be used in parallel. This structure not only has high connection efficiency but also ensures good sealing between the connector and the fitting.

[0018] 2. Anti-loosening structure: After the connector and joint are assembled, manually pull the lever outward, then rotate the first and second cover plates on both sides to make them rotate 90° and fit together. After fitting together, release the lever, and the lever will reset due to the elasticity of the second telescopic spring, so that the tail end of the lever engages with the groove on the inner side of the second cover plate. The engagement of the tail end of the lever with the groove fixes the first and second cover plates on both sides. The fixation of the first and second cover plates prevents the connector and joint from being subjected to large tensile forces, thus preventing separation or loosening and improving the assembly stability of the connector and joint.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a water pipe connector with quick-connect double compression fittings, comprising:

[0028] Example 1: As Figures 1-4 The present invention provides a technical solution: a water pipe connector with a quick-connect double compression fitting, comprising: a butt joint 2, which is fixedly connected to both ends of a pipe body 1; an inner sleeve 3, which is fixedly connected to the inside of the butt joint 2; and a butt assembly 4, which is disposed on a connecting pipe 405, wherein the connecting pipe 405 and the pipe body 1 are on the same pipeline axis, and the butt assembly 4 is used to connect the butt joint 2.

[0029] Fastening component 5 is movably mounted on docking component 4. Fastening component 5 is used to fasten connector 2. When connecting pipe 405 is connected to pipe body 1, connector 2 and inner sleeve 3 move toward docking component 4 and fastening component 5 so that connector 2 respectively engages docking component 4 and fastening component 5.

[0030] The docking assembly 4 includes a sliding rod 401, a limiting block 402, and a first telescopic spring 403. The sliding rod 401 is slidably connected to the inner side of the docking joint 2. The limiting block 402 is fixedly connected to the tail end of the sliding rod 401, and the limiting block 402 is shaped like a slanted trapezoid when viewed from the side. The first telescopic spring 403 is connected between the limiting block 402 and the inner wall of the docking joint 2. The limiting block 402 is provided with four sets of equal angles about the center of the docking joint 2. The docking assembly 4 also includes a connector 404, a plug 406, and a sealing ring 407. The connector 404 is connected to the outer side of the docking joint 2. The plug 406 is fixedly connected to the outer side of the connector 404. The sealing ring 407 is fixedly connected to the inner ring of the plug 406, and the plug 406 is nested on the outer side of the inner sleeve 3. The outer side of the connector 404 is fixedly connected to the connecting tube 405. The diameter of the plug 406 is larger than the diameter of the inner sleeve 3 and smaller than the diameter of the docking joint 2.

[0031] The connecting pipe 405 and the pipe body 1 are the same size water pipes, and the connecting pipe 405 is fixedly connected to the outside of the connector 404. When it is necessary to connect the water pipes on both sides, first place the connector 2 and the connector 404 on the same horizontal plane, and then push the plug 406 inward along the inner wall of the connector 2. During the sliding process, the outer wall of the plug 406 will push the limiting block 402 outward and compress the first telescopic spring 403. As the plug 406 goes deeper, the distance that the limiting block 402 moves outward increases, and the first telescopic spring 403... The greater the elasticity, the more the plug 406 fits completely onto the outside of the inner sleeve 3. At this point, the sealing ring 407 between the inner wall of the plug 406 and the inner sleeve 3 can prevent liquid from leaking from the connection between the plug 406 and the inner sleeve 3. The limiting block 402 will also fit tightly against the outside of the plug 406 by the elasticity of the first telescopic spring 403, thereby connecting the connector 2 and the connector 404 together and connecting the water pipes on both sides in parallel. This structure not only has high docking efficiency, but also ensures good sealing between the connector 2 and the connector 404.

[0032] Example 2: Figures 1-2 , Figures 5-6The present invention provides a technical solution: a water pipe connector with a quick-connect double-clamp sleeve, which discloses that: the fastening assembly 5 includes a first cover plate 501, a second cover plate 502, and a through groove 503. The first cover plate 501 is rotatably connected to the outside of the connector 404, and the second cover plate 502 is rotatably connected to the outside of the connector 404. The through groove 503 is formed at both ends of the first cover plate 501 and the second cover plate 502. The fastening assembly 5 also includes a connecting plate 504 and a second telescopic spring. The fastening assembly 5 also includes a notch 507 and a slot 508. The notch 507 is opened on the second cover plate 502, and the slot 508 is opened inside the notch 507. The slot 508 can engage with the clamping rod 506.

[0033] After the connector 2 and connector 404 are assembled, the locking rod 506 is manually pulled outward. Then, the first cover plate 501 and the second cover plate 502 on both sides are rotated 90° to fit together. After fitting together, the locking rod 506 is released. The locking rod 506 is reset by the elastic force of the second telescopic spring 505, so that the tail end of the locking rod 506 engages with the slot 508 on the inner side of the second cover plate 502. The engagement of the tail end of the locking rod 506 with the slot 508 fixes the first cover plate 501 and the second cover plate 502 on both sides. The fixation of the first cover plate 501 and the second cover plate 502 prevents the connector 2 and connector 404 from being subjected to large pulling forces, thus improving the assembly stability of the connector 2 and connector 404.
