Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a reusable pipeline quick connector. Background Art

[0002] A pipe connector is a device used to connect pipes, primarily used in fluid and gas pipelines, providing connection, fixing, and sealing functions. Existing pipe connectors typically connect and seal the pipes by squeezing a sealing sleeve through a pressing block. However, the sealing sleeve can become sticky due to dust and impurities adhering to its exterior during use. This buildup over time can cause the sealing sleeve to become sticky, which can cause the sealing sleeve to adhere to the inside of the device during disassembly, making it difficult to remove and making the device inconvenient for reuse.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A reusable pipe quick connector includes: a short tube 1, a sealing sleeve 2, a nut 3 and an annular pressure plate 4. The short tube 1 can facilitate the insertion of the pipe, the sealing sleeve 2 can seal the pipe, the nut 3 and the annular pressure plate 4 can drive the sealing sleeve 2 to tighten the pipe, the sealing sleeve 2 is assembled at both ends inside the short tube 1, and the nut 3 is threadedly connected to both ends of the short tube 1.

[0024] The annular pressure plate 4 is connected to the nut 3, and the outside of the short tube 1 and the nut 3 are respectively sleeved with a first sleeve 11 and a second sleeve 31, and the outside of the first sleeve 11 and the second sleeve 31 are provided with anti-slip grooves. The first sleeve 11 and the second sleeve 31 are convenient for the staff to fix the short tube 1 and the nut 3. Both ends of the interior of the short tube 1 are connected with an annular baffle 12, and the sealing sleeve 2 is slidably connected to the annular baffle 12. The annular baffle 12 can limit and guide the sealing sleeve 2.

[0025] See also Figure 3 、 Figure 4 and Figure 5 The two ends of the short tube 1 are respectively connected to a pushing mechanism 5, which includes a push plate 51. The push plate 51 can drive the sealing sleeve 2 to move and scrape the inner wall of the short tube 1. The push plate 51 is slidably connected to the short tube 1. The outside of the push plate 51 is evenly distributed with a first piston rod 52, which can drive the push plate 51 to move.

[0026] The outside of the first piston rod 52 is slidably connected to a curved cylinder 53, and the curved cylinder 53 is connected to the short tube 1. The inside of the curved cylinder 53 is slidably connected to the second piston rod 54. The movement of the second piston rod 54 inside the curved cylinder 53 can drive the first piston rod 52 to move, and a spring 55 is connected between the second piston rod 54 and the curved cylinder 53. A trapezoidal groove 32 is opened inside the nut 3, and the two ends of the trapezoidal groove 32 are designed with bevel edges. The trapezoidal groove 32 can accommodate the second piston rod 54 to prevent the second piston rod 54 from continuing to move. The second piston rod 54 and the first piston rod 52 are both embedded with guide plates 56, and the guide plates 56 are slidably connected to the inside of the curved cylinder 53. The guide plates 56 can guide the second piston rod 54 and the first piston rod 52 to move linearly. The outer ends of the second piston rod 54 are both designed with bevels, and the outer ends of the second piston rod 54 are adapted to the inner part of the trapezoidal groove 32, so that the second piston rod 54 can be moved by the trapezoidal groove 32.

[0027] In this solution, two nuts 3 are first sleeved inside the short tube 1, and the pipe is inserted into the inside of the short tube 1 and the outside of the annular baffle 12. The nuts 3 are rotated outside the short tube 1 to move, thereby driving the annular pressure plate 4 to move, thereby squeezing the sealing sleeve 2 so that the sealing sleeve 2 fixes and seals the pipe inside the short tube 1 to complete the sealing of the two pipes.

[0028] When the nut 3 moves, it will first squeeze the second piston rod 54 to move, and then the second piston rod 54 will be inserted into the trapezoidal groove 32 for storage. When the pipeline needs to be disconnected, the trapezoidal groove 32 is rotated in the opposite direction and taken out from the outside of the short tube 1. When it is taken out, the trapezoidal groove 32 will squeeze the second piston rod 54, causing the second piston rod 54 to retract into the inside of the curved tube 53 to generate pressure. The pressure drives the first piston rod 52 to move, and then drives the push plate 51 to move, pushing the sealing sleeve 2 and scraping the inside of the short tube 1.

[0029] When the device is disassembled for reuse, the added nut 3 drives the pushing mechanism 5 to move, thereby driving the sealing sleeve 2 to prevent dust and impurities from adhering to the outside of the sealing sleeve 2 and depositing for a long time, causing the sealing sleeve 2 to become sticky, thereby preventing the sealing sleeve 2 from adhering to the inside of the device and becoming difficult to remove. At the same time, the pushing mechanism 5 will also scrape the inside of the short tube 1 during movement, thereby preventing debris of the sealing sleeve 2 from adhering to the inside of the short tube 1, causing the subsequent new sealing sleeve 2 to be unable to fit with the device and reduce the overall sealing performance of the short tube 1.
