Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to a leak-proof quick-connect coupling for pipeline connections. Background Technology

[0002] Pipe connection refers to connecting prefabricated pipe sections into a complete system according to the design drawings. During construction, different connection methods should be selected according to the material of the pipes used. Common steel pipes can be connected by threaded connections, flange connections, welding connections, socket connections, and pipe adhesive connections.

[0003] The patent disclosed in CN223120894U is a bidirectional pipe connector. This patent discloses a convenient connection technology solution, which solves the problem that when the existing bidirectional pipe connectors are in use, it is difficult to connect the two pipes by rotation when either the outer or inner pipe is already connected to the pipe system. Furthermore, when the diameter of the outer or inner pipe is large, rotation is also very laborious and troublesome.

[0004] When in use, the device facilitates docking through the setting of wedge block I and wedge block II, and can also prevent pipe I and pipe II from separating. However, the threaded connection is prone to stripping and rusting at the threaded connection due to interference from external factors, which reduces the effectiveness of use. Therefore, a leak-proof quick-connect coupling for pipe connection is proposed to solve the above problems. Utility Model Content

It solves the problem that existing couplings, when in use, are prone to threaded connections that are susceptible to external interference, leading to phenomena such as stripping and rusting at the threaded connection, thus reducing their effectiveness.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A leak-proof quick-connect fitting for pipe connections includes a mounting ring, on both the left and right sides of which a pipe extends into the ring at one end. A retaining ring is fixedly connected inside the mounting ring, and a sealing assembly for sealing the pipe is provided inside the mounting ring.

[0008] The sealing assembly includes two retaining rings, which are respectively fixedly fitted onto the outer peripheral walls of two pipes. Positioning grooves are provided on the left and right sides of the retaining rings. Two first rubber rings are fixedly connected inside each of the two positioning grooves. The two pipes extend into the two positioning grooves. Two second rubber rings are fixedly connected inside the mounting ring, and the pipes pass through the second rubber rings. Two mounting grooves are provided on the left and right sides of the mounting ring.

[0009] Each of the four mounting slots is equipped with a fixing component for securing the pipe.

[0010] Furthermore, the positioning groove is an annular groove, the pipe is located between two adjacent first rubber rings, and the outer peripheral wall of the fixing ring and the inner peripheral wall of the mounting ring are in contact.

[0011] Furthermore, both the first rubber ring and the second rubber ring are in contact with the pipe, with the second rubber ring located between the fixing ring and the mounting ring.

[0012] Furthermore, the fixing assembly includes a telescopic rod, which is fixedly connected inside the mounting groove. A movable plate is fixedly connected to the side of the telescopic rod near the fixing ring. Two fixing holes are formed on the top and bottom surfaces of both fixing rings. Two fixing rods, each extending into the fixing holes, are fixedly connected to the side of the movable plate near the fixing ring. Springs, respectively fixedly connected to the mounting groove and the movable plate, are fitted onto the outer periphery of the telescopic rod. Four sliding grooves are formed inside the mounting ring. A sliding plate, extending into the sliding groove, is fixedly connected to the side of the movable plate near the retaining ring. Rubber pads are fixedly connected to the front and back of the sliding plate.

[0013] Furthermore, the fixing rod and the fixing hole are fitted with a clearance, and the moving plate and the fixing ring are attached.

[0014] Furthermore, the sliding plate and the sliding groove are slidably connected, and the rubber pad is fitted with the sliding groove.

[0015] Furthermore, the telescopic rod consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the interior of the sleeve. A limiting block located inside the sleeve is fixedly connected to the outside of the moving rod. A through hole adapted to the moving rod is opened on one side of the sleeve.

[0016] Compared with the prior art, this utility model provides a leak-proof quick-connect coupling for pipe connections, which has the following advantages:

[0017] 1. This leak-proof quick-connect coupling for pipe connection conveniently restricts the pipe through the cooperation between the positioning groove and the retaining ring, and seals the connection between the pipe and the mounting ring through the action of the first rubber ring and the second rubber ring, improving the sealing performance. At the same time, the gap cooperation between the fixing rod and the fixing hole facilitates the fixing of the pipe, making it convenient for operators to operate.

[0018] 2. This leak-proof quick-connect fitting for pipe connections uses a spring to support the fixed rod, improving its stability.
