Technical Field

[0001] This utility model relates to the field of quick coupling technology, and more specifically, to a quick coupling and a diaphragm valve containing the coupling. Background Technology

[0002] Currently, most quick couplings on the market use threaded connections, snap-fit ​​or plug-in structures to enable quick assembly and disassembly between pipes and valve bodies.

[0003] However, under conditions of fluctuating fluid pressure or mechanical vibration, traditional snap-fit ​​or locking rings are prone to loosening, leading to leaks or even detachment at the connection, affecting the safe operation of the system. Some connectors require multiple rotations or alignments during insertion or disassembly, making the operation cumbersome and unsuitable for frequent disassembly and assembly conditions.

[0004] Therefore, there is an urgent need for a quick-connect coupling that is easy to operate and reliable to meet the dual requirements of modern industry for efficient and reliable pipeline connections. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick connector that can be quickly disassembled and installed and has a stable connection, as well as a diaphragm valve containing the connector.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quick connector includes a valve body and a pipe detachably connected to the valve body; a female connector fixedly mounted to the surface of the valve body; a male connector fixedly mounted to the surface of the pipe and plugging into the female connector; a plugging assembly fixedly mounted on the surface of the male connector; a clamping assembly fixedly mounted on the inner circumferential side of the female connector and drivingly connected to the plugging assembly; and a reset assembly installed inside the male connector and drivingly connected to the plugging assembly.

[0007] The present invention is further configured such that: the plug-in assembly includes a plurality of tapered plugs uniformly and fixedly installed on the surface of the male connector; spring clips are symmetrically installed on the outer periphery of the tapered plugs.

[0008] The present invention is further configured such that: the surface of the female connector is uniformly provided with a plurality of through holes adapted to the tapered plug; and the inner circumferential side of the through holes is provided with a groove adapted to the spring buckle.

[0010] The present invention is further configured such that: the clamping assembly includes a ball-head push rod slidably disposed with the clearance hole; an arc-shaped plate is fixed to the end of each ball-head push rod; the ball-head push rod and the tapered insert rod are movably abutted together; a return spring is sleeved on the outer peripheral side of the ball-head push rod; one end of the return spring is fixedly connected to the annular stop block.

[0011] The present invention is further configured such that: a pull rope is installed inside the tapered insert and is fixedly connected to a spring buckle; each pull rope passes through the tapered insert and is fixedly connected to a pull ring.

[0012] The present invention is further configured such that: a plurality of guide rods are uniformly fixed on the surface of the female connector; a guide hole adapted to the guide rod is opened on the surface of the male connector; a reset groove is opened between the inner walls of the guide hole; and a connecting spring is fixed on the side of the reset groove.

[0013] The present invention is further configured such that: the reset assembly includes a U-shaped rod; the U-shaped rod is slidably disposed in the reset groove; and the U-shaped rod is in movable contact with the connecting spring.

[0029] Example 1 Please see Figure 1 , Figure 4 The present invention provides the following technical solution: Specifically, it refers to a quick connector, including a valve body 1 and a pipe 2 detachably connected to the valve body 1; characterized in that: a female connector 3 is fixedly installed on the surface of the valve body 1; a male connector 4 is fixedly installed on the surface of the pipe 2 and is inserted into the female connector 3; a plug-in assembly 5 is fixedly installed on the surface of the male connector 4; a clamping assembly 6 is fixedly installed on the inner circumferential side of the female connector 3 and is kinetically connected to the plug-in assembly 5; and a reset assembly 7 is installed inside the male connector 4 and is kinetically connected to the plug-in assembly 5.

[0030] The specific application of this embodiment is as follows: When connecting valve body 1 and pipe 2, the male connector 4 is inserted into the female connector 3. During the insertion process, the linkage between the insertion component 5 and the clamping component 6 enables the male connector 4 and female connector 3 to be snapped together, while simultaneously clamping pipe 2, thus improving the stability of the connector connection. This embodiment, by setting the insertion component 5 and the clamping component 6, enables rapid connection and separation of the connector through simple insertion and removal actions, while simultaneously clamping pipe 2, effectively improving the efficiency and stability of connector assembly and disassembly.

[0031] Example 2 Please see Figure 4-6 This embodiment two is an improvement on the first embodiment as follows: Specifically, the plug-in assembly 5 includes a plurality of tapered plug rods 51 that are uniformly fixedly installed on the surface of the male connector 4; spring clips 52 are symmetrically installed on the outer periphery of the tapered plug rods 51.

[0032] The surface of the female connector 3 is evenly provided with a plurality of through holes 53 that are adapted to the tapered plug 51; the inner circumferential side of the through holes 53 is provided with a slot adapted to the spring buckle 52.

[0033] The inner circumferential side of the female connector 3 is provided with a clearance groove 8; the circumferential side of the clearance groove 8 is provided with a plurality of clearance holes 9 that are connected to the tapered insert 51; an annular stop block is fixed near the through hole 53 in the clearance groove 8; a clamping component 6 is slidably disposed in the clearance hole 9.

[0034] The clamping assembly 6 includes a ball-head push rod 61 that is slidably disposed with the clearance hole 9; an arc-shaped plate 62 is fixed to the end of each ball-head push rod 61; the ball-head push rod 61 is in movable contact with the tapered insert rod 51; a return spring 63 is sleeved on the outer peripheral side of the ball-head push rod 61; one end of the return spring 63 is fixedly connected to the annular stop block.

[0035] One specific application of this embodiment is as follows: When connecting pipes, the tapered insert 51 is aligned with the through hole 53 on the female connector 3 and inserted. During insertion, the inclined surface of the tapered insert 51 movably abuts against the ball-head push rod 61, pushing the ball-head push rod 61 to slide inward along the clearance hole 9, thereby driving the arc-shaped plate 62 to move towards the center, so that it movably abuts against the pipe surface or sleeve inside the male connector 4, forming a radial clamping force. At the same time, the spring clip 52 automatically pops out and locks into the slot in the inner wall of the through hole 53 after losing external restraint, realizing mechanical locking. This embodiment, through the transmission connection between the insertion assembly 5 and the clamping assembly 6, enables simultaneous locking and clamping during connector installation, improving the stability and reliability of the connector connection.

[0036] Example 3 Please see Figure 1-4 This embodiment three is an improvement on the first embodiment as follows: Specifically, a pull rope 10 is installed inside the tapered insert 51 and is fixedly connected to the spring buckle 52; each pull rope 10 passes through the tapered insert 51 and is fixedly connected to a pull ring 11.

[0037] The female connector 3 has several guide rods 12 evenly fixed on its surface; the male connector 4 has guide holes 13 that are adapted to the guide rods 12 on its surface; a reset groove 14 is formed between the inner walls of the guide holes 13; and a connecting spring 15 is fixed on the side of the reset groove 14.

[0038] The reset assembly 7 includes a U-shaped rod 71; the U-shaped rod 71 is slidably disposed in the reset groove 14; the U-shaped rod 71 is in movable contact with the connecting spring 15.

[0039] One end of the U-shaped rod 71 is movably abutted against the guide rod 12; the other end of the U-shaped rod 71 is fixed with a trapezoidal plate 72; the trapezoidal plate 72 is movably abutted against the pull ring 11.

[0040] A specific application of this embodiment is as follows: When disassembling or preparing to connect, first pull the pull ring 11 outward. The pull ring 11 pulls the spring clip 52 through the pull rope 10, causing it to retract into the conical insert 51. Continue pulling the pull ring 11 so that it passes over the trapezoidal plate 72 and locks above it. At this time, the spring clip 52 remains in the retracted state, facilitating insertion. Align the conical insert 51 with the through hole 53 and insert it. At the same time, the guide rod 12 on the female connector 3 enters the guide hole 13 of the male connector 4. As the insertion depth increases, the end of the guide rod 12 contacts the U-shaped rod 71 and pushes it to compress the connecting spring 15 backward. The U-shaped rod 71 drives the trapezoidal plate 72 to move synchronously, thereby releasing the trapezoidal plate 72 from limiting the pull ring 11. After the pull ring 11 is unrestricted, the spring clip 52 quickly pops out under its own elastic force and locks into the slot of the female connector 3, achieving the final locking of the connector. In this embodiment, through the transmission connection between the plug-in component 5 and the reset component 7, the pull ring 11 is pulled to retract the spring buckle 52 into the tapered plug rod 51. Then, the pull ring 11 is pulled to lock onto the trapezoidal plate 72. When the female connector 3 is inserted, the reset component 7 resets the pull ring 11, thereby causing the spring buckle 52 to pop out and lock, thus improving the overall automation level of the device.
