Description

Technical Field

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

[0002] Various quick connector assemblies are often needed in chemical production. The quick connector assembly consists of a male connector and a female connector. When the two are connected, a channel for gas or liquid circulation is formed to realize the transmission operation of liquid or liquid.

[0003] In the prior art, the female joint achieves sealing through the sliding friction between the cam handle and the male joint (i.e., the cam is pressed) and the piston-type sealing ring in the female joint. When the cam handle of the female joint is docked with the male joint, the operator needs to manually move the cam handle to make it contact and rub with the arc-shaped groove of the male joint to clamp it. The cam and the male joint wear each other during use, and the sealing failure problem is likely to occur after long-term use, and the service life of the quick connector assembly is difficult to guarantee. Furthermore, the piston-type sealing ring has an opening and closing delay, and cannot be sealed synchronously with the male joint during the docking and separation process, and there is leakage during the opening and closing process. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a joint assembly to enhance the sealing effect of the male joint and the female joint, improve the service life of the joint assembly and avoid docking delays and leakage.

[0005] Based on this, the utility model provides a connector assembly, including a male connector and a female connector, wherein the male connector includes:

[0006] Valve body;

[0007] A valve core is arranged in the valve body;

[0008] A main shaft is disposed in the valve body and connected to the valve core, and the other end of the main shaft extends out of the valve body;

[0009] A handle, disposed outside the valve body and connected to the main shaft to drive the valve core to move inside the valve body;

[0010] A moving ring is arranged in the valve body and sleeved on the valve core. The moving ring is located at the end of the valve body close to the female joint. The top surface of the moving ring is connected to the valve body through a sealing spring. The moving ring is provided with a first sealing ring against the side wall of the valve body, the moving ring is provided with a second sealing ring against the side wall of the valve core, and the bottom surface of the moving ring facing the female joint is provided with a third sealing ring;

[0011] When the male connector is docked with the female connector, the claws of the female connector are inserted into the docking groove to hold the valve body tightly, and the sealing spring pushes the dynamic ring to abut against the female connector.

[0012] In some embodiments of the present application, a connecting block, a hook plate and a transmission pin are provided in the valve body, the main shaft is connected to the connecting block, the connecting block is connected to the hook plate, the transmission pin is provided on the valve core and connected to the hook plate, and the hook plate is arranged in an arc shape.

[0013] In some embodiments of the present application, further comprising:

[0014] A first regulating block is disposed outside the valve body and connected thereto, and a first regulating hole is formed on the first regulating block;

[0015] The limiting hook comprises a first adjusting rod, a second adjusting rod and a connecting rod connecting the first adjusting rod and the second adjusting rod, wherein the first adjusting rod is inserted into the first adjusting hole and can slide along the first adjusting hole;

[0016] A limit block is provided at the edge of the handle, and the limit hook has a locked state and an unlocked state. When the limit hook is in the locked state, the first adjustment rod in the first adjustment hole abuts against the limit block to cooperate with the limit block to prevent the handle from rotating. When the limit hook is in the unlocked state, the second adjustment rod abuts against the female joint, and the first adjustment rod is away from the limit block and no longer prevents the handle from rotating.

[0017] In some embodiments of the present application, the valve body is provided with a second adjusting block connected thereto, the second adjusting block is provided with a second adjusting hole, and the second adjusting rod is passed through the second adjusting hole.

[0018] In some embodiments of the present application, an adjusting spring is sleeved on the second adjusting rod, and a limiting plate connected to the end of the second adjusting rod is provided, and two ends of the adjusting spring respectively abut against the second adjusting block and the limiting plate.

[0019] In some embodiments of the present application, a limiting hole is provided on the second adjusting rod, a limiting column is passed through the limiting hole, and the limiting sheet is passed through the second adjusting rod and abuts against the limiting column.

[0020] In some embodiments of the present application, the limiting holes are provided in a plurality and are sequentially arranged along the second adjusting rod, and the limiting column is inserted into any one of the limiting holes.

[0021] Compared with the prior art, the connector assembly provided by the present invention has the following advantages:

[0022] When the female joint and the male joint are docked, the docking claws on the female joint quickly clamp the docking groove of the male joint, ensuring the flatness of the sealing surface of the female joint and compacting the end face seal of the male joint. At this time, the sealing spring and the moving ring are subjected to pressure given by the female joint. The sealing spring gives the moving ring a pressure toward the female joint due to the pressure, and then the moving ring has a tendency to move toward the female joint, ensuring the continuous effectiveness of the seal at the moment of opening the valve; further, the effective force stroke range of the spring body is greater than the vertical distance of wear of the docking groove of the male joint. The setting of the moving ring and the sealing spring effectively increases the service life of the male joint. The sealing spring can reasonably control the effective range of the male joint seal, that is, the sealing spring can provide a fixed elastic force within the effective installation space to ensure that the sealing surface will not fail, thus achieving a complete sealing effect.

DETAILED DESCRIPTION

[0029] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] It should be understood that the terms "front", "rear", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "front" information may also be referred to as "rear" information, and "rear" information may also be referred to as "front" information without departing from the scope of the present invention.

[0031] like Figures 1 to 5 As shown, the utility model provides a joint assembly, including a male joint and a female joint. Specifically, the male joint of the present application includes a valve body 1, a valve core 2, a main shaft 3, a handle 4 and a moving ring 11 and other structures, wherein the valve core 2 is arranged in the valve body 1; the main shaft 3 is arranged in the valve body 1 and connected to the valve core 2, and the other end of the main shaft 3 extends to the outside of the valve body 1; the handle 4 is arranged outside the valve body 1 and connected to the main shaft 3 to drive the valve core 2 to move in the valve body 1; the moving ring 11 is arranged in the valve body 1 and sleeved on the valve core 2, the moving ring 11 is located at the end of the valve body 1 close to the female joint, and the moving ring 11 is located at the end of the valve body 1 close to the female joint. The top surface of the ring 11 is connected to the valve body 1 through a sealing spring 12, a first sealing ring 13 is provided on the side wall of the valve body 1 where the moving ring 11 abuts, a second sealing ring 14 is provided on the side wall of the valve core 2 where the moving ring 11 abuts, and a third sealing ring 15 is provided on the bottom surface of the moving ring 11 facing the female connector; at the same time, for the female connector of the present application, a plurality of docking claws are provided at its end, and when the male connector and the female connector are docked, the male connector touches the bottom foot of the female connector, and at this time, the docking claws are automatically triggered and quickly clamp the docking groove 101 of the male connector, thereby realizing a fixed connection between the male connector and the female connector.

[0032] Based on the above structure, when the female connector and the male connector are docked, the docking claws on the female connector quickly clamp the docking groove 101 of the male connector, ensuring the flatness of the sealing surface of the female connector and compacting the end face seal of the male connector. At this time, the sealing spring 12 and the moving ring 11 are subjected to the pressure given by the female connector. The sealing spring 12 gives the moving ring 11 a pressure toward the female connector due to the pressure, and then the moving ring 11 has a tendency to move toward the female connector, ensuring the continuous effectiveness of the seal at the moment of opening the valve; further, the effective force stroke range of the spring body is greater than the vertical distance of wear of the docking groove 101 of the male connector. The setting of the moving ring 11 and the sealing spring 12 effectively increases the service life of the male connector, and the sealing spring 12 can reasonably control the effective range of the male connector seal, that is, the sealing spring 12 can provide a fixed elastic force within the effective installation space to ensure that the sealing surface will not fail, thereby achieving a completely sealed effect.

[0033] Optionally, in some embodiments of the present application, the male connector of the connector assembly further includes a connection block 8, a hook plate 9 and a transmission pin 10 disposed in the valve body 1, wherein the main shaft 3 is connected to the connection block 8, the connection block 8 is connected to the hook plate 9, the transmission pin 10 is disposed on the valve core 2 and connected to the hook plate 9, and the hook plate 9 is arranged in an arc shape. When in use, the operator rotates the handle 4, at which time the main shaft 3 and the connection block 8 rotate synchronously with the rotation of the handle 4, driving the arc-shaped hook plate 9 to move up and down and then driving the transmission pin 10 and the valve core 2 to move, and the eccentric design of the handle 4 rotating main shaft 3 and the center line of the valve body 1 is adopted to ensure the stable opening and closing of the operating handle 4 without jamming; further, the present application minimizes the unnecessary space in the valve body 1 without affecting the flow rate, and the layout of the component structure system is reasonable.

[0034] Optionally, in some embodiments of the present application, a limit block 401 is provided on the edge of the handle 4, and a first adjustment block 6 and a second adjustment block 7 connected thereto are provided outside the valve body 1, a first adjustment hole 601 is provided on the first adjustment block 6, and a second adjustment hole 701 is provided on the second adjustment block 7, and the axes of the first adjustment hole 601 and the second adjustment hole 701 are parallel to the axis of the valve body 1. Further, a limit hook 5 arranged in a U shape is provided outside the valve body 1, which includes a first adjustment rod 501 and a second adjustment rod 502 parallel to each other and a connecting rod 503 connecting the two, and the first adjustment rod 501 is penetrated by a first adjustment rod 501 and a second adjustment rod 502 are parallel to each other. In the first adjusting hole 601, the second adjusting rod 502 is inserted into the second adjusting hole 701, and at the same time, the first adjusting rod 501 and the second adjusting rod 502 can both slide in the corresponding adjusting holes; since the position of the limit hook 5 is adjustable, the limit hook 5 has a locked state and an unlocked state accordingly. When the limit hook 5 is in the locked state, the first adjusting rod 501 in the first adjusting hole 601 abuts against the valve body 1 and cooperates with the limit block 401 to prevent the handle 4 from rotating. When the limit hook 5 is in the unlocked state, the second adjusting rod 502 abuts against the female joint, and the first adjusting rod 501 is away from the limit block 401, and no longer prevents the handle 4 from rotating.

[0035] Based on the above structure, the present application confirms the docking condition of the male connector and the female connector by setting a limit hook 5 to avoid material leakage. Before use, the limit hook 5 is pushed to make its first adjustment rod 501 abut against the valve body 1. At this time, the first adjustment rod 501 can abut against the limit block 401 and cooperate with the limit block 401 to prevent the handle 4 from rotating, and the second adjustment rod 502 moves downward with the position adjustment of the first adjustment rod 501; and when the female connector and the male connector are docked, the shell end face of the female connector abuts against the second adjustment rod 502 and pushes the second adjustment rod 502 to move upward continuously. At this time, the first adjustment rod 501 will also move upward with the movement of the second adjustment rod 502 until it no longer abuts against the limit block 401. At this time, the limit hook 5 releases the restriction on the handle 4, and the handle 4 can rotate smoothly and open the male connector. Obviously, in order to close the male connector again in the open state to cut off the material delivery, it is also necessary to ensure that the limit hook 5 is in the unlocked state. At this time, the effective connection between the male connector and the female connector is also ensured, which effectively improves the overall safety, greatly reduces the risk of material leakage, and improves the user experience of the operator.

[0036] Optionally, in some embodiments of the present application, the second adjusting rod 502 is sleeved with an adjusting spring 504 and a limiting plate 505, the limiting plate 505 is located at the end of the adjusting rod and connected thereto, and the two ends of the adjusting spring 504 respectively abut against the second adjusting block 7 and the limiting plate 505. Based on the above structure, the setting of the adjusting spring 504 can give the limiting hook 5 a force close to the valve body 1, so that the first adjusting rod 501 of the limiting hook 5 is always close to the valve body 1, thereby preventing the handle 4 from rotating; further, when the male connector and the female connector are docked, the second adjusting rod 502 moves upward under the action of the female connector, at which time the adjusting spring 504 is compressed and gives more pressure to the limiting hook 5, so as to ensure that the limiting hook 5 can automatically return to the initial position after the connection between the female connector and the male connector is released, thereby limiting the handle 4 again.

[0037] Further, for the second adjustment rod 502 of the present application, a limiting hole 506 is provided on the rod body thereof, a limiting column 507 is penetrated in the limiting hole 506, and the limiting piece 505 is penetrated on the second adjustment rod 502 and abuts against the limiting column 507, that is, the present application fixes the limiting piece 505 by setting the limiting column 507; further, the second adjustment rod 502 may be provided with a plurality of limiting holes 506, in which case each limiting hole 506 is sequentially arranged along the second adjustment rod 502, and the limiting column 507 is penetrated in any of the limiting holes 506. In this way, the operator can adjust the distance between the limiting piece 505 and the second adjustment block 7 by changing the position of the limiting column 507, thereby changing the compression degree of the adjustment spring 504 to obtain a better adjustment effect.

[0038] In summary, the utility model provides a joint assembly, including a male joint and a female joint, wherein the male joint includes a valve body, a valve core, a main shaft, a handle and a moving ring and other structures, wherein the valve core is arranged in the valve body; the main shaft is arranged in the valve body and connected to the valve core, and the other end of the main shaft extends to the outside of the valve body; the handle is arranged outside the valve body and connected to the main shaft to drive the valve core to move in the valve body; the moving ring is arranged in the valve body and sleeved on the valve core, the moving ring is located at the end of the valve body close to the female joint, the top surface of the moving ring is connected to the valve body through a sealing spring, the moving ring is provided with a first sealing ring against the side wall of the valve body, the moving ring is provided with a second sealing ring against the side wall of the valve core, and the bottom surface of the moving ring facing the female joint is provided with a third sealing ring.
