Description

Technology Field

[0001] This specification relates to a one-touch type coupler (coupler socket) and a coupler plug for fluid interruption. More specifically, it relates to a coupling and separation device for a one-touch type coupler and plug for fluid interruption, which enables the fluid flow to be interrupted by connecting or disconnecting the plug (or coupler) in a one-touch manner to a coupler (or plug) connected to a pipe or storage tank for transporting or storing a fluid such as a liquid or gas. Background Technology

[0002] Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section.

[0004] Generally, quick couplers are widely used to connect pipes or hoses through which fluids such as water or oil, or gases such as gas or steam, flow in a one-touch manner.

[0005] That is, a quick coupler is configured to connect a pair of pipes or hoses to allow fluid or gas to flow, while interrupting the flow path of the pipes or hoses when the pipes or hoses are separated to prevent the fluid or gas inside the pipes or hoses from leaking out.

[0006] Although not shown in the drawing, in the case of a conventional quick coupler where a plug is to be connected to the coupler, the operator holds the plug with one hand and the coupler with the other hand, and simultaneously uses two fingers to grip the sleeve of the coupler and apply force to retract it (switch to open mode). At the same time, when the plug held in the other hand is connected to the coupler and the external force applied to the sleeve is removed, the plug is connected to the coupler in a one-touch manner by the restoring force of the spring.

[0007] With this type of quick coupler, the sleeve of the coupler must always be retracted and the plug joined and secured. Therefore, when connecting the coupler and the plug to create communication, the joining operation must be performed at the position above the worker's shoulder and head, which is very cumbersome and inconvenient, resulting in poor work efficiency.

[0008] In addition, there was a problem that increased worker fatigue when the connection location of the coupler and plug was near the ceiling of the building, when there were obstacles such as walls or fire pipes around the coupler and plug, or when multiple couplers and plugs had to be connected.

[0010] A low-spill coupler equipped with a locking latch is registered in Korean Patent Publication No. 10-2681793 (July 3, 2024). The problem to be solved

[0011] The embodiments of this specification relate to a one-touch type coupler and plug coupling and separation device for fluid control, wherein a coupler (or plug) is connected to a plug (or coupler) connected to a storage tank to discharge a predetermined amount of fluid stored in a storage tank, etc., and when the coupler is separated from the plug after fluid discharge, the coupler and plug can be easily attached and detached in a one-touch manner even if there are obstructing factors such as building walls or fire pipes around the storage tank.

[0012] The embodiments of this specification relate to a coupling and separation device for one-touch type couplers and plugs for fluid control, wherein a coupler or plug connected to a plurality of pipes installed on the ceiling of a building or a storage tank on the ground, and a plug or coupler connected thereto are detachably mounted on a single jig, allowing them to be easily coupled in a one-touch manner and separated after the operation of transferring fluid. means of solving the problem

[0015] A U-shaped second plate that is detachably fixed to the first plate at an angle to the outside and supports the coupler inlet side;

[0016] Guide posts fixed at equal intervals in a vertical direction to the first plate;

[0017] A U-shaped guide bracket installed to be axially movable on the above guide post, on which a connecting member of a plug coupled to the above coupler is seated;

[0018] A U-shaped first guide pusher installed to be axially movable on a plurality of intermediate guide posts among the above guide posts, and which presses the outer end of the sleeve of the coupler to switch the sleeve to an open mode;

[0019] A pair of guide bars, one end of which is connected to the first plate and the other end of which is connected to the guide bracket, with an elongated hole formed in the longitudinal direction;

[0020] A hinge link having one end rotatably connected to the guide bar and the other end connected to the first guide pusher so as to move axially along the elongated hole;

[0021] A cushion link formed spaced apart from the outside of the hinge link, with one end rotatably connected to the guide bar and the other end fixed to the guide bracket so as to move axially along the elongated hole;

[0022] An opening / closing lever having one end rotatably connected to a fixing pin of the guide bar and the middle end rotatably connected to one end of the hinge link, which switches the sleeve to an opening mode when rotated to a first position and combines the coupler and the plug when returned to an initial position;

[0023] A joint lever having one end rotatably connected to the fixed pin and the middle end rotatably connected to one end of the cushion link, inserting the plug into the coupler when rotated to a first position and releasing the pressure of the guide bracket that presses the plug when returned to an initial position; wherein

[0024] With the plug coupled to the coupler, fluid stored in a pipe or storage tank is transferred to a predetermined location through the coupled coupler and plug, and when the opening / closing lever is rotated back to the first position, the sleeve is switched to an opening mode to separate the plug from the coupler, and when the opening / closing lever is returned to the initial position, the first guide pusher is disengaged from the sleeve to switch the sleeve to a closing mode.

[0044] Guide posts (16, 18, 20, 22), guide bar (34), hinge link (36), cushion link (38), opening / closing lever (40) and joint lever (42) are characterized by being arranged symmetrically.

[0045] That is, regarding the guide posts (16, 18, 20, 22), guide bar (34), hinge link (36), cushion link (38), opening / closing lever (40), and joint lever (42) located on the left side of the drawing, the guide posts (16a, 18a, 20a, 22a), guide bar (34a), hinge link (36a), cushion link (38a), opening / closing lever (40a), and joint lever (42a) located on the right side of the drawing have the same structure and are formed in a left-right symmetrical shape, so the drawing symbols are indicated by adding "a".

[0046] At this time, since the aforementioned coupler (10) and plug (54) are commonly used in the technical field to which this specification belongs to for connecting pipes and hoses, etc. in a one-touch manner, a detailed description of their configuration and function is omitted.

[0048] According to a more preferred embodiment, as shown in FIG. 1, when a plug (54) and a coupler (10) are connected based on a coupler (10) that is detachably fixed to the outer surface of the aforementioned second plate (14) and connected to the fixed member (58), the device is characterized by having a first fastener (44) for detachably fixing a coupling and separation device (100) (referring to a jig) to the fixed member (58).

[0049] As illustrated in FIG. 1, when the coupler (10) and the plug (54) are connected based on the plug (54) which is detachably fixed to the outer surface of the aforementioned guide bracket (26) and connected to the fixed member (58), the coupling and separation device (100) is characterized by having a second fastening member (46) for detachably fixing the fixed member (58).

[0050] As shown in FIG. 1, it is characterized by having a first stay lever (48) for a handle to grip by connecting the other ends of the left and right opening / closing levers (40, 40a) formed symmetrically on the left and right sides.

[0051] As shown in FIG. 1, it is characterized by having a second stay lever (50) for a handle to grip by connecting the ends of the left and right joint levers (42, 42a) formed symmetrically on the left and right sides.

[0052] As shown in FIG. 1, the aforementioned second plate (14) is characterized by being detachably screw-coupled and fixed to one end of the uppermost guide post (16) among the guide posts (16, 18, 20, 22).

[0053] As illustrated in FIG. 1, the device is characterized by having a first elastic member (62) installed on a plurality of guide posts (18, 20) on the intermediate side between the first guide pusher (30) and the second guide pusher (32) described above, which is compressed when the opening / closing lever (40) is rotated to a first position and, when it returns to an initial position, the first guide pusher (30) presses the outer end of the sleeve (28) by means of elastic force, thereby connecting the coupler (10) and the plug (54) (as an example, a conventional compression coil spring may be used, but is not limited thereto).

[0054] As illustrated in FIG. 1, the device is characterized by having a second elastic member (64) installed on a plurality of guide posts (18, 20) on the intermediate side between the first plate (12) and the second guide pusher (32) described above, and for adding the elastic force of the first elastic member (62) so that the first guide pusher (30) is compressed when the opening / closing lever (40) is rotated to the first position and is smoothly detached from the outer end of the sleeve (28) by the elastic force when it returns to the initial position (for example, a conventional compression coil spring may be used, but this does not mean that it is limited thereto).

[0055] As illustrated in FIG. 1, the device is characterized by having a third elastic member (66) (as an example, a conventional compression coil spring may be used, but is not limited thereto) and a fourth elastic member (68) (as an example, a conventional compression coil spring may be used, but is not limited thereto), which are installed on the uppermost and lowermost guide posts (16, 22) between the first plate (12) and the guide bracket (26) described above, and which are compressed when the joint lever (42) is rotated to a first position and, when it returns to an initial position, cause the guide bracket (26) that presses against the outer end of the plug (54) by means of elastic force to detach.

[0057] Hereinafter, a coupling and separation device for a one-touch type coupler and a plug for fluid control according to one embodiment of the present specification will be described with reference to the attached drawings.

[0059] As shown in FIGS. 1 to 8, a coupler (10) that is pre-connected to a pipe that transports various fluids installed in the ceiling of a building and a storage tank on the ground (referred to as "fixed member" 58) where fluids are stored can be connected in a one-touch manner by using a coupling and separation device (100) (referred to as a jig) to connect a plug (54) to which a hose (56) is connected.

[0060] To explain this in detail, a coupler (10) connected to the aforementioned fixed member (58) is placed on one side of the coupling and separation device (100), and a plug (54) connected to a hose (56) is placed on the other side of the coupling and separation device (100) opposite to the coupler (10).

[0061] The coupling and separation device (100) can be fixed to the fixed member (58) by means of a first fastening member (44) which is detachably fixed to the outer surface of the second plate (14) described above by means of a fastening member (see S10 in FIG. 7). At this time, the coupler (10) can be compressed and supported by the U-shaped clamp (44a) of the first fastening member (44).

[0062] As shown in FIG. 4b, when the first stay lever (48) for the aforementioned handle is grasped and the fixing pin (60), which rotatably fixes the opening / closing lever (40) and the joint lever (42) to the guide bar (34), is rotated clockwise (forward direction) around the central axis, the sleeve (28) of the conventional coupler (10) can be switched to an open mode (at this time, the elastic member (not indicated in the drawing) that holds the sleeve (28) is subjected to a compressive force) (see S20 in FIG. 7).

[0063] That is, the outer end of the sleeve (28) is pressed by the first guide pusher (30), which is connected to the other end of the aforementioned hinge link (36) and is coupled to be movable axially along the middle guide force (18, 20) among the guide posts (16, 18, 20, 22), thereby moving it to the left direction in the drawing, so that the sleeve (28) can be switched to an open mode.

[0064] As illustrated in FIG. 4c, when the second stay lever (50) for the handle described above is grasped and the fixing pin (60) is rotated clockwise (forward) around the central axis, the plug (54) can be inserted into the coupler (10) (at this time, the sleeve (28) of the coupler (10) remains in an open mode state) (see S30 in FIG. 7).

[0065] That is, the outer end of the plug (54) is pressed by the guide bracket (26), which is connected to the other end of the aforementioned cushion link (38) and coupled so as to be movable axially along the guide posts (16, 18, 20, 22), thereby moving it to the left direction in the drawing, so that the plug (54) can be inserted into the coupler (10). At this time, the sleeve (28) of the coupler (10) maintains the open mode as the opening / closing lever (40) is rotated.

[0066] As shown in FIG. 4d, when the opening / closing lever (40) is rotated in the reverse direction (counterclockwise) around the fixing pin (60) as the central axis by gripping the aforementioned first stay lever (48) to return it to the initial position, the coupler (10) and the plug (54) can be combined (see S40 in FIG. 8).

[0067] That is, when the external force applied to the outer end of the sleeve (28) by the first guide pusher (30) is removed by returning the aforementioned opening / closing lever (40) to its initial position, the first guide pusher (30) is moved to the right direction in the drawing by the restoring force of the second elastic member (64) installed in the guide post (18, 20) between the first plate (12) and the second guide pusher (32) and the first elastic member (62) installed in the guide post (18, 20) between the first guide pusher (30) and the second guide pusher (32), thereby returning the sleeve (28) to its initial position by the restoring force of the elastic member installed in the coupler (10), so that the coupler (10) and the plug (54) can be connected.

[0068] As shown in FIG. 4e, when the joint lever (42) is rotated in the reverse direction (counterclockwise) around the fixing pin (60) as the central axis by gripping the aforementioned second stay lever (50) to return it to the initial position, the guide bracket (26) can be detached from the outer end of the plug (54) (see S50 in FIG. 7).

[0069] That is, when the external force applied to the outer end of the plug (54) by the guide bracket (26) is removed by returning the joint lever (42) to its initial position, the guide bracket (26) can be returned to its initial position by the restoring force of the third elastic member (66) installed on the uppermost guide post (16) between the first plate (12) and the guide bracket (26), and the fourth elastic member (68) installed on the lowermost guide post (22) between the first plate (12) and the guide bracket (26), by moving along the guide posts (16, 18, 20, 22) in the right direction in the drawing.

[0070] The work of transferring fluid from a fixed member (referring to a pipe installed on the ceiling of a building for transferring ordinary fluids, etc.) to a predetermined location is performed by means of a coupler (10) and a plug (54) connected by a coupling and separation device (100) (referring to a jig) that is fixed to the fixed member (58) by the aforementioned first coupling member (44) (see S100 in FIG. 8).

[0071] As illustrated in FIG. 4f, when the operation of transferring fluid within the fixed member (58) by the coupler (10) and plug (54) which are maintained in a fixed state on the aforementioned jig is completed, the first stay lever (48) is grasped and the opening / closing lever (40) is rotated in the forward direction (clockwise) with the fixing pin (60) as the central axis, thereby pressing the sleeve (28) of the coupler (10) by the first guide pusher (30) and moving it to the left direction in the drawing (at this time, the elastic member inside the coupler (10) receives a compressive force). That is, the sleeve (28) can be switched to an open mode (see S200 in FIG. 8).

[0072] As shown by the dashed line in FIG. 4f, when the opening / closing lever (40) is rotated in the forward direction (clockwise) around the fixing pin (60) as the central axis by gripping the aforementioned first stay lever (48) to return it to the initial position, the first guide pusher (30) is returned to the initial position to remove the external force pressing the outer end of the sleeve (28), thereby returning the sleeve (28) to the initial position and allowing the coupler (10) to maintain a sealed state by moving the internal plunger (10a) to the initial position (see FIG. 5).

[0073] At this time, when the plug (54) is separated from the aforementioned coupler (10), the technical details regarding the coupler (10) and the plug (54) being switched to a sealed state by the internal plunger (10a, 54a) are applied substantially identically to those commonly used in the technical field to which this specification belongs, so a detailed description of their configuration and function is omitted.

[0074] Accordingly, the plug (54) can be separated from the coupler (100) which is seated on and fixed to the coupling and separation device (100) (referring to a jig) that maintains the state of being fixed to the fixed member (58) by the first fastening member (44) fixed to the second plate (14) described above (see S300 in FIG. 8).

[0075] As described above, according to the coupling and separation device of a one-touch type coupler and plug for fluid interruption according to the embodiment of the present specification,

[0076] In order to discharge (or transfer) a predetermined amount of fluid stored in a pipe installed on the ceiling of a building or a storage tank (referred to as the fixed member (58)) on the floor by means of a pump, etc., a jig (referred to as the coupling and separation device (100)) is fixed to a coupler (or plug) connected to the fixed member using the first and second fastening members (44, 46), and then a plug (or coupler) corresponding to the coupler (or plug) is connected in a one-touch manner using the jig (100) to discharge (transfer) the fluid, and then the plug (54) is separated from the coupler (10) fixed to the jig (100) which maintains a fixed state on the fixed member (58), even if there are obstacles such as building walls or fire pipes around the pipe or storage tank, the plug (54) can be easily separated from the coupler (10) in a one-touch manner using the jig (100), thereby improving workability and reducing worker fatigue.

[0078] Although the present specification has described preferred technical concepts by reference to examples, those skilled in the art to which the specification belongs will be able to make various modifications and equivalent alternative embodiments within the scope of the essential characteristics of the specification.

[0079] In other words, the disclosed content is merely an example and can be modified and implemented in various ways by a person skilled in the art without departing from the gist of the claim claimed in the scope of the claim; therefore, the scope of protection of the disclosed content is not limited to the specific embodiments described above.
