More specifically, FIGS. 1A and 2A show the separation state of the male coupler and the female coupler, and FIGS. 1B and 2B show the coupled state of the male coupler and the female coupler.

1A to 2B, the coupling device 1000 according to an embodiment of the present invention may include a male coupler 100 and a female coupler 200. At this time, the first coupler and the second flow passage extending from the hoses A and B are formed in the male coupler 100 and the female coupler 200. In the detached state of the male coupler 100 and the female coupler 200, respectively, the coupler 100 may be configured to be in fluid communication with each other according to the coupling of the male coupler 100 and the female coupler 200.

The male coupler 100 may be coupled to the female coupler 200 by inserting at least a portion of the female coupler 200 into the interior of the female coupler 200 (that is, the accommodating part 240). As shown in FIG. 1, the male coupler 100 preferably has one side surface of the first male coupler 100-1 and the second male coupler 100-2 having the same configuration. Can be formed.

Each of the first and second male couplers 100-1 and 2 may be configured to include a first cylinder part 130 and a protrusion 140 on one side and the other side in the longitudinal direction.

The first cylinder part 130 may include a first spring part 120 coupled to one end of the first packing part 110 and the first packing part 110 therein. In addition, at least one through part 131 may be formed at one end of the first cylinder part 130 at predetermined intervals along a circumference of the protrusion 140. When the male coupler 100 and the female coupler 200 are separated from each other, the first packing part 110 is connected to the protrusion 140 by the repulsive force of the first spring part 120 (that is, of the protrusion 140). The inner diameter may be in close contact with the stepped inner surface formed by decreasing the first cylinder portion 130), thereby closing the first flow path and simultaneously sealing each of the through portions 131.

The protruding portion 140 may extend to protrude in the longitudinal direction from one end of the first cylinder portion 130, and may be formed such that the outer diameter and the inner diameter are smaller than the outer diameter and the inner diameter of the first cylinder portion 130. Since the inside of the protrusion 140 is connected to the inside of the first cylinder 130, a first flow path is formed in each of the first and second male couplers 100-1 and 2. In addition, at the front end of the protrusion 140, at least one first protrusion 141 may be formed to be spaced apart from each other at predetermined intervals along a circumference. The tip of the protrusion 140 in which the first protrusion 141 is formed is a passage through which the fluid passes while opening the second flow path of the female coupler 200 when the female coupler 200 is coupled to the tip as described below. It serves to provide.

The female coupler 200 may accommodate at least a portion of the male coupler 100 inward. The female coupler 200, like the male coupler 100, preferably, the one side of the first female coupler 200-1 and the second female coupler 200-2 having the same configuration is mutually coupled Can be formed.

The second cylinder part 230 may be provided with a second spring part 120 coupled to one end of the second packing part 210 and the first packing part 210 therein. The second packing part 210 is the same as the first packing part 110, when the male coupler 100 and the female coupler 200 are separated, the receiving part 240 by the repulsive force of the first spring part 220. The second flow path can be sealed by being in close contact with the connection portion (ie, the inner surface of the step shape formed by decreasing the inner diameter of the second accommodating portion 241 than the second cylinder portion 230).

The accommodating part 240 is a component for inserting at least a portion of the male coupler 100 into the inside, and may include a first accommodating part 241 and a second accommodating part 242.

The first cylinder part 130 of the male coupler 100 may be inserted into the first accommodating part 241. In addition, at least one second protrusion 243 may be formed at an inner end of the first accommodating part 241 to correspond to the position of the through part 131 of the male coupler 100. When the second coupler 243 is coupled to the male coupler 100 and the female coupler 200, each of the second protrusions 243 is inserted into a corresponding through portion 131 to couple the first packing part 110 of the male coupler 100 to each other. By moving in the direction opposite to the direction, it serves to open the first flow path.

The second accommodating part 241 is a configuration in which the protrusion 140 of the male coupler 100 is inserted, the inner diameter of which is formed to correspond to the outer diameter of the protruding part 140, and the first accommodating part 521 and the first cylinder part. It may be configured smaller than 130. The second accommodating part 241 is connected to the inside of the second cylinder part 230, thereby forming a second flow path inside the female coupler 200. On the other hand, the length of the second receiving portion 241 may be formed shorter than the length of the protrusion 140 of the male coupler (100). Therefore, when the male coupler 100 and the female coupler 200 are coupled to each other, a portion of the tip (particularly, the first protrusion 141) of the protrusion 140 inserted into the second accommodating part 241 is formed in the second cylinder part ( The second flow path may be opened by protruding into the inside of the 230 and pushing the second packing part 210 in a direction opposite to the coupling direction.

According to the coupling of the male coupler 100 and the female coupler 200, the first flow path and the second flow path are opened, so that the process of fluid communication with each other is as follows.

First, in a state in which the male coupler 100 and the female coupler 200 are separated, the first flow path and the second flow path are closed by the first packing part 110 and the second packing part 210, respectively.

Then, as the coupler 100 and the female coupler 200 is coupled, the protrusion 140 of the male coupler 100 is inserted into the second receiving portion 242 of the female coupler 200 to A part of the tip protrudes into the second cylinder part 230 of the female coupler 200, and the tip of the protruding part 140 protrudes in such a manner as to push the second packing part 210 in a direction opposite to the coupling direction. The second flow path is opened. At this time, the spaced gap between the first protrusion 141 at the tip of the protrusion 140 forms a passage through which the fluid passes.

In addition, according to the coupling, when the first cylinder portion 130 of the male coupler 100 is inserted into the first receiving portion 241 of the female coupler 200, the second projection formed in the first receiving portion 241 243 may be inserted into the penetrating portion 131 of the corresponding male coupler 100 so that a portion of the tip of the second protrusion 243 may protrude into the first cylinder portion 130. The front end of the protruding second protrusion 243 opens the first flow path by pushing the first packing part 110 in a direction opposite to the coupling direction.

In this manner, both the first flow path and the second flow path are opened to communicate with each other, and thus, the hoses A and B connected to the male coupler 100 and the female coupler 200 exchange fluids with each other. Can be connected.

3 shows a packing part of a coupling device according to an embodiment of the invention.

Referring to FIG. 3, at least one wing portion 111 and 211 may be spaced apart at predetermined intervals from the first packing part 110 and the second packing part 210 of the coupling device 1000 along an outer circumferential surface thereof. Can be.

When opening the first flow path and the second flow path by the coupling of the male coupler 100 and the female coupler 200, the gaps between the wing portions 111 and 211 form a passage through which the fluid passes. The fluid can be moved more smoothly.

In addition, the wing 111 of the first packing part 110 may serve to seal the through part 131 of the male coupler 100. That is, the through part 131 of the male coupler 100 is implemented to be formed at a position corresponding to at least one of the wing parts 111 of the first packing part 110, and thus, the first packing part 110. The central part of the male coupler may seal the first flow path of the male coupler 100, and the wing 111 may be configured to serve to seal the through part 131, respectively.

The first packing part 110 and the second packing part 120 may be formed of various materials capable of providing a hermetic sealing performance such as, for example, rubber or silicone.

4 shows a coupling device according to an embodiment of the invention, and FIGS. 5A and 5B show longitudinal cross-sectional views of the coupling device according to an embodiment of the invention.

4 to 5B, the coupling device 2000 may further include a fixing groove 350 and a locking pin 460, respectively. Here, the rest of the configuration except the fixing groove 350 and the locking pin 460 of the coupling device 2000 is the same as the coupling device 1000 described above with reference to FIGS. Is omitted.

One region of the female coupler 400 may be provided with a locking pin 460 for fixing the coupling state with the male coupler 300. The locking pin 460 may be formed on the coupling site of the first and second female couplers. Meanwhile, at least one fixing groove 350 may be formed in at least one region of the side of the male coupler 300. The fixing grooves 350 may be formed, one on each of the outer side surfaces of the first cylinder portion of the first male coupler and the first cylinder portion of the second male coupler.

After the male coupler 300 is inserted into the female coupler 400, a user may fix the coupling of the male coupler 300 and the female coupler 400 by performing a predetermined operation on the locking pin 460. . That is, for example, when the user rotates the locking pin 460 in one direction, at least a portion of the locking pin 460 is accommodated in the fixing groove 350 of the male coupler 300, whereby the male coupler 300 and the female are rotated. It may be implemented to secure the coupling of the coupler 400.

To this end, the locking pin 460 has a cross-section and at least a longitudinal length different from each other, for example, to form a rectangular shape, both ends of the longitudinal length of the region is the curvature of the inner surface of the fixing groove 350 It may be configured to form a curved surface corresponding to, and may be configured to be rotatable in a state in which at least a portion of the locking pin 460 is inserted into the locking pin receiving space 450 of the female coupler 400. In addition, a through hole (not shown) communicating with the lock pin accommodation space 450 may be formed on an inner surface of the accommodation portion of the female coupler 400. Therefore, when the locking pin 460 is rotated in one direction, a portion of the locking pin 460 is protruded into the fixing groove 350 through the through-hole of the inner side of the receiving portion to accommodate the male coupler 300 and the female. The coupling of the coupler 400 can be firmly fixed.

On the other hand, in this case, the user rotates the locking pin 460 in the opposite direction, the part of the received locking pin 460 can be separated from the fixing groove 350, and then, the coupler 300 and the female coupler ( Of course, it is possible to perform the separation for 400).

However, the form and coupling manner of the locking pin 460 as an example, it may be used in various ways in a range known to those skilled in the art. For example, a part of the locking pin 460 may be implemented to be coupled to or separated from the fixing groove 350 through a vertical movement method rather than the rotation method. That is, one end of the locking pin 460 is configured to protrude on the upper surface of the female coupler 400 in the form of a button (button), the user presses one end of the locking pin 460 after the coupling of the coupler 300 As the locking pin 460 is moved downward, a part of the locking pin 460 may be accommodated in the fixing groove 350. In addition, in this case, when the user presses one end of the locking pin 460 again, the locking pin 460 may be moved upward by elasticity such as a spring, so that the locking pin 460 may be separated from the fixing groove 350.
