It is composed of

Referring to FIG. 1, the present invention is composed of three parts, a part for fixing a hose, a part for fixing a connector, and a handle. Both handles 12 are located at one side with the fixing part 14 as the center, and the inner end of each handle 12 is used to support the connector and the inner cover 26 used to fix the hose, respectively. Support base unit 32 is connected. It can be seen that the inner cover 26 and the support storage unit 32 are connected to the pair of handles 12, respectively.

The handle 12 is rotatably installed around the fixing part 14, and the inner cover 26 and the supporter storage part 32 also approach each other as the handle 12 is pulled inward. At this time, by adjusting the length of the handle 12, it is possible to adjust the pressure applied to the hose and connector installed on the inner cover 26 and the support storage unit 32.

The inner cover 26 is integrally formed with a pair of fixing protrusions 16 at a predetermined distance from the upper surface, and the catching rod 18 is inserted between the fixing protrusions 16. In addition, a semi-circular space for forming the hose housing portion 28 is formed at the shortest portion extending outward of the inner cover 26. The semicircular space is combined with the semicircular space formed in the outer cover 24 to form a space for storing the hose. In these semicircular spaces, threaded grooves are formed to prevent the hose from being pushed in when it is inserted. In addition, the guide pin 30 is inserted into the side of the inner cover 26. Guide pin 30 is to guide the movement of the connector support (34).

The outer cover 24 which is coupled to the inner cover 26 to fix the hose is coupled by the hinge connecting pin 30a at the inner cover 26 and the lower end thereof. Therefore, the outer cover 24 in the fixed state of the inner cover 26 is separated downward with respect to the lower hinge connecting pin (30a). The fixing rod 20 is installed on the upper side of the outer cover 24 to be coupled to the inner cover 26. In the middle of the fixing rod 20 is also formed with a locking groove 22 integrally by pulling the fixing rod 20 to engage the locking groove 22 to the locking rod 18 of the inner cover 24 for fastening. To complete. The fixing rod 20 is also fixed to the upper side of the outer cover 24 to be rotatable by the fixing pin 24a.

On the other hand, the support holder 32 is a state in which both the side and the front are open, the connector support 34 for fixing the connector therein is inserted. The connector support 34 has a bolt 36 for supporting the connector to the outside and the guide pin 30 penetrates the side surface. Also on the upper surface a pin 38 is also fixed to the connector support 34. The connector support 34 is movable along the guide pin 30, and the pin 38 and the connector support 34 simultaneously move along the long hole 40. Due to this structure, the connector support 34 is not separated from the support housing 32 and is operated so that the connector is correctly inserted into the inner diameter of the hose when the hose and the connector are coupled.

4 and 5 illustrate the coupled state of the outer cover 24 and the inner cover 26, respectively showing a state in which the fastening state and the separated state. As shown in FIG. 4, the fixing rod 20 moves upwardly of the inner cover 26 while the outer cover 24 and the inner cover 26 are coupled around the hinge connecting pin 30a and thus caught. The catching grooves 22 are fastened to each other by the rods 18. In addition, the hose housing 28 is formed due to the combination of the outer cover 24 and the inner cover 26. The hose to be connected to the connector through the hose housing 28 is sandwiched.

In this state, when the fixing rod 20 is pulled to the left side of the drawing, the catching groove 22 is separated from the catching rod 18 so that the inner cover 26 and the outer cover 24 are centered on the hinge connecting pin 30a. Are separated from each other. Thus, the hose housing 28 is left in the form of a semicircular space. This is shown in FIG. When the hose is positioned in this separated state and fastened as shown in FIG. 4, the hose is securely fixed.

The fixing state of the connector 42 will be described with reference to FIGS. 2 and 3. Figure 2 and Figure 3 is a cross-sectional view showing the operating state of the hose-connector coupling device of the present invention showing the state before and after coupling, respectively.

As in the above description, the connector 42 is also housed in the connector support 34 with the hose 44 fixed. In the figure, the nut of the head of the connector 42 is fixed by the bolt 36, and a part of the opposing part protrudes outward. In this state, the connector support 34 protrudes in the state moved to the upper side along the long hole 40. In addition, the handle 12 is also partly opened rather than completely closed. Thus, when the hose 44 is fixed by the hose housing 28 and the connector 42 is fixed by the connector support 34, the handles 12 are pushed inward in the direction of the arrow to lift the fixing part 14. They are combined facing each other with their axes.

When the protruding end of the connector 42 is seated in the hole of the hose 44, the connector 42 is fully engaged with the hose 44 by further applying force. In this case, the force applied to the handle 12 may increase the force applied to the connector 42 and the hose 44 by adjusting the length of the handle 12, and thus may be easily coupled to each other even with a small force. . As the force is applied to the connector 42 and the hose 44, the pin 38 fixed to the connector support 34 moves along the long hole 40 to disperse the force applied excessively. When the force is applied to the connector support 34, the movement is limited by the guide pin 30, so that the connector support 34 is not separated. This operating state is shown in FIGS. 2 and 3.

Referring to the working relationship of the hose-connector coupling device of the present invention having the structure as described above are as follows.

In order to couple the hose and the connector, the prepared connector 42 is inserted into the connector support 34 and fixed. Thus, the hose 44 for fitting the connector in the state in which the connector 42 is fixed is inserted into the hose storage part 28 and fixed. The hose housing 28 may be configured by combining the outer cover 24 and the inner cover 26.

When the connector 42 and the hose 44 are prepared as shown in FIG. 2, the two handles 12 are pushed in the direction of the arrow so that the connector 42 and the hose 44 approach each other about the fixing part 14. do. When approaching, the force of the hose 44 and the end of the connector 42 are aligned, and then further force is applied to each other. Therefore, the connector 42 and the hose 44 can be easily coupled in one coupling operation. After the connector 42 and the hose 44 are coupled, the nut part of the connector 42 is separated from the connector support 34 and the inner cover 26 and the outer cover 24 which also support the hose 44 are removed. Release the hose (44) to complete the joining work is completed.

In applying the apparatus of the present invention, it is apparent that the size of the hose housing 28 and the connector support 34 can be applied to all hoses and connectors according to the size of the hose and the size of the connector.

According to the present invention as described above can be easily inserted into the hose connector to be fitted to the end of the hose in order to connect the hose used in the hydraulic or pneumatic device, etc. can increase the installation work efficiency, do not grease the inside of the hose By not increasing the durability, there is an effect that can be accurately combined at a strong pressure. It is evident that the device of the present invention, however, can be applied not only for use in oil and pneumatic devices but also for the combination of different types of hoses.
