Hereinafter, the present invention will be described in detail with reference to the drawings.

Fig. 1 is a schematic diagram of a male part 100 according to a temporal example of the present invention. The male part 100 includes a housing part 110, a piping part 120 and a locking part 130. The piping part 120 passes through the housing part 110. [ The male part 100 is installed on the mother body 300 and moves together with the mother body 300. In one embodiment, FIG. 8 discloses a male part 100 provided on a matrix 300.

The matrix 300 may be a bogie with ladle in which molten steel is taken. In the furnace, molten steel that melts pig iron, etc. is used to produce plate materials and steel materials of various shapes. Molten steel made in the furnace is accommodated in the ladle, moved to the place where the mold is installed, . Because of the high temperature and high risk of slag leakage, special attention should be paid to moving the ladle-laden bogie and tightening and disconnecting the pipe of the male and female parts at the final destination.

2 and 3 illustrate a female part according to an embodiment of the present invention. The female part 200 includes a centering unit 210, a carriage 220, a tension part 230, a guide part 240, and a rail part 250. The centering unit 210 is a portion into which the male part 100 is inserted and has a shape corresponding to the shape of the male part 100. [

On the rail part 250, the carriage 220 is movable in a direction parallel to the rail part 250, which is driven by the wheel 221 of the carriage part 220. The spring unit 211 connects the carriage unit 220 and the centering unit 210 and serves as a guide when the male unit 100 is inserted into the centering unit 210.

A locking device 212 is connected to the centering unit 210 and the locking device 212 is engageable with the locking part 130 of the male part 100.

When the male part 100 is inserted below the center of the centering unit 210, the centering unit 210 is lifted upward. When the centering unit 210 is lifted upward, the wheel 221 is also lifted upward, and the wheel 221 abuts against the guide portion 240 to impart resistance to the female portion 200. Also, when the male part 100 is disengaged, the guide part 240 and the wheel 221 abut against each other to impart a resisting force to the female part 200. [

The tension portion 230 presses the inclined surface 222 of the bogie portion 220 by elasticity to prevent the bogie portion 220 from being instantaneously accelerated.

The guide part 240 and the tension part 230 can be securely coupled to each other even if the male part 100 is shifted to the center of the centering unit 210 when the male part 100 and the female part 200 are engaged, And prevents the centering unit 210 from being accelerated by the impact of the male part 100 and the centering unit 210, thereby surely guaranteeing these defects.

Before the male part 100 and the female part 200 are engaged with each other, the locking device 212 abuts against the arm 213 connected to the locking device 212, And maintains the device 212 lifted upwards.

4 is a detailed view showing a positional relationship of the centering unit 210 according to an embodiment of the present invention. The centering unit 210 is suspended from the bogie portion 220 by the support of the spring portion 211. The centering unit 210 also includes a circumferential flat plate 215 and a flat plate 215 inserted between the two plates 261 of the receiving portion 260. The flat plate 215 can be moved between the two plates 261 by the elasticity of the spring portion 211 and the two plates 261 prevent excessive movement of the centering unit 210 Function. Since the centering unit 210 is movable between the two plates 261, the position of the centering unit 210 can be adjusted even if the center of the centering unit 210 and the insertion position of the male part 100 are slightly shifted.

5 is a view for explaining a state in which the tension portion 230 presses the inclined surface 222 of the bogie portion 220. Fig. The tension portion 230 positioned vertically is tilted obliquely after contact with the inclined surface 222 in accordance with the movement of the carriage after the connection of the curved portion 100. The resistive force is applied to the inclined surface 222, It is possible to prevent the female mold portion 200 and the male mold portion 100 from being separated from each other by the engagement impact when the mold 100 is engaged. In addition, the inclination of the inclined surface 222 serves to prevent instantaneous acceleration due to the tension force when the bogie 220 is released from the tension portion 230.

Fig. 6 shows that the bogie portion 220 includes the inclined surface 222 as a perspective view.

FIG. 7 illustrates a process in which a male part according to an embodiment of the present invention is engaged with a female part. The male part 100 is installed on the moving body 300 and moves together with the body 300. The male part 100 moving together with the mother body 300 is aligned with the centering unit 210 of the female part 200 provided on the outside of the mother body 300 and is moved by the moving force of the mother body 300 100 move the bogie unit 220 along the rail part 250 in a state aligned with the centering unit 210. When the male part 100 and the centering unit 210 advance along the rail part 250, the plate 214 and the arm part 213 are slid and finally the plate 214 and the arm part 213 are separated from each other . Thus, the locking device 212, which has been lifted up by the plate 214, descends downward and is automatically engaged with the locking part 130 of the male part 100. The wheel 221 of the bogie unit 220 may be fixed to the guide unit 240 to prevent the male part 100 and the centering unit 210 from falling off due to impact when the male part 100 and the female part 200 are engaged, And a resistance force is applied to the inclined surface 222 of the carriage 220 by abutting against the tension portion. The guide portion 240 may be made of a material capable of imparting a frictional force to the wheel 221, which is a member that elongates in the moving direction of the wheel 221. The tension unit 230 can apply a frictional force to the inclined surface 222 of the bogie unit 220 through a material having elasticity (for example, a spring or the like) A roller 231 having resistance may be disposed on the roller 230.

7 shows a state where the male part 100 and the female part 200 are engaged with each other and the male part 100 and the female part 200 are engaged after the lock part 130 and the lock device 212 are engaged with each other, To be separated arbitrarily.

In order to separate the male part 100 and the female part 200, the mother body 300 is moved in the direction opposite to the direction (A direction) in which the male part 100 is joined with the female part 200 (direction B). The male part 100 and the female part 200 are coupled and moved in the direction B by the combination of the lock part and the lock part, and the arm parts 213 come into contact with the plate 214, When the connected locking device 212 is lifted upward, the locking device 212 and the locking part 130 are disengaged and the male part 100 and the female part 200 can be separated from each other.

Therefore, according to the present invention, since the male part 100 and the female part 200 can be automatically engaged and separated by the movement of the mother body without directly intervening the operator, The quick coupler of the present invention does not have to stop the process at the time of fastening and separating the male part and the female part of the quick coupler of the present invention, The connection is efficient.
