In addition, the cap CP is provided in the case CA so that oil can enter and exit the cap CP, which can also be applied in the same manner as in the prior art, and detailed illustration and description thereof will be omitted.

In the present invention, as described above, the drain pin 100 is detachably gripped by the gripper 200 . According to the present invention, the drain pin 100 is usually firmly fixed, and can be easily removed by a worker if necessary, thereby improving work efficiency.

The gripper 200 includes a plate-shaped gripper body 210 and a first recess 220 and a second recess 230 formed in the gripper body 210 . The gripper body 210 has a plate shape and extends downward. The first recessed portion 220 is formed by recessing a portion of the side of the gripper body 210 . The second recessed portion 230 is formed on the first recessed portion 220 . That is, the second recessed portion 230 is disposed on the first recessed portion 220 based on the height direction.

The drain fin 100 includes a bar-shaped drain fin body 110 and a pair of coupling plates 160 formed on the drain fin body 110 . The coupling plates 160 are spaced apart from each other by a predetermined distance, and the gripper body 210 is inserted between the coupling plates 160 . A first protrusion 120 and a second protrusion 130 are formed on the pair of coupling plates 160 . The first protrusion 120 is formed to protrude from the opposite side of the pair of coupling plates 160 . The second protrusion 130 is also formed to protrude from the opposite side of the pair of coupling plates 160 . At this time, the first protrusion 120 is inserted into the first concave groove 220 , and the second protrusion 130 is inserted into the second concave groove 230 . That is, the first protrusion 120 is disposed below the second protrusion 130 . The drain pin body 110 rotates in a state in which the first protrusion 120 is inserted into the first recess 220, and this will be described separately.

The first protrusion 120 protrudes in a hemispherical shape, and the first recess 220 is recessed in a hemispherical shape so that the first protrusion 120 is inserted. With this configuration, the first protrusion 120 is rotatably provided in the state inserted into the first concave portion 220 . To this end, it is natural that the diameter of the first protrusion 120 should be smaller than the diameter of the first concave portion 220 .

The second protrusion 130 has a smaller width than the first protrusion 120 and protrudes in a box shape. In addition, the second protrusion 130 is arranged in the height direction for the second groove 230 to be inserted. As shown in FIG. 2 , the second recessed portion 230 is disposed on the upper side of the first recessed portion 220 and is formed to have a recessed section of a specific width in the vertical direction. The second protrusion 130 is inserted into the second concave groove 230 .

With this configuration, the first protrusion 120 is rotated in a state in which the first protrusion 120 is inserted into the first concave groove 210 , whereby the drain pin body 110 is interlocked and rotated. In addition, when the drain pin body 110 rotates, the second protrusion 130 is inserted into the second concave groove 230 to stop the rotation. That is, the rotation is stopped the moment the second protrusion 130 is inserted into the second concave groove 230 while the drain pin body 110 rotates. This is an accurate point for removing the drain pin body 110 . With this configuration, the user can know that the drain pin body 110 has reached the correct position.

Therefore, as described above, the drain pin is folded and packaged to reduce the packaging space during logistics, and then the drain pin is used upright in actual use. At this time, according to the present invention, it is possible to accurately erect the drain pin.

In addition, in order to easily remove the drain fin 100 , the drain fin 100 may include a first through hole 140 and a second through hole 150 formed in the drain fin body 110 , , the fixing pin FP passes through the through hole N1 of the drain nipple N and then passes through the first fixing hole 140 so that the drain pin 100 is fixed. In addition, the insertion pin 300 is inserted into the second through hole 150 , and the operator can remove the drain pin 100 more conveniently using the insertion pin 300 , and the operator can be contaminated with oil. it can be prevented

That is, a portion of the second through hole 150 is formed to be exposed from the drain nipple N, and the insertion pin 300 is inserted from the outside. At this time, the insertion pin 300 has a bar shape and has a shape in which the diameter decreases toward the drain pin 100 . Accordingly, as the insertion pin 300 is inserted, the drain pin 100 moves downward and is removed. In other words, the tip of the insertion pin 300 may be inserted into the second through-hole 150 partially exposed from the drain nipple N due to a relatively small diameter. At this time, when the insertion pin 300 is additionally inserted, the upper surface of the insertion pin 300 comes into contact with the bottom surface of the drain nipple N because the diameter of the insertion pin 300 increases. In this state, when the insertion pin 300 is additionally inserted, the diameter of the insertion pin 300 continues to increase, so the drain pin 100 descends. is removed from With this configuration, the drain pin 100 can be removed more conveniently, and since the removed drain pin 100 is fixed to the insertion pin 300, it does not fall freely and there is no risk of oil splashing to the outside.

In addition, as shown in FIG. 5 , the operator's hand grips the insertion plate 300 to be spaced apart from the drain pin 100 by a predetermined distance in the horizontal direction. Due to this configuration, even if the oil leaks, the hands of the operator are separated from each other, so that it is not misunderstood.

Although the present invention has been described in detail through specific examples, this is for the purpose of describing the present invention in detail, and the present invention is not limited thereto. It is clear that the modification or improvement is possible.

All simple modifications and variations of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be clarified by the appended claims.
