Here, the meaning of bimetal means that two kinds of materials having different linear expansion coefficients are bonded to each other, and when a temperature change occurs, a bimetal made of two kinds of materials is bent in a certain direction.

In this case, the large coefficient of linear expansion means that the degree of bending is large when the change in temperature is large.

For example, when iron and copper are joined together and heated, the linear expansion coefficient of copper is higher than that of iron at high temperatures, and thus bending occurs in the direction in which iron is provided. On the contrary, at low temperatures, iron and copper, i. It will return to the form of.

In detail, the first safety part 100, the second safety part 200, and the third safety part 300 may be made of a material having a low coefficient of linear expansion, as shown in FIG. 10. The coefficient of linear expansion is relatively relatively to each of the outer circumferential surface of the first safety part 200 adjacent to the insertion groove 120 and the inner circumferential surface of the second safety part 200 adjacent to the third safety part 300 inserted into the second insertion groove 220. The high bimetal member 250 may be provided.

For example, the first safety part 100, the second safety part 200, and the third safety part 300 may be made of a plastic material, and the bimetal member 250 illustrated in FIG. 10 may be made of a metal material.

Accordingly, when the second safety part 200 is inserted into the first insertion groove 120 of the first safety part 100, the first safety part 100 made of plastic and the metal bimetal member 250 are provided on the outer circumferential surface thereof. Since the second safety part 200 is located adjacent to each other, the frictional force is considerably lowered compared to the surfaces of which the adjacent surfaces are made of the same material, and each of the first safety part 100 and the second safety part 200 when heat is generated due to friction. The degree of bending due to thermal deformation may be minimized, and the metal bimetal member 250 may be prevented from spreading outward.

In order to perform the same function, the third safety part 300 inserted into the second insertion groove 220 of the second safety part 200 is made of plastic, and a metal material is formed on the inner circumferential surface of the second insertion groove 220. Since the bimetal member 250 is provided, the frictional force may be remarkably lowered as compared with the surfaces of the second safety part 200 and the third safety part 300 which are adjacent to each other.

In addition, since the second safety part 200 has a property to be bent inward by the bimetal member 250 having a different coefficient of linear expansion, the first safety part 100 and the second safety part 200 may be caused by a force to be bent inwardly. And the third safety part 300 minimizes the force to be opened to the outside, and pressurizes inward to delay the rotation speed when the door 20 is rotated, thereby preventing the door 20 from being closed with a fast and strong force. have.

The vent hole 420 allows the inside and the outside of the cover 410 to communicate with each other. The door 20 is rotated so that the second safety part 200 moves toward the first insertion groove 120 of the first safety part 100. When the slide is moved, the air filled in the first insertion groove 120 is discharged to the outside through the vent hole 420, thereby reducing the speed of the slide movement of the second safety part 200, the door 20 It can prevent rotation by a strong force.

In other words, while the second safety part 200 is slid to the side of the first insertion groove 120 of the second safety part 200, one end of the second safety part 200 is formed with the first insertion groove 120. When adjacent to the inner circumferential surface of the first safety part 100, the first safety part 100 is instantaneously discharged at a high pressure through the vent hole 420 filled with the air filled in the first insertion groove 120 It is possible to reduce the slide movement speed of the door 20, that is, the rotation speed of the door 20.

Thus, the occurrence of a safety accident can be prevented in advance due to a decrease in the rotation speed of the door 20.

At this time, the vent hole 420 may be configured to enable the adjustment of the size formed.

For example, the cap is rotatably fastened to the cover 410 by thread coupling, and forms a through hole in a portion of the upper side of the cap, and as the cap is rotated, the cover 410 is fastened to the cap. By adjusting the area in which the through holes formed in the cap overlap, the size of the through holes, that is, the size of the vent hole 420 is adjusted to give a damping effect to the second safety part 200, so that the door 20 is It can prevent being rotated with strong force.

According to a design condition, the vent hole 420 may be formed to correspond to a portion where the first insertion groove 120 is formed, as shown in FIG. 11, but the second insertion groove of the second safety part 200 is formed. It may be formed to correspond to the portion where the 220 is formed.

Accordingly, when the third safety part 300 rotates to the second insertion groove 220 side of the second safety part 200, the air filled in the second insertion groove 220 of the second safety part 200 is vented 420. By discharging at a high pressure through the), the shock can be absorbed so that the rotation of the third safety part 300 from the second safety part 200 is performed slowly.
