The cotton thread 88 serves to guide the water in the water receiving tank 81 into the lower end of the knock pin 82 more quickly so that the lower end of the knock pin 82 absorbs the water more quickly to be softened.

Preferably, the knock-out pin 82 is made of PVA collodion.

PVA collodion is commonly used on collodion mops, has the characteristics of good water absorption and softness after water absorption and dryness and hardness after water loss, and is particularly suitable for being applied to the invention; that is, when the knock pin 82 made of PVA collodion is in a dry state, it is relatively hard, and when the lock pin 71 moves to a position where it contacts, it pushes the lock pin 71, so that the lock pin 71 moves down axially and gets stuck into the lock hole 61, and when it absorbs water, it becomes soft, and at this time, under the action of the tension spring 85 and the first knock pin compression member 83 and the second knock pin compression member 84, it is compressed, so that it cannot push the lock pin 71 any more, the lock pin 71 moves up axially under the action of the second spring 72, and finally the lower end of the lock pin 71 (i.e., the movable portion 712 of the lock pin 71) is separated from the lock hole 61, so that the lock pin 71 is unlocked; after the knock pin 82 is dried, it returns to the hard state and protrudes again relative to the lower surface of the holder plate 3, so that when the lock pin 71 is again in contact with the knock pin 82, the knock pin 82 can push the lock pin 71 to move down axially.

Preferably, referring to fig. 4 and 10, the side wall of the bottom of the water receiving tank 81 is provided with a fine hole 811, and the fine hole 811 enables the water in the water receiving tank 81 to be discharged at a fine flow rate, so as to: after the rain stops, water in the water receiving tank 81 can be drained gradually, so that the ejector pin 82 can be dried as soon as possible and then is restored to the hard state, otherwise, the water in the water receiving tank 81 cannot be drained all the time, and the ejector pin 82 is wet all the time and is in the soft state all the time.

Preferably, referring to fig. 4, the top of the locking pin 71 is an arc-shaped surface, and the bottom of the top pin 82 is also an arc-shaped surface. Thus, when the lock pin 71 moves into contact with the knock pin 82, the lock pin 71 can smoothly move downward in the axial direction along with the contact of the two arc-shaped surfaces.

Preferably, in order to facilitate the movement of the skylight 2 from the room, a handle 22 is further provided at the bottom of the skylight 2, the handle 22 being located at the front side of the bottom of the skylight 2, see fig. 3; since the skylight 2 is arranged above the roof 1, in order to facilitate the movement of the skylight 2 by holding the handle 22 from the indoor, the inventor also provides a slot 13 on the roof 1, the position of the slot 13 corresponds to the position of the handle 22, the slot 13 extends along the front-back direction of the roof 1, see fig. 2, and the length of the slot 13 is long enough to ensure that the skylight 22 can be moved from the closed state to the fully open state when holding the handle 22 by hand.

Preferably, the number of the manual unlocking devices 5 and the locking plates 6 is two, and the two manual unlocking devices 5 and the locking plates 6 are distributed at the left and right sides of the slot 13 of the roof 1 at intervals, see fig. 2; of course, the number of the locking devices 7 is also two, and the two locking devices 7 correspond to the positions of the two locking plate 6, and can be respectively matched with the two locking plates 6 to achieve the purpose of locking, see fig. 3; meanwhile, the number of the water-encountering automatic unlocking devices 8 is two, and the two water-encountering automatic unlocking devices 8 are respectively positioned right above the two lock catch plates 6; with such a structure, when the skylight 2 is in a fully opened state, two sets of locking plates 6 and locking devices 7 are matched to lock the skylight 2, so that the skylight 2 can be locked more stably.

The working principle of the invention is as follows:

when the skylight 2 is in a closed state and the skylight 2 needs to be opened, the handle 22 is held from the indoor space, then the handle 22 is dragged along the direction of the slot 13, so that the skylight 2 can be moved to an opened state, and the skylight 2 can be locked and maintained in a completely opened state until the lock pin 71 at the front end of the skylight 2 is clamped into the lock hole 62;

then, when the skylight 2 needs to be manually closed, the bottom end of the lock pin 71 (i.e., the movable part 712 of the lock pin 71) is pushed away from the lock hole 61 by pressing the cap 511 of the button 51 with a hand, so that the skylight 2 is unlocked, and after the skylight 2 is unlocked, the skylight 2 moves to the side close to the skylight hole 11 along the roller track 4 under the action of gravity until the rear side of the skylight 2 collides with the first spring 92, the skylight 2 stays down, and the skylight 2 is in a completely closed state;

when the skylight 2 is in the opened state, rain water falls into the water receiving tank 81 when raining occurs, so that the top pin 82 is wetted, and since the top pin 82 is made of PVA collodion, the wetted top pin 82 is softened, and after the top pin 82 is softened, under the action of the tension spring 85 and the first and second top pin compression members 83 and 84, the top pin 82 is compressed (see fig. 10), i.e., the lower end of the top pin 82 is retracted into the through hole 31, so that the top pin 82 cannot push the lock pin 71 any more, the lock pin 71 is moved upward axially under the action of the second spring 72, and then the bottom end of the lock pin 71 (i.e., the movable portion 712 of the lock pin 71) is disengaged from the lock hole 61, and after the disengagement, the lock pin 71 is unlocked, so that the roller 21 of the skylight 2 moves along the roller rail 4 to the lower slope of the skylight 1 under the action of gravity until the rear side of the skylight 2 collides with the first spring 92, the skylight 2 stays, and the skylight 2 is in a completely closed state at the moment, as shown in fig. 8 to 10, so that the automatic window closing function in rainy days can be realized; after the rain stops, after all the water in the water receiving tank 81 is drained from the holes 811 at the bottom, and meanwhile, after the ejector pin 82 is naturally dried, the ejector pin 82 returns to a hard state and protrudes relative to the lower surface of the support plate 3 again, so that when the lock pin 71 is contacted with the ejector pin 82 again, the ejector pin 82 can push the lock pin 71 to move downwards axially, and the function of automatically closing the window in the rainy day can be started again.
