(13) Preferably, as shown in FIG. 2, the inner frame further includes a second connecting portion which is also plate-shaped, the second connecting portion is disposed opposite to and parallel to the plate-shaped connecting portion 11, and the second connecting portion is disposed adjacent to the glass plate 2 and fixed to the water baffle 301, for example, fixedly connected to the water baffle 301 by a bending portion.

(14) Further, as shown in FIGS. 1 and 2, there is provided a nail-free and glue-free skylight, which includes an outer profile frame 1, a glass plate 2, and an inner profile frame 3, in particular, the glass plate 2 is disposed between the outer profile frame 1 and the inner profile frame 3, the outer profile frame 1 is formed by splicing a plurality of outer profiles, and the inner side surface of the outer profile frame 1 is integrally formed with a first fixing piece 4. In this embodiment, there are four outer profiles, so that the spliced outer profile frame 1 is rectangular. In other embodiments, the spliced outer profile frame also can be triangular, regular polygonal, etc. The glass plate 2 is made of glass, and may also be made of other daylighting materials. The inner profile frame 3 includes an annular water blocking portion, and the outer side surface of the annular water blocking portion is integrally formed with a second fixing piece 5, and the first fixing piece 4 is in snap-fit engagement with the second fixing piece 5. In particular, the shape of the outer profile frame 1 matches with that of the inner profile frame 3.

(15) The first fixing piece 4 in this embodiment includes two connecting plates which are parallel to each other, and the two connecting plates and the outer profile frame 1 form a concave portion. The second fixing piece 5 is a convex portion, the convex portion matches the concave portion, and the convex portion is snap-fitted into the concave portion, so as to connect the water blocking portion and the outer profile frame 1 together. In other embodiments, the first fixing piece 4 is a convex portion, and the second fixing piece 5 is a concave portion, and other similar structures may also be used to connect the annular water blocking portion and the outer profile frame 1 together.

(16) The inside of the second fixing piece 5 is a hollow structure, and the weight of the second fixing piece 5 can be reduced on the premise of ensuring the structural strength of the second fixing piece 5. The surface of the second fixing piece 5 is integrally formed with a sliding rail 6, and a heat insulating strip 7 is slidably connected to the sliding rail 6. The heat insulating strip 7 slides into the end portion of the second fixing piece 5, so that the heat insulating strip 7 can be mounted more easily, and the heat insulating strip 7 can reduce the heat outside the room from entering the room through the outer profile and the inner profiles. A guide groove 8 is formed in the first fixing piece 4 and can guide the second fixing piece 5 to be snap-fitted into the first fixing piece 4, thereby making it easier to assemble the outer profile to the annular water blocking portion and the glass plate 2.

(17) As shown in FIGS. 2 and 3, the annular water blocking portion is formed by bending the water baffle 301, the junction of the head end and the tail end of the water baffle 301 directly faces any of the outer profiles, that is, a junction of the two ends of the water baffle 301 is not located at the collision corner of the annular water blocking portion. The head and tail ends of the water baffle 301 may be connected together by welding or may be directly abutted against. The annular water blocking portion is formed by bending one water baffle 301, so that the inner profile frame 3 is easy and quick to process and assemble. Further, the annular water blocking portion is integrated at the collision corner, so that rainwater can be reduced from entering the room from the collision corner of the annular water blocking portion, and the waterproof effect of the skylight is improved. A gap is left between adjacent second connecting portions 5, so that rainwater can enter the skylight through the collision corner of the outer profile frame 1, and flow outside the room from the gap of the second fixing pieces 5, that is, a channel is provided for drainage of the rainwater.

(18) The water baffle 301 is inserted with a first seal 9 abutting against the glass plate 2, the first seal 9 matches with the bent water baffle 301, and the first seal 9 is a rubber sealing strip with a U-shaped cross section. The first seal 9 is sleeved on the water baffle 301, which can reduce the occurrence of falling-off when the outer profile is assembled on the annular water blocking portion. Furthermore, the first seal 9 abuts on the glass plate 2, thereby further improving the waterproof effect of the skylight. The surface of the water baffle 301 is integrally formed with the anti-slip rib 10, and the anti-slip rib 10 can reduce the first seal 9 from falling off the water baffle 301.

(19) The skylight further includes a window frame 13, the window frame 13 is located below the annular water blocking portion, and the outer profile frame 1 is movably connected to the window frame 13 via a mounting member 14. Like the conventional window frame 13, the window frame 13 in this embodiment is also mounted on the roof, and the window frame and the window sash together constitute a window. The mounting member 14 may be a hinge or a gemel, and the outer profile frame 1 can be reversed by the hinge or the gemel, thereby realizing the opening or closing of the window. In particular, the junction between the head and tail ends of the water baffle 301 is located on the side of the window close to the mounting member 14.

(20) The water baffle 301 is provided with a connecting portion 11 on a side away from the second fixing piece 5, the connecting portion 11 is a horizontal plate, and the connecting portion 11 is integrally formed on a side surface of the water baffle 301. The lower surface of the connecting portion 11 abuts against the upper surface of the window frame 13, and the lower surface of the water baffle 301 is lower than the upper surface of the window frame 13. The protruding portion of the water baffle 301 may play a role of guiding water, that is, guiding rainwater entering the skylight from the collision corner of the outer profile frame 1. The upper end of the window frame 13 is mounted with a second seal 15, and the second seal 15 is a rubber sealing strip with a U-shaped cross section. By means of the second seal 15, rainwater can be reduced from entering the room between the window frame 13 and the connecting portion 11.

(21) As shown in FIGS. 3 and 4, the inner frame further includes a mullion 12, and the mullion 12 is mounted on the water baffle 301 via the connecting portion 11. The glass plate 2 in this embodiment is pressed against the support strip and the first seal 9. The second seal 15 is mounted on the window frame 13, and when the skylight is closed, the connecting portion 11 is pressed against the second seal 15. The mullion 12 can increase the structural strength of the skylight. Most of the existing skylight is opened and closed by an air cylinder. The piston rod of the air cylinder is mounted on the mullion 12, so that the damage of the skylight is reduced.

(22) An corner brace (not shown in the figure) is mounted between two adjacent outer profiles, the corner brace is in an L shape, and two ends of the corner brace are respectively inserted into a hollow part of the outer profiles. The corner brace connects the adjacent outer profiles, so that the outer profiles are assembled on the annular blocking portion and the glass plate 2 more firmly.

(23) In this embodiment, the annular water blocking portion is formed by bending a water baffle 301, and the second fixing piece 5 and the connecting portion 11 are integrally formed on both sides of the water baffle 301. Furthermore, the bottom of the water baffle 301 protrudes from the lower surface of the second fixing piece 5 and the connecting portion 11, respectively. The protruding portion of the water baffle 301 may play a role of guiding water, that is, guiding rainwater entering the skylight from the collision corner of the outer profile frame 1. If the inner profile frame 3 formed by the water baffle 301, the second fixing piece 5 and the connecting portion 11 is integrally formed, the processing is difficult and the cost is high. When the inner profile frames 3 with different sizes are processed, different dies are needed, and the processing cost is further increased. If the inner profile frame 3 formed by the water baffle 301, the second fixing piece 5 and the connecting portion 11 is formed by welding at the collision corner, and the production process of the skylight is more complicated. The waterproof effect at the welding position of the inner profile frame 3 is poor, particularly after a period of time is used, the inner profile frame 3 is easily cracked at the welding position.

(24) Further, there is provided a method for manufacturing a nail-free and glue-free skylight, and the method includes the following steps.

(25) Step S1, processing an outer profile: cutting two ends of the outer profile, so that four outer profiles are spliced into an outer profile frame 1.

(26) Step S2, processing an inner profile: cutting off the second fixing piece 5 at a portion of a water baffle 301 to be bent, and cutting the connecting portion 11 at a portion of the water baffle 301 to be bent, so that the connecting portion 11 is spliced into a shape matched with the outer profile frame 1, after bending the water baffle 301.

(27) Step S3, molding the inner profile frame 3: bending the water baffle 301 to make two ends of the water baffle 301 abut against each other, and mounting a first seal 9 on the water baffle 301.

(28) Step S4, assembling: placing the inner profile frame 3 on an operation table, placing the glass plate 2 on the inner profile frame 3, and then inserting the outer profile from a side surface of the inner profile frame 3 and the glass plate 2, so that the second fixing piece 5 is snap-fitted into the first fixing piece 4.

(29) The annular water blocking portion is formed by bending one water baffle 301, so that the inner profile frame 3 is easy and quick to process and assemble. Further, the annular water blocking portion is integrated at the collision corner, so that rainwater can be reduced from entering the room from the collision corner of the annular water blocking portion, and the waterproof effect of the skylight is improved. Before the step S4, a heat insulating strip is provided between the second fixing piece and the first fixing piece. In the step S4, an corner brace is inserted between two adjacent outer profiles, and the outer profiles are abutted against the corner brace by an compression device. The corner brace connects the adjacent outer profiles, so that the outer profiles are assembled on the annular blocking portion and the glass plate 2 more firmly. In particular, the compression device may be an existing compression device.

(30) The above are the preferred embodiments of the application, and do not limit the scope of protection of the application accordingly. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the application shall be covered by the scope of protection of the application.
