[0019] The following will provide a clear and complete description of the technical solution of the present utility model in conjunction with the accompanying drawings and specific embodiments. Figure 1-7As shown, a curtain built-in mounting frame includes a base 4, a buckle cover 3 buckled with the base 4, and a pull rope fixing member 30 is set on either the base 4 or the buckle cover 3; the buckle cover 3 is plate-shaped, and a card slot 31 is set on the left side of the lower surface of the buckle cover 3, and a limit plate 32 is set on the right side; the length direction of the card slot 31 is the left-right direction; the base 4 is a box body with an upper end opening, a pull rope outlet 41 is set on the left side wall of the base 4, a fixing hole 40 is set on the base 4, and a card plate 42 is set on the base 4 at the position corresponding to the card slot 31. When the buckle cover 3 is buckled with the base 4, the card plate 42 is set in the card slot 31, and the card plate 42 is located above the bottom plate of the card slot 31; the card slot 31 and the limit plate 32 are clamped in the box body of the base 4. In the utility model, the length direction of the base 4 is the left-right direction. The width direction is the front-back direction. The limit plate 32 limits the buckle cover 3 from moving rightward in the box body of the base 4, and the card slot 31 limits the buckle cover 3 from moving rightward and upward in the box body. In the structure of the utility model, the opening direction of the card slot 31 can be forward or backward, and the card slot 31 can also be a through slot, and no opening surface is set except for the left and right ends. If the opening of the card slot 31 is downward, the width of the lower opening of the card slot 31 is smaller than the width of the card slot 31. In short, the card slot 31 needs to have a bottom plate to prevent the card plate 42 of the base 4 from detaching in the up and down directions. The card slot 31 and the card plate 42 can be flat plates, or they can have a certain inclination in the front and back directions; the shape of the cross section can be rectangular, circular or other shapes. The four sides of the box body can be integral, or there can be gaps or intervals. The four sides of the box body can be used as long as they can play a role in limiting the position of the buckle cover 3. The card slot 31 here is stuck in the box body of the base 4, and the left side of the card slot 31 can be in contact with the left wall of the box, or a plate can be set on the right side of the card slot 31, or the card slot 31 is directly a blind hole with a bottom on the right side, and the right end of the card plate 42 and the limit plate 32 are limited to prevent the buckle cover 3 from moving to the left. Whether the mounting frame of the utility model is installed horizontally, vertically, or tilted on the window frame, after the pull rope 1 is stressed, no matter how the force direction changes, even if elastic deformation occurs between the buckle cover 3 and the base 4, the buckle cover 3 and the base 4 will not be separated, ensuring the stability of the pull rope 1 and the mounting frame.

[0020] The card slot 31 includes a bottom plate arranged below the buckle cover 3 and a vertical plate connecting the bottom plate and the lower surface of the card slot 31; two card slots 31 are arranged at the front and rear of the lower surface of the buckle cover 3; two card plates 42 are correspondingly arranged on the base 4; the space between the two card slots 31 is connected to the pull rope outlet 41. The shape of the card slot 31 can be L-shaped, or can be a mouth shape, or an inverted T shape. The space between the two card slots 31 and the pull rope outlet 41 is left for the pull rope 1 to pass through. Of course, only one card slot 31 or more than two card slots 31 can also be set. Preferably, the length of the card slot 31 does not exceed half of the length of the buckle cover 3, so as to facilitate the installation of the buckle cover 3 on the base 4. Each card slot 31 can have one vertical plate or multiple vertical plates, which can be set according to needs.

[0021] The pull rope fixing part 30 is arranged on the lower surface of the slot 31. The pull rope fixing part 30 is an inverted T-shaped protrusion arranged on the lower surface of the slot 31. The inverted T-shaped protrusion includes a vertical plate connected to the slot 31 and a horizontal plate located below the vertical plate. The pull rope 1 is sleeved on the vertical plate. The pull rope 1 passes through the space between the two slots 31 and passes out of the mounting frame from the pull rope outlet 41. The pull rope fixing part 30 is arranged on the right side of the slot 31, and there is a certain distance between the pull rope fixing part 30 and the slot 31. Of course, the pull rope fixing part 30 can also be arranged in the base 4. Whether the pull rope fixing part 30 is arranged on the base 4 or the buckle cover 3, it is within the protection scope of the present utility model. The pull rope fixing part 30 can also be in other shapes, as long as it can play the role of fixing the pull rope 1.

[0022] After the base 4 and the buckle cover 3 are buckled together, the right end of the buckle cover 3 away from the pull rope outlet 41 exceeds the base 4 in the length direction or the width direction. When disassembling, the buckle cover 3 and the base 4 can be separated by a certain distance by pulling the part of the buckle cover 3 that exceeds the base 4 upward by hand or tools, so as to disassemble the buckle cover 3. The shape of the buckle cover 3 of the utility model can facilitate the disassembly of the mounting frame.

[0023] The left side of the limit plate 32 is an inclined surface, and the angle between the left side of the limit plate 32 and the lower surface of the adjacent buckle cover 3 is an obtuse angle. During installation, the buckle cover 3 enters the box body of the base 4 from right to left, and the card slot 31 of the buckle cover 3 is aligned with the card plate 42 of the base 4 and moves to the left. During the movement, the left side of the limit plate 32 of the buckle cover 3 contacts the right side wall of the box body of the base 4. The left side of the limit plate 32 is set to an inclined surface shape, which can make it easier for the limit plate 32 on the right side of the buckle cover 3 to enter the box body. The inclined surface can be an inclined plane, or it can be a curved surface such as an arc surface.

[0024] In addition, the material of the buckle cover 3 and the base 4 of the utility model can be plastic or other materials with a certain elastic deformation, which facilitates the buckle cover 3 and the base 4 to buckle and disassemble. The mounting frame of the utility model can be installed horizontally or vertically. When installed horizontally, the direction of the pull rope 1 can be as shown in the attached figure. The pulling force of the pull rope 1 is mainly upward and left. When installed vertically, the pulling direction of the pull rope 1 is mainly consistent with the length direction of the base 4. The structure of the utility model can be applied to various installation methods.

[0025] During specific implementation, during installation: first select the location for the installation base according to the specifications of the curtain. Use the self-tapping screws 2 to fix the base 4 to the window frame through the fixing holes 40. After adjusting the length of the pull cord 1, hang it on the pull cord fixing piece 30 of the buckle cover 3, and pull it out from between the two slots 31. Push the buckle cover 3 into the box body of the base 4 from right to left at an angle, align the slot 31 of the buckle cover 3 with the card plate 42 of the base 4 and move until the limit plate 32 of the buckle cover 3 is stuck in the box body of the base 4, and the installation is complete. When disassembly is required, pull the buckle cover 3 upwards beyond the base 4 by hand or with a tool to separate the buckle cover 3 and the base 4 by a certain distance, thereby disassembling the buckle cover 3.

[0026] The technical features of the above-mentioned embodiments can be combined arbitrarily, and as long as there is no contradiction in the combination of these technical features, they should be considered as the scope of this specification. Without departing from the overall concept of the utility model, the technical solution of the utility model and the equivalent replacement or change, as well as the changes and improvements made, should also be regarded as the protection scope of the utility model.
