Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 A blind installation and fixing structure in this embodiment includes a mounting plate 1, a blind body 2 is arranged on the lower surface of the mounting plate 1, a first mounting mechanism 3 is arranged on the mounting plate 1, which can install the blind without damaging the door frame, and maintain the integrity of the door frame while installing the blind, thereby improving the aesthetics of the door frame after removing the blind, and a second mounting mechanism 4 is arranged on the mounting plate 1 for adapting to a larger door frame, so that the blind can still be installed when the door frame is wider, and the integrity of the door frame can be ensured.

[0022] The shape of the mounting plate 1 is a rectangular parallelepiped with a hollow interior, and the length of the mounting plate 1 is adapted to the width of the blind body 2 .

[0023] See also Figure 2In order to maintain the integrity of the door frame while installing the curtain and improve the aesthetics of the door frame after removing the curtain, the first installation mechanism 3 in this embodiment includes a threaded block 301, and the threaded block 301 is rotatably connected to the left side of the mounting plate 1 through a bearing. The inner side of the threaded block 301 is threadedly connected with a threaded rod 302. The mounting plate 1 is placed against the top of the door frame and the threaded block 301 is rotated. The rotation of the threaded block 301 drives the inner threaded rod 302 to move. A first fixing plate 303 is fixed to one end of the threaded rod 302. The movement of the threaded rod 302 drives the first fixing plate 303 to move. The other end of the threaded rod 302 penetrates and extends to the inside of the mounting plate 1, and a first rack 304 is fixed to the outer side. The movement of rod 302 will also drive the first rack 304 to move. The lower surface of the first rack 304 is meshed with a gear 305. The first rack 304 drives the gear 305 to rotate. The gear 305 is rotatably connected to the back side of the mounting plate 1 through a bearing. The outer side of the gear 305 is meshed with a second rack 306. The rotation of the gear 305 drives the second rack 306 to move. A connecting rod 307 is fixed to the upper surface of the second rack 306. The second rack 306 drives the connecting rod 307 to move. The other end of the connecting rod 307 passes through and extends to the right side of the mounting plate 1, and is fixed with a second fixed plate 308. The connecting rod 307 drives the second fixed plate 308 to move. A limiting component is set on the threaded rod 302.

[0024] In this example, the position of the first rack 304 and the position of the second rack 306 are symmetrically distributed through the central axis of the gear 305, so that the movements of the first rack 304 and the second rack 306 are synchronized, and the movement direction of the second rack 306 is opposite to the movement direction of the first rack 304. The threaded rod 302 and the connecting rod 307 are located on the same straight line, and the first fixing plate 303 and the second fixing plate 308 are extended at the same time, which can support the left and right sides of the door frame. By tightening the threaded block 301, the curtain can be installed without opening a hole in the door frame.

[0025] It should be noted that the limiting assembly includes a connecting block 309, a sliding rod 310 is fixed to the left side of the connecting block 309, a limiting block 311 is fixed to the outer side of the threaded rod 302, the inner side of the limiting block 311 is slidably connected to the outer side of the sliding rod 310, the threaded block 301 drives the threaded rod 302 to move, the threaded rod 302 drives the limiting block 311 to move, the limiting block 311 slides on the sliding rod 310, and the sliding rod 310 can limit the angle of the limiting block 311, thereby preventing the threaded rod 302 from rotating due to the rotation of the threaded block 301, so that the threaded rod 302 can be prevented from rotating. The rod 302 can maintain normal movement. There are four connecting blocks 309, and two of them are in a group. They are symmetrically distributed on the left and right sides of the central axis of the mounting plate 1, so as to limit the movement range of the first fixed plate 303 and prevent the first rack 304 from detaching from the gear 305. There are two sliding rods 310 and two limit blocks 311, and they are respectively located between the opposite sides of the two groups of connecting blocks 309. The inner side of the right limit block 311 is fixed to the outer side of the connecting rod 307, so that the second rack 306 can remain stable and avoid detaching from the gear 305.

[0026] See also Figure 3 In order to install the curtain when the door frame is wide and ensure the integrity of the door frame, the second installation mechanism 4 in this embodiment includes a double-sided adhesive tape 401, one side of the double-sided adhesive tape 401 is bonded to the upper surface of the installation plate 1, and the other side of the double-sided adhesive tape 401 is bonded with a sealing tape 402, and the sealing tape 402 can protect the bonding surface of the double-sided adhesive tape 401 to prevent the bonding surface from losing its stickiness and affecting the stability of the curtain installation. An anti-stick coating 403 is fixed to the lower surface of the sealing tape 402, and the anti-stick coating 403 on the sealing tape 402 can prevent the sealing tape 402 from adhering to the double-sided adhesive tape 401, so that the sealing tape 402 can be easily torn off. After tearing off the sealing tape 402, the bonding surface of the double-sided adhesive tape 401 is bonded to the top of the door frame, and the curtain can also be installed without opening a hole in the door frame.

[0027] In this example, the length and width of the sealing tape 402 are respectively equal to the length and width of the double-sided adhesive tape 401, and the length and width of the double-sided adhesive tape 401 are respectively adapted to the length and width of the mounting plate 1, so that the mounting plate 1 and the door frame are more firmly bonded.

[0028] The working principle of the above embodiment is:

[0029] (1) When the width of the door frame at the curtain installation position is similar to the length of the mounting plate 1, the first mounting mechanism 3 can be used for installation. The mounting plate 1 is placed against the top of the door frame and the threaded block 301 is rotated. Under the limit of the limit block 311 and the slide rod 310, the rotation of the threaded block 301 can drive the inner threaded rod 302 to move. The movement of the threaded rod 302 drives the first fixed plate 303 to move. At the same time, the movement of the threaded rod 302 also drives the first rack 304 to move. The first rack 304 drives the gear 305 to rotate. The gear 305 drives the second rack 306 to move. The movement direction of the second rack 306 is opposite to that of the first rack 304. The second rack 306 drives the connecting rod 307 to move. The connecting rod 307 drives the second fixed plate 308 to move. The first fixed plate 303 and the second fixed plate 308 are extended at the same time, which can support the left and right sides of the door frame. The threaded block 301 is tightened, and the curtain can be installed without drilling a hole in the door frame.

[0030] (2) When there is a large difference between the width of the door frame at the curtain installation position and the length of the installation plate 1, it is difficult for the first fixing plate 303 and the second fixing plate 308 to extend to both sides of the door frame for support. At this time, the installation plate 1 is aligned with the position of the window, and then the sealing tape 402 is torn off. The sealing tape 402 can protect the bonding surface of the double-sided adhesive 401 to prevent the bonding surface from losing its adhesiveness and affecting the stability of the curtain installation. The anti-stick coating 403 on the sealing tape 402 can prevent the sealing tape 402 from adhering to the double-sided adhesive 401, thereby facilitating the tearing off of the sealing tape 402. After tearing off the sealing tape 402, the bonding surface of the double-sided adhesive 401 is adhered to the top of the door frame. Similarly, the curtain installation can be completed without drilling a hole in the door frame.
