[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0035] As Figures 1 to 9 ​​​As shown, the embodiment of the present application provides a ceiling curtain easy to assemble, which comprises a front frame 11, a left guide rail frame 13 and a right guide rail frame 14. The left guide rail frame 13 is provided with a first transmission box 4, and the right guide rail frame 14 is provided with a second transmission box 5. The opposite sides of the left guide rail frame 13 and the right guide rail frame 14 are provided with guide grooves. The two ends of the front frame 11 can be slid from the rear side of the left guide rail frame 13 and the right guide rail frame 14 into the guide grooves of the left guide rail frame 13 and the right guide rail frame 14, and then slid along the guide grooves to the front end of the left guide rail frame 13 and the right guide rail frame 14 to be buckled with the first transmission box 4 and / or the second transmission box 5. The present application provides a ceiling curtain easy to assemble, which changes the traditional U-shaped structure of the front frame, and does not need to be installed into parts before being fixed with the left and right guide rail frames. The front frame is connected and fixed with the transmission boxes on the left and right guide rail frames by being slid into the front end of the left and right guide rail frames, so that the installation mode is simplified, and the installation is simpler. Moreover, the whole frame of the ceiling curtain is not limited to being installed into the installation position of the ceiling after being pre-installed, so that the on-site installation is more flexible, and the later maintenance and disassembly are also simpler and more convenient.

[0036] As shown in the embodiment of the present application, Figure 10 , Figure 11 The specific structure of the first transmission box 4 is that the first transmission box 4 is further provided with a connecting part 401. The connecting part 401 is provided with an opening extending from the side wall of the connecting part 401 to the middle part of the connecting part 401 to form a buckle connecting part 41. The outer side of the connecting part 401 forms a guide surface 42 extending to the buckle connecting part 41. The connecting part 401 is provided with a buckle connecting part 41 for the front frame connecting wall 112 to be buckled. The connecting part 401 gradually increases in width from the lower side to the upper side. The buckle connecting part 41 is a recess extending from the side wall of the connecting part 401 to the middle part of the connecting part 401. The outer side of the connecting part 401 forms a guide surface 42 extending to the buckle connecting part 41. The connecting part on the connecting body has a guide surface. When the front frame is installed, the connecting arm of the front frame can be guided into the buckle connecting part along the guide surface on the outer side of the connecting part, so that the front frame is connected with the transmission box. This changes the traditional installation mode that the transmission box needs to be connected on the front frame first and then installed with the left and right guide rails. That is, the transmission box can be fixed on the left or right guide rail first, and then the front frame is slid along the left and right guide rails to the transmission box to be connected with the transmission box, so that the whole installation is more convenient. Moreover, the connecting body reduces the structure of the fixed installation of the front frame with the left and right frames, and facilitates the later disassembly and maintenance.

[0037] Specifically, in the embodiment of the present application, the connecting part 401 gradually increases in width from the lower side to the upper side by forming a guide surface. The existing general surface is only flat, but the present scheme can also achieve the convenient sliding buckling and installation of the front frame by setting one side as a guide surface and the other side as a flat surface.

[0038] Of course, in the embodiment of the application, the guide surface 42 is an inclined surface or an arc surface. It also has a guiding effect.

[0039] In the embodiment of the application, the opposite two side surfaces of the connecting part 401 are the guide surfaces 42, and the opposite two side surfaces of the connecting part 401 are provided with the buckle connecting positions 41. This is equivalent to that the two guide surfaces 42 and the two buckle connecting positions 41 are symmetrically arranged. Since the left guide rail or the right guide rail needs to be mounted with a transmission box, the symmetric arrangement of the connecting structure makes the connecting structure applicable to the mirror image arrangement of the left guide rail or the right guide rail.

[0040] In the embodiment of the application, the buckle connecting position 41 is mainly used for cooperating with the connecting arm of the front frame to be buckled. Therefore, the buckle connecting position 41 is theoretically arranged on the guide surface. Further, in the embodiment of the application, the buckle connecting position 41 is located on the upper end surface of the connecting part 401. This is equivalent to that the upper end of the buckle connecting position 41 is the outer space, which can more conveniently buckle the connecting arm, so that the structure of the present application is simpler and convenient to install and use.

[0041] In the embodiment of the application, the lower side of the connecting part 401 is further provided with a pre-guide part 402, and the width of the pre-guide part 402 is equal to the minimum width of the lower side of the connecting part 401.

[0042] In the embodiment of the application, the transmission box shell 43 is further included, and the connecting body 4 is detachably connected to the transmission box shell 43. The inside of the transmission box shell 43 is mainly used for mounting transmission parts to facilitate the transmission of the motor.

[0043] In addition, in the present application, the transmission box shell 43 is provided with a downward extending plug-in part 431. The plug-in part 431 is connected to the left guide rail or the right guide rail to form a ceiling frame.

[0044] In the embodiment of the application, the connecting part 401 can also be used for mounting and connecting with a driving motor assembly. The end surface between the two guide surfaces 42 of the connecting part 401 is provided with a positioning hole 4011 and a locking hole 4012.

[0045] As Figures 12 to 14As shown, in the embodiment of the present application, the specific structure of the front frame is that the front frame 11 comprises a connecting plate 111, a front baffle 112 arranged on the front side of the connecting plate 111, and a connecting arm 113 arranged on the rear side of the connecting plate 111, an installation cavity 101 is formed between the upper side of the connecting plate 111 and the front baffle 112 and the connecting arm 113, and a clamping edge 114 is arranged on the connecting arm 113 and extends along the length direction of the connecting arm 113 and protrudes into the installation cavity 101. The front frame of the traditional U-shaped structure is changed, the front frame can accommodate the motor assembly through the installation cavity, and is mainly installed and fixed through the structure of the connecting arm, the clamping edge on the connecting arm can better fix the front frame, for example, is buckled into the matched buckling position, and the single-sided connecting arm can be matched with the guide surface of the installation part by utilizing the deformation of the connecting arm during installation, so that the installation mode of the whole front frame is simpler.

[0046] In the embodiment of the present application, the front baffle 112 of the front frame is not only used to form the installation cavity 101, but also plays a certain shielding effect on the installation cavity 101 after installation. In order to completely shield the installation cavity 101, an additional lower baffle can be used.

[0047] Further, in the embodiment of the present application, the first length d1 of the upper side of the connecting plate 111 of the front frame 11 is less than the second length D1 of the upper side of the connecting arm 113 of the connecting plate 111. The opening of the installation cavity 101 is mainly formed downward, so that the parts in the installation cavity 101, such as the motor, can be directly disassembled during maintenance or disassembly in the use process. Compared with the traditional U-shaped structure, the assembly and disassembly are simpler and more convenient.

[0048] In the embodiment of the present application, the clamping edge 114 is arranged at the upper end of the connecting arm 113 and is bent from the upper end of the connecting arm 113 into the installation cavity 101. Specifically, the clamping edge 114 is perpendicular to the connecting arm 113. The structure is simple and easy to manufacture.

[0049] In addition, in the embodiment of the present application, the lower side of the connecting plate 111 and the front baffle 112 and the connecting arm 113 form a curtain body cavity 102. The curtain body cavity 102 is mainly used for installing the curtain body 19.

[0050] In the embodiment of the present application, the connecting plate 111 is further provided with a through hole 1111 penetrating from the lower side to the installation cavity 101. It is convenient for the anti-falling mechanism to pass through. Generally, the curtain body of the ceiling curtain uses a soft honeycomb curtain or a lily curtain. With the increase of the size of the curtain body width, the curtain body itself is easy to fall. The front frame of the present solution can be additionally provided with an anti-falling retaining mechanism to keep the curtain body in a state of not falling.

[0051] Specifically, in this embodiment of the invention, the inner surfaces of the front baffle 112 and the connecting arm 113 are respectively provided with a first protruding edge 1121 and a second protruding edge 1131. The first protruding edge 1121 and the second protruding edge 1131 are located inside the mounting cavity 101. The first protruding edge 1121 and the second protruding edge 1131 are arranged opposite to each other and both extend along the length direction of the connecting plate 111. The first protruding edge 1121 and the second protruding edge 1131 are located on the same plane parallel to the connecting plate 111 and are spaced apart from the connecting plate 111. The first protruding edge 1121 and the second protruding edge 1131 mainly create a space in the cavity that is spaced apart from the connecting plate 111. This space facilitates wiring. For example, after the motor assembly is installed, the motor housing is generally stuck in the first protruding edge 1121 and the second protruding edge 1131, and the space below it can be used to thread wires.

[0052] In this embodiment of the invention, the front baffle 112 and the connecting arm 113 are respectively provided with curtain-blocking protrusions on the inner wall of the curtain cavity 102. The curtain-blocking protrusions on both sides are spaced apart from the lower side of the connecting plate 111 to form a double curtain layer 1021, and the curtain-blocking protrusions on both sides form an opening for the curtain body to pass through. Its structure is simple and convenient for installing the curtain body 19.

[0053] like Figures 15 to 18 As shown in the embodiment of the present invention, the specific structure of the drive assembly 3 is as follows: it includes a housing 31, and a guide positioning structure 32 and a locking structure 33 are provided on one end face 302 of the housing 31. This solution changes the traditional method of fixing the housing to the front frame by screws, and directly adds a mounting and fitting structure to the housing 31 to make the overall installation and disassembly of the motor assembly more convenient.

[0054] Specifically, the guide positioning structure 32 is used to insert into the mounting part to restrict the rotation of the housing 31 relative to the mounting part 401 of the transmission box. The locking structure 33 is used to dock with the mounting part and restrict the movement of the housing 31 relative to the mounting part 401. The housing 31 is also provided with an unlocking part 34 for moving the locking structure 33 to unlock it. The housing for integrating the motor can be directly installed and fixed to the transmission box, thus changing the traditional structure where the motor needs to be fixed to the front frame. This makes motor removal more convenient during assembly and subsequent disassembly and maintenance, and even allows for motor removal and maintenance without disassembling the frame. Furthermore, the guide positioning structure further prevents the steering reaction force generated when the motor drives the curtain to move during use, which helps improve the stability after installation.

[0055] Of course, the guide positioning structure 32 should prevent the motor from rotating relative to the transmission box. It can be: the guide positioning structure 32 is a protruding column structure that protrudes outward from the end face of the housing 31, and the guide positioning structure 32 includes at least two of the protruding columns.

[0056] As the second embodiment of the guide positioning structure 32, the guide positioning structure 32 can also be only a concave position structure, and the above-mentioned effect can also be achieved by adapting a convex column structure which can be inserted into the concave position on the end surface of the mounting portion 401.

[0057] In the embodiment of the present application, in order to more effectively limit the overall rotation of the motor during operation by the guide positioning structure 32, the guide positioning structure 32 has three convex columns, and the three convex columns are distributed in a triangular manner.

[0058] In the embodiment of the present application, the specific structure of the shell 31 for the integrated drive assembly is that the shell 31 includes a left shell 311 and a right shell 312 which are butted against each other, and an inner cavity 301 is formed in the inner part of the left shell 311 and the right shell 312 after being butted against each other, and a transmission rod through hole 303 which penetrates to the inner cavity 301 is further arranged on the end surface 302. In this way, the motor can be butted against the transmission box through the transmission rod which is extended after being butted against the transmission assembly in the inner cavity 301, so as to facilitate the control of the curtain body.

[0059] Further, in the embodiment of the present application, the specific structure of the locking structure 33 is that the locking structure 33 includes a locking block 331 arranged in the inner cavity 301 and an elastic reset member arranged on the locking block 331, the locking block 331 is provided with a buckle end 3311 which is extended to the outside of the end surface 302, and the locking block 331 can move up and down in the inner cavity 301. The locking structure 33 is mainly used to limit the loosening of the shell and the transmission box after being connected, and the present scheme adopts a buckle mode, and the buckle end 3311 is directly buckled into the mounting portion 401.

[0060] Specifically, in order to make the locking effect better after buckling, the locking block 331 is provided with two buckle ends 3311 which are arranged in a vertical direction.

[0061] In the embodiment of the present application, in order to facilitate the contact locking, the locking block 331 as a whole can move relative to the shell 31, so as to make the buckle end 3311 loose. In order to facilitate the movement of the locking block 331 from the outside of the shell 31, the locking block 331 is provided with a convex block 3312 on the side surface, and the unlocking portion 34 is a hollow position which is arranged on one side of the shell 31 and opposite to the convex block 3312. The user only needs to drive the locking block 331 to move in the shell 31 through the hollow unlocking portion 34, so as to make the buckle end loose.

[0062] In the embodiment of the present application, the locking block 331 is provided with the convex block 3312 on both sides, and the shell 1 is provided with the unlocking portion 34 on both sides. This structure is convenient for the installation of the shell 31 on the left side or the right side, and no matter whether the shell 31 is installed on the transmission box of the left guide rail or the transmission box of the right guide rail, the unlocking portion 34 can be exposed on the lower side, so as to facilitate the disassembly in the later period.

[0063] like Figures 19 to 25 As shown in the embodiment of the present invention, the driving device includes a driving assembly 3, a first transmission box 4, a second transmission box 5, a left transmission assembly, a right transmission assembly, and a curtain traction clamp 191.

[0064] In this design, the left transmission assembly is mounted on the first transmission box 4, and the left transmission assembly has a left moving seat 133 connected to the curtain traction clamp 191. The right transmission assembly is mounted on the curtain traction clamp 191, and the right transmission assembly has a right moving seat 143 connected to the curtain traction clamp 191. The curtain traction clamp 191 is used to connect to the end of the curtain 19, and the curtain is opened or closed by the curtain traction clamp 191. The drive assembly can directly drive the curtain traction clamp to move through the transmission assemblies on both sides. Specifically, the drive assembly 3 is connected to the first transmission box 4 and the second transmission box 5, and is used to drive the left transmission assembly and the right transmission assembly to make the curtain traction clamp 191 drive the curtain 19 to move.

[0065] In addition, since the ceiling blind is placed horizontally during daily use and its curtain body moves on a horizontal plane, this embodiment of the invention adds a fall-prevention mechanism to prevent the curtain body from falling when it is opened or closed. This mechanism includes a fixed base 61 and a rope winding member 62 mounted on the fixed base 61 and rotatable relative to the fixed base 61. A fall-prevention rope 63 is wound around the rope winding member 62. One end of the fall-prevention rope 63 passes through the curtain body 19 and connects to the curtain body traction clamp 191. By driving the rope winding member 62 to rotate, the fall-prevention rope 63 can be wound up and down within the curtain body 19 as the curtain body 19 moves. The fall-prevention mechanism uses the fall-prevention rope to pass into the curtain body and connect to the curtain body traction clamp. When the ceiling blind's drive assembly moves the traction clamp, the rope winding member of the fall-prevention rope rotates synchronously, allowing the fall-prevention rope to automatically wind up as the curtain body moves. Its structure is simple, achieves a fall-prevention effect, and the fall-prevention rope is not exposed on the frame.

[0066] In this embodiment of the invention, the advantage of using the above structure is that the current anti-fall retaining mechanism that uses pulley blocks requires at least two sections of rope set along the direction of curtain movement, which is equivalent to releasing one end and pulling the other end to maintain the straightness effect. However, this solution only requires one section, which greatly saves space. Moreover, when used on curtains with relatively large dimensions, multiple sets can be set in parallel to ensure its anti-fall effect.

[0067] In addition, in the embodiment of the present application, in order to ensure that the anti-falling line rope is not excessively wound, the winding speed of the winding member 62 for winding the anti-falling line rope 63 is consistent with the moving speed of the curtain body 19. The difference between the present solution and the traditional solution is that the power for unwinding the anti-falling line rope 63 in the traditional solution needs to rely on the curtain body traction clamp 191, which can be understood as that the curtain body traction clamp 191 pulls one end of the anti-falling line rope 63 to make the winding member 62 rotate, while in the present solution, the winding member 62 can be rotated by a separate drive, and only the linear speed of the rotation of the winding member needs to be kept consistent with the unwinding and winding speed of the anti-falling line rope and the moving speed of the curtain body 19.

[0068] In order to make the structure simpler, in the embodiment of the present application, the drive of the winding member 62 and the drive of the curtain body movement are the same set of drive assemblies. The drive assembly is used for connection with the transmission box, and is also connected with the winding member. The specific structure is that the drive assembly 3 is connected with the second transmission box 5 through the first transmission member 39, the middle part of the winding member 62 is provided with an axial hole 6201 penetrating through both ends, the axial hole 6201 is provided with a transmission connection part 621, and the first transmission member 39 penetrates through the transmission connection part 621 to make the drive assembly 3 drive the curtain body traction clamp 191 to move while driving the winding member 62 to rotate. This ensures that the winding member winds and unwinds the anti-falling line rope 63 according to the forward and reverse rotation of the motor, and makes the winding and unwinding speed of the anti-falling line rope consistent with the unfolding and folding of the curtain body. The structure is simple and convenient to install and use.

[0069] In addition, the transmission connection part 621 is a polygonal hole, and the outer periphery of the first transmission member 39 is a polygon that matches the transmission connection part 621. The structure is simple and convenient to match and install.

[0070] In the embodiment of the present application, in order to better keep the unwinding and winding speed of the anti-falling line rope consistent with the moving speed of the curtain body 19, the left transmission assembly includes a left synchronous belt 131, a left transmission tooth 132 arranged in the first transmission box 4 and in meshing transmission with the left synchronous belt 131, the right transmission assembly includes a right synchronous belt 141, a right transmission tooth 142 arranged in the second transmission box 5 and in meshing transmission with the right synchronous belt 141, and the outer diameter of the winding member 62 is basically consistent with the outer diameter of the left transmission tooth 132 and the right transmission tooth 142. In the present solution, the outer diameter is basically consistent, which means that the outer periphery of the winding of the winding member 62, the outer periphery of the left transmission tooth 132 and the right transmission tooth 142 and the outer periphery size of the contact with the synchronous belt are the same, so as to ensure that the linear speed of the outer periphery is the same when the three rotate at the same speed, and the above-mentioned keeping the unwinding and winding speed of the anti-falling line rope consistent with the moving speed of the curtain body 19 is realized. Of course, since the winding member 62 is provided with a winding groove or a threaded groove on the surface for embedding the anti-falling line rope 63, the outer diameter basically consistent here is not the diameter of the outermost side of the winding member 62, but the diameter size of the winding groove or the threaded groove (i.e. the height of the groove wall is not calculated)

[0071] In the embodiment of the present application, the fixed seat 61 is further provided with a rope outlet 611, one end of the anti-falling rope 63 passes through the rope outlet 611 and enters the curtain body 19 and is connected with the curtain traction clamp 191, and the winding rope member 62 can move axially relative to the fixed seat 61 while rotating relative to the fixed seat 61, so that the relative position of the anti-falling rope 63 from the disengagement point to the rope outlet 611 is basically unchanged; wherein the disengagement point refers to the position where the anti-falling rope 63 is disengaged from the winding rope member 62. The winding manner of the anti-falling rope is winding along the surface of the winding rope member, which is different from the existing one in that the anti-falling rope is wound on the surface of the winding rope member in a single layer after winding, which can greatly optimize the size of the winding rope member, facilitate assembly and disassembly in a small space, and further realize the synchronous effect by keeping the position of the rope outlet basically unchanged while the winding rope member rotates and moves axially to reduce the speed error of the anti-falling rope winding and the curtain movement.

[0072] In the embodiment of the present application, the relative position of the anti-falling rope 63 from the disengagement point to the rope outlet 611 is basically unchanged to improve the synchronization of the winding speed of the anti-falling rope 63 and the movement speed of the curtain, and the basically unchanged here means that the disengagement position of the anti-falling rope 63 from the winding rope member can be limited to keep it unchanged.

[0073] Specifically, in the embodiment of the present application, the winding rope member 62 is a long cylindrical shape, and the anti-falling rope 63 is wound on the outer periphery of the winding rope member 62. The greatest advantage is that the anti-falling rope 63 is wound on the surface of the winding rope member 62 in a single layer after winding, without the need to increase the baffle on both sides to form a wire slot as in the current winding rope member, so that the outer diameter of the winding rope member 62 can be smaller, facilitating assembly and use in a small space.

[0074] In the embodiment of the present application, the axial movement of the winding rope member 62 is achieved through simple screw thread cooperation, the fixed seat 61 is provided with a mounting hole 6101 through which the winding rope member 62 passes, the outer periphery of the winding rope member 62 is provided with a screw thread extending in the axial direction, and the inner wall of the mounting hole 6101 is provided with a screw thread part cooperating with the screw thread of the outer periphery of the winding rope member 62, so that the winding rope member 62 moves axially synchronously while rotating. While the winding rope member winds and unwinds the anti-falling rope 63, the axial movement is achieved through the screw thread cooperation structure, and the direction of the axial movement can be controlled according to the different rotation directions, so that the relative position of the anti-falling rope 63 from the disengagement point to the rope outlet 611 is basically unchanged.

[0075] As optimization, in the embodiment of the present application, a spiral groove is formed on the outer periphery of the winding rope 62 by the thread, and the anti-falling rope 63 is wound along the spiral groove. Not only can it realize the axial movement of the winding rope 62 by matching with the threaded matching part, but also can serve as a groove for limiting the anti-falling rope 63, thereby keeping the position of the anti-falling rope 63 after winding, and keeping the relative position of the anti-falling rope 63 from the disengagement point to the rope outlet 611 basically unchanged, further improving the effect of anti-falling.

[0076] Specifically, after the winding rope 62 is installed, the two ends thereof extend outward from the two sides of the installation opening 6101, so the present scheme also provides two rope outlets 611 to facilitate the installation and use of the anti-falling rope 63. Since the winding rope 62 extends outward from the two sides of the installation opening 6101 after installation, and the anti-falling rope 63 can only be wound on the winding rope 62 exposed on the left side of the installation opening or on the winding rope 62 exposed on the right side of the installation opening, the present scheme provides a rope outlet 611 for threading out on each side, that is, one end of the anti-falling rope 63 is fixed on the fixing hole 6200 on the left side and the other end is threaded out from the rope outlet 611 close to the left side, or one end of the anti-falling rope 63 is fixed on the fixing hole 6200 on the right side and the other end is threaded out from the rope outlet 611 close to the right side.

[0077] In addition, in the embodiment of the present application, the bottom of the fixing seat 61 is also provided with a downwardly extending connecting protrusion 610. The connecting protrusion 610 facilitates the quick installation of the fixing seat 61.

Its structure is simple and convenient to install and use.

[0079] In the embodiment of the present application, in order to keep the anti-falling rope in a tensioned state, a tensioning assembly 64 is further included, which comprises a connecting seat 641 arranged on the curtain body traction clamp 191 and an elastic member 642 arranged on the connecting seat 641, and the end of the anti-falling rope 63 is connected to the elastic member 642. The tensioning assembly 64 is used to keep the anti-falling rope 63 in a straightened state in the curtain body 19. The tensioning assembly connected to the end of the anti-falling rope on the curtain body traction clamp can keep the anti-falling rope in a straightened and tensioned state, thereby eliminating the errors generated during the manufacture and installation of the anti-falling retaining mechanism and avoiding affecting the anti-falling effect of the curtain body. Moreover, the tensioning assembly of the present scheme has a simple structure, and the anti-falling rope can be directly connected by using the elastic effect of the elastic member.

[0080] In the embodiment of the present application, the specific structure of the tensioning assembly is that the connecting seat 641 is arranged perpendicularly to the moving direction of the curtain body, and the first lug 6411 and the second lug 6412 are arranged on the two sides of the connecting seat 641 and are bent towards the moving direction of the curtain body. One end of the anti-falling line rope 63 extends to the curtain body traction clamp 191 along the moving direction of the curtain body and is bent to one side of the connecting seat 641 and connected with the elastic member 642. That is, the anti-falling line rope 63 is arranged in an L shape. Such an arrangement mode enables the anti-falling line rope 63 to always keep a straight line segment in the same direction as the moving direction of the curtain body, and it is just the straight line segment that plays a supporting effect for preventing the curtain body from falling. In addition, the anti-falling line rope 63 can be pre-tensioned during installation, and the compensation length direction of the anti-falling line rope 63 is perpendicular to the moving direction of the curtain body, so that the straight line segment of the anti-falling line rope 63 does not affect the effect of preventing the curtain body from falling.

[0081] Specifically, in the embodiment of the present application, one end of the elastic member 642 is connected to the second lug 6412 away from the anti-falling line rope 63 and is arranged along the length direction of the connecting seat 641. The structure is simple, and the two bent first lug 6411 and second lug 6412 form a mounting and connecting structure to facilitate the assembly of the elastic member 642 and the positioning and installation of the anti-falling line rope 63.

[0082] In the embodiment of the present application, the first lug 6411 is further provided with a notch, the anti-falling line rope 63 extends in the curtain body along the moving direction of the curtain body and is bent to the connecting seat 641 from the notch of the first lug 6411 and connected with the elastic member 642. In addition, in the present scheme, the elastic member 642 is a spring. The structure is simple, and the anti-falling line rope 63 can be kept in a straight tensioning state, thereby improving the effect of preventing the curtain body from falling.
