[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0063] Please refer to the above as well. Figures 1 to 26 This invention provides a simple-to-install curtain. The curtain features adjustable gaps, no drilling required, and convenient installation. It includes a support track 1, a mounting frame 5, a drive unit 4, and a curtain assembly. The support track 1 is connected to a supporting wall. The mounting frame 5 includes a bracket 51 connected to the support track 1 and an elastic connection structure connected to the bracket 51. The drive unit 4 is rotatably connected to the elastic connection structure. The curtain assembly is connected to the drive unit 4. The drive unit 4 rotates relative to the elastic connection structure, synchronously driving the roller blind assembly to rotate. By changing the specific connection posture between the bracket 51 and the support track 1, the relative position of the drive unit 4 and the roller blind assembly relative to the support track 1 is adjusted; that is, by adjusting the connection posture between the bracket 51 and the support track 1, the position of the roller blind assembly relative to the support track is controlled.

[0064] As one specific implementation of this utility model, please refer to the following: Figures 1 to 26 The drive unit 4 is a mechanism for controlling the movement of the curtain assembly. Both ends of the drive unit 4 are fitted with mounting brackets 5 and mounted below the support rail 1 via the mounting brackets 5. Specifically, one end of the curtain assembly is fixed to the drive unit 4, and the release and retraction of the curtain assembly are controlled by the rotation of the drive unit 4. More specifically, the drive unit 4 includes a roller tube 41, a drive assembly 42, and a damping assembly 43. The roller tube 41 is located below the support rail and is connected to one end of the curtain assembly; the drive assembly 42 is located at one end of the roller tube 41 and can drive the roller tube 41 to rotate. The drive assembly 42 is a tension-free spring, which is prior art and not the focus of this case, so it will not be described in detail. The damping assembly 43 is installed at the other end of the roller tube 41 opposite the drive assembly 42 and is used to prevent the roller tube 41 from moving too fast during the curtain's ascent.

[0065] In some feasible embodiments, the roller tube 41 is located below the support rail 1, and its two ends are respectively equipped with a drive assembly 42 and a damping assembly 43 for winding up the curtain fabric assembly.

[0066] In some feasible embodiments, the drive assembly 42 is mounted at either end of the roller tube 41 to drive the roller tube 41 to rotate, thereby controlling the raising and lowering of the curtain assembly. The drive assembly 42 can be fixedly mounted to the mounting bracket 5, so that the drive unit 4 is mounted on the mounting bracket 5. The drive assembly 42 is a tension-free spring. When the curtain 6 of the curtain assembly descends, the roller tube 41 rotates and releases the curtain, increasing the spring force of the drive assembly 42. Correspondingly, when the curtain 6 rises, the spring force of the drive assembly 42 is released. It should be noted that the drive assembly 42 includes: a rotating head, a fixing rod, a spring, a damper, a one-way roller, and a screw. The drive assembly 42 is prior art and not the focus of this case; for the sake of brevity, it will not be described in detail.

[0067] In some feasible embodiments, the damping component 43 is installed at the other end of the winding tube 41 opposite to the drive component 42. As the curtain 6 rises, the winding tube 41 rotates to wind up the curtain 6. To prevent the winding tube from rotating too fast, the damping component 43 can gradually increase the rotational resistance of the winding tube, thereby achieving deceleration.

[0068] In any feasible embodiment, the damping assembly 43 includes a mounting base 431, a turntable 432, a rotating wheel 433, a rotating shaft 434, and a compression spring 435. The mounting base 431 is mounted on one end of the winding tube 41 and is cylindrical in shape. One end of the mounting base 431 has a second mounting hole 4311 for connecting the mounting damper device end of the drive unit 4 to the mounting bracket 5, and one end of the rotating shaft 434 is placed therein. The other end of the mounting base 431 has a circular hole 4313 through which the other end of the rotating shaft 434 can pass. The mounting base 431 and the rotating shaft 434 can rotate relative to each other. The outer ring of the mounting base is evenly distributed with first limiting grooves 4312, which can cooperate with the retaining ribs in the winding tube 41 to prevent the mounting base 431 from rotating relative to the winding tube 41. The turntable 432 is sleeved on the rotating shaft 434, and one end of it abuts against the circular hole end of the mounting base. The turntable 432 has a shaft hole 4321 through which the rotating shaft 434 can pass, and several retaining ribs 4322 are provided on the inner wall of the shaft hole to cooperate with the rotating shaft and prevent the turntable from rotating relative to the rotating shaft. The other end of the turntable 432 has a circular hole 4323, which is fitted with one end of a compression spring 435, and the spring force holds the turntable 432 against the mounting base 431. The rotating wheel 433 has a first threaded hole 4331 in the middle, which cooperates with the threaded rod on the rotating shaft 434, allowing the rotating wheel 433 to rotate relative to the rotating shaft 434 around its axis. One side of the rotating wheel 433 abuts against the compression spring 434. The outer ring of the rotating wheel 433 has several second limiting grooves 4332. The rotating wheel 433 is installed inside the winding tube 41 along with the damping assembly 43. The second limiting grooves 4332 are positioned and installed with the retaining ribs on the winding tube 41, so that the rotating wheel 43 and the winding tube 41 can rotate synchronously. The front end of the rotating shaft 434 has a boss 4341 located within the mounting hole of the mounting base, and the boss 4341 cannot pass through the circular hole 4313 on the mounting base. A positioning hole 4342 is provided at the center of the boss's end face. When the damping assembly 43 is installed with the mounting bracket 5, the positioning hole 4342 engages with the fixed shaft on the mounting bracket 5, preventing the rotating shaft from rotating around its axis. The positioning hole is a polygonal hole. The rear end of the rotating shaft 434 is a threaded rod 4344, which is connected to the rotating wheel 433 via a threaded connection. Several grooves 4343 are provided at the connection point between the boss 4341 and the threaded rod 4344. The turntable shaft hole 4321 passes through the threaded rod and is fitted onto it, with a retaining rib on the shaft hole engaging with the grooves to prevent the turntable from rotating relative to the rotating shaft. A limit buckle 4345 is provided at the top of the threaded rod to prevent separation after the rotating wheel is installed on the threaded rod. A compression spring 435 is installed between the turntable 432 and the rotating wheel 433 and fitted onto the threaded rod. One end of the compression spring 435 abuts against the turntable 432 and the other end abuts against the rotating wheel 433. When the rotating wheel 433 rotates along the threaded rod, the distance between the rotating wheel 433 and the turntable 432 changes, causing the compression spring 435 to contract or release, and the elastic force to change, thereby changing the friction between the turntable 432 and the mounting base 431.

[0069] As one specific implementation of this utility model, please refer to the following: Figures 1 to 26 The support track 1 is connected to the supporting wall via a no-drill assembly 2. Two sets of no-drill assemblies 2 are provided, each installed at one end of the support track 1. The no-drill assemblies 2 are used to fit against the supporting wall. This device enables quick curtain installation. The no-drill assembly 2 includes a base 21, a drive rod 22, a drive wheel 23, a support block 24, an anti-slip component 25, and an elastic element 26. The base 21 is connected to one end of the support track 1; the drive rod 22 has external threads and can slide relative to the base 21 along the extension direction of the support track 1, providing support during no-drill installation; the drive wheel 23 is threadedly connected to the drive rod 22, driving the drive rod to move. The support block 24 is installed at the front end of the drive rod 22 and can extend and retract relative to the drive rod 22. The anti-slip component 25 is installed at the front end of the support block 24 and is used to abut against the supporting wall. The elastic element 26 is a cylindrical spring located between the support block 24 and the drive rod 22.

[0070] In some feasible embodiments, the base 21 serves as a mounting base for the drill-free assembly 2, and is mounted on one end of the support rail 1. The shape of the base 21 is determined by the shape of the rail, and it has a through hole 211 arranged along the extension direction of the support rail 1. The through hole 211 is polygonal, allowing the drive rod 22 to be mounted so that the drive rod 22 can move axially relative to the base 21 along the through hole. The base 21 has several grooves 212, which engage with the snaps 222 on the drive rod 22 to prevent the drive rod 22 from separating from the base 21 after installation. The outer ring of the base 21 has mounting ribs 213, which abut against the inner wall of the rail when the base is installed on the rail.

[0071] In some feasible embodiments, the drive rod 22 is a cylindrical component mounted on the base 21, which engages with the through hole 211 on the base 21, allowing it to slide axially relative to the base 21 but not rotate relative to it. The outer surface of the drive rod 22 has an external thread 221, which engages with the internal thread 231 on the drive wheel 23. A snap fastener 222 is provided on the outer rear end of the drive rod 22, engaging with a groove 212 on the base, allowing the drive rod to be disengaged after installation on the base. The front end of the drive rod has a mounting hole 223 for mounting a support block 24. The mounting hole 223 is polygonal in shape, and the support block, after installation with the drive rod, can only move axially relative to it and cannot rotate. A baffle 224 is provided on the outer diameter of the front end of the drive rod 22, with the outer dimension of the baffle 224 larger than the through hole 211 on the base, preventing the front end of the drive rod from passing through the through hole in the base. The drive rod 22 has a bottom surface 225 inside the cylinder, and a limit hole 226 is provided on the bottom surface. When the support block 24 is installed in conjunction with the drive rod 22, one end of the support block passes through the limit hole 226.

[0072] In some feasible embodiments, the drive wheel 23 is located between the base 21 and the drive rod 22, and is threadedly mounted to the drive rod. Rotation of the drive wheel drives the drive rod to move relative to the base, thereby enabling the drill-free assembly to provide support to the wall surface. The drive wheel 23 has an internal threaded hole 231 that engages with the external thread 221 on the drive rod. The drive wheel is hexagonal for easy tightening with tools such as wrenches.

[0073] In some feasible embodiments, the support block 24 is mounted on the drive rod 22 and abuts against the support wall. The front end of the support block 24 has a receiving cavity 241 for mounting the anti-slip component 25. The rear end of the support block is a long rod 242, which is installed within the drive rod mounting hole 223, allowing the support block to move axially relative to the drive rod. Near the receiving cavity, the end of the long rod 242 has a polygonal boss 244, which engages with the drive rod mounting hole to prevent relative rotation. The other end of the long rod 242 has a latch 243, which, through a limiting hole 226 on the drive rod, restricts the separation of the support block from the drive rod.

[0074] In some feasible embodiments, the anti-slip component 25 is installed within the front receiving cavity 241 of the support block. During installation of the support rail 1, the anti-slip component 25 contacts the support wall surface to prevent the support rail 1 from sliding relative to the contact surface. In any feasible embodiment, the anti-slip component 25 is a silicone pad.

[0075] In some feasible embodiments, the elastic element 26 is sleeved on the rear end of the long rod 242 of the support block 24, with one end abutting against the polygonal end face of the long rod 244 and the other end abutting against the inner bottom surface 225 of the cylindrical drive rod 22. This generates an elastic force between the support block 24 and the drive rod 22, which can generate a preload relative to the supporting wall. In any feasible embodiment, the elastic element 26 is a cylindrical spring.

[0076] Example 1

[0077] As one specific implementation of this utility model, please refer to the following: Figures 1 to 26 The support 51 is generally L-shaped and includes a horizontal top portion and a vertical side portion.

Specifically, the bending portion is a stepped plate structure. One end of the plate structure is connected to the horizontal top portion. The other end of the plate structure is connected to the vertical side portion. The horizontal top portion is movably connected to the support rail 1.

[0078] A plate-like body 511 is provided on each side of the horizontal top surface. The bottom of the support rail 1 is provided with a sliding groove that fits the plate-like body 511. The plate-like body 511 can slide into the sliding groove at the bottom of the support rail 1, so that the bracket 51 can only move relative to the support rail 1 along the extension direction of the support rail 1.

[0079] A first positioning structure 513 for locking the position of the bracket 5 relative to the support rail 1 is provided on the transverse top surface. In any feasible embodiment, the first positioning structure 513 is a positioning hole. Several positioning holes can be selectively provided on the transverse top surface. The relative position of the bracket 5 can be fixed from inside the support rail 1 by means of fixing bolts, rivets, etc., which engage with the positioning holes. In another feasible embodiment, the first positioning structure 513 is a bolt, which is connected to the support rail 1, such that the bolt rests on the transverse top surface.

[0080] Several first reinforcing ribs 512 and second reinforcing ribs 516 are provided in the transition from the top surface to the side of the bracket 1. This ensures the stability of the bracket 1. The first reinforcing ribs 512 and second reinforcing ribs 516 are arranged along the L-shaped bend.

[0081] A second positioning structure 514 is provided on the vertical side of the bracket 51. The second positioning structure 514 is adapted to the adjusting seat 54.

[0082] The vertical side of the bracket 51 is provided with a plurality of first rivet holes 515. The outer shell 52 is fixed to the bracket 51 by rivets 56.

[0083] In some feasible embodiments, the housing 52 is generally shaped like a round cap, and includes a cap head 521, a positioning hole 522, and a countersunk hole 524. The cap head 521 is used for positioning and mounting with the drive unit 4. The positioning hole 522 is used to fix one end of the shaft 53 through it. The countersunk hole 54 is used to fit its inner wall against the outer diameter of the torsion spring 55.

[0084] In any feasible embodiment, the housing 52 further includes a second rivet hole 523 for securing the housing 52 to the bracket 51 by means of rivets.
