Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtains, and in particular to a rolling curtain with adjustable gaps and which can be quickly installed without punching holes. Background Art

[0002] Roller blinds are generally equipped with an operating mechanism to control the lifting of the curtains. The operating mechanism can be divided into manual mechanical and electric types, among which the manual mechanical operating mechanism is more common. Because the operating mechanism is located on one side of the roller blind and there is an installation error when the roller blind is installed, the curtain cloth is often not located in the middle of the window, resulting in uneven gaps on the left and right, affecting the shading effect and appearance. In addition, there are generally two ways to install roller blinds: punching installation and non-punching installation. Non-punching installation is becoming more and more popular in the market because it does not damage the wall and is easy to install. Through the non-punching installation mechanism provided on the curtain track, curtains and other products are installed in window frames, door frames and other locations. The non-punching curtain products on the market are generally realized by a threaded structure, which has the problems that the thread is easy to wear after repeated use, and it is difficult for users to tighten the thread by hand, which is time-consuming and laborious. Some even need to use a wrench to install it firmly. In addition, due to the measurement error of the size of the window frame and other dimensions during the non-punching installation, the gap between the curtain cloth and the window frame is further uneven. Therefore, it is very necessary to design a roller blind product with adjustable gap and convenient non-punching installation. Utility Model Content

In order to prevent the first mounting frame 4 and the rotating head positioning shaft 58 from rotating relative to each other, the rotating head mounting hole 62 is evenly provided with cross grooves. Correspondingly, the mounting frame positioning column 73 is also provided with a cross structure, so that after the mounting frame positioning column 73 is inserted into the rotating head mounting hole 62, the two cannot rotate relative to each other, thereby preventing the first mounting frame 4 and the rotating head positioning shaft 58 from rotating relative to each other. Furthermore, a plurality of retaining ribs are distributed on the outer side of the rotating head rotating sleeve 59, and the retaining ribs cooperate with the retaining ribs provided inside the left end of the reel 5, thereby installing the rotating head rotating sleeve 59 inside the left end of the reel 5 and preventing the rotating head rotating sleeve 59 and the reel 5 from rotating relative to each other.

[0127] As for the rotational connection between the rotating head positioning shaft 58 and the rotating head rotating sleeve 59, Figure 3 As shown, an elastic buckle 61 is provided on the side of the rotating head positioning shaft 58 away from the first mounting frame 4, the rotating head rotating sleeve 59 is a hollow structure as a whole and a limiting hole 60 is formed at the tail end of the hollow structure, the rotating head positioning shaft 58 is inserted from the front end of the rotating head rotating sleeve 59, and then the elastic buckle 61 of the rotating head positioning shaft 58 passes through the hollow structure of the rotating head rotating sleeve 59 and is clamped by the limiting hole 60, thereby realizing the rotating head positioning shaft 58 and the rotating head rotating sleeve 59. Rotational connection is achieved while avoiding separation of the two.

[0128] As for the connection between the roller blind lifting mechanism 3, the second mounting frame 10 and the right end of the roller tube 5, Figure 5 As shown, the roller blind lifting mechanism 3 includes a control pull rope 65, a lifting mechanism fixed shaft 64 and a rotating wheel assembly 130. The rotating wheel assembly 130 is rotatably sleeved outside the lifting mechanism fixed shaft 64, and the control pull rope 65 is wound around the rotating wheel assembly 130. Figure 4 As shown, the overall shape of the second mounting frame 10 is the same as that of the first mounting frame 4, and a mounting frame positioning column 73 is provided on the side of the longitudinal right-angle plate facing the roller blind lifting mechanism 3. Figure 5As shown, a lifting mechanism mounting hole 67 is provided on the side of the lifting mechanism fixed shaft 64 facing the second mounting frame 10, and the second mounting frame 10 and the lifting mechanism fixed shaft 64 are installed and fixed through the mounting frame positioning column 73 and the lifting mechanism mounting hole 67. In order to prevent the second mounting frame 10 from rotating relative to the lifting mechanism fixed shaft 64, the mounting frame positioning column 73 of the second mounting frame 10 is also a cross structure as a whole, and accordingly, the lifting mechanism mounting hole 67 is evenly distributed with cross grooves, so that the second mounting frame 10 and the lifting mechanism fixed shaft 64 cannot rotate after the two are installed in coordination. Further, a groove is provided on the outer surface of the rotating wheel assembly 130, and the groove cooperates with the retaining rib provided inside the right end of the reel 5, thereby realizing the fixed installation of the rotating wheel assembly 130 and the right end of the reel 5, and the two cannot rotate relative to each other after installation, so that the rotating wheel assembly 130 can drive the reel 5 to rotate under the drive of the control pull rope 65.

[0129] As for the design of the roller blind lifting mechanism 3, specifically, Figure 5 As shown, in this embodiment, the roller blind lifting mechanism 3 includes a lifting mechanism housing 63, a fixing buckle 69 and a locking assembly 70 in addition to the lifting mechanism fixed shaft 64, the rotating wheel assembly 130 and the control rope 65 mentioned above, and the rotating wheel assembly 130 includes a lifting mechanism rotating wheel 68 and a rotating seat 66. Among them, the control rope 65 is a control rope used to control the lifting of the curtain 6. It is a circulating rope, which is wound on the rotating wheel assembly 130. The control rope 65 can drive the rotating wheel assembly 130 to rotate under the action of external force, and the rotating wheel assembly 130 further drives the roller tube 5 to rotate. The lifting mechanism fixed shaft 64 is the central axis of the rotating wheel assembly 130, which includes a cylindrical structure and a cylindrical structure arranged at the rear end of the cylindrical structure (i.e. Figure 5The lifting mechanism mounting hole 67 is formed on the right end of the lifting mechanism, and the lifting mechanism fixed shaft 64 is fixedly mounted on the second mounting frame 10 through the cooperation of the lifting mechanism mounting hole 67 and the mounting frame positioning column 73. The lifting mechanism rotating wheel 68 is a driving wheel driven by the control rope 67 to rotate around the lifting mechanism fixed shaft 64, which includes a hollow cylinder and a rope winding wheel 71 arranged at the rear end of the hollow cylinder (i.e., the right end in the figure). The rope winding wheel 71 is evenly distributed with a number of latch teeth, which are used to allow the control rope 67 to be wound thereon and prevent the control rope 67 from slipping relative to the lifting mechanism rotating wheel 68. The hollow structure of the hollow cylinder of the lifting mechanism rotating wheel 68 forms a positioning hole, which is used to cooperate with the cylinder of the lifting mechanism fixed shaft 64 for installation. The rotating seat 66 also includes a hollow cylinder, and it is sleeved on the outer circumference of the hollow cylinder of the lifting mechanism wheel 68 through the hollow cylinder. The front end of the lifting mechanism fixed shaft 64 (that is, the cylinder of the lifting mechanism fixed shaft 64) passes through the hollow cylinder of the lifting mechanism wheel 68 and then passes through the hollow cylinder of the rotating seat 66. The diameter of the fixing buckle 69 is larger than the inner cylinder diameter of the hollow cylinder of the rotating seat 66. It is installed on the front end of the lifting mechanism fixed shaft 64. On the one hand, it enables the rotating seat 66 and the lifting mechanism wheel 68 to rotate compared with the lifting mechanism fixed shaft 64. On the other hand, it fixes the positions of the rotating seat 66, the lifting mechanism wheel 68 and the lifting mechanism fixed shaft 64, thereby preventing these components from separating.

[0130] like Fig.25 As shown, the locking assembly 70 includes a torsion spring, which realizes locking by utilizing the characteristic that the inner diameter of the torsion spring changes when the torsion spring rotates in different directions. Specifically, the torsion spring is sleeved on the cylinder of the lifting mechanism fixed shaft 64, and a slot is provided on the hollow cylinder of the lifting mechanism rotating wheel 68, and a boss is correspondingly provided in the hollow cylinder of the rotating seat 66. When the lifting mechanism rotating wheel 68 rotates, the slot cooperates with the torsion spring torsion arm, which is located on the outside of the torsion spring torsion arm, and the lifting mechanism rotating wheel 68 drives the torsion spring to increase its inner diameter, and the torsion spring relaxes to make the lifting mechanism rotating wheel 68 rotate relative to the lifting mechanism fixed shaft 64; when the rotating seat 66 rotates, the boss cooperates with the torsion spring torsion arm, which is located on the inside of the torsion spring torsion arm, and when rotating, it drives the torsion spring to reduce its inner diameter, thereby locking relative to the lifting mechanism fixed shaft 64, thereby preventing the rotating seat 66 that cooperates with the roller tube 5 from rotating freely, so that the curtain is locked in the required position.

[0131] In addition, a groove is provided on the outer side of the rotating seat 66, and the groove cooperates with the retaining rib provided inside the right end of the winding tube 5, so that after the rotating seat 66 is connected to the winding tube 5 through the cooperation of the groove and the retaining rib, the two cannot rotate relative to each other, so that the rotating seat 66 can drive the winding tube 5 to rotate. The lifting mechanism housing 63 covers the outer side of the lifting mechanism rotating wheel 68 to prevent the control pull rope 65 from separating from and falling off the lifting mechanism rotating wheel 68. A housing positioning hole is also provided on one side of the lifting mechanism housing 63, and the housing positioning hole allows one end of the lifting mechanism fixed shaft 64 to pass through, and a rope threading hole is provided below the lifting mechanism housing 63, and the control pull rope 65 can pass through it.

[0132] The above is about the specific structural design of the rolling curtain mechanism 140 contained in the rolling curtain 500 of this embodiment. The specific design of the fixing mechanism 200 contained in the rolling curtain 500 will be further explained below.

[0133] like Figure 1 and Figure 2 As shown, the fixing mechanism 200 as a whole includes a punch-free installation mechanism 2, a support rail 1 and an end cover assembly 8. The punch-free installation mechanism 2 and the end cover assembly 8 are closely attached to the supporting wall surface, and the support rail 1 is supported and installed between the punch-free installation mechanism 2 and the end cover assembly 8. As for the support rail 1, Figure 6 As shown, the support track 1 includes a track slot 12 disposed at the lower end, and the track slot 12 is used to be slidably connected with the slide plate 72 included in the first mounting frame 4 and the second mounting frame 10 of the aforementioned rolling shutter mechanism 140, so that the rolling shutter mechanism 140 can slide horizontally relative to the support track 1. In order to prevent the rolling shutter mechanism 140 from sliding freely relative to the support track 1 due to non-artificial forces (such as the effect of wind), the cooperation between the slide plate 72 and the track slot 12 is designed in this embodiment. Since the track chute 12 is usually made of aluminum, PVC or metal, and has a thin wall thickness and a certain deformation force, in this case, the width of the slide plate 72 is slightly larger than the opening width of the track chute 12 (for example, 0 to 0.1 mm), so that after the slide plate 72 is installed in the track chute 12, the two form an interference fit relationship, so that the slide plate 72 has a certain resistance relative to the track chute 12, and the resistance is greater than the usual wind force, thereby preventing the rolling shutter mechanism 140 from sliding freely relative to the support track 1 under non-human control. The left end of the support track 1 is provided with an opening 11, which is used to cooperate with the punch-free installation mechanism 2; the lower end of the support track 1 extends toward the rolling shutter mechanism 140 to form a light blocking plate 13, which is used to block the gap between the support track 1 and the roller tube 5, so that the rolling shutter 500 provided in this embodiment is more beautiful during use. In addition, in order to enhance the strength of the support rail 1 , the present embodiment provides a rail reinforcing rib 14 on the support rail 1 to increase the strength of the support rail 1 and reduce the probability of deformation of the support rail 1 .

[0134] As for the design of the end cap assembly 8, Fig.16 As shown, the end cap assembly 8 is installed at the right end of the support track 1, and it fits with the support wall. The end cap assembly 8 includes an end cap 54 and an anti-skid component 20. The end cap 54 is provided with a mounting boss 57, and the shape of the mounting boss 57 corresponds to the shape of the inner side of the right end of the support track 1. The end cap 54 is inserted into the inner side of the right end of the support track 1 through the mounting boss 57. An end cap groove 55 is provided at one end of the end cap 54 facing the support wall, and the anti-skid component 20 is installed in the end cap groove 55, so as to contact with the support wall to prevent the rolling curtain mechanism 140 from sliding relative to the support wall after the punch-free installation. In addition, an end cap slide groove 56 is provided at the lower end of the end cap 54, and the end cap slide groove 56 is used to position and install the slide plate 72 of the second mounting frame 10, so that when adjusting the gap of the curtain 6, the slide plate 72 of the second mounting frame 10 can slide relative to the end cap assembly 8 without hindrance.

[0135] As for the design of the punch-free installation mechanism 2, Figure 7 and Figure 8 As shown, the punch-free installation mechanism 2 generally includes an anti-slip component 20, a pre-tightening component 25, a support component 150, a pressure component 160 and a button component 170, wherein the support component 150 includes a first support member 151 and a second support member 152 that can slide relative to each other, and the first support member 151 faces one side of the supporting wall (i.e. Figure 8 The anti-skid component 20 is provided on the left side of the support rail 1. The anti-skid component 20 is used for contacting with the supporting wall surface during punch-free installation to prevent skidding. The second support member 152 faces one side of the support rail 1 (i.e. Figure 8 The pressure assembly 160 includes a first pressure member 161 and a second pressure member 162. The first pressure member 161 is installed and matched with the first support member 151, and the second pressure member 162 is installed and matched with the second support member 152. The pre-tightening assembly 25 is arranged between the first pressure member 161 and the second support member 152 to provide a pre-tightening force during the punch-free installation. The button assembly 170 is installed on the side of the second support member 152 facing the user and connected to the second pressure member 162. When the button assembly 170 is closed, the second pressure member 161 applies a pressing force toward the supporting wall to the first pressure member 161 and the first support member 151 installed and matched with the first pressure member 161 under the push of the button assembly 170.

[0136] Specifically, if Figure 8 As shown, the first support member 151 includes a support seat 21, combined with Fig.12As shown, an anti-slip groove 40 is provided on the side of the support seat 21 facing the wall support surface, and the anti-slip component 20 is installed in the anti-slip groove 40. When the roller shutter 500 provided in this embodiment is installed, the anti-slip component 20 contacts the supporting wall surface to prevent the roller shutter 500 and the supporting wall surface from sliding relative to each other. The anti-slip component 20 is preferably a silicone pad.

[0137] like Figure 7 and Figure 8 As shown, the second support member 152 includes a base 16, which is the shell of the punch-free installation mechanism 2 and is installed at the left end of the support rail 1. Fig.12 As shown, a support seat sliding rib 41 extends from the side of the support seat 21 facing away from the supporting wall, and the support seat sliding rib 41 contacts the inner wall of the base 16. The support seat 21 and the base 16 can slide back and forth relative to each other through the support seat sliding rib 41. Fig. 9 As shown, a base slot 29 is provided at the corresponding position of the base 16, and the support seat buckle 43 and the base slot 29 are installed in coordination, and the two play a limiting role, which can prevent the support seat 21 and the base 16 from separating due to excessive sliding distance.

[0138] like Figure 8 As shown, the first pressure member 161 includes a tilting block 22, which is integrally mounted in the support seat 21. Fig.13 As shown, the two sides of the inclined top block 22 are provided with second trapezoidal bosses 46, correspondingly, combined with Fig.12 As shown, two first trapezoidal bosses 42 are arranged in the support seat 21, and the second trapezoidal boss 46 of the inclined top block 22 contacts the first trapezoidal boss 42 of the support seat 21 through an inclined surface. When the inclined top block 22 is subjected to pressure toward the supporting wall, the second trapezoidal boss 46 of the inclined top block 22 moves toward the supporting wall with the help of the first trapezoidal boss 42 of the support seat 21, and an inclined surface force is generated between the second trapezoidal boss 46 and the first trapezoidal boss 42, thereby pressing the support seat 21 toward the supporting wall. In order to strengthen the strength of the inclined top block 22, as shown in FIG. Fig.13 As shown, a tilted lift block reinforcement rib 48 is provided on the tilted lift block 22 .

[0139] Furthermore, combined with Fig. 9 and Fig.13 As shown, the inclined lift block 22 is provided with an inclined lift block positioning shaft 47, the base 16 is provided with a positioning cylinder 31, and the two ends of the pre-tightening component 25 are respectively positioned and installed on the positioning shaft 47 and the positioning cylinder 31. The pre-tightening component 25 is a cylindrical spring, which provides a pre-tightening force to prompt the inclined lift block 22 to press the support seat 21 toward the supporting wall.

[0140] like Figure 8 As shown, the second pressure member 162 includes a rectangular top block 24, combined with Fig.15As shown, the top block 24 is provided with a motion slide 51, corresponding to which, combined with Fig. 9 As shown, the base 16 is provided with a rectangular hole 26 for mounting the rectangular top block 24 , and a plurality of base limiting ribs 27 are distributed on the inner circumference of the rectangular hole 26 . The rectangular top block 24 and the base 16 are slidably connected through the cooperation of the motion slide groove 51 and the base limiting ribs 27 .

[0141] Combination Figure 8 , Fig.13 , Fig.15 As shown, a rectangular top block serration 53 is provided on the inner side of the rectangular top block 24, and a slanted top block serration 45 is provided on the outer side of the inclined top block 22. One side of the support seat 21 has an opening, thereby allowing the slanted top block serration 45 of the inclined top block 22 to be exposed to the outside. When the slanted top block serration 45 is engaged with the rectangular top block serration 53, relative displacement cannot occur between the inclined top block 22 and the rectangular top block 24.

[0142] like Figure 7 and Figure 8 As shown, the button assembly 170 as a whole includes a button bracket 18, a button 17, a connecting rod 23 and a button installation shaft 19. The button bracket 18 is installed at the front opening of the base 16 (Note: the so-called front refers to the side facing the operator when the support-free installation is performed). The button 17 is a component for controlling the quick tightening installation of the punch-free installation mechanism 2. It is rotatably connected to the button bracket 18 through the button installation shaft 19. The connecting rod 23 is rotatably connected to the button 17 and is slidably connected to the moment top block 24. When the button 17 is closed for punch-free installation, the button 17 is pressed. The button 17 rotates around the button mounting shaft 19 relative to the button bracket 18, and the button 17 and the connecting rod 23 driven by the button 17 push the moment top block 24 inwardly. The moment top block 24 slides toward the inside of the base 16 with the cooperation of the motion slide groove 51 and the base limiting rib 27. Due to the sawtooth meshing of the moment top block 24 and the inclined top block 22, the two cannot slide relative to each other. The moment top block 24 will transfer the pressure it receives to the inclined top block 22, thereby causing the inclined top block 22 to receive pressure toward the supporting wall surface, so the inclined top block 22 presses the support seat 21 toward the supporting wall surface. When the button 17 is opened to release the punch-free installation, the button 17 drives the moment top block 24 to move outward, so that the moment top block 24 and the inclined top block 22 are separated, and the two can move relative to each other.

[0143] Specifically, if Fig. 9 As shown, the outer edge of the rectangular hole 26 of the base 16 is provided with a button bracket mounting groove 30, combined with Fig.11As shown, the button bracket 18 is provided with a button bracket mounting rib 39, and the button bracket mounting rib 39 of the button bracket 18 is installed in cooperation with the button bracket mounting groove 30 of the base 16, thereby preventing the button bracket 18 and the base 16 from sliding relative to each other. In addition, button bracket clamping grooves 38 are provided on both sides of the button bracket 18, and base buckles 28 are provided at corresponding positions of the base 16. The button bracket clamping grooves 38 of the button bracket 18 are installed in cooperation with the base buckles 28 of the base 16, thereby preventing the button bracket 18 and the base 16 from separating after installation. The button bracket 18 is also provided with two shaft holes 37, which are combined with the base buckles 28 of the base 16. Fig.10 As shown, a button mounting hole 35 is also provided at the corresponding position of the button 17, and the button mounting shaft passes through the shaft hole 37 and the button mounting hole 35, thereby connecting the button 17 with the button bracket 18, and the button 17 can be rotated relative to the button bracket 18 through the button mounting shaft, and the button mounting shaft can be a metal rivet. Fig.10 As shown, the rotating end of the button 17 is provided with a cam 36, and the cam 36 is deflected at a certain angle with the axis of the button mounting shaft. The free end of the button 17 is the button body 33, and the user can apply pressure or tension to the button 17 through the button body 33, thereby driving the cam 36 to rotate. When the punch-free support is used, the button 17 is pressed, and the cam 36 can prevent the button 17 from rotating, and the cam 36 will contact the moment top block 24 when rotating, thereby pushing the moment top block 24 to move.

[0144] like Fig.14 As shown, the connecting rod 23 is a component connecting the button 17 and the moment top block 24, and a first mounting shaft 49 is provided at one end thereof, and a second mounting shaft 50 is provided at the other end thereof. Fig.10 As shown, the button 17 is provided with a connecting rod mounting hole, and the connecting rod 23 is installed with the button 17 through the installation cooperation between the first installation shaft 49 and the connecting rod mounting hole; at the same time, as shown Fig.15 As shown, sliding grooves 52 are provided on both sides of the moment top block 24, and the second mounting shaft 50 of the connecting rod 23 is installed in the sliding grooves 52, so that the connecting rod 23 is connected to the moment top block 24 and the connecting rod 23 can slide relative to the moment top block 24. When the button 17 is opened, the punch-free support is released, and the connecting rod 23 moves under the drive of the button 17, thereby driving the moment top block 24 to move outward, thereby releasing the pressure of the moment top block 24 on the inclined top block 22. When the button 17 is closed for punch-free support, the button 17 drives the connecting rod 23 to cause the moment top block 24 to move inward, and the moment top block 24 causes the inclined top block 22 to press the support seat 21 toward the supporting wall surface.

[0145] Furthermore, if Fig. 9 As shown, the lower end of the base 16 is also provided with a base slide groove 32, which is an extension of the track slide groove 12 for the slide plate 72 of the first mounting frame 4 to slide therein. Fig.12As shown, a notch 44 is further provided on the outer side of one end of the support seat 21 , and the notch 44 allows the first mounting bracket 4 to pass through the support seat 21 when sliding.

[0146] Second Embodiment

[0147] like Figures 17 to 23 The present embodiment provides a roller blind 500 with adjustable gap and quick installation without punching. The main difference between the roller blind 500 and the roller blind provided in the first embodiment is the different operating device for controlling the lifting of the roller blind. In the first embodiment, the main body of the roller blind lifting mechanism 3 for controlling the lifting of the roller blind is the control pull rope 65 and the rotating wheel assembly 130 driven by the control pull rope 65. The roller blind lifting operating device provided in the present embodiment has a main body of a tension-free spring system 77 and a locking rotary head 76. Compared with the first embodiment, the present embodiment does not require a pull rope control. When operating, it is only necessary to pull the curtain 6 to the corresponding position for locking. When the curtain 6 is retracted, the curtain 6 is pulled down again to unlock it and then the curtain 6 is automatically rebounded by the spring to rise. Since the basic frame structure of the quick punch-free installation roller shutter 500 with adjustable gap provided in this embodiment is the same as that of the first embodiment, the same contents will not be described in detail in this embodiment. The following describes the different designs of this embodiment compared with the first embodiment (mainly the tension-free spring system 77 and the locking rotary head 76, and the first mounting frame 75 slightly adjusted to accommodate the tension-free spring system 77).

[0148] like Fig.17 and Fig.18 As shown, the roller blind lifting mechanism 500 provided in this embodiment includes a tension-free spring system 77 and a locking swivel 76. Overall, the tension-free spring system 77 is installed on the left side of the roller tube 5, and the locking swivel 76 is installed on the right end of the roller tube 5. The tension-free spring system 77 is installed in conjunction with the first mounting frame 75, and drives the roller tube 5 to rotate through the spring torque to retract or lower the curtain 6. The locking swivel 76 is installed in conjunction with the second mounting frame 10, and is used to lock or unlock the roller tube 5 during its rotation.

[0149] As for the design of locking the rotor 76, Fig. 20 As shown, it includes a locking sleeve 79, a locking fixed shaft 80, a clamp 82 and a trackball 85. The locking sleeve 79 is sleeved and installed on the outside of the locking fixed shaft 80, and the locking sleeve 79 can rotate relative to the locking fixed shaft 80. The locking sleeve 79 is fixedly installed with the end of the reel 5, and the locking fixed shaft 80 is fixedly installed with the second mounting frame 10, so that the reel 5 can be rotated by rotating the locking sleeve 79 relative to the locking fixed shaft 80. Specifically:

[0150] The locking fixed shaft 80 is located at the center of the locking rotating sleeve 79, and one end of the locking fixed shaft 80 extends out of the locking rotating sleeve 79. The extended end is designed with a locking slot 83, and the locking slot 83 is installed in cooperation with a clamp 82. The size of the clamp 82 is larger than the size of the opening of the locking rotating sleeve 79 for the locking fixed shaft 80 to pass through. The design of the clamp 82 allows the locking rotating sleeve 79 and the locking fixed shaft 80 to be assembled together without hindering the locking rotating sleeve 79 from rotating around the locking fixed shaft 80. A plurality of retaining ribs are distributed on the outer side of the locking rotating sleeve 79, and the retaining ribs cooperate with the retaining ribs on the inner side of the end of the winding tube 5 to achieve the fixed installation of the locking rotating sleeve 79 and the winding tube 5, thereby preventing the relative movement of the locking rotating sleeve 79 and the winding tube 5. Furthermore, a cross-shaped positioning mounting hole is provided on the side of the locking and fixing shaft 80 facing the second mounting frame 10, and a mounting frame positioning column 73 is provided on the side of the second mounting frame 10 facing the locking and fixing shaft 80. The locking and fixing shaft 80 and the second mounting frame 10 are installed and fixed through the cooperation of the positioning mounting hole and the mounting frame positioning column 73, and the two cannot rotate relative to each other.

[0151] Further, as to how the locking rotor 76 can be automatically locked, Fig. 20 As shown, the outer surface of the locking fixed shaft 80 is provided with a track groove 84, the cross section of the track groove 84 is semicircular, and the track ball 85 moves along the track groove 84; and the corresponding position of the inner hole wall of the locking rotating sleeve 79 is provided with a semicircular groove hole 81, and the semicircular groove hole 81 allows the track ball 85 to move thereon. When the curtain 6 is pulled down, the rolling tube 5 rotates and causes the locking rotating sleeve 79 to move around the locking fixed shaft 80, and the track ball 85 is in the semicircular groove hole 81 of the locking rotating sleeve 79, and moves along the track groove 84 of the locking fixed shaft 80 under the action of the locking rotating sleeve 79. When the curtain 6 stops being pulled, the rolling tube 5 rotates under the action of the tension-free spring system 77, and the track ball 85 rotates along the track groove 84 driven by the locking rotating sleeve 79, and will fall on the limiting concave hole of the track groove 84, thereby locking. Pulling down the curtain 6 again can release the lock.

[0152] As for the design of the tension-free spring system 77, Fig.21As shown, the tension-free spring system 77 includes a rotating head 86, a fixed rod 87, a spring 89, a damper 90, a one-way rotating wheel 91 and a screw 92. The spring 89 is sleeved on the fixed rod 87, the left end of the fixed rod 87 is fixedly mounted on the first mounting bracket 75, the right end of the fixed rod 87 is fixedly mounted on the damper 90, the rotating head 86 is installed on the inner side of the roller tube 5 and sleeved on the left end of the fixed rod 87, and the rotating head 86 can rotate around the left end of the fixed rod 87 driven by the roller tube 5. The spring 89 is a spiral spring, and its two ends are respectively fixed on the rotating head 86 and the damper 90. The damper 90 is assembled with the one-way rotating wheel 91. When the curtain 6 is lowered, the one-way rotating wheel 91 rotates with the roller tube 5 and drives the damper 90 to move to provide damping. When the curtain is raised, the one-way rotating wheel 91 rotates freely with the roller tube 5, but the damper 90 does not rotate. This makes it possible that when the roller tube 5 rotates around the axis in the direction of the curtain 6 descending, the left end of the spring 89 rotates with the rotating head 86 and the roller tube 5, so that the torsion of the spring 89 increases; in this process, the damper 90 moves under the drive of the one-way rotating wheel 91 to provide damping, thereby preventing the curtain 6 from being pulled too fast due to excessive tension. When the roller tube 5 rotates around the axis in the direction of the curtain 6 ascending, the torsion of the spring 89 is released, thereby driving the roller tube 5 to rotate, and in this process, the one-way rotating wheel 91 rotates freely with the roller tube 5, but the damper 90 does not move.

[0153] Specifically:
