Description

Technical Field

[0001] This utility model relates to the field of Venetian blind technology, specifically to an anti-slip structure for hollow glass Venetian blinds. Background Technology

[0002] Venetian blinds are typically made of aluminum alloy, wood, or bamboo with a painted finish. They are durable, easy to clean, non-aging, colorfast, provide sun shading, heat insulation, breathability, and fire resistance. Therefore, they are widely used in high-end office buildings, residences, hotels, villas, and other similar locations. They can also be paired with decorative stickers to create a more refined and elegant ambiance. Control methods include manual and electric adjustment, and the blind angle can be adjusted to the most suitable position.

[0003] Existing anti-slip structures for Venetian blinds typically involve a rope rotating around a large roller, while a smaller roller slides up and down. When the rope needs to be secured, it can be pulled to one side. The friction between the roller and the rope causes the smaller roller to slide upwards, thus clamping the rope between the smaller and larger rollers and fixing the position of the blinds. However, due to the continuous stress on the rope during long-term use, wear can easily occur on the rollers, causing the friction between the roller and the rope to gradually decrease. This weakens the anti-slip effect and may even lead to the rope loosening, making the height of the blinds unstable and affecting the user experience. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-6 This utility model provides a technical solution: an anti-slip structure for hollow glass venetian blinds, including a top box 1 and a venetian blind body 3, and also includes;

[0027] Bottom strip 10, which is set at the bottom of multiple louver bodies 3;

[0028] Pull cord 2 is installed inside top box 1 via multiple rollers, and one end of pull cord 2 passes through the bottom of top box 1 and is connected to the bottom strip 10 of louver body 3. Multiple louver bodies 3 can be height adjusted by raising and lowering pull cord 2.

[0029] Limiting component 100 is disposed inside top box 1 and is used to clamp pull rope 2 to form self-locking;

[0030] The limiting assembly 100 also includes a fixing plate 101 disposed inside the top box 1. A pair of moving rods 102 are slidably connected to the fixing plate 101. One end of the pair of moving rods 102 is provided with a moving plate 103, and the other end is provided with a mounting plate 108. A insertion plate 104 is provided on one side of the moving plate 103. A return spring 105 is also sleeved on the outer wall of the pair of moving rods 102. The two ends of the return spring 105 abut against the moving plate 103 and the fixing plate 101 respectively. A limiting member 106 is also provided inside the top box 1. The limiting member 106 has two limiting grooves 107 for the insertion plate 104 to be inserted. When the return spring 105 is in a compressed state (by... Figure 6As shown), the insert plate 104 will disengage from the inside of the limiting groove 107, and the pull rope 2 will be located between the moving plate 103 and the limiting member 106. Therefore, the height of the louver body 3 can be adjusted by pulling the pull rope 2.

[0031] When the pull rope 2 is adjusted and then released, the elastic force of the return spring 105 will push the moving plate 103 to move. The movement of the moving plate 103 will cause the insert plate 104 to be inserted into the limiting groove 107. At the same time, the insert plate 104 will push the outer surface of the pull rope 2, thereby clamping the pull rope 2 into the limiting groove 107 on the limiting member 106, thus fixing the position of the pull rope 2 and preventing the pull rope 2 from becoming loose, which greatly improves the stability of the anti-slip structure.

[0032] The top box 1 has a clearance hole 23. A connecting piece 20 is provided on one side of the mounting piece 108. A pull ring 21 is rotatably connected to the connecting piece 20. A connecting rope 22 is provided on the pull ring 21. One end of the connecting rope 22 extends out of the clearance hole 23. The spring force of the reset spring 105 can be controlled by pulling the connecting rope 22, so that the insert plate 104 can be easily inserted into or disengaged from the limiting groove 107, thereby achieving the clamping or release of the pull rope 2. The operation is simple and quick.

[0033] The top box 1 is also rotatably connected to the mounting cylinder 24, and the connecting rope 22 is wrapped around the outer circumference of the mounting cylinder 24. When the connecting rope 22 is pulled, the connecting rope 22 will drive the mounting cylinder 24 to rotate. Since the outer wall of the mounting cylinder 24 has an arc groove 25, the connecting rope 22 can be stably wrapped on the mounting cylinder 24, avoiding the situation where the connecting rope 22 slips off the mounting cylinder 24. At the same time, the mounting cylinder 24 is made of nylon, which has good wear resistance.

[0034] The top box 1 also has a mounting bracket 4 inside. A large roller 5 is rotatably connected to the mounting bracket 4. A pull rope 2 is wound around the outer circumference of the large roller 5. The mounting bracket 4 has a sliding hole 6 and a limiting hole 7 respectively, which are connected. A small roller 8 is rotatably connected to the mounting bracket 4, and the small roller 8 has the freedom to move along the height of the sliding hole 6 and the limiting hole 7. When the pull rope 2 is raised or lowered, it will rotate around the large roller 5, and at the same time, the small roller 8 can move along the height of the sliding hole 6 and the limiting hole 7. The pull rope 2 slides up and down within the hole 7. When it is necessary to fix the position of the pull rope 2, first pull the pull rope 2 to one side, so that the pull rope 2 and the small roller 8 are frictionally generated, thereby driving the small roller 8 to move upward. When the small roller 8 moves to the limiting hole 7, since the width of the limiting hole 7 is small, the position of the small roller 8 can be limited. At this time, the small roller 8 and the large roller 5 will clamp the pull rope 2, thereby fixing the position of the pull rope 2 and achieving the initial fixation of the pull rope 2 for subsequent operations.

[0035] In actual use, the connecting rope 22 can be pulled to one side, which will drive the mounting cylinder 24 to rotate. At the same time, the mounting plate 108 will drive the moving rod 102 to slide on the fixed plate 101. The sliding of the moving rod 102 will drive the moving plate 103 to move. The movement of the moving plate 103 will compress the reset spring 105. At the same time, the movement of the moving plate 103 will drive the insert plate 104 to disengage from the inside of the limiting groove 107. At this time, the reset spring 105 is in a compressed state.

[0036] After the insert plate 104 disengages from the limiting groove 107, the pull rope 2 will be located between the moving plate 103 and the limiting member 106. Therefore, the height of the louver body 3 can be adjusted by pulling the pull rope 2.

[0037] After the height of the louver body 3 is adjusted, the connecting rope 22 is released. At this time, the elastic force of the return spring 105 will be released, pushing the moving plate 103 to move towards the limiting member 106. The movement of the moving plate 103 will drive the insert plate 104 to insert into the limiting groove 107. At the same time, the insert plate 104 will push the outer surface of the pull rope 2, moving the pull rope 2 into the limiting groove 107, thereby clamping the pull rope 2 in the limiting groove 107, realizing the secondary fixation of the pull rope 2, preventing the pull rope 2 from easily loosening, and further improving the stability and reliability of the anti-slip structure.

[0038] In addition, the outer wall of the insert plate 104 and the inner wall of the limiting groove 107 are both provided with anti-slip textures, which increases the friction between the insert plate 104 and the limiting groove 107, effectively preventing the insert plate 104 from sliding or falling off in the limiting groove 107, further improving the anti-slip effect, avoiding the situation of the pull rope 2 becoming loose, and greatly improving the stability of the anti-slip structure.
