[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-2 As shown, an adjustable rope knotting structure includes a fixed base 1, with a movable connecting seat 2 movably mounted on the lower side of the fixed base 1. The fixed base 1 has a rope-passing hole 11 for the rope body 3 to pass through. After passing through the rope-passing hole 11, the rope body 3 is connected to the movable connecting seat 2. A connecting seat position fine-tuning mechanism 4 is provided between the movable connecting seat 2 and the fixed base 1, allowing the movable connecting seat 2 to slide horizontally along the fixed base 1 and be mutually positioned. By connecting one end of the rope to the movable connecting seat through knotting or other methods, and by using the connecting seat fine-tuning mechanism to connect the movable connecting seat and the fixed base, the horizontal direction of the movable connecting seat relative to the fixed base can be finely adjusted, thus enabling adjustment of the entire knotting structure's position.

[0022] Furthermore, the fixing base 1 here is a long strip plate and is set horizontally, with the rope hole 11 vertically passing through one end of the fixing base 1. The movable connecting base 2 is provided with a fixing rope hole 21, and one end of the coiled rope 3 passes through the fixing rope hole 21 and is connected to the fixing rope hole 21 by a knot. Besides the knotting method, a screw can also be used to fix one end of the coiled rope 3 into the fixing rope hole 21.

[0023] Furthermore, the connecting seat position fine-tuning mechanism 4 here includes a horizontal sliding guide assembly and a position adjustment assembly disposed between the fixed seat 1 and the movable connecting seat 2 support.

[0024] The horizontal sliding guide assembly includes horizontal guide grooves 41 arranged on both sides of the fixed base 1 and extending along the axial direction of the fixed base 1. The movable connecting base 2 has horizontal sliders 42 on both sides, each corresponding to one of the horizontal guide grooves 41. The horizontal sliders 42 are slidably connected to the horizontal guide grooves 41. Preferably, the fixed base 1 has vertically arranged guide plates 43 on both sides, distributed along the axial direction of the fixed base 1. The upper ends of the guide plates 43 are bent in opposite directions to form guide portions 44. Below the guide portions 44, a horizontal guide strip 45 is located on the side of the fixed base 1, and the horizontal guide grooves 41 are formed between the guide portions 44 and the horizontal guide strips 45. The movable connecting base 2 has upwardly bent portions 46 on both sides, with one end of the bent portion 46 forming a horizontal slider 42. The guide portions 44 and the bent portions 46 are slidably connected on their inner sides. The horizontal sliding of the movable connecting base 2 and the fixed base is achieved by the mutual sliding of the horizontal sliders 42 and the horizontal guide grooves 41, and the mutual sliding of the inner sides of the guide portions 44 and the bent portions 46.

[0025] The position adjustment component here is either a multi-stage position adjustment component or a stepless position adjustment component. The multi-stage position adjustment component can be a ratchet-type position adjustment component, and the stepless position adjustment component can fix the movable connecting seat 2 to any position of the fixed seat 1 with screws.

[0026] For example, the position adjustment component here includes several positioning teeth 47 arranged sequentially on the lower side of the fixed base 1, and a positioning pawl 48 made of elastic material on one side of the movable connecting base 2 that cooperates with the positioning teeth 47. The positioning teeth 47 are evenly distributed at equal intervals, and each positioning tooth 47 is inclined downwards towards the end of the fixed base 1 away from the end with the rope hole 11. The positioning pawl 48 is integrally formed on one side of the movable connecting base 2 and is inclined in the same direction as the positioning teeth 47. The positioning pawl 48 is used to fix the position between any two positioning teeth 47, thus enabling fine-tuning from 0-25mm.

[0027] like Figure 3-4 As shown, in this embodiment, the knotting structure can be set inside the bottom beam 5 of the curtain slat, and fixed seats 1 are fixedly provided on the inner sides of both ends of the bottom beam 5. Several curtain slats 53 are provided above the bottom beam 5. The rope 3 passes through each curtain slat 53 in sequence and then enters the bottom beam 5 through the rope inlet hole 51 on the upper side of the bottom beam 5. The fixed seat 1 has a rope tube 52 connected to the rope hole 11 on the upper side, and the rope tube 52 is inserted into the rope inlet hole 51. Rope 3s are provided on both sides of the Venetian blind, and the rope 3s are respectively connected to the knotting structure located on the inner sides of both ends of the bottom beam 5. When the heights of the two ends of the bottom beam 5 are different, the heights of the two ends of the bottom beam 5 can be made the same by making slight adjustments to the horizontal direction of the movable connecting seat relative to the fixed seat.
