All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of the embodiments of the present invention, it should be noted that the terms "upper" and "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0035] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Example 1:

[0037] Please see Figure 1-6 This invention provides a quick-installable Venetian blind bottom track connector, comprising: an upper connector 1 and a lower connector 2. The upper connector 1 is positioned above the lower connector 2. The upper connector 1 and the lower connector form a cross shape when viewed from above. A connecting section 3 is provided between the upper connector 1 and the lower connector 2. The connecting section 3, the upper connector 1, and the lower connector 2 are an integral structure. Ladder rope fixing holes 4 are respectively provided at both ends of the bottom of the upper connector 1. A through hole 5 is provided on the upper connector 1. The through hole 5 passes through the upper connector 1, the connecting section 3, and the lower connector 2 sequentially from top to bottom. A pin 6 is provided on the lower connector 2. A lifting belt 7 passes through the through hole 5 and is connected to the pin 6.

[0038] Specifically, the lower buckle 2 is provided with a shaft hole 10, and the pin 6 is located in the shaft hole 10.

[0039] Specifically, the connecting section 3 is cylindrical. The cylindrical shape facilitates the rotation of the connecting buckle on the bottom rail.

[0040] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the connecting buckle consists of an upper buckle seat and a lower buckle seat, and the upper and lower buckle seats are cross-shaped. During installation, the lower buckle seat only needs to pass through the connecting hole on the bottom rail and rotate 90 degrees, so that the connecting buckle can be quickly installed on the bottom rail. The rotating assembly method connects to the bottom rail, which can facilitate quick and easy assembly and disassembly. The ladder rope fixing hole and pin can fix the ladder rope and lifting belt. A single connecting buckle can fix the ladder rope and lifting belt, which can reduce the number of connecting buckles used, thereby improving installation efficiency and reducing production and manufacturing costs.

[0041] Example 2:

[0042] See Figure 1-6The figure shows a quick-installable Venetian blind bottom track connecting buckle provided by Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: At least one tightening component 8 is provided at each end of the top of the lower buckle seat 2. The tightening component 8 includes a tightening rod 81 and a first spring 82. One end of the first spring 82 is connected to the lower buckle seat 2, and the other end of the first spring 82 is connected to the tightening rod 81. In this way, the tightening rod and the upper buckle seat cooperate to abut against the upper and lower surfaces of the bottom track respectively, thereby making the connecting buckle more secure and less prone to loosening.

[0043] Example 3:

[0044] See Figure 1-6 The figure shows a quick-installable Venetian blind bottom rail connecting buckle provided by Embodiment 3 of the present invention. This embodiment further improves upon the above embodiments by providing the following technical solution: The lower buckle seat 2 is provided with an installation groove 9, the first spring 82 is located within the installation groove 9, and the tightening rod 81 is movably connected to the installation groove 9. The top of the tightening rod 81 has an inclined surface. Through the inclined surface, during the rotation of the lower buckle seat, one side of the inclined surface of the tightening rod gradually contacts the bottom rail, compressing the spring and entering the installation groove, preventing the tightening rod from obstructing the rotation of the lower buckle seat. After the lower buckle seat has rotated to its position, the spring allows the tightening rod to hold the bottom rail in place.

[0045] Example 4:

[0046] See Figure 1-6 The figure shows a quick-installable Venetian blind bottom track connecting buckle provided by Embodiment 4 of the present invention. This embodiment further improves upon the above embodiments by the following technical solution: Two connecting components 11 are provided on the lower buckle seat 2, and the two ends of the pin 6 are respectively connected to the corresponding connecting components 11. Each connecting component 11 includes a connecting rod 111 and a connecting seat 112. The connecting rod 111 is connected to the lower buckle seat 2, and the connecting seat 112 is connected to the connecting rod 111. The end of the pin 6 is inserted into the connecting seat 112. The connecting rod is a screw, threadedly connected to the lower buckle seat. By rotating the screw, the position of the screw can be adjusted, thereby adjusting the position of the pin, thus keeping the lifting belt in a tensioned state. In another embodiment, the connecting rod 111 is movably connected to the lower buckle seat 2, and a second spring 12 is provided on the connecting rod 111, located between the lower buckle seat 2 and the connecting seat 112. This allows for adaptive adjustment of the screw position.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
