For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, it includes a first connecting rod 100, a second connecting rod 110, a first end 120, and a second end 130. The first end of the first connecting rod 100 is locked to the first end of the second connecting rod 110 via a connecting sleeve 140. The second end of the first connecting rod 100 is connected to one end of the first end 120. The second end of the second connecting rod 110 is connected to one end of the second end 130. A plurality of hooks 420 are arranged around the outer surface of the first end of the first connecting rod 100, and corresponding slots 450 are provided on the outer surface of the second connecting rod 110. The hooks 420 extend into the slots 450 to form a locking connection.

[0030] Specifically, one end of the first connecting rod 100 is connected to one end of the second connecting rod 110 via a connecting sleeve 140 to achieve a threaded internal locking connection. The connecting sleeve 140 has a threaded structure inside; when the first connecting rod 100 and the second connecting rod 110 are inserted and rotated, the threaded structure tightly engages the surfaces of the two rods, forming a secure locking effect. The second connecting rod 110 corresponds to the first connecting rod 100, and its outer surface is designed with a groove 450 that matches the hook 420 on the first connecting rod 100. The first end 120 and the second end 130 are respectively fixedly connected to the other ends of the first connecting rod 100 and the second connecting rod 110 for connecting other curtain rods. The outer surface of the first end of the first connecting rod 100 is surrounded by several elastic hooks 420, which naturally extend outwards when not compressed. The corresponding position on the second connecting rod 110 is designed with a groove 450 that matches the shape of the hook 420. After the first connecting rod 100 and the second connecting rod 110 are locked together by the connecting sleeve 140, the hook 420 can slide smoothly into the slot 450, further enhancing the stability of the connection and preventing loosening caused by external force.

[0031] Furthermore, the second end of the first connecting rod 100 is provided with a reduced external thread portion A200, and the first end 120 is provided with a corresponding reduced internal thread portion A210. The reduced external thread portion A200 and the reduced internal thread portion A210 are threadedly connected, thereby locking the first connecting rod 100 to the first end 120. The second end of the second connecting rod 110 is provided with a reduced external pressure portion B220, and the second end 130 is provided with a corresponding reduced internal thread portion B230. The reduced external thread portion B220 and the reduced internal thread portion B230 are threadedly connected, thereby locking the second connecting rod 110 to the second end 130. Specifically, the reduced external thread portion A200 of the first connecting rod 100 is inserted into the reduced internal thread portion A210 of the first end 120. By rotating the first connecting rod 100 or the first end 120, the threads between the two are tightly engaged, thereby achieving a locking connection. The reduced external thread B of the second connecting rod 110 is inserted into the reduced internal thread B230 of the second end 130. By rotating the second connecting rod 110 or the second end 130, the threads between them are tightly engaged, thus achieving a locking connection. The threaded connection design using reduced external and reduced internal threads ensures a stable and reliable connection between the first connecting rod 100 and the first end 120, and between the second connecting rod 110 and the second end 130, preventing loosening due to external forces.

[0032] Furthermore, the first end of the connecting sleeve 140 is embedded and tightly abutted within the first end of the connecting sleeve 140, and the second end of the second connecting rod 110 is embedded and tightly abutted within the second end of the connecting sleeve 140. A first abutting end 300 protruding outward is provided on the outer surface of the second end of the connecting sleeve 140, and the first end of the first connecting rod 100 abuts against the first abutting end 300; a second abutting end 310 protruding outward is provided on the second connecting rod 110 near its first end, and the second end of the connecting sleeve 140 abuts against the second abutting end 310. Specifically, when the first end of the connecting sleeve 140 is embedded into the second end of the first connecting rod 100, the two slide relative to each other and have friction, making them tightly connected. This continues until it abuts against the first abutting end 300. The second end of the connecting sleeve 140 and the second connecting rod 110 are similarly positioned; this design reduces the risk of loosening or damage to the connection due to long-term use or external forces.

[0033] Furthermore, both ends of the first end 120 and the second end 130 are provided with the same open end, so that the connecting rods can be connected to each other in pairs.

[0034] Furthermore, a circumferential collar 400 is fixed to the outer surface of the first connecting rod 100 near its first end. A support frame 410 extends from the collar 400 toward the second connecting rod 110, and the support frame 410 is connected to a hook 420. The hook 420 comprises a support column 430 and a claw 440. One end of the support column 430 is connected to the support frame 410, and the other end is perpendicularly connected to the claw 440 via a locking screw. The actuating part 460 of the claw 440 is sequentially provided with a rounded corner structure 470 and a right-angle structure 480. When the second connecting rod 110 approaches the first connecting rod 100, it sequentially passes through the rounded corner structure 470 and the right-angle structure 480, with the right-angle structure 480 engaging within a slot 450. Specifically, the direction of the support column 430 is parallel to that of the first connecting rod 100, and the hook 440 extends inward. When the first connecting rod 100 approaches the second connecting rod 110, it first passes through the channel enclosed by the hook 420 and smoothly extends under the rounded corner structure 470. When it reaches the designated slot 450, the right-angle structure 480 can extend into the slot 450 of the second connecting rod 110 to complete the locking and make the connection more stable.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
