Description

Technical Field

[0001] This utility model relates to the technical field of curtain components, specifically a rotary control head. Background Technology

[0002] With social development and progress, curtain products are constantly being updated. Curtains with beaded or pull cord operation pose safety hazards to children, who can easily get tangled in the cords or beads while playing, even leading to serious consequences such as suffocation. Therefore, cordless curtains have gradually become a popular choice for customers. However, motorized curtains are expensive, with high manufacturing costs, complex installation processes, and maintenance costs, excluding many families with limited budgets. Cordless spring curtains better meet market demand. However, existing cordless spring curtains rely on elasticity for opening and closing, making it difficult to stop precisely at any height like corded curtains. They can usually only be fully opened or fully retracted, or stop at a few fixed positions. To address this, we have designed a rotating rod control head. Utility Model Content

[0003] The purpose of this invention is to provide a rotary control head that has the advantage of preventing curtains from automatically sliding down. It solves the problem that spring curtains rely on elastic force to open and close, making it difficult to stop precisely at any height like corded curtains. They can usually only be fully opened or fully retracted, or stop at a few fixed positions, which cannot meet the user's refined needs for light adjustment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotating rod control head, comprising a head-controlling mechanism, a plug, and a round-headed screw. The head-controlling mechanism has a connecting mechanism at its bottom, and a rotating mechanism at its bottom. The head-controlling mechanism includes a universal torsion core. The connecting mechanism includes a long aluminum rod, and the rotating mechanism includes a second short aluminum rod. The second short aluminum rod is movably mounted on the top of the plug. A fifth connecting shaft is installed through the top of the second short aluminum rod. A second connecting shaft is movably mounted on the top of the long aluminum rod, and a first connecting shaft is movably mounted on the top of the second connecting shaft. A torsion spring is movably sleeved on the surface of the universal torsion core, and a housing is movably mounted on the front side of the universal torsion core.

[0005] Preferably, a sleeve is movably fitted on the front side of the outer shell surface, an end cap is movably installed on the front side of the sleeve, and a second flat-head screw is installed through the front side of the sleeve.

[0006] Preferably, a cover is movably mounted on the rear side of the universal torsion core, a bracket is fixedly mounted on the rear side of the cover, and a first flat-head screw is installed through the rear side of the bracket.

[0007] Preferably, a first connecting shaft is movably sleeved on the top of the surface of the first connecting shaft, and a universal joint is movably mounted on the top of the first connecting shaft.

[0008] Preferably, a fourth connecting shaft is movably mounted on the top of the fifth connecting shaft, and a first short aluminum rod is movably sleeved on the surface of the fourth connecting shaft.

[0009] Preferably, a third connecting shaft is installed through the left side of the first short aluminum rod, and a second connecting shaft is movably installed on the surface of the third connecting shaft, and the number of round-headed screws is several.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model, through the cooperation of a shell, torsion spring, universal torsion core, buckle cover, bracket, first flat-head screw, universal rotating shaft, round-head screw, first connecting shaft, first connecting shaft, second connecting shaft, long aluminum rod, second connecting shaft, third connecting shaft, first short aluminum rod, fourth connecting shaft, fifth connecting shaft, second short aluminum rod, second flat-head screw, end cap, and sleeve, can prevent the curtain from automatically slipping down. When the curtain falls, it applies a force to the sleeve, causing the sleeve to rotate. Then, the column inside the sleeve applies a force to the torsion spring. The outer diameter of the torsion spring increases under force, applying a force to the outer shell tube wall, blocking the rotation of the sleeve and preventing the curtain from continuing to slide down.

The first connecting shaft 13 facilitates the connection between the first connecting shaft 12 and the second connecting shaft 14. The cooperation of the second short aluminum rod 22, the first short aluminum rod 19, and the long aluminum rod 15 facilitates the user to rotate the universal joint 10. The plug 18 can seal the bottom of the second short aluminum rod 22, and at the same time, it also facilitates the user to rotate the second short aluminum rod 22.

[0020] Please see Figure 1 , Figure 2 and Figure 3A sleeve 25 is movably fitted on the front side of the outer shell 4. An end cap 24 is movably installed on the front side of the sleeve 25. A second flat-head screw 23 is installed through the front side of the sleeve 25. By setting the second flat-head screw 23, the end cap 24 can be fixed so that the end cap 24 can be installed on the sleeve 25.

[0021] Please see Figure 1 , Figure 2 and Figure 3 A cover 7 is movably installed on the rear side of the universal torsion core 6, and a bracket 8 is fixedly installed on the rear side of the cover 7. A first flat-head screw 9 is installed through the rear side of the bracket 8. By setting the first flat-head screw 9, the cover 7 can be installed so that the cover 7 can be installed on the bracket 8.

[0022] Please see Figure 1 , Figure 2 and Figure 4 The first connecting shaft 12 is movably sleeved on the top of the surface of the first connecting shaft 13, and the universal joint shaft 10 is movably mounted on the top of the first connecting shaft 12.

[0023] Please see Figure 1 , Figure 2 and Figure 5 The top of the fifth connecting shaft 21 is movably mounted with the fourth connecting shaft 20, and the surface of the fourth connecting shaft 20 is movably sleeved with the first short aluminum rod 19. Through the cooperation of the fifth connecting shaft 21 and the fourth connecting shaft 20, it is convenient to connect the second short aluminum rod 22 with the first short aluminum rod 19.

[0024] Please see Figure 1 , Figure 2 and Figure 5 A third connecting shaft 17 is installed through the left side of the first short aluminum rod 19. A second connecting shaft 16 is movably installed on the surface of the third connecting shaft 17. There are several round-headed screws 11. The first short aluminum rod 19 and the long aluminum rod 15 are connected through the cooperation of the third connecting shaft 17 and the second connecting shaft 16.

[0025] In use, the user places the round tube rotating rod component on the sleeve 25 to install the curtain component. During installation, a force is applied to the sleeve 25. When the sleeve 25 rotates, the upright inside the sleeve 25 applies a force to the torsion spring 5. The increased outer diameter of the torsion spring 5 exerts a force on the wall of the outer casing 4, preventing the sleeve 25 from rotating. When the universal shaft 10 rotates, it drives the universal torsion core 6 to rotate via gear transmission. The universal torsion core 6 applies a force to the torsion spring 5, reducing its outer diameter, allowing the universal torsion core 6 to drive the sleeve 25 to rotate normally. When the curtain moves, the forces from the fabric and the lower beam are counteracted by the resistance of the torsion spring 5 and the outer casing 4, preventing the curtain from sliding down automatically or the curtain from rotating with the rotating rod. When the rotating rod is used to open and close the curtain, the torsion spring 5 contracts to cancel the assist, allowing the rotating rod to operate the curtain normally. The user then connects the curtain using the second short aluminum rod 22, the first short aluminum rod 19, and the long aluminum rod 15. The rotation mechanism allows the universal swivel shaft 10 to rotate even when the aluminum rod is tilted, preventing the curtains from obstructing the rotation of the swivel. First, the user connects and assembles the first connecting shaft 12, the first connecting shaft 13, and the second connecting shaft 14 using round-head screws 11. Then, the user sequentially connects and assembles the second connecting shaft 16, the third connecting shaft 17, the fourth connecting shaft 20, and the fifth connecting shaft 21 using round-head screws 11. Next, the second connecting shaft 14 and the second connecting shaft 16 are installed onto the long aluminum rod 15, while the third connecting shaft 17 and the fourth connecting shaft 20 are installed onto the first short aluminum rod 19, allowing the rotating components to deform. After completion, the user installs the fifth connecting shaft 21 and the plug 18 onto the second short aluminum rod 22. This prevents the curtains from being too small for the window frame during rotation, thus ensuring the universal swivel shaft 10 can rotate and be opened / closed by pulling the swivel outwards and engaging with the connecting components.

[0026] In summary, this rotating control head, through the cooperation of the control head mechanism 1, connecting mechanism 2, rotating mechanism 3, outer shell 4, torsion spring 5, universal torsion core 6, buckle cover 7, bracket 8, first flat head screw 9 and universal rotating shaft 10, solves the problem that spring curtains rely on elastic force for opening and closing, making it difficult to stop precisely at any height like corded curtains. They can usually only be fully opened or fully retracted, or stop at a few fixed positions, failing to meet users' refined needs for light adjustment.
