Description

Curtain drawstring storage mechanism

technical field

The utility model relates to a curtain drawstring storage mechanism, in particular to a curtain drawstring storage mechanism which utilizes the elastic recovery force of a spiral torsion spring to accommodate the curtain drawstring.

Background technique

Curtains are sun-shading structures that are often seen in ordinary homes. In order to cope with the operation of the curtains, there are often curtain drawstrings exposed on the outside for users to operate and use, so that users can directly stretch when pulling and placing the curtain drawstrings. Or shrink the curtain to control the sunshade area of the curtain. Therefore, the curtain drawstring has always been an extremely important part in the structural design of the curtain. However, the exposed curtain drawstring is for the convenience of controlling, stretching and contracting the curtain, and often presents a state of hanging below the curtain. Potentially dangerous, because children tend to run around when they play, and also like to hide in corners or shelters, so children have a great chance of crawling close to the curtains, and it is very likely that children's heads will pass through The action of pulling the rope of the curtain occurs, resulting in a fatal crisis of strangulation.

In addition, the curtain drawstring storage mechanism used in ordinary households must wind the drawstring by itself every time, which is not convenient, and it is easy to forget to wrap the drawcord for storage, resulting in danger.

The inventor is based on the fact that there are occasional accidents in which children are injured and fatally injured by curtain pull cords at home and abroad, which often cause great harm. Therefore, the inventor has been engaged in research and development for many years and has many practical experiences.

Please refer to Figure 4, which is an enlarged schematic diagram of a partial structure of a preferred embodiment of the curtain drawstring storage mechanism of the present invention, and the components in this figure that are the same as those in Figures 2 and 3 will not be described again. In the figure, it is to undertake the above-mentioned action, and then use a Phillips screwdriver (not shown in the figure) to vertically put the curtain pull cord 2 into the through hole 134 located in the middle of the central axis 13, which is represented by a square hole in this embodiment , but not limited thereto, and use a cross screwdriver to place the drawstring separator 17 on both sides of the square hole, and pass the bolt 18 through the bolt hole 171 of the drawstring divider 17 to bolt the drawstring divider 17 Close on the central axis 13 and fix, the curtain stay cord 2 is just limited in the middle of the central axis 13, but can be pulled freely to carry out the action of winding and receiving the rope.

Please refer to Figure 5, which is a schematic diagram of the operation of the preferred embodiment of the curtain drawstring storage mechanism of the present invention, and the same parts as those in Figure 2 and Figure 3 will not be described again. In the figure, when the curtain stay cord 2 is pulled to the bottom or when the knob 14 is rotated and put into the curtain stay cord 2 for the first time, the curtain stay cord 2 can perform the action of opening or closing the curtain, but it is pulled The rope separator 17 is limited to the position of the through hole (not shown in this figure) in the center of the central shaft 13 . At the same time, the spiral torsion spring 15 is tightened to store an elastic restoring force.

After the above actions are completed, after the curtain is opened or closed to the position, the operator presses the knob 14 to displace the central axis 13 toward the spring leaf 16. State, to release the energy of the spiral torsion spring 15, utilize the elastic recovery force of the spiral torsion spring 15 to drive the central shaft 13 to rotate clockwise, so that the curtain stay cord 2 is wound on the central shaft 13. When the spiral torsion spring 15 fully releases the elastic restoring force, the curtain stay cord 2 is rolled up to a certain length, so as to complete the purpose of accommodating the curtain stay cord 2 .

Once the operator presses the knob 14, the volute torsion spring 15 releases energy, and uses the elastic restoring force of the volute torsion spring 15 to store the curtain cord 2. 13 Winding the curtain drawstring 2 and moving upwards, so as to improve the convenience of automatic storage of the curtain drawstring storage mechanism 1 .

Afterwards, if you need to reuse it, you only need to hold and pull down the curtain cord storage mechanism 1 until the curtain cord 2 is elongated to the zero point marked on the first housing 11 (not shown in this figure), and due to the pull down The action causes the central shaft 13 to rotate counterclockwise and re-tighten the volute torsion spring 15. At this time, the window flap pull cord 2 is lengthened and no longer wound on the central shaft 13. At this time, the operator can freely use the window Low pull cord 2 performs the action of pulling open or pulling the curtain.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those skilled in the art can use the technical content disclosed above to make some changes or modify them into equivalent embodiments without departing from the technical solution of the present utility model.
