Abstract
Description
Technical Field
[0001] This utility model belongs to the field of curtains, specifically relating to a two-way opening and closing curtain structure. Background Technology
[0002] Spring-operated two-way curtains use springs to drive the pull cord, controlling the raising and lowering of the center and bottom rails. The spring tension increases with the length of the pull cord. To ensure the center and bottom rails remain suspended at their maximum extension and are not automatically pulled back by the springs, counterweights are added to the center and bottom rails to balance the tension. When the center rail is pulled up, the tension decreases as the pull cord retracts. However, insufficient tension often leads to incomplete closure of the center and support rails, resulting in light leakage. Furthermore, manually pulling the center rail to close it with the support rail causes significant noise when they collide, leading to a poor user experience with existing two-way curtains.

[0041] In some feasible embodiments, the shock-absorbing strip 22 is made of a flexible and deformable material, and the shock-absorbing strip 22 can produce elastic deformation and is inserted into the shock-absorbing strip groove 215. The shock-absorbing strip 22 includes an impact part 221. There is a certain gap between the impact part 221 and the surface of the middle rail 21, and this gap provides a buffer space for the deformation of the shock-absorbing strip 22 to ensure sufficient deformation during impact. The shock-absorbing strip can be of various shapes. Specifically, the cross-sectional shape of the shock-absorbing strip 22 is one or more of a straight line shape and an arc shape.
[0042] As a specific implementation manner of the embodiment of the present invention, please refer to Figures 1 to 13 simultaneously. The magnetic attraction component 6 is used to magnetically adsorb and close the support rail component 1 and the middle rail component 2 together. The magnetic attraction component 6 includes a first magnetic attraction part 61 connected to the support rail component 1 and a second magnetic attraction part 62 connected to the middle rail component 2. When the middle rail component 2 approaches the support rail component 1 to a certain distance, magnetic attraction is generated between the first magnetic attraction part 61 and the second magnetic attraction part 62, and the support rail component 1 and the middle rail component 2 are closed together. Specifically, the first magnetic attraction part 61 is a metal structural member and can be inserted into the lower function groove 113 provided on the lower end surface of the support rail 11. The second magnetic attraction part 62 is a magnet structural member. The magnet structural member is installed on the upper end surface of the middle rail 21 through a fixed clamping sleeve 63. That is, the magnet structural member is used to provide magnetic attraction. The fixed clamping sleeve 63 is used to fix the magnet structural member on the middle rail 21. The fixed clamping sleeve 63 can cooperate with the snap hole 218 of the middle rail 21 to fix the magnet structural member in the snap groove 211. The fixed clamping sleeve 63 is positioned through the cooperation of the snap hole 218 and the snap groove 211 to ensure that the magnet structural member is firmly installed.
[0043] As one specific implementation of this utility model, please refer to the following: Figures 1 to 13 The curtain 3 is located between the middle rail assembly 2 and the bottom rail assembly 4, and is used for light blocking. The curtain 3 has an upper insert 31, which is used to engage with the middle rail assembly 2. The curtain 3 has a lower insert 32, which is used to engage with the bottom rail assembly 4. The curtain has a cord hole 33, which is used to pass a pull cord.
[0044] As one specific implementation of this utility model, please refer to the following: Figures 1 to 13 The bottom rail assembly 4 is used to drive the curtain 3 to open and close downwards. The bottom rail assembly 4 is similar in structure to the middle rail assembly 2 and is placed in mirror image. The bottom rail assembly 4 has a built-in counterweight that matches the middle rail assembly 2 to ensure that the drive assembly 5 is balanced. The bottom rail assembly 4 does not need to connect the magnetic suction assembly 6 and the threading structure of the drive pull rope, so it does not have threading holes or buckle holes.
[0045] As one specific implementation of this utility model, please refer to the following: Figures 1 to 13 The drive assembly 5 is equipped with multiple pull cord drive structures, which do not interfere with each other. Specifically, it includes a first pull cord drive structure 51 and a second pull cord drive structure 52. The first pull cord drive structure 51 is used to drive the middle rail assembly 2 to open and close upwards. When the first pull cord drive structure 51 is tightened, the middle rail 21 rises (closes); when it is released, the middle rail 21 falls (opens). The second pull cord drive structure 52 is used to drive the bottom rail assembly 4 to open and close downwards. When the second pull cord drive structure 52 is released, the bottom rail assembly 4 falls (closes); when it is tightened, the bottom rail assembly 4 rises (opens). The drive assembly 5 is equipped with a pull cord bracket 53, which is used to position the pull cord and change the direction of pull cord movement. When the middle rail assembly 2 rises to the top and the bottom rail assembly 4 rises to the top, the curtain is in an upward closed state; when the middle rail assembly 2 rises to the top and the bottom rail assembly 4 falls to the bottom, the curtain is in an open state; when the middle rail assembly 2 falls to the bottom and the bottom rail assembly 4 falls to the bottom, the curtain is in a downward closed state. Multiple states of the curtain can be achieved through the combination of different drive modes of the multiple pull cord drive structures. It should be noted that the pull cord drive structure is a conventional coil spring pull cord drive structure used to drive the opening and closing of the curtains. The pull cord drive structure includes a pull cord, which is connected to the middle rail assembly 2 and the bottom rail assembly 4. The pull cord drive structure controls the extension and retraction of the pull cord through its internal coil spring mechanism, thereby driving the raising and lowering of the middle rail assembly 2 and the bottom rail assembly 4. The pull cord bracket 53 is used to change the direction of the pull cord's movement. The pull cord bracket 53 is installed in the center groove of the support rail and engages with the bracket hole for fixation.
[0046] This utility model provides a two-way opening and closing curtain structure. Compared with the prior art, by adding a magnetic component 6 between the support track assembly 1 and the middle track assembly 2, the problem of incomplete closure can be effectively solved. At the same time, the downward-extending lower baffle 115 in front of the support track assembly 1 effectively solves the problem of light leakage. By adding a flexible, deformable shock-absorbing strip 22 between the support track assembly 1 and the middle track assembly 2, the impact is buffered and decelerated to reduce collision noise.
[0047] 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.
