Description

Technical Field

[0001] This application relates to the field of roller blind curtain technology, specifically a roller blind beaded fastener. Background Technology

[0002] Beaded roller blinds are a widely used indoor sun shading product, generally consisting of mounting brackets, a roller tube, fabric, beaded strings, a control head, and a control tail. The beaded strings are usually connected to the control head; pulling the strings adjusts the height of the blind. In practical applications, because the beaded strings are a hanging, closed ring structure, they are prone to tangling and swaying in the wind, potentially colliding with walls or windows and causing noise. Therefore, securing the beaded strings is crucial for optimizing beaded roller blinds.

[0019] The main structural components of this application are a housing, an elastic component, a limiting post, and a slider. The structure is simple, making it easy for workers to install. Furthermore, the various components work together effectively. The limiting post passes through the strip groove of the slider to restrict slider offset while still allowing the slider to move in the first direction. By connecting the elastic component between the housing and the slider, when the pull bead is not pulled, the elastic component generates a downward force and tightens the pull bead through the slider, preventing it from tangling with or colliding with external objects. When the user pulls the pull bead downwards, the pull bead rotates in a cycle, generating an upward force that counteracts the downward force of the elastic component, allowing the user to pull the pull bead normally and adjust the roller blind.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] like Figures 1-5As shown, an embodiment of this application provides a roller blind beadlock fastener with a first direction and a second direction, including a housing 1, an elastic component 2, a limiting post 3, and a slider 4. The housing 1 is provided with a cavity 100; there are at least two limiting posts 3; the limiting posts 3 are located within the cavity 100; one end of the limiting post 3 is connected to the housing 1, and the other end of the limiting post 3 extends along the second direction.

[0030] One end of the elastic component 2 is connected to the box body 1, and the other end of the elastic component 2 is connected to the slider 4;

[0031] The slider 4 is located within the cavity 100 and can move along the first direction; the slider 4 is provided with a strip-shaped through groove 41; there are multiple strip-shaped through grooves 41, and each of the multiple strip-shaped through grooves 41 corresponds to a multiple of the limiting posts 3; the strip-shaped through groove 41 passes through the slider 4 along the second direction, and the length direction of the strip-shaped through groove 41 extends along the first direction; the other end of the slider 4 connected to the elastic component 2 is provided with an arc-shaped groove 42 for fixing the pull ball.

[0032] The main structural components of this application are a housing 1, an elastic component 2, a limiting post 3, and a slider 4. The structure is simple, making it easy for workers to install. At the same time, the various components work together reasonably. The limiting post 3 passes through the strip groove of the slider 4 to limit the slider 4 from deflection, while the slider 4 can still move in the first direction. By connecting the elastic component 2 between the housing 1 and the slider 4, when the pull bead is not pulled, the elastic component 2 generates a downward force and tightens the pull bead through the slider 4 to prevent it from getting tangled or colliding with external objects. When the user pulls the pull bead downward, the pull bead rotates in a cycle and generates an upward force to counteract the downward force of the elastic component 2, so that the user can pull the pull bead normally to adjust the roller blind.

[0033] Preferably, the housing 1 is further provided with a mounting ring 200; the mounting ring 200 extends along a first direction; one end of the spring passes through the mounting ring 200 and is connected to the housing 1.

[0034] More preferably, the slider 4 is further provided with a mounting hole 43 and a mounting post 44; the mounting hole 43 extends along a first direction; the mounting post 44 is disposed in the mounting hole 43; the length direction of the mounting post 44 extends along the first direction; the other end of the spring passes through the mounting hole 43 and is sleeved on the mounting post 44.

[0035] Specifically, in this embodiment, the elastic component 2 is a spring.

[0036] Under the preferred embodiment described above, the spring only needs to be placed inside the mounting ring 200 and the mounting hole 43 to complete the installation and will not detach. Furthermore, one end of the spring is fitted onto the mounting post 44 to prevent the spring from shifting within the mounting hole 43. It should be noted that there needs to be a gap between the mounting post 44 and the mounting ring 200 to allow the slider 4 to move up and down.

[0037] Specifically, the box body 1 includes a base plate 11 and a surrounding plate 12; the base plate 11 and the surrounding plate 12 are integrally formed, and the surrounding plate 12 surrounds the four sides of the base plate 11 to form the cavity 100; the surrounding plate 12 is provided with a bead pull inlet 121 and a bead pull outlet 122 on one side along the first direction; the bead pull inlet 121 and the bead pull outlet 122 are both connected to the cavity 100.

[0038] In practical applications, the pull ball enters the cavity 100 from the pull ball inlet 121, circles the arc-shaped groove 42 of the slider 4, and exits from the pull ball outlet 122, then connects to the control head of the peripheral device, thus forming a circular loop. It should be noted that in this embodiment, the pull ball only contacts the arc-shaped groove 42 of the slider 4, thereby reducing resistance.

[0039] In practical applications, to secure the beadlock holder to the outside, the base plate 11 is provided with mounting holes 111 for installation and fixation. In this embodiment, there are two mounting holes 111. Of course, this embodiment is not limited to the fixing method; it can be fixed by bolts or adhesive as needed.

[0040] Preferably, the device further includes a cover plate 5, which is detachably connected to the box body 1 and used to close the cavity 100; the cover plate 5 is provided with a positioning ring 52; the positioning ring 52 and the limiting post 3 correspond one-to-one; when the cover plate 5 and the box body 1 are connected, one end of the limiting post 3 extends in a second direction into the positioning ring 52. In this preferred embodiment, the cover plate 5 not only serves to close the cavity 100 and protect the internal structure, but also enhances the appearance.

[0041] More preferably, the surrounding plate 12 is provided with locking holes 123; the cover plate 5 is provided with inserts 51; the inserts 51 have barbs; the positions of the inserts 51 and the locking holes 123 correspond, and when the inserts 51 are inserted into the locking holes 123, the barbs fasten the locking holes 123; in this embodiment, there are three locking holes 123, which are respectively arranged on the bottom side and the two sides; correspondingly, there are also three inserts 51. Under this preferred embodiment, the cover plate 5 is fixed to the surrounding plate 12 by the inserts 51 and the locking holes 123, realizing detachable installation. Of course, this embodiment does not limit the detachable installation method of the cover plate 5, and those skilled in the art can also use bolts for fastening or other commonly used locking structures.

[0042] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
