Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, and in particular relates to an anti-jamming roller shutter louver. Background Technology

[0002] In the fields of architectural decoration and indoor / outdoor sun shading, roller blinds and Venetian blinds are widely used in various settings such as residences, offices, and commercial stores due to their flexible light-blocking adjustment and space-saving installation features. Traditional roller blinds and Venetian blinds mainly consist of an outer shell, a rotating rod, and slats wound around the rotating rod. The slats are rolled up and down by rotating the rod in both directions to meet users' different needs for light, privacy, and ventilation.

[0003] However, during long-term use, traditional roller blinds and Venetian blinds have gradually revealed two major problems that seriously affect their user experience and lifespan. The slats are prone to stains, and the traditional structure lacks dedicated cleaning parts, making it difficult to remove stains in a timely manner. This not only affects the appearance but also corrodes the slat material, accelerates aging, shortens the lifespan, and increases maintenance and replacement costs. The movement of the slats lacks stable support and guidance, making them prone to deviation and sagging, generating noise, causing wear, and even causing jamming, affecting functionality and reducing the user experience.

[0004] There is an urgent need for improvement, so we propose an anti-jamming type roller shutter venetian blind. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an anti-jamming roller blind / venetian blind. This design achieves a close fit between the cleaning component and the slats, allowing for timely removal of stains from the slat surface, preventing damage to the appearance, reducing material corrosion, extending service life, and lowering maintenance and replacement costs. The auxiliary component supports and guides the slats, preventing them from shifting or sagging, avoiding friction and compression, eliminating noise, reducing wear, solving jamming problems, ensuring functionality, improving user experience, and simultaneously preventing damage to the drive mechanism, thus reducing maintenance costs.

[0006] In view of this, the present invention provides an anti-jamming roller blind, including a housing, a rotating rod rotatably connected to the inner side of the housing, and a curtain slat wound on the rotating rod; A positioning frame is fixedly connected to the inner wall of the top of the outer shell. A cleaning component is detachably connected to the other end of the positioning frame via a quick-release assembly. The cleaning end of the cleaning component is in contact with one side of the curtain slat. The cleaning component is used to clean the curtain slat. An auxiliary component is rotatably mounted on the inner side of the housing. The auxiliary component is attached to the other side of the curtain slat and cooperates with the cleaning component. The auxiliary component is used to support the curtain slat and guide its movement.

[0007] Furthermore, the positioning frame has a positioning groove on the inner side of its bottom end, and the quick-release assembly includes a positioning rod. The outer side of the positioning rod is integrally formed with multiple protrusions, and the inner sidewall of the positioning groove is provided with grooves that are adapted to each of the protrusions. The shape and size of the grooves are adapted to the shape and size of the corresponding protrusions.

[0008] Furthermore, the cleaning component includes a connecting bracket, the top end of which extends into the positioning groove of the positioning frame, and the top end of the connecting bracket is fixedly connected to the bottom end of the positioning rod.

[0009] Furthermore, the connecting bracket has an arc-shaped plate structure, and the outer arc surface of the connecting bracket is close to the side of the guide curtain.

[0010] Furthermore, an installation cylinder is fixedly connected to the bottom end of the connecting bracket, and a brush roller is rotatably connected to the inner side of the installation cylinder via a bearing, with the bristles of the brush roller abutting against the guide curtain.

[0011] Furthermore, both ends of the outer casing are fixedly connected to the mounting brackets by screws, and the two mounting brackets are arranged opposite to each other.

[0012] Furthermore, the inner side of the outer casing is fixedly connected to the mounting seats at both ends of the guide rod by bolts, and the auxiliary component includes a guide roller rotatably connected to the outer side of the guide rod. The guide roller rotates freely around the axis of the guide rod and is disposed on one side of the curtain slat.

[0013] The beneficial effects of this utility model are: By incorporating a cleaning component and an auxiliary component within the outer casing, dual practical value is achieved. On one hand, the cleaning component continuously cleans one side of the slats during rolling or unrolling, effectively removing dust and impurities adhering to the slat surface. This prevents long-term accumulation of stains from affecting the cleanliness of the blinds' appearance and reduces the erosion of the slat material by stains, extending the slats' lifespan. On the other hand, the auxiliary component fits snugly against the other side of the slats, providing stable support and preventing the slats from shifting or sagging due to their own weight or external forces during movement. It also guides the slats to move smoothly along a preset trajectory, preventing friction or jamming between the slats and the inner wall of the casing or other components. This significantly improves the smoothness of the roller blinds' operation and ensures a superior user experience. Attached Figure Description

[0020] Reference Figures 1 to 5 A type of anti-jamming roller blind includes an outer shell 1, a rotating rod 12 rotatably connected to the inner side of the outer shell 1, and a curtain slat 13 wound on the rotating rod 12; A positioning frame 2 is fixedly connected to the inner wall of the top of the outer casing 1. A cleaning component is detachably connected to the other end of the positioning frame 2 via a quick-release assembly. The cleaning end of the cleaning component is attached to one side of the curtain slat 13. The cleaning component is used to clean the curtain slat 13. An auxiliary component is rotatably provided inside the housing 1. The auxiliary component is attached to the other side of the curtain slat 13 and cooperates with the cleaning component. The auxiliary component is used to support the curtain slat 13 and guide the movement of the curtain slat 13.

[0021] In this application, the rotating rod 12 is rotatably connected to the inner side of the housing 1 via a bearing. When the rotating rod 12 rotates to cause the curtain 13 to roll up or unfold, the cleaning end of the cleaning component is continuously in contact with one side of the curtain 13, simultaneously cleaning the dust on the surface of the curtain 13. The auxiliary component is in contact with the other side of the curtain 13, which not only supports the curtain 13 to keep it flat, but also reduces the resistance of the curtain 13 to movement by rolling, and guides the direction of movement of the curtain 13. The two work together to ensure that the curtain 13 moves smoothly without jamming, and at the same time completes the cleaning. The quick-release component facilitates the quick disassembly and installation of the cleaning component, which is convenient for later maintenance.

[0022] In the example of this application, the positioning frame 2 has a positioning groove 3 on the inner side of its bottom end. The quick-release assembly includes a positioning rod 5. Multiple protrusions 6 are integrally formed on the outer side of the positioning rod 5. The inner sidewall of the positioning groove 3 is provided with grooves 4 that are adapted to each of the protrusions 6. The shape and size of the grooves 4 are adapted to the shape and size of the corresponding protrusions 6.

[0023] As a preferred example of this utility model, when installing the cleaning component, the protrusion 6 on the outside of the positioning rod 5 is aligned with the groove 4 on the inside of the positioning slot 3 and inserted. The matching structure between the protrusion 6 and the groove 4 can quickly position the cleaning component and prevent it from shifting laterally. When disassembling, the cleaning component and the positioning frame 2 can be separated by simply pulling out the positioning rod 5. No tools are required, which enables quick disassembly and assembly of the cleaning component and improves the convenience of maintenance.

[0024] In the example of this application, the cleaning component includes a connecting bracket 7, the top end of which extends into the positioning groove 3 of the positioning frame 2, and the top end of the connecting bracket 7 is fixedly connected to the bottom end of the positioning rod 5.

[0025] As a preferred example of this utility model, after the positioning rod 5 is fixed in the positioning groove 3 by the quick-release structure, the connecting bracket 7 serves as an intermediate connecting member to transmit the fixing force of the positioning rod 5 to the cleaning component below, ensuring that the cleaning component is stably installed on the positioning frame 2 as a whole, and preventing the cleaning component from becoming loose when the curtain 13 moves.

[0026] In the example of this application, the connecting bracket 7 has an arc-shaped plate structure, and the outer arc surface of the connecting bracket 7 is close to the side of the guide curtain 13.

[0027] As a preferred example of this utility model, the bending direction of the arc-shaped connecting bracket 7 is adapted to the winding or unfolding path of the curtain slat 13, so that the brush roller 9 installed below can always keep in contact with the surface of the curtain slat 13. Even if the curtain slat 13 has a slight curvature change, the contact stability of the cleaning end can be guaranteed, and cleaning dead corners can be avoided.

[0028] In the example of this application, the bottom end of the connecting bracket 7 is fixedly connected to the mounting cylinder 8, and the inner side of the mounting cylinder 8 is rotatably connected to the brush roller 9 through the bearing. The bristles of the brush roller 9 form a reasonable contact pressure with the guide curtain 13 and cooperate to continuously move relative to each other.

[0029] As a preferred example of this utility model, when the curtain slat 13 is rolled up or unrolled, its surface comes into contact with the brush roller 9 to generate friction, which drives the brush roller 9 to rotate around the bearing inside the mounting cylinder 8; the rotating brush roller 9 cleans the dust and impurities on the surface of the curtain slat 13 by friction between the bristles and the curtain slat 13, thus achieving synchronous cleaning of the curtain slat 13.

[0030] In the example of this application, the two ends of the outer casing 1 are fixedly connected to the mounting brackets 16 by screws, and the two mounting brackets 16 are arranged opposite to each other.

[0031] As a preferred example of this utility model, two oppositely arranged mounting brackets 16 are fixed to both ends of the housing 1 by screws to form a symmetrical support structure, which facilitates the closure of the openings on both sides of the housing 1.

[0032] In the example of this application, the inner side of the outer casing 1 is fixedly connected to the mounting seats 17 at both ends of the guide rod 14 and the rotating rod 12 by bolts. The auxiliary component includes a guide roller 15 rotatably connected to the outer side of the guide rod 14. The guide roller 15 rotates freely around the axis of the guide rod 14. The guide roller 15 is disposed on one side of the curtain slat 13. The guide roller 15 is used to guide the movement direction of the curtain slat 13 during the winding or unfolding process to ensure the smoothness of the movement of the curtain slat 13.

[0033] As a preferred example of this utility model, during the winding or unfolding of the curtain slat 13, the guide roller 15 contacts one side of the curtain slat 13, and the rotation of the guide roller 15 guides the curtain slat 13 to move along a preset path to avoid the curtain slat 13 from deviating.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
