Description

Technical Field

[0001] This utility model belongs to the field of roller blind technology, and in particular relates to a positioning structure for an idler wheel of a roller blind. Background Technology

[0002] An idler gear, also known as an intermediate gear, intermediate wheel, or bridge gear, is a gear that acts as a transmission gear between two non-contacting transmission gears. It meshes with both gears to change the rotation direction of the driven gear.

[0003] In a roller blind system, an idler wheel can change the rotation direction of the gears on the roller blind shaft, ensuring that the roller blind can be rolled up and down in the expected direction, and reducing vibration and noise during the rolling up and down process, thereby improving the stability and reliability of the system.

[0004] However, many idler rollers are prone to loosening or even falling off during installation due to insufficient securing methods. This not only affects the normal operation of the roller blind system but may also pose a potential threat to user safety. Furthermore, idler rollers may experience wear and increased noise after a period of use, significantly shortening their lifespan. This not only increases maintenance costs for users but also impacts the overall performance of the roller blind system and the user experience. Utility Model Content

[0005] The purpose of this invention is to address the common problem of idler wheels loosening or even detaching during installation due to insufficient fixing. This not only affects the normal operation of the roller blind system but also poses a potential safety threat to users. Furthermore, idler wheels experience wear and increased noise after a period of use, significantly shortening their lifespan. This increases maintenance costs for users and negatively impacts the overall performance and user experience of the roller blind system. Therefore, this invention proposes a positioning structure for the idler wheels of a roller blind shaft.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a positioning structure for an idler wheel of a roller shutter, comprising:

[0007] A die-cast bracket with an internal mounting groove, wherein the stamped shim is installed in the mounting groove;

[0008] A wear-resistant rotary disc is snapped onto the stamping pad, and the wear-resistant rotary disc is provided with mounting holes, in which the idler wheel is installed.

[0009] As a further description of the above technical solution:

[0010] Fixing blocks are provided at the four corners of the mounting slot, and fixing holes are provided on the fixing blocks. Connecting holes are provided around the stamping pad, and metal screws pass through the connecting holes and are fixed in the fixing holes.

[0011] As a further description of the above technical solution:

[0012] The stamping pad is provided with a protrusion, and a snap-fit ​​hole is provided in the protrusion. The stamping pad is provided with an abutment groove and a downwardly extending snap-fit ​​groove. The protrusion abuts in the abutment groove, and the snap-fit ​​groove is located in the snap-fit ​​hole.

[0013] As a further description of the above technical solution:

[0014] The snap-fit ​​groove is provided with snap-fit ​​blocks on both sides, and the snap-fit ​​blocks snap onto the snap-fit ​​hole wall.

[0015] As a further description of the above technical solution:

[0016] The wear-resistant rotary disc is made of plastic.

[0017] As a further description of the above technical solution:

[0018] The wear-resistant rotary disc has a notch.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] In this invention, by combining a die-cast bracket with a stamped shim, the wear-resistant rotary disc is snapped onto the stamped shim, and the idler wheel is installed in the mounting hole on the wear-resistant rotary disc. This structure, through the connection of the wear-resistant rotary disc, the die-cast bracket, and the stamped shim, improves the stability and accuracy of the idler wheel positioning, and avoids the problem of the idler wheel becoming loose. At the same time, the wear-resistant rotary disc is made of plastic, which makes the product life longer and the appearance more beautiful and three-dimensional. Attached Figure Description
