车库门一般分为手动车库门和自动车库门，由于手动车库门开、关麻烦，且容易坏，目前都使用自动车库门。自动车库门中使用更多的是卷帘车库门，因为卷帘车库门制作高度可达到9米 14米，制作宽度4米 12米，抗风能力达到11级。所以，卷帘车库门的配件都需要具有较高的强度和韧性。例如卷帘车库门的帘片采用高强度铝合金双(单)层挤压成型。目前，车库门用平轮是铁质的，重量较重，使用寿命短，成本高，制作环境脏乱，对环境有一定的污染性。
Garage door is generally divided into manual garage door and automatic garage door. As manual garage door is difficult to open and close, and easy to break, automatic garage door is used at present. The most widely used automatic garage door is rolling shutter garage door, because the maximum production height of rolling shutter garage door can reach 9 m 14 m, the maximum production width is 4 m 12 m, and the maximum wind resistance capacity reaches 11 level. Therefore, rolling shutter garage door accessories need to have a high strength and toughness. For example, the curtain of rolling shutter garage door adopts high strength aluminum alloy double (single) layer extrusion molding. At present, the flat wheel for garage door is made of iron, heavy weight, short service life, high cost, messy production environment, which has certain pollution to the environment.
The utility model relates to a flat wheel for garage door with light weight, long service life, low cost and basically no pollution. The flat wheel for garage door comprises a flat wheel body, a cylindrical surface surrounded by steel wire rope, an axial mounting hole and a connecting surface connecting the two. A spiral rope groove is arranged on the cylindrical surface. A convex block is arranged on the connecting surface close to the mounting hole. The convex block has a conical surface, and a bolt hole is arranged on the conical surface. The cylindrical surface has edges at both ends. When the flat wheel body rotates rapidly, the steel wire rope is also rapidly retracted and placed. If there is no edge, the wire rope will break away from the flat wheel body and cause garage door failure.
One edge of the cylindrical surface is provided with a rope groove for placing the steel wire rope, and the inner side of the other edge is provided with a groove in the direction of the bolt hole on the convex block. One edge of the cylindrical surface is provided with a rope groove for placing the steel wire rope, which can prevent the steel wire rope from separating from the flat wheel body and facilitate the steel wire rope winding to the cylindrical surface; a groove is arranged on the inner side of the other edge of the cylindrical surface towards the bolt hole on the convex block, which can facilitate the bolt to rotate into the bolt hole on the cone surface of the convex block, because if there is no such groove, the bolt may be due to its length The problem cannot be turned into the bolt hole well. The connecting surface is also provided with a reinforcing rib. Due to the large volume of the garage door, the flat wheel body bears a large force, so the connecting surface is provided with a reinforcing rib, which can strengthen the structure of the flat wheel body. This door has the advantages of light weight, long service life, low cost, good manufacturing environment and less pollution. The connecting surface is provided with a bump near the installation hole, and the convex block has a conical surface, and a bolt hole is set on the cone surface, so that the body of the flat wheel is fixed more firmly and the safety is higher.
