車庫門一般分為手動車庫門和自動車庫門，由於手動車庫門開、關麻煩，且容易壞，目前都使用自動車庫門。自動車庫門中使用更多的是卷簾車庫門，因為卷簾車庫門製作高度可達到9米 14米，製作寬度4米 12米，抗風能力達到11級。所以，卷簾車庫門的配件都需要具有較高的強度和韌性。例如卷簾車庫門的簾片采用高強度鋁合金雙(單)層擠壓成型。目前，車庫門用平輪是鐵質的，重量較重，使用壽命短，成本高，製作環境髒亂，對環境有一定的汙染性。
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.
