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.

　　一種重量輕、使用壽命長、成本較低、基本無污染的車庫門用平輪。這種車庫門用平輪，包括平輪本體，平輪本體具有繞有鋼絲繩的圓柱面、軸向的安裝孔以及連接兩者之間的連接面，圓柱面上具有螺旋形繩槽，連接面上靠近安裝孔處設有凸塊，凸塊具有錐面，其錐面上開設有螺栓孔。圓柱面兩端具有邊緣。平輪本體在快速轉動中，鋼絲繩也在快速收、放，如果沒有邊緣，鋼絲繩會脫離平輪本體而導致車庫門出現故障。

　　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.

　　圓柱面的一個邊緣上開設有放置鋼絲繩的繩槽，另一個邊緣內側向著凸塊上螺栓孔的方向開設有凹槽。圓柱面的一個邊緣上開設有放置鋼絲繩的繩槽，可以防止鋼絲繩脫離平輪本體，也可以方便鋼絲繩繞到圓柱面上；圓柱面的另一個邊緣內側向著凸塊上螺栓孔的方向開設有凹槽，可以方便螺栓轉動到凸塊錐面的螺栓孔內，因為如果沒有這個凹槽，螺栓可能由于長度問題而無法很好地轉入螺栓孔。連接面上還設有加強筋。由于車庫門的體積較大，平輪本體承受的力較大，所以連接面上設有加強筋，可以強化平輪本體的結構。此門的優勢比鐵質平輪重量輕、使用壽命長、成本低了，制作環境好了，污染小了，連接面上靠近安裝孔處設有凸塊，凸塊具有錐面，其錐面上開設有螺栓孔，這樣固定平輪本體更牢固，性能更高。

　　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.
