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.

　　一种重量轻、使用寿命长、成本较低、基本无污染的车库门用平轮。这种车库门用平轮，包括平轮本体，平轮本体具有绕有钢丝绳的圆柱面、轴向的安装孔以及连接两者之间的连接面，圆柱面上具有螺旋形绳槽，连接面上靠近安装孔处设有凸块，凸块具有锥面，其锥面上开设有螺栓孔。圆柱面两端具有边缘。平轮本体在快速转动中，钢丝绳也在快速收、放，如果没有边缘，钢丝绳会脱离平轮本体而导致车库门出现故障。

　　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.

　　圆柱面的一个边缘上开设有放置钢丝绳的绳槽，另一个边缘内侧向着凸块上螺栓孔的方向开设有凹槽。圆柱面的一个边缘上开设有放置钢丝绳的绳槽，可以防止钢丝绳脱离平轮本体，也可以方便钢丝绳绕到圆柱面上；圆柱面的另一个边缘内侧向着凸块上螺栓孔的方向开设有凹槽，可以方便螺栓转动到凸块锥面的螺栓孔内，因为如果没有这个凹槽，螺栓可能由于长度问题而无法很好地转入螺栓孔。连接面上还设有加强筋。由于车库门的体积较大，平轮本体承受的力较大，所以连接面上设有加强筋，可以强化平轮本体的结构。此门的优势比铁质平轮重量轻、使用寿命长、成本低了，制作环境好了，污染小了，连接面上靠近安装孔处设有凸块，凸块具有锥面，其锥面上开设有螺栓孔，这样固定平轮本体更牢固，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.
