The utility model relates to a remote control anti-theft garage door of fiber glass reinforced plastics. A door body is composed of the connection of two parts, an upper door body is fixed on a wall, a lower door body is hinged with the upper door body, one end of a steel wire of a pulling and elevating piece is connected with the lower door body, and the other end is coiled on a transmission shaft with a helical wheel groove which is the structure of a variable diameter. A helical groove with a major diameter is spirally and around fixed on the transmission shaft with a correspondingly minor shaft diameter, and the transmission shaft is connected with a main shaft of a motor. The lower part of the lower door body is provided with an electronic lock and a drive motor, and the electronic lock is controlled by a remote control device of a circuit. The utility model can improve the existing garage door; hence, cost is reduced. The utility model has the characteristics that the function of circuit protection is complete, operation is safe and reliable, mechanical structure is devised reasonably and fault which is likely to generate can be reduced; hence, the performance of a product is stable.
