Photovoltaic welding strip winding reel with protection structure

A photovoltaic welding strip winding reel with a protection structure comprises an upper cover plate, a containing plate is arranged under the upper cover plate, grooves are formed in the positions, close to the edges of the two sides, of the inner side walls of the upper cover plate and the containing plate, a through hole is formed in the side wall of one end of the containing plate in a penetrating mode, inserting grooves are formed in the middles of the side walls of the tops of the two ends of the containing plate, and the upper cover plate is fixedly connected with an inserting piece. The utility model has the following advantages: the wire coil can be locked by the upper cover plate and the containing plate, so that a welding strip wound on the wire coil is not in direct contact with the outside; the inserting columns are inserted into the inserting grooves, and the locking blocks are inserted into the locking grooves formed in the side walls of the inserting columns, so that the upper cover plate and
