The present invention relates to a roll-type insect-proof net device comprising an upper frame including the open bottom, a bolt joining unit formed inside an internal space unit, and a pair of upper joining units formed inside the space unit and including an upper joining hole; a rotary roller; a shaft unit; a first lateral plate; a second lateral plate; a lower frame; a lower lateral plate; a locking unit; an operation unit; a lateral frame; and an insect-proof net. The upper part of the insect-proof net is joined to a fitting unit formed on a roller of the rotary roller. The lower part of the insect-proof net is joined to an insect-proof net groove formed on an insect-proof net fixing unit of the lower frame and a sub insect-proof net groove formed on the lower lateral plate. Both sides of the insect-proof net are positioned inside the lateral frame to adhere closely to a lateral brush. The present invention is easily joined and fixed to the upper frame through first and second fixed plates, the shaft unit, and the first and second lateral plates formed on the rotary roller. A spring of the shaft unit is joined to a shaft and the shaft is firmly fixed to the first lateral plate at the same time so that the spring is regularly rotated without distortion. Accordingly, the present invention obtains an effect of winding or unwinding the insect-proof net to be flat without distortion. |
