Abstract:
1. A structure of a canopy comprising: a plurality of pillars erected on the ground; an end portion connection block fixed to an end portion of the pillar; a slide connection block capable of sliding along the pillar; a plurality of roof edge frames, each supporting an edge of a roof and including a first rod pivoting with respect to the end portion connection block of the pillar and a second rod pivoting with respect to the slide connection block, so that a center portion of the first and second rods pivots in X form capable of being hinge coupled; a plurality of roof center frames, each supporting a center portion of the roof and including a first rod pivoting with respect to the end portion connection block of the first rod of the roof edge frame and a second rod pivoting with respect to the end portion connection block of the second rod of the roof edge frame, so that a center portion of the first and second rods pivots in X form capable of being hinge coupled; a rod connection block connecting the roof edge frame and the roof center frame; an upper head connection block pivoting with respect to the first rod of each of the roof center frames to form an outer top end of the roof; a lower head connection block pivoting with respect to the second rod of each of the roof center frames to form an inner top end of the roof; a connection block including a corner reinforcement bar capable of being hinge coupled between the end portion connection block and the upper head connection block to reinforce a corner formed to face the center of the roof; and a roof cloth covering the roof edge frame and the roof center frame, wherein the slide connection block comprises: a main body which is an injection mold block where a cylindrical rail is formed on the bottom surface; a slide key lever which is a column type injection block capable of sliding by being inserted in the rail of the main body and having a leading end portion inserted in a through hole formed in the pillar when a user presses the slide key lever to slidingly advance; an elastic spring inserted around a leading end portion of the slide key lever and installed between the main body and the slide key lever to apply a restoring force in a direction to retreat the slide key lever; and a key lever fixing tool which is a latch caught by a hook groove formed in the slide key lever and inserted in a vertical hole formed in a fixing cap covering and fixing the slide key lever and lowered by its own weight so that, as the leading end portion is caught by the hook groove of the slide key lever, when the slide key lever is in an advanced state, the slide key lever is fixed.
