Spray gun adjustable in nozzle scope and special for building coating

Abstract

The invention discloses a spray gun adjustable in the nozzle scope and special for building coating. A fixing lantern ring is arranged at the outer end of a coating main spray pipe, and the coating main spray pipe is in a single tube shape or a multi-tubular prunus mume shape, so that the overall spraying scope is much wider and more uniform; the spray gun is practical, the inner and outer sides of elastic wrapping bands and rubber clamping strips are all fixed to the middle segments of the fixing lantern ring and coating main spray pipe respectively, and the rubber clamping strips are radially arranged on the six elastic wrapping bands on the basis of the coating main spray pipe, so that the elastic wrapping bands and the rubber clamping strips ensure the sealing performance during adjustment of the spraying scope. Four fixing blocks and four second bearing blocks are staggered with each other on the basis of the coating main spray pipe and fixedly connected with the coating main spray pipe, adjusting bolts penetrate through threaded connection holes to be fixedly connected with inner rings of fixing bearings to make multi-angular spraying scope adjustment of the coating main spray pipe much easier, and the operation is fast.
