Abstract

The utility model discloses a manual-type large-scale circle drawing device, and relates to a circle tool. A pipe body (16) is arranged at the upper portion of a rotating base (1). A diameter-expanding section (12) is arranged at the lower portion of the pipe body (16). A bearing inner ring (1) of a bearing is connected with the pipe body (16) in a sleeved mode. A sleeve (14) is sleeved on a bearing outer ring (13). An adjusting rod base (2) arranged on the outer wall of one side of the sleeve (14) is hinged to one end of a length adjusting rod (3) through a shaft (17). The other end of the length adjusting rod (3) is connected with one end of a loop bar (7) in an inserted mode and locked by a positioning screw (4). The other end of the loop bar (7) is provided with a charging barrel (8). A painting brush (9) is arranged at the lower portion of the charging barrel (8). A traction piece (6) is arranged on the charging barrel (8).

For realizing above-mentioned utility model purpose, the utility model adopts following technical scheme:

A kind of hand is drawn large-scale circle device, comprise rotation seat, bearing, length adjustment bar, barrel and paintbrush, the top of described rotation seat is provided with body, the body bottom is provided with extension diameter section, the bearing inner race socket body of bearing, jacket casing is on bearing outer ring, the adjusting pole socket that arranges at sleeve one side outer wall is by a be articulated and connected end of length adjustment bar of axle, other end grafting loop bar one end of length adjustment bar and locked by set screw, the loop bar other end is provided with barrel, be provided with paintbrush in the barrel bottom, described barrel is provided with machine leader.

Described hand is drawn large-scale circle device, is provided with the position observation hole of perforation at upper end to the center, rotation seat lower end of body, and the positioning pipe that is in lower central position, position observation hole is connected with position observation hole inwall by at least three connecting rods.

Described hand is drawn large-scale circle device, is provided with interior ring in upper cartridge, and described interior ring is pressed on the upper surface of bearing outer ring.

Described hand is drawn large-scale circle device, is provided with screw at loop bar, and set screw passes the other end of locking length adjustment bar behind the described screw.

Described hand is drawn large-scale circle device, is provided with lid in the barrel upper surface.

Described hand is drawn large-scale circle device, the pen mao center perpendicular to barrel in the paintbrush bottom that barrel arranges.

Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:

Hand described in the utility model is drawn large-scale circle device, when the bigger stone face of area or metallic plate draw the standard circle, according to designing requirement, utilize ruler draw A point, B point, utilize the corresponding required circle center A point of positioning pipe in the rotation seat centralized positioning peep hole, adjust length by length adjustment bar, loop bar, use the hand-held rotation of machine leader traction of barrel one side then, paintbrush just can mark required circle under workman's operation; When the utility model has depression or projection at stone face or metallic plate, regulate the paintbrush that is articulated and connected of pole socket and the length adjustment bar circle of standard that draws on also can on-plane surface.
