Description

A kind of hand is drawn large-scale circle device

[technical field]

The present invention relates to a kind of circle instrument, especially relate to a kind of hand and draw large-scale circle device.

[background technology]

Known, at stone face or metallic plate or plank stroke circle, small-sized useful marking gauge is also referred to as plans or compasses are realized, but surpass 20 centimeters even during several meters circle, can only use the pilot pin in middle part, driving the peripheral portion marking-off pin by flexible cord rules, the accuracy of this mode is lower, the circular error that draws is sometimes above several centimeters, so having found out, some workmans utilize ruler to draw a plurality of points " the employing connection segment is drawn method ", then utilize line to connect, the circle that draws so is not to justify very much, and does not also have on the market the line tool of large-scale circle.

[summary of the invention]

In order to overcome the deficiency in the background technology, the present invention discloses a kind of hand and draws large-scale circle device, when stone face or metallic plate upper drawing circle circle, utilizes the interior positioning pipe of rotation seat as the center of circle, utilize the machine leader traction of barrel one side, the pen hair just can draw the circle of standard.

For achieving the above object, the present invention adopts following technical scheme:

A kind of hand is drawn large-scale circle device, comprise rotation seat, bearing, barrel, 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 to center, rotation seat lower end in the upper 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.

Because adopt aforesaid technical scheme, the present invention has following beneficial effect:

Hand of the present invention is drawn large-scale circle device, when the larger stone face of area or metallic plate draw the standard circle, according to designing requirement, utilize ruler to 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, then use the hand-held rotation of machine leader traction of barrel one side, paintbrush just can mark required circle under workman's operation; When the present invention has depression or projection at stone face or metallic plate, regulate the circle that the paintbrush that is articulated and connected of pole socket and length adjustment bar draws standard on also can on-plane surface.
