Abstract
The utility model discloses a special ruler for welding banister, comprising a bottom corner and a rotating corner which are mutually hinged; a sector level scale fixed on the bottom corner is arranged at the hinged part of the bottom corner and the rotating corner; and the upper part of the rotating corner is provided with a horizontal measuring device vertical to the measuring side of the rotating corner. In order to ensure that the bottom corner is parallel with the slope of a stair, a device for measuring level is arranged on the bottom corner. The angle of a groove can be confirmed very accurately through the rotation of the rotating corner and the cooperation of the horizontal measuring device; then accurate cutting on the groove of standing leg of the banister can be conveniently implemented through a groove cutter, which can be formed by one time and is convenient to be used.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of welding balustrade special ruler.
Background technology
In the welding of stainless steel balustrade, form groove angle between the station leg of handrail and the person in charge of handrail, the staff can only repeatedly polish to the groove of station leg by rule of thumb, just can make groove tight with being connected of handrail appropriate department.Neither one ruler easy to use is weighed in the prior art.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of welding balustrade special ruler easy to use.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of welding balustrade special ruler, be characterized in: comprise mutually hinged base angle and corner, be provided with the fan-shaped graduated scale that is fixed on the base angle in the hinged place of base angle and corner, be provided with the level measurement device vertical on the top of corner with the measurement limit of corner.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, be provided with the survey horizontal device on the base angle.
During use, at first with a straight section bar, as pipe or more smooth plate etc., be placed on the marking time of stair, the base angle of special ruler of the present utility model is placed on the above-mentioned section bar, the chi head upwards, pin joint rotates corner then down, and the bubble of the level measurement device on the corner is the level of state, this moment, the open angle at corner and base angle was exactly the lift angle of stair, the groove angle of the leg upper end of just standing.After the stationkeeping with corner and base angle, ruler is placed on the beveling machine, the base angle of ruler is close on the emery wheel of groove mechanism, then the angle block gauge adjustment of beveling machine is close to the corner of ruler, get final product bevel cut after the locking.Compared with prior art, by the rotation of corner, with cooperating of level measurement device, just can determine the angle of groove very accurately,, just can be very easily the groove of the station leg of handrail be cut accurately then by groove cutting machine, one-shot forming, convenient to use.
