[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0014] See Figure 1~2 , In the embodiment of the present invention, a special measuring instrument for architectural design includes a secondary ruler column 1, a clamping piece 2, a laser rangefinder 3, a main ruler column 4, a protractor 5, a chute 6, an angle indicating scale 7, a height Indicating scale 8, sight hole 9, aligning tip 10, tightening knob 11, adjusting bolt 12, length indicating scale 13, leveling ruler column 14 and spirit level 15, the side of the leveling ruler column 14 is provided with a length indicating scale on the lower side 13. The length indicator scale 13 is used to facilitate engineering length measurement. Both the left and right ends of the level column 14 are provided with adjusting bolts 12, and the upper right part of the level column 14 is provided with a level 15 which is adjusted by the level 15 The bolt 12 cooperates to adjust the levelness of the horizontal ruler column 14 to improve the accuracy of measurement. The left side of the leveler 15 is vertically provided with a main ruler column 4 on the upper part of the horizontal ruler column 14, and the middle part of the main ruler column 4 A secondary ruler column 1 is hingedly connected, and the hinge point of the secondary ruler column 1 and the main ruler column 4 is located in the middle of the secondary ruler column 1, and the front side of the right end of the secondary ruler column 1 is hinged with a clamping connection through a shaft 21 Part 2. The clamping part 2 is a cross-shaped structure. The clamping part 2 is used to measure the height of the building to be measured. A laser rangefinder 3 is provided on the back of the right end of the secondary ruler column 1. , The height of the long-distance object is measured by the laser rangefinder 3, and the specific height data is obtained through conversion. The left end of the secondary ruler column 1 is slidably connected to the middle chute of the protractor 5 through the tightening knob 11 In 6, the position of the secondary ruler column 1 can be fixed by tightening the knob 11. The left side of the tightening knob 11 is provided with an alignment tip 10 at the end of the secondary ruler column 1. The alignment tip 10 is convenient for reading Take the indicated value of the angle indicating scale 7. The right side of the tightening knob 11 is provided with a viewing hole 9 on the secondary ruler column 1. The viewing hole 9 is rectangular, and the center position of the viewing hole 9 is the same as that of the secondary ruler column 1. A reference line (not shown) is provided in parallel, and the reference line on the sight hole 9 is convenient to read the indicated value of the height indication scale 8. The protractor 5 is vertically located on the left side of the main ruler column 4, and the protractor 5 The top is connected to the main ruler column 4, the bottom of the protractor 5 is connected to the upper part of the horizontal ruler column 14, the middle position of the protractor 5 is provided with a chute 6, and the arc radius of the chute 6 is the auxiliary ruler column 1. The angle indicator scale 7 is provided on the outer ring of the protractor 5, the height indicator scale 8 is provided on the inner ring of the protractor 5, the position of the angle indicator scale 7 and the height indicator scale 8 Correspondingly, after calibration, mark the height of the right end of the sub-ruler column 1 at each angle position of the protractor 5, and then the project height can be measured.
[0015] The working principle of the present invention is: after the instrument is calibrated, the length can be measured by the length indicating scale 13 on the lower side of the horizontal ruler column 14, and the angle can be measured by the angle indicating scale 7 of the outer ring of the protractor 5, and by rotating the auxiliary ruler column 1. , Clamp the rotatable clip 2 to the building design of the height to be measured, and then lock it by tightening the knob 11, and the height indicated by the height indication scale 8 can be read through the reference line in the sight hole 9 The value is the building height. You can read the angle value indicated by the angle indicator scale 7 by aligning the tip 10 with the assistance. When the building height exceeds the measurement range, turn on the laser rangefinder 3 and rotate the auxiliary ruler column 1. , Make the laser rangefinder 3 point to the top of the building, and lock the secondary ruler column 1 by tightening the knob 11. The value read by the laser rangefinder 3 plus the length of the secondary ruler column 1 itself, and the secondary ruler The angle of the rotation of column 1 can be used to obtain the height of the building by the law of sine in the triangle. In addition, adjusting bolts 12 are set at both ends of the level column 14 and a spirit level is set on the upper right side of the level column 14 15. The levelness of the leveling rod 14 can be adjusted to make the height measurement more accurate.
[0016] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended to fall within the claims. All changes within the meaning and scope of equivalent elements of are included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
[0017] In addition, it should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for clarity, and those skilled in the art should consider the specification as a whole The technical solutions in the embodiments can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
