DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, an outdoor measuring device for engineering cost includes a base 1, a column 2, a dial 3, a fixed rod 4, a movable rod 5 and a laser rangefinder 6.

[0026] like Figure 1 , Figure 2 As shown, the base 1 is horizontally arranged on the ground, and a telescopic tripod 11 is arranged at the lower end of the base 1 for adjusting the levelness of the base 1. A universal wheel 12 is arranged at the lower end of the tripod 11 for conveniently controlling the movement of the base 1 on the ground. The column 2 is vertically arranged on the base 1, and the dial 3 is arranged in a fan shape and horizontally fixed to the upper end of the column 2.

[0027] like Figure 1 , Figure 2 As shown, the fixed rod 4 is fixedly arranged on the lower end surface of the scale plate 3 and is located at the bevel position on one side of the scale plate 3. The tail end of the movable rod 5 is rotatably connected to the top angle position of the upper end surface of the scale plate 3 and is located above the fixed rod 4. The laser rangefinder 6 is arranged at the ends of the fixed rod 4 and the movable rod 5.

[0028] like Figure 1 , Figure 2 As shown, the movable rod 5 is provided with an observation hole 51 arranged along the length direction thereof, and a circle of lighting lamps 52 is arranged on the inner wall of the observation hole 51 .

[0029] When the length of an outdoor building needs to be measured, the base 1 is placed on the ground and the tripod 11 is adjusted to adjust the levelness of the base 1. Then, a pair of laser rangefinders 6 are turned on, and the laser rangefinder 6 on the fixed rod 4 is aligned with one end of the building to be measured, and the distance at this time is recorded as a. Then, the movable rod 5 is controlled to rotate, and the laser rangefinder 6 on the movable rod 5 is aligned with the other end of the building to be measured, and the distance at this time is recorded as b.

[0030] At the same time, observe the vertical on the dial 3 through the observation hole 51, record the angle of rotation of the movable rod 5 as A, and finally calculate the length of the building to be measured according to the cosine theorem: c^2=a^2+b^2-2abCosA.

[0031] Therefore, by using two laser rangefinders 6 to measure the distance from the fixed point to the two ends of the position to be measured, and according to the angle on the dial 3, the sine theorem can be used to calculate the length of the position to be measured. The entire measurement process does not require workers to return many times, and they can measure multiple positions by standing in one place, making the measurement process more convenient and improving measurement efficiency.

[0032] like Figure 1 , Figure 2 As shown, the upper end of the column 2 is rotatably connected to a sleeve 7, and a locking mechanism 8 is provided on the sleeve 7 to fix it. The locking mechanism 8 includes a locking plate 81, which is arranged in an arc shape and is rotatably connected to the lower end outer wall of the sleeve 7 at a bulged position in the middle.

[0033] like Figure 1 , Figure 2 As shown, a torsion spring 82 is provided at the rotation position of the locking plate 81, and a locking hook 83 is provided at the lower end bent inwardly, a locking groove 84 is provided on the outer wall of the column 2 for the locking hook 83 to be embedded in, and a pressing plate 85 is provided at the upper end of the locking plate 81 extending vertically downward.

[0034] When the base 1 is fixed to the ground, if the laser rangefinder 6 on the fixing rod 4 cannot illuminate one end of the building to be measured, the pressing plate 85 is pressed close to the column 2, and the locking plate 81 is driven to flip, so that the locking plate 81 drives the locking hook 83 to disengage from the locking groove 84 on the column 2, and the rotation control of the sleeve 7 can be realized.

[0035] When the laser rangefinder 6 on the fixing rod 4 illuminates one end of the building to be measured, the pressure plate 85 is released. At this time, the locking plate 81 is controlled to flip under the action of the torsion spring 82, so that the locking hook 83 on the locking plate 81 is embedded in the locking groove 84 to achieve locking, thereby fixing the dial 3 to meet stable measurement.

[0036] like Figure 1 , Figure 2 As shown, the column 2 includes a bottom rod 21 and a top rod 22. The bottom rod 21 is fixed on the base 1. The top rod 22 is arranged at the upper end of the bottom rod 21 and is horizontally rotatably connected to the bottom rod 21. A fixing mechanism 9 for fixing the top rod 22 is arranged on the bottom rod 21.

[0037] like Figure 1 , Figure 2As shown, the fixing mechanism 9 includes a fixing tube 91, a retaining ring 92 and a spring 93. The fixing tube 91 is slidably connected to the bottom rod 21 and is used to be sleeved on the top rod 22. The retaining ring 92 is arranged on the outer wall of the bottom rod 21 and is located below the fixing tube 91. The spring 93 is sleeved on the outer wall of the bottom rod 21 and is located between the retaining ring 92 and the fixing tube 91.

[0038] When the height of an outdoor building needs to be measured, the base 1 is placed on the ground and the tripod 11 is adjusted to adjust the level of the base 1. Then the fixing tube 91 is pulled downward to separate the fixing tube 91 from the top rod 22, and then the top rod 22 is controlled to flip 90 degrees to change the dial 3 from a horizontal state to a vertical state.

[0039] Then adjust the position of the scale plate 3 so that the laser rangefinder 6 on the fixed rod 4 is aligned with one end of the building to be measured, and then control the movable rod 5 to rotate so that the laser rangefinder 6 on the movable rod 5 is aligned with the other end of the building to be measured.

[0040] At the same time, observe the vertical on the dial 3 through the observation hole 51, record the angle of rotation of the movable rod 5 as A, and finally calculate the height of the building to be measured according to the cosine theorem: c^2=a^2+b^2-2abCosA.

[0041] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
