Abstract
The utility model discloses height measuring equipment for construction site, which includes a vertical scale and a laser emitter, wherein the laser emitter is arranged at the rear part of the vertical scale; the vertical scale is a scale with a pin, and the pin is inserted into the ground surface; and the laser emitter is mounted on a rotating device on the ground, so that the laser emitter can rotate around the rotating device. The height measuring equipment utilizes the laser emitter and the scale and the principle that the similar edges of the similar triangles are proportional, so as to measure the height simply and conveniently. The height measuring equipment has simple structure and low cost, is convenient to use, and is very practical.
Description
Technical field:
The utility model relates to a kind of device of measuring height, and is particularly related to a kind of building ground and uses height measuring equipment.
Background technology:
On the building ground, often need measure the height of some buildings or object roughly, because these object heights have exceeded people's height, and can't fall and directly measure with tape measure on the ground.Though can accomplish highly then and measure by ladder, this needs a lot of costs again, and wastes time and energy.Because a lot of occasions on the building ground are not the too accurate measurement data of requirement, therefore there is no need the exact instrument that the flower high price removes to purchase a special measuring height yet.
If can design a kind of easy measurement mechanism, i.e. operation easily, the cost that need not cost a lot of money again, and can reach the purpose of the height of measuring some buildings or object roughly, just can address the above problem.
The utility model content:
The purpose of the utility model is to provide a kind of building ground to use height measuring equipment, is an a kind of generating laser and scale of utilizing, and with the proportional principle in the similar limit of similar triangle, comes the easy height measuring equipment of measuring height.
To achieve these goals, the technical scheme of the utility model is:
Height measuring equipment is used in the building ground, it is characterized in that, comprises a vertical scale, a generating laser, and said generating laser is placed on the rear portion of said vertical scale.
Said vertical scale is one to have the scale of pin, the said pin into face of land of planting.
Said generating laser is installed on the ground whirligig, and generating laser can be rotated around said whirligig.
Beneficial effect: height measuring equipment is used in the utility model building ground, is an a kind of generating laser and scale of utilizing, and with the proportional principle in the similar limit of similar triangle, comes the easy height measuring device of measuring height; The utility model is simple in structure, and cost is low, and is easy to use, very practical.
Description of drawings:
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model building ground with height measuring equipment.
Embodiment:
Embodiment to the utility model elaborates below in conjunction with accompanying drawing: present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
Embodiment
With reference to figure 1, be example with the height in the compartment of measuring a certain automobile, comprise generating laser 1, vertically scale 2, automobile bodies 3 among the figure, generating laser 1 is placed on the rear portion of vertical scale 2.Open the switch of generating laser 1; Make generating laser 1 send laser, this laser sees through vertical scale 2 and shines on the automobile bodies 3 rotary laser transmitter 1; Make laser radiation arrive the top of automobile bodies 3, this moment, laser passed the height h on the vertical scale 2 to meter down.
The distance of using tape measure to go out from generating laser 1 to vertical scale 2 again is a, and the distance from vertical scale 2 to automobile bodies 3 is b.If the height of automobile bodies 3 is x, then, draw proportionate relationship: a: h=(a+b): x, x=(a+b) h/a like this according to the proportional principle in the similar limit of similar triangle.Because the value of a, b, h is known, the value of x just can be obtained.
Height measuring equipment is used in the utility model building ground, is an a kind of generating laser and scale of utilizing, and with the proportional principle in the similar limit of similar triangle, comes the easy height measuring device of measuring height; The utility model is simple in structure, and cost is low, and is easy to use, very practical.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
