Description

Technical Field

[0001] This utility model relates to a surveying device for building construction, belonging to the field of surveying technology. Background Technology

[0002] Construction surveying equipment is a general term for a class of precision equipment used throughout the entire life cycle of a construction project for measuring, setting out, and monitoring the spatial position and shape. Its core purpose is to accurately mark the plan position, shape, and elevation of buildings or structures on the design drawings onto the actual site, monitor deformations during construction, ensure that the project is constructed strictly according to the drawings, and guarantee quality and safety.

[0003] Most traditional rangefinders require single-point, step-by-step measurements when measuring room width. They need to first measure the distance A from one end to the wall, then move the instrument to the other end (or turn around) to measure the distance B to the other wall, and finally manually add A and B to the instrument's own length (or estimated offset), which can easily lead to cumulative errors.

[0004] Traditional rangefinders can only measure distances in the horizontal direction. To measure height, the instrument needs to be manually placed on its side or other support points need to be found, which makes it difficult to ensure verticality and is inconvenient to operate. There is a problem that a single device cannot simultaneously provide high-precision horizontal and vertical measurements.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a surveying device for building construction, which can solve the problems of cumbersome operation and low efficiency, improve the accuracy and reliability of measurement results, and also solve the problem that a single device cannot simultaneously achieve high-precision horizontal and vertical measurements.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A surveying device for building construction includes a handle, one end of which is hinged to one end of a folding arm. An angle adjustment head and a laser rangefinder are sequentially mounted on the other end of the folding arm. The laser rangefinder has symmetrically arranged laser emitters at both ends, which emit lasers synchronously in opposite directions. The handle has a bulge with a hollow internal structure. A display screen is embedded in the bulge, and a battery and controller are installed inside the bulge.

[0008] Furthermore, the folding arm consists of two hinged arms.

[0009] Furthermore, a spirit level is installed on the outside of the hinge between the folding arm and the grip.

[0010] Furthermore, the battery and controller are located on the back of the display screen.

[0011] Furthermore, the battery is electrically connected to the laser rangefinder, controller, and display screen, and the battery supplies power to all three.

[0012] Furthermore, the connecting wires between the battery and the laser rangefinder are threaded inside the folding arm.

[0013] Furthermore, the side of the display screen is equipped with two buttons arranged side by side, including a reset button and a start button.

[0014] Furthermore, a flip cover is provided on the outside of the location where the battery is installed.

[0015] Furthermore, the end of the grip away from the folding arm is provided with a connection hole, through which the grip is connected to the tripod.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: In this invention, two laser heads simultaneously emit lasers in opposite directions, allowing for a single measurement to directly obtain the distances L1 and L2 between the two ends, as well as the total distance L (L0+L1+L2), which are then displayed directly on the screen. This solves the problems of cumbersome operation and low efficiency.

[0017] Once the instrument is placed, two measurements are acquired synchronously based on the same reference point, eliminating reference errors caused by moving the instrument. The total distance calculation is completed automatically by the equipment, reducing human error.

[0018] The laser rangefinder can be rotated 90 degrees by adjusting the angle head, easily switching from measuring width to measuring height. When used with a spirit level, it can ensure the vertical or horizontal accuracy of the measurement.

[0019] Featuring both handheld and tripod modes, it boasts an ergonomically designed grip for easy handling. A standard connection hole is pre-drilled at the end of the grip for quick and easy mounting onto a tripod, enabling stable measurements. The measurement mode switching is flexible.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown in the figure, this utility model provides a surveying device for building construction, including a handle 1, one end of which is hinged to one end of a folding arm 2, and an angle adjustment head 3 and a laser rangefinder 4 are sequentially installed on the other end of the folding arm 2.

[0025] The folding arm 2 consists of two hinged arms.

[0026] The laser rangefinder 4 can rotate 90 degrees under the action of the angle adjustment head 3. The laser rangefinder 4 can be set in either the horizontal or vertical direction.

[0027] The laser rangefinder 4 has symmetrically arranged laser emitters 5 at both ends, and the two laser emitters 5 emit lasers synchronously in opposite directions.

[0028] A spirit level 7 is installed on the outside of the hinge joint between the folding arm 2 and the handle 1. The operator can manually adjust the angle of the handle 1 by observing the spirit level 7 so that the laser rangefinder 4 is in a horizontal or vertical state.

[0029] The grip 1 is provided with an enlarged part 8, the interior of which is hollow. A display screen 9 is embedded in the enlarged part 8, and a storage battery 10 and a controller 11 are installed inside the enlarged part 8. The storage battery 10 and the controller 11 are located on the back of the display screen 9.

[0030] The battery 10 is electrically connected to the laser rangefinder 4, the controller 11, and the display screen 9, and the battery 10 supplies power to all three. The connecting wire between the battery 10 and the laser rangefinder 4 is run inside the folding arm 2.

[0031] The side of the display screen 9 is equipped with two buttons 12 arranged side by side, including a reset button and a start button.

[0032] The battery 10 is provided with a flip cover 13 on the outside of the installation location, which facilitates the replacement of the battery 10.

[0033] The handle 1 has a connecting hole 6 at its end away from the folding arm 2. The handle 1 is connected to the tripod through the connecting hole 6, and the tripod can provide support for the entire device. The device can be used for handheld distance measurement or for distance measurement after being fixed to the frame.

[0034] The specific working principle of this utility model is as follows: Assuming the distance between the two laser emitters is a fixed value L0, the distances measured by the two laser emitters in opposite directions are L1 and L2, respectively, which gives the measured distance L, where L = L0 + L1 + L2, and L is directly displayed on the screen.

[0035] This utility model has two measurement modes: handheld and rack-mounted. Handheld mode: Place the device in room one, with the two laser emitters facing the side walls respectively. Press the "Start" button, and the display will simultaneously show the distances to the left and right walls, as well as the overall distance. Rack mode: If more stable or continuous measurements are required, attach the connection hole at the end of the handle to a tripod, secure the entire unit, and then perform the measurement.

[0036] This invention allows the laser rangefinder to be rotated 90 degrees via an angle adjustment head, switching from horizontal to vertical measurement mode. With the two laser emitters pointed at the ceiling and the ground respectively, the distance to the ground and the distance to the ceiling can be measured.
