Description

Technical Field

[0001] This invention relates to the field of engineering instrument technology, specifically to a multifunctional laser rangefinder. Background Technology

[0002] A laser rangefinder is an instrument that measures the distance to a target by modulating a specific parameter of a laser beam. The measuring range of laser rangefinders is 3.5 to 5000 meters. Based on the ranging method, they are divided into phase-based rangefinders and pulse-based rangefinders. A pulse-based laser rangefinder emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the observer to the target. A phase-based laser rangefinder measures distance by detecting the phase difference between the emitted and reflected light as they propagate through space. Laser rangefinders are characterized by their light weight, small size, simple operation, high speed, and accuracy.

[0003] In the present technology, laser rangefinders are often used in engineering projects, such as civil engineering or decoration. Due to the complex environment in construction projects, construction workers often have many tasks and need many tools. Therefore, it is inconvenient to carry too many measuring tools and they are easy to lose. Summary of the Invention

[0004] This invention proposes a multifunctional laser rangefinder. This solution integrates a laser rangefinder and a line projector into one unit, and the two functions do not interfere with each other. This solves the problem in the prior art that two devices are required when measuring distance and level. Applying this solution can increase the convenience for users.

[0005] The technical solution of the present invention is as follows:

[0006] This invention relates to a multifunctional laser rangefinder, comprising a housing and a power supply for the multifunctional laser rangefinder. A mounting plate is fixedly disposed inside the housing. An adjacent laser emitter and laser receiver are disposed at one end of the housing. A control board for the multifunctional laser rangefinder is fixedly mounted on the mounting plate. The invention is characterized by further comprising a horizontal laser emitter hole and a vertical laser emitter hole disposed adjacent to each other at the other end of the housing. The horizontal laser emitter hole and the vertical laser emitter hole are signal connected to the control board.

[0007] As a further optimization of this solution, the power supply is charged via an external power source connected to a USB interface, and the USB interface is electrically connected to the control board.

[0008] As a further optimization of this solution, the upper side of the multi-functional laser rangefinder is equipped with a display screen and an adjustment switch, which are electrically connected to the control board.

[0009] As a further optimization of this solution, the housing includes an outer shell and an inner shell. The outer shell is a long cylindrical structure with a first opening at its bottom. The outer shell is fitted over the outer side of the inner shell. The upper side of the inner shell has a second opening and a third opening. When the outer shell and the inner shell are normally installed, the second opening and the third opening are contained within the first opening. The second opening has a display screen embedded in it and an adjustment switch also embedded in it.

[0010] As a further optimization of this solution, the control board is mounted on a mounting plate, which has a display port and a switch port. The display port is fitted with the outer protruding frame of the display screen, and the switch port is fitted with a protruding adjustment switch.

[0013] As a further optimization of this solution, the USB interface is a TYPE-C interface.

[0014] The working principle and beneficial effects of this invention are as follows:

[0015] In this application, a laser beam can be emitted from a laser emission source, and after reaching the point to be measured, the beam is returned to the laser receiver, thereby realizing the measurement of the distance to the target point by laser. When it is necessary to measure the horizontal or vertical degree of the target object, the horizontal and vertical laser emission holes on the other end of the product are opened. First, the multi-functional laser rangefinder is placed on a horizontal frame and adjusted to be horizontal. The specific accuracy needs to be determined according to the site conditions and worker experience. Then, the laser will project horizontal and vertical lines, with the horizontal line being horizontal to the ground and the vertical line being vertical to the ground. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] As per the instruction manual Figure 1 As shown, a multifunctional laser rangefinder includes a housing and a power supply for the rangefinder. A mounting plate is fixedly installed inside the housing. An adjacent laser emitter and receiver are located at one end of the housing. A control board for the multifunctional laser rangefinder is fixedly installed on the mounting plate. The rangefinder is characterized by further including a horizontal laser emitter hole and a vertical laser emitter hole located adjacent to each other at the other end of the housing. These horizontal and vertical laser emitter holes are signal-connected to the control board. In this application, a laser beam is emitted from the laser emitter, and after reaching the point to be measured, the beam returns to the laser receiver, thereby achieving the measurement of the distance to the target point via laser. When it is necessary to measure the horizontal or vertical orientation of the target object, the horizontal and vertical laser emitter holes at the other end of the product are opened. First, the multifunctional laser rangefinder is placed on a horizontal frame and adjusted to be horizontal. The specific accuracy needs to be determined based on the site conditions and worker experience. Then, the laser will project horizontal and vertical lines, with the horizontal line horizontal to the ground and the vertical line perpendicular to the ground.

[0029] As per the instruction manual Figure 2 and 4As shown, the power supply is connected to an external power source via a USB interface for charging, and the USB interface is electrically connected to the control board. The USB interface is located on the side of the housing and is a Type-C interface. The type of USB interface can be selected according to the battery model, etc.

[0030] As per the instruction manual Figure 1 , 3 As shown in Figure 5, the upper side of this multifunctional laser rangefinder is equipped with a display screen and an adjustment switch, which are electrically connected to the control board. The control board is a circuit board with the circuitry required for the laser rangefinder and line projector soldered on to support the control system. The control system can utilize existing commercial technology to enable the normal operation of the laser rangefinder and line projector.

[0031] As per the instruction manual Figure 3-9 As shown, the housing includes an outer shell and an inner shell. The outer shell is a long, cylindrical structure with a first opening at its bottom. The outer shell fits over the outer side of the inner shell. The upper side of the inner shell has a second opening and a third opening. When the outer shell and inner shell are normally installed, the second and third openings are contained within the first opening. The second opening houses a display screen and an adjustment switch. This design of the inner and outer shells ensures a good appearance during production. The inner shell facilitates the installation of the control board. During production, the inner shell requires the installation of both the mounting plate and the control board, resulting in a relatively complex internal structure. The outer shell, however, has a simpler structure and is easier to manufacture. When producing products with different appearances, only different molds need to be made for the outer shell, saving production costs and increasing the stability of the instrument, thus providing protection. The control board is mounted on the mounting plate, which has a display port and a switch port. The display port is fitted with a raised frame for the display screen, and the switch port is fitted with a raised adjustment switch.

[0032] As per the instruction manual Figure 2 and 3 As shown, a mounting groove is formed in the middle of the side of the housing, and a mounting component is disposed in the mounting groove. The mounting component is used to place the bracket, which can fix and level the projector.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
