It also supports digital data storage and integration, laying the foundation for the informatization of real estate management. Due to its portability and high accuracy, this rangefinder has become a core tool in land surveying.

[0003] A rangefinder for real estate surveying is a high-precision measuring device based on laser technology. It uses the laser time-of-flight or phase difference principle to quickly and accurately measure distances, angles, and areas. Its structure includes core components such as a laser transmitter, receiver, processor, measurement optical system, and data interface. It features high portability, diverse functions, and ease of operation. It is widely used in areas such as land title confirmation, building area and height measurement, and terrain data collection. It can not only accurately obtain data such as land boundaries, building outlines, and elevation differences, but can also be integrated into geographic information systems (GIS), providing efficient technical support for real estate management, planning, and judicial assessments.

[0004] However, existing real estate surveying and mapping equipment still has some shortcomings. For one thing, the laser transmitter lens is susceptible to contaminants such as dust, sand, and rain during long-term outdoor use, causing surface contamination. Frequent and manual cleaning is required, increasing maintenance costs. Improper lens cleaning can also damage the lens, shortening the equipment's lifespan. Furthermore, laser receivers are often affected by environmental factors such as strong and scattered light. This can reduce signal reception stability and measurement accuracy, especially on sunny days or in areas with severe light pollution.

[0005] In view of the above problems, a rangefinder for real estate surveying and mapping is proposed to solve the above problems. Utility Model Content

[0006] In order to make up for the above shortcomings, the utility model provides a rangefinder for real estate surveying and mapping, which aims to solve the problems of inconvenience in cleaning the lens after use and interference of the laser receiver by strong light in the existing equipment.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical solution: a rangefinder for real estate surveying and mapping, comprising a rangefinder body, an observation lens disposed at one end of the rangefinder body, a laser emitter and a laser receiver disposed at the other end of the rangefinder body, a display screen disposed on a side wall of the rangefinder body, and a cleaning mechanism and an anti-interference component disposed at the ends of the laser emitter and the laser receiver away from the rangefinder body, respectively;

[0008] The cleaning mechanism comprises a lens frame, a fixing component is arranged inside the lens frame, and a rotating handle is rotatably connected to the middle part of the lens frame.

[0011] As a further description of the above technical solution:

[0012] The outer side of the cleaning wet cotton towel is inserted into the interior of the card slot and abuts against the inner wall of the lens frame.

[0013] As a further description of the above technical solution:

[0014] An arc-shaped silicone convex plate is provided inside the annular frame, the end of the rotating handle abuts against the convex part of the arc-shaped silicone convex plate, and the concave part of the arc-shaped silicone convex plate abuts against the outer side of the cleaning wet cotton towel.

[0015] As a further description of the above technical solution:

[0016] An internal thread is provided on the inner side of the lens frame, the lens frame is threadedly connected to the laser emitter, and the cleaning wet cotton towel abuts against the lens in the laser emitter.

[0023] The utility model has the following beneficial effects:

[0024] 1. In this utility model, a protective cover with a wet cotton wipe cleaning function is installed outside the laser transmitter lens. After the equipment test is completed, the rotating handle can be turned to control the rotation of the ring frame within the lens frame. Under the action of the curved silicone convex plate, the cleaning wet cotton wipe clamped in the ring frame tightly contacts the lens inside the laser transmitter, thereby removing dust and dirt from the lens. The cleaned wet cotton wipe can then be pulled out. This not only effectively protects the lens from external contaminants such as dust and sand, but also enables automatic cleaning at any time, avoiding measurement errors caused by lens contamination. In addition, the replaceable design of the wet cotton wipe improves the maintainability of the equipment, reduces damage caused by improper lens cleaning, thereby extending the equipment life and reducing maintenance costs.

[0025] 2. This utility model incorporates a honeycomb-shaped light shielding tube on the exterior of the laser receiver, effectively blocking strong external light interference. This is particularly true in outdoor environments with strong or scattered light. While blocking scattered light, it allows the laser to accurately enter the receiver, significantly improving the stability of laser signal reception and measurement accuracy while also reducing the weight of the light shield itself. The honeycomb light shielding tube design improves the device's measurement accuracy and adapts to complex lighting environments, ensuring consistently accurate and reliable measurement results in diverse operating scenarios.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 4The present invention provides an embodiment of a rangefinder for real estate surveying and mapping, comprising a rangefinder body 1. An observation lens 2 is disposed at one end of the rangefinder body 1, and a laser emitter 4 and a laser receiver 5 are disposed at the other end, for emitting and receiving laser light. A display screen 3 is disposed on the sidewall of the rangefinder body 1 for displaying real-time measurement data and device status, facilitating operator review and adjustment. The display screen 3 can also transmit data to other devices via a built-in transmission chip. A cleaning mechanism 6 is disposed at the end of the laser emitter 4, distal from the rangefinder body 1, to ensure the lens surface of the laser emitter 4 remains clean, thereby improving measurement accuracy. The cleaning mechanism 6 comprises a lens frame 601, which is threadedly connected to the laser emitter 4 via internal threads for easy installation and removal. A fixing assembly is disposed within the lens frame 601 for securing the cleaning assembly. The core component of the cleaning mechanism is an annular frame 602. The central portion of the annular frame 602 is connected to a rotating handle 603 via a rotating shaft. Rotating the handle 603 rotates the annular frame 602, completing the cleaning function. The fixed assembly comprises a ring-shaped frame 602, within which are mounted multiple wet cleaning wipes 605. These wipes are evenly distributed along the frame's interior. One end of each wipe is secured to the inner wall of the frame 602 via multiple slots 604, while the other end securely adheres to the lens surface of the laser emitter 4, achieving effective cleaning. To ensure the stability of the wipes and the cleanliness of the lens surface during cleaning, a curved silicone protrusion 607 is designed within the frame 602. Its raised portion abuts the end of the rotating handle 603, while its recessed portion securely adheres to the wipes 605. This structural design allows the curved silicone protrusion 607 to drive the wipes to wipe the lens surface as the handle 603 rotates, achieving efficient lens cleaning. Furthermore, a support rod 606 is fixedly attached to the interior of the frame 602, further enhancing its structural strength and stability. The support rod 606 also serves as a connection fulcrum for the rotating handle 603, making it more stable during operation. The cleaning wet cotton towel 605 is designed to be replaceable. When the wet cotton towel is worn or loses its cleaning ability, it can be quickly replaced through the card slot 604, which is easy to operate and practical.

[0035] Reference Figure 1 and Figure 5, the laser transmitter 4 is used to emit laser, and the laser receiver 5 is used to receive the reflected laser signal and perform data processing. In order to enhance the anti-interference ability of the equipment, an anti-interference component 7 is installed at the end of the laser receiver 5 away from the rangefinder body 1 to reduce the interference of external light on laser reception; the anti-interference component 7 includes a honeycomb light-shielding tube 701, and the honeycomb light-shielding tube 701 is fixedly connected to the laser receiver 5 through a snap-on structure, which is easy to install and highly stable. The interior of the honeycomb light-shielding tube 701 is designed with a plurality of honeycomb holes 702. These holes are arranged in a regular pattern, and their structure is similar to a honeycomb, which can effectively weaken the interference of multi-directional scattered light while allowing the laser signal to pass accurately. The layout of the honeycomb holes 702 has been precisely calculated, which not only ensures the light transmission efficiency but also enhances the anti-interference effect. In order to further improve the stability and signal quality of laser reception, a laser through hole 703 is also opened in the middle of the honeycomb light-shielding tube 701. The diameter of the laser through hole 703 matches the photosensitive area of ​​the laser receiver 5, which is used to accurately receive the laser signal and prevent external non-target light from entering the receiver, thereby ensuring the accuracy of the measurement data.

[0036] Working principle: When measuring distance, the laser transmitter 4 emits a laser signal, which is reflected back to the laser receiver 5 after reaching the target. The laser receiver 5 captures the reflected signal and calculates the distance data through the built-in data processing chip, and displays the measurement results in real time on the display screen 3 on the side wall of the rangefinder body 1. To ensure the accuracy of the measurement, the laser transmitter 4 is equipped with a cleaning mechanism 6. When there is stain on the lens surface, the handle 603 is turned to drive the annular frame 602 to rotate, driving the cleaning wet cotton towel 605 to clean the lens surface, ensuring that the lens always remains clean. In addition, to enhance the anti-interference ability, the laser receiver 5 is equipped with an anti-interference component 7. Its honeycomb light shielding tube 701 uses the honeycomb holes 702 to weaken the interference of multi-directional scattered light, and accurately receives the target signal through the laser through-hole 703, thereby improving the measurement accuracy and adapting to complex environments. Through the collaboration of the cleaning mechanism 6 and the anti-interference component 7, the equipment achieves efficient and accurate real estate surveying and mapping.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
