Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, specifically to a surveying device that integrates ranging and image recording. Background Technology

[0002] In field operations of engineering surveying, geological mapping, and building construction, distance measurement and on-site image recording are two core fundamental tasks that directly affect the accuracy of operational data and the safety of project implementation. Existing technologies have integrated distance measurement and image recording modules into a single surveying device. The distance measurement module can accurately measure key parameters such as distance and elevation difference between target points, while the image recording module can simultaneously collect image data of the site environment, construction nodes, or geological features. This integrated design eliminates the need for operators to carry multiple sets of equipment, effectively simplifying equipment carrying and management processes, reducing the burden on field operations, and preventing the disconnect between distance measurement data and image information. This provides convenient support for subsequent data verification and project traceability, significantly improving overall operational efficiency and data reliability.

[0003] In existing integrated surveying devices, the connection between the laser ranging module, the image acquisition module, and the main body of the device relies solely on a plug-in electrical connection structure of the data connector and the data connection interface. No additional mechanical positioning and locking mechanism is provided. The structural stability of this connection method is insufficient. Under conditions such as movement and carrying during subsequent surveying operations, on-site vibration, or external force contact, the connection between the module and the main body is prone to loosening and relative shaking. This can lead to deviations in the accuracy of ranging data and jitter in the image acquisition screen. In severe cases, it may cause interruption of electrical signal transmission, directly affecting the continuity of surveying operations and data reliability. It cannot meet the requirements of high-precision and stable operation in complex scenarios. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of insufficient connection stability, poor fixation reliability, and low loading, unloading and maintenance efficiency caused by the functional modules and the main body of the existing integrated surveying device relying solely on electrical connection and lacking an effective mechanical locking mechanism. Therefore, this invention proposes an integrated ranging and image recording surveying device.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A surveying device integrating ranging and image recording includes a surveying body and a mounting plate that can be mounted on the side wall of the surveying body and detachably connected thereto. The mounting plate integrates a laser ranging module and a photography module to achieve an integrated configuration of ranging and image acquisition functions. The device also includes: A limiting member is disposed on the mounting plate, and the limiting member extends radially along the mounting plate; A rotary compression component is installed on the side wall of the survey body and can rotate circumferentially relative to the survey body around its own axis. A limiting bracket is disposed at the compression end of the rotary compression member. The inner contour of the limiting bracket is adapted to the outer contour of the limiting member. When the mounting plate is assembled into the survey body, the limiting member can be embedded and locked in the limiting bracket. By rotating the rotary compression member, the limiting bracket exerts a pressing effect on the limiting member, thereby realizing the rapid limiting and fixing of the mounting plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the side wall of the surveying body is provided with a slot, and the back of the mounting plate is provided with a plug that mates with the slot. The plug can slide into the slot and form a guiding fit, thereby realizing a detachable assembly connection between the mounting plate and the surveying body.

[0008] Furthermore, the side wall of the survey body is provided with a data port, and the mounting plate integrates a data connector. The data connector is electrically connected to the laser ranging module and / or the photography module. When the mounting plate is assembled to the survey body, the data connector can be inserted into the data port and an electrical connection is established, so as to realize the data transmission and signal interaction between the laser ranging module and / or the photography module and the internal circuit of the survey body.

[0009] Furthermore, the limiting member is a limiting rod structure, which is fixed to the surface of the mounting plate and extends in the radial direction of the mounting plate to provide a locking and engaging reference with the limiting card seat.

[0010] Furthermore, a groove is provided on the side wall of the survey body, and the rotary compression component is accommodated in the groove to achieve a compact arrangement of the rotary compression component and maintain the integrity of the survey body.

[0011] Furthermore, the rotary compressor includes: The uprights are fixed in the groove and extend radially along the survey body, and the number of the uprights is at least two and they are spaced apart; A sleeve is rotatably fitted onto the upright, and the number of the sleeves is at least three and arranged at radial intervals along the upright. The sleeves can rotate circumferentially about the axial direction of the upright. An elastic abutment is disposed on the outside of the sleeve and connected to the limiting seat. When the sleeve rotates, the elastic abutment causes the limiting seat to move due to elastic deformation, thereby applying a clamping force to the limiting component.

[0012] Furthermore, the elastic abutment includes: A sleeve is fixed to the outside of the sleeve base, and the number and distribution of the sleeves correspond one-to-one with the sleeve base; An elastic element, the first end of which is fixed to the inner wall of the sleeve; The sleeve rod has its first end fixedly connected to the second end of the elastic element and extends to the outside of the sleeve. The second end of the sleeve rod is connected to the limiting seat. When the sleeve seat rotates, the elastic element transmits the elastic force to the limiting seat through the sleeve rod, thereby achieving flexible pressing of the limiting component.

[0013] Furthermore, the limiting seat is configured in a C-shape, with the opening size of the limiting seat being slightly smaller than the outer diameter of the limiting rod, and the inner arc surface of the limiting seat forming an interference fit with the outer surface of the limiting rod.

[0014] Furthermore, a connecting groove is provided on the side wall of the survey body. The connecting groove connects the groove and the slot. The cross-sectional dimensions of the limiting member are adapted to the groove opening dimensions of the connecting groove, so that the limiting member can enter the groove through the connecting groove and dock with the limiting card seat during the assembly of the mounting plate.

[0015] Furthermore, the surface of the mounting plate is also provided with a sealing plate, which covers and seals the opening of the groove when the mounting plate is assembled onto the survey body.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The limiting component of this invention extends radially along the mounting plate and is adapted to the internal contour of the limiting bracket. When the mounting plate is assembled to the survey body, the limiting component can be embedded in the limiting bracket and form a preliminary positioning fit. At this time, the rotating compression component is driven to rotate circumferentially by the rotation operation, and the limiting bracket generates a continuous and uniform radial clamping force on the limiting component. This clamping force forms a stable and reliable mechanical locking connection between the mounting plate and the survey body, ensuring the spatial position stability of the laser ranging module and the photography module. This ensures the accuracy and consistency of the ranging data and the stability of the image acquisition, avoiding data offset and signal interruption caused by module shaking, and significantly improving the continuity and data reliability of the survey operation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides a surveying device that integrates distance measurement and image recording. This device is mainly used in field operations in fields such as engineering surveying, geological mapping, and building construction to complete the integrated task of distance measurement and image acquisition.

[0021] The surveying device includes a surveying body 1 and a mounting plate 2 that can be mounted on the side wall of the surveying body 1 and detachably connected to it. The surveying body 1 is a handheld device body, which integrates conventional electronic components such as control circuits, power modules, data processing units, and displays. These components adopt mature solutions in existing technology and will not be described in detail here. The mounting plate 2 has a plate-like structure, and its size matches the mounting area on the side wall of the surveying body 1.

[0022] The mounting plate 2 integrates a laser ranging module 3 and a photography module 4, enabling integrated ranging and image acquisition functions. Specifically, the laser ranging module 3 uses a laser ranging sensor to emit a laser beam and receive reflected signals, calculating the target distance using either the time-of-flight method or the phase method, achieving millimeter-level accuracy. The photography module 4 includes a high-definition camera and image acquisition circuitry, capable of capturing real-time images of the surrounding environment and transmitting the image data to the survey body 1 for storage and processing. The integration of these two modules on the same mounting plate 2 achieves modular configuration of the functional modules, facilitating overall replacement and maintenance.

[0023] In this embodiment, two mounting plates 2 are provided, and a laser ranging module 3 and a photography module 4 are respectively provided on the two mounting plates 2. The structures on the two mounting plates 2 are the same.

[0024] Furthermore, such as Figure 3 As shown, a limiting component 5, a rotating compression component 6, and a limiting bracket 7 are also provided.

[0025] like Figure 2 and Figure 3 As shown, the limiting member 5 is disposed on the mounting plate 2, and extends radially along the mounting plate 2. In this embodiment, the limiting member 5 is a limiting rod structure, which is fixed to the surface of the mounting plate 2 and extends radially along the mounting plate 2. It can be fixedly connected to the mounting plate 2 by welding, bolting, or integral molding. The limiting rod preferably adopts a cylindrical cross-section structure with an outer diameter of 8-12mm, and the material can be stainless steel or aluminum alloy to ensure sufficient strength and corrosion resistance. The setting of the limiting rod provides a locking and mating reference for subsequent cooperation with the limiting seat 7, ensuring the accuracy of assembly positioning. The limiting member 5 can also adopt a square rod, a T-shaped rod, or other irregular cross-section structure, as long as it can form an effective fit with the limiting seat 7.

[0026] like Figure 1 and Figure 2 As shown, the rotary compression component 6 is mounted on the side wall of the survey body 1 and can rotate circumferentially relative to the survey body 1 around its own axis. Specifically, a groove 12 is provided on the side wall of the survey body 1, and the rotary compression component 6 is accommodated within the groove 12. This built-in layout achieves a compact arrangement of the rotary compression component 6 and maintains the overall appearance of the survey body 1, avoiding interference from external protruding structures on handheld operation. The depth and width of the groove 12 match the dimensions of the rotary compression component 6, ensuring that the rotary compression component 6 can rotate smoothly within the groove 12 and will not fall out of the groove 12.

[0027] Furthermore, such as Figure 4 and Figure 5 As shown, the rotary compression component 6 includes a vertical rod 61, a sleeve 62, and an elastic abutment 63. The vertical rod 61 is fixed within the groove 12 and extends radially along the survey body 1. It is fixed to the bottom of the groove 12 by means of threaded connection, press-fit, or bonding. There are at least two vertical rods 61, which are spaced apart. In this embodiment, two vertical rods 61 are preferably provided. The distance between the two vertical rods 61 is determined according to the size of the limiting bracket 7 to ensure that the limiting bracket 7 can provide stable support. The vertical rod 61 can be a smooth round rod structure with a polished surface to reduce frictional resistance.

[0028] The sleeve 62 is rotatably fitted onto the upright 61, and there are at least three sleeves 62 arranged at intervals along the axial direction of the upright 61. In this embodiment, five sleeves 62 are provided on each upright 61, and the sleeves 62 are evenly spaced apart. The inner diameter of the sleeve 62 is slightly larger than the outer diameter of the upright 61, forming a clearance fit, so that the sleeve 62 can rotate circumferentially around the axial direction of the upright 61.

[0029] An elastic abutment 63 is disposed on the outer side of the sleeve 62 and connected to the limiting seat 7. When the sleeve 62 rotates, the elastic abutment 63 causes the limiting seat 7 to displace through elastic deformation, thereby applying a clamping force to the limiting member 5. Specifically, the elastic abutment 63 includes a sleeve 631, an elastic element 632, and a sleeve rod 633. The sleeve 631 is fixed to the outer side of the sleeve 62, and the number and distribution of the sleeves 631 correspond one-to-one with the sleeves 62, ensuring that each sleeve 62 is equipped with a corresponding elastic abutment 63. The first end of the elastic element 632 is fixed to the inner wall of the sleeve 631. The elastic element 632 is preferably a helical compression spring. The first end of the sleeve rod 633 is fixedly connected to the second end of the elastic element 632 and extends to the outside of the sleeve 631. The sleeve rod 633 passes through the end opening of the sleeve 631 and can slide along the axial direction of the sleeve 631. The second end of the sleeve rod 633 is connected to the limiting seat 7. When the sleeve seat 62 rotates, the elastic element 632 transmits the elastic force to the limiting seat 7 through the sleeve rod 633, thereby achieving flexible clamping of the limiting component 5. This elastic clamping method can effectively buffer external impacts and avoid stress concentration and component damage caused by rigid contact.

[0030] like Figure 3 and Figure 4 As shown, the limiting seat 7 is located at the compression end of the rotating compression member 6, that is, fixedly connected to the free end of the sleeve rod 633. The internal contour of the limiting seat 7 is adapted to the external contour of the limiting member 5. In this embodiment, since the limiting member 5 adopts a cylindrical rod structure, the limiting seat 7 is set in a C-shape, with its inner arc surface being arc-shaped. The opening size of the limiting seat 7 is slightly smaller than the outer diameter of the limiting rod. This interference fit design requires the limiting rod to slightly compress the C-shaped opening when inserted, thereby forming a pre-tightening force after engagement. The inner arc surface of the limiting seat 7 and the outer surface of the limiting rod form an interference fit, which ensures both rapid insertion and removal, and sufficient contact area to transmit the clamping force. If the limiting member 5 adopts a square cross-section, the internal contour of the limiting seat 7 is correspondingly set as a square or rectangular groove structure.

[0031] To achieve a guiding fit between the mounting plate 2 and the survey body 1, a slot 8 is provided on the side wall of the survey body 1, and a plug 9 that mates with the slot 8 is provided on the back of the mounting plate 2. The slot 8 has a dovetail or T-slot structure and extends vertically along the side wall of the survey body 1. The plug 9 can slide into the slot 8 and form a guiding fit. The cross-sectional shape of the plug 9 matches the groove shape of the slot 8, forming a sliding fit. This slot-plug fit structure not only provides assembly guidance for the mounting plate 2 and restricts the lateral displacement of the mounting plate 2 relative to the survey body 1, but also enables a detachable assembly connection between the mounting plate 2 and the survey body 1, facilitating quick installation and disassembly.

[0032] like Figure 1 and Figure 2 As shown, to achieve electrical connection, a data port 10 is provided on the side wall of the survey body 1, and a data connector 11 is integrated on the mounting plate 2. The data connector 11 is electrically connected to the laser ranging module 3 and / or the imaging module 4. The data connector 11 is connected to the signal output terminals of the two modules through circuit board traces or wires. When the mounting plate 2 is assembled to the survey body 1, the data connector 11 can be inserted into the data port 10 to establish an electrical connection. The data port 10 and the data connector 11 adopt a foolproof design to ensure correct insertion direction and avoid interface damage caused by reverse insertion. Through this electrical connection, data transmission and signal interaction between the laser ranging module 3 and / or the imaging module 4 and the internal circuit of the survey body 1 are realized. The ranging data and image signals can be transmitted in real time to the control unit of the survey body 1 for processing, display, and storage.

[0033] To facilitate the insertion of the limiting component 5 into the groove 12 and its docking with the limiting bracket 7, a connecting groove 13 is also provided on the side wall of the survey body 1, such as... Figure 4 As shown, the connecting groove 13 connects the recess 12 and the slot 8, forming a continuous channel structure. The cross-sectional dimensions of the limiting member 5 are adapted to the opening dimensions of the connecting groove 13, and the width of the connecting groove 13 is slightly larger than the outer diameter of the limiting rod, leaving an assembly gap. This structural design allows the limiting member 5 to enter the recess 12 through the connecting groove 13 and dock with the limiting seat 7 during the assembly of the mounting plate 2, providing a structural basis for subsequent locking.

[0034] like Figure 1 and Figure 2 As shown, to prevent dust and debris from entering the groove 12, a sealing plate 14 is also provided on the surface of the mounting plate 2. When the mounting plate 2 is assembled on the survey body 1, the sealing plate 14 covers and seals the opening of the groove 12. The sealing plate 14 is integrally formed and connected with the mounting plate 2, and its edge contour matches the opening contour of the groove 12, forming a good sealing effect. This effectively prevents external dust and debris from entering the groove 12, ensuring the normal operation of the rotating compression component 6 and extending the service life of the mechanism.

[0035] The working principle and assembly process of this invention are as follows: When in use, take out the mounting plate 2 containing the photography module 4, and align the insert 9 on the mounting plate 2 with the slot 8 on the survey body 1. At this time, the limiting member 5 is in the limiting seat 7. Then push the mounting plate 2 so that the insert 9 enters the slot 8. During this process, the limiting component 5 pushes the limiting seat 7 to make the sleeve 633 slide into the sleeve 631, compress the elastic element 632, and through the rotation between the upright 61 and the sleeve 62, the limiting seat 7 gradually moves into the groove 12. When the sleeves 631 on the two uprights 61 are parallel to each other, the elastic element 632 is compressed to the maximum extent. As the insert 9 continues to enter the slot 8, under the action of the elastic element 632, the sleeve rod 633 is pushed out of the sleeve 631 until the limiting member 5 abuts against the inner wall of the connecting groove 13, completing the installation work. At this time, under the action of the elastic element 632, the insert 9 and the slot 8 are fixed, thereby realizing the fixation of the photography module 4 and the survey body 1. After the installation is completed, the data connector 11 enters the corresponding data port 10, so that the photography module 4 and the hardware in the survey body 1 are electrically connected. The hardware in the survey body 1 supplies power to the photography module 4, analyzes the signals transmitted by the photography module 4, stores them, and displays the images on the screen in real time. Similarly, after completing the installation of laser ranging module 3, distance information can be stored and displayed in real time; When the laser rangefinder module 3 or the camera module 4 is damaged or needs to be replaced, simply remove the corresponding damaged mounting plate 2 and then install the camera module 4 or the laser rangefinder module 3 that is functioning properly.
