Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a portable measuring instrument. Background Technology

[0002] With the rapid development of robotics technology, robots are increasingly being used in fields such as environmental perception, autonomous navigation, and high-precision operations (e.g., grasping, assembly, and painting). In these applications, robots need to accurately acquire three-dimensional information about the working environment, object dimensions, and their own pose, a process that typically relies on environmental measurement and calibration techniques.

[0003] An existing patent (authorization announcement number: CN219456483U) discloses a portable distance measuring device. The key technical points of the solution are: by inserting the user's arm between two arc-shaped seats and two elastic straps, the device is fitted onto the surface of the arm using the elasticity of the straps, freeing the hands; or by inserting fingers into the retrieval slot to remove the handle from the receiving slot and carrying the distance measuring device by lifting the handle, the pressure on the hands from holding it for a long time can also be relieved. A protective shell is provided to be fitted onto the surface of the protrusion and the laser distance measuring unit when distance measuring is not needed. An elastic snap-fit ​​mechanism is used to fix the protective shell to the surface of the protrusion to protect the laser distance measuring unit, preventing wear and tear and reducing its service life. At the same time, the elastic strap at the bottom allows the distance measuring device to be fitted onto the user's arm for carrying, freeing the hands; or by removing the handle from the receiving slot and carrying the distance measuring device by lifting the handle, the pressure on the hands from holding it can also be reduced.

[0004] However, the above technical solutions still have certain defects. In outdoor work, uneven bottom surfaces can easily cause the platform to be unstable, causing the measuring instrument to slip and making it impossible to effectively adjust the range of support on the ground. In scenarios that require precise aiming or long-term continuous measurement, handheld operation can introduce errors due to human shaking, which seriously affects the reliability and consistency of measurement data. Therefore, a portable measuring instrument is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a portable measuring instrument to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable measuring instrument includes a rangefinder. The rangefinder has an imaging button on its top, a switch button for controlling the rangefinder's on / off position on its side, a strap for easy handling on its side, a detachable tripod at its bottom, an adjustment component for adjusting the focus near the strap, and a battery replacement assembly at its bottom.

[0008] The tripod includes a triangular connecting seat, a threaded rod rotatably mounted on the inner wall of the triangular connecting seat, a movable ring threadedly connected to the threaded rod, the movable ring being disposed at the top of the triangular connecting seat, three sets of hinges extending from the side wall of the movable ring, and connecting arms rotatably mounted on the three sets of hinges respectively, a support rod rotatably mounted on the end of the connecting arm away from the hinge, a support foot rotatably mounted on the bottom end of the support rod, and the top end of the support rod rotatably connected to the triangular connecting seat;

[0009] The support rod has multiple connection holes, and there are three sets of support rod, support legs and connecting arms. The support legs are made of rubber material.

[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0011] As a further embodiment of this utility model: the adjustment component includes a focusing ring rotatably fitted outside the lens of the rangefinder, the outer side wall of the focusing ring being provided with anti-slip texture; a scale bar is provided on the side wall of the rangefinder near the focusing ring, and an indicator mark pointing to the scale bar is provided on the focusing ring.

[0012] As a further embodiment of this utility model: the disassembly and assembly assembly includes a battery compartment located at the bottom of the rangefinder, a power supply battery installed inside the battery compartment, and a compartment cover threadedly connected to the opening of the battery compartment.

[0013] As a further embodiment of this utility model: a magnetic block is fixedly installed at the bottom of the rangefinder, and an adsorption part made of ferromagnetic material is provided at the top of the threaded rod, and the magnetic block and the adsorption part are magnetically attracted and fixed to each other.

[0014] As a further improvement of this utility model: the rangefinder is also equipped with a distance sensor, an image sensor and an attitude sensor; the rangefinder is also equipped with an embedded processing unit, which is electrically connected to the distance sensor, the image sensor, the attitude sensor and the communication interface module, and is used to process and fuse multi-sensor data.

[0016] As a further embodiment of this invention: both the switch button and the imaging button are electrically connected to the embedded processing unit, and the embedded processing unit is configured to respond to the operation signals of the switch button and the imaging button, and control the working state of the communication interface module.

[0017] As a further improvement of this invention, the rangefinder can communicate with an external robot controller via the wired Ethernet interface or the wireless communication module.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a tripod and a threaded rod to control the up-and-down movement of the moving ring, thereby controlling the outward extension range of the support leg. The rubber support foot increases friction and prevents slippage. At the same time, multiple connecting holes on the support rod provide a two-stage fine adjustment function. Users can fix the hinge point of the connecting arm and the support rod to different holes using pins. After unfolding, the linkage mechanism forms a stable triangular structure with high rigidity and is not easy to shake.

[0020] 2. By setting up a magnetic block, this utility model only requires the bottom of the rangefinder to be close to the top of the threaded rod of the tripod. When the magnetic block and the adsorption part enter the effective range of their respective magnetic fields, the strong magnetic force will automatically attract them to each other and make them stick together. At the same time, when removing them, only a vertical pulling force exceeding the magnetic attraction force is needed to easily remove them. The magnetic block can also be attached to the end of the robot for continuous measurement without the need for manual handling. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-4 As shown, a portable measuring instrument includes a rangefinder 1. The rangefinder 1 has an imaging button 8 on its top, a switch button 7 on its side for controlling the switch, a strap 5 on its side for easy handling, a detachable tripod 2 at its bottom, an adjustment component 4 for adjusting the focus near the strap 5, and a battery replacement component 6 at its bottom.

[0031] In this embodiment, the user presses the power button 7 to start the device, adjusts the focal length of the rangefinder 1 lens using the adjustment component 4 to ensure the target object is clearly visible in the imaging system, and then presses the imaging button 8 on top. This button triggers two functions: first, capturing a visual image; second, emitting a laser and calculating the time / phase difference of the returning light to obtain accurate distance data. The processor inside the device processes this information. The strap 5 allows the user to hang the instrument on their hand for easy movement and access. When high-precision or long-term measurements are required, the user installs the detachable tripod 2 on the bottom of the instrument and unfolds it. The disassembly and assembly component 6 allows the user to easily open the battery compartment 61 to replace or install batteries, ensuring continuous power supply for the device in the field or during long-term operation.

[0032] In one embodiment, such as Figure 2As shown, the tripod 2 includes a triangular connecting seat 21, a threaded rod 22 rotatably mounted on the inner wall of the triangular connecting seat 21, and a movable ring 23 threadedly connected to the threaded rod 22. The movable ring 23 is located at the top of the triangular connecting seat 21. Three sets of hinges extend from the side wall of the movable ring 23, and each of the three sets of hinges is rotatably mounted with a connecting arm 24. A support rod 25 is rotatably mounted at the end of the connecting arm 24 away from the hinge. A support foot 26 is rotatably mounted at the bottom end of the support rod 25, and the top end of the support rod 25 is rotatably connected to the triangular connecting seat 21. The support rod 25 has multiple connecting holes, and there are three sets of support rod 25, support foot 26, and connecting arm 24. The support foot 26 is made of rubber material. When the user rotates the threaded rod 22 at the center of the triangular connecting seat 21, the rotational motion of the threaded rod 22 is converted into the linear motion of the movable ring 23 through the threaded joint. Rotating the threaded rod 22 clockwise moves the moving ring 23 downwards; rotating it counterclockwise moves the moving ring 23 upwards. The moving ring 23, through three sets of hinges on its sidewall, drives one end of each of the three connecting arms 24 to move. This outward thrust acts on the support rod 25. Since the top of the support rod 25 is rotatably connected to the triangular connecting seat 21, when the moving ring 23 moves upwards, this outward thrust forces the entire support rod 25 to open outwards around its top axis, thus expanding the tripod 2 and increasing its height. When the moving ring 23 moves downwards, the height decreases. Simultaneously, the rubber support feet 26 increase friction to prevent slippage. Multiple connecting holes on the support rod 25 provide two-stage fine adjustment. Users can fix the hinge points of the connecting arms 24 and the support rod 25 to different hole positions using pins. After unfolding, the linkage mechanism forms a stable triangular structure with high rigidity and is not easily shaken.

[0033] As a supplement: a magnetic block 3 is fixedly installed at the bottom of the rangefinder 1, and an adsorption part made of ferromagnetic material is provided at the top of the threaded rod 22. The magnetic block 3 and the adsorption part are magnetically attracted and fixed to each other. When the user needs to install the tripod 2, simply place the bottom of the rangefinder 1 close to the top of the threaded rod 22 of the tripod 2. When the magnetic block 3 and the adsorption part enter the effective range of their respective magnetic fields, the strong magnetic force will automatically attract them to each other and make them fit together. This magnetic force is sufficient to automatically correct slight positional deviations in the horizontal direction and generate sufficient vertical preload to firmly fix the two parts together to form a stable whole. At the same time, it can be easily removed by providing only a vertical pull force exceeding the magnetic attraction force. The magnetic block 3 can be attached to the robot end for continuous measurement without manual handling.

[0034] In one embodiment, such as Figure 3As shown, the adjustment assembly 4 includes a focusing ring 41 rotatably fitted around the lens of the rangefinder 1. The outer wall of the focusing ring 41 has anti-slip texture. A scale bar 43 is provided on the side wall of the rangefinder 1 near the focusing ring 41. An indicator mark pointing to the scale bar 43 is provided on the focusing ring 41. When the user rotates the focusing ring 41, its internal mechanical structure converts the rotational motion into the linear motion of the optical lens inside the lens. When the focusing ring 41 rotates, the indicator mark moves relative to the fixed scale bar 43. By observing which scale value on the scale bar 43 the indicator mark aligns with, the user can directly read the approximate current focus distance, which helps in adjusting the focus.

[0035] In one embodiment, such as Figure 4 As shown, the disassembly and assembly component 6 includes a battery compartment 61 located at the bottom of the rangefinder 1, a power supply battery 62 installed inside the battery compartment 61, and a cover 63 threadedly connected to the opening of the battery compartment 61. When the battery needs to be replaced, the user can simply rotate the cover 63 to remove it, making it easy to replace the internal battery without having to carry a large continuous power generation device.

[0036] In one embodiment, such as Figure 1 As shown, the rangefinder 1 also includes a distance sensor, an image sensor, and an attitude sensor. The rangefinder 1 also includes an embedded processing unit electrically connected to the distance sensor, image sensor, attitude sensor, and communication interface module. This embedded processing unit processes and fuses data from multiple sensors. The communication interface module includes a wired Ethernet interface and a wireless communication module, which includes Wi-Fi and Bluetooth. The distance sensor is a laser sensor that directly measures the straight-line distance to the target object using laser light. The image sensor, i.e., a camera, captures visual images of the target area. Simultaneously, the attitude sensor includes a gyroscope and an accelerometer, used to measure the device's attitude angle and motion state in real time. The embedded processing unit fuses the raw data from these three sensors for continuous tracking measurement. Data exchange with the outside world is achieved through the wireless communication module, and control is achieved through an external controller, making the measurement process more convenient and providing more comprehensive information.

[0037] In one embodiment, such as Figure 3As shown, both the switch button 7 and the imaging button 8 are electrically connected to the embedded processing unit. The embedded processing unit is configured to respond to the operation signals of the switch button 7 and the imaging button 8 and control the working state of the communication interface module. The rangefinder 1 can communicate with an external robot controller through the wired Ethernet interface or the wireless communication module. When the user presses the buttons, they send electronic signals to the embedded processing unit to inform the CPU whether the user's intention is to turn the device on / off or to perform a measurement. Through these communication channels, the rangefinder 1 establishes a bidirectional data link with the external robot controller to broaden the application scenarios of the measuring instrument and make it more competitive in the market.

[0038] The above embodiment discloses a portable measuring instrument. The user can easily carry or retrieve the instrument using the strap 5. The magnetic block 3 at the bottom of the instrument is aligned with the suction point at the top of the threaded rod 22 of the tripod 2, and the instrument is quickly and firmly attached using magnetic force. Manually rotating the threaded rod 22 simultaneously unfolds the three support legs via a linkage mechanism, achieving rapid leveling. Pressing the switch button 7 starts the device. Manually rotating the focusing ring 41 with anti-slip texture and observing the scale bar 43 allows for precise pre-focusing. The embedded processing unit simultaneously receives the multi-source data and performs fusion processing to obtain accurate measurement results. If the battery is low, the threaded compartment cover 63 at the bottom can be easily unscrewed to replace the battery and ensure power supply.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
