[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, an embodiment of the present invention provides a multifunctional measuring instrument, which includes a housing 10, an insulating tape measure 20, and a laser rangefinder 30. The insulating tape measure 20 includes a tape disc 21 and an insulating tape 22, wherein the tape disc 21 is rotatably disposed in the housing 10, the insulating tape 22 is wound around the tape disc 21, and a tape outlet is disposed on the housing 10, and the insulating tape 22 can be pulled through the tape outlet. The laser rangefinder 30 is disposed in the housing 10, and the housing 10 has a laser port corresponding to the laser rangefinder 30, and the laser port and the tape outlet are both located on the side wall of the housing 10. Such a design enables the measuring instrument to perform both traditional tape measurement and non-contact distance measurement using laser, and is particularly suitable for electrical engineering, construction, and other scenes that require precise measurement and may have safety risks.

[0028] The multifunctional measuring instrument provided in this embodiment adopts the above-mentioned structure. When it is necessary to measure the power system, a multifunctional distance meter consisting of an insulating tape measure 20 and a laser distance meter 30 is used. The insulating tape measure 20 and the laser distance meter 30 can be used simultaneously to measure the distance and height. Different measurement methods can be selected according to different work requirements and different work scenes, thereby solving the problem that the measuring instruments in the related art have relatively single functions, large size and are inconvenient to carry.

[0029] Furthermore, since the laser port and the tape outlet are both located on the side wall of the housing 10, it has the advantage of being easy to operate.

[0030] The advantage of the multifunctional measuring instrument provided in this embodiment is that it combines the traditional insulating tape measure and the modern laser distance measurement technology, which can not only meet the measurement needs in special environments such as electrical engineering, but also provide a faster and more accurate measurement method. The integrated design of the laser distance meter and the insulating tape measure makes the measuring instrument multifunctional, able to adapt to different measurement scenarios and improve work efficiency. The overall design is compact and easy to operate, making it an ideal tool in the fields of electrical engineering, building measurement, etc.

[0031] For example, when conducting electrical engineering measurements, the use of laser ranging can avoid direct contact with live equipment and reduce the risk of electric shock. In construction, laser ranging can quickly measure distances that are difficult to reach or require crossing obstacles, improving the convenience and accuracy of measurements.

[0032] In the related art, the inventors found that the following problems exist in the on-site survey of live working: 1. Carrying a large number of instruments causes great inconvenience to the workers; 2. The measurement accuracy is inaccurate; 3. The measuring tools are not insulated, which poses certain safety risks; 4. The arc distance cannot be measured. The multifunctional measuring instrument provided by this embodiment can solve the above problems, save the physical energy of the workers, improve the safety of the workers during operation, and make more reasonable use of the instruments to perform more accurate surveying and mapping operations.

[0033] like Figure 1 As shown, the multifunctional measuring instrument further includes a rotating base 40 and a rocker 50. The rotating base 40 is rotatably disposed on the housing 10, and the rotating base 40 is connected to the tape reel 21. The rocker 50 is disposed on the rotating base 40, and one end of the rocker 50 away from the rotating base 40 is located outside the housing 10. The rocker 50 is drivingly connected to the tape reel 21 through the rotating base 40 to drive the tape reel 21 to rotate relative to the housing 10. Through the cooperation of the rocker 50 and the rotating base 40, the user can easily control the pulling and drawing of the insulating tape 22, especially when long-distance measurement is required, which can save more effort and improve the efficiency and comfort of measurement.

[0034] In practical applications, the joystick design allows one-handed operation, which can keep the measuring instrument stable even in narrow spaces or at high altitudes, reducing measurement errors caused by hand fatigue. The addition of a rotating base makes the rotation of the tape disc more stable, avoiding sudden stops or accelerations when pulling the tape, ensuring the continuity and accuracy of the measurement.

[0035] like Figure 1 As shown, a clamping block 211 is provided on the outer wall of the tape disc 21, and an annular clamping groove is provided on the inner wall of the housing 10. The annular clamping groove extends along the rotation direction of the tape disc 21, and the clamping block 211 extends into the annular clamping groove. A top column is provided on the rotating base 40, and the top column passes through the tape disc 21 and is rotatably connected to the housing 10. This structural design ensures the stability and accuracy of the rotation of the tape disc 21, avoids the loosening or jamming of the tape disc 21 during the measurement process, ensures the accuracy of the measurement data, and is suitable for occasions requiring high-precision measurement.

[0036] The top column design on the rotating base further enhances the connection stability between the tape reel and the housing, enabling it to maintain good performance under high-intensity or frequent use and extending the service life of the equipment.

[0037] like Figure 1 As shown, the multifunctional measuring instrument also includes a driving motor 60, a battery 70 and a switch 80. The driving motor 60 and the battery 70 are both arranged in the housing 10, and the switch 80 is arranged on the housing 10. The driving motor 60 and the battery 70 are both electrically connected to the switch 80. The driving motor 60 is connected to the tape disc 21 to drive the tape disc 21 to rotate relative to the housing 10. The addition of the driving motor 60 realizes the automatic retraction and release of the insulating tape 22, further improving the convenience of use. Through the automatic retraction and release function of the driving motor 60, the user can operate the insulating tape measure 20 more conveniently, especially when measuring at high altitude or in hard-to-reach places, which greatly improves the safety and convenience of operation.

[0038] The integration of the drive motor enables the intelligent operation of the automatic retraction and extension of the tape measure, especially in large construction sites or scenarios where long-distance measurement is required. Users do not need to worry about the tape rewinding problem, which improves the efficiency of measurement. The drive motor is controlled by the switch, so that the device automatically powers off when not in use, saving power resources and extending the battery life.

[0039] In this embodiment, the switch 80 is a push switch, and the design of the push switch allows the user to quickly start or stop the measuring instrument.

[0040] In addition, the push switch has a fast response speed, and users can adjust the measurement mode instantly during measurement, whether switching from laser ranging to tape measurement, or vice versa, it can be completed quickly, improving work efficiency.

[0041] like Figure 1 As shown, the multifunctional measuring instrument further includes a transmission gear 90, which is disposed in the housing 10, and the drive motor 60 is connected to the tape reel 21 through the transmission gear 90. The addition of the transmission gear 90 ensures that the power transmission between the drive motor 60 and the tape reel 21 is stable, and is suitable for a working environment where the measurement mode needs to be frequently switched.

[0042] The use of transmission gears makes power transmission more efficient and reduces energy loss. Especially when the drive motor is frequently started and stopped, it can maintain good power transmission performance and extend the service life of the equipment.

[0043] Specifically, the multifunctional measuring instrument includes three transmission gears 90, which are arranged in sequence and meshed in sequence. The above structure is adopted to facilitate the arrangement of the drive transmission structure.

[0044] In this embodiment, the laser rangefinder 30 includes a laser module 31, a photoelectric module, a timing module, a power module and a microcontroller module, and the laser module 31, the photoelectric module, the timing module and the power module are all electrically connected to the microcontroller module. The microcontroller module can accurately control the time of laser emission and reception, so as to calculate the distance, and is suitable for engineering and scientific research fields that require high-precision and fast measurement.

[0045] In addition, the microcontroller module of the laser rangefinder can process and store data, which is convenient for users to analyze and manage data, and improves the intelligent level of measurement. As the core of the entire laser rangefinder, the microcontroller module achieves fast and accurate distance measurement by accurately controlling the emission and reception time of the laser. Especially in scientific research experiments, this high-precision measurement capability is crucial for data collection and analysis. At the same time, it can also handle complex measurement environments, such as highly reflective surfaces or strong light interference, and can still maintain measurement accuracy, which is suitable for outdoor measurements or operations in complex environments.

[0046] like Figure 1 As shown, the laser rangefinder 30 further includes an aperture plate 100, a key module 110 and a soft rubber pad 120. The aperture plate 100 is arranged on the housing 10, the key module 110 is arranged on the aperture plate 100, and the soft rubber pad 120 is covered on the key module 110. The arrangement of the soft rubber pad 120 improves the touch of the key, making the user more comfortable during operation, suitable for long-term measurement work, and reducing hand fatigue.

[0047] Moreover, the soft rubber pad not only improves the comfort during operation, but also has waterproof and dustproof functions. Even when working in rainy or dusty environments, it can keep the keys clean and responsive, extending the service life of the device. In addition, the soft rubber pad also has good durability and can withstand frequent pressing, reducing the inconvenience of operation caused by key wear.

[0048] like Figure 1 As shown, the laser rangefinder 30 further includes a display screen 130 and a transparent cover plate 140. The display screen 130 is disposed on the aperture plate 100, and the transparent cover plate 140 covers the display screen 130. The transparent cover plate 140 protects the display screen 130 from being damaged when used in a harsh environment, is suitable for outdoor measurement and operations in complex environments, and ensures the durability of the device and the clear display of data.

[0049] The transparent cover design not only protects the display from damage by the external environment, such as scratches, impacts or bad weather, but also has an anti-glare effect, which allows the measurement data to be clearly displayed even under direct sunlight, improving the convenience of measurement. In addition, the transparent cover also has anti-fingerprint and anti-oil effects, which can keep the display clean and bright after long-term use, improving the efficiency of data reading.

[0050] In this embodiment, a charging port silicone pad 150 is also provided on the housing.

[0051] like Figure 1 As shown, the insulating tape measure 20 also includes a conveying buckle 23, a connecting piece 24 and a pull ring 25. The conveying buckle 23 is arranged on the housing 10, one end of the insulating tape 22 passes through the conveying buckle 23 and is connected to the connecting piece 24, and the connecting piece 24 is connected to the pull ring 25. The design of the conveying buckle 23 and the connecting piece 24 ensures the smoothness of the tape during the pulling process, and the setting of the pull ring 25 facilitates the user's grip during operation, which is suitable for occasions where fast and frequent measurements are required, and improves the convenience and efficiency of measurement.

[0052] Specifically, the use of the conveyor buckle and the connector ensures that the tape will not bend or jam when it is pulled out, and can maintain good measurement accuracy even when taking quick measurements. The pull ring design makes it more comfortable for users to grip, especially when using the tape measure for long-distance measurements or when the hands are inconvenient to operate. The pull ring can provide additional grip and reduce measurement errors caused by hand slippage.

[0053] like Figure 1As shown, in this embodiment, the housing 10 includes a front cover 12 and a rear cover 13, and the front cover 12 and the rear cover 13 are detachably connected. The detachable housing design is convenient for users to replace batteries or perform equipment maintenance, which prolongs the service life of the measuring instrument, is suitable for measurement work that needs to be used in the field or in complex environments for a long time, and ensures the reliability of the equipment and the convenience of maintenance.

[0054] Specifically, the detachable shell design not only facilitates battery replacement, but also makes it easy to clean and maintain the internal part of the device, such as cleaning dust from a tape measure or replacing parts of a laser rangefinder. This is particularly critical in electrical engineering and construction, because these working environments are often harsh and require high maintenance of the equipment. The detachable shell design greatly reduces maintenance costs and increases the service life and reliability of the equipment.

[0055] When working, you can pull the insulating tape measure, align the 0 scale of the insulating tape measure with one end of the target, keep it parallel to the object, pull the insulating tape measure to the other end of the object, and then buckle the pull ring to fix the insulating tape measure. It can be retracted manually or electrically. In addition, the laser rangefinder emits a beam or a series of short pulsed laser beams from the laser module to the target. The photoelectric module in the laser rangefinder receives the laser beam reflected by the target. The timing module in the laser rangefinder measures the time from the emission to the reception of the laser beam. The laser rangefinder can calculate the distance from the measurer to the target. The laser rangefinder is set at the top of the front cover and can be turned on and used directly.

[0056] Specifically, the laser rangefinder is provided with buttons, including switch buttons and function buttons. The switch button and the function button are both set at the top of the front cover, and are used to turn on and off the laser rangefinder. The function button is synchronously set at the top of the front cover. When the laser rangefinder is turned on, the function button can be used to realize the transmission of operation instructions of the laser rangefinder. The laser rangefinder adopts a pulsed laser rangefinder. When working, a beam or a sequence of short pulsed laser beams is emitted from the laser hole to the target. The laser beam reflected by the target is received by the photoelectric module in the laser rangefinder. The timing module in the laser rangefinder measures the time from the emission to the reception of the laser beam. The laser rangefinder can calculate the distance and height from the measurer to the target. The laser rangefinder is provided with a display screen, and the display screen can display the measured data, the status of the laser rangefinder and other information according to the actual measurement of the laser rangefinder. After the microcontroller module is powered on, it controls the laser module to emit a laser beam from the laser hole to the target, controls the timing module to calculate the time, and controls the photoelectric module to receive the laser beam reflected by the target.

[0057] The multifunctional measuring instrument provided by this embodiment perfectly combines the practicality of the traditional tape measure and the accuracy of laser ranging. It is not only suitable for measurement needs in special environments such as electrical engineering and construction, but also provides a faster and more accurate measurement method with its intelligent design. Whether it is daily measurement or operations in complex environments, it can provide an accurate and convenient measurement experience. It is an ideal tool for electrical engineers, building surveyors, scientific research experimenters and aerial workers. Its compact design and intelligent functions not only improve work efficiency, but also ensure the accuracy of measurement, especially in key scenarios that require high-precision measurement, it can play an important role. In addition, the maintainability and durability design of the equipment ensures stable performance in long-term use and harsh environments, and is a capable assistant for professional surveyors in various working environments.
