[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0031] This invention discloses a laser rangefinder with convertible measurement angles, which can solve the technical problem of cumbersome operation in the prior art.

[0032] The technical solution of this application will be described in detail below through specific embodiments:

[0033] See Figure 1 , Figure 2 and Figure 3This application discloses a laser rangefinder with a convertible measurement angle, comprising a rangefinder body 1, a rotating structure 5, and a connecting structure 6. The rotating structure 5 includes a rotating cylinder 505, a connecting block 503, a first elastic element 504, and a support rod 509. The connecting block 503 is rotatably connected to the rotating cylinder 505, and the rangefinder body 1 is rotatably connected to the connecting block 503. The two ends of the first elastic element 504 are respectively connected to the rangefinder body 1 and the connecting block 503, and the first elastic element 504 is used to drive the rangefinder body 1 to rotate relative to the connecting block 503 to an initial position. A fixing groove 512 is provided on the connecting block 503, and the support rod 509 is rotatably connected to the rangefinder body 1. A rubber strip 513 is provided on the support rod 509 at a position corresponding to the fixing groove 512, and the rubber strip 513 is inserted into the fixing groove 512. The connecting structure 6 includes a support plate 601, on which a first positioning groove 510 is provided. The rotating cylinder 505 is installed in the first positioning groove 510, and the rotating cylinder 505 and the support plate 601 are detachably coupled.

[0034] Traditional laser rangefinders require manual adjustment of the entire rangefinder body 1 when changing the measurement angle, which is cumbersome. The rotating cylinder 505 and connecting device of the laser rangefinder with adjustable measurement angle disclosed in this embodiment allow the rangefinder body 1 to be stably placed on the ground. When the measurement angle needs to be changed, the rangefinder body 1 is manually controlled to rotate the connecting block 503 within the inner wall of the rotating cylinder 505, achieving convenient angle conversion without the need for manual adjustment of the entire rangefinder body 1, thus improving measurement efficiency.

[0035] In one embodiment, the rangefinder body 1 is provided with a storage groove 501, and an annular rubber ring 506 is provided on the side wall of the storage groove 501. The end of the first elastic member 504 facing away from the connecting block 503 is located in the storage groove 501, and the limiting ring is used to fix the first elastic member 504.

[0036] The storage slot 501 provides a clear positioning space for the installation of the first elastic element 504. This design allows the first elastic element 504 to be installed in the designated position quickly and accurately when assembling the laser rangefinder, simplifying the installation process.

[0037] The annular rubber ring 506 on the side wall of the storage groove 501 serves to fix the first elastic element 504. The rubber ring 506 has a certain elasticity and friction, which can tightly wrap the first elastic element 504 and prevent it from shifting or loosening during operation.

[0038] In one embodiment, the rotating structure 5 further includes a rotating plate 516 and a second elastic member 517. The rotating plate 516 is rotatably connected to the rotating cylinder 505, with its first end located above the rotating cylinder 505 and its second end extending above the connecting block 503. The two ends of the second elastic member 517 are respectively connected to the rotating cylinder 505 and the first end of the rotating plate 516, and the second elastic member 517 is used to drive the first end of the rotating plate 516 to rotate away from the rotating cylinder 505 so that the second end of the rotating plate 516 abuts against the connecting block 503.

[0039] Driven by the second elastic element 517, the first end of the rotating plate 516 rotates away from the rotating cylinder 505, causing the second end of the rotating plate 516 to abut against the connecting block 503. This design limits the connection block 503, preventing it from rotating freely on the rotating cylinder 505 and enhancing the connection stability between the connecting block 503 and the rotating cylinder 505. During the operation of the laser rangefinder, even under certain external forces, the connecting block 503 can maintain a relatively stable position, thereby ensuring the stability of the measuring angle of the rangefinder body 1 and improving the accuracy of the measurement results.

[0040] By abutting the connecting block 503 against the rotating plate 516, the shaking between the connecting block 503 and the rotating cylinder 505 can be effectively reduced. During the measurement process, any slight shaking may lead to an increase in measurement error, and this design can reduce the possibility of such shaking, making the laser rangefinder more stable and reliable during measurement.

[0041] When fine-tuning of the measuring angle of the rangefinder body 1 is required, the operator can overcome the elastic force of the second elastic element 517, causing the first end of the rotating plate 516 to rotate towards the rotating cylinder 505, thereby releasing the contact between the rotating plate 516 and the connecting block 503. At this time, the connecting block 503 can rotate within a certain range on the rotating cylinder 505, and the operator can adjust the angle of the rangefinder body 1 according to actual needs. After adjustment, the rotating plate 516 is released, and under the action of the second elastic element 517, the rotating plate 516 abuts against the connecting block 503 again, fixing the connecting block 503 at the new angular position. This design not only realizes the function of fine-tuning the angle but also fixes the angle after adjustment, meeting the needs of different measurement scenarios.

[0042] In one embodiment, a rubber plate 519 is provided on the connecting block 503. The rubber plate 519 is located on the upper surface of the connecting block 503, and the rubber plate 519 is annular along the circumference of the connecting block 503, and the rubber plate 519 is located below the second end of the rotating plate 516.

[0043] The rubber plate 519 is located below the second end of the rotating plate 516. When the second end of the rotating plate 516 abuts against the connecting block 503, the rubber plate 519 increases the friction between the rotating plate 516 and the connecting block 503. This increased friction can better restrict the rotation of the connecting block 503, further enhancing the connection stability between the connecting block 503 and the rotating cylinder 505. This allows the rangefinder body 1 to maintain a more stable angle during measurement, reducing angular deviations caused by external factors or equipment vibration, thereby improving the accuracy of the measurement results.

[0044] During the operation of the laser rangefinder, the equipment may be subjected to various forces, such as slight touches from the operator or vibrations from the surrounding environment. The presence of the rubber plate 519 effectively prevents relative sliding between the rotating plate 516 and the connecting block 503, ensuring that the limiting effect of the rotating plate 516 on the connecting block 503 is always effective and guaranteeing the overall stability of the equipment.

[0045] In one embodiment, a locking groove 514 and a limiting rod 515 are provided on the top of the rotating cylinder 505. The limiting rod 515 is located within the locking groove 514 and is perpendicular to the axial direction of the rotating cylinder 505. A rotating plate 516 is also located within the locking groove 514 and is rotatably connected to the limiting rod 515. A protrusion 518 is also provided at the second end of the rotating plate 516. The protrusion 518 is located on the side of the rotating plate 516 facing the connecting block 503. By using the protrusion 518 to press against the rubber plate 519, the resistance of the connecting block 503 when rotating relative to the rotating cylinder 505 can be increased, thereby creating a damping effect.

[0046] A slot 514 is provided at the top of the rotating cylinder 505 to house the limiting rod 515 and the rotating plate 516, making the overall structure more compact and reasonable. This design makes full use of the space at the top of the rotating cylinder 505, reduces the volume occupied by parts, helps to reduce the overall size of the laser rangefinder, and makes it easier to carry and use.

[0047] In one embodiment, the rangefinder body 1 is provided with a connecting groove 507, and the support rod 509 is rotated to allow the support rod 509 to enter or leave the connecting groove 507.

[0048] By rotating the support rod 509 to move it into or out of the connecting slot 507, the operator can quickly switch between the measuring and storage states. When measurement is needed, rotating the support rod 509 out of the connecting slot 507 and adjusting it to a suitable angle allows the support rod 509 to connect with the connecting block 503, thus fixing the rangefinder body 1 to the connecting block 503. After measurement, rotating the support rod 509 back into the connecting slot 507 facilitates storage and carrying, greatly improving the convenience and efficiency of operation.

[0049] In one embodiment, the rangefinder body 1 is provided with a first positioning groove 510, which is located on the side wall of the connecting groove 507. A rubber block 511 is provided on the support rod 509 at a position corresponding to the first positioning groove 510, and the rubber block 511 engages with the first positioning groove 510.

[0050] A first positioning groove 510 is provided on the side wall of the connecting groove 507, providing a clear installation position for the rubber block 511 on the support rod 509. When the support rod 509 is connected to the rangefinder body 1, the rubber block 511 can be accurately inserted into the first positioning groove 510, realizing the quick and accurate installation of the support rod 509, avoiding connection instability caused by installation position deviation, and improving the connection accuracy between the support rod 509 and the rangefinder body 1.

[0051] In one embodiment, a round rod 508 is provided on the side wall of the connecting groove 507, and a support rod 509 is rotatably connected to the round rod 508. When the support rod 509 is retracted, it can be completely retracted into the connecting groove 507. At this time, the rubber block 511 on the support rod 509 is engaged in the second positioning groove 602 to prevent the support rod 509 from rotating arbitrarily. When the support rod 509 is lowered, the rubber strip 513 on the support rod 509 can be inserted into the fixing groove 512 on the connecting block 503. At this time, the rangefinder body 1 and the connecting block 503 are fixed to each other.

[0052] The support rod 509 is rotatably connected to the round rod 508 on the side wall of the connecting slot 507, allowing the support rod 509 to be completely retracted into the connecting slot 507 when retracted. This design makes full use of the space on the rangefinder body 1, making the laser rangefinder more compact when not in use, facilitating its portability and storage, and is especially suitable for use in environments with limited space, such as outdoor measurements and narrow work areas. The rotatable connection makes the storage of the support rod 509 simple and convenient; the operator only needs to gently rotate the support rod 509 to retract it into the connecting slot 507, without complicated disassembly or folding steps, thus improving efficiency.

[0053] In one embodiment, the rotating structure 5 further includes a first damping rod 502, the rangefinder body 1 is connected to the connecting block 503 through the first damping rod 502, and the first elastic element 504 is wrapped around the first damping rod 502.

[0054] The first damping rod 502 provides damping for the rotation between the rangefinder body 1 and the connecting block 503. When adjusting the measuring angle of the rangefinder body 1, the operator can feel a moderate resistance. This resistance makes the angle adjustment process smoother and more controllable, and allows the rangefinder body 1 to be adjusted to the required angle more accurately. This avoids angle deviation caused by excessive or uncontrolled rotation and improves the accuracy of angle adjustment.

[0055] When the laser rangefinder is subjected to external interference, such as a slight collision or vibration, the damping effect of the first damping rod 502 can buffer these external forces and prevent sudden changes in the angle of the rangefinder body 1. It enables the angle change to be slower and smoother, thereby ensuring the angular stability of the rangefinder body 1 during the measurement process.

[0056] See Figure 1 and Figure 4 In one embodiment, the connecting structure 6 includes a rectangular strip 607 and a third elastic member 609. The rectangular strip 607 is slidably connected to the support plate 601, and the rotating cylinder 505 is located on the moving path of the rectangular strip 607. The two ends of the third elastic member 609 are respectively connected to the support plate 601 and the rectangular strip 607, and the third elastic member 609 is used to drive the rectangular strip 607 to move toward the rotating cylinder 505.

[0057] When the rotating cylinder 505 needs to be adjusted to a specific position, the rectangular bar 607 can accurately cooperate with the corresponding part of the rotating cylinder 505 under the action of the third elastic element 609, ensuring the positional accuracy of the rotating cylinder 505 and thus improving the measurement accuracy of the laser rangefinder.

[0058] The third elastic element 609 drives the rectangular bar 607 to move toward the rotating cylinder 505, thus automating the connection. When installing or adjusting the rotating cylinder 505, there is no need to manually operate the rectangular bar 607 for connection; simply place the rotating cylinder 505 in the appropriate position, and the rectangular bar 607 will automatically complete the connection under the action of the third elastic element 609, greatly simplifying the operation process and improving work efficiency.

[0059] When the rotating cylinder 505 undergoes slight displacement due to external factors, the third elastic element 609 can automatically adjust the position of the rectangular bar 607 according to the displacement, ensuring that the rectangular bar 607 always maintains a good connection with the rotating cylinder 505. This adaptive adjustment capability can adapt to different measurement conditions and environmental changes, ensuring the stability and reliability of the connection.

[0060] In one embodiment, a rubber block 610 is provided at one end of the rectangular bar 607 facing the rotating cylinder 505. When the rectangular bar 607 moves toward the rotating cylinder 505, squeezing the rubber block 610 can increase the friction, thereby preventing the rotating cylinder 505 from rotating relative to the support plate 601.

[0061] The rubber block 610 has good elasticity and a high coefficient of friction. When the rectangular strip 607 moves toward the rotating cylinder 505 and presses against the rubber block 610, the rubber block 610 comes into close contact with the surface of the rotating cylinder 505, generating a large frictional force. This frictional force effectively prevents the rotating cylinder 505 from rotating relative to the support plate 601, ensuring that the rotating cylinder 505 maintains a stable posture during the measurement process.

[0062] In one embodiment, the connecting structure 6 further includes a connecting frame 606 and a second damping rod 608. The connecting frame 606 is mounted on the support plate 601 to form a guide groove, providing a clear installation space and motion guide for the rectangular bar 607, the third elastic element 609, and the second damping rod 608. The rectangular bar 607, the third elastic element 609, and the second damping rod 608 are all installed within the guide groove. The second damping rod 608 is connected to the connecting frame 606, the rectangular bar 607 slides with the damping rod, and the third elastic element 609 is wound around the second damping rod 608.

[0063] The connecting frame 606 integrates all components into a relatively enclosed space, enhancing the overall integrity of the connecting structure 6. This structure can better withstand external forces and vibrations, reducing the risk of connection failure due to loosening or displacement of components.

[0064] The second damping rod 608 is connected to the connecting frame 606 and slides in engagement with the rectangular bar 607. During the movement of the rectangular bar 607, the second damping rod 608 provides appropriate damping force, making the movement of the rectangular bar 607 smoother and slower. This damping effect prevents the rectangular bar 607 from generating impact forces due to rapid movement, reducing damage to other components, and also improving the accuracy and controllability of operation.

[0065] In one embodiment, the support plate 601 is provided with a second positioning groove 602 and a notch 604 located on the side wall of the second positioning groove 602, the top of the notch 604 extending to the upper surface of the support plate 601. A rubber ring 603 and a positioning block 605 are provided on the outer side wall of the rotating cylinder 505. The rubber ring 603 is annular along the circumference of the rotating cylinder 505, and the rubber ring 603 engages with the second positioning groove 602, while the positioning block 605 engages with the notch 604.

[0066] The rubber ring 603 engages with the second positioning groove 602, and the positioning block 605 engages with the notch 604, forming a double fixing mechanism. The elasticity of the rubber ring 603 allows it to fit tightly against the inner wall of the second positioning groove 602, generating significant friction and effectively preventing the rotating cylinder 505 from shifting horizontally. After the positioning block 605 is inserted into the notch 604, it restricts the rotation of the rotating cylinder 505 in the circumferential direction, ensuring that the rotating cylinder 505 maintains a stable position on the support plate 601, greatly improving the stability of the connection.

[0067] The second positioning groove 602 and the notch 604 provide precise positioning for the rotating cylinder 505. When installing the rotating cylinder 505, simply align the positioning block 605 with the notch 604 and insert it, while simultaneously engaging the rubber ring 603 into the second positioning groove 602. This allows the rotating cylinder 505 to be installed quickly and accurately in the designated position, avoiding measurement errors caused by installation deviations.

[0068] In one embodiment, the rangefinder body 1 is provided with a display screen 2, a laser generator 3, and a laser receiver 4. The laser generator 3 and the laser receiver 4 are located on the same side wall of the rangefinder body 1, and the display screen 2 is located on the other side wall of the rangefinder body 1.

[0069] Placing the laser generator 3 and laser receiver 4 on the same side wall of the rangefinder body 1 conforms to the basic principles and workflow of laser ranging. The laser generator 3 emits a laser beam, and the laser receiver 4 is responsible for receiving the reflected laser signal. This same-side layout makes the laser emission and reception path more direct and efficient, reducing energy loss and interference during laser propagation.

[0070] The display screen 2 is located on another side wall of the rangefinder body 1, separate from the side wall where the laser generator 3 and laser receiver 4 are located. This layout allows the operator to easily observe the measurement results on the display screen 2 while holding the rangefinder for measurement, without being interfered with by the laser emitting and receiving components. The operator can directly view the data on the display screen 2 while pointing the laser emitting and receiving sides at the target object, improving the convenience and efficiency of operation.

[0071] In one embodiment, a positioning frame 611 is provided on the rangefinder body 1. The inner wall of the positioning frame 611 is slidably connected to the support plate 601, and the connecting frame 606 is engaged with the positioning frame 611. When the laser rangefinder with convertible measurement angle is not in use, the support plate 601 can be removed from the rotating cylinder 505, and then the support plate 601 can be stored behind the rangefinder body 1 by the cooperation of the connecting frame 606 and the positioning frame 611.

[0072] When the laser rangefinder is not in use, the support plate 601 can be removed from the rotating cylinder 505 and stored behind the rangefinder body 1 through the cooperation of the connecting frame 606 and the positioning frame 611, which greatly saves storage space. This compact storage method makes the laser rangefinder more convenient to carry or store. Whether placed in a toolbox, backpack or other storage container, it will not take up too much space and improves space utilization.

[0073] Through the above embodiments, this application has the following beneficial effects or advantages: The laser rangefinder with convertible measurement angle disclosed in this application, by setting a rotating structure 5, allows the rangefinder body 1 to rotate relative to the connecting block 503 and the rotating cylinder 505. When it is necessary to change the measurement angle, there is no need to manually lift the entire rangefinder body 1; simply rotating the rangefinder body 1 is sufficient to adjust the angle. The operation is simple and convenient, greatly improving measurement efficiency. The first elastic element 504 can drive the rangefinder body 1 to rotate relative to the connecting block 503 to the initial position, so that the rangefinder body 1 can automatically reset after each measurement, facilitating accurate measurement in the next measurement. The design of the rotating plate 516, the second elastic element 517, the rubber plate 519, and the rubber strip 513 on the support rod 509 and the fixed groove 512 in the rotating structure 5 can enhance the connection stability between the rangefinder body 1 and the connecting block 503, and between the connecting block 503 and the rotating cylinder 505, reduce shaking during the measurement process, and improve measurement accuracy. The connecting structure 6 employs a rectangular bar 607, a third elastic element 609, a rubber ring 603, and a positioning block 605, enabling a detachable connection between the rotating cylinder 505 and the support plate 601, facilitating the installation, disassembly, and transport of the laser rangefinder. The first damping rod 502 and the second damping rod 608 provide a certain damping force, ensuring smoother rotation of the rangefinder body 1 and the rectangular bar 607, preventing excessive rotation or swaying from affecting the measurement results.
