Detailed Implementation

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Figures 1-6 In one embodiment of this utility model, a laser mapping and positioning device includes a laser mapping instrument 1 and a mounting cover 3 threaded onto the laser mapping instrument 1. An optical lens 2 is fixedly mounted on the laser mapping instrument 1. The mounting cover 3 has a battery compartment 4, which is covered by a closing cover 5. The mounting cover 3 has a protective mechanism 6. The protective mechanism 6 includes a triaxial accelerometer 601, a wireless communication module 602, and a microcontroller 603. A mounting ring 604 is rotatably mounted inside the mounting cover 3, and a toothed ring 605 is sleeved on the mounting ring 604. The mounting cover 3 has multiple sets of annularly distributed closing plates 606, which are rotatably connected to the mounting cover 3 via handles 607. A fourth gear 608 is sleeved on each of the multiple handles 607. A first torsion spring 609 is connected to the upper handle 607, a first gear 610 is sleeved on it, a first rack 611 is slidably installed inside the mounting cover 3, a first metal block 612 is fixedly installed on the first rack 611, a first solenoid 613 is fixedly installed inside the mounting cover 3, a first coil 614 is sleeved on the first solenoid 613, a first power supply device 615 is provided below the first solenoid 613, and the two ends of the first coil 614 are respectively connected to the positive and negative terminals of the first power supply device 615. The first solenoid 613 and the first metal block 612 are correspondingly arranged. Through the protection mechanism 6, when the optical lens 2 is not in use, multiple sets of closing plates 606 are in a closed state, working together with the mounting cover 3 to keep the optical lens 2 in a closed state, preventing the optical lens 2 from being damaged by collision.

[0028] In this embodiment, reference Figure 2 , Figure 3 and Figure 4As shown, multiple sets of fourth gears 608 are meshed with gear rings 605. The two ends of the first torsion spring 609 are fixedly connected to the handle 607 and the mounting cover 3, respectively. The first rack 611 is meshed with the first gear 610. When the positioning device is not in use, the handle 607 and the closing plate 606 are both in a closed state under the action of the first torsion spring 609, effectively protecting the optical lens 2 from impact or scratches. When the optical lens 2 needs to be used, the locking mechanism 7 is in a locked state, and the handle 607 can rotate freely. The first power supply device 615 is turned on to engage with the first solenoid coil 614, causing a current to be generated around the first solenoid 613. The magnetic field attracts the first metal block 612, causing the first rack 611 to slide. This, in conjunction with the first gear 610, enables the handle 607 and the closing plate 606 to flip. The gear ring 605 and the fourth gear 608 enable the rotation of multiple sets of closing plates 606, exposing the optical lens 2 for easy use. When the locking mechanism 7 is in the open state, the connecting bracket 709 slides to the left and engages between the two sets of positioning rods 711. This causes the two sets of second racks 706 to slide and engage with the second gear 705, causing the mounting shaft 703 to drive the pawl 702 to deflect, releasing the restriction on the ratchet 701, and allowing the handle 607 to rotate freely.

[0029] In this embodiment, reference Figure 5 , Figure 6As shown, the mounting cover 3 is equipped with a locking mechanism 7 for controlling the closing plate 606. The locking mechanism 7 includes two sets of symmetrically distributed ratchet wheels 701 sleeved on the upper handle 607. The mounting cover 3 is equipped with two sets of pawls 702 corresponding to the ratchet wheels 701, and both sets of pawls 702 are rotatably connected to the mounting cover 3 through a mounting shaft 703. A second torsion spring 704 is sleeved on the mounting shaft 703, and the two ends of the second torsion spring 704 are fixedly connected to the pawls 702 and the mounting cover 3, respectively. A second gear 705 is sleeved on the lower end of each of the two sets of mounting shafts 703, and two sets of second racks 706 are slidably installed in the mounting cover 3 and mesh with the two sets of second gears 705. A slide rod 707 is fixedly installed in the mounting cover 3. The components 06 are fixedly connected by a connecting bracket 709. The connecting bracket 709 is slidably sleeved with the slide rod 707, and a first spring 708 is sleeved on the slide rod 707. The two ends of the first spring 708 are fixedly connected to the connecting bracket 709 and the mounting cover 3, respectively. Two sets of symmetrically distributed positioning brackets 710 are slidably installed inside the mounting cover 3, and positioning rods 711 are fixedly installed on each of the two sets of positioning brackets 710. Both sets of positioning rods 711 are movably engaged with the connecting bracket 709. A third rack 714 is fixedly installed on each of the two sets of positioning brackets 710. A rotating rod 715 is rotatably installed inside the mounting cover 3, and a third gear 716 is sleeved on the rotating rod 715. The third gear 716 meshes with the two sets of third racks 714, respectively. A third rack 714 on the right side is fixedly installed with... The second metal block 718 has a third torsion spring 717 sleeved on the rotating rod 715. Both sets of positioning rods 711 have stop blocks 712 fixedly sleeved on them. Both sets of positioning rods 711 have a second spring 713 movably sleeved on them, with both ends of the second spring 713 fixedly connected to the stop block 712 and the mounting cover 3, respectively. The mounting cover 3 contains second solenoids 719 corresponding to the second metal block 718, with a second solenoid coil 720 sleeved on each solenoid. The mounting cover 3 also contains a second power supply device 721, with both ends of the second solenoid coil 720 connected to the positive and negative terminals of the second power supply device 721, respectively. When the triaxial accelerometer 601 detects a collision or impact on the positioning device, a signal is transmitted via the wireless communication module 602. The microcontroller 603 controls the first power supply device 615 to shut down. Under the action of the first torsion spring 609, multiple handles 607 and closing plate 606 return to the closed state. The second power supply device 721 turns on, and together with the second solenoid coil 720, the second solenoid tube 719 and the second metal block 718, it attracts the second rack 706 upward. Together with the second gear 705, it causes the two sets of positioning rods 711 to move to both sides synchronously, releasing the restriction on the connecting frame 709. Under the action of the first spring 708 and the second torsion spring 704, the pawl 702 returns to its original position and limits the ratchet 701. The handle 607 cannot rotate freely, and the closing plate 606 is in a firmly closed state, maintaining effective protection for the optical lens 2.

[0030] In this embodiment, when the positioning device is not used, the handle 607 and the closing plate 606 are both in a closed state under the action of the first torsion spring 609, effectively protecting the optical lens 2 from impact or scratches. When the optical lens 2 needs to be used, the locking mechanism 7 is in an open state, allowing the handle 607 to rotate freely. The first power supply device 615 is turned on, and the first solenoid coil 614 generates a magnetic field around the first solenoid 613, attracting the first metal block 612. This causes the first rack 611 to slide, and in conjunction with the first gear 610, the handle 607 and the closing plate 606 are flipped. In conjunction with the gear ring 605 and the fourth gear 608, multiple sets of closing plates 606 are rotated, exposing the optical lens 2 for easy use. When the locking mechanism 7 is in an open state, the connecting bracket 709 slides to the left and engages between the two sets of positioning rods 711, thereby driving the two sets of second racks 706 to slide and in conjunction with the second gear 705, causing the mounting shaft 703 to drive the pawl 702 to deflect. The restriction on ratchet 701 is lifted, allowing handle 607 to rotate freely. When the triaxial accelerometer 601 detects a collision or impact on the positioning device, it transmits a signal to microcontroller 603 via wireless communication module 602. Microcontroller 603 controls the first power supply device 615 to shut down. Under the action of the first torsion spring 609, multiple handles 607 and closing plate 606 return to the closed state. The second power supply device 721 is turned on, and together with the second solenoid coil 720, the second solenoid tube 719, and the second metal block 718, it attracts the second rack 706 upward. Together with the second gear 705, it causes the two sets of positioning rods 711 to move synchronously to both sides, releasing the restriction on connecting frame 709. Under the action of the first spring 708 and the second torsion spring 704, pawl 702 returns to its original position and limits ratchet 701. Handle 607 cannot rotate freely, and closing plate 606 is in a firmly closed state, maintaining effective protection for optical lens 2.
