Description

Technical Field

[0001] The utility model relates to the technical field of level instruments, in particular to a level instrument with an auxiliary positioning mechanism. Background Art

[0002] The laser level is a device that directs the laser beam emitted by a laser into the telescope barrel so that it emits a horizontal laser beam along the sighting axis direction, and installs a zone plate in front of the telescope objective to diffract the horizontal laser beam. After the telescope is focused, a bright and fine cross-shaped laser light plate is obtained within the focusing range of the zone plate, thereby accurately aiming at the target. According to the publication number: CN213207060U, a laser level is disclosed, including a level body and a tripod bracket located at the bottom of the level body, the tripod bracket includes a base plate and three legs fixed to the bottom of the base plate, a sliding rod is provided on the base plate, the sliding rod is passed through the base plate and slides in a vertical direction; the sliding rod is provided with vertical teeth along its axial direction, and a lifting gear meshing with the vertical teeth is provided in the base plate; a rotating shaft is provided on the lifting gear, the rotating shaft is mounted in the base plate, one end of the rotating shaft is provided with an external thread, and a tightening nut is provided on the rotating shaft; the tightening nut is threadedly connected to the external thread, and the tightening nut is against the side wall of the base plate. By tightening the nut, a pre-tightening force is applied to the rotating shaft, thereby fixing the lifting gear. This application has the effect of reducing the measurement error caused by the vertical gear sliding down, but the above technology still has some defects. For example, the existing level needs to be fixed with bolts when it is installed with the bracket. After long-term use, it is easy for the bolt to loosen and cause the level to fall off. The practicality is poor and needs to be improved. Utility Model Content

By setting the mounting plate 6, the mounting slot 7, the limit plate 8, the protrusion 9, the card plate 10, the card slot 11 and the limit pad 12, a better use effect is achieved. During use, the mounting plate 6 is first placed on the bracket, and then the mounting plate 6 is firmly fixed through the mounting slot 7. At this time, the bottom plate 1 is aligned with the card slot 11 inside the card plate 10 and then pushed into the inside of the card plate 10. When the bottom plate 1 completely slides into the inside of the card plate 10 through the card slot 11, the limit pad 12 can firmly clamp the bottom plate 1 in the inside of the card plate 10, so that The support rods 2 are evenly distributed on the top of the base plate 1, and the mounting plate 6 is slidably connected to the base plate 1, which makes it easier for the mounting plate 6 to slide and prevents the mounting plate 6 from being stuck by the base plate 1 during use, causing the mounting plate 6 to be unable to slide further. The mounting grooves 7 are evenly distributed on the top of the mounting plate 6, and the limit plate 8 is slidably connected to the base plate 1, which makes it easier for the limit plate 8 to slide and prevents the limit plate 8 from being stuck.

[0025] Embodiment 2

[0026] See also Figure 1-35. The interior of the irradiation port 5 is slidably connected with an inner plate 13. A protective cover 14 is fixedly installed on the right side of the inner plate 13. A cushion 15 is fixedly installed on the inner wall of the protective cover 14, which is more convenient for protecting the irradiation port 5 when not in use. When not in use, first pinch the protective cover 14 and correspond to the protective cover 14 and then pull it to the left, so that the protective cover 14 slides to the left on the surface of the irradiation port 5. When the inner wall of the protective cover 14 contacts the right side of the irradiation port 5, the inner plate 13 slides into the interior of the irradiation port 5, and then the cushion 15 can cover the protective cover 1 4 is firmly stuck on the surface of the irradiation port 5, so as to prevent the irradiation port 5 from being damaged due to being bumped when not in use. The protective cover 14 is slidably connected to the irradiation port 5, and the soft pad 15 is evenly distributed on the inner wall of the protective cover 14. The soft pad 15 is slidably connected to the irradiation port 5, which makes it easier for the protective cover 14 and the soft pad 15 to slide, and avoids the situation that the protective cover 14 and the soft pad 15 are stuck by the irradiation port 5 during use, resulting in the protective cover 14 and the soft pad 15 being unable to continue sliding.

[0027] Working principle: when in use, first place the mounting plate 6 at the required position, and then fix the mounting plate 6 firmly through the mounting groove 7, and at this time the limit plate 8 will clamp the fixing screws to prevent the fixing screws from loosening and falling off during long-term use. When the mounting plate 6 is firmly fixed, you can pinch the level body 3 and use the support rod 2 to match the bottom plate 1 to the upper slot 11, and push it toward the inside of the card board 10, so that the bottom plate 1 can slide inward on the surface of the card board 10 through the slot 11. When the bottom plate 1 completely slides into the inside of the card board 10, the limit pad 12 at the top of the protrusion 9 can firmly clamp the bottom plate 1 in the inside of the card board 10, and then the staff can observe through the observation hole 4 and the irradiation port 5, and when not in use When in use, pinch the level body 3 and pull it upwards first, so that the bottom plate 1 slides upward between the limit pad 12 and the card plate 10. At this time, the right side of the bottom plate 1 slides out of the inside of the limit pad 12, and then pulls it backwards to make the bottom plate 1 slide out of the inside of the card plate 10 through the card slot 11, so that the bottom plate 1 completely slides out of the top of the protrusion 9 for storage, and before storage, pinch the protective cover 14 corresponding to the upper irradiation port 5 and then pull it to the left, so that the protective cover 14 slides to the left on the surface of the irradiation port 5. When the inner wall of the protective cover 14 contacts the right side of the irradiation port 5, the inner plate 13 is firmly stuck in the inside of the irradiation port 5, and the protective cover 14 is firmly stuck on the surface of the irradiation port 5 by the soft pad 15, thereby protecting the irradiation port 5.
