[0004] Patent application publication number CN 217463794 U discloses a rangefinder for topographic surveying. A telescopic rod stabilizes the angles between the three support legs, allowing the support legs 302 to adapt to a wide range of terrain environments and various uneven terrains. This ensures that the relative angle between the first and second platforms remains constant, thereby ensuring the levelness of the first platform. By adjusting the leveling member, the first platform is always kept in a horizontal position, thereby ensuring that the rangefinder remains horizontal.

During the use of the above-mentioned rangefinder, the platform assembly needs to be supported by the first pointed cone at the upper end of the cylinder, and the cylinder is threadedly installed at the upper end of the column, and the cylinder and the column are provided in multiple groups. During the process of supporting by the first pointed cone, the multiple groups of cylinders need to be rotated in sequence, and the platform assembly needs to be kept stationary during the rotation process, which increases the complexity of the horizontal adjustment of the rangefinder and brings inconvenience to the horizontal adjustment of the instrument.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original rangefinder structure. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In a specific embodiment, Figure 1-Figure 2 As shown, the basic use process of the laser rangefinder is disclosed;

[0030] A mounting base 1 and a support leg 2 rotatably mounted at the lower end of the mounting base 1;

[0031] A fixed shaft 3 is fixedly mounted on the upper end of the mounting base 1, and a mounting plate 4 is fixedly mounted on the upper end of the fixed shaft 3, and a fixed base 5 is rotatably mounted on the upper end of the mounting plate 4, two sets of horizontal tubes 6 are nested and mounted on the outer side of the fixed base 5, and a laser instrument body 7 and a handle assembly 9 are fixedly mounted on the upper end of the fixed base 5, and an objective lens 8 is fixedly mounted on the outer side of the laser instrument body 7;

[0032] When using the laser rangefinder for geological surveying, it is necessary to place the laser rangefinder at the required position and make the support legs 2 support the laser rangefinder. Then, the laser rangefinder can be quickly supported and adjusted so that the laser instrument body 7 is in a horizontal state. At the same time, the shielding plate 20 can be pushed to move so that the shielding plate 20 is located at the upper end of the objective lens 8 to avoid the influence of sunlight and rain on the objective lens 8, thereby ensuring the accurate use of the laser rangefinder.

[0033] In one specific embodiment, Figures 1-4 As shown, the process of the laser rangefinder performing stable level adjustment is disclosed;

[0034] The upper end of the mounting seat 1 is provided with an adjustment structure for controlling the fixing seat 5 to maintain a horizontal level.

[0035] The adjustment structure includes a rotating cylinder 10 and a telescopic rod 11, wherein the rotating cylinder 10 is threadedly mounted on the outside of the fixed shaft 3, the telescopic rod 11 is fixedly mounted on the lower end of the mounting plate 4, and a lifting plate 12 is fixedly mounted on the lower end of the telescopic rod 11;

[0036] A fixing rod 13 is fixedly mounted on the upper end of the lifting plate 12, and a sealing member 14 is fixedly mounted on the upper end of the fixing rod 13, and the lower end surface of the lifting plate 12 is located at the upper end surface of the rotating cylinder 10;

[0037] A fixing cylinder 15 is fixedly mounted on the upper end of the mounting plate 4, and a supporting cylinder 16 is slidably mounted inside the fixing cylinder 15. Support springs 17 are provided inside the supporting cylinder 16 and the fixing cylinder 15. At the same time, the upper end surface of the supporting cylinder 16 is in close contact with the lower end surface of the fixing seat 5.

[0038] An air hole 18 is formed inside the fixing tube 15 and the mounting plate 4 , and the air hole 18 is sealed to the sealing member 14 .

[0039] When using the laser rangefinder for geological surveying, it is necessary to adjust the laser instrument body 7 horizontally, and in this process, it is necessary to directly rotate the fixing base 5. The fixing base 5 rotates on the upper end of the mounting plate 4, which drives the laser instrument body 7 to rotate synchronously, changing the angle of the laser instrument body 7. In addition, the angle of the laser instrument body 7 can be observed through the two sets of horizontal tubes 6 during the rotation process.

[0040] During the process of adjusting the angle of the laser instrument body 7, the support cylinder 16 moves up and down inside the fixed cylinder 15, and during this process, the support spring 17 contracts and expands, and during this process, the air inside the support cylinder 16 and the fixed cylinder 15 enters and is discharged through the air hole 18. After the angle adjustment of the laser instrument body 7 is completed, the laser instrument body 7 needs to remain stationary.

[0041] At this time, the rotating cylinder 10 can be rotated and moved upward on the outside of the fixed shaft 3. The upward movement of the rotating cylinder 10 will cause the telescopic rod 11 to contract, and will drive the fixed rod 13 and the seal 14 to move upward. At this time, the seal 14 can be brought into contact with the air hole 18 and seal the air hole 18, thereby sealing the space between the fixed cylinder 15 and the supporting cylinder 16, limiting the fixed cylinder 15 and the supporting cylinder 16, and ensuring the stability of the horizontal support of the fixed seat 5 and the laser instrument body 7.

[0042] Based on the above embodiments, Figure 1-Figure 2 and Figure 5-Figure 6 As shown, the protection process of the rangefinder for the objective lens 8 is disclosed;

[0043] The upper end of the handle assembly 9 is provided with a motion structure for protecting the objective lens 8 from being affected by sunlight;

[0044] The motion structure includes a limit plate 19 and a shielding plate 20. The limit plate 19 is fixedly mounted on the upper end of the handle assembly 9, and the shielding plate 20 is slidably mounted inside the limit plate 19. The limit plate 19 and the shielding plate 20 are located on the side of the upper end of the laser instrument body 7 close to the objective lens 8.

[0045] The limiting plate 19 has equidistantly formed engaging grooves 21 therein. Two sets of engaging blocks 22 are slidably mounted therein. A return spring 23 is fixedly mounted on one end of the engaging block 22 close to the limiting plate 19 .

[0046] When using the geological surveying laser rangefinder, the shielding plate 20 can be pushed to slide inside the limiting plate 19, and the shielding plate 20 will drive the locking block 22 and the return spring 23 to move synchronously during the sliding process;

[0047] During this process, the engaging block 22 will be squeezed by the engaging groove 21 and move toward the inside of the shielding plate 20. During the movement of the engaging block 22, the return spring 23 will be squeezed and the return spring 23 will be contracted. When the shielding plate 20 stops moving, the contracted return spring 23 will expand and push the engaging block 22 to move outward. Thereafter, the engaging block 22 can be engaged with the engaging groove 21, thereby limiting the shielding plate 20 at this position, completing the protection process of the shielding plate 20 for the objective lens 8, effectively improving the use effect of the rangefinder and increasing the overall practicality.

[0048] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
