[0029] As Figures 1-4As shown, the utility model provides a technical scheme: mounting seat 1 is the basic support structure of whole ranging device, and the limit groove 2 that opens close to both sides in its inside provides the guiding and limiting function for subsequent shock absorption buffer structure, and the limit sliding block 3 is closely fitted in the limit groove 2, and the connecting block 4 is integrally designed with the limit sliding block 3, and this integral structure guarantees the stability and integrity of connection, so that when the bottom cylinder 14 is subjected to external force, the connecting block 4 can drive the limit sliding block 3 to smoothly slide in the limit groove 2, avoids the situation of shaking or deviating from the track, and the bottom cylinder 14 is an important component of bearing laser range finder body 16, is connected with mounting seat 1 through this connecting mode, so that the overall structure is more stable and reliable, and also provides an effective force point for the shock absorption spring to work.

[0030] By the cooperation of limit groove 2 and limit sliding block 3, the movement direction of bottom cylinder 14 is limited, so that it can only move on a specific straight track, so that when subjected to vibration or impact, the irregular external force is converted into linear force along the direction of limit groove 2, and the shock absorption spring 18 is facilitated to carry out shock absorption operation.

[0031] The through groove provided in the inside bottom of mounting seat 1 provides a movement space for connecting column 17, the connecting column 17 penetrates through the through groove and is connected with the outside, the shock absorption spring 18 is sleeved on the connecting column 17 and the two ends are fixed with the bottom cylinder 14 and the inside bottom of mounting seat 1 respectively, when the outside produces vibration or impact, the bottom cylinder 14 is subjected to upward or downward force, due to the limitation of connecting column 17, the shock absorption spring 18 will be compressed or stretched, the shock absorption spring 18 is according to Hooke's law, and the elastic force generated is proportional to the deformation, in this process, the spring absorbs vibration energy through its elastic deformation and converts it into elastic potential energy, when the external force disappears, the elastic potential energy is released, so that the bottom cylinder 14 returns to the original equilibrium position, thereby effectively reducing the vibration energy transmitted to the laser range finder body 16, and protecting the internal precision components.

[0032] Based on the elastic deformation characteristics of spring, the impact force generated by external vibration is offset and absorbed through the expansion and contraction of shock absorption spring 18, plays the role of shock absorption, prevents the internal components of laser range finder from being damaged or connection loosening due to sudden vibration.

[0033] The first hinge 19 installed on the wall around the mounting base 1 enables the support leg 20 to rotate flexibly relative to the mounting base 1, and in different use scenarios, the angle of the support leg 20 can be adjusted to adapt to different terrains or installation requirements, and the second hinge 21 at the connection of the support leg 20 further increases the flexibility of the support structure, and the support base 22 installed at the bottom increases the contact area with the ground, improving the stability of the entire device when placed, for example, on uneven ground, by adjusting the angle of the support leg 20, the mounting base 1 can be kept horizontal, ensuring the measurement accuracy of the laser range finder.

[0034] By utilizing the rotatable characteristics of the hinge, the angle of the support leg 20 in different planes can be adjusted to adapt to various complex ground environments, and the support base 22 reduces the unit area pressure by increasing the contact area to improve the overall stability and provide a stable measurement platform for the laser range finder.

[0035] The slot on the outer surface of the connecting sleeve 15 cooperates with the limiting column 13 in the quick release assembly to realize the quick connection and disassembly of the laser range finder body 16 and the connecting sleeve 15, the mounting cavity 6 in the mounting block 5 provides installation space for other components of the quick release assembly, the partition plate 7 separates the mounting cavity 6 into different areas, the limiting seat 8 is installed at the connection of the partition plate 7, and the plurality of sliding grooves 9 opened in the limiting seat 8 provide precise sliding tracks for the sliding block 10, the sliding block 10 is fixedly connected with the sliding plate 11, so that the sliding plate 11 can stably move horizontally under the guidance of the limiting seat 8, and the compression spring 12 is installed between the sliding plate 11 and the partition plate 7, when it is necessary to install the laser range finder body 16, the connecting structure at the bottom thereof is aligned with the connecting sleeve 15 and inserted, at this time, the limiting column 13 is pressed inward by the inner wall of the connecting sleeve 15, and the compression spring 12 is compressed, when the laser range finder body 16 is installed in place, the limiting column 13 is clamped into the slot of the connecting sleeve 15 under the elastic force of the compression spring 12, and the fixing is completed; when disassembly is needed, the limiting column 13 is pressed to overcome the elastic force of the compression spring 12, so that the limiting column 13 is separated from the slot, and the laser range finder body 16 can be taken out.

[0036] By utilizing the elastic force of the compression spring 12 and the cooperation of the limiting column 13 and the slot, the quick locking and unlocking of the laser range finder body 16 is realized, which facilitates the installation personnel to quickly switch the measurement mode according to the actual demand while ensuring the stability of the connection.

[0037] Installation preparation: place the mounting base 1 in a suitable position, adjust the angle of the support leg 20 according to the ground conditions, make the support base 22 stably contact the ground through the first hinge 19 and the second hinge 21, and ensure that the mounting base 1 is in a horizontal and stable state.

[0038] Laser range finder installation: the connecting structure at the bottom of the laser range finder body 16 is aligned with the connecting sleeve 15, and is inserted vertically downward, the limiting column 13 of the quick release assembly is extruded to the inside by the inner wall of the connecting sleeve 15 during the insertion process, the compression spring 12 is compressed, when inserted in place, the limiting column 13 is clamped into the slot of the connecting sleeve 15 under the elastic force of the compression spring 12, the fixed connection of the laser range finder body 16 and the support is completed.

[0039] Measurement operation: turn on the laser range finder body 16 to measure the distance, if vibration or impact is encountered during measurement, the buffer spring 18 inside the mounting seat 1 absorbs and disperses the vibration energy through the cooperation of the limiting slot 2 and the limiting block 3, and protects the internal precision components of the laser range finder body 16.

[0040] Dismounting and switching: when the laser range finder body 16 needs to be removed from the support for handheld measurement or storage and transportation, press the limiting column 13 of the quick release assembly, overcome the elastic force of the compression spring 12 to make it disengage from the slot of the connecting sleeve 15, then take out the laser range finder body 16 upward, realize quick dismounting, and the measurement mode can be flexibly switched according to actual needs.

[0041] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
