It has wide applications in many fields such as engineering construction, geospatial information, biomedicine, and environmental protection. The surveying instrument is one of the tools frequently used by the inventor in surveying work. When using a surveying instrument, it needs to be fixed with a bracket before surveying to ensure the stability of the instrument as a whole, so that surveyors can conduct surveys, measure the location, elevation, and dimensions of buildings, help architects and engineers design and plan building projects, and measure parameters such as the location, length, and slope of roads.

[0003] As indicated by announcement number CN220647332U, the device is a surveying instrument. It includes a surveying instrument body and a base located at the bottom of the surveying instrument body. The base is provided with mounting components for mounting the surveying instrument body. A fixing plate is fixedly connected to the bottom of the base. Positioning components are provided around the outer wall of the fixing plate. Support legs are rotatably connected around the bottom of the base.

[0004] The aforementioned device lacks a dedicated protective structure during use, which results in an inability to effectively disperse the impact force upon a fall, leading to damage to the internal components of the instrument. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing protective shell for a surveying instrument, in order to solve the problem mentioned in the background art that the existing device does not have a dedicated protective structure, which leads to the inability to effectively disperse the impact force when falling, resulting in damage to the internal components of the instrument.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing protective shell for a surveying instrument, a support platform, a connecting plate at the lower end of the support platform, and a shock-absorbing shell at the upper end of the support platform.

[0007] Also includes:

[0008] A shock absorber cylinder is disposed inside a shock absorber housing. Multiple shock absorber cylinders are provided, and one end of the outer surface of the shock absorber cylinder is connected to the inner wall of the shock absorber housing.

[0016] This invention incorporates a shock-absorbing cylinder, a compression spring, a limiting block, a moving rod, a clamping plate, and a shock-absorbing pad. When the protective shell is impacted, the compression spring absorbs and disperses the impact force, effectively reducing the vibration and damage to the surveying instrument caused by drops, thus protecting the precision components inside the instrument from damage. The shock-absorbing pad and shock-absorbing sponge further enhance the protective effect. These materials effectively absorb and disperse the impact force, reducing the damage to the surveying instrument caused by collisions or drops, achieving a protective effect for the surveying instrument. This solves the problem of traditional devices lacking a dedicated protective structure, which prevents effective dispersion of impact force during drops, thus causing damage to the internal components of the instrument.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-3 One embodiment of this utility model is a shock-absorbing protective shell for a surveying instrument, comprising a support platform 1, a connecting plate 2 at the lower end of the support platform 1, and a shock-absorbing shell 12 at the upper end of the support platform 1.

[0024] Also includes:

[0025] The shock absorber cylinder 15 is disposed inside the shock absorber housing 12. Multiple sets of shock absorber cylinders 15 are provided, and one end of the outer surface of the shock absorber cylinder 15 is connected to the inner wall of the shock absorber housing 12. A compression spring 16 is installed inside the shock absorber cylinder 15, and one end of the compression spring 16 is fixedly connected to one end inside the shock absorber cylinder 15. The other end of the compression spring 16 is connected to a limit movement structure 151.

[0026] After the surveying instrument is installed in the shock-absorbing housing 12, when it receives an impact force, the outer shock-absorbing housing 12 first contacts and absorbs part of the impact energy, reducing the direct impact on the internal surveying instrument. After the impact force is transmitted to the inside of the shock-absorbing housing 12, the multiple sets of shock-absorbing cylinders 15 set inside the shock-absorbing housing 12 begin to play a shock-absorbing role. When it is impacted, the compression spring 16 is compressed, absorbing and storing the impact energy. At the same time, it converts part of the energy into heat energy and dissipates it through its elastic deformation. When the compression spring 16 is compressed, the limiting movement structure 151 will move, thereby reducing the damage of the impact force to the surveying instrument.

[0027] Please see Figure 2 A fixing rod 3 is provided at the bottom of the connecting plate 2, and the fixing rod 3 is fixedly connected to the connecting plate 2. A mounting plate 4 is provided at the lower end of the fixing rod 3, and the mounting plate 4 is fixedly connected to the fixing rod 3. A movable wheel 5 is installed on the lower surface of the mounting plate 4.

[0028] Please see Figure 2 The limiting and moving structure 151 includes a limiting block 17. A moving rod 18 is provided at one end of the limiting block 17 and is fixedly connected to the limiting block 17. A clamping plate 19 is provided on the surface of the moving rod 18 and is fixedly connected to the moving rod 18. A shock-absorbing pad 20 is provided on the surface of the clamping plate 19 and is fixedly connected to the clamping plate 19. A shock-absorbing sponge 21 is provided inside the shock-absorbing housing 12 and is fixedly connected to the inner wall of the shock-absorbing housing 12. In use, the limiting block 17 moves along the inner wall of the shock-absorbing cylinder 16 and transmits the remaining impact force to the clamping plate 19 through the moving rod 18 fixedly connected to it. The clamping plate 19 on the surface of the moving rod 18 is in direct contact with the surveying instrument. The shock-absorbing pad 20 on it further absorbs and disperses the impact force, reducing damage to the surveying instrument. The shock-absorbing sponge 21 absorbs and disperses the energy generated by the displacement, playing an auxiliary role in shock absorption.
