[0001] This utility model relates to the field of geographic surveying and mapping technology, specifically to a vertical geographic surveying and mapping device that is easy to fix. Background Technology

[0002] Geographic surveying is a science and technology field that involves collecting, analyzing and displaying geographic information. It helps people understand the geographic environment and spatial changes by measuring and representing various features of the Earth's surface and their spatial relationships. Geographic surveying uses a variety of technologies and methods, including ground surveying, aerial photography, remote sensing technology and geographic information systems. The most commonly used tool in geographic surveying is the surveying instrument.

[0003] Existing surveying instruments rely on supports to be used on the surveying site during surveying. If the support is accidentally tilted and falls during use, the surveying instrument will come into direct contact with the ground and be damaged. Therefore, the safety of the surveying instrument during use is relatively low. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical geographic surveying device that is easy to fix, which solves the problem that existing surveying instruments rely on supports for use on the surveying site. If the support is accidentally tilted and falls during use, the surveying instrument will directly contact the ground and impact, which will directly damage the surveying instrument and result in low safety during use.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0006] Support frame;

[0007] A protective component is disposed above a support frame. A surveying instrument is disposed above the protective component. The protective component includes a mounting base. An annular groove is formed inside the mounting base. Multiple through grooves are formed below the annular groove. Multiple hollow fan-shaped arc plates slide inside the annular groove. Each of the multiple hollow fan-shaped arc plates has a groove inside. An inner arc plate slides inside each of the multiple hollow fan-shaped arc plates. A gravity ball is fixed below each of the multiple inner arc plates by ropes. The gravity ball extends through the through grooves to the bottom of the mounting base.

[0008] Preferably, the mounting base has an internal mounting cavity and an upper mounting groove. A fixing component is provided inside the mounting cavity, which is used to quickly connect the surveying instrument to the mounting base.

[0009] Preferably, the mounting cavity has two limiting grooves inside, and through holes are provided on both sides above the mounting cavity. The fixing assembly includes a sliding plate that slides inside the mounting cavity and two locking plates that rotate inside the mounting cavity. Two connecting rods are fixed below the sliding plate, and the two connecting rods extend into the two limiting grooves respectively. A lead screw rotates below the sliding plate, and one end of the lead screw extends to the bottom of the mounting base. A hollow plate is fixed to one end of each of the two locking plates. A driving arm passes through the interior of each of the two hollow plates, and the two driving arms are fixed above the sliding plate.

[0010] Preferably, the support frame includes a support base, which is fixed below the mounting base. Three rotating frames are rotatably mounted below the support base.

[0012] Preferably, the through groove and the groove body are on the same vertical plane.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By using the gravity ball to maintain its vertical orientation towards the ground, when the device tilts, the inner arc plate connected to it can slide out from the hollow fan-shaped arc plate. As the device tilts, the inner arc plate also causes the hollow fan-shaped arc plate to slide out of the annular groove. The hollow fan-shaped arc plate and the inner arc plate will protect the surveying instrument around it, preventing the surveying instrument from being damaged by impact with the ground and improving the safety of the surveying instrument.

[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: a vertical geographic surveying device that is easy to fix, such as... Figure 1-4 As shown, it includes a support frame 1 and a protective component 2. The protective component 2 is disposed above the support frame 1. The support frame 1 includes a support base 11, which is fixed below the mounting base 21. Three rotating frames 12 are rotatably disposed below the support base 11. Support legs 13 slide inside each of the three rotating frames 12. One end of each of the three rotating frames 12 is provided with a tightening screw 14, which is used to tighten the position of the support legs 13, thereby fixing the length between the rotating frames 12 and the support legs 13. One end of the support legs 13 is provided with a pointed cone plate 15.

[0023] A surveying instrument 3 is installed above the protective component 2. The protective component 2 includes a mounting base 21. An annular groove 22 is opened inside the mounting base 21. Multiple equally spaced through grooves 23 are opened below the annular groove 22. Multiple equally spaced hollow fan-shaped arc plates 24 slide inside the annular groove 22. The number of hollow fan-shaped arc plates 24 and through grooves 23 is the same, and each through groove 23 is located in the middle of each hollow fan-shaped arc plate 24. Each hollow fan-shaped arc plate 24 has a groove 25 inside. The through grooves 23 and the grooves 25 are on the same vertical plane. Each hollow fan-shaped arc plate 24 has an inner arc plate 26 sliding inside. Each inner arc plate 26 is fixed with a gravity ball 27 by a rope below. The gravity ball 27 extends through the through groove 23 to the bottom of the mounting base 21.

[0024] The mounting base 21 has a mounting cavity 4 inside, and a mounting groove 5 is provided on the top of the mounting base 21. The size of the mounting groove 5 is adapted to the size of the base of the surveying instrument 3. A fixing component 6 is provided inside the mounting cavity 4. The fixing component 6 is used to quickly connect the surveying instrument 3 to the mounting base 21. Two limiting grooves 7 are provided inside the mounting cavity 4. Through holes 8 are provided on both sides of the top of the mounting cavity 4. The fixing component 6 includes a sliding plate 61 that slides inside the mounting cavity 4 and two locking plates 62 that rotate inside the mounting cavity 4. The two locking plates 62 extend through the two through holes 8 to the top of the mounting base 21. Two locking holes are provided above the base, corresponding to and adapted to one end of the locking plate 62. Two connecting rods 63 are fixed below the sliding plate 61. The two connecting rods 63 extend into the interior of the two limiting grooves 7 respectively to limit the lifting trajectory of the sliding plate 61. A lead screw 64 rotates below the sliding plate 61. One end of the lead screw 64 extends to the bottom of the mounting base 21 and the support base 11. The lead screw 64 is threaded at the point where it passes through the mounting base 21. A hollow plate 65 is fixed to one end of each of the two locking plates 62. A drive arm 66 passes through the interior of each of the two hollow plates 65. The two drive arms 66 are fixed above the sliding plate 61.

[0025] In use, place the base of the surveying instrument 3 into the mounting slot 5 and rotate the lead screw 64. The lead screw 64 rises, causing the sliding plate 61 to rise. The sliding plate 61 then drives the two drive arms 66 to rise. The two drive arms 66 slide in the two hollow plates 65 respectively and push the two hollow plates 65 to rise. The two hollow plates 65 respectively drive the two clamping plates 62 to deflect in the direction of the surveying instrument 3 until the clamping plates 62 are locked in the corresponding clamping holes. The surveying instrument 3 can then be installed and fixed. Disassembly is also convenient in the later stage. Just rotate the lead screw 64 in the opposite direction.

[0026] During the use of the surveying instrument 3, if the device accidentally falls in one direction, the gravity ball 27 will maintain its vertical orientation towards the ground due to its own weight. Thus, when the device tilts, it will cause the inner arc plate 26 connected to it to slide out of the hollow fan-shaped arc plate 24. As the device tilts, the inner arc plate 26 will cause the hollow fan-shaped arc plate 24 to slide out of the annular groove 22. The hollow fan-shaped arc plate 24 and the inner arc plate 26 will protect the surveying instrument 3 around it, preventing the surveying instrument 3 from being damaged by impact with the ground, thereby improving the safety of the surveying instrument 3.

[0027] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
