Description

Technical Field

[0001] The utility model relates to the technical field of surveying instruments, in particular to a housing area surveying instrument. Background Technique

[0002] A surveying instrument is a precision instrument integrating light, machinery and electricity, mainly used for the measurement and mapping of geospatial data, and instruments and devices for data acquisition, processing, output, etc. designed and manufactured for surveying operations. It is used for various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry instruments required for measurement work in the planning, design, construction, and operation management stages of engineering construction. However, there are still some deficiencies in the existing surveying instruments during use.

[0003] For example, a portable surveying instrument with the publication number CN220727813U. By setting a handle and a hanging strap, users can fix the surveying instrument body on the user's body through the hanging strap, reducing the burden on the arm and providing more stable support. By setting a support component and a binding strap, the measurement error caused by hand shaking or unstable support is reduced, and the binding strap can bind the three support components together during carrying to prevent shaking during carrying, thus facilitating carrying. However, during surveying, the staff needs to often move the surveying instrument from one place to another, which is rather troublesome and also easily causes the surveying instrument to be bumped. At the same time, the user adjusts the height of the surveying instrument according to their own situation. However, the existing adjustment method for height is not smooth enough, and the height of the surveying instrument cannot be adjusted arbitrarily, thus bringing limitations to the use of the surveying instrument body.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1: Please refer to Figures 1 - 8 As shown, the present utility model provides a technical solution: A housing area surveying instrument includes a surveying instrument body 1, a support base 2 is arranged outside the surveying instrument body 1, a guide rod 3 is fixedly connected to the bottom end of the support base 2, and a bottom plate 4 is arranged below the support base 2.

[0033] This technical solution utilizes the settings of the support base 2 and the bottom plate 4. When in use, first place the surveying instrument body 1 at a designated position, and adjust the height of the support base 2 according to the actual situation to ensure that the station is stable enough to prevent the instrument from moving during the measurement process, thus facilitating subsequent measurements.

[0034] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on the above Embodiment 1. In the existing surveying, staff often need to move the surveying instrument from one place to another, which is rather troublesome and also likely to cause the surveying instrument to be bumped. This technical solution is as Figures 1 - 5 shown, and discloses a protection mechanism for the surveying instrument. A straight groove 2001 is opened at the top end of the support base 2, a connecting rod 17 is slidably connected in the straight groove 2001, a connecting plate 18 is fixedly connected to the connecting rod 17, and a protection mechanism is fixedly connected to the bottom end of the connecting rod 17. A resisting plate 19 is movably connected in the connecting plate 18. An active rod 15 is movably connected inside the protection mechanism, and a grip 16 is fixedly connected to the top rod of the active rod 15; and a convex block 1501 is fixedly connected to the outer side of the active rod 15. Three groups of straight grooves 2001 are arranged in a circular array about the center point of the support base 2, and the support base 2 is in sliding fit with the connecting plate 18. A compression spring 1901 is connected between the connecting plate 18 and the resisting plate 19, and an elastic telescopic structure is formed between the connecting plate 18 and the resisting plate 19 through the compression spring 1901. One end of the resisting plate 19 is provided with an inclined surface. The protection mechanism includes a disc 9, a chute 9001, a threaded guide groove 9002, a slider 10, an extrusion block 11, and a protection baffle 12. The disc 9 is rotatably installed in a groove opened at the top end of the support base 2, and a protection baffle 12 is fixedly connected to the bottom end of the disc 9. A chute 9001 is opened on the upper surface of the disc 9, and a threaded guide groove 9002 is opened in the middle of the disc 9. The active rod 15 is movably arranged in the threaded guide groove 9002, and the convex block 1501 on the outer side of the active rod 15 is slidably connected to the threaded guide groove 9002. The slider 10 is slidably arranged in the chute 9001, and an extrusion block 11 is fixedly connected to the top end of the slider 10. The chute 9001 is arranged in an arc structure, and three groups of chutes 9001 are arranged in a circular array about the center point of the disc 9. The chute 9001 corresponds to the straight groove 2001, and the bottom end of the connecting rod 17 in the straight groove 2001 is fixedly connected to the top end of the extrusion block 11. The protection baffle 12 is arranged in an arc structure, and two protection baffles 12 are symmetrically arranged, and both protection baffles 12 are slidably connected to the support base 2. The protection mechanism further includes a first airbag 13 and a second airbag 14. The first airbag 13 is fixedly arranged in the support base 2, and three first airbags 13 are provided, and the first airbags 13 correspond to the extrusion blocks 11. The second airbag 14 is fixedly arranged on the opposite side of the inner wall of the support base 2, and the second airbag 14 is connected to the first airbag 13 through a pipeline.

[0035] In this technical solution, asFigure 1 and Figure 2 As shown, by using the settings of the protective baffle 12 and the first airbag 13, when the surveying instrument body 1 is carried, the protective baffle 12 will automatically open under the drive of the disc 9, thereby sealing the open opening on the support base 2 and protecting the surveying instrument body 1 from damage, and the disc 9 will drive the extrusion block 11 to move, so that the extrusion block 11 squeezes the first airbag 13, thereby transporting the gas in the first airbag 13 to the second airbag 14, so that the second airbag 14 expands and fits the surveying instrument body 1, providing all-round support and protection for the surveying instrument body 1, preventing the surveying instrument body 1 from being subjected to uneven impact force during movement or transportation, thereby reducing the risk of damage.

[0036] Its use is as Figures 3 - 5 The technical solution shown is that when the surveying instrument body 1 needs to be carried, the staff manually pulls the handle 16, and the handle 16 drives the movable rod 15 to move upward, so that the protrusion 1501 on the movable rod 15 slides along the threaded guide groove 9002, thereby driving the disc 9 to rotate, and the disc 9 drives the protective baffle 12 to rotate, so that the protective baffle 12 cooperates with the support seat 2 to protect the surveying instrument body 1, and at the same time the slider 10 slides along the slide groove 9001, thereby driving the extrusion block 11 to move, and the extrusion block 11 drives the straight groove 2001 to slide, thereby driving the connecting plate 18 to move, and the connecting plate 18 moves to Above the second rod body 21 after storage, the contact plate 19 in the connecting plate 18 will slide against the surface of the second rod body 21, and the contact plate 19 will squeeze the compression spring 1901 to contract, so that the compression spring 1901 squeezes the contact plate 19 to fit the second rod body 21 through the action of elastic force, thereby limiting the second rod body 21. At the same time, the extrusion block 11 will squeeze the first airbag 13 during the movement, so that the first airbag 13 will shrink, thereby transporting the gas stored therein to the second airbag 14 through the pipeline, so that the second airbag 14 will expand and fit the surveying and mapping instrument body 1, thereby providing secondary protection for the surveying and mapping instrument body 1.

[0037] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. The height of the surveying and mapping instrument is adjusted according to the user's own situation. However, the existing height adjustment method is not smooth enough, and the height of the surveying and mapping instrument cannot be adjusted at will, which brings limitations to the use of the surveying and mapping instrument body. In order to further solve this technical problem, this technical solution is as follows: Figures 6 - 8As shown in the figure, an adjustment mechanism of a surveying instrument is disclosed. A first rod body 20 is rotatably installed outside a support base 2. A second rod body 21 is slidably installed in a groove formed in the middle of the first rod body 20. A limiting groove 2101 is formed in the side wall of the second rod body 21. And a limiting component corresponding to the limiting groove 2101 is slidably connected to the side wall of the first rod body 20. The bottom end of a guide rod 3 is fixedly connected to a moving member 5. A threaded rod 6 is arranged in the moving member 5. A worm gear 7 is fixedly connected to the threaded rod 6. And a worm 8 cooperating with the worm gear 7 is rotatably installed in a groove formed in a bottom plate 4. The limiting component includes a limiting block 22 and an auxiliary spring 2201. The limiting block 22 is slidably arranged on the side wall of the first rod body 20 and corresponds to the limiting groove 2101. And a slope is formed at one end of the limiting block 22 close to the limiting groove 2101. The auxiliary spring 2201 is located in the groove formed in the first rod body 20. One end of the auxiliary spring 2201 is fixedly connected to the first rod body 20. And the other end of the auxiliary spring 2201 is fixedly connected to the limiting block 22. A plurality of limiting grooves 2101 are arranged at equal intervals. The worm gear 7 is rotatably arranged in the groove formed in the bottom plate 4 and meshes with the worm 8. And the threaded rod 6 at the bottom end of the worm gear 7 is in threaded connection with the moving member 5. Two guide rods 3 on the moving member 5 are symmetrically arranged. And both of the two guide rods 3 are slidably connected to the bottom plate 4.

[0038] In this technical solution, as Figure 6 shown, by arranging the worm gear 7 and the worm 8, when the worm 8 rotates, it meshes with and drives the worm gear 7 to rotate. Thus, the threaded rod 6 is driven to rotate by the worm gear 7. And under the threaded cooperation between the threaded rod 6 and the moving member 5, the height of the support base 2 is adjusted to adapt to different measurement requirements and improve the measurement accuracy.

[0039] It adopts the technical solution as Figure 7 and Figure 8 shown. First, when the surveying instrument body 1 needs to be installed, by rotating the first rod body 20, the first rod body 20 drives the second rod body 21 to rotate and open. And the tip of the second rod body 21 is inserted into the ground. When encountering an uneven road surface, by pulling the second rod body 21, the second rod body 21 slides out along the inner wall of the first rod body 20, so as to extend the second rod body 21 and make it contact with the ground. At the same time, the limiting block 22 will be inserted into the limiting groove 2101 under the elastic force of the auxiliary spring 2201 to prevent the second rod body 21 from loosening.

[0040] When the height of the support base 2 needs to be adjusted, by manually rotating the worm 8, the worm 8 meshes with and drives the worm gear 7 to rotate. Thus, the moving member 5 is driven to slide along the inner wall of the bottom plate 4. When the moving member 5 moves, it will drive the guide rod 3 to move. The guide rod 3 will drive the support base 2 to move, so as to adjust the height of the surveying instrument body 1.

[0041] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
