Description

Technical Field

[0001] This utility model relates to the field of land surveying instrument technology, specifically a leveling bracket for a land surveying instrument with an adjustment structure. Background Technology

[0002] Land surveying refers to the process of using computer technology, optoelectronic technology, network communication technology, space science, and information science as a foundation, and Global Positioning System (GPS), Remote Sensing (RS), and Geographic Information System (GIS) as core technologies to obtain graphic and location information reflecting the current state of the ground by measuring existing feature points and boundaries. This information is then used for planning and design of engineering construction and administrative management. Land surveying requires the use of a land surveying instrument, which in turn requires a leveling support frame for support.

[0003] In the prior art, patent CN219036024U discloses a leveling bracket for a land surveying instrument, belonging to the field of surveying instrument bracket technology. It includes a base plate, an internally threaded tube fixedly connected to the top of the base plate, an externally threaded post threaded onto the internally threaded tube, a rotating seat fixedly connected to the top of the externally threaded post, a rotating plate rotatably connected to the top of the rotating seat, a fixing mechanism provided on the top of the rotating plate, a level provided on the top of the rotating plate, and multiple casters fixedly installed on the bottom of the base plate.

[0004] While the above-mentioned solution offers many advantages, it also has the following drawbacks: Currently, to increase the stability of the land surveying instrument leveling bracket during placement, multiple threaded rods are used to adjust the corresponding screws. These screws are inserted into the soil to improve the stability of the land surveying instrument leveling bracket. However, this structure requires manual adjustment of each screw individually, and the number of adjustments is relatively large (staff members need to tighten each threaded rod individually, and during storage, each threaded rod also needs to be reversed). This method is time-consuming and labor-intensive, making the support and installation of the land surveying instrument leveling bracket very troublesome, and thus reducing the practicality of the land surveying instrument leveling bracket. Utility Model Content

[0005] The purpose of this utility model is to provide a leveling bracket for a land surveying instrument with an adjustable structure, so as to solve the problem of low practicality of the existing land surveying instrument leveling brackets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leveling bracket for a land surveying instrument with an adjustable structure, comprising a base plate, a support column fixedly mounted on the upper part of the base plate, a support mechanism and a fixing mechanism mounted on the top of the support column, multiple universal wheels fixedly mounted on the bottom of the base plate, and a circumferentially arrayed sliding groove on the upper part of the base plate, in which a nail rod is slidably mounted, an external thread is provided on the outer side of the support column, and a threaded ring is threaded onto the support column through the external thread, a rotating ring is rotatably connected to the bottom of the threaded ring, and an inclined rod is fixedly connected between the rotating ring and the nail rod.

[0007] Preferably, the nail rod includes an outer tube that is slidably disposed in the cavity of the groove. One side of the outer tube is fixedly connected to one end of the inclined rod. A square groove is opened at the bottom of the outer tube. A square rod is slidably disposed in the cavity of the square groove. A threaded groove is opened at the top of the square rod. A threaded rod is threaded in the threaded groove. The threaded rod is rotatably connected to a rotating hole formed on the top wall of the square groove.

[0008] Preferably, a stop block is fixedly connected to the bottom of the square rod, and a pointed rod is fixedly provided at the bottom of the stop block.

[0009] Preferably, the support mechanism includes an externally threaded column, the top of which has a groove, the externally threaded column slides within the groove cavity, and a threaded tube is threadedly sleeved on the outer side of the externally threaded column, the threaded tube being rotatably connected to the top of the support column, and a rotating assembly being rotatably provided at the top of the externally threaded column.

[0010] Preferably, a limiting rod is fixedly installed on the bottom wall inside the column groove, and a limiting groove is opened at the bottom end of the external threaded column. The limiting rod slides in the cavity of the limiting groove. The vertical cross section of the limiting rod is a square structure, and the vertical cross section of the limiting groove is a square cavity.

[0011] Preferably, the rotating assembly includes a first turntable fixed to the top of the external threaded column, the upper part of the first turntable having a rotating groove, a worm gear and a worm being rotatably connected to each other on the inner wall of the rotating groove, a second turntable being fixedly disposed at the top of the worm gear, and a first knob being fixedly connected to the end of the worm.

[0012] Preferably, two rollers are rotatably connected to one side of the base plate.

[0013] Preferably, a handle is fixedly provided on the side of the first turntable away from the roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application sets up a threaded ring and a rotating ring, and uses a diagonal bar to fix each nail rod to the rotating ring. During use, only the height of the rotating ring needs to be adjusted to simultaneously drive each nail rod to extend and insert into the soil. This device is simple to operate and convenient to use, and can effectively improve the practicality and ease of use of the land surveying instrument leveling bracket.

[0016] 2. By setting up an outer tube and a square rod, this application can hide the threaded rod, avoiding problems such as corrosion and rust caused by the threaded rod being exposed to the outside and too close to the ground for a long time. This increases the service life of the nail rod. While adjusting the raising and lowering of each nail rod together, the length of each nail rod can also be adjusted individually. This allows for adjustment of the nail rod length according to the uneven ground on site, thus improving the applicability of the land surveying instrument leveling bracket.

[0017] 3. This application replaces the fixing bolts and threaded holes used in the prior art by setting a worm gear and using the self-locking method of the worm gear. Therefore, it can avoid the limitation of the position of the threaded hole and improve the range and applicability of the horizontal angle adjustment of the second turntable or land surveying instrument. At the same time, only the worm gear needs to be rotated, and no other fixing structure is required. Therefore, it can effectively improve the convenience of using the leveling bracket of the land surveying instrument.

[0018] 4. By setting up rollers and handles, this application allows staff to tilt the land surveying instrument leveling bracket and then push and pull it to move it. This increases the applicability of the land surveying instrument leveling bracket to different sites (such as moving it on uneven ground by pushing and pulling a suitcase), thus effectively improving the convenience of moving the land surveying instrument leveling bracket.

[0028] like Figure 4 and Figure 5 As shown, the nail rod 5 includes an outer tube 501 that is slidably disposed in the cavity of the groove. One side of the outer tube 501 is fixedly connected to one end of the inclined rod 8. A square groove 502 is opened at the bottom of the outer tube 501. A square rod 503 is slidably disposed in the cavity of the square groove 502. A threaded groove is opened at the top of the square rod 503. A threaded rod 504 is threadedly disposed in the threaded groove. The threaded rod 504 is rotatably connected to a rotating hole formed on the top wall of the square groove 502.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, a stop block 9 is fixedly connected to the bottom of the square rod 503, and a pointed rod 10 is fixedly installed at the bottom of the stop block 9.

[0030] like Figure 6 As shown, the support mechanism 3 includes an external threaded column 301. The top of the support column 2 is provided with a column groove. The external threaded column 301 slides in the cavity of the column groove. A threaded tube 302 is threaded on the outer side of the external threaded column 301. The threaded tube 302 is rotatably connected to the top of the support column 2. A rotating component 4 is rotatably provided at the top of the external threaded column 301.

[0031] like Figure 6 As shown, a limiting rod 12 is fixedly installed on the bottom wall inside the column groove. A limiting groove is opened at the bottom end of the external thread column 301. The limiting rod 12 slides in the cavity of the limiting groove. The vertical cross section of the limiting rod 12 is a square structure, and the vertical cross section of the limiting groove is a square cavity.

[0032] like Figure 2 and Figure 3 As shown, the rotating assembly 4 includes a first turntable 401 fixed to the top of the external threaded column 301. A rotating groove is provided on the upper part of the first turntable 401. A worm wheel 402 and a worm 403 that are meshed with each other are rotatably connected on the inner wall of the rotating groove. A second turntable 404 is fixedly provided at the top of the worm wheel 402. A first knob is fixedly connected to the end of the worm 403.

[0033] Specifically, two support frames are installed on the upper part of the second turntable 404, and a two-way screw is rotatably connected between the two support frames. Two extrusion plates are symmetrically arranged and threaded on the outer side of the two-way screw. The extrusion plates slide on the upper part of the second turntable 404, and the land surveying instrument is clamped between the two extrusion plates. The second turntable 404 is also equipped with multiple bubble levels. The bubble levels can be used to understand the level of the second turntable 404 and make corresponding adjustments.

[0034] The support frame, double-acting screw, extrusion plate, bubble level and land surveying instrument are all existing technical structures and equipment. Their specific forms, usage methods and installation methods are not described in detail in this application.

[0035] like Figure 1 and Figure 2 As shown, two rollers 13 are rotatably connected to one side of the base plate 1.

[0037] Working principle: Place the base plate 1 in the designated position, then rotate the threaded ring 6. The threaded ring 6 drives the rotating ring 7 to descend, and the rotating ring 7 drives each nail rod 5 to slide in the corresponding groove, so that the tip rod 10 at the bottom of the nail rod 5 is inserted into the soil, thereby completing the stable installation of the land surveying instrument leveling bracket.

[0038] When encountering uneven ground, the corresponding threaded rod 504 can be rotated according to the terrain, and the threaded rod 504 can be used to drive the square rod 503 to slide in the cavity of the square groove 502. This increases the distance between the pointed rod 10 and the outer tube 501, so that the pointed rod 10 can be inserted into the soil. If the soil is too hard, the position of the pointed rod 10 can also be adjusted by the body cavity, and then the pointed rod 10 can be inserted into the soil by hand or foot.

[0039] When the height of the land surveying instrument needs to be adjusted, the threaded tube 302 can be rotated, and the threaded tube 302 will drive the rotating component 4 to rise and fall using the external threaded column 301;

[0040] When adjusting the horizontal angle of the land surveying instrument, the worm gear 403 can be rotated. The worm gear 403 then uses the worm wheel 402 to drive the second turntable 404 to rotate on the first turntable 401, thereby adjusting the horizontal angle of the land surveying instrument on the second turntable 404.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
