Description

Technical Field

[0001] This utility model relates to the field of geodetic surveying technology, specifically to an improved structure for a geodetic tripod. Background Technology

[0002] Geodetic surveying refers to the measurement, collection, and mapping of the shape, size, spatial location, and attributes of natural geographical elements or artificial structures on the Earth's surface. It involves instruments and devices designed and manufactured for data acquisition, processing, and output in surveying operations. Various instruments are used in engineering construction planning, design, construction, and management for surveying work, including those for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry. A surveying tripod is a support structure used to support surveying instruments during the surveying process. A tripod is a common support component, using three legs to provide a stable support platform. The use of tripods often involves issues of carrying and transportation; therefore, portability is a crucial consideration in tripod design.

[0003] A search revealed a portable geodetic tripod, application number CN201922325148.3. When using this tripod, its lower part often needs to be inserted into the soil to improve its stability. This causes a large amount of mud or dirt to easily adhere to the surface of the lower part of the tripod. After use, this mud or dirt may scatter during movement, polluting the surrounding environment (such as car trunks, the interior of work vehicles, or other storage spaces). Due to the mud or dirt adhering to the tripod surface, workers need to be particularly careful when carrying it to avoid contaminating other items or equipment. This makes carrying and storing the tripod inconvenient, especially when frequent movement is required, causing inconvenience for workers. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model proposes an improved structure for a geodetic tripod to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An improved structure for a geodetic tripod includes a tripod mounting platform and a mounting plate fixed to the bottom of the tripod mounting platform, and further includes:

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] An improved geodetic tripod structure according to this specific implementation method, such as... Figure 1-6 As shown, the device includes a tripod mounting platform 1, the top of which is used to mount a geodetic instrument. The surface of the top of the tripod mounting platform 1 has mounting slots. The bottom of the tripod mounting platform 1 is fixed with a mounting plate 2. Tripod legs 3 are hinged to the four sides of the bottom of the mounting plate 2. Positioning holes 4 are opened on the upper surface of the tripod legs 3 on both the left and right sides. Positioning cones 5 are fixed to the bottom of the tripod legs 3. A lifting ring 6 is provided below the tripod mounting platform 1. A bellows cover 7 is fixed to the top surface of the lifting ring 6. The top of the bellows cover 7 is fixedly connected to the bottom of the tripod mounting platform 1. Movable plates 8 are provided on both the left and right sides of the lifting ring 6. Positioning structures 9 are movably connected to the surface of the movable plates 8.

[0027] The positioning structure 9 includes a threaded rod 91, a knob 92, a movable piece 93, a positioning rod 94, a positioning block 95, and a positioning groove 96. The threaded rod 91 is threadedly connected to one side of the movable plate 8. The knob 92 is fixed to one end of the threaded rod 91. The movable piece 93 is rotatably connected to the end of the threaded rod 91 away from the knob 92. The positioning rod 94 is fixed to the surface of the movable piece 93. The positioning block 95 is sleeved on the surface of the positioning rod 94 and fixedly connected to the positioning rod 94. The positioning groove 96 is formed on the top of the positioning block 95. The positioning rod 94 is slidably connected to the inner wall of the positioning hole 4. The positioning cone 5 is slidably connected to the inner wall of the positioning groove 96. When the operator rotates the knob 92, the knob 92 will drive the threaded rod 91 to rotate, causing the threaded rod 91 to push... The movable piece 93 moves towards the tripod leg body 3, causing the positioning rod 94 to insert into the positioning holes 4 on the surface of the tripod leg body 3 on both sides, thus completing the height positioning of the lifting ring 6. When the operator pulls down the lifting ring 6, causing the positioning block 95 to move below the positioning cone 5, the knob 92 is rotated, which causes the positioning rod 94 to move the positioning block 95 below the positioning cone 5. After aligning the positioning groove 96 with the bottom of the positioning cone 5, the positioning cone 5 can be inserted into the positioning groove 96 on the surface of the positioning block 95, thereby repositioning the lifting ring 6. The accordion cover 7 above the lifting ring 6 extends to cover the entire tripod, preventing dirt or grime on the tripod surface from contaminating the surrounding area.

[0028] Guide rods 10 are fixed to the front and back of one side surface of the movable piece 93, and the guide rods 10 pass through the movable plate 8 and are slidably connected to the movable plate 8. The guide rods 10 can guide the movable piece 93, so that the positioning rod 94 can only move horizontally left and right.

[0029] Magnetic blocks 11 are fixed on both the left and right sides of the lifting ring 6. The movable plate 8 is made of metal and works in conjunction with the magnetic blocks 11. The upper part of the movable plate 8 is hinged to the surface of the lifting ring 6. When the operator unfolds the tripod leg body 3 below, the movable plates 8 on both sides can be flipped, thereby changing the movable plate 8 from a vertical state to a horizontal state, so that the magnetic blocks 11 are attached to the surface of the movable plate 8. The magnetic blocks 11 attract the movable plate 8, thereby fixing the movable plate 8 and preventing it from colliding with the positioning rod 94 when the tripod leg body 3 is unfolded.

[0030] Limiting rods 12 are fixed on both the front and rear sides of the bottom of the tripod mounting platform 1. Limiting holes 13 are opened on both the front and rear sides of the top of the lifting ring 6. The limiting rods 12 are engaged with the inner walls of the limiting holes 13. When the lifting ring 6 rises, the limiting rods 12 will be inserted into the limiting holes 13 on the surface of the lifting ring 6. The lifting ring 6 is repositioned by the limiting rods 12 and the limiting holes 13. When the movable plates 8 on the left and right sides are flipped, the limiting rods 12 can continue to position the lifting ring 6 to prevent the lifting ring 6 from sliding down.

[0031] The accordion cover 7 is made of nylon fabric, and the surface of the accordion cover 7 is coated with a stain-resistant coating. Nylon fabric has good flexibility, abrasion resistance and waterproof performance, while the stain-resistant coating can reduce the adhesion of dust and dirt, making the surface of the accordion cover 7 easier to clean.

[0032] Its working principle is as follows:

[0033] When using the tripod, the operator mounts the geodetic instrument on the tripod mounting platform 1. Then, the operator rotates the knobs 92 on both sides, causing the positioning rod 94 to move out of the positioning hole 4 on the surface of the tripod leg body 3. Next, the operator flips the movable plate 8 to a horizontal position. Then, the operator pulls the tripod leg body 3, causing the four sides of the tripod leg body 3 at the bottom of the mounting platform 2 to unfold. The operator inserts the positioning cone 5 into the soil below. The positioning cone 5 and the tripod leg body 3 support the tripod mounting platform 1 above. The operator can then use the geodetic instrument to perform measurements. After use, the operator first aligns the tripod leg body 3 to an upright position and flips the movable plate 8 to make it vertical. The operator then pulls down the lifting ring 6, which stretches the accordion cover 7, covering the tripod leg body 3 and the positioning cone 5. The operator moves the positioning block 95 to a position below the positioning cone 5 and aligns the positioning groove 96 with the positioning cones 5 on the left and right sides, so that the positioning cone 5 is inserted into the corresponding positioning groove 96, completing the positioning of the lifting ring 6. At this point, the operator can put the used tripod into the trunk of the car to prevent the mud or dirt on the tripod surface from polluting the surrounding area.

[0034] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
