Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to an adjustable support for engineering surveying and mapping. Background Technology

[0002] Engineering surveying and mapping is the process of converting geospatial information into specific digital models. Its applications are wide-ranging, including building construction, land planning, infrastructure construction, and mineral resource extraction. In the process of engineering surveying and mapping, adjustable supports are a common tool used to support and adjust the position and angle of surveying or mapping equipment.

[0003] Traditional surveying and mapping supports are usually made of iron or wood, which have problems such as low strength or poor portability. When in use, the legs are not restrained and are easy to slide. When the legs are opened, they take up a lot of space. Surveyors often have to straddle the legs to use instruments, which can easily cause them to bump into the legs. The base uses pointed feet, which can slip on relatively smooth and flat surfaces, affecting measurement accuracy and efficiency.

[0004] Therefore, we provide an adjustable support for engineering surveying and mapping. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable support for engineering surveying and mapping, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable support for engineering surveying and mapping, comprising a main body and a leg mechanism. The bottom of the main body is connected to one end of a short shaft, and the other end of the short shaft is connected to the leg mechanism and an upper leg. A lower leg is provided on the inner side of the upper leg. A buckle is provided on the front of the upper leg. A fixing rod is provided on the left side of the upper leg. A fixing hole is provided on the right side of the upper leg. A locking bolt is provided below the fixing hole. A rotating sleeve is provided at the bottom of the lower leg. A pedal is provided on the front of the lower leg. A foot is provided below the pedal. The back of the foot is connected to one end of a hinge, and the other end of the hinge is connected to a rubber base.

[0007] Preferably, the main body is rotatably connected to the upper support leg via a short shaft, and the upper support leg is made of aluminum alloy.

[0008] Preferably, the upper support leg and the buckle are threaded together, and the lower support leg and the buckle are snapped together.

[0009] Preferably, the upper support leg and the fixing rod are threaded together, and the fixing rod and the fixing hole are snap-fitted together.

[0010] Preferably, the upper support leg is rotatably connected to the rotating sleeve via a locking bolt, and the lower support leg is sized to match the rotating sleeve.

[0011] Preferably, the lower support leg and the pedal are welded together, and the lower support leg and the pedal are sized to match.

[0012] Preferably, the support leg is rotatably connected to the rubber base via a hinge, and the support leg and the groove of the rubber base are sized to match.

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

[0014] The adjustable support used for surveying and mapping in this project reduces weight while maintaining strength through the use of aluminum alloy legs, making it easy to move. The use of fixing rods and fixing holes prevents the legs from slipping and ensures stability.

[0015] By using clips and rotating sleeves, the lower outriggers can be set perpendicular to the ground, preventing collisions that could cause the instrument to lose accuracy and affect measurement efficiency when straddling the outriggers during operation. The use of rubber bases prevents the outriggers from slipping on smooth and flat surfaces, thus maintaining good stability on soft soil and paved ground. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an adjustable support for engineering surveying and mapping, including a main body 1 and a leg mechanism 3. The bottom of the main body 1 is connected to one end of a short shaft 2, and the other end of the short shaft 2 is connected to the leg mechanism 3. The other end of the short shaft 2 is connected to an upper support leg 301. A lower support leg 302 is provided on the inner side of the upper support leg 301. A buckle 303 is provided on the front of the upper support leg 301. A fixing rod 304 is provided on the left side of the upper support leg 301. A fixing hole 305 is provided on the right side of the upper support leg 301. A locking bolt 306 is provided below the fixing hole 305. A rotating sleeve 307 is provided at the bottom of the lower support leg 302. A pedal 308 is provided on the front of the lower support leg 302. A foot 309 is provided below the pedal 308. The back of the foot 309 is connected to one end of a hinge 310. The other end of the hinge 310 is connected to a rubber base 311.

[0023] Furthermore, the main body 1 is rotatably connected to the upper support leg 301 via the short shaft 2. The upper support leg 301 is made of aluminum alloy, which has good toughness, strong impact resistance, low density but high strength, and good plasticity.

[0024] Furthermore, the upper support leg 301 is threadedly connected to the buckle 303, and the lower support leg 302 is snapped into place with the buckle 303. When not in use, the buckle 303 secures the lower support leg 302 to the upper support leg 301 for easy storage.

[0025] Furthermore, the upper support leg 301 is threadedly connected to the fixing rod 304, and the fixing rod 304 is snapped into the fixing hole 305. During use, the fixing rod 304 is snapped into the fixing hole 305 to prevent the support leg from sliding and ensure stability.

[0026] Furthermore, the upper support leg 301 is rotatably connected to the rotating sleeve 307 via the locking bolt 306, and the lower support leg 302 is sized to match the rotating sleeve 307. The rotating sleeve 307 makes the lower support leg 302 perpendicular to the ground, reducing the footprint of the support leg, facilitating the use of the instrument, and ensuring the maximum contact area between the rubber base 311 and the ground.

[0027] Furthermore, the lower support leg 302 is welded to the pedal 308, and the dimensions of the lower support leg 302 and the pedal 308 are matched, making it convenient to fix the support foot 309 on the soft ground.

[0028] Furthermore, the support leg 309 is rotatably connected to the rubber base 311 via the hinge 310. The groove size of the support leg 309 and the rubber base 311 are matched. When the rubber base 311 is used on a relatively smooth surface, the friction is increased, which plays a role in preventing slippage.

[0029] Working principle: Install the bracket in the working position, first open the upper support leg 301, fix the fixing rod 304 in the fixing hole 305, fix the upper support leg 301 to prevent slippage, loosen the buckle 303 and the locking bolt 306, extend the lower support leg 302 to the required length, and then tighten the locking bolt 306. Step the foot 309 into the ground and fix it through the pedal 308. If the ground is hard, rotate the rubber base 311 and put it on the foot 309. This completes the use process of an adjustable bracket for engineering surveying and mapping.

[0030] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
