[0002] Engineering surveying refers to various surveying work carried out during the surveying, design, construction, and management phases of engineering construction. It includes instruments and devices designed and manufactured for data acquisition, processing, and output for surveying operations, as well as various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry required for surveying work during the planning, design, construction, and operation management phases of engineering construction.

[0003] However, the support frame of some existing surveying instrument stabilizers has an inverted cone shape at the bottom, which makes it easy to insert into the soil and thus easy to install. However, due to the instability of the inverted cone, it is easy to wobble, which can cause the stable support to be unstable or wobble. It is also inconvenient to store, and it is impossible to determine whether the surveying instrument is perpendicular to the ground. Therefore, there is an urgent need for a surveying instrument stabilizer for engineering surveying to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a stabilizer for a surveying instrument used in engineering surveying, so as to solve the problem mentioned in the background art that the bottom of the support frame of some existing surveying instrument stabilizers is inverted cone-shaped. Due to the instability of the inverted cone, it is easy to wobble, which can easily cause the stable support to be placed unstable or wobble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stabilizer for an engineering surveying instrument, comprising a support frame, a leveling structure, and a surveying instrument body. The support frame includes a support plate, the outer wall of which is rotatably connected to a support rod via a hinge. A support pad is fixedly connected to the bottom of the support rod, and a fixed seat is fixedly connected to the top of the support pad. The fixed seat is threadedly connected to a threaded rod, and a drill rod is fixedly connected to the bottom of the threaded rod. The leveling structure includes a fixed plate, the top of which is fixedly connected to the support plate. Three ball joints are movably connected to the top of the fixed plate, and a threaded rod is fixedly connected to the top of each ball joint. The threaded rod is threadedly connected to a fixed rod, and the top of the fixed rod is rotatably connected to a ball joint. The ball joint is movably connected to a fixed plate, and the top of the fixed plate is fixedly connected to the surveying instrument body.

[0006] Preferably, a fixing rod is fixedly connected to the bottom of the support plate, a fixing ring is fixedly connected to the outer wall of the bottom end of the fixing rod, and three buckles are fixedly connected to the outer wall of the fixing ring.

[0007] Preferably, the buckle engages with the support rod, the buckle is a C-shaped buckle, the buckle is made of nylon and has a certain degree of elasticity.

[0008] Preferably, the top of the threaded rod is fixedly connected to the handle, and the surface of the handle is provided with an anti-slip coating.

[0009] Preferably, the top of the fixing plate one is fixedly connected to the fixing rod two, the outer wall of the fixing rod two is rotatably connected to one end of the telescopic rod through a hinge, and the other end of the telescopic rod is rotatably connected to the outer wall of the ball joint one through a hinge.

[0010] Preferably, the top of the ball joint two is fixedly connected to the handle two, the handle two is a hexagonal handle, and the surface is provided with an anti-slip coating.

[0011] Preferably, the support pad has a circular hole in the middle, and the diameter of the circular hole is larger than the diameter of the drill rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of engineering surveying instrument stabilizer is equipped with a support frame. When the surveying instrument body needs to be placed on the ground, the support rod is pulled so that it is no longer locked in the buckle, allowing the support pad to support the ground. The handle is rotated so that the handle drives the threaded rod to rotate. The threaded rod drives the drill rod to move downwards and rotate, so that the drill rod drills into the soil to act as a support column. The drilled soil is discharged through the round hole of the support pad. The support frame not only makes the surveying instrument body stably fixed on the ground, but also makes it easy to store, improving portability.

[0014] 2. This type of stabilizer for engineering surveying instruments is equipped with a leveling structure. When the instrument body needs to be leveled, the level is placed on the fixed plate two. By rotating the handle two, the handle two drives the ball joint two and the fixed rod to rotate. Since the threaded rod is restricted from rotating by the telescopic rod, the fixed rod can move up and down. Through the ball joint two and the ball joint one, the fixed rod and the threaded rod can adapt to different support angles. When the support angle of the fixed rod and the threaded rod changes, the telescopic rod can extend and retract freely. The leveling structure can quickly adjust the support angle of the fixed plate two, so that the instrument body is on a horizontal plane. The operation is simple and convenient, and easy to use.

[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 refer to Figures 1-5. One embodiment of this utility model provides a stabilizer for an engineering surveying instrument, including a support frame 1, a leveling structure 2, and the instrument body 3. The support frame 1 includes a support plate 11. The outer wall of the support plate 11 is rotatably connected to a support rod 15 via a hinge. The bottom of the support rod 15 is fixedly connected to a support pad 16, and the top of the support pad 16 is fixedly connected to a fixing seat 17. The fixing seat 17 is threadedly connected to a threaded rod 18, and the bottom of the threaded rod 18 is fixedly connected to a drill rod 19. The leveling structure 2 includes a fixing plate 21, and the top of the support plate 11 is fixedly connected to the fixing plate 21. The top of the device is movably connected to three ball joints 23. The top of the ball joints 23 is fixedly connected to a threaded rod 25. The threaded rod 25 is threadedly connected to a fixing rod 26. The top of the fixing rod 26 is rotatably connected to a ball joint 27. The ball joint 27 is movably connected to a fixing plate 29. The top of the fixing plate 29 is fixedly connected to the surveying instrument body 3. The support frame 1 not only allows the surveying instrument body 3 to be stably fixed on the ground, but also facilitates storage and improves portability. The leveling structure 2 allows for quick adjustment of the support angle of the fixing plate 29, so that the surveying instrument body 3 is on a horizontal plane. The operation is simple and convenient, and it is easy to use.

[0023] Furthermore, a fixing rod 12 is fixedly connected to the bottom of the support plate 11, and a fixing ring 13 is fixedly connected to the outer wall of the bottom end of the fixing rod 12. Three buckles 14 are fixedly connected to the outer wall of the fixing ring 13. The buckles 14 engage the support rod 15. The buckles 14 are C-shaped buckles made of nylon and have a certain degree of elasticity. Pulling the support rod 15 will cause the support rod 15 to no longer be engaged in the buckles 14. The position of the support rod 15 is fixed by the buckles 14, thereby storing the support rod 15.

[0024] Furthermore, the top of the threaded rod 18 is fixedly connected to the handle 110. The surface of the handle 110 is provided with an anti-slip coating to prevent slippage when rotating the handle 110. The four grips of the handle 110 make it easier to rotate.

[0025] Furthermore, the top of the fixed plate 21 is fixedly connected to the fixed rod 22. The outer wall of the fixed rod 22 is rotatably connected to one end of the telescopic rod 24 via a hinge. The other end of the telescopic rod 24 is rotatably connected to the outer wall of the ball joint 23 via a hinge. Since the threaded rod 25 is restricted from rotating by the telescopic rod 24, the fixed rod 26 can move up and down. When the fixed rod 26 and the threaded rod 25 change their support angle, the telescopic rod 24 can extend and retract freely.

[0026] Furthermore, the top of the ball joint 27 is fixedly connected to the handle 28, which is a hexagonal handle with an anti-slip coating on its surface. The anti-slip coating prevents slippage when rotating the handle 28, and the hexagonal handle is easier to hold.

[0027] Furthermore, a circular hole is provided in the middle of the support pad 16, and the diameter of the circular hole is larger than the diameter of the drill rod 19. The threaded rod 18 drives the drill rod 19 to move downward and rotate at the same time, so that the drill rod 19 drills into the soil to act as a support column, and the drilled soil is discharged through the circular hole of the support pad 16.

[0028] Working principle: In use, when the surveying instrument body 3 needs to be placed on the ground, pull the support rod 15 so that it is no longer locked in the buckle 14, allowing the support pad 16 to support the ground. Rotate the handle 110, causing the threaded rod 18 to rotate. The threaded rod 18 drives the drill rod 19 to move downwards and rotate, allowing the drill rod 19 to drill into the soil and act as a support column. The drilled soil is discharged through the round hole of the support pad 16. The support frame 1 not only allows the surveying instrument body 3 to be stably fixed on the ground, but also facilitates storage and improves portability. When leveling the surveying instrument body 3 is required, the support frame 1 can be used to stabilize the surveying instrument body 3 on the ground. The level is placed on the fixed plate 29. By rotating the handle 28, the handle 28 drives the ball joint 27 and the fixed rod 26 to rotate. Since the threaded rod 25 is restricted from rotating by the telescopic rod 24, the fixed rod 26 can move up and down. The fixed rod 26 and the threaded rod 25 can adapt to different support angles through the ball joint 27 and the ball joint 23. When the support angle of the fixed rod 26 and the threaded rod 25 changes, the telescopic rod 24 can extend and retract freely. The support angle of the fixed plate 29 can be quickly adjusted through the leveling structure 2, so that the surveying instrument body 3 is on the horizontal plane. The operation is simple and convenient, and easy to use.

[0029] 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
