Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping engineering, in particular to a surveying and mapping benchmark pole which is easy to fix. Background Art

[0002] Surveying poles are used in surveying and mapping projects to assist with instrument positioning, calibrate surveying locations, and provide a precise height reference. Traditional surveying poles consist of a base pole and a retractable or extendable extension pole, allowing for flexible height adjustments to meet diverse surveying needs.

[0003] Currently, common surveying and mapping benchmarks on the market usually use two connection schemes when adding extension poles: one is a threaded connection method, in which the bottom end of the extension pole is screwed into the threaded mouth of the base pole. This method requires surveying and mapping personnel to hold the extension pole tightly with their hands to keep it stable under the influence of wind; the other is a method in which the lower pole is connected to the upper pole. The base pole has a hollow structure inside, and after inserting the upper pole, it can be pulled out to adjust the height.

[0004] However, regardless of the method, the upper pole is prone to swaying in the wind, requiring surveyors to constantly hold the connection to prevent the extended pole from bending, which can lead to measurement deviations or even measurement failures. This makes securing the upper pole very inconvenient in actual use. The inability to solve the problem of pole swaying and bending has affected the convenience and reliability of surveying and mapping work. Therefore, there is an urgent need for a surveying and mapping pole that is easy to fix and can address the above-mentioned technical shortcomings. Utility Model Content

[0005] The purpose of the utility model is to provide a surveying and mapping benchmark that is easy to fix, so as to solve the problem in the above background technology that the upper pole is easy to shake under the action of wind, and the surveying and mapping personnel need to hold the connection point at all times, which is inconvenient to fix.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surveying and mapping benchmark for surveying and mapping projects that is easy to fix, comprising a base benchmark and a fixing seat, an insert sleeve welded in the middle position of the fixing seat, the base benchmark being inserted into the insert sleeve, a fixing disk being processed at the top end of the base benchmark, and a quick fixing structure being provided above the fixing seat; the quick fixing structure comprises a group of extension rods connected to the fixing disk at the bottom end, a threaded opening being sleeved on the outside of the fixing disk, a rotating column being fixed to the top edge of the threaded opening, a windproof rope being wound around the rotating column, a coil spring being installed at the rotating column, three groups of hooks being provided at the bottom end of the fixing seat, and the bottom ends of the windproof ropes being hooked to the hooks.

[0007] Preferably, the threaded opening and the fixing seat are both disc-shaped, the fixing seat is fixedly sleeved on the outside of the base pole, and the centers of the fixing seat and the fixing disc are located on the same vertical line.

[0008] Preferably, the extension rod and the base rod are of the same length, and a threaded sleeve for placing the extension rod is welded on one side of the bottom end of the fixing seat.

[0009] Preferably, a mounting column is welded to the right side of the bottom end of the fixing seat, a hinge seat is installed at the mounting column, a flippable clamp is connected to the hinge seat, and the clamp is a semi-arc metal component.

[0010] Preferably, a locking bolt is installed at the clamp, and the curvature of the clamp matches the base pole and the extension pole.

[0011] Preferably, four groups of sliding grooves are opened on the outer wall of the lower half of the base pole, and the sliding grooves are evenly distributed around the base pole, and sliding seats are embedded in the sliding grooves.

[0012] Preferably, the slide seats are hinged with connecting rods, the bottom ends of the connecting rods are hinged with positioning angle blocks, and the tops of the positioning angle blocks are equipped with positioning bolts.

[0013] Preferably, a chassis is welded to the bottom end of the extension rod, and four groups of jacks are distributed around the top of the chassis.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the surveying and mapping benchmark pole that is easy to fix not only achieves better windproof and anti-bending effects by quickly fixing the extension pole, but also achieves better mobile storage function without the need for auxiliary fasteners such as containers and binding ropes, and can adapt to uneven surfaces, and has better ground-piercing flexibility;

[0015] (1) The pole is composed of a base pole at the lower half and an extension pole at the upper half, and is provided with an extension pole, a fixing plate, a threaded opening, a rotating column, a windproof rope, a hook, an insert, and a coil spring. In addition to the traditional threaded opening connection method, a set of fixing plates and a set of fixing seats are added. After the bottom end of the extension pole is aligned with the threaded opening and screwed together, the windproof ropes at the four sets of rotating columns are pulled out one by one, and under the rotation of the rotating column, the windproof ropes are unwound and pulled to the hook at the bottom end of the fixing seat and fastened, thereby forming a stable support for the extension pole, avoiding shaking or bending of the extension pole at the connection point, and achieving better windproof and anti-bending effects by quickly fixing the extension pole;

[0016] (2) A threaded sleeve, a fixing seat, a mounting column, a hinged seat, a locking bolt, and a clamp are provided. A threaded sleeve is provided on one side of the bottom end of the fixing seat. After the surveying is completed, the extension rod is removed and screwed into the threaded sleeve so that the extension rod and the base pole are parallel. The clamp is then flipped and clamped into the extension rod and the base pole through the hinged seat and tightened separately with the locking bolt. The extension rod and the base pole can be fixed side by side, making it easy to carry when not in use. No auxiliary fasteners such as containers and binding ropes are required, thereby achieving a better mobile storage function.

[0017] (3) The lower half of the base pole is provided with four sets of liftable slides through the slides. After the surveying is completed, the connecting rod is slid up through the slide until the connecting rod is vertical, and the bottom end of the positioning bolt is embedded in the corresponding socket for storage. When the base pole is used for surveying, the slide is pulled down and out, and the angle is changed through the connecting rod. The positioning bolts are used to fix the positioning angle blocks to the surrounding plane. Since the connecting rod can be adjusted at different angles, it can adapt to uneven planes and has better flexibility in ground engagement. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, if Figure 1 and Figure 2 As shown, the benchmark consists of a base benchmark 14 in the lower half and an extension rod 1 in the upper half. A set of fixing plates 2 and a set of fixing seats 9 are added to the traditional threaded opening 3 connection method. After the bottom end of the extension rod 1 is aligned with the threaded opening 3 and screwed together, the windproof ropes 5 at the four sets of rotating columns 4 are pulled out one by one, and under the rotation of the rotating column 4, the windproof ropes 5 are unwound and pulled to the hook 6 at the bottom end of the fixing seat 9 to be fastened, forming a stable support for the extension rod 1 to prevent the extension rod 1 from shaking or bending at the connection.

[0026] The extension rod 1 and the base pole 14 are the same length. A threaded sleeve 8 for placing the extension rod 1 is welded to one side of the bottom end of the fixing seat 9.
