Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a surveying benchmark that is easy to fix. Background Technology

[0002] Easy-to-fix surveying poles are tools used in engineering surveying, topographic mapping, and building construction to mark measurement points, provide vertical references, or assist in aiming. Their core feature is that their structural design allows for quick and stable fixing on the ground or other planes, ensuring the accuracy of measurement data.

[0003] A search revealed Chinese patent publication number CN219996197U, which discloses a surveying pole that is easy to fix, relating to the field of surveying tool technology. The technical solution includes a pole body and a fixing frame for fixing the pole. The fixing frame includes a cylindrical mounting base that inserts into the pole body. Several legs are rotatably mounted on the side wall of the mounting base. An adjusting plate is slidably mounted on the pole body. Several support rods are rotatably mounted on the adjusting plate, each support rod corresponding to one of the legs. A slider is rotatably mounted on the movable end of each support rod, and the slider is slidably connected to the support leg. The support leg has a groove on one side, and several limiting grooves are arranged in an array on the upper inner side of the groove. The slider slides in the groove, and two elastic arms are fixedly set on one side of the slider. Each elastic arm has a limiting block fixedly set at its movable end. The beneficial effect of this utility model is that it makes it easier for the operator to directly observe the state of the main body of the pole, and can avoid the problem of shaking and tilting the pole by hand, thus effectively improving the accuracy of measurement. However, in actual use, because a manual adjustment device is required, when encountering uneven ground, manual adjustment will cause the observation pole to be not straight, resulting in a reduction in its detection accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a surveying benchmark that is easy to fix, aiming to improve the problem that manual adjustment of the benchmark will cause it to be crooked when encountering uneven ground, thus reducing its detection accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surveying pole that is easy to fix, comprising a fixing plate, wherein a plurality of connecting seats 1 are fixedly connected to the outer wall of the fixing plate, a rotating rod 1 is rotatably connected inside the plurality of connecting seats 1, an electric telescopic rod is fixedly connected to the bottom of the outer wall of the plurality of rotating rods 1, a connecting seat 2 is provided at the bottom of the plurality of electric telescopic rods, a rotating rod 2 is rotatably connected inside the plurality of connecting seats 2, the bottom end of the plurality of electric telescopic rods is fixedly connected to the top of the outer wall of the rotating rod 2, a base plate is fixedly connected to the bottom of the plurality of connecting seats 2, a suction cup is fixedly connected to the bottom of the plurality of base plates, a level detector is fixedly connected to the top front side of the fixing plate, a measuring pole is slidably connected inside the fixing plate, and an adjustment mechanism is provided on the right side of the outer wall of the fixing plate.

[0006] Through the above technical solution: multiple connecting seats 1 are evenly distributed on the outer wall of the fixed plate. Each connecting seat 1 is equipped with a freely rotatable rotating rod 1. The suction cup on the bottom plate of the connecting seat 2 uses air pressure difference to adhere to the ground. The level detector monitors the level status in real time. If it is on an uneven ground, the level detector will detect the unevenness and send a signal, and the electric telescopic rod will be activated. With the help of the dual rotating nodes of connecting seat 1 and connecting seat 2, the ground height difference is compensated, so that the measuring rod is kept level and the measurement accuracy is improved.

[0007] As a further description of the above technical solution: The adjustment mechanism includes a threaded rod, the left end of which is threaded to the right side of the outer wall of the fixed plate. A threaded hole is provided on the right side of the outer wall of the fixed plate. The outer wall of the threaded rod is threaded to the inside of the threaded hole. Grooves are provided on both the front and rear sides of the interior of the fixed plate. Two fixing blocks are fixedly connected to the interior of the two grooves on opposite sides. Rotating wheels are rotatably connected between adjacent two fixing blocks on the front side and between adjacent two fixing blocks on the rear side.

[0008] The above technical solution involves rotating the threaded rod to the left, using the threaded transmission to press the end of the threaded rod against the marker rod, ensuring stable height during measurement. When adjusting the height, rotating the threaded rod outward releases the pressure, allowing the marker rod to move. The fixed block in the groove of the fixed plate supports the rotating wheel. When the marker rod moves up and down, the rotating wheel rotates synchronously, changing sliding friction into rolling friction, reducing resistance, minimizing component wear, extending the life of the mechanism, and improving the convenience and reliability of adjustment.

[0009] As a further description of the above technical solution: A lamp holder is fixedly connected to the top right side of the fixed plate, and a lighting lamp is rotatably connected to the top of the lamp holder.

[0010] The above technical solution involves fixing a lamp holder to the top right side of the fixed plate, with a lighting lamp rotatably connected to its top, allowing the lighting angle to be adjusted according to work needs and enhancing the brightness of the work area.

[0011] As a further description of the above technical solution: The threaded rod has an internal hexagonal groove on its right side, and the right side of the internal hexagonal groove is chamfered.

[0012] The above technical solution involves opening an internal hexagonal groove on the right side of the threaded rod, with a chamfered groove design to facilitate quick rotation of the wrench and improve operational efficiency.

[0013] As a further description of the above technical solution: Multiple anti-slip tubes are fixedly connected to the right side of the outer wall of the threaded rod, and the multiple anti-slip tubes adopt a ring design.

[0014] The above technical solution involves fitting multiple ring-shaped anti-slip tubes on the right side of the outer wall of the threaded rod. By increasing the roughness of the contact surface, the friction of the hand grip is enhanced, and the force can be applied stably even in wet and slippery environments, preventing slippage during adjustment.

[0015] As a further description of the above technical solution: Each of the multiple connecting seats 2 has a cap fixedly connected to its left and right sides, and the multiple caps are all designed symmetrically.

[0016] The above technical solution involves symmetrically designed caps fixedly connected to the left and right sides of multiple connecting seats 2, which effectively prevents the rotating rod 2 from falling off.

[0017] As a further description of the above technical solution: Multiple pads are fixedly connected to the inner bottom of the leveling instrument, and the multiple pads are arranged at equal intervals.

[0018] The above technical solution involves fixing multiple shims at equal intervals on the bottom inner side of the leveling instrument. When installing bolts, these shims can prevent the bolts from being overtightened.

[0019] As a further description of the above technical solution: The outer wall of the threaded rod matches the inside of the threaded hole, and multiple fixing blocks are equidistantly fixed inside the groove.

[0020] Through the above technical solution, the threaded rod and the threaded hole are precisely matched to ensure a tight connection and accurate thread transmission. Multiple fixing blocks are equidistantly distributed inside the groove, providing a stable support structure for the rotating wheel and ensuring the stability and reliability of the entire device.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the suction cup on the bottom plate of the connecting seat two uses air pressure difference to adhere to the ground, and the level detector monitors the level status in real time. If it is on an uneven ground, the level detector will send a signal to activate the electric telescopic rod. With the help of the double rotation nodes of the connecting seat one and the connecting seat two, the ground height difference is compensated, so that the measuring rod is kept level and the measurement accuracy is improved.

[0022] 2. In this utility model, rotating the threaded rod to the left causes the end of the threaded rod to press against the marker rod through the threaded transmission, ensuring stable height during measurement. When adjusting the height, rotating the threaded rod outward releases the pressure, allowing the marker rod to move. The fixed block in the groove of the fixed plate supports the rotating wheel. When the marker rod moves up and down, the rotating wheel rotates synchronously, changing sliding friction into rolling friction, reducing resistance, reducing component wear, extending the life of the mechanism, and improving the convenience and reliability of adjustment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a surveying marker that is easy to fix, comprising a fixing plate 1, a plurality of connecting seats 3 fixedly connected to the outer wall of the fixing plate 1, a rotating rod 4 rotatably connected inside each of the plurality of connecting seats 3, an electric telescopic rod 5 fixedly connected to the bottom of the outer wall of each of the plurality of rotating rods 4, the electric telescopic rod 5 being able to rotate with the rotating rod 4, a connecting seat 6 provided at the bottom of each of the plurality of electric telescopic rods 5, a rotating rod 7 rotatably connected inside each of the plurality of connecting seats 6, and the bottom ends of the plurality of electric telescopic rods 5 being fixedly connected to the top of the outer wall of the rotating rod 7. Connecting seat 2 6 can rotate with rotating rod 2 7. The bottom of multiple connecting seats 2 6 is fixedly connected to a base plate 8. The bottom of multiple base plates 8 is fixedly connected to a suction cup 9 for adhering to the ground. A level detector 10 is fixedly connected to the top front side of the fixed plate 1 for detecting whether it is on a level surface. A measuring rod 11 is slidably connected inside the fixed plate 1. When encountering uneven ground, one of the electric telescopic rods 5 extends and retracts. The angle is adjusted by rotating connecting seat 1 3 and connecting seat 2 6 to ensure that the measuring rod 11 is level. An adjustment mechanism 2 is provided on the right side of the outer wall of the fixed plate 1. Specifically, multiple connecting seats 3 are evenly distributed on the outer wall of the fixed plate 1. Each connecting seat 3 is equipped with a freely rotatable rotating rod 4. The lower end of the rotating rod 4 is fixedly connected to the electric telescopic rod 5, so that the electric telescopic rod 5 can rotate synchronously with the rotating rod 4. The bottom end of the electric telescopic rod 5 is connected to the connecting seat 6 through a rotating joint. The rotating rod 7 passes through the connecting seat 6 and forms a rotating connection, so that the connecting seat 6 can swing flexibly around the rotating rod 7. The bottom plate 8 fixed to the bottom of the connecting seat 6 is equipped with a suction cup 9 with vacuum adsorption function, which can be tightened by air pressure difference. The fixed plate 1 is closely fitted to the ground, providing stable support. The level detector 10 integrated at the front end can monitor whether the equipment is in a level state in real time. The measuring rod 11 is slidably assembled inside the fixed plate 1. When the equipment is placed on uneven ground, the electric telescopic rod 5 starts to extend and retract. At the same time, the dual rotating nodes of the connecting seat 1 3 and the connecting seat 2 6 are used to realize multi-dimensional angle adjustment, which can quickly compensate for the ground height difference and ensure that the measuring rod 11 always maintains a horizontal reference plane. This effectively improves the measurement accuracy under complex terrain and realizes the dual functions of adaptive leveling and stable support.

[0027] Reference Figure 3 and Figure 5The adjusting mechanism 2 includes a threaded rod 202. The left end of the threaded rod 202 is threaded to the right side of the outer wall of the fixing plate 1. A threaded hole 201 is provided on the right side of the outer wall of the fixing plate 1. The outer wall of the threaded rod 202 is threaded to the inside of the threaded hole 201. By rotating the threaded rod 202 to the left, the measuring rod 11 is squeezed to prevent it from moving. When it is necessary to adjust the height of the measuring rod 11, the threaded rod 202 is rotated outward. The front and rear sides of the interior of the fixing plate 1 are provided with grooves 203. Two fixing blocks 204 are fixedly connected to the side of the two grooves 203 that are far apart. Rotating wheels 205 are rotatably connected between the adjacent two front fixing blocks 204 and between the adjacent two rear fixing blocks 204. When the height of the measuring rod 11 is adjusted, the rotating wheels 205 contact the outer wall of the measuring rod 11, changing the sliding friction into rotational friction and reducing the friction force. Specifically, a threaded hole 201 is provided on the right side of the outer wall of the fixing plate 1. A threaded rod 202 is screwed into the hole through a threaded engagement. When it is necessary to fix the measuring rod 11, the threaded rod 202 is rotated to the left to press the end of the measuring rod 11. The self-locking characteristic of the threaded transmission is used to lock the position. When adjusting the height, the threaded rod 202 is rotated outward to release the pressure. The fixing plate 1 has grooves 203 on both the front and rear sides. Two fixing blocks 204 are fixedly connected to the side of each groove 203 away from the measuring rod 11. Rotating wheels 205 are rotatably connected between the front and rear sets of fixing blocks 204. When the measuring rod 11 slides up and down to adjust the height, the outer wall of the rotating wheel 205 contacts the measuring rod 11 and rotates synchronously, transforming the traditional sliding friction into rolling friction, significantly reducing the movement resistance, making the adjustment process smoother, reducing component wear, extending the service life of the mechanism, and improving the convenience and reliability of height adjustment.

[0028] Reference Figure 1 and Figure 2 A lamp holder 12 is fixedly connected to the top right side of the fixed plate 1. A lighting lamp 13 is rotatably connected to the top of the lamp holder 12 to increase the brightness of the working area. An internal hexagonal groove 14 is opened on the right side of the threaded rod 202. The right side of the internal hexagonal groove 14 is chamfered to facilitate the rotation of the threaded rod 202. Multiple anti-slip tubes 15 are fixedly connected to the right side of the outer wall of the threaded rod 202. The multiple anti-slip tubes 15 adopt a ring design to increase the friction with the hand. Specifically, the top right side of the fixed plate 1 is fixed to the lamp holder 12, and the top of the lamp 13 is rotatably connected to it. The lighting angle can be adjusted according to the work requirements to enhance the brightness of the working area. The right side of the threaded rod 202 has an internal hexagonal groove 14. The chamfered design of the groove makes it easy to adapt to the wrench for quick rotation and improves the operating efficiency. The right side of its outer wall is fitted with a multi-ring anti-slip tube 15, which increases the contact surface roughness to enhance the grip friction of the hand. Even in wet and slippery environments, it can apply force stably and avoid slipping during adjustment.

[0029] Reference Figure 1, Figure 4 and Figure 5 Multiple connectors 26 are fixedly connected to caps 16 on both sides. The caps 16 are symmetrically designed to prevent the rotating rod 27 from falling off. Multiple washers 17 are fixedly connected to the bottom inner side of the level detector 10. The washers 17 are equidistantly arranged to prevent the bolts from being tightened. The outer wall of the threaded rod 202 matches the inside of the threaded hole 201. Multiple fixing blocks 204 are equidistantly fixedly connected to the inside of the groove 203. Specifically, symmetrically designed caps 16 are fixedly connected to the left and right sides of multiple connecting seats 2 6, which can effectively prevent the rotating rod 2 7 from falling off. Multiple washers 17 are fixed at equal intervals on the inner bottom of the level detector 10. When installing bolts, these washers 17 can prevent the bolts from being overtightened. The threaded rod 202 and the threaded hole 201 are precisely matched to ensure that the two are tightly connected and can achieve precise thread transmission. Multiple fixing blocks 204 are equally distributed inside the groove 203, providing a stable support structure for the rotating wheel 205 and ensuring the stability and reliability of the entire device.

[0030] Working principle: When the equipment is placed on the ground, the suction cup 9 on the bottom plate 8 of the connecting seat 2 6 will adhere tightly to the ground through air pressure difference, providing initial stable support for the equipment. At this time, the level detector 10 integrated at the front end of the fixing plate 1 begins to monitor whether the equipment is in a horizontal state in real time. If the equipment is placed on uneven ground, the level detector 10 will detect that the equipment is not horizontal and send a signal. After receiving the signal, the electric telescopic rod 5 starts to extend and retract. At the same time, since the rotating rod 1 4 can rotate freely in the connecting seat 1 3, the rotating rod 2 7 passes through the connecting seat 2 6 to form a rotating connection. By using the dual rotating nodes of the connecting seat 1 3 and the connecting seat 2 6, multi-dimensional angle adjustment can be realized, quickly compensating for ground height difference, ensuring that the measuring rod 11 always maintains a horizontal reference plane, and effectively improving the measurement accuracy under complex terrain. Furthermore, when it is necessary to fix the height of the measuring rod 11, the operator rotates the threaded rod 202 to the left. Based on the principle of thread transmission, the threaded rod 202 will move to the left along the threaded hole 201, and its end will gradually approach and press against the measuring rod 11. That is, when the external force applied to rotate the threaded rod 202 is stopped, the threaded rod 202 will not rotate back on its own due to the reaction force of the measuring rod 11, thereby locking the position of the measuring rod 11 and ensuring its height stability during the measurement process. When it is necessary to adjust the height of the measuring rod 11, the operator rotates the threaded rod 202 outward, so that its end gradually moves away from the measuring rod 11, releasing the pressure on the measuring rod 11. The measuring rod 11 is no longer fixed and is in a movable state. In the grooves 203 on the front and rear sides inside the fixing plate 1, the fixing block 2... 04 provides a support and rotation basis for the rotating wheel 205. When the measuring rod 11 slides up and down to adjust its height, the outer wall of the measuring rod 11 contacts the rotating wheel 205. Since the rotating wheel 205 can rotate freely between the fixed blocks 204, the rotating wheel 205 will rotate synchronously with the measuring rod 11 as it moves. The original sliding friction between the measuring rod 11 and the fixed plate 1 is transformed into the rolling friction of the rotating wheel 205. Therefore, the motion resistance of the measuring rod 11 when adjusting its height is significantly reduced, making the adjustment process smoother. Rolling friction causes less wear on the components than sliding friction, thereby reducing component wear, extending the service life of the entire mechanism, and improving the convenience and reliability of height adjustment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
