Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, and in particular relates to a foldable field survey measuring rod. Background Technology

[0002] In geological exploration, engineering surveying, construction and other field surveying operations, the measuring rod is an indispensable basic measuring tool. Traditional measuring rods are usually integral long rod structures, which rely on scale markings or in conjunction with equipment such as total stations and theodolites to measure parameters such as distance, height and angle of target objects.

[0003] When conducting field measurements, integral measuring rods are difficult to adapt to measurement needs at different heights and lack flexible length adjustment functions. They often need to be paired with multiple measuring rods of different specifications, which increases the burden of carrying them. When measuring in mountainous areas, due to the undulating terrain, fixed-length measuring rods cannot accurately measure target points at different heights. In indoor space measurements, excessively tall measuring rods are difficult to operate due to space limitations.

[0004] To address these issues, we provide a foldable field surveying and measuring rod. Utility Model Content

[0005] The purpose of this invention is to provide a foldable field surveying and measuring rod. Through the cooperation of the folding positioning mechanism and the extension component, it solves the problem that the existing integral measuring rod is difficult to adapt to the measurement needs of different heights.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a foldable field surveying and measuring rod, comprising a sleeve. A folding positioning mechanism is fixedly connected to the surface of the sleeve, and an extension assembly is fixedly connected to the top of the sleeve. The folding positioning mechanism includes a motor, which is located at the top of the inner cavity of the sleeve. A lead screw is fixedly connected to the output end of the motor. The bottom of the lead screw is movably connected to the bottom of the inner cavity of the sleeve via a bearing. A threaded sleeve is threadedly connected to the surface of the lead screw, and three connecting blocks are fixedly connected to the surface of the threaded sleeve. The side of each connecting block away from the threaded sleeve extends to the outside of the sleeve. A connecting rod is movably connected to one side of each connecting block via a rotating shaft. An adjustment mechanism is provided on the surface of the connecting rod. When the motor drives the lead screw to rotate, the threaded sleeve moves up and down along the axis of the lead screw. The three connecting blocks are evenly distributed in a 120-degree circle on the surface of the threaded sleeve. The connecting blocks are fixedly connected to the threaded sleeve by welding to ensure connection strength. The connecting blocks extend to the outside through the movable groove on the surface of the sleeve. The end of the connecting block that extends out of the sleeve has a rotating shaft mounting hole. It is movably connected to the connecting rod through the rotating shaft to ensure that the connecting rod can rotate flexibly around the rotating shaft, realizing the folding and unfolding action of the measuring rod. The combination of motor driving screw and threaded sleeve can convert the rotational motion of the motor into the linear motion of the threaded sleeve. By controlling the number of rotations and direction of the motor, the support height of the measuring rod can be precisely adjusted. Compared with the traditional manual adjustment method, the efficiency and accuracy of height adjustment are greatly improved. It can quickly adapt to the height requirements of different measurement scenarios and reduce measurement preparation time.

[0008] The present invention is further configured such that the adjusting mechanism includes a sliding groove, the sliding groove being formed on the surface of the connecting rod, a sliding rod being slidably connected to the inner cavity of the sliding groove, an insert rod being fixedly connected to the bottom of the sliding rod, a sliding sleeve being fixedly connected to the top of the surface of the sliding rod, and a fastening rod being threadedly connected to the rear side of the sliding sleeve. The sliding fit between the sliding groove and the sliding rod allows the operator to freely adjust the angle and position of the connecting rod according to actual measurement needs. Whether it is necessary to tilt the measuring rod to align with the target when measuring in mountainous terrain, or to adjust the measuring angle in a narrow space, it can be easily achieved. The insert rod is directly inserted into the ground, and combined with the fastening effect of the sliding sleeve and the fastening rod, the measuring rod is firmly fixed at the target position.

[0009] The present invention is further configured such that a threaded post is threadedly connected to the bottom of the sleeve, and a ground nail is fixedly connected to the bottom of the threaded post. The ground nail, with its sharp head, can easily screw into soft ground such as soil and sand, thereby increasing the friction and grip with the ground and making the measuring rod firmly rooted.

[0010] The present invention is further configured such that the extension assembly includes a cylindrical body, the bottom of which is fixedly connected to a sleeve, an extension rod is provided in the inner cavity of the cylindrical body, and positioning seats are fixedly connected to the top of both sides of the cylindrical body. A screw is threadedly connected to the inner cavity of the positioning seat, and a movable sleeve is threadedly connected to the surface of the screw. A moving block is fixedly connected to the top of the movable sleeve, and a clamping plate is fixedly connected to one side of the moving block. One side of the clamping plate contacts the extension rod. Rotating the handwheel drives the screw to rotate, and the movable sleeve moves up and down along the screw. In turn, the clamping plate clamps or releases the extension rod through the moving block. This operation method is labor-saving and precise, and compared with the traditional manual plug-in length adjustment, it avoids the problems of plugging and unplugging jamming and loosening.

[0011] The present invention is further configured such that one side of the screw penetrates the inner cavity of the positioning seat and extends to the outside of the positioning seat, and a handwheel is fixedly connected to one side of the screw. The handwheel makes rotation easier and less strenuous, and can effectively reduce the fatigue of the workers, especially in measurement operations that require frequent adjustment of the extension rod length.

[0012] The present invention is further configured such that a positioning post is fixedly connected to the top of the extension rod, and the surface of the positioning post is provided with external threads. The positioning post and its external threads at the top of the extension rod are designed to facilitate quick connection of measuring accessories such as prisms and laser rangefinders.

[0013] The present invention is further configured such that a movable groove is formed on the surface of the sleeve, and the movable groove is slidably connected to the connecting block. The movable groove plays a guiding and limiting role for the connecting block. When the motor drives the threaded sleeve to move the connecting block up and down, the movable groove ensures that the connecting block can only slide smoothly along the axial direction of the sleeve, effectively limiting the radial displacement and swing of the connecting block.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a motor to drive a lead screw to rotate, which in turn moves a threaded sleeve up and down along the lead screw. This allows for rapid adjustment of the support height of the measuring rod via a connecting block and a connecting rod. Compared to traditional manual adjustment, the motor drive can quickly adjust the measuring rod to the required height, greatly improving measurement preparation efficiency. At the same time, the motor drive, combined with the lead screw thread structure, enables precise height adjustment, effectively meeting the height accuracy requirements of different measurement scenarios and ensuring the accuracy of measurement data.

[0016] 2. This utility model uses a rotating handwheel to drive the screw, causing the movable sleeve to move up and down along the screw, which in turn causes the clamping plate to clamp or loosen the extension rod, thus achieving flexible adjustment of the length between the cylinder and the extension rod. This design can quickly adapt to measurement scenarios of different heights and distances, eliminating the need to carry multiple measuring rods and effectively reducing the burden on workers.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6This utility model is a foldable field surveying and measuring rod, including a sleeve 1. A folding positioning mechanism 2 is fixedly connected to the surface of the sleeve 1. An extension component 3 is fixedly connected to the top of the sleeve 1. The folding positioning mechanism 2 includes a motor 21, which is located at the top of the inner cavity of the sleeve 1. A lead screw 22 is fixedly connected to the output end of the motor 21. The bottom of the lead screw 22 is movably connected to the bottom of the inner cavity of the sleeve 1 through a bearing. A threaded sleeve 23 is threadedly connected to the surface of the lead screw 22. A connecting block 24 is fixedly connected to the surface of the threaded sleeve 23. There are three connecting blocks 24. The side of the connecting block 24 away from the threaded sleeve 23 extends to the outside of the sleeve 1. A connecting rod 25 is movably connected to one side of the connecting block 24 through a rotating shaft. An adjustment mechanism 26 is provided on the surface of the connecting rod 25.

[0028] Specifically: When the motor 21 drives the lead screw 22 to rotate, the threaded sleeve 23 moves up and down along the axis of the lead screw 22. Three connecting blocks 24 are evenly distributed on the surface of the threaded sleeve 23 in a 120-degree circle. The connecting blocks 24 and the threaded sleeve 23 are fixedly connected by welding to ensure the connection strength. The connecting blocks 24 extend to the outside through the movable groove 8 on the surface of the sleeve 1. The end of the connecting block 24 that extends out of the sleeve 1 is provided with a rotating shaft mounting hole. It is movably connected to the connecting rod 25 through the rotating shaft to ensure that the connecting rod 25 can rotate flexibly around the rotating shaft, realizing the folding and unfolding action of the measuring rod. The combination of the motor 21 driving the lead screw 22 and the threaded sleeve 23 can convert the rotational motion of the motor 21 into the linear motion of the threaded sleeve 23. By controlling the number of rotations and the direction of the motor 21, the height of the measuring rod can be precisely adjusted. Compared with the traditional manual adjustment method, the efficiency and accuracy of height adjustment are greatly improved, and it can quickly adapt to the height requirements of different measurement scenarios and reduce the measurement preparation time.

[0029] Example 2

[0030] Please see Figure 1-6Based on Embodiment 1, the adjusting mechanism 26 includes a slide groove 261, which is formed on the surface of the connecting rod 25. A sliding rod 262 is slidably connected to the inner cavity of the slide groove 261. An insert rod 263 is fixedly connected to the bottom of the sliding rod 262. A sliding sleeve 264 is fixedly connected to the top of the surface of the sliding rod 262. A fastening rod 265 is threadedly connected to the rear side of the sliding sleeve 264. A threaded post 4 is threadedly connected to the bottom of the sleeve 1. A ground nail 5 is fixedly connected to the bottom of the threaded post 4. The extension assembly 3 includes a cylinder 31, the bottom of which is fixedly connected to the sleeve 1. An extension rod 32 is provided in the inner cavity of the cylinder 31. The cylinder 31 has extension rods on both sides. The top of each part is fixedly connected to a positioning seat 33. The inner cavity of the positioning seat 33 is threadedly connected to a screw 34. The surface of the screw 34 is threadedly connected to a movable sleeve 35. The top of the movable sleeve 35 is fixedly connected to a moving block 36. One side of the moving block 36 is fixedly connected to a clamping plate 37. One side of the clamping plate 37 contacts the extension rod 32. One side of the screw 34 passes through the inner cavity of the positioning seat 33 and extends to the outside of the positioning seat 33. One side of the screw 34 is fixedly connected to a handwheel 6. The top of the extension rod 32 is fixedly connected to a positioning pin 7. The surface of the positioning pin 7 is provided with external threads. The surface of the sleeve 1 is provided with a movable groove 8. The movable groove 8 is slidably connected to the connecting block 24.

[0031] Specifically: The sliding engagement of the groove 261 and the sliding rod 262 allows staff to freely adjust the angle and position of the connecting rod 25 according to actual measurement needs. Whether it is necessary to tilt the measuring rod to align with the target when measuring in mountainous terrain, or to adjust the measuring angle in a narrow space, it can be easily achieved. The insertion rod 263 is directly inserted into the ground, and combined with the fastening effect of the sliding sleeve 264 and the fastening rod 265, the measuring rod is firmly fixed in the target position. The ground stake 5, with its sharp head, can easily screw into soft ground such as soil and sand, increasing the friction and grip with the ground, so that the measuring rod is firmly rooted. Turning the handwheel 6 drives the screw 34 to rotate, and the movable sleeve 35 moves up and down along the screw 34, which in turn moves the movable block 36. The clamping plate 37 clamps or releases the extension rod 32. This operation method is labor-saving and precise. Compared with the traditional manual plug-and-play length adjustment, it avoids the problems of plugging and unplugging jamming and loosening. The handwheel 6 makes rotation easier and less strenuous. Especially in measurement operations that require frequent adjustment of the length of the extension rod 32, it can effectively reduce the fatigue of the operator. The positioning post 7 at the top of the extension rod 32 and its external thread design facilitate quick connection of measurement accessories such as prisms and laser rangefinders. The movable groove 8 guides and limits the connecting block 24. When the motor 21 drives the threaded sleeve 23 to move the connecting block 24 up and down, the movable groove 8 ensures that the connecting block 24 can only slide smoothly along the axial direction of the sleeve 1, effectively limiting the radial displacement and swing of the connecting block 24.

[0032] The working principle of this utility model is as follows: When the motor 21 is started, the motor 21 drives the lead screw 22 to rotate. The rotational motion of the lead screw 22 is converted into linear motion of the threaded sleeve 23 along the axis of the lead screw 22. The connecting block 24 moves synchronously with the threaded sleeve 23. The connecting block 24 transmits the motion to the connecting rod 25. When the threaded sleeve 23 moves upward, the connecting rod 25 opens outward around the axis of rotation, and the measuring rod unfolds and gradually rises. When the threaded sleeve 23 moves downward, the connecting rod 25 retracts around the axis of rotation towards the sleeve 1, and the measuring rod folds and lowers in height. By controlling the forward and reverse rotation and the number of rotations of the motor 21, the moving distance of the threaded sleeve 23 is controlled, thereby achieving precise adjustment of the support height of the measuring rod.

[0033] When the support angle needs to be adjusted, the operator first loosens the fastening rod 265 to reduce the friction between the sliding sleeve 264 and the sliding rod 262, allowing the sliding rod 262 to slide freely within the groove 261. Based on the actual measurement requirements, the operator pushes the sliding rod 262 to a suitable position within the groove 261. At this time, the sliding rod 262 drives the insertion rod 263 to move synchronously, adjusting the tilt angle of the connecting rod 25. After the angle adjustment is complete, the fastening rod 265 is tightened, causing the sliding sleeve 264 to press tightly against the sliding rod 262. Friction is used to fix the sliding rod 262 within the groove 261, thus locking the angle of the connecting rod 25. On soft or uneven ground, the insertion rod 263 can be directly inserted into the ground, further enhancing the stability of the measuring rod and preventing shaking or displacement during measurement.

[0034] When the length needs to be adjusted, the operator turns the handwheel 6, which drives the screw 34 to rotate. Since the screw 34 and the movable sleeve 35 are connected by a thread, the rotational motion of the screw 34 is converted into the linear motion of the movable sleeve 35 along the axis of the screw 34. The moving block 36 at the top of the movable sleeve 35 moves synchronously with the movable sleeve 35, causing the clamping plate 37 to move closer to or away from the extension rod 32. When the clamping plate 37 releases the extension rod 32, the extension rod 32 can slide freely inside the cylinder 31. The operator can pull out or push the extension rod 32 to the appropriate length as needed, and then turn the handwheel 6 in the opposite direction to make the clamping plate 37 clamp the extension rod 32. The friction between the clamping plate 37 and the extension rod 32 is used to fix the extension rod 32 in the current position.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described.
